[0028] The drain pipe 30 is spirally arranged, and the cross section of the drain pipe 30 is rectangular. The lower end of the drain pipe 30 is arranged downward and higher than the lower end surface of the ring member 20. The upper end of the drain pipe 30 has a straight pipe portion 31, and the straight pipe portion 31 is connected to the water inlet end of the water pump through an extension pipe. A filter plate 32 is installed in the straight pipe portion 31. The filter plate 32 is inclined. The filter plate 32 is close to the inner side of the spiral of the drain pipe 30, and the filter plate 32 is close to the ring member 20. A shell connected to the straight pipe portion 31 is arranged on the side of the straight pipe portion 31 away from the ring member 20. The housing 33 has a collecting member rotatably mounted in it. The collecting member is close to the spiral outer side of the drain pipe 30 and is located on the side of the filter plate 32 away from the annular member 20. A through hole 331 is provided at the bottom of the housing 33. The through hole 331 is connected to the inner side of the annular member 20 through a connecting pipe 332. An impeller 35 is rotatably mounted in the straight pipe portion 31. When the drain pipe 30 is pumping water, water in the drain pipe 30 can first pass through the filter plate 32 and then pass through the impeller 35, and then enter the water inlet end of the water pump.

[0029] The housing 33 has a cylindrical cavity for installing a collecting member. The collecting member includes a shaft 341 rotatably connected to the housing 33. A plurality of partitions 342 are arranged at intervals along the circumference of the shaft 341. The end of the partition 342 away from the shaft 341 can fit with the inner wall of the housing 33. A storage cavity is formed between two adjacent partitions 342 and the inner wall of the housing 33. The upper end of the shaft 341 extends upwardly out of a straight tube portion 31.

[0030] Taking one of the baffles 21 as an example, one end of the baffle 21 has a matching shaft 211 that is rotatably matched with the ring member 20, and a fifth gear 212 is coaxially fixedly arranged on the outer periphery of the matching shaft 211. A rack 41 and a vertical rod 42 are arranged on the outer wall of the airbag 40 in the vertical direction. The bottom end of the vertical rod 42 is lower than the rack 41. A limit member is slidably installed in the ring member 20 in the horizontal direction. The limit member is connected to the ring member 20 through a second elastic member. The second elastic member is specifically a second spring. The limit member includes a fixed phase. The guide block 23 has an inclined guide surface 231 on the side facing the insertion rod 22, a slot 213 matching the insertion rod 22 is provided on the baffle 21, two slide grooves for the sliding of the airbag 40 are provided on the inner wall of the ring 20, the outer wall of the airbag 40 has a slider 43 matching the slide groove, the rack 41 and the vertical rod 42 are fixedly connected to the slider 43 respectively, and a retaining ring 24 for limiting the downward movement of the airbag 40 is fixedly provided on the inner wall of the ring 20.

[0031] Specific working principle: Reference Figure 1-Figure 10 , put the whole device into the water in the mine. At first, due to the high liquid level, the whole device is in a floating state under the action of the airbag 40. At this time, the slider 43 is located at the top of the slide and stops with the annular member 20. There is a distance between the lower end of the drainage pipe 30 and the bottom of the water. The two plug rods 22 are respectively inserted into the two slots 213 so that the two baffles 21 are in a state of closing the bottom of the annular member 20, and the lower end surfaces of the two baffles 21 are flush with the bottom surface of the annular member 20. Next, start the water pump, the water in the mine can be pumped out, and no stones will enter the drainage pipe 30 during this process. As the liquid level in the mine continues to decrease, when the annular member 20 contacts the bottom of the water, the two baffles 21 also contact the bottom of the water. At this time, as the water pump The drain pipe 30 is spirally arranged, and the stones are affected by centrifugal force when they move upward in the drain pipe 30, so that the stones move upward along the spiral outer side of the drain pipe 30. When the stones move to the straight pipe portion 31, the stones can enter the storage cavity under the action of the water flow and the filter plate 32. During this process, the collecting member can rotate slowly, so that the stones can move with the collecting member into the through hole 331, and then enter the inner ring side of the annular member 20 through the connecting pipe 332, and fall on the upper end of the baffle 21, wherein the water in the storage cavity can be discharged into the mine again through the second hole and the third hole, thereby avoiding the blockage of the filter plate 32 and extending the service life of the filter plate 32.

[0032] After the pumping work is completed, the device is lifted up as a whole and leaves the water surface. During this process, the airbag 40 begins to move downward, and the vertical rod 42 first stops with the guide surface 231 to make the limiter move as a whole in the direction away from the slot 213, so that the insertion rod 22 is released from the lock on the baffle 21. As the device continues to move upward, the airbag 40 continues to descend until it stops with the baffle ring 24. During this process, the rack 41 begins to mesh with the fifth gear 212 and drives the baffle 21 to rotate downward, so that the stones located in the ring 20 will be discharged downward. When the device is placed in a position with a higher liquid level in the mine again, the airbag 40 moves upward along the slide groove under the action of buoyancy. During this process, the rack 41 meshes with the fifth gear 212 and drives the baffle 21 to rotate upward until the two baffles 21 are reset again to the state of closing the bottom of the ring 20. At this time, the insertion rod 22 enters the slot 213 again to lock the baffle 21, and then repeat the above steps.

[0033] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
