[0002] City gas pipe network is an important part of modern city infrastructure, with the acceleration of urbanization, the scale of gas pipe network expands unceasingly. In order to guarantee the normal operation of pipe network and public safety, regular inspection work is particularly important. The traditional gas pipe network inspection method mainly relies on artificial inspection and artificial inspection instrument, but this way has many shortcomings.

[0003] Firstly, artificial inspection efficiency is low, and is susceptible to human factors. Inspection personnel need to enter the various areas of pipe network regularly to check, and there are inevitably omissions and oversights in the working process, especially in some complex, dangerous environment, artificial inspection is difficult to ensure comprehensiveness and efficiency. In addition, artificial inspection often cannot find dangerous conditions such as gas leakage in the first time, and it is difficult to take emergency measures in time, which increases the risk of accidents. Secondly, the traditional inspection equipment is mostly single-function gas detection instrument, usually needs manual operation, and cannot effectively cooperate with inspection vehicles and detection equipment, resulting in lack of systematicness and automation of inspection work, and unable to record the inspection process and detection data in real time. Once gas leakage and other emergency situations occur, the reaction speed of the traditional inspection equipment is slow, which is difficult to meet the demand of rapid response and timely processing. In addition, the current gas leakage monitoring equipment is mostly dependent on static installation in fixed position for monitoring, lacks flexibility and adaptability. The layout of most equipment needs to estimate the potential area of gas leakage in advance, and it is difficult to achieve global monitoring. In the monitoring range, the distribution of equipment may not cover all potential risk points, and there is a certain blind area. UTILITY MODEL CONTENTS

[0043] Box door 11, box door 11 is installed on the left side of box body 2 through opening and closing assembly 12.

[0044] In this embodiment, the AGV 1 is an industrial vehicle powered by a battery, which can automatically move according to a preset route, realize automatic inspection of the monitoring device, and realize automatic inspection of the monitoring device. The air in the detection area is drawn into the detection chamber 4 by the air fan 6, and the methane concentration in the current air is monitored by the methane sensor 7. In the normal state, the sealing assembly 8 seals the second grid hole 15, and the first grid hole 14 is connected with the outside. At this time, the air passes through the detection chamber 4 and is discharged to the external environment. When the methane sensor 7 detects that the methane concentration in the air exceeds the preset value, the sealing assembly 8 opens the second grid hole 15 and closes the first grid hole 14, and at the same time increases the power of the air fan 6, so that the air fan 6 draws the external mixed methane into the air bag 9 for storage, thereby avoiding accidents caused by excessive local methane concentration.

[0045] Embodiment 2

[0046] As shown in Figures 3-5 based on the same idea as in the above embodiment 1, the present embodiment also proposes:

[0047] The sealing assembly 8 comprises a first sealing plate 81 and two symmetrically arranged second sealing plates 82. The first sealing plate 81 is attached to the side wall of the partition 3.

[0048] The second sealing plate 82 is attached to the inner wall of the detection chamber 4. The second sealing plate 82 and the side wall of the first sealing plate 81 are both fixed with a rack 83.

[0049] The corresponding two racks 83 are engaged with the same gear 86.

[0050] The gear 86 is rotatably installed on the inner wall of the detection chamber 4.

[0051] The first electric push rod 85 is fixed between the top wall of the first sealing plate 81 and the top wall of the detection chamber 4.

[0052] A fourth grid hole 87 is formed in the first sealing plate 81 and matched with the second grid hole 15. A third grid hole 84 is formed in the second sealing plate 82 and matched with the first grid hole 14.

[0053] The L-shaped guide plates 16 are symmetrically fixed on the inner wall of the detection chamber 4. The second sealing plate 82 is slidably installed between the corresponding two L-shaped guide plates 16. The vertical plates 17 are symmetrically fixed on the inner wall of the detection chamber 4. The first sealing plate 81 is slidably installed between the two vertical plates 17.

[0054] The opening and closing assembly 12 comprises a mounting plate 121 fixed on the side wall of the box body 2. The second electric push rod 122 is rotatably installed on one side of the mounting plate 121.

[0059] In the embodiment, the controller is arranged to intelligently control the work of the whole device. Under normal conditions, the AGV trolley 1 performs inspection along the preset path, the air suction fan 6 is in a low-power working state, the air suction fan 6 sucks the air in the detection area into the detection chamber 4, and the methane concentration in the current air is monitored through the arranged methane sensor 7. When the methane sensor 7 detects that the methane concentration in the air exceeds the preset value, the controller controls the air suction fan 6 to operate at high power, and controls the first electric push rod 85 to work, so that the first electric push rod 85 drives the movement of the first sealing plate 81, so that the fourth grid hole 87 on the first sealing plate 81 corresponds to the second grid hole 15. In the movement process of the first sealing plate 81, the gear 86 and the rack 83 are arranged to drive the movement of the second sealing plate 82 on both sides, the third grid hole 84 on the second sealing plate 82 is dislocated from the first grid hole 14, so that the second sealing plate 82 blocks the first grid hole 14. At this time, the air mixed with methane sucked into the detection chamber 4 will be conducted into the air bag 9 for collection. The opening and closing assembly 12 is arranged to control the opening of the box door 11. When the air mixed with methane is inflated into the air bag 9, the air bag 9 can extend outward, so that the air bag 9 can store more air mixed with methane. At the same time, the controller controls the alarm 13 to work, prompting the worker to repair the specified area.

[0060] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
