Description

Technical Field

[0001] The utility model belongs to the technical field of water accumulation detection in goaf areas, and in particular relates to a water accumulation detection device in goaf areas of coal mines. Background Art

[0002] Coal mine goaf refers to the hollow space or cavity left after underground coal or coal gangue is mined during coal mining operations. Due to factors such as abundant rainfall in some coal mines, abundant groundwater resources in the area, or domestic water discharge from nearby residents, water may flow back to the low-lying areas of the coal mine goaf to form water accumulation, which seriously threatens the safe production of the mine. We need to detect and deal with water accumulation in the coal mine goaf.

[0003] In the prior art, transient electromagnetic instruments are widely used due to their low cost, high lateral resolution, and optimal coupling with the detection target. However, when in use, the water detection rope is usually laid to the area to be detected, and workers use the transient electromagnetic instrument for digital detection, which not only has low work efficiency but also increases the labor intensity of workers; and because the coal mine goaf is large, the water detection rope required is long, which is not only inconvenient to carry, but also cumbersome to store and lay.

[0025] Example 1

[0026] refer to Figure 1-5 , a coal mine goaf water detection device, comprising:

[0027] The workbench 1 and the box body 2 below the workbench 1, the box body 2 is respectively provided with a collecting mechanism and a moving mechanism on the upper and lower parts, the collecting mechanism includes a first rotating rod 3, a collecting rod 4 and a connecting rod 29, the connecting rod 29 is fixedly connected to the box body 2, the collecting rod 4 and the connecting rod 29 are rotatably connected to the box body 2, a driving block 5 is sleeved on the first rotating rod 3, a first slider 28 sleeved on the connecting rod 29 is provided above the driving block 5, the driving block 5 is connected to the collecting rod 4 through a sleeve 6, the moving mechanism is symmetrically arranged on both sides of the box body 2, the moving mechanism includes a second rotating rod 7 and a moving plate 8, the second rotating rod 7 is sleeved with a second slider 9, and the second slider 9 is connected to the moving plate 8 through a connecting block 10.

[0028] In this embodiment, the workbench 1 is tilted and connected to the box 2 through a bracket 11. The workbench 1 is tilted to facilitate workers to operate the detector 13 and check data. A limit plate 12 is provided at the lower part of the workbench 1. The detector 13 is provided on the workbench 1 and abuts against the limit plate 12. The limit plate 12 can limit the position of the detector 13 to prevent the detector 13 from sliding downward along the inclined surface on the workbench 1 and causing the detector 13 to be broken.

[0029] In this embodiment, the first rotating rod 3 is provided with an external thread, and the driving block 5 is provided with an internal thread matching the external thread of the first rotating rod 3. The driving block 5 is connected to the first slider 28, and the first slider 28 moves along the connecting rod 29 to guide the driving block 5; a first gear 14 is provided at one end of the first rotating rod 3, and a first support 15 is provided at the other end. A first motor 16 is provided on one side of the first rotating rod 3. The first motor 16 drives the first rotating rod 3 and the first gear 14 to rotate. The driving block 5 can move in a straight line along the thread on the first rotating rod 3. The first support 15 provides support for the first rotating rod 3 and also supports its rotation.

[0030] In this embodiment, a second gear 17 is provided directly below the first gear 14, and the second gear 17 is fixedly connected to the collecting rod 4. Both ends of the collecting rod 4 are provided with second supports 18 rotatably connected thereto. A sleeve 6 is sleeved on the collecting rod 4, and the sleeve 6 is connected to the driving block 5. A collecting tube 19 is provided on one side of the sleeve 6. The first gear 14 and the second gear 17 are meshed with each other to transmit power to the collecting rod 4, so that the collecting rod 4 rotates to realize the collection of the water detection electric rope cloth.

The connecting rods 24 are hinged to the second sliding blocks 9 and the connecting blocks 10, and a movable plate 8 is provided under the connecting block 10. The second motor 22 rotates, driving the second rotating rod 7 to rotate, so that the second sliding block 9 moves in the opposite direction on the second rotating rod 7, causing the connecting rod 24 to rotate relatively, and the connecting rod 24 will bring the connecting block 10 and the movable plate 8 up. The arrangement is ingenious and the operation is simple.

[0033] In this embodiment, a first support rod 31 is provided below the movable plate 8, a cavity 30 is provided inside the lower side of the first support rod 31, a second support rod 25 is provided at the lower part of the first support rod 31, the upper part of the second support rod 25 is inserted into the cavity 30, a spring 26 is provided on the second support rod 25, and a roller 27 is provided below the second support rod 25. When there is no need to move the box body 2, the movable plate 8 rises to drive the roller 27 to rise, so that the roller 27 leaves the ground and the box body 2 contacts the ground, providing support for the device and making it work more reliably; when it is necessary to move the box body 2, the movable plate 8 drives the roller 27 to descend while the second support rod 25 can rise or descend along the cavity 30. Combined with the spring 26, the vibration caused by the uneven ground can be reduced.
