Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a pollutant interception structure for water conservancy channels. Background Technology

[0002] Water conservancy channels are artificially excavated, filled, or lined hydraulic structures with free water surfaces, used for water diversion, conveyance, distribution, drainage, and ecological water replenishment. During water conveyance, floating pollutants such as weeds and branches in the water can easily enter the water use area with the water flow, requiring interception structures to be installed in the channels to trap floating debris.

[0003] The current mainstream interception facility is the pontoon, which is made of HDPE rotational molding and filled with polyurethane closed-cell foam. It will not sink after the outer shell is damaged. The pontoons are connected end to end by nylon cables passing through the end holes to form a floating raft, which intercepts floating objects on the water surface and can automatically rise and fall with the water level, adapting to the water level changes in the canal during the flood season and dry season.

[0004] After a period of operation, a large amount of pollutants will accumulate on one side of the pontoon. If not cleaned in time, the pollutants will overturn over the pontoon, causing it to fail to intercept the pollution. Currently, manual cleaning by boat is commonly used: workers ride in small salvage boats along the rafts and use salvage nets to remove the pollutants accumulated on the side of the pontoon. This method has the drawbacks of low work efficiency and poor safety; at the same time, the gliding of the small boat generates water waves, causing floating objects to overturn over the pontoon under the impact of water, further weakening the pollution interception and cleaning effect. Therefore, this invention provides a pollutant interception structure for water conservancy channels to meet the requirements. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a pollutant interception structure for water conservancy channels. By setting up a sewage discharge mechanism, floating pollutants in the channel can be intercepted and guided by a second pontoon to gather at the location of the floating frame, and finally be uniformly collected and retained in the sewage discharge mechanism. This structural design allows various floating pollutants intercepted by the second pontoon to be centrally collected in a designated area, facilitating centralized and batch cleaning of pollutants by workers, significantly improving the efficiency of pollutant cleaning operations, reducing labor costs, and solving the problems of low efficiency, poor safety, and incomplete cleaning in the current process of cleaning pollutants accumulated on the side of the pontoon.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A pollutant interception structure for a water conservancy channel includes two sets of floating frames and several second pontoons connected end-to-end. The second pontoons are assembled into a continuous floating raft by nylon ropes passing through through holes at both ends. Each end of a second pontoon has a protrusion and a recess, which are structurally compatible. Guide cylinders are fixedly connected to both ends of each floating frame, and a column is slidably inserted inside the guide cylinder. The bottom end of the column is fixed to the bottom of the channel. Side mounting plates are fixedly connected to the outer walls of both sets of floating frames, and a first pontoon is fixedly connected to the bottom of the side mounting plates. A sewage discharge gap is reserved between the two sets of floating frames, and a sewage discharge mechanism is installed in the sewage discharge gap. The sewage discharge mechanism is used to collect and treat pollutants accumulated on one side of the second pontoons. The sewage discharge mechanism includes two sets of side baffles rotatably connected to the inner walls of the floating frames. A first collection net, a second collection net, and a third collection net are fixedly connected between the two sets of side baffles from top to bottom. An adjusting rod is fixedly connected to the end of the side baffle away from the second pontoon.

[0007] Optionally, one end of the nylon rope is fixed to the bank of the channel, and the other end is fixed to the outer wall of the guide cylinder. Several second floats and two sets of floating frames enclose a U-shaped outline structure.

[0008] Optionally, the first collecting net and the third collecting net are respectively installed on the top and bottom end faces of the side baffle.

[0009] Optionally, the first collection net, the second collection net, and the third collection net divide the sewage gap between the two sets of side baffles into two independent chambers.

[0010] Optionally, a handwheel is fixedly connected to one end of the adjusting rod, and an adjusting plate is fixedly connected to the outer wall of the end of the adjusting rod near the handwheel.

[0011] Optionally, a rod is provided through the adjustment plate, and an adjustment slot is provided through the floating frame near the adjustment rod. The rod passes through the adjustment plate and the floating frame in sequence and is inserted into the adjustment slot.

[0012] Optionally, a spring is sleeved on the outer side of the insertion rod, one end of the spring is fixed to the outer wall of the adjusting plate, and the other end of the spring is fixed to the insertion rod.

[0013] Optionally, a first rear baffle is fixedly connected to one end of the first collecting net near the adjusting rod, and a second rear baffle is fixedly connected to one end of the third collecting net near the adjusting rod.

