Description

Technical Field

[0001] This invention belongs to the field of sluice gate garbage interception technology, specifically a garbage interception device for water conservancy projects using sluice gates. Background Technology

[0002] Garbage interception at sluice gates in water conservancy projects refers to engineering techniques used to intercept, collect, and treat floating and suspended garbage and debris in the water flow by setting up specialized facilities at the sluice gates or utilizing the sluice gates themselves. Its core purpose is to prevent garbage from entering downstream waters or critical facilities, ensuring the safe operation of water conservancy projects, improving water quality, and reducing environmental pollution.

[0003] Currently, the interception nets installed upstream of sluice gates can effectively prevent upstream garbage from entering downstream waters. However, under the continuous action of water flow, garbage gradually accumulates at the interception nets. Long-term accumulation of garbage may increase the load on the interception nets and affect the interception effect. Conventional cleaning methods require manual operation on the bank using retrieval tools. However, when the river channel is wide, the retrieval tools need to be lengthened to reach the garbage accumulation area. The increase in tool length leads to a decrease in rigidity, which not only significantly reduces the efficiency of garbage retrieval but also increases the safety risks of operators due to factors such as excessive operating distance and unstable force. This problem is more prominent under conditions of high flow velocity or large water level fluctuations. Therefore, a garbage interception device using sluice gates in water conservancy projects is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a garbage interception device for water conservancy projects using sluice gates. This device solves the problems that while existing upstream interception nets can effectively intercept garbage, long-term accumulation will increase the load on the net body. Furthermore, manual retrieval in wide rivers is inefficient and lacks rigidity due to excessively long tools, and poses safety hazards when the flow rate is fast or the water level fluctuates.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste interception device for water conservancy projects using a sluice gate, comprising a river mounting frame installed in a river channel, wherein a sluice gate body for river interception is mounted on the river mounting frame, and further comprising: The first interception component is mounted on the river mounting frame and is located in the upstream area of ​​the sluice gate body, and is used to intercept river garbage. A collection component, which is disposed at both ends of the river channel mounting frame, is used to collect the garbage intercepted by the first interception component; The first interception component includes a beam plate fixed on the river channel mounting frame, the beam plate having a groove, and a docking sliding member slidably disposed in the groove; The top of the river channel mounting frame is provided with a threaded rod, the threads at both ends of the threaded rod are in opposite directions, the mating sliding member is threadedly sleeved on both ends of the threaded rod, and a drive motor for driving the threaded rod is installed on the top of the river channel mounting frame. A mandrel is movably mounted on the docking sliding member, and a cleaning plate is mounted on the outside of the mandrel via a support frame; The river channel mounting frame is equipped with an interception net plate located upstream of the sluice gate body for intercepting garbage, and the cleaning plate is located upstream of the interception net plate; Initially, the two cleaning plates are located in the middle of the interception mesh. The drive motor drives the threaded rod to rotate, causing the two cleaning plates to push the garbage accumulated upstream of the interception mesh towards both ends.

[0006] Preferably, the collection assembly includes garbage collection troughs disposed on both sides of the river mounting frame for collecting garbage intercepted by the interception mesh, and drainage troughs are provided at equal intervals on the sides of the collection troughs; A collection port is provided on one side of the collection tank.

[0007] Preferably, the river mounting frame is provided with a valve plate for sealing the collection port, the top of the river mounting frame is provided with a guide wheel through a beam frame, and both ends of the threaded rod are fixed with winding wheels. The winding wheels are connected to the top of the valve plate through a connecting rope passing through the guide wheel.

[0008] Preferably, the cleaning board is a solid board; The collection port is kept horizontal with the side of the interception mesh plate. When the two cleaning plates are initially located in the middle of the interception mesh plate, the valve plate blocks the collection port.

[0009] Preferably, the river channel mounting frame is provided with a guiding dredging component, which includes a guide frame fixed to the inner wall of the river channel mounting frame. The guide frame is located in the upstream area of ​​the intercepting net plate, and the distance between the guide frame and the bottom of the river channel mounting frame gradually decreases from the water-facing end.

