[0001] The present disclosure relates to the technical field of greenhouses, in particular to a greenhouse film tensioning device and a greenhouse. Background Art

[0002] The surface of the greenhouse is usually covered with a film, and at the edge of the lower end of the film there is a film-fixing rope extending along the length of the film. When installing the film to the greenhouse, multiple iron wires are usually used to tie the film-fixing rope to the bracket of the greenhouse at intervals to stabilize the film. The above method of fixing the film cannot ensure that all positions of the film are tightened after fixing. Utility Model Content

[0003] The purpose of the present disclosure is to provide a greenhouse film tensioning device that does not have the above-mentioned defects.

[0004] To achieve this purpose, the present disclosure provides a greenhouse film tensioning device, comprising:

[0005] A movable rod, wherein a connecting piece is provided on the movable rod, and the connecting piece is configured to be connected to the lower end of the greenhouse film;

[0006] A lower rope body, wherein the lower end of the lower rope body is fixed on the shed, and the upper end of the lower rope body is fixed on the movable rod; and

[0007] An upper rope body, the lower end of which is fixed on the movable rod, and the upper end of which is fixed on the shed;

[0008] Wherein, the lower rope body forms a first winding section on the movable rod and / or the upper rope body forms a second winding section on the movable rod, the winding direction of the first winding section is the same as the winding direction of the second winding section, when the movable rod rotates, the first winding section or the second winding section is unwound, and the movable rod moves downward so that the connecting member pulls the greenhouse film downward.

[0009] According to the greenhouse film tensioning device disclosed in the present invention, the lower end of the greenhouse film can be connected using a connecting piece on the movable rod, and the first winding section or the second winding section can be unwound by rotating the movable rod, thereby achieving the lowering of the movable rod.

[0025] Figure 1 The side view of the greenhouse 1 is shown. The greenhouse 1 can be any type of greenhouse known in the prior art, such as a warm greenhouse, a cold greenhouse, a breeding greenhouse, etc. The greenhouse 1 includes a sunny side and a shady side, and the greenhouse 1 has a sunny slope 11 on the sunny side. The surface of the greenhouse 1 is usually covered with a greenhouse film 3, which is generally a light-transmitting plastic film.

[0026] This embodiment provides a greenhouse film tensioning device 2, which is used to tighten the lower end of the greenhouse film 3 downward so that the greenhouse film 3 fits tightly on the greenhouse 1. Figure 1 As shown, the greenhouse film tensioning device 2 can be installed at the lower part of the sunny slope 11, that is, close to or located at the bottom of the greenhouse 1, so that the lower end of the greenhouse film 3 is close to or located at the bottom of the greenhouse 3.

[0027] Figure 2 The schematic diagram of the greenhouse film tensioning device 2 installed on the greenhouse 1 is shown. Figure 2As shown, the greenhouse film tensioning device 2 includes a movable rod 22, a lower rope body 24 and an upper rope body 25. The movable rod 22 is arranged at a position relatively close to the bottom of the greenhouse 1, and the length direction of the movable rod 22 is parallel to the length direction of the greenhouse 1. The movable rod 22 can not only move up and down, but also rotate around its own axis. The movable rod 22 is provided with a connecting member 23, and the connecting member 23 is configured to be connected to the lower end of the greenhouse film 3. The upper end of the lower rope body 24 is fixedly connected to the movable rod 22, and the lower end of the lower rope body 24 is fixedly connected to the greenhouse 1, for example, fixed to the bracket of the greenhouse 1. In this embodiment, the lower end of the lower rope body 24 is fixed to the fixed rod 21 fixed relatively to the greenhouse 1. The lower end of the upper rope body 25 is fixed to the movable rod 22, and the upper end of the upper rope body 25 is fixed to the greenhouse 1, for example, fixed to the bracket of the greenhouse 1.

