DETAILED DESCRIPTION

[0021] 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 the embodiments.

[0022] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A protective structure for an amorphous alloy power transformer includes a shell 1 and a transformer body 2, wherein the shell 1 is fixedly connected to the upper end surface of the transformer body 2.

[0024] A protection mechanism is provided in the shell 1, which includes a gas cylinder 3, a push plate 4, a push rod 5, a limit plate 6, a liquid storage cylinder 7, a piston plate 8, a connecting rod 9, an equilateral triangle block 10, and a baffle 23. The gas cylinder 3 is fixedly connected to the top wall of the transformer body 2, the push plate 4 is slidably connected in the gas cylinder 3, an extrusion spring 21 is fixedly connected between the gas cylinder 3 and the push plate 4, the push rod 5 is fixedly connected to the side wall of the push plate 4, the push rod 5 is slidably connected to the shell 1 and the transformer body 2, the limit plate 6 is fixedly connected to the side wall of the push rod 5 away from the push plate 4, a certain amount of gas is stored in the gas cylinder 3, and the gas volume is small when the temperature is low. Under the action of the compression spring 21, the push plate 4 is pressed to the bottom end of the gas cylinder 3, driving the push rod 5 and the limit plate 6 to the bottom end. As the temperature rises, the gas in the gas cylinder 3 expands, driving the push plate 4, the push rod 5 and the limit plate 6 to rise. The liquid storage cylinder 7 is fixedly connected to the bottom wall of the shell 1, the piston plate 8 is slidingly connected to the side wall of the liquid storage cylinder 7, the connecting rod 9 is fixedly connected to the side wall of the piston plate 8, the equilateral triangle block 10 is fixedly connected to the upper end face of the connecting rod 9, the baffle 23 is fixedly connected to the side wall of the equilateral triangle block 10 close to the gas cylinder 3, and a return spring 22 is fixedly connected between the liquid storage cylinder 7 and the equilateral triangle block 10.

[0025] The protection mechanism also includes a motor 11, a rotating rod 12, and an inverted triangle block 13. The motor 11 is fixedly connected to the top wall of the shell 1, the rotating rod 12 is fixedly connected to the output end of the motor 11, the rotating plate is fixedly connected to the end of the rotating rod 12 away from the motor 11, and the two inverted triangle blocks 13 are respectively fixedly connected to the two ends of the rotating plate.

[0026] The upper end of the rotating rod 12 is provided with a reciprocating thread pattern, and a nut seat 14 is threadedly connected to the rotating rod 12. The side wall of the nut seat 14 is fixedly connected to a connecting plate, and an air bag 15 is fixedly connected between the connecting plate and the shell 1. The side wall of the transformer body 2 is fixedly connected to a jet pipe 19, and an air outlet pipe 20 is fixedly communicated between the air bag 15 and the jet pipe 19. The side wall of the jet pipe 19 is provided with a plurality of holes. A one-way valve is provided in the air bag 15 and the air outlet pipe 20. The one-way flow direction of the air bag 15 is from the outside to the air bag 15, and the air outlet pipe 20 is one-way from the air bag 15 to the air outlet pipe 20. The rotation of the rotating rod 12 drives the nut seat 14 to reciprocate up and down, reciprocatingly squeezing and stretching the air bag 15. When the air bag 15 is stretched, it inhales air from the outside, and when it is compressed, it sends the gas along the outlet pipe 20 to the jet pipe 19. Each hole on the jet pipe 19 is located directly above the heat sink, and the blown gas is more concentrated and has a good effect.

[0027] A plurality of heat sinks are provided on the side wall of the transformer body 2. A nozzle 16 is fixedly connected to the side wall of the transformer body 2. A plurality of holes are opened on the side wall of the nozzle 16. A liquid storage tank 17 is fixedly connected to the shell 1. The liquid storage tank 17 and the liquid storage cylinder 7 are fixedly connected through an inlet pipe. The liquid storage cylinder 7 and the nozzle 16 are connected through an outlet pipe 18. A one-way valve is provided in both the inlet pipe and the outlet pipe 18, so that the liquid flows from the liquid storage tank 17 to the liquid storage cylinder 7 in one direction and from the liquid storage cylinder 7 to the nozzle 16 in one direction. The rotation of the rotating rod 12 drives the rotating plate and the inverted triangle block 13 to move. The inverted triangle block 13 is close to the equilateral triangle block 1 0, and compress the return spring 22. The equilateral triangle block 10 moves downward, driving the connecting rod 9 and the piston plate 8 to move downward, so that the liquid reservoir 7 is under negative pressure, and the coolant stored in the liquid storage tank 17 is drawn into the liquid reservoir 7. When the inverted triangle block 13 approaches the equilateral triangle block 10, the equilateral triangle block 10 is reset under the action of the return spring 22, driving the connecting rod 9 and the piston plate 8 to reset, and injecting the coolant into the nozzle 16 along the liquid outlet pipe 18, and spraying it onto the heat sink from the hole in the nozzle 16. Under the action of the air bag 15 and the injection pipe 19, the coolant quickly evaporates and absorbs heat, thereby lowering the temperature.

[0028] In the present invention, when in use, the motor 11 first drives the rotating rod 12 to rotate, driving the nut seat 14 and the connecting plate to reciprocate up and down on a section of the rotating rod 12 with reciprocating silk patterns, and reciprocatingly squeezes the air bag 15. The gas in the air bag 15 comes to the injection pipe 19 through the outlet pipe 20, accelerating the air flow on the surface of the heat sink and improving the heat dissipation effect. The rotation of the rotating rod 12 drives the rotating plate and the inverted triangular block 13 to move. When the inverted triangular block 13 approaches the equilateral triangular block 10, it is squeezed and the return spring 22 is compressed. The equilateral triangular block 10 moves downward, driving the connecting rod 9 and the piston plate 8 to move downward, so that the liquid storage cylinder 7 is negatively pressurized, and the coolant stored in the liquid storage tank 17 is drawn into the liquid storage cylinder 7. When the inverted triangular block 13 approaches the equilateral triangular block 10, the equilateral triangular block 10 is reset under the action of the return spring 22, driving The connecting rod 9 and the piston plate 8 are reset, and the coolant is injected into the nozzle 16 along the liquid outlet pipe 18, and is sprayed onto the heat sink from the hole in the nozzle 16. Under the action of the air bag 15 and the injection pipe 19, the coolant evaporates quickly and absorbs heat, thereby lowering the temperature. A certain amount of gas is stored in the cylinder 3. When the temperature is low, the volume of the gas is small. Under the action of the extrusion spring 21, the push plate 4 is pressed to the bottom end of the cylinder 3, driving the push rod 5 and the limit plate 6 to the bottom end, and pressing the baffle 23 to the bottom end. At this time, the regular triangle block 10 is not in contact with the inverted triangle block 13, and the coolant will not be extracted for cooling. When the heat generated inside the transformer is large, the temperature rises, causing the gas in the cylinder 3 to expand, driving the limit plate 6 and the baffle 23 to rise. The higher the temperature, the higher the rise, the more coolant is extracted, and the better the cooling effect.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
