Description

Technical Field

[0001] This utility model relates to the field of fruit breeding and planting greenhouse technology, specifically a high-efficiency ventilation device for fruit breeding and planting greenhouses. Background Technology

[0002] Fruit breeding refers to the improvement and innovation of fruit varieties through scientific and technological means to cultivate new varieties with superior traits. This process involves a variety of modern technologies, including traditional breeding techniques and biotechnology. By applying these technologies, fruit breeding can not only improve the quality and yield of fruits but also meet the market's demand for diversified fruits.

[0003] However, in current technology, planting sheds are typically used outdoors. But when planting sheds are used in coastal or plain areas, these areas often experience extreme weather such as strong winds or sea breezes. In windy weather, the outer covering film of the planting shed increases the contact area with the wind, which makes the shed more susceptible to the impact of strong winds during extreme weather, and there is a risk of deformation or collapse. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency ventilation device for fruit breeding greenhouses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency ventilation device for fruit breeding greenhouses includes a support frame with a base at the bottom. The support frame contains a support assembly for resisting extreme weather conditions. The support assembly includes a column located in the central area of ​​the support frame, with a cylinder at the bottom of the column. Multiple connecting frames are located inside the support frame. Each connecting frame has a positioning groove at one end and an insertion rod at the other end. The inner wall of the positioning groove has a cavity containing a rack and a spring. An electromagnet is installed on the inner wall of the cavity. A locking tooth is provided on one side of the outer wall of the insertion rod.

[0007] As a preferred embodiment of this utility model, the bottom of the support frame is embedded in the base and is rotatably connected to the inner wall of the base via a connecting shaft, and the connecting shaft and the inner wall of the base can also be slidably connected.

[0008] As a preferred embodiment of this utility model, the support frame is divided into two ends from the center, and the column is located in the middle of the support frame. The end of the support frame is embedded in the column and rotatably connected to the inner wall of the column. One end of the cylinder extends to the ground, and the output end is connected to the bottom of the column by bolts.

[0009] As a preferred embodiment of this utility model, the support frame is divided into multiple connecting frames, and the multiple connecting frames are distributed in an array. One end of the insertion rod is connected to one end of the connecting frame by a bolt, and the other end extends into the positioning groove of another connecting frame, and is slidably connected to the inner wall of the positioning groove.

[0010] As a preferred embodiment of this utility model, the cavity is distributed on one side of the inner wall of the positioning groove and corresponds to the locking teeth on the outer wall of the insertion rod. One end of the rack is located in the cavity and is slidably connected to the inner wall of the cavity. Both ends of the spring are connected to the inner wall of the cavity and the rack respectively by welding.

[0011] As a preferred embodiment of this utility model, after the insertion rod is embedded in the positioning groove, the retaining teeth on the outer wall abut and mesh with the rack, and the electromagnet is embedded and connected to the inner wall of the cavity, and can generate magnetic poles that are magnetically connected to the rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems raised in the background art, this application adopts a support component, which supports the greenhouse support frame through the column. When encountering strong winds, the cylinder and column drive the support frame to rise. At the same time, the multiple connecting frames in the support frame rotate to change the support frame from an arc shape to a triangular structure. The connecting frames are reinforced by locking the interlocking teeth. The triangular structure of the support frame can distribute the thrust generated by strong winds to three points, reinforcing the greenhouse and increasing its stability in strong winds, making it more resistant to strong winds and other severe weather conditions.

[0013] This invention enables the greenhouse support frame to be switched into a triangular structure, which disperses the pressure caused by strong winds, improves the greenhouse's ability to resist strong winds and other severe weather conditions, increases the greenhouse's stability, and protects the planted fruit.

