Abstract

This invention discloses an automatic water pumping system and its operating method, including a base with expandable water storage bags evenly spaced above it. When the expandable water storage bags are not in use, a support plate can cover the top of the support frame. One end of the support frame can also limit multiple sets of frames, compressing temporarily unused expandable water storage bags together, thus saving underground space. After the support plate is laid flat, the top of the support plate can be easily crossed by underground workers, facilitating underground traffic and the flow of personnel and materials, improving convenience. This invention can rationally and centrally store accumulated water in various sub-tunnels. Then, by observing the total water volume after collection, a corresponding water pumping plan can be formulated, enabling scientific response and reducing the likelihood of errors in any stage of the water pumping process, thereby improving the efficiency of underground water pumping.

Description

Technical Field

[0001] This invention relates to the field of mine water pumping technology, specifically to an automatic water pumping system and its operating method. Background Technology

[0002] The primary reason for pumping water into mines is to ensure production safety, stabilize mine pressure, and improve production efficiency. Mines typically contain large amounts of groundwater, which can pose safety hazards to coal mine production, potentially leading to floods and other accidents, disrupting normal operations. Pumping effectively reduces groundwater accumulation, lowers the risk of flooding, optimizes the production environment, and ensures production safety. Mine drainage aims to discharge mine water gushing from underground to the surface through a drainage system, ensuring safe production and the safety of workers. Otherwise, accumulated mine water can disrupt normal production and even cause mine flooding accidents, resulting in significant loss of life and property.

[0003] Existing mine water pumping equipment often has the following defects in use:

[0004] The generation of water accumulation in mines is not stable, and the mine tunnels are crisscrossed, making it impossible for the water pumping system to plan drainage according to the water volume. This results in low drainage efficiency and requires staff to continuously monitor the water volume and operate the water pumping system.

[0005] The system cannot achieve the principle of storing water before draining it. The underground space is small, making it difficult to store the water. If the water volume is small and the mine is deep, the water pumping system cannot effectively drain the small amount of water, nor can it store the water. The water is prone to seepage, causing erosion and damage to the underground environment. Summary of the Invention

A second fixing strip is installed on the bottom of the expansion water storage bag, a support rod is installed on the bottom of the second fixing strip, and the bottom of the support rod is connected to the bottom of the inside of the frame.

[0015] Preferably, the sliding assembly includes a support frame, the interior of which is hollow, and sliding grooves are provided on both the front and rear sides of the top of the support frame. A sliding rod is installed inside the sliding groove, and a sliding sleeve is slidably fitted onto the surface of the sliding rod. A connecting rod is installed on the top of the sliding sleeve, and the top of the connecting rod is connected to the bottom of the frame.

[0016] Preferably, the buffer assembly includes a damper, which is installed at the four corners of the top of the base. The top of the damper is connected to the bottom of the support frame. A spring is sleeved on the outside of the damper. The top of the spring is connected to the bottom of the support frame, and the bottom of the spring is connected to the top of the base.

[0017] Preferably, the conveying assembly includes a water storage tank, which is installed at one end of the top of the base. A first water pump is installed on the top of the water storage tank. The pumping end of the first water pump is connected to the interior of the water storage tank, and the draining end of the first water pump is connected to a flange pipe.

[0018] Preferably, the connecting assembly includes a first pipe body, a water pressure detector is installed on one side of the surface of the first pipe body, a control valve is connected to one end of the first pipe body, and the end of the control valve away from the first pipe body is connected to the interior of the water storage tank.

[0019] Preferably, the end of the first pipe away from the control valve is connected to the bottom of the expansion water storage bag on the side near the water storage tank, and a series pipe is connected in series between the bottoms of the expansion water storage bags. A valve is installed on the surface of the series pipe, and a support plate is hinged to the top of the support frame on the side away from the water storage tank. One side of the support plate is in contact with the surface of the frame on the side away from the water storage tank.

[0021] The working method of the automatic water dispensing system includes the following steps:

[0022] S1. Install a retractable water storage structure in a relatively spacious area within the main roadway, and connect the pipes used to drain the underground water to the outside of the wellhead to the water storage structure.

[0023] S2. Lay branch pipes for transporting water at water accumulation points in each sub-lane, and extend the branch pipes to connect them to the water storage structure.

[0024] S3. Install a measuring structure on the water storage structure for measuring water level and water pressure;

[0025] S4. The accumulated water in each sub-tunnel is transported to the water storage structure in the main tunnel. The water storage structure can expand and contract according to the current accumulated water volume to make reasonable use of space. After the water storage volume is measured by the measuring structure to reach the preset value, the drainage structure is activated to discharge the water in the water storage structure.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting up sliding and supporting components for the expansion water storage bags, the expansion water storage bags will expand accordingly as the water volume increases. The expansion water storage bags will push each other, and the pushing of the expansion water storage bags will drive the frame to move. The frame can move on the surface of the slide rod through the sliding sleeve, thus providing space for the capacity expansion of the expansion water storage bags. At the same time, the frame can still maintain stable support for the expansion water storage bags. Multiple sets of expansion water storage bags are interconnected, and the water storage capacity can be increased according to the underground water accumulation conditions.

