The push rod 55 is designed in a T shape.

[0035] During operation, the magnetic levitation flywheel energy storage device in the prior art needs to be regularly maintained to ensure that the device can operate stably and efficiently for a long time. Since the magnetic levitation flywheel energy storage device is fixedly installed inside the installation cabinet and occupies a large space, and the space inside the installation cabinet itself is relatively limited, it is inconvenient during maintenance and inspection. Through the structural design of the removal mechanism, the function of facilitating the removal of the mobile platform 22 together with the entire device body 1 from the inside of the installation cabinet 20 is realized, so as to free up a larger space for maintenance and inspection of the device body 1. When the device body 1 is to be maintained and inspected, first, after the cabinet door of the installation cabinet 20 is opened, since the front end of the top rod 42 is not abutted by the cabinet door, the fixing mechanism will release the fixation of the rotating disk 31, and the rotating disk 31 can rotate normally. A notch 32 is provided at the front end of the support base 21, and the notch 32 is used to It is convenient to rotate the rotating disk 31 inside the supporting base 21. By rotating the rotating disk 31 clockwise, the gear 29 on the rotating shaft 30 is driven to rotate. The gear 29 is meshed with the rack 28, so the rack 28 will move inside the long groove 64. As the rack 28 continues to move forward, the long block 26 connected to the rack 28 can drive the mobile platform 22 to slide on the groove 25, thereby moving the device body 1 fixed on the mobile platform 22 out of the installation cabinet 20, so as to facilitate maintenance and inspection of the device body 1. In order to ensure the stable movement of the mobile platform 22 during the sliding process, sliders 23 are fixed on both sides of the mobile platform 22. The sliders 23 will abut against the inner wall of the slide groove 24 to support the mobile platform 22, reduce the pressure that the long block 26 and the rack 28 need to bear, and also limit the movement of the mobile platform 22 in the left and right directions.

[0036] Through the structural design of the fixing mechanism, when the cabinet door 20 is installed, the multiple groups of card blocks 34 fixed on the connecting plate 37 can fix the rotating disk 31 by engaging with the card slots 33, ensuring that the rotating disk 31 does not rotate, and when the cabinet door of the installing cabinet 20 is opened, the engagement between the card blocks 34 and the card slots 33 is released to facilitate the normal rotation of the rotating disk 31. When the cabinet door of the installing cabinet 20 is closed, the cabinet door will push the supporting spring 41 to move it backward, and the supporting spring 41 sleeved on the top rod 42 will also be compressed. The moving rod 39 fixed on the rear end of the fixing block 40 will abut against the protrusion 38, thereby pushing the connecting plate 37 so that the multiple groups of card blocks 34 fixed on the connecting plate 37 remain engaged with the card slots 33, and are fixed on the left side of the connecting plate 37. The two groups of first springs 35 will be in a stretched state. At this time, the engagement and fixation between the card slot 33 and the card block 34 can be used to prevent the rotating disk 31 from rotating, thereby ensuring that the device body 1 inside the installation cabinet 20 will not move due to external vibrations. When the cabinet door of the installation cabinet 20 is opened again, under the action of the support spring 41, the push rod 42 will move forward. After the protrusion 38 is no longer in contact with the moving rod 39, the first spring 35 will pull the connecting plate 37, and the card block 34 fixed on the connecting plate 37 will be separated from the card slot 33. At this time, the rotating disk 31 can be rotated normally. At the same time, when the cabinet door of the installation cabinet 20 is opened, the push rod 42 can be pushed to fix the rotating disk 31, so as to prevent the device body 1 from moving forward during maintenance and overhaul.

[0037] Through the structural design of the locking mechanism, when the mobile platform 22 moves forward, the triangular block 46 fixed on the long plate 45 will abut against the mobile plate 47 and push the mobile plate 47 to move to both sides, and the shape design of the triangular block 46 and the mobile plate 47 makes it impossible for the long plate 45 to move backward, so that during the maintenance and inspection process, it will not move backward due to hitting the device body 1 or the mobile platform 22. After the cabinet door of the installation cabinet 20 is opened, under the action of the two groups of fixed springs 54, the top block 51 will move inside the moving groove 56 and no longer abut against the two groups of sliding blocks 53. At this time, under the action of multiple groups of second springs 49 fixed on the mobile plate 47 , the two sets of sliding blocks 53 will gradually approach each other, and the moving plate 47 will also engage with the triangular block 46. At this time, when the device body 1 is moved out of the installation cabinet 20, the long plate 45 fixed on the bottom end of the moving platform 22 will abut against the moving plate 47 and push the moving plate 47 to move to both sides. Due to the shape design of the triangular block 46 and the moving plate 47, the long plate 45 can only move forward. When moving backward, the triangular block 46 will abut against the moving plate 47 to ensure that the device body 1 can only move forward, so as to avoid accidentally touching the device body 1 during maintenance and overhaul, causing it to move toward the inside of the installation cabinet 20, resulting in the need to pull the device body 1 out of the installation cabinet 20 again.

