A multi-degree-of-freedom knife-moving device for high-pressure water jet

Abstract

The invention belongs to the technical field of fire-fighting equipment and particularly relates to a multiple-degree-of-freedom feeding device based on high-pressure water jet. The multiple-degree-of-freedom feeding device comprises an adjustable bracket and a feeding mechanism, wherein the adjustable bracket comprises supporting legs, locking blocks and a horizontal support; the supporting legs are connected with the horizontal support by the locking blocks; the feeding mechanism comprises a horizontal swing rod mechanism, a horizontal swing rod electric push rod, longitudinal swing rod mechanisms, a longitudinal swing rod electric push rod, a spray gun electric push rod, a high-pressure water jet spray gun and longitudinal fixing rods; the longitudinal swing rod mechanisms are connected with the horizontal support through the longitudinal fixing rods; one end of the longitudinal swing rod electric push rod is connected with one longitudinal fixing rod; the other end of the longitudinal swing rod electric push rod is connected with the longitudinal swing rod mechanisms; one end of the horizontal swing rod electric push rod is connected with the longitudinal swing rod mechanisms; the other end of the horizontal swing rod electric push rod is connected with the horizontal swing rod mechanism; one end of the spray gun electric push rod is fixed on the horizontal swing rod mechanism; and the other end of the spray gun electric push rod is connected with the high-pressure water jet spray gun. The invention provides a multiple-degree-of-freedom feeding mechanism capable of controlling at a far end; and the multiple-degree-of-freedom feeding mechanism can be used for cutting dangerous goods such as suspected explosives, and has important practical significance for safely executing counter-terrorism mission by fire fighting forces.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a high-pressure water jet multi-degree-of-freedom cutting device. Background technique [0002] In the fight against terrorism, the fire brigade undertakes the task of rescuing and disposing of the scene of terrorist incidents and doing its best to rescue people in distress. However, the scene of a terrorist incident is often complicated and a variety of disasters occur side by side, such as: fire, leakage of dangerous chemicals, bomb explosion, collapse of buildings, etc., and there are great potential safety hazards. [0003] At the same time, for fires in confined spaces such as underground spaces and transportation vehicles, if the traditional demolition method is used, if the timing or method is not selected properly, a large-area ventilation channel will suddenly be formed, causing a large amount of fresh air to be involved in the combustion In ...

However, the scene of a terrorist incident is often complicated, with multiple disasters occurring side by side, such as: fire, leakage of dangerous chemicals, bomb explosion, collapse of buildings, etc., and there are great potential safety hazards

[0003] At the same time, for fires in confined spaces such as underground spaces and transportation vehicles, if the traditional demolition method is used, if the timing or method is not selected properly, a large-area ventilation channel will suddenly be formed, causing a large amount of fresh air to be involved in the combustion In the hot air, it is easy to form flashover, which will seriously threaten the life safety of firefighters

On the other hand, the rescue tools commonly used by firefighters on the fire scene are mainly some ordinary manual or motorized (including electric, hydraulic, etc.) rescue tools. Large, relatively cumbersome process, long operation time, especially for flammable and explosive occasions, it is difficult to play an effective role
