Intelligent smoke exhaust device and smoke exhaust method based on shape memory alloy
By using a grating plate made of shape memory alloy, cracks are automatically opened to form a smoke exhaust channel based on temperature changes, which solves the problems of power supply failure and slow mechanical response in existing electric smoke exhaust windows, and achieves a highly efficient automatic smoke exhaust effect.

AI Technical Summary
Technical Problem
Existing electric smoke exhaust windows are at risk of power failure, and mechanical temperature sensing elements are slow to respond and cannot respond to fire risks in a timely and effective manner, resulting in untimely smoke exhaust.
Method used
The grating is made of shape memory alloy, which deforms at 90°C and opens pre-set cracks to form a smoke exhaust channel, and automatically resets after cooling.
Benefits of technology
It enables timely and effective smoke extraction during a fire, solving the problems of slow response and manual reset, and has a highly efficient automated smoke extraction function.

Abstract
The invention relates to the technical field of building fire protection, in particular to an intelligent smoke exhaust device based on shape memory alloy and a smoke exhaust method.The intelligent smoke exhaust device comprises a window frame installed on a wall and a grating plate embedded into the window frame, and the grating plate is manufactured by laser etching of a shape memory alloy matrix with a preset crack pattern; and a heat reflection coating is arranged on the surface of the grating plate. When no fire occurs, the grating plate is in a sealed state, and no gap exists; when a fire disaster occurs, the indoor temperature rises rapidly, when the temperature rises to 90 DEG C and reaches the deformation temperature of the memory alloy, deformation begins, cracks are opened after the grating plate deforms, the preset cracks are distributed in a radial mode after being opened, a smoke exhaust channel is generated, and indoor smoke dust is exhausted. The method has the technical effects of high response speed and no need of manual reset.
