Through the description of carrying out below in conjunction with the accompanying drawing that an example exemplarily is shown, above-mentioned and other purposes and the characteristics of the utility model will become apparent, wherein:
Fig. 1 is the stereogram that illustrates according to first embodiment's of the utility model cable transition apparatus;
Fig. 2 illustrates many cables to be installed in the schematic representation on the cable transition apparatus;
Fig. 3 is the stereogram that illustrates according to second embodiment's of the utility model cable transition apparatus.
Embodiment
Below, specify the embodiment of the utility model with reference to accompanying drawing.
Embodiment 1
Fig. 1 is the stereogram that illustrates according to the cable transition apparatus of first embodiment's of the utility model wind-driven generator; Fig. 2 illustrates many cables to be installed in the schematic representation on the cable transition apparatus.
As shown in Figure 1, comprise the backplate 2 at the two ends of cable bracket 1 and carrying cable carriage 1 according to first embodiment's of the utility model cable transition apparatus 10.As illustrated in fig. 1 and 2, cable 8 can be placed on the cable bracket 1, forms the U-shaped shape of the recurvation of dangling with this.Cable 8 can be guided to tower wall (not shown) by cable bracket 1, and then extends to ground along cable clamping device.The cross section of cable bracket 1 is inverted U-shaped; Comprise curved portion 11 and respectively from the two ends of curved portion to two low ends 12 that extend below, wherein, inboard low end 12 near the tower wall but and keep certain interval between the tower wall; Between tower wall and cable bracket, to hold cable; And compare with the low end 12 of inboard, the low end 12 in the outside is far away apart from the tower wall, to guide the cable that dangles 8 into Ta Bi through curved portion 11.Because cable bracket 1 has slick and sly shape, but so the cable natural torsion, can not lose cable.As shown in Figure 1, curved portion 11 and two low ends 12 can form.Preferably, curved portion 11 can have semicircular in shape.
Cable bracket 1 can directly be permanently connected with backplate 2 and be in the same place, for example through welding, riveted joint, bolt connection etc.In addition, also can cable bracket 1 be connected with backplate 2 by connecting plate 3.Specifically, connecting plate 3 is separately positioned on the end surfaces of cable bracket 1, and cable bracket 2 is fixed together with connecting plate 3.
As shown in Figure 1, on backplate 2, form hole 21, on connecting plate 3, form corresponding hole (not shown), to pass screw rod 5.Utilize nut 6, packing ring 7 and screw rod 5 that backplate 2 and cable bracket 1 are combined into one, then with this transition apparatus integral installation to the pylon of wind-driven generator.
Preferably, hole 21 is a slotted hole, with convenient distance of regulating between cable bracket 1 and the pylon, thereby regulates the gap that is placed between cable bracket 1 and the pylon according to the quantity of cable, and is good with the heat radiation that guarantees cable.On the other hand, also can be through regulating the distance between cable bracket 1 and the tower wall at formation slotted hole on the connecting plate 3.
In addition,, promptly there is bigger installing space between two drooping sections 12, therefore can realizes convenient installation the between connecting plate 3 and the backplate 2 because the bottom of cable bracket 1 is opened wide.
In order to reduce cable, on each low end 12 of cable bracket 1, can form at least one cable constraint portions for adapting to reversing significantly or waving of going off course and carry out.Shown in Fig. 1 and Fig. 2, the cable constraint portions can comprise hole 121 that is formed on the low end 12 and the band (not shown) that passes hole 121.Band capable of using passes hole 121 cable 8 is fixed or is strapped on the outer surface of low end 12.Yet; The invention is not restricted to this; Since the degree of waving of the cable between cable bracket 1 and the tower wall not the cable in the outside of cable bracket 1 to wave degree big, therefore formation cable constraint portions on the low end in the outside only can obtain good effect equally.
Preferably, can on each low end 12, the multirow hole be set, realizing multiple fixing to cable 8, thereby reduce the shaking amplitude of cable 8.
Because the bottom of cable bracket 1 is opened wide, so can realize easily the constraint of cable is installed.For fear of or the end of reducing cable and low end directly contacts and cable is worn and torn, can be with the lower limb of low end inside bend towards cable bracket 1.
Preferably, low end 12 can extend beyond backplate 2 downwards, to avoid the friction between cable 8 and the backplate 2.
In addition, in order to protect cable and to reduce wear, also can on two backplate inboards respect to one another, lay elastic material 4.Preferably, elastic material can adopt bipeltate, foam, soft cloth or leather etc.
Fig. 3 is the stereogram that illustrates according to second embodiment's of the utility model cable transition apparatus 10 '.
Different with first embodiment, the cover plate 15 of second embodiment's wavy cross-section capable of using retrains cable.Particularly, can on cover plate 15, form at least one groove of arranging vertically, and cover plate 15 removably is connected with low end 12.Cable 8 can be housed inside in the cable passage that is formed by groove on the cover plate 15 and low end 12 common sealings, thereby realizes fixing cable 8.
Preferably, because cable 8 has circular cross-section usually, so also can be at the corresponding groove of groove on formation and the cover plate 15 on the low end 12, to hold cable better.
Embodiment 3
Different with second embodiment with first embodiment, the 3rd embodiment can replace hole and band or cover plate and utilize the mode of elasticity C shape ring to fix cable.That is, the middle part of at least one C shape ring of rubber-like can be fixed to low end, blocks cable so that C shape is encircled horizontal arrangement, thereby reduces the rocking tendency of cable.Similarly, multirow C shape ring can be set on each low end also, to strengthen fixing to cable.
Above embodiment define the mode of different constraint cables, but the utility model is not limited thereto, and also can adopt other restraint device, for example, can adopt the constraint bar that is connected to low end etc.Particularly, the constraint bar can be connected on the low end by card, extension or bolt, with the constraint cable.
Through above-mentioned description; According to the embodiment's of the utility model wind-power electricity generation cables transition apparatus since the bottom of cable bracket open wide; And extend downward vertically; So through combining the cable constraint portions not only can reduce the amplitude of fluctuation of cable, the collision of minimizing and backplate and cat ladder, and also simple and compact for structure, easy for installation.
The utility model is not limited to the foregoing description, under the situation that does not break away from the utility model scope, can carry out various distortion and modification.
