Description

Technical Field

[0001] The present invention relates to an urban road, and more particularly to a sponge urban road. Background Art

[0002] Sponge cities, also known as "water-resilient cities," are internationally known as "low-impact development rainwater systems." These systems absorb, store, infiltrate, and purify water during rain, releasing the stored water for use when needed. New roads or renovated urban hardened roads undergo permeable pavement renovations, using techniques such as new permeable paving materials, pre-buried rapid drainage pipes, and adjusting the elevations of roads and green belts to prevent rainwater from stagnating on roads. However, current urban road drainage relies primarily on grates to quickly drain accumulated water. When roads are lined with abundant vegetation, fallen leaves, especially during the rainy season, can be quickly removed. If these leaves are not promptly cleared, especially during strong winds and heavy rain, they can be washed down by rainwater and flow toward the grates. When these leaves or debris clog the grates, their drainage rate decreases, leading to significant accumulation of water on the roads and ultimately causing rainwater to stagnate, posing a safety hazard to drivers. Summary of the Invention

[0003] The purpose of the present invention is to provide a sponge city road, which can quickly drain water after the water grates on the road surface are blocked, thereby avoiding rainwater retention on the road surface.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: comprising a road surface, a curb, a water grate, and a rainwater pipe, wherein a mounting port for mounting the water grate is provided on one side above the rainwater pipe, at least one drain port is provided in the center of the water grate, a grate plate is provided inside the drain port, a water storage tank is provided at the bottom of the grate plate, a plurality of drain holes are provided at the bottom of the water storage tank, a guide pipe is provided on the side of the water storage tank close to the water grate, an overflow port is provided at the upper end of the guide pipe, the overflow port is higher than the water grate, a floating plate is provided inside the water storage tank, a top rod is provided between the floating plate and the grate plate, and the top rod passes through the water storage tank and the rainwater pipe;

[0005] When the water grate is blocked: the water level rises and flows into the water tank through the overflow port, the floating plate floats up, and the push rod lifts the grate plate to quickly discharge the accumulated water and debris on the road through the drain port;

[0006] After the floating plate is raised: the water discharge rate of the drain hole is less than the water inlet rate of the overflow port. After the water on the road drops below the overflow port, the drain hole discharges the water tank, and the floating plate and the grate plate fall back to their original position.

[0007] By adopting the above technical solution, after the water grate is blocked with the grate plate, the water level on the road surface rises to the overflow port, and the rainwater enters the interior of the diversion pipe through the overflow port, and then enters the interior of the water tank through the diversion pipe. The internal water level of the water tank gradually rises, and a floating plate is provided inside the water tank. The buoyancy of the floating plate is greater than the downward force, so that the grate plate is lifted up through the top rod provided between the floating plate and the grate plate, and the top rod passes through the water tank and the rainwater pipe, and the drain port is opened.

[0008] The present invention is further configured as follows: the curbstone is configured to protrude outward from the road surface, and the water grate is installed in a groove of the curbstone.

[0009] By adopting the above technical solution, the curbstone is protruding outward from the road surface to form an outward convex structure, and the water grate is installed in the groove of the curbstone. The road surface is prevented from being damaged by vehicles during driving, and at the same time, it can play a certain guiding role for rainwater, making it easier for rainwater to gather in the direction of the groove.

[0010] The present invention is further configured as follows: the grate plate is a circular structure, the inner wall of the drain port is integrally formed with a flange, the inner diameter of the flange is smaller than the outer diameter of the grate plate, and the interior of the drain port is also integrally formed with a plurality of reinforcing ribs in a ring shape.

[0011] By adopting the above technical solution, the circular structure of the grate plate is conducive to the rapid assembly with the drain outlet when the grate plate falls, and the inner diameter of the drain outlet is larger than the outer diameter of the grate plate to prevent the grate plate and the drain outlet from interfering with each other when falling. The six reinforcing ribs integrally formed inside the drain outlet can improve the supporting strength of the drain outlet on the grate plate.