[0014] Optionally, a first drain plate and a second drain plate are rotatably connected to the first rear baffle and the second rear baffle, respectively, and the first rear baffle and the first drain plate, as well as the second rear baffle and the second drain plate, are fixed by locking fasteners.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a sewage discharge mechanism, floating pollutants in the channel can be intercepted and guided by the second pontoon to gather at the location of the floating frame, and finally be uniformly collected and retained in the sewage discharge mechanism. This structural design allows various floating pollutants intercepted by the second pontoon to be centrally collected in a designated area, facilitating centralized and batch cleaning of pollutants by staff, greatly improving the efficiency of pollutant cleaning operations and reducing labor costs.

[0016] Furthermore, when cleaning pollutants in the sewage discharge mechanism, staff can adjust the rotating adjustment rod to move the chamber containing the pollutants away from the water surface and tilt it downwards. During the cleaning process, the pollutants accumulated in the chamber will automatically fall outwards under the action of gravity, achieving rapid cleaning of pollutants. The overall operation is convenient, efficient and labor-saving.

[0017] Furthermore, if the amount of pollutants accumulated during equipment operation exceeds the capacity of the chamber between the first and second collection nets, the operator can rotate the adjusting rod to tilt the chamber between the first and second collection nets. Excess pollutants can then be automatically diverted into the chamber between the second and third collection nets for temporary storage, effectively preventing residual accumulation during high-flow-rate pollutant cleaning and ensuring thorough cleaning. Simultaneously, after the pollutants in the chambers of the first and second collection nets have been cleaned, the operator can continue to rotate the adjusting rod to further process the pollutants in the chambers of the second and third collection nets, ensuring the device is free of dirt and residue, maintaining its cleanliness and allowing it to be readily put back into normal interception operations, effectively improving the overall cleaning effect and operational efficiency.

[0027] like Figures 1 to 3As shown, an embodiment of the present invention provides a pollutant interception structure for a water conservancy channel, including two sets of floating frames 1 and several second floats 6 connected end-to-end. The several second floats 6 are assembled into a continuous floating platform by nylon ropes passing through their two end holes. Workers fix the nylon ropes at both ends of the floating platform to both banks of the channel. At this time, the second floats 6 can intercept pollutants floating on the water surface, preventing pollutants from flowing into the water-using section along the water flow direction. Each end of the second float 6 is provided with a protrusion 7 and a recess 8, the protrusion 7 and the recess 8 being structurally compatible. With this structural arrangement, when the several second floats 6 are assembled end-to-end and put into operation, adjacent sets of second floats 6 can form a stable cooperation based on the structural compatibility of the protrusion 7 and the recess 8, effectively preventing the second floats 6 from being submerged in the water. Displacement occurs under the disturbance of surface ripples, ensuring that the pollutant interception effect is not affected. Both ends of the floating frame 1 are fixedly connected to guide cylinders 2. One end of the nylon rope is fixed to the bank of the channel, and the other end is fixed to the outer wall of the guide cylinder 2. Several second floats 6 and the two sets of floating frames 1 form a U-shaped outline structure. Columns 3 are slidably inserted inside the guide cylinders 2. The bottom end of the column 3 is fixed to the bottom of the channel. Side mounting plates 4 are fixedly connected to the outer walls of the two sets of floating frames 1. The bottom of the side mounting plates 4 is fixedly connected to the first floats 5. The four columns 3 are fixedly installed at the bottom of the channel. The four columns 3 are paired in pairs to form two sets of structures. The two sets of columns 3 limit and guide the two sets of floating frames 1, effectively ensuring the overall stability of the two sets of floating frames 1 as they rise and fall with the water level inside the channel. Because the floating frame 1 is equipped with the first floats 5 on the outside, under the buoyancy support of the first floats 5, the floating frame 1 can float synchronously with the second floats 6 on the surface of the channel. Once the entire interception structure is deployed, the U-shaped outline formed by the second pontoon 6 and the floating frame 1 faces the direction of water flow. Floating pollutants in the channel can be guided and intercepted by the second pontoon 6, converging towards the floating frame 1 and ultimately remaining there. This structural design allows various floating pollutants intercepted by the second pontoon 6 to be collected in a designated area, facilitating centralized and batch cleaning by staff, significantly improving the efficiency of pollutant cleanup operations and reducing labor costs.

