The water collecting well 1 is provided with a filtering assembly 2, which comprises a mesh plate 21 and a filtering cloth 22. The mesh plate 21 is arranged in the water collecting well 1 and can move along the axis direction of the water collecting well 1. The filtering cloth 22 is fixed to the top of the mesh plate 21 and can filter impurities and sludge in the rainwater, thereby improving the quality of the rainwater and preventing the rainwater from affecting the water quality of the lake.

The lifting assembly and the spraying assembly 3 are provided with a water inlet assembly 7.

[0047] In high-temperature weather, the spraying assembly 3 can be lifted by the lifting assembly. At the same time, the water inlet assembly 7 delivers the rainwater in the water storage tank 11 to the spraying assembly 3, and finally the spraying assembly 3 can spray the rainwater onto the road surface to reduce the temperature of the road surface, so that the tire temperature is not easily increased due to the high temperature of the road surface during vehicle driving, thereby protecting the personal safety of the driver from dangerous situations; and the road surface is sprayed with rainwater, so that it is not necessary to use a water truck to spray the road surface, thereby not only improving the utilization rate of rainwater, but also achieving the effect of saving water resources.

[0048] After spraying is completed, the spraying assembly 3 can be lowered again by the lifting assembly, thereby preventing the vehicle from being affected.

[0049] Referring to Figure 4 The spraying assembly 3 comprises a spraying pipe 31, a spraying plate 32, a warning belt 33, and a spray head 34. The spraying plate 32 is provided with a water inlet cavity 321 inside, and a plurality of arrangement holes 322 that are in communication with the water inlet cavity 321 are arranged on the side wall of the spraying plate 32 along the circumferential direction. The plurality of arrangement holes 322 are uniformly arranged along the circumferential direction, and the spray head 34 is fixedly installed in the arrangement hole 322 and used for spraying rainwater on the road surface. One end of the spraying pipe 31 penetrates through the filtering cloth 22 and is connected with the mesh plate 21, and the other end penetrates through the well cover 16 and is fixed with the spraying plate 32 and in communication with the water inlet cavity 321.

[0050] Referring to 3 and Figure 4, the lifting assembly is arranged between the water storage tank 11 and the spray pipe 31, and the water inlet assembly 7 is arranged between the lifting assembly and the spray pipe 31, so that the spray pipe 31 can be lifted by the lifting assembly in high-temperature weather; at the same time, the water inlet assembly 7 can deliver the rainwater in the water storage tank 11 to the spray pipe 31, the rainwater enters the water inlet cavity 321 from the spray pipe 31, and finally the rainwater is sprayed out of the spray head 34, so as to spray the rainwater on the road surface, thereby reducing the temperature of the road surface.

[0051] Referring to Figure 4 , the warning strip 33 is attached to the side wall of the spray plate 32 and is located between the adjacent arrangement holes 322, and the warning strip 33 is black and yellow in the embodiment of the application, and the black and yellow are arranged alternately, so that the warning strip 33 can warn the vehicles driving on the road when the spray pipe 31 sprays the rainwater on the road surface, thereby avoiding traffic accidents.

[0052] Referring to Figure 4 , further, the top wall of the well lid 16 is provided with a placement hole 161, and the spray plate 32 is placed in the placement hole 161, so that the spray plate 32 is not easy to be higher than the well lid 16, thereby avoiding affecting the driving of the vehicle.

[0053] Referring to Figure 3 and Figure 5 , the water inlet assembly 7 comprises a water inlet pipe 71, a hose 72 and a sleeve ring 73, the top wall of the net plate 21 is provided with a mounting hole 211, and one end of the spray pipe 31 away from the spray plate 32 is fixedly installed in the mounting hole 211. One end of the water inlet pipe 71 is connected with the lifting assembly, the other end penetrates into the water collecting well 1 and is located below the net plate 21, one end of the hose 72 is in communication with the water inlet pipe 71 located in the water collecting well 1, the other end extends into the mounting hole 211 and is in communication with the spray pipe 31, and the hose 72 is long enough in the embodiment of the application, so as to meet the rising height of the net plate 21.

[0054] Referring to Figure 5 , the sleeve ring 73 is rotatably installed in the mounting hole 211, and the sleeve ring 73 is fixedly sleeved on one end of the hose 72 located in the mounting hole 211, so that the hose 72 is not easy to rotate with the net plate 21 when the net plate 21 rotates, thereby avoiding affecting the rotation of the net plate 21. In the embodiment of the application, the two hoses 72 are combined and communicated to share a single sleeve ring 73.

[0055] Referring to Figure 3 , the lifting assembly comprises an impact part 4, a driving part 5 and a connecting part 6.

