Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, in particular to an inner film device installed in a single steel frame greenhouse. Background Art

[0002] Steel frame greenhouses are mainly composed of steel frames and insulation film. The steel frame structure has strong stability and load-bearing capacity, which can withstand adverse weather conditions and ensure the stability of the greenhouse's internal environment. As an important facility in agricultural production, single steel frame greenhouses provide a good growth environment for crops.

[0003] During winter production, in order to further improve the thermal insulation performance of single-frame steel frame greenhouses, farmers and agricultural technicians often need to install an inner film inside the single-frame steel frame greenhouse to form a double-layer greenhouse film structure. However, the existing installation method is often to install an inner steel frame greenhouse and lay greenhouse film on the inner greenhouse to form a double-layer greenhouse film structure. On the one hand, this method has low installation efficiency and high cost, which is not conducive to promotion and use among small farmers. On the other hand, there is a gap between the outer and inner greenhouses, which makes the inner greenhouse space smaller, reducing the planting area and the space for crop growth. Therefore, there is an urgent need for a single-frame steel frame greenhouse to install an inner film device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0008] As an improved technical solution, the gap between the thermal insulation inner film and the greenhouse frame is the same.

[0009] As an improved technical solution, the end portion of the thermal insulation inner membrane is buried underground.

[0010] As an improved technical solution, a plurality of the connecting ropes are distributed on the arched steel frame at equal intervals.

[0011] As an improved technical solution, one end of the connecting rope is provided with a Prussian knot, and the Prussian knot is mounted on the arched steel frame. The other end of the connecting rope is provided with a slipknot, and the slipknot is mounted on the support.

[0025] like Figure 1-2 As shown together, the present embodiment provides a device for adding an inner membrane to a single-body steel frame greenhouse. The device for adding an inner membrane to a single-body steel frame greenhouse includes a greenhouse frame 1. The greenhouse frame 1 is composed of a plurality of arched steel frames 101 arranged at equal intervals. It also includes an insulating inner membrane 2 arranged in the greenhouse frame 1. A plurality of connecting ropes 3 are connected to the arched steel frames 101. One end of the connecting rope 3 passes through a through hole opened on the insulating inner membrane 2 and extends downward. One end of the connecting rope 3 is fixedly connected to a support member 4, which is used to provide support for the insulating inner membrane 2.

[0026] In the above technical solution, by connecting multiple connecting ropes 3 on each arched steel frame 101, a through hole is opened at the position of the thermal insulation inner membrane 2 corresponding to the connecting rope 3 and the connecting rope 3 is passed through, and then the support member 4 is connected to one end of the connecting rope 3. The support member 4 is located on the lower side of the thermal insulation inner membrane 2 to provide support for it.

[0027] The gap between the thermal insulation inner film 2 and the greenhouse frame 1 is the same. During the installation process, the distance between the thermal insulation inner film 2 and the greenhouse frame 1 can be adjusted by adjusting the length of the connecting rope 3 so that the distance between each connection point remains the same, thereby effectively increasing the planting space inside the thermal insulation inner film 2.

[0028] The end of the thermal insulation inner membrane 2 is buried underground and fixed to the ground, so that the connecting rope 3 located on the side of the arched steel frame 1 can provide pulling limit for the thermal insulation inner membrane 2, so that the thermal insulation inner membrane 2 can be effectively unfolded.

[0029] A plurality of connecting ropes 3 are distributed on the arched steel frame 101 at equal intervals. The equal interval distribution of the connecting ropes 3 can further ensure the internal space after the thermal insulation inner membrane 2 is unfolded.

[0030] One end of the connecting rope 3 is provided with a Prussian knot 301, which is sleeved on the arched steel frame 101, and the other end of the connecting rope 3 is provided with a slipknot 302, which is sleeved on the support member 4.

[0031] 1-2 support members 4 can be connected to the connecting rope 3. The lower support member 4 is used to support the thermal insulation inner membrane 2. The upper support member 4 can limit the thermal insulation inner membrane 2 to prevent the thermal insulation inner membrane 2 from loosening.

[0032] In the above technical solution, the suspension length of the connecting rope 3 can be adjusted through the Prussian knot 301, thereby adjusting the position of the thermal insulation inner membrane 2. The support frame 4 is connected to the slipknot 302, which is convenient for disassembly when not in use, thereby achieving multiple reuse.

[0033] The support member 4 is an empty plastic bottle, and the connecting rope 3 can be a nylon rope. The support member 4 can be obtained by recycling plastics, and can be used together with the connecting rope 3 to effectively reduce the cost of use.

[0034] When in use, multiple connecting ropes 3 are connected at equal intervals on each arched steel frame 101, so that a through hole is opened at the position corresponding to the connecting rope 3 in the thermal insulation inner membrane 2 and the connecting rope 3 is passed through. After the support member 4 is connected to one end of the connecting rope 3, the support member 4 is located on the lower side of the thermal insulation inner membrane 2 to provide support for it.

[0035] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
