Description
Technical Field
[0001] The invention relates to the technical field of water conservancy project crushing, in particular to debris crushing and waterlogging drainage equipment for water conservancy projects. Background Art
[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and valuable resource for human production and life, but its natural state does not fully meet human needs. Water pumps are a type of urban drainage equipment. Water pumps are machines that transport liquids or increase the pressure of liquids. They transfer the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid.
[0003] In the prior art, for floods or rainwater in water conservancy facilities or cities, it is necessary to transport water from relatively low-lying areas to relatively high areas through drainage pump stations. The drainage pump stations can be buried in relatively low-lying areas, and more debris will be mixed in the water flow, and the size of the debris is large. At the very least, the water inlet will be blocked, making the water flow speed at the water inlet relatively slow. At worst, algae branches and leaves will entangle the inside of the pump, causing damage to the pump. Therefore, these debris can easily block the submersible pump, reducing the drainage effect of the pump station. Summary of the invention
[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions: a debris crushing and drainage device for water conservancy projects, comprising a bottom plate, a connecting piece is fixedly connected to the top of the bottom plate, a frame is fixedly installed on the top of the bottom plate, a shell is fixedly installed on the top of the frame, a motor is fixedly connected to the outside of the shell, the output end of the motor passes through the shell, and a filter plate is arranged inside the shell; A limit assembly, which is fixedly mounted inside the housing and is located at one end of the housing away from the connecting piece; A crushing assembly, which is fixedly mounted in the inner cavity of the shell and is fixedly connected to the output end of the motor; The shell includes a cylinder, which is fixedly mounted on a frame, a feed pipe is fixedly connected to the outside of the cylinder, a limit assembly is located inside the feed pipe, and a discharge pipe is fixedly connected to one end of the cylinder away from the feed pipe. When the equipment is working, water and debris enter the inside of the cylinder through the feed pipe, and the motor is connected to an external power supply to work, the motor drives the shaft to rotate, and the shaft drives the outer fixed plate to rotate, so that the inclined groove on the outer side of the fixed plate engages with the convex strip on the spring plate, thereby crushing the debris and preventing the debris from directly entering the drainage equipment and causing equipment failure. The discharge pipe is away from the cylinder. One end of the spring plate is fixedly connected to the connecting piece, and a spring plate is fixedly connected to the inside of the cylinder. The spring plate contacts the outer side of the crushing assembly. The elastic deformation of the spring plate can make the contact between the crushing assembly and the material softer, reducing the direct friction and wear between the two. When there are some particles with high hardness or sharpness in the material, the spring plate can reduce the scratching and wear of these particles on the surface of the crushing assembly to a certain extent, maintain the flatness and roughness of the surface of the crushing assembly, thereby ensuring the crushing performance and service life of the crushing assembly. The end of the spring plate away from the inner wall of the cylinder is fixedly connected with a convex strip; The crushing assembly includes a rotating shaft, which is fixedly connected to the output end of the motor. A fixed plate is fixedly connected to the outer side of the rotating shaft. An inclined groove is provided at the outer edge of the fixed plate. The inclined groove and the convex strips are arranged alternately. The fixed plate and the convex strips will produce additional shearing and squeezing effects on the material, which can more effectively destroy the structure of the material and crush it into smaller particles, thereby improving the crushing efficiency and quality. At the same time, by setting the inclined groove, a complex flow direction is formed during the crushing process, breaking the agglomeration state of the material and reducing the accumulation and blockage of the material in the crushing area. Under the guidance of the convex blocks, the material constantly changes direction and speed, and can pass through the crushing area more smoothly, thereby improving the continuous operation capacity of the equipment.
[0005] Preferably, a side of the barrel close to the discharge pipe is fixedly connected to the filter plate, and the filter plate is provided to screen the crushed debris, preventing the debris from directly entering the equipment without being crushed, thereby improving the crushing effect of the crushing assembly on the debris, and the filter plate is located at the connecting part of the barrel and the discharge pipe. There are two spring plates, which are respectively arranged on the inner sides close to the feed pipe and the discharge pipe. A ball is fixedly connected to the end of the spring plate away from the barrel, and the rotating shaft drives the fixed plate to rotate, and extrusion is generated between the fixed plate and the spring plate. The spring plate is deformed by force and moves toward the direction close to the barrel, so that the balls on the spring plates on both sides contact the filter plate and the limit assembly respectively. With the rotation of the rotating shaft and the elastic performance of the spring plate, the balls reciprocate and knock on the filter plate to avoid blockage, and the end of the spring plate away from the barrel contacts the crushing assembly.
