Description

Technical Field

[0001] The invention relates to the field of river filtration, and in particular to a river filtration device combining a bridge with a water conservancy project. Background Art

[0002] When passing between the two sides of a river, a bridge is usually built on the river. For some narrower rivers or rivers used to transport water for agricultural irrigation, short bridges are usually built. The water flow in such rivers usually has the characteristic of only having a large flow during the agricultural irrigation period and the rainy season.

[0003] For the above-mentioned types of rivers, since their water flow has a certain periodicity, when there is no large flow, duckweed in the river will usually reproduce on a large scale. Once the reproduction of duckweed in the river is not restricted, it will often spread to the downstream of the river, causing the fish in the downstream of the river to die due to lack of oxygen, thereby affecting the ecosystem. At the same time, residents on both sides of the river will salvage duckweed to feed poultry. In this process, residents usually face the risk of wading, which poses certain safety hazards.

[0051] Working principle of the present invention:

[0052] When the present invention is used, first, two fixed speed bumps 3 arranged on the bridge 2 are used to slow down the vehicles passing by. When the vehicle is about to drive onto the bridge 2, the initial speed of the vehicle will be reduced by the fixed speed bumps 3 first. Then, when the vehicle drives onto the bridge 2, the movable speed bumps 4 can be used to slow down the vehicle for a second time, which is helpful to avoid the vehicle from having a large impact on the bridge 2 due to excessive speed. At the same time, the design of the speed bumps can also be used to effectively control the speed of the vehicle on the bridge 2. When the vehicle is driving on the bridge 2, the fixed speed bumps 3 located in the direction of the vehicle will first slow down the vehicle. After the speed of the vehicle is reduced, the movable speed bumps 4 will slow down the vehicle for a second time. After the vehicle passes the bridge 2, there is another fixed speed bump 3. Therefore, when the driver sees this situation, the speed of the vehicle will be effectively reduced before the vehicle passes the fixed speed bumps 3 at both ends, thereby effectively controlling the speed of the vehicle on the bridge 2.

[0053] By setting the movable speed bump 4, when the vehicle that has been initially decelerated by the fixed speed bump 3 contacts the movable speed bump 4, the movable speed bump 4 will slide downward, thereby compressing the damping spring 20, which can perform secondary deceleration on the vehicle on one hand, and on the other hand, the sliding design of the movable speed bump 4 can effectively reduce the impact of the vehicle on the bridge 2. Traditional speed bumps are often directly fixed on the bridge 2, and when the vehicle passes, they are often in rigid contact, so the impact of the vehicle will directly act on the bridge 2 through the speed bump, which can easily cause the speed bump to be quickly damaged and cannot reduce the impact of the vehicle on the bridge 2. By setting the fixed speed bump 3, when the vehicle is traveling on the bridge 2, the vehicle can be initially decelerated, thereby reducing the impact of the vehicle caused by inertia, so that the impact of the vehicle on the bridge 2 is initially reduced by passing the speed bump. When the vehicle is traveling on the movable speed bump 4, by setting the damping spring 20, part of the impact force of the vehicle can be effectively converted into the elastic force of the damping spring 20, so that the work generated by the impact is converted into the internal force of the damping spring 20, thereby achieving the purpose of secondary buffering and further reducing the impact of the vehicle on the bridge 2.

[0054] When a vehicle passes through the movable speed bump 4, the movable speed bump 4 will move downward under the impact of the vehicle and the gravity of the vehicle, thereby driving the transmission slide post 16 to slide downward. When a vehicle passes on one side of the bridge 2, one of the transmission slide posts 16 slides downward, and at this time, the transmission slide post 16 squeezes one end of the cross plate 14, thereby causing the transmission slide post 16 to tilt down. When the transmission slide post 16 tilts down, it will drive the rack 11 to move downward, and in this process, the connection between the rack 11 and the cross plate 14 will rotate relative to the horizontal axis. After the rack 11 moves downward, it will drive the single-turn gear 10 to rotate, thereby driving the conveyor belt 19 to move toward the direction close to the collecting groove 22. When vehicles pass on both sides of the bridge 2, the two transmission slide posts 16 will slide downward, thereby squeezing the cross plate 14 at the same time, causing the cross plate 14 to drop, thereby driving the rack 11 to drop, so as to achieve the purpose of driving the single-turn gear 10 to rotate.

