Description

Technical Field

[0001] This invention relates to the field of road drainage filtration technology, specifically to an anti-clogging road drainage filtration structure. Background Technology

[0002] Road drainage is a facility that combines road engineering to remove rainwater and snowmelt from the road surface 1, urban wastewater, groundwater, and lower the groundwater level. In order to prevent water accumulation on urban roads during rain, rainwater drainage pipes are usually installed on both sides of the road, and drainage outlets are opened on both sides of the road. Rainwater on the road surface 1 will enter the drainage channel 2 from the drainage outlets, and finally be discharged into rivers and lakes after collection. There are usually fences in the drainage outlets to block larger debris in the water.

[0003] For the sake of urban greening and aesthetics, large trees or green belts are now planted along both sides of the road. When plants reach a certain season, a large number of leaves will fall off. During rain, the impact of rainwater on the leaf surface will accelerate the leaf fall, resulting in more leaves on the ground after rain. If the rain is heavy, the rainwater will carry the leaves along with it as it flows towards the drain. The drain gates are easily blocked by the leaves in the water. Then the leaves will accumulate until the entire drain is blocked. At this time, a large area of ​​water will accumulate around the drain, which will seriously affect the passage of pedestrians. Moreover, the accumulated leaves cannot be dispersed on their own, and sanitation workers must manually pick up the leaves from the surface of the gate.

[0004] Based on this, the present invention designs an anti-clogging road drainage filtration structure to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-clogging road drainage filtration structure to solve the problems of the shortcomings of the prior art mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging road drainage and filtration structure, comprising a road surface, a drainage channel, a movable fence, a reset component for resetting the movable fence, and a collection component for collecting leaves. A drainage channel is formed in the middle of the road surface, and a drainage outlet is formed on the left end face of the drainage channel. A fixed frame is fixedly installed inside the drainage outlet, and a movable frame is slidably installed laterally inside the fixed frame. A movable fence is rotatably installed inside the movable frame. Limit blocks are fixedly installed on both the front and rear faces of the movable fence. The front end of the fixed frame... The upper and lower ends of the drainage channel are provided with limiting grooves. The limiting block is slidably installed in the limiting grooves. The height of the limiting grooves is the same as the height of the limiting block. The right end of the limiting groove is connected to a rotating groove. The diameter of the rotating groove is equal to the diagonal length of the limiting block. The collection assembly includes a collection groove, a mounting frame, a lower support plate, and a rotating assembly for rotating the lower support plate. The right end of the drainage channel is provided with a collection groove. The mounting frame is fixedly installed on the upper end of the drainage channel. The lower support plate is rotatably installed in the mounting frame. The front end and rear end of the fixed frame are provided with permeable grooves.

[0007] As a further embodiment of the present invention, the reset assembly includes a counterweight plate, a first transmission rack and a second transmission rack. A vertical groove is provided on the lower end face of the inner cavity of the collection groove. The counterweight plate is vertically slidably installed in the vertical groove. The first transmission rack is fixedly installed on the rear end face of the counterweight plate. The second transmission rack is fixedly installed on the rear end face of the movable frame. The first transmission rack and the second transmission rack are connected by gear transmission.

[0008] As a further embodiment of the present invention, the rotating assembly includes a rotating gear and a rotating rack. The rotating gear is fixedly installed on the front end face of the rotating shaft of the lower support plate, and the rotating rack that meshes with the rotating gear is fixedly installed on the front end face of the counterweight plate. A support block is fixedly installed on the left side of the lower end face of the mounting frame.

[0009] As a further embodiment of the present invention, the surface of the lower support plate is provided with water-permeable holes;

[0010] As a further embodiment of the present invention, an energy storage gear is fixedly installed on the rear end face of the limiting block located at the rear end face of the movable fence, an installation frame is installed on the rear end face of the installation frame, an energy storage rack is slidably installed on the left end face of the installation frame, and an energy storage spring is fixedly installed between the left end face of the energy storage rack and the right end face of the installation frame.

[0011] As a further embodiment of the present invention, a sliding groove is provided on the rear end face of the mounting frame, the sliding groove is connected to the inner cavity of the mounting frame, the right end of the mounting bracket is vertically slidably installed in the sliding groove, and a float is fixedly installed on the front end face of the mounting bracket, the float being located in the inner cavity of the mounting frame.

