Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

The utility model provides a gas pipe network leakage monitoring equipment based on diffusing pipe 3, this equipment includes diffusing pipe 3, gas collecting box 4 and blast pipe 5, one end of diffusing pipe 3 is buried in secret gas pipeline 1 top, the other end of diffusing pipe 3 stretches out stereoplasm ground 2 and passes through sealed flange joint with the air inlet of gas collecting box 4, the gas collecting box middle part is provided with the gas detection sensor 6 that is used for detecting whether the gas exists, be provided with the gas outlet on the lower part lateral wall of gas collecting box 4, blast pipe 5 with the gas outlet of gas collecting box 4 communicates, preferably, the height that diffusing pipe 3 stretched into in the gas collecting box 4 is greater than the height of gas collecting box 4 gas outlet, makes through diffusing pipe 3 the gas that gets into in the gas collecting box 4 earlier to the upper portion diffusion gathering of gas collecting box 4, only when the upper portion of gas collecting box 4 is whole to be piled up with the gas, the gas is discharged to the outside from the exhaust pipe 5; the outer side of the gas collection box 4 is also provided with a control terminal 8 connected with the gas detection sensor 6 through a conduit 7, and the control terminal 8 is used for receiving a gas detection result of the gas detection sensor 6.

Preferably, the gas detection sensor includes, but is not limited to, a semiconductor sensor, an infrared sensor, a catalytic combustion sensor, and a laser sensor.

Preferably, the control terminal 8 includes an LCD display screen, a single chip microcomputer, an indicating unit, a storage unit, a power supply module and a communication unit, the single chip microcomputer is respectively connected with the gas detection sensor 6 and the indicating unit, receives a gas detection result of the gas detection sensor 6 and controls the indicating unit to alarm according to the gas detection result, and specifically, when the gas detection result indicates that gas exists, the indicating unit is controlled to alarm; the LCD display screen is connected with the single chip microcomputer and used for displaying the gas detection result; the storage unit and the single chip microcomputer are used for storing the gas detection result; the communication unit is connected with the storage unit and used for uploading the gas detection result to a cloud background; the power supply module is used for supplying power to the LCD display screen, the single chip microcomputer, the indicating unit, the storage unit and the communication unit.

When the gas pipeline leakage detection device is used, the gas pipeline network leakage detection device is arranged above the gas pipeline 1 at intervals, wherein the diffusing pipe 3 is a hollow pipe and is made of plastic or metal; one end of the diffusing pipe 3 is embedded on the gas pipeline 1, and the other end of the diffusing pipe 3 is exposed on the hard ground and connected with the gas collecting box 4; when there is a leak in the gas pipe, since the gas has diffusibility and the ground other than the diffusing pipe 3 is the hard ground 2, the leaked gas can preferentially escape out of the ground through the diffusing pipe 3, and thus is detected by the gas detection sensor 6 disposed in the gas header 4.

In addition, when the leakage port of the gas pipeline 1 is small, the leakage amount of the gas in unit time is correspondingly small, so that the gas flowing out of the diffusing pipe 3 in unit time is not easy to be detected by the gas detection sensor 6 due to low concentration; in order to solve the problem, the gas needs to be enriched, and the technical scheme adopted by the application is that the diameter of the exhaust pipe 5 is smaller than that of the diffusing pipe 3, so that the air inflow of the gas collecting box 4 is larger than the air outflow, the gas flowing out of the diffusing pipe 3 is gathered in the gas collecting box 4, and the gas concentration in the gas collecting box 4 of the crusher is improved.
