Please refer to Figures 3, 6 to 9 again. When the present invention is implemented, the ground preparation is first carried out on the floor where the photoelectric permeable pavement is to be constructed, and the permeable unit 20 and the water filling structure 30 are filled according to the overall pavement planning blueprint. The complete layout is carried out over a construction area of the same area as the pavement to be constructed.

The water filling structure 30 can be selected according to the current situation. According to the water filling structure 30 of the preferred embodiment of this case, Fully stocked, the exterior is selectively covered with non-woven fabric 40 according to the geological structure of the site, or is not covered with non-woven fabric, and the non-woven fabric 40 can be either a water-permeable non-woven fabric or a water-impermeable non-woven fabric, and is directly buried in the underground soil according to the predetermined location. In layer A, a water-conducting layer B is also laid on the top, and the permeable unit 20 is completely laid out on the construction area of the pavement to be constructed, so that a water-conducting layer B is lined between the permeable unit 20 and the water flooding structure 30 , the water-conducting layer B can be a gravel layer or a permeable concrete layer or other permeable graded material paving. Then, the fixing member 112 protruding from the bottom of the base 11 of the photovoltaic module 10 is fixed and positioned, preferably embedded in the mouth of the top of the water permeable pipe 21 corresponding to the water permeable unit 20, so that the base 11 can be stably laid on the water permeable unit. 20, and an exposed water permeable pipe 21 is provided in the inner frame of the bare area 113, and the water permeable pipes 21a with a longer tube body in the water permeable unit 20 are arranged and distributed between adjacent bases 11. Furthermore, since the grille top plate 22 is designed at the mouth of the permeable pipe 21, it is manufactured in a thin sheet shape. Therefore, when assembling the base 11 of the photovoltaic module 10, it can be directly connected through the fixing member 112 at the bottom. , that is, it can be easily broken into an open position for embedding and fixing, and then the two ends of the communication tube 13 are respectively embedded in the through holes 114 of the two adjacent bases 11, so that the bases 11 are connected to each other. Finally, concrete slurry is poured to form a permeable pavement.

If a cover or a mesh cover is installed at the mouth of the permeable pipe 21, it can also form a blocking effect. After the concrete slurry 60 is poured, the temporarily blocked cover must be removed to avoid intrusion. Blockage caused by concrete slurry operation.

In order to make the grouting operation of the concrete slurry 60 more convenient, a frame cover 15 can be used to cover the space between the inside of the top edge of the frame 111 of the base 11 of the photovoltaic module 10 and the bare area 113 before the grouting operation, or Another possible way not shown in the figure is to use tape or non-woven fabric to cover the Shield to prevent the area of the base 11 for installing the solar panel 12 from being covered by the concrete slurry 60, and then remove the frame cover 15, tape or non-woven fabric after the concrete slurry 60 solidifies. In addition, when the concrete slurry 60 is poured, the upper ports of each exposed permeable pipe (21, 21a) of the permeable unit 20 are equipped with a grille top plate 22, which can block the concrete slurry at the pipe mouth. Therefore, After the concrete slurry is moderately solidified, you only need to use a high-pressure spray gun to use the high-pressure air or water jets to spray away the mud residue remaining on the grille top plate 22 at the port of each permeable pipe (21, 21a), and then the construction can be completed. A permeable pavement layer C of concrete structure with many drainage holes 26 is formed on the periphery of the base 11 and in the bare area 113. Finally, the solar panels 12 are electrically connected by passing wires through the connecting tubes 13 in each base 11 to complete the installation of the entire photovoltaic permeable pavement.

In this way, when the rainy season comes and heavy rain falls instantly on the surface, the drainage holes 26 formed on the surface between the photovoltaic modules 10 and the appropriate gaps formed between the solar panels 12 and the base 11 can be used to drain the rainwater to the bare surface. Each drainage hole 26 in the empty area 113 quickly drains rainwater to the ground of the aqueduct B through the permeable pipes (21, 21a), which not only achieves flood drainage in a short period of time, but also replenishes groundwater resources. That's it. Gain the function of effectively and quickly draining the ground in a short period of time and replenishing groundwater. And by filling the water storage space inside the structure 30 with water, water can be stored quickly and in large quantities, thereby preventing regional floods in a short period of time. After the rainwater on the ground surface stops seeping, the water can be slowly recovered after a specific period of time. By seeping down to the underground soil layer to replenish groundwater resources, the function of effectively and quickly draining the ground in a short period of time and replenishing groundwater can be obtained, or rainwater can be stored in the water filling structure 30 for subsequent use.

If the weather is sunny, the solar panels 12 arranged in the photovoltaic module 10 can be used to convert the energy of sunlight into electrical energy. At the same time, when the temperature is high and hot on the ground, because the ground contains high moisture content, it can be converted into water. Steam is released to the outside. For the photovoltaic module 10, Not only can the solar panel 12 achieve a moderate cooling effect, thereby extending the service life of the solar panel 12, but it can also increase the photoelectric conversion efficiency, and for the overall environment, it can also perform heat exchange in the environment to avoid the occurrence of the heat island effect. , or slow down the heat island effect. Furthermore, this solar method of generating electricity does not require the use of any fuel, is noise-free, and has no air pollution. It is a clean energy that is friendly to the earth, and the electricity generated can also be used effectively nearby.

When the present invention is implemented, the water filling structure 30 can also be further provided with a water pipe 50 that is penetrated to the inside and connected to the ground, and the exit of the ground end of the water pipe 50 can be connected by one end. The cover 51 is closed, and a water pumping device 52 is provided in the water pipe 50, which can pump out the rainwater stored underground and use it as water for surrounding people's livelihood, environmental watering, automatic cleaning of photovoltaic panels and cooling, and can also be used as a water tank for water decontamination. Water purification and other functions. When needed, the photovoltaic module 10 can be used to provide natural energy to the water pumping equipment, so that the water can be pumped into the structure 30 and pumped up for use, such as watering flowers and trees on the side slopes of the road, etc., for tree planting and maintenance. It is more convenient and can achieve the effect of automation. It can also use the replenished groundwater resources and pump it to the ground for subsequent automatic cleaning of photovoltaic panels, cooling and general use.

Please refer to Figure 11 again. When the permeable unit 20 of the present invention is assembled before the grouting operation, in different embodiments, steel bars 27 or meshes are provided between each permeable pipe (21, 21a). After subsequent concrete pouring, a stronger concrete block layer can be obtained, which can better increase the pressure-bearing gravity of the overall pavement surface.

It can be seen from the above that the structure of the photoelectric underground water filling and storage equipment of the present invention has the following practical advantages:

1. Improve the energy structure, reduce greenhouse gas emissions, reduce air pollution and improve environmental quality through renewable, sustainable and clean green energy power generation.

2. It can reduce surface runoff and reduce the chance of floods. It can also recycle rainwater and replenish groundwater resources. It not only achieves the purpose of water conservation in the base, but also releases water vapor and surface temperature for heat exchange, thereby regulating the overall environment in the environment. Temperature and humidity can effectively reduce or avoid the heat island effect, creating a more efficient sponge city ecological environment.

3. A large underground rainwater storage space can be provided for subsequent use to fully store water and recycle rainwater resources for reuse, while preventing droughts due to water shortage.
