Abstract
Description
Technical Field
[0001] This invention relates to the field of road surface water drainage technology, and in particular to a sponge city road structure and its usage method for preventing rainwater deposition on the road surface. Background Technology
[0002] With the acceleration of urbanization and the frequent occurrence of extreme rainfall, urban flooding, water shortages, and water environment deterioration have gradually become key bottlenecks restricting sustainable urban development. The concept of sponge city construction has emerged and become an important ecological engineering direction promoted at the national level. As the "blood vessels" of urban infrastructure, the road system's drainage and ecological adaptability are one of the core carriers of sponge city construction.
[0003] Currently, the core requirements of sponge city road structure design have been upgraded from the traditional "rapid drainage" to an integrated function of "infiltration, retention, storage, purification, utilization, and drainage"—it is necessary to reduce the retention time of rainwater on the road surface through permeable pavement structures and drainage systems to avoid traffic safety risks and road surface damage caused by water accumulation; it is also necessary to replenish groundwater resources through rainwater infiltration, reduce rainwater runoff pollution through preliminary purification, and improve the urban water environment; at the same time, it is also necessary to take into account road landscape and ecological compatibility to enhance the overall livability of the city.
[0004] Existing sponge city roads have achieved rainwater infiltration and initial drainage through basic structures such as permeable roadbeds and side drainage ditches. However, significant technical shortcomings still exist in practical applications. Specific problems are as follows: First, road surface water carries impurities such as fallen leaves, household waste, and road mud during its flow. Existing drainage structures lack targeted impurity interception and separation mechanisms. Impurities easily accumulate and clog after entering the drainage channel with rainwater, preventing water from flowing out normally and ultimately causing road surface water to stagnate. Second, while a few structures achieve initial impurity interception, the lack of efficient impurity transport and anti-clogging designs means that intercepted impurities are prone to secondary accumulation in the transport channel, forming new blockage points. Summary of the Invention
[0005] To overcome the above shortcomings, this invention provides a sponge city road structure and usage method that avoids rainwater deposition on the road surface, solving the problem in the prior art that impurities such as fallen leaves and garbage can easily clog the drainage channel, thus preventing water from entering the drainage channel and causing the drainage effect of road surface water to fail.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sponge city road structure to avoid rainwater deposition on the road surface, comprising drainage ditches on both sides of the road and a permeable roadbed on the road surface. The drainage ditches contain uniformly arranged treatment chambers. Each treatment chamber has an inlet trough communicating with its interior on the side closest to the road. Multiple uniformly arranged screen teeth are fixedly connected to the lower side of the inlet trough, and these screen teeth are used to initially intercept impurities in the accumulated water. A transmission rod is rotatably connected to the inner wall of the treatment chamber, and multiple uniformly arranged separating teeth are fixedly connected to the outer wall of the transmission rod. The separating teeth and the screen teeth are arranged alternately. Through the rotation of the transmission rod, the separating teeth are separated... The separator can pick up impurities intercepted by the sieve teeth; a conveying plate is fixedly connected to the inner wall of the processing chamber, and a conveying channel is opened at the top of the conveying plate, with the bottom of the conveying channel being designed at an incline; a discharge trough is opened at the end of the processing chamber, and a storage tank is detachably connected to one side of the discharge trough; one end of the conveying plate extends through the discharge trough to directly above the storage tank, ensuring that impurities can fall directly into the storage tank; multiple drainage channels are evenly opened on the bottom inner wall of the processing chamber, which communicate with the inside of the drainage ditch, and rainwater after impurity separation can be discharged into the drainage ditch through the drainage channels; a hydrodynamic mechanism for providing power to the transmission rod is installed inside the processing chamber.
