A fire detection and fire fighting robot and its working method

Abstract

The invention discloses a fire-fighting reconnaissance and fire-extinguishing robot, which comprises a crawler chassis, a fire-fighting water cannon and a reconnaissance mechanism. Both the fire-fighting water cannon and the reconnaissance mechanism are arranged on the crawler chassis. Driving wheel, driven wheel set, supporting pulley set, load-bearing wheel set, shock absorbing plate set, elastic element, approaching wheel set, tensioning mechanism, obstacle avoidance component, warning component, drive component, controller, wireless transmission component, track It is composed of components, dust cover, searchlight and lithium battery. It solves the problem of slipping and falling off between the driving wheel and the track, realizes the efficient transmission between the driving wheel and the track, ensures the adhesion performance of the suspension system to the track during the obstacle surmounting process, and can also improve the stability of the robot when climbing over obstacles. It realizes the tension function of the upper suspension system of the robot, further improves the safety and stability of the robot movement, and reduces the maintenance difficulty and application cost of the robot.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a fire-fighting reconnaissance and fire-extinguishing robot and a working method thereof. Background technique [0002] Firefighters have many disadvantages in the rescue or investigation of accident sites such as high-risk fires, and the application of fire detection and fire fighting robots was born. The fire reconnaissance and fire extinguishing robot can replace the firefighters to realize the fire extinguishing function in the periphery. At the same time, removing the hose can replace the firefighters to enter the dangerous disaster accident scene to realize the reconnaissance and even rescue functions, so the development prospect is broad. [0003] However, on the one hand, the on-site environment in fire and other scenes is extremely harsh, especially there are many obstacles on the ground or in space, which poses a huge challenge to the robot's obstacle-surmoun...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a fire-fighting reconnaissance and fire-fighting robot. Aiming at the driving efficiency and stability of the current driving wheel and crawler belt, the high-efficiency transmission function between the driving wheel and the crawler belt is realized through the gear-shaping driving wheel and the matching crawler belt; Insufficient climbing and obstacle performance of the system, by designing a double-row and double-row composite approach wheel to ensure the fit performance of the suspension system and the track during the obstacle-crossing process, the robot’s obstacle-climbing and climbing ability is significantly improved; for the tension of the robot suspension system The disadvantages of the mechanism, through the wedge-shaped tensioning mechanism, the tensioning function of the upper suspension system of the robot is realized to ensure the tightness of the robot's track movement, thereby further improving the safety and stability of the robot's movement and reducing the difficulty of robot maintenance
