[0002] At present, photovoltaic power stations are usually built in the goaf of coal mines to make full use of the land, and grass planting is carried out at the photovoltaic power stations to supply animal husbandry, so as to develop the ecological value of photovoltaic power stations. However, due to the damage caused by coal mining and the construction of photovoltaic power stations to the geology, the geology of the goaf of coal mines usually causes geological degradation such as soil desertification, and the growth environment of vegetation is poor.

[0003] In order to ensure the normal growth of vegetation, the photovoltaic area will be irrigated. The existing ecological irrigation of photovoltaic areas still adopts the method of large-scale agricultural irrigation, because photovoltaic power stations are usually built in areas with strong light.

[0034] By applying the technical solution of the present invention, the support frame 220 can lift the photovoltaic panel 210, so that a shade area is formed under the photovoltaic panel 210. Because the photovoltaic panel 210 needs to face the optimal light direction during design and construction, the shade area under the photovoltaic panel 210 will be in a long shade state, and the light in the shade area will be longer than other areas. In this application, a spray pipe 310 is arranged to pass through the support frame 220, so that the spray pipe 310 sprays irrigation into the shade area. The vegetation and soil growing in the shade area have stronger water retention capacity, less water evaporation during and after irrigation, and reduced non-uniform settlement of the ground, thereby ensuring the stability of the photovoltaic power generation device 200. After entering the soil layer, water can diffuse to the soil layer in the non-shaded area, thereby reducing soil and water loss, which is beneficial to vegetation growth. After natural replacement, an ecological cumulative effect is formed, soil fertility is improved, and a virtuous cycle is formed during irrigation to ensure irrigation effect.

[0035] Specifically, a plurality of photovoltaic power generation devices 200 are provided, and the plurality of photovoltaic power generation devices 200 are arranged at intervals along the first direction.

The present application utilizes the water stored in the water storage device 100 in the irrigation system, so that the water is cooled and flows through the photovoltaic panel 210 for heat exchange, thereby reducing the stability of the body and the bottom plate of the photovoltaic panel 210, and effectively reducing the temperature of the photovoltaic panel 210.

[0047] like Figure 6 and Figure 7As shown, the cooling assembly 520 includes multiple groups of heat exchange tubes 521 and fans 522.

Specifically, a one-way valve may be provided on the manifold 640 , and the manifold 640 is connected to the upstream of the first pump body 101 to ensure the correct circulation of water.
