AI Technical Summary

Technical Problem

The existing fire alarm devices cannot effectively clean up smoke and dust entering the alarm during the detection process, resulting in a decrease in the reliability of the detection results.

Method used

An electrical fire alarm device for building is designed, which uses the upward movement of the piston plate to detect the gas. Then, the electrostatic plate is used to absorb dust, drive the rack movement through the gears to scrape the dust, and the dust is concentrated and stored in the dust collecting block through the cooperation of the magnetic plate and the wedge block, and finally the dust is discharged through the airflow.

Benefits of technology

The dust and smoke particles in the detection frame are effectively cleaned up, which improves the accuracy and reliability of the detection results, and ensures the quality of the detection results in multiple rounds of detection.

Abstract

The invention relates to a building electrical fire-fighting alarm device applied to the field of fire-fighting alarm, a piston plate moves upwards to play a suction role, so that after external gas is transferred into a detection frame to be detected, dust and smoke particles entering the detection frame are adsorbed by an electrostatic plate, and then the dust and smoke particles enter the detection frame. Then a gear is used for driving a first rack and a second rack to move oppositely, dust and smoke particles adsorbed on the surface of an electrostatic plate are scraped and cleaned, and through extrusion treatment on the top end of a dust collecting block when a wedge-shaped block approaches, a magnetic moving plate moves upwards to expose a through groove, and dust pushed when an opposite block approaches is collected into the dust collecting block; afterwards, the dust collection block is sealed by utilizing the automatic falling of the magnetic moving plate, then the gas part in the detection frame is discharged by utilizing the falling of the piston plate, and the dust and smoke particles in the dust collection block are discharged by utilizing the air flow during discharging.
