Solar photo-thermal device

Abstract

The invention discloses a solar photo-thermal device which comprises a heat collecting container, a guiding support, a movable light collecting plate and two reflection plates. The guiding support is arranged on the heat collecting container and comprises a base frame part and a swinging frame part, wherein the swinging frame part is driven by a driver to be capable of performing reciprocating rotation swinging displacement movement. The movable light collecting plate is arranged at the top end of the swinging frame part to enable the movable light collecting plate to be capable of having the movable performance along with the rotation swinging displacement of the swinging frame part, the movable light collecting plate is provided with a light collecting part to enable received sunlight to be downwards refracted to form collected light beams, the reflection plates are arranged on the two opposite sides of the guiding support in a pivoted mode, and mirror surfaces are arranged on the opposite inner sides of the reflection plates to be used for reflecting light. The problem of burning caused by the fact that the collecting light beams are shifted to the outside can be effectively solved, and the practical advancements of greatly improving the use safety, the thermal energy capturing rate and the use performance of the solar photo-thermal device are achieved.

Description

technical field [0001] The invention relates to a solar photothermal device, in particular to a solar photothermal device in which reflection plates are pivotally arranged on two opposite sides of a guide bracket. Background technique [0002] According to, in view of the importance of sustainable development of the earth, the development of green energy is a top priority, and among green energy, solar energy is an inexhaustible and non-polluting green energy. Therefore, in view of the increasingly serious situation of the current "greenhouse effect", using solar energy as much as possible is a good way to benefit mankind. [0003] Currently known and commonly used solar devices are solar photovoltaic modules (or solar panels), whose function is mainly to convert light energy into electrical energy by absorbing sunlight, and store the electrical energy to assist or replace it. Traditional electricity; this is a well-known way to use solar energy; however, in addition to bei...

Problems solved by technology

[0006] Furthermore, even if the problem of the failure of the aforementioned sun-tracking induction controller is eliminated, when the movable concentrating plate swings to a certain deflection angle (that is, in the morning and evening hours), its concentrating light beam will not be able to fall on the center of the heat collecting container. , which in turn causes the effective heating time of the heat collecting container to be shortened, and the heat energy extraction rate is greatly affected.
