[0002] Coal mines refer to places rich in coal resources, which are generally divided into underground coal mines and open-pit coal mines. At present, underground water hazards in coal mines affect the progress and quality of mine construction, worsen the working environment of workers, increase the drainage facilities and drainage costs of mines, and bring unsafe factors to mine production. Therefore, drainage is often required in coal mine geological engineering to lower the groundwater level and prevent groundwater from pouring into mines or engineering areas to ensure the safe implementation of coal mine geological engineering.

[0003] The above-mentioned and existing related technologies often have the following defects: when drainage work is carried out underground in coal mines, a pumping pipe is usually used for drainage.

By setting the filtering device 4, the granular matter in the mine water can be effectively filtered to avoid the granular matter from damaging the water pump 1, thereby improving the service life and drainage efficiency of the water pump 1 and ensuring the normal operation of the coal mine geological engineering.

At this time, the spring 48 begins to drive the limiting plate 49 to the surface of the frame 43 with its own elastic force, so that the position of the frame 43 can be fixed, and the limiting plate 49, the spring 48 and the limiting frame 46 can achieve the effect of regularly replacing the filter plate 44, avoiding In order to avoid the situation where the filter plate 44 is blocked by particulate matter due to long-term use, the working efficiency of the water pump 1 is improved. The surface of the limit frame 46 is fixedly connected with a guide rod 47, and the limit plate 49 is slidably connected to the guide rod 47. The spring 48 is sleeved on the arc surface of the guide rod 47. The limit plate 49 will slide along the arc surface of the guide rod 47 while sliding.

The surface of the filter box 41 is installed with a guardrail 42. The guardrail 42 can block larger particulate matter in the mine water and prevent larger volume of particulate matter from entering the water pump 2 with the running water. At the same time, it can avoid the situation where larger particulate matter hits the filter plate 44 and causes damage, thereby extending the service life of the filter plate 44 to a certain extent.

[0033] Reference Figure 2 and Figure 5 as well as Figure 6 As shown, specifically, the anti-clogging device 5 includes a fixed plate 54, which is fixedly connected to the filter box 41, and a round rod 55 is rotatably connected to the surface of the fixed plate 54, and the arc surface of the round rod 55 is fixedly connected to the impact frame 57, and the arc surface of the round rod 55 is sleeved with a torsion spring 56, and the two ends of the torsion spring 56 are respectively fixedly connected to the fixed plate 54 and the impact frame 57, and the surface of the filter box 41 is fixedly connected to the waterproof box 51, and the inner wall of the waterproof box 51 is fixedly connected to the motor 59, and the output end of the motor 59 is fixedly connected to the extrusion plate 52, and the surface of the extrusion plate 52 is rotatably connected to the roller 53, and the roller can reduce the friction between the extrusion plate 52 and the impact plate, so as to make it more convenient for the extrusion plate 52 to squeeze the impact plate, and the surface of the impact frame 57 is glued with a protective pad 58, and the protective pad 58 is made of rubber. The protective pad 58 can protect the filter plate 44, reduce the impact force, and extend the service life of the filter plate 44.

[0034] Working principle: When draining water underground in a coal mine, a filter device 4 is required. First, the water pump 1 is started. The water suction end of the water pump 1 uses the suction pipe 2 to pump water, and then discharges it with the help of the drainage pipe 3. When pumping water, the mine water passes through the filter plate 44 in the filter box 41, and then flows into the suction pipe 2. At this time, the granular matter in the mine water can be filtered. If the filter plate 44 is used for a long time, it needs to be replaced. First, pull the limit plate 49 away from the handle 45. The limit plate 49 moves along the filter box 41. The surface of the filter box 41 slides, and the limit plate 49 squeezes the spring 48. When the limit plate 49 is out of contact with the frame 43, the handle 45 is pulled, and the handle 45 drives the frame 43 to slide along the inner wall of the filter box 41 until the frame 43 is out of contact with the filter box 41. At this time, the removal of the filter plate 44 is completed, and then the new filter plate 44 and the frame 43 are slidably installed on the filter box 41, and then the limit plate 49 is released. At this time, the spring 48 begins to use its own elastic force to drive the limit plate 49 to press against the frame 43. The surface of the filter box 41 can fix the position of the frame 43, and the limit plate 49, the spring 48 and the limit frame 46 can achieve the function of regularly replacing the filter plate 44, avoiding the situation that the filter plate 44 is blocked by granular matter due to long-term use of the filter plate 44, thereby improving the working efficiency of the water pump 1. The limit plate 49 will slide along the arc surface of the guide rod 47 while sliding, and the guide rod 47 can avoid the bending of the spring 48 and improve the performance of the spring 48. A guardrail 42 is installed on the surface of the filter box 41. The guardrail 42 can block larger granular matter in the mine water and prevent larger granular matter from entering the pumping pipe 2 with the flowing water. At the same time, it can avoid the situation that larger granular matter hits the filter plate 44 and causes damage, and prolongs the service life of the filter plate 44 to a certain extent. By setting the filtering device 4, the granular matter in the mine water can be effectively filtered to avoid the granular matter from damaging the water pump 1, thereby improving the service life and drainage efficiency of the water pump 1 and ensuring the normal operation of the coal mine geological engineering.

[0035] During drainage, the anti-clogging device 5 is required to ensure the normal filtration of the filter plate 44. First, the motor 59 is started. The output end of the motor 59 will drive the extrusion plate 52 to rotate. The rotation of the extrusion plate 52 will drive the roller 53 to rotate. When the roller 53 contacts the impact frame 57, it will drive the impact frame 57 to rotate. At this time, the impact frame 57 will squeeze the torsion spring 56. When the roller 53 is out of contact with the impact frame 57, the torsion spring 56 starts to drive the protective pad 58 on the impact frame 57 to impact the filter plate 44, so that the granular matter on the filter plate 44 can be knocked off. The roller 53 can reduce the friction between the extrusion plate 52 and the impact plate, thereby better The extrusion plate 52 is convenient for squeezing the impact plate, and the protective pad 58 can protect the filter plate 44, reduce the impact force, and extend the service life of the filter plate 44. By setting the anti-clogging device 5, the waterproof box 51, the extrusion plate 52, the fixed plate 54, the round rod 55, the torsion spring 56, the impact frame 57 and the motor 59 cooperate with each other to knock the granular matter attached to the filter plate 44 off, so as to avoid the granular matter from causing the surface of the filter plate 44 to be blocked. At the same time, the granular matter can be prevented from blocking the filter plate 44, ensuring that the filter screen remains unobstructed, thereby ensuring the normal drainage work and maintaining the pumping rate of the pumping pipe 2.
