Embodiment 1

[0029]Embodiment 1: When the device is in use, if the gas pipe 5 leaks, the leaked gas will first be discharged between the outer protective pipe 1 and the inner protective pipe 3 through the vent hole 4, and the combustible gas sensor 26 close to the leaked gas will first It detects that the combustible gas content in the air exceeds the standard, and transmits the super standard signal to the control computer 21 through the data line 22, and then the control computer 21 judges the approximate location of the gas leakage according to the combustible gas sensor 26 that sends the signal, and then controls it through the control computer 21. The alarm horn 25 near the leak plays the alarm sound to remind the surrounding residents that the gas leakage occurs, so that it takes certain protective measures, and then the control computer 21 controls the ventilation fan 13 to start, and a part of the ventilation fan 13 sucks the outside air into the The inside of the outer protective t...

Embodiment 2

[0030] Embodiment 2: When more accumulated water is generated inside the outer protective tube 1, first the water level of the accumulated water rises and the buffer spring 18 is squeezed by the floating plate 19, and the floating plate 19 that floats up simultaneously squeezes the travel switch 20, so that The travel switch 20 is triggered, and the drainage pump 16 is started, so that the accumulated water inside the outer protection pipe 1 is pumped into the interior of the drainage pipe 17 through the drainage pump 16 through the water delivery pipe 15, and discharged from the surface 6 through the drainage pipe 17, thereby achieving automatic Control to avoid water accumulation inside the outer protective tube 1 .

Embodiment 3

[0031] Embodiment 3: When the control computer 21 shows that there is a failure of the combustible gas sensor 26, by entering the inside of the maintenance tank 7 at the corresponding position, first disconnect the transmission plug 10 from the transmission socket 24, and then turn and adjust the hand dial 11 to make the installation The rod 9 rotates, so that the mounting rod 9 is separated from the threaded seat 8, and the combustible gas sensor 26 is taken out along with the mounting rod 9, so that the combustible gas sensor 26 can be easily repaired or replaced.

Abstract

The invention discloses an anti-leakage structure of a gas pipe, and relates to the technical field of gas pipeline leakage prevention. The following scheme aiming at the problems that when an existing gas pipeline is not provided with an active anti-leakage device, leaked gas is not easy to exhaust out of the atmosphere in time when the gas pipeline leaks, and certain potential safety hazards exist is provided. The device comprises an outer protection pipe, a transmission socket, a control computer, a water conveying pipe, ground surface and an inner protection pipe, the inner protection pipeis located in the outer protection pipe, uniformly distributed supporting rods are fixedly connected between the outer surface of the inner protection pipe and the inner wall of the outer protectionpipe, uniformly distributed threaded seats are fixedly connected to the surface of the outer protection pipe, and the threaded seats are located on the side, close to the ground surface, of the outerprotection pipe. According to the anti-leakage structure, combustible gas can be actively diluted and discharged; nearby residents can be quickly informed of leakage information; and meanwhile, latermaintenance is facilitated, the function of protecting the gas pipe is achieved, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of anti-leakage of gas pipelines, in particular to an anti-leakage structure of gas pipe fittings. Background technique [0002] Gas pipelines are important vehicles for transporting flammable gases such as natural gas. Explosion accidents caused by leakage of gas pipelines are not rare; gas pipelines have brought hidden dangers to people's life safety to a certain extent, so the use of gas pipelines is safe. deserve extra attention. [0003] The current gas pipelines usually transport gas by buying underground, and there is a lack of certain active leakage prevention devices. When the gas pipeline leaks, if the gas is not discharged smoothly, it is easy to cause the gas to accumulate, thereby bringing about the hidden danger of explosion. , and the current gas pipeline leak alarm device, when the gas leaks, the relevant management department and the residents around the leak cannot be notified in time, and...