[0010] Preferably, the bottom of the guide frame is fixedly mounted with a slide rail, and the bottom of the support frame slides on the slide rail via a mating member.

[0011] Preferably, a second interception assembly is provided between the beam plate and the guide frame. The second interception assembly includes a fixing rod fixed between the beam plate and the guide frame, and an interception net is provided outside the fixing rod. The two ends of the interception net are respectively wrapped around the mandrel.

[0012] Preferably, a transmission gear plate is fixedly mounted on the top of the beam plate, and a transmission gear that meshes with the transmission gear plate is fixedly mounted on the upper end of the spindle. As the two docking sliding members slide along the slide groove, driving the spindle, support frame and cleaning plate to slide respectively, the transmission gear and spindle rotate along the transmission gear plate to gradually unfold the interception net.

[0013] Preferably, the first interception component further includes a U-shaped baffle installed at the end of the cleaning plate, the U-shaped baffle having a through groove; A cleaning component is fixed to the top of the U-shaped baffle via a connector, and the cleaning component is located on the back side of the intercepting mesh.

[0014] Preferably, the cleaning component has a gathering groove, and the cleaning component has backflush nozzles that communicate with the gathering groove at equal intervals; The other end of the backjet nozzle remains vertical to the middle of the U-shaped baffle cross section.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a drive motor to rotate a threaded rod. Since the threads at both ends of the threaded rod are in opposite directions, the sliding parts drive the support frame and cleaning plate to move along the slide groove to both ends, pushing the garbage accumulated in the upstream area of ​​the intercepting net to both ends and collecting it in the collection assembly. By repeatedly rotating the threaded rod forward and backward with the drive motor, the cleaning plate can clean the garbage intercepted by the intercepting net. This invention can adapt to rivers of different widths, thus avoiding excessive garbage interception by the intercepting net, which would increase the load on the intercepting net. Regularly cleaning the garbage collected in the collection assembly improves the efficiency of river garbage retrieval, reduces operating distance, and ensures the safety of operators.

[0016] This invention uses a drive motor to drive a threaded rod, causing two mating sliding parts to move synchronously towards both ends along a sliding groove. This movement also drives the mandrel, support frame, transmission gear, and cleaning plate towards both ends. The cleaning plate pushes the intercepting net plate to intercept the garbage, while the transmission gear, moving along the transmission tooth plate, drives the mandrel to rotate, loosening the intercepting net. The intercepting net gradually unfolds following the movement of the cleaning plate, protecting the gap between the two cleaning plates and preventing river garbage from entering between them under the action of water flow. Simultaneously, as the two cleaning plates move relative to each other, the transmission gear rotates in the opposite direction along the transmission tooth plate, causing the mandrel to reel in the end of the intercepting net. During the reeling process, the garbage intercepted by the net gradually enters between the cleaning plate and the river mounting frame, causing the garbage to become stuck between the two cleaning plates and unable to be cleaned.

[0017] This invention utilizes the impact of river water flow on the inner wall of the collecting groove, and the backwashing impact on the back surface of the intercepting mesh plate guided by backwash nozzles. During this process, the river water flow is blocked by U-shaped baffles, creating a low-pressure area on the back surface of the U-shaped baffles. The river water flow can then normally impact the back surface of the intercepting mesh plate through the backwash nozzles, achieving backwashing of the intercepting mesh plate and improving its permeability. Meanwhile, the cleaning component moves synchronously with the cleaning plate to achieve comprehensive backwashing of the intercepting mesh plate. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 9 As shown, the present invention provides a water conservancy project sluice gate garbage interception device, including a river channel mounting frame 1 installed in a river channel, a sluice gate body 4 for river interception on the river channel mounting frame 1, and further including: The first interception component 2 is installed on the river mounting frame 1 and is located in the upstream area of ​​the sluice gate body 4. It is used to intercept river garbage. Collection component 5 is set at both ends of the river mounting frame 1 and is used to collect the garbage intercepted by the first interception component 2; The first interception component 2 includes a beam plate 26 fixedly mounted on the river mounting frame 1. A groove 27 is provided on the beam plate 26, and a docking sliding member 25 is slidably disposed in the groove 27. The top of the river channel mounting frame 1 is provided with a threaded rod 29, the threads at both ends of the threaded rod 29 are opposite in direction, the sliding part 25 is threadedly sleeved on both ends of the threaded rod 29, and the top of the river channel mounting frame 1 is provided with a drive motor for driving the threaded rod 29. A spindle 20 is movably mounted on the docking sliding member 25, and a cleaning plate 21 is mounted on the outside of the spindle 20 via a support frame 23; The river channel mounting frame 1 is equipped with an interception net plate 22 located upstream of the sluice gate body 4 for intercepting garbage, and the cleaning plate 21 is located upstream of the interception net plate 22; Initially, the two cleaning plates 21 are located in the middle of the interception net plate 22. The drive motor drives the threaded rod 29 to rotate, causing the two cleaning plates 21 to push the garbage accumulated upstream of the interception net plate 22 to move to both ends.