[0055] When the vehicle passes through the movable speed bump 4, the buffer spring 13 is set so that part of the impact generated by the vehicle can be transmitted to the buffer spring 13 through the transmission slide 16, and the buffer spring 13 further releases the impact, thereby further reducing the impact of the vehicle on the bridge 2. The setting of the buffer spring 13 can, on the one hand, reduce the impact on the bridge 2 by releasing the force on the bridge 2 again, which is beneficial to ensuring the service life of the bridge 2. On the other hand, after the vehicle passes through the movable speed bump 4, the buffer spring 13 is beneficial to resetting the cross plate 14, and in the process of resetting the cross plate 14, it is also beneficial to achieve the resetting of the movable speed bump 4.

[0056] When the rack 11 is descending, the single-turn gear 10 drives the conveyor belt 19 to rotate, and when the rack 11 is ascending, the single-turn gear 10 rotates by itself, and the conveyor belt 19 does not rotate.

[0057] When the river channel guides the water, the floating debris or duckweed and other plants on the river surface will be blocked by the screen 6, and then the debris or duckweed and other plants will be gathered on the conveyor belt 19. The setting of the screen 6 can help to block and filter the debris or duckweed and other plants on the river channel, which is helpful to prevent the debris on the river channel from flowing downstream with the water flow, and it can also help to prevent duckweed from flowing downstream with the water flow. Duckweed has a strong reproductive capacity. When the river surface is full of duckweed, the duckweed will isolate the air in the river channel, thereby causing the fish in the river channel to die due to lack of oxygen. The setting of the screen 6 can help to prevent the duckweed in the river channel from reproducing downstream, and by blocking the duckweed, it is helpful to protect the ecological balance of fish in the downstream river channel.

[0058] When there are too many duckweeds in the river, the duckweeds will gather on the conveyor belt 19 with the water flow. When a vehicle passes by the bridge 2, the movable speed bump 4 can gradually transport the duckweeds to the collection tank 22. Then, the duckweeds can be salvaged through the collecting assembly on the river bank 1. By rotating the spiral plate 23, the duckweeds can be gradually transported to the top of the fixed cylinder 9 through the spiral plate 23. After the duckweeds are transported to the top of the spiral plate 23, they will fall into the collecting tank 8, realizing the salvage of the duckweeds. Residents on both sides of the river can collect them through the collecting assembly. The duckweed in the collecting trough 8 is used to feed poultry. At the same time, the spiral plate 23 is provided so that residents can salvage the duckweed on the river bank 1, avoiding water operations, which is beneficial to reducing the risk of residents wading. In addition, through the provision of the spiral plate 23, residents can rotate the spiral plate 23 on the river bank 1 to salvage the duckweed by themselves, which can also reduce the cost of clearing duckweed from the river. In addition, through the salvage by residents, the role of duckweed can also be improved, so that duckweed can be effectively used to feed poultry, and the risk of residents going to the river to salvage duckweed is also reduced.

[0059] The impurities in the collecting tank 22 are salvaged in the same manner as the above-mentioned duckweed salvage method to achieve the salvage of the impurities.

[0060] By setting the lifting base 18, the position of the device can be effectively raised, thereby achieving the shielding of water in the river channel, playing a role similar to that of a reservoir. When the dry season comes, the position of the mounting frame 7 can be raised to limit the water and store water. In the rainy season or the crop irrigation period, the position of the mounting frame 7 can also be appropriately raised to form a height difference in the water in the river below the bridge 2. When the water flows, it is beneficial to convert the potential energy of the water into kinetic energy, thereby achieving the purpose of accelerating the water flow.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
