In order to solve the above technical problem, as shown in fig. 1 to 6, a first aspect of the present application provides a magnetic levitation rotor locking device, including: the two locking structures are respectively arranged between the magnetic suspension bearing 1 and the rotor 2 and used for limiting the rotor to move randomly in the inner cavity of the stator; the locking structure is formed by splicing a plurality of locking parts 3, in order to ensure that the stress of each locking part is equal, preferably, the sizes of the locking parts are equal, and exemplarily, as shown in fig. 1, in the embodiment, each locking structure is uniformly divided into 8 locking parts; the wall surface of the locking parts 3 close to the rotor 2 is a free end, and the wall surface far away from the rotor 2 is in telescopic connection with the inner cavity of the stator 6 through the driving arm 4 so as to drive the locking parts 3 to move towards the direction close to or far away from the rotor 2; among them, it is preferable that the driving arm 4 is a link or a robot arm.
As shown in fig. 1-3, when the magnetic levitation system is in a shutdown state or a transportation state, the plurality of locking portions are driven to move in a direction close to the rotor until the plurality of locking portions are spliced to form a locking structure to lock the rotor, so that the rotor is limited in the inner cavity of the stator by using the two locking structures, the situation that the rotor collides with the inner cavity of the stator in the transportation process is effectively avoided, and the normal operation of the magnetic levitation system is finally ensured; similarly, as shown in fig. 4-6, when the rotor is in the power-on state, only the locking portions 3 need to be driven to move in the direction away from the rotor until the wall surfaces of the locking portions 3 away from the rotor are in contact with the inner cavity of the stator, so that the rotor is released.

According to an embodiment of the present invention, in order to avoid the locking structure from scratching the rotor, it is preferable that the wall surface of the locking structure near the rotor 2 is provided with a protective layer.
According to one embodiment of the invention, a gravity sensor 5 is also embedded at the center of each locking portion 3; before the rotor rotates, the rotor needs to be statically suspended, that is, the rotor is gradually lifted to a preset suspension position from the lowest end, in the prior art, the rotor is lifted to the preset suspension position by using a magnetic suspension bearing under the action of a magnetic field, however, when the rotor is in an initial state, the magnetic suspension bearing is far away from the rotor, a large starting current is needed to generate a strong magnetic field to lift the rotor, the control process needs a power device with higher performance to support, so that the cost is increased, and the control logic for lifting the rotor by using the magnetic suspension bearing is complex and is easy to deviate, in order to solve the technical problems, the rotor is lifted to the preset suspension position by using the design of two locking structures in the embodiment, and the specific process is as follows: the rotor is locked under the action of the two locking structures, and the moving displacement of the locking part arranged below the rotor is larger than that of the locking part arranged above the rotor, so that the rotor is lifted to a preset suspension position, then when the current stress of the rotor is detected to be zero through the gravity sensor, the current position is determined to be the preset suspension position, and then the locking structures are driven again to release the rotor, so that the rotor can normally work at the preset suspension position, the rotor can be directly lifted to the preset suspension position through the design, the control process is simplified, the output current of a power device is effectively reduced, and the production cost is reduced.

step S101, if a starting signal is detected, driving a magnetic suspension rotor locking device to lift the rotor 2 to a preset suspension position; specifically, the movement displacement of the locking portion provided below the rotor is larger than the movement displacement of the locking portion provided above the rotor;
and S102, if the gravity sensor 5 detects that the stress of the rotor 2 is zero at present, the magnetic suspension rotor locking device is driven again to release the rotor 2, and the rotor 2 starts to work.
The specific working process is as follows:
at first drive two locking structure's a plurality of sticking portion all to the direction motion that is close to the rotor, until locking the rotor, and the removal displacement of the sticking portion that sets up in the rotor below is greater than the removal displacement of the sticking portion that sets up in the rotor top, at this moment, rotor below atress is greater than rotor top atress, thereby the realization is lifted the rotor to predetermined suspended position, later when detecting the current atress of rotor through gravity sensor and being zero, then confirm the current position and be predetermined suspended position, then drive two locking structure's a plurality of sticking portion all to the direction motion of keeping away from the rotor, until a plurality of sticking portion 3 keep away from the wall of rotor and stator inner chamber inconsistent can, thereby realize that the rotor can carry out normal work at predetermined suspended position.
According to an embodiment of the invention, the method further comprises: if a standby signal or a shutdown signal is detected, driving a magnetic suspension rotor locking device to drop the rotor 2 to an initial position;
specifically, when a standby signal or a shutdown signal is detected, the rotor is controlled to perform a shaft dropping operation, and the specific process is opposite to the process of lifting the rotor: the locking parts of the two locking structures are driven to move towards the direction close to the rotor until the rotor is locked, the moving displacement of the locking parts arranged above the rotor is larger than that of the locking parts arranged below the rotor, at the moment, the stress on the upper part of the rotor is larger than that on the lower part of the rotor, and therefore the rotor can be dropped to the initial position.
According to an embodiment of the present invention, before the step of driving the magnetic levitation rotor locking device to release the rotor 2 again when the gravity sensor 5 embedded in the locking part 3 detects that the current force on the rotor 2 is zero, the method further comprises:
acquiring a current displacement value by using a displacement sensor, and determining that the current suspension position is a preset suspension position if the current displacement value is equal to a preset displacement value;
if not, the current suspension position of the rotor 2 is adjusted by using the two locking structures.
The specific adjustment process is as follows:
firstly, two ends of the rotor are locked by using two locking structures, for example, when the current position of the rotor is detected to be too far left, the rotor is moved rightwards under the action of the two locking structures, the specific adjustment amount is determined according to the measured displacement value, and of course, the adjustment is carried out only through one locking structure according to the offset position.
