Abstract
The invention relates to the technical field of wind-driven generators, in particular to a sealing and fixing device for a low-speed shaft core cable of a megawatt-level wind-driven generator. A low-speed shaft cable bundle of the device is fixed at an outlet on the lower sides of a hub and a hub cable through a cable fixing device and is sealed by a front-end cable sealing part, the low-speed shaft cable bundle is fixedly sealed at an inlet on the upper side of a slip ring through a slip ring side cable sealing part and comprises cables, isolation rubber rings and a cable packaging material, the cables are wrapped by the cable packaging material and tightly bundled, and the isolation rubber rings are mounted on the outer side of the cable packaging material at intervals of 200mm. By the aid of the sealing and fixing device, the cables in the whole path are firmly fixed and closely sealed and are prevented from wearing, shedding and displacing, connectors of the cables are prevented from being polluted by oil, and the shortcomings of easiness in wear, shedding, oil immersion and displacement of cables in an existing low-speed shaft core are overcome.
Description
Technical field:
The present invention relates to a kind of technical field of wind power generator, particularly a kind of MW class blower fan slow-speed shaft core cable seal fixture.
Background technology:
At present, wind-driven generator is as a kind of new forms of energy equipment, the develop rapidly and obtain widespread usage at home of its technology.The wheel hub of wind turbine generator is a rotating parts, and the cabin is a fixed part, and cable between the two need be through the slip ring switching.Normally move in the power generation process at blower fan, the power supply of pitch-controlled system and relevant control, feedback signal all rely on the cable in the hollow slow-speed shaft core that is through gear box to transmit in the wheel hub of front end rotation.This section cable will rotate with slow-speed shaft and wheel hub synchronously, and there is the many places bending in the threading path, so this section cable very easily weares and teares.The treating method that is adopted at present is that all cables are lashed to together, and the outside gum sprayed cotton band of going up insulation that twines is tied tight with adhesive tape, and is plugged with the foam block attached cable at the port that goes out lambda line.The method does not solve the problem that cable weares and teares, comes off, invades oil and play well, blower fan in the long-time running process existing because of cable wearing and tearing all the time, control system short circuit that causes or the potential safety hazard that opens circuit come off.
Summary of the invention:
The technical problem that the present invention will solve provides a kind of MW class blower fan slow-speed shaft core cable seal fixture; This device realized cable fixation in entire path, the sealing tight; Prevent the cable wearing and tearing, come off and play, avoid the cable interface place by oil pollution.The deficiency that the cable that has overcome existing slow-speed shaft in-core is easy to wear, come off, invade oil and play.
The technical scheme that the present invention taked is: a kind of MW class blower fan slow-speed shaft core cable seal fixture comprises cable fixture, front end cable seal, slow-speed shaft bunch of cables, slip ring side cable seal, isolates rubber ring and cable covering material; The front end cable seal is identical with slip ring side cable seal structure; Be uniformly distributed with a plurality of cableways and fastening bolt on the front end cable seal; The slow-speed shaft bunch of cables is fixed on the exit of wheel hub and wheel hub cable downside through cable fixture, and seals through the front end cable seal, and cable fixture comprises support arm; Have the installation screw hole on the support arm, have rubber ring in the hole in the middle of the cable fixture; The slow-speed shaft bunch of cables is through the porch of slip ring side cable seal sealing and fixing at the slip ring upside; The slow-speed shaft bunch of cables is made up of cable, isolation rubber ring and cable covering material; Cable covering material is wrapped in the cable outside and tightens cable, and the cable covering material outside is every to be equipped with an isolation rubber ring at a distance from 200mm.
The invention has the beneficial effects as follows: end installs cable fixture and cable seal additional in the gateway owing to having adopted in the present invention; Add the structure of external packing and rubber ring at cable; Thereby cable fixation in entire path, the sealing tight; Prevent the cable wearing and tearing, come off and play, avoided the cable interface place, ensure the stable operation of blower fan long-term safety by oil pollution.

Embodiment:
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6; A kind of MW class blower fan slow-speed shaft core cable seal fixture comprises cable fixture 1, front end cable seal 2, slow-speed shaft bunch of cables 3, slip ring side cable seal 4, isolates rubber ring 5 and cable covering material 6; Front end cable seal 2 is identical with slip ring side cable seal 4 structures; Be uniformly distributed with a plurality of cableways 7 and fastening bolt 8 on the front end cable seal 2; Slow-speed shaft bunch of cables 3 is fixed on the exit of wheel hub and wheel hub cable downside through cable fixture 1; And seal through front end cable seal 2, prevent in the wheel hub that cable stretches in the exit or drags slow-speed shaft bunch of cables 3 plaies; Cable fixture 1 comprises support arm 11, has on the support arm 11 screw hole 10 is installed, and with rubber ring 9, has cable wearing and tearing and the stressed effect of buffering cable bending of preventing in the hole in the middle of the cable fixture 1; Slow-speed shaft bunch of cables 3 is through the porch of slip ring side cable seal 4 sealing and fixing at the slip ring upside; Its effect is with cable tensioner sealing and fixing; Prevent 3 stretchings of slow-speed shaft bunch of cables or drag the porch cable; And prevent that the inner grease of gear box from flowing in the slip ring, avoids the porch cable from slip ring, to deviate from; Slow-speed shaft bunch of cables 3 is made up of cable, isolation rubber ring 5 and cable covering material 6; Cable covering material 6 is wrapped in the cable outside and tightens cable; It is aging to play the heat insulation cable that prevents; Cable covering material 6 outsides are every to be equipped with an isolation rubber ring 5 at a distance from 200mm, and slow-speed shaft bunch of cables 3 is not contacted with slow-speed shaft, prevents cable and slow-speed shaft relative wear.
It is understandable that; More than about specific descriptions of the present invention; Only be used to the present invention is described and be not to be subject to the described technical scheme of the embodiment of the invention; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention, to reach identical technique effect; As long as satisfy the use needs, all within protection scope of the present invention.
