Background

The mine harmful gas refers to gas harmful to human bodies in mines. Mainly carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur dioxide, ammonia, etc., and explosive gases such as biogas (methane), hydrogen, and methane homologues (ethane, propane, etc.). The main component of harmful gas in coal mine is methane. Wherein the carbon dioxide (carbon dioxide) is a carbon oxide with the chemical formula of CO2, the chemical formula of 44.0095, is a colorless and tasteless or colorless and tasteless (smelling no smell) but slightly sour gas at normal temperature and normal pressure, is also a common greenhouse gas, and is one of the components of air (accounting for 0.03-0.04 percent of the total volume of the atmosphere). In terms of physical properties, carbon dioxide has a melting point of-56.6 deg.C, a boiling point of-78.5 deg.C, a density greater than that of air (under standard conditions), and is soluble in water. Carbon dioxide is chemically inert, highly thermally stable (only 1.8% decomposition at 2000 ℃), nonflammable, generally nonflammable, an acidic oxide, and a common acidic oxide, and is an acid anhydride of carbonic acid due to the reaction with water to produce carbonic acid. But some mines with excessive carbon dioxide levels have an irritating risk.

SUMMERY OF THE UTILITY MODEL

The utility model provides a gaseous detection device of portability aims at solving the problem that has the risk of puzzling in the mine that some carbon dioxide concentration exceed standard.

The utility model discloses a realize like this, a gaseous detection device of portability, a serial communication port, transparent box body and lid are connected, the box body with the rubber packing ring is installed to the lid contact surface, be formed with the handle on the lid, box body inner wall left end face is formed with the through-hole, first rubber buffer is installed on the through-hole right side, wear to be equipped with first pipe in the first rubber buffer, first pipe is kept away from the one end of first rubber buffer extends to transparent container bottom, first pipe is worn to locate in the bottle plug, the bottle plug with the bottle plug container is connected, wear to be equipped with the second pipe in the bottle plug, the second pipe is kept away from the rubber tube is passed through to the one end of bottle plug and is connected with the air pump air inlet, the air pump is fixed in box body inner wall right-hand member face, the box body right-hand member face is.

Furthermore, the box body is made of transparent acrylic.

Still further, the container is a erlenmeyer flask.

Furthermore, a second rubber plug is installed at one end, far away from the first rubber plug, of the through hole.

Further, the air pump is a manual air pump.

Further, the box body and the cover body are connected through bolts.

The utility model discloses the beneficial effect who reaches: through the mutual cooperation of all mechanisms, the problem that some mines with excessive carbon dioxide concentration have suffocating risks is solved, as the first conduit penetrates through the first rubber plug, one end of the first conduit, which is far away from the first rubber plug, extends to the bottom of the transparent container, the first conduit is arranged in the bottle stopper in a penetrating way, the bottle stopper is connected with the container, the second conduit is arranged in the bottle stopper in a penetrating way, one end of the second conduit far away from the bottle stopper is connected with an air inlet of the air pump through a rubber tube, the second conduit penetrates through the bottle stopper, one end of the second conduit far away from the bottle stopper is connected with the air inlet of the air pump through a rubber tube, therefore, under the action of the air pump, the gas of the tested environment can fully contact and react with the calcium hydroxide solution in the container to generate calcium carbonate precipitate which can be clearly seen by naked eyes, and the concentration of carbon dioxide can be laterally reflected according to the amount of the precipitate.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the working principle of the manual air pump is the prior art, and belongs to the common general knowledge of those skilled in the art, and therefore, the detailed description thereof is omitted here.

Referring to fig. 1, fig. 2 and fig. 3, a portable gas detection device, a transparent box 1 is connected with a cover 3, a rubber gasket 2 is installed on the contact surface of the box 1 and the cover 3, a handle 301 is formed on the cover 3, a through hole 101 is formed on the left end surface of the inner wall of the box 1, a first rubber plug 4 is installed on the right side of the through hole 101, a first conduit 6 is arranged in the first rubber plug 4 in a penetrating manner, one end, far away from the first rubber plug 4, of the first conduit 6 extends to the bottom of a transparent container 8, the first conduit 6 is arranged in a bottle plug 7 in a penetrating manner, the bottle plug 7 is connected with the container 8, a second conduit 9 is arranged in the bottle plug 7 in a penetrating manner, one end.

The box body 1 is made of transparent acrylic material, and the acrylic material has good transparency, chemical stability and weather resistance.
