Description

Technical Field

[0002] Solar greenhouses are generally equipped with a roller shutter mechanism. When the outside temperature is low at night, the roller shutter can cover the surface of the greenhouse, effectively blocking the heat inside the greenhouse from dissipating outward, so that the temperature inside the greenhouse is maintained within a range suitable for crop growth. The roller shutter mechanism is located in the outer environment of the greenhouse, making the covering film of the roller shutter mechanism susceptible to environmental influences.

[0003] The China Patent Network has published a publication number: CN112470786A, which discloses a double-layer heat-insulating solar greenhouse. An outer shed and an inner shed are arranged between the west wall and the east wall.

[0036] Example 1

[0037] Reference Figure 1 - Figure 8 , which is the first embodiment of the present invention, provides a new type of assembled solar energy greenhouse for vegetable cultivation, including a greenhouse wall 1, the greenhouse wall 1 is connected to an outer arch frame 11, and the outer side of the outer arch frame 11 is attached with an outer transparent film; the greenhouse wall 1 is connected to an inner arch frame 12, and the rod distribution of the inner arch frame 12 is consistent with that of the outer arch frame 11. Two sets of guide rails 13 are provided 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 of ​​the greenhouse. Slide blocks 14 are slidably connected to the two sets of guide rails 13. The two sets of slide blocks 14 are commonly connected to a set of winding mechanism 15. The winding mechanism 15 An inner thermal insulation film is wrapped on it, and one side of the inner thermal insulation film is connected to the top of the inner arch frame 12. The winding mechanism 15 unwinds the inner thermal insulation film on the outside of the inner arch frame 12. The edge rod 121 of the inner arch frame 12 and the contact surface with the inner thermal insulation film after unwinding are provided with a self-sealing strip structure. The winding mechanism rolls up the inner thermal 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 rolled inner thermal insulation film is gradually unwound through the winding mechanism 15, so that the inner thermal insulation film is gradually laid on the outside of the inner arch frame 12.

[0038] Specifically, the inner arch frame 12 and the inner insulation film are connected by a self-sealing strip structure, so that a double-layer insulation structure is formed 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 walls of the greenhouse. When the inner arch frame 12 is sealed and covered, the internal environment of the greenhouse is also isolated by the covering layer of the inner arch frame 12.

[0039] Furthermore, one end of the slider 14 is connected to a transmission mechanism, and the transmission mechanism is connected to the winding mechanism 15 , and the transmission mechanism drives the slider 14 and the winding mechanism 15 to perform winding and unwinding of the inner insulation film on the outside of the inner arch 12 .

[0040] Furthermore, a side plate 2 is installed on one side of the slider 14, and the outer wall of the side plate 2 is connected to a horizontal plate 21. A spring member 22 is provided on the bottom side of the horizontal plate 21, and a pressing plate 23 is installed on the bottom end of the spring member 22. The spring member 22 applies tight pressure to the pressing plate 23. The pressing plate 23 is located on the outside of the inner thermal insulation film, pressing the newly unwound inner thermal insulation film against the outside of the inner arch 12, so that the self-sealing strip of the inner thermal insulation film and the edge rod 121 are pressed to complete self-sealing. When the inner thermal insulation film is completely unwound, the pressing plate 23 is located on the side of the bottom rod 122, so that the terminal of the bottom inner thermal insulation film is pressed and sealed.

[0041] Furthermore, a gas supply channel 3 is placed in the bottom area between the outer arch frame 11 and the inner arch frame 12, one end of the gas supply channel 3 extends to the outside of the greenhouse wall 1, and a carbon dioxide gas tank is installed at the extended end of the gas supply channel 3. A gas supply valve body 31 is provided on the gas supply channel 3, and the gas supply valve body 31 is embedded in the interior of the greenhouse wall 1.

