Description
Technical field
The utility model belongs to generator set technical field, particularly relates to a kind of cable twist protective device for wind generating set.
Technical background
Current wind power generating set is when tackling the wind direction of change at random, and the strategy of employing is driftage and system of untying the mooring rope.This system is when wind direction often deflects several angle, and the same angle of blower fan corresponding deflection is to ensure that wind wheel is just to wind direction.Need to be transported to bottom surface by cable from cabin because of the electric energy sent from generator simultaneously, like this, blower fan is when accumulative rotation reaches several angle in a certain direction, twist into two parts in order to avoid power transmission cable is wound, so need a mechanism of untying the mooring rope to rotate to an angle round about continuously when blower fan rotates to limit position, with releases cable.The untie the mooring rope defect of mechanism of this driftage is: can be wound around several angle when the cable being suspended on tower cylinder is in order to go off course, so be free relaxed state, during fan operation, pylon rocks, the metal parts friction of unavoidable generation and surrounding, occurs that insulation rubber weares and teares and causes the accident of electric shock or fire.
Summary of the invention
For the technical problem of above-mentioned existence, the utility model provides a kind of cable twist protective device for wind generating set.
To achieve these goals, the technical solution of the utility model is:
A kind of cable twist protective device for wind generating set; comprise that cable holder is divided, cable guide pin bushing, guide pin bushing bracket and fixed base; described guide pin bushing bracket is fixed by the fixed base be installed on tower cylinder; conjunction cable guide pin bushing on guide pin bushing bracket; cable is placed in cable guide pin bushing and is divided by cable holder fixing, and the described cable holder component of rotation is connected to any direction in cable guide pin bushing and rotates.
Further, described cable holder is divided and is comprised cable clamp, bearing and coupling shaft, and on described cable clamp, criss-crossing is provided with coupling shaft, and coupling shaft two ends are connection bearing respectively.
Further, described cable clamp is made up of the both sides clamping plate of nonmetallic material, and after installing cables, both sides clamping plate are connected by adjusting bolt.
Further, described cable guide pin bushing bracket comprises yoke crosstie, guide pin bushing connecting plate, guide pin bushing folder, PVC board and rubber plate, described rubber plate, PVC board and guide pin bushing folder is two part-annulars, be set in turn in cable guide pin bushing outer ring from inside to outside, guide pin bushing folder both sides are connected on yoke crosstie respectively by guide pin bushing connecting plate.
Further, the side of the two halves annular plate of described cable guide pin bushing folder is also connected with guide rail, and described guide rail is positioned at rubber plate inner ring, is connected with the bearing fit that cable holder is divided.
The beneficial effects of the utility model are:
Avoid the electricity turning round required suspension in cable device in the utility model unit operation to wear and tear mutually, and the situation of beating cylindrical shell when occurring rocking when rocking with tower cylinder occurs.
Cable protection device of the present utility model is made up of nonmetallic material, alleviates overall weight.After installing cables, both sides clamping plate are connected by adjusting bolt, and these Integral cable clamping plate link bearing by coupling shaft, the guide rail on cable guide pin bushing rotates 360 °, can reach and better turn round cable effect.
Cable guide pin bushing bracket of the present utility model is solid by two Semicircular guide pin bushings clampings, between the rubber plate that arranges and PVC board, play the effect increasing frictional force, prevent guide pin bushing from twisting.
