Rainwater diversion facility for breeding greenhouse

Abstract

The invention relates to a cultivation greenhouse rainwater diversion facility which comprises a first fastener, a second fastener and a diversion black film, the first fastener and the second fastener are vertically mounted on a greenhouse steel frame at intervals in the length direction of a cultivation greenhouse, and the edge of a transparent plastic film of the cultivation greenhouse is fixed to the first fastener and the second fastener. When the flow guide black film is laid on the fixed foundation between the adjacent cultivation greenhouses, the edges of the two sides of the flow guide black film are fixed to the second buckles of the cultivation greenhouses on the two sides respectively and attached to the inner side face of the transparent plastic film, and when the flow guide black film is laid on the fixed foundation in the lateral direction of the cultivation greenhouses at the edge position. The upper edge of the flow guide black film is fixed to a second buckle of the edge cultivation greenhouse and attached to the inner side face of the transparent plastic film, and the lower end of the flow guide black film is fixed to the base portion of the edge fixing foundation. According to the invention, the fixed foundations (banks) between the breeding greenhouses and in the lateral direction can be effectively prevented from being washed by rainwater and damaged, and the wind and rain resistance of the breeding greenhouses is improved.

Description

[0001] This application is a divisional application for the invention patent of the parent application named "Rainwater Diversion Facilities for Breeding Greenhouses"; the application number of the parent application is: CN201911221317.7; the application date of the parent application is: 2019.12.03. technical field [0002] The invention belongs to the technical field of rainwater diversion in aquaculture greenhouses, and in particular relates to a rainwater diversion facility in aquaculture greenhouses. Background technique [0003] Plastic greenhouse farming is a new aquaculture 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 cu...

Problems solved by technology

[0005] 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.
