Solar power generating equipment

Abstract

The invention relates to solar power generating equipment which comprises a driving device, a power device, a generator and a storage battery, wherein the driving device comprises a heat exchanger, an energy accumulator and a driving cylinder which are connected through hydraulic tubes and change valves to form a closed-loop driving system, and the system is filled with operating fluid; the power device comprises a power cylinder and a hydraulic motor which are connected through a circulating tube to form a closed-loop power system, and the system is filled with the operating fluid; and a piston in the driving cylinder and a piston in the power cylinder are connected into a whole through a piston rod. In the daytime, the operating fluid in the driving system absorbs solar heat, expands continuously to produce pressure and drives the generator to operate and generate electricity through the driving cylinder, the power cylinder, the hydraulic motor and a transmission device. At night, the operating fluid in the driving system contracts continuously due to temperature reduction to produce negative pressure and drives the generator to rotate reversely and generate electricity through the driving cylinder, the power cylinder, the hydraulic motor and the transmission device. In the invention, conventional mechanical devices can be used for converting solar energy into electric energy by using the natural characteristics of diurnal temperature change and fluid expansion with heat and contraction with cold. The solar power generating equipment not only can be used independently, but also can be used for forming a large-scale generating system. While in use, only simple regular maintenance is needed without any cost. The invention provides a new approach for effectively utilizing solar energy and can produce great economical benefits and social benefits in modern society where low-carbon lifestyle is proposed and energy resource crisis becomes more and more serious.

Description

1. Technical Field [0001] The invention relates to power generation equipment, in particular to a solar power generation equipment. 2. Background technology [0002] Energy is the material basis for human existence. With economic development and social progress, human demand for energy is increasing. For a long time, people's unrestrained exploitation and use of mineral energy has not only caused a sharp decrease in its reserves, but also brought global environmental pollution and ecological damage, posing a threat to human survival and development, which forced people to develop as soon as possible And the use of new alternative energy sources. [0003] The sun is emitting energy to the earth at all times. As long as it can be received and utilized, there is no need to worry about its source; the use of solar energy does not require transportation, costs, and does not harm the environment. Therefore, countries all over the world attach great importance to the development and deve...

Problems solved by technology

However, there are some defects in the existing power generation methods: thermal power generation will pollute the environment, hydropower generation is harmful to the natural ecology, nuclear power generation has the risk of leakage, and wind power generation has high costs due to scattered and interconnected units.

However, these two photovoltaic cells are restricted by the physical properties of the materials, and the photoelectric conversion efficiency is low. What's more, the pollution and damage of polysilicon itself to the environment can hardly offset the benefits of its power generation, which will become a constraint on solar power generation. The most critical factor

[0006] To sum up, due to the immature technology of the existing solar power generation method, the investment is too high, and it cannot compete with the conventional power generation method in terms of economy, and it is very difficult to popularize and apply it.
