Sand power electricity generation device

Abstract

The invention provides a sand power electricity generation device. The sand power electricity generation device comprises a sand box used for collecting sand materials, an electric generator impeller used for receiving the sand materials and a sand tank used for storage of the sand materials, wherein a conveying device used for conveying the sand materials in the sand tank to the sand box is connected between the sand tank and the sand box, a discharge port is formed in the bottom of the sand box, a valve is arranged on the discharge port, and the conveying device is driven by a photovoltaic electric generator. According to the device, the sand materials in the sand tank is conveyed to the sand box to be stored through photovoltaic power generation in the daytime, and at night or in rainy days, the valve on the discharge port is opened, the sand materials in the sand box fall to strike the impeller, then, the impeller rotates to drive the electric generator to generate electricity. The electric generation principle of the device is converting potential energy into electric energy, no chemical changes are caused, nor are harmful substances discharged, and the influences on the environment are less. In addition, the conveying device is driven through electricity generated by the photovoltaic electric generator, no other energy needs to be consumed, and cost is low.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a sand power generation device. Background technique [0002] Since wind power generation and photovoltaic power generation are greatly affected by natural factors, firstly, it is impossible to generate relatively balanced electric energy, and secondly, it is impossible to generate electric energy all the time. This will have a greater impact on the power transmission process of the entire power grid: when there is wind and light, the power generation will be large; There is no light and the wind is relatively small, and the power generation is small). Due to the unbalanced and uncontrollable power generation of wind power and photovoltaic power generation, that is to say: when there is wind and light, wind farms or photovoltaic farms will generate a lot of electric energy, and the capacity of the transmission grid is limited, so it is impossible to receive a large amou...

This will have a greater impact on the power transmission process of the entire power grid: when there is wind and light, the power generation will be large; There is no light and the wind is relatively small, and the power generation is small)

Due to the unbalanced and uncontrollable power generation of wind power and photovoltaic power generation, that is to say: when there is wind and light, wind farms or photovoltaic farms will generate a lot of electric energy, and the capacity of the transmission grid is limited, so it is impossible to receive a large amount of electric energy within a certain period of time and deliver

Thus a considerable amount of power (peak) is wasted

Other power generation methods such as nuclear power, thermal power, hydropower, etc., although they can achieve a relatively stable transmission of electric energy, but these power generation methods will consume resources or cause environmental pollution
