[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figures 1-10 The CNC mechanism box of the disconnect switch shown includes a box 2 with a corrosion-resistant coating. A drive mechanism 5 is installed inside the box 2. The drive mechanism 5 includes a servo motor 501 fixedly connected inside the box 2, which has high control precision and can achieve accurate speed and revolution control. An electric telescopic rod 502 is fixedly connected to the output end of the servo motor 501, which can perform precise distance control. The movable end of the electric telescopic rod 502 is fixedly connected to a spline shaft 504 through a retaining ring 503. A driven bevel gear 4 with a vertical axis is rotatably connected to the top of the box 2. A longitudinal shaft hole 204 is opened on the top of the box 2 for cooperating with the shaft of the driven bevel gear 4 to form a rotating pair. The lower end of the driven bevel gear 4 has a coaxial end shaft 401. A spline hole 402 is opened on the lower end face of the end shaft 401, which is exactly inserted with the spline shaft 504 to achieve synchronous rotation. At the same time, the spline shaft 504 and the end shaft 401 form a simple clutch structure.

[0031] A coaxial screw 6 is fixedly connected to the top surface of the driven bevel gear 4. A lifting arm 7 is slidably connected to the top of the housing 2. The lifting arm 7 is threadedly engaged with the screw 6. The lifting arm 7 can convert the rotational motion of the screw 6 into its own lifting motion. A vertical guide frame 207 is fixedly connected to the upper surface of the housing 2. The lifting arm 7 includes a screw sleeve 701 that is threadedly engaged with the screw 6. The outer side of the screw sleeve 701 has a sliding sleeve 702, which fits around the guide frame 207 to form a sliding pair. Usually, there are two combinations of guide frame 207 and sliding sleeve 702, which can effectively improve the stability of the lifting arm 7's up and down movement. The upper end of the screw sleeve 701 has a cylinder 703. The cylinder 703 fits around the screw 6 but does not contact the screw 6. It only serves to cover the screw 6. The upper end of the cylinder 703 has a hinge frame 704, which is used to cooperate with the switch in the line to form a rotating pair, thereby controlling the switch structure in the line to realize the opening and closing actions.

[0032] A horizontally axial manual bevel gear 3 is rotatably connected to the front side wall of the housing 2. The manual bevel gear 3 meshes with the driven bevel gear 4. A transverse shaft hole 203 is also provided on the front side wall of the housing 2 to cooperate with the shaft of the manual bevel gear 3 to form a rotating pair. A crank handle opening 301 is provided on the front end face of the manual bevel gear 3 to cooperate with the end of the crank handle. A groove 302 is provided on the inner wall of the crank handle opening 301 to lock the protruding structure on the side of the end of the crank handle, thereby transmitting the torque of the crank handle to the manual bevel gear 3. A screw cap 230 is also rotatably connected to the front of the housing 2. The housing 2 is used to cover the transverse shaft hole 203 and the end of the manual bevel gear 3 located in the transverse shaft hole 203. The front of the housing 2 has a fixed shaft 206. The screw cap 230 has a mating hole 232 near the side, which is exactly mated with the fixed shaft 206 to form a rotating pair. The front of the screw cap 230 also has a handle 231 away from the mating hole 232. The front of the housing 2 is also provided with a support flange 205 located below the transverse shaft hole 203, which just supports the screw cap 230, so that the screw cap 230 is aligned with the transverse shaft hole 203 and completely covers the front end of the manual bevel gear 3.

[0033] The front of the housing 2 is equipped with a mode knob 202 and an electric switch 220. The mode knob 202 is used to change the working mode of the CNC mechanism housing, while the electric switch 220 only works in specific modes. Generally, the front of the housing 2 also has markings around the mode knob 202, indicating manual, local, and remote modes, representing the three available working modes. There are usually two electric switches 220, namely a closing button 221 and a closing button 222. The two buttons cannot be pressed at the same time. If they are pressed at the same time, the commands cancel each other out and no control effect will be produced. The lifting arm 7 will not move. The housing 2 contains a waterproof box 8. The waterproof box 8 contains electrical components such as a power module, controller, and remote communication module, as well as cables connecting the various components. The mode knob 202, closing button 221, and closing button 222 are all electrically connected to the controller inside the waterproof box 8 to transmit control signals.

[0034] The front sidewall of the housing 2 is further back than the front side frame of the housing 2, which makes the front end face of the housing 2 form a concave structure. The upper and lower sidewalls of the housing 2 are movably connected to the door 1. The surface of the door 1 also has a corrosion-resistant coating. The operating handle 9, which is the crank mentioned above, is suitable for placement between the door 1 and the front side of the housing 2. The upper and lower sidewalls of the housing 2 are fixedly connected to the hinge shaft 201. The door 1 has a hinge hole 101 near the side, which is used to cooperate with the hinge shaft 201 to form a rotating pair. Therefore, the door 1 is rotated to open and close. The side of the door 1 away from the hinge hole 101 is also provided with a door lock 102, which makes the door 1 less easy to open and increases the difficulty for non-staff to operate the CNC mechanism box of the isolating switch.

[0035] Working principle: When the mode knob 202 is turned to the remote position, the cabinet door 1 can be closed and locked. During control or within the power supply station, a terminal cabinet or control panel sends a command to the controller via a remote communication module. The electric telescopic rod 502 then performs a self-check to ensure that the splined shaft 504 engages with the end shaft 401. After the self-check, the servo motor 501 drives the screw 6 to rotate via the driven bevel gear 4, which in turn moves the lifting arm 7 up and down to achieve the opening and closing action of the switch. When the mode knob 202 is turned to the nearest position, the cabinet door 1 cannot be closed, the electric telescopic rod 502 remains extended, and the splined shaft 504 remains engaged with the end shaft 401. Pressing the trip button 222 reverses the servo motor 501, causing the switch to tilt upwards, breaking the circuit. Pressing the trip button again... When the switch button 221 is turned, the servo motor 501 rotates forward, and the switch descends to connect the circuit. When the mode knob 202 is turned to the manual position, the electric telescopic rod 502 retracts, the spline shaft 504 disengages from the end shaft 401, the handle 231 is lifted, the cover 230 is lifted to expose the end of the manual bevel gear 3, and the operating handle 9 is inserted into the crank port 301. Since there is no electromagnetic resistance from the servo motor 501, it is relatively easy to turn the manual bevel gear 3, which is directly driven by the driven bevel gear 4. Since the initial position of the switch and the screw 6 is at the limit position, try turning it left or right before turning the operating handle 9, and then continue to turn it in the direction that can be turned. If clockwise rotation is closing the circuit, then counterclockwise rotation is opening the circuit.