[0012] As a further embodiment of the present invention, an mounting plate is fixedly mounted on the upper end face of the inner cavity of the mounting frame, and a plurality of top rods are fixedly mounted on the lower end face of the mounting plate;

[0013] As a further embodiment of the present invention, the push rod is arc-shaped, and the push rod and the rotating groove are concentric.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] By rotating the movable fence onto the movable frame, and then sliding the movable frame laterally onto the fixed frame, when leaves accumulate to a certain level on the left side of the movable fence, water pressure will push the movable frame and fence to the right. This will gradually expose the permeable channels on the front and rear sides of the fixed frame. Rainwater that previously could only pass through the movable fence into the drainage channel can now enter through the permeable channels on both sides of the fixed frame. This ensures the drainage efficiency of the outlet and prevents it from becoming completely blocked, which would eventually lead to blockage. At this point, the water flow... The system will push the movable fence and frame to continue moving to the right. After the limiting block enters the limiting groove, the water flow will push the movable fence to rotate counterclockwise. The leaves and debris on the left side of the movable fence will flow to the upper surface of the lower support plate under the influence of the water flow. Then, when the movable frame resets, the lower support plate will rotate clockwise, carrying the leaves into the collection trough. This process clears the leaves and debris when the movable fence is blocked, preventing large amounts of water from accumulating on the road and ensuring normal pedestrian passage. The cleared leaves and debris will be collected in the collection trough for convenient disposal by sanitation workers.

[0016] The counterweight plate acts as the driving force for the movable frame to reset. When the movable frame moves to the right, the counterweight plate rises. The rising counterweight plate can block the left end of the collection tank after the lower support plate rotates to a horizontal position. This prevents water from rushing into the collection tank quickly and scattering the leaves already collected in the tank. The surface of the lower support plate has permeable holes, so that when water enters the installation frame, it can pass through the permeable holes into the drainage channel, giving the water a certain degree of fluidity. Under the action of the water flow, more leaves and other debris can be brought into the lower support plate. Furthermore, under the action of the water flow, the leaves and other debris will be firmly pressed against the upper end of the lower support plate, ensuring that the leaves and other debris will not move to the left again.

[0017] An installation plate is fixedly installed on the upper end face of the inner cavity of the installation frame, and multiple push rods are fixedly installed on the lower end face of the installation plate. When the movable fence rotates counterclockwise, the multiple push rods will be inserted into multiple water-permeable gaps on the surface of the movable fence, pushing the accumulated leaves in the water-permeable gaps out from the left side of the movable fence. At the same time, the multiple push rods will block the water-permeable gaps, so that the water flow can only pass through the lower end face of the movable fence. This increases the water flow speed passing under the movable fence, ensuring that the water flow can carry all the accumulated leaves on the left side of the movable fence to the lower support plate. At the same time, when the leaves follow the water flow into the lower support plate, some leaves will be scattered in the water. Blocking the water-permeable gaps can also prevent the leaves from passing through the water-permeable gaps and returning to the left side of the movable fence, ensuring the cleaning effect.

Implementation

[0031] 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.

[0032] Please see Figure 1-10 This invention provides a technical solution: an anti-clogging road drainage and filtration structure, including a road surface 1, a drainage channel 2, a movable fence 3, a reset component for resetting the movable fence 3, and a collection component for collecting leaves. The drainage channel 2 is located in the middle of the road surface 1, and a drainage outlet is located on the left end face of the drainage channel 2. A fixed frame 4 is fixedly installed inside the drainage outlet, and a movable frame 5 is laterally slidably installed inside the fixed frame 4. The movable fence 3 is rotatably installed inside the movable frame 5. Limiting blocks 6 are fixedly installed on both the front and rear faces of the movable fence 3. The front and rear faces of the fixed frame 4 are both open... A limiting groove 7 is provided, and a limiting block 6 is slidably installed in the limiting groove 7. The height of the limiting groove 7 is the same as the height of the limiting block 6. The right end of the limiting groove 7 is connected to a rotating groove 8. The diameter of the rotating groove 8 is equal to the diagonal length of the limiting block 6. The collection component includes a collection groove 9, a mounting frame 10, a lower support plate 11, and a rotating component for rotating the lower support plate 11. The right end face of the drainage channel 2 is provided with a collection groove 9. The mounting frame 10 is fixedly installed on the upper end face of the drainage channel 2. The lower support plate 11 is rotatably installed in the mounting frame 10. The front end face and the rear end face of the fixed frame 4 are both provided with permeable grooves 12.

