As a device that uses the principle of electromagnetic induction to change the AC voltage, it is used in many scenarios such as industry. It is widely used in industry, agriculture, transportation, urban communities and other fields. According to its use, it can be divided into: power transformers and special transformers.

[0003] The utility model patent with announcement number CN213988564U discloses a transformer with leakage alarm function, including a transformer body, a leakage monitoring sensor is fixedly embedded in the side wall of the transformer body, a bracket located on one side of the leakage monitoring sensor is fixedly connected to one side of the transformer body, a real-time display screen is installed in the bracket, and a protective shell covering the leakage monitoring sensor and the real-time display screen is fixedly connected to one side of the transformer body, a wireless signal transceiver is fixedly inserted in the upper end of the protective shell, an audible and visual alarm is fixedly inserted in the lower end side wall of the protective shell, and a tempered glass protective plate is fixedly connected to the side of the protective shell away from the transformer body. The body in the above application document has a good leakage alarm function, making it safer to use, but there is a lack of power-off processing for the transformer after the early warning, so that the transformer with leakage risk is still in use, which may cause harm to the surrounding. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a transformer with a leakage alarm function, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a transformer with a leakage alarm function, including a transformer and an output wire, a wire is fixedly installed on the side of the transformer and is electrically connected to the wire, another wire is fixedly connected to one end of the output wire close to the transformer, a mounting shell is fixedly installed on the side of the transformer, a sliding groove is provided on the side of the mounting shell, a leakage detector is fixedly installed on the side of the mounting shell, a card connector is fixedly installed inside the leakage detector, an electromagnet is fixedly installed on the side of the mounting shell, the electromagnet is electrically connected to the leakage detector, an indicator light is fixedly installed on the top of the mounting shell, and the indicator light is electrically connected to the leakage detector, The inner wall of the sliding groove is slidably connected to a mounting seat, a knob is rotatably connected to the side of the mounting seat, an elliptical block is fixedly installed on the bottom side of the knob, two support arms are fixedly installed on the side of the mounting seat, an arc-shaped sliding pad is fixedly installed on the middle of the sides of the two support arms, the insides of the two support arms are elastically connected with L-shaped rods through springs, the two support arms are slidably connected to clamps on the opposite sides, a sliding column is fixedly installed on the side of the mounting seat close to the clamp, the sliding column is slidably connected to the clamp, sliders are slidably connected on both sides of the clamp, a clamping block is fixedly installed on the side of the slider close to the L-shaped rod, the wires are located inside the clamp, and the two wires are located inside the leakage detector and are clamped through a clamping connector.

[0005] Preferably, a spring is wound around the outside of the sliding column and is located between the clamp and the mounting seat. The two wires are electrically connected when they are clamped by the card connector. When the wires are detached from the card connector, the power is cut off, and the output wires are de-energized.

[0006] Preferably, there are two clamps and they are symmetrically arranged on both sides of the arc-shaped sliding pad. The top sides of the two clamps are threadedly connected with a threaded rotating rod. The side of the threaded rotating rod away from the clamp is rotatably connected to a steering plate. The steering plate is rotatably connected to a roller. The roller contacts the side of the wire to further clamp the wire so that the wire can be driven by the clamp.

[0007] Preferably, the clamp is arranged in an arc-shaped structure, and the roller and the threaded rotating rod are both made of plastic insulating material to avoid the risk of electrical conduction during contact with the wires.

[0008] Preferably, a fixing column is fixedly installed on one side of the inner wall of the sliding groove, and a clamping groove is slidably connected to the upper side of the fixing column.

[0009] Preferably, a spring is wrapped around the outside of the fixed column, the surface of the ball is made of rough material, and the snap-in groove is slidably connected to the inner wall of the sliding groove. Because there is a large friction between the ball and the snap-in groove, it can slow down the movement speed during rotation and provide a certain resistance to the sliding of the mounting seat.

[0010] The utility model provides a transformer with a leakage alarm function, which has the following beneficial effects:

[0011] (1) The utility model uses the cooperation between the clamp and the knob to enable the clamp to move up and down in the support arm, so as to clamp wires of different specifications and prevent the clamp and the wires from slipping. When the leakage detector detects leakage of the wire, the indicator light comes on and the mounting seat slides along the sliding groove toward the electromagnet, so that the wire and the card connector are separated and the transformer stops supplying power, thereby ensuring the safety and stability of the transformer.

