Technical Field

The invention relates to the field of solar heat collection, in particular to a two-dimensional tracking solar heat collector.

Background

For many years, solar energy has not been used substantially in heating, and low heat collection efficiency is a major factor.

The main reason for the low heat collection efficiency is that the surface of the sunlight collection device is made of glass, and before the sunlight heat conversion, the glass surface refracts sunlight and partial energy is carried away by the refraction.

The irradiation angle of the sunlight changes every moment, and the sunlight collecting device is inevitably shielded by the sunlight.

When a heat collecting device is paved, a large amount of land area is occupied by solar heat collection.

Disclosure of Invention

The technical problem to be solved by the present invention is to overcome the above disadvantages and to provide a two-dimensional tracking solar thermal collector.

In order to solve the technical problems, the invention adopts the technical scheme that: the heat collector support and the sunlight collecting device bracket are connected in a rotating mode, the length of the heat collector support can be determined according to the height of the sunlight collecting device, for example, some users who breed greenhouses and occupy small space need the suspended installation of the sunlight collecting device, and the problem can be solved as long as the length of the heat collector support is increased.

The sunlight tracker respectively sends instructions to the vertical driving box and the horizontal driving box according to the change of the sunlight irradiation angle.

When the sun rises, the tracker energizes the positive rotation end of the motor of the vertical driving box to drive the vertical driving ejector rod to rise, so that the upper part of the collecting device bracket is pushed to rise, the collecting device bracket rotates around the vertical rotating shaft in the positive direction by a certain angle, and the collecting device and the sunlight keep vertical irradiation in the vertical direction.

When the sun descends, the tracker energizes the reverse rotation end of the motor of the vertical driving box to drive the vertical driving ejector rod to descend, so that the upper part of the collecting device bracket is pushed to descend, the collecting device bracket rotates reversely for a certain angle around the vertical rotating shaft, and the collecting device and the sunlight are always vertically irradiated in the vertical direction.

When the sun changes from east to west, the tracker energizes the positive rotation end of the motor of the horizontal driving box to drive the horizontal driving gear to rotate positively, so that the bracket of the collecting device rotates positively for a certain angle around the horizontal rotating shaft, and the collecting device and the sunlight keep vertical irradiation in the horizontal direction.

Before the sun rises the next day, the tracker energizes the reverse rotation end of the motor of the horizontal driving box to drive the horizontal driving gear to reversely rotate, so that the bracket of the collecting device reversely rotates for a certain angle around the horizontal rotating shaft, and the collecting device returns to the initial position of rising the sun and the sunlight keeps vertical irradiation in the horizontal direction.

The water inlet and the water outlet of the sunlight collecting device are connected with the water delivery hose and the water delivery main pipe, so that the function of water circulation of the heat collector in a dynamic state is solved.

The invention overcomes the defect of low heat collection efficiency, and tests prove that the heat collection efficiency is doubled compared with that of a non-dynamic heat collector, so that the solar heat collector is very suitable for popularization of large-scale solar heating.
