一种保护水坝测压管的仪表箱An instrument box for protecting piezometric tubes of dams

技术领域technical field

本发明涉及水坝测压管的保护装置，特别是一保护水坝测压管的仪表箱。The invention relates to a protection device for a dam piezometric tube, in particular to an instrument box for protecting the dam piezometer tube.

背景技术Background technique

为了保证水库大坝的安全，多年来，人们采取了大量的工程手段，监测大坝的运行安全状况。其中，测压管是渗流监测中最重要的监测装置，其建造过程复杂，保护难度较大，运行中常被外部落物堵塞而报费，严重影响大坝的安全运行监测。In order to ensure the safety of the reservoir dam, people have adopted a large number of engineering methods to monitor the operation safety of the dam over the years. Among them, the piezometric tube is the most important monitoring device in seepage monitoring. Its construction process is complicated and its protection is difficult. During operation, it is often blocked by external falling objects, which seriously affects the safe operation monitoring of the dam.

目前，现有的测压管保护装置是用自制的铁帽或砖石混凝土砌筑体加铁盖设置在测压管口进行防护，这些防护方法建造过程复杂、施工工程量大、防护等级低、容易被人撬开破坏。此外，随着近年来计算机自动化技术的发展，水库大坝安全监测亟需实现自动化。由于水库所在地周边条件的限制，其山区自然环境及人为破坏等，使管口防护已成为水库大坝安全运行自动化监测设备无法在现场(特别是大坝上)安装的一大棘手问题。现有的测压管保护装置更无法适应自动化监测设备特别是二次仪表的现场安装。At present, the existing protection devices for piezometric tubes are protected by self-made iron caps or masonry concrete masonry and iron caps on the piezometric tube openings. These protection methods are complex in construction process, large in construction engineering, and low in protection level , It is easy to be pried open and damaged. In addition, with the development of computer automation technology in recent years, the safety monitoring of reservoirs and dams urgently needs to be automated. Due to the limitation of the surrounding conditions of the reservoir location, its mountainous natural environment and man-made damage, nozzle protection has become a thorny issue that cannot be installed on-site (especially on the dam) with automatic monitoring equipment for safe operation of reservoir dams. The existing protection devices for piezometric tubes cannot adapt to the on-site installation of automatic monitoring equipment, especially secondary instruments.

Block 4 and hinged lower block 6 jointly control the opening position of the box cover 8, preventing the on-site staff from throwing and throwing the type flipping cover to cause the impact of the dam body and the box body 1. One end of the case cover 8 is hinged to the casing 1 through a concealed hinge 9, and the other end is a free end, which can be opened or closed along the concealed hinge 9. The concealed hinge 9 is located at the overlapping part of the case cover 8 and the casing 1, which can prevent people from prying from the hinge. On the casing 1 below case cover 8 free ends, be provided with enclosure type tamper-resistant lock 7, and it cooperates with case cover 8, can prevent lockset from being picked. The front and rear surfaces of the box body 1 are respectively equipped with anair inlet plate 2 and an air outlet plate 3, and a plurality of air holes 5 are opened on the box body 1 under theair inlet plate 2 and the air outlet plate 3 to realize smooth air flow regulation . The bottom surface of the box body 1 is provided with the piezometric pipe inlet 10, the collecting and draining hole 13, and the wire inlet hole 14 according to the position, size and distribution of the cables of the piezometric pipe on the dam site. The inner wall of the box body 1 is provided with a plurality ofcable clamps 11, which are used to fix the cables passing into the box from the dam. The bottom surface of the box body 1 is provided with a plurality of box-embedded anchor holes 12, through which the anchor bolts penetrate into the box for fixing, effectively preventing the instrument box from being dismantled from the outside.

安装本发明时，在需要实施保护的测压管管口建筑偏心结构的混凝土基台，台面中心设置集流坑和与其相连的引槽，仪表箱内一旦有积水可经箱底的集流排水孔13与基台配合排出箱外，于台面汇流后由引槽集中排向离测压管较远的一端，使雨水或冷凝水离开测压管管壁，防止水流渗进管内影响测量精度。然后将测压管经测压管进口10插入箱体1内，并将箱体1焊接在测压管上，保持箱体1及箱内设备的良好接地。再将来自水坝不同方向的电缆线经进线孔14穿入箱体1内，并由箱内电缆夹扣固定，防止电缆线沿水坝坡敷设后高端电缆滑脱。需要安装自动化仪表或进行二次仪表安装时，可打开箱盖8进行安装即可，安装完毕后再关闭箱盖8、上锁。When installing the present invention, build an eccentric concrete abutment with an eccentric structure at the mouth of the piezo tube that needs to be protected, and set a sump pit and a guide groove connected to it in the center of the table top. Once there is accumulated water in the instrument box, it can be drained through the collection at the bottom Hole 13 cooperates with the abutment to discharge out of the box, and after converging on the table, it is discharged to the end far away from the piezometric tube by the guide groove, so that rainwater or condensed water leaves the wall of the piezo tube to prevent water from seeping into the tube and affecting the measurement accuracy. Then insert the pressure measuring tube into the box body 1 through the pressure measuring tube inlet 10, and weld the box body 1 on the pressure measuring tube to keep the good grounding of the box body 1 and the equipment in the box. Then the cables from different directions of the dam are penetrated in the box body 1 through the inlet hole 14, and are fixed by the cable clips in the box to prevent the high-end cables from slipping off after the cables are laid along the slope of the dam. When automation instrument needs to be installed or secondary instrument is installed, case cover 8 can be opened and installed, and case cover 8 is closed and locked after installation.

本发明采用半埋式安装与长短油度的漆料配合以解决温差、日晒和腐蚀带来的负面效应，组合式通气孔板可进一步调节箱内温度、湿度并保证相对压力的测量。坡式箱盖的设计可使秋季到初冬期间箱盖内的凝结水流至箱外，悬置式仪表架可使二次仪表免受凝结水的影响。The present invention adopts semi-buried installation and long and short oily paints to solve the negative effects caused by temperature difference, sunlight and corrosion. The combined ventilation hole plate can further adjust the temperature and humidity in the box and ensure the measurement of relative pressure. The design of the sloping box cover allows the condensed water in the box cover to flow out of the box from autumn to early winter, and the suspended instrument frame can protect the secondary instrument from the influence of condensed water.
