Embodiment
Refer to shown in Fig. 1; a kind of cable twist protective device for wind generating set of the present utility model; comprise fixed support 2, limit collar 3, cable cover(ing) 4 and restriction pallet 6; limit collar 3 is fixed on fixed support 2; cable cover(ing) 4 is placed in limit collar 3 inside; the external diameter of cable cover(ing) 4 is less than or equal to the internal diameter of limit collar 3; the height of cable cover(ing) 4 is greater than the height of limit collar 3; restriction pallet 6 is outside and cover on limit collar 3 around cable cover(ing) 4, and cable cover(ing) 4 outsides are provided with and limit that pallet 6 coordinates in case the parts that on-slip falls.
Because turn round the cable length of cable, be approximately 9-10m, the position of cable amplitude of oscillation maximum is in cable bottom, and swings and be only effective method in the restriction of the position of cable amplitude of oscillation maximum.So the utility model mounting point is preferably turned round cable platform at wind power generating set top section tower cylinder and is hung on the guardrail of thing hole.As shown in Figure 2, turn round cable platform and hang thing hole guardrail 1 near cable bottom, can effectively limit swing, and easy for installation, and installation personnel can stand on to turn round on cable platform and install.
Please refer to Fig. 3, fixed support 2 hangs on thing hole guardrail 1 in order to whole device is fixedly installed in, and rises and connects supporting effect.Fixed support 2 is inverted L shape, and the vertical beam of L is fixedly connected with hanging thing hole guardrail 1 use U bolt, should be noted that the vertical placement that keeps vertical beam during installation, checks that whether guardrail is firmly stable; The horizontal beam of L is fixedly connected with limit collar 3 by connecting plate 5.
Please refer to Fig. 4, Fig. 5, the horizontal beam of the fixed support 2 of connecting plate 5 one end and inverted L shape is fixedly linked, the other end and limit collar 3 welding.Connecting plate 5 is the steel plate with 2 row's U bolt holes, on the horizontal beam of L, correspondence is provided with a plurality of screws, 6 of connecting plate 5 use are bolted to down on the horizontal beam of fixed support 2 of L, can be arranged on screw on the horizontal beam of fixed support 2 by adjusting and regulate distance between limit collar 3 and the vertical beam of fixed support 2 (as the distance that is s of adjustable length in Fig. 5), consider the sagging position of cable, distance arranges the relative position that can regulate between cable cover(ing) 4 and limit collar 3 herein, should make cable cover(ing) 4 outer walls reach 30mm to limit collar 3 and the distance of the joint of connecting plate 5.
Please refer to Fig. 6, limit collar 3 is connected with bolt by two blocks of left and right semicircle tubular steel plate, surrounds cylinder-like structure.Cable cover(ing) 4, in order to banding bunch of cables, passes from limit collar 3 centers, cable flexing is limited in the cylindric scope of limit collar 3.Limit collar 3 requires through removing burr, wedge angle processing, and sharp edge needs fillet to process.During installation, with 6 groups of bolts, left and right two halves are embraced and are screwed in together, after tightening, check and whether occur becoming flexible.
Please refer to Fig. 7, cable cover(ing) 4 is also divided into left and right two-part, during installation, first left and right two-part is fastened to bunch of cables, then tights a bolt and connects into cylindrical shape sheath.Limit collar 3 only dwindles the scope of cable flexing and cable still can directly contact with limit collar 3; therefore the bunch of cables in limit collar 3 scopes is protected with cable cover(ing) 4; the height that cable cover(ing) 4 is set is greater than the height of limit collar 3, prevents that the limit collar 3 of cable and steel material from colliding with.The height that cable cover(ing) 4 exceeds limit collar 3 top and the bottom is preferably identical, be preferably limit collar Shang Xia 3 the cable cable sheath 4 in 100mm interval waled.
Because cable thickness is different, preferably tiny cable is placed on to skin when mounted, thicker cable is placed in internal layer, place so that fixing bolt is installed more quickly and easily like this, when fixing bolt is installed, attention is tightened bolt jail after will bolt being all arranged on cable cover(ing) 4 again, to prevent crooked situation.
During practical application, have a special DP optical fiber cable encasing with flexible pipe, through test, this optical fiber cable, when being installed to outside, easily blocks cable when blower fan is worked, and affects.So need when mounted an optical fiber cable to pack in the lump in cable cover(ing) 4, because outer fiber has hose proof protection, can not impact himself work.
Please refer to Fig. 8, restriction pallet 6 forms upper and lower two-layer ring dish by 4 semicircle annular slab splicings, bilevel apposition position cross-distribution is also installed up and down by bolt, during installation, need to, all bolton, prevent the damage in blower fan intensive work.Restriction pallet 6 internal diameters are a bit larger tham the external diameter of cable cover(ing) 4, in cable cover(ing) 4 arranged outside, have anti-sliding parts, as hanger, can be stuck in restriction pallet 6 tops, prevent the downward landing of cable cover(ing) 4.During installation, note the ear stud of inner side cable cover(ing) 4 upper ends being placed on to the top of restriction pallet 6, object is to prevent that inner side cable cover(ing) 4 from gliding.Meanwhile, restriction pallet 6 diameters are greater than limit collar 3 diameters, and it can not come off from limit collar 3.The cable cover(ing) preferred ultra-high molecular weight polyethylene of 4 material (UHMWPE), the restriction pallet 6 material selections material identical with cable cover(ing) 4.
Owing to having adopted above technological scheme, cable twist protective device for wind generating set of the present utility model, structure stability is good, easy for installation, cost is low, and can limit the amplitude swinging when cable is turned round cable, reduces to clash into occur, thereby effectively protects cable.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