[0022] The sluice gate body 4 controls the flow rate of the river water. During the water flow, the intercepting net plate 22 intercepts the garbage in the river, causing the garbage to accumulate in the upstream area of ​​the intercepting net plate 22. As the garbage gradually increases, it affects the flow rate of the river water. Initially, the two cleaning plates 21 are located in the middle of the upstream area of ​​the intercepting net plate 22. The drive motor drives the threaded rod 29 to rotate. Since the threads at both ends of the threaded rod 29 are opposite, the connecting sliding part 25 drives the support frame 23 and the cleaning plate 21 to move along the slide 27 to both ends, pushing the garbage accumulated in the upstream area of ​​the intercepting net plate 22 to both ends and collecting it in the collection component 5. In this way, the drive motor drives the threaded rod 29 to rotate repeatedly in both directions, so that the garbage intercepted by the intercepting net plate 22 can be cleaned by the cleaning plate 21. It can adapt to river channels of different widths, thereby avoiding the intercepting net plate 22 from intercepting too much garbage, which would increase the load on the intercepting net. The garbage collected in the collection component 5 is cleaned regularly, improving the efficiency of river garbage retrieval, reducing the operating distance and ensuring the safety of the operators.

[0023] like Figure 3 , Figure 4 and Figure 8 As shown, the collection component 5 includes collection troughs 51 set on both sides of the river mounting frame 1 for collecting garbage intercepted by the interception net plate 22. Drainage troughs 54 are equidistantly provided on the sides of the collection troughs 51. A collection port 52 is provided on one side of the collection tank 51; The river mounting frame 1 is equipped with a valve plate 53 for sealing the collection port 52. The top of the river mounting frame 1 is equipped with a guide wheel 58 through the beam frame 55. Both ends of the threaded rod 29 are fixed with winding wheels 57. The winding wheels 57 are connected to the top of the valve plate 53 through the guide wheel 58 via the connecting rope 56. Cleaning board 21 is a solid board; The collection port 52 is kept horizontal with the side of the interception plate 22. When the two cleaning plates 21 are initially located in the middle of the interception plate 22, the valve plate 53 blocks the collection port 52.

[0024] The drive motor drives the threaded rod 29 to rotate, causing the two cleaning plates 21 to synchronously push the river garbage outward. During the rotation of the threaded rod 29, the winding wheel 57 winds up the connecting rope 56 and pulls the valve plate 53 upward, gradually bringing the collection port 52 into a fully open state. When the cleaning plate 21 moves to the end of the intercepting net plate 22, the collection port 52 is fully open. Since the cleaning plate 21 is made of solid plate, the river water flow increases its speed between the cleaning plate 21 and the river mounting frame 1. Under the action of the water flow, the garbage between the cleaning plate 21 and the river mounting frame 1 is pushed through the collection port 52 and into the collection tank 51. The water flows back into the river through the drainage ditch 54, thus realizing the collection of river garbage. Then, the drive motor drives the threaded rod 29 to rotate in the opposite direction, and the winding wheel 57 releases the connecting rope 56. The valve plate 53, under its own weight, blocks the collection port 52, preventing the garbage collected in the collection tank 51 from flowing backward.

