[0027] In one embodiment, Figure 1-10As shown, a relay includes a base 1, a component 5 is fixedly connected to the top of the base 1, two transparent frames 2 are provided on the outer edges of the component 5, and the corresponding sides of the transparent frames 2 are each provided with a slot, and the two slotted inner cavities are jointly provided with an elastic plate 15, and the bottom of each slot is provided with two slide grooves, and the inner cavities of the slide grooves are movably connected to sliders 20, and the tops of the sliders 20 are fixedly connected to the bottoms of the elastic plates 15, three first threaded holes are provided at the bottom of the transparent frame 2, three second threaded holes are provided at the bottom of the base 1 near the left and right sides, and bolts 16 are commonly threadedly connected to the inner cavities of adjacent first threaded holes and second threaded holes, and a plurality of through holes are provided on the side of the transparent frame 2 away from the center of the base 1, and two arc grooves are provided on the side of the transparent frame 2 away from the center of the base 1, and the inner cavities of the arc grooves are fixedly connected to second magnets 14;

[0028] A circular frame 3 is provided on one side of the transparent frame 2 away from the center of the base 1. The top and bottom of the circular frame 3 are fixedly connected to a vertical plate 8. A third threaded hole is opened in the inner cavity of the vertical plate 8. The inner cavity of the third threaded hole is threadedly connected to a connecting threaded rod 9. The connecting threaded rod 9 is plugged with a first magnet 7 at one end close to the transparent frame 2. The adjacent first magnet 7 and the second magnet 14 are arranged to fit each other. A motor 10 is provided on the side of the circular frame 3 away from the transparent frame 2. The power output shaft of the motor 10 is fixedly connected to a transmission rod 12. The end of the transmission rod 12 away from the motor 10 passes through the adjacent side of the circular frame 3, and the outer edge of the transmission rod 12 is fixedly connected to a blade 13. Four fan-shaped grooves are provided on the side of the round frame 3 away from the transparent frame 2. The inner cavities of the fan-shaped grooves are fixedly connected to the filter plates 11. Four iron plates 6 are fixedly connected to the bottom of the base 1 near the front and rear sides. The outer edges of the iron plates 6 are sleeved with vertical frames 4. An elastic rod 17 is fixedly connected between two adjacent vertical frames 4. The vertical frames 4 are fixedly connected to horizontal plates 18 near the top on both sides. The inner cavities of the horizontal plates 18 are provided with fourth threaded holes. Several fifth threaded holes are provided at the bottom of the base 1. The inner cavities of the fourth threaded holes are all threadedly connected to limit threaded rods 19. The top of the limit threaded rod 19 is threadedly connected to the inner cavities of the adjacent fifth threaded holes.

[0029] Place the transparent frame 2 on top of the base 1 and limit the transparent frame 2 with bolts 16. If protection is required for bases 1 and components 5 of different sizes, move the transparent frame 2 left and right to expose the elastic plate 15 between the two transparent frames 2. The transparent frame 2 can then be installed on bases 1 of different sizes. Install the circular frame 3 on the second magnet 14 through the first magnet 7. The motor 10 drives the blades 13 to rotate, and the blades 13 dissipate heat for the component 5. At the same time, the vertical frame 4 will protect the iron plate 6 when the relay is not in use.

[0030] Working principle: When the relay is used for a long time, the component 5 may heat up. The operator takes out the round frame 3, places the round frame 3 on the side of the transparent frame 2, rotates the connecting threaded rod 9, and the connecting threaded rod 9 drives the first magnet 7 to move. The first magnet 7 gradually approaches the second magnet 14. The adjacent first magnets 7 and second magnets 14 will fit together and adsorb, thereby limiting the round frame 3. The motor 10 is started by an external power supply. The motor 10 drives the transmission rod 12 to rotate. The transmission rod 12 drives the blade 13 to rotate. The blade 13 dissipates heat to the component 5 through the holes on the side of the transparent frame 2. The filter plate 11 can filter impurities in the air. When the internal component 5 of the relay is When a fault occurs, the operator first turns the bolt 16 and removes the bolt 16 from the base 1 and the transparent frame 2, and then the transparent frame 2 can be removed, the component 5 is exposed, and the component 5 can be repaired or replaced. The transparent frame 2 can be used for the base 1 of relays of different sizes. The length of the transparent frame 2 can be adjusted. By pulling the transparent frame 2, the elastic plate 15 between the two transparent frames 2 is exposed, which can increase the reuse rate of the transparent frame 2. When the relay is not working, the vertical frame 4 is put on the surface of the adjacent iron plate 6, and the limiting threaded rod 19 is taken out. The top of the limiting threaded rod 19 passes through the adjacent horizontal plate 18 and is rotated to the bottom of the base 1, thereby limiting the vertical frame 4 and improving the service life of the device.
