The speed and the range of the switch operating mechanism are adjusted, so that the speed and the range of the switch can be accurately controlled, the phenomenon that the switch operating mechanism is too slow to be switched or is not switched in place to generate heat or even burn the switch is avoided, and the service life of the switch is prolonged. The execution data also comprises the driving force of the first driving piece, and different knife switches correspond to the driving force of different first driving pieces so as to drive the pulling-in and pulling-out of different knife switches. In the pulling-closing process, the first support 221 can move at a uniform speed by controlling the magnitude of the driving force, so that the stability of the disconnecting link in the pulling-closing process is improved.

Optionally, the determining module is further configured to receive the first relative position information and the second relative position information. The judging module can send a first instruction according to the first relative position information, the second relative position information and the initial action data to enable the guide rail 21 and the operating element 222 to respectively reach a first preset position and a second preset position, so that the operating element 222 is fixed on the disconnecting link operating mechanism to prepare for opening or closing the disconnecting link. The determining module can also send a second command to the first driving member to drive the first support 221 to slide, so that the first support 221 drives the operating member 222 to open or close the knife switch through the telescopic rod 223. The relative positioning of the guide rail 21, the operating element 222 and the disconnecting link operating mechanism and the switching process of the disconnecting link operating mechanism are controlled by the instruction sent by the judging module, the control is accurate, the operation is simple, the condition that the switching is too slow or the switching is not in place due to manual operation is avoided, and the service life of the disconnecting link is prolonged.

Preferably, as shown in fig. 1, the guide rail 21 is a circular arc-shaped guide rail that opens toward the operating element 222, and the circular arc-shaped guide rail is provided on the multi-degree-of-freedom robot arm 12 so as to be angularly adjustable. Although the sizes and structures of the different types of disconnecting links are different, the movement track of the disconnecting link operating mechanism of each disconnecting link in the pulling-in process is a part of a circle, namely an arc. Therefore, the guide rail 21 is designed to be a circular arc-shaped guide rail, the operating element 222 is located in the opening direction of the circular arc-shaped guide rail, the rotating radius of the operating element 222 can be adjusted by adjusting the distance between the operating element 222 and the circular arc-shaped guide rail, so that the rotating radius of the operating end of the operating element 222 is the same as the rotating radius of the knife gate operating mechanism, the operating element 222 can open or close the knife gate operating mechanisms with different rotating radii by sliding the first bracket 221 on the circular arc-shaped guide rail, and the first bracket 221 cannot be jammed with the circular arc-shaped guide rail in the movement process of the operating element 222. The arc-shaped guide rail is angularly adjustably disposed on the multi-degree-of-freedom mechanical arm 12, and illustratively, the arc-shaped guide rail is rotatably connected to the second rotating arm 122. When the second rotating arm 122 is horizontal, the arc-shaped guide rail can rotate around the x-axis direction, and in combination with five degrees of freedom of movement realized by the base 11 and the multi-degree-of-freedom mechanical arm 12, the device can realize the adjustment of the arc-shaped guide rail in the directions of six degrees of freedom, so as to adjust the direction of the arc-shaped guide rail moving relative to the disconnecting link operating mechanism, and make the extending direction of the arc-shaped guide rail parallel to the movement track of the disconnecting link operating mechanism in the opening and closing process, thereby making the rotation track of the operating end of the operating part 222 coincide with the rotation track of the disconnecting link operating mechanism.

Alternatively, in the cross section of the extending direction of the guide rail 21, one of the first bracket 221 and the guide rail 21 has a T-shaped protrusion in cross section, and the other one has a C-shaped groove in cross section, and the T-shaped protrusion is slidably disposed on the C-shaped groove. In this embodiment, in a cross section in the extending direction of the circular arc-shaped guide rail, the cross section of the first bracket 221 is a C-shaped groove, the cross section of the circular arc-shaped guide rail is a T-shaped protrusion, and a "-" portion of the T-shaped protrusion is slidably disposed in the C-shaped groove, so that the first bracket 221 can slide along the extending direction of the circular arc-shaped guide rail without departing from the circular arc-shaped guide rail. The I part of the T-shaped protrusion extends out of the C-shaped groove and is rotatably connected to the second rotating arm 122, so that the angle and the position of the arc-shaped guide rail can be adjusted through the base 11 and the multi-degree-of-freedom mechanical arm 12.

Optionally, the operating assembly 22 further comprises a first gear 2212, a plurality of first teeth are disposed on the first gear 2212, a plurality of second teeth 211 are disposed on the guide rail 21, and a plurality of the plurality of first teeth are engaged with a plurality of the plurality of second teeth 211; a first driving member and/or a first gear 2212 are disposed on the first bracket 221, and an output end of the first driving member can drive the first gear 2212 to rotate so as to drive the first bracket 221 to slide along the guide rail 21. By controlling the position of the operating assembly 22 relative to the guide rail 21 in a geared manner, the following effects can be achieved: the instantaneous transmission ratio of gear transmission is constant, and the stability of the switch operating mechanism is high; the transmission power range of gear transmission is large, the bearing capacity is high, and the large-scale disconnecting link operating mechanism can be pulled and closed; the gear transmission speed range is large, so that the gear transmission device is suitable for different types of disconnecting links and avoids over-slow pulling and closing; the precision of the gear transmission is high, which facilitates accurate adjustment of the position of the operating member 222 relative to the guide rail 21.

Illustratively, as shown in fig. 2 to 4, a first gear 2212 is rotatably disposed in the C-shaped groove of the first bracket 221, a plurality of second teeth 211 are disposed at equal intervals on a "-" portion of the T-shaped protrusion of the guide rail 21, and when the T-shaped protrusion is slidably disposed in the C-shaped groove, a plurality of first teeth of the first gear 2212 are engaged with the plurality of second teeth 211. A first driving member (not shown) is fixed on the first bracket 221, and an output end of the first driving member is connected to the first gear 2212, and can drive the first gear 2212 to rotate, so that the first gear 2212 rolls along each second tooth 211, thereby driving the first bracket 221 to slide along the arc-shaped guide rail, and further driving the operating member 222 to open or close the switch operating mechanism. Optionally, a roller 2211 is disposed at a joint of the C-shaped groove of the first bracket 221 and the T-shaped protrusion of the guide rail 21, and the first bracket 221 slides relative to the guide rail 21 through the roller 2211, so as to reduce wear, reduce sliding resistance, and improve durability of the first bracket 221 and the guide rail 21.

Specifically, as shown in fig. 4, one end of the first rod 2231 is fixed on the first bracket 221, the second rod 2232 is slidably disposed on the other end of the first rod 2231 along the length direction, and a second driving member (not shown in the figure) is disposed on the operating assembly 22, and is communicatively connected to the control unit and capable of driving the second rod 2232 to slide relative to the first rod 2231 so as to adjust the distance between the operating member 222 and the circular arc-shaped guide rail. Also, the second driver can lock the relative movement of the second rod 2232 and the first rod 2231 when the operating member 222 reaches the second preset position. The first rod 2231 and the second rod 2232 are both rigid rods to stably transmit the movement of the first bracket 221 to the operating element 222, so that the deviation of the movement track of the operating element 222 caused by the deviation of the positioning of the operating element 222 is avoided, and the switch can not be pulled.
