A safety detection and alarm device for workshop

Abstract

The invention discloses a safety detection and alarm device used in a workshop, comprising a gas detection box, a controller is installed on the outer surface of the gas detection box, an alarm device is arranged outside the gas detection box, and the gas detection box is There is a high-precision gas detection device inside, and an air circulation device is installed on the high-precision gas detection device; the sealing piston is driven by an electric telescopic rod to pump air, and then the lower baffle is pushed up and down by a small electric telescopic rod, so as to detect The gas inside the square detection box, and through the sealing connection between the upper sealing baffle and the lower sealing baffle and the detection sleeve, the electrochemical poison gas sensor can be effectively isolated, so as to ensure the accuracy of gas detection; It can be used to extract air, so that the air in the air intake pipe network and the L-shaped air circulation pipe can be quickly replaced. The beneficial effects of the invention are that the operation is simple and the practicability is strong.

Description

technical field [0001] The invention relates to the field of safety detection related equipment, in particular to a safety detection alarm device used in a workshop. Background technique [0002] The gas detection instrument currently used has its own buzzer, but the buzzer is small and the sound is very small. When used in the workshop, the noise of the workshop itself is too loud and it is easy to not hear the sound, and the high-power buzzer is generally It is difficult to install on the gas detection instrument and needs to be installed separately. Therefore, when the instrument detects an abnormal concentration of poisonous gas, it is also more troublesome to control the additionally installed buzzer. [0003] In the patent CN201821822596.3-a workshop poisonous and harmful gas leakage detection and alarm device, when the poison gas sensor detects the abnormal concentration of poison gas in the workshop and transmits a signal to the controller, the controller can control...

Problems solved by technology

[0004] However, due to the large internal space of the workshop, although the above-mentioned patents can effectively detect toxic and harmful gases, the detection range is too small to accurately and quickly detect the gas conditions inside the workshop.
