Among them, the urban drainage system is related to the urban environment and the normal travel of residents. When encountering heavy rain or in the rainy season, a more complete drainage system is needed, otherwise it is easy to cause urban waterlogging and hinder residents' travel.

[0003] The existing urban drainage system uses sewer drainage, and on sidewalks and other roads, a combination of sand, gravel and bricks is used to allow rainwater to penetrate directly into the earth, thereby assisting urban drainage and avoiding waterlogging on the sidewalks.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0021] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0022] As one of the specific embodiments of the present invention, as shown in the figure, a permeable pavement includes a permeable top layer 1 and a lower shell 5, a containing cavity 3 is formed between the permeable top layer 1 and the lower shell 5, the lower shell 5 has good waterproof performance, an upper drain port 15 is provided at the bottom of the lower shell 5, a lower drain port 16 is connected below the upper drain port 15, the lower drain port 16 leads to the land, the cross-sectional area of ​​the lower drain port 16 is smaller than the cross-sectional area of ​​the upper drain port 15, an installation cavity 20 is provided below the upper drain port 15, an installation shaft 21 is provided inside the installation cavity 20, a torsion spring 22 is sleeved on the installation shaft 21, and the installation shaft 20 is provided with a torsion spring 22. The top of the housing 5 extends upward and is connected with a rotary valve 17, on which a water outlet 19 is provided. The rotary valve 17 has a first state and a second state. In the first state, the water outlet 19 is misaligned with the lower drain port 16. In the second state, the water outlet 19 is communicated with the lower drain port 16. A pull rope 8 is connected to the circumference of the rotary valve 17. A pull rope channel 9 is provided on the lower housing 5. The pull rope 8 extends from the pull rope channel 9 and extends upward from the pull rope channel 9. The extended portion of the pull rope 8 is fixedly connected with a floating block 7. A vertically installed track column 6 is provided in the accommodating chamber 3. The floating block 7 is installed on the track column 6 in a manner that it can move up and down. During use, in some northern cities of my country, the weather is relatively dry. When it rains, rainwater penetrates from the permeable top layer 1 into the accommodating chamber 3, and the accommodating chamber 3 retains the rainwater. When the rain stops and the weather turns clear, the rainwater evaporates from the accommodating chamber 3 and enters the air from the permeable top layer 1, which plays a role in increasing humidity. During the raining process, if there is a lot of rain, the water level of the rainwater in the accommodating chamber 3 continues to rise, and the floating block 7 rises with the rise of the water level. The floating block 7 pulls the pull rope 8, and the pull rope 8 pulls the rotary valve 17 to rotate, so that the rotary valve 17 switches from the first state to the second state, and the rainwater flows from the upper drainage port 15 and flows through the water outlet 19, and is discharged from the lower drainage port 16 to the ground, maintaining the water level in the accommodating chamber 3. The accommodating chamber 3 can increase the water capacity of the urban drainage system, and at the same time, the rainwater in the accommodating chamber 3 can provide the moisture required to increase the air humidity in the clear weather after the precipitation, thereby reducing the dryness of the city.

[0023] In some optional specific embodiments, an inner shell 10 is provided at the bottom of the accommodating chamber 3, a motor 11 is installed above the inner shell 10, the motor 11 is connected to a rotating shaft 12, the rotating shaft 12 extends downward to the inside of the inner shell 10, a connecting rod 13 is connected to the side of the rotating shaft 12, an annular sleeve 14 is installed at one end of the connecting rod 13 away from the rotating shaft 12, a pull rope 8 passes through the annular sleeve 14 and extends upward through the inner shell 10, a humidity switch 2 is provided on the water-permeable top layer 1, and the humidity switch 2 is electrically connected to the motor 11. When the humidity in the air is low, the rainwater in the accommodating chamber 3 needs to be discharged at this time, the humidity switch 2 controls the motor 11 to start, the rotating shaft 12 rotates, the connecting rod 13 rotates, and the pull rope 8 is pulled, so that the rotary valve 17 rotates open, and the rainwater flows downward.

[0024] In some optional specific embodiments, the lower drain port 16, the upper drain port 15 and the rotary valve 17 each have two groups, and the two groups of the lower drain port 16, the upper drain port 15 and the rotary valve 17 are arranged on both sides of the rotating shaft 12, and the connecting rod 13 has two groups, which are respectively arranged on both sides of the rotating shaft 12. When the motor 11 is started, the two groups of rotary valves 17 can be opened at the same time.

[0025] In some optional specific embodiments, a connecting channel 4 is provided on the side wall of the lower shell 5, and the connecting channel 4 connects the containing chambers 3 of two adjacent permeable pavements. When there is more rainwater in the containing chamber 3 of one of the permeable pavements, the rainwater will flow through the connecting channel 4 to the containing chamber 3 of the adjacent permeable pavement, thereby increasing the water capacity.

[0026] In some optional specific embodiments, a receiving groove 18 is provided in the middle of the circumference of the rotary valve 17 . The receiving groove 18 is provided along the circumference of the rotary valve 17 , and is annular. The pull rope 8 is wound around the receiving groove 18 .

[0027] In some optional specific embodiments, the outer periphery of the rotary valve 17 is wrapped with a waterproof layer, and the waterproof layer increases the sealing performance of the rotary valve 17 .

[0028] In some optional specific embodiments, the pull rope 8 is made of rubber, and the diameter of the pull rope 8 is adapted to the cross-sectional diameter of the pull rope channel 9, thereby reducing the occurrence of rainwater flowing out of the pull rope channel 9.

[0029] The working principle of the present invention: when in use, in some northern cities in my country, the weather is relatively dry. When it rains, rainwater penetrates into the accommodating chamber 3 from the permeable top layer 1, and the accommodating chamber 3 retains the rainwater. When the rain stops and the weather clears up, the rainwater evaporates from the accommodating chamber 3 and enters the air from the permeable top layer 1, which increases the humidity. During the rainfall process, if there is a lot of rain, the water level in the accommodating chamber 3 continues to rise, and the floating block 7 rises with the rise of the water level. The floating block 7 pulls the pull rope 8, and the pull rope 8 pulls the rotary valve 17 to rotate, so that the rotary valve 17 switches from the first state to the second state, and the rainwater flows from the upper drain port 15 and flows through the outlet 19, and is discharged from the lower drain port 16 to the ground, maintaining the water level in the accommodating chamber 3.

[0030] The accommodating chamber 3 can increase the water capacity of the urban drainage system. Meanwhile, the rainwater in the accommodating chamber 3 can provide the moisture required to increase the air humidity in clear weather after precipitation, thereby reducing the dryness and temperature of the city.