[0028] 2. In this invention, when the expansion water storage bag is not in use, the top of the support frame can be covered by the support plate. One end of the support frame can also be used to limit multiple sets of frames, compressing the temporarily unused expansion water storage bags together, thus saving underground space. After the support plate is laid flat, the top of the support plate can also be easily stepped over by underground workers, facilitating underground traffic and the flow of personnel and materials, and improving convenience.

[0029] 3. Reasonably centralize and store the accumulated water in each sub-tunnel. Then, by observing the total amount of water after centralization, formulate a corresponding water pumping plan, such as the number of pumps to be used, the drainage time, and how to arrange the drainage water volume. This can scientifically respond to the situation, reduce the chance of oversights in any part of the water pumping process, and improve the efficiency of underground water pumping.

[0036] 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.

[0037] Example 1

[0038] Please see Figure 1-Figure 5The present invention provides a technical solution: an automatic water dispensing system, including a base 1, with expansion water storage bags 2 equidistantly arranged above the base 1. The outer surface of the expansion water storage bags 2 is made of a wear-resistant and puncture-resistant flexible and stretchable material, and the inner surface is equipped with a waterproof membrane, which can store water. At the same time, it can expand to both sides as the water volume increases, thereby increasing its internal volume and water storage capacity.

[0039] The external mounting of the expansion water storage bag 2 includes a support assembly for supporting the expansion water storage bag 2 and reducing its space occupation. The support assembly includes a frame 3, which is hollow inside. The frame 3 is positioned above the base 1, and the expansion water storage bag 2 is placed inside the frame 3. The frame 3 is made of high-strength metal material and is used to support the expansion water storage bag 2.

[0040] A first fixing strip 4 is installed at the top of the expansion water storage bag 2, and a first rope 5 is installed at the top of the first fixing strip 4. The top of the first rope 5 is connected to the top of the inside of the frame 3. A second fixing strip 6 is installed at the bottom of the expansion water storage bag 2, and a support rod 7 is installed at the bottom of the second fixing strip 6. The bottom of the support rod 7 is connected to the bottom of the inside of the frame 3. By setting the first fixing strip 4 and the first rope 5, the top of the expansion water storage bag 2 is connected to the frame 3, thereby fixing the top of the expansion water storage bag 2. By setting the support rod 7 and the second fixing strip 6, the bottom of the expansion water storage bag 2 is supported, and the expansion water storage bag 2 is connected to the frame 3.

[0041] The bottom of the support assembly is equipped with a sliding component to facilitate the expansion and horizontal movement of the water storage bag 2. The sliding component includes a support frame 8, which is hollow inside. Sliding grooves 9 are provided on the front and rear sides of the top of the support frame 8. A sliding rod 10 is installed inside the sliding groove 9. A sliding sleeve 11 is slidably fitted on the surface of the sliding rod 10. A connecting rod 12 is installed on the top of the sliding sleeve 11. The top of the connecting rod 12 is connected to the bottom of the frame 3. By setting up the sliding component, after the water inside the mine is transported into the water storage bag 2, the water storage bag 2 will expand accordingly with the increase of water volume. The water storage bags 2 will push each other. The pushing of the water storage bags 2 will drive the frame 3 to move. The frame 3 can move on the surface of the sliding rod 10 through the sliding sleeve 11. This provides space for the capacity expansion of the water storage bag 2, while the frame 3 can still maintain stable support for the water storage bag 2.

[0042] Buffer components for buffering water flow impact are installed at the four corners of the bottom of the sliding assembly. The bottom of the buffer components is connected to the top of the base 1. The buffer components include dampers 13, which are installed at the four corners of the top of the base 1. The top of the dampers 13 is connected to the bottom of the support frame 8. Springs 14 are sleeved on the outside of the dampers 13. The top of the springs 14 is connected to the bottom of the support frame 8, and the bottom of the springs 14 is connected to the top of the base 1. Water inside the mine will generate impact during transportation. As the water volume increases, the impact may cause vibration inside the roadway and equipment. By setting springs 14 and dampers 13, the impact can be effectively buffered, improving the stability of the water pumping system and ensuring that the water pumping system can work stably.

[0043] A filter assembly for filtering mine water is installed on the top of the base 1, and a conveying assembly for draining the water is installed on one side of the top of the base 1. The conveying assembly includes a water storage tank 15, which is installed at one end of the top of the base 1. A first water pump 16 is installed on the top of the water storage tank 15. The pumping end of the first water pump 16 is connected to the inside of the water storage tank 15, and the draining end of the first water pump 16 is connected to a flange pipe 17. The first water pump 16 is connected to a pipe leading to the outside of the well opening through the flange pipe 17. The first water pump 16 transports the underground water to the outside of the well, thereby achieving the purpose of pumping water.

