Description
Technical field
The present invention relates to technical field of wind power, particularly relate to a kind of wind-driven generator with special cable cabling mode.
Background technology
Along with wind-power electricity generation scale enters continuous expansion, adaptability and availability to wind power generating set are had higher requirement, its Leaf is prevented and kill off the vibration monitoring of ice and blade and is obtained the development advanced by leaps and bounds, but automatically become oar (subtended angle of blade can be automatically adjusted) with natural wind speed owing to big megawatt wind driven generator group mostly is, therefore, in blade, the power line of sensor and heater and holding wire cannot be fixed by conventional method.
Based on problem above, the production firm of present most of wind power generating set is set up by the power supply by blade and wheel hub of the connected mode of slip ring and communication.
It is known that, slip ring divides stator and rotor two parts, by conducting electricity raceway connection between stator and rotor, for ensureing good communication, raceway face requires must be gold-plated, therefore the costs rather expensive of slip ring, additionally, along with the continuous friction of slip ring raceway, Gold plated Layer is worn and torn quickly, will cleaning slip ring usual every half a year, and increase Gold plated Layer, maintenance cost and maintenance cost are all costly.
Summary of the invention
The wind-driven generator with special cable cabling mode it is an object of the invention to provide a kind of with low cost, failure rate is low, being easily maintained, (blade normally becomes propeller angle not over 90 °) can realizing the smooth and easy cabling of service cable and/or communication cable in blade limited angle rotating range, cabling mode is simple, safe and reliable.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of wind-driven generator with special cable cabling mode, including blade and wheel hub, electric terminal in blade is connected by cable with between the feeder ear in wheel hub and/or communication ends, described wheel hub is connected by elastomeric element with blade, and described cable is fixed on elastomeric element in the way of " curve ".
Further, described curve is serpentine curve.
Further, described elastomeric element one end is connected on wheel hub on the one side of blade interior, and the other end is connected on the manhole plate of blade interior.
Further, described elastomeric element is fixedly connected on wheel hub and manhole plate by hanger.
Further, described elastomeric element is spring.
Further, described cable is fixed on spring by band.
Owing to adopting technique scheme, the present invention at least has the advantage that
Although 1, present invention simple in construction, but solve in certain limit cable routing problem between reciprocating rotary parts and geo-stationary parts, by cable is fixed on elastomeric element by curve form, realize cable unit length occurs minimum torsion, and realize the fixing of cable, ensure the smooth and easy cabling of service cable and/or communication cable in blade limited angle rotating range.
2, compared with the connected mode that the routing technology of existing blade to wheel hub adopts slip ring, the present invention has the following advantages:
(1) cost is low.It is known that the price of the slip ring of 4 passages is at least about 130,000, and solving routing problem by the present invention, cost is at about 80 yuan, and cost declining effect is more apparent.
(2) failure rate is low.Slip ring connected mode is subject to the factor such as electromagnetic interference, mechanical part deformation affects communication and energising effect, and the present invention adopts purely mechanic connection, substantially can reach zero failure.
(3) easy care.Slip ring needs routine cleaning and maintenance, and the existence life-span of the Wiring structure in the present invention can reach maintenance-free substantially.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, below in conjunction with accompanying drawing, the present invention is described in further detail with detailed description of the invention.
Fig. 1 is the wind generator set blade external structure schematic diagram to wheel hub.
Fig. 2 is the wind-driven generator internal structure schematic diagram with special cable cabling mode of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, a kind of wind-driven generator with special cable cabling mode of the present invention, including blade 5 and wheel hub 7, electric terminal 6 in blade 5 is connected by cable with between the feeder ear in wheel hub 7 and/or communication ends, described wheel hub 7 is connected by elastomeric element 2 with blade 5, and described cable is to be fixed on elastomeric element 2 in the way of " curve ".
In order to be guaranteed in blade limited angle rotating range the smooth and easy cabling of service cable and/or communication cable, " curve " mode serpentine curve as shown in Figure 2 of described cable, i.e. pictograph curve of cyclical fluctuations of health when Serpentis creeps.Described cable is securable to elastomeric element 2 side or spiral surrounding is fixed on elastomeric element 2.Elastomeric element 2 can adopt spring.Cable can pass through band 3 and be fixed on spring.
Elastomeric element 2 can be connected on wheel hub 7 on the one side within blade 5 by hanger 1 one end, and the other end is connected on the manhole plate 51 within blade 5.
Specifically, when carrying out cabling connection, as shown in Figure 2, first on the suitable position of the manhole plate 51 within wheel hub 7 and blade 5, beat suitable screw thread and hole, hanger 1 is screwed on wheel hub 7 and manhole plate 51 respectively, then the hook of fixed length both ends of the spring is suspended to respectively on two hangers 1, then cable 4 is fixed on fixed length spring by the mode band 3 of " snakelike ", finally the two ends of cable 4 are respectively connected on the Electric Appliance Cabinet of wheel hub 7 and blade 5 on the electricity consumption element terminals 6 that arranges.
Owing to have employed above technical scheme, the invention solves in certain limit cable routing problem between reciprocating rotary parts and geo-stationary parts, by cable is fixed on elastomeric element by curve form, it is achieved cable unit length occurs minimum torsion, and realizes the fixing of cable.
The above; it it is only presently preferred embodiments of the present invention; not the present invention being done any pro forma restriction, those skilled in the art utilize the technology contents of the disclosure above to make a little simple modification, equivalent variations or modification, all fall within protection scope of the present invention.
