AI Technical Summary

Technical Problem

The photoelectric support column of existing fire inspection robots has a fixed height and cannot be adjusted according to actual needs, which limits the monitoring range and affects the accuracy and timeliness of fire early warning.

Method used

A lifting column module was designed, which uses a servo motor to drive a trapezoidal lead screw. The column is flexibly raised and lowered through a nut and threaded connection. Combined with inner and outer guide sleeves and sealing gaskets, stability and protection are ensured. It is equipped with a dual-spectrum camera and a fire extinguishing spray pipe.

Benefits of technology

It enables precise adjustment of monitoring height according to different inspection scenarios and spatial heights, expands the monitoring field of view, eliminates monitoring blind spots, and improves the ability to detect fire hazards and the accuracy of early warning.

Abstract

This utility model discloses a lifting column module, relating to the field of fire safety technology. The module features a lifting column supported by a base, with a motor-driven lead screw that raises and lowers the column via a nut. A guiding reinforcement device and a sealing structure ensure stability and reliability. A base plate is installed at the top of the column to secure a dual-spectrum camera and fire extinguishing nozzle, and also includes power and communication sockets. An industrial drive board is installed at the bottom of the base to control the motor's operation. This module allows for flexible height adjustment of the dual-spectrum camera through the lifting column, effectively expanding the monitoring range, eliminating blind spots, improving the fire inspection robot's ability to detect fire hazards and its accuracy in early warning, and enhancing its adaptability and practicality in complex environments.
