Detailed Description
Referring to fig. 1 and 2, the water-gas separation detection structure provided in this embodiment is mounted at an air inlet end of a gas detector (not shown in the drawings), and includes a floating ball 1, a plurality of air inlets 2 are formed on a surface of the floating ball 1, the air inlets 2 are mutually communicated, and the interior of the floating ball 1 is divided into a plurality of closed cavities 3 by the air inlets 2, wherein one air inlet 2 is connected with the air inlet end of the gas detector through an air pipe 4, the number of the air inlets 2 is set to 3-14, and an arc length between two adjacent air inlets 2 is 0.5R-3.14R, wherein R is a radius of the floating ball 1.
It should be noted that, this embodiment has improved the mode of breathing in of traditional gas detector, carries out the sampling of detecting gas through the floater 1 structure, when the environment of waiting to detect gas is unknown environment, water condition or dark or shallow, or there is the stormy waves, can directly throw the one end that has floater 1 to the surface of water, floater 1 floats on the surface of water, and guarantees that there is inlet port 2 to spill on the surface of water, because the density of air is far less than the density of water, through the suction of control gas detector air pump, can realize the quick extraction to surface of water gas, high-efficient realization water-gas separation, prevent to draw into gas detector with water, influence the testing result, play good protection to gas detector, easy operation is convenient.
