Automatic sunshading device for top floor of building

Abstract

The invention belongs to the technical field of building automation equipment, and particularly relates to an automatic sunshading device for the top floor of a building. The automatic sunshading device includes a bracket fixedly mounted on a roof, a sunshading mechanism and a circuit control mechanism which are mounted at the top of the bracket, and an inflatable mechanism mounted on a vertical column of the bracket, the circuit control mechanism comprises a sealing box, the sealing box is internally divided into a left chamber and a right chamber by a piston, the left inner side wall of thesealing box is fixedly connected with one end of a telescopic rod, the other end of the telescopic rod is fixedly connected with the left side wall of the piston, a heat collector located outside thesealing box and a heat dissipation layer covering the surface of the inner wall of the left chamber of the sealing box are connected into a whole, the piston is fixedly connected with a moving contactcapable of conducting electricity in an inserted mode, the right inner side wall of the sealing box is fixedly connected with a static contact capable of conducting the electricity in an inserted mode, and the right end of the moving contact is matched with the left end of the static contact. When the direct sunlight temperature is very high in summer, the circuit control mechanism controls an air pump to inflate the sunshading mechanism and prop up a sunshade for sunshading, and the automatic sunshading device does not work when the temperature is low in winter.

Description

technical field [0001] The invention belongs to the technical field of building automation equipment, and in particular relates to an automatic sunshade device for the top floor of a building. Background technique [0002] In summer, the temperature is high, and it is necessary to shade the sun to reduce the indoor temperature. In winter, the temperature is low, and it is necessary to get as much light as possible to obtain a higher indoor temperature. Due to the direct sunlight on the top floor of the building, the heat is directly transmitted to the room through the roof, resulting in high indoor temperature in summer, which affects the comfort of living. The traditional solution is to install a fixed awning on the roof. Although this method can reduce direct sunlight in summer and lower the indoor temperature, it will also block direct sunlight in winter, resulting in lower indoor temperature in winter, which also affects living. comfort.
