AI Technical Summary

Technical Problem

During a tunnel fire, smoke quickly spread to the emergency passage, causing evacuation of personnel to be blocked and increasing the difficulty of emergency rescue.

Method used

A prefabricated high-performance component is designed, including a mounting frame, a powerful fan, a plug-in board, an expansion flap and a limiting assembly. Smoke is sucked in through a powerful fan and used the angle between the expansion flap and the plug-in plate to block the smoke. Combined with the limiting assembly and the traction assembly, it ensures that the expansion flap is quickly flipped when needed to form an angle to block the smoke.

Benefits of technology

Effectively prevent smoke from rapidly pouring into emergency channels, reduce smoke concentration in emergency channels, and improve the escape efficiency and safety of risk-averse personnel.

Abstract

The invention relates to the technical field of tunnel assembly type components, in particular to an assembly type high-performance component applied to a tunnel emergency channel, which comprises a mounting frame fixed at the top end of the tunnel emergency channel and close to an air outlet, a powerful fan is arranged at one end of the mounting frame, and a U-shaped bayonet socket is arranged at the lower end of the mounting frame. A U-shaped inserting plate is arranged at the position, close to the inserting base, in the mounting frame, a side edge inserting groove is formed in the outer side wall of the inserting plate, a limiting block is arranged at the position, close to the inserting plate, of the outer side wall of the mounting frame, and an expansion turning plate is arranged at the end, away from the powerful draught fan, of the inserting plate. According to the emergency channel, the expansion turning plate is arranged, smoke is blocked by means of the expansion turning plate, the smoke is sucked into the air outlet channel by means of the powerful draught fan, the smoke is effectively prevented from rapidly rushing into the emergency channel, the escape efficiency of danger avoiding personnel is improved, and the effect of avoiding smoke damage in a low posture is achieved.
