Description

Good fixing device for canopy membrane of stability Technical Field The utility model relates to the technical field of agricultural films, in particular to a fixing device for a greenhouse film with good stability. Background The greenhouse film reduces heat dissipation through forming a closed space, absorbs solar radiation energy and slowly releases the solar radiation energy, maintains stable temperature in the greenhouse, has high-quality greenhouse film light transmittance of more than 90%, allows visible light to penetrate, provides sufficient illumination for crops, enhances photosynthesis efficiency, blocks direct invasion of cold air, rainwater, snow melting and the like, reduces wind speed, and reduces risks of freezing injury, water stain and mechanical damage of crops. In plum rainy season and typhoon frequent region, the canopy film can obviously reduce the occurrence probability of diseases. The patent document with the bulletin number of CN220359790U discloses a double-layer greenhouse film structure with a fixing device, the double-layer greenhouse film structure with the fixing device consists of a greenhouse film support and a greenhouse film fixing part, the support part consists of a greenhouse arched beam processed by rectangular hollow square steel and a flexible multi-strand steel wire rope net, the fixing part consists of a pressing plate strip, a greenhouse film clamping groove and a clamp spring, the fixing part is used for fixing the components, an upper layer and a lower layer of greenhouse film through the hollow square steel by self-tapping screws, the heat loss of the greenhouse film surface can be effectively reduced, the heat insulation performance of the greenhouse is improved, and the double-layer greenhouse film structure has the characteristics of simple structure, easy installation, easy disassembly and easy film replacement, and is suitable for building the greenhouse for agriculture and fishery cultivation in high and cold areas, but the patent has the following problems in the actual use process: This take fixing device's double-deck canopy membrane structure runs through above-mentioned subassembly and upper strata, lower floor's canopy membrane through the self-tapping screw and fixes the mode together with hollow square steel for the canopy membrane when the installation, self-tapping screw passes the canopy membrane and can lead to the fact the destruction to the canopy membrane, thereby makes the canopy membrane appear tearing broken condition easily when receiving to drag, consequently makes the practicality of this take fixing device's double-deck canopy membrane structure relatively poor.