[0056] Referring to Figure 3, the impact part 4 comprises a high-pressure submersible pump 41, a thin tube 42 and a thick tube 43, the high-pressure submersible pump 41 is installed in the water storage tank 11, the high-pressure submersible pump 41 can provide a larger water pressure, so that the rainwater impacts the driving part 5 more violently. The thick tube 43 is fixed to the inner wall of the water collecting well 1, one end of the thin tube 42 is connected with the high-pressure submersible pump 41, the other end penetrates into the water collecting well 1 and extends into the thick tube 43, and the thin tube 42 and the thick tube 43 are not located on the same axis, so as to impact one side of the driving part 5.

[0057] Referring to Figure 3 , the driving part 5 comprises a vane plate 51 and a rotating shaft 52, the rotating shaft 52 is rotatably installed in the thick tube 43 and is vertically arranged. One end of the rotating shaft 52 is fixed with the vane plate 51, and the other end penetrates out of the thick tube 43.

[0058] Referring to Figure 3 , the connecting part 6 comprises a sleeve 61, a driving gear 62 and a driven gear 63, the sleeve 61 is rotatably installed on the bottom wall of the well cover 16, and the sleeve 61 is threadedly sleeved on the spray pipe 31. The driving gear 62 is coaxially sleeved on the end of the rotating shaft 52 away from the vane plate 51, the driven gear 63 is coaxially sleeved on the sleeve 61, and the driven gear 63 is engaged with the driving gear 62, and the diameter of the driving gear 62 is greater than the diameter of the driven gear 63 in the embodiment of the application.

[0059] When it is needed to rise the spray pipe 31, one of the high-pressure submersible pumps 41 is started to deliver the rainwater in the water storage tank 11 into the thin tube 42, and then into the thick tube 43; when the rainwater is sprayed out of the thin tube 42, the rainwater will hit the vane plate 51, so as to drive the rotating shaft 52 corresponding to the high-pressure submersible pump 41 to rotate clockwise; the rotation of the rotating shaft 52 will in turn drive the rotation of the driving gear 62, the driven gear 63 and the sleeve 61, at this time, the limiting assembly 8 can limit the vane plate 21, so that the vane plate 21 does not follow the rotation, so that the spray pipe 31 rises in the vertical direction, so that the rainwater can be sprayed on the road surface;

[0060] After the spray pipe 31 can no longer rise, the limiting assembly 8 no longer has the limiting effect on the vane plate 21, therefore, the spray pipe 31 can rotate at high speed, so that through the centrifugal force generated when the spray pipe 31 rotates, the sprayed rainwater can be thrown farther, so as to increase the spraying area;

[0061] After the spraying is completed, the previously started high-pressure submersible pump 41 is closed, and another high-pressure submersible pump 41 is started to drive the rotating shaft 52 corresponding to the high-pressure submersible pump 41 to rotate counterclockwise; at this time, the limiting assembly 8 can limit the vane plate 21, so that the vane plate 21 does not follow the rotation, so that the spray pipe 31 descends in the vertical direction, so as to achieve the effect of being retracted, so as not to affect the driving of the vehicle.

[0062] Referring to Figure 6 , the limiting assembly 8 comprises a limiting part 81 and a repulsion part 82.

[0063] Referring to Figure 6 , the limiting part 81 comprises a limiting rod 811 and a limiting spring 812, and the inner wall of the water collecting well 1 is provided with a limiting groove 19 along the axial direction, and the side wall of the mesh plate 21 is provided with a containing hole 213. One end of the limiting rod 811 is arranged in the accommodating hole 322, and the other end is arranged in the limiting groove 19, and the limiting rod 811 can limit the mesh plate 21. One end of the limiting spring 812 is fixed with the limiting rod 811, and the other end is fixed with the hole bottom of the containing hole 213, and the limiting spring 812 is used for pushing the limiting rod 811 into the limiting groove 19.

[0064] Referring to Figure 7 , Figure 8 and Figure 9 , the side wall of the end of the limiting rod 811 away from the limiting spring 812 is provided with a guide surface 8111, and the directions of the two guide surfaces 8111 are opposite, and the direction of one of the guide surfaces 8111 is opposite to the clockwise rotation direction of the rotating shaft 52 corresponding to the high-pressure submersible pump 41. The guide surface 8111 is inclinedly arranged, and the end of the guide surface 8111 close to the limiting spring 812 is limited downward. When the limiting rod 811 is not moved to the top end of the limiting groove 19, the end of the guide surface 8111 close to the limiting spring 812 is higher than the opening of the containing hole 213; when the limiting rod 811 is moved to the top end of the limiting groove 19, the end of the guide surface 8111 close to the limiting spring 812 is lower than the opening in the containing hole 213.

