Technical Field
[0001] The utility model relates to the technical field of coal mine water disaster control, in particular to a drainage device for coal mine water disaster control. Background Art
[0002] Coal mine water disaster is a major safety hazard in coal mine production. It not only affects the normal production of coal mines, but also may lead to serious safety accidents, such as the flooding of mine water, causing the inundation of the mine, and even threatening the lives of miners. In order to prevent the occurrence of water disasters, coal mines need to establish an effective drainage system.
[0003] The drainage system for coal mine water disaster control usually consists of a drainage pump, a motor, a suction pipe, a drainage pipe and a control system. The drainage pump is the core component, generally a centrifugal pump. Its working principle is to rely on the high-speed rotating impeller to drive the water to do centrifugal motion, so that the water obtains kinetic energy and pressure energy. The water is sucked in at the center of the impeller and is thrown out at high speed at the edge of the impeller, thus forming a pressure difference to continuously pump out the water; the motor provides power for the drainage pump, usually an AC motor, which converts electrical energy into mechanical energy to drive the rotation of the impeller of the drainage pump; one end of the suction pipe is connected to the sump or the water accumulation area, and the other end is connected to the water inlet of the drainage pump, and its function is to introduce the accumulated water into the drainage pump; the drainage pipe is connected to the water outlet of the drainage pump to transport the pumped water to a designated location, such as the ground or other safe areas; the control system is used to control the start, stop, speed regulation and other operations of the drainage pump, and can automatically control the operation of the drainage pump according to the information fed back by monitoring devices such as water level sensors to keep the water level in the sump within a safe range.
[0004] Traditional drainage methods mainly discharge water through drainage pipes. However, the water in the mine often contains many ores or larger particles, and some ordinary treatment devices do not have the function of filtration, resulting in damage to the water pump during pumping, affecting the service life of the water pump and the water treatment effect. In addition, the failure to clean the sump in time reduces the effective capacity and affects the drainage efficiency. Therefore, a drainage device for coal mine water disaster control is proposed to solve the above problems. Summary of the Utility Model

Specific implementation manners
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, an embodiment provided by the present utility model: a drainage device for coal mine water disaster control, including a collection box 1. In the middle of the inner bottom end of the collection box 1, a first water sump 2 is fixedly connected. On the left and right ends of the first water sump 2 inside the collection box 1, collection drawers 3 are slidably connected. The front sides of the two collection drawers 3 are located at the front end of the collection box 1. At the front and rear ends inside the collection box 1, convex baffles 5 are fixedly connected. On the top of the first water sump 2, a second water sump 6 is fixedly connected. A cover plate 7 is attached to the top of the second water sump 6. In the middle of the cover plate 7, a water inlet pipe 8 is fixedly connected. The bottom end of the water inlet pipe 8 is located inside the second water sump 6. In the middle of the left and right ends of the first water sump 2, through grooves 11 are opened. On the outside of the through grooves 11 at the left and right ends of the first water sump 2, sealing grooves 12 are opened. On the inner left and right ends of the first water sump 2, retaining grooves 13 are opened. At the top of the opposite ends of the retaining grooves 13, water retaining plates 14 are rotatably connected. The water retaining plates 14 are engaged with the adjacent retaining grooves 13. Filter components are arranged at the left and right ends of the first water sump 2. The opposite sides of the two filter components are attached. The filter components are used to filter particulate matters such as ores in the coal mine water. Driving components are arranged at the front and rear ends of the first water sump 2. The two driving components are used to drive the filter components connected thereto to move out of the inside of the first water sump 2. At the bottom of the front end of the collection box 1, a water pump 10 is fixedly connected. The output end of the water pump 10 is fixedly connected with a water outlet pipe 9. The rear end of the water outlet pipe 9 is located at the inner bottom end of the first water sump 2.
[0027] Water flows into the inside of the second water sump 6 and the first water sump 2 through the water inlet pipe 8. The water pump 10 is started, so that the water outlet pipe 9 pumps out the water inside the first water sump 2 and conveys it to the position at the end of the water outlet pipe 9. The ore particles in the water can be intercepted by the filter components, preventing the ore particles from entering the inside of the water pump 10, thus causing damage to the water pump 10 and blockage of the water outlet pipe 9. Through the cooperation of the driving components and the filter components, the intercepted ore particles can be collected inside the collection drawers 3, preventing the accumulation of more particulate matters such as ores in the second water sump 6 and the first water sump 2 from affecting the drainage efficiency.
[0028] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6, The two filtering components are symmetrical. The left filtering component includes a connecting plate 23. The right side of the connecting plate 23 is attached to the left side of the first water tank 2. The right side of the connecting plate 23 is fixedly connected with an intercepting frame 24. The left end of the connecting plate 23 is provided with a handle 25. The middle of the right end of the handle 25 is fixedly connected with a connecting column 26. The right end of the connecting column 26 penetrates through the left ends of the connecting plate 23 and the intercepting frame 24 and is fixedly connected with a limiting plate 27. The front and rear ends of the right side of the handle 25 are both fixedly connected with clamping blocks 28. The left end of the connecting plate 23 is provided with clamping grooves 29 at the corresponding positions of the two clamping blocks 28. The middle parts of the front and rear ends of the connecting plate 23 are both fixedly connected with T-shaped blocks 31. The right side of the connecting plate 23 is fixedly connected with a sealing ring 30 around the intercepting frame 24. The connecting column 26 is slidably connected with the left ends of the connecting plate 23 and the intercepting frame 24. The clamping block 28 is engaged with the adjacent clamping groove 29 on the same side. The front and rear ends of the inner side of the collecting box 1 are provided with first sliding grooves 4 on the left and right sides of the first water tank 2. The T-shaped block 31 is slidably connected with the adjacent first sliding groove 4 on the same side. The sealing ring 30 is engaged with the sealing groove 12 on the same side. The opposite sides of the two intercepting frames 24 are attached to each other.