[0033] Traditional drainage gates are very easy to get clogged by leaves in the water. The leaves will accumulate and accumulate until the entire drainage gate is blocked. At this time, a large area of ​​water will accumulate around the drainage gate, which will seriously affect the passage of pedestrians. In addition, the accumulated leaves cannot be dispersed on their own, and sanitation workers must pick up the leaves on the surface of the gate by hand.

[0034] At work, such as Figure 1-4 As shown, this device installs the movable fence 3 in the movable frame 5, and then slides the movable frame 5 laterally to the fixed frame 4. When the movable fence 3 is blocked by leaves, the thrust on its left end increases. Since the limiting block 6 is located in the limiting groove 7, the movable fence 3 cannot rotate. Then, under the thrust of the water flow, the movable frame 5 will move the movable fence 3 to the right within the fixed frame 4. Figure 8 As shown, the permeable channels 12 located on the front and rear faces of the fixed frame 4 will gradually be exposed. Rainwater, which originally could only pass through the movable fence 3 to enter the drainage channel 2, can now enter the drainage channel 2 through the permeable channels 12 on both sides of the fixed frame 4. This ensures the drainage efficiency of the drainage outlet and prevents the outlet from being completely blocked. The reason why the permeable channels 12 are exposed only after the movable fence 3 is blocked is that when the rain is not heavy, the rainwater will also carry a small amount of floating debris towards the drainage outlet. If the movable fence 3 is always retracted inside the fixed frame 4, the floating debris in the water will accumulate on the left side of the fixed frame 4. In the corner between the end face and the left end face of the movable frame 5, sanitation workers cannot easily see the accumulated debris. As the debris accumulates, it affects the drainage efficiency of the drain outlet. To facilitate cleaning by sanitation workers, the left end face of the movable fence 3 is flush with the left end face of the fixed frame 4 until a certain amount of debris accumulates on its left side. When the movable frame 5 begins to move to the right, exposing the permeable trough 12, if there are still leaves in the water, they will begin to accumulate towards the permeable trough 12, eventually blocking it. The water flow will then push the movable fence 3 and the movable frame 5 further to the right. Figure 8 As shown, the limiting blocks 6 on both sides of the movable fence 3 move to the right into the rotating groove 8, at which point the limiting blocks 6 can rotate freely within the rotating groove 8. Figure 9As shown, the right end face of the movable frame 5 is in contact with the left end face of the mounting frame 10, and the rotating component rotates the lower support plate 11 to a horizontal state. At this time, the water flow will push the movable fence 3 to rotate counterclockwise. Then, the accumulated material on the lower left side of the movable fence 3 will flow to the lower support plate 11 and the collection tank 9 under the action of the water flow. After the accumulated material under the movable fence 3 is sent away by the water flow, the movable fence 3 will rotate to a vertical downward state under its own gravity. During the process of the movable frame 5 moving to the right, the reset component will start to store energy. At this time, the reset component will start to push the movable frame 5 to the left to reset. At the same time, the rotating component will drive the lower support plate 11 to rotate clockwise. The lower support plate 11 can send all the accumulated material on its upper end face into the collection tank 9. This completes the collection of accumulated material such as leaves. At the same time, after the movable frame 5 drives the movable fence 3 to reset, the movable fence 3 can pass water with maximum efficiency.

[0035] This device can clear accumulated debris such as leaves when the movable fence 3 is blocked, preventing a large amount of water from accumulating on the road surface 1, ensuring the normal passage of pedestrians, and collecting all the cleared debris in the collection trough 9 for convenient centralized disposal by sanitation workers.

[0036] As a further embodiment of the present invention, the reset assembly includes a counterweight plate 13, a first transmission rack 14 and a second transmission rack 15. A vertical groove 16 is provided on the lower end face of the inner cavity of the collection groove 9. The counterweight plate 13 is vertically slidably installed in the vertical groove 16. The first transmission rack 14 is fixedly installed on the rear end face of the counterweight plate 13. The second transmission rack 15 is fixedly installed on the rear end face of the movable frame 5. The first transmission rack 14 is transmitted to the first transmission rack 15 through gear transmission.

