Wind-resistant plastic greenhouse

Abstract

The invention provides a wind-resistant plastic greenhouse. Wind-controlling connecting devices are arranged at the arching positions of arched supports of the plastic greenhouse respectively and usedfor limiting the arching states between the arched supports. Each wind-controlling connecting device comprises a wind-controlling trumpet, a wind pipe, a air bag pipe and a plug, wherein the air bagpipe swells after being inflated, and the plug is inserted into the air bag pipe and used for blocking an air hole of the air bag pipe. When there is strong wind, the wind enters the air pipes throughthe wind-controlling trumpets and then enters the air bag pipes so as to push the plugs in the air bag pipes out, after the plugs are removed, the air bag pipes are deflated and shrivelled, the limiting effect on the arched supports is lost, and then the arching positions of the arched supports retract to plastic greenhouse inwards due to the gravity, so that the plastic greenhouse is changed into a depressed state from the arching state, the windward area is greatly reduced, the influence of wind power to the plastic greenhouse is reduced, and the wind-resistant performance of the plastic greenhouse is improved.

Description

technical field [0001] The invention relates to a plastic greenhouse, more specifically to a wind-resistant plastic greenhouse. Background technique [0002] Plastic greenhouse is a simple and practical protective cultivation facility. my country has a vast territory and complex climate. Plastic greenhouses are used for facility cultivation of vegetables and flowers. Because of its easy construction, convenient use, and low investment, it is widely used by countries all over the world with the development of the plastics industry. Use bamboo, wood, steel and other materials, and cover with plastic film, to build an arched shed for growing vegetables, which can advance or delay the supply, increase the output per unit area, and prevent natural disasters, especially in the early spring and late autumn off-season in the northern region. Serve fresh vegetables. It plays a special and important role in alleviating the contradiction between supply and demand of vegetables in the...

AI Technical Summary

Problems solved by technology

However, when the existing plastic greenhouses are in use, because the support frame is set outward and upward, when encountering a strong wind, the wind area is large, and the support frame will loosen and swing under the influence of wind force, or even be damaged. Therefore, the existing plastic greenhouses have poor wind resistance
