Description

Technical Field

[0001] The utility model relates to the field of greenhouse, in particular to an anti-friction film protection structure and a multi-span thin-film greenhouse. Background Art

[0002] The windproof skirt film is a section of film used at the bottom of the ventilation rolling film window of the agricultural planting greenhouse, and is laid above the roof arch bar. Its main function is that when the greenhouse ventilation rolling film is lowered, it overlaps with the bottom windproof skirt film to play a role in wind prevention, improve the heat preservation of the greenhouse, and thus more effectively protect the growth environment of crops. At the overlapping part of the traditional roof rolling film bar and the roof arch bar, the rolling film bar will move up and down under the action of wind. The contact between the windproof skirt film and the roof rolling film bar is hard-to-hard contact, resulting in a high friction coefficient, which accelerates the wear of the windproof skirt film. The contact between the windproof skirt film and the roof arch bar and the roof rolling film bar is mostly point contact or line contact, and the contact area is small, which easily leads to local stress concentration, so that the windproof skirt film bears a large pressure at certain points or lines, and is thus more likely to be damaged. Moreover, the roof arch bar and the rolling film bar are mostly made of hard materials, and the contact with the windproof skirt film is likely to cause damage to the film, further shortening its service life. If damage occurs, due to the limitation of the contact method, it may be difficult to quickly locate and replace the damaged part, and the entire windproof skirt film must be replaced, increasing the difficulty and cost of maintenance. Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0003] Purpose of the utility model: In order to overcome the above deficiencies, the purpose of the present utility model is to provide an anti-friction film protection structure and a multi-span thin-film greenhouse. In this anti-friction film protection structure, the windproof skirt film is located between the roof rolling film bar and the film protection component. Through cooperation with the film protection component, the friction with other components is reduced, and its own service life is prolonged. The anti-friction film protection structure is provided on the greenhouse.

[0004] Technical solution: In order to achieve the above purpose, the present utility model provides an anti-friction film protection structure, including: a film protection component, which is composed of a pipe clamp component and a film protection component. The pipe clamp component is provided on the roof arch bar, and the film protection component is provided on the pipe clamp component, and the film protection component is in a flat plate shape and is in surface contact with the windproof skirt film. The solutions on the market are all direct contact between the film and the bar, that is, surface-to-line contact or surface-to-point contact, while the solution we adopt is that the film contacts the film protection component, which is equivalent to surface-to-surface contact. The surface-to-surface contact method can distribute the pressure more evenly, reduce hard friction, thereby reducing the friction coefficient, reducing wear, and can also more effectively disperse stress, avoid local stress concentration, and improve the durability of the windproof skirt film.

[0005] Furthermore, the above-mentioned pipe clamp component is in the shape of a circular tube, and there is a notch on one side thereof. The distance between the notches is smaller than the cross-sectional width of the roof arch bar. The notch is widened to clamp the roof arch bar into the pipe clamp component. There is a notch on one side of the pipe clamp component. This design allows the pipe clamp component to have a certain elasticity and deformability. The existence of the notch enables the pipe clamp component to adapt to roof arch bars of different diameters to achieve a limiting effect without applying too much force. The distance between the notches is smaller than the cross-sectional width of the roof arch bar. Such a design ensures that when the notch is widened, the roof arch bar can be firmly clamped into the pipe clamp component to achieve stable limiting.

[0006] Furthermore, the above-mentioned pipe clamp component is made of rigid PVC. The rigid PVC material enables the limiting component to be fixed more firmly on the roof arch bar.

[0007] Furthermore, the above-mentioned protective film component is made of rigid PVC. Rigid PVC is easy to be processed into various shapes and sizes and has a low cost.

[0008] Furthermore, the above-mentioned protective film component is made of a soft material. The soft material can more effectively reduce the wear of the windproof skirt film and extend its service life. It can be made of silica gel material, rubber material, soft PVC, etc.

[0009] Furthermore, there is a second protective film component on the above-mentioned protective film component. The second protective film component is located below the windproof skirt film and is made of a soft material. Similarly, the soft material can more effectively reduce the wear of the windproof skirt film and extend its service life. It can be made of silica gel material, rubber material, soft PVC, etc.

[0010] Furthermore, there is at least one raised anti-slip component inside the above-mentioned pipe clamp component. The anti-slip component increases the friction with the roof arch bar and can effectively prevent the pipe clamp component from sliding due to external forces (such as wind force, vibration, etc.) during use, ensuring that the pipe clamp component is always firmly fixed on the roof arch bar, thereby guaranteeing the stability and reliability of the entire protective film component.

