Embodiment 1

[0032] Such as Figure 1 to Figure 2As shown, a dust-proof and smoke-proof alarm device for a large warehouse according to the embodiment of the present invention includes a housing 1 and a probe 11 placed in the housing 1; Connected ventilation holes 12; the bottom of the housing 1 is provided with a ring 13, and the bottom of the ring 13 is fixedly connected with an umbrella-shaped drainage cover 14; during work, the smoke alarm device in the warehouse in the prior art is often installed on the top of the steel On the truss, but due to the high clear 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 concentration of the smoke, making the probe 11 delay after detecting the smoke signal and reducing the alarm. Response sensitivity to equipment fires; at this time, the present invention increases the efficiency of smoke entering the casing 1 through the con...

Embodiment 2

[0041] Such as Figure 7 to Figure 8 Shown, comparative example one, wherein another kind of implementation mode of the present invention is:

[0042] Foldable wings 36 are fixedly connected to both sides of one end of the stay cord 15 close to the fan-shaped disk 21, and a group of elastic ribs 37 are embedded in the wings 36; Driven by the umbrella rib 37, it is deployed to form a windshield wall, reducing the smoke from being blown away by the cross wind when it passes through the space between the ring 13 and the housing 1. so that there is no wing 36 near the housing 1 when the pull cord 15 is fully released, thereby reducing the obstruction of smoke from other parts of the warehouse top and further increasing the sensing area of ​​the probe 11.

[0043] The outer edge of the wings 36 is provided with flexible magnetic strips 38, and the fixed magnetic strips 38 on the wings 36 between adjacent stay cords 15 attract each other; The airtightness surrounding the cylinder ...

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...
