Against the backdrop of increasing global energy shortage and deteriorating environment, solar energy and wind energy, as sustainable and clean energy sources, have attracted great attention from all quarters.

In recent years, my country's photovoltaic industry has developed rapidly driven by national large-scale engineering projects, promotion plans and international cooperation projects. As the direction of energy development in the future, solar energy and wind energy, as new energy street lights, have the characteristics of not being affected by power supply, not consuming conventional electric energy, as long as there is sufficient sunlight, etc. Known as a green product, the operation and maintenance costs are low, and the operation of the entire system is automatically controlled without human intervention, and there is almost no maintenance cost. However, most of the existing solar power generation is flat and the installation angle is fixed, so the solar panels cannot fully absorb and convert sunlight, the power generation cannot be guaranteed, and it is difficult to use it continuously. The power generation device cannot use rainwater to generate electricity. Therefore, it is necessary to adopt a new technical solution to solve the above problems.

Regarding the technical scheme of new energy power generation, relevant technical schemes have been disclosed, such as Chinese patent number: ZL201420431568.4, authorized announcement date: February 4, 2015, and the name of the invention is: a solar street lamp.

A rainwater power generation device is installed on the vertical section of the light pole, and an electric energy storage device is installed on one side of the light pole. . The patent scheme sets the solar panel into a trumpet-shaped structure, so that with the rotation of the sun, the solar panel has a large light-receiving area, and at the same time, it can also collect rainwater from the rain into the light pole to impact the rainwater power generation device, and use the gravity of the rainwater Potential energy to generate electricity. Although this solution can maintain the power generation state when the sun's irradiation orientation changes, the area that can receive the sun's irradiation is limited because the power generation devices are distributed in a cone shape.

Another example is the Chinese patent application number: 201320158483.9, application date: April 2, 2014, and the name of the invention is: an energy self-supply device, including a solar panel body, a windmill, a utility pole, and a street lamp. The windmill is arranged on the utility pole and electrically connected with the street lamp; the windmill is arranged on the solar panel body and electrically connected with the solar panel body, which belongs to the technical field of energy application. Although this patented solution can utilize both wind energy and solar energy, the area of solar panel power generation is small, wind power generation is greatly affected by wind direction, and the power generation efficiency needs to be improved.
