[0024] See also Figure 1 , 2 , 3, 4, 5, and 6, the utility model provides a technical solution: a mobile monitoring device for underground gas pipelines, comprising: a supporting bottom box 1 with rollers at the bottom; an angle limiting component rotatably disposed at one end of the supporting bottom box 1, the angle limiting component comprising a connecting rod 8 rotatably disposed at the end of the supporting bottom box 1 through a rotating shaft, a positioning screw 9 is threadedly connected to the middle part of the connecting rod 8, and a supporting tube 4 is vertically welded to the connecting rod 8; a detection box 3 is fixedly connected to the outside of the supporting tube 4 through a clamp, an air storage box 12 is fixedly connected to the inside of the detection box 3, a control unit and an alarm system are arranged inside the detection box 3, and the alarm system is a sound alarm and a flashing light The lamp and the air storage box 12 are provided with an odor sensor 13 inside, and the odor sensor 13 is a methane sensor or a natural gas sensor; the extension rod 5 is slidably placed inside the support tube 4, and a fixing mechanism is installed at the end of the support tube 4, and the fixing mechanism includes a threaded tube 15 threadedly connected to the end of the support tube 4 and a fixed pressing plate 16 matched therewith, and the fixed pressing plate 16 is a plastic sheet with an inclined structure, and the fixed pressing plate 16 is evenly distributed at the end of the support tube 4 with the center of the circle of the support tube 4 as the center, and the threaded tube 15 is rotated so that the threaded tube 15 squeezes the fixed pressing plate 16, so that the extension rod 5 is squeezed and fixed by the fixed pressing plate 16.

[0025] It should be noted that when the device is used in the present invention, the extension rod 5 is pulled out from the inside of the support tube 4, and then the threaded tube 15 is rotated to a direction close to the fixed pressing plate 16, and the outer side of the fixed pressing plate 16 is squeezed by the inner wall of the threaded tube 15. Under the structure of its inclined surface, the fixed pressing plate 16 squeezes and fixes the extension rod 5, and the detection box 3 is rotated to a suitable angle, and then the positioning screw 9 is rotated to be inserted into the positioning hole 10 of the corresponding angle, so as to fix the angle between the support bottom box 1 and the detection box 3, and the entire device is pushed forward by the extension rod 5. During this period, the air pump 11 inside the support bottom box 1 draws the bottom air into the air storage box 12, and the odor sensor 13 is in contact with the air. The gas storage box 12 is inspected inside and an alarm is sounded when a leak is detected. The angle limiting component allows the user to adjust the angle between the supporting base box and the detection box to adapt to the layout and structure of different underground pipelines. The flexibility ensures the effectiveness of the monitoring device in various environments. The detection box 3 can be folded by adjusting the angle to conveniently reduce the overall volume of the device, making it convenient to move and carry. The device is equipped with an odor sensor that can quickly and accurately detect gas leaks, thereby sounding an alarm in time to prevent possible dangerous incidents. The extension rod is fixed to the inside of the support tube by a fixing mechanism, and the angle between the fixing base box and the detection box is fixed to ensure the stability and accuracy of the device during movement.

[0026] See also Figure 1 , 2 As shown in Figures 4 and 5, the moving part includes two moving wheels 2 rotatably mounted on one end of the supporting bottom box 1, and the other end of the supporting bottom box 1 is rotatably connected to a self-locking wheel.

[0027] It should be noted that, in the present invention, the moving wheel 2 moves above the ground when pushed, and the device can be moved on the ground to cover a wider area, so as to effectively monitor the status of the gas pipeline. The mobility can help to find the location of the pipeline leakage in time.

[0028] See also Figure 4 , 6 As shown, a battery 14 is fixedly connected to the interior of the supporting bottom box 1, an air pump 11 is fixedly connected to the interior of the supporting bottom box 1, an output end of the air pump 11 is connected to the air storage box 12 through a pipeline, and an input end of the air pump 11 extends to the bottom of the supporting bottom box 1 through a pipeline.

[0029] It should be noted that the battery of the utility model is a rechargeable battery, which provides necessary power support to ensure the normal operation of the air pump and the sensor. During detection, the air pump 11 draws ground air into the air storage box 12, and the air is temporarily stored in the storage box. The odor sensor analyzes the components in the stored air to detect whether there is a gas leak or other harmful gas. The air pump enables the equipment to actively draw air from the ground into the air storage box. The active sampling method is more effective and controllable than relying on natural air flow.

[0030] See also Figure 1 , 2 As shown in Figure 5, a rotation groove 7 is provided at one end of the supporting bottom box 1, and a connecting rod 8 is rotatably connected to the rotation groove 7. The bottom of the rotation groove 7 is an arc structure, and a plurality of positioning holes 10 cooperating with the positioning screw 9 are equidistantly provided on the outer side of the arc structure.

[0031] It should be noted that the connecting rod 8 of the utility model is placed in the rotating groove 7 by rotating the rotating shaft. The inner wall of the rotating groove 7 is equidistantly provided with a plurality of positioning holes 10 with the center of the rotating shaft as the axis. When fixing the angle of the connecting rod 8, the connecting rod 8 is rotated to a specified angle, and then the positioning screw 9 is screwed so that the positioning screw 9 is inserted into the corresponding positioning hole 10, so as to fix the angle of the connecting rod 8, thereby determining the angle between the support tube 4 and the extension rod 5, which is convenient for adjustment according to body height or folding and storage.

[0032] See also Figure 1 , 2 As shown, a control switch box 6 is installed at the end of the extension rod 5.

[0033] It should be noted that an operation panel and a display screen are installed on the outside of the control switch box 6 of the utility model. The operation panel includes an air pump start and stop button and a reset button. By controlling the start and stop of the air pump, the frequency of air sampling can be manually adjusted or sampling can be stopped as needed. The reset button is used to restart the system or clear the alarm status. The display screen is used to display the status of the monitoring system, the readings of the odor sensor or other relevant information.

[0034] See also Figure 1 , 2 As shown in FIG. 3 , the fixed pressing plates 16 are fixedly connected to the end of the support tube 4 at equal distances, and the thickness of the fixed pressing plates 16 gradually increases in the direction away from the threaded tube 15 .

[0035] It should be noted that the fixed pressing piece 16 of the utility model is designed to gradually increase in thickness in the direction away from the threaded tube 15, so that an inclined surface is formed on the outside of the control switch box 6. The inclined surface design allows the pressing piece to generate a centripetal force when squeezed by the inner wall of the threaded tube, thereby fixing or releasing the extension rod 5, so that the length of the extension rod 5 can be flexibly adjusted, and the telescopic length of the extension rod can be adjusted as needed to adapt to different usage scenarios or needs.
