Description

Technical Field

[0001] This utility model belongs to the field of rain shelter film technology, specifically relating to a single-layer film rain shelter. Background Technology

[0002] In agricultural production, single-layer film generally refers to a thin film composed of a single material or composite material. Rain shelters, on the other hand, are practical facilities specifically designed for agricultural production. They employ a manually retractable structure, slidingly fixed to pre-installed cables, allowing farmers to easily adjust the coverage area and position of the shelter according to weather conditions or crop needs. Using a single-layer film as the covering material provides excellent light transmittance, ensuring crops receive ample sunlight while being sheltered from rain. Furthermore, this film material also possesses durability and anti-aging properties, making it widely used in orchard protection, vegetable cultivation, and other fields.

[0003] While existing single-layer membrane rain shelters offer advantages such as high flexibility and easy installation, the area expands when the single-layer membrane is unfolded. Under strong winds and rain, the wind pressure, resistance, and thrust it bears are excessive. In order to ensure the rain shelter effect, its ventilation capacity is poor, which may cause the single-layer membrane to deform or break under strong winds, resulting in property damage. Utility Model Content

[0004] The purpose of this invention is to provide a single-layer film rain shelter that can arch the film upwards, has a relatively low weight, and can adjust the fiber thread tubes to extend outwards to support the film after the film stretches, making the film and fiber rods fit together better and less prone to the problem of the rain shelter falling apart.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A single-layer membrane rain shelter includes a rain shelter roof, the rain shelter roof including at least two oppositely arranged membranes, with a ventilation section between the membranes for air circulation.

[0007] The outer side of the canopy film is provided with multiple external rods, and fiber rods are provided between the external rods to arch the canopy roof upwards.

[0008] The opposite sides of the external rod section are open to accommodate the ends of the fiber rods.

[0009] The fiber rod includes a main rod body, at least one end of which is provided with a threaded portion. A fiber threaded tube is provided on the outside of the threaded portion, which can be rotatably extended along the radial direction of the main rod body. The end of the fiber threaded tube is inserted into the interior of the outer rod portion.

[0010] The ventilation section is the gap between the film sheets.

[0011] The greenhouse film has perforations equidistantly spaced along the radial direction on opposite sides, and binding devices are provided in the perforations of adjacent greenhouse films to fix the greenhouse film.

[0012] The spacing between the outer rod sections is less than the length of the fiber rod.

[0013] A rod threading rope is provided on the opposite side of the greenhouse film, and the main rod passes through the rod threading rope for positioning.

[0014] The outermost edge of the greenhouse film is provided with a sliding buckle.

[0015] An elastic buckle is provided in the middle of the lower part of the greenhouse film, and the main body of the fiber rod is inserted into the elastic buckle. The length of the elastic buckle is less than the length of the outer curved surface of the main body.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This utility model adopts a design scheme of fiber rods combined with greenhouse film, which is relatively lightweight and does not easily put strong pressure on the greenhouse frame, thus making the construction cost of the greenhouse frame lower.

[0018] The ventilation section between the greenhouse films in this invention facilitates ventilation for crops inside the greenhouse, which is beneficial for crop growth.

[0019] In this invention, the two ends of the fiber rod are inserted into the outer rod part on the side of the greenhouse film, which can arch the greenhouse film upward and provide good support. The overall weight of the greenhouse film is light, which is more conducive to ventilation between crops when there is a slight breeze.

[0020] This invention allows for the adjustment of the fiber spiral tubes to extend outwards after the greenhouse film stretches, thus supporting the film and making the film and fiber rods fit together better, reducing the risk of the awning falling apart.

[0021] This invention utilizes a combination of a pole-threading rope and an elastic buckle to fix the fiber pole, enabling the fiber pole to better integrate with the greenhouse film and support the awning, resulting in greater overall stability. Attached Figure Description

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0031] like Figure 1-6 As shown, a single-layer membrane rain shelter includes a rain shelter roof 1, which includes at least two oppositely arranged membranes 2, with a ventilation section 3 between the membranes 2 for air circulation; the overall design adopts a fiber rod combined with the membranes 2, which is relatively lightweight and does not easily put strong pressure on the greenhouse frame, thus reducing the construction cost of the greenhouse frame; the membrane 2 can be a woven membrane.

[0032] See attached document Figure 1-2 Ventilation section 3 is the gap between the greenhouse films 2. The ventilation section between the greenhouse films 2 is conducive to the ventilation of crops inside the greenhouse and to crop growth.

