Detailed Implementation

[0053] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0054] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings.

[0056] Preferred, such as Figure 1 As shown, in this embodiment, the main structure of the greenhouse 1 is an improvement on the existing single-slope solar greenhouse. It is composed of a stainless steel frame and a plastic film 12. The plastic film 12 is covered on the outside of the stainless steel frame. Its roof structure is the same as that of the existing single-slope solar greenhouse. The difference is that the insulation wall structure of the existing single-slope solar greenhouse is omitted and replaced by a stainless steel frame and plastic film 12 to reduce the overall construction cost and make it more suitable for small and medium-sized farmers and cost-sensitive agricultural production scenarios. At the same time, it continues the north-facing and east-west orientation of the single-slope solar greenhouse and its reasonable single-slope structure design to ensure that the crops inside the greenhouse receive sufficient light and provide key energy support for the crop growth cycle.

[0057] During ventilation, the user opens several ventilation windows 2 and turns on the air exchange module 3, which draws in the warmer air from the top of the inner cavity of the greenhouse body 1 and discharges it into the external environment. This causes the cooler air from the external environment to flow into the interior of the greenhouse body 1 through the ventilation windows 2, forming an air convection path to improve the ventilation efficiency of the inner cavity of the greenhouse body 1.

[0058] Furthermore, such as Figure 1 , 2 As shown, the ventilation window 2 includes: a window 21, an insect-proof net 22, an assembly frame 23, and a switch assembly 24; the window 21 is opened on the plastic film 12 of the greenhouse body 1, and the window 21 is located between a pair of adjacent longitudinal frames 11 of the greenhouse body 1; the insect-proof net 22 covers the outside of the window 21 and is used to cover the window 21; the assembly frame 23 covers the outside of the insect-proof net 22, the inner cavity of the assembly frame 23 matches the position of the window 21, and the assembly frame 23 is fixedly connected to a pair of adjacent longitudinal frames 11.

When the switch assembly 24 closes the window 21, the baffle 243 is attached to the plastic film 12 to close the window 21; in this embodiment, the baffle 243 is preferably made of transparent acrylic sheet.

[0060] When the ventilation window 2 is opened, the user can use the control linkage 242 to drive a pair of mounting rods 241 and the baffle 243 set thereon to flip downwards, thereby releasing the baffle 243 from the window 21 and opening the ventilation window 2.

[0061] When the ventilation window 2 is closed, the user can control the linkage 242 to drive a pair of assembly rods 241 and the baffle 243 set on them to flip upward. After the support rod is flipped into place, the magnetic attraction between the first permanent magnet 2411 on the assembly rod 241 and the assembly frame 23 is used to attract and position the pair of assembly rods 241 and the baffle 243 set on them, and then the baffle 243 is used to close the window 21.

[0062] Furthermore, such as Figures 1-3 As shown, the switch assembly 24 also includes a pair of locking mechanisms 244, which are respectively disposed at both ends of the connecting rod 242. Each locking mechanism 244 is connected to one of the mounting rods 241 and one of the longitudinal frames 11, for fixing the head end of the mounting rod 241 to the longitudinal frame 11.

[0064] When the locking mechanism 244 is opened, the user rotates the connecting rod 242 in the forward direction, causing the lock cylinder rod 2444 to rotate at a certain angle. During the rotation of the lock cylinder rod 2444, under the action of the threaded pair between the lock cylinder rod 2444 and the threaded hole 2442, the lock cylinder rod 2444 is displaced a certain distance along the axial direction of the threaded hole 2442, causing the head end of the lock cylinder rod 2444 to disengage from the lock hole 2443, thereby releasing the locking state of the locking mechanism 244.

[0065] When the locking mechanism 244 is closed, the user rotates the connecting rod 242 in the opposite direction, causing the lock cylinder rod 2444 to rotate at a certain angle. During the rotation of the lock cylinder rod 2444, under the action of the threaded pair between the lock cylinder rod 2444 and the threaded hole 2442, the lock cylinder rod 2444 is displaced a certain distance along the axial direction of the threaded hole 2442, so that the head end of the lock cylinder rod 2444 is inserted into the lock hole 2443, thereby locking the head end of the assembly rod 241.

