The invention relates to underwater mooring equipment, in particular to an underwater tension-bearing electric swivel, which includes an outer sealing shell, an inner rotating load-bearing transmission device, and a cable protection and sealing device. The outer sealing shell includes a bottom bracket, a lubrication resistant Grinding plate, skeleton oil seal, cylinder body, upper cover, sealing ring and connecting bolts; internal rotating load-bearing transmission device including bottom support center shaft, gasket, limit collar, thrust ball bearing, split nut and slip ring; cable The protection and sealing device includes cable protection screws, compression hollow bolts and sealing rubber pads; the filling liquid is filled in the outer sealing shell, and the internal rotating load-bearing transmission device is located in the filling liquid. The invention is connected to the cable, which can remove the torsional load while ensuring the transmission of the up and down signals; the cylinder is filled with oil, and the water does not infiltrate, which not only ensures the sufficient lubrication of the internal rotating load-bearing transmission device, but also makes the invention suitable for underwater use. The pressure difference between inside and outside is almost zero, which avoids deformation under external pressure.
Description
technical field [0001] The invention relates to underwater mooring equipment, in particular to an underwater tension electric swivel. Background technique [0002] The ocean is rich in resources. Marine biological resources, seawater chemical resources, marine mineral resources, marine energy, and maritime shipping and transportation all have a major impact on the survival and development of human beings and the revitalization and progress of world civilization. In addition to rich marine resources, the vast sea area is also a channel of communication and a natural barrier to defend against the invasion of foreign enemies. The development and utilization of the ocean and the development of the marine industry are closely related to the development of human civilization. The fixed-point ocean observation system is an important equipment for ocean development and ocean observation research. It generally consists of a mooring system composed of bottom anchors, anchor cables and...