[0038] Furthermore, an annular groove 57 is formed at the bottom end of the rotating disk 31, and a plurality of supporting wheels 58 are welded and fixed to the inner wall of the annular groove 57;

[0039] During operation, an annular groove 57 is opened on the bottom end of the rotating disk 31. Through multiple sets of supporting wheels 58 fixed on the annular groove 57, when the rotating disk 31 is pushed to rotate, the bottom end of the rotating disk 31 can be supported by the supporting wheels 58, so that the rotating disk 31 can be more stable during the rotation process and is not prone to shaking.

[0040] Furthermore, an abutment block 59 is welded and fixed to the front end of the rotating disk 31, and the right side of the abutment block 59 abuts against a stopper 60, and the stopper 60 is welded and fixed to the inner wall of the notch 32;

[0041] During operation, the abutment between the abutment block 59 and the stopper 60 ensures that the rotating disk 31 can only be rotated in the clockwise direction, thereby ensuring that the rack 28 can move normally inside the long slot 64 .

[0042] Furthermore, pads 63 are welded and fixed on both the front and rear sides of the inner wall of the long groove 64. The pads 63 are made of rubber. The rear end pads 63 are in contact with the rear end of the rack 28.

[0043] During operation, the pad block 63 is designed to buffer the front and rear sides of the rack 28 and the inner wall of the long slot 64 to ensure that the rack 28 does not abut against the inner wall of the long slot 64 when the rack 28 moves to the maximum distance, thereby reducing the wear of the rack 28.

[0044] Furthermore, a rectangular groove 61 is provided in the middle of the front end of the support base 21, and the size of the rectangular groove 61 is the same as that of the card slot 33;

[0045] During operation, a rectangular groove 61 is opened in the middle position of the front end of the support base 21, and the size of the rectangular groove 61 is the same as the card slot 33, so that the rotation angle of the rotating disk 31 can be adjusted by aligning the card slot 33 on the rotating disk 31 with the rectangular groove 61 to ensure that the card block 34 can be correctly engaged with the card slot 33.

[0046] Furthermore, the rear end of the fixing block 40 abuts against the inner wall of the cavity 44, and both the fixing block 40 and the cavity 44 are rectangular in design;

[0047] During operation, the fixed block 40 and the cavity 44 are both rectangular in design, and the rear end of the fixed block 40 abuts against the inner wall of the cavity 44, so as to ensure that when the push rod 42 is pushed to the maximum distance, the moving rod 39 can contact and abut against the protrusion 38. At this time, when the push rod 42 is pushed, the fixed block 40 will abut against the inner wall of the cavity 44.

[0048] Furthermore, a sealing strip 62 is glued and fixed to the bottom end of the movable platform 22, and the sealing strip 62 contacts the inner wall of the groove 25;

[0049] During operation, the sealing strip 62 is made of rubber material. The sealing strip 62 is in contact with the groove 25 to improve the sealing between the bottom end of the mobile platform 22 and the groove 25 , so as to reduce the adhesion of external dust on the bottom end of the mobile platform 22 .

