Abstract
An apparatus for generating electric power from wind energy includes: a blade unit having upright blades connected fixedly to an upright rod that has a lower end disposed pivotally in a base such that the blade unit is rotatable relative to the base so as to convert wind energy into a mechanical rotary power output; a generator disposed in the base and coupled to the lower end of the upright rod to convert the mechanical rotary power output into electric power; and a wind-collecting cover mounted pivotally on the base for covering the blade unit, rotatable relative to the base and formed with opposite wind inlet and outlet. The wind-collecting cover rotates in response to blowing of wind thereto so that the wind flows into an inner space in the cover via the wind inlet and out of the inner space in the cover via the wind outlet.
Claims (6)
1. An apparatus for generating electric power from wind energy, comprising:
a base;
a blade unit including an upright rod extending vertically along a pivot axis and having a lower end disposed pivotally in said base, and an upper end, and a plurality of upright blades connected fixedly to the upright rod such that said blade unit is rotatable relative to said base about the pivot axis so as to convert wind energy into a mechanical rotary power output;
a generator disposed in said base and coupled to said lower end of said upright rod of said blade unit to convert the mechanical rotary power output into electric power;
and a wind-collecting cover mounted pivotally on said base for covering said blade unit such that said wind-collecting cover is rotatable relative to said base about the pivot axis, said wind-collecting cover being configured with an inner space, and having a first end portion formed with a wind inlet in spatial communication with said inner space, and a second end portion opposite to said first end portion in a direction perpendicular to the pivot axis and formed with a wind outlet in spatial communication with said inner space and having a size smaller than that of said wind inlet in said first end portion;
wherein said wind-collecting cover rotates in response to blowing of wind thereto so that the wind flows into said inner space in said wind-collecting cover via said wind inlet to drive rotation of said blade unit and out of said inner space in said wind-collecting cover via said wind outlet.
a base;
a blade unit including an upright rod extending vertically along a pivot axis and having a lower end disposed pivotally in said base, and an upper end, and a plurality of upright blades connected fixedly to the upright rod such that said blade unit is rotatable relative to said base about the pivot axis so as to convert wind energy into a mechanical rotary power output;
a generator disposed in said base and coupled to said lower end of said upright rod of said blade unit to convert the mechanical rotary power output into electric power;
and a wind-collecting cover mounted pivotally on said base for covering said blade unit such that said wind-collecting cover is rotatable relative to said base about the pivot axis, said wind-collecting cover being configured with an inner space, and having a first end portion formed with a wind inlet in spatial communication with said inner space, and a second end portion opposite to said first end portion in a direction perpendicular to the pivot axis and formed with a wind outlet in spatial communication with said inner space and having a size smaller than that of said wind inlet in said first end portion;
wherein said wind-collecting cover rotates in response to blowing of wind thereto so that the wind flows into said inner space in said wind-collecting cover via said wind inlet to drive rotation of said blade unit and out of said inner space in said wind-collecting cover via said wind outlet.
2. The apparatus as claimed in Claim 1, wherein said wind-collecting cover further has an intermediate portion interconnecting said first and second end portions, and a width that decreases gradually from said intermediate portion toward said first and second end portions.
3. The apparatus as claimed in Claim 1, wherein said base includes a base body, and a mounting tube extending upwardly from a top side of said base body for permitting extension of said lower end of said upright rod of said blade unit into said base through said mounting tube, and a first bearing disposed between an outer annular surface of said lower end of said upright rod of said blade unit and an inner annular surface of said mounting tube of said base.
4. The apparatus as claimed in Claim 3, wherein said wind-collecting cover has a bottom wall, a top wall, and a C-shaped surrounding wall extending vertically between peripheries of said bottom and top walls and cooperating with said bottom and top walls to define said inner space thereamong, said bottom wall of said wind-collecting cover being formed with a through hole for permitting extension of said lower end of said upright rod of said blade unit therethrough, said surrounding wall of said wind-collecting cover having opposite ends defining said wind inlet therebetween, and being formed with said wind outlet, said top wall having a bottom surf ace formed with a positioning groove for permitting extension of said upper end of said upright rod of said blade unit thereinto.
5. The apparatus as claimed in Claim 4, wherein:
said through hole in said bottom wall of said wind-collecting cover is defined by an inner annular surface of said bottom wall;
said positioning groove in said top wall of said wind-collecting cover is defined by an inner annular surface of said top wall; and said wind-collecting cover includes a second bearing disposed between said inner annular surface of said bottom wall and an outer annular surface of said mounting tube of said base, and a third bearing disposed between said inner annular surface of said top wall and an outer annular surface of said upper end of said upright rod of said blade unit.
said through hole in said bottom wall of said wind-collecting cover is defined by an inner annular surface of said bottom wall;
said positioning groove in said top wall of said wind-collecting cover is defined by an inner annular surface of said top wall; and said wind-collecting cover includes a second bearing disposed between said inner annular surface of said bottom wall and an outer annular surface of said mounting tube of said base, and a third bearing disposed between said inner annular surface of said top wall and an outer annular surface of said upper end of said upright rod of said blade unit.
6. The apparatus as claimed in Claim 4, wherein said wind-collecting cover further has two wind-guiding plates connected fixedly and respectively to said ends of said surrounding wall and extending into said inner space such that an inwardly converging wind-guiding channel is defined between said wind-guiding plates.
