Pressed film rope fixing method for preventing greenhouse plastic film from rapid abrasion

Abstract

The invention provides a pressed film rope fixing method for preventing a greenhouse plastic film from rapid abrasion which aims at avoiding the condition that a greenhouse film is abraded by a pressed film rope. The method provided by the invention comprises the following steps that agricultural greenhouse frameworks are built, and then clamping slots are fixedly installed between the adjacent frameworks; plastic films are laid outside the greenhouse frameworks, the plastic films are inserted into the clamping slots, S-shaped clamp springs are clamped into the clamping slots, and the greenhouse plastic films are fixed on the clamping slots; a U-shaped clamp ring is designed according to the shape size of an upper end hole of each clamping slot, and comprises a U-shaped clamp and a rope ring; longitudinal lateral grooves are formed in the two outer sides of each U-shaped clamp, and the sizes of the lateral grooves are matched with those of openings of the clamping slots for matched use; the two bottom ends of each U-shaped clamp are designed to be tip-shaped; the rope ring is arranged on the top of each U-shaped clamp, and is longitudinally arranged along each U-shaped clamp; the U-shaped clamp is inserted into each clamping slot, and the pressed film rope penetrates through the rope ring at the top of each U-shaped clamp; and the bottom of the pressed film rope is tied tightlyto ground hooks, so that the pressed film rope can be fixed by being tightly attached to the plastic film.

Description

technical field [0001] The invention belongs to the technical field of agricultural materials, and in particular relates to a film-pressing rope fixing method for preventing rapid abrasion of greenhouse plastic films. Background technique [0002] Agricultural greenhouse technology has been widely used in agricultural production in my country, and plastic film is a commonly used material in agricultural greenhouses. The existing greenhouses are generally supported by a rigid frame, and then the plastic film is laid on the frame. In order to keep the bottom wind, a slot is specially set up at a place about 900cm away from the ground in the frame of the frame to facilitate the plastic film on the frame of the frame. Stretch, tighten, and then compress the film with a film rope to form the overall stability. However, in the actual use process, the friction between the pressure film rope and the plastic film at the position of the clamping hole caused the rapid damage of the pl...

Problems solved by technology

However, in the actual use process, the friction between the pressure film rope and the plastic film at the position of the clamping hole caused the rapid damage of the plastic film, which directly led to a drop in the temperature in the shed, and even led to the overall destruction of the plastic film; analysis The main reason is that the film-pressing rope is not tightened, and it is easy to rub and collide with the agricultural film and the slot when the wind blows. As a result, the plastic film is first worn out at the place where the film-pressing rope is in contact with the card slot and the agricultural film. Once the film is damaged, under the action of the wind, the worn part becomes the concentrated diffusion point of the wind stress, and the film is easily torn, which directly affects the safety and use of the greenhouse.
