Problems solved by technology

First of all, due to the use of mechanical transmission, such a structure has a greater impact on the mechanical structure of the system. On the other hand, the increase in underwater components also increases the failure rate of the device, and underwater maintenance operations are more difficult.
Secondly, for large units, its heat dissipation is also a problem

It includes the following several portions: blade wheel, speed-increasing box, hydraulic pump, valve control mechanism, hydraulic motor, power generator, commutation storage excitation transformation controller, power generation platform and tower frame. Besides, said invention also provides the working principle of said hydraulic type underwater windmill power generation equipment and its concrete operation method.

Description

technical field [0001] The invention relates to hydroelectric power generation equipment, in particular to a hydraulic underwater windmill power generation device. Background technique [0002] "Underwater windmill" is a new type of marine energy development and utilization device that entered the research field in the early 21st century. It uses the principle of wind turbine power generation, adopts the Bezier energy capture theory, captures the kinetic energy of the water flow through the impeller and converts it into electrical energy. Since it uses the flow energy of the ocean current, it is a renewable follow-up energy source. At present, the underwater windmills designed in the United Kingdom and the United States are all single-impeller mechanisms. The impeller rotates under the action of water flow, and the generator is driven by the mechanical transmission speed-up box to output electric energy, and the impeller, speed-up box, generator, etc. Get in the cabin. Fi...
