Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The control mechanism 6 can detect the water level of the gathered water flow, and automatically control the start and stop of the drainage pump 3 according to the water level, so as to complete the drainage work in time. There is no need for workers to manually control the drainage, which is more practical and easier to promote and use. A filtering mechanism 7 is provided at the bottom of the drainage bin 1. When the drainage pump 3 is draining, the gathered water can be filtered by the set filtering mechanism 7 to avoid clogging of the drainage pump 3. When in use, the filtering mechanism 7 can automatically clean the silt adsorbed on the filter bin 701 to ensure the water filtering efficiency of the filter bin 701 and further improve the practicality of the device.

[0023] See also Figure 2The control mechanism 6 includes a connecting rod 601 that vertically penetrates the mounting plate 2 and is slidably connected thereto. The top surface of the mounting plate 2 is provided with a sliding hole for the connecting rod 601 to penetrate and be slidably connected thereto. A hollow floating bag 602 is fixed to the bottom end of the connecting rod 601. A guide rod 603 is fixed to the top surface of the mounting plate 2. A guide plate 604 is slidably connected to the outer peripheral wall of the guide rod 603. A guide hole is provided on the top surface of the guide plate 604 for the guide rod 603 to penetrate and be slidably connected thereto. The top of 603 is fixed to the inner top wall of the drainage chamber 1. When in use, the device is moved to a low-lying area in the coal mine. When water seeps out from the mine, the water gathers in the low-lying area and enters the drainage chamber 1. When the water level gradually rises, it will contact the hollow float 602. The hollow float 602 is pushed upward by the buoyancy of the connecting rod 601. The connecting rod 601 pushes the guide plate 604 to move upward along the guide rod 603. The top of the connecting rod 601 is fixed to the bottom of the guide plate 604. Trigger plates 605 are fixed to the top and bottom surfaces of the guide plate 604, and a start travel switch 606 is fixed to the inner top wall of the drainage bin 1. Further, when the guide plate 604 drives the trigger plate 605 to move upward, when the top trigger plate 605 contacts the start travel switch 606, the start travel switch 606 connects the control circuit and thus enables the drainage pump 3 to work. The drainage pump 3 draws water through the water inlet pipe 4 and transports it to the outside of the mine through the drainage pipe 5. A stop travel switch 607 is fixed to the top surface of the mounting plate 2. The guide plate 604 is located between the start travel switch 606 and the stop travel switch 607. The two trigger plates 605 are respectively opposite to the start travel switch 606 and the stop travel switch 607. When the water level slowly drops, the hollow float 602 loses buoyancy, and the guide plate 604 moves downward under the action of gravity. When the bottom trigger plate 605 contacts the stop travel switch 607, the drainage pump 3 can be automatically stopped, thereby achieving the effect of monitoring the water level and automatically draining water.

[0024] It should be noted that the control circuit of the drainage pump 3 can be implemented through simple programming by technicians in this field. The start limit switch 606 and the stop limit switch 607 mainly play the role of controlling the on and off of the circuit. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0025] See also Figure 2-3In this embodiment, the filter mechanism 7 includes a filter chamber 701 fixed to the bottom surface of the drainage chamber 1. The filter chamber 701 is a cylindrical metal mesh chamber with an open top surface. Before water enters the drainage chamber 1, it will be filtered through the mesh of the filter chamber 701 to remove impurities in the water. A motor 702 is fixed to the top surface of the mounting plate 2. A rotating rod 703 is fixed to the bottom end of the output shaft of the motor 702. Two horizontal rods 704 are fixed to the outer peripheral wall of the rotating rod 703. The opposite ends of the two horizontal rods 704 are fixed with vertical rods. The straight rod 705 starts the motor 702 during drainage, and the motor 702 drives the rotating rod 703 to rotate, and the rotating rod 703 drives the horizontal rod 704 and the vertical rod 705 to revolve around the rotating rod 703. Cleaning brushes 706 are fixed on the opposite sides of the two vertical rods 705 and the bottom surface of the horizontal rod 704. Furthermore, the horizontal rod 704 and the vertical rod 705 drive the cleaning brush 706 to scrub the filter bin 701 to prevent sludge and impurities from clogging the filter mesh of the filter bin 701, thereby ensuring drainage efficiency.

[0026] It should be noted that the motor 702 and the drainage pump 3 are started and stopped synchronously.

[0027] The bottom end of the rotating rod 703 is rotatably connected to the inner bottom wall of the filter chamber 701 , the horizontal rod 704 is connected to the vertical rod 705 in an L shape, and the cleaning brush 706 is in contact with the inner wall of the filter chamber 701 .

[0028] See also Figure 1-2 In this embodiment, an annular plate 8 is fixed on the outer peripheral wall of the drainage bin 1, and four universal wheels 9 are fixed to the bottom surface of the annular plate 8 through a mounting seat. The universal wheels 9 are arranged to facilitate the movement of the device on a flat surface, thereby improving the convenience of transportation. Handles 10 are fixed to the front and back of the drainage bin 1. The handles 10 are arranged to facilitate the lifting of the device for transportation in potholes. An inspection hole 11 is opened on the top surface of the drainage bin 1, and an inspection baffle 12 is fixed to the top surface of the drainage bin 1 by bolts. By removing the inspection baffle 12, the drainage pump 3 and the motor 702 can be inspected and maintained.

[0029] The working principle of the above embodiment is:

[0030] When in use, the device is moved to a low-lying area in a coal mine cave. When water seeps out from the inside of the mine cave, the water gathers in the low-lying area and enters the inside of the drainage bin 1. When the water level gradually rises, it will contact the hollow float 602. The hollow float 602 is pushed upward by the buoyancy of the connecting rod 601. The connecting rod 601 pushes the guide plate 604 to move upward along the guide rod 603. The guide plate 604 drives the trigger plate 605 to move upward. When the top trigger plate 605 contacts the start travel switch 606, the start travel switch 606 connects the control circuit and enables the drainage pump 3 to work. The drainage pump 3 draws water through the water inlet pipe 4 and transports it to the outside of the mine cave through the drainage pipe 5. When the water level slowly drops, the hollow float 602 loses its buoyancy, and the guide plate 604 moves downward under the action of gravity. When the bottom trigger plate 605 contacts the stop travel switch 607, the drainage pump 3 can be automatically stopped, thereby achieving the effect of monitoring the water level and automatically draining water.

[0031] Before water enters the drainage bin 1, it will be filtered through the mesh of the filter bin 701 to remove impurities in the water. When draining water, the motor 702 is started, and the motor 702 drives the rotating rod 703 to rotate. The rotating rod 703 drives the horizontal rod 704 and the vertical rod 705 to revolve around the rotating rod 703. Furthermore, the horizontal rod 704 and the vertical rod 705 drive the cleaning brush 706 to scrub the filter bin 701 to prevent sludge and impurities from clogging the filter mesh of the filter bin 701, thereby ensuring drainage efficiency.
