Technical Field
[0001] This utility model relates to the technical field of ventilation and temperature control, and in particular to a ventilation and temperature control structure for greenhouses. Background Technology
[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and provides insulation or heating for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield. It is primarily used for cultivating or raising seedlings of warm-weather-loving vegetables, flowers, and trees during cold seasons. Greenhouses come in many types, categorized by their roof frame materials, lighting materials, shape, and heating conditions. A simple plastic film greenhouse, on the other hand, has fewer internal facilities and lower requirements than a greenhouse. Therefore, strictly speaking, greenhouses have higher equipment requirements than plastic film greenhouses and may require more advanced instruments for strict temperature control.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: Traditional ventilation requires staff to open the greenhouse, which not only wastes a lot of time and energy for the staff, but is also inconvenient to close. In the event of extreme weather, the greenhouse cannot be closed quickly, which may lead to staff injury and property damage. Therefore, in order to address the above problems, a greenhouse ventilation and temperature control structure is proposed. Utility Model Content
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the ventilation of the greenhouse is done by the staff, which not only wastes a lot of time and energy, but is also inconvenient to close.

[0009] Preferably, a spring is fixedly connected to the inner wall of the slide groove of the cover plate, and a slide rod is fixedly connected to the other end of the spring.
[0010] The effect achieved by the above components is that, through the cooperation of the spring slide rod and the moving block, when the moving block is pulled to drive the slide rod to release the moving block, the spring's own elastic force automatically drives the slide rod back to its original position.
[0011] Preferably, a protective net is fixedly connected to the surface of the fixed frame, and the size of the fixed groove is adapted to the size of the slide rod.
[0012] The effect achieved by the above components is that, through the combination of protective netting and fixed frame, birds can be effectively prevented from flying into the greenhouse when the ventilation is opened.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a greenhouse ventilation and temperature control structure, including a fixed frame 1. The surface of the fixed frame 1 is provided with a switch device 2. By setting the switch device 2, the cover plate 22 can be opened, avoiding the traditional ventilation method where workers open the greenhouse when not in use, which not only wastes a lot of time and energy but is also inconvenient to close. In extreme weather, the greenhouse cannot be closed quickly, resulting in worker injury and property damage. This improves the usability of the device. The surface of the fixed frame 1 is provided with an auxiliary device 3. By setting the auxiliary device 3, the greenhouse interior can be cooled quickly. Different sizes of wet curtain frames 32 can be replaced according to the actual situation inside the greenhouse and the wind speed. The installation of wet curtain frames 32 can also be determined based on the temperature inside the greenhouse to quickly cool the greenhouse, improving the practicality of the device.
[0031] The specific setup and function of its switching device 2 and auxiliary device 3 will be described in detail below.
[0032] Reference Figure 2As shown in this embodiment: the switch device 2 includes a round rod 21, both ends of which are fixedly connected to the surface of the fixed frame 1. A cover plate 22 is slidably connected to the arc surface of the round rod 21. A groove is formed on the surface of the cover plate 22. A slide rod 23 is slidably connected to the inner wall of the groove of the cover plate 22. A moving hole 24 is formed on the surface of the cover plate 22. A moving block 25 is slidably connected to the inner wall of the moving hole 24. One end of the moving block 25 is fixedly connected to the slide rod 23. A fixing groove 26 is formed on the surface of the fixed frame 1. A torsion spring 27 is sleeved on the arc surface of the round rod 21. Both ends of the torsion spring 27 are fixedly connected to the surface of the cover plate 22 and the surface of the fixed frame 1, respectively. The inner wall of the groove of the cover plate 22 is fixedly connected to the inner wall of the groove of the cover plate 22. A spring 28 is connected, and a slide rod 23 is fixedly connected to the other end of the spring 28. A protective net 29 is fixedly connected to the surface of the fixed frame 1. The size of the fixed groove 26 is adapted to the size of the slide rod 23. Through the cooperation of the torsion spring 27, the cover plate 22, and the fixed frame 1, when the cover plate 22 is opened, the torsion force of the torsion spring 27 drives the cover plate 22 to open automatically. Through the cooperation of the spring 28, the slide rod 23, and the moving block 25, when the moving block 25 is pulled to drive the slide rod 23 to release the moving block 25, the elastic force of the spring 28 automatically drives the slide rod 23 to return to its original position. Through the cooperation of the protective net 29 and the fixed frame 1, birds can be effectively prevented from flying into the greenhouse when the ventilation is opened.
[0033] Reference Figure 3 As shown, specifically, the auxiliary device 3 includes a concave frame 31, which is fixedly connected to the surface of the fixed frame 1. A moving groove is provided on the surface of the concave frame 31, and a wet curtain frame 32 is slidably connected in the moving groove of the concave frame 31. A screw 33 is threaded into the concave frame 31, and an elliptical block 34 is fixedly connected to one end of the screw 33. A limiting groove 35 is provided on the surface of the wet curtain frame 32, and the size of the screw 33 is adapted to the size of the limiting groove 35. Two L-shaped plates 36 are fixedly connected to the surface of the concave frame 31, and the L-shaped plates 36 are adapted to the wet curtain frame 32. Through the screw 33, the wet curtain frame 32, and the limiting groove 35, the wet curtain frame 32 can be moved to one side and fixed by the limiting groove 35 when it is not in use. Through the cooperation of the two L-shaped plates 36 and the concave frame 31, the position of the wet curtain frame 32 can be quickly found and installed when it is installed.
[0034] Working principle: When the staff needs to open the ventilation, the staff pulls the movable block 25 to slide on the inner wall of the movable hole 24. The movable block 25 drives the slide rod 23 to slide in the groove of the cover plate 22. The slide rod 23 drives the spring 28 to retract. The slide rod 23 moves away from the inner wall of the fixed groove 26. Due to the torsion of the torsion spring 28 itself, the torsion spring 28 drives the cover plate 22 to open automatically. The cover plate 22 rotates on the arc surface of the round rod 21, so that the staff can complete the ventilation.
[0035] When the staff replaces the wet curtain frame 32, the staff rotates the elliptical block 34, which drives the screw 33 to rotate. The staff then pulls the wet curtain frame 32 to slide within the moving groove of the concave frame 31 until it is fully pulled out. A new wet curtain frame 32 is then installed, which is inserted into the L-shaped plate 36. The staff then pushes it directly into the moving groove of the concave frame 31 and rotates the elliptical block 34 to drive the screw 33 to engage the wet curtain frame 32. Alternatively, when the wet curtain frame 32 is not needed, the screw 33 can be engaged into the limiting groove 35, thereby improving practicality.
