Solar tracking photovoltaic generating device

Abstract

The invention provides a solar tracking photovoltaic generating device, and aims to solve the technical problem of automatic liquid adding of a first drop leaking barrel. The device comprises an installing base, a photovoltaic plate, a counterweight unit, a first drop leaking unit, a second drop leaking unit, a cleaning roller and an adjusting unit, an electromagnet generates a magnetic force to absorb a piston unit through a current generated after power generation by employing the photovoltaic plate, liquid in the first drop leaking barrel can flow into a second drop leaking barrel, the rotation of the photovoltaic plate is controlled, after the power generation of the photovoltaic plate is stopped, there is no current passing through the electromagnet, the electromagnet loses magnetism,the piston unit falls back to press the liquid in the second drop leaking barrel back to the first drop leaking barrel, and the technical effect of automatic recycling of the liquid is realized; andthe cleaning roller is driven to clean the photovoltaic plate by employing up and down movement of the piston unit so that dust collection of the photovoltaic plate is avoided, and the absorption of the solar energy for the photovoltaic plate is not influenced.

Description

[0001] machine technology [0002] The invention relates to the technical field of photovoltaic applications, in particular to a solar tracking photovoltaic power generation device. Background technique [0003] In today's world, the energy crisis and environmental pollution problems have attracted more and more attention. As a new type of renewable energy, solar energy is widely used due to its environmental friendliness. Solar energy has "low energy density, intermittent, spatial distribution Therefore, higher requirements are put forward for solar energy utilization technology. Improving the utilization rate of solar energy is the focus and difficulty of current solar energy utilization technology. [0004] Improving the utilization rate of solar energy can start from two aspects, one is to improve the acceptance efficiency of solar energy; the other is to improve the energy efficiency characteristics of solar energy utilization devices. Improvements to improve solar energ...

AI Technical Summary

Problems solved by technology

[0005] No matter what kind of solar device, when the sun receiving device can always keep perpendicular to the sun's rays, the utilization rate of solar energy per unit area can be greatly improved. In recent years, many researches in this area have been carried out at home and abroad. Professor SUM Hui of the University of Hong Kong The relationship between the sun angle and the energy acceptance rate was studied, and it was found that: after implementing the sun tracking technology, the solar energy utilization rate increased by 37.7%. Among the existing sun tracking technologies, the two-axis automatic tracking research is the most, and it can track the sun at the same time. The azimuth and altitude angles make the sunlight always irradiate the solar collector vertically, which greatly improves the utilization rate of solar energy. Although the two-axis tracking effect is good, its structure is complex, the tracking motor power is large, the device cost is high, and the mechanical wear is large, which is not suitable for Large-scale use in remote areas

[0006] In the Chinese patent with the patent number CN103049000A, a dripping photovoltaic power generation device is disclosed, which is provided with a liquid tank, and then the liquid tank is connected to the photovoltaic panel through a rope and an elastic device, and the liquid tank is used in the process of dripping liquid. The change in quality drives the rotation of the photovoltaic panel, which solves the technical problem of the photovoltaic panel tracking the sun. However, the liquid in the liquid tank needs to be added manually or by other means after the light drips, which is very cumbersome
