[0002] Flywheel energy storage technology is a technology that converts electrical energy into mechanical energy for storage, and its core component is a high-speed rotating flywheel rotor.

DETAILED DESCRIPTION

[0022] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] As shown in Figures 1-4 the energy storage flywheel transportation protection locking device 1 of the present application, the energy storage flywheel includes the housing 2 and the flywheel rotor 3 arranged in the housing 2, and the protection locking device includes the fixing seat 6 and the locking member 7.

[0024] Specifically, the fixing seat 6 is connected with the housing 2 and has an assembly hole opposite to the end of the flywheel rotor 3, the locking member 7 is fitted at the assembly hole and detachably connected with the fixing seat 6, and the locking member 7 is eccentrically adjustable relative to the assembly hole, and the locking member 7 has the locking bolt 8 adapted to the lifting hole of the end of the flywheel rotor 3.

[0025] Therefore, when the flywheel rotor 3 is locked by the locking device of the present application, the position of the locking member 7 can be adjusted to enable the locking bolt 8 to be screwed into the lifting hole along the axial direction of the lifting hole, and after the connection between the locking member 7 and the flywheel rotor 3 is completed, the position of the locking member 7 is adjusted to center the flywheel rotor 3, so as to avoid the contact and collision between the flywheel rotor 3 and the protection bearing 5, thereby preventing the flywheel rotor 3 from being damaged by collision during transportation.

[0026] It can be understood that, compared with the traditional locking device, the locking piece 7 and the fixing seat 6 of the application are two detachable independent structural parts. In operation, the locking bolt 8 can be assembled with the flywheel rotor 3 first, and then the locking piece 7 and the fixing seat 6 are connected to complete the locking. Since the locking piece 7 and the fixing seat 6 can be eccentrically adjusted in the non-connected state, the locking piece 7 can be moved to control the locking bolt 8 to be opposite to the lifting hole according to the orientation of the lifting hole of the flywheel rotor 3, so that the locking bolt 8 will not be upwardly abutted against the flywheel rotor 3 when being screwed, thereby avoiding damage to the flywheel rotor 3. After the locking bolt 8 is assembled in place, the position of the locking piece 7 is adjusted to center the flywheel rotor 3, avoiding contact between the flywheel rotor 3 and the stator to prevent collision damage.

[0027] The energy storage flywheel transportation protection locking device 1 of the application, the fixing seat is connected with the shell 2 and has an assembly hole opposite to the end of the flywheel rotor 3, the locking piece 7 is fitted in the assembly hole and detachably connected with the fixing seat, and the locking piece 7 is eccentrically adjustable relative to the assembly hole. The locking piece 7 has a locking bolt 8 adapted to the lifting hole of the end of the flywheel rotor 3. Thus, when the flywheel rotor 3 is locked by using the locking device of the application, the position of the locking piece 7 can be adjusted according to the orientation of the lifting hole of the flywheel rotor 3 until the locking bolt 8 is opposite to the lifting hole, and then the locking bolt 8 is screwed and assembled. After the locking bolt 8 is assembled with the flywheel rotor 3, the locking piece 7 is adjusted again to reset to center the flywheel rotor 3. Finally, the locking piece 7 is connected with the fixing seat 6 to achieve the locking and fixing of the flywheel rotor 3. Since the locking piece 7 is eccentrically adjustable relative to the fixing seat 6, the position of the locking piece 7 can be adjusted before the locking bolt 8 is assembled to make the locking bolt 8 opposite to the lifting hole, so that the locking bolt 8 will not be upwardly abutted against the flywheel rotor 3 during screwing, thereby avoiding damage to the flywheel rotor 3.

[0028] Further, as shown in Figure 2 The fixing seat has an assembly groove, and the assembly hole is formed on the bottom wall of the assembly groove. The locking piece 7 includes a fixed plate 71 and a protruding part 72. The fixed plate 71 is fitted in the assembly groove and has an adjustment gap with the inner wall of the assembly groove. The protruding part 72 is provided in the assembly hole and has an adjustment gap with the inner wall of the assembly hole. The protruding part 72 has a mounting hole for the locking bolt 8. The end of the protruding part 72 away from the fixed plate 71 has a fitting groove adapted to the end of the flywheel rotor 3. Thus, when the locking piece 7 is connected with the flywheel rotor 3, the fixed plate 71 is clamped in the assembly groove, the protruding part 72 is provided in the assembly hole, and the end of the flywheel rotor 3 can be clamped in the fitting groove. The overall cooperation is compact and has good stability.