[0028] As one implementation method in this embodiment, such as Figures 1 to 10As shown, a sewage discharge gap is reserved between the two sets of floating frames 1. A sewage discharge mechanism is installed in the sewage discharge gap. The sewage discharge mechanism is used to collect and treat pollutants accumulated on one side of the second float 6. The sewage discharge mechanism includes two sets of side baffles 9 rotatably connected to the inner wall of the floating frame 1. A first collection net 10, a second collection net 11, and a third collection net 12 are fixedly connected between the two sets of side baffles 9 from top to bottom. The first collection net 10 and the third collection net 12 are respectively installed on the top end face and the bottom end face of the side baffles 9. The first collection net 10, the second collection net 11, and the third collection net 12 cover the two sets of side baffles 9. The drainage gap between the two sections divides the space into two independent chambers. An adjusting rod 13 is fixedly connected to the end of the side baffle 9 furthest from the second float 6. A first rear baffle 19 is fixedly connected to the end of the first collecting net 10 near the adjusting rod 13. A second rear baffle 21 is fixedly connected to the end of the third collecting net 12 near the adjusting rod 13. A first drain plate 20 and a second drain plate 22 are rotatably connected to the first rear baffle 19 and the second rear baffle 21, respectively. The first rear baffle 19 and the first drain plate 20, and the second rear baffle 21 and the second drain plate 22, are all secured by latches 23. The two independent chambers formed by the first collecting net 10, the second collecting net 11, and the third collecting net 12 have an open structure at the end near the second float 6, allowing floating pollutants to directly flow into the chamber; and a closed structure at the end near the adjusting rod 13, sealed by the first drain plate 20 and the second drain plate 22, respectively. Workers can lock and unlock the first drain plate 20 and the second drain plate 22 using the latch 23, thus facilitating the cleaning of pollutants accumulated in the two chambers. One end of the adjusting rod 13 is fixedly connected to a handwheel 14, and an adjusting plate 15 is fixedly connected to the outer wall of the adjusting rod 13 near the handwheel 14. A rod 16 is inserted through the adjusting plate 15. An adjusting slot 17 is opened through the floating frame 1 near the adjusting rod 13. The rod 16 passes through the adjusting plate 15 and the floating frame 1 in sequence and is inserted into the adjusting slot 17. A spring 18 is sleeved on the outside of the rod 16. One end of the spring 18 is fixed to the outer wall of the adjusting plate 15, and the other end of the spring 18 is fixed to the rod 16. When the worker turns the handwheel 14, the side baffle 9, the first collection net 10, the second collection net 11, and the third collection net 12 will rotate synchronously with the handwheel 14 under the transmission drive of the adjusting rod 13. The adjusting rod 13 is fixed to the floating frame 1 by inserting a rod 16. When the rod 16 is simultaneously inserted into both the adjusting plate 15 and the adjusting slot 17, the limiting constraint of the adjusting slot 17 restricts the rotation of the handwheel 14, preventing it from rotating further. The adjusting slot 17 has three insertion holes at different angles, allowing the handwheel 14 to be adjusted and fixed at three different angles. These three adjustment angles correspond to three different operating states of the sewage discharge mechanism. State 1, such as Figure 5As shown, under the buoyancy of the first pontoon 5, the top end face of the second collection net 11 remains flush with the water surface of the channel. The chamber formed by the second collection net 11 and the first collection net 10 is entirely above the water surface. This chamber can centrally collect floating pollutants intercepted and gathered by the second pontoon 6. It should be noted that after long-term operation, if the amount of pollutants accumulated exceeds the capacity of the chamber between the first collection net 10 and the second collection net 11, newly added pollutants will not be able to enter the chamber and will instead remain and gather in the U-shaped structural area enclosed by the second pontoon 6 and the floating frame 1, awaiting centralized cleaning. This structural arrangement can effectively avoid the problem of pollutants overturning the sewage discharge mechanism, ensuring the stability of the channel pollutant interception operation throughout the entire process.

[0029] State 2, such as Figure 6 As shown, the operator first pulls the insertion rod 16 outward to disengage the end of the insertion rod 16 from the limiting constraint of the adjustment slot 17; then, the operator rotates the handwheel 14 to align the insertion rod 16 to the next set of insertion holes in the adjustment slot 17; then, the outward pulling force on the insertion rod 16 is released, and the insertion rod 16 automatically springs back to its original position under the elastic force of the spring 18 and re-inserts into the adjustment slot 17, thus locking the angle of the handwheel 14. After the handwheel 14 is fixed, the top end face of the third collection net 12 is flush with the water surface of the channel, and the entire chamber formed by the separation between the second collection net 11 and the third collection net 12 is located above the water surface. At the same time, the chamber formed by the separation between the first collection net 10 and the second collection net 11 spans the water surface and is inclined towards the adjustment rod 13. At this point, the operator can unlock the latch 23 between the first rear baffle 19 and the first drain plate 20, allowing the pollutants accumulated in the chambers of the first collection net 10 and the second collection net 11 to automatically fall outwards under gravity, achieving rapid cleaning of the pollutants. The overall operation is convenient, efficient, and labor-saving. It should be noted that if the amount of pollutants accumulated during equipment operation exceeds the capacity limit of the chamber between the first collection net 10 and the second collection net 11, the operator can rotate the adjusting rod 13 to tilt the chamber between the first collection net 10 and the second collection net 11. The excess pollutants can then be automatically diverted into the chamber between the second collection net 11 and the third collection net 12 for temporary storage, effectively preventing residual accumulation during the cleaning of large volumes of pollutants and ensuring thorough cleaning.

