It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The present invention provides a municipal manhole cover with the function of detecting harmful gases in pipelines, comprising: a manhole cover body 1, a detector 2, an adjustment structure 3, and an auxiliary structure 4. The detector 2 is installed on one side of the manhole cover body 1 by means of the adjustment structure 3, the adjustment structure 3 is provided on one side of the manhole cover body 1, and the auxiliary structure 4 is provided on one side of the manhole cover body 1.

[0032] In the embodiments of this utility model, please refer to Figure 2The adjustment structure 3 includes four positioning plates 305, which are fixedly connected to the manhole cover body 1. Two connecting plates 301 are fixedly connected to both sides of the detector 2. A fixing rod 302 is slidably connected to the inner wall of each connecting plate 301. An adjustment plate 303 is fixedly connected to one end of each fixing rod 302. A spring 304 is sleeved on the arc surface of the fixing rod 302. Both ends of the spring 304 are fixedly connected to the adjustment plate 303 and the connecting plate 301, respectively. An auxiliary plate 306 is fixedly connected to the side of the adjustment plate 303. The manhole cover body 1 is an iron cover. By setting the adjustment structure 3, the detector 2 can be easily installed or disassembled, facilitating inspection and maintenance by personnel. This improves work efficiency and reduces maintenance time and labor costs. The auxiliary plate 306 has openings on both sides... The auxiliary plate 306 has anti-slip texture 307, which is evenly distributed on both sides. The anti-slip texture 307 can increase the friction of the auxiliary plate 306 and prevent the personnel from slipping when moving the auxiliary plate 306. Two magnets 310 are fixedly connected to both sides of the detector 2. The magnets 310 are attracted to the manhole cover body 1. The magnets 310 can fix the detector 2 more firmly and prevent the detector 2 from shaking easily. Two round blocks 309 are fixedly connected to one side of the manhole cover body 1. The inner wall of the two round blocks 309 is slidably connected to the limit rod 308. The limit rod 308 is fixedly connected to the detector 2. The round blocks 309 and the limit rod 308 can position the detector 2, making the position of the detector 2 more accurate during the installation and fixing process.

[0033] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The auxiliary structure 4 includes a sealing ring 41, which abuts against the manhole cover body 1. Several connecting blocks 42 are fixedly connected to the inner wall of the sealing ring 41. A screw 43 is fixedly connected to one side of each connecting block 42. Several fixing seats 45 are fixedly connected to one side of the manhole cover body 1. A connecting disc 44 is threaded onto the arc surface of the screw 43, and the connecting disc 44 abuts against the fixing seats 45. By setting the auxiliary structure 4, the sealing performance of the manhole cover body 1 can be increased, preventing gaps from forming during use and preventing harmful gases from leaking out of the pipe. To ensure safety during use, a soft pad 46 is fixedly connected to one side of the connecting plate 44. The soft pad 46 is a rubber pad, which can prevent the connecting plate 44 from directly contacting the fixed seat 45, thus preventing the fixed seat 45 from being worn. Several auxiliary rods 47 are fixedly connected to the inner wall of the sealing ring 41. The arc surfaces of the auxiliary rods 47 are slidably connected to positioning blocks 48. The positioning blocks 48 are fixedly connected to the manhole cover body 1. The auxiliary rods 47 and the positioning blocks 48 can make the sealing ring 41 more stable and achieve a more secure fixation.

[0034] The working principle of the municipal manhole cover with the function of detecting harmful gases in pipelines provided by this utility model is as follows: By setting the adjustment structure 3, the auxiliary plate 306 is first pressed with the help of the anti-slip texture 307, so that the auxiliary plate 306 drives the adjustment plate 303 to move. The adjustment plate 303 drives the fixed rod 302 to move inside the connecting plate 301. At the same time as the adjustment plate 303 moves, it also drives the spring 304 to retract. At this time, the detector 2 is placed on one side of the manhole cover body 1. Then the auxiliary plate 306 is released. When the auxiliary plate 306 is released, the spring 304 will... The adjusting plate 303 is moved, which in turn moves the fixing rod 302 until the fixing rod 302 is inserted into the positioning plate 305. The anti-slip texture 307 can increase the friction of the auxiliary plate 306 and prevent the personnel from slipping when moving the auxiliary plate 306. The magnet 310 can fix the detector 2 more firmly and prevent the detector 2 from shaking easily. The round block 309 and the limiting rod 308 can position the detector 2, making the position of the detector 2 more accurate during the installation and fixing process.

[0035] By setting the auxiliary structure 4, the sealing ring 41 is first moved and placed on one side of the manhole cover body 1. While the sealing ring 41 is moving, the screw 43 on one side of the connecting block 42 will be placed inside the fixed seat 45. Then, the connecting plate 44 on the screw 43 is rotated to fix the connecting plate 44 to the fixed seat 45. At this time, the sealing ring 41 is fixed. The soft pad 46 can prevent the connecting plate 44 from directly contacting the fixed seat 45, thus preventing the fixed seat 45 from being worn. The auxiliary rod 47 and the positioning block 48 can make the sealing ring 41 more stable and achieve a more secure fixation.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
