[0001] The invention relates to the technical field of transformers, in particular to a dual-voltage anti-theft transformer. Background Art

[0002] my country is a large electricity consumer. Many communities have high electricity consumption. It is not enough to rely solely on cable transmission of electricity. Transformers are often needed for regulation. It is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil and iron core. According to their uses, they can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, corner transformers, etc.

[0003] There are a lot of copper wires inside the existing transformer. Criminals turn off the power supply, use tools to cut the wires, push the transformer down, and easily transport or disassemble the transformer to take out the copper wires inside. During the operation of the transformer, the internal space is sealed and long-term operation causes the internal temperature to rise, which can easily cause the transformer to overload and burn. On rainy days, rainwater will flow into the gaps of the transformer, and water contacting the transformer is likely to cause leakage, which poses a great safety hazard. During the installation of the transformer, the fixing device at the bottom has a simple structure and is easily dismantled by criminals. For this reason, the present invention provides a dual-voltage anti-theft transformer. Summary of the invention

[0024] See also Figure 1-6 A dual-voltage anti-theft transformer comprises a shell 1, a box door 5 is arranged on the side of the shell 1, and the box door 5 is clamped to the side of the shell 1. Opening the box door 5 facilitates the maintenance of the transformer equipment 21 in the shell 1, and enhances the sealing effect. A hoop groove 7 is arranged on the side of the box door 5, and a fixing block 6 is clamped inside the hoop groove 7. The fixing block 6 is inside the hoop groove 7 of the box door 5, which can enhance the clamping effect and make the box door 5 more closed. Connecting columns 10 are fixedly connected on both sides of the fixing block 6, and clamping devices 9 and locking devices 11 are fixedly connected on both sides of the connecting column 10. A heat dissipation device 15 is fixedly installed on one side of the shell 1, and a rainproof device 8 is arranged on the top of the shell 1.

[0025] Among them, the clamping device 9 includes a wall groove 29, a lock core 30 and a fixed block 31. The connecting column 10 is movably sleeved with a crossbeam 28. The crossbeam 28 forms a connection relationship with the connecting columns 10 on both sides, so that the shell 1 and the door 5 are connected together to prevent them from being opened by criminals. A wall groove 29 is opened on the side of the connecting column 10, and a lock core 30 is arranged inside the crossbeam 28. A fixed block 31 is fixedly installed on the other side of the lock core 30. Inserting the key to rotate the lock core 30 rotates the fixed block 31 at the bottom of the lock core 30, and the rotating fixed block 31 is clamped with the connecting column 10 on the left side. Only a specific key can rotate the lock core 30, thereby enhancing the anti-theft effect.

[0026] Among them, the connecting column 10 includes a clamping block 25, an extension block 26 and an inner groove 27. The inner groove 27 is opened inside the connecting column 10, and a cross beam 28 is clamped inside the inner groove 27. Both sides of the cross beam 28 are fixedly connected with extension blocks 26, and one side of the extension block 26 is fixedly connected with a clamping block 25. When the clamping blocks 25 on the extension blocks 26 on both sides of the cross beam 28 touch the connecting column 10, the clamping block 25 and the connecting column 10 form a clamping relationship to increase the fastening force.

[0027] Among them, the heat dissipation device 15 includes a heat dissipation device shell 12, a motor 13, an electric wire 14, a main fan blade 19 and an auxiliary fan blade 20. The side of the heat dissipation device shell 12 is fixedly connected to the outer shell 1, and the other side of the heat dissipation device shell 12 is fixedly installed with the motor 13. The bottom of the motor 13 is fixedly connected with the electric wire 14. The electric wire 14 provides power to the motor 13 to ensure the efficiency of the motor 13 and prevent the output power from affecting the heat dissipation effect. The main fan blade 19 is fixedly installed on the side of the motor 13, and the auxiliary fan blade 20 is arranged on one side of the inner wall of the heat dissipation device shell 12. The motor 13 drives the main fan blade 19 to rotate to generate strong wind force, and the wind drives the auxiliary fan blade 20 on the side to rotate, thereby enhancing the wind force and saving energy.

[0028] Among them, a heat dissipation layer 18 is fixedly installed on the top of the shell 1, and the cooled hot air is discharged from the heat dissipation layer 18 on the top of the shell 1. At the same time, the heat dissipation layer 18 is not sealed, and the outside temperature can enter the shell 1 for cooling again, thereby enhancing the cooling effect. A rainproof device 8 is arranged on the top of the heat dissipation layer 18, and the rainproof device 8 includes a screw groove 16, a fixing nut 17, a first rain shield 22, a second rain shield 23 and a vertical plate 24.

The first rain shield 22 and the second rain shield 23 are in an inclined state, which can directly slide rainwater off, avoid rainwater from entering, and enhance the waterproof effect. A screw groove 16 is opened on the top of the first rain shield 22 and the second rain shield 23, and a fixing nut 17 is arranged inside the screw groove 16.

[0029] Among them, a transformer device 21 is arranged inside the shell 1, a connecting block 2 is fixedly connected to the bottom of the shell 1, a fixed guardrail 3 is movably sleeved on the bottom of the connecting block 2, the fixed guardrail 3 limits and fixes the connecting block 2, and strengthens the fixing effect, so that criminals cannot directly push down the transformer by hand, and the bottom of the fixed guardrail 3 is fixedly connected to the bottom of the base plate 4.

[0030] Working principle: During use, the user inserts the fixing block 6 into the hoop groove 7 of the door 5 during installation, and the connecting columns 10 on both sides of the fixing block 6 fix the two sides of the outer shell 1. The crossbeam 28 passes through the inner groove 27 opened by the right connecting column 10. When the blocks 25 on the extension plates on both sides of the connecting column 10 touch the connecting column 10, they stop moving to form a lock claw connection. The crossbeam 28 then passes through the inner groove 27 of the connecting column 10 on the left side, insert the key and turn the lock cylinder 30, so that the fixing block 31 at the bottom of the lock cylinder 30 rotates, and the rotating fixing block 31 forms a connection with the connecting column 10 on the left side, thereby locking the outer shell 1 and the door 5. When the transformer equipment 21 works for a long time, the internal temperature continues to rise. The wire 14 provides power to the motor 13, and the motor 13 drives the main fan on the side to rotate. The strong wind drives the auxiliary fan on the side to rotate together to cool the transformer equipment 21. The cooled hot air is discharged from the heat dissipation layer 18 on the top of the shell 1, and the outside temperature can also enter the shell 1 through the heat dissipation layer 18 to cool down. On rainy days, rainwater directly slides down from the surface of the first rain shield 22 and the second rain shield 23 of the rainproof device 8, and will not enter the inside of the shell 1 to cause leakage of the transformer equipment 21. A connecting block 2 is fixedly connected to the bottom of the shell 1, and a fixed guardrail 3 is installed around the connecting block 2. Then the fixed guardrail 3 and the bottom plate 4 are fixedly connected, so that the shell 1 and the bottom plate 4 are tightly connected.
