[0008] By adopting the above technical solution, in actual use, when a vehicle passes through the road body, the manhole cover and the mounting plate will vibrate. Such vibration causes the control component to move. When the control component moves along the wall of the mounting cavity, the air pressure in the air intake area and the exhaust area changes, causing the gas to enter the exhaust area and move along the exhaust hole. In this way, the vibration caused by the passage of vehicles enhances the gas exchange in the manhole and the mounting plate, thereby facilitating the gas exchange between the manhole and the outside world, facilitating gas circulation, and reducing the accumulation of harmful gases in the manhole.

[0009] Optionally, the installation cavity extends obliquely in a direction close to the manhole cover, and the control component includes a sliding plate and a sliding spring, the sliding spring is connected to the sliding plate, and when the sliding spring is in a normal state, the sliding plate closes the air inlet hole.

[0010] By adopting the above technical solution, a sliding plate and a sliding spring are set, and the movement of the sliding plate is used to affect the movement of gas in the intake area and the exhaust area, thereby facilitating gas exchange. By setting the installation cavity to extend obliquely in the direction close to the manhole cover, the vibration of the manhole cover and the installation plate is easily transmitted to the sliding plate and the sliding spring, thereby facilitating the movement of the sliding plate.

[0011] Optionally, a control magnetic block 1 is provided on the wall of the installation cavity, and the control magnetic block 1 is located in the exhaust area. The exhaust plate is provided with a control magnetic block 2, and the control magnetic block 2 is located on the side of the exhaust plate close to the control magnetic block 1, and the magnetic force of the control magnetic block 1 and the magnetic force of the control magnetic block 2 attract each other.

[0012] By adopting the above technical solution, control magnet block 1 and control magnet block 2 are set. When the sliding plate moves toward the direction close to control magnet block 1, the magnetic force of mutual attraction between control magnet block 1 and control magnet block 2 increases the moving distance of control magnet block 2 and plays the role of stretching the sliding spring, thereby facilitating the increase of the sliding distance when the sliding plate is reset, thereby amplifying the vibration caused by the passage of the car and the vibration range of the sliding plate, thereby improving the effect of gas exchange.

[0013] Optionally, the mounting plate is provided with an extension pipe, the extension pipe is located on a side of the mounting plate away from the air inlet, the extension pipe is provided with an exhaust channel, and the exhaust channel is connected to the exhaust hole.

[0014] By adopting the above technical solution, the setting of the extension pipe facilitates gas discharge, increases the exhaust height, reduces the inflow of liquid through the exhaust hole, reduces the impact of liquid discharge on gas exchange, and reduces the blockage of the exhaust hole.

[0015] Optionally, a blocking block is provided at the end of the extension tube facing away from the mounting plate, and the blocking block is provided with a blocking cover, which is located at the end of the blocking block close to the mounting plate, and the blocking cover gradually expands in the direction away from the blocking block. An extension hole is provided on the side wall of the extension tube, and the extension hole is located in the blocking cover, and the extension hole is connected to the exhaust channel.

[0016] By adopting the above technical solution, a blocking block is set up to block the liquid flowing in from the connecting hole, and the liquid flow is further guided by the blocking cover, thereby reducing the situation where the liquid enters the exhaust channel from the extension hole and reducing the blockage of the exhaust hole.

It is used for auxiliary support after the manhole cover is damaged. It is used to assist in improving the supporting strength of the mounting plate. It is also convenient to reduce accidental falls during the installation or disassembly of the mounting plate, thereby improving overall safety.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A control member is provided. When a vehicle passes through the road body, the manhole cover and the mounting plate will vibrate. Such vibration causes the control member to move. When the control member moves along the wall of the mounting cavity, the air pressure in the air intake area and the exhaust area changes, causing the gas to enter the exhaust area and move along the exhaust hole. In this way, the vibration caused by the passage of vehicles enhances the gas exchange at the well and the mounting plate, thereby facilitating the gas exchange between the well and the outside, facilitating the gas circulation, and reducing the accumulation of harmful gases in the well;

[0021] 2. A sliding plate and a sliding spring are provided, and the movement of the sliding plate affects the movement of gas in the air intake area and the exhaust area, thereby facilitating gas exchange.

