As shown in fig. 1, the present embodiment provides a methane sensor air chamber for mining, including: the device comprises an inner circular protective cover 1, an inner dustproof water retaining star-shaped sheet 2, an outer circular protective cover 3 and an outer dustproof water retaining cover 4 from inside to outside in sequence;
the outer circular protective cover 3 covers the inner circular protective cover 1, and the inner dustproof water retaining star-shaped sheet 2 is arranged between the inner circular protective cover 1 and the outer circular protective cover 3; the dustproof water-retaining star-shaped sheet is fixed on the outer circular protective cover 3 through a clamp spring, and a certain gap is reserved between the inner dustproof water-retaining star-shaped sheet 2 and the outer circular protective cover 3 and is used as an air guide groove; the outer circular protective cover 3 is provided with a vent hole 31; an air vent 11 is arranged at the bottom of the inner circular protective cover 1, a circular copper filter plate 6 is arranged on the air vent 11, and a gas catalytic sensor 5 is placed in the inner circular protective cover 1; the outer dustproof water shield 4 is fixed at the vent hole 31 at the bottom of the outer circular protective cover 3 through jackscrews.
In the following, the principles of the present application are described in detail, with the air chamber being generally impacted by water, either from the bottom up against the housing side of the air chamber, or laterally from the housing side. When water with certain pressure is impacted from the bottom of the air chamber, the water can be blocked for the first time by the outer dustproof water retaining cover 4 and flows away all around, but still a part of water still can enter between the outer dustproof water retaining cover 4 and the outer circular protective cover 3 through the circular holes 41 of the outer dustproof water retaining cover 4, because the circular holes 41 of the outer dustproof water retaining cover 4 are staggered with the vent holes 31 of the outer circular protective cover 3, most of water flows out of the elliptical holes on the side surface of the outer dustproof water retaining cover 4, the water pressure is further reduced, certain water still flows into the outer circular protective cover 3, the inner dustproof water retaining plate 2 is structurally designed, only a vent hole 31 with certain size and quantity is formed around the outer circular protective cover 3, the inner dustproof water retaining plate 2 and the outer circular protective cover 3 form a gas guide groove, the water after being impacted to the inner dustproof water retaining plate 2 through the reduced pressure is blocked again, and a small part of the water enters into the inner circular protective cover 2 through the gas guide groove, and the water retaining plate 2 has certain pressure, so that the water level of the inner dustproof water retaining plate 2 can not normally feel that the air chamber is blocked by the air chamber, and the water level of the inner dustproof water retaining cover is not normally sensed by the air chamber 5.
When water with a certain pressure impacts from the middle part of the air chamber, the air holes are generally arranged transversely, and the transverse water impacts, so that a small amount of water can flow into the air chamber through the air holes 31 of the outer circular protective cover 3, and the Kong Xiaohui can block part of the water pressure, so that the water quantity entering the air chamber is very small. Furthermore, due to the protection function of the inner circular protective cover 1, water cannot be directly splashed onto the gas catalytic sensor 5, and the working temperature of the gas catalytic sensor cannot be changed, so that the gas catalytic sensor 5 can work stably.
In the embodiment, the copper filter 6 has better osmotic filtering performance, and the equipment has better performance of bearing thermal pressure and impact and longer service life.
In one implementation, a sensor circuit board 7 is arranged below the gas catalytic sensor 5 in the inner circular protective cover 1; the upper and lower surfaces of the sensor circuit board are respectively provided with a layer of latex pad 8. In the embodiment, the latex pad 8 is arranged to buffer the external force applied to the sensor circuit board 7, so that the damage to components and parts of the sensor circuit board 7 is avoided.
In one implementation, the circular copper filter 6 has a thickness of 2mm; the latex pad 8 has a thickness of 1mm. The proper thickness is favorable for playing the roles of the circular copper filter 6 and the latex pad 8, and meanwhile, the reasonable distribution of the air chamber space can be ensured.
In one implementation, the gas catalytic sensor 5 is a methane sensor.
In one implementation, the inner circular shield 1 is a plastic circular shield. The circular protective cover made of plastic can effectively block moisture as the last defending line of the air chamber.
