Mechanical hand dedicated to automatic device for on-site fire rescue

Abstract

The invention relates to a mechanical hand dedicated to an automatic device for on-site fire rescue. The mechanical hand comprises a redundant parallel mechanism and a fire extinguishing device, wherein the redundant parallel mechanism is right below the fire extinguishing device; and the upper end of the redundant parallel mechanism is connected with the fire extinguishing device. According to the invention, the mechanical hand has multiple functions like direction adjustment and fire extinguishing and can perform fire extinguishing on a fire scene, the automation degree is high, the motion is stable and flexible during fire extinguishing, the fire extinguishing ejection range is large, the fire extinguishing efficiency is high, the safety is high, and the problem that manual fire extinguishing is low in efficiency and is highly dangerous is solved; and the redundant parallel mechanism adopts a 2-UPS-2-RPS parallel mechanism, and can move in four degree-of-freedom directions, namely, the parallel mechanism can move along the X axis and the Z axis and can rotate around the X axis and the Y axis, so that on one hand, the direction and angle of the fire extinguishing device are adjusted, and on the other hand, a vibration damping effect is achieved on the fire extinguishing device, and the problem that a stored fire extinguisher has potential safety hazards due to too severe shaking is prevented.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a special-purpose manipulator for automatic fire rescue equipment. Background technique [0002] Fire refers to burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threatens public safety and social development; fire hazards exist in many occasions and industries, such as chemical industry Factories, family residences, public shopping malls, gas stations, power companies, smelters, etc.; there are many reasons for fires, such as violations of electrical safety regulations, violations of safe operation regulations, littering of cigarette butts, and spontaneous combustion. [0003] At present, there are many kinds of fire extinguishers used in fire fighting, mainly carbon dioxide fire extinguishers, 1211 fire extinguishers, dry powder fire extinguishers, acid-reduced foam fire extinguishers, car...

AI Technical Summary

Problems solved by technology

[0004] For fire fighting and fire extinguishing methods, manual fire extinguishers are often carried into the fire fighting site for manual fire fighting operations. Such existing fire fighting methods are dangerous and pose a great threat to the personal safety of firefighters. There are a lot of people who died in firefighting operations; at the same time, the efficiency of manual on-site firefighting operations will gradually decrease with the prolongation of the operation time, and the overall efficiency, speed and flexibility of firefighting operations are low.
