Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse planting equipment, specifically to a ventilation device for greenhouses. Background Technology

[0002] A glass greenhouse is a common type of greenhouse, constructed primarily of glass. It is typically used for agricultural production, plant cultivation, and scientific research. It effectively utilizes sunlight, provides suitable temperature and humidity environments to promote plant growth, extend the plant's growth cycle, and increase yield.

[0003] Regular ventilation is necessary during the cultivation process in glass greenhouses. This is primarily to regulate the temperature and humidity inside the greenhouse and promote air circulation to ensure normal plant growth. Proper ventilation not only prevents excessively high temperatures inside the greenhouse, reducing the occurrence of pests and diseases, but also ensures air renewal and improves photosynthetic efficiency.

[0004] Currently, ventilation methods for glass greenhouses generally include natural ventilation and mechanical ventilation. Natural ventilation mainly utilizes fixed openings in the greenhouse for ventilation, while mechanical ventilation mainly uses fans or other mechanical equipment to force airflow to achieve the ventilation effect.

[0005] Regarding the natural ventilation method for glass greenhouses, the inventor believes that since natural ventilation mainly utilizes fixed window openings on the greenhouse, these openings are generally open structures, which may affect the temperature inside the greenhouse and cause leaks during long-term use.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-6 .

[0028] To address the problems mentioned in the background section, this utility model provides a ventilation device for greenhouses to solve the aforementioned technical problems. The technical solution is as follows:

[0029] A ventilation device for a greenhouse includes: a U-shaped frame 100, square slats 120, a sealing baffle 110, a rack 140, a gear 150, and a first motor 160; the U-shaped frame 100 is the structural skeleton of the ventilation device and also the installation and fixing structure.

[0030] Two square strips 120 are provided, and the two square strips 120 are fixed at intervals on the same side of the U-shaped frame 100; a guide groove 121 is provided on the inner side of the square strip 120 along the length direction of the square strip 120;

[0031] The sealing baffle 110 is slidably inserted into the guide groove 121 of the two square strips 120; the main function of the sealing baffle 110 is to adjust the ventilation and sealing of the greenhouse, and to "open" and "close" the ventilation holes on the U-shaped frame 100.

[0032] The rack 140 is fixed to the back of the sealing baffle 110; the gear 150 is fixed to the top of the U-shaped frame 100; the gear 150 meshes with the rack 140; the gear 150 meshes with the rack 140 through the rack, and in conjunction with the electric drive device, the sealing baffle can slide as needed to adjust the opening and closing degree of the vent.

[0033] The first motor 160 is fixed to the top of the U-shaped frame 100, and the main shaft of the first motor 160 is fixedly connected to the gear 150.

[0034] The method of using a ventilation device for a greenhouse provided in this embodiment of the utility model is as follows:

[0035] 1. The ventilation device of this utility model is fixed to the window opening of the greenhouse wall. The side of the U-shaped frame 100 is provided with mounting holes to facilitate the insertion of bolts for fixing.

[0036] 2. When ventilation is required, the first motor 160 works and drives the gear 150 to rotate, thereby driving the rack 140 to move, which in turn controls the up-and-down sliding of the sealing baffle 110; the sliding sealing baffle 110 can adjust the size of the ventilation holes in the greenhouse, thereby controlling the air circulation in the greenhouse.

[0037] 3. After the ventilation operation is completed, the first motor 160 rotates in the opposite direction, the sealing baffle 110 resets and seals the ventilation holes on the U-shaped frame 100; thereby ensuring the temperature of the greenhouse and preventing rainwater from entering the greenhouse through the ventilation holes on the U-shaped frame 100.

[0038] In this embodiment, a rainproof component and a driving mechanism are also included. The rainproof component includes multiple rotating shafts 171 that are rotatably connected vertically and vertically in the U-shaped frame 100, and a rainproof plate 170 fixed on the rotating shafts 171. The driving mechanism can synchronously drive the multiple rotating shafts 171 to rotate in order to adjust the rotation angle of the rainproof plate 170.

[0039] In this embodiment, the drive mechanism includes a connecting plate 181, a synchronizing rod 182, and a second motor 190;

[0040] Each shaft 171 has a connecting plate 181 fixedly connected to its end; the ends of the multiple connecting plates 181 are hinged to the synchronizing rod 182; the second motor 190 is fixed to one side of the U-shaped frame 100, and the main shaft of the second motor 190 is fixedly connected to one of the shafts 171.

[0041] It should be noted that during rainy or snowy weather, for various reasons, such as the sealing baffle 110 not being reset during greenhouse ventilation operations, or rain occurring temporarily while the sealing baffle 110 is in a normally open ventilation state, rainwater will enter the greenhouse through the ventilation holes on the U-shaped frame 100, causing leakage. To solve this problem, the aforementioned rainproof component and drive mechanism were designed.

[0042] The rain-proof component and drive mechanism set in the U-shaped frame 100 can effectively prevent rainwater from entering the greenhouse in the above-mentioned temporary accidental situations by adjusting the tilt angle of the rain-proof plate 170; at the same time, the second motor 190 drives the rotating shaft 171 to rotate, which can specifically adjust the rotation angle of the rain-proof plate 170 and flexibly adjust the ventilation of the greenhouse.

[0043] The ventilation device for a greenhouse provided by this utility model has the following beneficial effects: This utility model designs a ventilation device for a greenhouse, which not only solves the problem of rain leakage in traditional ventilation systems, but also flexibly adjusts the ventilation volume of the greenhouse to ensure a suitable environment inside the greenhouse. It is simple and convenient.

Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs.