[0020] The support frame 1 is internally provided with multiple connecting frames 4 for connecting the support frame 1 that forms the planting shed. Each of the multiple connecting frames 4 has a positioning groove 401 at one end and an insertion rod 6 at the other end. The insertion rod 6 can be inserted into the positioning groove 401 of another connecting frame 4, thereby connecting the multiple connecting frames 4 and making them work together. The inner wall of the positioning groove 401 is provided with a cavity 5 for providing space for the rack 501 to retract. The cavity 5 is provided with a rack 501 and a spring 502. When the insertion rod 6 is inserted into the positioning groove 401, the rack 501 can engage with the retaining teeth 7 on the outer wall of the insertion rod 6, thereby securing the insertion rod 6. Positioning and locking: Spring 502 supports rack 501 and pushes it out of cavity 5. Electromagnet 503 is provided on the inner wall of cavity 5. When activated, electromagnet 503 can magnetically attract magnetic plate embedded in rack 501, thereby driving rack 501 to retract into cavity 5 and lock the insertion rod 6. A locking tooth 7 is provided on one side of the outer wall of insertion rod 6. When column 3 is raised, it drives the center of support frame 1 to rise downward and deform, thereby changing from arc structure to triangular structure. The triangular structure increases the stability of planting shed and can disperse the pressure of strong winds to three points, improving the ability to resist strong winds.

[0021] In this embodiment, all electrical components are controlled by a conventional controller.

[0022] For an example, please refer to... Figure 1-3The support frame 1 is embedded in the base 2 at its bottom and is rotatably connected to the inner wall of the base 2 via a connecting shaft. The connecting shaft and the inner wall of the base 2 can also be slidably connected. The support frame 1 is divided into two ends from its center, with a column 3 located in the middle of the support frame 1. The end of the support frame 1 is embedded in the column 3 and rotatably connected to the inner wall of the column 3. One end of the cylinder 301 extends to the ground, and its output end is connected to the bottom of the column 3 via bolts. The support frame 1 is segmented into multiple connecting frames 4, and these connecting frames 4 are arranged in an array. One end of the insertion rod 6 is connected to one end of the connecting frame 4 via bolts, and the other end extends... The rod extends into the positioning groove 401 of another connecting frame 4 and is slidably connected to the inner wall of the positioning groove 401.

One end of the rack 501 is located in the cavity 5 and is slidably connected to the inner wall of the cavity 5. Both ends of the spring 502 are connected to the inner wall of the cavity 5 and the rack 501 respectively by welding. After the insertion rod 6 is embedded in the positioning groove 401, the locking teeth 7 on the outer wall abut and mesh with the rack 501. The electromagnet 503 is embedded and connected to the inner wall of the cavity 5 and can generate magnetic poles and magnetically connect with the rack 501. In use, during strong winds, the PLC controller controls the cylinder 301 area to lift the column 3. At the same time, the column 3 lifts the end of the support frame 1 near the column 3 downwards, and the connecting frame 4 deforms. The insertion rod 6 at one end of the connecting frame 4 extends into the positioning groove 401 of the other connecting frame 4, and the locking teeth 7 on the outer wall of the insertion rod 6 mesh with the rack 501 in the positioning groove 401, so that the support frame 1 changes from an arc-shaped structure to a triangular structure to resist strong winds.

[0023] The working process of this utility model is as follows: In strong winds, the PLC controller controls the cylinder 301 to raise the column 3. Simultaneously, the column 3 raises the support frame 1 near the end of the column 3 downwards, and the connecting frame 4 deforms. The insert rod 6 at one end of the connecting frame 4 extends into the positioning groove 401 of the other connecting frame 4, and the retaining teeth 7 on the outer wall of the insert rod 6 engage with the rack 501 in the positioning groove 401, causing the support frame 1 to change from an arc-shaped structure to a triangular structure to resist strong winds. This utility model enables the greenhouse support frame to switch to a triangular structure, dispersing the pressure caused by strong winds, improving the greenhouse's ability to resist strong winds and other severe weather conditions, increasing the stability of the greenhouse, and protecting the planted fruit.
