Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically a drainage device for underground coal mines. Background Technology

[0002] The core purpose of underground drainage devices in coal mines is to discharge underground water (including groundwater, seepage water from rock strata, and production wastewater) in a timely and efficient manner, prevent excessive water accumulation underground, avoid flooding of mining faces, roadways, and equipment, and ensure a normal production and operation environment in the mine. Utility model patent CN214196394U discloses a drainage device for underground coal mines, including casters, a filter plate rotatably connected to the inner side of a filter box, a first spring fixedly connected to the bottom of the inner side of the filter box, a slider slidably connected to the right side of the inner side of the filter box, a second spring fixedly connected to the bottom of the slider, a garbage bin fixedly connected to the left side of the filter box, and a sliding plate slidably connected to the inner side of a mounting frame. This utility model filters coal sludge and slag from wastewater through the filter plate, preventing pump blockage and damage, and extending pump lifespan. The pressure of the wastewater on the filter plate and the elastic force of the second and first springs cause the coal sludge and slag on the filter plate to enter the garbage bin, improving the device's efficiency. Pulling the sliding rod causes the locking block to squeeze the third spring, thereby rotating the sealing plate and removing the garbage bin for easy cleaning.

[0003] However, the device has the following shortcomings: when the device reaches the designated position, the wheels are not easily restrained, making the device prone to instability at the designated position; and the device lacks a sealing mechanism, so the connection between the second water suction pipe and the connecting pipe cannot be sealed, resulting in water leakage at the connection between the second water suction pipe and the connecting pipe. Therefore, improvements are needed. Utility Model Content

Contacting the connecting pipe 11, the support sleeve 12 is equipped with a sealing mechanism 13. By starting the motor 3, the motor 3 drives the screw 4 to move in a threaded motion with the connecting frame 6. The moving connecting frame 6 drives the limit block 9 and other components to move. The limit block 9 moves and contacts the wheel 2, limiting the wheel 2 and ensuring that the device is placed stably in the designated position.

[0022] Please refer to Figures 5 and 6. The sealing mechanism 13 includes a connecting rod 131. The connecting rod 131 is in contact with the inside of the support sleeve 12. A handle 132 is fixedly connected to the connecting rod 131. An annular sleeve 133 is in contact with the inside of the support sleeve 12. The annular sleeve 133 is fixedly connected to the connecting rod 131. A slot 134 is provided inside the annular sleeve 133. A block 135 is slidably connected inside the slot 134.

[0023] Please refer to Figures 5 and 6. An elastic rod 138 is provided inside the support sleeve 12. One end of the elastic rod 138 is fixedly connected to the locking block 135, and the other end is fixedly connected to the support sleeve 12. By designing the elastic rod 138, the locking block 135 has an elastic force, allowing the support sleeve 12 and the locking block 135 to slide together. A sealing sleeve 139 is fixedly connected to the outer side of the annular sleeve 133.

[0024] The specific implementation process of this utility model is as follows: When the device reaches the designated position, the motor 3 is started, the motor 3 drives the screw 4 to rotate, the screw 4 rotates and drives the rotating block 5 to rotate, the screw 4 rotates and causes the connecting frame 6 to have a threaded movement, which in turn causes the connecting frame 6 to have a relative displacement. The connecting frame 6 moves downward and drives the connecting sleeve 8 to move downward, the connecting sleeve 8 moves downward and drives the limiting block 9 to move downward, the limiting block 9 moves downward and contacts the wheel 2, so that the wheel 2 is limited and the device is placed stably in the designated position.

[0025] When the connection between the second water-drawing pipe 10 and the connecting pipe 11 on the device needs to be sealed, the moving handle 132 moves towards the support sleeve 12. The movement of the handle 132 drives the connecting rod 131 to move, which in turn drives the annular sleeve 133 to move. The movement of the annular sleeve 133 drives the slot 134 and the sealing sleeve 139 to move. The sealing sleeve 139 moves and contacts the second water-drawing pipe 10, which in turn causes the elastic force of the elastic rod 138 to push the locking block 135 to move. The movement of the locking block 135 drives the sliding groove 136 to move, and the locking block 135 moves into the slot 134, thus limiting the sealing sleeve 139 and other components, sealing the connection between the second water-drawing pipe 10 and the connecting pipe 11, and preventing water leakage at the connection between the second water-drawing pipe 10 and the connecting pipe 11 on the device.
