Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-6 The figure shows an automatic ventilation window drive mechanism for a greenhouse, including a support frame 101, side plates 102 on both sides of the support frame 101 and a top plate 103 on the top. The top plate 103 has multiple sets of ventilation openings 104 arranged symmetrically in pairs. Each ventilation opening 104 is hinged to a ventilation window body 105. The mechanism also includes a drive component on the support frame 101 for driving each set of ventilation window bodies 105, and an emergency component on the drive component for emergency response in special circumstances.

[0025] The drive assembly includes multiple sets of fixed plates 201 symmetrically arranged in pairs, which are fixedly connected to the support frame 101. Two sliding plates 203 are connected between two opposite fixed plates 201 through guide rods 202. Support rods 204 are rotatably connected to the side of the two sliding plates 203 near the ventilation window body 105. The other end of the two support rods 204 is connected to the ventilation window body 105. Double-threaded rods 205 are rotatably connected between two opposite fixed plates 201. Two threaded strips with opposite thread directions are opened on the side wall of the double-threaded rod 205. The two sliding plates 203 are threadedly connected to the double-threaded rods 205. The support frame 101 is equipped with a drive motor 206, which is connected to each double-threaded rod 205 through a power connection assembly.

[0026] It should be noted that by setting up the drive component and the emergency component, the ventilation window body 105 is automatically opened and closed under normal circumstances, ensuring the convenience of opening and closing the ventilation window body 105. At the same time, it provides an emergency use method for the ventilation window body 105 in special circumstances such as failure of the drive motor 206 or power interruption, thereby improving the flexibility of the drive mode of the ventilation window body 105.

[0027] Please see Figure 4 The power connection assembly shown in the figure includes multiple support plates 301 fixedly connected to the support frame 101, a power rod 302 rotatably connected between each support plate 301, multiple worm gears 303 fixedly connected to the side wall of the power rod 302, and a worm wheel 304 fixedly connected to the side wall of each double-threaded rod 205, with each worm wheel 304 meshing with the worm gear 303.

[0028] It should be noted that the power assembly allows the output power of the drive motor 206 to be transmitted to each double-ended threaded rod 205, thereby achieving synchronous rotation of each double-ended threaded rod 205. This enables one drive motor 206 to control the opening and closing of multiple ventilation window bodies 105.

[0029] Working principle: When the ventilation window body 105 is openable and closed, the drive motor 206 is started, and under the connection of the emergency component, the power rod 302 is driven to rotate. During the rotation of the power rod 302, each worm gear 303 is driven to rotate. Thus, under the meshing transmission of the worm gear 303 and the worm wheel 304, each double-threaded rod 205 is driven to rotate.

[0030] During the rotation of the double-threaded rod 205, the sliding plate 203 and the double-threaded rod 205 are engaged by threaded transmission and guided by the guide rod 202, which drives the two sliding plates 203 to move away from or towards each other, thereby driving the support rod 204 to rotate, thus realizing the opening and closing of the ventilation window body 105 and ensuring the convenience of opening and closing the ventilation window body 105.

[0031] Example 2

[0032] Please see Figure 5 and Figure 6This embodiment further illustrates Example 1. The emergency component shown in the figure includes an output rod 401 disposed at the output end of the drive motor 206. An emergency tube 402 is fixedly connected to the side of the output rod 401 near the power rod 302. A plurality of insert rods 403 are slidably connected to the emergency tube 402. An insert block 404 is fixedly connected to one end of each insert rod 403 that is close to each other. A plurality of insertion holes 405 are opened on the side wall of the power rod 302. Each insertion hole 405 is matched with the insert block 404. The emergency tube 402 is provided with a pushing component for pushing each insert block 404.

[0033] It should be noted that the power component allows for easy disconnection of the drive motor 206 from the power rod 302, thus providing an emergency method for the ventilation window body 105 in special circumstances such as a failure of the drive motor 206 or a power outage, thereby improving the flexibility of the drive mode of the ventilation window body 105.

[0034] Please see Figure 5 and Figure 6 The emergency tube 402 shown in the figure is equipped with a reset assembly for resetting each plug 404. The reset assembly is a reset spring 5, which is sleeved on the plug rod 403. The two ends of the reset spring 5 are respectively connected to the plug 404 and the inner wall of the emergency tube 402.

[0035] It should be noted here that the setting of the return spring 5 facilitates the movement of each insertion rod 403 away from each other when the pushing amount on the insertion rod 403 is reduced.

[0036] Please see Figure 5 and Figure 6 The push assembly shown in the figure includes a push ring 601 threaded to the side wall of the emergency tube 402. A conical ring 602 is fixedly connected to the side of the push ring 601 near the power rod 302. The ends of each insertion rod 403 that are far apart from each other are slidably connected to the inner wall of the conical ring 602.

[0037] It should be noted here that by setting up the push component, it is easy to push the plug 404 at one end of each plug rod 403 to move closer to each other, thereby realizing the connection between the output rod 401 and the power rod 302.

[0038] Working principle: When the drive motor 206 malfunctions or experiences a power outage, preventing it from functioning properly, the operator can use a ladder to climb up to a position close to the drive motor 206, ensuring safety. Then, by rotating the push ring 601, the conical ring 602 moves away from the power rod 302 under the action of threaded meshing. As the conical ring 602 moves away from the power rod 302, the pushing force on the insertion rod 403 gradually decreases. Under the elastic action of the return spring 5, the insertion rods 403 move away from each other, causing the insertion blocks 404 to move out of the insertion holes 405 on the side wall of the power rod 302. This disconnects the output rod 401 at the output end of the drive motor 206 from the power rod 302.

[0039] After the output rod 401 is connected to the power rod 302, the operator who has climbed to a high place can rotate the rotating ring 7 to drive the power rod 302 to rotate, thereby realizing the opening and closing of the ventilation window body 105. This provides an emergency method for the ventilation window body 105 in special circumstances such as failure of the drive motor 206 or power outage, thereby improving the flexibility of the driving mode of the ventilation window body 105.

[0040] Example 3

[0041] Please see Figure 5 This embodiment is a further explanation of other embodiments. In the figure, a rotating ring 7 is fixedly connected to the side wall of the power rod 302, and the side wall of the rotating ring 7 is frosted.

[0042] It should be noted here that the rotating ring 7 facilitates the manual rotation of the power rod 302.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
