DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] See also Figure 1-Figure 6 As shown, a modular building block type SVG power device comprises:

[0032] Insulation board 1;

[0033] A lifting structure 2 is provided at the bottom end of the insulating plate 1, a bottom frame 3 is provided at the top end of the insulating plate 1, a plurality of base structures 4 are installed at equal distances at the top end of the bottom frame 3, a plurality of power unit modules 5 and a plurality of backup capacitor modules 6 are installed at the top ends of the front and rear base structures 4, a fan module 7 is installed at the top ends of the power unit modules 5 and the backup capacitor modules 6, and a plurality of universal wheels 8 are installed at equal distances at the bottom end of the lifting structure 2;

[0034] The base structure 4 includes a fixed frame 41, a positioning structure 42, an insertion plate 43 and a connecting plate 44. There are four positioning structures 42, and the four positioning structures 42 are installed at the four corners of the top of the fixed frame 41. The insertion plate 43 is movably inserted and connected in the four positioning structures 42. The connecting plate 44 is fixedly connected to the top of the insertion plate 43. The fixed frame 41 is installed at the top of the base frame 3.

[0035] Depend on Figure 5 and Figure 6It can be seen that the positioning structure 42 includes a fixed block 421, a second limiting groove 422, a through-slot 423, an insertion block 424, a fixed frame 425 and a positioning rod 426. The second limiting groove 422 is arranged at one end of the fixed block 421. There are two through-slots 423 and two insertion blocks 424, and the two through-slots 423 are arranged on both sides of the top of the fixed block 421. The two insertion blocks 424 are movably inserted and connected in the two through-slots 423 respectively. The fixed frame 425 is installed at one end of the fixed block 421. The positioning rod 426 is threadedly connected in the fixed frame 425. The end of the positioning rod 426 away from the fixed frame 425 passes through the fixed block 421 and is tightly attached to one end of the insertion block 424. The fixed block 421 is installed at the top of the base frame 3.

[0036] As can be seen from the above, first, the power unit module 5 and the backup capacitor module 6 are installed. The two modules at the bottom have been fixedly connected to the connecting plate 44 in advance. Then, the insertion plate 43 is inserted into the four second limit slots 422 on the base structure 4. In this process, the insertion blocks 424 on the insertion plate 43 will enter the insertion slots 423 one by one. Next, we rotate the positioning rod 426 to make it rotate and move backward in the fixing frame 425. This action prompts the positioning rod 426 to move smoothly to the inside of the fixing block 421 and fit tightly to one end of the insertion block 424. Through such a design, the insertion block 424 is firmly fixed, thereby ensuring the stability and firmness of the bottom power unit module 5 and the backup capacitor module 6 in the base structure 4. The completion of this step lays a solid foundation for the stable operation of the entire device.

[0037] Preferably, the insertion plate 43 is movably inserted and connected in the second limiting groove 422 , and the connecting plate 44 is fixedly connected to the top of the insertion block 424 .

[0038] As can be seen from the above, the insertion plate 43 is inserted into the second limiting groove 422 , so that the insertion plate 43 can be limited by the second limiting groove 422 .

[0039] Embodiment 2:

[0040] refer to Figure 2 and Figure 3 As shown, the lifting structure 2 includes a connecting seat 21, an adjusting structure 22, a supporting rod 24 and a base 25. The adjusting structure 22 is installed on the surface of the connecting seat 21. The four corners of the connecting seat 21 are provided with first limiting grooves 23. The first limiting grooves 23 are movably installed with supporting structures 26. The base 25 is arranged at the bottom end of the connecting seat 21. Two supporting rods 24 are provided, and the two supporting rods 24 are respectively fixedly connected to the middle of the two ends of the adjusting structure 22. The connecting seat 21 is arranged at the bottom end of the insulating plate 1;

[0041] The adjustment structure 22 includes a connecting frame 221, a belt 223, a driving wheel 225 and a driver 226. There are two connecting frames 221, and rotating wheels 222 are movably installed on both sides of the two connecting frames 221. The belts 223 are sleeved on the outer surfaces of the four rotating wheels 222. Two mounting plates 224 are provided at the top and bottom ends of the connecting frame 221. The driving wheel 225 is arranged on one side of the belt 223. The driver 226 is installed in the middle of the bottom end of the driving wheel 225. The connecting frames 221 are installed on the surface of the connecting seat 21.

