The invention relates to an underwater electric winch sealing device, and belongs to the technical field of underwater winding and unwinding equipment. The underwater electric winch sealing device comprises a dynamic sealing device, the dynamic sealing device comprises an outer ring and an inner ring, the inner ring is arranged on the inner side of the outer ring, and a sliding frame and two end covers are connected between the outer ring and the inner ring in a sliding mode; according to the underwater electric winch sealing device, the self-adaptive pressure adjusting device can actively adjust the pressure of the hydraulic oil between the outer ring and the inner ring so as to meet the requirement that the dynamic sealing device can normally operate at the corresponding water depth, meanwhile, in the submerging process of the underwater electric winch, water pressure can also act on the hydraulic oil, and when the water pressure is larger than the pressure of the hydraulic oil, the dynamic sealing device can normally operate. At the moment, the hydraulic pressure of the hydraulic oil can be kept consistent with the external water pressure, and the probability that the hydraulic oil and water are blended due to the fact that the pressure difference between the hydraulic pressure of the hydraulic oil and the nearby water pressure is too large is effectively reduced.
本发明涉及一种水下电动绞车密封装置,属于水下收放设备技术领域。该水下电动绞车密封装置,包括动密封装置,所述动密封装置包括外圈和内圈,所述内圈设置于外圈的内侧,所述外圈与内圈之间滑动连接有滑动架和数量为两个的端盖;上述水下电动绞车密封装置,自适应调压装置不仅能够主动调节外圈与内圈之间液压油的压力,以满足动密封装置在对应水深处能够正常运行,同时在水下电动绞车下潜的过程中,水压也能够作用在液压油上,当水压大于液压油的压力时,水压就能够间接挤压液压油,此时液压油的液压力就能够与外界水压保持一致,有效的降低了因液压油的液压力与附近水压压差过大而导致液压油与水交融的概率。
