The various technical effects of the preferred solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Furthermore, the support includes brackets fixedly connected to the inner wall of the outer shell, with fixed rods passing through two brackets, and both brackets being fixedly connected to the fixed rods; wherein, a plurality of rotating shafts are rotatably connected to the fixed rods on the side closest to the fixed rods, and a rotation space is reserved between the outer wall of the fixed rods and the inner wall of the outer shell, and a plurality of baffles.

[0008] Furthermore, the sealing replenishment part includes a sealing assembly mounted on a fixed rod; and an elastic assembly, wherein a plurality of elastic assemblies are arranged in a circumferential array on the inner wall of the housing; wherein the sealing assembly is located on the rear side of the adjustment part and seals its reserved space after the adjustment part is closed.

[0009] Furthermore, the power assembly includes a motor housing connected to the outer wall of the outer casing, a motor fixedly connected to the rear inner wall of the motor housing, a second rotating shaft fixedly connected to the output shaft of the motor via a coupling, and a gear fixedly connected to the outer wall of the second rotating shaft; wherein, the front side of the second rotating shaft is rotatably connected to the front inner wall of the motor housing.

[0010] Furthermore, the sealing assembly includes a sealing ring 1 slidably connected to the outer wall of the fixed rod, a plurality of connecting rods being fixedly connected to the outer wall of the sealing ring 1, and a sealing ring 2 being fixedly connected to the side of the plurality of connecting rods away from the sealing ring 1, the outer wall of the sealing ring 2 being slidably connected to the outer shell; wherein, the front sides of the sealing ring 1 and the sealing ring 2 abut against a plurality of baffles.

[0027] The following is combined with Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0028] This utility model provides a ventilation structure for a greenhouse, including an outer shell 111 and an annular groove 112 formed thereon, and further including: a support part 1, which is installed on the inner wall of the outer shell 111; an adjustment part 2, which is disposed inside the outer shell 111; and a sealing and supplementing part 3, which is installed on the outer shell 111.

[0030] In some embodiments of the present invention described above, the sealing component 31 is mounted on the fixed rod 114 and slidably connected to the outer shell 111. After the adjustment part 2 is closed, it abuts against the baffle 212 through the sealing ring 1 311 and the sealing ring 2 313, effectively sealing the reserved space between the baffle 212 and the outer wall of the fixed rod 114 and the inner wall of the outer shell 111, making up for any gaps that may exist when the adjustment part 2 is closed, enhancing the overall sealing performance, preventing gas leakage when ventilation is not required, and ensuring the stability of parameters such as temperature and humidity inside the greenhouse. The elastic component 32 provides a continuous elastic force to the sealing component 31 through the spring telescopic rod 323 in a compressed state, so that the sealing ring 1 311 and the sealing ring 2 313 always abut against the baffle 212 tightly, ensuring the reliable sealing effect of the sealing component 31 when the adjustment part 2 is closed, and improving the sealing stability of the ventilation structure.

[0031] In some embodiments of this utility model, the sealing replenishment part 3 includes a sealing assembly 31, which is mounted on the fixed rod 114; and an elastic assembly 32, of which a plurality of elastic assemblies 32 are arranged in a circumferential array on the inner wall of the outer casing 111; wherein, the sealing assembly 31 is located behind the adjusting part 2, and seals the reserved space therein after the adjusting part 2 is closed, and the sealing assembly 31 includes a sealing ring 311 slidably connected to the outer wall of the fixed rod 114, and a plurality of connecting rods 31 are fixedly connected to the outer wall of the sealing ring 311. 2. A sealing ring 313 is fixedly connected to one side of several connecting rods 312 away from the sealing ring 311. The outer wall of the sealing ring 313 is slidably connected to the outer shell 111. The front sides of the sealing ring 311 and the sealing ring 313 abut against several baffles 212. The elastic component 32 includes a hinge block 321 fixedly connected to the inner wall of the outer shell 111. The outer wall of the corresponding connecting rod 312 is fixedly connected to a hinge block 322. A spring telescopic rod 323 is provided between the two hinge blocks 322. The spring telescopic rod 323 is in a compressed state.

[0032] In some embodiments of the present invention described above, the sealing component 31 is mounted on the fixed rod 114 and slidably connected to the outer shell 111. After the adjustment part 2 is closed, it abuts against the baffle 212 through the sealing ring 1 311 and the sealing ring 2 313, effectively sealing the reserved space between the baffle 212 and the outer wall of the fixed rod 114 and the inner wall of the outer shell 111, making up for any gaps that may exist when the adjustment part 2 is closed, enhancing the overall sealing performance, preventing gas leakage when ventilation is not required, and ensuring the stability of parameters such as temperature and humidity inside the greenhouse. The elastic component 32 provides a continuous elastic force to the sealing component 31 through the spring telescopic rod 323 in a compressed state, so that the sealing ring 1 311 and the sealing ring 2 313 always abut against the baffle 212 tightly, ensuring the reliable sealing effect of the sealing component 31 when the adjustment part 2 is closed, and improving the sealing stability of the ventilation structure.

[0033] Example 1: In use, when the ventilation of the adjustment section 2 is opened, the motor 222 is started. The motor 222 drives the gear 224 to rotate through the rotating shaft 223. The gear 224 drives several cylindrical slide rods 215 to rotate around the fixed rod 114 through the meshing gear ring 214. Thus, the several cylindrical slide rods 215 drive several rotating shafts 211 to rotate through several guide rails 216. The several rotating shafts 211 drive several baffles 212 to rotate, thereby opening the air duct of the outer shell 111. The degree of opening of the air duct can be controlled by controlling the rotation angle of the baffles 212. Conversely, controlling the motor 222 to reverse will drive the several baffles 212 to reverse and reduce or close the air duct.

[0034] Example 2: When the air duct is opened, the several baffles 212 rotate and squeeze the sealing ring 2 313, causing it to move backward. The sealing ring 2 313 drives the sealing ring 1 311 to move backward synchronously under the guidance of the fixed rod 114 through several connecting rods 312. This causes the several fixed rods 114 to compress the corresponding spring telescopic rods 323 through several hinge blocks 2 322. When the air duct is closed, the several spring telescopic rods 323 rebound and cause the sealing ring 1 311 and the sealing ring 2 313 to be in close contact with the several baffles 212, thereby sealing the reserved space between the several baffles 212 and the inner wall of the outer shell 111 and the outer wall of the fixed rod 114.
