Description

Technical Field

[0001] The invention relates to the technical field of fluid driving, in particular to a multi-pump water pumping device for a mine hole. Background Art

[0002] In the process of underground coal mining, due to the outburst of water in the stratum, the infiltration of rainwater and river water, water-sand filling and underground water supply of hydraulic coal mining mines, a large amount of water will be collected in the mine day and night, so it is necessary to use a water pump to pump out the collected water in the mine; at present, impeller-type water pumps are commonly used in mines. The principle is to use the rotating motion of the impeller to generate centrifugal force, so that the liquid generates pressure, and then it is transported to the required place through the pipeline. During the working process of the water pump, the water flowing in the pump is subject to friction with the flow channel and the surface of the pump impeller, and as the pumping height increases, the reaction force of the water body on the impeller becomes larger, and the efficiency of the water pumping is greatly reduced. For this reason, we propose a mine hole multi-pump water pumping equipment to solve the above technical problems. Summary of the Invention

[0039] As a preferred solution of the present invention, lubricant is applied to the outer wall of the rubber tube and the outer wall of the roller.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. In the present invention, the roller rolls upward along the outer wall of the rubber tube to pump the water inside the rubber tube upward. The water pressure inside the rubber tube increases, which opens the left and right clamps, so that the left and right clamps push the slide bar 2 to slide along the inside of the linear bearing 2, compressing the spring 2 to store force. After the two clamps are opened, the water inside the rubber tube can pass through the rubber tube in the area between the two clamps and be pumped upward. As the rotating block continues to rotate, the left and right rollers rolling the rubber tube gradually stop squeezing the rubber tube. At this time, the water pressure inside the rubber tube decreases, and the rebound force of the spring 2 is released, so that the left and right clamps squeeze the outer wall of the rubber tube toward the middle again, and the inner walls thereof fit together. The conduction inside the rubber tube is interrupted, and the water pumped upward before cannot flow back downward. The water pumping efficiency is not affected by the pumping height, and the overall water pumping efficiency is stable.

[0042] 2. In the present invention, when the rubber tube is clamped in the middle by the two clamps, the sliding rod 2 is driven to move in the direction of the rubber tube, so that the sliding rod 2 drives the piston to slide in the opposite direction along the inner wall of the air cylinder, resulting in negative pressure inside the air cylinder, and through the connection of the elbow 1, the air pipe and the elbow 2, the air inside the pump casing is sucked, resulting in negative pressure inside the pump casing. In other words, the outside of the rubber tube is a negative pressure environment, so that after the roller rolls the rubber tube, the rubber tube can quickly recover under the action of the external negative pressure, and negative pressure will be generated inside the rubber tube during the recovery process, which can improve the efficiency of water collection inside the mine into the rubber tube, and indirectly improve the water pumping efficiency.

[0043] 3. In the present invention, after the left and right rollers come into contact with the outer wall of the rubber tube, as the rotating block rotates, the rollers are subjected to a reaction force to push the slide bar 1 to slide along the inside of the linear bearing 1, causing the spring 1 to compress and store force. When the slide bar 1 rotates to a horizontal angle as the rotating block rotates, the sliding stroke value of the slide bar 1 is the largest. Thereafter, as the rotating block and the rollers continue to rotate, the rebound force of the spring 1 pushes the slide bar 1 to slide in the opposite direction along the inside of the linear bearing 1, thereby pushing the rollers to close to the outer wall of the rubber tube under the connection action of the adapter bracket, so that the rollers roll along the outer wall of the rubber tube for a longer stroke and the water pumping efficiency is higher.

[0055] See also Figures 1 to 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0056] A mine borehole multi-pump water pumping equipment includes a pumping unit 100, a non-return unit 200 and an air extraction unit 300. The pumping unit 100 is used for pumping water. The non-return unit 200 is fixedly arranged on the top of the pumping unit 100 and is used for pumping non-return. The air extraction unit 300 is fixedly arranged on the left and right sides of the non-return unit 200 and is used for resetting the pumping unit 100.

