Technical Field
[0001] The utility model belongs to the technical field of mine water pumps, and particularly relates to a coal slime protection cover for a water pump. Background Art
[0002] Before coal mining work is carried out, it is often necessary to use mining machines to excavate the mine. During the process of mine construction, it is often necessary to use a water pump to pump out the water in the mine to keep the mine dry, which is convenient for subsequent workers to carry out coal mining work.
[0003] At present, during the process of mine construction, the drill will break the surrounding rock layers containing some coal mines, resulting in a large amount of coal slime and sundries in the underground accumulated water inside the mine. However, the existing water pumps cannot filter these coal slime and sundries, and the drain pipe is easily blocked by coal slime and sundries during use, seriously affecting the drainage effect.
[0004] Therefore, in view of the problem that the existing mine water pumps do not have the function of filtering and blocking coal slime and sundries, resulting in the blockage of the water pump by these coal slime and sundries, the drain outlet cannot drain water normally, and the drainage efficiency is reduced, a coal slime protection cover for a water pump is designed. The coal slime and sundries are isolated by the protection cover to ensure the normal operation of the water pump. Summary of the Utility Model
[0005] In order to overcome the problem that during the operation of the existing water pump, the coal slime and sundries in the mine groundwater are easy to block the water pump, resulting in the blockage of the water pump and the reduction of the drainage efficiency.

The nylon net can be fixed to the fixed frame through the cable ties, and the nylon net can be replaced by cutting the cable ties.
[0010] Preferably, a first limit post is fixedly connected to one side of the water pump, and a second limit post that is opposite to the first limit post left and right is threadedly connected to the other side of the water pump. Support is formed by the first limit post and the second limit post, and the second limit post can be detached from the water pump.
[0011] Preferably, two hooks that are opposite to each other left and right are welded on the upper support ring. The two hooks are respectively sleeved on the first limit post and the second limit post. The hooks cooperate with the first limit post and the second limit post for fixation.

[0014] The beneficial effects of the present utility model:
[0015] 1. By installing a protective cover composed of a fixed frame and nylon cloth on the existing water pump inlet, the nylon net can block larger coal slime and sundries outside, while the underground water in the mine can pass through the small holes in the nylon net, avoiding the blockage of the drain pipe without affecting the water pumping efficiency of the water pump;
[0016] 2. The first limit post and the second limit post cooperate with the hooks for fixation.

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0024] Please refer to Figures 1-5 , the present utility model provides an embodiment: The coal-slurry-proof shield of the water pump 1 includes a water pump 1, a water inlet 2, a drain pipe 3, a fixed frame and a nylon net 4; a water pump 1 is arranged outside the mine, a water inlet 2 is opened at the bottom end of the water pump 1, a drain pipe 3 penetrating through the outer wall of one side of the water pump 1 is fixedly connected to the water pump 1, a one-way valve is arranged in the water inlet 2, a barrel-shaped fixed frame welded by round steel is sleeved outside the water inlet 2 of the water pump 1, and a nylon net 4 is sleeved on the fixed frame. By installing a protective cover composed of a fixed frame and nylon cloth on the existing water inlet 2 of the water pump 1, a number of equidistant small holes are opened on the nylon net 4, which can block larger coal slime and sundries outside, while the groundwater in the mine can pass through the small holes on the nylon net 4, avoiding the blockage of the drain pipe 3 without affecting the pumping efficiency of the water pump 1.
[0025] Please refer to Figures 2-4, in this embodiment, the fixing frame is composed of two circular steel support rings 5 opposite to each other up and down, and a ring of support columns 6 are welded between the two support rings 5. A ring of cable ties 7 are sleeved on both the upper and lower support rings 5, and the nylon net 4 is fixed between the cable ties 7 and the support rings 5. One side of the water pump 1 is fixedly connected with a first limit post 8, and the other side of the water pump 1 is threadedly connected with a second limit post 9 which is opposite to the first limit post 8 left and right. Two hooks 10 opposite to each other left and right are welded on the upper support ring 5, and the two hooks 10 are respectively sleeved on the first limit post 8 and the second limit post 9. The fixing frame formed by the cooperation of the support ring 5 and the support columns 6 can support the nylon net 4, preventing the relatively soft nylon net 4 from piling up. The nylon net 4 can be fixed on the fixing frame through the cable ties 7, and the nylon net 4 can be replaced by cutting the cable ties 7. When replacing the nylon net 4, it is supported by the first limit post 8 and the second limit post 9. The second limit post 9 can be detached from the water pump 1, and the hooks 10 cooperate with the first limit post 8 and the second limit post 9 for fixation. By detaching the second limit post 9, the protective cover can be detached from the water pump 1.
[0026] Please refer to Figure 5 , in this embodiment, a limit sleeve 11 sleeved on the mine shaft is arranged outside the water pump 1. Two annular clamping blocks 12 opposite to each other left and right are arranged inside the limit sleeve 11. The water pump 1 is arranged inside the clamping blocks 12. A threaded rod 13 is inserted into the limit sleeve 11, and a guide rod 14 is fixedly connected inside the limit sleeve 11. A threaded hole matching the threaded rod 13 is opened on the clamping block 12. A motor 15 is fixedly connected to the threaded rod 13. The limit sleeve 11 is sleeved on the mine shaft, and the water pump 1 can be fixed on the mine shaft by cooperating with the clamping blocks 12. The threaded rod 13 is a threaded rod with a double-thread structure. The motor 15 drives the threaded rod 13 to rotate. Under the limitation of the guide rod 14, the two clamping blocks 12 move towards the central position to clamp and fix the water pump 1.
[0027] When working, first, the staff passes the limit sleeve 11 through the water pump 1 from below, and then starts the motor 15. The motor 15 drives the threaded rod 13 to rotate.

Under the limitation of the guide rod 14, the two clamping blocks 12 move towards the middle and clamp the outer wall of the water pump 1 for fixation;
[0028] Then, fix the nylon net 4 on the fixing frame with cable ties 7. Then, hang one end of the hook 10 on the first limiting post 8. Then, pass the second limiting post 9 through the hook 10 on the other side, and then turn the second limiting post 9 to fix it on the water pump 1. Then, insert the bottom end of the water pump 1 equipped with the protective cover into the mine, and sleeve the limiting sleeve 11 on the mine for fixation. Start the water pump 1. The protective cover blocks the coal slime and sundries outside the nylon net 4. The groundwater passes through the mesh holes on the nylon net 4 and enters the water pump 1 along the water inlet 2, and is discharged along the drain pipe 3.
[0029] Through the above steps, a protective cover composed of a fixing frame and nylon cloth is installed on the water inlet 2 of the existing water pump 1. A number of equidistant small holes are provided on the nylon net 4, which can block the relatively large coal slime and sundries outside, while the groundwater in the mine can pass through the small holes on the nylon net 4. Without affecting the pumping efficiency of the water pump 1, it can avoid the blockage of the drain pipe 3, so as to solve the problem that the coal slime and sundries in the mine groundwater are easy to block the water pump 1 during the operation of the existing water pump 1, resulting in the blockage of the water pump 1 and the reduction of the drainage efficiency.
[0030] The above has described in detail the embodiments of the present invention in conjunction with the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can also be made without departing from the purpose of the present invention.
