Problems solved by technology

[0003] At present, the most ideal renewable energy is solar energy. The utilization of solar energy mainly includes photothermal power generation, photovoltaic power generation, solar lighting and solar cookers used in rural areas. The use of heliostats can greatly improve the utilization rate of solar energy. It is a heliostat driven by a motor, which is expensive, technically difficult, and not easy to promote, which largely limits the use of solar energy

Abstract

The invention relates to the field of solar energy utilization, and discloses a pneumatic heliostat device which comprises a horizontal base, the horizontal base is fixedly connected with a vertical stand column, the top of the vertical stand column is provided with a universal spherical hinge, the upper end of the universal spherical hinge is connected with a butterfly mirror surface, and one side of the bottom of the butterfly mirror surface is fixedly connected with a horizontal telescopic pipe. The vertical stand column is fixedly connected with one end of the pitching telescopic pipe, the other end of the pitching telescopic pipe is fixedly connected with the horizontal telescopic pipe, a hollow support is fixed to the upper edge of the butterfly mirror surface, and an air expansion cavity is fixed to the upper end of the hollow support. Sunlight is focused through the butterfly type mirror surface, when the focused light irradiates the cooling fins on the air expansion cavity along with the deviation of the sun, the cooling fins are heated to enable air in the air expansion cavity to expand, the expanded air enters the horizontal telescopic pipe or the pitching telescopic pipe through the one-way air guide valve, and the mirror surface rotates along with the sun due to the change of the length of the telescopic pipe; and a motor is not needed, so that the cost of the heliostat is reduced.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a pneumatic heliostat device. Background technique [0002] At present, energy is the number one problem in the world. Coal and oil are in short supply, and the proportion of renewable energy is far from meeting the demand. [0003] At present, the most ideal renewable energy is solar energy. The utilization of solar energy mainly includes photothermal power generation, photovoltaic power generation, solar lighting and solar cookers used in rural areas. The use of heliostats can greatly improve the utilization rate of solar energy. It is a heliostat driven by a motor, which has high cost, great technical difficulty, and is not easy to promote, which largely limits the utilization of solar energy. Contents of the invention [0004] The purpose of the present invention is to solve the following shortcomings in the prior art, apply the device of the present invention, redu...