[0011] A multi-span thin-film greenhouse includes the above-mentioned anti-friction protective film structure, and also includes a gutter, a roof arch bar, a roof rolling film bar, and a windproof skirt film. The roof arch bar is installed on the outside of the gutter. There is a roof rolling film bar above the roof arch bar and is arranged perpendicular to the roof arch bar. The protective film component is installed on the outside of the roof arch bar. The windproof skirt film is laid above the roof arch bar and is located between the roof rolling film bar and the protective film component.

[0012] Furthermore, a first card slot is installed on the above-mentioned gutter, and a second card slot is installed on the roof arch bar. One end of the windproof skirt film is connected to the first card slot, and the other end is connected to the second card slot. Through the connection method of the card slots, the windproof skirt film can be stably laid above the roof arch bar.

[0013] As can be seen from the above technical solution, the present utility model has the following beneficial effects:

[0014] 1. For an anti-friction protective film structure of the present utility model, the protective film component in it adopts a flat plate shape and the surface-to-surface contact method, which can distribute pressure more evenly, effectively reduce the friction between the windproof skirt film and components such as the roof rolling rod and the roof arch rod of the greenhouse, significantly reduce the friction coefficient, thereby greatly extending the service life of the windproof skirt film, and reducing the problems of air leakage and rain leakage in the greenhouse caused by wear and breakage of the windproof skirt film, providing a more stable and suitable growth environment for crops.

[0015] 2. For an anti-friction protective film structure and a multi-span thin-film greenhouse of the present utility model, the pipe clamp component in the protective film component can be conveniently installed on the roof arch rod through a unique notch design, and stable limiting can be achieved, and it is not easy to loosen or slip.

[0016] 3. For an anti-friction protective film structure of the present utility model, the pipe clamp component in the protective film component is made of rigid PVC and has high strength and stability, which can provide reliable support and fixation for the entire protective film component. The protective film component is made of a soft material such as silica gel, rubber or soft PVC, etc., and has good elasticity and wear resistance, which can effectively reduce the wear of the windproof skirt film.

[0017] 4. For an anti-friction protective film structure of the present utility model, the anti-slip component arranged inside the pipe clamp component in the protective film component is made of materials such as rubber, silica gel or rigid plastic, and is designed in shapes such as long strip-shaped protrusions or independent block-shaped protrusions, which can significantly increase the friction force between the pipe clamp component and the roof arch rod, prevent the pipe clamp component from sliding under external forces such as wind force and greenhouse structure vibration, ensure that the entire protective film component always maintains a stable working state, further enhance the protection effect on the windproof skirt film, and reduce the maintenance cost of the greenhouse.

Detailed implementation manners

[0025] The present utility model will be further illustrated below in conjunction with the drawings and specific embodiments.

[0026] Embodiment 1

[0027] As Figure 3 , Figure 4 , Figure 5 shown, in this embodiment, the protective film assembly 5 is composed of a pipe clamp component 51 and a protective film component 52. The pipe clamp component 51 is arranged on the roof arch bar 2, and the protective film component 52 is arranged on the pipe clamp component 51. The protective film component 52 is in a flat plate shape. The pipe clamp component 51 adopts a unique design, being in a circular tubular shape, and having a notch on one side thereof. The spacing of this notch is carefully designed to be smaller than the cross-sectional width of the roof arch bar 2. During installation, the staff only needs to gently open the notch or align the notch with the roof arch bar 2 and then apply a slight pressure, and the pipe clamp component 51 can be smoothly clamped into the roof arch bar 2. This design not only facilitates the installation operation but also ensures that the pipe clamp component 51 is tightly fixed on the roof arch bar 2 and is not easy to loosen or slip. The windproof skirt film 4 and the protective film component 52 adopt a surface contact method, which has significant advantages compared with the traditional direct contact method between the film and the bar (surface-line contact or surface-point contact). The surface-to-surface contact method can distribute the pressure more evenly, reduce hard friction, thereby greatly reducing the friction coefficient, effectively reducing the wear of the windproof skirt film 4. At the same time, this contact method can also more effectively disperse the stress, avoid the problem of local stress concentration, significantly improve the durability of the windproof skirt film 4, and extend its service life.

