[0023] See also Figures 1 to 5The utility model provides a technical solution: a municipal pipeline polluted gas ventilation detection device, comprising: a casing 1, a controller 5 is fixedly installed in the middle of the casing 1, and a plurality of uniformly distributed gas detection sensors 2 are installed on the outer periphery of the casing 1. By setting the gas detection sensor 2, the gas detection sensor 2 here can be one or more of an infrared gas detection sensor 2, a hydrogen sulfide sensor, a carbon monoxide sensor, etc., the harmful polluted gas in the municipal pipeline can be detected, and then the gas detection sensor 2 can transmit the detection signal to the controller 5, and the controller 5 can notify the detection personnel of the signal through the external Internet of Things. Both sides of the outer periphery of the casing 1 are installed with a moving component 3, and a limited position mechanism 6 is arranged in the moving component 3; by setting the moving component 3, it is convenient for the moving component 3 to drive the device to move in the municipal pipeline, a marking component 4, and the marking component 4 includes a fixing frame 42, the fixing frame 42 is respectively arranged in the middle of both sides of the casing 1, and a plurality of uniformly distributed connecting frames 41 are fixedly installed on the surface of the fixing frame 42, and the connecting frame 41 is fixedly installed on the inner wall surface of the casing 1 on the same side at one end away from the fixing frame 42, and the middle of the fixing frame 42 is A plurality of evenly distributed limit seats 45 are fixedly installed, and a moving plate 43 is slidably installed in the limit seats 45. A marking pen 44 is installed in the middle of the moving plate 43 near the casing 1, and the marking arm passes through the casing 1. A fixed plate 47 is fixedly installed on one side of the moving plate 43 near the middle of the casing 1. Since the gas detection sensor 2 is arranged near the marking component 4, when the device is detected at a certain point in the municipal pipeline, the controller 5 will drive the stepper motor 46 according to the signal fed back by the gas detection sensor 2, thereby causing the cam 49 at the driving end of the stepper motor 46 to rotate. With the cooperation of the connecting plate 48 and the fixed plate 47, the movable plate 43 can slide in the limit seat 45. Since the fixed plate 47 is provided with a slide groove, when the cam 49 rotates, the connecting plate 48 can slide on the surface of the fixed plate 47, so that the movable plate 43 can move upward or downward without causing interference, thereby allowing the marking pen 44 to extend out of the casing 1. Moreover, since the marking pen 44 has different colors, the staff can observe the color level of the marking pen 44 after it is extended, and then judge the concentration of harmful pollutant gases in the municipal pipeline, thereby alerting the maintenance personnel.

[0024] A plurality of evenly distributed stepper motors 46 are fixedly installed in the middle of the fixed frame 42, and a cam 49 is fixedly installed at the driving end of the stepper motor 46. A connecting plate 48 is rotatably installed on the surface of the cam 49, and the connecting plate 48 is slidably installed on the surface of the fixed plate 47 on the same side. The moving component 3 includes a plurality of fixed seats 31, each of which is fixedly installed on the outer periphery of both sides of the casing 1 and arranged in a circle. A constraint groove 34 is provided in the middle of the fixed seat 31, and a moving seat 32 is slidably installed in the constraint groove 34.

The controller 5 is electrically connected to the gas detection sensor 2 and the stepper motor 46 respectively. By pulling the limit pin 62, the limit pin 62 will disengage from the limit hole 64, and then the moving seat 32 can move along the constraint groove 34 in the fixed seat 31, thereby adjusting the distance of the moving wheels 33. At this time, the staff can adjust the distance between the moving wheels 33 according to the inner diameter of the municipal pipeline. After the adjustment is completed, the limit pin 62 will be re-engaged in the limit hole 64 with the cooperation of the spring 63, thereby realizing the limit fixation of the moving seat 32, which is beneficial to ensuring the stability of the moving seat 32, and the moving wheel 33 is provided with a driving member, which can drive the moving wheel 33, thereby ensuring the smoothness of the movement of the device in the municipal pipeline.

Then, the device can be moved in the municipal pipeline. When the device moves into the municipal pipeline, the gas detection sensor 2 will detect the air in the pipeline. When harmful polluted gases appear, the controller 5 will control the stepper motor 46 to drive the corresponding cam 49 to rotate. In conjunction with the connecting plate 48 and the fixed plate 47, the moving plate 43 can be moved in the limit seat 45, and the color marking pen 44 that can reflect the concentration of harmful gases can be extended from the casing 1, thereby alerting the maintenance personnel.
