Description

Technical Field

[0001] This invention relates to water conservancy engineering technology, specifically to a drainage valve used in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can water flow be controlled, floods prevented, and water volume regulated and distributed. New types of waterproof and drainage devices are needed during the construction of water conservancy projects. Drainage valves are an indispensable product in the water industry, mainly used in urban, building, and enterprise water supply and drainage projects, industrial and domestic sewage treatment, and water conservancy projects. They are primarily used for liquid discharge or liquid level control. With the development of the times, water conservancy projects are increasingly covering rivers, and drainage valves are used to control water flow rate and hydraulic pressure, playing a vital role in water conservancy projects.

[0003] Chinese invention patent CN114635390A discloses a novel waterproof and drainage device for water conservancy engineering construction. In use, water flow drives blades to rotate, which in turn drives a drive shaft. The drive shaft, through a transmission assembly, drives a driven shaft, which in turn drives a rotating cylinder. The rotating cylinder, through a vibration assembly, vibrates a filter screen, dislodging impurities from the screen to the right. The rotating cylinder, through an eccentric column, drives a cleaning assembly to rotate. The cleaning assembly, by rotating itself, extends and retracts a cleaning rod into the rotating cylinder. When the cleaning rod extends, it scrapes and cleans the rectangular filter holes on the filter screen. When the cleaning rod retracts, it removes the scraped impurities and collects them, thus preventing impurities from accumulating on the filter screen and facilitating the removal of impurities from the cleaning rod, thereby improving work efficiency.

[0004] In existing technologies, we often use drain valves in many places. However, during the use of drain valves, it is not convenient to remove floating debris and garbage, and it cannot separately discharge silt in the water. This results in insufficient functionality, causing silt to accumulate at the drain outlet, which greatly reduces the drainage efficiency. Therefore, a drain valve for water conservancy projects has been developed. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage valve for water conservancy projects to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drainage valve for water conservancy projects, comprising a main body, the front end of which is frustum-shaped, and a cleaning component provided in the inner cavity of the main body, and the cleaning component is used to treat the residue in the drainage valve;

[0007] The cleaning component includes a pressing block, the outer surface of which is slidably connected to the inner wall of the main body. A ring is fixedly installed at the lower end of the pressing block. Multiple sets of sliding grooves are formed on the outer surface of the ring. Limiting blocks are slidably installed on the inner wall of the sliding grooves. A cylinder is installed at one end of the limiting block. A first cleaning plate is fixedly installed at the lower end of the cylinder. A telescopic member is provided in the inner cavity of the ring. One end of the telescopic member passes through and extends to the outside of the first cleaning plate. A second cleaning plate is fixedly installed on the outer surface of the lower end of the telescopic member. A turbine blade is fixedly installed at the lower end of the telescopic member.

[0008] A vibration assembly is mounted on the lower end of the turbine blades, and the turbine blades drive the entire vibration assembly to rotate.

[0009] As a further optimization of the present invention, the upper end of the telescopic member is rotatably connected to the lower end of the pressing block, and the cross-section of the ring is smaller than the cross-section of the cylinder, and the inner wall of the cylinder is slidably connected to the outer surface of the ring.

[0010] As a further optimization of the present invention, a positioning block is rotatably mounted on the outer surface of the telescopic member, and the lower end of the positioning block is connected to the upper end of the first cleaning plate.

[0011] As a further optimization of the present invention, the vibration assembly includes a fixed rod connected to the turbine blade, two collars are slidably mounted on the outer surface of the fixed rod, and an elastic element is sleeved on the outer surface of the fixed rod between the two collars, with the two ends of the elastic element respectively connected to the opposite ends of the two collars.

[0012] As a further optimization of the present invention, multiple sets of connecting blocks are fixedly installed at both ends of the fixing rod, and the multiple sets of connecting blocks are evenly distributed on the outer surface of the fixing rod. At the same time, a pressing rod is rotatably installed at one end of each connecting block.

[0013] As a further optimization of the present invention, an arc-shaped plate is rotatably mounted on the end of the pressing rod away from the fixed rod, and the outer surface of the arc-shaped plate is slidably connected to the inner wall of the main body.

[0014] As a further optimization of the present invention, a support rod corresponding to the pressing rod is rotatably mounted on the outer surface of the collar, and the end of the support rod away from the collar is rotatably connected to the outer surface of the pressing rod.

[0015] As a further optimization of the present invention, the inner wall of the main body is provided with multiple sets of protrusions, and the protrusions are evenly distributed between two adjacent arc-shaped plates, while the outer surface of the protrusions is arc-shaped.

[0016] Compared with the prior art, the present invention provides a drainage valve for water conservancy projects. When water flows through the first cleaning plate and the second cleaning plate, it comes into contact with the turbine blades, thereby causing the turbine blades to rotate under the impact of the water flow. This causes the second cleaning plate connected to the turbine blades to rotate, thereby crushing and cleaning the impurities in the water, which then flow out under the impact of the water flow.

[0017] The collar supports the pressing rod via a support rod, ensuring that the pressing rod always supports the arc-shaped plate, keeping the arc-shaped plate against the inner wall of the main body. When the arc-shaped plate contacts the protrusion, it squeezes the elastic element. The moment the arc-shaped plate leaves the protrusion, the elastic element pushes the arc-shaped plate against the inner wall of the main body. During this process, the collision between the arc-shaped plate and the main body generates vibration, thereby removing dust adhering to the inside of the main body and allowing it to flow out of the drain valve with the water flow.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example:

[0030] Please see Figure 1 - Figure 6 A drainage valve for water conservancy projects includes a main body 1, the front end of the main body 1 is frustum-shaped, and a cleaning component 2 is provided in the inner cavity of the main body 1 to treat the residue in the drainage valve.

