Problems solved by technology

This kind of leak detection method has a large workload, and it is inconvenient to monitor in remote places. Once it is missed, there will be a very big safety hazard. Therefore, an anti-leakage gas pipeline that can automatically monitor whether the gas is leaking is needed.

Embodiment 1

[0024] Such as figure 1 , 2 The anti-leakage gas pipeline shown in . An inner shell 10 is arranged inside, and an outer shell 9 is arranged on the outside of the inner shell 10, and the outer shell 9 is installed on the casing 2, and a fixing seat 12 is installed on the bottom of the outer shell 9, and a motor 13 is arranged inside the fixing seat 12 , the inside of the inner shell 10 is provided with a sleeve 11, the bottom of the sleeve 11 is fixedly connected with the output end of the motor 13, the inside of the sleeve 11 is provided with a first through hole 15, and the outside of the sleeve 11 is provided with a fixed connected gasket 14, the inner shell is also provided with a second through hole 16, and the top of the outer shell 9 is provided with a storage battery pack 17, a controller 18 and a wireless communication device 19, and the storage battery pack 17 communicates with the solar cell through a wire 8 The panels 3 are electrically connected, the solar panel ...

Embodiment 2

[0030] As shown in the figure, the difference between this embodiment and Embodiment 1 is that the number of gas concentration sensors 4 is set to two, and the two gas concentration sensors 4 are installed on the top and bottom of the pipeline body 1 respectively. The soil is covered, and the gas leaking from the bottom may not be detected at the bottom. By setting the gas concentration sensor 4 at the bottom, it is convenient to monitor whether there is gas leakage at the bottom of the pipeline body 1, so that the monitoring is more accurate.

[0031] The working principle is as follows: the converted energy is stored in the underground battery pack 17 through the wire 8 through the solar panel 3 on the ground surface, and is controlled by the controller 18 to provide electric energy for the gas concentration sensor 4, the motor 13 and the wireless communication device 19. The gas concentration sensor 4 checks whether the gas is leaking. When the gas concentration exceeds the ...

Abstract

The invention relates to an anti-leakage gas pipeline, and belongs to the technical field of pipelines. The anti-leakage gas pipeline comprises a pipeline body, a bushing and a gas concentration sensor are mounted on the pipeline body, the bushing is provided with an inner shell and an outer shell, a motor is arranged in a fixed seat, the inner shell is provided with a sleeve, a first through hole, a sealing pad and a second through hole, the outer shell is provided with a motor, a storage battery, a controller and a wireless communication device, and the storage battery is electrically connected with a solar panel through a lead. The pipeline body has good toughness, corrosion resistance, oxidation resistance, moisture resistance, compression resistance and vibration reduction performance, gas does not easily leak, the solar panel supplies power for other components, leakage places are conveniently and timely monitored and accurately positioned by the gas concentration sensor with a GPS (global positioning system), rush repair is facilitated, the controller isolates gas in the bushing by the motor when leakage happens, and gas leakage is decreased.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to an anti-leakage gas pipeline. Background technique [0002] Natural gas pipeline refers to the pipeline that transports natural gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission pipelines. Natural gas pipelines are generally buried in the ground, and they are prone to corrosion and leakage if they exist under the soil for a long time. Therefore, the welding joints must be repaired frequently, and sometimes natural gas leaks from the joints due to untimely maintenance. Once the pipeline leaks, due to the flammable and combustible Explosive, so there is a very big security risk. [0003] The existing monitoring method is mainly the active leak detection method of the gas pipeline network, which is the comprehensive use of leak detection plan + full-time leak detection team + various instrum...
