Description

Technical Field

[0001] The invention relates to the technical field of coal mine water tanks, and in particular to a coal mine water tank with a sludge measuring function. Background Art

[0002] The main functions of coal mine water tanks include storing and regulating mine water, settling silt, and ensuring the normal operation of drainage equipment during cleaning. Coal mine water tanks, especially main water tanks, are usually composed of two independent tunnels with the same cross-section, located below the level of the pit bottom parking lot. There are a large number of solid particulate matter in the mine water. When the coal mine water tank is used for long-term sedimentation, a large amount of silt will accumulate at the bottom of the coal mine water tank. A large amount of silt will cause the water storage capacity inside the coal mine water tank to decrease, so staff are required to regularly measure and clean the silt at the bottom of the coal mine water tank.

[0003] Common silt measuring devices at the bottom of coal mine silos are used by directly inserting the measuring detection rod into the silt, and detecting the thickness of the silt according to the length of the detection rod buried in the silt. However, its effect is relatively simple during use and can only be used for silt quantity detection. When the detection equipment completes the silt quantity detection and performs silt cleaning, the detection equipment cannot be used to clean the silt or play a good auxiliary role in cleaning the silt. Summary of the invention

[0006] Preferably, a groove is provided on the bottom of the protective plate near the placement groove, the groove is connected to the interior of the placement groove, a first connecting plate is installed on the side of the fixed plate near the protective plate, the first connecting plate is connected to the discharge hole, and funnel-shaped drainage holes are provided at both ends of the top of the fixed plate on the side of the protective plate.

[0007] Preferably, second connecting plates are installed at both ends of the top of the fixing plate, one end of the second connecting plate is installed on the side of the protective plate, the drainage hole and the placement groove are located between the two second connecting plates, and fixing holes are opened at both ends of the side of the second connecting plate.

[0008] Preferably, the bottom opposite surfaces of the two lifting plates are provided with support grooves, the bottom side surfaces of the lifting plates are provided with screw holes matching the fixing holes, and support rods are installed at both ends of the fixing plates, which are rotatably installed inside the support grooves.

[0009] Preferably, a placement hole is formed at one end of the mounting plate away from the inner wall of the mounting groove, the placement hole is connected to the sliding hole, and a support plate is installed on the side of the placement hole at the end of the mounting plate away from the inner wall of the mounting groove.

[0010] Preferably, the opposing surfaces of the two lifting plates are provided with a plurality of tooth grooves in the length direction, a motor is installed on the side of the support plate away from the placement hole, the output shaft of the motor passes through the support plate and is installed with a gear, one end of the gear passes through the placement hole and is meshed with the tooth groove.

[0011] Preferably, a guide groove is provided at the inner bottom of the installation groove in the length direction, an electric slider is slidably installed inside the guide groove, and one end of the installation plate located inside the installation groove is installed on the top of the electric slider.

[0012] Preferably, baffles are installed at the inner bottom of one end of the bin body near the inner walls on both sides, and limiting holes are provided on the sides of the baffles, and the baffles are located above the sides of the fixed plate.

[0013] Preferably, fixing bolts matching the fixing holes are installed on the opposite surfaces of the two second connecting plates, and one end of the fixing bolt passes through the fixing hole and is threadedly installed in the screw hole.

[0014] Preferably, a side of the lifting plate away from the fixed plate abuts against an inner wall of the bin body, and two ends of the fixed plate abut against opposite surfaces of the two lifting plates respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the fixed plate in the present invention moves downward toward the bottom of the bin body in the water, the water inside the bin body will exert a certain resistance on the bottom of the fixed plate, and the pressure detection piece located at the bottom of the fixed plate can detect the pressure on the bottom of the fixed plate in real time. When the bottom of the fixed plate contacts the silt at the bottom of the bin body, the silt increases the downward resistance of the fixed plate, and the pressure detected by the pressure detection piece will also increase. The staff outside can detect the height of the silt at the bottom of the bin body according to the pressure intensity exerted on the pressure detection piece, which is convenient for the staff to measure the height of the silt at the bottom of the bin body.

[0016] 2. In the present invention, when the staff needs to temporarily clean part of the sludge at the bottom of the bin body, the motor can drive the fixed plate to move down to the inside of the sludge, so that the sludge enters the placement groove on the top of the fixed plate, and the motor drives the fixed plate to move up slowly through the lifting plate until the upward movement level of the fixed plate is above the horizontal height of the baffle plate, and the position of the conveying pipe close to the first connecting plate is higher than the position close to the baffle plate, the sludge inside the placement groove can flow to the inside of the conveying pipe through the discharge hole, and the sludge is conveyed to the designated position through the conveying pipe. When in use, the staff can temporarily clean part of the sludge inside the bin body, and when in use, the staff can drive the fixed plate to move its position through the electric slider, so that the staff can clean the sludge at different positions on the bottom of the bin body conveniently.

