Description

technical field [0001] The present invention relates to a solar energy concentrating device, in particular to a solar concentrating device adopting a spoke wheel device matrix and its application. Background technique [0002] As a clean and environmentally friendly energy source, solar energy has long been devoted to its development and utilization. Especially in recent years, due to the rising oil price, the improvement of environmental protection requirements, and the limitation of atmospheric carbon dioxide emissions, countries have worked harder to carry out research on solar energy utilization. [0003] Due to the low power density of solar radiation, in order to make full use of solar energy, it is a very important technology in solar energy utilization to track the position changes of sunlight and convert the light into heat and electricity. At present, a variety of solar energy concentrating devices with different concentrating methods are in use. Overall, the foc...

AI Technical Summary

Problems solved by technology

However, a major problem in these solar energy concentrating devices is that the weight of the structure itself and the impact of the wind will increase the mass of the structure, so that the system uses more materials and costs more

For general wind force, it will twist and deform the collection bar, thus reducing the efficiency of collection

If it is a strong wind and strong wind, the whole system will be destroyed. At the same time, these collection systems cannot be protected from rain and dust, and are inconvenient to maintain, which makes the cost and cost continue to rise.

In addition, the optical system of the current solar photovoltaic power generation system is complicated, the drive is complicated, and the cost is high; moreover, the problem of heat dissipation has become a major problem that cannot be avoided in high-power focused photovoltaic power generation. The cells are easily polluted and inconvenient to clean; the overall structure is resistant Poor wind performance, etc.

[0006] It can be seen from the above that the disadvantages of the existing technology are: the structural weight of the solar energy concentrating equipment increases due to the need to meet the requirements of wind resistance; in bad weather, the concentrating surface will be distorted and deformed, and it cannot prevent rain, dust, and hail. Inconvenient maintenance, high cost and cost, complex manufacturing process, poor scalability

In addition, because the existing technology is not connected as a whole, the reflectors are only connected at the left and right positions, not at the front and rear positions, so that a grid structure cannot be formed, and a large amount of reinforced concrete needs to be placed underground for fixing, resulting in high cost

When the concentrating equipment is used for solar photovoltaics, the existing technology has not yet seen a report that can solve the heat dissipation structure well
