Abstract
Description
Technical Field
[0001] This invention relates to the field of river management technology, and in particular to an interception barrier for river management. Background Technology
[0002] The deployment of oil containment barriers is a core component of water quality emergency response and remediation. Emergency response work requires a rapid response to complete the deployment of oil containment barriers in a short period of time, intercepting oil spills and preventing the spread of pollutants.
[0003] Currently, oil containment barriers are typically deployed in a U-shape, with both ends positioned opposite each other on riverbanks, in the river, or along the banks of a channel. The capture net in the middle of the barrier is shaped U-shaped by the impact of the water flow. During operation, the capture net in the middle of the barrier becomes clogged by floating debris when facing the water flow, reducing the flow of water through the net. This causes the water level on the net's upstream side to rise, eventually overflowing the net and resulting in oil spill escape and failure to contain the spill. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing oil containment barriers that are prone to clogging, and to propose an interception barrier for river management.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design an interception barrier for river management, comprising a main shaft, two fixed blocks, and multiple parallel baffles, wherein:
[0007] The two ends of the main shaft are rotatably mounted on two fixed blocks, and multiple baffles are located between the two fixed blocks. The main shaft passes through the baffles and rotates with them. Four second rollers are rotatably mounted on one side of the baffles. One of the second rollers is fixed to the main shaft. A ring-shaped second capture net for capturing floating oil on the water surface is installed on the second roller.
[0008] Preferably, the baffle has a gear groove inside, and a first driving gear, a transmission gear and a second driving gear are rotatably installed in the gear groove. The first driving gear is fixed to the main shaft, and the transmission gear is located between the first driving gear and the second driving gear to transmit power.
[0009] Preferably, a square rotating rod is rotatably mounted on the other side of the baffle. The rotating rod is fixed to the end face of the second drive gear. A catching plate for catching large pieces of garbage is configured on the rotating rod. A square slot is opened through the catching plate, and the rotating rod is inserted into the slot.
[0010] Preferably, an arc-shaped limiting plate is fixed to the side wall of the baffle to restrict the movement trajectory of the fishing plate.
[0011] Preferably, a wedge-shaped guide plate is fixed to the top of the limiting plate, and the guide plate abuts against the surface of the fishing plate when the fishing plate is rotated to a vertical position.
[0012] Preferably, the baffle has a through-hole for mounting groove, a wedge-shaped stop block is slidably fitted in the mounting groove, and a reset spring is provided in the mounting groove to apply elastic force to the stop block.
[0013] Preferably, two first rollers are rotatably mounted on the outer wall of the baffle, one of which is fixed to the main shaft, and a second capture net is installed on both first rollers.
[0014] Preferably, the bottom of the fixing block is threaded with an extension rod for adjusting the height, and the bottom end of the extension rod is rotatably connected to the base.
[0015] Preferably, a collection box for collecting surface debris is fixedly attached to the outer wall of the fixing block, a grid plate is fixedly attached inside the collection box, and a pipe joint is fixedly installed at the bottom of the side wall of the collection box, the pipe joint communicating with the collection box below the grid plate.
[0016] The present invention proposes an interception barrier for river management, which has the following advantages: The interception barrier provided in this application mainly intercepts and catches floating oil and garbage in the river through a first capture net and a second capture net. By rotating the first and second capture nets, the river water flow backflows from the inside to prevent the nets from clogging. The rotation and vertical sliding of the catching plate scoops up large pieces of floating garbage that are blocked in front of the capture nets, thereby preventing large pieces of floating garbage from accumulating in front of the nets and affecting the oil catching work.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0034] Reference Figures 1-4 A barrier for river management includes a main shaft 2, two fixed blocks 1, and multiple parallel baffles 3. The bottom of the fixed blocks 1 is threaded with an extension rod 24 for height adjustment. The bottom end of the extension rod 24 is rotatably connected to a base 25. A collection box 20 for collecting surface debris is fixed to the outer wall of the fixed blocks 1. A grid plate 21 is fixed inside the collection box 20. A pipe joint 23 is fixed to the bottom of the side wall of the collection box 20. The pipe joint 23 communicates with the collection box 20 below the grid plate 21. The two ends of the main shaft 2 are rotatably mounted on the two fixed blocks 1. Multiple baffles 3 are located between the two fixed blocks 1. The main shaft 2 passes through the baffles 3 and rotatably engages with them. Four second rollers 5 are rotatably mounted on one side of the baffles 3. One of the second rollers 5 is fixed to the shaft of the main shaft 2. A ring-shaped second capture net 18 for capturing floating oil on the water surface is installed on the second roller 5.
