本发明涉及泄洪闸门启闭机的应急驱动领域，特别涉及一种用于泄洪闸的无电应急智能液压快速操作系统。The invention relates to the field of emergency driving of a flood discharge gate hoist, and in particular to a non-electric emergency intelligent hydraulic rapid operating system for a flood discharge gate.
背景技术Background Art
泄洪闸是水坝及电站可靠运行的必要保障，通常依赖于电力驱动的液压系统来控制闸门的启闭。当电力中断或系统发生故障时，传统的电动操作系统无法正常工作，导致泄洪闸无法及时开启或关闭，严重影响防洪和排涝的效率和安全性。因此，设计一种在原系统无电或发生故障的情况下，仍能迅速、智能、可靠地操作泄洪闸的液压操作系统，具有重要的实际意义。Flood gates are essential for the reliable operation of dams and power stations, and usually rely on electrically driven hydraulic systems to control the opening and closing of the gates. When power is interrupted or the system fails, the traditional electric operating system cannot work properly, resulting in the failure to open or close the flood gates in time, which seriously affects the efficiency and safety of flood control and drainage. Therefore, it is of great practical significance to design a hydraulic operating system that can quickly, intelligently and reliably operate the flood gates when the original system is out of power or fails.
现有的泄洪闸应急操作系统在智能化、响应速度和可靠性方面仍存在不足。在无电或系统故障的情况下，传统应急系统无法智能切换至应急操作模式。大多数系统依赖于人工干预来启动应急操作，这不仅需要操作人员迅速到达现场，还要求具备专业的操作技能。在实际情况中，这种方式既耗时又存在较大的误操作风险。The existing emergency operation system for flood discharge gates still has deficiencies in terms of intelligence, response speed and reliability. In the event of power outage or system failure, the traditional emergency system cannot intelligently switch to emergency operation mode. Most systems rely on manual intervention to initiate emergency operations, which not only requires operators to arrive at the scene quickly, but also requires professional operating skills. In actual situations, this method is time-consuming and has a high risk of misoperation.
另外，传统的应急操作系统响应速度慢。由于依赖机械装置或手动操作，这些系统无法迅速调整和精确快速控制泄洪闸的开启和关闭。在洪水等紧急情况下，这种延迟可能导致灾害的加剧，无法有效保护人员和财产安全。In addition, traditional emergency operation systems have a slow response speed. Due to their reliance on mechanical devices or manual operation, these systems cannot quickly adjust and accurately and quickly control the opening and closing of flood gates. In emergency situations such as floods, this delay may lead to the aggravation of disasters and fail to effectively protect the safety of people and property.
为了解决上述问题，本发明提供了一种用于泄洪闸的无电应急智能液压快速操作系统，主要由液压控制子系统、信号控制子系统、状态测控子系统构成，具有高度智能、快速响应和高可靠性等特点，能够在无电或系统发生故障时高效地实现对泄洪闸的可靠操作，确保大坝泄洪安全，消除洪水漫坝或溃坝的重大安全隐患。In order to solve the above problems, the present invention provides an off-electricity emergency intelligent hydraulic rapid operation system for a flood gate, which is mainly composed of a hydraulic control subsystem, a signal control subsystem, and a state measurement and control subsystem. It has the characteristics of high intelligence, rapid response, and high reliability. It can efficiently realize reliable operation of the flood gate when there is no electricity or a system failure, ensure the safety of dam flood discharge, and eliminate major safety hazards of flood overflow or dam breach.

