[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

The heat is always accumulated in the rotor. The guide vane on the connecting tube is driven to move when the rotor rotates. When moving, the guide vane will resist the wind pressure. With the cooperation of the rotating rod, the swing vane on the guide vane can be tilted to form an inclined surface, which can allow the air in the rotor to flow out under the action of the inclined surface, thereby accelerating the heat dissipation of the rotor, ensuring the service life of the rotor, and avoiding damage to surrounding parts caused by heat accumulation.

[0015] 2. A protective layer is provided in the present invention. By providing a high-temperature resistant layer, the basic working conditions of the rotor are met. When resisting high temperatures, it can be ensured that the heat will not cause the rotor to deform.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes an eddy current retarder rotor disk provided by some embodiments of the present invention with reference to the accompanying drawings.

[0024] Combine Figure 1-4 As shown, the utility model provides an eddy current retarder rotor disk, including a rotor body 1, the inner wall of the rotor body 1 is annularly fixedly connected with a connecting rib 2, one end of the connecting rib 2 is fixedly connected to a fixing ring 3, one end of the fixing ring 3 is fixedly connected to a connecting tube 6, the outer wall of the connecting tube 6 is annularly fixedly connected with a drainage plate 7, one end of the drainage plate 7 is fixedly connected to a rotating sleeve 8, one side of the rotating sleeve 8 is fixedly connected to a swinging plate 11, the inner wall of the rotating sleeve 8 is fixedly connected to a rotating rod 9, and both ends of the rotating rod 9 are fixedly connected to a torsion spring 10. The rotating rod 9 and the torsion spring 10 are provided to allow the swinging plate 11 to return to its original position without being affected by wind pressure. After returning to its original position, the swinging plate 11 can form a barrier, thereby preventing some external dust from entering the equipment, thereby protecting the equipment. The inner wall of the rotor body 1 is fixedly connected with a connecting ring 4, one side of the connecting ring 4 is annularly fixedly connected with a heat sink 5, the number of connecting ribs 2 is eight, and the number of drainage plates 7 is eight.

[0025] In the first embodiment, when the rotor body 1 rotates, the connecting ribs 2 can ensure the strength of the rotor body 1 during rotation, and the heat sink 5 on the connecting ring 4 can conduct the heat on the rotor body 1 to accelerate the heat dissipation of the rotor body 1. At the same time, when the rotor body 1 rotates, the connecting tube 6 on the fixed ring 3 can drive the drainage plate 7 to move. When the drainage plate 7 moves, it will drive the swing plate 11 to move through the rotating sleeve 8. When the swing plate 11 moves, it will resist the wind pressure. The wind pressure will squeeze the swing plate 11 to move, thereby forming an inclined posture. The inclined posture can allow the wind pressure to be guided out of the rotor body 1 when it blows on the swing plate 11, thereby allowing the gas to circulate normally. In this way, excessive heat accumulation in the rotor body 1 can be avoided, which not only ensures the service life of the rotor body 1, but also ensures the service life of surrounding parts.

[0026] A high-temperature resistant layer 12 is pressed on the surface of the rotor body 1, a connecting layer 13 is pressed on one side of the high-temperature resistant layer 12, and a reinforcing layer 14 is pressed on one side of the connecting layer 13. The high-temperature resistant layer 12 is a nickel-based alloy, the connecting layer 13 is mainly made of borax, and the reinforcing layer 14 is carbon steel.

[0027] In the second embodiment, the high temperature resistant layer 12 can make the rotor body 1 resistant to high temperatures, so that the rotor body 1 will not be deformed due to high temperature, affecting normal operation. The connecting layer 13 can connect the reinforcing layer 14 and the high temperature resistant layer 12. The connecting layer 13 and the reinforcing layer 14 can be adsorbed together through the action of borax, and at the same time, the corrosion resistance of the rotor body 1 can be increased. The reinforcing layer 14 serves as the base layer of the rotor body 1, and its strength must meet the standard, thereby ensuring that the rotor body 1 can adapt to the high-intensity working mode.

[0028] The working principle and usage process of the present invention are as follows: when the rotor body 1 is rotating, it can be rotated through the connecting tube 6 on the fixing ring 3. When the connecting tube 6 is rotating, it can drive the drainage plate 7 to move. The swinging plate 11 on the drainage plate 7 will swing under the action of wind pressure. When swinging, the swinging plate 11 can produce an inclined posture, thereby draining the hot air in the rotor body 1. At the same time, the high-temperature resistant layer 12 can make the rotor body 1 resist high temperature. The connecting layer 13 can adsorb the reinforcing layer 14 and the high-temperature resistant layer 12, so that the two can be perfectly forged together. The reinforcing layer 14 can strengthen the strength of the rotor body 1, thereby ensuring the service life of the rotor body 1.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
