[0021] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0022] See also Figure 1 and Figure 2 The utility model provides a smart agricultural greenhouse ventilation device, including an exhaust fan 1, a mounting frame 2 is provided on the surface of the exhaust fan 1, an intelligent driving device is built into the mounting frame 2, a sealing plate 3 is provided in the mounting frame 2, a plate mounting structure 4 is provided in the mounting frame 2, the plate mounting structure 4 is connected to the intelligent driving device and is driven to rotate by the intelligent driving device, and the sealing plate 3 is connected to the plate mounting structure 4;

[0023] Turn on the exhaust fan 1, and the exhaust fan 1 will exhaust the air in the agricultural greenhouse to the outside, thereby achieving ventilation. The rotation and closing of the sealing plate 3 can close the vent when the greenhouse needs to be kept at a constant temperature.

[0024] See also Figure 2 、 Figure 3 and Figure 4 The utility model provides a smart agricultural greenhouse ventilation device. The plate mounting structure 4 includes a rotating tube 41. The rotating tube 41 is arranged inside the mounting frame 2, and the rotating tube 41 is driven by the mounting frame 2.

[0025] The interior of the rotating tube 41 is equipped with a sliding tube 42 that is connected in a transverse sliding manner. A snap ring 401 is installed at the middle end of the rotating tube 41. The sliding tube 42 passes through the middle of the snap ring 401 and is slidably connected to the snap ring 401, thereby improving the sliding stability of the sliding tube 42 and preventing the sliding tube 42 from shaking when sliding.

[0026] The slide tube 42 is provided with a bayonet 43, in which a block 44 is integrally formed. A paddle 45 is integrally formed on the surface of the slide tube 42, which is slidably connected to the rotating tube 41. A second stopper 451 is integrally formed on the surface of the paddle 45. The second stopper 451 is arc-shaped and covers the connection between the rotating tube 41 and the paddle 45, effectively preventing dust from entering the interior of the rotating tube 41.

[0027] Springs 46 are installed at both ends of the rotating tube 41. The left and right ends of the sliding tube 42 are respectively connected to the springs 46 at both ends. A telescopic rod 461 is installed inside the spring 46. The telescopic end of the telescopic rod 461 is connected to the sliding tube 42 to position the end of the sliding tube 42, thereby improving the stability of the sliding tube 42.

[0028] A docking port 47 is formed on the rotating tube 41, and three inserts 48 are integrally formed on the sealing plate 3. The number of the bayonet 43 is the same as the inserts 48. The three inserts 48 are respectively located at the left and right ends and the middle of the sealing plate 3, making the sealing plate 3 more stable after installation. A baffle 481 is integrally formed on the surface of the insert 48. The baffle 481 is arc-shaped. The insert 48 is docked with the docking port 47. The baffle 481 can cover the connection between the insert 48 and the rotating tube 41, thereby improving the protective effect.

[0029] When the sealing plate 3 needs to be removed, the staff slides the paddle 45 and pushes the slide tube 42 to slide rightward inside the rotating tube 41, thereby driving the block 44 to slide out of the insert 48, thereby releasing the limit on the insert 48. At this time, the spring 46 is deformed under the force and generates elastic force. After the limit on the insert 48 is released, the staff can remove the sealing plate 3, so that the insert 48 slides out of the rotating tube 41, so as to achieve convenient disassembly. When installing, slide the paddle 45 to slide the slide tube 42, and then insert the insert 48 on the sealing plate 3 into the interior of the rotating tube 41 and dock with the bayonet 43. Release the paddle 45. Under the action of the spring 46, the slide tube 42 returns to its original position and slides, so that the block 44 is stuck in the insert 48, and the insert 48 is limited to achieve convenient installation of the sealing plate 3, achieving a more convenient beneficial effect when the sealing plate 3 is damaged and needs to be disassembled, replaced or installed.
