Embodiment Construction

[0017] According to the specifications of the busway, the present invention has three structural forms including two sets of vibration-damping insulating elastic supports, three sets of vibration-damping insulating elastic supports and four sets of vibration-damping insulating elastic supports.

[0018] Now in conjunction with the accompanying drawings, take three groups of vibration-damping insulating elastic supports as an example to describe in detail.

[0019] A special bus duct vibration damping mechanism for wind power, comprising a bus duct 13, a bus duct cover plate 15, at least two sets of double-ended screws 1, in which a spring 3 is arranged; it also includes an L-shaped channel steel connecting seat 2, U-shaped channel steel 6, L-shaped channel steel 10, buffer insulating rubber shock absorber 7, the side of the L-shaped channel steel connecting seat 2 is connected with the bus duct cover plate 15, and the bottom edge of the L-shaped channel steel connecting seat 2 ...

Abstract

The invention discloses a damping mechanism for a bus duct special for wind power and belongs to the field of wind power. The problem that a bus duct body of an existing wind power bus duct is endangered due to fierce shaking of a tower drum is solved. The damping mechanism comprises the bus duct, a bus duct cover plate and at least two sets of double-thread screws. Each double-thread screw is internally provided with a spring. The damping mechanism further comprises an L-shaped groove steel connecting base, U-shaped groove steel, L-shaped groove steel and a buffer insulating rubber damper. The side edge of the L-shaped groove steel connecting base is connected with the bus duct cover plate. The bottom edge of the L-shaped groove steel connecting base is connected with the U-shaped groove steel through the double-thread screws. The buffer insulating rubber damper is fixed between the top surface of the U-shaped groove steel and the side edge of the L-shaped groove steel. According to the damping mechanism for the bus duct special for wind power, the bus duct can be effectively fixed, the effect that under the condition that a tower drum on the spot of a wind field fiercely shakes, a position error of a bracket in the tower drum wall can be eliminated while all unit loads of the bus duct are uniformly distributed is also ensured, and the structure influence of abnormal vibration of the tower drum on the bus duct also can be eliminated through a specially-made elastic component.

Description

technical field [0001] The invention belongs to the field of wind power, and in particular relates to a vibration damping mechanism for a bus duct dedicated to wind power. Background technique [0002] In recent years, with the development of domestic electric power, the capacity of wind turbines has been increasing, and the disadvantages of the transmission cables that transmit electric energy to them have become more and more obvious. The bus ducts dedicated to wind turbines will gradually replace them. At present, the spring support for vertical installation of bus duct in the market is only suitable for the construction field, but it is not suitable for the wind power site because of the harsh environment and the shaking of the tower, so it needs to have elastic support and three-dimensional adjustability. The bracket with the functions of anti-shock, anti-shake and anti-installation structure error of the bus duct can solve the harm to the bus duct itself. Contents of...