[0007] As a further description of the above technical solution: the hydrodynamic mechanism includes an upper water storage box, which is slidably connected to the inner wall of the treatment chamber and tightly fitted to the inner wall of the treatment chamber, and can only slide in the vertical direction; the treatment chamber is provided with symmetrically arranged compression springs, the top of which is fixedly connected to the bottom of the upper water storage box for resetting the upper water storage box; the end wall of the upper water storage box is provided with a drainage groove, and a sealing plate is slidably connected to the end wall of the upper water storage box, which is used to control the opening and closing of the drainage groove; a pair of baffles are fixedly connected to the inner end wall of the treatment chamber, and the sealing plate is located between the baffles. When the upper water storage box slides up and down, the baffles can push the sealing plate to move along the groove, thereby realizing the opening and closing of the drainage groove; and a gear is fixedly connected to the top of the upper water storage box, and multiple transmission teeth are evenly fixedly connected to the outer wall of the gear. A ratchet is fixedly connected to one end of the transmission rod, and the teeth of the ratchet mesh with the transmission teeth. The up and down movement of the gear drives the ratchet to rotate in one direction, thereby driving the transmission rod to rotate.
[0008] As a further description of the above technical solution: a lower water storage box is fixedly connected to the bottom inner wall of the processing chamber; the end of the compression spring away from the upper water storage box is fixedly connected to the bottom inner wall of the lower water storage box; the interior of the impurity conveying plate is hollow, and the interior of the impurity conveying plate is connected to the interior of the lower water storage box through a pipe; the inner wall of the impurity conveying channel has multiple symmetrically arranged flushing holes, which are used to connect the interior of the impurity conveying plate with the impurity conveying channel; when the upper water storage box squeezes the rainwater in the lower water storage box downwards, the rainwater can enter the impurity conveying plate through the pipe and spray out from the flushing holes, impacting the impurities in the impurity conveying channel and preventing the impurities from clogging the impurity conveying channel.
[0009] As a further description of the above technical solution: the outer wall of the impurity conveying plate is fixedly connected with a plurality of uniformly arranged comb teeth, which are staggered with the separation teeth, and the comb teeth are inclined; when the separation teeth rotate, the comb teeth can scrape off the impurities adhering to the separation teeth, ensuring that the separation teeth continue to work effectively.
[0010] As a further description of the above technical solution: the bottom of the conveying plate is provided with a plurality of drainage holes that communicate with the interior of the conveying channel; the drainage holes are evenly distributed along the length of the conveying channel, which can drain the water accumulated in the conveying channel and prevent the water from entering the storage tank along with the impurities.
[0011] As a further description of the above technical solution: the inner hole of the flushing hole at one end away from the impurity conveying channel gradually narrows radially at the other end, and the end of the flushing hole near the impurity conveying channel is obliquely opposite the bottom inner wall of the impurity conveying channel; ensuring that the water flow can effectively impact impurities and push them to move towards the impurity storage tank.
[0012] As a further description of the above technical solution: a filter cover with a mesh is fixedly connected to the bottom inner wall of the lower water storage box, and the filter cover is fitted inside the connection between the lower water storage box and the inside of the conveying plate through a pipe; it is used to filter the mud and sand in the rainwater and prevent the mud and sand from entering the conveying plate and clogging the flushing holes.
[0013] As a further description of the above technical solution: curb stones are evenly arranged on both sides of the road, and the curb stones are located between the treatment chambers; used to guide the water on the road surface to flow into the water inlet trough.
[0014] A method for using a sponge city road structure to prevent rainwater deposition on the road surface includes the following steps:
[0015] Step S1: During rainfall, some of the rainwater on the road surface seeps into the ground through the permeable subgrade of the road surface, achieving natural infiltration; the other part flows to both sides of the road under the action of gravity and enters the treatment chamber through the water inlet trough on the side of the treatment chamber closest to the road.
[0016] Step S2: When rainwater flows through the inlet trough, larger impurities such as fallen leaves and household waste in the water are intercepted by the screen teeth on the lower side of the inlet trough, preventing impurities from directly entering the bottom of the treatment chamber and causing blockage, thus initially achieving the separation of rainwater and impurities.
[0017] Step S3: The rainwater entering the treatment chamber acts on the internal hydrodynamic mechanism, causing the hydrodynamic mechanism to generate power and drive the transmission rod to rotate around the inner wall of the treatment chamber. The transmission rod can operate autonomously without the need for external energy.
[0018] Step S4: When the transmission rod rotates, the separation teeth on its outer wall rotate together. Since the separation teeth and the screen teeth are arranged in an alternating manner, the separation teeth can pick up the impurities intercepted by the screen teeth and carry them away from the screen teeth. Subsequently, the impurities fall into the impurity conveying channel at the top of the impurity conveying plate under the action of gravity. With the help of the inclined design at the bottom of the impurity conveying channel, the impurities slide along the channel towards the end of the processing chamber.
