Problems solved by technology

[0003] However, the existing ultra-large wind power rotor workpieces have shortcomings. First, due to the unreasonable structural design of the rotor workpiece and the limitation of the intelligence of the assembly system, the rotor workpiece can only be pre-assembled and then transported to the coast. The components are transported to the coast for assembly, which not only makes the transportation difficult, but also greatly increases the transportation cost; the second is to install the permanent magnet directly on the rim of the rotor. This structure makes the

Embodiment 1

[0040] This embodiment is a super-sized wind power rotor workpiece. The rotor workpiece is a combined outer rotor structure, including six rotor module units distributed in an annular array. The outer diameter of the rotor workpiece is 0.8-3m.

[0041]In this embodiment, the rotor module unit includes a mounting block, a non-magnetic heat conducting strip 12 and a permanent magnet block 13 made of permanent magnets. The mounting block consists of a yoke plate 5, an inner arc-shaped sleeve plate 6, and an outer arc-shaped mounting plate 7 , The baffle plate 8, the first ear plate 10 and the second ear plate 11 constitute. Wherein, the yoke plate 5 has a fan-shaped plate structure, and its central angle is 60 degrees. The inner end of the yoke plate 5 is connected with an inner arc-shaped sleeve plate 6 , and the outer end is connected with a baffle plate 8 through an outer arc-shaped mounting plate 7 . The two sides of the yoke plate 5 are respectively provided with a first lu...

Embodiment 2

[0046] This embodiment is improved on the basis of Embodiment 1. The inner side of the non-magnetic heat-conducting strip 12 is preformed with an installation groove for easy installation of the permanent magnet block 13, and the outer side of the permanent magnet block 13 is provided with a two-dimensional code for marking its installation position. , the non-magnetic heat conduction strip 12 is made of transparent magnesia ceramic material which is convenient for observing the two-dimensional code on the outside of the permanent magnet block 13. The transparent magnesia ceramic material has the advantages of non-magnetic heat conduction and transparency, and the present invention innovatively uses it as a permanent magnet block Carrier.

[0047] A specific application of this embodiment is: the permanent magnet block 13 and the carbon steel rotor rim (that is, the installation area formed by the yoke plate 5, the outer arc-shaped installation plate 7, and the baffle plate 8) ...

Embodiment 3

Abstract

The invention belongs to the technical field of wind driven power generators, and particularly relates to a super-large-specification wind power rotor workpiece, and an intelligent assembly system and an assembly method thereof. The rotor workpiece is of a combined outer rotor structure and comprises a plurality of rotor module units distributed in an annular array, wherein each rotor module unit comprises a mounting block, a non-magnetic heat conduction strip and a permanent magnet block made of a permanent magnet, each mounting block is composed of a magnet yoke plate, an inner arc-shaped shaft sleeve plate, an outer arc-shaped mounting plate, a baffle, a first lug plate and a second lug plate, each magnet yoke plate is of a sector plate structure, the inner end portion of each magnet yoke plate is connected with the corresponding inner arc-shaped shaft sleeve plate, the outer end portion of each magnet yoke plate is connected with the corresponding baffle through the corresponding outer arc-shaped mounting plate, and the two side edges of the magnet yoke plate are respectively provided with a lug plate. The super-large-specification wind power rotor workpiece is of a combined outer rotor structure, and compared with traditional overall transportation, parts can be transported to the coast firstly and then assembled, so that the transportation difficulty is reduced while the transportation cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and in particular relates to a super-large wind power rotor workpiece, an intelligent assembly system and an assembly method thereof. Background technique [0002] In recent years, high magnetic energy permanent magnet technology has developed rapidly, especially the rare earth permanent magnet material NdFeB has been widely used in direct drive generators. The direct drive generator using permanent magnet technology has a simple structure and high efficiency. For the outer rotor permanent magnet direct drive wind power generator, the characteristic of the outer rotor motor is that the stator is fixed in the middle of the shaft, and the rotor rotates on the periphery of the stator, which is also a radial air gap magnetic flux structure. Compared with the inner rotor structure The position of the rotor and the stator is changed. The stator is called the inner stator inside the motor...
