Abstract
In the existing wind power generator set, the part of power cables from an engine room to a tower drum is fixed on a U-shaped lifting plate of a channel steel beam at the bottom part of the engine room by mainly adopting a cable net sleeve structure, and since the power cable is reined by the cable net sleeve to form reining marks and partial power cables are poorly aligned and generate friction with a central bushing of a top-part platform of the tower drum in the yawing process, cable sheaths are extremely easy to abrade so as to cause potential safety hazards. The utility model provides a lifting basket structure for the power cables of a large wind power generator set. The lifting basket structure comprises a U-shaped lifting plate, a round lifting basket, three brackets and bolts, wherein the U-shaped lifting plate is welded on a channel steel beam at the bottom of the engine room; and the three brackets are used for connecting the lifting basket and the U-shaped lifting plate. The lifting basket structure has the advantages that by adoption of the lifting basket structure, the power cables are stressed by the inner wall of the round lifting basket without cable net sleeves, the round lifting basket also plays a role in cable guidance simultaneously, so that the complete alignment of the power cables from the engine room to the tower drum can be guaranteed, the power cable sheaths are protected from being worn in yawing, and further the safety of the wind power generator set is improved.
Description
Technical field:
The utility model relates to a kind of Large-scale Wind Turbines and uses the power cable barrel structure.
Technical background:
In Large-scale Wind Turbines, between cabin and tower tube a large amount of power cables are arranged because blower fan needs driftage, cable must be respectively down to get into the tower tube from middle cable trough with both sides central.
In the existing wind power generating set, get into tower tube part from the cabin, mainly adopt the cable grip structure that power cable is fixed on the U type boatswain chair on the base channel girder steel of cabin at power cable; Bear power cable weight by cable grip; Because power cable receives the cable grip pulling force big, long-time stressed following, the cable exocuticle can produce the very dark trace of reining in; And the two side portions power cable misaligns; Center bush at driftage process medium power cable and tower tube top platform produces friction, and 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 utility model 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 connects three supports of circular hanging basket and U-shaped boatswain chair, bolt.
Wherein, circular hanging basket is spliced through bolt by two semicircle hanging baskets, the convenient manufacturing and installation; Circular hanging basket is coaxial with the center bush of tower tube top platform, is up big and down small reticular structure, with the power cable tower tube center of leading; Link to each other through bolt between support and circular hanging basket, the U-shaped boatswain chair.
Through 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 rein in the appearance of trace, simultaneously circular hanging basket also plays the cable leading role, guarantees that power cable can reach entirely on the center from the cabin during to the tower tube; Protection power cable epidermis is not is not worn and torn by center bush when driftage, improves the Security of wind power generating set.

Fig. 2 is a kind of structural drawing of Large-scale Wind Turbines power cable barrel structure;
Fig. 3 is a kind of plan view of Large-scale Wind Turbines power cable barrel structure;
Fig. 4 is a kind of plan view of Large-scale Wind Turbines power cable barrel structure.
Among the figure: 1, right side cable trough; 2, intermediate cable frame; 3, left side cable trough; 4, mainframe; 5, tower tube 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:
To combine accompanying drawing that the utility model is described further below.
The wind generating set structure that uses cable grip has been shown among Fig. 1; Cable trough (1), intermediate cable frame (2), left side cable trough (3) get into the tower tube respectively to power cable (6) from the right side; In this process, through cable grip (8) power cable (6) is fixed on the U type 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 power generating set 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 power generating set.
Fig. 2 is the structural drawing of the said a kind of Large-scale Wind Turbines power cable barrel structure of the utility model; 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 through bolt (13) by two semicircle hanging baskets, is up big and down small reticular structure, with power cable (6) guiding tower tube center; Link to each other through bolt (13) between support (12) and circular hanging basket (11), the U-shaped boatswain chair (10).
Fig. 3,4 is the plan view and the plan view of the said a kind of Large-scale Wind Turbines power cable barrel structure of the utility model; Visible by figure, circular hanging basket (11) is coaxial with the center bush (7) of tower tube top platform (5), through 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 rein in the appearance of trace; Circular hanging basket (11) also plays the cable leading role simultaneously; Guarantee that power cable (6) can reach entirely on the center from the cabin during to the tower tube, protection power cable (6) epidermis when driftage by center bush (7) wearing and tearing, the Security that improves wind power generating set.
Though through combining specific embodiment to describe to the utility model, for skilled personage in the present technique field, according to substituting of making of the narration of preceding text, revise with variation will be conspicuous.Therefore, substitute, revise and the spirit that changes the claim that falls into the utility model, should be included in the utility model when interior with scope such.