[0019] Step S5: The sliding impurities pass through the discharge chute at the end of the processing chamber and finally fall into the storage tank that is detachably connected to the discharge chute for collection; while the rainwater after the impurities are separated flows into the drainage ditch through the drainage chute on the inner wall of the bottom of the processing chamber, so as to achieve the orderly discharge of rainwater.
[0020] Step S6: When the impurities in the storage tank accumulate to a certain amount, disassemble the storage tank and clean the internal impurities. After cleaning, reinstall the storage tank to ensure the continuous and stable operation of the structure.
[0021] As a further description of the above technical solution: a method for using a sponge city road structure to avoid rainwater deposition on the road surface includes the following steps:
[0022] Step S1: During rainfall, rainwater on the road surface flows towards the drainage ditch under the guidance of the curb stones on both sides of the road; some rainwater infiltrates into the ground through the permeable subgrade on the road surface to replenish groundwater, and another part of the rainwater enters the treatment chamber through the inlet trough on the side of the treatment chamber closest to the road, completing the initial collection of surface water on the road.
[0023] Step S2: When the rainwater entering the inlet tank flows through the screen teeth, larger impurities such as fallen leaves and household waste in the water are intercepted by the evenly arranged screen teeth, thus initially separating the rainwater from the impurities; the filtered rainwater passes through the gaps between the screen teeth and falls into the upper water storage box in the treatment chamber.
[0024] Step S3: As the rainwater in the upper water storage box gradually increases, its gravity overcomes the elastic force of the compression spring and slides downward along the inner wall of the treatment chamber. During the sliding process, the sealing plate on the end wall of the upper water storage box contacts the lower baffle and is pushed to open the drain channel. The rainwater in the upper water storage box is discharged through the drain channel, some of the rainwater flows into the lower water storage box, and the rest of the rainwater directly enters the drainage ditch through the drainage channel at the bottom of the treatment chamber. After the rainwater is discharged, the weight of the upper water storage box is reduced, and it resets upward under the action of the compression spring. During the reset process, the sealing plate contacts the upper baffle and is pushed to close the drain channel. The upper water storage box accumulates water again, forming a reciprocating sliding motion. The reciprocating sliding of the upper water storage box drives the top gear to move up and down synchronously. The transmission teeth on the outer wall of the gear drive the meshing ratchet to rotate in one direction, thereby driving the transmission rod to rotate continuously around the inner wall of the treatment chamber.
[0025] Step S4: When the transmission rod rotates, the separation teeth on its outer wall rotate together. Because the separation teeth and the screen teeth are arranged in an alternating manner, the separation teeth pick up the impurities intercepted by the screen teeth and carry them away from the screen teeth. When the rotating separation teeth pass through the comb teeth on the outer wall of the impurity conveying plate, the inclined comb teeth scrape off the impurities adhering to the separation teeth. Under the action of gravity, the impurities fall into the impurity conveying channel at the top of the impurity conveying plate. With the help of the inclined design at the bottom of the impurity conveying channel, the impurities slide along the channel towards the end of the processing chamber.
[0026] Step S5: When the upper water storage box slides down, it squeezes the rainwater in the lower water storage box. After being filtered by the filter cover at the bottom of the lower water storage box, the rainwater enters the hollow impurity conveying plate through the pipe. The rainwater in the impurity conveying plate is sprayed out from the impurity flushing holes on the inner wall of the impurity conveying channel, impacting the impurities in the impurity conveying channel and pushing the impurities towards the discharge trough. The water accumulated in the impurity conveying channel is discharged through the drain holes at the bottom of the impurity conveying plate.
[0027] Step S6: After rinsing and draining, the impurities fall into the detachable storage tank through the discharge chute at the end of the treatment chamber and are collected; all the rainwater after the impurities are separated in the treatment chamber eventually flows into the drainage ditch, realizing the orderly discharge of rainwater.
[0028] Step S7: When impurities accumulate to a certain amount in the storage tank, disassemble the storage tank and clean the internal impurities; regularly check whether the filter cover is blocked by mud and sand, and clean or replace it if necessary to ensure the continuous and stable operation of each structure.
