Detailed Implementation

[0019] like Figure 1 The 10kV handcart switch auxiliary opening and closing operation mechanism shown includes a telescopic bracket 2 and an electric push rod 1. The telescopic bracket 2 has connectors at both ends that can be detachably connected to the upper and lower ends of the switchgear handcart compartment A. The electric push rod 1 is detachably mounted on the telescopic bracket 2 through a detachable connector. The movable rod of the electric push rod 1 is aligned with the opening / closing button (opening button or closing button). The electric push rod 1 is wirelessly connected to the remote control transmitter 7 through a remote control receiver 5. The remote control receiver 5 starts the electric push rod 1 to automatically extend and retract to press the opening button or closing button according to the received remote control signal. When the switch control power supply or remote control system fails, the electric push rod 1 is placed at the front of the switch cabinet's handcart compartment A using a telescopic bracket supported between the upper and lower ends of the compartment A. The movable rod of the electric push rod 1 is aligned with the open / close button (open or close button). Then, the remote transmitter sends a command to the remote receiver to control the movement of the electric push rod, causing the movable rod of the electric push rod 1 to press the open / close button, thus achieving remote opening and closing operations. This avoids the personal safety risks of manual on-site opening and closing operations and saves the time cost wasted on repairing faults and then performing opening and closing operations.

[0020] According to one embodiment of this application, the telescopic support 2 includes an outer rod 21, a first inner rod 22, and a second inner rod 23. The first inner rod 22 is axially slidably connected to one end of the outer rod 21, and the second inner rod 23 is axially slidably connected to the other end of the outer rod 21. By setting the first inner rod 22 and the second inner rod 23, which are axially slidably connected to the outer rod 21, not only can the length of the telescopic support be adjusted to adapt to the height of the upper and lower ends of the switchgear truck compartment A, ensuring the support stability of the telescopic support 2, but the height of the electric push rod 1 can also be adjusted by adjusting the second inner rod 23, which is located below the outer rod 21, according to the open / close button. The telescopic support 2 uses an adjustable stainless steel bracket, with a telescopic adjustment range between 500mm and 1000mm, meeting the requirements of all current mainstream 10kV truck switchgear models.

[0021] According to one embodiment of the present application, the outer rod 21 is provided with a first screw bolt 221 at the end connected with the first inner rod 22, and the first inner rod 22 is fastened by the first screw bolt 221 extending into the inner part of the outer rod 21. The outer rod 21 is provided with a second screw bolt 231 at the end connected with the second inner rod 23, and the second inner rod 23 is fastened by the second screw bolt 231 extending into the inner part of the outer rod 21. When adjusting the length of the telescopic support 2, first, the length of the second inner rod 23 is adjusted according to the position of the opening / closing button, and then the length of the first inner rod 22 is adjusted according to the height of the upper and lower ends of the switch cabinet handcart room A. After the lengths of the first inner rod 22 and the second inner rod 23 are adjusted, the screw bolts are screwed to fasten the inner rods in the outer rod 21.

[0022] According to one embodiment of the present application, the connector is an electromagnet 3. When the length of the telescopic support 2 is adjusted, the electromagnet is powered to generate a magnetic force to be adsorbed to the upper and lower ends of the switch cabinet, thereby playing a role of a fixing mechanism, and the magnetic force can be adjusted to meet the magnetic force requirements of different scenes.

[0023] According to one embodiment of the present application, as shown in Figure 2 the outer rod 21 is provided with a connecting block 211; the detachable connecting piece includes a clamp 4, the clamp 4 includes two oppositely arranged clamp bodies, one side of one of the clamp bodies away from the electric push rod 1 is provided with a U-shaped clamp 41 matched with the connecting block 211, and the connecting block 211 is clamped in the U-shaped clamp 41 and then fixed together by a fastener. By using the detachable connecting piece, the electric push rod can be conveniently installed, disassembled and stored.

[0024] According to one embodiment of the present application, the end of the movable rod of the electric push rod 1 facing the pressing head 11 matched with the opening / closing button is provided with a laser, the end of the pressing head 11 facing the circuit breaker is provided with a light transmission hole arranged along the light path of the laser, and the light path of the laser is located at the axis of the pressing head 11. By arranging the laser in the pressing head 11, when adjusting the position of the electric push rod 1, the electric push rod 1 does not need to be excessively close to the opening / closing button, and the laser can be used for accurate positioning.

[0025] According to one embodiment of the present application, the inner side of the end of the light transmission hole facing the circuit breaker is provided with a transparent window. The transparent window uses a lens that can transmit laser, the transparent window should be arranged on the inner side of the light transmission hole, and the transparent window is sealingly connected with the shell of the pressing head 6, thereby achieving waterproof and dustproof protection for the internal laser.