[0035] During installation, the base 25 is sunk to the bottom of the river. The height of the fixing block 1 is adjusted by replacing the extension rods 24 of different lengths. The fixing block 1 is equipped with a water level line 22. After installation, the water level line 22 is flush with the river surface.
[0036] During the interception operation, the diesel engine drives the main shaft 2 to rotate, which in turn drives the second roller 5 to rotate. During the rotation of the second roller 5, the second ring-shaped second capture net 18 will rotate. The second capture net 18 will capture the oil floating on the river surface, causing the oil to adhere to the second capture net 18. The edge of the collection box 20 abuts against the second capture net 18. The oil will move to the collection box 20 as the second capture net 18 rotates. The edge of the collection box 20 will scrape off the oil on the second capture net 18. The scraped oil will pass through the grid plate 21 under the action of gravity and fall into the bottom of the collection box 20. Large impurities attached to the second capture net 18 will remain on the grid plate 21 to separate the oil from solid waste. The oil collected at the bottom of the collection box 20 can be discharged centrally through the pipe joint 23.
[0037] When the second capture net 18 moves to the side where the collection box 20 is located, the water-facing side will change from the original outer side to the inner side of the ring-shaped second capture net 18, so that the flow of river water in the river channel can backwash the second capture net 18 and prevent the mesh of the second capture net 18 from becoming clogged.
[0038] like Figure 10 and Figure 13 As shown, a gear groove 13 is provided inside the baffle 3. A first drive gear 6, a transmission gear 7 and a second drive gear 8 are rotatably installed in the gear groove 13. The first drive gear 6 is fixed to the shaft of the main shaft 2, and the transmission gear 7 is located between the first drive gear 6 and the second drive gear 8 to transmit power.
[0039] During the rotation of the main shaft 2, the first drive gear 6 will be driven to rotate. The rotation of the first drive gear 6 will drive the second drive gear 8 to rotate through the transmission gear 7. The rotation direction of the first drive gear 6 and the second drive gear 8 are the same.
[0040] like Figures 5-9 As shown, a square rotating rod 9 is rotatably installed on the other side of the baffle 3. The rotating rod 9 is fixed on the end face of the second drive gear 8. A catching plate 15 for catching large pieces of garbage is arranged on the rotating rod 9. A square slot 16 is opened through the catching plate 15. The rotating rod 9 is inserted into the slot 16. A wedge-shaped cut 12 is provided on the baffle 3 so that floating garbage can be collected here.
[0041] During the rotation of the second drive gear 8, the rotating rod 9 will rotate synchronously. During the rotation of the rotating rod 9, the fishing plate 15 will rotate synchronously. During the rotation of the fishing plate 15, large pieces of floating garbage will be retrieved and collected in the collection box 20.
[0042] by Figure 5For example, when the fishing plate 15 rotates 180 degrees counterclockwise from the state shown in the figure and becomes vertical, it will slide down the rotating rod 9 under the action of gravity, thus restoring the fishing plate 15 to its initial state. This cycle is repeated to continuously salvage large pieces of floating garbage on the river surface.
[0043] like Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, an arc-shaped limiting plate 10 is fixed to the side wall of the baffle 3 to restrict the movement trajectory of the fishing plate 15. A wedge-shaped guide plate 14 is fixed to the top of the limiting plate 10. The guide plate 14 is made of rubber material and has a certain deformation capability. When the fishing plate 15 rotates to the vertical position, the guide plate 14 abuts against the surface of the fishing plate 15.
[0044] During the process of rotating the fishing plate 15 180 degrees from its initial state, the end of the fishing plate 15 will abut against the arc-shaped limiting plate 10, thereby limiting the fishing plate 15 to prevent it from sliding down during the rotation, so that the fishing plate 15 can only move down when it is in a vertical state.
[0045] like Figures 7-13 As shown, a mounting groove 11 is provided through the baffle 3, and a wedge-shaped stop 19 is slidably fitted in the mounting groove 11. A reset spring 26 is provided in the mounting groove 11 to apply elastic force to the stop 19.
[0046] During the rotation of the fishing plate 15, the stop block 19 will be pushed open to make enough space to accommodate the rotation of the fishing plate 15. When the fishing plate 15 is in a vertical state, the stop blocks 19 on both sides will close the space where the fishing plate 15 is located under the elastic force of the return spring 26, thereby preventing large pieces of floating garbage on the water surface from entering during the operation of the fishing plate 15.
