Description

Technical Field

[0001] This utility model relates to the technical field of air humidity monitoring equipment, specifically an air humidity monitoring instrument for environmental monitoring. Background Technology

[0002] An air humidity monitoring instrument is a device used to measure the moisture content in the air. It converts humidity into an electrical signal or numerical display through principles such as capacitance, resistance, or dew point. It is widely used in meteorology, agriculture, industry, and home environments to monitor and regulate air humidity in real time. Some intelligent models also have data storage, remote transmission, and linkage control functions.

[0003] Traditional air humidity monitoring instruments can only monitor the air humidity in their vicinity. If it is necessary to monitor the air at higher altitudes, the air humidity monitoring instrument must be installed at a high altitude, which is dangerous. In addition, if the air circulation is poor, it will lead to poor accuracy of humidity monitoring. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: an air humidity monitoring instrument for environmental monitoring, comprising a movable base, wherein a caster wheel is fixedly installed at the bottom of the movable base, an air absorption mechanism is provided at the top of the movable base, and a humidity measuring mechanism is provided at the top of the movable base.

[0006] The air absorption mechanism includes two support arms, which are fixedly installed on the top two sides of the movable base.

[0008] As a further preferred embodiment of this technical solution, a threaded rod is threadedly connected to one end of the top of the movable base. The threaded end of the threaded rod extends to the bottom of the movable base and is rotatably sleeved with a support base plate. A sliding rod is fixedly installed at the top end of the support base plate away from the threaded rod, and the sliding rod is slidably connected to the inner wall of the movable base.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 6 As shown, in this embodiment, an air humidity monitoring instrument for environmental monitoring includes a mobile base 1. A caster wheel 11 is fixedly installed at the bottom of the mobile base 1. An air absorption mechanism 2 and a humidity measuring mechanism 3 are both installed at the top of the mobile base 1. The air absorption mechanism 2 includes two support arms 21, which are respectively fixedly installed on both sides of the top of the mobile base 1. A connecting cylinder 22 is fixedly installed at the end of each support arm 21 away from the mobile base 1. The two support arms 21 are respectively fixedly connected to both sides of the connecting cylinder 22. A duct suction fan 23 is fixedly connected to the bottom of the connecting cylinder 22. A fixed pipe 24 is fixedly connected to the top of the connecting cylinder 22. A splicing pipe 25 is detachably connected to the top of the fixed pipe 24. The connector 26 is connected to the bottom of the splicing pipe 25 and the receiving pipe 26. The bottom of the splicing pipe 25 and the receiving pipe 26 are fixedly connected to the insertion pipe fitting 261. The outer wall of the insertion pipe fitting 261 is fixedly fitted with a rubber ring 262. Through the design of the insertion pipe fitting 261, the user can pull out the splicing pipe 25 from the top of the fixed pipe 24 and pull out the receiving pipe 26 from the top of the splicing pipe 25. Then, a suitable number of splicing pipes 25 can be installed between the fixed pipe 24 and the receiving pipe 26 by insertion, so as to realize the function of adjusting the overall height of the hollow disk 27 on the ground, avoiding the problem of poor safety when installing instruments at high altitudes. After the splicing pipe 25 is fully assembled, the rubber ring 262 can seal the connection. The universal wheel 11 makes it easy for the user to use this structure flexibly.

[0024] like Figure 2 , Figure 3 As shown, a hollow disc 27 is fixedly connected to the top of the receiving pipe 26, and a branch pipe 28 is fixedly connected to the outer wall of the hollow disc 27. An external threaded ring 281 is threadedly connected to the bottom of the branch pipe 28, and an air filter cartridge 282 located in the inner cavity of the branch pipe 28 is fixedly connected to the top of the external threaded ring 281. Through the design of the hollow disc 27 and the branch pipe 28, air can be absorbed from six evenly distributed positions, improving the randomness of air extraction and increasing the monitoring effect of air humidity. Through the design of the air filter cartridge 282, impurities inside the air can be blocked, ensuring the smooth flow of the pipeline and the safety of the pipeline suction fan 23. The air filter cartridge 282 is located in the inner cavity of the branch pipe 28, giving it rainproof capability. During maintenance, the external threaded ring 281 is rotated at the bottom of the branch pipe 28, and the air filter cartridge 282 can be removed for easy cleaning by the user.

[0025] like Figure 3 As shown, a threaded rod 12 is threadedly connected to one end of the top of the movable base 1. The threaded end of the threaded rod 12 extends to the bottom of the movable base 1 and is rotatably sleeved with a support base plate 13. A sliding rod 14 is fixedly installed at the top end of the support base plate 13 away from the threaded rod 12. The sliding rod 14 is slidably connected to the inner wall of the movable base 1. After the structure is moved into place, the threaded rod 12 can be manually rotated, and the support base plate 13 is slidably connected to the movable base 1 by means of the sliding rod 14. At this time, the support base plate 13 can be displaced relative to the movable base 1, thereby providing stable support for the structure by means of the support base plate 13.

[0026] like Figure 5 , Figure 6 As shown, the humidity measuring mechanism 3 includes a protective chamber 31, which is fixedly installed on the top of the movable base 1. A sealed inspection door is rotatably connected to the front of the protective chamber 31. The protective chamber 31 is fixedly connected to the bottom of the duct suction fan 23. A mesh partition 32 is fixedly installed on the inner wall of the protective chamber 31. An air humidity monitoring instrument body 33 is fixedly installed on the top of the mesh partition 32. A storage battery 34 is fixedly installed on the bottom of the inner wall of the protective chamber 31. The air sampled by the duct suction fan 23 is delivered to the inner cavity of the protective chamber 31. The air then flows through the surface of the air humidity monitoring instrument body 33 to monitor the humidity. The storage battery 34 is used to power the air humidity monitoring instrument body 33 and the duct suction fan 23, making this structure flexible and reusable.

[0027] like Figure 5 , Figure 6As shown, both sides of the protective chamber 31 are provided with strip-shaped grooves, and both sides of the protective chamber 31 are fixedly connected to the exhaust chamber 35. An elastic rope 351 is fixedly installed on the top of the inner wall of the exhaust chamber 35, and a sealing frame 352 is fixedly connected to the bottom of the elastic rope 351. The sealing frame 352 is movably inserted into the bottom of the exhaust chamber 35, and a notch 353 is provided on the top of the sealing frame 352. When the duct suction fan 23 is working, gas will enter the interior of the protective chamber 31, causing the air pressure inside the protective chamber 31 to increase. The air pressure will push the sealing frame 352 and stretch the elastic rope 351, so that the gas inside the protective chamber 31 will be discharged from the notch 353. When the duct suction fan 23 is turned off, the air pressure will disappear. Through the elasticity of the elastic rope 351, the sealing frame 352 can be driven to reset and seal the bottom of the exhaust chamber 35, so as to prevent dust from entering when idle.

[0028] This utility model provides an air humidity monitoring instrument for environmental monitoring. The specific working principle is as follows: Before use, the structure is moved to the measurement point, and then the threaded rod 12 is manually rotated to drive the support base plate 13 to move down. The support base plate 13 provides stable support for the structure. Then, a suitable number of splicing pipes 25 are installed between the fixed pipe 24 and the receiving pipe 26 through a plug-in assembly method. The overall height of the hollow plate 27 is designed. During use, the pipe suction fan 23 is controlled to work, drawing air from the end of the branch pipe 28 and then delivering it to the inner cavity of the protective chamber 31. The air then flows through the surface of the air humidity monitoring instrument body 33 for humidity monitoring.
