The invention relates to a magnetomotive braking structure and a load releasing device. The magnetomotive braking structure comprises a piston cylinder; an air pressure release structure; the magnetic transmission device is driven by high-pressure gas and moves along the side wall of the piston cylinder, and the magnetic transmission device structurally comprises an outer magnetic ring group and an inner magnetic ring group which have magnetism; and the brake conductor ring is of a magnetic conductive structure and is arranged on the piston cylinder in a sleeving manner. The device is compact and reasonable in structure and convenient to operate, high-pressure gas serves as a power source, the inner magnetic ring set is driven to do work, the outer magnetic ring set is driven to move in the same direction, and the purpose of releasing loads is achieved by means of the magnetic force transmission principle; the speed, overload and noise in the load release process can be effectively controlled. According to the side-pull type underwater load release device for the single-stage piston cylinder, a two-time air inlet mode is adopted, energy distribution in the release process can be greatly slowed down, and release overload and flow noise are remarkably reduced.

    本发明涉及磁动力制动结构及负载释放装置,包括活塞筒;气压释放结构;磁力传动装置,其经高压气体带动并沿着活塞筒侧壁移动,其结构包括具有磁性的外磁环组和内磁环组;制动导体环,其为导磁结构并套设在活塞筒上。本发明结构紧凑、合理,操作方便,通过采用高压气体作为动力源,驱动内磁环组做功,并带动外磁环组同向运动,利用磁力传递原理达到释放负载的目的,同时通过设计释放装置排气参数、内外磁环参数和制动导体环参数等参数,可以对负载释放过程速度、过载及噪声进行有效地控制。本发明设计的侧拉式单级活塞缸水下负载释放装置,采用两次进气方式,可以大幅平缓释放过程的能量分布,显著降低释放过载和流动噪声。
