Description

Technical Field

[0001] This invention relates to the field of river management technology, and in particular to a river pollution prevention and control device and method. Background Technology

[0002] As open waterways, rivers often have floating debris such as plastic, leaves, and weeds on their surface. These pollutants not only affect the aesthetics of the river but also impact water quality. Therefore, it is necessary to clean up these pollutants. Current methods for cleaning river pollutants mainly rely on manual labor, which is labor-intensive and inefficient. Another method involves using floats and filters to intercept floating pollutants before manual collection and removal. While this method can intercept pollutants, it still requires manual labor and is relatively inefficient.

[0003] Existing patent CN202410050956.6 discloses a water conservancy river channel pollution interception and flood control device, including piers cast into the riverbank, a crossbeam between two piers, a pollution interception component at the lower part of the crossbeam, and a pollution cleaning mechanism installed at the pollution interception component. Each of the two piers has a vertical column, and a horizontal mounting plate is located between the two vertical columns. A drive mechanism is installed on the horizontal mounting plate, which drives the pollution interception component and the pollution cleaning mechanism. The pollution interception component intercepts pollution in the river channel, and the pollution cleaning mechanism cleans the intercepted pollution to the riverbank, facilitating removal of the pollution by workers. The drive mechanism drives both the pollution interception component and the cleaning mechanism, saving significant manpower and improving river cleaning efficiency. However, the structure of this patent is relatively complex, and the pollution interception net needs to be lifted to clean the pollutants. During the lifting process, the net cannot continue its pollution interception operation, affecting the pollution cleaning effect. Summary of the Invention

[0037] Example

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, a river pollution control device includes a pollutant collection mechanism 1, which collects pollutants. The collection mechanism 1 is located on the riverbank side of the river for easy installation. A guide mechanism 2 is located in front of the collection mechanism 1 to intercept and guide pollutants into the collection mechanism 1. The guide mechanism 2 intercepts pollutants in the river and directs them to the collection mechanism 1 on the riverbank. A conveying mechanism 3 is located behind the collection mechanism 1 to discharge the pollutants, eliminating the need for manual pollutant collection and reducing labor costs.

[0039] like Figure 4 , Figure 5 , Figure 6As shown. The collection mechanism 1 includes a base 11, which is fixed to the bottom of the river channel. A top rod 14 is provided above the base 11, and the base 11 and the top rod 14 are fixedly connected by a first support rod 12 and a second support rod 13. The base 11, the top rod 14, the first support rod 12, and the second support rod 13 can be made of corrosion-resistant steel as needed. A filter plate for intercepting pollutants is fixedly installed between the first support rod 12 and the second support rod 13 on the same side. The filter plate intercepts pollutants and ensures the smooth passage of river water, thereby improving the pollutant interception effect. A filter plate is fixedly installed between the two second support rods 13, where the filter plate must avoid the baffle 33 on the conveyor belt 32 and the lever 16 on the rotating belt 15.

[0040] A toggle mechanism is provided between the top rods 14 to move pollutants. The toggle mechanism includes a first rotating shaft and a second rotating shaft arranged in parallel. The two ends of the first rotating shaft are rotatably connected to the first support rod 12 via bearings. The two ends of the second rotating shaft are rotatably connected to the second support rod 13 via bearings. A first pulley is fixedly mounted on the first rotating shaft, and a second pulley is fixedly mounted on the second rotating shaft. The first pulley and the second pulley are connected by a rotating belt 15. Two rotating belts 15 are arranged in parallel, and several levers 16 are evenly arranged on the rotating belts 15. The levers 16 are arranged in parallel between the rotating belts 15 and are fixedly connected to the rotating belts 15. The rotating belts 15 drive the levers 16 to rotate, and the levers 16 collect pollutants on the river surface and move the pollutants forward, delivering the pollutants to the conveying mechanism 3, which then delivers the pollutants out of the river.

[0041] The guiding mechanism 2 includes a first guiding unit and a second guiding unit arranged opposite to each other. The length of the first guiding unit is greater than that of the second guiding unit, thereby guiding pollutants to one side of the river channel. The first guiding unit includes a first fixing seat 22, which is fixed to the bottom of the river channel. One end of the first fixing seat 22 is fixedly connected to a first fixing pile 21, which is fixed to the riverbed on one side of the river channel. The other end of the first fixing seat 22 is fixedly connected to a base 11. A first top plate 23 is provided above the first fixing seat 22. One end of the first top plate 23 is fixedly connected to the first fixing pile 21, and the other end is fixedly connected to a top rod 14. A filter screen 24 for intercepting pollutants is fixedly installed between the first fixing pile 21 and the first support rod 12. The filter screen 24 intercepts pollutants in the river channel, allowing river water to pass through the filter screen 24 smoothly.

[0042] like Figure 7As shown, several guide structures are arranged in a linear array between the first top plate 23 and the first fixed seat 22. Each guide structure includes a mounting rod 27, with both ends of the rod fixedly connected to an upper mounting seat 25 and a lower mounting seat 26, respectively. The upper mounting seat 25 is fixedly mounted on the first top plate 23, and the lower mounting seat 26 is fixedly mounted on the first fixed seat 22. A sleeve 29 is slidably mounted on the mounting rod 27. The inner diameter of the sleeve 29 is larger than that of the mounting rod 27, allowing the sleeve 29 to slide along the rod 27 to adapt to different water levels. A floating turntable 28 is fixedly mounted on the sleeve 29. The turntable 28 is made of a float plate material, making it lightweight and able to float on the water surface, thus improving the guiding and conveying effect of pollutants on the water surface.

