Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, be further elaborated below in conjunction with the cable protecting device of drawings and Examples to wind turbine generator of the present utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2; the cable protecting device of the wind turbine generator of the present embodiment; comprise guard ring 1 and multiple cable hoop 2; guard ring 1 is the tubular structure of hollow; the through hole 11 that the end inwall of guard ring 1 being provided with some current supply cable hoops 2 is passed; the end winding support of cable hoop 2 or be connected on the outer wall of guard ring 1, forms the accommodation space 3 of attached cable 4 between the inwall of cable hoop 2 and guard ring 1.
In use, by be in wind turbine generator pendency section (such as cable from after cabin enters pylon with pylon with the part of axle sag several meters or tens meters) cable 4 pass from accommodation space 3, can be that one or a branch of cable 4 pass from accommodation space 3.In the present embodiment adopt three cables be a branch of, the shape of accommodation space 3 and three cables 4 suitable.The end winding support of cable hoop 2 or be connected on the outer wall of guard ring 1, thus cable 4 is clamped in accommodation space 3 by the inwall of cable hoop 2 and guard ring 1 jointly.The firm grip that cable hoop 2 and guard ring 1 pair of cable 4 can not only be made like this to be formed is reliable, and structure is simple, with low cost.
In practical application; this cable protecting device can be arranged on the cable 4 of pendency in cable back-up ring to the fixed position of cable 4; when waving appears in the cable 4 of section of dangling; by the interval action of guard ring 1; avoid between the cable 4 of pendency section and cable back-up ring or occur between cable and pylon colliding or rubbing, improve fail safe.
Particularly, the end of cable hoop 2 can be connected on the outer wall of guard ring 1, cable hoop can be made into U-shaped, two ends of cable hoop 2 are each passed through the different through hole 11 of on guard ring 1 two, two ends of cable hoop 2 all have screw thread, be provided with the nut that threaded engagement connects in the outer wall side of guard ring 1, the external diameter of nut is greater than the diameter of through hole 11.
In superincumbent structure; by two of cable hoop 2, there is screwing to act on and making cable hoop 2 be fastened on the inwall of guard ring 1 firmly by cable 4 of thread head and outer connected nut; also can be regulated by nut for tightness simultaneously; can either improve like this fixing fastness of cable 4, the fixed position being convenient to again to regulate cable protecting device on cable 4 and tightness.
It should be noted that cable hoop 2 can adopt metal material to make, certain deformability can be had like this and also possess certain tensile strength simultaneously, after cable is fixing, there will not be fracture.Preferably, cable hoop 2 and guard ring 1 have at least one to adopt non-permeable material to make, because cable 4 passes from the accommodation space 3 that inwall and the cable hoop 2 of guard ring 1 are formed, guard ring 1 and cable hoop 2 have one to adopt non-magnet material, so magnetic field would not be formed in accommodation space 3, thus the electric current generation electromagnetic interference avoided flowing through cable 4 produces eddy current loss, ensure the stability that cable 4 works.
Particularly, cable hoop 2 is multiple, and the quantity of its quantity and through hole 11 matches, and cable hoop 2 is the arrangement in two-dimensional array type on guard ring 1 axial and circumferential.Cable hoop 2 mentioned here along guard ring 1 axially (the multiple cable hoops being positioned at straight line axially arranged are considered as row) and circumference (being considered as a line along the same multiple cable hoops circumferentially arranged) upper to arrange in two-dimensional array type refer to multiple cable hoop 2 with formation cable hoop group arranged in columns on the axial direction of guard ring 1, and multiple row cable hoop group is along the circumferential array of guard ring 1, one or a branch of cable 4 can be fixed on the inwall of guard ring 1 in multiple position by multiple cable hoop 2 by each row cable hoop group like this, thus make the fixing more solid and reliable of cable 4, also avoid cable 4 to occur displacement in accommodation space 3 simultaneously.And multiple row cable hoop group can make multiple row cable hoop group be fixed many or multi-beam cable 4 along the circumferential array of guard ring 1, thus make multi-cable 4 can be formed as one group of cable, the resistance to wind can be strengthened like this, reduce the amplitude of fluctuation of cable 4.
More preferably, the multiple cable hoops 2 for fixing same cable are equidistantly arranged in the axial direction, and are located on the same line, the axis being parallel of this straight line and guard ring 1, can make so same or fixing point with a branch of cable 4 even, improve fixed effect.Circumferentially be spacedly distributed at same multiple cable hoops 2 of circumferentially arranging, many or multi-beam cable 4 can be made in guard ring 1 evenly and parallel arrangement, avoid the phenomenon occurring flow-disturbing each other to occur.
As a kind of embodiment, cable hoop 2 is provided with flexible insulating sleeve 5.The wearing and tearing of cable hoop 2 pairs of cables 4 can be reduced like this.Particularly, insulating sleeve 5 can be elastic insulating material, for preventing the phenomenon because of cable sheath breakage appearance electric leakage.
As a kind of embodiment, guard ring 1 inwall arranges insulated liner 12.In the steady job to cable 4, be separated with insulated liner 12 between on guard ring 1 inwall and between cable 4, avoid guard ring 1 inwall to the wearing and tearing of cable 4.Particularly, insulated liner 12 can be elastic insulating material, for preventing the phenomenon because of cable sheath breakage appearance electric leakage.
As a kind of embodiment, guard ring 1 is spliced by the arc section 13 that at least two are separated.Cable 4 is fixed on arc section 13 by cable hoop 2 being fixed Shi Kexian to cable 4; and then multiple arc section 13 is combined shape all-in-one-piece guard ring 1; the installation be convenient to very much between cable protecting device and cable 4 is fixed; as shown in fig. 1; comparatively preferably, guard ring 1 is spliced by two semicircular arc sections 13.
Particularly, be formed with the ear 131 with connecting hole 1311 of bending laterally in the end of arc section 13, the ear 131 of adjacent arc section 13 docks each other, is fixedly connected with by adjacent arc section 13 by the securing member through connecting hole 1311.Adjacent arc section 13 is fixedly connected with by the mode be bolted, and is conducive to the installation and removal of guard ring 1.
In sum, cable protecting device of the present utility model has following beneficial effect:
1) by cable hoop, multi-cable is fixed on the inwall of guard ring of tubular, makes multiple cable form one group, wind-force effect can be resisted, prevent the significantly swing of cable.
2) guard ring also can play the effect to cable protection, prevents tower wall or cable back-up ring from causing frictionally damage to cable.
3) by adopting the structure of cable hoop arrangement in two-dimensional array type on guard ring axial and circumferential, the fixing more solid and reliable of cable can be made, also avoid cable to occur displacement in accommodation space simultaneously, in addition, multi-cable can also be enable to be formed as one group of cable, the resistance to wind can be strengthened like this, reduce the amplitude of fluctuation of cable.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
