DETAILED DESCRIPTION

[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some of the embodiments of the present application but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0026] As shown in Figures 1 to 7 The greenhouse temperature and humidity monitoring device provided by the present application comprises a temperature and humidity detector 1, a connecting frame 11 is fixedly installed at the bottom of the temperature and humidity detector 1, and a monitoring probe 12 is fixedly installed at the inner side of the connecting frame 11.

[0027] A connecting head 2 is threadedly sleeved at the bottom of the connecting frame 11, a knob 21 is fixedly installed at the bottom of the connecting head 2, a clamping groove 22 is formed at the bottom of the knob 21, a first clamping block 23 is fixedly installed in the clamping groove 22, a movable groove 24 is formed in the knob 21 and below the clamping groove 22, a dustproof cylinder 3 is arranged at the bottom of the knob 21, a convex edge 32 is fixedly installed on the outer wall above the dustproof cylinder 3, the convex edge 32 is movably installed in the movable groove 24, a second clamping block 31 is fixedly installed at the top of the dustproof cylinder 3, the convex edge 32 and the movable groove 24 are elastically connected through a spring 33, and the opposite ends of the second clamping block 31 and the first clamping block 23 are both provided with one-way teeth, and the teeth of the second clamping block 31 and the first clamping block 23 are arranged in opposite directions.

[0028] When it is necessary to monitor the temperature and humidity inside the greenhouse, the staff first installs the temperature and humidity detector 1 at a suitable position, and then powers on the temperature and humidity detector 1. After the temperature and humidity detector 1 is powered on, the temperature and humidity inside the greenhouse are continuously monitored through the monitoring probe 12. During long-time monitoring, the dustproof cylinder 3 is arranged to block the dust generated by the staff during farmland operation, so that the dust is accumulated on the surface of the dustproof cylinder 3. Through the external design of the dustproof cylinder 3, the staff can easily observe the state of the dustproof cylinder 3 during daily inspection. When there is a lot of dust and impurities on the dustproof cylinder 3, the staff can unscrew the knob 21 to remove the connecting head 2 from the connecting frame 11. After removal, the staff can fix the knob 21 with one hand, and rotate (for example, clockwise) the dustproof cylinder 3 with the other hand, so that the dust and impurities on the dustproof cylinder 3 are removed. Figure 5As shown, when the worker rotates the dustproof cylinder 3 clockwise, the top teeth of the second clamping block 31 will be in close contact with the bottom teeth of the first clamping block 23, causing the dustproof cylinder 3 to move downward. When the second clamping block 31 moves to the lowermost position of the teeth of the first clamping block 23, the worker rotates the dustproof cylinder 3 again, and the convex edge 32 will be reset upward by the elastic potential of the spring 33, causing the second clamping block 31 and the first clamping block 23 to be in close contact with each other. Through this rapid fitting motion, the dustproof cylinder 3 will intermittently vibrate when the worker rotates it, causing the dust on its surface to be quickly shaken off. At the same time, the worker can also quickly clean the dustproof cylinder 3 by washing or blowing.

[0029] Through the external design of the dustproof cylinder 3, the worker can quickly observe it when there is a lot of dust. Through the transmission characteristics of the one-way teeth, the connecting frame connector 2 is fixed, and the dustproof cylinder 3 can only rotate in one direction through the second clamping block 31. When rotating, the convex edge 32 will move downward along the slope of the bottom teeth of the first clamping block 23. Through the clockwise rotation of the dustproof cylinder 3, the dustproof cylinder 3 will gradually move downward during rotation, and after reaching the threshold, the dustproof cylinder 3 will be reset by the elastic potential of the spring 33, and the impact force generated by the reset will cause the dust on the dustproof cylinder 3 to fall off. Compared with traditional devices, this device is easy to install and disassemble, and the worker can quickly clean the dust by rotating the dustproof cylinder 3, improving the maintenance efficiency of the worker and ensuring the service life of the monitoring probe 12.

[0030] The top end face of the second clamping block 31 is in close contact with the bottom end face of the first clamping block 23, and the second clamping block 31 can rotate clockwise or counterclockwise along the bottom end face of the first clamping block 23.

[0031] When the tooth opening direction of the second clamping block 31 and the first clamping block 23 changes, the second clamping block 31 can rotate clockwise or counterclockwise.

[0032] The front outer wall of the dustproof cylinder 3 is provided with a pointing arrow 34, which is used to guide the rotation direction of the dustproof cylinder 3.

[0033] The setting of the pointing arrow 34 can ensure that the worker can correctly rotate the dustproof cylinder 3 during the dust cleaning operation, avoiding excessive force that may cause damage.

