It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1-2The present invention provides a technical solution: a multi-axis rotary electric mechanism is driven sequentially by one machine, including an electric rotary operating mechanism 1, a first rotating shaft 2, a second rotating shaft 3, a third rotating shaft 4 and a fourth rotating shaft 5; the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 are rotatably arranged at intervals and parallel to each other along one side of the electric rotary operating mechanism 1, a first transmission gear 6 is slidably and vertically arranged on the surface of the first rotating shaft 2, a second transmission gear 7 is slidably and vertically arranged on the surface of the second rotating shaft 3, a third transmission gear 8 is slidably and vertically arranged on the surface of the third rotating shaft 4, and a fourth transmission gear 9 is slidably and vertically arranged on the surface of the fourth rotating shaft 5.

[0020] The first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 can rotate. According to the use requirements of the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5, the first rotating shaft 2 and the second rotating shaft 3 each correspond to operate a disconnector, and the third rotating shaft 4 and the fourth rotating shaft 5 each correspond to operate a grounding switch knife. Assuming that the initial state is that the disconnector is in the open state and the grounding switch is in the closed state, the power supply operation is performed, and the action sequence is as follows: first open the first rotating shaft 2, then open the second rotating shaft 3, then the third rotating shaft 4, and then close the fourth rotating shaft 5.

[0021] A bottom plate 23 is laterally fixedly connected to the bottom of one side of the electric rotary operating mechanism 1, and a fixing frame 15 is vertically fixedly connected to the top of the bottom plate 23. The first transmission gear 6, the second transmission gear 7, the third transmission gear 8 and the fourth transmission gear 9 are all located in the inner cavity of the fixing frame 15. A first driving gear 10, a second driving gear 11, a third driving gear 13 and a fourth driving gear 14 are rotatably arranged at intervals along the vertical direction on one side of the inner wall surface of the fixing frame 15. The first driving gear 10 corresponds to the first transmission gear 6, the second driving gear 11 corresponds to the second transmission gear 7, the third driving gear 13 corresponds to the third transmission gear 8, and the fourth driving gear 14 corresponds to the fourth transmission gear 9. A transmission shaft 20 is rotatably arranged on one side of the inner wall surface of the fixing frame 15, and a connecting gear 12 meshing with the second driving gear 11 and the third driving gear 13 is vertically fixedly connected to the surface of the transmission shaft 20.

[0022] The bottom plate 23 extends to a suitable position. After extending to a suitable position through the bottom plate 23, the fixing frame 15 is supported by the bottom plate 23. The first transmission gear 6, the second transmission gear 7, the third transmission gear 8 and the fourth transmission gear 9 all pass through the fixing frame 15, and a bearing is provided at each penetration. The first driving gear 10 is meshed with the second driving gear 11, and the third driving gear 13 is meshed with the fourth driving gear 14. The transmission shaft 20 drives the connecting gear 12 to mesh with the second driving gear 11 and the third driving gear 13, thereby driving the first driving gear 10 to mesh with the fourth driving gear 14, so as to rotate.

[0023] One end of the surface of the first rotating shaft 2 is fixedly connected to the first electromagnet 16, one end of the surface of the second rotating shaft 3 is fixedly connected to the second electromagnet 17, one end of the surface of the third rotating shaft 4 is fixedly connected to the third electromagnet 18, one end of the surface of the fourth rotating shaft 5 is fixedly connected to the fourth electromagnet 19, and the other ends of the surfaces of the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 are all vertically fixedly connected to a magnetic block 22.

[0024] When the transmission shaft 20 rotates clockwise, the connecting gear 12 drives the first driving gear 10, the second driving gear 11, the third driving gear 13 and the fourth driving gear 14 to rotate. When the first rotating shaft 2 needs to be rotated, the first electromagnet 16 slides the first transmission gear 6 along the surface of the first rotating shaft 2 to move it to the top of the first driving gear 10. The first driving gear 10 meshes with the third transmission gear 8. When the transmission shaft 20 rotates through the connecting gear 12, the first driving gear 10 meshes with the first transmission gear 6, thereby driving the first rotating shaft 2 to rotate and driving the corresponding grounding switch to open. After the grounding switch is opened, when there is no need to rotate the first rotating shaft 2, the power supply of the first electromagnet 16 is cut off, and the first transmission gear 6 is reset along the surface of the first rotating shaft 2 in a direction away from the first driving gear 10 through the magnetic block 22.

