Film winding device with drainage function on greenhouse

Abstract

The invention discloses a film winding device with a drainage function on a greenhouse. The film winding device comprises film winding pipes and a film, wherein the film winding pipes are arranged on a greenhouse arch frame, and the film is wound on the film winding pipes. A water channel parallel to the film winding pipes is formed in the upper portion or the sidewall on one side of the greenhouse arch frame, the inner wall of the water channel is provided with clamping grooves for clamping the film winding pipes, and the film on the film winding pipes can bypass the sidewall of the water channel to lay on the greenhouse arch frame. The film winding device with the drainage function on the greenhouse has the advantages that the water channel is arranged on the upper portion or the sidewall of the greenhouse, and the clamping grooves for fixing the film winding pipes are formed in the water channel, so that fixation of the film winding pipes and the film is facilitated, wind resistance of the film winding pipes and the film is enhanced, rainwater can be drained through outlets at two ends of the water channel in rainy days, greenhouse drainage effects are improved, forming a high-humidity environment in the greenhouse is avoided, and greenhouse planting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cultivating flowers, vegetables or rice in containers, hotbeds or greenhouses, in particular to a rolling film device with drainage function arranged on a greenhouse. Background technique [0002] The existing greenhouse infrastructure is composed of brackets and arches arranged on the brackets. Films are laid around the brackets and on the arches by rolling film devices to form a closed greenhouse space. The greenhouses with the existing structure have the following defects: ventilation at the top of the greenhouse The height of the mouth should not be higher than 1.2 meters. When the opening width exceeds 1.2 meters, there will be no tension at both ends of the film in the film rolling device, resulting in poor anti-storm ability, and the film rolling device and film are easily damaged under the attack of the storm; When the height of the air vent at the top of the greenhouse should not be higher than 1...

[0002] The existing greenhouse infrastructure is composed of brackets and arches arranged on the brackets. Films are laid around the brackets and on the arches by rolling film devices to form a closed greenhouse space. The greenhouses with the existing structure have the following defects: ventilation at the top of the greenhouse The height of the mouth should not be higher than 1.2 meters. When the opening width exceeds 1.2 meters, there will be no tension at both ends of the film in the film rolling device, resulting in poor anti-storm ability, and the film rolling device and film are easily damaged under the attack of the storm; When the height of the air vent at the top of the greenhouse should not be higher than 1.2 meters, high temperature and high humidity environment will easily form in the greenhouse. The normal formation of pigments affects its commodity value; high humidity can easily bring mold, viruses, leaves and roots to rot and cause death to plants
