Problems solved by technology
[0004] However, the flow velocity in the deep sea is low, and its flow velocity is between 0.1m / s-0.5m / s. The ocean current turbines used in this type of power station need to solve the problem of low-speed start-up
According to industry reports, there is no way to solve such a problem well with lift-type horizontal-axis current turbines.

The invention discloses an ocean power supply station based on a contra-rotating helical blade ocean current turbine and application. The ocean power supply station comprises an energy storage power supply module, a power generation module, contra-rotating helical blades and extension arms. The energy storage power supply module is connected with the extension arm, a plurality of supporting arms extend out of the extension arm, each supporting arm is provided with a power generation module, and each power generation module is provided with a contra-rotating spiral blade. The multiple sets of contra-rotating spiral blades are arranged to adapt to low-speed starting, the contra-rotating spiral blades are opposite in rotating direction, the hydrodynamic efficiency can be directly improved, the opposite rotating direction can be provided for the power generation module, and therefore the higher magnetic induction line cutting linear speed is formed, and the higher motor conversion efficiency is achieved.
Description
technical field [0001] The invention belongs to the technical field of ocean current turbines, in particular to an ocean power supply station and its application based on counter-rotating spiral blade ocean current turbines. Background technique [0002] With the continuous increase of human demand for ocean exploration, a deep-sea observation network composed of deep-sea sonar unmanned submersibles has emerged. The current deep-sea observation network is mainly based on land-based power supply and ship-based power supply. The base power supply faces high laying and maintenance costs, and the ship-based power supply also faces high maintenance costs. In the underwater attack and defense system, the deep-sea monitoring network, which is mainly based on land-based power supply, also faces the risk of system paralysis after the main power grid is damaged. [0003] The underwater power supply station using deep sea current energy can solve this problem well, so this kind of cha...
