技术领域Technical Field
本发明涉及地质勘测装备领域，具体涉及一种柱状沉积物自动切割器及其切割检测方法。The invention relates to the field of geological survey equipment, and in particular to an automatic columnar sediment cutter and a cutting detection method thereof.
背景技术Background Art
现代沉积研究是通过分析沉积物的物质组成、形成过程及平面分布规律等，利用柱状沉积物来重建过去的气候和环境演变。采集分割柱状沉积物是研究沉积物各层次化学成分的重要手段，传统的沉积物切割方式大多是将沉积物样本从沉积物管中推出进行径向切割后分析研究。这种研究方法在切割样品时，由于沉积物通常较软、较粘，推送切割过程，容易发生形变，受力不匀容易错层，使得研究分析不准确。Modern sedimentary research uses columnar sediments to reconstruct past climate and environmental evolution by analyzing the material composition, formation process, and planar distribution of sediments. Collecting and dividing columnar sediments is an important means to study the chemical composition of each layer of sediments. Traditional sediment cutting methods mostly push sediment samples out of sediment tubes for radial cutting and then analyze and study. This research method is prone to deformation during the cutting process because sediments are usually soft and sticky, and uneven force can easily cause misalignment, making the research and analysis inaccurate.
现有技术CN113187411A还提出一种用于沉积取样的半开放式钻杆，其半开放式钻杆可以直接用于取样，取样时，沉积物在进入钻杆过程中，被分隔刀直接分成上下两半。该技术虽然容易将沉积物从钻杆内取出，但过早的切割容易使沉积物样本提前暴露在大气环境中，沉积物样本容易被氧化，菌群容易被污染，导致分析结果不准确。The prior art CN113187411A also proposes a semi-open drill rod for sediment sampling, which can be directly used for sampling. During sampling, the sediment is directly divided into two halves by a dividing knife during the process of entering the drill rod. Although this technology makes it easy to remove the sediment from the drill rod, premature cutting can easily expose the sediment sample to the atmosphere in advance, and the sediment sample is easily oxidized and the bacterial flora is easily contaminated, resulting in inaccurate analysis results.

沉积物管整体呈中空圆柱状，其为沉积物采样钻机的样品管部，用于装填、存储、保护沉积物。沉积物管一端开口，与钻头或密封端盖（图未出）可拆卸连接，沉积物管的该开口端与钻头或密封端盖的可拆卸连接方式为现有技术中常规的连接方式，例如螺纹、卡扣等连接，在沉积物管的开口端设置有用于可拆卸连接的相应结构（图未示出），沉积物管的该开口端内的腔体为沉积物腔；沉积物管的另一端为封闭端，该封闭端部具有中空腔体。The sediment tube is in the shape of a hollow cylinder as a whole. It is the sample tube part of the sediment sampling drill and is used to load, store and protect sediments. One end of the sediment tube is open and is detachably connected to a drill bit or a sealing end cap (not shown in the figure). The detachable connection method between the open end of the sediment tube and the drill bit or the sealing end cap is a conventional connection method in the prior art, such as threaded, snap-fit connection, etc. A corresponding structure for detachable connection is provided at the open end of the sediment tube (not shown in the figure). The cavity in the open end of the sediment tube is a sediment cavity; the other end of the sediment tube is a closed end, and the closed end has a hollow cavity.

如图10所示，当将长条零件22从副管壳体21内抽出一段距离后，副管壳体21的多个圆孔212和长条零件22的多个调节孔223能相互对齐，此时，外部取样和/或检测设备可以通过圆孔212伸入沉积物管内部，进行取样和/或检测。As shown in Figure 10, after the long strip part 22 is pulled out of the auxiliary tube shell 21 for a distance, the multiple circular holes 212 of the auxiliary tube shell 21 and the multiple adjustment holes 223 of the long strip part 22 can be aligned with each other. At this time, the external sampling and/or detection equipment can be extended into the sediment tube through the circular holes 212 for sampling and/or detection.
通过采用上述技术方案，可实现柱状沉积物自动切割和检测，无需外部设备辅助，提高了产品的便携性。本发明沉积物管切割器的切割检测方法包括：By adopting the above technical solution, columnar sediments can be automatically cut and detected without the assistance of external equipment, thereby improving the portability of the product. The cutting and detection method of the sediment pipe cutter of the present invention comprises:
S01. 沉积物管采样收集待测沉积物后，对沉积物管端口密封；S01. After the sediment to be tested is collected by the sediment tube, the port of the sediment tube is sealed;
将主管1和副管2相互拼接后，辅以必要外部增强紧固。在沉积物管开口端装配钻头，进行沉积物采样作业。沉积物管采样收集沉积物作业完成后，拆卸钻头，装配端盖对沉积物管开口端密封。After the main pipe 1 and the auxiliary pipe 2 are spliced together, necessary external reinforcement is provided to tighten them. A drill bit is installed at the open end of the sediment pipe to perform sediment sampling. After the sediment sampling and collection operation of the sediment pipe is completed, the drill bit is removed and the end cap is installed to seal the open end of the sediment pipe.