[0031] In this scheme, the main body 1 is located in the inner cavity of the drain valve and is connected to the outside. At the same time, since the front end of the main body 1 is shaped like a frustum, the water flow is centrally discharged.

[0032] Furthermore, the cleaning component 2 includes a pressing block 21, the outer surface of which is slidably connected to the inner wall of the main body 1. A ring 22 is fixedly installed at the lower end of the pressing block 21. Multiple sets of sliding grooves 221 are opened on the outer surface of the ring 22. A limiting block 25 is slidably installed on the inner wall of the sliding groove 221. A cylinder 24 is installed at one end of the limiting block 25. A first cleaning plate 26 is fixedly installed at the lower end of the cylinder 24. A telescopic member 23 is provided in the inner cavity of the ring 22. One end of the telescopic member 23 passes through and extends to the outside of the first cleaning plate 26. A second cleaning plate 27 is fixedly installed on the outer surface of the lower end of the telescopic member 23. A turbine blade 28 is fixedly installed at the lower end of the telescopic member 23.

[0033] In this embodiment, the telescopic member 23 is a device with power output, such as an electric telescopic rod. The telescopic member 23 drives the pressing block 21 to move by telescopic extension and retraction, and then slides on the limiting block 25 through the sliding groove 221 on the ring 22. This causes the cylinder 24 and the first cleaning plate 26 to rotate while the pressing block 21 moves downward. The outer surfaces of the first cleaning plate 26 and the second cleaning plate 27 are both provided with multiple sets of arc-shaped grooves to provide channels for water flow.

[0034] When the water flows through the first cleaning plate 26 and the second cleaning plate 27, it comes into contact with the turbine blades 28, causing the turbine blades 28 to rotate under the impact of the water flow. This causes the second cleaning plate 27, which is connected to the turbine blades 28, to rotate, thereby crushing and cleaning the impurities in the water, which then flow out under the impact of the water flow.

[0035] Furthermore, the upper end of the telescopic member 23 is rotatably connected to the lower end of the pressing block 21, while the cross-section of the ring 22 is smaller than the cross-section of the cylinder 24, and the inner wall of the cylinder 24 is slidably connected to the outer surface of the ring 22.

[0036] Specifically, a limiting block is provided on the outer surface of the pressing block 21 to limit the movement trajectory of the pressing block 21. When the pressing block 21 is subjected to force and moves downward, the ring 22 fits against the inner wall of the cylinder 24, so that a gap is created between the pressing block 21 and the main body 1. External water flows into the other end through the gap. After the drain valve has finished working, the pressing block 21 is restored to the initial position by the telescopic member 23.

[0037] Furthermore, a positioning block 241 is rotatably mounted on the outer surface of the telescopic member 23, and the lower end of the positioning block 241 is connected to the upper end of the first cleaning plate 26.

[0038] Specifically, the positioning block 241 is used to limit the telescopic member 23 so that the telescopic member 23 remains stable during use, and at the same time supports the rotating first cleaning plate 26 so that the first cleaning plate 26 will not tilt when rotating.

[0039] Furthermore, the vibration assembly 3 is mounted at the lower end of the turbine blade 28, and the turbine blade 28 drives the entire vibration assembly 3 to rotate.

[0040] The vibration assembly 3 includes a fixed rod 31 connected to the turbine blade 28. Two collars 32 are slidably mounted on the outer surface of the fixed rod 31. An elastic element 38 is sleeved on the outer surface of the fixed rod 31 between the two collars 32. The two ends of the elastic element 38 are respectively connected to the opposite ends of the two collars 32.

[0041] In this design, the elastic element 38 is a spring or other elastic component. When the turbine blade 28 drives the fixed rod 31 to rotate, the arc plate 36 on the fixed rod 31 contacts the protrusion inside the main body 1 and pushes the arc plate 36 to move towards the fixed rod 31, thereby pushing the collar 32 to move towards the middle position of the fixed rod 31 and squeezing the elastic element 38. When the arc plate 36 leaves the protrusion, the force of the elastic element 38 restores the two collars 32 to their initial positions.

[0042] Furthermore, multiple sets of connecting blocks 35 are fixedly installed at both ends of the fixing rod 31. The multiple sets of connecting blocks 35 are evenly distributed on the outer surface of the fixing rod 31, and a pressing rod 34 is rotatably installed at one end of the connecting block 35. An arc-shaped plate 36 is rotatably installed at the end of the pressing rod 34 away from the fixing rod 31, and the outer surface of the arc-shaped plate 36 is slidably connected to the inner wall of the main body 1. A support rod 33 corresponding to the pressing rod 34 is rotatably installed on the outer surface of the collar 32, and the end of the support rod 33 away from the collar 32 is rotatably connected to the outer surface of the pressing rod 34. Multiple sets of protrusions 37 are provided on the inner wall of the main body 1, and the locking protrusions 37 are evenly distributed between two adjacent arc-shaped plates 36, and the outer surface of the protrusions 37 is arc-shaped.

[0043] Specifically, the collar 32 supports the pressing rod 34 via the support rod 33, ensuring that the pressing rod 34 always supports the arc plate 36, keeping the arc plate 36 against the inner wall of the main body 1. When the arc plate 36 contacts the protrusion 37, it compresses the elastic element 38. The moment the arc plate 36 leaves the protrusion 37, the elastic element 38 pushes the arc plate 36 against the inner wall of the main body 1. During this process, the collision between the arc plate 36 and the main body 1 generates vibration, and this operation is repeated to remove dust adhering to the inside of the main body 1, which then flows out of the drain valve with the water flow.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
