Problems solved by technology

In fact, large particles of dust exceeding PM2.5 in the air are also harmful to human health. Inhaling too much large particles of dust can also cause respiratory diseases, but the detection of PM2.5 will filter large particles of dust and cannot be clearly detected The content of large particles in the air
Therefore, the detection of the particle content in the air cannot be filtered, and the detection of particles in the air will be affected after filtering large particles

Embodiment

[0024] as attached figure 1 As shown, a gas-assisted detection device includes a bracket and a box body 1. The box body 1 is fixed on the bracket by fastening bolts. The box body 1 is provided with an inner cavity 6 and a hollow air intake rod 2 communicating with the inner cavity 6. .

[0025] The air intake rod 2 is located on the upper part of the box body 1, and the side wall of the air intake rod 2 is provided with an annular chamber 3, and the inner wall of the annular chamber 3 is provided with an air inlet 4 inclined downward toward the inner chamber 6, and a high-pressure gas tank is fixed on the bracket 20. The high-pressure gas tank 20 communicates with the annular chamber 3 through a solenoid valve. The air intake rod 2, the annular chamber 3 and the air inlet 4 form an air amplifier, and high-pressure gas is introduced into the annular chamber 3 and runs from the air inlet 4. It will speed up the flow of air. The two side walls of the inner cavity 6 are provided...

Abstract

The invention belongs to the technical field of safety protection, and discloses a gas auxiliary detection device. The gas auxiliary detection device comprises a support and a tank body; the tank bodyis fixedly arranged on the support, and is provided with an internal cavity and a gas inlet rod; the gas inlet rod is provided with an annular chamber; the annular chamber is provided with a gas inlet; a high pressure gas tank is fixedly arranged on the support; the two side walls of the internal cavity are provided with blocking plates and air bags; a first chain wheel is fixedly arranged on a rotating shaft; the bottom of each blocking plate is provided with an infrared lamp; the bottom of the internal cavity is provided with an opening and a detection box; the detection box is provided with a first glass plate; a photoresistor is arranged in the detection box; the photoresistor is connected with an indicating lamp through electric connection; the support is provided with internally meshed ratchet wheel structure; the internally meshed ratchet wheel structure comprises an outer ratchet wheel, a driving ratchet wheel, a non-return ratchet wheel, and a driving wheel; a second chain wheel is fixedly arranged in the driving wheel; the outer rim of the outer ratchet wheel is fixedly provided with a rotating disc; the rotating disc is provided with a second glass plate; the second glass plate is provided with a transparent adhesive tape; and the adhesive surface of the transparent adhesive tape is arranged to be toward the internal cavity. The gas auxiliary detection device is simple in structure, and is capable of realizing air detection without filtering particles.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a gas auxiliary detection device. Background technique [0002] Air, commonly known as "life gas", we need to breathe every day. However, the air contains different amounts of impurities in different environments. These impurities are undoubtedly harmful to the human body. We cannot see them with the naked eye. We need a detection device to detect whether the impurity content in the air is harmful to human health. [0003] Generally, the detection of gas is the detection of PM2.5, and it is believed that PM2.5 is the standard for judging the harmfulness of human body. In fact, large particles of dust exceeding PM2.5 in the air are also harmful to human health. Inhaling too much large particles of dust can also cause respiratory diseases, but the detection of PM2.5 will filter large particles of dust and cannot be clearly detected The content of large particles in the...