[0012] (2) The utility model drives the steering plate and the roller to approach the position of the electric wire through the threaded rotating rod, so that the roller clamps the side of the electric wire. The rolling friction of the roller on the side of the electric wire enables the electric wire to be further stably clamped to prevent the mounting base from being separated from the electric wire when the mounting base moves, and can cooperate with the leakage detector to realize timely power off.

[0013] (3) The utility model drives the ball bearing to rotate in the clamping groove through the mounting seat. The ball bearing can slow down the movement speed when rotating, and provide a certain resistance to the sliding of the mounting seat. When the transformer is hit, the collision force will be weakened by the spring on the outside of the fixing column, thereby reducing the impact on the mounting seat and avoiding affecting the normal operation of the wires.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-3A transformer with a leakage alarm function comprises a transformer 1 and an output wire 3. A wire 2 is fixedly installed on the side of the transformer 1 and is electrically connected to the wire 2. One end of the output wire 3 close to the transformer 1 is fixedly connected to another wire 2. A mounting shell 4 is fixedly installed on the side of the transformer 1. A sliding groove 5 is provided on the side of the mounting shell 4. A leakage detector 7 is fixedly installed on the side of the mounting shell 4. A card connector 9 is fixedly installed inside the leakage detector 7. An electromagnet 11 is fixedly installed on the side of the mounting shell 4. The electromagnet 11 is electrically connected to the leakage detector 7. An indicator light 10 is fixedly installed on the top of the mounting shell 4. The indicator light 10 is electrically connected to the leakage detector 7. A mounting seat 6 is slidably connected to the inner wall of the sliding groove 5. A knob 16 is rotatably connected to the side of the mounting seat 6. An elliptical block 17 is fixedly installed on the bottom side of the knob 16. Two support arms 8 are fixedly installed on the side of the mounting seat 6. An arc-shaped sliding pad 12 is fixedly installed in the middle of the side of the two support arms 8. The insides of the two support arms 8 are elastically connected to L-shaped rods 15 through springs. The two support arms 8 are slidably connected to the opposite sides of the clamp 1 3. A sliding column 18 is fixedly installed on one side of the mounting seat 6 close to the clamp 13. The sliding column 18 is slidably connected to the clamp 13. Slide blocks 19 are slidably connected to both sides of the clamp 13. A clamping block 20 is fixedly installed on one side of the slider 19 close to the L-shaped rod 15. The wire 2 is located inside the clamp 13. The two wires 2 are located inside the leakage detector 7 and are clamped by the clamping joint 9. A spring is wound around the outside of the sliding column 18 and is located between the clamp 13 and the mounting seat 6. When the two wires 2 are clamped by the clamping joint 9, they are electrically connected. 2 is disconnected from the card connector 9, and the output wire 3 is powered off at this time. The utility model cooperates with the clamp 13 and the knob 16 to enable the clamp 13 to move up and down in the support arm 8, so as to clamp the wires 2 of different specifications and prevent the clamp 13 and the wire 2 from slipping. When the leakage detector 7 detects that the wire 2 is leaking, the indicator light 10 lights up, and the mounting seat 6 slides along the sliding groove 5 toward the direction of the electromagnet 11, so that the wire 2 and the card connector 9 are disconnected, and the transformer 1 stops supplying power, thereby ensuring the safety and stability of the transformer 1.

[0024] When in use, place one end of the left wire 2 inside the transformer 1 on the side of the arc-shaped sliding pad 12, turn the knob 16, so that the elliptical block 17 rotates, pushes open the L-shaped rods 15 on both sides, and the L-shaped rods 15 move horizontally back to back in the hollow groove, and the anti-skid pads on the opposite sides of the L-shaped rod 15 are disengaged from the clamping blocks 20, so that the clamping blocks 20 lose their clamping effect. At this time, the clamp 13 can move up and down in the support arm 8, so as to clamp wires 2 of different specifications. Turn the knob 16 again, the elliptical block 17 no longer squeezes the L-shaped rods 15 on both sides, so that the L-shaped rods 15 move toward each other under the action of the spring. At this time, the side of the L-shaped rod 15 contacts and clamps with the clamping block 20, and the clamping block 20 moves outward under the action of the spring. At the same time, because the slider 19 is restricted to move horizontally, the clamping block 20 clamps the L-shaped rod 15, so that the position of the clamp 13 is fixed, and the clamp 13 and the wire 2 are prevented from slipping off, After the wire 2 at the end of the output wire 3 passes through the clamp 13 from the right side, the two sections of the wire 2 are in the leakage detector 7. At this time, the left and right sides of the clamping connector 9 are clamped with different wires 2 so that the wires 2 can be connected. At this time, the wires 2 are energized. When the leakage detector 7 detects that the wire 2 is leaking, the leakage detector 7 triggers the indicator light 10, so that the indicator light 10 starts to flash as a reminder, so that other operators can maintain the transformer 1 in time. At the same time, the electromagnet 11 is energized, so that the iron block on the side of the mounting seat 6 is attracted, and the mounting seat 6 slides along the sliding groove 5 toward the direction of the electromagnet 11, thereby driving the clamp 13 to move away from the leakage detector 7, and driving the wire 2 to move away from the leakage detector 7. At this time, the wire 2 is detached from the clamping connector 9, and the wire 2 is no longer energized. At this time, the output wire 3 is powered off, so that the transformer 1 stops supplying power, thereby ensuring the safety and stability of the transformer 1.

