[0023] 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.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] Please refer to the attached Figure 1-4 The present invention provides a quickly disassembled and assembled high-voltage disconnect switch manual operating mechanism 100. The high-voltage disconnect switch manual operating mechanism 100 includes a main component module 200, a main shaft body 300, a manual operating handle 400, an electromagnetic lock module 500, a mechanism box 600, an auxiliary switch module 700, a heating module 800, and a terminal block module 900.

[0027] The main component module 200 is detachably connected to the top of the mechanism box 600. It should be understood that the specific shape of the main component module 200 can be designed according to actual needs. In this embodiment, the main component module 200 is configured as a rectangular parallelepiped and is detachably connected to the top of the mechanism box 600. The side of the main component module 200 is further provided with a side plate 210 for connecting other components. The detachable connection method includes but is not limited to one or more of a threaded connection, a snap connection, and a hinge connection. Preferably, a bolt connection is adopted in this embodiment.

[0028] The main shaft body 300 is movably connected to the top of the main component module 200. The top of the main shaft body 300 is connected to a connecting rod 310, and a first slot 320 is provided on one side of the connecting rod 310. Specifically, the main shaft body 300 is movably connected to the top of the main component module 200, and the bottom of the main shaft body 300 passes through the main component module 200 and extends into the interior of the mechanism box 600. In this embodiment, the main shaft body 300 is located in the middle of the main component module 200, and the main shaft body 300 can rotate in the horizontal direction. The top of the main shaft body 300 is fixedly connected to a connecting rod 310, which is vertically upward. The connecting rod 310 is used to connect a high-voltage disconnector (not shown). At the same time, a first slot 320 is provided on one side of the bottom of the connecting rod 310. The first slot 320 and the main shaft body 300 are integrated, and the slot is vertically upward.

[0029] The bottom of the manual operating handle 400 is movably connected to the first slot 320. It is worth noting that the bottom of the manual operating handle 400 is matched with the first slot 320, and the bottom of the manual operating handle 400 is movably connected to the first slot 320. The manual operating handle 400 can rotate in the vertical direction. When the angle between the manual operating handle 400 and the main component module 200 is 0 degrees, the manual operating handle 400 can drive the main shaft body 300 to rotate on the main component module 200 to complete the opening and closing of the disconnector (not shown in the figure); when the manual operating handle 400 forms a 90-degree angle with the main component module 200, the bottom of the manual operating handle 400 will be stuck in the slot (not shown in the figure) of the main component module 200 for positioning and fixing.

[0030] The electromagnetic lock module 500 is detachably connected to the main component module 200 via a mounting member 520, and the auxiliary switch module 700, the heating module 800, and the terminal block module 900 are detachably connected to the interior of the mechanism box 600. It should be understood by those skilled in the art that the mounting member 520 is detachably connected to the side panel 210 on the main component module 200, and the electromagnetic lock module is detachably connected to the main component module 200 via the mounting member 520. The electromagnetic lock module 500 is used to lock the opening and closing positions and can only be unlocked under conditions where operation is permitted, so as to perform opening and closing operations of the disconnector, thereby avoiding erroneous operations when operation is not permitted. The interior of the mechanism box 600 is detachably connected to the auxiliary switch module 700, the heating module 800, and the terminal block module 900 in sequence from top to bottom. In this embodiment, they are all connected and fixed using bolts, which facilitates disassembly and installation.

