[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] See also Figure 1-Figure 3As shown, the utility model provides a high voltage and high current phase selection closing device, comprising a moving component 1, a rotating component 2 is arranged on the moving end of the moving component 1, and the moving component 1 can drive the rotating component 2 to move along a straight line;

[0032] The mounting plate 3 is fixed on the rotating shaft 16 of the rotating assembly 2, and the rotating assembly 2 can drive the mounting plate 3 to rotate;

[0033] Two mutually parallel guide plates 5 are arranged on the side of the mounting plate 3, and the conductive contact rod of the switch can be accommodated between the two guide plates 5. A top rod 4 is arranged on the side of the mounting plate 3, and an electric push rod 6 is arranged on the side of the mounting plate 3. A mounting frame 7 is arranged on the movable end of the electric push rod 6, and two symmetrical fixing plates 15 are arranged on the mounting frame 7;

[0034] The mobile component 1 is provided with a phase detection module 17 and a control module 18, the phase detection module 17 is electrically connected to the control module 18, and the control module 18 is connected to all the above electrical appliances. The phase detection module 17 is a prior art, and its function is not repeated here.

[0035] As an optional embodiment, the moving component 1 includes a slide rail 8 for guiding the rotating component 2, a mounting plate 11 is provided on the slide rail 8, and a plurality of mounting holes are provided on the mounting plate 11, and an electric push rod 10 is provided in the slide rail 8 for moving the rotating component 2.

[0036] The rotating component 2 includes a movable plate 9, which is slidably arranged in the slide rail 8, and the movable plate 9 is fixed to the movable end of the electric push rod 10. A rotating shaft 16 is rotatably arranged on the movable plate 9, and a mounting plate 3 is fixed to the end of the rotating shaft 16, and an outer gear ring 14 is arranged on the mounting plate 3. A motor 12 is fixed on the movable plate 9, and a gear 13 is fixed on the output shaft of the motor 12, and the gear 13 is meshed with the outer gear ring 14. The movable component 1 drives the rotating component 2 to move in a straight line through the electric push rod 10. On the one hand, it is necessary to press the button of the push-button switch through the push rod 4, and on the other hand, it is necessary to adjust the position of the two fixed plates 15 through the cooperation of the movable component 1 and the rotating component 2 so that the fixed plates 15 are in the accurate position.

[0037] The guide plate 5 is misaligned with the push rod 4 and the electric push rod 6 in the length direction, so as to avoid the interference between the conductive contact rod and the push rod 4.

[0038] The end of the push rod 4 protrudes from the edge of the mounting plate 3, and the push rod 4 is used to press the button of the push-button switch.

[0039] The fixed plate 15 is tilted on the mounting frame 7, and the two fixed plates 15 are close to each other on the side away from the mounting frame 7. The tilted setting makes it easier for the fixed plate 15 to push the knife switch of the electric switch. Because the trajectory of the knife switch swinging up and down is an arc, the tilted design can make the thrust direction of the fixed plate 15 adapt to the movement direction of the knife switch.

[0040] The radius of the gear 13 is smaller than the radius of the outer gear ring 14 , so that the torque of the outer gear ring 14 transmitted by the gear 13 can be amplified.

[0044] For the push-button switch, the mounting plate 3 is rotated by the rotating assembly 2, and the top rod 4 is rotated by the mounting plate 3, so that the end of the top rod 4 corresponds to the push-button switch of the switch, and then the rotating assembly 2, the mounting plate 3 and the top rod 4 are moved by the moving assembly 1, so that the top rod 4 presses the button to realize the opening and closing of the switch;

[0045] For the knife switch type switch, the positions of the two fixed plates 15 are adjusted by the rotating component 2 and the moving component 1, so that the two fixed plates 15 correspond to the upper and lower sides of the knife switch respectively, and then the two fixed plates 15 are driven to move vertically by the electric push rod 16, and the knife switch can be pushed by the cooperation of the two fixed plates 15 to realize the closing of the switch;

[0046] The phase detection module 17 determines the opening and closing timing of the switch, and the control module 18 can control all electrical appliances.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