[0029] When the opposite sides of the two intercepting frames 24 are attached to each other, it is convenient to block the ore particles in the water entering the interior of the first water tank 2 at the top of the intercepting frame 24. When the ore particles on the intercepting frame 24 accumulate too much and affect the drainage efficiency, the opposite sides of the intercepting frame 24 are respectively located on the left and right sides of the first water tank 2. When the connecting plate 23 moves, it will drive the T-shaped block 31 to slide inside the adjacent first sliding groove 4 on the same side, and at the same time provide support for the connecting plate 23 and the intercepting frame 24. By moving the handle 25 outward from the connecting plate 23, the clamping block 28 is disengaged from the clamping groove 29, then the handle 25 is rotated 180 degrees, and then the clamping block 28 is engaged with the rack 19 on the same side, so as to fix the bottom of the intercepting frame 24 above, which is convenient to pour the ore particles on the intercepting frame 24 into the collecting drawer 3 on the same side for collection and at the same time convenient to clean the intercepting frame 24.
[0030] Refer to Figure 2 、 Figure 3 and Figure 4, it is symmetrical between the two driving components. The front driving component includes a motor 20 and two moving columns 16. The motor 20 is fixedly connected to the front side inside the collection box 1. The motor 20 is located at the inner end of the convex baffle 5. The output end of the motor 20 is fixedly connected with a rotating shaft 21. The rear end of the rotating shaft 21 is fixedly connected with a gear 22. A slider 18 is fixedly connected to the right side of the rear end of the upper moving column 16 and the left side of the rear end of the lower moving column 16. A dirt blocking plate 17 is fixedly connected to the rear part of the opposite ends of the moving columns 16. A rack 19 is fixedly connected to the inside of the opposite ends of the moving columns 16. The opposite ends of the gear 22 and the rack 19 are meshed and connected. The left end of the upper rack 19 is located at the left end of the upper moving column 16. The right end of the lower rack 19 is located at the right end of the lower moving column 16. The left ends of the two upper racks 19 are respectively fixedly connected to the tops of the front and rear ends of the left connecting plate 23. The right ends of the two lower racks 19 are respectively fixedly connected to the bottoms of the front and rear ends of the right connecting plate 23. A chute two 15 is provided in the middle right part of the upper moving column 16 at the front and rear ends of the water tank one 2. A chute two 15 is provided in the middle left part of the lower moving column 16 at the front and rear ends of the water tank one 2. The slider 18 is respectively slidably connected to the adjacent chute two 15 on the same side.
[0031] Start the motor 20 to drive the rotating shaft 21 and the gear 22 to rotate counterclockwise. Since the opposite ends of the gear 22 and the upper and lower racks 19 are meshed and connected, when the gear 22 rotates, it will drive the two racks 19 to displace in the opposite direction. Since the left end of the upper rack 19 is fixedly connected to the left connecting plate 23, when the upper rack 19 generates displacement, it will drive the connecting plate 23 to move to the left. Since the right end of the lower rack 19 is fixedly connected to the right connecting plate 23, when the lower rack 19 generates displacement, it will drive the right connecting plate 23 to move to the right. In addition, the rack 19 is respectively fixedly connected to the moving column 16 on the same side. Therefore, the movement of the rack 19 will move synchronously with the fixed moving column 16, so that the slider 18 slides inside the adjacent chute two 15 on the same side.
[0032] Working principle: The water in the mine enters the interior of the first water sump 2 through the water inlet pipe 8, and then falls into the bottom of the inner end of the first water sump 2 through the interception frame 24. The water pump 10 is started, so that the water outlet pipe 9 conveys the filtered water to the corresponding place, while the ore particles in the water are blocked on the interception frame 24. When the ore particles carried on the interception frame 24 are too many and cause the water flow filtration speed to slow down, the motor 20 is started synchronously, so that the upper and lower two racks 19 on the same side generate displacement, thereby driving the connecting plate 23 fixed to the rack 19 to move. When the slider 18 moves to the end of the adjacent second chute 15 on the same side, the opposite sides of the interception frame 24 are respectively located on the left and right sides of the first water sump 2. At this time, the water baffle 14 loses support and engages with the retaining groove 13 on the same side, preventing the water flow from flowing out of the through groove 11 to the outside of the first water sump 2. By moving the handle 25 to the outside of the connecting plate 23, the clamping block 28 is disengaged from the clamping groove 29, and then the handle 25 is rotated 180 degrees to invert the interception frame 24, so as to facilitate pouring the ore particles on the interception frame 24 into the collection drawer 3 on the same side for collection. During the process of pouring the ore particles, the handle 25 is pushed towards the connecting plate 23, so that the clamping block 28 engages with the clamping groove 29, so that the bottom of the interception frame 24 always faces upward, which is convenient for cleaning the interception frame 24.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
