[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an auxiliary drainage device for water prevention and control in coal mine construction, comprising: a drainage pool 1, which consists of an inlet pipe, a drain pipe, a water pump, and a dismantling chamber. The inlet pipe and the drain pipe are respectively installed on both sides of the drainage pool 1 to transport coal mine water into the interior of the drainage pool 1 and then discharge the filtered water. The water pump provides power for the water flow. The dismantling chamber is located in the middle of the drainage pool 1. When the outer shell 21 is stored in the dismantling chamber, it is convenient to remove the filter screen 22 inside the outer shell 21.

[0039] like Figure 2 - Figure 3 As shown, the filter assembly 2 is placed inside the drainage tank 1. The filter assembly 2 includes a rotating shaft 23 rotatably connected to the top of the inner side of the drainage tank 1 and a housing 21 disposed on both sides of the rotating shaft 23. The housing 21 is slidably connected to the drainage tank 1. A filter screen 22 is disposed inside the housing 21. A roller 26 is rotatably connected to the side of the drainage tank 1 near the rotating shaft 23. A gear 28 is disposed on the end of the rotating shaft 23 near the roller 26. A locking groove 29 is opened on the end of the roller 26 near the gear 28. The roller 26 is locked to the rotating shaft 23 through the gear 28 and the locking groove 29.

[0040] like Figure 2 - Figure 3As shown, the adjusting component 3 is located on one side of the filter component 2 and is used to control the rotating shaft 23 to lift the outer shells 21 on both sides. The adjusting component 3 includes a knob 31 located at one end of the rotating shaft 23. A slider 32 is fixedly connected to the end of the rotating shaft 23 near the knob 31. The knob 31 is slidably connected to the rotating shaft 23 through the slider 32. The knob 31 is threadedly connected to the drainage pool 1. By opening a groove on the inner side of the outer shell 21, it is easy to place the filter screen 22 inside the outer shell 21. When the filter screen 22 is placed at the bottom of the drainage pool 1, the inner wall of the drainage pool 1 seals the outer shell 21, which facilitates the filter screen 22 to filter the coal slag inside the mine water. Two filter screens 22 are installed inside the drainage pool 1. The two filter screens 22 are used alternately inside the drainage pool 1. When one filter screen 22 is filtered by the coal slag, it is used to filter the coal slag. When clogged, the clogged filter screen 22 is retracted and replaced with a new one. Simultaneously, another filter screen 22 continues to filter the coal slag in the mine water, resolving the issue of filter screen 22 clogging requiring machine downtime for maintenance. This allows the auxiliary drainage device to operate continuously, improving its drainage efficiency. By creating an inner groove on the knob 31 that matches the slider 32, rotating the knob 31 causes the rotating shaft 23 to move inside the drainage pool 1. When the rotating shaft 23 moves closer to the knob 31, it drives the gear 28 to engage with the middle drum 26. When the rotating shaft 23 moves away from the knob 31, it drives the gear 28 to engage with the drums 26 at both ends. Thus, by adjusting the position of the rotating shaft 23 inside the drainage pool 1 via the knob 31, different drums 26 are controlled. The drums 26 then move the corresponding outer casing 21 on the drainage pool 1, achieving centralized control of the two filter screens 22.

[0041] Furthermore, such as Figure 2 - Figure 3 As shown: A steel wire rope 25 is provided between the drum 26 and the outer shell 21. One end of the steel wire rope 25 is fixedly connected to the outer shell 21, and the other end of the steel wire rope 25 away from the outer shell 21 is fixedly connected to the drum 26. By installing the steel wire rope 25 between the outer shell 21 and the drum 26, when the rotating shaft 23 drives the drum 26 to rotate, the drum 26 will wind the corresponding steel wire rope 25 around itself, which makes it easier for the steel wire rope 25 to lift the corresponding filter screen 22.

[0042] Furthermore, such as Figure 2 - Figure 3As shown: A guide roller 24 is rotatably connected to the side of the drainage pool 1 near the rotating shaft 23. The guide roller 24 is connected to the wire rope 25 for transmission. By installing a bracket on the drainage pool 1, the bracket is used to support the guide roller 24 and the drum 26. When the drum 26 drives the wire rope 25 to move, the guide roller 24 supports the wire rope 25, so that the end of the wire rope 25 near the outer shell 21 is perpendicular to the outer shell 21, preventing the outer shell 21 from being displaced when it moves.

