Rainwater diversion facility for breeding greenhouse

Abstract

The invention relates to a rainwater diversion facility for a breeding greenhouse. The rainwater diversion facility comprises first clip members, second clip members and a diversion black film, wherein the first clip members and the second clip members are mounted on a steel frame of a greenhouse in an up-down spacing manner in the length direction of the breeding greenhouse; edges of a transparent plastic film of the breeding greenhouse are fixed to the first clip members and the second clip members; when the diversion black film is laid to a fixed foundation between every two adjacent breeding greenhouses, the edges on two sides of the diversion black film are separately fixed on the second clip members of the breeding greenhouses on two sides and are attached to the inner side surface of the transparent plastic film; and when the diversion black film is laid to the fixed foundation in the side direction of the breeding greenhouse at an edge position, the upper edge of the diversionblack film is fixed to the second clip members of the edge breeding greenhouse and is attached to the inner side surface of the transparent plastic film, and the lower end of the diversion black filmis fixed on the base part of the edge fixed foundation. Through the adoption of the rainwater diversion facility disclosed by the invention, damage caused by that the fixed foundation (earth dyke) inthe side direction of the breeding greenhouse is subjected to rain wash can be effectively avoided, and the wind and rain resistance capacity of the breeding greenhouse is improved.

Description

technical field [0001] The invention belongs to the technical field of rainwater diversion in a breeding greenhouse, and in particular relates to a rainwater diversion facility in a breeding greenhouse. Background technique [0002] Plastic greenhouse farming is a new farming method that has emerged in recent years. Plastic greenhouses are constructed by excavating ponds in the breeding area, building steel frames above the ponds, and covering the steel frames with transparent transparent plastic films. The end of the film is buried in a pre-excavated deep ditch of about 20 cm on the pond ridge, and the overlying soil is fixed. Compared with traditional outdoor pond culture, due to the construction of plastic greenhouses above, the water environment in the pond is less affected by external weather changes, and the transparent plastic film can increase the water temperature of the pond, which greatly advances the time for breeding seedlings, speeds up the growth of breeding o...

AI Technical Summary

Problems solved by technology

[0004] At present, some farmers build cement on the surface of the pond ridge of the greenhouse to protect it, which can achieve good results, but this method is expensive, and the hardened cement surface will be deformed and cracked after long-term trampling and high-temperature sunlight. The thatch growing on the ridge will also cause damage to the cement layer. When it rains, the rainwater will flow into the cement gap and the protective effect will be greatly reduced. It will be time-consuming and labor-intensive to repair later, and the cost will be high

Therefore, at present, farmers mainly repair the pond ridges and greenhouses after the rain, and there is no other better solution.
