Description

Fluid energy harvesting conversion device and energy transfer output device and power generation

Technical field

The invention belongs to the technical field of energy conversion, and particularly relates to a fluid energy collecting and converting device capable of converting fluid kinetic energy in any direction into a directional rotation about a rotating shaft, and a device for transmitting energy of the fluid energy collecting and converting device, and finally using The energy of the fluid energy harvesting conversion device drives the generator to generate electricity.

Background technique

At present, people mainly use solar energy, atomic energy, water energy and wind energy to obtain energy. There are certain pollutions and hazards in atomic energy. Solar energy is greatly affected by time and region. Because of the influence of water flow direction and flow velocity, water energy usually needs to be built large. The dam is used to increase the energy density. After the dam or reservoir is high, the water is applied to the turbine through the pipeline to drive the engine to generate electricity. The project is complicated, the investment is large, the construction period is long, the cost is high, and the turbine is extremely demanding. The use of wind energy is usually based on the construction of a large number of towers and large-area blades in areas with high wind speeds to obtain energy, which is greatly affected by the area. The existing vertical and horizontal wind generators are less efficient. It can be seen that when the water flow speed is low or the wind speed is small, the power generation efficiency is affected, and more importantly, when the water flow or the wind continuously changes direction, it becomes difficult to obtain electric energy.

Obviously there are still many huge ocean currents in the ocean. These ocean currents are driven by wind and other powers along a certain route. At present, mainly by installing turbines and generators in the ocean currents, the turbines are driven by the ocean currents, and then the turbines are used to drive the generators. The difficulty lies in the installation and fixing of the turbines and generators. It is usually necessary to install the columns after piling on the seabed. It is difficult to install the turbine and generator on the column. There are also turbines and generators installed on the floating platform of the water. When in use, the floating platform on the water is towed to the ocean current center, and the turbine is driven by the ocean current to generate electricity. However, under normal conditions, the current flow rate is below 1 m/s, and the power density is higher. Small, in order to increase the amount of power generation, it is necessary to make the blades of the turbine large or through the collecting bucket to increase the flow rate of the ocean current. Even if the blade is increased to increase the force or the collecting bucket is used to increase the flow rate of the ocean current, the energy conversion efficiency is not high and needs further improvement.