[0028] like Figure 2 As shown, in this embodiment, the upper end of the lower rope body 24 is wound around the movable rod 22 for several turns, thereby forming a first winding section 241 on the movable rod 22. Similarly, the lower end of the upper rope body 25 is wound around the movable rod 22 for several turns, thereby forming a second winding section 251 on the movable rod 22, and the winding direction of the first winding section 241 is the same as the winding direction of the second winding section 251, that is, the extension direction of the helical line in the first winding section 241 is consistent with the extension direction of the helical line in the second winding section 251.

[0029] Thus, when the movable rod 22 rotates, for example, Figure 2 When the movable rod 22 shown rotates clockwise in the left view, the first winding section 241 is gradually unwound (i.e., the lower rope body 24 is gradually separated from the movable rod 22), the second winding section 251 is gradually wound (i.e., the upper rope body 25 is gradually wound on the movable rod 22), and the movable rod 22 gradually moves downward, whereby the connecting member 23 moves downward with the movable rod 22, and the connecting member 23 applies a downward pulling force to the greenhouse film 3, so that the greenhouse film 3 is tightened. Conversely, the movable rod 22 can move upward, so that the greenhouse film 3 is loosened.

[0030] It should be noted that, in an embodiment not shown, it is also feasible that one of the lower rope body 24 and the upper rope body 25 forms a winding section on the movable rod 22, for example, the lower rope body 24 forms a first winding section 241 on the movable rod 22, and the lower end of the upper rope body 25 is just connected to the movable rod 22, but no second winding section 251 is formed. For another example, the upper rope body 25 forms a second winding section 251 on the movable rod 22, and the upper end of the lower rope body 24 is just connected to the movable rod 22, but no first winding section 241 is formed.

[0031] That is to say, only one of the first winding section 241 and the second winding section 251 needs to exist, and when one of the first winding section 241 and the second winding section 251 is rolled up, the other of the first winding section 241 and the second winding section 251 is unrolled, thereby realizing the lifting and lowering of the movable rod 22.

[0032] According to the greenhouse film tensioning device 2 disclosed in the present invention, the connecting piece 23 on the movable rod 22 can be used to connect the lower end of the greenhouse film 3, and the first winding section 241 or the second winding section 251 can be unwound by rotating the movable rod 22, thereby realizing the lowering of the movable rod 22. As the movable rod 22 descends, the connecting piece 23 descends accordingly, thereby applying a downward pulling force to the lower end of the greenhouse film 3. By controlling the position of the movable rod 22, the pulling force of the greenhouse film 3 can be effectively controlled, so that the greenhouse film 3 is tightened on the surface of the greenhouse 1.

[0033] There can be one or more movable rods 22, which are arranged at intervals along the length direction of the greenhouse 1. Similarly, there can be one or more fixed rods 21, which are arranged at intervals along the length direction of the greenhouse 1.

[0034] like Figure 2 As shown, in this embodiment, the upper rope body 25 and the lower rope body 24 are actually the same rope, and the middle part of the rope has a fixed point 26, and the fixed point 26 is fixed on the movable rod 22. For example, the rope is wound around a nut (not shown) fixedly connected to the movable rod 22 at the position of the fixed point 26. The fixed point 26 can serve as the upper end of the lower rope body 24, and can also serve as the lower end of the upper rope body 25.

[0035] It should be noted that, in an embodiment not shown, the upper rope body 25 and the lower rope body 24 may also be independent ropes.

[0036] like Figure 2 As shown, in this embodiment, the connecting member 23 includes a hook 231 , and the hook body of the hook 231 is configured to hook on the lower end of the greenhouse film 3 , especially to hook on the film fixing rope 31 at the lower end of the greenhouse film 3 .

[0037] like Figure 2 As shown, further, the connecting member 23 also includes a flexible portion 232, and the hook 231 is arranged at the upper end of the flexible portion 232. With the help of the flexible portion 232, the hook 231 can be moved in various directions, and thus it is easier to hook on the lower end of the greenhouse film 3.

[0038] As an example, Figure 2 The flexible portion 232 is a chain formed by a plurality of interlocking rings.