[0066] Furthermore, such as Figure 1 , 5 As shown, the ventilation module 3 includes: an exhaust pipe 31, several exhaust holes 32, and an exhaust device (not shown in the figure); the exhaust pipe 31 is fixedly installed on the greenhouse body 1, and the head end of the exhaust pipe 31 protrudes from the outer surface of the greenhouse body 1; several exhaust holes 32 are opened on the outer wall of the exhaust pipe 31, and any one of the exhaust holes 32 connects the inner cavity of the exhaust pipe 31 with the top of the inner cavity of the greenhouse body 1, so that the air inside the greenhouse body can flow into the exhaust pipe 31 through the exhaust hole 32; the exhaust device is fixedly installed in the inner cavity of the exhaust pipe 31, and the exhaust device is located at the head end of the exhaust pipe 31, and is used to discharge the air in the inner cavity of the exhaust pipe 31 from the head end of the exhaust pipe 31. In this embodiment, the exhaust device includes, but is not limited to, an exhaust fan.

[0067] Furthermore, such as Figure 1 , 5 As shown, the ventilation module 3 also includes a sealing component 33, which is disposed at the head end of the exhaust pipe 31 and is used to seal the head end port of the exhaust pipe 31.

[0068] Furthermore, such as Figure 1 , 5 As shown in Figure 6, the sealing component 33 includes: an externally threaded tube 331 and an internally threaded cylinder 332; the externally threaded tube 331 is fixedly inserted into the head end port of the exhaust pipe 31, the shape of the externally threaded tube 331 matches the inner cavity of the exhaust pipe 31, and the input end of the externally threaded tube 331 communicates with the inner cavity of the exhaust pipe 31; the internally threaded cylinder 332 is movably sleeved on the output end of the externally threaded tube 331, and the internally threaded cylinder 332 is threadedly connected to the externally threaded tube 331 to seal the port of the output end of the externally threaded tube 331.

[0069] Furthermore, such as Figure 1 , 5As shown in Figure 6, the enclosed component 33 further includes: an assembly hole 333, a pair of hinge holes 334, a pair of hinge posts 336, several limiting protrusions 337, and a second permanent magnet 339; the assembly hole 333 is opened on the end face of one end of the internal threaded cylinder 332, and the position of the assembly hole 333 matches the port of the output end of the external threaded tube 331; a pair of hinge holes 334 are opened on the circumferential inner wall of the assembly hole 333, and the central axes of the pair of hinge holes 334 are collinear; a movable plate 335 is movably disposed in the assembly hole 333, and the shape of the movable plate 335 matches that of the assembly hole 333; a pair of hinge posts 336... 36 is fixedly installed on the circumferential sidewall of the movable plate 335, and a pair of hinged columns 336 are rotatably connected to a pair of hinged holes 334 respectively; a number of limiting protrusions 337 are fixedly installed on the inner wall of the external threaded tube 331, and the number of limiting protrusions 337 are located in the port of the output end of the external threaded tube 331. The gap width between any adjacent pair of limiting protrusions 337 is greater than zero, and the limiting protrusions 337 are magnetic metal parts; the second permanent magnet 339 is fixedly embedded on the movable plate 335, and the farthest distance between the second permanent magnet 339 and the central axis of the hinged hole 334 is equal to the radius of the movable plate 335.

[0071] The three steps to activate the ventilation module are as follows: First, the user drives the internal threaded cylinder 332 to rotate counterclockwise by a certain angle to gradually increase the distance between the assembly hole 333 and the output end of the external threaded pipe 331. As the assembly hole 333 gradually moves away from the output end of the external threaded pipe 331, the second permanent magnet 339 remains in contact with the limiting protrusion 337 under the action of magnetic force, thereby causing the movable plate 335 to deflect. This allows the air output through the external threaded pipe 331 to flow out through the assembly hole 333. Furthermore, as the assembly hole 333 gradually moves away from the output end of the external threaded pipe 331, the ventilation hole 338 on the internal threaded cylinder 332 also connects the assembly hole 333 with the external threaded pipe. The cavity between the output ends of 331 allows air output through the external threaded tube 331 to flow out through the ventilation hole 338, improving the ease of opening the ventilation module 3. Then, the user controls the exhaust device to start, causing the air in the exhaust pipe 31 to be discharged into the external environment through the assembly hole 333 and the ventilation hole 338. In this embodiment, the user can adjust the deflection angle of the movable plate 335 by controlling the screw-out length of the internal threaded cylinder 332, thereby adjusting the open area of ​​the assembly hole 333 of the assembly hole and the number of ventilation holes 338 connecting the cavity between the assembly hole 333 and the output end of the external threaded tube 331, thereby adjusting the maximum exhaust flow of the exhaust pipe 31.
