Abstract
In a traditional wind generating set, power cables from a cabin part to a tower part are fixedly arranged on a U-shaped hanging board on a channel steel beam at the bottom part a cabin by mainly adopting cable sleeve net structures, and as the power cables are respectively bound by cable sleeve nets to form prints, and part of power cables are insufficiently centered, the power cables can be rubbed with a center bushing of a tower top platform during a skewing process, cable sheaths can be easily abraded, and great potential safety hazards are brought. The invention provides a power cable basket structure for a large-sized wind generating set. The power cable basket structure for the large-sized wind generating set comprises the U-shaped hanging board, a round basket, three supports and bolts, wherein the U-shaped hanging board is welded on the channel steel beam at the bottom part of the cabin, and the three supports are connected with the basket and the U-shaped hanging board. Through adopting such the power cable basket structure, the power cables are stressed by the inner wall of the round basket without the cable sleeve nets, and meanwhile, the round basket also plays a role of guiding the cables so as to ensure the power cables to be fully centered when reaching a tower from the cabin, and therefore, the power cable sheaths are protected from abrasion during the skewing process, and the safety of the wind generating set is improved.
Description
Technical field:
The present invention relates to a kind of Large-scale Wind Turbines power cable barrel structure.
Technical background:
In Large-scale Wind Turbines, between cabin and tower cylinder a large amount of power cables are arranged because blower fan needs driftage, cable must be respectively down to enter the tower cylinder from the cable rack of middle and both sides central.
In the existing wind turbine generator, enter tower cylinder part from the cabin at power cable, the main cable grip structure that adopts is fixed on power cable on the U-shaped boatswain chair on the base channel girder steel of cabin, bear power cable weight by cable grip, because power cable is subjected to the cable grip pulling force large, long-time stressed lower, the cable exocuticle can produce the very dark trace of strangling, and the two side portions power cable misaligns, center bush at driftage process medium power cable and tower cylinder top platform produces friction, cable sheath very easily weares and teares, and brings major safety risks.
Summary of the invention:
In order to overcome the defective of existing cable nets structure, the invention provides a kind of Large-scale Wind Turbines power cable barrel structure, this barrel structure mainly comprises: be welded in the U-shaped boatswain chair on the mainframe base channel girder steel of cabin, circular hanging basket, three supports that connect circular hanging basket and U-shaped boatswain chair, bolt.
Wherein, circular hanging basket is spliced by bolt by two semicircle hanging baskets, the convenient manufacturing and installation; Circular hanging basket is coaxial with the center bush of tower cylinder top platform, is up big and down small network structure, with the power cable tower cylinder center of leading; Link to each other by bolt between support and circular hanging basket, the U-shaped boatswain chair.
By adopting this power cable barrel structure; power cable is stressed by circular hanging basket inwall; need not cable grip; reduced the cable fixing link; avoided cable grip to strangle the appearance of trace, circular hanging basket also plays the cable guide effect simultaneously, can reach entirely on the center when guaranteeing power cable from the cabin to the tower cylinder; protection power cable epidermis is not is not worn and torn by center bush when driftage, improves the fail safe of wind turbine generator.

Among the figure: 1, right side cable rack; 2, intermediate cable frame; 3, left side cable rack; 4, mainframe; 5, tower cylinder top platform; 6, power cable; 7, central bush; 8, cable grip; 9, steel channel beam; 10, U-shaped boatswain chair; 11, circular hanging basket; 12, support; 13, bolt.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
The wind generating set structure that uses cable grip has been shown among Fig. 1, power cable (6) is from right side cable rack (1), intermediate cable frame (2), left side cable rack (3) enters respectively the tower cylinder, in this process, by cable grip (8) power cable (6) is fixed on the U-shaped boatswain chair (10) on the cabin base channel girder steel (9), because cable grip (8) need bear power cable (6) weight, and two side portions power cable (6) misaligns, very easily damage at wind turbine generator running medium power cable (6) exocuticle, damage mainly appears at dashed circle place among Fig. 1, and the damage meeting of power cable (6) crust brings great potential safety hazard to wind turbine generator.
Fig. 2 is the structure chart of Large-scale Wind Turbines power cable barrel structure of the present invention, this barrel structure mainly comprises: be welded in the U-shaped boatswain chair (10) on cabin mainframe (4) the base channel girder steel (9), circular hanging basket (11), three supports (12) that connect circular hanging basket (11) and U-shaped boatswain chair (10), bolt (13).
Wherein, circular hanging basket (11) is spliced by bolt (13) by two semicircle hanging baskets, is up big and down small network structure, with power cable (6) guiding tower cylinder center; Link to each other by bolt (13) between support (12) and circular hanging basket (11), the U-shaped boatswain chair (10).
Fig. 3; 4 is front view and the vertical view of Large-scale Wind Turbines power cable barrel structure of the present invention; as seen from the figure; circular hanging basket (11) is coaxial with the center bush (7) of tower cylinder top platform (5); by adopting this power cable barrel structure; power cable (6) is stressed by circular hanging basket (11) inwall; need not cable grip (8); reduced the cable fixing link; avoided cable grip to strangle the appearance of trace; circular hanging basket (11) also plays the cable guide effect simultaneously; can reach entirely on the center when guaranteeing power cable (6) from the cabin to the tower cylinder; protection power cable (6) epidermis is not is not worn and torn by center bush (7) when driftage, improves the fail safe of wind turbine generator.
Although through the present invention is described in conjunction with specific embodiments, for the skilled personage of the art, according to narration above make to substitute, revise with variation will be apparent.Therefore, substitute such, when modifications and variations fall in the spirit and scope of claim of the present invention, should be included in the present invention.
