Abstract
Description
Technical Field
[0001] This utility model relates to the field of solar greenhouse technology, specifically a buffer device for the ventilation opening of a solar greenhouse. Background Technology
[0002] A solar greenhouse, also known as an energy-saving solar greenhouse or a warm shed, consists of two side walls, a rear wall, a supporting frame, and covering materials. It is a type of greenhouse that does not require heating inside. Instead, it absorbs and stores solar energy through the rear wall to maintain a certain temperature level inside, thus meeting the needs of vegetable crops for growth.
[0003] The existing greenhouse ventilation openings have poor buffering effect. The crops cultivated below the ventilation openings, as well as the row of crops cultivated east-west corresponding to the ventilation openings, are prone to viral diseases and other physiological diseases due to the invasion of cold winds, which reduces yield and affects quality.
[0004] Based on this, a buffer device for the ventilation opening of a solar greenhouse is provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this invention is to provide a buffer device for the ventilation opening of a solar greenhouse to solve the problem of poor buffering effect at the ventilation opening in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A vent buffer device for a solar greenhouse includes land, a greenhouse steel frame, and four concrete foundation blocks. The greenhouse steel frame is fixedly installed on top of the land, and the four concrete foundation blocks are fixedly installed on top of the land, with the four concrete foundation blocks located at both ends of the greenhouse steel frame. A greenhouse covering film is laid on the outside of the greenhouse steel frame.
[0008] An adjustment mechanism is installed on the top of the concrete foundation block, and two limiting rods are fixedly installed on one side of the top of the concrete foundation block. A winding mechanism is installed on the outside of the two limiting rods.
[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

A circular arc groove is provided on one side of the sector plate, and an installation frame is rotatably installed on the other side of the sector plate. A membrane is installed on the outside of the installation frame, and a limit block is slidably installed inside the circular arc groove, with one end of the limit block fixedly installed to the installation frame.
[0011] In one alternative: a second buckle is rotatably installed on one side of the fan-shaped plate, and a first buckle is rotatably installed on one side of the greenhouse steel frame, both the first and second buckles being adapted to the limiting block.
[0012] In one alternative: the winding mechanism includes a protective shell, which is slidably mounted between two limiting rods. A first gear and a second gear are rotatably mounted inside the protective shell, and the first gear and the second gear mesh with each other. A rotating assembly is provided on one side of the protective shell.
[0013] In one alternative: the rotating assembly includes a cover plate, which is fixedly mounted on one side of the protective housing by screws, and one end of the first gear passes through the cover plate and is connected to a crank handle.
[0014] In one alternative: one end of the second gear passes through the protective shell and is connected to a winding assembly, and both outer sides of the protective shell are threaded with knobs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model adjusts the angle of the surrounding film through an adjustment mechanism. The wind first contacts the surrounding film, and the surrounding film guides the wind, causing the external air to move upward. This avoids the external cold air from directly contacting the plants on both sides. Due to the invasion of cold wind, viral diseases and other physiological diseases are prone to occur, reducing yield and affecting quality. The buffer device can effectively reduce the adverse effects of cold wind on crops and seedlings cultivated in solar greenhouses, and improve the yield, quality and efficiency of crop cultivation and melon and vegetable seedlings.
[0019] 2. This utility model can roll up both sides of the greenhouse covering film through the winding mechanism, so that air can circulate through both sides, which can play the roles of dehumidification, cooling and ventilation. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-4 As shown, a vent buffer device for a solar greenhouse includes a land 1, a greenhouse steel frame 2 and four concrete foundation blocks 4. The greenhouse steel frame 2 is fixedly installed on the top of the land 1, and the four concrete foundation blocks 4 are fixedly installed on the top of the land 1, with the four concrete foundation blocks 4 located at both ends of the greenhouse steel frame 2. A greenhouse covering film 3 is laid on the outside of the greenhouse steel frame 2.
[0027] An adjustment mechanism 5 is installed on the top of the concrete foundation block 4, and two limiting rods 6 are fixedly installed on one side of the top of the concrete foundation block 4. A winding mechanism 8 is installed on the outside of the two limiting rods 6.
[0028] In this embodiment, the greenhouse steel frame 2 and the greenhouse covering film 3 form a solar greenhouse. The two sides of the greenhouse covering film 3 can be rolled up by the rolling mechanism 8, allowing air to circulate through both sides, which plays a role in dehumidification, cooling and ventilation. The angle of the surrounding film 54 can be adjusted by the adjusting mechanism 5. The wind first contacts the surrounding film 54, and the surrounding film 54 guides the wind, causing the external air to move upward, avoiding direct contact between the external cold air and the plants on both sides. Due to the invasion of cold wind, viral diseases and other physiological diseases are prone to occur, reducing yield and affecting quality. The buffer device can effectively reduce the adverse effects of cold wind on crops and seedlings cultivated in the solar greenhouse, and improve the yield, quality and efficiency of crop cultivation and melon and vegetable seedlings.
