Description

Technical Field

[0001] The present invention relates to the technical field of sponge city roads, and in particular to a sponge city road system. Background Art

[0002] The sponge city road system is a system that aims at sustainable development and enhances the city's hydrological cycle capacity, flood resistance and ecological functions through the design and construction of road infrastructure.

[0003] At present, sponge city roads rely on the infiltration of rainwater itself to slowly collect rainwater. When encountering special weather, such as heavy rain, the absorption capacity of sponge city roads is limited and they cannot absorb rainwater quickly, causing water accumulation on the roads and affecting traffic. At the same time, when collecting rainwater, they can only collect it first and then filter it centrally, which reduces the efficiency of rainwater collection. Summary of the Invention

[0004] The purpose of the present invention is to provide a sponge city road system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: comprising a road main body, a paving layer connected to the top of the road main body, a filter cavity and a pressurizing chamber provided in the road main body, the top of the filter cavity being connected to a connecting cylinder, the bottom being connected to a cleaning mechanism, the top of the cleaning mechanism being connected to a filter plate, the bottom of the filter cavity being provided with a plurality of water permeable holes, the bottom of the water permeable holes being the same as the pressurizing chamber, and one side of the inner wall being connected to an anti-backflow mechanism, the bottom of the pressurizing chamber being connected to a mounting bracket, the pressurizing chamber being provided with two groups, and a connecting hole being provided on a side close to each other, a drainage hole being provided on one side of the road main body, the top of the mounting bracket being connected to a turbine impeller, the bottom of the road main body being connected to a drive motor, and the output end of the drive motor being connected to the turbine impeller through a magnetic coupling.

[0006] Preferably, the paving layers are all water-permeable layers, and a plurality of absorption holes are opened at the top of the road body corresponding to the paving layers.

[0007] Preferably, a test kit is provided at the top of the road body, a medicine application channel is provided at the bottom of the test kit, one end of the medicine application channel is connected to the pressurizing chamber, and a acid-base detector is connected to one side of the inner wall of the pressurizing chamber.

[0008] Preferably, the cleaning mechanism includes a dust removal rack, guide rails are connected to both sides of the top of the dust removal rack, a cleaning brush roller is slidably provided on the side where the guide rails are close to each other, gears are connected to both ends of the cleaning brush roller, one end of the cleaning brush roller passes through the guide rail and is connected to a waterproof motor, a rack is connected to the top of the dust removal rack, and one side of the gear is engaged with the rack.

[0009] Preferably, the outer ring of the cleaning brush roller is fitted with the filter plate, a fitting groove is provided at the top of the dust removal frame corresponding to the filter plate, and one side of the waterproof motor is slidably connected to the guide rail.

[0010] Preferably, the anti-backflow mechanism includes an outer fixing ring, the top end of the outer fixing ring is connected to a reset spring, the top end of the reset spring is connected to a connecting frame, the bottom end of the connecting frame is connected to a connecting rod, and the bottom end of the connecting rod is connected to a sealing plug.

[0011] Preferably, the sealing plug is arranged in a conical shape, and the outer ring is fitted with the inner ring of the outer fixing ring, and a plurality of water seepage holes are opened at the top of the outer fixing ring.

[0012] Preferably, electromagnetic valves are connected to the inner sides of the connecting hole and the drain hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Rainwater flows into the filtration cavity through the absorption holes on the top of the paving layer and the main body of the road, is filtered by the filter plate, and then flows into the pressurized chamber through the water-permeable holes and the seepage holes on the top of the free outer fixed ring. The drainage holes are connected to the city pipe network, so that the collected and filtered rainwater is discharged to the city's official website. In special weather conditions, the drive motor is started to drive the turbine impeller to rotate, which can speed up the flow of rainwater in the pressurized chamber and accelerate the drainage effect. At the same time, the rotating turbine impeller will form a negative pressure in the pressurized chamber, thereby forming a negative pressure on the top paving layer through the water-permeable holes and the filtration cavity. , increases the suction force, so that the rainwater on the main surface of the road is quickly sucked into the filter cavity. At the same time, the connecting cylinder repeatedly expands and contracts, and the filter plate is driven up and down by the cleaning mechanism to speed up the filtration and water absorption effect. After a large amount of rainwater enters the water-permeable hole, the sealing plug is pushed open and directly discharged from the inner ring of the outer fixed ring to the pressurized chamber. When a pressurized chamber is full, the solenoid valve can be started to drain the rainwater to the adjacent pressurized chamber through the connecting hole, ensuring the treatment effect of excessive rainwater, effectively improving the safety of road traffic in special weather conditions, and improving the efficiency of rainwater treatment;

