Dustproof smoke alarm equipment for large warehouse

Abstract

The invention belongs to the technical field of smoke alarms, and particularly relates to a dustproof smoke alarm device for a large warehouse, which comprises a shell and a probe arranged in the shell, a group of vent holes communicated with the probe are uniformly distributed on the circumference of the bottom of the shell; a circular ring is arranged at the bottom of the shell, and an umbrella-shaped drainage cover is fixedly connected to the bottom of the circular ring; during working, a smoke alarm device in a warehouse in the prior art is often mounted on a steel truss at the top, but when goods stored on a goods shelf in the warehouse are on fire and smoke is generated due to the fact that the clear height in the warehouse is high, the smoke is continuously diffused after rising, the concentration of the smoke is further reduced, and delay is generated after a probe detects the smoke. The fire response sensitivity of the alarm equipment is reduced; at the moment, smoke is converged and drained through the drainage cover, the efficiency of the smoke entering the shell is improved, the sensing sensitivity of the probe to the small-range smoke is further improved, early warning is further given out in time at the early stage of the fire, the fire extinguishing efficiency is improved, and losses are reduced.

Description

technical field [0001] The invention belongs to the technical field of smoke alarms, in particular to a dust-proof smoke alarm device for large warehouses. Background technique [0002] The principle of the smoke alarm is that the alarm unit in the smoke alarm detects smoke, and the smoke detector can make the internal buzzer sound, thereby warning the user to put out the fire in time and reduce fire losses. [0003] A Chinese patent with publication number CN107093307B discloses a miniature smoke alarm, which includes a base and a cover that moves axially along the base. The side wall of the cover is provided with a smoke inlet hole for smoke to enter the detection part. An elastic part is provided between the cover and the base to drive the cover away from the base through elastic action, and a limiting part is provided between the cover and the base to limit the detachment of the cover from the base through abutting action, and the control The side of the circuit board f...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the smoke alarm device in the warehouse is often installed on the steel truss at the top, but due to the high net height in the warehouse, when the goods stored on the shelves in the warehouse catch fire and generate smoke, the smoke rises and spreads continuously, thereby reducing the smoke. The concentration of the smoke makes the detector delay after detecting the smoke signal and reduces the response sensitivity of the alarm equipment to the fire.
