[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7This utility model provides a technical solution: a greenhouse insulation structure, including an inner frame 1, a top frame 2, an inner membrane 3, a top membrane 4, a wind-resistant column 5, an outer membrane 6, a support plate 7, a first drive shaft 8, a first motor 9, a second drive shaft 10, a second motor 11, a steering shaft 12, an insulation blanket 13, and a traction rope 14.

[0030] The inner frame 1 consists of multiple parallel n-shaped rods, which are fixedly connected as a whole by the same reinforcing rod. An inner membrane 3 is fixedly connected to the outer surface of the inner frame 1. A top frame 2 is fixedly connected to the upper end of the inner frame 1. The top frame 2 consists of multiple parallel arched structures, and a top membrane 4 is fixedly connected to its outer surface. The inner frame 1, top frame 2, inner membrane 3, and top membrane 4 constitute a greenhouse unit. One side surface of the greenhouse unit has a double-layer structure, which enhances the lateral stability of the greenhouse unit through wind-resistant columns 5 and an outer membrane 6. For wind resistance, two greenhouse units are symmetrically arranged, and the double-layer structure on the side surface of the two greenhouse units is also symmetrically arranged. The double-layer structure includes wind-resistant columns 5. The lower part of the wind-resistant column 5 is round rod-shaped, and the upper part of the wind-resistant column 5 is arc-shaped. The upper and lower parts of the wind-resistant column 5 are integrated. The upper end of the wind-resistant column 5 is fixedly connected to the top frame 2. Multiple wind-resistant columns 5 are arranged in parallel, and the parallel wind-resistant columns 5 are fixedly connected to the same reinforcing rod. An outer membrane 6 is fixedly connected to the outer surface of the wind-resistant column 5. The outer membrane 6 is arranged in parallel with the side surface of the inner membrane 3.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this device, the inner frame 1 and the top frame 2 provide the main support for the greenhouse. The inner film 3 and the top film 4, which support the outer surface, form a greenhouse unit. Crops are planted in the greenhouse unit. A wind-resistant column 5 is fixedly connected to one side of the top frame 2. An outer film 6 is provided on the outer surface of the wind-resistant column 5. The parallel outer film 6 and the inner film 3 form a double-layer structure on the side facade of the greenhouse unit. Compared with the traditional single-layer film-covered greenhouse, it can better maintain the temperature inside the greenhouse, increase the heat preservation performance of the greenhouse unit, and strengthen the wind resistance performance of the side facade of the greenhouse unit.

[0032] The inner membrane 3 has a vertical insulation structure inside, which further insulates the greenhouse through the insulation blanket 13. The vertical insulation structure includes support plates 7, which are fixedly connected to the outer surface of the inner frame 1. Two support plates 7 are symmetrically arranged, forming a group. There are three groups of support plates 7. One group of support plates 7 is located at the bottom of one side of the inner frame 1, the second group is located at the top of one side of the inner frame 1, and the third group is located at the top of the other side of the inner frame 1. The three groups of support plates 7 are arranged in a right-angled triangle. A first drive shaft 8 is rotatably connected between the first group of support plates 7. 8 is fixedly connected to the output end of the first motor 9. The first motor 9 is fixedly installed on the surface of the first set of support plates 7. A steering shaft 12 is fixedly connected between the support plates 7. A second drive shaft 10 is rotatably connected between the third set of support plates 7. The second drive shaft 10 is fixedly connected to the output end of the second motor 11. The second motor 11 is fixedly installed on the surface of the third set of support plates 7. An insulation blanket 13 is installed inside the inner frame 1. Traction ropes 14 are connected to both sides of the insulation blanket 13. One traction rope 14 passes over the steering shaft 12 and is fixedly connected to the outer surface of the first drive shaft 8. The other traction rope 14 is fixedly connected to the surface of the second drive shaft 10.

[0033] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, when it is necessary to unfold the insulation blanket 13 to further insulate the greenhouse, the first motor 9 is started. The first motor 9 drives the first drive shaft 8 to rotate. The rotation of the first drive shaft 8 causes the traction rope 14 on the surface to wind around. The traction rope 14 causes one side of the insulation blanket 13 to pass through the steering shaft 12 and approach the first drive shaft 8. At this time, the traction rope 14 on the other side of the insulation blanket 13 is connected to the surface of the second drive shaft 10. Under the action of the traction ropes 14 on both sides, the insulation blanket 13 remains stationary on the side of the greenhouse, using the insulation blanket 13 to increase the insulation performance of the greenhouse. When it is necessary to retract the insulation blanket 13, the second motor 11 is started. The second motor 11 drives the second drive shaft 10 to rotate. The second drive shaft 10 causes the traction rope 14 on one side of the insulation blanket 13 to wind around. Under the traction action of the traction rope 14, the insulation blanket 13 moves in the opposite direction, so that the insulation blanket 13 is stationary at the top of the greenhouse.

[0034] Working principle: When using this type of greenhouse insulation structure, the wind-resistant columns 5 and the outer film 6 form a double-layer structure on the side facade of the greenhouse unit, increasing the insulation performance of the greenhouse unit. The double-layer structure also enhances the wind resistance of the side facade of the greenhouse unit. When insulation operation is required, the first motor 9 is started. The first motor 9 drives the first drive shaft 8 to rotate. The rotating first drive shaft 8 drives the traction rope 14 on one side of the insulation blanket 13 to move, thereby realizing the unfolding of the insulation blanket 13 inside the greenhouse. The multi-layer structure formed by the outer film 6, the inner film 3 and the insulation blanket 13 can further increase the insulation performance of the greenhouse and increase the overall practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