[0015] 2. The present invention also starts the waterproof motor to drive the cleaning brush roller to rotate, cleans the surface of the filter plate, and drives the gear to rotate. The engagement between the gear and the rack causes the cleaning brush roller to move along the guide rail while rotating, thereby ensuring the cleaning effect of the filter plate surface and the filtering effect of rainwater. At the same time, when collecting rainwater, the internal acid-base detector will detect the pH value of the rainwater. A neutralizer can be added to the test kit and put into the pressurized chamber through the medicine feeding channel. As the turbine impeller rotates, the neutralizer is mixed with rainwater, effectively avoiding the erosion of internal components by rainwater and ensuring the service life.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 The present invention provides a technical solution: it includes a road body 1, a paving layer 2 is connected to the top of the road body 1, a filtering cavity 3 and a pressurizing chamber 9 are provided in the road body 1, the top of the filtering cavity 3 is connected to a connecting cylinder 4, and the bottom is connected to a cleaning mechanism 5, the top of the cleaning mechanism 5 is connected to a filter plate 6, a plurality of water permeable holes 7 are opened at the bottom of the filtering cavity 3, the bottom end of the water permeable holes 7 is the same as the pressurizing chamber 9, and one side of the inner wall is connected to an anti-backflow mechanism 8, the bottom end of the pressurizing chamber 9 is connected to a mounting bracket 10, there are two groups of pressurizing chambers 9, and a connecting hole 11 is opened on the side close to each other, a drainage hole 12 is opened on one side of the road body 1, a turbine impeller 13 is connected to the top of the mounting bracket 10, and a driving motor 14 is connected to the bottom end of the road body 1, and the output end of the driving motor 14 is connected to the turbine impeller 13 through a magnetic coupling.

[0026] The paving layers 2 are all water-permeable layers, and a plurality of absorption holes are provided on the top of the road body 1 corresponding to the paving layer 2 to facilitate the entry of rainwater while ensuring the use effect of the road.

[0027] The anti-backflow mechanism 8 includes an outer fixing ring 81, the top of the outer fixing ring 81 is connected to a return spring 82, the top of the return spring 82 is connected to a connecting frame 83, the bottom of the connecting frame 83 is connected to a connecting rod 84, and the bottom of the connecting rod 84 is connected to a sealing plug 85. When the pressurized chamber 9 is full of collected rainwater, the rainwater overflows upward, and the outer fixing ring 81 is conical and cooperates with the sealing plug 85 to completely seal the pressurized chamber 9. The seepage hole at the bottom of the outer fixing ring 81 can achieve a pressure relief effect to avoid damage caused by excessive water pressure.

[0028] The sealing plug 85 is set in a conical shape, and the outer ring fits with the inner ring of the outer fixed ring 81, which effectively ensures the sealing effect. When 14 drives 13 to rotate, negative pressure can be quickly and effectively formed. There are multiple water seepage holes at the top of the outer fixed ring 81. In the case of light rain, rainwater flows directly into the pressurized chamber 9 through the water seepage holes.

[0029] The inner sides of the connecting hole 11 and the drainage hole 12 are both connected with electromagnetic valves 18, and the corresponding electromagnetic valves 18 can be opened and closed as needed to control the flow direction of the collected rainwater.

[0030] Working principle: When it rains, the rainwater flows into the filter cavity 3 through the absorption holes on the top of the paving layer 2 and the road body 1, is filtered by the filter plate 6, and then flows into the pressurized chamber 9 through the water-permeable holes 7 and the seepage holes on the top of the free outer fixed ring 81. The drainage holes 12 are connected to the city pipe network, so that the collected and filtered rainwater is discharged to the city official website. In special weather conditions, the drive motor 14 is started to drive the turbine impeller 13 to rotate, which can speed up the flow rate of rainwater in the pressurized chamber 9 and accelerate the drainage effect. At the same time, the rotating turbine impeller 13 will form a negative pressure in the pressurized chamber 9, thereby passing through the water-permeable holes 7 and the filter cavity 3 to the top surface. The paving layer 2 forms a negative pressure, which increases the suction force, so that the rainwater on the surface of the road body 1 is quickly sucked into the filter cavity 3. At the same time, the connecting cylinder 4 repeatedly expands and contracts, and the filter plate 6 is driven up and down by the cleaning mechanism 5 to accelerate the filtering and water absorption effect. After a large amount of rainwater enters the water-permeable hole 7, the sealing plug 85 is pushed open and the water is directly discharged from the inner ring of the outer fixing ring 81 to the pressurized chamber 9. When one pressurized chamber 9 is full, the solenoid valve can be started to drain the rainwater to the adjacent pressurized chamber 9 through the connecting hole 11, thereby ensuring the treatment effect of excessive rainwater, effectively improving the safety of road traffic in special weather conditions, and improving the efficiency of rainwater treatment.

A pH detector 17 is provided on one side of the inner wall of the pressurizing chamber 9, and the pH of the collected rainwater can be detected by 17. The pH of rainwater in different regions is different, but it is easy to cause corrosion to the internal equipment.

A limit slider is provided on one side of the waterproof motor 55, and the lower limit slider is slidably connected to the guide rail 52 to ensure that the waterproof motor 55 maintains its own position while moving, and does not rotate itself.

[0036] Working principle: When the invention is in use, the waterproof motor 55 is started to drive the cleaning brush roller 53 to rotate, clean the surface of the filter plate 6, and at the same time drive the gear 54 to rotate. The engagement between the gear 54 and the rack 56 causes the cleaning brush roller 53 to move along the guide rail 52 while rotating, thereby ensuring the cleaning effect of the surface of the filter plate 6 and the filtering effect of rainwater. At the same time, when collecting rainwater, the internal acid-base detector 17 will detect the pH value of the rainwater. A neutralizer can be added to the reagent kit 15 and the neutralizer can be put into the pressurized chamber 9 through the medicine feeding channel 16. As the turbine impeller 13 rotates, the neutralizer is mixed with rainwater, effectively avoiding the erosion of internal components by rainwater and ensuring the service life.