[0012] The present invention is further configured such that: a through hole and a symmetrically provided guide hole are provided at the geometric center of each of the reinforcing rib and the grate plate, the guide hole and the through hole are connected, guide plates are symmetrically installed on both sides of the upper end of the mandrel, and a top plate is symmetrically installed on both sides of the lower end of the mandrel;

[0013] The two guide plates are smaller than the radial distance between the two top plates;

[0014] The guide holes on the grate plate are adapted to the guide plate;

[0015] The guide holes on the reinforcement ribs are adapted to the top plate.

[0016] By adopting the above technical solution, the two guide plates are smaller than the radial distance between the two top plates, the guide holes on the grate plate are adapted to slide with the guide plates, and the guide holes on the reinforcing ribs are adapted to slide with the top plate. When the upper end of the top plate passes through the guide hole and rests on the top of the grate plate, the grate plate can be lifted up. At the same time, the upper end of the top rod is exposed to the water surface. At this time, the cleaning personnel can quickly find the position of the water grate and then clean up the surrounding debris. It also serves as a warning, warning passers-by that this is the drainage area.

[0017] The present invention is further configured such that a reflective sticker is attached to the upper end of the top rod.

[0018] By adopting the above technical solution, a reflective tape is pasted on the end of the top rod exposed on the grate plate. At night, the vehicle's driving lights shine on the reflective tape, thereby enhancing the warning effect of the top rod and facilitating timely discovery at night. At the same time, it can remind the vehicle driver that this is the edge of the road, avoiding the wheel hitting the curb due to the inability to see the road conditions clearly during driving.

[0019] The present invention is further configured as follows: an outer sleeve is provided between the water grate and the rainwater pipe, and the top rod, the guide plate and the top plate are sleeved in the outer sleeve.

[0020] By adopting the above technical solution, the top rod, guide plate and top plate are arranged in the outer sleeve to prevent garbage from adhering to the surface of the top rod, guide plate and top plate when water flows through the rainwater pipe, thereby improving the smoothness of the up and down sliding of the top rod, guide plate and top plate.

[0021] The present invention is further configured as follows: a water pipe is installed at the bottom of the water storage tank and directly below the drain hole, and the water pipe and the rainwater pipe converge into an underground rainwater storage tank.

[0022] By adopting the above technical solution, the water pipe and the rainwater pipe are connected to the underground pre-buried water storage tank using a conventional pipe connection method, and the collected rainwater is introduced into the water storage tank and then recycled for secondary reuse.

[0023] The present invention is further configured such that: the guide plate and the guide plate portion of the push rod are both made of rubber material.

[0024] By adopting the above technical solution, when the top rod and the guide plate are lifted up by the floating plate, when a vehicle or pedestrian accidentally collides with them, damage to the vehicle and pedestrian is avoided, while at the same time, the guide plate and the top rod are ensured not to be broken.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The grate plate can move up and down along the plumb line under the joint action of the floating plate and the water tank. When it rises, the drain port opens, which can quickly clean up larger debris. When the grate plate fits the water grate, the drain port closes and the water is discharged normally. Finally, the accumulated water and debris on the road surface can be quickly cleaned up. Repeated drainage can be achieved without human intervention to prevent urban road waterlogging.

[0027] 2. The water grate is installed in the groove of the curb to prevent vehicles from crushing the water grate during driving. At the same time, it can guide the rainwater to a certain extent, so that the rainwater can be concentrated in the direction of the groove.

[0028] 3. The upper end of the top rod extends out of the water surface, and a reflective sticker is pasted on the upper end of the top rod. At night, the vehicle's driving lights shine on the reflective sticker, which enhances the warning effect of the top rod, making it easier for cleaning personnel to find the position of the water grate in time. At the same time, it can remind vehicle drivers that this is the edge of the road, avoiding the wheels hitting the curb due to the inability to see the road conditions clearly during driving.

