Abstract

The invention relates to the technical field of agricultural engineering, and provides an external thermal insulation device. The external thermal insulation device is used for conducting thermal insulation on a glass greenhouse. The device comprises a thermal insulation piece, a winding mechanism and a drawing mechanism, wherein the thermal insulation piece is used for being laid on a glass boardof the glass greenhouse; the winding mechanism is arranged at the bottom of the glass board and connected with a first side edge of the thermal insulation piece, and the winding mechanism is used forwinding the thermal insulation piece up; the drawing mechanism is arranged at the top of the glass board; a second side edge of the thermal insulation piece is connected with the drawing mechanism, and the drawing mechanism is used for drawing the thermal insulation piece and making the thermal insulation piece spread and laid on the glass board. By installing the external thermal insulation device on the outer side of the top of the glass greenhouse, the winding mechanism winds the thermal insulation piece up, it is achieved that the glass greenhouse is exposed to the sunlight, the glass greenhouse absorbs heat, the drawing mechanism draws the thermal insulation piece out of the winding mechanism, and it is achieved that the glass greenhouse is covered with the thermal insulation piece.The glass greenhouse dissipates less heat, and thermal insulation is achieved. The heat storage capacity of the glass greenhouse is improved, the structure is simple and compact, and the thermal insulation effect is good.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to an external thermal insulation device. Background technique [0002] With the continuous development of facility agriculture, the area of ​​facility agriculture in my country is increasing day by day. Among them, the common ones are solar greenhouses and glass greenhouses. The light-transmitting material used in glass greenhouses is glass, and solar greenhouses mostly use plastic films or solar panels. In comparison, the light transmittance of glass is much higher than that of plastic films and solar panels, and its service life is longer. At the same time, the space of glass greenhouses is larger, which is suitable for mechanized production operations. Therefore, the development of glass greenhouses in recent years is also very quickly. [0003] However, compared with the solar greenhouse, the glass greenhouse has obvious disadvantages in terms of heat preservati...
