Description

Technical Field

[0001] This utility model relates to the technical field of underground water control devices in coal mines, and in particular to an underground water control device for coal mines. Background Technology

[0002] Coal mine geological engineering requires the collection of existing geological, hydrogeological, and production data from adjacent mining areas, and the full utilization of geological and hydrogeological boreholes to meet the requirements of engineering geological surveys. Among these, water control in coal mines is a crucial aspect of ensuring safe production. It is necessary to drain the accumulated water in the coal mine into nearby rivers and lakes to prevent the water level from rising continuously and threatening the personal safety of workers.

[0003] Existing coal mine underground water control devices, such as the one shown in patent number CN220788156U, require multi-stage filtration of the pumped water before it can be discharged. However, during the filtration process, impurities in the discharged water can easily clog the filter screen, thus affecting the drainage speed. Therefore, it is necessary to design a coal mine underground water control device. Utility Model Content

[0004] Therefore, it is necessary to provide a coal mine underground water control device to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a coal mine underground water control device, including a frame and several connecting plates. A screw conveyor is installed inside the frame, with a feed inlet above the screw conveyor and a filter screen installed below it. A drive shaft is rotatably installed inside the frame, and an arc-shaped cleaning plate is mounted on the drive shaft. Several cleaning blocks are mounted on the arc-shaped cleaning plate, with the diameter of the cleaning blocks being smaller than the diameter of the filter screen's mesh. A guide rail and a filter screen are provided inside the frame, and a movable frame is slidably engaged on the guide rail. Several connecting plates are hinged together, with the two outermost connecting plates hinged to the frame and the guide rail, respectively. Connecting ropes one and two are wound around both ends of the drive shaft, and both connecting ropes one and two are connected to the movable frame. Several cleaning blocks are mounted on the connecting plates, with the diameter of the cleaning blocks being smaller than the diameter of the filter screen's mesh.

[0006] Preferably, a guide shaft is rotatably mounted inside the frame, and a connecting rope passes through the guide shaft and is connected to the movable frame.

[0007] Preferably, a guide shaft two is rotatably installed inside the frame, and the connecting rope two is connected to the moving frame after passing through the guide shaft two.

[0008] Preferably, both guide shaft one and guide shaft two are provided with chamfers.

[0009] Preferably, a plurality of rotating shafts are rotatably mounted on the mobile frame, and the rotating shafts abut against the guide rail.

[0010] Preferably, the output end of the screw conveyor is provided with a first storage box, and the output end of the second filter screen is provided with a second storage box.

[0011] Preferably, the second filter screen is provided with guide plates on both sides, and the second filter screen is inclined.

[0012] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0013] 1. By driving the drive shaft to rotate, the arc-shaped cleaning plate will rotate towards the filter screen one, and the cleaning block one will be able to insert into the mesh of the filter screen one, pushing out the impurities blocking the mesh, thereby achieving the purpose of cleaning the filter screen one;

[0014] 2. As the drive shaft rotates the arc-shaped cleaning plate toward the filter screen, the first connecting rope extends and the second connecting rope winds and contracts, thereby moving the moving frame along the guide rail, so that several connecting plates can be straightened, and the second cleaning block can clean the mesh of the second filter screen.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 4 This application provides a coal mine underground water control device, including a frame 1 and several connecting plates 10. A screw conveyor 2 is installed inside the frame 1, with a feed inlet above the screw conveyor 2. The screw conveyor 2 is prior art and will not be described in detail. A filter screen 3 is installed below the screw conveyor 2. A drive shaft 4 is rotatably installed inside the frame 1, and an arc-shaped cleaning plate 5 is installed on the drive shaft 4. Several cleaning blocks 6 are installed on the arc-shaped cleaning plate 5, with the diameter of the cleaning blocks 6 being smaller than the diameter of the mesh of the filter screen 3. A guide rail 7 is provided inside the frame 1. The filter screen 8 and the guide rail 7 are slidably connected to a movable frame 9. Several connecting plates 10 are hinged to each other. The two outermost connecting plates 10 are respectively hinged to the frame 1 and the guide rail 7. The two ends of the drive shaft 4 are respectively wound with connecting rope 11 and connecting rope 2 12. Both connecting rope 11 and connecting rope 2 12 are connected to the movable frame 9. Several cleaning blocks 2 13 are installed on the connecting plates 10. The diameter of the cleaning blocks 2 13 is smaller than the diameter of the mesh of the filter screen 8. The same movable frame 9 is slidably connected to two symmetrically arranged guide rails 7.

