Active solar heat collector

Abstract

An active solar heat collector comprises a light tracking portion, a heat collection portion and a heat storage portion; the light tracking portion comprises an upper box and a lower box; a swing mechanism is respectively arranged in the upper and lower boxes; the heat collection portion comprises a tracker head; the tracker head top plate is provided with a sun light entering hole; a top solar cell is arranged outside the tracker head top plate; a bottom solar cell is arranged on a bottom plate inner surface; the tracker head bottom surface is fixedly connected with the top of the upper box swing mechanism; the upper box bottom is fixedly connected with the top of the lower box swing mechanism; the heat storage portion comprises a water box and an electric heater; the bottom solar sell is respectively connected with a lower box motor and an upper box motor through wires; the top solar cell is connected with the heat storage portion electric heater through a wire. The advantages are that the active solar heat collector is simple in structure, easy to operate, can adjust the temperature in a green house, thus greatly saving labor and coal resources, and protecting the environment.

Description

technical field [0001] The invention relates to the field of solar energy utilization calculation, in particular to a solar heat collecting device. Background technique [0002] The solar greenhouse in the severe cold area is a high-input and high-output industry. The goal of planting crops in the cold season is achieved by artificially building a suitable growth environment for the crops in the cold season. The existing solar greenhouse is a passive solar house, which relies on its own structure to absorb solar radiation energy, increases the temperature of the greenhouse, and enables crops to grow in cold winter without heating or only needs a small amount of heating. The disadvantage of existing solar greenhouses is that in winter, the amount of sunlight absorbed by the structure of the passive greenhouse alone cannot meet the temperature required for the growth of crops in the greenhouse. Risk of freezing to death. In the prior art, solar heat collectors are used for h...

The disadvantage of existing solar greenhouses is that in winter, the amount of sunlight absorbed by the structure of the passive greenhouse alone cannot meet the temperature required for the growth of crops in the greenhouse. risk of freezing to death

In the prior art, solar heat collectors are used for heating. The disadvantage of solar heat collectors is that all solar heat collectors are fixed heat collectors, and fixed heat collectors cannot optimize the heat collection effect in any lighting stage.

[0003] In order to increase the temperature of the greenhouse, some greenhouse growers also use furnace heating to increase the temperature of the greenhouse, which wastes non-renewable resources and pollutes the environment.