[0037] When working, if the activity box 5 is moved to the right, as follows: Figure 6 As shown, the second transmission rack 15 on the rear end face of the movable frame 5 will also move to the right, as... Figure 2 As shown, the second transmission rack 15 will then drive the first transmission rack 14 to rise via the gear, so that the counterweight plate 13 as a whole will rise in the vertical groove 16. The vertical groove 16 is located on the left side of the lower surface of the collection groove 9, because when the movable frame 5 moves to the right, as... Figure 9 As shown, the lower support plate 11 located on the left end face of the collection tank 9 will rotate counterclockwise to a horizontal state, thus opening the entire left end face of the collection tank 9. Since the water flow will then carry the leaves quickly to the right, if the left end face of the collection tank 9 is in an open state, the water flow will quickly enter the collection tank 9, and the leaves originally collected in the collection tank 9 may be dispersed by the water flow and enter the movable frame 5 or the fixed frame 4. Figure 8As shown, the rising counterweight plate 13 can block the left end face of the collection tank 9 after the lower support plate 11 rotates to a horizontal state, thus preventing water from rushing into the collection tank 9 quickly. At the same time, when the movable frame 5 resets to the left, the counterweight plate 13 can provide the force required for the movable frame 5 to reset using its own gravity.

[0038] As a further embodiment of the present invention, the rotating assembly includes a rotating gear 17 and a rotating rack 18. The rotating gear 17 is fixedly installed on the front end face of the rotating shaft of the lower support plate 11, and the rotating rack 18 that meshes with the rotating gear 17 is fixedly installed on the front end face of the counterweight plate 13. A support block 19 is fixedly installed on the left side of the lower end face of the mounting frame 10.

[0039] At work, such as Figure 7 As shown, when the counterweight plate 13 rises, it drives the rotating gear 17 to rotate counterclockwise through the rotating rack 18 in front of it. In this way, the lower support plate 11 can rotate from a vertical state to a horizontal state. The function of the support block 19 is to support the lower end face of the lower support plate 11. Because the lower support plate 11 only needs to rotate 90 degrees, but the counterweight plate 13 has a large upward stroke, after the rotating gear 17 rotates 90 degrees, the rotating rack 18 will disengage from the rotating gear 17. At this time, the support block 19 is needed to support the lower end face of the lower support plate 11.

[0040] As a further embodiment of the present invention, the surface of the lower support plate 11 is provided with water-permeable holes 20;

[0041] At work, such as Figure 9 As shown, the permeable holes 20 on the surface of the lower support plate 11 are designed to allow water to flow in a certain direction. When the water flows and moves the leaf accumulation on the left side of the movable fence 3 from below the movable fence 3 to the lower support plate 11, if there were no permeable holes 20 on the surface of the lower support plate 11, the water would fill the interior of the movable frame 5 and the mounting frame 10. However, the water would lack fluidity and would not be able to bring more leaf accumulation into the mounting frame 10. But after the permeable holes 20 are opened on the surface of the lower support plate 11, the water will enter the drainage channel 2 through the permeable holes 20 after entering the mounting frame 10. This gives the water fluidity, and the water flow can bring more leaf accumulation into the lower support plate 11. The leaves and other accumulations will be firmly pressed against the upper surface of the lower support plate 11, ensuring that the leaves and other accumulations will not move to the left again.

[0042] As a further aspect of the present invention, an energy storage gear 21 is fixedly installed on the rear end face of the limiting block 6 located at the rear end face of the movable fence 3, and an installation frame 22 is installed on the rear end face of the installation frame 10. An energy storage rack 23 is slidably installed on the left end face of the installation frame 22, and an energy storage spring 24 is fixedly installed between the left end face of the energy storage rack 23 and the right end face of the installation frame 22. During operation, when leaves gather on the left end face of the movable fence 3, they are not concentrated in one pile, but are distributed in a right-angled triangle. The closer to the movable fence 3, the higher the pile will be. If the movable fence 3 is rotated by the thrust of water, after most of the leaves have passed under the movable fence 3, the thrust of the water flow on the left surface of the movable fence 3 will decrease rapidly. At this time, the movable fence 3 will return to a vertical downward state, which may cause some leaves to be blocked on the left side of the movable fence 3. Figure 6 As shown, we install the mounting bracket 22 on the rear end face of the mounting frame 10, and then install the energy storage rack 23 on the left end face of the mounting bracket 22 through the energy storage spring 24. When the movable frame 5 and the movable fence 3 move to the right, since the movable fence 3 cannot rotate, the energy storage gear 21 on the rear end face of the movable fence 3 will push the energy storage rack 23 to move to the right. Then the energy storage spring 24 will be compressed until the limit block 6 enters the rotating groove 8. The compressed energy storage spring 24 will push the energy storage rack 23 to move to the left. Then the energy storage gear 21 and the movable fence 3 will start to rotate counterclockwise. The energy storage spring 24 provides a counterclockwise rotation force to the movable fence 3, so that the movable fence 3 can always maintain a rightward offset state, so that all the leaves gathered on the left side of the movable fence 3 can pass under the movable fence 3, ensuring that all the leaves gathered on the left side of the movable fence 3 can be collected.