[0022] In this embodiment, the extracted mine water flows into the screw conveyor 2 through the feed inlet on the frame 1. Large impurities are conveyed and pushed out by the screw conveyor 2, while small impurities and water fall from the filter screen 3 below the screw conveyor 2 onto the filter screen 8. The small impurities are then intercepted by the filter screen 8, while the water flows down from the filter screen 8. When the filter screen needs to be cleaned, the drive shaft 4 can be manually rotated, causing the arc-shaped cleaning plate 5 on the drive shaft 4 to rotate. The arc-shaped cleaning plate 5 is then rotated to be concentric with the filter screen 3, allowing several cleaning blocks 6 on the arc-shaped cleaning plate 5 to be inserted into the mesh of the filter screen 3, pushing out any impurities that may be stuck in the mesh. Thus, the impurities can continue to be conveyed by the screw conveyor 2. At the same time as the drive shaft 4 rotates, the connecting rope 11 wound around it... The connecting rope 12 extends and then contracts, pulling the movable frame 9 that slides on the guide rail 7. The movable frame 9 moves the hinged connecting plate 10, straightening several connecting plates 10. The cleaning block 13 on the connecting plate 10 can be inserted into the mesh of the filter screen 8 to push out and clean any impurities that may be stuck in the mesh of the filter screen 8. After cleaning, the drive shaft 4 is rotated in the opposite direction, and the arc-shaped cleaning plate 5 can be rotated back to its original position. The connecting rope 11 is then wound and contracts, and the connecting rope 12 is released and extended, allowing the movable frame 9 to slide back on the guide rail 7 to its original position. During the resetting process, since the connecting plates 10 are hinged and have gaps, there will be no squeezing or collision between the connecting plates 10, thus affecting the sliding back of the movable frame 9. When the movable frame 9 is moved to its maximum extent, that is, when all the hinged connecting plates 10 are straightened, the connecting plates 10 are arranged parallel to the filter screen 2 8, so that the cleaning block 2 13 on the connecting plate 10 can be inserted into the mesh of the filter screen 2 8; since the diameters of the cleaning block 1 6 and the cleaning block 2 13 are smaller than the diameter of the mesh, the arc-shaped cleaning plate 5 and the connecting plate 10 will not collide with the filter screen 1 3 or the filter screen 2 8.

[0023] In some embodiments, to facilitate the guidance of the connecting rope 11, a guide shaft 14 is rotatably mounted inside the frame 1. The connecting rope 11 passes through the guide shaft 14 and is connected to the movable frame 9. Thus, the guide shaft 14 can guide the connecting rope 11 so that when it pulls the movable frame 9, the movable frame 9 can be reset.

[0024] In some embodiments, to facilitate the guidance of the connecting rope 12, a guide shaft 15 is rotatably mounted inside the frame 1. The connecting rope 12 passes through the guide shaft 15 and connects to the movable frame 9. Thus, the guide shaft 15 can guide the connecting rope 12, enabling the movable frame 9 to move when it is pulled.

[0025] In some embodiments, to reduce friction when connecting rope 11 and connecting rope 2 12 extend and retract, both guide shaft 14 and guide shaft 2 15 are provided with chamfers.

[0026] In some embodiments, to facilitate the sliding of the movable frame 9 on the guide rail 7, a plurality of rotating shafts 16 are rotatably mounted on the movable frame 9, and the rotating shafts 16 abut against the guide rail 7.

[0027] In some embodiments, to facilitate the collection of impurities output after filtration by filter screen 3 and filter screen 8, a storage box 17 is provided at the output end of the screw conveyor 2, and a storage box 28 is provided at the output end of filter screen 8.

[0028] In some embodiments, to prevent the material being pushed out and cleaned on the filter screen 8 from sliding off its sides, guide plates 19 are provided on both sides of the filter screen 8, and the filter screen 8 is inclined.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
