the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 6, the present embodiment provides a coil compression device of a box-type transformer of a wind turbine generator system, which includes a bottom plate 10, a top plate 20 and a threaded rod 30;

the bottom plate 10 and the top plate 20 are arranged in parallel, the screw rod 30 is movably penetrated through the top plate 20 and then is vertically fixed on the bottom plate 10, and a nut 301 is screwed on the part of the screw rod 30 higher than the top plate 20;

at least three pairs of dovetail slideway 40 are symmetrically arranged on the upper surface of the bottom plate 10 and the lower surface of the top plate 20, the dovetail slideway 40 on the upper surface of the bottom plate 10 is uniformly distributed around the center of the bottom plate 10, the dovetail slideway 40 on the lower surface of the top plate 20 is uniformly distributed around the center of the top plate 20, a dovetail slide block 50 is arranged along each dovetail slideway 40 in a sliding manner, and a jacking structure is arranged corresponding to each dovetail slide block 50.

It should be noted that, because the thickness of the dovetail slider 50 is greater than the height of the dovetail slideway 40, that is, the upper surface of the dovetail slider 50 on the bottom plate 10 is higher than the upper surface of the bottom plate 10, and the lower surface of the dovetail slider 50 on the top plate 20 is lower than the lower surface of the top plate 20, when the coil 70 is compressed, after the protruding dovetail slider 50 supports the main body of the coil 70, a space is left for the thread head 701 of the coil 70 at the respective middle positions of the bottom plate 10 and the top plate 20, so as to prevent the thread head 701 from affecting the compression effect.

This embodiment is through setting up dovetail slide 40 and dovetail slide 50, replaces original scattered coil cushion of placing to come chucking coil 70, when compressing the coil 70 of different models, only needs to slide dovetail slide 50 along dovetail slide 40 and utilize to corresponding position after the tight structure in top tightly can, simple structure, simple operation have avoided the cushion to easily lose, put the loaded down with trivial details scheduling problem of cushion, have improved compression efficiency more greatly.

As an example, the screws 30 are provided with at least two, and the at least two screws 30 are evenly distributed around the center of the base plate 10.

As an example, four screws 30 are provided.

As an example, four pairs of dovetail slides 40 are symmetrically disposed on the upper surface of the bottom plate 10 and the lower surface of the top plate 20.

By way of example, the tightening structure is a countersunk screw 60 vertically threaded on the dovetail slider 50, and an end of the countersunk screw 60 passes through the dovetail slider 50 and is in movable contact with an inner wall of the dovetail slideway 40.

When the dovetail slider 50 is pressed, the countersunk screw 60 is completely sunk into the dovetail slider 50 after the countersunk screw 60 is tightened.

As an example, the bottom plate 10 and the top plate 20 are both elliptical.

As an example, a copper sleeve 201 is disposed at a position through which the screw 30 penetrates on the top plate 20, and the screw 30 is movably inserted in the copper sleeve 201.
