Description

Technical Field

[0001] The invention relates to the technical field of conveyor fire protection, in particular to a fire protection sprinkler device for a belt conveyor material guide trough. Background Art

[0002] In modern industrial production, belt conveyors, as one of the main equipment for material transportation, are widely used in many industries such as mining, metallurgy, coal, chemical industry, and building materials. During the operation of the belt conveyor, the trough part of the belt conveyor often generates high temperature due to material friction, accumulation, and other reasons, and may even cause fire accidents, posing a serious threat to production safety and the safety of life and property of personnel. Moreover, most companies design their boilers to burn lignite, which has the characteristics of high moisture content, high volatility, and easy spontaneous combustion. The belt conveyor trough is a closed structure, and personnel cannot observe all the internal conditions, which may cause spontaneous combustion caused by accumulated coal and cause unsafe incidents. The original design did not have a fire sprinkler in the trough, and coal powder was easily accumulated in the trough, which was difficult to clean, and easily caused spontaneous combustion and fire, which was not conducive to safe production;

[0003] Traditional firefighting measures mainly rely on manual inspections and fixed fire sprinkler devices. However, manual inspections have disadvantages such as long inspection cycles and slow response speeds, making it difficult to detect and deal with fire hazards in a timely manner. Fixed fire sprinkler devices can reduce fire risks to a certain extent, but due to their fixed spraying range and angle, they often cannot cover all corners of the guide chute, resulting in poor spraying effects.

The meshing transmission of spur gear 1 408 makes spur gear 2, rotating water, spray head and infrared thermometer 503 rotate synchronously to the target angle.
