[0002] In recent years, the construction of mountain photovoltaics in my country has been accelerating. At present, the drainage design of mountain photovoltaics often considers the use of the method of following the slope for drainage. This design method has great problems. When it rains, rainwater constantly washes the soil, which is very likely to cause soil erosion. On the one hand, the continuous loss of soil and water can easily lead to the instability of the slope; on the other hand, with the continuous loss of soil and water, the height of the photovoltaic bracket foundation leaking out of the ground continues to increase, seriously affecting the bearing capacity of the photovoltaic bracket foundation and endangering the safety of the photovoltaic bracket system. The traditional method of preventing soil and water loss on the slope has a high cost and poor soil and water conservation effect. Therefore, a convenient, efficient and low-cost mountain photovoltaic drainage system that prevents soil and water loss is urgently needed. Utility Model Content
