The invention relates to the technical field of marine scientific investigation equipment, in particular to a winch emergency lowering and pressure compensation system which comprises a reversing valve, a winch assembly, a brake assembly and an emergency function assembly. The brake part is controlled by a brake assembly to brake the power motor, and two cavities of the power motor are communicated with the reversing valve to form a working loop. The emergency function assembly comprises an energy accumulator, a first stop valve, a hydraulic control valve and a speed regulating valve, the first stop valve, the hydraulic control valve and the speed regulating valve are sequentially communicated, the first stop valve and the speed regulating valve are correspondingly communicated with two cavities of the power motor to form an emergency lowering loop, and the energy accumulator is communicated with one cavity of the power motor through an energy storage oil way. The energy accumulator is further communicated with the two cavities of the power motor through a compensation oil way, the working loop and the compensation oil way are each provided with a control oil way for providing a control oil source for the brake assembly, and a second stop valve is arranged on the control oil way of the compensation oil way.

    本发明涉及海洋科考装备技术领域,尤其涉及一种绞车应急下放和压力补偿系统,其包括换向阀、绞车组件、刹车组件和应急功能组件,绞车组件包括动力马达、卷筒和刹车件,卷筒与动力马达的输出端连接,刹车件由刹车组件控制对动力马达刹车,动力马达的两个腔分别连通换向阀形成工作回路;应急功能组件包括蓄能器及依次连通的第一截止阀、液控阀和调速阀,且第一截止阀和调速阀对应与动力马达的两个腔连通形成应急下放回路,蓄能器通过储能油路与动力马达的一个腔连通,蓄能器还通过补偿油路分别与动力马达的两个腔连通,工作回路和补偿油路上均设置有为刹车组件提供控制油源的控制油路,且补偿油路的控制油路上设置有第二截止阀。
