[0002] In agricultural production, greenhouses play a crucial role, providing crops with a suitable growing environment unaffected by seasons and climate. However, the gaseous environment inside the greenhouse directly impacts crop growth, including concentrations of carbon dioxide, oxygen, and harmful gases. Therefore, real-time monitoring of the gaseous environment within the greenhouse is essential.

[0003] Most existing agricultural greenhouse gas environment monitoring devices are fixedly installed inside the greenhouse, making it difficult to adjust them flexibly according to different planting areas or different crop varieties. They cannot comprehensively and accurately monitor the gas environment in various areas of the greenhouse.

[0004] Therefore, an agricultural greenhouse gas environment monitoring device has been developed that allows for flexible adjustment of the monitor's position to adapt to environmental monitoring needs under different conditions and improve monitoring accuracy. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] An agricultural greenhouse gas environment monitoring device, such as Figures 1-3 As shown, the system includes a greenhouse 1, a support frame 2, a motor 3, a lead screw 4, a first sliding frame 5, a monitoring instrument 6, a limiting frame 7, a telescopic spring 8, a rodless cylinder 9, a second sliding frame 10, an air intake 11, an air inlet 12, and a screw sleeve 18. The support frame 2 is connected to the top of the greenhouse 1. The motor 3 is connected to the left side of the support frame 2. A lead screw 4 is rotatably connected to the support frame 2 and is connected to the output shaft of the motor 3. The first sliding frame 5 is threaded onto the lead screw 4. The monitoring instrument 6 is placed in front of the first sliding frame 5, and the monitoring instrument 6 is placed behind the first sliding frame 5. A rodless cylinder 9 is connected to the slider of the rodless cylinder 9. A second sliding frame 10 is connected to the second sliding frame 10. An air intake 11 is connected to the second sliding frame 10. A filter screen is provided on the air intake 11. The air intake 11 has a horn-shaped structure. An air inlet pipe 12 is connected to the upper side of the air intake 11. A screw sleeve 18 is connected to the air inlet pipe 12. The screw sleeve 18 is threadedly connected to the monitor 6. A limiting frame 7 is slidably connected to the front left side of the first sliding frame 5. Two telescopic springs 8 are connected between the limiting frame 7 and the first sliding frame 5. The limiting frame 7 is snapped into the monitor 6.

[0023] When using this utility model, first place the device in the usage area of ​​greenhouse 1, then pull the limiting frame 7 to slide out on the first sliding frame 5. The telescopic spring 8 is compressed and contracted. Then place the monitor 6 on the first sliding frame 5 and release the limiting frame 7. The telescopic spring 8 rebounds, causing the limiting frame 7 to reset and engage with the monitor 6, thus fixing the monitor 6. After the monitor 6 is fixed, tighten the screw sleeve 18 on the monitor 6 so that the air intake 11 is connected to the monitor 6. This allows the monitor 6 to draw in the gas in greenhouse 1 through the air intake 11 and the air inlet pipe 12 for detection, thereby monitoring the gas environment in greenhouse 1. This facilitates the installation and maintenance of the monitor 6. During the process of drawing in air through the air intake 11, the filter screen on the air intake 11 can filter out impurities in greenhouse 1. Ground blockage can damage the monitor 6.

[0024] like Figures 4-5 As shown, it also includes a rack 13, a common gear 14, a transmission assembly 15, a bevel gear set 16, and a scraper 17. The rack 13 is connected to the left side of the rodless cylinder 9. The common gear 14 is rotatably connected to the left rear part of the second sliding frame 10. The common gear 14 meshes with the rack 13. A transmission shaft is provided on the air intake 11. The transmission assembly 15 is connected between the transmission shaft and the common gear 14. The scraper 17 is rotatably connected to the air intake 11. The bevel gear set 16 is connected between the scraper 17 and the transmission shaft. The transmission assembly 15 includes a flat belt and a pulley. The pulley is connected to the left side of the common gear 14. The pulley is also connected to the left side of the transmission shaft. A flat belt is wound around the pulleys.

[0025] When the position of the monitor 6 needs to be adjusted, the motor 3 on the support frame 2 can be started, causing the lead screw 4 to rotate. Under the action of the thread, the first sliding frame 5 slides, adjusting the horizontal position of the monitor 6 and the air intake 11. At the same time, the rodless cylinder 9 can be started, causing the second sliding frame 10 to move, adjusting the sampling height of the air intake 11. This facilitates flexible adjustment of the position of the monitor 6, adapting to environmental monitoring needs under different conditions and improving monitoring accuracy. During the sliding movement of the second sliding frame 10, the ordinary gear 14 is driven to move, causing the ordinary gear 14 to rotate. Through the transmission action of the flat belt and pulley in the transmission assembly 15, the transmission shaft rotates. Then, through the meshing motion of the bevel gear set 16, the scraper 17 rotates, which can clean the filter screen of the air intake 11 and prevent the filter screen from clogging.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
