Abstract
The utility model relates to a power transmission device of a wind generating set, belonging to the technical field of wind power generation. The power transmission device comprises a shaft sleeve and a supporting frame which mutually form a revolute pair, wherein the shaft sleeve is fixedly connected with a group of conductive rings which are arranged along the axial direction and mutually insulated from one another; the supporting frame consists of a carbon brush, a brush handle, a supporting rod and a connecting piece; and the carbon brush on the supporting frame electrically contacts with the excircle of the conductive rings on the shaft sleeve between two end plates. As the conductive rings and the carbon brush can make relative motion, a cable of a wind-driven generator can not be twisted in power transmission, thus completely avoiding the phenomenon of cable twisting, and the structure that the carbon brush contacts with the conductive rings from outside to inside not only leads electrical contact to be very reliable, but also greatly reduces the size of the conductive rings, and simplifies the structure of the conductive rings, therefore the manufacturing cost is decreased obviously.
Description
Technical field
The utility model relates to a kind of power transmitting device, and especially a kind of wind-driven generator power transmitting device belongs to technical field of wind power generation.
Background technique
In the horizontal axis wind-driven generator group working procedure, when the wind direction variation acquires a certain degree, the yaw system action of wind power generating set, rotate thereupon in the cabin, until aiming at wind direction (being commonly called as wind).In this process, the concentric cable of generator also rotates thereupon.When to the wind number of times more for a long time, may cause the cable stranded cable.Therefore, behind driftage accumulation one fixing turn (being generally the 2.5-3 circle), must untie the mooring rope, otherwise can cause the cable strand disconnected, cause shutting down.
For a long time, the measure that addresses the above problem is to adopt to untie the mooring rope and turn round the cable protection device.When this device detects cable and reaches the twisting angle of regulation when the driftage counter; send the signal that unties the mooring rope, control system will be sent temporary transient halt instruction, make the yaw motor of yaw system drive whole cabin simultaneously and enclose by opposite spin 2.5-3; get back to the center initial position, finish and untie the mooring rope.Afterwards, recover proper functioning more again.Though this type of prior art is applied, not only system complex, power consumption is big, efficient is low, will temporarily shut down when untying the mooring rope, and facts have proved; when the driftage counter lost efficacy; cable layup can threaten unit safety operation, can cause emergency shutdown when serious, or major accident occur.
For addressing the above problem, the applicant number of filing an application is 200910035371.2 and 200920236057.6 Chinese patent application, discloses a kind of wind-driven generator rotating contact power transmission device, and this device comprises the rotating shaft that is connected with engine rooms of wind power generators; Described rotating shaft and one group of radial arm that touches are connected, and are bearing in the pylon; The conductive contact that is electrically connected with generator is equipped with in the described outer end of touching arm; The outer end of described conductive contact constitutes revolute pair with the annular insulating guide rail that is fixed in the pylon, and electrically contacts with the conductive hoop that is fixed on output electric energy in the ring-shaped guide rail.Though this structure can fundamentally avoid turning round the cable phenomenon, its conductive hoop cost is higher, is unfavorable for applying.
The model utility content
The purpose of this utility model is: the shortcoming at above-mentioned prior art exists, a kind of wind power generating set power transmitting device that not only can avoid turning round cable phenomenon and cost economy is proposed, thus easy to utilize.
In order to reach above purpose, wind power generating set power transmitting device of the present utility model comprises the axle sleeve and the bearing support of mutual formation revolute pair; Described axle sleeve is fixedlyed connected with the conductive hoop of one group of mutually insulated of arranging vertically; Described bearing support is made of carbon brush, brush carrier, strut and link; Carbon brush on the described bearing support and conductive hoop cylindrical electrically contact.
The utility model further improves, link on the described bearing support comprises hinged fixing splayed shape two brush arms that are of an end and bearing support, and being loaded on the elastic component that described brush arm middle part keeps carbon brush and conductive hoop to electrically contact, the other end of described brush arm is fixed with the brush carrier that carbon brush is housed.
During use, have dual mode to select, a kind of is that cabin with axle sleeve and wind power generating set is in transmission connection, and with bearing support and pylon relative fixed; Another kind is that the cabin with bearing support and wind power generating set is in transmission connection, and with axle sleeve and pylon relative fixed; Take the circumstances into consideration respectively again the cable of wind-driven generator is electrically connected with conductive hoop or carbon brush.Because conductive hoop and carbon brush can relative movement, therefore during electric power transfer, the cable of wind-driven generator can not twist, thereby thoroughly avoided turning round the cable phenomenon, and the structure of carbon brush ecto-entad contact conductive hoop not only make electrically contact very reliable, and the conductive hoop size reduces greatly, and structure also obtains simplifying, thereby manufacture cost obviously reduces.