[0029] The present invention has the following beneficial effects:
[0030] 1. In this invention, the integrated structure of initial interception of impurities by sieve teeth, scooping up of impurities by separation teeth, conveying of impurities by conveying channels, and collection of impurities by storage bins can effectively separate and remove impurities such as fallen leaves and garbage from the accumulated water, completely avoiding impurities from clogging the drainage channel and ensuring stable drainage function; at the same time, the weight of the accumulated water itself drives the upper water storage box to move up and down reciprocally, which in turn drives the transmission rod to rotate through the gear and ratchet, without the need for additional electricity or mechanical power, the power source is synchronized with the accumulated water, and the response is timely.
[0031] 2. In this invention, the combination of the lower water storage box, the impurity conveying plate, and the impurity flushing hole utilizes the squeezed accumulated water to form a high-pressure water flow to impact impurities in the impurity conveying channel, preventing impurities from accumulating and clogging in the impurity conveying channel and ensuring smooth impurity conveying; the comb teeth can clean and separate impurities adhering to the teeth, the drain holes can separate impurities from accumulated water, and the filter cover can filter mud and sand. The multi-structure collaboration ensures the thoroughness of impurity separation, conveying, and collection, reducing subsequent maintenance costs. Attached Figure Description

[0040] 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.
[0041] Reference Figure 1-6 This invention provides an embodiment of a sponge city road structure that avoids rainwater deposition on the road surface. The structure includes drainage ditches 1 on both sides of the road and a permeable roadbed 2 on the road surface. The drainage ditches 1 contain uniformly arranged treatment chambers 3. Each treatment chamber 3 has an inlet trough 4 connected to its interior on the side closest to the road. Multiple uniformly arranged screen teeth 5 are fixedly connected to the lower side of the inlet trough 4. A transmission rod 6 is rotatably connected to the inner wall of the treatment chamber 3. Multiple uniformly arranged separation teeth 7 are fixedly connected to the outer wall of the transmission rod 6. The separation teeth 7 and the screen teeth 5... The processing chamber 3 is arranged in an alternating pattern. The inner wall of the processing chamber 3 is fixedly connected with a conveying plate 8. The top of the conveying plate 8 is provided with a conveying channel 9. The bottom of the conveying channel 9 is designed to be inclined. The end of the processing chamber 3 is provided with a discharge trough 10. A storage tank 11 is detachably connected to one side of the discharge trough 10. One end of the conveying plate 8 extends through the discharge trough 10 to the top of the storage tank 11. The bottom inner wall of the processing chamber 3 is evenly provided with a plurality of drainage troughs 12 that communicate with the inside of the drainage ditch 1. The interior of the processing chamber 3 is provided with a hydrodynamic mechanism for providing power to the transmission rod 6.
[0042] The hydrodynamic mechanism includes an upper water storage box 13, which is slidably connected to the inner wall of the treatment chamber 3. The treatment chamber 3 is equipped with symmetrically arranged compression springs 14. The top of the compression springs 14 is fixedly connected to the bottom of the upper water storage box 13. The end wall of the upper water storage box 13 has a drain groove 15. The end wall of the upper water storage box 13 is slidably connected to a sealing plate 16. The inner end wall of the treatment chamber 3 is fixedly connected to a pair of baffles 17. The sealing plate 16 is located between the baffles 17. The top of the upper water storage box 13 is fixedly connected to a gear 18. The outer wall of the gear 18 is evenly fixedly connected to multiple transmission teeth 19. One end of the transmission rod 6 is fixedly connected to a ratchet 20. The teeth of the ratchet 20 mesh with the transmission teeth 19.