[0034] The upper and lower ends of the rear side of the temperature and humidity detector 1 are provided with mounting mechanisms 4, the mounting mechanism 4 comprises a first clamping plate 41 and a second clamping plate 44 rotatably mounted on the rear side of the temperature and humidity detector 1, the first clamping plate 41 and the second clamping plate 44 are mirror image arranged, a fixed plate 45 is fixedly installed at one end of the second clamping plate 44 away from the temperature and humidity detector 1, and an expansion slot 43 is formed in the interior of one end of the first clamping plate 41 away from the temperature and humidity detector 1.

[0035] One end of the first clamping plate 41 and one end of the second clamping plate 44 are rotatably mounted on the rear side of the working temperature and humidity detector 1, and can be rotated. When the temperature and humidity detector 1 needs to be installed, the staff can use one hand to paste one end of the first clamping plate 41 away from the temperature and humidity detector 1 on the fixed column, and then use the other hand to hold the second clamping plate 44, and insert the fixed plate 45 into the interior of the expansion slot 43 to realize the connection of the first clamping plate 41 and the second clamping plate 44. The staff can ensure that the first clamping plate 41 and the second clamping plate 44 are stably fixed on the column by controlling the depth of the fixed plate 45 inserted.

[0036] The outer wall of the first clamping plate 41 is fixedly installed with a fixed boss 42, the interior of the fixed boss 42 is screw-mounted with a bolt 47, one end of the bolt 47 is fixedly installed with a fixed head 48, and one end of the fixed head 48 penetrates into the interior of the expansion slot 43.

[0037] After the fixed plate 45 is inserted into the interior of the expansion slot 43, the staff rotates the bolt 47, the rotation of the bolt 47 drives the fixed head 48 to displace towards the interior of the expansion slot 43, and finally makes the fixed head 48 and the fixed plate 45 abut each other, and the fixing is completed.

[0038] The surface of the fixed plate 45 towards the fixed head 48 is provided with a friction pad 46, the fixed head 48 and the friction pad 46 abut each other, and the fixed head 48 and the friction pad 46 are fixed through the friction force therebetween.

[0039] The friction force between the fixed head 48 and the friction pad 46 is large and not easy to loosen through the friction force of the fixed head 48 based on the friction pad 46 and the material characteristics of the friction pad 46.

[0040] The two groups of clamping plates fix the temperature and humidity detector 1 on the column for installation by inserting the fixed plate 45 into the interior of the expansion slot 43, and then the fixed head 48 and the friction pad 46 fix the fixed plate 45 through the friction force by rotating the bolt 47, compared with the traditional device, the mounting mechanism 4 of the device is convenient to adjust, can be quickly installed in most of the greenhouses, has strong applicability, and meets the installation needs of users.

[0041] The temperature and humidity detector 1 has a display screen 13 on its front side. The display screen 13 can be used to show the temperature and / or humidity detected by the temperature and humidity detector 1 to the staff.

[0042] Below the display screen 13 is a control button 14, which can be used to control whether the temperature and humidity detector 1 starts working.

[0043] The working principle and usage process of this application:

[0044] When temperature and humidity monitoring is required inside the greenhouse, the staff first installs the temperature and humidity detector 1 in a suitable location, then powers it on. After powering on, the detector continuously monitors the temperature and humidity inside the greenhouse through the monitoring probe 12. During long-term monitoring, the dust cover 3 prevents dust generated by the staff during farm work from accumulating on its surface. The external design of the dust cover 3 ensures that the staff can easily observe its condition during routine inspections. When there is a lot of dust and impurities on the dust cover 3, the staff can manually turn the knob 21 to remove the connector 2 from the connector frame 11. After removal, the staff can hold the knob 21 in place with one hand and rotate the dust cover 3 clockwise with the other hand. Figure 5 As shown, when the worker rotates the dust cover 3 clockwise, the top teeth of the second locking block 31 engage with the bottom teeth of the first locking block 23, causing the dust cover 3 to move downwards. When the second locking block 31 moves to the bottom of the teeth of the first locking block 23, the worker can rotate the dust cover 3 again, and the protruding edge 32 will return to its original position upwards through the elastic potential energy of the spring 33, causing the second locking block 31 and the first locking block 23 to engage with each other. Through this rapid engagement movement, the dust cover 3 will shake intermittently when the worker rotates it, causing the dust on its surface to fall off quickly. At the same time, the worker can also quickly clean the dust cover 3 by washing it with water or blowing it with air.
