When the length of the connecting line 4 is adjusted, the connecting block 6 will move with the connecting line 4, so that the position of the temperature and humidity sensor 8 on the connecting line 4 changes, and then the temperature and humidity at different heights are monitored. When the temperature and humidity are abnormal, these data are collected by the sensor and transmitted to the cloud, and alarm notifications are sent via SMS, email and application notifications. By adjusting the position of the temperature and humidity sensor 8, the temperature and humidity at different heights can be detected to ensure the accuracy of the temperature and humidity detection, thereby providing a better environment for plant growth.

[0031] A slide groove 9 is provided in the connecting block 6, and a connecting rod 10 is sealingly and slidably connected to the side wall of the connecting block 6. One end of the connecting rod 10 close to the connecting block 6 is located in the slide groove 9, and one end of the connecting rod 10 away from the slide groove 9 is fixedly connected to a connecting plate 11 located on the bottom surface of the connecting block 6, and a sponge block 16 is fixedly connected to the top surface of the connecting plate 11. A driving mechanism for driving the connecting rod 10 to move is provided on the connecting block 6;

[0032] When plants are growing in a greenhouse, the temperature difference between morning and evening will cause water to appear on the temperature and humidity sensor 8. The water at this time will affect the detection accuracy of the temperature and humidity sensor 8. The present application can drive the connecting rod 10 to move through a driving mechanism.

[0033] The driving mechanism includes a connecting groove 13 provided on the top surface of the connecting block 6, the connecting groove 13 is communicated with the slide groove 9, a piston 15 is fixedly connected to the surface of the connecting rod 10 and is sealed and slidably connected to the slide groove 9, a first spring is fixedly connected between the side of the piston 15 close to the connecting groove 13 and the slide groove 9, an air outlet mechanism is provided in the slide groove 9, a slider 14 is sealed and slidably connected in the connecting groove 13, a pair of rectangular plates 25 are fixedly connected to the side wall of the slider 14, a second spring is fixedly connected between the bottom surface of the rectangular plate 25 and the connecting block 6, and a baffle 24 aligned with the slider 14 is fixedly connected to the support plate 2;

[0034] When it is necessary to wipe the moisture on the temperature and humidity sensor 8, the shaft 3 is driven to rotate, and the connecting wire 4 pulls the connecting block 6 to move upward, thereby driving the baffle 24 to contact the slider 14, and then the baffle 24 will push the slider 14, so that the gas in the connecting groove 13 enters the slide groove 9, and the gas will push the piston 15. At this time, the gas on the side of the piston 15 away from the slider 14 will be discharged from the air outlet mechanism, and the piston 15 will drive one end of the connecting rod 10, so that the connecting plate 11 drives the sponge block 16 to wipe the moisture on the temperature and humidity sensor 8, thereby achieving the effect of automatically cleaning the moisture of the temperature and humidity sensor 8.

[0035] The air outlet mechanism includes a plurality of air outlet holes 17 provided on the top surface of the connecting plate 11. The interior of the connecting plate 11 is a hollow structure, and the interior of the connecting rod 10 is a hollow structure. When the piston 15 moves, the gas in the slide groove 9 will enter the hollow connecting rod 10 under the push of the piston 15, and then enter the connecting plate 11, and finally be discharged from the air outlet holes 17 to the sponge block 16, so as to achieve the effect of air-drying the sponge block 16. At the same time, the gas can also pass through the sponge block 16 to reach the temperature and humidity sensor 8 to air-dry the temperature and humidity sensor 8. By controlling the connection block 6 to move up and down, the connecting plate 11 can repeatedly push the slider 14, so that the piston 15 can move repeatedly under the action of the gas, so that the gas in the slide groove 9 can repeatedly enter the connecting plate 11, so as to achieve the effect of continuously drying the sponge block 16 and the temperature and humidity sensor 8.