[0043] During use, the water inlet troughs 4 on the permeable roadbed 2 and the treatment chamber 3 simultaneously discharge the accumulated water from the road surface. After entering the treatment chamber 3, the water passes through the screen teeth 5 and falls into the upper water storage box 13. Impurities such as fallen leaves and garbage are blocked by the screen teeth 5. As more water enters the upper water storage box 13, the weight of the upper water storage box 13 increases, and the upper water storage box 13 begins to compress the spring 14, moving downwards along the inner wall of the treatment chamber 3. As the upper water storage box 13 moves, the baffle 17 located below the sealing plate 16 inside the treatment chamber 3 will block the sealing plate 16. As the upper water storage box 13 continues to move downwards, the sealing plate 16, due to being blocked, will move relative to the end wall of the upper water storage box 13, thus ceasing to seal the drain channel 15. At this time, the water in the upper water storage box 13 gradually flows out from the drain channel 15, causing the upper water storage box 13 to begin to reset and move upwards under the elastic force of the compression spring 14. After the upper water storage box 13 moves upwards, the baffle 17 located on the upper side of the sealing plate 16 in the treatment chamber 3 will block the sealing plate 16 again, causing the sealing plate 16 to move and seal the drain channel 15 again. The upper water storage box 13 moves up and down repeatedly in this cycle. After being discharged from the drain trough 15, the water is discharged into the drainage ditch 12 at the bottom of the treatment chamber 3. The movement of the upper water storage box 13 synchronously drives the rack 18 to move, which in turn drives the transmission gear 19 to move. The transmission gear 19 meshes with the gear of the ratchet 20. However, it should be noted that the ratchet 20 is a unidirectional transmission component. Only when the transmission gear 19 descends with the rack 18 can it drive the transmission rod 6 to rotate through the ratchet 20. The rotation synchronously drives the separation teeth 7 to rotate. The separation teeth 7 are arranged alternately with the screen teeth 5. Therefore, the rotation of the separation teeth 7 will pick up the impurities on the screen teeth 5. As the separation teeth 7 rotates, the impurities will fall into the impurity conveying channel 9 on the impurity conveying plate 8. The bottom inner wall of the impurity conveying channel 9 is inclined. The impurities will move along the inclined inner wall of the impurity conveying channel 9, so that the impurities fall into the impurity storage tank 11 after passing through the impurity discharge trough 10, thus completing the collection and storage of impurities. This prevents impurities in the water from clogging the drainage trough 12 and causing the water on the road to be unable to be discharged.
[0044] Preferred, such as Figures 2 to 6 As shown, a lower water storage box 21 is fixedly connected to the bottom inner wall of the processing chamber 3. The end of the compression spring 14 away from the upper water storage box 13 is fixedly connected to the bottom inner wall of the lower water storage box 21. The interior of the conveying plate 8 is hollow, and the interior of the conveying plate 8 is connected to the interior of the lower water storage box 21 through a pipe. The inner wall of the conveying channel 9 is provided with a plurality of symmetrically arranged flushing holes 22. The flushing holes 22 are used to connect the interior of the conveying plate 8 with the conveying channel 9.
[0045] During use, impurities, after falling onto the impurity conveying plate 8, will fall into the impurity conveying channel 9 opened at the top of the impurity conveying plate 8. Some of the water discharged from the drain trough 15 opened on the upper water storage box 13 will fall into the lower water storage box 21, so that the lower water storage box 21 stores water. As the upper water storage box 13 moves downward, the bottom of the upper water storage box 13 will insert into the lower water storage box 21, and as the upper water storage box 13 continues to move downward, the bottom of the upper water storage box 13 will squeeze the water in the lower water storage box 21. Because the interior of the lower water storage box 21 is connected to the interior of the impurity conveying plate 8 through a pipe, the water that is squeezed in the lower water storage box 21 will enter the interior of the impurity conveying plate 8 through the pipe. Because the water is squeezed, it has a certain pressure. After entering the interior of the impurity conveying plate 8, it is discharged from the impurity flushing hole 22 and impacts the impurities in the impurity conveying channel 9, pushing the impurities towards the impurity storage tank 11, thereby preventing the impurities from clogging and accumulating in the impurity conveying channel 9, which would prevent the impurity conveying channel 9 from being unable to convey impurities.
[0046] Preferred, such as Figure 4 As shown, the outer wall of the impurity conveying plate 8 is fixedly connected with a plurality of uniformly arranged comb teeth 23. The comb teeth 23 and the separation teeth 7 are arranged alternately, and the comb teeth 23 are inclined. In use, when the transmission rod 6 drives the separation teeth 7 to rotate, because the comb teeth 23 and the separation teeth 7 are arranged alternately, the screen teeth 5 will circulate between the separation teeth 7, thereby pushing out the impurities stuck and blocked on the separation teeth 7, so that the impurities fall into the impurity conveying channel 9 along the inclined comb teeth 23.
