Benefits of technology

[0019]The primary purpose of the present invention is to provide a hooded marine float wind power generator,

Problems solved by technology

(1) Blades and generator must be fixed on the ground by a lower, but (they must also be direction changeable with the direction of wind flow in order to exactly lace the wind flow: Titus, they cannot be completely fixed with, respect to the tower and is often mounted to the tower with bearing. This makes the construction of the tower very difficult and expensive.
(2) The tower has to bear the from wind and side winds, as well as lilting force induced by the blades when blades are acted upon by the winds and the weight of the power generator. Thus, when the wind is of a great speed, the tower may tail to bear the wind force. Consequently the wind power generation system has to be shut down when wind speed exceeds 25 m/sec.
(3) The centrifugal force acting on foe windmill blade is large for large-sized wind power generation system and thus, the wind power generation system must has a strong mechanical structure, which is often associated with high expense.
(4) Additional loads, such as lead/lag of the rotation of the windmill blades, flapping, pitching and wind shearing, wind gusts, wind shifts, gravity and tower shadow; may cause periodic shock and resonance, which influences the service lives of the blades, bearing, aid tower.
(5) The reunion of the windmill blades causes great noise, which makes residence very tough.
(6) Birds may be damaged and killed.
(7) Radio communication may be interfered with.
(8) A large area is occupied, leading to high costs of land acquirement Marine wind power generation may solve the problem associated with land acquirement and possesses an advantage mat the air how or wind is more stable in the sea than in the land. However, construction of windmill tower on sea is

Embodiment Construction

[0036]The following descriptions are of exemplary embodiments only and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient Illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of rise elements described without departing from the scope of the invention as set forth in the appended claims.

[0037]With reference to the drawings, and in particular to FIGS. 1-4, a hooded marine float, wind power generator construction in accordance with tire present invention comprises a float platform 1 on which a support frame 21 is mounted for supporting thereon a generator 2 and a hood 3 serving as a diffuser. The generator 2 is provided with, a windmill, blade set 22 and is electrically connected to a power transmission, line (as well as a power gate control line and a signal line) 23. The float plat

Abstract

A hooded marine float wind power generation system includes a float platform set on a sea surface, a steel cable connecting the float platform and fixed to a sea bottom anchor to prevent undesired shining of the float platform. The float platform is provided with a wind power generator that is completely fixed on the float platform. A hood surrounds the generator to also function as a tail wing so as to make the float platform and the generator to change direction in response to wind direction and thus directly opposing to the wind to extract the most wind power and realize the best power generation performance. Due to the floating configuration of the float platform, the hood will not be tipped or damaged by side winds. Windmill blades can be made small is size and costs are thus reduced.
