Built-in heat-preservation effect raising automatic device of sunlight greenhouse

Abstract

The invention provides a built-in heat-preservation effect raising automatic device of a sunlight greenhouse. The device comprises a motor, guide rails, a driving shaft, a rolling wheel set, rotation wheels, guide wheels, a steel wire rope, film hanging parts and limiting ropes, wherein the motor and the driving shaft are installed on a north wall of the greenhouse along the east-west direction; the guide rails are installed on bottom ends of a framework of the greenhouse respectively along the south-north direction; the rolling wheel set sleeves the driving shaft; the guide wheels are disposed on south ends of the guide rails; the multiple rotation wheels are installed on the guide rails along the south-north direction; the film hanging parts used to hang films are disposed under the rotation wheels; the steel wire rope successively winds the rolling wheel set, the rotation wheels and the guide wheels and then returns from the guide wheels to the rolling wheel set to form a loop; the limiting ropes are in an in-series connection with all the rotation wheels which are located on the same guide rail; and the driving shaft is driven by the motor, the rolling wheel set is driven by the driving shaft to rotate and drive motion of the steel wire rope, and the limiting ropes are driven by the steel wire rope to drive reciprocating motion of the multiple rotation wheels. The device provided by the invention has the beneficial effects that automatic film covering and rolling can be implemented efficiently.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to an automatic device for heat preservation and efficiency improvement built in a solar greenhouse. Background technique [0002] The solar greenhouse has become a more profitable industry in the planting industry. However, existing solar greenhouses generally have problems of poor thermal insulation and low production efficiency. Especially in alpine regions, the cultivation of temperature-loving vegetables must rely on medium (coal, electricity, gas, etc.) heating means to increase the temperature in the greenhouse before normal production. How to upgrade the existing solar greenhouse under the premise of ensuring the improvement of economic benefits, reduction of production costs and energy saving has become an urgent problem in vegetable production. The solar greenhouse is generally facing south and facing east and west. The east, west and north sides are enclosure and ins...
