[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 As shown, a portable atmospheric VOCs monitoring device includes a monitoring body 1, and further includes: a tray 2 located at the lower part of the monitoring body 1; a support rod 3 rotatably connected to the tray 2; a pulley assembly 4 fixedly connected to the support rod 3; telescopic legs 5 fixedly connected to the side wall of the support rod 3; and a connecting rod 6 connecting adjacent telescopic legs 5.

[0025] The monitoring instrument 1 is used to monitor and display volatile organic compounds in the atmosphere. The monitoring instrument 1 is an instrument that can be directly purchased from the existing market.

[0026] The tray 2 has a recess in the middle, into which the monitor body 1 can be placed, thus preventing the monitor body 1 from sliding off the tray 2. When the tray 2 moves, it moves the monitor body 1 along with it. The tray 2 has clamping plates 21 on both sides, with the height of the clamping plates 21 being the same as the height of the monitor body 1. The clamping plates 21 are made of a material with a certain degree of toughness, such as acrylic sheet. The top of the clamping plate 21 has a bent part 22, the bottom of which fits against the top of the monitor body 1. The two clamping plates 21 clamp the sides of the monitor body 1, further restricting its position and preventing it from falling off when the tray 2 moves.

[0027] Support rod 3 is connected to the side wall of tray 2 via pivot 31. A support rod 3 is fixed to each end of pivot 31, and pivot 31 is rotatably connected to tray 2. Two adjacent support rods 3 along the long side of the monitor body 1 rotate synchronously. When the monitor body 1 needs to be moved, the free ends of the support rods 3 away from pivot 31 are retracted upwards to reduce the overall height of the device. When the device needs to be fixed, the free ends of the support rods 3 are rotated downwards to support and fix the monitor body 1 at a high position.

[0028] like Figure 3As shown, a spring 11 is provided on the side of the monitor body 1. One end of the spring 11 is fixed to the monitor body 1, and a positioning hook 12 is provided at the end of the spring 11. A positioning hole 32 is provided at the free end of the support rod 3, through which the positioning hook 12 can pass. When the free end of the support rod 3 is facing upward, the positioning hook 12 can hook the positioning hole 32. In use, after the support rod 3 is facing upward, the positioning hook 12 and the spring 11 are stretched, and then the positioning hook 12 passes through the positioning hole 32. At this time, the spring 11 is in a stretched state, thereby driving the support rod 3 to move closer to the monitor body 1, restricting the outward rotation of the support rod 3, and keeping the support rod 3 stable in the retracted state. When it is necessary to unfold the support rod 3, the spring 11 and the positioning hook 12 can be pulled out of the positioning hole 32 by hand.

[0029] The pulley assembly 4 includes a connecting plate 41 and a roller 42. The connecting plate 41 is vertically fixed to the support rod 3, and the roller 42 is rotatably connected to the connecting plate 41. The roller 42 is located at the front end of the connecting plate 41, and the bottom surface of the roller 42 protrudes from the support rod 3. When the free end of the support rod 3 is facing upward, the roller 42 is in contact with the ground, at which time the roller 42 supports the device. When in the storage state, the roller 42 facilitates the movement of the device in the VOCs emission monitoring plant. In cases where multiple monitoring locations need to be moved, moving the device directly using the roller 42 within the plant is more convenient than pulling the monitoring device with a car within the plant. Furthermore, the roller 42 allows for more effortless movement of the device, enabling rapid movement to the next monitoring location after monitoring at one location is completed.

[0030] When conducting long-term, fixed-point monitoring outdoors, the support pole 3 is rotated downwards and unfolded, thereby elevating the monitoring device 1 into the air. This prevents damage to the monitoring device 1 due to water accumulation or other reasons. Furthermore, being elevated also makes it more easily visible, reducing the possibility of damage going unnoticed by pedestrians or vehicles. Figure 4 As shown, the bottom of the tray 2 is provided with a limiting plate 23. There are two limiting plates 23. The limiting plates 23 are located on the inner side of the tray 2. The limiting plates 23 are used to limit the rotation angle of the support rod 3. The end of the limiting plate 23 faces downward. The limiting plates 23 are inclined on the tray 2 with an included angle of 60 degrees. When the support rod 3 drives the connecting plate 41 to rotate together, the limiting plate 23 can contact the connecting plate 41. At this time, the limiting plate 23 prevents the support rod 3 from continuing to rotate. A positioning pin 7 can be inserted into the limiting plate 23 and the connecting plate 41. After the positioning pin 7 is inserted, it also restricts the upward rotation of the support rod 3, so that the angle of the support rod 3 is fixed.

[0031] When the support rod 3 rotates, the telescopic outrigger 5 rotates together. After the support rod 3 is fixed in position, the telescopic outrigger 5 supports the ground. The telescopic outrigger 5 can adjust the height of the monitoring instrument body 1. The telescopic outrigger 5 includes a fixed slide rail 51 and a slide rod 52. The fixed slide rail 51 is fixed to the side wall of the support rod 3. The end of the slide rod 52 is a pointed tip. The end of the slide rod 52 can support the ground. In the soil, the end of the slide rod 52 can be inserted into the soil. The slide rod 52 is slidably connected to the fixed slide rail 51, and the fixed slide rail 51 restricts the movement direction of the slide rod 52.

[0032] The side wall of the fixed slide rail 51 is provided with a fastening plate 53, which is C-shaped. One end of the fastening plate 53 is fixed to the side wall of the fixed slide rail 51 by a rivet, and the other end of the fastening plate 53 is screwed with a limit bolt 54. The side wall of the limit bolt 54 is provided with a rotating handle, and the end of the limit bolt 54 contacts the side wall of the fixed slide rail 51. When it is necessary to restrict the sliding of the slide rod 52, the limit bolt 54 is turned to compress the fixed slide rail 51, thereby increasing the friction between the fixed slide rail 51 and the slide rod 52, making the slide unable to slide. This can be referred to as the telescopic fixing method of a measuring tripod.

[0033] The end of the connecting rod 6 is fixed to the fastening plate 53. The connecting rod 6 is provided with a handle 61. The connecting rod 6 further causes the two support rods 3 to rotate synchronously. When the support rods 3 are facing upward, the handle 61 is also facing upward. At this time, it is convenient to pull the handle 61 to move the device in the storage state.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