[0047] Preferred, such as Figure 6 As shown, the bottom of the impurity conveying plate 8 is provided with multiple drainage holes 24 that communicate with the interior of the impurity conveying channel 9. In use, the water used to impact impurities discharged from the impurity flushing hole 22 can flow out of the drainage hole 24 to the bottom of the processing chamber 3 after impacting the impurities, and then be discharged into the drainage ditch 1 from the drainage trough 12, preventing water from entering the impurity storage tank 11 along with the impurities.
[0048] Preferred, such as Figure 6 As shown, the inner diameter of the flushing hole 22 gradually narrows radially from one end away from the impurity conveying channel 9, and the end of the flushing hole 22 closest to the impurity conveying channel 9 is obliquely aligned with the bottom inner wall of the impurity conveying channel 9. According to the definition of a narrow tube, the flow velocity increases when the water flows from a wide area to a narrow area. The design of the flushing hole 22 gradually narrowing can increase the flow velocity of the discharged water, increase the impact force, and increase the impact effect on impurities. Furthermore, the oblique alignment of the flushing hole 22 with the inner wall of the impurity conveying channel 9 can further increase the impact effect of the discharged water on impurities, causing them to move.
[0049] Preferred, such as Figure 5As shown, a filter cover 26 with a mesh is fixedly connected to the bottom inner wall of the lower water storage box 21. The filter cover 26 covers the connection between the lower water storage box 21 and the inside of the conveying plate 8 through a pipe. The filter cover 26 filters the water entering the inside of the conveying plate 8 to prevent mud and sand from entering the inside of the conveying plate 8 and causing the flushing hole 22 to become blocked.
[0050] Preferred, such as Figure 1 As shown, curb stones 25 are evenly arranged on both sides of the road, and the curb stones 25 are located between the treatment chambers 3; the curb stones 25 can block the water on the road surface and guide the water to the inlet trough 4.
[0051] To further explain the above embodiments, the present invention also provides a method for using a sponge city road structure to avoid rainwater deposition on the road surface. The specific steps for using this sponge city road structure for rainwater treatment are as follows:
[0052] Step S1: During rainfall, rainwater on the road surface flows towards the drainage ditch 1 under the guidance of the curb stones 25 on both sides of the road; some rainwater infiltrates into the ground through the permeable roadbed 2 on the road surface to replenish groundwater, and another part of the rainwater enters the treatment chamber 3 through the water inlet trough 4 on the side of the treatment chamber 3 near the road, completing the initial collection of surface water on the road.
[0053] Step S2: When the rainwater entering the inlet tank 4 flows through the screen teeth 5, larger impurities such as fallen leaves and domestic waste in the water are intercepted by the evenly arranged screen teeth 5, thus initially achieving the separation of rainwater and impurities; the filtered rainwater passes through the gaps between the screen teeth 5 and falls into the upper water storage box 13 in the treatment chamber 3.
[0054] Step S3: As the amount of rainwater in the upper water storage box 13 gradually increases, its gravity overcomes the elastic force of the compression spring 14 and slides downward along the inner wall of the treatment chamber 3. During the sliding process, the sealing plate 16 on the end wall of the upper water storage box 13 contacts the lower baffle 17 and is pushed to open the drain channel 15. The rainwater in the upper water storage box 13 is discharged through the drain channel 15. Some of the rainwater flows into the lower water storage box 21, and the rest of the rainwater directly enters the drainage ditch 1 through the drainage channel 12 at the bottom of the treatment chamber 3. After the rainwater is discharged, the weight of the upper water storage box 13 is reduced, and it resets upward under the action of the elastic force of the compression spring 14. During the reset process, the sealing plate 16 contacts the upper baffle 17 and is pushed to close the drain channel 15. The upper water storage box 13 accumulates water again, forming a reciprocating sliding motion. The reciprocating sliding motion of the upper water storage box 13 drives the top gear 18 to move up and down synchronously. The transmission teeth 19 on the outer wall of the gear 18 drive the meshing ratchet 20 to rotate in one direction, thereby driving the transmission rod 6 to rotate continuously around the inner wall of the treatment chamber 3.