[0028] In terms of material selection, the protective film component 52 is made of a soft material, such as silicone material, rubber material, soft PVC, etc. These soft materials have good elasticity and wear resistance, and can better adapt to the shape and movement of the windproof skirt film 4, further reducing friction and wear. Or the protective film component 52 is made of rigid PCV. The advantage of rigid PVC is that it is easy to be processed into various shapes and sizes, and the cost is low. The pipe clamp component 51 is made of rigid PVC. The rigid PVC material has high strength and stability, and can provide reliable support and fixation for the protective film assembly 5, ensuring that it always maintains a stable position and function during the use of the greenhouse. The pipe clamp component 51 and the protective film component 52 can be integrally formed or designed as a split type. When the protective film component 52 is made of rigid PVC, a second protective film component 53 can also be provided on it. The second protective film component 53 is made of the above soft material.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, as Figure 6 shown, this embodiment further details the relevant content of the anti-slip component 511. The anti-slip component 511 is arranged inside the pipe clamp component 51, and it can be made of a variety of materials to achieve a good anti-slip effect. For example, rubber material can be selected. Rubber has excellent elasticity and a high friction coefficient, and can closely fit the roof arch bar 2, greatly increasing the friction force between the pipe clamp component 51 and the roof arch bar 2. After the pipe clamp component 51 is installed on the roof arch bar 2, the rubber anti-slip component 511 can effectively prevent the pipe clamp component 51 from sliding under various external forces (such as wind force, vibration of the greenhouse structure, etc.).

[0031] In addition to rubber, silicone is also a commonly used material for the anti-slip component. Silicone has good elasticity and friction properties similar to rubber, and at the same time has higher chemical stability and temperature resistance. In the greenhouse environment, the silicone anti-slip component 511 can adapt to the temperature changes in different seasons and is not easily eroded by chemical substances, thus ensuring its long-term stable anti-slip effect.

[0032] In addition, some rigid plastics (such as polyvinyl chloride PVC) can also be used as the material for the anti-slip component 511. Rigid plastics have a certain hardness and wear resistance. By designing appropriate textures or convex structures on their surfaces, the friction coefficient with the roof arch bar 2 can be increased. Moreover, the plastic material has a relatively low cost and is easy to process and form, and can be customized according to the specific shape and size of the pipe clamp component 51.

[0033] In terms of shape, the anti-slip component 511 can be a strip-shaped protrusion, evenly distributed along the inside of the pipe clip component 51, which can provide friction in multiple directions, ensuring full contact and stable fixation between the pipe clip component 51 and the roof arch bar 2. The design of the strip-shaped protrusion can also disperse the pressure and reduce local wear on the surface of the roof arch bar 2.

[0034] In addition, the anti-slip component 511 can also be an independent block-shaped protrusion, and these block-shaped protrusions can be reasonably arranged inside the pipe clip component 51 according to needs. The advantage of the independent block-shaped protrusion is that the position and density of the protrusions can be adjusted according to the actual situation to achieve the best anti-slip effect. At the same time, this design increases the number of contact points between the pipe clip component 51 and the roof arch bar 2 to a certain extent, further improving the anti-slip performance.

[0035] In short, by setting the anti-slip component 511 inside the pipe clip component 51, whether using materials such as rubber, silicone, or plastic, and the shape design of strip-shaped protrusions or independent block-shaped protrusions, it can significantly improve the installation stability of the pipe clip component 51 on the roof arch bar 2, thus ensuring the reliable operation of the entire protective film component 5, providing more effective protection for the windproof skirt film 4, extending its service life, reducing the greenhouse maintenance cost, and creating a more stable and suitable growth environment for the agricultural planting greenhouse.

[0036] Embodiment 3

[0037] As Figure 1 、 Figure 2 shown, a multi-span film greenhouse includes the above anti-friction protective film structure. It also includes a gutter, roof arch bars, roof rolling film bars, windproof skirt films, and corresponding card slots. The roof arch bars are firmly installed on the outside of the gutter, providing an important support structure for the greenhouse. Above the roof arch bars, there are roof rolling film bars, and the roof rolling film bars are arranged perpendicular to the roof arch bars. This layout is conducive to the film rolling operation and also helps to adjust the environment inside the greenhouse. The protective film component is installed on the outside of the roof arch bars to play a protective role. The windproof skirt film is laid above the roof arch bars and is in the middle position between the roof rolling film bars and the anti-friction protective film structure. Such a design can effectively reduce the friction between the windproof skirt film and other components and extend its service life. To ensure the stable laying of the windproof skirt film, a first card slot is installed on the gutter, and a second card slot is installed on the roof arch bars. One end of the windproof skirt film is connected to the first card slot, and the other end is connected to the second card slot. Through this connection method of the card slots, the windproof skirt film can be firmly fixed above the roof arch bars and will not easily shift or fall off, thus providing stable windproof protection for the greenhouse. In short, the design of this greenhouse, by adopting the anti-friction protective film structure, combined with a reasonable component layout and connection method, effectively improves the stability and reliability of the greenhouse and provides good environmental conditions for the growth of crops.

[0038] The above embodiments are exemplary, and their purpose is to illustrate the technical concept and features of the present utility model, so that those skilled in this field can understand the content of the present utility model and implement it accordingly. However, the protection scope of the present utility model cannot be limited thereby. Any equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
