AI Technical Summary

Technical Problem

Existing LED display power supplies lack active protection mechanisms, resulting in a high risk of overheating and spontaneous combustion, which can easily lead to fire accidents. Traditional passive heat dissipation and overcurrent protection cannot effectively prevent power supply overheating and spontaneous combustion.

Method used

The fire extinguishing liquid pipe is made of a material with a preset melting point. A circuit is formed between the conductive coating and the metal conductive sheet. When the temperature reaches the melting point, the circuit is cut off and inert gas is released to extinguish the fire. The integrated circuit integrates the functions of cutting off and extinguishing the fire, providing a rapid response.

Benefits of technology

It enables the rapid cutoff of power supply to the fire source and reduces oxygen concentration in confined spaces, thus quickly extinguishing the fire and reducing property damage and threats to personal safety.

Abstract

The invention belongs to the technical field of LED display screens, and particularly relates to a fireproof device, a power module and an LED display screen, the fireproof device comprises a fire extinguishing liquid pipe, a fire extinguishing pipe fixing rubber sleeve, a wire holder, a wire inlet end and a wire outlet end; the outer surface of the fire extinguishing liquid pipe is coated with a conductive coating, and the fire extinguishing liquid pipe is placed on the fire extinguishing pipe fixing rubber sleeve; a metal conducting strip is arranged on the fixed fire extinguishing tube rubber sleeve and is electrically connected with the wire inlet end and the wire outlet end respectively; when the fire extinguishing liquid pipe is placed on the fire extinguishing pipe fixing rubber sleeve, the conductive coating is in contact with the metal conductive sheet to form a conduction circuit; the fire extinguishing liquid pipe is made of a meltable material with a preset melting point, when the environment temperature reaches the preset melting point, the fire extinguishing liquid pipe is broken, a conduction circuit is cut off, and fire extinguishing liquid packaged in the fire extinguishing liquid pipe is instantly gasified into inert gas to cover a protection area to achieve fire extinguishing. Through melting triggering of the fire extinguishing liquid pipe, the circuit cutting-off function and the fire extinguishing function are integrated into the same device, and quick response is achieved.