[0022] 3. Control magnet block 1 and control magnet block 2 are set. When the sliding plate moves toward the direction close to control magnet block 1, the magnetic force of mutual attraction between control magnet block 1 and control magnet block 2 increases the moving distance of control magnet block 2 and plays the role of stretching the sliding spring, thereby facilitating the increase of the sliding distance when the sliding plate is reset, thereby amplifying the vibration caused by the passing of the car and the vibration range of the sliding plate, thereby improving the effect of gas exchange.

The mounting plate 5 is provided with a fixing groove 6, and the fixing groove 6 is located at one end of the mounting plate 5 close to the bottom of the mounting groove 2, and the fixing protrusion 4 is embedded in the fixing groove 6. In actual use, an anti-falling net 7 is provided on one side of the well 3 close to the mounting plate 5, and the anti-falling net 7 is fixed by the fixing protrusion 4. The anti-falling net 7 is used to reduce the damage of the well cover and the accidental fall of pedestrians during the maintenance of the inside of the well 3.

[0029] The mounting plate 5 is provided with a connecting hole 8, which passes through the mounting plate 5, and the connecting hole 8 is in a vertical direction, and the connecting hole 8 is for the gas in the well 3 to pass through. A support block 9 is provided at one end of the mounting plate 5 away from the well 3, and a manhole cover is provided on the side of the support block 9 away from the mounting plate 5, and the manhole cover is provided with a ventilation hole 10, which passes through the manhole cover, and the ventilation hole 10 is in a vertical direction. When the manhole cover hits the support block 9, an exhaust cavity 11 is formed between the manhole cover and the mounting plate 5, and the connecting hole 8 connects the well 3 with the exhaust cavity 11, and the ventilation hole 10 connects the exhaust cavity 11 with the outside world. Through the cooperation of the ventilation hole 10 and the connecting hole 8, the gas circulation between the well 3 and the outside world is carried out, and the accumulation of harmful gases in the well is reduced. Secondly, the auxiliary support of the manhole cover by the mounting plate 5 improves the overall safety, and the mounting plate 5 can also be used for secondary protection after the manhole cover is damaged.

[0030] The mounting plate 5 is provided with a mounting cavity 12, and the mounting cavity 12 extends obliquely in the direction close to the manhole cover. The wall of the mounting cavity 12 is provided with a control member 13, and the control member 13 slides on the wall of the mounting cavity 12. The control member 13 divides the mounting cavity 12 into an exhaust area 14 and an intake area 15, and the exhaust area 14 is located above the intake area 15. In the present application, the control member 13 includes a sliding plate 132 and a sliding spring 131, and the sliding spring 131 is located in the intake area 15 and connected to the wall of the mounting cavity 12. The sliding spring 131 is connected to the sliding plate 132 at one end away from the connection between itself and the wall of the mounting cavity 12, and the sliding plate 132 slides on the wall of the mounting cavity 12, and the sliding direction of the sliding plate 132 is the inclination direction of the mounting cavity 12. The exhaust plate is provided with a control magnetic block 17, and the control magnetic block 17 is located at one end of the exhaust plate away from the sliding spring 131.

[0031] The mounting plate 5 is provided with an air inlet 18 and an air outlet 19. The air inlet 18 is located at the end of the mounting plate 5 away from the support block 9. The air inlet 18 is used to connect to the air inlet area 15. The air outlet 19 is located at the end of the mounting plate 5 close to the manhole cover. The air outlet 19 connects to the air outlet area 14. When the sliding spring 131 is in a normal state, the sliding plate 132 closes the air inlet 18. When the mounting plate 5 vibrates, the sliding plate 132 moves along the wall of the mounting cavity 12 and repeatedly pushes the gas in the air outlet area 14 to move along the air outlet 19. The wall of the mounting cavity 12 is provided with a control magnetic block 16. The control magnetic block 16 is located in the air outlet area 14.

[0033] The implementation principle of a sponge city drainage structure in an embodiment of the present application is as follows: in actual use, when a vehicle travels on the road body 1, the vibration of the vehicle causes the manhole cover and the mounting plate 5 to vibrate. At this time, the vibration is transmitted to the mounting cavity 12 and causes the sliding spring 131 to vibrate, and causes the sliding plate 132 to move along the extension direction of the mounting cavity 12. The magnetic force of the control magnetic block 16 and the control magnetic block 2 17 increases the sliding direction of the sliding plate 132, so that the sliding plate 132 compresses the range of the exhaust area 14 back and forth, and causes the gas entering from the air inlet 18 to move toward the exhaust hole 19, thereby improving the gas exchange efficiency between the well 3 and the outside world.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
