Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of wind-driven generator of the present utility model, comprise cabin 1, pylon 2 and wind wheel 3, wind wheel 3 is connected to the side in cabin 1, the bottom in cabin 1 is movably connected in pylon 2 top, it is characterized in that, also comprises Equipotential connection device 4, the bottom of Equipotential connection device 4 is fixedly connected on pylon 2, and the top of Equipotential connection device 4 is connected on the inwall in cabin 1.
In the utility model, cabin 1, pylon 2 and wind wheel 3 are prior art.Pylon 2 is fixedly connected with on the ground.Cabin 1 and pylon 2 are metal and make.The bottom in cabin 1 is connected on pylon 2 by revolution wheel disc.Cabin 1 can rotate around the axis of pylon 2.The utility model has installed Equipotential connection device 4 on the wind-driven generator of existing structure.The bottom of Equipotential connection device 4 is fixedly connected on pylon 2, and the top of Equipotential connection device 4 is connected on the inwall in cabin 1.When cabin 1 rotates, the top of Equipotential connection device 4 also rotates thereupon, but the bottom of Equipotential connection device 4 maintains static all the time.The excess charge that cabin 1 exists is dredged in pylon 2 by Equipotential connection device 4, then imports ground into.Utilize the excess charge that Equipotential connection device 4 pairs of cabins 1 exist effectively to dredge, avoid it to damage.
As a kind of embodiment, as shown in Figures 2 to 5, Equipotential connection device 4 comprises one end and is set to the coil cabin body 401 of openend, hatchcover 402, coil strap 403 and inner core 404, and hatchcover 402 is positioned at the openend of coil cabin body 401, and hatchcover 402 and coil cabin body 401 form coil cabin; Coil strap 403 and inner core 404 are arranged in coil cabin, inner core 404 is fixedly connected on the wall in coil cabin, coil strap 403 is around inner core 404 rotary setting, and one end of coil strap 403 is fixedly connected with coil cabin body 401, and the other end of coil strap 403 is fixedly connected with hatchcover 402.Coil cabin body 401 is fixedly connected on the inwall of pylon 2, and hatchcover 402 is fixedly connected on the inwall in cabin 1, and hatchcover 402 and cabin 1 coaxial rotating.Coil cabin body 401 can be fixedly connected on the inwall of pylon 2 by the first electric-conductor, and hatchcover 402 can be fixedly connected on the inwall in cabin 1 by the second electric-conductor.
The Equipotential connection device 4 of said structure, the electric current that can realize on rotating parts transmits to static component.Rotating parts is in the parts of rotation status when referring to work.Static component refers to the parts remained static.The parts of rotation status are effectively connected with static parts by Equipotential connection device 4, thus realize the transmission of electric current.Specifically, be fixed on rotating parts by hatchcover 402, rotating parts drives hatchcover 402 to rotate, and coil cabin body 401 is fixedly connected with pylon 2, and body 401 position, coil cabin does not change.Like this, the excess charge that cabin 1 exists, flows to pylon 2 by coil strap 403.Hatchcover 402 rotates, and drives coil strap 403 to rotate, coil strap 403 is drawn in around inner core 404.Preferred as one, coil strap 403 has certain tension force, and it under the drive of the coil cabin body 401 rotated or hatchcover 402, can draw in around inner core 404.When external force is eliminated, coil strap 403 can return to home position automatically.Like this, coil strap 403 not easily self is wound around.
The setting of coil cabin body 401 and hatchcover 402, can determine according to actual conditions.When installing Equipotential connection device 4 of the present utility model, when having parts can serve as coil cabin body 401 or hatchcover 402 in rotating parts, device so of the present utility model can save coil cabin body 401 or hatchcover 402.If when having parts can serve as coil cabin body 401 or hatchcover 402 in static component, device so of the present utility model can save coil cabin body 401 or hatchcover 402 equally.In device of the present utility model, the number of turns that coil strap 403 rotates is decided by the length of coil strap 403.
As a kind of embodiment, described inner core 404 is fixedly connected on hatchcover 402.Be arranged on by inner core 404 on hatchcover 402, on the one hand convenient manufacture, hatchcover 402 is more stable in rotary course on the other hand.
As a kind of embodiment, connected by coil strap 403 between coil cabin body 401 and hatchcover 402, between coil cabin body 401 and hatchcover 402, do not have direct annexation.Hatchcover 402 and coil cabin body 401 should keep suitable position, and when making coil strap 403 shrink or open distortion, the friction not by hatchcover 402 and coil cabin body 401 is disturbed.In order to reach this object, the openend of described coil cabin body 401 is provided with boss, and hatchcover 402 is positioned on boss.Like this, when the pulling force that hatchcover 402 is subject to coil strap 403 moves in coil cabin body 401, be subject to the spacing of boss, can not produce the winding of coil strap 403 and interfere.
As a kind of embodiment, the inner of coil strap 403 is connected with hatchcover 402, and the outer end of coil strap 403 is connected with coil cabin body 401; Or the inner of coil strap 403 is connected with coil cabin body 401, the outer end of coil strap 403 is connected with hatchcover 402.The two ends of coil strap 403 connect hatchcover 402 and coil cabin body 401, and concrete connected mode is determined according to actual demand.
As a kind of embodiment, have gap between the innermost circle of described coil strap 403 and inner core 404, the outmost turns of coil strap 403 is covered on the inwall of coil cabin body 401.Being wound around to coil strap 403 to improve space, have gap between the innermost circle of described coil strap 403 and inner core 404, otherwise the rotating parts in the external world cannot rotating.
The structure of coil strap 403 or material can be selected according to actual conditions.Coil strap 403 is preferably made of metal, and coil strap 403 has conductivity.Such as: iron, copper etc.Preferably copper material.This is because the electric conductivity of copper is good.In the course of work of this connection transfer device, electric current is not realize flowing between hatchcover 402 and coil cabin body 401, but in hatchcover 402, flowing between coil strap 403 and coil cabin body 401.Relatively rotate between hatchcover 402 and coil cabin body 401, may come in contact bad.And the utility model center line astragal 403 two ends are connected with hatchcover 402 and coil cabin body 401 respectively.Like this, electric current is equivalent to flow in a wire, can not come in contact bad, affect the situation that electric current is dredged.
The electric charge that cabin 1 exists, is transferred in coil strap 403 by hatchcover 402, then is transferred on pylon 2 by coil cabin body 401, thus completes dredging of electric charge on cabin 2.Hatchcover 402 can be followed cabin 1 and be rotated.The rotation of hatchcover 402 can drive coil strap 403 to rotate.Coil cabin body 401 is fixed.The electric charge achieved like this on rotating parts is dredged to static component.Meanwhile, coil strap 403 is firm with the connection of hatchcover 402 and coil cabin body 401, thus ensure that the flowing of electric current is smoothly, can not be interrupted.
More than show and describe general principle of the present utility model, principal character and advantage.Those skilled in the art should understand; the utility model is not by the restriction of above-mentioned specific embodiment; description in above-mentioned specific embodiment and specification is just in order to further illustrate principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by claims and equivalent thereof.
