Description

Mobile offshore wind turbine

The present invention relates to an offshore wind turbine, and more particularly to a mobile offshore wind turbine that can be moved to enhance power generation efficiency as the wind direction changes.

Offshore wind power refers to the construction of windfarms in water bodies to generate electricity from wind power. As the location of finding suitable wind farms on land is becoming more and more difficult, in many cases, mainly due to the noise generated by wind turbines and the aesthetic effect of installing wind turbines, the public has generated a lot of objections to the placement of wind turbines, and in order to make wind Turbines work effectively, requiring, for example, large areas without trees and buildings, and such areas are not always readily available.

It has become more and more common to place wind turbines or wind parks close to the coast (offshore) or at sea recently, and the wind can be more constant compared to the larger area of the offshore turbine on land. The wind speed is higher and the wind shear is usually reduced, and as the noise constraints are reduced, the wind turbine can rotate at a higher speed.

In addition, offshore wind power can help reduce energy imports, reduce air pollution and greenhouse gases, meet renewable electricity standards, and create jobs and business opportunities. In addition, the wind is stronger outside the coast, unlike the wind on the mainland, the wind in the sea can be strong in the afternoon, which matches the time people use the most electricity. Offshore turbines can also be placed along the coast near the power-hung population, eliminating the need for new land-based transmission lines.

However, due to its size, offshore wind power is considered to be the most expensive power generation technology. For example, for non-floating offshore wind turbines, offshore maintenance and repair costs are high due to travel, distance, downtime, and the removal of such abutments after the wind farm is shut down. Moreover, non-floating offshore wind turbines may be susceptible to severe weather conditions and poor installation accessibility. In addition, the offshore wind farm of the fixed abutment is commercially Used only to reach a water depth of about 30 meters, which can only account for a small fraction of the global available offshore wind energy.

Conventional wind turbines have been developed and used in deep water farther from the coast. A floating wind turbine platform, as shown in Figure 6, includes at least three columns and an active ballast system, the active ballast system will be water ballasted, as disclosed in U.S. Patent No. 8,471,396 to Rodd. Move between the columns to keep the tower upright. However, even with the floating wind turbine disclosed in U.S. Patent No. 8,471,396, its mobility is very limited. In addition, the cost of manufacturing a floating wind turbine is still high. Moreover, floating wind turbines are still susceptible to severe weather conditions.

Further, as shown in FIG. 7, an offshore wind turbine abutment is disclosed in US Patent No. 2013/0266453 to Moiret, which comprises: a platform carrying a support for a wind turbine tower in its central region. a plurality of leg guides in a peripheral region of the platform; a plurality of legs movable between a lifting position for transport and a lowered position for parking on the seabed as disclosed in U.S. Patent No. 8,471,396 Like wind turbines, Morritt's open wind turbines also have limited mobility, which can be susceptible to severe weather. Therefore, there remains a need for new and improved wind turbines that overcome the above problems.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a mobile offshore wind turbine for the above-mentioned shortcomings existing in the prior art.

A base has a central member and two side members, the side members are arranged on both sides of the central member, a cylinder is disposed at the central member of the base, and the plurality of turbine blades each have a blade surface, plural Each of the connecting rods is radially extended from the cylinder and connected to the turbine blades, and the turbine blades are rotatably disposed on the corresponding connecting rods, and the turbine blades are vertically aligned with the cylinder.

Wherein, the turbine blade is provided with a controller for detecting the wind direction by the controller and further controlling the moving direction of the wind turbine.

Where the surface of the blade of the turbine blade is substantially parallel to the wind direction, the wind The turbine can move in the wind direction.

Wherein, the controller sends the detection result to the control center, thereby combining the detection result and the weather condition to generate an optimized route for the wind turbine.

Wherein, when the blade surface of the turbine blade is substantially non-parallel to the wind direction, the turbine blade is driven by the wind to further drive the cylinder to generate electricity.

Wherein the controller on the turbine blade changes the direction of the blade surface to correspond to the wind direction, enabling the turbine blade to rotate continuously to drive the cylinder.

Among them, the turbine blades are controlled by the controller to maximize the amount of power generated.

A first primary object of the present invention is that when the wind direction is substantially parallel to the blade surface of the turbine blade, the wind turbine can be moved offshore, thereby actually driving the wind turbine to move along the wind direction.

A second main object of the present invention is that the controller is disposed on each of the turbine blades to control the direction of the blade surface such that the turbine blades can be continuously rotated to drive the cylinders to maximize the amount of power generated.

A third primary object of the present invention is to move the wind turbine to a safer position through the controller when weather conditions change to avoid damage due to inclement weather.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.
