A solar concentrator that can be stationary for many consecutive days

Abstract

The invention provides a solar concentrating device that can be stationary for many days, including: a reflective concentrator, a support, a light energy utilization component, and a positioning device for the reflective concentrator; Keep still; the light energy utilization component is fixed on the support, and does not move throughout the year; the reflective condenser is rotatably connected to the two support through two rotating shafts, and the axes of the two rotating shafts are located on the axis of the light energy utilization component , or near the axis, the reflective condenser can take the two rotating shafts as the axis, and change the direction of its main axis surface by external force. Between two adjustments, the reflective condenser is fixed on the reflective condenser positioning device, and continuously The day remains motionless. This concentrating device itself does not have an automatic tracking device, so its manufacturing cost is greatly reduced. Except for several to dozens of human adjustments in a year, this device remains fixed, so the system has a strong ability to resist wind and rain damage. This device only needs the user to adjust several times to dozens of times every year, and the user's labor load is also very light.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, and more specifically, relates to a solar concentrating device that can be stationary for several consecutive days. Background technique [0002] At present, people pay more and more attention to the development and utilization of solar energy technology, and the role of solar concentrated tracking technology is also increasing. In the field of photovoltaic applications, this technology can greatly save the use of photovoltaic cells; in the field of photothermal applications, this technology can increase the output temperature of solar energy and its heat utilization efficiency. For example: if you do not use concentrating technology, the solar vacuum tube water heater can reach a temperature of 80 or 90 degrees in summer, but only 50 or 60 degrees in winter. This heat production temperature can only meet the needs of daily life. The demand for hot water cannot meet the industri...

AI Technical Summary

Problems solved by technology

But doing so not only increases the cost of the solar thermal utilization system, but also increases the technical difficulty of production, use and daily maintenance of this device

Although some compound paraboloid technologies do not need automatic tracking devices to cooperate with them, which reduces technical difficulty and production costs, this technology also has some disadvantages: First, the shape of the concentrating surface is relatively complicated, and it is difficult to produce and assemble

Second, the concentration factor is not high

Three, the area of ​​the light-gathering surface used is relatively large, which increases the usage of light-gathering materials and thus increases the production cost

Fourth, the azimuth angle of this device needs to be adjusted regularly, but so far, there is still a lack of a very ideal method for adjusting and fixing the reflective condenser, so that it is easy to adjust and firm to fix
