Abstract

The invention discloses a weak ocean current power system for energy supplement for a deep sea subsurface buoy. The weak ocean current power system comprises an impeller structure and a power generation structure, wherein the impeller structure comprises a central shaft, a first flow guide cover, a second flow guide cover and an impeller hub; the first flow guide cover and the second flow guide cover are fixed to the central shaft; the impeller hub is positioned between the first flow guide cover and the second flow guide cover and is rotatably fixed to the central shaft and rotates around thecentral shaft; a plurality of blades are arranged on the impeller hub; the impeller hub faces one side of the first flow guide cover and is provided with a ratchet wheel; the power generation structure comprises at least one pendulum hammer and at least one coil; the coil is fixed to the inner side of the first flow guide cover; the pendulum hammer is rotatably fixed to the central shaft and rotates around the central shaft; the pendulum hammer comprises a swing arm and a hammer head; the hammer head is provided with magnetic poles; and the swing arm is provided with pawls. The weak ocean current power system is suitable for the environment with low flow velocity in a deep sea, provides low-power energy supplement application for observation equipment, detection equipment or communicationequipment, and has the characteristics of self-starting, high reliability and high absorption and conversion efficiency.

Description

technical field [0001] The invention relates to the fields of deep sea detection submersible buoy and ocean current power generation, in particular to a weak ocean current power generation system used for energy supplementation of deep sea submersible buoy. Background technique [0002] Deep-sea observation submersible buoy is a common equipment for observing the marine environment, and plays a vital role in the detection, development, utilization and protection of the ocean. The cost of deploying and recovering deep-sea diving marks is high, and energy is one of the key factors limiting its long-term deployment. Ocean current power generation is similar to wind power generation, which is a device that generates electricity by collecting ocean current energy. The deep sea current is weak, and has high sea salinity and water pressure, so the working environment is harsh. The use of ocean current power generation in the energy supply of deep-sea submersibles is a field worth...