S02.打开所述多个圆孔212，采集沉积物管中多处待测沉积物样本，进行留样和/或检测；或将检测设备的传感器探头从圆孔212插入沉积物管中，直接检测多个待测沉积物层位数据；S02. Open the plurality of circular holes 212, collect sediment samples to be tested at multiple locations in the sediment tube, retain samples and/or test; or insert the sensor probe of the detection device into the sediment tube from the circular hole 212 to directly detect the data of multiple sediment layers to be tested;
打开多个圆孔212的方法为：将长条零件22从副管壳体21内抽出一段距离，使得副管壳体21的多个圆孔212和长条零件22的多个调节孔223相互对齐。The method for opening the plurality of circular holes 212 is: pulling the long piece 22 out of the auxiliary pipe housing 21 for a distance so that the plurality of circular holes 212 of the auxiliary pipe housing 21 and the plurality of adjustment holes 223 of the long piece 22 are aligned with each other.
将采样装置通过打开的副管2上的多个圆孔212伸入沉积物管中，对待测沉积物进行留样，取出后对留样样本进行检测；The sampling device is inserted into the sediment tube through the multiple circular holes 212 on the opened auxiliary tube 2 to retain samples of the sediment to be tested, and the retained samples are tested after being taken out;
或直接将检测设备的传感器探头通过打开的副管2上的多个圆孔212伸入沉积物管中，对待测沉积物进行检测。Alternatively, the sensor probe of the detection device is directly inserted into the sediment tube through the multiple circular holes 212 on the opened auxiliary tube 2 to detect the sediment to be detected.
检测完毕后，将长条零件22完全推入副管壳体21内，副管壳体21的多个圆孔212和长条零件22的多个调节孔223相互错开，通过长条杆221对实现对圆孔212的密封，沉积物管内的待测沉积物处于密封状态。After the detection is completed, the long strip part 22 is completely pushed into the auxiliary tube housing 21, the multiple circular holes 212 of the auxiliary tube housing 21 and the multiple adjustment holes 223 of the long strip part 22 are staggered with each other, and the circular holes 212 are sealed by the long rods 221, and the sediment to be tested in the sediment tube is in a sealed state.
S03. 在检测前，安装固定切割装置和检测装置。S03. Before testing, install and fix the cutting device and the testing device.
当需要对待测沉积物检测时，卸下沉积物管开口端的端盖；通过工具将沉积物管的主管1和副官2略微分开，以露出传动装置4的两上层链条即可。去除端口部分待测沉积物后，将切割刀具安装在传动机构上层链条的下部。When the sediment to be tested needs to be tested, the end cap of the sediment pipe opening is removed; the main pipe 1 and the adjutant pipe 2 of the sediment pipe are slightly separated by a tool to expose the two upper chains of the transmission device 4. After removing the sediment to be tested at the port, the cutting tool is installed at the lower part of the upper chain of the transmission mechanism.
切割刀具与传动装置的连接方式可以为挂接或卡接，在切割装置两端设置有与链条各节相匹配的结构。优选的，切割装置5与传动机构4的链条的可拆卸连接方式还可以为紧固连接，即在链条的各节上设置有供紧固连接用的孔结构，以方便通过紧固件将切割装置5与传动机构4连接。The connection between the cutting tool and the transmission device can be hooked or clamped, and structures matching the chain sections are provided at both ends of the cutting device. Preferably, the detachable connection between the cutting device 5 and the chain of the transmission mechanism 4 can also be a fastening connection, that is, a hole structure for fastening is provided on each section of the chain to facilitate the connection of the cutting device 5 with the transmission mechanism 4 through fasteners.
如果需要在切割时进行实时检测，可在切割刀具的中间位置附近固定检测装置的检测传感器探头，以使得传感器探头可随刀具延轴线方向移动的同时，实时对各层位沉积物进行扫描检测。If real-time detection is required during cutting, the detection sensor probe of the detection device can be fixed near the middle position of the cutting tool so that the sensor probe can move along the axis of the tool and scan and detect the sediments in each layer in real time.
