Description

Technical Field

[0001] This utility model relates to the field of tomato cultivation technology, and in particular to an isolation and insect-proof cover device for transgenic tomato cultivation. Background Technology

[0002] With the continuous advancement of genetic engineering technology, genetically modified tomatoes, as an important vehicle for functional gene verification, stress-resistance breeding, and bioreactor development, are receiving increasing attention for biosafety management in field and pilot-scale trials. To prevent external factors such as insects and pollen from affecting genetically modified tomatoes, they are typically grown in greenhouses.

[0003] For example, a fully enclosed double-membrane carbon dioxide gas-insulated air-supported greenhouse, disclosed in CN218072667U, relates to the field of agricultural environmental protection technology. It includes a greenhouse body, airtight doors, and a ventilation system. The greenhouse body is placed on the ground and includes an inner membrane and an outer membrane spaced around the inner membrane at intervals. The space between the inner and outer membranes is sealed and filled with gas. The space between the inner membrane and the ground is the interior space. The airtight doors are connected to the greenhouse body and are used for access to the interior space. The ventilation system replaces the air in the interior space and maintains a slight positive pressure. This design solves the problems of existing greenhouses, such as small spans hindering mechanized operation, high construction costs, low land utilization, high energy consumption, time-consuming and labor-intensive maintenance, damage to land structure, difficulty in demolition, and the generation of construction waste. However, because the first and second doors lack restraint, it is difficult to ensure that they open and close alternately. Simultaneous opening of the first and second doors could lead to fluctuations in indoor air pressure or even depressurization.

[0004] Therefore, a device for isolating and preventing insects in the cultivation of genetically modified tomatoes has been developed that can ensure that the first and second rotating doors open and close alternately to avoid affecting the air pressure inside the positive pressure greenhouse. Utility Model Content

[0005] To overcome the shortcomings of existing greenhouses, such as the lack of restrictions on the first and second doors, making it difficult to ensure that the first and second doors open and close alternately, and the possibility of the first and second doors opening simultaneously, leading to fluctuations or even depressurization of the indoor air pressure, this utility model provides an isolation and insect-proof cover device for transgenic tomato cultivation that can ensure that the first and second rotating doors open and close alternately, avoiding affecting the internal air pressure of the positive pressure greenhouse.

[0006] The technical solution of this utility model is as follows: an isolation and insect-proof cover device for transgenic tomato cultivation, including a positive pressure greenhouse, a door frame, a first rotating door, a second rotating door, a limiting component, and a windproof component. The door frame is connected to the front right side of the positive pressure greenhouse, the first rotating door is rotatably connected to the front right side of the door frame, and the second rotating door is rotatably connected to the rear right side of the door frame. The door frame is provided with a limiting component that can restrict the opening and closing of the first rotating door and the second rotating door. The positive pressure greenhouse is provided with a windproof component that can block strong winds from entering.

[0007] As a further preferred option, both the first and second revolving doors are equipped with handles.

[0008] As a further preferred embodiment, the limiting component includes a cam, a torsion spring, a limiting rod, and a telescopic spring. The upper sides of both the first and second revolving doors are connected to cams, and torsion springs are connected between the cams and the door frames. A limiting rod is slidably connected to the upper right side of the door frame, and multiple telescopic springs are connected between the limiting rod and the door frame.

[0009] As a further preferred embodiment, the windproof assembly includes an air inlet hood, a motor, gears, and air guide frames. The air inlet hood is connected to the upper rear side of the positive pressure greenhouse, and the motor is connected to the upper right side of the positive pressure greenhouse. Gears are connected to the output shaft of the motor. Two air guide frames are rotatably connected to the upper rear side of the positive pressure greenhouse. The air guide frames are located behind the air inlet hood. The upper air guide frame is connected to the output shaft of the motor, and gears are also connected to the right side of the lower air guide frame. The gears mesh with each other.

[0010] As a further preferred option, the air inlet shroud is equipped with a filter.

[0011] As a further preferred option, the motor and processor are electrically connected via a control module.

[0012] The present invention has the following advantages: 1. When the first rotating door is opened, it drives the front cam to rotate, and the torsion spring is deformed. At this time, the front cam squeezes the limiting rod to move backward, and the front telescopic spring is squeezed and contracted, so that the limiting rod is engaged with the rear cam, so that the second rotating door cannot be opened by rotation. This achieves the effect of ensuring that the first rotating door and the second rotating door open and close alternately, avoiding affecting the air pressure inside the positive pressure greenhouse.