液压控制子系统的动力单元由柴油机3驱动齿轮泵2，通过发电机4提供电力支持。当原系统22失电时，继电器线圈21会动作，使继电器常开触点28闭合；或者当原系统22发生故障时，信号控制器29检测到故障并激活继电器线圈21，使继电器常开触点28闭合，从而快速智能切换到应急操作模式，启动柴油机3，驱动齿轮泵2进行工作。齿轮泵2通过吸油过滤器1从油箱26吸油，并将液压油输入系统中。液压油首先通过第三单向阀5进入液压控制回路。电磁溢流阀6用于维持操作系统压力恒定，并防止过载。液压油经过第一调速阀10、第二调速阀17、第一单向阀11、第二单向阀16、第一两位二通电磁球阀9、第二两位二通电磁球阀18、第一电液伺服阀8、第二电液伺服阀19以及第一背压阀7、第二背压阀20的联合控制，通过第一两位三通电磁球阀12和第二两位三通电磁球阀15分别进入第一液压缸13和第二液压缸14，实现对第一液压缸13和第二液压缸14缩回的控制实现闸门开启，第一液压缸13和第二液压缸14在重力作用下伸出实现闸门关闭。The power unit of the hydraulic control subsystem is driven by a diesel engine 3 to drive a gear pump 2, and the generator 4 provides power support. When the original system 22 loses power, the relay coil 21 will act to close the normally open contact 28 of the relay; or when the original system 22 fails, the signal controller 29 detects the fault and activates the relay coil 21 to close the normally open contact 28 of the relay, thereby quickly and intelligently switching to the emergency operation mode, starting the diesel engine 3, and driving the gear pump 2 to work. The gear pump 2 sucks oil from the oil tank 26 through the oil suction filter 1 and inputs the hydraulic oil into the system. The hydraulic oil first enters the hydraulic control circuit through the third one-way valve 5. The electromagnetic overflow valve 6 is used to maintain a constant pressure in the operating system and prevent overload. The hydraulic oil passes through the first speed regulating valve 10, the second speed regulating valve 17, the first non-return valve 11, the second non-return valve 16, the first two-position two-way electromagnetic ball valve 9, the second two-position two-way electromagnetic ball valve 18, the first electro-hydraulic servo valve 8, the second electro-hydraulic servo valve 19, the first back pressure valve 7 and the second back pressure valve 20, and enters the first hydraulic cylinder 13 and the second hydraulic cylinder 14 respectively through the first two-position three-way electromagnetic ball valve 12 and the second two-position three-way electromagnetic ball valve 15, so as to control the retraction of the first hydraulic cylinder 13 and the second hydraulic cylinder 14 to open the gate, and the first hydraulic cylinder 13 and the second hydraulic cylinder 14 are extended under the action of gravity to close the gate.
需要说明的是，第一两位三通电磁球阀12、第二两位三通电磁球阀15用于在原系统失电或发生故障的情况下快速切换，第一调速阀10和第二调速阀17用于初步控制第一液压缸13和第二液压缸14的运动速度。系统采用伺服同步闭环控制技术，在调速阀调节的基础上，通过液压缸第一位移传感器32和第二位移传感器33的信号控制位移较大的液压缸对应的第一电液伺服阀8或第二液伺服阀19、第一二两位二通电磁球阀9或第二二两位二通电磁球阀18放油微调，实现第一液压缸13与第二液压缸14位移高精度的闭环控制，确保双缸同步运行，提升操作的可靠性。第一背压阀7和第二背压阀20则用于确保液压缸伸出即闸门关闭过程背压的稳定，防止运行过程中的冲击和振动。油箱26配有多个纳污磁环25，磁力吸附了系统工作油液中含有的金属固体颗粒污染物，保证应急系统液压油的清洁，提高电液伺服阀的可靠性，延长操作系统使用寿命。It should be noted that the first two-position three-way electromagnetic ball valve 12 and the second two-position three-way electromagnetic ball valve 15 are used for rapid switching in the event of power failure or failure of the original system, and the first speed regulating valve 10 and the second speed regulating valve 17 are used to preliminarily control the movement speed of the first hydraulic cylinder 13 and the second hydraulic cylinder 14. The system adopts servo synchronous closed-loop control technology. On the basis of speed regulating valve adjustment, the first electro-hydraulic servo valve 8 or the second hydraulic servo valve 19, the first two-position two-way electromagnetic ball valve 9 or the second two-position two-way electromagnetic ball valve 18 corresponding to the hydraulic cylinder with larger displacement are controlled by the signal of the first displacement sensor 32 and the second displacement sensor 33 of the hydraulic cylinder to release oil and fine-tune, so as to realize high-precision closed-loop control of the displacement of the first hydraulic cylinder 13 and the second hydraulic cylinder 14, ensure the synchronous operation of the two cylinders, and improve the reliability of operation. The first back pressure valve 7 and the second back pressure valve 20 are used to ensure the stability of the back pressure during the extension of the hydraulic cylinder, that is, the closing process of the gate, to prevent impact and vibration during operation. The oil tank 26 is equipped with a plurality of dirt-absorbing magnetic rings 25, which magnetically absorb the metal solid particle contaminants contained in the system working oil, thereby ensuring the cleanliness of the emergency system hydraulic oil, improving the reliability of the electro-hydraulic servo valve, and extending the service life of the operating system.