[0042] Furthermore, the inner wall of the gas valve body 31 is connected to a contact wheel 311 through a pin shaft, and the contact wheel 311 is exposed in the thermal insulation interlayer of the outer arch frame 11 and the inner arch frame 12. A circular strip 312 is embedded in the inner wall of the gas valve body 31. One end of the circular strip 312 is engaged with the contact wheel 311 through a rack structure. The other end of the circular strip 312 is connected to a sealing plug 313. One side of the sealing plug 313 is the flow area of ​​the gas transmission channel 3. The movement of the sealing plug 313 seals the flow area. A rebound part 32 is provided on the inner wall of the inner arch frame 12 on one side of the gas valve body 31. An extension rod 33 is installed on the outer wall of the circular strip 312. The extension rod 33 extends to one side of the rebound part 32.

[0043] Furthermore, the rebound member 32 includes a cavity 321 opened on the outside of the inner arch frame 12, the end of the cavity 321 is opened toward 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, and 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 subjected to upward force, the force of the other end of the lever member 323 is greater.

[0044] Furthermore, 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 thermal insulation film, the right-angled edge of the contact block 141 triggers the contact wheel 311 to rotate. When the slider 14 recovers, 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 interior of the slider 14.

[0045] Working principle: During the day, the reeling mechanism 15 reels the inner thermal insulation film on the top side between the outer arch 11 and the inner arch 12. When the sun sets and the temperature gradually drops, the transmission mechanism drives the slider 14 to move along the guide rail 13, and the reeling mechanism 15 gradually unwinds the originally rolled inner thermal insulation film, so that the inner thermal insulation film is gradually laid on the outside of the inner arch 12. During the movement, the pressing plate 23 connected to the tail end of the slider 14 is pressed by the spring part 22 on the cross plate 21, so that the newly laid inner thermal insulation film is pressed by the pressing plate 23, thereby making the self-sealing strip structure between the inner thermal insulation film and the edge rod body 121 fit together, thereby making the inner arch 12 gradually close. It is sealed and covered by the inner thermal insulation film, and the contact surface between the inner thermal insulation film and the bottom rod 122 has no self-sealing strip structure. When the winding mechanism 15 is completely unwound, its pressing plate 23 is located on one side of the bottom rod 122, so that the contact surface between the inner thermal insulation film and the bottom rod 122 is pressed and sealed by the pressing plate 23. At this time, a closed double-layer thermal insulation structure is formed between the inner arch frame 12 and the outer arch frame 11, which effectively improves the thermal insulation effect of the greenhouse. When the slider 14 moves to the terminal end (that is, when the inner thermal insulation film is unwound), the straight edge of the contact block 141 on the bottom side of the slider 14 triggers the touch wheel 311 to rotate, and the rotation of the touch wheel 311 drives the paper-shaped strip 312 to move, and the paper-shaped strip 312 protrudes toward the outside of the gas valve body 31. , so that the sealing plug 313 at the other end of the paper-shaped strip 312 moves, so that the flow cavity blocked by the sealing plug 313 is opened. At this time, the gas transmission channel 3 gradually transports carbon dioxide to 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, so that the connected cavity 321 drives the sealing plate 322 to move due to the increased air pressure. The sealing plate 322 is gently pushed, and the thrust of the sealing plate 322 is amplified by the lever member 323, so that the lever member 323 pushes the extension rod 33, so that the extension rod 33 moves to restore the paper-shaped strip 312, thereby closing the inflated state of carbon dioxide. At this time, the inner arch frame 12 and the outer arch frame 11 is in a high carbon dioxide state, and carbon dioxide is a greenhouse gas. When the temperature drops and the sun has not completely set, it can pass through the sun's short-wave radiation and absorb the long-wave radiation emitted by the ground, so that it can effectively warm up before the sun has completely set. The heat transfer efficiency of carbon dioxide is lower than that of air, which effectively reduces the heat transfer amount of the insulation layer and improves the insulation effect at night. When it gets light the next day, the winding mechanism 15 rewinds the inner insulation film to the top side of the inner arch frame 12, and the carbon dioxide originally used for insulation can be naturally filled into the greenhouse environment, making the high carbon dioxide environment more conducive to the photosynthesis of vegetables in the greenhouse environment and conducive to the growth of vegetables.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
