Pyramid sun power automatic focusing system

Technical field

The present invention is the formation that the inclination that utilizes solar energy automatically solar collector or solar-energy light collector to be carried out to position as power changes to regulate optically focused focus, is the state-of-the-art technology field that sun power utilizes.

Background technology

A lot of Salar light-gathering collectors, as: the Salar light-gathering collector of lenticular mode, concave mirror formula Salar light-gathering collector, these two kinds of solar collectors can be gathered into focus large area sunray parallel and that come and produce very large high temperature to meet people's needs.But the sun is constantly to move variation, this makes support bracket fastened sun collector can not maintain unceasingly the formation of focus, and this has just produced the problem of solar collector being carried out to the adjusting of position.

For the adjusting of solar collector position, there are at present two kinds of feasible methods: manual shift, utilize manpower immediately to regulate with the variation of position of sun; Electrical apparatus electric power regulates, and utilizes electronic device to handle electric power the variation of position of sun is regulated immediately.The object that we utilize sun power is to save artificial and electric power, and the energy that we should directly utilize the sun carries out instant automatic adjusting as the Variation Features of power and the sun.

Summary of the invention

I can carry out from motion tracking the variation of position of sun by the pyramid sun power automatic focusing system of invention, can also directly utilize solar energy, as power, solar collector is carried out to instant position regulates automatically, make Salar light-gathering collector can maintain the formation of focus, how can it accomplish? the present invention's taked technical scheme of dealing with problems is: Salar light-gathering collector bottom arranges four pressure liftable devices as support column, the pyramid solar collector that another is fixed on ground is set on the side of Salar light-gathering collector, pyramid solar collector is slapped together by the gas storehouse of four arris edge shapes, between four gas storehouses and four pressure liftable devices, with high-pressure air pipe, be communicated with respectively.When the axis on pyramid intermediate vertical ground is parallel with sunray, i.e. noon, Salar light-gathering collector energy optically focused sunray becomes minimum focus, and the suffered solar radiation situation of pyramidal four faces is at this moment identical.But, variation along with the time, there is variation in sunray, pyramidal axis is no longer parallel with sunray, there is variation in the suffered solar light irradiation intensity of pyramidal four faces, the energy that gas in the gas storehouse of formation pyramid opposite obtains is different, gas pressure intensity in four gas storehouses starts to produce different variations, due between gas storehouse and pressure liftable device, there is high-pressure air pipe to be communicated with, this pressure change makes four pressure liftable devices of Salar light-gathering collector bottom obtain the power that oscilaltion regulates, the result regulating is that Salar light-gathering collector is followed sun skew direction, make Salar light-gathering collector can continue to maintain the formation of focus.

Four gas storehouses in pyramid solar collector in pyramid sun power automatic focusing system are metal gas sealing storehouses that size shape is identical, four gas storehouses have insulation material layer to be separated by each other, and the triangle heat-absorbent surface that pyramidal four sides are respectively each gas storehouse forms.It is thing easily that four cusped edge dihedral gas storehouses have scrabbled up a Pyramid, between them, there is insulation material layer to make can not carry out heat transmission between them, the solar energy that four gas storehouses obtain be constantly change and thing opposite be not identical because the position of the sun is in constantly changing.The high density of metal makes the thermal conduction capability of metal very quick, gas in gas storehouse is heated the variation that produces pressure very soon, and gas volume variation with temperature in each gas storehouse is very obvious, responsive, this all makes pyramid sun power automatic focusing system of the present invention have sensitivity, accurate modulability.

In pyramid sun power varitrol pyramid solar collector be fixed on ground, and Salar light-gathering collector is can be eastwards under the support of four pressure liftable devices, south, west, north four direction tilt variation, these four pressure liftable devices obtain the different air pressure change in each gas storehouse in pyramid by high-pressure air pipe, the different adjustable heights of four pressure liftable devices will make Salar light-gathering collector angle of inclination, and the angle of this inclination is just identical with the angle of inclination of the sun, Salar light-gathering collector can constantly maintain optically focused parallel and large area sunray that come is become to focus.