[0013] 2. When the outside wind is strong, this utility model starts the motor, which drives the gear meshing motion, causing the air guide frame to rotate and move closer together to close, thus guiding the wind and preventing strong wind from directly entering the air inlet hood and affecting the indoor air pressure.

[0020] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0021] An isolation and insect-proof cover device for genetically modified tomato cultivation, such as Figures 1-5 As shown, it includes a positive pressure greenhouse 1, a door frame 2, a first rotating door 3, a second rotating door 4, a limiting component, and a windproof component. The door frame 2 is connected to the front right side of the positive pressure greenhouse 1. The first rotating door 3 is rotatably connected to the front right side of the door frame 2. The second rotating door 4 is rotatably connected to the rear right side of the door frame 2. Both the first rotating door 3 and the second rotating door 4 are equipped with handles for easy opening. The door frame 2 is equipped with a limiting component, and the positive pressure greenhouse 1 is equipped with a windproof component.

[0022] like Figures 2-4 As shown, the limiting components include a cam 5, a torsion spring 6, a limiting rod 7, and a telescopic spring 8. The first revolving door 3 and the second revolving door 4 are both connected to the upper side of the cam 5. The cam 5 is connected to the door frame 2 by a torsion spring 6. The upper right side of the door frame 2 is slidably connected to the limiting rod 7. The limiting rod 7 is connected to the door frame 2 by two telescopic springs 8.

[0023] like Figure 1 and Figure 5As shown, the windproof assembly includes an air inlet hood 9, a motor 10, a gear 11, and an air guide frame 12. The air inlet hood 9 is connected to the upper rear side of the positive pressure greenhouse 1. The air inlet hood 9 is equipped with a filter screen to facilitate the interception of external impurities and pests. The motor 10 is connected to the upper right side of the positive pressure greenhouse 1. The motor 10 and the processor are electrically connected through a control module. The gear 11 is connected to the output shaft of the motor 10. The upper and lower air guide frames 12 are rotatably connected to the upper rear side of the positive pressure greenhouse 1. The air guide frames 12 are located behind the air inlet hood 9. The upper air guide frame 12 is connected to the output shaft of the motor 10, and the lower air guide frame 12 is also connected to the right side of the right side of the lower air guide frame 12. The gears 11 mesh with each other.

[0024] When using this invention, the genetically modified tomatoes are first planted in a positive pressure greenhouse 1 to isolate them from external pests. When it is necessary to enter the positive pressure greenhouse 1, the first rotating door 3 is turned and opened to enter the door frame 2. After the first rotating door 3 is closed, the second rotating door 4 is turned and opened to enter the positive pressure greenhouse 1. After entering, the second rotating door 4 is closed, thereby preventing the loss of air pressure in the indoor space.

[0025] When the first revolving door 3 is opened, it drives the front cam 5 to rotate, causing the torsion spring 6 to deform. At this time, the front cam 5 presses the limiting rod 7 to move backward, and the front telescopic spring 8 is compressed and contracted, while the rear telescopic spring 8 is stretched, causing the limiting rod 7 to engage with the rear cam 5, preventing the second revolving door 4 from being opened. After the first revolving door 3 is released, the torsion spring 6 returns to its original position, causing the first revolving door 3 and the front cam 5 to rotate back to their original positions. Then, the telescopic spring 8 rebounds, causing the limiting rod 7 to move forward and disengage from the rear cam 5, allowing the second revolving door 4 to be opened. When the second revolving door 4 is opened, the rear cam 5 presses the limiting rod 7 to move forward and engage with the front cam 5, preventing the first revolving door 3 from being opened. This ensures that the first revolving door 3 and the second revolving door 4 open and close alternately, avoiding affecting the internal air pressure of the positive pressure greenhouse 1.

[0026] When the outside wind is strong, the motor 10 can be started to drive the gear 11 to mesh and move, so that the air guide frame 12 rotates and moves closer to each other to close, thus guiding the wind and preventing strong wind from directly entering the air inlet hood 9 and affecting the indoor air pressure.

[0027] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
