[0023] Example 1

[0024] See also Figure 1-4 The present invention provides a technical solution: an intelligent dry-type transformer that can dissipate heat based on the Internet of Things, comprising a top plate 1 on which a low-voltage outlet copper busbar and a high-voltage terminal are installed, a bottom plate 2 with channel steel installed on both sides of the bottom, and an iron core coil assembly 3, the iron core coil assembly 3 is installed between the top plate 1 and the bottom plate 2, and an insertion hole and a conductive wire are provided on the iron core coil assembly 3, a temperature sensor 6 is installed on the inner surface of the top plate 1, a card cover 4 is sealed and fixed between the top plate 1 and the bottom plate 2, and air holes 5 with filters are provided on both sides of the middle of the front and rear surfaces of the card cover 4. The inner cavity is provided with a crossbeam 18, and the crossbeam 18 and the filter are fixed to the inner wall of the air vent 5 by bolts, which is convenient for disassembly and installation of the internal components of the card cover 4. A heat dissipation component 7 is rotatably installed between the front and rear relative crossbeams 18. The rear side of the inner wall of the card cover 4 is installed with a worm 9 and a micro high-speed motor 8 connected to each other. The worm 9 is connected to the heat dissipation component 7 through a worm gear. The temperature sensor 6 is connected to the controller, and the controller is connected to the mains module, the GPRS module and the micro high-speed motor 8. The GPRS module is connected to the client, so that the dry-type transformer can dissipate heat in time according to the Internet of Things.

[0025] The heat dissipation assembly 7 includes a square tube 71 with a mesh plate on the outside and an opening facing inward. A drive shaft 70 with fan blades is installed in the center of the mesh plate. Brushes that fit the outside of the filter are screwed on both ends of the drive shaft 70 to facilitate cleaning of accumulated dust. A first rotating shaft 72 is rotatably installed on one side of the inner wall of the mesh plate. A first wind wheel 73 is installed on the inner end of the first rotating shaft 72. A first electric lock 74 is installed on the mesh plate between the first rotating shaft 72 and the drive shaft 70. The outer walls of the first rotating shaft 72 and the drive shaft 70 are fixedly sleeved with friction concave wheels 75. The pin of the first electric lock 74 is matched with the friction concave wheels 75 on both sides through friction cams 76 for transmission. The micro high-speed motor 8 rotates the worm gear through the worm 9, and then the drive shaft 70 rotates. The rotating friction cam 76 is squeezed and fitted with the friction concave wheels 75 on both sides, so that the first wind wheel 73 is exhausted, and the temperature inside the card cover 4 is reduced. At this time, the dry-type transformer is closed.

[0026] Example 2

[0027] See also Figure 2 、4 and 5. The left and right surfaces of the card cover 4 are provided with a stepped through groove 10 in front and behind. The inner wall of the outer port of the stepped through groove 10 is provided with a retaining ring. A partition 17 is fixed to the vertical center of the retaining ring. A folding door panel 16 is slidably installed in the stepped through groove 10. The inner cavity of the card cover 4 is provided with a threaded rod 11 on both sides for parallel rotation. The outer wall of the threaded rod 11 is provided with a threaded sleeve 12 in front and behind. The lower part of the threaded sleeve 12 is connected to the outer wall of the central axis of the folding door panel 16 through an electric push rod 15. The front side of the inner wall of the card cover 4 is provided with a threaded rod 11 on both sides for parallel rotation. The spur gear pair is provided with a transmission shaft 13 and a forward and reverse motor 14. Both ends of the transmission shaft 13 are connected to the threaded rod 11 through a bevel gear pair. The electric push rod 15 contracts to fold the folding door panel 16 toward the center. The forward and reverse motor 14 drives the transmission shaft 13 to make the threaded rod 11 drive the threaded sleeve 12 to move, and then the stepped groove 10 opens. When the folding door panel 16 is squeezed and closed by the electric push rod 15, sealing strips are provided on the inner surfaces of the retaining ring and the partition 17 to improve the sealing performance.

[0028] The heat dissipation assembly 7 also includes a second rotating shaft 77 that is rotatably connected. The second rotating shaft 77 is symmetrical with the first rotating shaft 72 about the center of the drive shaft 70. The inner end of the second rotating shaft 77 is fixed with a second wind wheel 78 that rotates in the opposite direction to the first wind wheel 73. A second electric latch 79 is installed on the mesh plate between the second rotating shaft 77 and the drive shaft 70. The outer wall of the second rotating shaft 77 is also fixedly sleeved with a friction concave wheel 75. The pin of the second electric latch 79 is also fixed with a friction cam 76 that is frictionally connected to the friction concave wheels 75 on both sides. At this time, the second electric latch 79 is fixed with a friction cam 76 that is frictionally connected to the friction concave wheels 75 on both sides. When the first electric lock 74 loses power, the second electric lock 79 gains power, causing the second wind wheel 78 and the fan blades to blow air into the inner cavity of the card cover 4, and heat is dissipated from the stepped grooves 10 on both sides. The second electric lock 79 and the first electric lock 74 are connected to the mobile phone remote control switch group, which is connected to the electric push rod 15, the forward and reverse motor 14, the step-down rectifier and the mains module. The step-down rectifier is connected to the mains module. The mobile phone remote control switch group is combined with the mobile phone display time to facilitate remote control. At this time, the dry-type transformer is in the open mode.

[0029] Working principle: the card cover 4 seals the dry-type transformer, and the temperature sensor 6 is matched with the controller to enable the micro high-speed motor 8 to drive the heat dissipation component 7 for front and rear ventilation and heat dissipation; then the forward and reverse motor 14, the electric push rod 15, the threaded rod 11 and the threaded sleeve 12 are used to open the folding door panel 16, and the left and right sides of the card cover 4 are opened. Then the second electric lock 79 in the heat dissipation component 7 is energized, so that the second wind wheel 78 and the fan blades blow air into the inner cavity of the card cover 4, and the heat is dissipated from the stepped grooves 10 on both sides to complete relative blowing. The dry-type transformer can be used as an open or closed type.