[0025] like Figure 8 and Figure 9 As shown, a guide dredging component 6 is provided on the river channel mounting frame 1. The guide dredging component 6 includes a guide frame 61 fixed to the inner wall of the river channel mounting frame 1. The guide frame 61 is located in the upstream area of ​​the interception net plate 22. The distance between the guide frame 61 and the bottom of the river channel mounting frame 1 gradually decreases from the water-facing end.

[0026] When the river water flows through the gap between the guide frame 61 and the river mounting frame 1, the distance between the guide frame 61 and the river mounting frame 1 gradually decreases from the water-facing end. The guide frame 61 guides the river water to increase its flow velocity, and the river water impacts the bottom of the river mounting frame 1, preventing silt from settling and raising the riverbed, thus avoiding affecting the water flow velocity.

[0027] like Figure 9 As shown, the bottom of the guide frame 61 is fixedly mounted with a slide rail 62, and the bottom of the support frame 23 slides on the slide rail 62 through the docking part 63.

[0028] The drive motor drives the threaded rod 29 to rotate, causing the two mating sliding parts 25, the support frame 23 and the cleaning plate 21 to move along the slide groove 27 and the slide rail 62. The slide groove 27 and the slide rail 62 ensure the stability of the cleaning plate 21 in pushing the garbage and prevent the cleaning plate 21 from tilting or getting stuck.

[0029] like Figure 6 and Figure 7 As shown, a second interception assembly 3 is provided between the beam plate 26 and the guide frame 61. The second interception assembly 3 includes a fixing rod 31 fixed between the beam plate 26 and the guide frame 61, and an interception net 32 ​​is provided on the outside of the fixing rod 31. The two ends of the interceptor net 32 ​​are respectively wrapped around the spindle 20; A transmission gear plate 28 is fixedly mounted on the top of the beam plate 26, and a transmission gear 24 that meshes with the transmission gear plate 28 is fixedly mounted on the upper end of the spindle 20. As the two docking sliding parts 25 slide along the slide groove 27, they drive the spindle 20, the support frame 23 and the cleaning plate 21 to slide respectively. Meanwhile, the transmission gear 24 and the spindle 20 rotate along the transmission gear plate 28 to gradually unfold the interception net 32.

[0030] The drive motor drives the threaded rod 29, causing the two mating sliding parts 25 to move synchronously to both ends along the slide groove 27. This drives the spindle 20, support frame 23, transmission gear 24, and cleaning plate 21 to move to both ends. The cleaning plate 21 pushes the intercepting net plate 22 to intercept the garbage. As the transmission gear 24 moves along the transmission tooth plate 28, it drives the spindle 20 to rotate, loosening the intercepting net 32. The intercepting net 32 ​​gradually unfolds with the movement of the cleaning plate 21, protecting the gap between the two cleaning plates 21 and preventing river garbage from entering between the two cleaning plates 21 under the action of water flow. At the same time, as the two cleaning plates 21 move relative to each other, the transmission gear 24 rotates in the opposite direction along the transmission tooth plate 28, and the spindle 20 rolls up the end of the intercepting net 32. During the rolling process, the garbage intercepted by the intercepting net 32 ​​gradually enters between the cleaning plate 21 and the river mounting frame 1, causing the garbage to get stuck between the two cleaning plates 21 and cannot be cleaned. The garbage intercepted by the intercepting net plate 22 can then be cleaned by the cleaning plate 21.

[0031] like Figures 4-6 As shown, the first interception component 2 also includes a U-shaped baffle 211 installed at the end of the cleaning plate 21, and the U-shaped baffle 211 has a through groove 212. A cleaning component 213 is fixedly mounted on the top of the U-shaped baffle 211 via a connector 216. The cleaning component 213 is located on the back side of the intercepting net plate 22. The cleaning component 213 is provided with a gathering groove 215, and the cleaning component 213 is provided with back jet nozzles 214 that communicate with the gathering groove 215 at equal intervals. The other end of the backjet nozzle 214 remains vertical to the middle of the cross section of the U-shaped baffle 211.

