Large-span strut-free energy-saving sunlight greenhouse

Abstract

The invention discloses a large-span strut-free energy-saving sunlight greenhouse which comprises a roof frame formed by connecting a plurality of arc-shaped arched beams through a plurality of transverse pull rods, wherein a heat preservation film-coated felt with an upward rough surface is arranged at the upper part of the roof frame; a wrapping film-coated felt is arranged on the heat preservation film-coated felt in a manner that the rough surface of the wrapping film-coated felt is downward; a forwards unfolded front slope heat preservation quilt and a backwards unfolded rear slope heat preservation quilt are arranged on the wrapping film-coated felt; greenhouse films are mounted on two sides of the heat preservation film-coated felt at the upper part of the roof frame through transverse clamping slots and longitudinal film clamping slots; and insect-proof nets and air discharging films are arranged at the front and rear lower parts of the roof frame. The large-span strut-free energy-saving sunlight greenhouse is reasonable in structure, high in heat preservation property and high in ventilating speed, and the heat preservation quilt is difficult to weather and long in service life.

Description

technical field [0001] The invention belongs to the technical field of agricultural facility engineering, in particular to a large-span energy-saving solar greenhouse without pillars. Background technique [0002] In the prior art, the solar greenhouse includes a front wall, a rear wall, two side walls and a roof. The roof is composed of several arc-shaped arches to form a roof frame, and the roof frame is covered with plastic film and Insulation quilt. It has the advantages of low cost and can increase the indoor temperature through sunlight, so it is widely used in agricultural planting greenhouses, livestock and poultry breeding pens, etc. [0003] In the solar greenhouse in the prior art, the greenhouse film is fixed by clamping grooves and springs arranged vertically and horizontally. In order to fix firmly and prevent the greenhouse film from being blown away by strong winds, the lamination line is tightened on the greenhouse film for reinforcement. Under the action ...

AI Technical Summary

Problems solved by technology

Under the action of wind force, the film pressing line rubs against the greenhouse film, which is prone to damage and affects the service life of the greenhouse film

In addition, the solar greenhouses in the prior art also generally have disadvantages such as poor thermal insulation and energy saving effect, slow ventilation and cooling speed, increased weight of the thermal insulation due to water immersion, inconvenient rolling and unwinding operation, and short service life of the thermal insulation quilt due to weathering.