[0025] When the second rotating shaft 3 needs to be rotated, the second electromagnet 17 is used to slide the second transmission gear 7 along the surface of the second rotating shaft 3 to move it to the top of the second driving gear 11. The second electromagnet 17 is used to slide the second transmission gear 7 along the surface of the second rotating shaft 3 to move it to the top of the second driving gear 11. The second driving gear 11 is meshed with the third transmission gear 8. Under the clockwise rotation of the transmission shaft 20 through the transmission of the connecting gear 12, the second driving gear 11 is meshed with the second transmission gear 7, thereby driving the second rotating shaft 3 to rotate and driving the corresponding grounding switch to open. After the grounding switch is opened, when there is no need to rotate the second rotating shaft 3, the power supply of the second electromagnet 17 is cut off, and the second transmission gear 7 is reset along the surface of the second rotating shaft 3 in the direction away from the second driving gear 11 through the magnetic block 22.

[0026] When the third rotating shaft 4 needs to be rotated, the third electromagnet 18 is used to slide the third transmission gear 8 along the surface of the third rotating shaft 4 to move it to above the second driving gear 11, and the third electromagnet 18 is used to slide the third transmission gear 8 along the surface of the third rotating shaft 4 to move it to above the third driving gear 13, and the third driving gear 13 is meshed with the third transmission gear 8. Under the clockwise rotation of the transmission shaft 20 through the transmission of the third driving gear 13, the third driving gear 13 is meshed with the third transmission gear 8, thereby driving the third rotating shaft 4 to rotate, and driving the corresponding isolating switch to close it. After the isolating switch is closed, when there is no need to rotate the third rotating shaft 4, the power supply of the third electromagnet 18 is cut off, and the third transmission gear 8 is reset along the surface of the third rotating shaft 4 in a direction away from the third driving gear 13 through the magnetic block 22.

[0027] When the fourth rotating shaft 5 needs to be rotated, the fourth electromagnet 19 is used to slide the fourth transmission gear 9 along the surface of the fourth rotating shaft 5 to move it to the top of the second driving gear 11, and the fourth electromagnet 19 is used to slide the fourth transmission gear 9 along the surface of the fourth rotating shaft 5 to move it to the top of the fourth driving gear 14, and the fourth driving gear 14 is meshed with the fourth transmission gear 9. Under the clockwise rotation of the transmission shaft 20 through the transmission of the fourth driving gear 14, the fourth driving gear 14 is meshed with the fourth transmission gear 9, thereby driving the fourth rotating shaft 5 to rotate, and driving the corresponding isolating switch to close. After the isolating switch is closed, when the fourth rotating shaft 5 does not need to be rotated, the power supply of the fourth electromagnet 19 is cut off, and the fourth transmission gear 9 is reset along the surface of the fourth rotating shaft 5 in the direction away from the fourth driving gear 14 through the fourth transmission gear 9.

[0028] When a power outage operation is required, the transmission shaft 20 rotates counterclockwise, thereby driving the connecting gear 12 arranged on its surface to rotate counterclockwise, and then the first electromagnet 16, the second electromagnet 17, the third electromagnet 18 and the fourth electromagnet 19 respectively drive the first transmission gear 6, the second transmission gear 7, the third transmission gear 8 and the fourth transmission gear 9 to move to appropriate positions according to specific usage requirements, so that the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 rotate in the opposite direction, and the corresponding isolating switch is driven to be opened under the reverse rotation of the first rotating shaft 2 and the second rotating shaft 3. After the isolating switch is opened, it is reset by the magnetic block 22.

[0029] Furthermore, one end of the transmission shaft 20 passes through the outside of one side of the fixing frame 15 , and a motor 21 for driving the transmission shaft 20 to rotate is disposed on one side of the fixing frame 15 .

[0030] The transmission shaft 20 is driven by the motor 21 to rotate the connecting gear 12 disposed on the surface thereof, thereby driving the second driving gear 11 to mesh with the third driving gear 13 .

[0031] Furthermore, the first driving gear 10 is meshed with the second driving gear 11 , the third driving gear 13 is meshed with the fourth driving gear 14 , and the connecting gear 12 is meshed with the second driving gear 11 and the third driving gear 13 .

[0032] The second driving gear 11 meshes with the first driving gear 10, the third driving gear 13 meshes with the fourth driving gear 14, and the connecting gear 12 meshes with the second driving gear 11 and the third driving gear 13, so that the first driving gear 10, the second driving gear 11, the third driving gear 13 and the fourth driving gear 14 rotate synchronously under the drive of the connecting gear 12.

[0033] Furthermore, grooves are provided on the surfaces of the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 at intervals around and inwardly concave, and the first transmission gear 6, the second transmission gear 7, the third transmission gear 8 and the fourth transmission gear 9 are slidingly connected to the first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 respectively through the grooves.

[0034] In this embodiment, the inner wall surfaces of the first transmission gear 6, the second transmission gear 7, the third transmission gear 8 and the fourth transmission gear 9 are all provided with protrusions that are slidably connected to the grooves, so as to ensure that the sliding and the corresponding first rotating shaft 2, the second rotating shaft 3, the third rotating shaft 4 and the fourth rotating shaft 5 can be driven to rotate through the protrusions, thereby ensuring axial sliding along the shaft without relative rotation with the shaft.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
