Subsea base platform with ocean current power generation

Abstract

The invention discloses a seabed base platform capable of power generation by ocean currents, comprising a platform main body, a gravity ballast assembly connected to the bottom of the platform main body through a steel cable, the downward pull force generated by the gravity of the gravity ballast assembly and the platform main body itself The buoyancy is balanced; the main body of the platform includes a connecting bridge assembly with a ballast compartment, a power generation assembly, and a yaw wing; the gravity ballast assembly includes a gravity block and a steering assembly fixed on the gravity block to realize the horizontal steering of the platform main body. It includes a lower thrust bearing, a sliding table that can freely rotate around the axial direction, an upper thrust bearing and a fixed ring, wherein the fixed ring is fixedly connected with the gravity block and presses the steering assembly. One end of the steel cable is fixed to the main body of the platform, and the other end is connected to the sliding table. It can be fixed and rotate with the sliding table. The invention uses the steering assembly to realize the horizontal steering of the platform main body, so that the seabed base platform is consistent with the incoming flow direction, thereby further realizing higher efficiency power generation.

Description

technical field [0001] The present invention relates, in particular, to a seabed base platform capable of generating electricity from ocean currents. Background technique [0002] With the rapid development of marine scientific research, marine disaster prevention and emergency, and marine economy, marine environmental observation and survey technology has also experienced from the first observation platform (roadbed, sea-based), the second observation platform (space) to the third History of Observation Platform (Seabed). The observation method has experienced a leap from low-frequency, instantaneous, and static observation to long-term, continuous, and dynamic observation. [0003] As a ground-based ocean monitoring device, the seabed base has the technical advantages of all-weather, multi-period, uninterrupted, multi-parameter, and high-quality compared with traditional observation technology. As the main observation structure of the submarine observation platform, the ...

Problems solved by technology

Due to the limitation of its own battery capacity, the non-cable subsea platform cannot be continuously observed for a long time. Although the cable subsea platform can achieve continuous observation, the cost of laying submarine cables is high, and the requirements for laying environmental conditions are relatively high.
