DETAILED DESCRIPTION

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments: Example 1

[0027] like Figure 1-5 As shown, the utility model provides a gas pipe network leakage detection and analysis device, including a detection device 1, a gas detection sensor 5 and an infrared ranging sensor 10. The detection device 1 includes a first annular sleeve 2, a center annular sleeve 3 and a second annular sleeve 4 which are overlapped and arranged in sequence.

[0028] The outer walls of the first annular sleeve 2, the central annular sleeve 3, and the second annular sleeve 4 are all provided with a through-opening groove 9, and the first annular sleeve 2, the central annular sleeve 3, and the second annular sleeve 4 are staggered along the central axis. The staggered distribution state formed by the through-opening grooves 9 provided on the first annular sleeve 2, the central annular sleeve 3, and the second annular sleeve 4 enables the detection device 1 to form a relatively closed loop state on the outer wall of the pipeline, ensuring that the structure can operate stably without the problem of random deflection and falling off.

[0029] Built-in annular grooves 8 are provided on opposite sides of the first annular sleeve 2 and the second annular sleeve 4, a dual-axis drive motor 6 is fixedly connected to the inner wall of the central annular sleeve 3, motor gear rods 16 are fixedly connected to both ends of the dual-axis drive motor 6, teeth for matching the motor gear rod 16 are fixedly distributed on the inner wall of the built-in annular groove 8, and auxiliary docking gear rods 7 for matching the built-in annular grooves 8 are distributed in annular arrays on both sides of the central annular sleeve 3.

[0030] One end of the auxiliary docking gear rod 7 is rotatably connected to one side of the central annular sleeve 3, and one end of the motor gear rod 16 away from the dual-axis drive motor 6 is fixedly connected to a limiting circular plate, which overlaps one side of the tooth, and the infrared ranging sensor 10 is located on one side of the second annular sleeve 4. Example 2

[0031] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the inner wall of the first annular sleeve 2 is fixedly connected with a first oblique telescopic column 11, the inner wall of the center annular sleeve 3 is fixedly connected with a center telescopic column 12, and the inner wall of the second annular sleeve 4 is fixedly connected with a second oblique telescopic column 13.

[0032] The top ends of the first oblique telescopic column 11 and the second oblique telescopic column 13 are both rotatably connected to ball wheels 17 , and the top end of the central telescopic column 12 is rotatably connected to anti-skid wheels.

[0033] The distribution directions of the first oblique telescopic columns 11 and the second oblique telescopic columns 13 are both offset relative to the central telescopic column 12 .

[0034] A storage battery 14 is fixedly connected to the inner wall of the central annular sleeve 3 , and one side of the storage battery 14 is electrically connected to a microcontroller 15 .

[0035] The first annular sleeve 2, the center annular sleeve 3, and the second annular sleeve 4 are all composed of two groups of semi-arc plates fixedly connected by a clamping member. When the motor gear rod 16 drives the first annular sleeve 2 and the second annular sleeve 4 to rotate, the limiting circular plate overlaps one end of the tooth, and the first annular sleeve 2 and the second annular sleeve 4 are limited to both sides of the center annular sleeve 3. When disassembly is required, the first annular sleeve 2 and the second annular sleeve 4 are disassembled, and the remaining part is rotated so that the limiting circular plate is dislocated from the tooth.

[0036] The following is a detailed description of the working principle of the gas pipeline leak detection and analysis equipment.

[0037] like Figure 1-5 As shown, when in use, when the detection device 1 moves on the outer wall of the gas pipe, the infrared distance sensor 10 installed on the second annular sleeve 4 detects that there is a pipeline obstruction in front. At this time, after the microcontroller 15 receives the signal transmitted by the infrared distance sensor 10, it adjusts the dual-axis drive motor 6 to start, and the dual-axis drive motor 6 drives the motor gear rod 16 to rotate. When the motor gear rod 16 rotates, the teeth on the inner wall of the built-in annular groove 8 drive the first annular sleeve 2 and the second annular sleeve 4 to deflect in the same direction. When the second annular sleeve 4 rotates to the point where the card opening groove 9 on it is flush with the card opening groove 9 on the center annular sleeve 3, Then the dual-axis drive motor 6 stops rotating, and the detection device 1 moves forward as a whole until the second annular sleeve 4 moves to the other side of the pipe clamp and stops. After that, the dual-axis drive motor 6 is started again, so that the motor gear rod 16 drives the first annular sleeve 2 and the second annular sleeve 4 to rotate again. When the through-card opening groove 9 on the first annular sleeve 2 and the through-card opening groove 9 on the center annular sleeve 3 are flush with each other, the through-card opening groove 9 on the second annular sleeve 4 is deflected to the lower side of the pipeline. Then, the detection device 1 is pulled forward as a whole again, and the first annular sleeve 2 can be free from the obstruction of the pipe clamp, so that the detection device 1 as a whole can continue to move forward for detection work.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
