[0026] Figure 1 to Figure 6 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 6 The utility model is further described.

[0027] A chemical waste gas detection device includes a base 1, and also includes a fixed rod 2, a lifting rod 3, a lifting assembly 4, a detector body 5, a socket 6, a plug 7 and a limit assembly 8.

[0028] The specific model of the detector body 5 is the Dräger Pir7000-RTO exhaust gas LEL sampling monitoring system device.

[0029] Specifically, the lifting assembly 4 includes a threaded rod 401, the threaded rod 401 is rotatably installed inside the fixed rod 2, the outer side of the threaded rod 401 is threadedly connected to the lifting frame 402, the top of the lifting frame 402 is fixedly installed with a connecting rod 403, two connecting rods 403 are arranged side by side, and the detector body 5 is fixedly installed on the top of the two connecting rods 403.

[0030] In this embodiment, when the threaded rod 401 rotates, the lifting frame 402 will move up and down due to the interaction between the external thread of the threaded rod 401 and the internal thread of the lifting frame 402, thereby driving the connecting rod 403 and the detector body 5 to move up and down together.

[0031] Specifically, a limiting rod 404 is fixedly installed inside the fixing rod 2 , and a lifting frame 402 is slidably connected to the outer side of the limiting rod 404 .

[0032] In this embodiment, the lifting frame 402 can slide on the surface of the limiting rod 404, and the limiting rod 404 has a limiting effect on the lifting frame 402, so that the lifting frame 402 can move more smoothly.

[0033] Specifically, a bevel gear 405 is fixedly installed on the top of the threaded rod 401, and a bevel gear 406 is meshed on the surface of the bevel gear 405. A rotating wheel 407 is fixedly installed on the outer side of the bevel gear 406. A fixing frame 408 is fixedly installed on the side of the rotating wheel 407. A limiting hole 409 is provided inside the fixing frame 408. A limiting hole 410 matched with the limiting hole 409 is provided on the side of the fixing rod 2. The number of the limiting holes 410 is 24, and the 24 limiting holes 410 are equally divided on the outer side of the rotating wheel 407.

[0034] In this embodiment, rotating wheel 407 can drive bevel gear 2 406 to rotate. Under the meshing transmission of the bevel gears, bevel gear 1 405 can drive threaded rod 401 to rotate. Moreover, by clamping the limiting plug rod in limiting hole 1 409 and the corresponding limiting hole 2 410, rotating wheel 407 can be limited to prevent rotating wheel 407 from rotating due to external collision, causing displacement of the detector.

[0035] Specifically, the limiting assembly 8 includes a mounting groove 801 . The inner side of the socket 6 is provided with the mounting groove 801 . The upper and lower sides of the plug 7 are fixedly provided with mounting plates 802 . The mounting plates 802 are matched with the mounting groove 801 .

[0036] In this embodiment, when the plug 7 is placed into the socket 6, the mounting plate 802 will also slide into the mounting groove 801 of the socket 6, and then cooperate with other limiting components 8 to accurately limit the position of the mounting plate 802 to prevent it from accidental displacement or loosening during use.

[0037] Specifically, a spring 803 is installed inside the socket 6, and a movable plate 804 is fixedly connected to the side of the spring 803. A clamping rod 805 is fixedly installed on the side of the movable plate 804 away from the spring 803.

[0039] Specifically, the fixing rod 2 and the lifting rod 3 are both made of stainless steel.

[0040] In the present embodiment, the fixing rod 2 and the lifting rod 3 made of stainless steel are not easy to rust or deform, and the high strength can ensure the stability and reliability of the fixing rod 2 and the lifting rod 3 during use.

[0041] The working principle and use process of the utility model: by fixing the base 1 in a suitable position, the chemical waste gas detection device can be fixed on the ground. When the height of the detector body 5 needs to be adjusted, first press the pressing rods 807 on the upper and lower sides inward, then put the plug 7 into the socket 6, at this time the mounting plate 802 will slide into the mounting groove 801, and then release the pressing rod 807. Under the elastic force of the spring 803, the movable plate 804 and the clamping rod 805 move in the direction close to the mounting groove 801, so that the clamping rod 805 can be clamped in the clamping groove 806 of the mounting plate 802, and the plug 7 and the socket 6 are fixed together. Then, the rotating wheel 407 is rotated to drive the bevel gear 2 406 to rotate. Due to the precise meshing transmission relationship between the bevel gears, the bevel gear 1 405 rotates accordingly, thereby driving the threaded rod 401 to rotate. Under the interaction between the external thread of the threaded rod 401 and the internal thread of the lifting frame 402, the lifting frame 402 can move up and down smoothly, thereby driving the connecting rod 403 and the detector body 5 to make displacement adjustments in the up and down directions. Finally, the limit rod is clamped in the limit hole 1 409 and the corresponding limit hole 2 410, so that the rotating wheel 407 can be limited to prevent the rotating wheel 407 from rotating due to external collision, causing the detector to shift. This flexible adjustment of the height of the detector body 5 can make it closer to the concentration distribution area of ​​the target gas, effectively improve the accuracy and sensitivity of the detection, and ensure the efficiency and accuracy of the detection work. In addition, even if the detector shakes during the up and down movement, the plug 7 will not loosen, which can further ensure the accuracy of the detection results.
