Fire-fighting and fire-extinguishing reconnaissance robot for hazardous chemical space

Abstract

The invention relates to the technical field of fire-fighting robots, and provides a fire-fighting and fire-extinguishing reconnaissance robot for a hazardous chemical space. The fire-fighting and fire-extinguishing reconnaissance robot for the hazardous chemical space comprises a chassis and an advancing mechanism, and further comprises a reel, a tripod head, a camera, a thermal infrared imager and a damping mechanism, wherein the reel is mounted on the chassis and used for carrying a cable; the tripod head is mounted on a supporting shaft; the camera and the thermal infrared imager are carried on the top of the tripod head; and the damping mechanism is arranged between the supporting shaft and the tripod head. According to the fire-fighting and fire-extinguishing reconnaissance robot for the hazardous chemical space, the autonomous navigation type robot walking chassis is designed, a fire source is found through the camera carried by the tripod head, fire extinguishing is conducted through fire-fighting bubbles, and meanwhile the field condition can be mastered in real time through the thermal infrared imager; the two-way damping mechanism composed of a large damping pad and a small damping pad is designed for the tripod head of the fire-fighting robot, and vibration generated in different directions can be greatly counteracted; and the reel carrying the cable is designed on the chassis of the fire-fighting robot, charging can be achieved anytime and anywhere, the robot can still work uninterruptedly in the charging process, and the endurance level of the robot is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting robots, in particular to a fire-fighting and reconnaissance robot for hazardous spaces. Background technique [0002] Due to the frequent occurrence of fire accidents in our country in recent years, the work in the field of fire protection has attracted more and more attention from all walks of life. In the very harsh environment of the fire scene, firefighters will face great difficulties in the process of fire fighting and rescue work. They must be in an environment with high temperature and high concentration of toxic and harmful gases, which seriously threatens the life safety of firefighters. In this case, the application of fire-fighting robots can solve this problem to the greatest extent. Robots can replace firefighters to carry out certain dangerous tasks, and can gain valuable time in the intense fire-fighting and rescue process to ensure the smooth progress of rescue tasks.

Problems solved by technology

[0006] However, the pan-tilt and the connecting shaft of the existing fire-fighting robot are connected by an integrated shock-absorbing rubber pad. During the walking process of the robot, the camera, infrared heat The imager and other equipment have a large weight, and the vibration at any time will affect the stability of the gimbal, especially during the obstacle crossing process, which will generate a large lateral bending moment on the shock-absorbing pad, which will easily cause the shock-absorbing pad to tear. The gimbal will be dropped and damaged, which will affect the service life

[0007]On the other hand, fire-fighting robots suitable for hazardous chemical spaces have more electrical equipment, and equipment such as movement, obstacle avoidance, image acquisition, and infrared imaging all require power sources Power supply. In the prior art, most fire-fighting robots use larger lithium batteries for power supply. Using smaller lithium batteries cannot meet the requirements for battery life and power supply time. Using larger lithium batteries will increase the weight of the device, and the walking of the fire-fighting robot Energy consumption will increase. On the other hand, a larger lithium battery will increase the volume of the device, which will affect the passing performance and obstacle climbing ability of the firefighting robot.

[0008] Therefore, a fire-fighting robot for hazardous chemical spaces is developed to replace firefighters entering dangerous accident sites such as flammable, explosive, toxic, hypoxic, and dense smoke , effectively solve the problems faced by firefighters in the above places such as insufficient power, poor image and data information collection stability, etc.
