The invention relates to the technical field of wind power generation, and discloses a doubly-fed frequency converter with a mounting plate convenient to hoist. The doubly-fed frequency converter comprises a frequency converter body and the mounting plate, the mounting plate is fixedly arranged at the top of the frequency converter body, two limiting openings are symmetrically formed in the top ofthe mounting plate, and two adjusting rods are arranged in each limiting opening; and one end of each adjusting rod is movably provided with a round block, two strip-shaped grooves matched with the round blocks are symmetrically formed in the front side walls and the rear side walls of the two limiting openings, a first spring is arranged in each strip-shaped groove, the two ends of the first springs are fixedly connected with the side walls of the strip-shaped grooves and the side walls of the round blocks respectively, and a rotating shaft is arranged above the mounting plate. According tothe invention, the stability of the mounting plate and the frequency converter in a lifting process can be improved, a lifting hook and a lifting ring can be separated from each other conveniently, meanwhile, the multiple adjusting rods can be stored conveniently, and the overall attractiveness of the device is improved.

    本发明涉及风力发电技术领域,且公开了一种带有便于吊装的安装板的双馈变频器,包括变频器本体和安装板,安装板固定设置于变频器本体的顶部,安装板的顶部对称开设有两个限位开口,且两个限位开口内均设有两个调节杆,每个调节杆的一端均活动套设有圆块,两个限位开口的前后两侧壁均对称开设有两个与圆块相匹配的条形槽,每个条形槽内均设有第一弹簧,且第一弹簧的两端分别与条形槽的侧壁和圆块的侧壁固定连接设置,安装板的上方设有转轴。本发明能够提高安装板和变频器在吊装过程中的稳定性,且便于吊钩与吊环之间相互脱离,同时能够便于对多个调节杆进行收纳,提高装置整体的美观性。