[0030] State 3, such as Figure 7As shown, based on state two, the operator can continue to rotate the adjusting rod 13 to align and rotate the insertion rod 16 and insert it into the next insertion hole of the adjusting slot 17. After adjustment, both sets of chambers between the first collecting net 10 and the second collecting net 11, and between the second collecting net 11 and the third collecting net 12, are completely detached from the water surface and positioned above it, tilted towards the adjusting rod 13. The operator can then unlock the latch 23 between the second rear baffle 21 and the second sewage discharge plate 22 to thoroughly clean the pollutants remaining in the chambers of the second collecting net 11 and the third collecting net 12, achieving complete removal of pollutants from the sewage discharge mechanism, ensuring no residue or accumulation in the equipment, and facilitating the device's subsequent return to normal interception operations.

[0031] The working principle of the technical solution provided by this invention is as follows: In use, the staff first fixes the nylon ropes at both ends of the float to the banks of the channel, so that the U-shaped outline structure formed by the second float 6 and the floating frame 1 faces the direction of water flow. Under the interception and guidance of the second float 6, the floating pollutants in the channel can continuously accumulate at the floating frame 1 and smoothly flow into the cavity formed by the first collection net 10 and the second collection net 11, realizing the centralized collection of pollutants.

[0032] During long-term continuous operation of the equipment, if the amount of pollutants accumulated exceeds the capacity limit of the chamber between the first collection net 10 and the second collection net 11, subsequent floating pollutants will be unable to continue to enter the chamber. Instead, they will remain stably suspended and gather in the U-shaped structure area enclosed by the second float 6 and the floating frame 1, waiting for subsequent centralized cleaning. This can effectively prevent pollutants from escaping and leaking, and ensure the stability of the interception.

[0033] When cleaning up accumulated pollutants, workers first pull the insertion rod 16 outwards to disengage its end from the limiting constraint of the adjustment slot 17. Then, they rotate the handwheel 14 to align the insertion rod 16 to the next set of insertion holes in the adjustment slot 17. After releasing the insertion rod 16, it automatically springs back to its original position under the elastic force of the spring 18 and is then inserted and fixed inside the adjustment slot 17, completing the angle locking of the handwheel 14. After angle adjustment, the top end face of the third collection net 12 is flush with the channel water surface, and the chamber between the second collection net 11 and the third collection net 12 is entirely above the water surface. Simultaneously, the chamber between the first collection net 10 and the second collection net 11 is arranged across the water and tilted towards the adjustment rod 13. At this point, workers can unlock the latch 23 between the first rear baffle 19 and the first discharge plate 20, allowing the pollutants accumulated in the chambers of the first collection net 10 and the second collection net 11 to automatically fall and be discharged by gravity, achieving rapid pollutant removal. This method is simple, efficient, and labor-saving. If the amount of pollutants accumulated in the early stage is large and exceeds the capacity limit of a single chamber, after the chambers of the first collection net 10 and the second collection net 11 are tilted, the excess pollutants can be automatically diverted and temporarily stored in the chamber between the second collection net 11 and the third collection net 12 to avoid pollutant residue and overflow during the cleaning process.

[0034] After the pollutants in the chambers of the first collection net 10 and the second collection net 11 are cleaned, the operator can continue to rotate the adjusting rod 13 to further align and rotate the insertion rod 16 and insert it into the next insertion hole of the adjusting slot 17. After the secondary adjustment and positioning are completed, the two sets of chambers, the first collection net 10 and the second collection net 11, and the second collection net 11 and the third collection net 12, are completely detached from the water surface and arranged as a whole above the water surface, all tilted towards the adjusting rod 13. The operator can then unlock the latch 23 between the second rear baffle 21 and the second sewage discharge plate 22 to thoroughly clean the residual pollutants temporarily stored in the chambers of the second collection net 11 and the third collection net 12, achieving comprehensive removal of pollutants inside the sewage discharge mechanism, ensuring that the device is free of dirt and residue, guaranteeing the cleanliness and integrity of the equipment, facilitating the device to be put back into normal interception operations, and effectively improving the overall cleaning effect and operational efficiency.
