Description

Technical Field

[0001] This invention belongs to the field of greenhouse ventilation technology, specifically relating to a circulating ventilation system for a smart agricultural greenhouse. Background Technology

[0002] A greenhouse, also known as a hothouse, is a room equipped with facilities for frost protection, heating, and light transmission, used for cultivating warm-loving plants during winter. It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, generational breeding, and ornamental plant cultivation; it has the function of protecting plant growth and increasing plant yield.

[0003] Existing agricultural greenhouse ventilation and circulation systems are usually fixed with screws, which require a lot of tools to disassemble. This makes it inconvenient to install and disassemble the ventilation unit, resulting in increased time spent on cleaning, maintenance, or replacement of parts, and increased labor costs. Especially during seasonal maintenance or sudden failures, it can affect ventilation and production continuity. Utility Model Content

[0004] The purpose of this invention is to provide a circulating ventilation system for a smart agricultural greenhouse, which allows for quick assembly and disassembly of the ventilation unit, facilitating replacement and maintenance; at the same time, by adjusting the air volume of each ventilation duct through the ventilation unit, it can promote the growth of different plants in the greenhouse.

[0005] The specific technical solution adopted by this utility model is as follows: A circulating ventilation system for a smart agricultural greenhouse includes a ventilation body, with connecting pipes fixed at both the upper and lower ends of the ventilation body, and the rear side of the ventilation body is fixedly connected to a connecting plate. The mounting plate has a mounting groove on its front side. The connecting plate is slidably connected to the mounting groove. A sliding hole is opened on one side of the mounting plate. A driving rod is slidably connected inside the sliding hole. One end of the driving rod inside the sliding hole is fixedly connected to one side of a limiting block. The limiting block is slidably connected to the connecting plate. A reset plate is fixed to the outside of the driving rod. The outside of the reset plate is slidably connected to the sliding hole. An elastic element is assembled between the sliding hole and the reset plate.

[0006] Furthermore, the connecting plate is T-shaped and has a limiting hole, and the limiting block is slidably connected to the limiting hole.

[0007] Furthermore, the mounting plate also has a limiting groove inside, which extends through the mounting groove and is connected to the sliding hole. The limiting block is slidably connected to the limiting groove.

[0008] Furthermore, a sealing plate is fixed to the outside of the connecting pipe, and a fixed cylinder is rotatably connected to the outside of the sealing plate, with an internal thread inside the fixed cylinder.

[0009] Furthermore, the ventilation body has multiple control valves fixed inside, all of which are fixedly connected to the bottom of the connecting pipe, and all of these control valves are electric air volume regulating valves.

[0010] Furthermore, a control panel is fixed to the front side of the ventilation body, and the control panel is electrically connected to multiple control valves respectively.

[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a circulating ventilation system for a smart agricultural greenhouse. By separating the ventilation body from the mounting plate, the system can quickly release the limiting fixation of the water control body, facilitating the replacement and maintenance of the water control body. This ensures that installation and disassembly can be completed without the use of complex tools during maintenance, significantly shortening working time and improving maintenance efficiency. At the same time, the split design allows for the individual replacement of faulty components, extending the service life of the equipment and reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figures 1 to 4As shown, a circulating ventilation system for a smart agricultural greenhouse includes a ventilation body 10, with connecting pipes 11 fixed at both the upper and lower ends of the ventilation body 10, and the rear side of the ventilation body 10 is fixedly connected to a connecting plate 12. Mounting plate 20 has a mounting groove 21 on its front side. Connecting plate 12 is slidably connected to mounting groove 21. Mounting plate 20 has a sliding hole 201 on one side. A driving rod 22 is slidably connected inside the sliding hole 201. One end of the driving rod 22 inside the sliding hole 201 is fixedly connected to one side of a limiting block 23. The limiting block 23 is slidably connected to connecting plate 12. A reset plate 221 is fixed to the outside of the driving rod 22. The outside of the reset plate 221 is slidably connected to the sliding hole 201. An elastic element 24 is assembled between the sliding hole 201 and the reset plate 221.