[0065] Referring to Figure 6 , the repulsion part 82 comprises a magnetic block one 821 and a magnetic block two 822, and the groove bottom at the top end of the limiting groove 19 is provided with a containing hole 191, and the magnetic block two 822 is fixed in the containing hole 191. The end wall of the end of the limiting rod 811 away from the limiting spring 812 is fixed with the magnetic block one 821, and the magnetic block one 821 and the magnetic block two 822 are repulsive to each other. When the spray pipe 31 is driven to rise, because the end of the guide surface 8111 close to the limiting spring 812 is higher than the opening of the containing hole 213, the limiting rod 811 has a limiting effect on the mesh plate 21, so that the mesh plate 21 does not follow the rotation, so that the spray pipe 31 rises along the vertical direction;

[0066] When the limiting rod 811 moves to the top end of the limiting groove 19, the magnetic block one 821 and the magnetic block two 822 repel each other, so that the limiting rod 811 is pushed into the containing hole 213, but not completely pushed into the containing hole 213 and leaves a part in the limiting groove 19, so that the guide surface 8111 is lower than the opening of the containing hole 213 at one end of the limiting spring 812, so that the limiting rod 811 no longer has a limiting effect on the mesh plate 21. Whenever the mesh plate 21 rotates, the limiting rod 811 will be pressed back into the containing hole 213 through the guide surface 8111, so that the spray pipe 31 can rotate;

[0067] After the spraying is completed, when the other high-pressure submersible pump 41 drives the rotating shaft 52 corresponding to the high-pressure submersible pump 41 to rotate counterclockwise, the limiting rod 811 will not be pressed into the containing hole 213 due to the setting of the guide surface 8111. Once the limiting rod 811 rotates to the limiting groove 19, the limiting rod 811 will be automatically inserted into the limiting groove 19 by the elastic force of the limiting spring 812, and then the mesh plate 21 cannot rotate any more, so that the spray pipe 31 can descend in the vertical direction.

[0068] Referring to Figure 3 Further, the top end of the water collecting well 1 is fixedly sleeved on the garbage can 9, and the thin pipe 42 penetrates through the garbage can 9. The top of the garbage can 9 is provided with a cover body, so as to facilitate the treatment of the garbage in the garbage can 9. A plurality of discharge holes 17 are formed in the inner wall of the water collecting well 1 and penetrate through in the circumferential direction. In the embodiment of the application, there are four discharge holes 17. The side of the garbage can 9 close to the water collecting well 1 is provided with a feeding hole 91 which penetrates through and corresponds to and communicates with the discharge hole 17.

[0069] After the limiting rod 811 moves to the top end of the limiting groove 19, the top wall of the filter cloth 22 is flush with the inner bottom wall of the discharge hole 17. At this time, the mesh plate 21 has a certain centrifugal force due to rotation, so as to be able to throw the impurities and sludge on the filter cloth 22 to the outer edge of the filter cloth 22. Then, whenever passing through the discharge hole 17 and the feeding hole 91, the impurities and sludge will be thrown into the garbage can 9 for storage, so as to be able to complete the cleaning of the impurities and sludge on the top of the filter cloth 22, so as to improve the subsequent filtering quality of the rainwater.

[0070] Referring to Figure 3 The discharge hole 17 is provided with a blocking assembly 10. The blocking assembly 10 comprises a blocking plate 101 and a pushing rod 102. The inner top wall of the discharge hole 17 is provided with a containing groove 171. The inner wall of the water collecting well 1 is provided with a giving-up groove 18 which communicates with the containing groove 171 and penetrates through in the axial direction. One end of the blocking plate 101 is arranged in the discharge hole 17, and the other end is arranged in the containing groove 171. The blocking plate 101 can close the discharge hole 17, so that the rainwater flowing into the water collecting well 1 is not easy to flow into the garbage can 9.

[0071] Referring to Figure 3One end of the pushing rod 102 is fixed to the side of the blocking plate 101 away from the garbage can 9, and the other end is arranged in the positioning slot 18. In the embodiment of the application, the pushing rod 102 is in the shape of "L". When the limiting rod 811 is about to move to the top of the limiting slot 19, the mesh plate 21 abuts against the pushing rod 102, and then when the mesh plate 21 rises again, the mesh plate 21 will push the pushing rod 102 to drive the blocking plate 101 to rise, thereby slowly opening the discharge hole 17; until the limiting rod 811 moves to the top of the limiting slot 19, the blocking plate 101 completely opens the discharge hole 17, thereby facilitating the impurities and sludge to be thrown into the garbage can 9.

[0072] The working principle of the sponge city infiltration and drainage structure of the application in use is as follows: when it is necessary to lift the spray pipe 31, one of the high-pressure submersible pumps 41 is started to deliver the rainwater in the water storage tank 11 into the fine pipe 42, and then into the thick pipe 43; when the rainwater is sprayed out of the fine pipe 42, the rainwater will hit the vane plate 51, thereby driving the rotating shaft 52 corresponding to the high-pressure submersible pump 41 to rotate clockwise; the rotation of the rotating shaft 52 will in turn drive the rotation of the driving gear 62, the driven gear 63 and the sleeve 61; at this time, the limiting assembly 8 can limit the mesh plate 21, so that the mesh plate 21 does not follow the rotation, and thus the spray pipe 31 will rise in the vertical direction, so that the rainwater can be sprayed on the road surface.

[0073] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