[0042] As can be seen from the above, the device can be easily moved in different locations by relying on the flexibility of the universal wheel 8. When the device is moved to the predetermined installation position, the driver 226 is immediately started. Once the driver 226 is started, it drives the driving wheel 225 firmly connected to it to start rotating. The rotating driving wheel 225 further drives the belt 223 tightly connected to it to move. The displacement of the belt 223 drives the rotating wheel 222 connected to it to rotate. This series of transmission processes ultimately effectively drives the support structure 26 to perform lifting operations through the rotation of the rotating wheel 222. This design enables the device to flexibly adjust its height according to the actual needs of movement or installation, greatly improving the applicability and operational flexibility of the device.

[0043] Preferably, the base 25 is installed together with a plurality of universal wheels 8;

[0044] The driver 226 is mounted on one end of the connecting base 21 , and the mounting plate 224 is mounted on one end of the connecting base 21 .

[0045] As can be seen from the above, the universal wheel 8 is used to facilitate the movement of the device, and the driver 226 is installed at one end of the connecting seat 21, so that the connecting seat 21 can support the driver 226.

[0046] Embodiment three:

[0047] refer to Figure 4 As shown, the support structure 26 includes a screw 261, a displacement block 262, a connecting rod 263 and a base plate 264. The displacement block 262 is threadedly connected to the outer surface of the screw 261. Two connecting rods 263 are provided, and the two connecting rods 263 are installed at both ends of the displacement block 262. The base plate 264 is installed at the bottom ends of the two base plates 264. The bottom end of the screw 261 is movably installed at the bottom end of the inner groove wall of the first limiting groove 23.

[0048] As can be seen from the above, when the rotating wheel 222 starts to rotate, it effectively drives the screw 261 to rotate synchronously. This rotation action in turn causes the displacement block 262 to slowly move downward along the outer surface of the screw 261. As the displacement block 262 moves downward, it is tightly connected to and drives the connecting rod 263 to move downward together. The connecting rod 263, as a key component for transmitting force in the middle, continues to transmit this downward movement to the base plate 264, so that the base plate 264 can move downward smoothly and firmly until it fits tightly with the ground. This design cleverly ensures that the device can be firmly fixed in place during use, effectively preventing the device from being displaced due to external factors, thereby greatly improving the stability and safety of the device.

[0049] Preferably, the top end of the screw rod 261 is fixedly connected to the bottom end of the rotating wheel 222;

[0050] The displacement block 262 is movably inserted into the first limiting groove 23 .

[0051] As can be seen from the above, the screw 261 is fixedly connected to the rotating wheel 222, so that when the rotating wheel 222 rotates, it can drive the screw 261 to rotate, thereby adjusting the height of the displacement block 262, and the displacement block 262 is movably inserted into the first limiting groove 23, so that the first limiting groove 23 can be used to limit the displacement block 262.

[0052] Furthermore, the design of the present invention is applied in the assembly of SVG power device. First, we install the power unit module 5 and the backup capacitor module 6. The two bottom modules have been pre-fixed firmly with the connecting plate 44. Then, the insertion plate 43 is inserted into the four second limit slots 422 on the base structure 4. In this process, the insertion blocks 424 closely connected to the fixed frame 41 will enter the corresponding insertion slots 423 one by one. Then, we gently rotate the positioning rod 426 to make it rotate smoothly in the fixing frame 425 and produce backward displacement until the positioning rod 426 is firmly embedded in the fixing block 421 and fits tightly with one end of the insertion block 424, thereby effectively fixing the insertion block 424. In this way, the bottom power unit module 5 and the backup capacitor module 6 are firmly fixed in the base structure 4, which significantly improves the stability of the bottom of the device.

[0053] Next, in the same manner, the remaining power unit modules 5 and backup capacitor modules 6 are stacked in sequence to ensure that the structure of the entire device is complete and stable.

[0054] When the device is assembled, the device is pushed, and the flexibility of the universal wheel 8 is utilized to enable the device to be freely moved between different locations. When the device is moved to the predetermined installation position, the driver 226 is started, and the driver 226 immediately drives the driving wheel 225 closely connected thereto to start rotating. The rotating driving wheel 225 further drives the belt 223 sleeved therewith to move. The displacement of the belt 223 drives the rotating wheel 222 sleeved therewith to rotate accordingly. The rotation of the rotating wheel 222 finally drives the screw 261 fixedly connected thereto to rotate. As the screw 261 rotates, the displacement block 262 closely connected to it begins to move slowly downward on the outer surface of the screw 221. This movement process drives the connecting rod 263 installed with the displacement block 262 to move downward together. Finally, the downward movement of the connecting rod 263 pushes the base plate 264 fixedly connected to it to move steadily downward until it fits tightly with the ground. This design not only ensures that the device can be firmly fixed in place during use, but also effectively prevents the displacement of the device due to external factors, thereby greatly improving the overall stability and safety of the device.