[0055] Step S4: When the transmission rod 6 rotates, the separation teeth 7 on its outer wall rotate together. Because the separation teeth 7 and the sieve teeth 5 are arranged in an alternating manner, the separation teeth 7 pick up the impurities intercepted by the sieve teeth 5 and carry them away from the sieve teeth 5. When the rotating separation teeth 7 passes the comb teeth 23 on the outer wall of the impurity conveying plate 8, the inclined comb teeth 23 (alternating with the separation teeth 7) scrape off the impurities adhering to the separation teeth 7. Under the action of gravity, the impurities fall into the impurity conveying channel 9 at the top of the impurity conveying plate 8. With the help of the inclined design at the bottom of the impurity conveying channel 9, the impurities slide along the channel towards the end of the processing chamber 3.
[0056] Step S5: When the upper water storage box 13 slides down, it squeezes the rainwater in the lower water storage box 21. After being filtered by the filter cover 26 at the bottom of the lower water storage box 21, the rainwater enters the hollow impurity conveying plate 8 through the pipe. The rainwater in the impurity conveying plate 8 is sprayed out from the impurity flushing hole 22 on the inner wall of the impurity conveying channel 9, impacting the impurities in the impurity conveying channel 9 and pushing the impurities to move towards the impurity discharge trough 10. The water accumulated in the impurity conveying channel 9 is discharged through the drain hole 24 at the bottom of the impurity conveying plate 8.
[0057] Step S6: After rinsing and draining, the impurities fall into the detachably connected storage tank 11 through the discharge trough 10 at the end of the treatment chamber 3 to complete the collection; all the rainwater after the impurities are separated in the treatment chamber 3 (including the rainwater directly discharged through the drainage trough 12 and the rainwater discharged through the drain hole 24) finally flows into the drainage ditch 1 to achieve the orderly discharge of rainwater.
[0058] Step S7: When impurities accumulate to a certain amount in the storage tank 11, disassemble the storage tank 11 and clean the internal impurities; regularly check whether the filter cover 26 is blocked by mud and sand, and clean or replace it if necessary to ensure the continuous and stable operation of each structure.
[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. A method for using a sponge city road structure to avoid rainwater deposition on the road surface, characterized in that: Includes the following steps: Step S1: During rainfall, some of the rainwater on the road surface seeps into the ground through the permeable roadbed (2) on the road surface, realizing natural infiltration of rainwater; the other part flows to both sides of the road under the action of gravity and enters the interior of the treatment chamber (3) through the water inlet trough (4) on the side of the road near the treatment chamber (3); Step S2: When rainwater flows through the inlet tank (4), larger impurities such as fallen leaves and domestic waste in the water are intercepted by the screen teeth (5) on the lower side of the inlet tank (4), preventing impurities from directly entering the bottom of the treatment chamber (3) and causing blockage, thus initially achieving the separation of rainwater and impurities; Step S3: The rainwater entering the treatment chamber (3) acts on the internal hydrodynamic mechanism, causing the hydrodynamic mechanism to generate power and drive the transmission rod (6) to rotate around the inner wall of the treatment chamber (3). The transmission rod (6) can operate autonomously without external energy. Step S4: When the transmission rod (6) rotates, the separation teeth (7) on its outer wall rotate together. Since the separation teeth (7) and the sieve teeth (5) are arranged in an alternating manner, the separation teeth (7) can pick up the impurities intercepted by the sieve teeth (5) and carry them away from the sieve teeth (5). Subsequently, the impurities fall into the impurity conveying channel (9) at the top of the impurity conveying plate (8) under the action of gravity. With the help of the inclined design at the bottom of the impurity conveying channel (9), the impurities slide along the channel towards the end of the processing chamber (3). Step S5: The sliding impurities pass through the discharge trough (10) at the end of the processing chamber (3) and finally fall into the storage bucket (11) which is detachably connected to the discharge trough (10) to complete the collection; while the rainwater after the impurities are separated flows into the drainage ditch (1) through the drainage trough (12) on the bottom inner wall of the processing chamber (3) to achieve the orderly discharge of rainwater; Step S6: When the impurities in the storage tank (11) accumulate to a certain amount, disassemble the storage tank (11) and clean the internal impurities. After cleaning, reinstall the storage tank (11) to ensure the continuous and stable operation of the structure.