[0032] During the flow of river water, it impacts the inner wall of the collecting groove 215 and is guided by the backwash nozzle 214 to impact the backwater surface of the intercepting net plate 22. During this process, the river water is blocked by the U-shaped baffle 211, creating a low-pressure area on the backwater surface of the U-shaped baffle 211. The river water can then impact the backwater surface of the intercepting net plate 22 normally through the backwash nozzle 214, achieving backwashing of the intercepting net plate 22 and improving its permeability. Meanwhile, the cleaning component 213 moves synchronously with the cleaning plate 21 to achieve comprehensive backwashing of the intercepting net plate 22. When the two cleaning plates 21 move synchronously to both ends, the intercepting net 32 ​​unfolds to prevent river debris from entering between the two cleaning plates 21 and being intercepted by the intercepting net plate 22, thus affecting the permeability of the intercepting net plate 22. This ensures that the river water can normally impact the inner wall of the collecting groove 215, ensuring the backwashing effect of the intercepting net plate 22.

[0033] Working principle and usage process of this invention: The flow rate of the river water is controlled by the main body 4 of the sluice gate. During the water flow, the garbage in the river is intercepted by the interception net plate 22, causing the garbage to accumulate in the upstream area of ​​the interception net plate 22. As the garbage gradually increases, it affects the flow rate of the river water. Initially, the two cleaning plates 21 are located in the middle of the upstream area of ​​the interception net plate 22. The drive motor drives the threaded rod 29 to rotate. Since the threads at both ends of the threaded rod 29 are opposite, the connecting sliding part 25 drives the support frame 23 and the cleaning plate 21 to move along the slide 27 and the slide rail 62 to both ends, pushing the garbage accumulated in the upstream area of ​​the interception net plate 22 to both ends and collecting it in the collection component 5. In this way, the drive motor drives the threaded rod 29 to rotate repeatedly in both directions, so that the garbage intercepted by the interception net plate 22 can be cleaned by the cleaning plate 21. Two cleaning plates 21 simultaneously push the river garbage outwards, while the threaded rod 29 rotates and the winding wheel 57 winds up the connecting rope 56 and pulls the valve plate 53 upwards, so that the collection port 52 gradually opens completely. When the cleaning plate 21 moves to the end of the interception net plate 22, the collection port 52 is fully open. Since the cleaning plate 21 is made of solid plate, the river water increases its flow speed between the cleaning plate 21 and the river mounting frame 1. Under the action of the water flow, the garbage between the cleaning plate 21 and the river mounting frame 1 is pushed through the collection port 52 and into the collection tank 51. The water flows back into the river through the drainage ditch 54, thus realizing the collection of river garbage. Then, the drive motor drives the threaded rod 29 to rotate in the opposite direction. The winding wheel 57 loosens the connecting rope 56 and the valve plate 53 seals the collection port 52 under its own weight, preventing the garbage collected in the collection tank 51 from flowing back. The cleaning plate 21 pushes the intercepting net plate 22 to intercept the garbage, while the transmission gear 24 drives the spindle 20 to rotate as it moves along the transmission tooth plate 28, which loosens the intercepting net 32. The intercepting net 32 ​​gradually unfolds as it moves with the cleaning plate 21. The intercepting net 32 ​​protects the gap between the two cleaning plates 21, preventing river garbage from entering between the two cleaning plates 21 under the action of water flow. At the same time, as the two cleaning plates 21 move relative to each other, the transmission gear 24 rotates in the opposite direction along the transmission tooth plate 28 and rolls up the end of the intercepting net 32 ​​through the spindle 20. During the rolling process, the garbage intercepted by the intercepting net 32 ​​gradually enters between the cleaning plate 21 and the river mounting frame 1, causing the garbage to get stuck between the two cleaning plates 21 and cannot be cleaned. During the flow of river water, it impacts the inner wall of the collecting groove 215 and is guided by the backwash nozzle 214 to impact the backwater surface of the intercepting mesh plate 22. During this process, the river water is blocked by the U-shaped baffle 211, which creates a low-pressure area on the backwater surface of the U-shaped baffle 211. The river water can then impact the backwater surface of the intercepting mesh plate 22 normally through the backwash nozzle 214, thereby achieving backwashing of the intercepting mesh plate 22 and improving its permeability.