[0036] A hollow block 18 is sealed and slidably connected inside the connecting plate 11, and an air inlet groove is provided on the side of the hollow block 18 close to the connecting rod 10, and an air outlet groove is provided on the side of the connecting plate 11 away from the connecting rod 10. A connecting hole corresponding to the air outlet 17 is provided on the top surface of the connecting plate 11, and a third spring is fixedly connected between the side of the hollow block 18 away from the connecting rod 10 and the inner wall of the connecting plate 11; in the present application, when the gas enters the connecting plate 11 from the connecting rod 10, it will first enter the hollow block 18 from the air inlet groove, and then the gas will push the hollow block 18, and when the connecting hole is aligned with the air outlet 17, the gas will be discharged from the air outlet 17 at the same time and evenly, so as to improve the effect of air-drying the sponge block 16 and the temperature and humidity sensor 8.

[0037] The top surface of the connecting block 6 is fixedly connected with an alarm 23, the top surface of the temperature and humidity sensor 8 is fixedly connected with a first contact 21, the top surface of the mounting groove 12 is fixedly connected with a second contact 22 corresponding to the second contact 22, and the alarm 23 can be activated when the first contact 21 contacts the second contact 22, the temperature and humidity sensor 8 is fixedly connected with a first magnetic block 19 on one side close to the sliding rod, the connecting rod 10 is fixedly connected with a second magnetic block 20 that repels the first magnetic block 19, and a fourth spring is fixedly connected between the top surface of the temperature and humidity sensor 8 and the inner wall of the mounting groove 12;

[0038] In the present application, under normal circumstances, the baffle 24 pushes the slider 14 to move to such an extent that the slide bar cannot drive the second magnetic block 20 to move below the first magnetic block 19. When abnormal temperature and humidity are detected, the motor 5 will automatically drive the shaft 3 to rotate, so that the baffle 24 can completely push the slider 14, allowing the gas in the connecting groove 13 to completely enter the slide groove 9. At this time, the piston 15 will drive the second magnetic block 20 on the connecting rod 10 to move below the first magnetic block 19. At this time, the second magnetic block 20 will push the first magnetic block 19, causing the temperature and humidity sensor 8 to move upward, thereby allowing the first contact 21 to contact the second contact 22 to activate the alarm 23. At this time, the alarm 23 will sound and light alarms, thereby alerting the surrounding staff.

[0039] Red gas is stored in the installation groove 12, and the temperature and humidity sensor 8 is sealed and slidably connected to the inner wall of the installation groove 12. The side wall of the connecting block 6 is provided with a discharge groove 26 connected to the installation groove 12, and a sealing mechanism is arranged in the discharge groove 26; when the temperature and humidity sensor 8 moves upward, the red gas in the installation groove 12 is pushed. At this time, the sealing mechanism is opened, and the red gas can be discharged from the discharge groove 26. The red gas will diffuse in the air, thereby improving the warning effect.

[0040] Embodiment 2: Figure 6 to Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the sealing mechanism includes a sealing block 27 that is sealed and slidable with the discharge groove 26, the inner wall of the discharge groove 26 is fixedly connected with a guide rod 28, the sealing block 27 is sealed and slidably connected with the guide rod 28, and an elastic rope 29 is fixedly connected between the side of the sealing block 27 close to the mounting groove 12 and the inner wall of the discharge groove 26; the red gas will enter the discharge groove 26 under the push of the temperature and humidity sensor 8, and the gas will push the sealing block 27 at this time, so that the sealing block 27 no longer seals the discharge groove 26, and the red gas can be discharged from the discharge groove 26 at this time, and after the gas is discharged, the sealing block 27 can slide on the guide rod 28 under the pull of the elastic rope 29 to complete the reset.

[0041] The temperature and humidity sensor 8 is rotatably connected to a hollow arc plate 31 on one side away from the connecting rod 10, and a hollow elastic block 30 is fixedly connected between the top surface of the arc plate 31 and the connecting block 6, and the elastic block 30 is connected to the inside of the arc plate 31; in the present application, when the sponge block 16 moves to the arc block, the sponge block 16 will push the arc block, and at this time the arc block will squeeze the elastic block 30, so that the gas in the elastic block 30 enters the arc plate 31, and finally sprays onto the sponge block 16 from the spray hole, thereby blowing away impurities on the sponge block 16, and at the same time, the arc plate 31 can also scrape off impurities on the sponge block 16 to improve the wiping effect of the sponge block 16 on the temperature and humidity sensor 8.

