Solar photovoltaic power generation device for smart power grid

Abstract

The invention relates to the technical field of photovoltaic power generation, in particular to a solar photovoltaic power generation device for an intelligent power grid. The device comprises a mounting plate, wherein a plurality of supporting rods with different heights are fixed at four corners of the top of the mounting plate, a photovoltaic panel is fixed at the tops of all the supporting rods, a glass plate sleeves the top of the photovoltaic panel, a plurality of first springs are fixed to the four edges of the top of the photovoltaic panel, the tops of all the first springs are jointly and fixedly connected with the glass plate, and a shaking sand removing device is installed between the bottom of a second communicating pipe and an arc-shaped plate. According to the invention, by arranging the glass plate and the shaking sand removing device, the device can drive the glass plate to shake through wind power to clean sand and dust on the top of the glass plate when the sand and dust amount is small, and can drive the glass plate to regularly vibrate through the shaking sand removing device to remove sand when the sand and dust amount is large, and collects the cleaned sand and dust, so that dust accumulation is prevented from influencing the power generation efficiency of the device.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a solar photovoltaic power generation device for a smart grid. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It is mainly composed of solar panels, controllers and inverters. The main components are composed of electronic components. Desert areas are suitable for photovoltaic power generation due to sufficient sunlight. However, when photovoltaic power generation is performed in desert areas, the high temperature and raised sand and dust in the desert are important factors affecting the efficiency of photovoltaic power generation. [0003] The prior art discloses some invention patents on photovoltaic power generation. The patent application number is CN109450372B, which discloses a desert photovoltaic power generati...

AI Technical Summary

Problems solved by technology

[0004] The photovoltaic power generation device used in the desert in the prior art is only designed for the high temperature in the desert, and when the photovoltaic power generation device is working in the desert, the sand and dust raised in the desert will fall on the top of the photovoltaic panel, thereby affecting the photovoltaic power generation. The panels are shaded, and at the same time, the sand is easy to heat up rapidly under the sun, resulting in excessive temperature and damage to the photovoltaic panels