[0006] Preferably, a protrusion is fixedly connected to the outer side of the rotating shaft, a through hole is opened on the fixing plate near the middle of the rotating shaft, the protrusion is located inside the through hole, the rotating shaft is fixedly connected to the fixing plate through the cooperation between the protrusion and the through hole, a trapezoidal groove is opened on the outer side of the fixing plate, there are multiple trapezoidal grooves, and the multiple trapezoidal grooves are evenly distributed with the rotating shaft as the center, a limiting cylinder is fixedly connected to the middle of the outer side of the fixing plate, and the inner wall of the limiting cylinder contacts the outer wall of the rotating shaft. Since there are leaves and branches in the debris, the branches usually have certain flexibility and elasticity, their shapes are irregular and their surfaces may not be smooth. During the crushing process, the branches are easily crushed after being subjected to the force of the crushing equipment. The ring is connected to the outer surface of the cylinder and the debris is crushed by the blade on the outer side of the cylinder to prevent the entangled branches from occupying the crushing space and reducing the amount of material and debris. The effective contact area between the components leads to a poor crushing effect, thereby reducing the crushing efficiency. The outer end of the limiting cylinder close to the fixed plate is fixedly connected to the limiting block. There are two limiting blocks, which are symmetrically arranged with the limiting cylinder as the center. A circular ring is rotatably connected to the outer side of the limiting cylinder. The circular ring is fixedly connected to the outer side of the limiting block close to the limiting block. There are two fixed blocks, which are symmetrically arranged with the limiting cylinder as the center. The circular ring and the limiting cylinder are clamped and adapted through the limiting block and the fixed block. A circular plate is fixedly connected to the outer side of the circular plate. A blade is fixedly connected to the side of the circular plate. The blade is tilted and arranged on the side of the circular plate. The end of the circular ring away from the fixed plate is fixed. A spring is fixedly connected, and there are multiple fixed plates. The multiple fixed plates are arranged in the axial direction of the rotating shaft. The end of the spring away from the circular ring is fixedly connected to the fixed plate, and the spring is located in the middle of the two fixed plates. A trapezoidal block is fixedly connected to the end of the circular plate away from the fixed plate. The circular plate contacts the fixed plate on the other side as the rotating shaft rotates. At this time, the trapezoidal block is located inside the trapezoidal groove, and the fixed plate drives the circular plate to rotate slightly. At this time, the blade exerts axial and radial forces on the outer debris, thereby improving the cutting effect on the entangled debris. There are multiple trapezoidal blocks, and the multiple trapezoidal blocks are evenly distributed with the rotating shaft as the center, and the trapezoidal block and the trapezoidal groove are located on the same straight line.
[0007] Preferably, the limiting assembly includes a connecting plate, which is fixedly installed on the inner wall of the feed pipe. There are multiple connecting plates, which are evenly distributed around the feed pipe. One end of the connecting plate away from the cylinder is fixedly connected to a round rod, and a fixing rod is provided at the axis of the feed pipe. Water flows into the interior of the feed pipe and flows along the spiral plate. The spiral plate guides the water flow along the spiral channel to cause the water flow to produce a rotating motion, thereby reducing the friction resistance between the water flow and the pipe wall, allowing the water flow to pass more smoothly. At the same time, the spiral plate can improve the water delivery capacity without increasing the pipe diameter, thereby speeding up the drainage speed and more effectively coping with the large amount of water accumulation caused by extreme weather such as heavy rain. By arranging the spiral plate, the accumulation of debris in the drainage pipe can be reduced, the water flow resistance can be reduced, and the drainage system can be improved. Water efficiency, when the rotating shaft drives the fixed plate to rotate, the spring plate is forced to move the ball, so that the ball contacts the fixed rod. Under the action of force, the fixed rod drives the spiral plate to move upward on the round rod through the positioning block. At this time, the spacing between the spiral plates becomes larger, and the friction resistance between the water flow and the spiral plates and inside the water flow will be reduced accordingly, so that more water can flow through the drainage system, which improves the flow rate and speed of drainage and enhances the ability of the drainage system to cope with a large amount of accumulated water, so that the flow rate of the water flow in the feed pipe can be adjusted according to the speed of the motor. A spiral plate is arranged on the outside of the fixed rod, and a fixing frame is fixedly connected to one end of the connecting plate close to the round rod, and an end of the spiral plate close to the cylinder is fixedly connected to the fixing frame. The round rod is slidably connected to the edge of the spiral plate, and a positioning block is fixedly connected to the top of the fixed rod, and the positioning block is fixedly connected to the end of the spiral plate.
[0008] The present invention provides a debris crushing and waterlogging drainage device for a water conservancy project. It has the following beneficial effects: 1. The debris crushing and drainage equipment of the water conservancy project drives the outer fixed plate to rotate through the rotating shaft, so that the inclined groove on the outer side of the fixed plate and the convex strip on the spring plate engage with each other, thereby crushing the debris and preventing the debris from directly entering the drainage equipment and causing equipment malfunction.