[0039] like Figure 2As shown, the greenhouse film tensioning device 2 also includes a telescopic component 27, which is connected between the fixed rod 21 and the movable rod 22. When the fixed rod 21 moves up and down, the telescopic component 27 is correspondingly telescoped. With the help of the telescopic component 27, the moving track of the movable rod 22 can be restricted and guided to a certain extent, so that the movable rod 22 can move up and down.

[0040] As an example, the telescopic assembly 27 of this embodiment includes a lower rod body 271 and an upper rod body 272 which are socketed with each other. The lower end of the lower rod body 271 has a cylindrical first sleeve, and the first sleeve is sleeved on the fixed rod 21. Similarly, the upper end of the upper rod body 272 has a cylindrical second sleeve, and the second sleeve can be rotatably sleeved on the movable rod 22. Therefore, when the movable rod 22 rotates, the movable rod 22 can rotate in the second sleeve, and as the movable rod 22 rises and falls, the upper rod body 272 can move relative to the lower rod body 271 to achieve corresponding lifting and lowering movements.

[0041] In order to fix the rotated movable rod 22 at the expected position, a first limiting hole 2721 is provided on the upper rod body 272, and a second limiting hole 221 is provided on the movable rod 22. In this embodiment, there are multiple second limiting holes 221, and the multiple second limiting holes 221 are arranged around the circumferential direction of the movable rod 22, so that after the movable rod 22 is rotated by an angle, one of the second limiting holes 221 can be aligned with the first limiting hole 2721, and then a limiting piece (not shown) can be used to pass through the first limiting hole 2721 and the second limiting hole 221 to keep the movable rod 22 and the upper rod body 272 relatively fixed.

[0042] As an example, the stopper may be a latch.

[0043] In addition, in an embodiment not shown, there may be multiple first limiting holes 2721 , and the multiple first limiting holes 2721 are arranged around the circumferential direction of the second sleeve.

[0044] like Figure 2 As shown, the greenhouse film tensioning device 2 also includes a reducer 28, which is relatively fixed to the greenhouse 1 or the ground, and the power output end of the reducer 28 is connected to the movable rod 22. When the power input end of the reducer 28 inputs power, the reducer 28 drives the movable rod 22 to rotate. The reducer 28 can convert a smaller torque into a larger torque, so that only a smaller torque is required to drive the movable rod 22 to rotate. For example, manually rotating the power input end of the reducer 28 can drive the movable rod 22 to rotate. Of course, in an embodiment not shown, a motor can also be used to drive the reducer 28 to rotate.

[0045] like Figure 3As shown, in order to keep the reducer 28 relatively fixed to the greenhouse 1 or the ground, the greenhouse film tensioning device 2 also includes a support rod 29, the lower end of the support rod 29 abuts against the greenhouse 1 or the ground, and the upper end of the support rod 29 abuts against the reducer 28, so that when the movable rod 22 rotates, the reducer 28 will not rotate.

[0046] like Figure 2 As shown, in this embodiment, the reducer 28 is detachably connected to the movable rod 22. Specifically, the power output end of the reducer 28 and the movable rod 22 are connected via a connecting tube 4, and the cross-sectional shape of the connecting tube 4 is, for example, a polygon, especially a regular hexagon. The power output end of the reducer 28 and the movable rod 22 can also be processed into a regular hexagon accordingly, so that the connecting tube 4 can be sleeved between the power output end of the reducer 28 and the movable rod 22.

[0047] Before installing the above-mentioned greenhouse film tensioning device 2, a ground membrane (not shown) can also be laid on the greenhouse 1. The ground membrane is located on the inner side of the greenhouse film tensioning device 2, the upper end of the ground membrane is fixed to the greenhouse 1, and the lower end of the ground membrane is fixed to the ground. The greenhouse film 3 is located on the outside of the ground membrane, thereby forming a hollow area between the greenhouse film 3 and the ground membrane, further improving the thermal insulation effect of the greenhouse 1.

[0048] The above is a description of the embodiments of the present disclosure. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present disclosure. Various modifications to these embodiments will be apparent to professionals and technicians in the field. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novelties disclosed herein.