[0057] For further details, please refer to Figures 3 to 7 As shown:

[0058] The pumping unit 100 includes a pump housing 101, a rubber tube 102, a rotating block 103, a rotating shaft 104, a linear bearing 105, a slide rod 106, an adapter bracket 107, a roller 108, a spring 109, a driven synchronous wheel 1010, a gear box 1011, a driving synchronous wheel 1012, a synchronous belt 1013 and a power motor 1014. The pump housing 101 is fixed by the bottom support legs, the rubber tube 102 is fixedly set inside the pump housing 101, and the rotating block 103 is rotatably set inside the pump housing 101, and is symmetrically divided into two parts. There are two rotating blocks 103, which are distributed on the left and right sides of the rubber tube 102. The rotating shaft 104 is fixedly installed at the front and rear ends of the rotating block 103. The rotating shaft 104 is rotatably connected to the side wall of the pump housing 101 through a sealed bearing. The linear bearing 105 is symmetrically distributed about the diagonal line of the rotating block 103 and is fixed on the surface of the rotating block 103. The linear bearing 105 is divided into two parts, the front and rear. The slide rod 106 is slidably installed inside the linear bearing 105. The adapter bracket 107 is fixedly installed on the slide rod 106 away from the linear bearing 10 5, the roller 108 is rotatably mounted between the front and rear adapter brackets 107, the spring 109 is sleeved on the periphery of the slide rod 106, and is fixedly mounted between the adapter bracket 107 and the linear bearing 105, the driven synchronous wheel 1010 is fixedly mounted on the outer wall of one of the rotating shafts 104 away from the end of the rotating block 103, the gear box 1011 is fixedly mounted on the front of the pump housing 101, the active synchronous wheel 1012 is fixedly mounted on the left and right output shafts of the gear box 1011, and the synchronous belt 1013 is sleeved on the driven synchronous wheel 101 0 and the active synchronous wheel 1012, there are two synchronous belts 1013, which are distributed on the left and right. The power motor 1014 is fixedly installed on the upper front part of the pump casing 101, and the end of its output shaft is fixedly connected to the top input shaft of the gear box 1011 through a coupling. A water inlet 1015 is opened through the bottom of the pump casing 101, and the bottom of the rubber tube 102 is fixedly connected to the top of the water inlet 1015. A filter is fixedly set inside the water inlet 1015, and the outer wall of the rubber tube 102 and the outer wall of the roller 108 are coated with lubricant.

[0059] Specifically, by placing this device in a mine, the collected water in the mine enters the rubber tube 102 through the water inlet 1015, and the output shaft of the power motor 1014 drives the input shaft of the gear box 1011 to rotate, and then the two output shafts of the gear box 1011 rotate in opposite directions, and drive the left and right active synchronous wheels 1012 to rotate in opposite directions together. The two active synchronous wheels 1012 further drive the left and right driven synchronous wheels 1010 to rotate together through the left and right synchronous belts 1013, so that the left and right rotating shafts 104 and the left and right rotating blocks 103 rotate in opposite directions. The rotation of the rotating block 103 drives the roller 108 to rotate together through the connection of the linear bearing 105, the slide bar 106 and the adapter bracket 107, squeezing the outer wall of the rubber tube 102, and the roller 108 rolls upward along the outer wall of the rubber tube 102. The water inside the rubber tube 102 is pumped upward by pressure. It should be noted that after the left and right rollers 108 come into contact with the outer wall of the rubber tube 102, as the rotating block 103 rotates, the roller 108 is subjected to the reaction force to push the slide bar 106 to slide along the inside of the linear bearing 105, causing the spring 109 to compress and accumulate force. When the slide bar 106 rotates to a horizontal angle with the rotating block 103, the sliding stroke value of the slide bar 106 is the largest. Thereafter, as the rotating block 103 and the roller 108 continue to rotate, the rebound force of the spring 109 pushes the slide bar 106 to slide in the opposite direction along the inside of the linear bearing 105, thereby pushing the roller 108 close to the outer wall of the rubber tube 102 under the connection action of the adapter bracket 107, so that the roller 108 rolls along the outer wall of the rubber tube 102 for a longer distance and the water pumping efficiency is higher.

