An adjusting box 2 is located on the left side of the inner cavity of the sewage manhole 1. Threaded rods 3 are movably connected to the top and bottom of the inner cavity of the adjusting box 2 via bearings. A threaded sleeve 4 is threadedly connected to the surface of the threaded rod 3. A connecting block 5 is fixedly connected to the right side of the threaded sleeve 4. An adjusting plate 6 is fixedly connected to the right side of the connecting block 5. A clamping assembly 7 is located at the bottom of the adjusting plate 6. The clamping assembly 7 includes a first L-shaped plate 701 fixedly installed on the left side of the bottom of the adjusting plate 6. A movable groove 702 is opened on the right side of the inner cavity of the adjusting plate 6. A second L-shaped plate 703 is slidably connected to the top of the inner cavity of the movable groove 702. A movable rod 704 is fixedly connected to the right side of the second L-shaped plate 703. A spring 705 is sleeved on the surface of the movable rod 704. The detection device body 10 is located between the first L-shaped plate 701 and the second L-shaped plate 703. A handle is fixedly connected to the right side of the 4. The inner cavity of the clamping assembly 7 clamps and connects the detection device body 10. A support rod 8 is fixedly connected to the left side of the bottom of the adjusting plate 6. An air inlet assembly 9 is fixedly connected to the bottom of the support rod 8. The air inlet assembly 9 includes an air inlet plate 901 fixedly installed at the bottom of the support rod 8. A fan 902 is installed in the inner cavity of the air inlet plate 901. By setting the adjusting box 2, threaded rod 3, threaded sleeve 4 and connecting block 5, the adjusting plate 6 can be driven to adjust the depth in the sewage pit 1, thereby enabling gas detection at different depths in the sewage pit 1 and improving the detection effect. The clamping assembly 7 facilitates the clamping and installation of the detection device body 10, making it easier for users to disassemble and maintain the detection device body 10 later. The air inlet assembly 9 blows the air in the sewage pit 1 toward the detection device body 10, further improving the gas detection effect.

[0025] Example 2: Reference Figure 1 , Figure 2 and Figure 3 A slide rail 11 is fixedly connected to the left side of the inner cavity of the regulating box 2. A slider 12 is slidably connected to the surface of the slide rail 11. The right side of the slider 12 is fixedly connected to the threaded sleeve 4, which can limit and guide the movement of the threaded sleeve 4, increasing the stability when the threaded rod 3 drives the threaded sleeve 4 to move up and down. A slide groove 13 is opened at the top of the inner cavity of the movable groove 702. A slide seat 14 is slidably connected to the inner cavity of the slide groove 13. The bottom of the slide seat 14 is fixedly connected to the second L-shaped plate 703, which can limit and guide the movement of the second L-shaped plate 703, increasing the stability when clamping and fixing. The top of the threaded rod 3 passes through the regulating box 2 through a bearing and is fixedly connected to a handle 15, which makes it easy for the user to rotate the threaded rod 3. Mounting plates 16 are fixedly connected to the top and bottom of both sides of the regulating box 2. The mounting plates 16 are bolted to the inner wall of the sewage pit 1, which makes it easy to install and fix the regulating box 2.

[0026] The working principle is as follows: In use, rotating the handle 15 drives the threaded rod 3 to rotate, which in turn drives the threaded sleeve 4 to move up and down. The up and down movement of the threaded sleeve 4 can drive the adjusting plate 6 to adjust the depth in the sewage pit 1 through the connecting block 5. This allows the detection equipment body 10 to perform gas detection at different depths in the sewage pit 1, improving the detection effect. At the same time, during the detection process, starting the fan 902 can blow the air in the sewage pit 1 toward the detection equipment body 10, which can further improve the gas detection effect. When maintenance of the testing equipment body 10 is required, the testing equipment body 10 is moved to the sewage pit 1 by rotating the handle 15, and then the pull handle is pulled to move the movable rod 704 to the right. The movable rod 704 moves the second L-shaped plate 703 to the right. At this time, it is convenient for the user to disassemble and maintain the testing equipment body 10, thereby improving the maintenance effect.

[0027] In summary, this flammable and explosive gas monitoring device, capable of monitoring different depths in a sewage manhole, utilizes an adjusting box 2, a threaded rod 3, a threaded sleeve 4, and a connecting block 5 to drive an adjusting plate 6 within the sewage manhole 1 for depth adjustment. This allows for gas detection at different depths within the sewage manhole 1, improving the detection effect. The clamping component 7 facilitates the clamping and installation of the detection device body 10, enabling users to easily disassemble and maintain the device body 10 later. The air inlet component 9 directs air from the sewage manhole 1 towards the detection device body 10, further enhancing the gas detection effect.
