Technical Field

Background
In recent years, with the continuous acceleration of the urbanization process, the area of the urban hard paving structure is increased day by day, so that waterlogging is easily caused in rainy seasons, and the heat island effect is easily caused in summer. To the easy waterlogging problem in rainy season, permeable pavement makes the rainwater can see through this structure and get into the road surface inside as a new road surface structure through adopting great void structure, and this structure can reduce the surface runoff and delay the biggest peak value epoch. However, if the rainwater can not be removed in time after entering the interior of the road surface, the strength of the internal structure is easily weakened, and the bearing capacity of the whole structure is greatly influenced. Further research is needed regarding the disposal of rainwater internally. Furthermore, there are three ways to mitigate the heat island effect that are commonly employed: (1) the heat absorbed by the road surface is reduced; (2) increase the thermal capacity of the road surface; (3) the heat absorbed by the pavement is transferred to the subgrade or near-ground area. In general, the way of radiating heat through the coating and transferring the heat to other areas is one-sided, and the influence on the pavement cooling effect in a long-term high-temperature environment is small. The temperature of the road surface can be reduced fundamentally only by improving the specific heat capacity of the road surface and increasing the property that the temperature is not easy to change after the road surface absorbs heat. To further reduce the temperature of the near-surface air, the effect of increasing the specific heat capacity of the road surface alone is insignificant, especially in areas higher from the road surface, where the effect of the road surface is essentially negligible. Thus, the near-surface temperature can be reduced by increasing the specific heat capacity of the structure in the near-surface region, thereby mitigating the urban heat island effect.

In addition, the water which absorbs enough heat can be conveyed into the heat converter through the water outlet pipeline, then the heat is stored through the heat storage unit, and the stored heat can be used for snow melting and ice melting in winter and is converted into electric energy to supply power for the sensor and the like.
Specifically, the device comprises a street lamp 13, a layered water storage tank 14, a water supply system, a drainage system, an energy storage system, an underground water storage chamber and a permeable pavement structure.
The street lamp 13 is an existing street lamp structure in a city, and a lamp post of the street lamp can provide a support structure for the layered water storage tank 14.
The layered water storage tank 14 is composed of a box structure with an opening on the top surface and made of a material which is impermeable to water and has better weather resistance. In order to ensure that each water tank can effectively store water, each side length of the water storage tank in the horizontal direction of the next layer of water storage tank is larger than the side length of the water storage tank in the previous layer of water storage tank. When the water storage tank of the previous layer is full of water, the water can overflow to fill the water storage tank of the next layer, and when all the water storage tanks are full, the control system controls the water pump 6 to stop working. In addition, in order to ensure the absorption capacity of the solar heat, the size of each layer is enough according to the actual condition.
