Abstract

The utility model provides an umbrella-shaped wind driven generator, which comprises a main column, a sliding sleeve, a main motor, a plurality of connecting rods, a plurality of stay bars, an impeller, a secondary motor and a wind scooper, wherein amount of the connecting rods is equal to that of the stay bars. The main column is sleeved with the sliding sleeve, the main motor is mounted at the top of the main column, a control system is installed at the bottom of the main column, the lower portion of the main column is supported by the ground through a plurality of seat rods, one end of each connecting rod is hinged onto the main column, the connecting rods are uniformly distributed on a periphery adopting the main column as a circle center, one end of each stay bar is hinged onto the sliding sleeve while the other end of each stay bar is hinged to the middle of each connecting rod, the impeller and the secondary motor are mounted at the tail end of the main column, and the wind scooper is covered outside the impeller. The umbrella-shaped wind driven generator is low in attitude, has large windward area, and can realize general power generation when in breeze.

Description

The umbrella shape wind-driven generator

Technical field

The utility model relates to the wind-driven generator field, is specifically related to a kind of umbrella shape wind-driven generator.

Background technique

Natural wind-force is a kind of inexhaustible, nexhaustible energy, and utilizing wind-power electricity generation is one-time investment, long-term good approach of being benefited.Therefore people constantly take the whole bag of tricks, have developed the various machinery equipments that are used for wind-power electricity generation.

Existing wind-driven generator, its blowing area is less, and generating capacity is poor when wind speed is low; Blade then may suffer damage when high wind.The blade rated wind velocity requires high, manufacturing, transportation, installation cost height.Wind wheel is vertical and is installed on the tower seat, and the tower seat needs very high, generally reaches tens meters even higher, and must be very firm, and investment cost is big, installation and maintenance inconvenience.The wind-force that acts on the wind wheel partly plays counter productive, so utilization ratio is on the low side.

The content of model utility

Low at existing wind-driven generator to Wind Power Utilization efficient, the pylon height, flimsy problem, the claimant improves through research, and a kind of umbrella shape wind-driven generator is provided, and highly low, blowing area is big, gets final product normal power generation under the gentle breeze state.

The technical solution of the utility model is as follows:

A kind of umbrella shape wind-driven generator comprises principal post, sliding sleeve, main motor, a plurality of connecting rods, a plurality of struts, impeller, sub-motor and the wind scooper that equate with connecting rod quantity;

Be arranged with sliding sleeve on the described principal post, at the principal post top main motor be installed, the bottom of principal post is equipped with control system, and the bottom of principal post is by a plurality of bars and ground supports;

One end of described each connecting rod is hinged on the principal post, and each connecting rod evenly distributes on the circumference that with the principal post is the center of circle; Strut one end is hinged on the sliding sleeve, and the strut the other end is hinged on the middle part of connecting rod;

The end of described connecting rod is equipped with impeller and sub-motor, and the outside of described impeller is covered with wind scooper.

Its further technological scheme is: described each impeller be same towards.

And its further technological scheme is: the quantity of described connecting rod is the even number more than four or four.

And its further technological scheme is: the top of described main motor is equipped with lightning conductor.

Useful technique effect of the present utility model is:

(1) ability of the utility model seizure wind energy is strong.Existing blower fan tower seat highly generally reaches tens meters even higher, and only four, five meters of the utility model height because blowing area is big, get final product normal power generation under the gentle breeze state of low latitude.By arranging a plurality of wind wheels, the diameter of each wind wheel is reduced, the load that pylon is born reduces, and it is highly reduced.

(1) the utility model wind wheel is Height Adjustable.Umbrella shape can be strutted fully in that low wind speed state is following, improve height and generate electricity with wind-engaging; And surpass under the state of 20～25m/s at wind speed, umbrella shape can be taken down, reduce height to realize self-protection.Generating capacity when so promptly having increased weak wind, the wind wheel blade in the time of can avoiding high wind again damages.The rated wind velocity of wind wheel blade requires to reduce simultaneously, and cost is reduced.

When (three) sub-motor of the present utility model was worked, main motor was also worked under the rotation of umbrella shape drives, and by the cooperating of a plurality of motors, utilization ratio of wind energy was improved.

(4) the utility model is easy to maintenance, need not large-scale crane and cooperates, and cost reduces greatly, can control thereby realization is any by the optional watt level of control system.

Embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described by embodiment.

As shown in Figure 1, the utility model is by principal post 1, sliding sleeve 2, and main motor 3, a plurality of connecting rods 4, a plurality of struts 5 that equate with connecting rod 4 quantity, impeller 6, sub-motor 7 and wind scooper 8 are formed.Be arranged with sliding sleeve 2 on the principal post 1, sliding sleeve 2 can be in the limited slip of principal post 1 Vertical direction.At principal post 1 top main motor 3 is installed, the bottom of principal post 1 is equipped with control system 9, and control system 9 is electrically connected so that it is controlled with each motor.The bottom of principal post 1 is by a plurality of bars 10 and ground supports.The top of main motor 5 is equipped with lightning conductor 11.

As shown in Figure 2, an end of each connecting rod 4 is hinged on the principal post 1, and each connecting rod 4 evenly distributes on the circumference that with principal post 1 is the center of circle.The quantity of connecting rod 4 is the even number more than four or four, is preferably 6 in the present embodiment.See Fig. 1, strut 5 one ends are hinged on the sliding sleeve 2, and strut 5 the other ends are hinged on the middle part of connecting rod 4.

See Fig. 2, the end of each connecting rod 4 is equipped with interconnective impeller 6 and sub-motor 7, and the outside of impeller 6 is covered with wind scooper 8.Each impeller 6 be same towards.Each connecting rod 4 is that the center turns clockwise with principal post 1 during work.

Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