[0042] Working principle: This application observes the growth of plants through the monitor 7, and the temperature and humidity sensor 8 can monitor the temperature and humidity around the plants. The motor 5 drives the shaft 3 to rotate forward or reverse. The forward and reverse rotation of the shaft 3 can control the length of the connecting line 4. When the length of the connecting line 4 is adjusted, the connecting block 6 will move with the connecting line 4, so that the position of the temperature and humidity sensor 8 on the connecting line 4 changes, and then the temperature and humidity at different heights are monitored. When the temperature and humidity are abnormal, these data are collected by the sensor and transmitted to the cloud, and alarm notifications are sent through SMS, emails and application notifications. By adjusting the position of the temperature and humidity sensor 8, The temperature and humidity at different heights can be detected to ensure the accuracy of the temperature and humidity detection, thereby providing a better environment for plant growth; when plants grow in a greenhouse, the temperature and humidity sensor 8 will be covered with water due to the temperature difference between morning and evening, and the water at this time will affect the detection accuracy of the temperature and humidity sensor 8. The present application can drive the connecting rod 10 to move through the driving mechanism, and the connecting rod 10 will drive the connecting plate 11 to move, so that the sponge block 16 can wipe and dry the moisture on the temperature and humidity sensor 8, and at the same time, the impurities on the temperature and humidity sensor 8 can be scraped off, thereby improving the accuracy of the temperature and humidity sensor 8 in detecting temperature and humidity;

[0043] When it is necessary to wipe the moisture on the temperature and humidity sensor 8, the connecting wire 4 is driven to pull the connecting block 6 upward by rotating the driving shaft 3, thereby driving the baffle 24 to contact the slider 14, and then the baffle 24 will push the slider 14, so that the gas in the connecting groove 13 enters the slide groove 9, and the gas will push the piston 15. At this time, the gas on the side of the piston 15 away from the slider 14 will be discharged from the air outlet mechanism, and the piston 15 will drive the connecting rod 10 to one end, so that the connecting plate 11 drives the sponge block 16 to wipe the moisture on the temperature and humidity sensor 8, thereby achieving the effect of automatically cleaning the moisture on the temperature and humidity sensor 8; when the piston 15 moves, the slider The gas in the groove 9 will enter the hollow connecting rod 10 under the push of the piston 15, and then enter the connecting plate 11, and finally be discharged from the air outlet 17 to the sponge block 16, so as to achieve the effect of air drying the sponge block 16. At the same time, the gas can also pass through the sponge block 16 to reach the temperature and humidity sensor 8 to air dry the temperature and humidity sensor 8. By controlling the connection block 6 to move up and down, the connecting plate 11 can repeatedly push the slider 14, so that the piston 15 can move repeatedly under the action of the gas, so that the gas in the slide groove 9 can repeatedly enter the connecting plate 11, so as to achieve the effect of continuously drying the sponge block 16 and the temperature and humidity sensor 8.

[0044] In the present application, when the gas enters the connecting plate 11 from the connecting rod 10, it will first enter the hollow block 18 from the air inlet groove, and then the gas will push the hollow block 18. When the connecting hole is aligned with the air outlet hole 17, the gas will be discharged from the air outlet hole 17 at the same time and evenly to improve the effect of air drying the sponge block 16 and the temperature and humidity sensor 8. In the present application, under normal circumstances, the baffle 24 pushes the slider 14 to move to such an extent that the slider cannot drive the second magnetic block 20 to move below the first magnetic block 19. When the temperature and humidity are detected to be abnormal, the motor 5 will automatically drive the shaft 3 to rotate, so that the baffle 24 completely pushes the slider 14, so that the connecting groove 1 3 completely enters the slide groove 9, at this time, the piston 15 will drive the second magnetic block 20 on the connecting rod 10 to move below the first magnetic block 19, at this time, the second magnetic block 20 will push the first magnetic block 19, so that the temperature and humidity sensor 8 moves upward, so that the first contact 21 and the second contact 22 are in contact to start the alarm 23, and the alarm 23 will sound and light alarm, thereby alerting the surrounding staff; when the temperature and humidity sensor 8 moves upward, the present application will push the red gas in the installation groove 12, and at this time, the sealing mechanism will be opened, and the red gas can be discharged from the discharge groove 26, and the red gas will diffuse in the air, thereby improving the warning effect.