[0029] In one embodiment, such as Figure 1 and Figure 3As shown, the adjustment mechanism 5 includes a sector plate 51, which is fixedly installed on the top of the concrete foundation block 4. A circular arc groove 52 is formed on one side of the sector plate 51, and a mounting frame 53 is rotatably installed on the other side of the sector plate 51. A surrounding membrane 54 is installed on the outside of the mounting frame 53. A limiting block 55 is slidably installed inside the circular arc groove 52, and one end of the limiting block 55 is fixedly installed to the mounting frame 53. A second buckle 57 is rotatably installed on one side of the sector plate 51, and a first buckle 56 is rotatably installed on one side of the greenhouse steel frame 2. Both buckle 56 and second buckle 57 are adapted to limit block 55. When ventilation is required in the greenhouse, first release the first buckle 56 from the limit block 55, rotate the mounting frame 53 along the length of the arc groove 52, and then use the second buckle 57 to lock the limit block 55. At this time, the angle of the surrounding film 54 changes, and the external cold air moves upward through the guiding effect of the surrounding film 54, avoiding direct contact between the plants on both sides and the cold air. This can effectively reduce the adverse effects of cold wind on crops and seedlings cultivated in the greenhouse, and improve the yield, quality and efficiency of crop cultivation and melon and vegetable seedlings.
[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the winding mechanism 8 includes a protective shell 81, which is slidably mounted between two limiting rods 6. A first gear 82 and a second gear 83 are rotatably mounted inside the protective shell 81, and the first gear 82 and the second gear 83 mesh with each other. A rotating assembly is provided on one side of the protective shell 81, and the rotating assembly includes a cover plate 84, which is fixedly mounted on one side of the protective shell 81 by screws. One end of the first gear 82 passes through the cover plate 84 and is connected to a crank handle 85. One end of the second gear 83 passes through the protective shell 81 and is connected to the winding assembly. Knobs 87 are threaded onto both sides of the outer surface of the protective shell 81. The winding assembly includes a winding rod 86, one end of which is connected to one end of the second gear 83. One end of the greenhouse covering film 3 is wound around the outside of the winding rod 86. The other end of the winding rod 86 is rotatably mounted with a sliding plate 7, and the sliding plate 7 is slidably mounted with the limiting rod 6. When the weather is hot, the temperature inside the greenhouse is too high and ventilation is required to cool it down. At this time, the crank handle 85 is turned, which drives the first gear 82 to rotate. The first gear 82 drives the second gear 83 to rotate, and the second gear 83 drives the winding rod 86 to rotate. The winding rod 86 rolls up the greenhouse covering film 3. During this process, the protective shell 81 moves upward along the length of the limiting rod 6. After moving to the designated height, the knob 87 is locked to improve the efficiency of both sides of the greenhouse, quickly reduce the temperature, and avoid the temperature from being too high and affecting plant growth. When ventilation is not required, the knob 87 is loosened, the crank handle 85 is turned in the opposite direction, and the winding rod 86 releases the greenhouse covering film 3. At the same time, the protective shell 81 moves downward. When the height of the winding rod 86 is lower than the top of the surrounding film 54, the rotation stops.
[0031] The above embodiment discloses a vent buffer device for a solar greenhouse. The greenhouse steel frame 2 and the greenhouse covering film 3 form a solar greenhouse. When ventilation is required, the first buckle 56 is released from the locking block 55, the mounting frame 53 is rotated along the length of the arc groove 52, and then the second buckle 57 is used to lock the locking block 55. At this time, the angle of the surrounding film 54 changes, and the external cold air moves upward through the guiding effect of the surrounding film 54, avoiding direct contact between the plants on both sides and the cold air. This can effectively reduce the adverse effects of cold air on crops and seedlings cultivated in the solar greenhouse, and improve the yield, quality and efficiency of crop cultivation and melon and vegetable seedlings.
[0032] When the weather is hot, the temperature inside the greenhouse becomes too high, requiring ventilation to cool it down. At this time, turn the crank handle 85, which drives the first gear 82 to rotate. The first gear 82 drives the second gear 83 to rotate, and the second gear 83 drives the winding rod 86 to rotate. The winding rod 86 rolls up the greenhouse covering film 3. During this process, the protective shell 81 moves upward along the length of the limit rod 6. After moving to the designated height, the knob 87 is locked to improve the efficiency of both sides of the greenhouse, quickly reduce the temperature, and prevent the temperature from being too high and affecting plant growth. When ventilation is not needed, loosen the knob 87 and turn the crank handle 85 in the opposite direction. The winding rod 86 releases the greenhouse covering film 3, and at the same time, the protective shell 81 moves downward. When the height of the winding rod 86 is lower than the top of the surrounding film 54, the rotation stops.
[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
