Abstract
The utility model discloses an outlet cable fixing device, which belongs to the aerogenerator field. The outlet cable fixing device comprises a base and a sleeve. The base comprises a base body and a bottom plate located on the bottom of the base body. A plurality of lead grooves parallel to the axial direction of the base body and axially penetrating the bottom plate are uniformly distributed on the rotary face of the base body. The outlet cable fixing device can prevent an outlet cable from suffering centrifugal swings due to the rotary inertia of a coil wound rotor and increase the consistency and accuracy of rotary inertia measuring results of the coil wound rotor.
Description
Technical field
The utility model relates to a kind of outlet cable fixture for the wind-driven generator field.
Background technology
Present wind-driven generator adopts mostly is the form that wound rotor adds collector ring, namely belongs to the wound rotor generator.Described wound rotor links to each other with described collector shell by its axial end.The multiply stube cable is arranged on the described wound rotor, and namely the outlet cable stretches out, and in described wound rotor dynamic balance checking process, these cables can be transferred whipping with the high-speed rotary of described wound rotor, have affected the correct mensuration to the coiling rotor moment of inertia.Measure exactly for the moment of inertia to described wound rotor, present solution is: when described wound rotor was carried out rotation inerttia, with rope the outlet cable being tied up became bunch of cables.Yet because the rotatory inertia of described wound rotor, centrifugal whipping occurs in this bunch of cables at random, causes the described wound rotor moment of inertia that at every turn records all inconsistent.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of outlet cable fixture to be provided, and it can solve in the coiling rotor dynamic balancing trimming process, technical problem that can't Measurement accuracy wound rotor moment of inertia.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of outlet cable fixture, comprise pedestal and sleeve, described pedestal comprises base body and is positioned at the chassis of described base body bottom, the axially parallel of uniform some and described base body on the surfaces of revolution of described base body, and axially run through the wire lead slot on described chassis.
Further, on the bottom surface on described chassis, along the circumference on described chassis, uniform N bottom bolts hole.
Further, this fixture also comprises the top bolt, and the center of described sleeve blind end is provided with bolt hole, and the center of described base body end face is provided with the top bolt hole.
Adopted the technical scheme of a kind of outlet cable fixture of the present utility model, i.e. uniform some and described base body axially parallel on the surfaces of revolution of this fixture base body, and axially run through the technical scheme of the wire lead slot on chassis.Its technique effect is: prevent the outlet cable owing to the rotatory inertia of wound rotor, and centrifugal whipping occurs at random, improved consistency and accuracy to coiling rotor moment of inertia measurement result.
Description of drawings
Fig. 1 is the decomposition texture schematic diagram of a kind of outlet cable fixture of the present utility model.
Fig. 2 is the use schematic diagram of a kind of outlet cable fixture of utility model.
Fig. 3 is the overall schematic of a kind of outlet cable fixture of utility model.
Embodiment
See also Fig. 1, Fig. 2 and Fig. 3, inventor of the present utility model, below by specific embodiment and is described in detail by reference to the accompanying drawings in order to understand the technical solution of the utility model better:
See also Fig. 1, a kind of outlet cable fixture of the present invention comprises pedestal 1, sleeve 2 and top bolt 3.
Described pedestal 1 comprises base body 11 and is positioned at the chassis 12 of described base body 11 bottoms, on the surfaces of revolution of described base body 11, be the axially parallel of uniform some and described base body 11 on the side of described base body 11, and axially run through the wire lead slot 13 on described chassis 12.
Because the quantity of present wind-driven generator outlet cable 4 mostly is the six roots of sensation, per two outlet cables 4 form one group of outlet cable 4, so in the present embodiment, the quantity of described wire lead slot 13 is three.One group of outlet cable 4 of every described wire lead slot 13 interior arrangements.During installation, described outlet cable 4 enters described wire lead slot 13 from the bottom surface on described chassis 12.
Since on the axial end of the wound rotor that links to each other with collector ring of wind-driven generator with the screwed hole of a plurality of fixedly collector rings, on the bottom surface on the chassis 12 of described pedestal 1, along 12 a circumference uniform distribution N bottom bolts hole 14, described chassis, the position in described bottom bolts hole 14 should be consistent with the screwed hole on the described wound rotor axial end with size.In the present embodiment, described bottom bolts hole 14 is through hole.After described outlet cable 4 is introduced into wire lead slot 13, the bottom surface on chassis 12 of described pedestal 1 and the axial end of described wound rotor are fitted tightly, screwed hole on the axial end of described bottom bolts hole 14 and described wound rotor aligns, and then with bottom bolts described chassis 12 is fixed on the axial end of described wound rotor.
Then openend and the described base body 11 with described sleeve 2 is socketed, for described outlet cable 4 being fixed, the internal diameter of described sleeve 2 must match with the external diameter of described base body 11, and namely the internal diameter of described sleeve 2 must be slightly larger than the external diameter of described base body 11.The internal diameter of described sleeve 2 is too small, and described sleeve 2 can't be finished socket, and the internal diameter of described sleeve 2 is excessive, and described outlet cable 4 can't be fixed.
For described sleeve 2 and described pedestal 1 being fixed, the center of described sleeve 2 blind ends is provided with bolt hole 21, and the center of the end face of described base body 11 is provided with top bolt hole 15.In the present embodiment, described top bolt hole 15 is blind hole.The size of described bolt hole 21 and described top bolt hole 15 is corresponding with top bolt 3.After described sleeve 2 and 1 socket of described pedestal, the center of circle of the center of circle of described bolt hole 21 and described top bolt hole 15 overlaps, and described pedestal 1 and described sleeve 2 can be fixing by described top bolt 3.
Synergy by described pedestal 1 and described sleeve 2, described outlet cable 4 is fixed in the described wire lead slot 13, described like this outlet cable 4 just can not be owing to the rotatory inertia of described wound rotor, and centrifugal whipping occurs at random, improved consistency and accuracy to coiling rotor moment of inertia measurement result.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