[0060] For further details, please refer to Figure 8 、 Figure 9 As shown:

[0061] The anti-return unit 200 includes an upper shell 201, a drain outlet 202, a linear bearing 203, a slide rod 204, a chuck 205 and a spring 206. The upper shell 201 is fixedly installed on the top of the pump casing 101, and the rubber tube 102 extends to the inside of the upper shell 201. The drain outlet 202 is opened through the top of the upper shell 201. The top of the rubber tube 102 is fixedly connected to the bottom of the drain outlet 202. The linear bearing 203 is distributed front and back and fixedly installed on the left and right sides of the upper shell 201. The slide rod 204 is slidably installed inside the linear bearing 203. The chuck 205 is fixedly installed on the front and rear two slide rods 204 near one end of the rubber tube 102. There are two chucks 205. The spring 206 is sleeved on the outer periphery of the slide rod 204 and fixedly installed between the inner wall of the upper shell 201 and the chuck 205.

[0062] Specifically, the roller 108 rolls upward along the outer wall of the rubber tube 102 to pump the water inside the rubber tube 102 upward, and the water pressure inside the rubber tube 102 increases, which opens the left and right clamps 205, so that the left and right clamps 205 push the slide bar 204 to slide along the inside of the linear bearing 203, and the compression spring 206 accumulates force. After the two clamps 205 are opened, the water inside the rubber tube 102 can pass through the rubber tube 102 in the area between the two clamps 205, and thus be pumped upward. As the rotating block 103 continues to rotate, the left and right sides of the rubber tube 102 are rolled. The roller 108 then gradually stops squeezing the rubber tube 102. At this time, the water pressure inside the rubber tube 102 decreases, and the rebound force of the second slide bar 204 is released, so that the left and right clamps 205 squeeze the outer wall of the rubber tube 102 toward the middle again, causing the rubber tube 102 to collapse and its inner walls to fit together. The conduction inside the rubber tube 102 is interrupted, that is, the water previously pumped upward cannot flow back downward. As the rotating block 103 continues to rotate, the above process is repeated, and the collected water inside the mine is pumped upward. The water pumping efficiency is not affected by the pumping height, and the overall water pumping efficiency is stable.

[0063] For further details, please refer to Figure 8 、 Figure 9 As shown:

[0064] The air extraction unit 300 includes an air cylinder 301, a piston 302, an elbow 1 303 and an elbow 2 304. The air cylinder 301 is fixedly mounted on the left end and the right end of the top of the pump housing 101. The position of the air cylinder 301 corresponds to the position of the slide bar 204. The piston 302 is fixedly mounted on the outer wall of the slide bar 204 away from the end of the chuck 205, and its outer wall is slidably connected to the inner wall of the air cylinder 301. The elbow 1 303 is fixedly mounted on the end of the air cylinder 301 away from the upper housing 201. The interior of elbow 1 303 is connected to the interior of the air cylinder 301, and an air pipe 305 is fixedly connected between elbow 2 304 and elbow 1 303. Two threaded holes 1017 distributed front and back are penetrated at the top left end and the top right end of the pump housing 101. The elbow 2 304 is screwed into the inside of the threaded hole 1017. A one-way air guide valve 306 is fixedly installed at one end of the top of the air cylinder 301 near elbow 1 303, and the interior of the one-way air guide valve 306 is connected to the interior of the air cylinder 301.

