[0027] With the accelerated development of new energy technologies, magnetic levitation flywheel energy storage technology has become increasingly mature. The flywheel energy storage system uses physical methods to store energy, and uses an electric / generating reciprocal bidirectional motor to achieve the mutual conversion and storage between electrical energy and the mechanical kinetic energy of the high-speed running flywheel. The flywheel energy storage system has the advantages of high energy density, high conversion rate of electrical energy and mechanical energy, fast charging speed, and maintenance-free. It has been widely used in fields such as power grid peak regulation and wind power generation.

[0028] When assembling magnetic steel in the magnetic bearing of the flywheel energy storage system, it is generally done manually or with manual assistance. During assembly, the magnetic steel is taken manually, and a magnetic isolation block is laid in the magnetic steel groove of the bottom plate or the flywheel. The assembler pushes the magnetic steel from one side to make it enter the magnetic steel groove, and then takes out the magnetic isolation block to complete the assembly of the magnetic steel.

When the hydraulic cylinder 72 is working, the cantilever 3 moves longitudinally relative to the magnetic bearing 2. Using the structure provided in this embodiment, the hydraulic cylinder 72 can control the cantilever 3 to rise and fall relative to the magnetic bearing 2, so that when the magnetic steel needs to be installed, the operating assembly on the cantilever 3 can be close to the surface of the magnetic bearing 2, or even docked with the magnetic bearing 2, which can improve the accuracy of installing the magnetic steel.

[0037] Furthermore, a hydraulic cylinder base 72a may be provided between the hydraulic cylinder 72 and the rotating shaft motor 71. One side of the hydraulic cylinder 72 abuts against the hydraulic cylinder base 72a and is indirectly connected to the rotating shaft motor 71, so that the cantilever 3 on the other side of the hydraulic cylinder 72 can rotate with the rotating shaft motor 71, while the hydraulic cylinder 72 and the rotating shaft motor 71 are relatively fixed, and the probability of damage to the rotating shaft motor 71 under the pressure of the hydraulic cylinder 72 is reduced.

[0038] In one embodiment, the magnetic steel assembly device 1 of the magnetic suspension bearing further includes a circular guide rail 81 and a slider 82, the number of the hydraulic cylinder 72 is two, the circular guide rail 81 is arranged on the outer periphery of the magnetic suspension bearing 2, and is concentric with the magnetic suspension bearing 2.

In addition, hydraulic cylinders 72 are provided at both ends of the cantilever 3, and the cantilever 3 can be vertically lifted and lowered relative to the magnetic suspension bearing 2 under the synchronous operation of the two hydraulic cylinders 72, which can improve the accuracy of installing the magnetic steel.

[0040] Furthermore, a hydraulic cylinder base 72a may be provided between the hydraulic cylinder 72 and the slider 82, and one side of the hydraulic cylinder 72 abuts against the hydraulic cylinder base 72a, indirectly connecting the slider 82, so that while the cantilever 3 on the other side of the hydraulic cylinder 72 can move along the circular guide rail 81, the hydraulic cylinder 72 and the slider 82 are relatively fixed, and the probability of damage to the slider 82 and / or the circular guide rail 81 under the pressure of the hydraulic cylinder 72 is reduced.

[0041] In one embodiment, the operating component includes at least one magnetic steel storage element 4, which is used to store magnetic steel.

A first opening 44 is provided on the inner wall of the storage space 43, and the first opening 44 connects the storage space 43 and the guide channel 46, and the end of the guide channel 46 away from the first opening 44 is arranged toward the surface of the magnetic bearing 2. The first direction X intersects with the second direction Y, and both point to the first opening 44.

[0043] Through the structure provided in this embodiment, the first push-pull member 41 and the second push-pull member 42 can be used to push the magnet in the storage space 43 along the first direction X and the second direction Y respectively, so that the magnet can be moved to the first opening 44 and fall onto the surface of the magnetic bearing 2 through the first opening 44 and the guide channel 46 for assembly, thereby improving the accuracy of the magnet.

[0044] Optionally, the first push member 41 may specifically include a first push block 411 and a first push cylinder 412, one end of the first push cylinder 412 is relatively fixed to the cantilever 3, and the other end is connected to the first push block 411, and the first push cylinder 412 can telescopically move along the first direction X, thereby driving the first push block 411 to move along the first direction X, thereby achieving the purpose of pushing the magnetic steel.

[0050] The adhesive storage member 5 can be fixed relative to the first linear motor 74 via the adhesive fixing block 5a. The adhesive storage member 5 can be fixed vertically or tilted downward to the adhesive fixing block 5a so that the adhesive in the adhesive storage member 5 can flow to the surface of the magnetic bearing 2 under the action of gravity.

[0051] In one embodiment, the adhesive storage member 5 includes an epoxy adhesive storage member 51, a curing catalyst storage member 52 and a gas pressure member.