[0025] See also Figure 5 On the basis of the first embodiment, the number of the clamps 13 is two and they are symmetrically arranged on both sides of the arc-shaped sliding pad 12. The top sides of the two clamps 13 are both threadedly connected with threaded rotating rods 14. The threaded rotating rod 14 is rotatably connected to a steering plate 21 on the side away from the clamp 13. The steering plate 21 is rotatably connected with a roller 22. The roller 22 contacts the side of the wire 2 to further clamp the wire 2, so that the wire 2 can be driven by the clamp 13. The clamp 13 is arranged in an arc structure. The roller 22 and the threaded rotating rod 14 are both made of plastic insulating material to avoid the risk of conductivity in the process of contact with the wire 2. In the utility model, the threaded rotating rod 14 drives the steering plate 21 and the roller 22 to approach the position of the wire 2, so that the roller 22 clamps the side of the wire 2. Through the rolling friction of the roller 22 on the side of the wire 2, the wire 2 can be further stably clamped to prevent it from being separated from the wire 2 when the mounting seat 6 moves.

[0026] During use, based on the first embodiment, when the wire 2 is located in the clamp 13, the threaded rotary rod 14 is rotated so that the threaded rotary rod 14 approaches the position of the wire 2, thereby driving the steering plate 21 and the roller 22 to approach the position of the wire 2, and making the roller 22 clamp the side of the wire 2. Through the rolling friction of the roller 22 on the side of the wire 2, the wire 2 can be further stably clamped to prevent it from detaching from the wire 2 when the mounting base 6 moves.

[0027] See also Figure 7 On the basis of the first embodiment, a fixed column 23 is fixedly installed on one side of the inner wall of the sliding groove 5, and a clamping groove 24 is slidably connected on the upper side of the fixed column 23. A plurality of balls 25 are clamped inside the clamping groove 24, and the balls 25 are in contact with the mounting seat 6. When the transformer 1 is hit, the collision force is weakened by the spring on the outer side of the fixed column 23, thereby reducing the impact on the mounting seat 6. The outer side of the fixed column 23 is wound with a spring, and the surface of the ball 25 is a rough material. The clamping groove 24 is slidably connected to the inner wall of the sliding groove 5. Because there is a large friction between the ball 25 and the clamping groove 24, it can play a role in slowing down the movement speed during rotation, and provide a certain resistance to the sliding of the mounting seat 6. The utility model drives the ball 25 to rotate in the clamping groove 24 through the mounting seat 6. The ball 25 can play a role in slowing down the movement speed during rotation, and provide a certain resistance to the sliding of the mounting seat 6. When the transformer 1 is hit, the collision force is weakened by the spring on the outer side of the fixed column 23, thereby reducing the impact on the mounting seat 6 and avoiding affecting the normal operation of the wire 2.

[0028] During use, based on the first embodiment, when the mounting seat 6 slides, the mounting seat 6 drives the ball 25 to rotate in the snap-in groove 24. Because there is a large friction between the ball 25 and the snap-in groove 24, it can slow down the movement speed during rotation, provide a certain resistance to the sliding of the mounting seat 6, and prevent the sliding of the mounting seat 6 from causing power failure of the wire 2. At the same time, when the transformer 1 is collided, the collision force will be weakened by the spring on the outside of the fixing column 23, thereby reducing the impact on the mounting seat 6 and avoiding affecting the normal operation of the wire 2.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
