Multi-span greenhouse capable of resisting wind, ice and snow

Abstract

A multi-span greenhouse capable of resisting wind, ice and snow comprises a basic frame, ceilings, corridors and wind-resisting heat insulation films. Each ceiling comprises two lateral ceilings. Eachlateral ceiling comprises at least one arc-shaped arching frame. The arching frames are arranged on the basic frame and arrayed longitudinally. At least one arc-shaped wind guide support is arrangedat the end of the multi-span greenhouse. The corridors are arranged between the adjacent ceilings, and are fixed to the basic frame. The width of each corridor is larger than or equal to 1.5m. The wind-resisting heat insulation films cover the ceilings and the arc-shaped wind guide supports. The multi-span greenhouse has the advantages that the lateral ceilings are provided with the arc-shaped arching frames, the arc-shaped wind guide supports are arranged at the end of the multi-span greenhouse, the wind-resisting heat insulation films are convenient to lay with radian, snow and rainwater slide down to the ground along the radian of the wind-resisting heat insulation films, accumulation of the snow and the rainwater on the wind-resisting heat insulation films of the greenhouse is reduced,and collapse of the greenhouse is avoided; heating resistance wires on the ceilings are electrified according to conditions, so that ice and snow on the greenhouse is cleaned timely and quickly, andsituations such as icing and snow accumulation of the greenhouse are avoided.

Description

technical field [0001] The invention relates to a greenhouse, in particular to a multi-span greenhouse capable of resisting wind and ice and snow. Background technique [0002] Greenhouses are an indispensable and important facility in the modern agricultural industry. Traditional greenhouses can be divided into single-span greenhouses and multi-span greenhouses, or simple greenhouses and modern greenhouses. Generally, they are made of bamboo poles, cement poles, light steel pipes or pipes. The skeleton is made into upright columns, tie rods, arch rods and pressure rods, covered with plastic film to form an arched greenhouse. Greenhouses generally cover an area of ​​1 to 3 acres and are easy to manage. When this type of greenhouse resists the wind and snow, it is usually manually removed from the greenhouse by poking or shaking the wind and snow. The workload of the operator is large, and the pressure on the plastic film of the greenhouse is large, which reduces the tempera...

AI Technical Summary

Problems solved by technology

When this type of greenhouse resists the wind and snow, it is usually manually removed from the greenhouse by poking or shaking the wind and snow. The workload of the operator is large, and the pressure on the plastic film of the greenhouse is large, which reduces the temperature of the greenhouse. Long service life, low efficiency of wind and snow removal, etc.

[0003] The modern greenhouse includes intelligent control system, seedbed system, supplementary light system, internal circulation system, external circulation system, sprinkler irrigation system, wind resistance system and other structures, but its cost is as high as several thousand yuan per square meter. , it is difficult to meet the high equipment investment cost. Therefore, it is urgent to provide a modern greenhouse with low investment cost and good wind and snow resistance.

[0004] CN 206978178 U discloses a new type of thermal insulation, wind and snow resistant ecological greenhouse, its snow resistance mechanism includes a protective plate, a movable rod, a fixed connection seat, an electric cylinder, a support rod, a baffle plate, a magnet one, a door panel, a magnet two and a bottom plate, The lower end of the protective plate is provided with a movable rod, the lower end of the movable rod is installed with a fixed connection seat, the fixed connection seat is installed on the electric cylinder, the upper end of the electric cylinder is provided with a support rod, and the upper end of the support rod is installed with a protective plate. Magnet 1 is installed on the rear end of the baffle, and the rear end of the magnet 1 is assembled with a door panel. The door panel is installed on the top of the base plate. Shake off the wind and snow, the structure of the equipment is complicated, it is inconvenient to use, and the protective plate will also block the sunlight of the ecological greenhouse, which will affect the growth rate of the crops in the ecological greenhouse