[0043] Furthermore, the side of the gear 28 near the drum 26 is a flat-headed cone. By setting one side of the gear 28 as an inclined structure, the diameter of the side of the gear 28 near the locking groove 29 is smaller than the diameter of the locking groove 29. When the gear 28 moves into the locking groove 29, it is easy to lock the gear 28 into the locking groove 29, preventing the gear 28 and the locking groove 29 from jamming each other, and preventing the rotating shaft 23 from being unable to drive the drum 26 to rotate through the gear 28.

[0044] To solve the problem of mismatched angles between gear 28 and locking groove 29, resulting in failure to engage, such as... Figure 2 - Figure 3 As shown: A limiting block 6 is fixedly connected to one end of the rotating shaft 23 near the gear 28. A limiting groove 7 is formed on one side of the gear 28 near the limiting block 6. The gear 28 is engaged with the rotating shaft 23 through the limiting block 6 and the limiting groove 7. By forming the limiting groove 7 on the gear 28, when the angle between the gear 28 on one side and the engaging groove 29 is not matched and they cannot be engaged, the gear 28 can be offset on the rotating shaft 23 through the limiting block 6 and the limiting groove 7, leaving a certain adjustment space for the gear 28, which is beneficial to the adaptation of the gear 28 and the engaging groove 29.

[0045] Furthermore, such as Figure 2 - Figure 3 As shown: A motor 27 is fixedly connected to the side of the drainage tank 1 near the rotating shaft 23. A snap-fit ​​cylinder 33 is fixedly connected to the output end of the motor 27. A snap-fit ​​post 34 is fixedly connected to the side of the rotating shaft 23 near the snap-fit ​​cylinder 33. The rotating shaft 23 is snapped to the motor 27 through the snap-fit ​​cylinder 33 and the snap-fit ​​post 34. By inserting the rotating shaft 23 into the inside of the snap-fit ​​cylinder 33, the rotating shaft 23 can be adjusted to the position on the drainage tank 1 with the knob 31. The snap-fit ​​post 34 installed on the slider 32 is snapped to the snap-fit ​​cylinder 33, so that the motor 27 drives the rotating shaft 23 to rotate through the snap-fit ​​post 34, thereby allowing the slider 32 to adjust its position inside the drainage tank 1 while maintaining linkage with the motor 27.

[0046] To address the problem of mine water leaking from the opening after the outer casing 21 is separated from the interior of the drainage pool 1, such as... Figure 2 - Figure 3As shown: A base plate 4 is fixedly connected to the bottom of the drainage pool 1. A sealing gasket 5 is slidably connected to the side of the base plate 4 near the outer shell 21. A spring 8 is fixedly connected between the base plate 4 and the sealing gasket 5. By installing the spring 8 between the sealing gasket 5 and the base plate 4, when the filter screen 22 is at the bottom of the drainage pool 1, the outer shell 21 compresses the sealing gasket 5 inside the base plate 4. When the outer shell 21 separates from the bottom of the drainage pool 1, the compressed spring 8 bounces the sealing gasket 5 up, sealing the opening on the drainage pool 1 and preventing the leakage of coal mine water.

[0047] Working principle: such as Figure 1 - Figure 5 As shown, the water is fed into the drainage pool 1 through the inlet. The filter screen 22 on the side near the inlet of the drainage pool 1 filters the coal slag in the coal mine water. When the filter screen 22 on one side becomes clogged, it needs to be removed. At this time, the motor 27 is started first. The motor 27 drives the rotating shaft 23 to rotate through the clamping cylinder 33 and the clamping post 34. The rotating shaft 23 drives the drums 26 on both sides to rotate. The drums 26 lower the steel wire rope 25 wound on itself. The steel wire rope 25 drives the outer shell 21 on the other side to move downward through the guide roller 24, so that the filter screen 22 on the other side moves to the bottom of the drainage pool 1 to filter the coal slag.

[0048] Then, rotate knob 31. Knob 31 drives shaft 23 to move to one side of knob 31 via slider 32, so that gear 28 in the middle of shaft 23 engages with drum 26. Gears 28 at both ends of shaft 23 are separated from drums 26 at both ends through engagement grooves 29. Start motor 27. Motor 27 drives the outer casing 21 on one side to the top of drain pool 1 via the middle drum 26 and wire rope 25. Then, the clogged filter screen 22 is removed and replaced. At the same time, when the outer casing 21 separates from the bottom of drain pool 1, the compressed spring 8 pops up the sealing gasket 5 to seal the opening at the bottom of drain pool 1.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