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0059] Example: Figure 1-17As shown, a sponge city road includes a pavement 1, a curb 2, a water grate 3, and a rainwater pipe 4. A mounting port 41 for mounting the water grate 3 is provided on one side above the rainwater pipe 4. At least one drain port 31 is provided in the center of the water grate 3. The diameter of the drain port 31 is larger than the drainage diameter of the water grate 3, which is conducive to quickly cleaning larger debris from the pavement 1. A grate plate 32 is installed inside the drain port 31. The grate plate 32 can move up and down along the direction of the plumb line. When it rises, the drain port 31 opens and can For quick cleaning of larger debris, when the grate plate 32 is in contact with the water grate 3, the drain port 31 is closed and the water is discharged normally. A water storage tank 35 is installed at the bottom of the grate plate 32. A plurality of drain holes 351 are provided at the bottom of the water storage tank 35. The drain holes 351 can discharge the accumulated water in the water storage tank 35 to ensure that the water storage tank 35 is in a water-free state under normal circumstances. A guide pipe 36 is installed on one side of the water storage tank 35 close to the water grate 3. An overflow port 361 is provided at the upper end of the guide pipe 36. The overflow port 361 is higher than the water grate. After the grate 3 is blocked with the grate plate 32, the water level of the road surface 1 rises to the overflow port 361, and the rainwater enters the interior of the guide pipe 36 through the overflow port 361, and then enters the interior of the water storage tank 35 through the guide pipe 36. The water level inside the water storage tank 35 gradually rises, and a floating plate 37 is set inside the water storage tank 35. The buoyancy of the floating plate 37 is greater than the downward force, so that the water passes through the top rod 33 set between the floating plate 37 and the grate plate 32, and penetrates the water storage tank 35 and the rainwater pipe 4 through the top rod 33. , lift the grate plate 32, at this time the drain port 31 is opened, when the water grate 3 is blocked, the water level rises and flows into the water tank 35 through the overflow port 361, the floating plate 37 floats up, and the push rod 33 lifts the grate plate 32 to quickly discharge the accumulated water and debris on the road surface 1 through the drain port 31. After the floating plate 37 rises, the water discharge rate of the drain hole 351 is lower than the water inlet rate of the overflow port 361. After the water accumulated on the road surface 1 drops below the overflow port 361, the drain hole 351 discharges the water tank 35, and the floating plate 37 and the grate plate 32 fall and return to their original position.

[0060] The curbstone 2 is protruding outward from the road surface 1 , and the water grate 3 is installed in the groove of the curbstone 2 .

[0061] like Figure 1 As shown, the curb 2 is protruding outward from the road surface 1 to form an outwardly convex structure, and the water grate 3 is installed in the groove of the curb 2 to prevent the vehicle from crushing the water grate 3 during driving. At the same time, it can play a certain guiding role on the rainwater, making it easier for the rainwater to gather in the direction of the groove.

[0062] The grate plate 32 is a circular structure. The inner wall of the drain port 31 is integrally formed with a flange 311 . The inner diameter of the flange 311 is smaller than the outer diameter of the grate plate 32 . A plurality of reinforcing ribs 5 are also integrally formed in an annular shape inside the drain port 31 .

[0063] like Figure 12As shown, the circular structure of the grate plate 32 is conducive to the rapid assembly of the grate plate 32 with the drain port 31 when the grate plate 32 falls, and the inner diameter of the drain port 31 is larger than the outer diameter of the grate plate 32 to prevent the grate plate 32 from interfering with the drain port 31 when falling. Figure 11 The six reinforcing ribs 5 integrally formed inside the drain port 31 can improve the supporting strength of the drain port 31 on the grate plate 32.

[0064] A through hole 321 and a symmetrically arranged guide hole 322 are provided at the geometric center of the reinforcing rib 5 and the grate plate 32. The guide hole 322 is connected to the through hole 321. Guide plates 331 are symmetrically installed on both sides of the upper end of the top rod 33, and top plates 34 are symmetrically installed on both sides of the lower end of the top rod 33. The two guide plates 331 are smaller than the radial distance between the two top plates 34. The guide hole 322 on the grate plate 32 is adapted to the guide plate 331, and the guide hole 322 on the reinforcing rib 5 is adapted to the top plate 34.

[0065] like Figure 11 and 12 As shown, the two guide plates 331 are smaller than the radial distance between the two top plates 34, the guide holes 322 on the grate plate 32 are adapted to slide with the guide plates 331, and the guide holes 322 on the reinforcing ribs 5 are adapted to slide with the top plates 34, as shown in FIG. Figure 17 As shown, when the upper end of the top plate 34 passes through the guide hole 322 and rests on the top of the grate plate 32, the grate plate 32 can be lifted up. At the same time, the upper end of the top rod 33 is exposed to the water surface. At this time, the cleaning personnel can quickly find the position of the water grate 3 and then clean up the surrounding debris. It also serves as a warning to passers-by that this is a drainage area.