[0017] 3. In the present invention, when the staff needs to completely clean the silt at the bottom of the bin body, the staff discharges the water at the bottom of the bin body in advance, and rotates the fixing plate by removing the fixing bolts. The motor drives the fixing plate to move downward, so that the side of the fixing plate away from the protective plate enters into the silt. When there is too much silt at the bottom of the bin body, the side of the fixing plate away from the protective plate enters into the silt, and the protective plate is located above the silt. When there is less silt at the bottom of the bin body, the end of the fixing plate away from the protective plate abuts against the inner bottom of the bin body, and the electric slider drives the fixing plate to move in the direction of the baffle, and the fixing plate can push the silt to a position close to the baffle when moving, which is convenient for the staff to clean the silt.

[0018] 4. When the fixed plate in the present invention moves to clean the sludge at the bottom of the bin body, the lifting plates located on both sides of the bin body can clean the inner walls on both sides of the bin body respectively. When in use, there is no need for staff to enter the bin body to manually clean the sludge, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As a technical optimization scheme of the present invention, a groove 23 is provided on the bottom of the protective plate 8 near the placement groove 22, and the groove 23 is interconnected with the interior of the placement groove 22. A first connecting plate 9 is installed on the side of the fixed plate 7 near the protective plate 8, and the first connecting plate 9 is interconnected with the discharge hole 24. Funnel-shaped drainage holes 25 are provided on the sides of the protective plate 8 at both ends of the top of the fixed plate 7; when the staff temporarily cleans the silt at the bottom of the warehouse body 1 in the water, the drainage holes 25 can discharge excess water on the top of the fixed plate 7. At the same time, when the fixed plate 7 is lifted and moved in the water, the water inside the warehouse body 1 can flow from the inside of the drainage holes 25, thereby reducing the resistance of the water to the fixed plate 7 when the fixed plate 7 is lifted and lowered.

[0025] As a technical optimization solution of the present invention, second connecting plates 14 are installed at both ends of the top of the fixing plate 7, one end of the second connecting plate 14 is installed on the side of the protective plate 8, the drainage hole 25 and the placement groove 22 are both located between the two second connecting plates 14, and fixing holes 28 are opened at both ends of the side of the second connecting plate 14; the second connecting plate 14 can be used to connect and fix the fixing plate 7 and the lifting plate 6.

[0027] As a technical optimization solution of the present invention, a placement hole 19 is opened at one end of the mounting plate 5 away from the inner wall of the mounting groove 2, the placement hole 19 is connected to the sliding hole 21, and a support plate 12 is installed on the side of the placement hole 19 at the end of the mounting plate 5 away from the inner wall of the mounting groove 2; the support plate 12 can install and protect the motor 13.

[0028] As a technical optimization scheme of the present invention, the opposite surfaces of the two lifting plates 6 are provided with a plurality of tooth grooves 18 in the length direction, and a motor 13 is installed on the side of the support plate 12 away from the placement hole 19. The output shaft of the motor 13 passes through the support plate 12 and is installed with a gear 20. One end of the gear 20 passes through the placement hole 19 and is meshed with the tooth grooves 18. The motor 13 can drive the lifting plate 6 and the fixed plate 7 to move up and down through the gear 20.

[0029] As a technical optimization solution of the present invention, a guide groove 10 is opened at the inner bottom of the installation groove 2 in the length direction, and an electric slider 11 is slidably installed inside the guide groove 10. The end of the installation plate 5 located inside the installation groove 2 is installed on the top of the electric slider 11; when in use, the electric slider 11 can drive the lifting plate 6 and the fixed plate 7 to move inside the warehouse body 1, so that the staff can measure the silt thickness at different positions inside the warehouse body 1 conveniently.

[0030] As a technical optimization solution of the present invention, baffles 3 are installed at the inner bottom of one end of the bin body 1 near the inner walls on both sides, and limiting holes 4 are provided on the sides of the baffles 3. The baffles 3 are located above the sides of the fixed plate 7. When in use, the staff can put the baffles 3 on the conveying pipe connected to the first connecting plate 9 to facilitate the position limitation of the conveying pipe.

[0031] As a technical optimization solution of the present invention, the opposite surfaces of the two second connecting plates 14 are installed with fixing bolts 16 matching the fixing holes 28, one end of the fixing bolts 16 passes through the fixing holes 28 and is threadedly installed in the screw holes 17; when in use, the staff can disassemble the fixing bolts 16 according to the usage conditions, so as to facilitate the angle adjustment of the first fixing plate 7.

[0032] As a technical optimization solution of the present invention, the side of the lifting plate 6 away from the fixed plate 7 abuts against the inner wall of the warehouse body 1, and the two ends of the fixed plate 7 abut against the opposite surfaces of the two lifting plates 6 respectively; when the lifting plate 6 moves, the lifting plate 6 can clean the inner walls on both sides of the warehouse body 1.

