[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 to 5 shown, this embodiment proposes a static and dynamic contact connection device, including a base plate 1. A static contact box 2 is fixedly connected to the top of the base plate 1. A static contact 3 is fixedly connected to the inside of the static contact box 2.

A connection frame 46 is fixedly connected to the circumferential surface of the threaded sleeve 45. A casting contact 47 is fixedly connected to the side of the connection frame 46. A contact piece 48 is fixedly connected to the side of the casting contact 47.

[0030] A chute 49 is opened on the top of the base plate 1. A door panel 410 is slidably connected to the inside of the chute 49. A limit block 411 is fixedly connected to the top of the static contact box 2. A first limit groove 412 is opened in the inside of the limit block 411. The door panel 410 is slidably connected to the inside of the first limit groove 412. Such a design is beneficial to open or close the device by sliding the door panel 410.

[0031] A handle 413 is fixedly connected to the side surface of the door panel 410, and a first limiting plate 414 is fixedly connected to the side surface of the static contact box 2. Such a design is beneficial to limit the displacement of the door panel 410 through the first limiting plate 414.

[0032] The door panel 410 is located on the displacement track of the contact piece 48, and the first limiting plate 414 is located on the displacement track of the door panel 410. Such a design is beneficial for connection to be carried out only after the door panel 410 is opened.

[0033] In this embodiment, when connection is required, first slide the door panel 410 to open the static contact box 2, and then start the motor 41. When the motor 41 is started, the threaded rod 43 on the output shaft of the motor 41 rotates clockwise.

When the threaded sleeve 45 moves horizontally to the left, the casting contact 47 connected to the threaded sleeve 45 through the connecting frame 46 moves horizontally to the left. When the casting contact 47 moves horizontally to the left, the contact piece 48 is disconnected from the static contact 3.

[0034] Embodiment 2

[0035] As Figures 1 to 5 shown, on the premise of the same concept as the above Embodiment 1, a second embodiment is also proposed. A heat dissipation device 5 is provided on the top of the bottom plate 1. The heat dissipation device 5 includes a connecting plate 51. The side surface of the connecting plate 51 is fixedly connected to the side surface of the static contact box 2. A connecting shaft 52 is rotatably connected inside the connecting plate 51. A driving bevel gear 53 is fixedly penetrated through the circumferential surface of the threaded rod 43, and a driven bevel gear 54 is fixedly penetrated through the circumferential surface of the connecting shaft 52. The circumferential surface of the driving bevel gear 53 meshes with the circumferential surface of the driven bevel gear 54. A fan blade frame 55 is fixedly connected to the top of the bottom plate 1. A rotating shaft 56 is rotatably connected inside the fan blade frame 55. A first belt groove 57 is formed on the circumferential surface of the connecting shaft 52, and a second belt groove 58 is formed on the circumferential surface of the rotating shaft 56. A belt 59 is drivingly connected to the circumferential surface of the first belt groove 57. The inner side surface of the belt 59 is on the circumferential surface of the second belt groove 58. A blade 510 is fixedly connected to the circumferential surface of the rotating shaft 56. A ventilation opening 511 is formed on the side surface of the static contact box 2. Such a design is beneficial for the driving bevel gear 53 to mesh with the driven bevel gear 54, so that when the threaded rod 43 rotates, it drives the connecting shaft 52 to rotate, and through the belt 59, when the connecting shaft 52 rotates, it drives the rotating shaft 56 to rotate.

[0036] A second limiting plate 512 is fixedly connected to the side surface of the static contact box 2. A baffle groove 513 is formed inside the second limiting plate 512. A first baffle 514 is slidably connected inside the baffle groove 513. Such a design is beneficial to closing the ventilation opening 511 through the first baffle 514.

[0037] A second limiting groove 515 is formed in the side surface of the second limiting plate 512. A second baffle 516 is slidably connected inside the second limiting groove 515. Such a design is beneficial to restricting the first baffle 514 through the second baffle 516.

[0038] The number of the blades 510 is set to six, and they are arranged in a circumferential array on the circumferential surface of the rotating shaft 56. The second baffle 516 is located on the displacement track of the first baffle 514. Such a design is beneficial to achieving better heat dissipation through multiple blades 510.

[0039] In this embodiment, when heat dissipation is required, first slide the second baffle 516 to open the ventilation opening 511 with the first baffle 514, and then start the motor 41. When the motor 41 starts, the threaded rod 43 on the output shaft of the motor 41 rotates clockwise. When the threaded rod 43 rotates clockwise, the driving bevel gear 53 on the threaded rod 43 meshes with the driven bevel gear 54 on the connecting shaft 52, causing the connecting shaft 52 to rotate counterclockwise. When the connecting shaft 52 rotates counterclockwise, the rotating shaft 56 driven by the belt 59 and the connecting shaft 52 rotates counterclockwise. When the rotating shaft 56 rotates counterclockwise, the blades 510 on the rotating shaft 56 dissipate heat to the interior of the device through the ventilation opening 511. When the threaded rod 43 rotates counterclockwise, the driving bevel gear 53 on the threaded rod 43 meshes with the driven bevel gear 54 on the connecting shaft 52, causing the connecting shaft 52 to rotate clockwise. When the connecting shaft 52 rotates clockwise, the rotating shaft 56 driven by the belt 59 and the connecting shaft 52 rotates clockwise. When the rotating shaft 56 rotates clockwise, the blades 510 on the rotating shaft 56 cannot dissipate heat to the interior of the device through the ventilation opening 511.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
