Description

Technical Field

[0001] This utility model relates to the field of hydrological observation, and in particular to a water level observation device for coal mine subsidence areas. Background Technology

[0002] During the mining of shallow-buried thick coal seams, after the coal seam is mined out, the overlying rock and soil will deform, crack, and collapse, forming a subsidence area. This surface deformation will change the original topography, causing cracks and subsidence depressions on the surface, providing conditions for the collection of surface water.

[0003] As coal seams are mined, the stress balance in the overlying strata is disrupted, resulting in numerous fractures. These fractures gradually develop and interconnect, forming water-conducting fracture zones. The existence of these fracture zones provides a pathway for surface water to enter the mine.

[0004] Before coal seam mining, surface water flows along a certain runoff path. After mining, due to surface deformation and the formation of water-conducting fracture zones, the runoff direction and path of surface water change. Surface water that was not originally easy to accumulate or infiltrate may converge into the subsidence depression and seep into the ground through the water-conducting fracture zones, and then enter the mine.

[0005] Therefore, a water level monitoring device is needed in coal mine subsidence areas to observe surface conditions and water levels. Summary of the Invention

[0034] like Figures 1-3 As shown, the purpose of this utility model is to provide a water level observation device for coal mine subsidence areas, including a support structure 1, a power supply structure 2, a visual processing structure 3, and a detection structure 4.

[0035] The power supply structure 2 is located at the top of the support structure 1;

[0036] Furthermore, the power supply structure 2 includes a connecting frame 21 and a solar panel 22;

[0037] The solar panel 22 is welded to the support plate 11 via the connecting frame 21. The solar panel 22 can be equipped with a battery to store electricity. The power supply structure 2 can provide power to the vision processing structure 3, the charging card slot 121 and the drive motor 5.

[0038] The support structure 1 is T-shaped in general, including support column 12 and support plate 11. The support plate 11 is used to provide support points for image acquisition structure 31, connecting frame 21, cable box 42 and drive motor 5.

[0039] Furthermore, the support column 12 is provided with a charging slot 121, which can charge the imaging processing structure 32.

[0040] Furthermore, the support column 12 is a telescopic structure, which can be buried under the soil layer to fix the overall structure.

[0041] The visual processing structure 3 is located at one end of the support plate 11;

[0042] Furthermore, the visual processing structure 3 includes an image acquisition structure 31 and a processing imaging structure 32;

[0043] The image acquisition structure 31 is set at one end of the support plate 11. The image acquisition structure 31 and the processing imaging structure 32 transmit signals wirelessly to observe surface puddles, rivers, etc.

[0044] The image acquisition structure 31 is powered by the power supply structure 2. The image acquisition structure 31 can be a video acquisition structure such as a camera, and can transmit the acquired image to the processing imaging structure 32 via wireless transmission signal. The processing imaging structure 32 can analyze and process the image and display the analysis results on the display screen.

[0045] The processing imaging structure 32 can be detached and placed in the charging slot 121. The processing imaging structure 32 is equipped with a display screen. During worker inspection, the processing imaging structure 32 can be removed from the charging slot 121 to observe the display screen for inspection. When not in use, the processing imaging structure 32 can be placed in the charging slot 121 for charging.

[0046] The detection structure 4 includes a detection ball 41, a wire release box 42 and a response plate 43, with the wire release box 42 fixedly connected to the upper part of the support plate 11;

[0047] Furthermore, the detection ball 41 is equipped with stabilizing sand 411 inside. The stabilizing sand 411 can keep the detection ball 41 upright on the water surface and prevent it from swaying left and right, thus facilitating the subsequent signal transmission of the rangefinder 413.

[0048] The top of the detection ball 41 is provided with a fixed column 412, and at least two rangefinders 413 are provided on the outer surface of the fixed column 412. The rangefinders 413 may transmit signals to the response plate 43 to measure the distance between the rangefinders 413 and the response plate 43, and send wireless transmission signals to the processing imaging structure 32. The processing imaging structure 32 displays the water level.

[0049] At least two rangefinders 413 are evenly distributed to maintain the stability of the detection ball 41 on the water surface, and to calculate the average value to make the data more accurate.

[0050] Furthermore, a drive motor 5 is provided on the side of the line release box 42. The drive motor 5 is powered by the power supply structure 2 to drive the line release box 42 to release the line, lower the detection ball 41, and then bring it into contact with the water surface. A transmission connection is formed between the line release box 42 and the drive motor 5. A commercially available electric line release structure can be used.

[0051] The wire box 42 is equipped with a wire placement 421, the extended end of which passes through the support plate 11 and connects to the detection ball 41;

[0052] The placement line 421 passes through the inside of the fixing post 412 and is fixed to the detection ball 41.

[0053] The response plate 43 is positioned below the support plate 11. The protruding end of the placement line 421 passes through the center of the support plate 11 and the response plate 43. The response plate 43 is large enough to receive all signals sent from the rangefinder 413. The response plate 43 is located directly above the rangefinder 413.

[0054] During use, the support column 12 is first buried in the soil to maintain the stability of the overall structure. The height of the support column 12 is adjusted so that the image acquisition structure 31 can collect the surface conditions within the target range. The drive motor 5 and the rangefinder 413 are turned on. The drive motor 5 drives the wire laying box 42 to start laying the wire until the detection ball 41 contacts the water surface. The data after the detection ball 41 stabilizes is collected and averaged to obtain the water level. This makes the use more convenient and accurate. The detection ball is equipped with a rangefinder, which can make the data more accurate by averaging. In addition, a vision processing structure is also set up to observe the surface conditions, the number of puddles, etc., so as to monitor the overall situation.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