[0043] Several guide components are evenly arranged on the edge of the turntable 28. Each guide component includes rollers 212, with both ends of the rollers 212 rotatably mounted on connecting ears 211, which are fixed to the turntable 28. The distance between adjacent turntables 28 is precisely sufficient to allow the rollers 212 to rotate. The rollers 212 drive the pollutants to move between the turntables 28, thus smoothly guiding and transporting the pollutants to the collection mechanism 1, preventing them from clogging the filter screen 24.

[0044] Several spiral blades 210 are evenly fixed on the sleeve 29 to drive the sleeve 29 to rotate. Under the action of water flow, the spiral blades 210 drive the turntable 28 to rotate through the sleeve 29, thereby guiding and transporting pollutants on the water surface.

[0045] The second guiding unit includes a second fixing seat, which is fixed to the bottom of the river channel. One end of the second fixing seat is fixedly connected to a second fixing pile 213, which is fixed to the riverbed on the other side of the river channel. The other end of the second fixing seat is fixedly connected to a base 11. A second top plate 214 is provided above the second fixing seat. One end of the second top plate 214 is fixedly connected to the second fixing pile 213, and the other end of the second top plate 214 is fixedly connected to a top rod 14. A filter screen 24 for intercepting pollutants is provided between the second fixing seat and the second top plate 214. The filter screen 24 and the filter plate form a relatively closed filtration structure, which improves the interception effect of pollutants.

[0046] The conveying mechanism 3 includes a conveyor belt 32, which is inclinedly positioned between two push rods 14. The drive shaft at the bottom of the conveyor belt 32 is rotatably connected to the second support rod 13 via bearings. The bottom of the conveyor belt 32 is located below the drive belt, thus smoothly lifting the pollutants conveyed by the lever 16. The drive shaft at the top of the conveyor belt 32 is rotatably connected to the column 31 via bearings. The column 31 is fixedly connected to the base 11 and the push rods 14. Several baffles 33 for lifting pollutants are evenly fixedly arranged on the conveyor belt 32. A protective plate is fixedly arranged between the push rods 14, the column 31, and the base 11 to protect the pollutants on the conveyor belt 32, preventing them from falling into the river and causing pollution to the downstream river. The conveyor belt 32 is a permeable belt, allowing water contained in the pollutants to flow downwards during the transport process, reducing the water content of the pollutants.

[0047] A discharge structure is provided below the top of the conveyor belt 32. The discharge structure includes a collection hopper 34, which is located directly below the top of the conveyor belt 32. The collection hopper 34 is fixed to the column 31. A conveying pipe 35 is provided at the bottom of the collection hopper 34. A rotating shaft 36 is rotatably installed inside the conveying pipe 35, and a spiral conveying blade 37 for conveying pollutants is fixedly installed on the rotating shaft 36. A motor 38 is provided outside the conveying pipe 35 to drive the rotating shaft 36. Several drainage holes are evenly provided at the bottom of the conveying pipe 35, so that the moisture contained in the pollutants can flow out from the conveying pipe 35 during the conveying process. A discharge port 39 is provided at one end of the conveying pipe 35, through which the pollutants are discharged into the river. A pollutant collection box can be installed below the discharge port 39.

[0048] A first drive wheel 310 is fixedly mounted on one end of the rotating shaft 36, and a second drive wheel 311 is fixedly mounted on the drive shaft at the top of the conveyor belt 32. The first drive wheel 310 and the second drive wheel 311 are connected by a first drive belt. A third drive wheel 312 is fixedly mounted on the drive shaft at the bottom of the conveyor belt 32, and a fourth drive wheel 17 is fixedly mounted on the second rotating shaft of the rotating belt 15. The third drive wheel 312 and the fourth drive wheel 17 are connected by a second drive belt. The rotating shaft 36 drives the conveyor belt 32 to rotate via the first drive wheel 310, the second drive wheel 311, and the first drive belt. The conveyor belt 32 drives the rotating belt 15 to rotate via the third drive wheel 312, the fourth drive wheel 17, and the second conveyor belt 32, thus enabling the synchronous rotation of the conveyor blades 37, the conveyor belt 32, and the lever 16, simplifying the structure.

[0049] The pollution control method of the above-mentioned river pollution control device includes the following steps:

[0050] S1. The water flow in the river channel drives the sleeve 29 to rotate through the spiral blade 210. The sleeve 29 drives the turntable 28 to rotate. The turntable 28 drives the roller 212 to rotate through the connecting ear 211. During the rotation, the roller 212 and the turntable 28 transport pollutants in the river channel to the collection mechanism 1.

[0051] S2. Motor 38 drives rotating shaft 36 to rotate. Rotating shaft 36 drives conveyor belt 32 to rotate through first transmission wheel 310 and second transmission wheel 311. Conveyor belt 32 drives rotating belt 15 to rotate through third rotating wheel and fourth transmission wheel 17. Rotating belt 15 drives lever 16 to rotate. Lever 16 pushes pollutants toward conveying mechanism 3.

[0052] S3, the conveyor belt 32 lifts the pollutants upward through the baffle 33, and the conveyor belt 32 sends the pollutants into the collection hopper 34. The pollutants in the collection hopper 34 are transported outward along the conveying pipe 35 under the action of the conveying blades 37, and then discharged into the river through the discharge port 39.

[0053] Therefore, the river pollution prevention and control device and method described in this invention can solve the problem of poor pollutant removal effect of existing river pollution interception devices.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
