Description

Technical Field

[0001] The utility model relates to the technical field of hydrogeological exploration, in particular to a stratified water-stopping device for coalfield hydrogeological exploration. Background Art

[0002] The stratified water-stopping device for coalfield hydrogeological exploration refers to a technical solution that uses specific measures and devices to control and isolate water at different strata in order to effectively prevent water gushing problems under hydrogeological conditions during coalfield hydrogeological exploration and mine mining.

[0003] The publication number is CN217841603U. The Chinese patent discloses a stratified water-stopping device for hydrogeological exploration in coalfields, which includes a main component, an adjusting component and a fixing component. The main component includes a water-stop plate and a water-stop strip; the outer wall of the water-stop plate is fixedly connected with the water-stop strip; the fixing rod is inserted into the rock layer by rotating the first bevel gear, and the fixing effect is relatively good, and it is not easy to tilt, thereby reducing the possibility of water seepage; the water-stop plate and the water-stop strip cooperate to stop water, and the water-stop strip expands after absorbing water to fill the gap. At the same time, the water-stop strip is not easy to corrode and can stop water for a long time.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, firstly, water-swelling rubber is used as the material of the waterstop. Although it can fill the gaps around the waterstop plate after absorbing water, the cost of this expansion material is relatively high, and the cost of subsequent maintenance and replacement is also relatively large. Secondly, the device can only perform stratified sampling individually, and it is not convenient to sample in different water layers at the same time. This leads to a decrease in work efficiency, because the sampling of each water layer needs to be operated separately, and the sampling of multiple water layers cannot be completed at one time. These problems affect our convenience and efficiency in actual use. Therefore, it is necessary to provide a stratified waterstop device for coalfield hydrogeological exploration to solve the above technical problems. Utility Model Content

By extruding the annular sealing rubber belt, the device can achieve an effective sealing effect, and the cost of this annular sealing rubber belt is relatively low, which is more economical. In addition, the device is designed with multiple sets of first waterstop plates and second waterstop plates, which can separate multiple water layers at the same time, thereby improving the efficiency and flexibility of the device.

[0032] The outer side of the bottom of the annular extrusion plate 10 abuts against the inner side of the upper surface of the annular sealing rubber belt 5 , and limiting rods 9 are fixedly installed on both sides of the pipeline 2 between the first water stop plate 3 and the second water stop plate 4 , and a driving mechanism is arranged inside the fixed box 1 .

[0033] A sampling tube 7 is fixedly installed on the outer wall of the pipeline 2 below the second water stop plate 4, and the sampling tube 7 is connected to the interior of the pipeline 2. An electric valve 8 is provided on the sampling tube 7. The bottom end of the pipeline 2 is a sealing structure, which is convenient for pumping water and sampling from different water layers.

[0034] In one of the embodiments, the driving mechanism includes a motor 11, and the motor 11 is fixedly installed on one side of the fixed box 1. A worm 12 is fixedly installed on the driving end of the motor 11. A worm wheel 13 is fixedly installed on the top outer wall of the two adjusting screw rods 6, and the worm wheel 13 is meshed with the worm 12. Under the drive of one motor 11, the synchronous rotation of the two adjusting screw rods 6 is achieved, which reduces the operating cost of the device and improves the practicability of the device.

[0035] In one of the preferred embodiments, a sliding hole matched with the limiting rod 9 is opened on the outer side of the top of the annular extrusion plate 10, and the annular extrusion plate 10 is slidably connected with the limiting rod 9 through the sliding hole opened on the outer side of the top.

In addition, the device is designed with multiple sets of first water stop plates 3 and second water stop plates 4, which can separate multiple water layers at the same time, thereby improving the use efficiency and flexibility of the device.

[0039] When it is necessary to sample the water in each water layer, the top of the pipe 2 can be connected to the pump body. Then the electric valve 8 on each sampling tube 7 is opened in sequence, so that the water sampling of different water layers can be completed. This operation simplifies the process of stratified sampling and improves the efficiency of use. In this way, water samples of each water layer can be obtained quickly and effectively, which provides convenience for subsequent analysis and processing.
