Whether the mode that detects the beam pipe and whether take place gas leakage still the manual work observes the beam pipe and whether has the damage now, this kind of mode efficiency is very low to consume a large amount of manpowers, and the environment under the mine is comparatively complicated, and local illumination is not enough a bit, can't effectual detection when detecting, the leak hunting mode effect of manual observation is very poor.

SUMMERY OF THE UTILITY MODEL

The invention provides a sulfur hexafluoride bundle tube leakage detection device for solving the problems.

The sulfur hexafluoride is a stable gas which is colorless, odorless, nontoxic and noncombustible, does not exist in natural air basically, detects whether the bundle tube leaks air or not by utilizing the property of the sulfur hexafluoride, and detects the specific position of the leakage of the bundle tube.

In order to achieve the purpose, the following technical scheme is adopted in the disclosure:

a sulfur hexafluoride bundle pipe leakage detection device comprises: the gas outlet of the gas tank is detachably connected with one end, located below the mine, of the bundle pipe through the gas guide pipe, at least six sulfur hexafluoride detectors are evenly distributed in the mine, and the sulfur hexafluoride detectors are fixedly connected with the inner wall of the mine.

Compared with the prior art, this disclosed beneficial effect does:

1. according to the method, sulfur hexafluoride gas which does not exist in the air basically is utilized to uniformly fix the sulfur hexafluoride detector on the mine, so that which section of the beam tube leaks can be determined, and then the accurate position of a leak point is further determined through the movable sulfur hexafluoride detector, so that the leak detection work of the beam tube can be rapidly carried out, the leak detection efficiency is higher, and the speed is higher and more accurate.
