[0029] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention.

[0031] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the sake of convenience in explanation, the cross-sectional views showing the device structure are locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0032] Embodiment 1 Referring to Figure 1 - Figure 8 , which is the first embodiment of the present invention. This embodiment provides a new type of prefabricated solar greenhouse for vegetable cultivation, including a greenhouse wall 1. The greenhouse wall 1 is connected to an outer arch frame 11, and an outer transparent film is attached to the outer side of the outer arch frame 11. The greenhouse wall 1 is connected to an inner arch frame 12. The rod bodies of the inner arch frame 12 and the outer arch frame 11 are distributed in the same manner. There are two groups of guide rails 13 in the area between the inner arch frame 12 and the outer arch frame 11. The guide rails 13 are located in the side area inside the greenhouse. Two sliders 14 are slidably connected to the two groups of guide rails 13. The two sliders 14 are jointly connected to a winding mechanism 15. An inner insulation film is wound around the winding mechanism 15, and one side of the inner insulation film is connected to the top end of the inner arch frame 12. The winding mechanism 15 unwinds the inner insulation film outside the inner arch frame 12. A self-sealing strip structure is provided on the contact surface between the edge rod body 121 of the inner arch frame 12 and the unwound inner insulation film. The winding mechanism winds the inner insulation film on the top side between the outer arch frame 11 and the inner arch frame 12. When the sun sets and the temperature gradually decreases, the transmission mechanism drives the slider 14 to move along the guide rail 13, and the originally wound inner insulation film is gradually unwound through the winding mechanism 15, so that the inner insulation film is gradually laid outside the inner arch frame 12.

[0033] Specifically, the inner arch frame 12 and the inner insulation film are connected through a self-sealing strip structure, so as to form a double-layer insulation structure between the inner arch frame 12 and the outer arch frame 11. The four walls of the inner arch frame 12 are connected to the wall of the greenhouse. When the inner arch frame 12 is hermetically covered, the internal environment of the greenhouse is also isolated by the covering layer of the inner arch frame 12.

[0034] Furthermore, one end of the slider 14 is connected with a transmission mechanism, and the transmission mechanism is in transmission connection with the winding mechanism 15, and drives the slider 14 and the winding mechanism 15 through the transmission mechanism to perform the winding and unwinding actions of the inner thermal insulation film on the outer side of the inner arch frame 12.

[0035] Furthermore, a side plate 2 is installed on one side of the slider 14. A cross plate 21 is connected to the outer wall of the side plate 2. A spring member 22 is provided on the bottom side of the cross plate 21. The bottom end of the spring member 22 is installed with a pressing plate 23. The spring member 22 applies a pressing force to the pressing plate 23. The pressing plate 23 is located on the outer side of the inner thermal insulation film, presses the just-unwound inner thermal insulation film on the outer side of the inner arch frame 12, so that the self-sealing strips of the inner thermal insulation film and the edge rod body 121 are pressed to complete self-sealing. When the inner thermal insulation film is completely unwound, the pressing plate 23 is located on one side of the bottom rod 122, so that the terminal of the bottom-side inner thermal insulation film is pressed and sealed.

[0036] Furthermore, an air delivery channel 3 is placed in the bottom area between the outer arch frame 11 and the inner arch frame 12. One end of the air delivery channel 3 extends outside the greenhouse wall 1, and a carbon dioxide gas cylinder is installed at the extended end of the air delivery channel 3. An air delivery valve body 31 is provided on the air delivery channel 3, and the air delivery valve body 31 is embedded inside the greenhouse wall 1.

[0037] Furthermore, a contact wheel 311 is connected to the inner wall of the air delivery valve body 31 through a pin shaft, and the contact wheel 311 is exposed in the heat insulation layer between the outer arch frame 11 and the inner arch frame 12. A return strip 312 is embedded in the inner wall of the air delivery valve body 31. One end of the return strip 312 is in transmission engagement with the contact wheel 311 through a rack structure. The other end of the return strip 312 is connected with a sealing plug 313. One side of the sealing plug 313 is the flow area of the air delivery channel 3. The movement of the sealing plug 313 seals the flow area. A resilient member 32 is provided on one side inner wall of the air delivery valve body 31 where the inner arch frame 12 is located. An extension rod 33 is installed on the outer wall of the return strip 312, and the extension rod 33 extends to one side of the resilient member 32.

