[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] See also Figures 1-7, the present invention: a transformer anti-theft structure, including two support rods 1, the two support rods 1 are fixedly connected to a base 2, the top of the base 2 is installed with a transformer body 3, the top of the base 2 is fixedly connected to a vertical plate 4, the base 2 is slidably connected to a protection box 5, the inner side of the protection box 5 is in contact with the vertical plate 4, the base 2 is interspersed with two screw rods 6 rotatably connected to it, a driving mechanism 7 is provided on the base 2, the tops of the two screw rods 6 are connected to the driving mechanism 7, a lifting plate 8 is provided below the protection box 5, the top of the lifting plate 8 is fixedly connected to two groups of connecting rods 9 arranged at equal distances, the tops of the two groups of connecting rods 9 are fixedly connected to the protection box 5, the lifting plate 8 are respectively sleeved on two support rods 1 and two screw rods 6, the outer sides of the two screw rods 6 are threadedly connected to the lifting plate 8, the top of the lifting plate 8 is fixedly connected to the mounting plate 10, and the front of the mounting plate 10 is installed with a facial recognition module 11, a password recognition module 12 and a controller 13; the driving mechanism 7 includes a motor 701, the bottom of the motor 701 is fixedly connected to the base 2, and a driving wheel 702 rotatably connected to the bottom of the base 2 is inserted, and the top of the driving wheel 702 is fixedly connected to the output shaft of the motor 701, and the two screw rods 6 are sleeved with a passive wheel 703 fixedly connected to them, and the outer sides of the two passive wheels 703 are meshed with the driving wheel 702.

[0035] In the present invention, when in use, a closed box can be formed between the protective box 5, the vertical plate 4 and the base 2 to enclose the transformer body 3. The box thus formed can play a role in physical protection of the transformer body 3. When the transformer body 3 needs to be maintained, the worker first stands on the top of the lifting plate 8, and then faces the facial recognition module 11. The facial recognition module 11 will recognize the worker's face. After the facial recognition is passed, the worker can operate the controller 13 to start the motor 701 to drive the driving wheel 702 to rotate. The driving wheel 702 is engaged with the passive wheel 703, so the passive wheel 703 will rotate, and then the two screw rods 6 will rotate. The screw rod 6 is threadedly connected to the lifting plate 8, thereby driving the lifting plate 8 to rise along the support rod 1. During the rising process of the lifting plate 8, the worker and the protective box 5 will be driven to move up, and the protective box 5 rises, the transformer body 3 will be exposed until the protection box 5 is higher than the transformer body 3. At this time, the worker will be driven to the side of the transformer body 3, which makes it convenient for the worker to maintain the transformer body 3. After the maintenance of the transformer body 3 is completed, the user drives the motor 701 in reverse through the controller 13 to drive the lifting plate 8 to descend until the lifting plate 8 returns to its original position. At this time, the controller 13 will return to the locked state; if the worker fails to pass the recognition of the facial recognition module 11, the controller 13 will not be able to control the start of the motor 701. The worker can also enter a specified password through the password recognition module 12 to authenticate the controller 13. If the password is wrong, the motor 701 cannot be controlled. If the motor 701 cannot be controlled to open and close, the lifting and lowering of the protection box 5 cannot be controlled, and the anti-theft effect can be achieved.

[0036] See also Figure 5 , wherein: two mounting grooves 14 are provided on the base 2, and the inner walls of the two mounting grooves 14 are interspersed with locking rods 15 slidably connected thereto, and the two locking rods 15 are sleeved with airbag rings 16 slidably connected thereto, and the top and bottom of the two airbag rings 16 are fixedly connected to the two mounting grooves 14 respectively, and the top of the driving wheel 702 is provided with two lock holes 17 adapted to the locking rods 15, and the inner walls of the two lock holes 17 are installed with electromagnets 18, and the input ends of the two electromagnets 18 are connected to the controller 13 signal; the bottom of the driving wheel 702 is fixedly connected with a square rod 19, and the square rod 19 is square in shape. The bottom end of the square rod 19 is inserted into the lifting plate 8 and slidably connected thereto, and a driving sleeve 20 slidably connected thereto is sleeved on the square rod 19, and the bottom of the driving sleeve 20 is rotatably connected to the lifting plate 8.

[0037] In the application, in the state of the controller 13 being locked, the controller 13 will start two electromagnets 18, the electromagnets 18 will generate magnetic force when powered on, the magnetic force will attract the bottom end of the lock rod 15, the lock rod 15 will be inserted into the lock hole 17 on the driving wheel 702, and the cooperation of the lock rod 15 and the lock hole 17 can realize the locking of the driving wheel 702, at this time, even if the two lead screws 6 can be rotated at the same time, the driving wheel 702 will also lock the lead screws 6, thereby improving the anti-theft effect of the transformer body 3.

[0038] After the worker identity authentication is successful, the controller 13 will turn off the electromagnet 18, at this time, the lock rod 15 will lose the magnetic attraction effect, the air bag ring 16 will drive the lock rod 15 to rise and separate from the lock hole 17, thereby realizing the unlocking of the driving wheel 702, and the driving wheel 702 can be rotated by the motor 701 to complete the lifting of the protection box 5.

[0039] If a power failure occurs, the motor 701 cannot be started, the electromagnet 18 will be powered off, and the lock rod 15 will be pulled out of the lock hole 17, thereby realizing the automatic unlocking effect of the driving wheel 702, at this time, the user can rotate the driving sleeve 20 to drive the square rod 19 to rotate, and the square rod 19 will drive the driving wheel 702 to rotate, thereby driving the two lead screws 6 to rotate at the same time, thereby driving the lifting plate 8 and the protection box 5 to rise, thereby realizing the effect of maintaining the transformer body 3 in the case of power failure.

[0045] In the present invention, the threading hole 25 is provided for the entry and exit of the lines used in the transformer body 3. During the descent of the protective box 5, the protective box 5 will squeeze the round rod 29 to drive the piston plate 28 to descend along the inner wall of the cavity 27. During the process, the air inside the cavity 27 will be pressed into the transverse cavity 31 through the conduit, and the air will then enter the airbag 26 from the air inlet pipe 32. The airbag 26 will then expand. After the airbag 26 expands, it will be in close contact with the lines of the transformer body 3, thereby effectively preventing dust from entering the protective box 5 from the threading hole 25 and causing pollution to the transformer body 3. In addition, the airbag 26 can buffer the space between the lines and the threading hole 25, reduce the wear of the lines, and improve the safety of the device.