[0050] Working principle: The magnetic levitation flywheel energy storage device in the prior art needs regular maintenance to ensure that the device can operate stably and efficiently for a long time. Since the magnetic levitation flywheel energy storage device is fixedly installed inside the installation cabinet and will occupy a large space, and the space inside the installation cabinet itself is relatively limited, it will be inconvenient during maintenance and inspection. A magnetic levitation flywheel energy storage device in this case realizes the function of facilitating the removal of the mobile platform 22 together with the entire device body 1 from the inside of the installation cabinet 20 through the structural design of the removal mechanism, so as to free up a larger space for maintenance and inspection of the device body 1. When the device body 1 is to be maintained and inspected, first, after the cabinet door of the installation cabinet 20 is opened, since the front end of the top rod 42 is no longer abutted against the cabinet door, the fixing mechanism will release the fixation of the rotating disk 31, and the rotating disk 31 can rotate normally. A slot 32 is provided at the front end of the support base 21. The slot 32 is used to facilitate the rotation of the rotating disk 31 inside the support base 21. The rotating disk 31 is rotated clockwise to drive the gear 29 on the rotating shaft 30 to rotate. The gear 29 is meshed with the rack 28, so the rack 28 will move inside the long slot 64. As the rack 28 continues to move forward, the long block 26 connected to the rack 28 can drive the mobile platform 22 to slide on the groove 25, thereby moving the device body 1 fixed on the mobile platform 22 out of the installation cabinet 20, so as to facilitate the maintenance and inspection of the device body 1. In order to ensure the stable movement of the mobile platform 22 during the sliding process, sliders 23 are fixed on both sides of the mobile platform 22. The sliders 23 will abut against the inner wall of the slide groove 24 to support the mobile platform 22, reduce the pressure that the long block 26 and the rack 28 need to bear, and also limit the movement of the mobile platform 22 in the left and right directions.

[0051] Through the structural design of the fixing mechanism, when the cabinet door 20 is installed, the multiple groups of card blocks 34 fixed on the connecting plate 37 can fix the rotating disk 31 by engaging with the card slots 33, ensuring that the rotating disk 31 does not rotate, and when the cabinet door of the installing cabinet 20 is opened, the engagement between the card blocks 34 and the card slots 33 is released to facilitate the normal rotation of the rotating disk 31. When the cabinet door of the installing cabinet 20 is closed, the cabinet door will push the supporting spring 41 to move it backward, and the supporting spring 41 sleeved on the top rod 42 will also be compressed. The moving rod 39 fixed on the rear end of the fixing block 40 will abut against the protrusion 38, thereby pushing the connecting plate 37 so that the multiple groups of card blocks 34 fixed on the connecting plate 37 remain engaged with the card slots 33, and are fixed on the left side of the connecting plate 37. The two groups of first springs 35 will be in a stretched state. At this time, the engagement and fixation between the card slot 33 and the card block 34 can be used to prevent the rotating disk 31 from rotating, thereby ensuring that the device body 1 inside the installation cabinet 20 will not move due to external vibrations. When the cabinet door of the installation cabinet 20 is opened again, under the action of the support spring 41, the push rod 42 will move forward. After the protrusion 38 is no longer in contact with the moving rod 39, the first spring 35 will pull the connecting plate 37, and the card block 34 fixed on the connecting plate 37 will be separated from the card slot 33. At this time, the rotating disk 31 can be rotated normally. At the same time, when the cabinet door of the installation cabinet 20 is opened, the push rod 42 can be pushed to fix the rotating disk 31, so as to prevent the device body 1 from moving forward during maintenance and overhaul.

[0052] Through the structural design of the locking mechanism, when the mobile platform 22 moves forward, the triangular block 46 fixed on the long plate 45 will abut against the mobile plate 47 and push the mobile plate 47 to move to both sides, and the shape design of the triangular block 46 and the mobile plate 47 makes it impossible for the long plate 45 to move backward, so that during the maintenance and inspection process, it will not move backward due to hitting the device body 1 or the mobile platform 22. After the cabinet door of the installation cabinet 20 is opened, under the action of the two groups of fixed springs 54, the top block 51 will move inside the moving groove 56 and no longer abut against the two groups of sliding blocks 53. At this time, under the action of multiple groups of second springs 49 fixed on the mobile plate 47 , the two sets of sliding blocks 53 will gradually approach each other, and the moving plate 47 will also engage with the triangular block 46. At this time, when the device body 1 is moved out of the installation cabinet 20, the long plate 45 fixed on the bottom end of the moving platform 22 will abut against the moving plate 47 and push the moving plate 47 to move to both sides. Due to the shape design of the triangular block 46 and the moving plate 47, the long plate 45 can only move forward. When moving backward, the triangular block 46 will abut against the moving plate 47 to ensure that the device body 1 can only move forward, so as to avoid accidentally touching the device body 1 during maintenance and overhaul, causing it to move toward the inside of the installation cabinet 20, resulting in the need to pull the device body 1 out of the installation cabinet 20 again.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