S04. 切割检测时，传动装置带动切割装置对待测沉积物进行切割，检测装置随切割装置移动并对待测沉积物实时检测，基于检测装置检测速率，控制传动装置传动速率。S04. During the cutting test, the transmission device drives the cutting device to cut the sediment to be tested, and the detection device moves with the cutting device and detects the sediment to be tested in real time. Based on the detection rate of the detection device, the transmission rate of the transmission device is controlled.
在切割时，驱动装置6受控转动，驱动装置6两端的输出轴分布与传动装置4两主动链轮连接，两主动链轮带动两链条同步运转。由于切割刀具固定于链条，切割刀具在链条的带动下进行轴线方向切割。在切割刀具运行至接近沉积物管的另一端时，沉积物管另一端的切割刀具位置传感装置可发送信号，以使得驱动装置6停止运行。当需要多次切割和/或实时检测时，驱动装置6反向旋转，带动切割装置5延轴线方向反向移动切割。随着刀具的切割移动，检测装置可实时对沉积物各层位检测扫描，将检测数据实时发送至控制设备。控制设备可基于检测精度和检测速率控制驱动装置6的转速。During cutting, the drive device 6 rotates in a controlled manner, and the output shafts at both ends of the drive device 6 are connected to the two active sprockets of the transmission device 4, and the two active sprockets drive the two chains to operate synchronously. Since the cutting tool is fixed to the chain, the cutting tool performs axial cutting under the drive of the chain. When the cutting tool runs close to the other end of the sediment tube, the cutting tool position sensor at the other end of the sediment tube can send a signal to stop the drive device 6. When multiple cutting and/or real-time detection are required, the drive device 6 rotates in the opposite direction, driving the cutting device 5 to move in the opposite direction along the axis for cutting. As the cutting tool moves, the detection device can detect and scan each layer of the sediment in real time, and send the detection data to the control device in real time. The control device can control the rotation speed of the drive device 6 based on the detection accuracy and detection rate.
随着链条的移动，切割刀具可沿轴线方向移动，对沉积物进行切割，将沉积物切割为上、下半圆柱体结构。完成切割后，可将沉积物管旋转一定角度，使得上、下半沉积物分离，上半部分沉积物留在副管2内，下半部分沉积物留在主管1内。进而可以对切割完的沉积物进行其他检测。As the chain moves, the cutting tool can move along the axial direction to cut the sediment into upper and lower semi-cylindrical structures. After the cutting is completed, the sediment tube can be rotated at a certain angle to separate the upper and lower sediments, with the upper sediment remaining in the auxiliary tube 2 and the lower sediment remaining in the main tube 1. Then, other tests can be performed on the cut sediment.
S05. 将样本检测数据与对应层位的实时检测数据进行比对，验证实时检测数据有效性。S05. Compare the sample detection data with the real-time detection data of the corresponding layer to verify the validity of the real-time detection data.
根据实验环境和实验要求，切割检测可以在采样完成后立即进行，也可以在回实验室后进行。如果不是实时检测，沉积物形状、组分、菌落、层位等可能会因为运输、氧化、菌群等影响数据准确性；同时，即使是采样后立即检测，在刀具切割时，由于刀具的偏压、沉积物的粘滞等，沉积物也可能发生层位偏移。因此，在完成步骤S04获取实时监测数据后，需要与步骤S02的留样和/或检测数据进行比对；以验证和/或修正切割时实时检测数据的准确性。即将样本检测数据与对应层位的实时检测数据进行比对，验证实时检测数据有效性。如果实时检测数据失真，则该沉积物实时检测数据无效；如果部分数据偏移，则对数据进行修正；如果数据吻合，则数据有效。According to the experimental environment and experimental requirements, the cutting test can be carried out immediately after the sampling is completed, or it can be carried out after returning to the laboratory. If it is not detected in real time, the shape, composition, colony, layer, etc. of the sediment may affect the accuracy of the data due to transportation, oxidation, flora, etc.; at the same time, even if the test is carried out immediately after sampling, the sediment may also shift in layer when the tool is cutting due to the bias of the tool, the viscosity of the sediment, etc. Therefore, after completing step S04 to obtain the real-time monitoring data, it is necessary to compare it with the retained sample and/or detection data of step S02; to verify and/or correct the accuracy of the real-time detection data during cutting. That is, the sample detection data is compared with the real-time detection data of the corresponding layer to verify the validity of the real-time detection data. If the real-time detection data is distorted, the real-time detection data of the sediment is invalid; if part of the data is offset, the data is corrected; if the data matches, the data is valid.