[0066] A reflective sticker 332 is attached to the upper end of the top rod 33 .

[0067] like Figure 6 As shown, a reflective sticker 332 is pasted on the end of the top rod 33 exposed on the grate plate 32. At night, the vehicle's driving lights shine on the reflective sticker 332, which enhances the warning effect of the top rod 33 and facilitates timely discovery at night. At the same time, it can remind the vehicle driver that this is the edge of the road surface 1, avoiding the wheel hitting the curb 2 due to the inability to see the road surface 1 clearly during driving.

[0068] An outer sleeve 6 is provided between the water grate 3 and the rainwater pipe 4 , and the top rod 33 , the guide plate 331 and the top plate 34 are sleeved in the outer sleeve 6 .

[0069] like Figure 10 As shown, the top rod 33, the guide plate 331 and the top plate 34 are sleeved in the outer sleeve 6 to prevent garbage from adhering to the surfaces of the top rod 33, the guide plate 331 and the top plate 34 when water flows through the rainwater pipe 4, thereby improving the smoothness of the up and down sliding of the top rod 33, the guide plate 331 and the top plate 34.

[0070] A water pipe 7 is installed at the bottom of the water storage tank 35 and is placed directly below the drain hole 351. The water pipe 7 and the rainwater pipe 4 converge into the underground rainwater storage tank.

[0071] The water pipe 7 and the rainwater pipe 4 are connected to the underground pre-buried water tank using a conventional pipe connection method, and the collected rainwater is introduced into the water tank and then recycled for secondary reuse.

[0072] The guide plate 331 and the guide plate 331 portion of the push rod 33 are both made of rubber.

[0073] When the push rod 33 and the guide plate 331 are lifted up by the floating plate 37 , when a vehicle or pedestrian accidentally collides with them, damage to the vehicle or pedestrian is avoided, while ensuring that the guide plate 331 and the push rod 33 are not broken.

[0074] Working principle: Figure 1 For example, when there is no water on the road surface 1, under the action of gravity, the grate plate 32 is moved to the inside of the drain port 31, and the floating plate 37 is placed at the bottom of the water storage tank 35. At this time, the water grate 3 and the grate plate 32 play a normal role in draining water;

[0075] When there is a lot of debris on the water grate 3 and the grate plate 32, a large amount of water will be retained on the road surface 1. When the accumulated water reaches the position of the overflow port 361, the rainwater enters the interior of the guide pipe 36 through the overflow port 361, and then enters the interior of the water storage tank 35 through the guide pipe 36. The internal water level of the water storage tank 35 gradually rises, and the floating plate 37 rises inside the water storage tank 35. The floating plate 37 allows the guide plate 331 at the upper end of the top rod 33 to pass through the guide hole 322, and the upper end of the top rod 33 is exposed to the water surface. At this time, the cleaning personnel can quickly find the position of the water grate 3. The reflective sticker 332 on the upper end of the top rod 33 facilitates timely discovery at night and reminds the driver that this is the edge of the road surface 1, so as to avoid the wheels hitting the curb 2 due to the inability to see the road surface 1 during driving. When the upper end of the top plate 34 passes through the guide hole 322 and abuts against the top of the grate plate 32, the floating plate 37 continues to rise, and the grate plate 32 can be lifted from the inside of the drain port 31. The drain port 31 can quickly clean the accumulated water and debris on the road surface 1.

[0076] When the water level of the road surface 1 drops below the overflow port 361, the drain hole 351 continues to drain the rainwater in the water tank 35. As the water level gradually drops, the floating plate 37 and the grate plate 32 follow and drop until the grate plate 32 falls onto the drain port 31. At this time, the water grate 3 and the grate plate 32 play a normal role in draining water. When water accumulates on the road surface 1 again, the above steps are repeated to achieve rapid drainage again.

[0077] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
