Description
Technical field
The utility model relates to a kind of loosing-proof device of wind-driven generator bus duct coupling assembling, belongs to the conductive equipment technical field of the delivery of electrical energy of wind power generation.
Background technology
Traditional delivery of electrical energy process general electric wire carries out, but along with expanding economy, the sharply increase of power consumption, causes the problems such as the capacity subbranch inconvenience of electric wire.In order to address this problem, in the distribution design such as building and wind generator system, the capacity that have employed is large, branch convenient, boundling manages bus duct system easily.
But in the use procedure of the bus duct of wind generator system, the various vibration of long-term existence and rocking, the busbar junction of bus duct easily loosens, faults such as there will be phase fault, loose contact, strike sparks, burn.
Utility model content
The purpose of this utility model be in order to provide a kind of structure simple, manufacture conveniently, the loosing-proof device of production efficiency is high, cost is low wind-driven generator bus duct coupling assembling, the busbar junction solving wind-driven generator bus duct easily loosens, faults such as there will be phase fault, loose contact, strike sparks, burn.
In order to achieve the above object, the utility model provides a kind of loosing-proof device of wind-driven generator bus duct coupling assembling, comprise shell clamping plate I, shell clamping plate II, be fixed on the interior laminated plank between shell clamping plate I and shell clamping plate II, for the screw bolt and nut of fixed housing clamping plate I, shell clamping plate II and interior laminated plank; Described nut is positioned at described shell clamping plate I and holds; The outer side center place of described shell clamping plate I and shell clamping plate II is all provided with a groove; Described nut is arranged with a packing ring, and this packing ring is positioned at the groove on described shell clamping plate I; Described packing ring is circular, and the center is provided with a through hole for fixing described bolt, its edge be circumferentially evenly provided with several sawtooth; In groove on described shell clamping plate I, be provided with the teeth groove matched with described sawtooth; Described sawtooth and teeth groove engage each other.
Further, in order to reduce the fixation pressure of sawtooth and teeth groove, in the course of work of routine, the firm of bus duct can be ensured, between described packing ring and shell clamping plate I and between the bolt head and shell clamping plate II of described bolt, a slice spring steel plate is installed all separately; Described two panels spring steel plate lays respectively in described two grooves.The spring steel plate installed between described packing ring and shell clamping plate I, the diapire of the groove on shell clamping plate I is close in its side, and opposite side is close to described packing ring.The spring steel plate installed between the bolt head and shell clamping plate II of described bolt, the diapire of groove is close in its side, and opposite side is close to the bolt head of described bolt.
Further, the center of described shell clamping plate I, shell clamping plate II and interior laminated plank is all provided with the through hole that the screw rod for described bolt passes through.
The beneficial effects of the utility model are: the loosing-proof device of wind-driven generator bus duct coupling assembling provided by the utility model, by the mechanical force that the shell clamping plate of the packing ring and spline with outer sawtooth stop produce, the reverse rotation of bolt is prevented to loosen, increase bolt for tight moment, ensure that the connection of bus duct is reliable.In bus duct coupling assembling, the deformation force of spring steel plate generally can ensure loosening of nut, but in long-term vibration environment, because the contact-making surface of bolt and spring steel plate is less, likely loosen, increase the effect can playing mechanical stop after there is the packing ring of outer sawtooth, ensure that the firm of nut; Meanwhile, because the groove number on the sawtooth number of packing ring and shell clamping plate I sets, can ensure that sawtooth is in groove on arbitrarily angled, ensure that in bus duct, the connection of busbar is reliable.