[0016] In this embodiment, it should be noted that an air inlet is provided on one side of the ventilation body 10. The air inlet is connected to the circulating fan box via a pipe. The circulating fan box can force airflow circulation, thereby enabling the ventilation body 10 to effectively control the ventilation distribution in the greenhouse and achieve circulating ventilation inside the greenhouse. This is a conventional technology and will not be elaborated further here. Furthermore, the mounting plate 20 has fixing holes on both the upper and lower parts. These fixing holes, in conjunction with fixing screws, can effectively fix the mounting plate 20 in a suitable position, enabling the ventilation body 10 to be portable. The elastic element 24 is a compression spring. Initially, the elastic element 24 is in a compressed state. Both ends are fixedly connected to the sliding hole 201 and the reset plate 221 respectively. When the drive rod 22 is pulled, a force is applied to the elastic element 24, which in turn causes the elastic element 24 to deform and extend to store energy. Subsequently, when the ventilation body 10 drives the connecting plate 12 to be located in the mounting groove 21 inside the mounting plate 20, the drive rod 22 is released. At this time, the drive rod 22 and the elastic element 24 are not subject to external force. The elastic element 24 releases energy, which drives the reset plate 221, the drive rod 22 and the limiting block 23 to move, so that the limiting block 23 is slidably connected to the limiting hole 121 opened in the connecting plate 12, thus completing the fixed limiting of the ventilation body 10.

[0017] like Figure 3 As shown, the connecting plate 12 is T-shaped, and a limiting hole 121 is provided on the connecting plate 12. The limiting block 23 is slidably connected to the limiting hole 121. The T-shaped connecting plate 12 can ensure stability when connected to the mounting plate 20, and ensure safety during the use of the ventilation body 10.

[0018] Preferably, the mounting plate 20 also has a limiting groove 202 inside, the limiting groove 202 passes through the mounting groove 21, and the limiting groove 202 is connected to the sliding hole 201, and the limiting block 23 is slidably connected to the limiting groove 202.

[0019] In this embodiment, the limiting groove 202 is connected to the sliding hole 201. When the drive rod 22 is pulled, the limiting block 23 will move synchronously in the limiting groove 202, thereby separating the limiting block 23 from the limiting groove 202 on the other side of the mounting groove 21. After the replacement is completed, the elastic element 24 releases energy by releasing the drive rod 22, thereby driving the reset plate 221 and the drive rod 22 to move, thereby pushing the limiting block 23 to slide in the limiting groove 202 and pass through the mounting groove 21 to complete the reset.

[0020] like Figure 2 , Figure 3 As shown, a sealing plate 111 is fixed to the outside of the connecting pipe 11, and a fixed cylinder 13 is rotatably connected to the outside of the sealing plate 111. The fixed cylinder 13 has an internal thread. It should be noted that the inner diameter of the fixed cylinder 13 matches the outer diameter of the ventilation pipe and is threadedly connected to the ventilation pipe. When the ventilation pipe needs to be connected, the ventilation pipe is screwed tightly onto the fixed cylinder 13, and then the end of the ventilation pipe will contact the sealing plate 111, thereby ensuring that no leakage occurs when the ventilation body 10 is circulating ventilation.

[0021] Preferably, the ventilation body 10 has multiple control valves fixed inside, all of which are fixedly connected to the bottom of the connecting pipe 11, and all of the control valves are electric air volume regulating valves.

[0022] Preferably, a control panel 101 is fixed to the front side of the ventilation body 10, and the control panel 101 is electrically connected to a plurality of control valves respectively.

[0023] In the above embodiments, based on the first embodiment, by connecting the ventilation pipe to the connecting pipe 11, and then driving the connecting plate 12 to be placed in the mounting groove 21 through the ventilation body 10, by controlling the control panel 101 located outside the ventilation body 10, a control signal is sent to the control valve, thereby adjusting the air volume delivered by the control valve (conventional technology, which will not be elaborated in detail here). It is possible to adjust the air volume of different pipes according to different plants in the greenhouse to ensure the promotion of plant growth.

[0024] The working principle of this utility model is as follows: In use, the mounting plate 20 is fixed in a suitable position beforehand, and then the ventilation body 10 is connected to the ventilation circulation device; the ventilation pipe is assembled with the connecting pipe 11 in sequence to ensure effective ventilation circulation; subsequently, by pulling the drive rod 22, the drive rod 22 moves the reset plate 221 and the limiting block 23 within the limiting groove 202 and the sliding hole 201; simultaneously, when the reset plate 221 moves, it pulls one end of the elastic element 24, thereby applying force to the elastic element 24, causing it to deform and extend to store energy; when the drive rod 221 moves... The ventilation body 10 connects its back connecting plate 12 to the mounting groove 21, ensuring that the bottom of the connecting plate 12 is in contact with the bottom of the mounting groove 21. Then, the drive rod 22 is released. At this time, the elastic element 24 is not subjected to external force and releases energy to recover. At the same time, through the reset plate 221 fixedly connected to it, the drive rod 22 and the limiting block 23 are moved, so that the limiting block 23 is slidably connected to the limiting hole 121 in the connecting plate 12, and passes through the connecting plate 12 to connect with the limiting groove 202 on the other side of the mounting groove 21, ensuring the safety and stability of the ventilation body 10 during use.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