[0044] The filtration assembly includes a filter box 23, which is installed on top of the base 1. A filter element is installed inside the filter box 23. A multi-connector water inlet pipe 24 is connected to one side of the filter box 23. A second water pump 25 is installed on top of the base 1. The pumping end of the second water pump 25 is connected to the drain end of the filter box 23. The drain end of the second water pump 25 extends to the top of the expansion water storage bag 2 and is connected to the top of the expansion water storage bag 2. The water inside the tunnel is connected to the filter box 23 through the multi-connector water inlet pipe 24. The water in each tunnel converges into the filter box 23 and is filtered by the filter box 23 to reduce impurities from clogging the pipes. The filtered water is then transported to the expansion water storage bag 2 for storage by the second water pump 25.

[0045] A connecting component for monitoring water level and conveying accumulated water is connected between the conveying component and the expansion water storage bag 2. The connecting component includes a first pipe body 28, on one side of which a water pressure detector 18 is installed. One end of the first pipe body 28 is connected to a control valve 19, and the end of the control valve 19 away from the first pipe body 28 is connected to the interior of the water storage tank 15. The first pipe body 28 is a retractable flexible pipe. The water entering the expansion water storage bag 2 will also come into contact with the water pressure detector 18 on the first pipe body 28. In this way, the water pressure detector 18 can detect the water pressure inside the first pipe body 28 and the expansion water storage bag 2. By detecting the water pressure, the outflow rate is determined. After the rate reaches a preset value, the control valve 19 is opened, and the water inside the expansion water storage bag 2 flows to the water storage tank 15 and is then pumped away by the first water pump 16.

[0046] The end of the first pipe 28 away from the control valve 19 is connected to the bottom of the expansion water storage bag 2 near the water storage tank 15. A series pipe 20 is connected in series between the bottoms of the expansion water storage bags 2. A valve 21 is installed on the surface of the series pipe 20. By opening the valve 21, multiple sets of expansion water storage bags 2 can be connected to each other, and the water storage capacity can be increased according to the water accumulation in the well.

[0047] A support plate 22 is hinged to the top of the support frame 8 on the side furthest from the water tank 15. One side of the support plate 22 is in contact with the surface of the frame 3 on the side furthest from the water tank 15. By setting up the support plate 22, when multiple sets of expansion water bags 2 are used simultaneously, the support plate 22 can be flipped up to provide space for the expansion of the expansion water bags 2 and facilitate the movement of the frame 3. When the expansion water bags 2 are not in use, the top of the support frame 8 can be covered by the support plate 22. One end of the support frame 8 can also be used to limit multiple sets of frames 3, compressing the temporarily unused expansion water bags 2 together, thus saving underground space. After the support plate 22 is laid flat, the top of the support plate 22 can also be easily stepped over by underground workers, facilitating underground traffic and the flow of personnel and materials, and improving convenience.

[0048] Rivet assemblies for stabilizing and positioning the base 1 are installed on both the front and rear sides of the top. The bottom of the rivet assembly slides through the base 1 and extends to the outside of the base 1. The rivet assembly includes a rivet rod 26, which is slidably inserted into the front and rear sides of the base 1. A block 27 is installed on the top of the rivet rod 26. By pressing down on the block 27, the rivet rod 26 is driven into the underground surface, which can restrain the base 1, improve its stability, and prevent it from tipping over.

[0049] Example 2

[0050] An automatic water dispensing system operation method includes the following steps:

[0051] S1. Install a retractable water storage structure in a relatively spacious area within the main roadway, and connect the pipes used to drain the underground water to the outside of the wellhead to the water storage structure.

[0052] S2. Lay branch pipes for transporting water at water accumulation points in each sub-lane, and extend the branch pipes to connect them to the water storage structure.

[0053] S3. Install a measuring structure on the water storage structure for measuring water level and water pressure;

[0054] S4. The accumulated water in each sub-tunnel is transported to the water storage structure in the main tunnel. The water storage structure can expand and contract according to the current accumulated water volume to make reasonable use of space. After the water storage volume is measured by the measuring structure to reach the preset value, the drainage structure is activated to discharge the water in the water storage structure.

[0055] By implementing the above steps, the accumulated water in each sub-tunnel can be stored in a unified and centralized manner. Then, by observing the total amount of water after collection, a corresponding water pumping plan can be formulated, such as the number of pumps to be used, the drainage time, and how to arrange the drainage water volume. This allows for a scientific approach, making it less likely for any oversight to occur in any part of the water pumping process, and improving the efficiency of underground water pumping.