[0033] See attached document Figure 2-3 Perforations 4 are equidistantly opened along the radial direction on opposite sides of the greenhouse film 2, and binding pieces 5 are provided in the perforations 4 of two adjacent greenhouse films 2 for fixing the greenhouse film 2.

[0034] See attached document Figure 2-3 The greenhouse film 2 is provided with a rod rope 8 on the opposite side. The main rod 10 passes through the rod rope 8 for positioning. The two adjacent greenhouse films are connected by using the rod rope 8 in combination with the perforation 4. The connection method is simple and the cost is lower.

[0035] See attached document Figure 2The outermost edge of the outermost greenhouse film 2 is provided with a sliding buckle 9. The sliding buckle 9 is used to connect the greenhouse film 2 to the greenhouse frame. A long strip component is attached to the crop, which can be a rope such as a steel wire rope or a metal rod. The length of the sliding buckle 9 is set to be greater than the circumference of the outer curved surface of the rod. Combined with the fact that the greenhouse film 2 is a deformable material and has no radial limiting or positioning components, the greenhouse film 2 can be rolled up to one side along the long strip component in the indicated weather to allow the crop to be ventilated and exposed to sunlight, which is more conducive to the growth of the crop.

[0036] See attached document Figure 4-5 The outer side of the greenhouse film 2 is provided with multiple external rods 6, and fiber rods 7 are provided between the external rods 6 to arch the canopy roof 1 upwards; the two ends of the fiber rods 7 are inserted into the external rods 6 on the side of the greenhouse film, which can arch the greenhouse film 2 upwards and play a good supporting role. The greenhouse film 2 is lightweight and is more conducive to ventilation between crops when there is a slight breeze.

[0037] See attached document Figure 1 , 4 -5, the outer rod portion 6 is open on the opposite side to accommodate the end of the fiber rod 7. The outer rod portion 6 can be made of a long strip of nylon webbing and sewn onto the greenhouse film 2 along the side of the nylon webbing. The nylon webbing on the greenhouse film 2 is kept open at one end facing inward, and this opening is used to accommodate the fiber rod 7.

[0038] See attached document Figure 5-6 The fiber rod 7 includes a main rod body 10, at least one end of which is provided with a threaded portion 11. The outer side of the threaded portion 11 is provided with a fiber threaded tube 12 that can be rotatably extended along the radial direction of the main rod body 10. The end of the fiber threaded tube 12 is inserted into the interior of the outer rod portion 6. After the greenhouse film 2 stretches, the fiber threaded tube 12 can be adjusted to extend outward to support the greenhouse film 2, so that the greenhouse film 2 and the fiber rod 7 fit together better and are less likely to fall apart.

[0039] Furthermore, in order to increase the coefficient of friction between the fiber threaded tube 12 and the outer rod portion 6, making it less likely for them to come loose, a corresponding friction protrusion can be provided on the outside of the fiber threaded tube. The friction protrusion can be a protruding arc shape or a triangular cone block, which is used to make the connection between the fiber threaded tube 12 and the outer rod portion 6 more stable.

[0040] See attached document Figure 1 , 4 -5. The spacing of the outer through rod 6 is less than the length of the fiber rod 7. The fiber rod 7 can fully expand the outer through rod 6 and is not easy to fall apart.

[0041] See attached document Figure 4An elastic buckle 13 is provided in the middle of the lower part of the greenhouse film 2. The main body 10 of the fiber rod 7 is inserted into the elastic buckle 13. The length of the elastic buckle 13 is less than the length of the outer curved surface of the main body 10. By using the rod rope 8 and the elastic buckle 13 to fix the fiber rod 7, the fiber rod 7 can be better combined with the greenhouse film 2 to support the canopy, and the overall stability is higher.

[0042] The working principle of this utility model is as follows: During installation, the two greenhouse films 2 are tied together as a whole by the binding piece 5, and then the fiber threaded tube 12 is installed on the main rod body 10. The total length of the fiber rod 7 is adjusted according to the width of the greenhouse film 2. The two ends of the fiber rod 7 are installed into the outer rod part 6 and pass through the rod rope 8 and elastic buckle 13 to limit the fiber rod 7 to the bottom of the greenhouse film 2. The rod-shaped object is inserted into the sliding buckle 9 so that the greenhouse film 2 can be erected above the crops.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
