specific Embodiment 1

[0048] The grounding switch includes a frame, and an opening and closing mechanism and a grounding switch 6 are arranged on the frame. like figure 1 , figure 2 , image 3 As shown, the opening and closing mechanism includes an opening and closing drive shaft 1, which is rotatably assembled on the frame, and the opening and closing drive shaft 1 is connected with a moving contact. , the grounding switch can be switched between the closed position and the open position.

[0049] The opening and closing mechanism also includes a driving mechanism for driving the opening and closing transmission shaft 1 to rotate. The driving mechanism includes a driving motor 2 and a gear group 3. The driving shaft of the driving motor 2 is driven and matched with the opening and closing transmission shaft 1 through the gear group 3. . Specifically, the gear set 3 includes an input gear 31 fixedly connected to the driving shaft of the drive motor 2 , a transmission shaft gear 32 and an inter...

specific Embodiment 7

[0062] The specific embodiment 7 of the grounding switch of the present invention differs from the above-mentioned embodiments only in that there is one bump. In other embodiments, the number of bumps may also be two or four.

specific Embodiment 8

[0063] The specific embodiment 8 of the grounding switch of the present invention differs from the above-mentioned embodiments only in that the clutch mechanism is arranged between the intermediate gear transmission shaft and the second gear. In other embodiments, the clutch mechanism may also be arranged between the input gear and the intermediate gear set, between the main shaft of the driving motor and the book infiltration gear, and the like.

[0064] The specific embodiment of the switch electrically operated opening and closing mechanism of the present invention is: the specific structure of the switch electrically operated opening and closing mechanism is the same as that of the opening and closing mechanism in any one of the above-mentioned embodiments 1-8.

Abstract

The invention relates to the technical field of operating devices, in particular to a transmission structure of an electric operating device. The invention aims to protect a switch electrically-operated opening and closing mechanism and a grounding switch, the switch electrically-operated opening and closing mechanism comprises an opening and closing transmission shaft and a transmission shaft gear in transmission fit with the opening and closing transmission shaft, the opening and closing transmission shaft is connected with an energy storage spring through a crank arm, and the energy storage spring can be compressed to store energy during rotation; one of the power transmission shaft transmission shaft gear and the opening and closing transmission shaft is provided with a groove, the other one is provided with a convex block extending into the groove, and the convex block can move in the groove relative to the groove; when the elastic potential energy of the energy storage spring is released, the opening and closing transmission shaft is driven to accelerate rotation, the protruding block can move by a stroke relative to the groove, and in the process, the elastic potential energy releasing process of the energy storage spring is not hindered by the driving motor; the problem that according to an existing switching-on and switching-off mechanism, due to the fact that elastic potential energy release of an energy storage spring is blocked, switching-on and switching-off of a switch are not in place can be solved.

Description

technical field [0001] The present invention relates to the technical field of operating devices, in particular to a transmission structure of an electric operating device. Background technique [0002] The electric quick grounding switch can realize quick opening and closing through the operating mechanism. The operating mechanism is generally composed of a drive motor, an opening and closing drive shaft, and an energy storage spring. During operation, the drive motor drives the opening and closing transmission shaft to rotate, and the energy storage spring is compressed by the arm when the opening and closing transmission shaft rotates. After the energy storage spring passes the dead point, the elastic potential energy is released, and torque is applied to the opening and closing drive shaft, so that the opening and closing drive shaft rotates rapidly; when the opening and closing drive shaft rotates rapidly, it drives the knife to complete the rapid opening or closing act...