10. The method of using a sponge city road structure to avoid rainwater deposition on the road surface according to claim 9, characterized in that: Includes the following steps: Step S1: During rainfall, rainwater on the road surface flows towards the drainage ditch (1) under the guidance of the curb stones (25) on both sides of the road; some rainwater infiltrates into the ground through the permeable roadbed (2) on the road surface to replenish groundwater, and another part of the rainwater enters the treatment chamber (3) through the water inlet trough (4) on the side of the road, completing the initial collection of surface water on the road. Step S2: When the rainwater entering the inlet tank (4) flows through the screen teeth (5), larger impurities such as fallen leaves and domestic waste in the water are intercepted by the evenly arranged screen teeth (5), thus initially separating the rainwater from the impurities; the filtered rainwater passes through the gaps in the screen teeth (5) and falls into the upper water storage box (13) in the treatment chamber (3); Step S3: As the amount of rainwater in the upper water storage box (13) gradually increases, its gravity overcomes the elastic force of the compression spring (14) and slides downward along the inner wall of the treatment chamber (3); during the sliding process, the sealing plate (16) on the end wall of the upper water storage box (13) contacts the lower baffle (17), and after being pushed, it opens the drain channel (15), and the rainwater in the upper water storage box (13) is discharged through the drain channel (15), some of the rainwater flows into the lower water storage box (21), and the rest of the rainwater directly enters the drainage ditch (1) through the drainage channel (12) at the bottom of the treatment chamber (3); rainwater discharge After exiting, the weight of the upper water storage box (13) is reduced, and it resets upward under the elastic force of the compression spring (14). During the reset process, the sealing plate (16) contacts the upper baffle (17), and after being pushed, it closes the drain channel (15). The upper water storage box (13) accumulates water again, forming a reciprocating sliding. The reciprocating sliding of the upper water storage box (13) drives the top gear (18) to move up and down synchronously. The transmission teeth (19) on the outer wall of the gear (18) drive the meshing ratchet (20) to rotate in one direction, thereby driving the transmission rod (6) to rotate continuously around the inner wall of the treatment chamber (3). Step S4: When the transmission rod (6) rotates, the separation teeth (7) on its outer wall rotate together. Because the separation teeth (7) and the sieve teeth (5) are arranged in an alternating manner, the separation teeth (7) pick up the impurities intercepted by the sieve teeth (5) and carry them away from the sieve teeth (5). When the rotating separation teeth (7) pass through the comb teeth (23) on the outer wall of the conveying plate (8), the inclined comb teeth (23) scrape off the impurities adhering to the separation teeth (7). Under the action of gravity, the impurities fall into the conveying channel (9) at the top of the conveying plate (8). With the help of the inclined design at the bottom of the conveying channel (9), the impurities slide along the channel towards the end of the processing chamber (3). Step S5: When the upper water storage box (13) slides down, it squeezes the rainwater in the lower water storage box (21). After the rainwater is filtered by the filter cover (26) at the bottom of the lower water storage box (21), it enters the hollow impurity conveying plate (8) through the pipe. The rainwater in the impurity conveying plate (8) is sprayed out from the impurity flushing hole (22) on the inner wall of the impurity conveying channel (9), impacting the impurities in the impurity conveying channel (9) and pushing the impurities to move towards the discharge trough (10). The water in the impurity conveying channel (9) is discharged through the drain hole (24) at the bottom of the impurity conveying plate (8). Step S6: After rinsing and draining, the impurities fall into the detachable storage tank (11) through the discharge trough (10) at the end of the treatment chamber (3) to complete the collection; all the rainwater after the impurities are separated in the treatment chamber (3) finally flows into the drainage ditch (1) to achieve the orderly discharge of rainwater. Step S7: When the impurities in the storage tank (11) accumulate to a certain amount, disassemble the storage tank (11) and clean the internal impurities; regularly check whether the filter cover (26) is blocked by mud and sand, and clean or replace it if necessary to ensure that each structure continues to operate stably.