[0038] Furthermore, the resilient member 32 includes a cavity 321 opened on the outer side of the inner arch frame 12. The port of the cavity 321 is opened towards the outside. A sealing plate 322 is provided inside the cavity 321. A lever member 323 is provided on the top side of the sealing plate 322. One end of the lever member 323 is located on the top side of the extension rod 33, and the support point of the lever member 323 is close to one side of the extension rod 33, so that when the sealing plate 322 is upwardly stressed, the force at the other end of the lever member 323 is greater.

[0039] Further, the bottom side of the slider 14 is connected to the contact block 141 through an elastic member. When the slider 14 unwinds the inner insulation film, the right-angle side of the contact block 141 touches the contact wheel 311 to rotate. When the slider 14 is restored, the contact between the inclined surface of the contact block 141 and the contact wheel 311 causes the contact block 141 to retract into the slider 14.

[0040] Working principle: During the day, its winding mechanism 15 winds the inner insulation film on the top side between the outer arch frame 11 and the inner arch frame 12. When the sun sets and the temperature gradually decreases, the transmission mechanism drives the slider 14 to move along the guide rail 13, and the originally wound inner insulation film is gradually unwound through the winding mechanism 15, so that the inner insulation film is gradually laid on the outer side of the inner arch frame 12. During the movement, the pressing plate 23 connected to the tail end of the slider 14 is touched by the spring member 22 on the cross plate 21, so that the just-laid inner insulation film is touched by the pressing plate 23, thereby enabling the self-sealing strip structure between the inner insulation film and the edge rod 121 to fit, and then the inner arch frame 12 is gradually sealed and covered by the inner insulation film. There is no self-sealing strip structure on the contact surface between the inner insulation film and the bottom rod 122. When the winding mechanism 15 completely unwinds, the pressing plate 23 is located on one side of the bottom rod 122, so that the contact surface between the inner insulation film and the bottom rod 122 is pressed and sealed by the pressing plate 23. At this time, a closed double-layer insulation structure is formed between the inner arch frame 12 and the outer arch frame 11, effectively improving the insulation effect of the greenhouse. When the slider 14 moves to the terminal (i.e., when the unwinding of the inner insulation film ends), the straight edge of the contact block 141 on the bottom side of the slider 14 touches the contact wheel 311 and causes it to rotate. The rotation of the contact wheel 311 drives the moving of the loop strip 312. The loop strip 312 protrudes outwards from the outside of the air supply valve body 31, causing the sealing plug 313 at the other end of the loop strip 312 to move, so that the flow cavity blocked by the sealing plug 313 is opened. At this time, the air supply channel 3 gradually conveys carbon dioxide between the inner arch frame 12 and the outer arch frame 11 until the air pressure between the inner arch frame 12 and the outer arch frame 11 increases, causing the connected cavity 321 to drive the sealing plate 322 to move due to the increased air pressure. The sealing plate 322 receives a slight thrust, and the thrust of the sealing plate 322 is amplified through the lever member 323, so that the lever member 323 pushes the extension rod 33, causing the extension rod 33 to move and restore the loop strip 312, thereby closing the carbon dioxide inflation state. At this time, the state between the inner arch frame 12 and the outer arch frame 11 is a high-carbon dioxide state. And carbon dioxide is a greenhouse gas. When the temperature decreases and the sun has not completely set, it can transmit the short-wave radiation of the sun and at the same time absorb the long-wave radiation emitted by the ground, effectively warming up when the sun has not completely set. And the heat transfer efficiency of carbon dioxide is lower than that of air, effectively reducing the heat transfer amount of this interlayer and improving the insulation effect at night. When it gets dawn the next day, at this time the winding mechanism 15 rewinds the inner insulation film to the top side of the inner arch frame 12, and the originally used carbon dioxide for insulation can naturally fill into the greenhouse environment, making the high-carbon dioxide environment more conducive to the photosynthesis of vegetables in the greenhouse and beneficial to the growth of vegetables.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