信号控制子系统、状态测控子系统具有智能切换与监控与无人机空中实况监测功能，信号控制器29实时监测原系统22的工作状态。当原系统22失电时，继电器线圈21会动作，使继电器常开触点28闭合；或者当原系统22发生故障时，信号控制器29检测到故障并激活继电器线圈21，使继电器常开触点28闭合，从而快速切换到应急操作模式，并启动应急液压操作系统。同时，信号控制器29将系统状态信息发送至智能手机30，实现远程可视化监控和遥控操作。无人机31用于实时监测泄洪闸的工作状态。无人机31配备高清摄像头和传感器，通过无线信号将监测数据传输至智能手机30，提供实时的现场影像和环境数据，进一步提升系统的安全性和可靠性。The signal control subsystem and the state measurement and control subsystem have the functions of intelligent switching and monitoring and drone aerial real-time monitoring. The signal controller 29 monitors the working status of the original system 22 in real time. When the original system 22 loses power, the relay coil 21 will act to close the normally open contact 28 of the relay; or when the original system 22 fails, the signal controller 29 detects the fault and activates the relay coil 21 to close the normally open contact 28 of the relay, thereby quickly switching to the emergency operation mode and starting the emergency hydraulic operation system. At the same time, the signal controller 29 sends the system status information to the smartphone 30 to achieve remote visual monitoring and remote control operation. The drone 31 is used to monitor the working status of the flood discharge gate in real time. The drone 31 is equipped with high-definition cameras and sensors, which transmit monitoring data to the smartphone 30 through wireless signals, providing real-time on-site images and environmental data, further improving the safety and reliability of the system.
需要说明的是，信号控制器29由蓄电池27供电，实时检测原系统22电源状态以及液压系统状态。通过电压传感器和电流传感器实时监测原系统的电源状态。一旦检测到电源断电或电压、电流异常，信号控制器可以判断原系统出现了电源故障。通过对液压操作系统压力、流量、液压缸位移实时监测，根据压力是否在正常范围内、流量是否骤变出现异常值、位移是否超出预设范围或出现异常波动，信号控制器可以判断液压系统出现故障。It should be noted that the signal controller 29 is powered by the battery 27 and detects the power status of the original system 22 and the hydraulic system status in real time. The power status of the original system is monitored in real time by the voltage sensor and the current sensor. Once a power outage or abnormal voltage or current is detected, the signal controller can determine that a power failure has occurred in the original system. By real-time monitoring of the pressure, flow, and hydraulic cylinder displacement of the hydraulic operating system, the signal controller can determine that a hydraulic system failure has occurred based on whether the pressure is within the normal range, whether the flow suddenly changes to an abnormal value, and whether the displacement exceeds the preset range or has abnormal fluctuations.
另外，智能手机30配备有专用的应用程序，用于实时监控和控制泄洪闸的操作。该应用程序通过无线网络与信号控制器29和无人机31连接，获取实时的视频和传感器数据。信号控制器29负责接收和处理来自智能手机的指令，并将这些指令传输至液压操作系统。监控数据包括液压操作系统压力、阀门状态、液位高度等信息。当需要进行操作时，用户可以通过应用程序发送操作指令，如开启或关闭电磁阀、调节电液伺服阀等。指令通过无线网络传输至信号控制器29，再由信号控制器控制相应的液压元件执行操作。In addition, the smartphone 30 is equipped with a dedicated application for real-time monitoring and control of the operation of the floodgate. The application is connected to the signal controller 29 and the drone 31 via a wireless network to obtain real-time video and sensor data. The signal controller 29 is responsible for receiving and processing instructions from the smartphone and transmitting these instructions to the hydraulic operating system. The monitoring data includes information such as the pressure of the hydraulic operating system, the status of the valve, and the height of the liquid level. When an operation is required, the user can send an operation instruction through the application, such as opening or closing the solenoid valve, adjusting the electro-hydraulic servo valve, etc. The instruction is transmitted to the signal controller 29 via the wireless network, and then the signal controller controls the corresponding hydraulic components to perform the operation.
并且，无人机31配备高清摄像头，用于对泄洪闸及其周边环境进行监测。无人机能够对泄洪闸进行全面检查，拍摄高清图像和视频，并将这些数据实时传输至智能手机30，供远程操作人员查看。通过无人机的实时监测，系统能够获取泄洪闸及其周边环境的详细情况，从而提高了应急操作的智能化和可靠性。In addition, the drone 31 is equipped with a high-definition camera for monitoring the floodgate and its surrounding environment. The drone can conduct a comprehensive inspection of the floodgate, take high-definition images and videos, and transmit these data to the smartphone 30 in real time for the remote operator to view. Through the real-time monitoring of the drone, the system can obtain detailed information about the floodgate and its surrounding environment, thereby improving the intelligence and reliability of emergency operations.