[0029] Further, the mounting groove is an annular groove, the assembly hole is a circular hole and is located at the center of the annular groove, the fixing plate 71 is a circular plate, the protruding part 72 is located at the center of the circular plate, and the mounting hole is located at the center of the protruding part 72. It should be noted that the flywheel rotor 3 needs to be kept stable during transportation, and any positional deviation may affect its balance, thereby causing the failure of the entire system. According to the above arrangement, when the locking part 7 is connected with the flywheel rotor 3 and is reset, it only needs to be ensured that the protruding part 72 is moved to the center of the assembly hole (at this position, the center axis of the mounting hole is collinear with the center axis of the assembly hole), so that the flywheel rotor 3 is determined to be in the middle position inside the flywheel stator 4 (that is, the center of the flywheel rotor 3 is aligned), thereby facilitating accurate support of the flywheel rotor 3 and avoiding positional deviation of the flywheel rotor 3.

[0030] Further, the bottom wall of the assembly groove is provided with an eccentric adjusting hole, the fixing plate 71 is provided with a connecting hole corresponding to the eccentric adjusting hole, and the eccentric adjusting hole and the connecting hole are connected through an eccentric bolt 9. In this way, the eccentric adjustment of the locking part 7 can be realized by screwing the eccentric bolt 9, which is simple and convenient to operate. Specifically, the screw rod of the eccentric bolt 9 is eccentrically arranged relative to the nut, so that rotating the nut can drive the axis of the screw rod to move along the circumference of the nut, thereby driving the locking part 7 to shift and realize eccentric adjustment.

[0031] Preferably, the eccentric adjusting holes are a plurality of holes arranged at intervals in the circumferential direction of the assembly groove.

[0032] Alternatively, at least two of the plurality of eccentric adjusting holes are located on different sides of the assembly hole in the radial direction of the assembly groove. In this way, the eccentric bolts 9 located on different sides can assist each other when adjusting the eccentricity of the locking part 7, thereby improving the adjustment accuracy.

[0033] Further, the bottom wall of the assembly groove is further provided with a plurality of fixing holes arranged at intervals in the circumferential direction of the assembly hole, the locking part 7 is provided with a plurality of threaded holes, and the locking part 7 and the fixing seat 6 are connected through a connecting bolt 10 passing through the threaded holes and the fixing holes. In other words, the connecting bolt 10 is used to connect the locking part 7 and the fixing seat 6, and the eccentric bolt 9 does not serve as a connecting part.

[0034] Further, as shown in Figure 3 The outer wall of the assembly groove is provided with at least two positioning marking lines 12 spaced apart in the circumferential direction thereof, the outer peripheral edge of the fixing plate 71 is provided with at least two identification marking lines 13 spaced apart in the circumferential direction thereof, and the included angle between adjacent positioning marking lines 12 is consistent with the included angle between adjacent identification marking lines 13. In this way, the positioning marking lines 12 and the identification marking lines 13 can serve as an identifier for eccentric adjustment. When the plurality of positioning marking lines 12 and the plurality of identification marking lines 13 correspond to each other during eccentric reset of the locking part 7, it can be determined that the locking part 7 is at the center position of the fixing seat 6 at this time, and it can be judged that the flywheel rotor 3 has realized center alignment.

[0035] Further, the current transportation method cannot record the collision of the flywheel rotor 3 during transportation, and the internal damage caused by the collision of the flywheel rotor 3 cannot be detected. Once the damaged flywheel is applied in actual production, it is likely to cause a safety accident. Therefore, how to determine whether the flywheel rotor 3 has experienced a collision during transportation is crucial.

[0036] Based on the above problems, the energy storage flywheel transportation protection locking device 1 further comprises a collision detection assembly, which comprises a power supply, a positive electrode lead, a negative electrode lead, a relay and a controller. The positive electrode lead and the negative electrode lead are connected to the positive electrode and the negative electrode of the power supply, respectively. The outer surfaces of the fixed seat 6 and the shell 2 are provided with insulating layers and reserved conductive connection points 11. The positive electrode lead is connected to the conductive connection point 11 on the fixed seat 6, and the negative electrode lead is connected to the conductive connection point 11 on the shell 2. The relay is arranged on the positive electrode lead, and the controller is connected with the relay. Since the flywheel rotor 3 is connected with the locking piece 7, and the locking piece 7 and the fixed seat 6 are both conductive metals, the flywheel rotor 3 is connected with the shell 2 and can conduct electricity. Therefore, when the flywheel rotor 3 collides with the flywheel stator 4, the positive electrode lead, the fixed seat 6, the locking piece 7, the flywheel rotor 3, the flywheel stator 4, the shell 2 and the negative electrode lead can form a path, and the current conduction can trigger the relay to emit a signal to the controller. The controller can record the signal to prove the collision of the flywheel rotor 3 during transportation, and then facilitate subsequent judgment to prevent the use of defective flywheels.
