[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] like Figure 1-Figure 7 As shown, the utility model proposes an automatic drainage device for a coal mine water tank, comprising a drainage device 1, a floating trigger device 2, and a water tank 3. The drainage device 1 includes a drainage pump 4 and a filter barrel 6. One end of the drainage pump 4 is connected to a pumping pipe 10, which extends to the inner bottom of the filter barrel 6 and is used to extract water from the filter barrel 6 and discharge the water through the drainage pump 4. The filter barrel 6 is arranged in the water tank 3 and is used to filter impurities and particulate matter in the water to prevent clogging of the drainage pipe. A plurality of filter grilles are provided around the surface of the filter barrel 6 to improve the filtering effect.

[0028] Drainage device 1 also includes a mounting bracket 5, located on one side of the top of water tank 3, for securing a drain pump 4 and a filter tank 6. Drain pump 4 is bolted to the top surface of one end of mounting bracket 5, facilitating removal and maintenance. The top of filter tank 6 is connected to the other end of mounting bracket 5, ensuring its stability.

[0029] In one embodiment of the present invention, the float triggering device 2 includes a floating plate 13, which is movably mounted on the filter tank 6 and moves up and down as the water level rises and falls. Multiple detachable airbags 14 are distributed around the bottom surface of the floating plate 13. Each airbag 14 is equipped with an air pressure regulating valve, which allows the buoyancy of the floating plate 13 to be adjusted as needed, thereby achieving adaptability to different water levels. The floating plate 13 is made of high-density foam board, which provides excellent floating performance and stability.

[0030] Specifically, a connection portion 15 is provided on one side of the floating plate 13. The connection portion 15 is slidably connected to a limit rod 11. The limit rod 11 is disposed within the water tank 3 and welded to the bottom of the mounting frame 5. The provision of the limit rod 11 limits the range of movement of the floating plate 13, preventing the floating plate 13 from deflecting or falling off during the upward and downward movement.

[0031] In one embodiment of the present invention, the floating platform 13 is electrically connected to the drain pump 4 via a trigger mechanism. The trigger mechanism includes a trigger rod 16 and a trigger button 7. The trigger rod 16 is fixedly connected to the upper surface of one side of the floating platform 13. The trigger button 7 is located directly above the trigger rod 16 and connected to the lower surface of the mounting bracket 5. When the floating platform 13 rises to a certain height, the trigger rod 16 contacts the trigger button 7, thereby activating the drain pump 4 to drain water.

[0032] The coal mine underground sump drainage system with application number CN202222170343.5 can stably connect the hose to the water pump and the main drainage pipe and ensure the stable operation of the drainage system, but it still requires manual attention during use to monitor the water level and control the water pump to drain the water in the sump. Moreover, during the drainage process, the water in the sump may contain impurities and particulate matter, which can easily clog the drainage pipe during the drainage process and affect the drainage efficiency. The drainage device 1 used in the utility model cooperates with the floating trigger device 2. The floating plate 13 rises and falls in the sump 3 as the water level rises and falls. When the preset maximum water level is reached, the trigger guide rod 16 can contact the trigger button 7 to activate the drainage pump 4 to drain the water, thereby achieving an automatic drainage effect in the sump 3.

[0033] It should be noted that the running time of the drainage pump 4 after starting can be preset by the controller, such as being kept running for 5-10 minutes.

[0034] Furthermore, the cleaning device 8 arranged at the bottom of the floating plate 13 moves along the surface of the filter barrel 6 through two cleaning rings 17 distributed above and below, and floats and cleans its surface through the brush strip 18, thereby preventing impurities from clogging the drainage pipe.

[0035] Specifically, the bottom of the floating plate 13 is connected to a cleaning device 8, which is connected to the surface of the filter drum 6. The cleaning device 8 comprises two cleaning rings 17, one above the other, connected by a connecting rod 19 and sleeved onto the filter drum 6. Brush strips 18 are arranged around the inner walls of the cleaning rings 17, which contact and rub against the surface of the filter drum 6 to clean the filter drum 6. As the floating plate 13 rises with the water level, the cleaning device 8 also rises, cleaning the filter drum 6 as it rises. When the water level drops, the floating plate 13 and cleaning device 8 also descend, returning to their initial positions.

[0036] Among them, mounting plates 9 are provided on both sides of one end of the mounting frame 5, and insertion rods 12 are provided on the mounting plates 9. The provision of the insertion rods 12 facilitates the fixation and installation of the equipment in the water tank 3 and improves the stability and reliability of the equipment.

[0037] The operating principle is as follows: as the water level in the water tank 3 rises, the floating plate 13 rises with it. When the floating plate 13 reaches a certain height, the trigger guide rod 16 contacts the trigger button 7, thereby activating the drain pump 4 to drain the water. Simultaneously, the rising floating plate 13 also causes the cleaning device 8 to rise, cleaning the filter tank 6 as it ascends. When the water level drops, the floating plate 13 and cleaning device 8 also descend, returning to their initial positions. By adjusting the air pressure in the airbag 14, the buoyancy of the floating plate 13 can be adjusted to accommodate varying water levels.

[0038] In summary, the present invention achieves automatic drainage of a coal mine water tank through the cooperation of the drainage device 1 and the floating trigger device 2. It also cleans the filter barrel 6 during the drainage process, preventing the problem of impurities and particulate matter clogging the drainage pipe. Furthermore, the provision of components such as the airbag 14 and the air pressure regulating valve improves the adaptability and maintenance convenience of the device.