[0043] As a further embodiment of the present invention, a sliding groove 25 is provided on the rear end face of the mounting frame 10, the sliding groove 25 communicates with the inner cavity of the mounting frame 10, the right end of the mounting bracket 22 is vertically slidably installed in the sliding groove 25, and a float 26 is fixedly installed on the front end face of the mounting bracket 22, the float 26 being located in the inner cavity of the mounting frame 10.

[0044] During operation, after the energy storage spring 24 drives the energy storage gear 21 to rotate via the energy storage rack 23, the movable fence 3 will always remain tilted to the right, as shown. Figure 8As shown, because the limiting block 6 rotates at a certain angle within the rotating groove 8, it cannot enter the limiting groove 7 from the rotating groove 8. The movable fence 3 must be reset to a vertically downward position before the limiting block 6 can re-enter the limiting groove 7. This allows the movable frame 5 and the movable fence 3 to move to the left and reset. To reset the movable fence 3, the energy storage rack 23 must be separated from the energy storage gear 21. When the water flows with leaves onto the lower support plate 11, although the lower support plate 11 has permeable holes 20 on its surface, the water will carry a large number of leaves gathered on the left side of the movable fence 3 onto the lower support plate 11. This will cause the permeable holes 20 on the surface of the lower support plate 11 to be largely blocked. The water cannot quickly pass through the permeable holes 20 into the drainage channel 2, and the water will accumulate in the fixed frame 4, the movable frame 5, and the mounting frame 10. As the water level in the mounting frame 10 rises, such as Figure 10 As shown, when water comes into contact with the float 26, the water gives the float 26 an upward buoyancy. Under the action of buoyancy, the float 26 will drive the mounting bracket 22 and the energy storage rack 23 to rise. In this way, the energy storage rack 23 can disengage from the energy storage gear 21, and then the energy storage gear 21 can rotate freely. The movable fence 3 will rotate clockwise to a vertical downward position. At this time, there are no more leaves gathered on the left side of the movable fence 3, and the movable fence 3 will be pushed to the right and will drop significantly. Then the counterweight plate 13 will be lowered by gravity. Under the action, it will begin to descend. The first transmission rack 14 on the rear side of the counterweight plate 13 will drive the second transmission rack 15 to move to the left through the gear. Then the movable frame 5 will begin to reset to the left. At the same time, the lower support plate 11 will begin to rotate clockwise. When the counterweight plate 13 is completely inserted into the vertical groove 16, the movable frame 5 has just completed its reset. At the same time, the lower support plate 11 has just rotated to a vertical position. All the leaves on the surface of the lower support plate 11 will slide into the collection groove 9. This completes the cleaning and collection of surface deposits on the movable fence 3.

[0045] As a further embodiment of the present invention, an mounting plate 27 is fixedly mounted on the upper end face of the inner cavity of the mounting frame 10, and a plurality of push rods 28 are fixedly mounted on the lower end face of the mounting plate 27. The push rods 28 are arc-shaped and have the same center as the rotating groove 8.

[0046] When the leaves gather on the left side of the movable fence 3 during operation, some leaves may get stuck in the permeable gaps on the surface of the movable fence 3. Figure 3 As shown, an mounting plate 27 is installed on the upper end face of the inner cavity of the mounting frame 10, and then a top rod 28 is fixedly installed on the lower end face of the mounting plate 27. During the counterclockwise rotation of the movable fence 3, the limiting block 6 will definitely be located in the rotating groove 8, which means that the movable fence 3 rotates with the center of the rotating groove 8 as its rotation center. Since the top rod 28 and the rotating groove 8 are concentric, when the movable fence 3 rotates counterclockwise, as shown... Figure 9As shown, multiple push rods 28 will be inserted into multiple permeable gaps on the surface of the movable fence 3, pushing the accumulated leaves in the permeable gaps of the movable fence 3 out from the left side of the movable fence 3. At the same time, the multiple push rods 28 will block the permeable gaps, so that the water flow can only pass through the lower end of the movable fence 3. This increases the water flow speed passing under the movable fence 3, ensuring that the water flow can carry all the accumulated leaves on the left side of the movable fence 3 to the lower support plate 11. At the same time, when the leaves follow the water flow into the lower support plate 11, some leaves will be scattered in the water. Blocking the permeable gaps can also prevent the leaves from passing through the permeable gaps and returning to the left side of the movable fence 3, ensuring the cleaning effect.