[0033] When the present invention is in use, the staff connects the delivery pipe for conveying sludge to the first connection plate 9, and the end of the delivery pipe away from the first connection plate 9 passes through the limiting hole 4 on the side of the baffle plate 3 and is connected to the external sludge treatment equipment. When in use, the baffle plate 3 can better limit the length of the delivery pipe inside the bin body 1 through the limiting hole 4, and at the same time limit the height of the delivery pipe at the position of the baffle plate 3.

[0034] When the staff needs to detect the silt thickness at the bottom of the warehouse body 1, the staff can drive the gear 20 to rotate inside the placement hole 19 through the motor 13. Because the gear 20 is meshed with the tooth groove 18 on the side of the lifting plate 6, when the gear 20 rotates, it can drive the lifting plate 6 to move downward, and when the lifting plate 6 moves downward, it can drive the fixed plate 7 to move toward the bottom of the warehouse body 1. When in use, a large amount of water is stored inside the warehouse body 1. When the fixed plate 7 moves downward to the bottom of the warehouse body 1 in the water, the water inside the warehouse body 1 will exert a certain resistance on the bottom of the fixed plate 7, and the pressure detection sheet 27 located at the bottom of the fixed plate 7 can detect the pressure on the bottom of the fixed plate 7 in real time.

[0035] When the fixed plate 7 moves downward in the water inside the silo 1, a part of the water below the fixed plate 7 will flow through the drainage holes 25 on the fixed plate 7, which can reduce the resistance of the fixed plate 7 when it moves downward. When the bottom of the fixed plate 7 contacts the silt at the bottom of the silo 1, the silt increases the downward resistance of the fixed plate 7, and the pressure detected by the pressure detection sheet 27 will also increase. The staff outside can detect the silt height at the bottom of the silo 1 according to the pressure on the pressure detection sheet 27, which is convenient for the staff to measure the height of the silt at the bottom of the silo 1.

[0036] When the staff needs to temporarily clean up the sludge at the bottom of the silt body 1, the staff can use the motor 13 to drive the fixed plate 7 to press down into the sludge, so that the fixed plate 7 and the protective plate 8 enter the sludge, and the electric slider 11 can drive the fixed plate 7 to move a short distance inside the sludge through the mounting plate 5 and the lifting plate 6, and as the fixed plate 7 moves, the sludge at the bottom of the silt body 1 can enter the placement groove 22 at the top of the fixed plate 7. When the staff grabs the sludge at the bottom of the silt body 1, the position of the end of the conveying pipe close to the baffle 3 is higher than the position of the first connecting plate 9, so the water and sludge inside the silt body 1 will not enter the conveying pipe.

[0037] When the fixed plate 7 finishes grabbing the sludge, the motor 13 drives the fixed plate 7 to move up slowly through the lifting plate 6 until the upward movement height of the fixed plate 7 is above the horizontal height of the baffle 3, and the position of the conveying pipe close to the first connecting plate 9 is higher than the position close to the baffle 3, and the sludge inside the placement groove 22 at the top of the fixed plate 7 can flow to the inside of the conveying pipe through the discharge hole 24, and the sludge is conveyed to the designated position through the conveying pipe. When in use, the staff can temporarily clean part of the sludge inside the bin body 1, and when in use, the staff can drive the fixed plate 7 to move its position through the electric slider 11, so that the staff can clean the sludge at different positions on the bottom of the bin body 1 conveniently.

[0038] When the staff needs to completely clean the silt at the bottom of the silo 1, the staff will drain the water at the bottom of the silo 1 in advance, and the staff will disassemble the fixing bolts 16 and rotate the fixing plate 7 so that the fixing plate 7 rotates around the support rod 26 until the fixing bolts 16 inside one of the screw holes 17 on the side of the lifting plate 6 moves to the position of the other screw hole 17 as the fixing plate 7 rotates, and the staff can fix the fixing plate 7 again through the fixing bolts 16 and the screw holes 17. When in use, the staff drives the fixing plate 7 to move downward through the motor 13 so that the side of the fixing plate 7 away from the protective plate 8 enters the inside of the silt. When there is too much silt at the bottom of the silo 1, the side of the fixing plate 7 away from the protective plate 8 enters the inside of the silt, and the protective plate 8 is located above the silt. When there is less silt at the bottom of the silo 1, the end of the fixing plate 7 away from the protective plate 8 abuts against the inner bottom of the silo 1.

[0039] The electric slider 11 drives the fixed plate 7 to move in the direction of the baffle 3, and the fixed plate 7 can push the sludge to a position close to the baffle 3 when moving, so that the staff can clean the sludge conveniently. When the fixed plate 7 moves to clean the sludge at the bottom of the warehouse body 1, the lifting plates 6 located on both sides of the warehouse body 1 can clean the inner walls of the warehouse body 1 on both sides respectively. When in use, there is no need for the staff to enter the warehouse body 1 to manually clean the sludge, which is more convenient to use.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
