Shading device of solar heat collector

Abstract

The invention discloses a shading device of a solar heat collector. A bracket (3) is installed at the top of a base (2); rails (4) are installed at two sides of the bracket (3); each rail (4) is higher than the heat collecting surface of a solar heat collector (1); a remote control receiver (7), a cell (9) and a motor (10) which are mutually connected into an electric loop are installed on the bracket (3); a transmission tube (5) is sleeved outside the motor (10) and is connected with the shaft of the motor (10); one end of a shading curtain (6) is connected with and wound on the transmission tube (5); and two sides of the shading curtain (6) are inserted into the rails (4) at the two sides of the bracket (3). The invention intelligently realizes the purposes of opening and closing the shading device, prevents the solar heat collector from being in a high temperature state for a long time, prevents the liquid in the solar heat collector from being gasified, ensures the safe operation of a system, and prolongs the service life of the system.

Description

technical field [0001] The invention relates to a sunshade device, in particular to a sunshade device for a solar heat collector. Background technique [0002] Solar collectors provide us with hot water and heat supply through the action of sunlight, but at a certain time, if the solar collectors are not required to provide heat, the solar collectors will still be exposed to the sun , so that the liquid in the collector reaches the level of vaporization, thereby generating unnecessary air pressure in the system, causing the system to remain in a high temperature and pressurized state for a long time, affecting the life and safe operation of the system. Contents of the invention [0003] The object of the present invention is to: provide a sunshade device for a solar collector, install the sunshade device on the solar collector, and when the solar collector is not required to provide heat energy, the intelligent control sunshade device is opened to overcome the problem of t...