[0047] like Figures 7-11 As shown, two first rollers 4 are rotatably mounted on the outer wall of the baffle 3. One of the first rollers 4 is fixed to the shaft of the main shaft 2, and a second capture net 17 is installed on both first rollers 4.
[0048] During the rotation of the main shaft 2, the first rotating roller 4 will also be driven to rotate. The rotation of the first rotating roller 4 will drive the first annular capture net 17 to operate. During the operation of the first capture net 17, floating oil sludge entering the space where the fishing plate 15 is located can be captured, thereby preventing the oil sludge floating on the river surface from escaping from here.
[0049] Working principle:
[0050] During installation, the base 25 is sunk to the bottom of the river. The height of the fixing block 1 is adjusted by replacing the extension rods 24 of different lengths. The fixing block 1 is equipped with a water level line 22. After installation, the water level line 22 is flush with the river surface.
[0051] During the interception operation, the diesel engine drives the main shaft 2 to rotate, which in turn drives the second roller 5 to rotate. During the rotation of the second roller 5, the second ring-shaped second capture net 18 will rotate. The second capture net 18 will capture the oil floating on the river surface, causing the oil to adhere to the second capture net 18. The edge of the collection box 20 abuts against the second capture net 18. The oil will move to the collection box 20 as the second capture net 18 rotates. The edge of the collection box 20 will scrape off the oil on the second capture net 18. The scraped oil will pass through the grid plate 21 under the action of gravity and fall into the bottom of the collection box 20. Large impurities attached to the second capture net 18 will remain on the grid plate 21 to separate the oil from solid waste. The oil collected at the bottom of the collection box 20 can be discharged centrally through the pipe joint 23.
[0052] When the second capture net 18 moves to the side where the collection box 20 is located, the water-facing side will change from the original outer side to the inner side of the ring-shaped second capture net 18, so that the flow of river water in the river channel can backwash the second capture net 18 and prevent the mesh of the second capture net 18 from becoming clogged.
[0053] During the rotation of the main shaft 2, the first drive gear 6 will be driven to rotate. The rotation of the first drive gear 6 will drive the second drive gear 8 to rotate through the transmission gear 7. The rotation direction of the first drive gear 6 and the second drive gear 8 are the same.
[0054] During the rotation of the second drive gear 8, the rotating rod 9 will rotate synchronously. During the rotation of the rotating rod 9, the fishing plate 15 will rotate synchronously. During the rotation of the fishing plate 15, large pieces of floating garbage will be retrieved and collected in the collection box 20.
[0055] by Figure 5 For example, when the fishing plate 15 rotates 180 degrees counterclockwise from the state shown in the figure and becomes vertical, it will slide down the rotating rod 9 under the action of gravity, thus restoring the fishing plate 15 to its initial state. This cycle is repeated to continuously salvage large pieces of floating garbage on the river surface.
[0056] During the process of rotating the fishing plate 15 180 degrees from its initial state, the end of the fishing plate 15 will abut against the arc-shaped limiting plate 10, thereby limiting the fishing plate 15 to prevent it from sliding down during the rotation, so that the fishing plate 15 can only move down when it is in a vertical state.
[0057] During the rotation of the fishing plate 15, the stop block 19 will be pushed open to make enough space to accommodate the rotation of the fishing plate 15. When the fishing plate 15 is in a vertical state, the stop blocks 19 on both sides will close the space where the fishing plate 15 is located under the elastic force of the return spring 26, thereby preventing large pieces of floating garbage on the water surface from entering during the operation of the fishing plate 15.
[0058] During the rotation of the main shaft 2, the first rotating roller 4 will also be driven to rotate. The rotation of the first rotating roller 4 will drive the first annular capture net 17 to operate. During the operation of the first capture net 17, floating oil sludge entering the space where the fishing plate 15 is located can be captured, thereby preventing the oil sludge floating on the river surface from escaping from here.
[0059] Compared to existing technologies, this application provides an interception barrier for river management, which mainly uses a first capture net 17 and a second capture net 18 to intercept and catch floating oil and garbage in the river. The rotation of the first capture net 17 and the second capture net 18 causes the river water to backwash them from the inside, preventing the mesh from getting clogged. The rotation and vertical sliding of the catching plate 15 are used to scoop up large pieces of floating garbage that are blocked in front of the capture net, thereby preventing large pieces of floating garbage from accumulating in front of the net and affecting the oil catching work.
[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
