Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Specific embodiment 1

As shown in Figures 1 to 6, a wind turbine converter maintenance toolbox includes an upper box 1, a lower box 2, a sponge 101, and a spare part sponge 201, and is characterized in that it also includes legs 5, Light strip 6, wheels 3, telescopic handle 4; the bottom of the lower box 2 is provided with wheels 3, and the other end away from the wheels 3 is provided with telescopic handle 4, and the side of the toolbox is provided with grooves, grooves Inner locking legs 5; the upper box 1 is provided with a sponge 101, and the sponge 101 is provided with grooves for various tools, and the inside of the sponge around the groove is provided with a light strip 6, A spare part sponge 201 is provided inside the lower box 2, grooves of different sizes are provided in the spare part sponge 201, and a battery pack 202 is provided at the bottom of the spare part sponge 201.
