Automatic spraying equipment with high-sensitivity gas sensing function

Abstract

The invention belongs to the technical field of fire-fighting equipment, and particularly relates to automatic spraying equipment with a high-sensitivity gas sensing function. The automatic spraying equipment comprises a mounting shell, a piston and a spray head, wherein the spray head is arranged on the right side face of the mounting shell, and a guide pipe is fixedly connected to the interior of the mounting shell; a sealing plate is fixedly connected to the interior of the guide pipe, and rotating groove is formed in the position, close to the side face of the sealing plate, of the upper surface of the sealing plate; a rotating block is rotatably connected to the interior of the rotating groove, and an air cylinder groove is formed in the rotating block; and a piston is connected to the interior of the air cylinder groove in an up-down sliding mode. According to the automatic spraying equipment, the automatic compression of low-concentration smoke gas is effectively realized, and the distance between adjacent smoke particles is reduced and the smoke concentration is increased due to the reduction of the volume of the compressed low-concentration smoke gas; and at the moment, asmoke sensor can directly detect the low-concentration smoke to realize a rapid alarm, and the detection sensitivity of the smoke sensor is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to high-sensitivity gas-sensing automatic spraying equipment. Background technique [0002] The smoke detector realizes fire prevention by monitoring the concentration of smoke. The ion smoke sensor is used inside the smoke detector. The ion smoke detector is a sensor with advanced technology and stable and reliable operation. It is widely used in various fire alarm systems. , The performance is far superior to the fire alarm of the gas sensitive resistance class. [0003] According to CN209842842U smoke sensor, it is used for smart home equipment to detect the smoke concentration of the place around the clock. When the smoke gas concentration reaches 100ppm, the product will alarm. It can be installed at home, office, factory and other places for remote monitoring, so as to know the smoke concentration. Local smog and gas conditions, early detection of smog, recove...

Problems solved by technology

[0004] But in the prior art, when the smoke detector detects the smoke, when the initial stage of the fire occurs, the smoke concentration is low, especially when the fire occurrence point is far away from the smoke detector, even if the fire has already occurred, the smoke floats to the vicinity of the smoke detector , has been fully dispersed in the air, and the smoke concentration is greatly reduced. Since the smoke device needs to reach the smoke alarm concentration, it can be triggered. The sensitivity of the smoke device is low, and it is difficult to meet the rapid warning of fire, especially when the fire point is far away. Early warning and other issues