[0065] When the two clamps 205 are stretched open by the rubber tube 102, the second slide bar 204 moves away from the rubber tube 102 and drives the piston 302 to slide along the inside of the cylinder 301, compressing the air inside the cylinder 301 and discharging the air inside the cylinder 301 through the one-way air guide valve 306. When the two clamps 205 clamp the rubber tube 102 toward the middle, the second slide bar 204 is driven to move toward the rubber tube 102, so that the second slide bar 204 drives the piston 302 to slide in the opposite direction along the inner wall of the cylinder 301, resulting in negative pressure inside the cylinder 301, and through the connection of the elbow 1 303, the air pipe 305 and the elbow 2 304, the air inside the pump housing 101 is sucked, resulting in negative pressure inside the pump housing 101. That is, the outside of the rubber tube 102 is a negative pressure environment, so that after the roller 108 rolls the rubber tube 102, The rubber tube 102 can recover quickly under the action of external negative pressure, and negative pressure will be generated inside the rubber tube 102 during the recovery process, which can improve the efficiency of water collection inside the mine into the rubber tube 102, indirectly improving the water pumping efficiency.

[0066] The present invention relates to a multi-pump water pumping device for a mine hole. When the device is in operation, the device is placed in the mine. The collected water in the mine enters the rubber tube 102 through the water inlet 1015, and the output shaft of the power motor 1014 drives the input shaft of the gear box 1011 to rotate. Then, the two output shafts of the gear box 1011 rotate in opposite directions, and drive the left and right active synchronous wheels 1012 to rotate in opposite directions together. The two active synchronous wheels 1012 further drive the left and right driven synchronous wheels 1010 to rotate together through the left and right synchronous belts 1013, so that the left and right rotating shafts 104 and the left and right rotating blocks 103 rotate in opposite directions. The rotation of the rotating block 103 drives the roller 108 to rotate together through the connection of the linear bearing 105, the slide bar 106 and the adapter bracket 107, squeezing the outer wall of the rubber tube 102, and the roller 108 rolls upward along the outer wall of the rubber tube 102 to pump the water inside the rubber tube 102 upward. The water pressure inside the rubber tube 102 increases, and the left and right clamps 205 are stretched open. The two clamps 205 on the left and right push the slide bar 204 to slide along the inside of the linear bearing 203, and the compression spring 206 accumulates force. After the two clamps 205 are stretched open, the water inside the rubber tube 102 can pass through the rubber tube 102 in the area between the two clamps 205, and is pumped upward. As the rotating block 103 continues to rotate, the left and right rollers 108 that roll the rubber tube 102 gradually stop squeezing the rubber tube 102. At this time, the water pressure inside the rubber tube 102 becomes smaller, and the rebound force of the slide bar 204 is released, so that the left and right clamps 205 squeeze the outer wall of the rubber tube 102 toward the middle again, causing the rubber tube 102 to collapse and its inner walls to fit together. The conduction inside the rubber tube 102 is interrupted, that is, the water pumped upward before cannot flow back downward, so as the rotating block 103 continues to rotate, the above process is repeated, and the collected water inside the mine is pumped upward. The pumping efficiency is not affected by the pumping height, and the overall pumping efficiency is stable.

[0067] When the two clamps 205 are stretched open by the rubber tube 102, the second slide bar 204 moves away from the rubber tube 102 and drives the piston 302 to slide along the inside of the cylinder 301, compressing the air inside the cylinder 301 and discharging the air inside the cylinder 301 through the one-way air guide valve 306. When the two clamps 205 clamp the rubber tube 102 toward the middle, the second slide bar 204 is driven to move toward the rubber tube 102, so that the second slide bar 204 drives the piston 302 to slide in the opposite direction along the inner wall of the cylinder 301, resulting in negative pressure inside the cylinder 301, and through the connection of the elbow 1 303, the air pipe 305 and the elbow 2 304, the air inside the pump housing 101 is sucked, resulting in negative pressure inside the pump housing 101. That is, the outside of the rubber tube 102 is a negative pressure environment, so that after the roller 108 rolls the rubber tube 102, The rubber tube 102 can recover quickly under the action of external negative pressure, and negative pressure will be generated inside the rubber tube 102 during the recovery process, which can improve the efficiency of water collection inside the mine into the rubber tube 102, indirectly improving the water pumping efficiency.

[0068] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