[0009] 2. The debris crushing and drainage equipment of the water conservancy project can make the contact between the crushing component and the material softer by utilizing the elastic deformation of the spring plate, reducing the direct friction and wear between the two. When there are some hard or sharp particles in the material, the spring plate can reduce the scratching and wear of these particles on the surface of the crushing component to a certain extent, maintain the flatness and roughness of the surface of the crushing component, thereby ensuring the crushing performance and service life of the crushing component.
[0010] 3. The debris crushing and drainage equipment of the water conservancy project moves on the outside of the limit cylinder toward the side away from the limit block through the circular ring, so that the circular ring drives the circular plate to move. At this time, the blade on the outside of the circular plate crushes the debris wrapped around the outside of the crushing component to prevent the wrapped branches from occupying the crushing space and reduce the effective contact area between the material and the crushing component.
[0011] 4. The debris crushing and drainage equipment of the water conservancy project will guide the water flow along the spiral channel through the spiral plate, causing the water flow to rotate, thereby reducing the friction resistance between the water flow and the pipe wall, allowing the water flow to pass more smoothly, reducing the accumulation of debris in the drainage pipe, reducing water flow resistance, and thus improving the drainage efficiency of the drainage system.

The motor 5 drives the rotating shaft 71 to rotate, and the rotating shaft 71 drives the outer fixed plate 73 to rotate, so that the inclined groove 74 on the outer side of the fixed plate 73 and the convex strip 45 on the spring plate 44 are engaged with each other, so as to crush the debris and prevent the debris from directly entering the interior of the drainage equipment, causing equipment failure. The end of the discharge pipe 43 away from the cylinder 41 is fixedly connected to the connecting piece 2, and a spring plate 44 is fixedly connected to the inside of the cylinder 41, and the spring plate 44 contacts the outer side of the crushing assembly 7. The elastic deformation of the spring plate 44 can make the contact between the crushing assembly 7 and the material softer, reducing the direct friction and wear between the two. When there are some particles with high hardness or sharpness in the material, the spring plate can reduce the scratching and wear of these particles on the surface of the crushing assembly 7 to a certain extent, maintain the flatness and roughness of the surface of the crushing assembly 7, thereby ensuring the crushing performance and service life of the crushing assembly 7.

A fixed plate 73 is fixedly connected to the outer side of the rotating shaft 71. An inclined groove 74 is provided at the outer edge of the fixed plate 73. The inclined groove 74 and the convex strips 45 are arranged alternately. The fixed plate 73 and the convex strips 45 will produce additional shearing and squeezing effects on the material, which can more effectively destroy the structure of the material and crush it into smaller particles, thereby improving the crushing efficiency and quality. At the same time, by setting the inclined groove 74, a complex flow direction is formed during the crushing process, breaking the agglomeration state of the material and reducing the accumulation and blockage of the material in the crushing area. Under the guidance of the protrusions, the material constantly changes direction and speed, and can pass through the crushing area more smoothly, thereby improving the continuous operation capacity of the equipment.
[0016] The second embodiment is based on the first embodiment. Figures 5 to 9 As shown, one side of the cylinder 41 close to the discharge pipe 43 is fixedly connected to the filter plate 8. By setting the filter plate 8, the crushed debris is screened to prevent the debris from directly entering the equipment without being crushed, thereby improving the crushing effect of the crushing component 7 on the debris, and the filter plate 8 is located at the connection between the cylinder 41 and the discharge pipe 43.

The spring plate 44 is deformed by force and moves toward the direction close to the cylinder 41, so that the balls 46 on the spring plates 44 on both sides contact the filter plate 8 and the limit assembly 6 respectively. With the rotation of the rotating shaft 71 and the elastic performance of the spring plate 44, the balls 46 reciprocate and knock on the filter plate 8 to avoid blockage.

Since there are leaves and branches in the debris, the branches usually have a certain degree of flexibility and elasticity, and their shapes are irregular and their surfaces may not be smooth. During the crushing process, the branches are easily bent and twisted after being subjected to the force of the crushing equipment. , and then entangled with each other, the water flow and debris enter the interior of the cylinder 41 through the feed pipe 42, the motor 5 is connected to an external power supply to work, the motor 5 drives the rotating shaft 71 to rotate, the rotating shaft 71 drives the fixing plate 73 to rotate, the fixing plate 73 drives the limiting cylinder 711 and the limiting block 712 to rotate, the limiting block 712 rotates on the side of the ring 713 close to the fixing plate 73, when the limiting block 712 contacts and squeezes the fixing block 714, under the action of pressure, the spring 710 is deformed and compressed by the force, so that the ring 713 moves on the outside of the limiting cylinder 711 toward the side away from the limiting block 712, so that the ring 713 drives the circular plate 77 to move, and at this time, the outer blade 78 of the circular plate 77 crushes the debris entangled on the outside of the crushing assembly 7 to prevent the entangled branches from occupying the crushing space.