[0031] Furthermore, the auxiliary switch module 700 includes an auxiliary switch body 710, a central shaft 730, a rotary joint 720 and a contact 740 for completing the switching between the open position and the closed position; the rotary joint 720 is connected to the bottom of the main shaft body 300 and is located inside the mechanism box 600, the central shaft 730 is connected to the bottom of the rotary joint 720, and the bottom of the central shaft 730 is connected to the auxiliary switch body 710. It is worth noting that the auxiliary switch module 700 consists of an auxiliary switch body 710, a central shaft 730, a rotating joint 720 and a contact 740. The bottom of the main shaft body 300 passes through the main component module 200 and extends into the mechanism box 600. The top of the rotating joint 720 is engaged with the bottom of the main shaft body 300. The bottom of the main shaft body 300 extends into the groove at the top of the rotating joint 720, thereby driving the rotating joint 720 to rotate. The top of the central shaft 730 is fixedly connected to the bottom of the rotating joint 720. The bottom of the central shaft 730 is connected to the auxiliary switch body 710. When the main shaft body 300 rotates, it drives the rotating joint 720 to rotate, and then drives the central shaft 730 to rotate, and then the contact 740 on the auxiliary switch body 710 completes the switching of the open position or the closed position.

[0032] As a preferred embodiment of the present invention, the heating module 800 includes a temperature and humidity controller 810 and a heating block 820, and both the temperature and humidity controller 810 and the heating block 820 are detachably connected to the interior of the mechanism box 600. It should be understood that in this embodiment, the temperature and humidity controller 810 and the heating block 820 are both bolted to the interior of the mechanism box 600. When the temperature inside the mechanism box 600 is low or the humidity is high, the temperature and humidity controller 810 starts and turns on the power supply of the heating block 820 to heat and dehumidify the box, thereby avoiding affecting the normal operation of the mechanical moving parts when the temperature is low or the humidity is high.

[0033] Please refer again to the attached Figure 1-4 The electromagnetic lock module 500 includes an electromagnetic lock 510, a mounting member 520, and a lock card 530. The mounting member 520 is detachably connected to the top of the main component module 200, the electromagnetic lock 510 is detachably connected to the top of the mounting member 520, and the lock card 530 is fixedly connected to the middle portion of the outer wall of the connecting rod 310. Specifically, the mounting member 520 is detachably connected to the top of the main component module 200. In this embodiment, the side of the main component module 200 is provided with a side plate 210 for connecting other components. The mounting member 520 is detachably connected to the side plate 210 of the main component module 200, the electromagnetic lock module 500 is detachably connected to the top of the mounting member 520, and the lock card 530 is fixedly connected to the middle portion of the outer wall of the connecting rod 310.

[0034] Furthermore, a post 511 protrudes from the outer wall of the electromagnetic lock 510, and second slots 531 are provided on both sides of the lock card 530 to cooperate with the post 511. It should be understood by those skilled in the art that the electromagnetic lock 510 is provided with a post 511 for locking, and two opposite sides of the lock card 530 are provided with second slots 531 to cooperate with the post 511. The second slots 531 are oriented vertically upward. When the manual operating handle 400 drives the main shaft 300 to rotate, the post 511 of the electromagnetic lock 510 will retract to ensure that the main shaft 300 can rotate smoothly. When the opening or closing operation of the disconnector is completed, the electromagnetic lock 510 extends the post 511 to the second slot 531 of the lock card 530 to lock it, ensuring that the main shaft 300 cannot rotate and preventing misoperation.

[0035] As a preferred embodiment of the present invention, the terminal block module 900 is electrically connected to the auxiliary switch module 700 via a flat cable 910. It should be understood that both the terminal block module 900 and the auxiliary switch module 700 can be detachably connected to the interior of the mechanism box 600. The terminal block module 900 is electrically connected to the auxiliary switch module 700 via the flat cable 910, which allows for faster assembly and disassembly of the terminal block module 900 and the auxiliary switch.

[0036] As a preferred embodiment of the present invention, the manual operating mechanism is connected to the isolating switch via the connecting rod 310. Specifically, the connecting rod 310 is fixedly connected to the top of the main shaft body 300, and the connecting rod 310 can serve as a component for connecting the isolating switch.

[0037] Furthermore, the manual operating handle 400 has a rotational freedom of 0 to 90 degrees, the main shaft body 300 has a rotational freedom of 0 to 180 degrees, and the rotary joint 720 and the central shaft 730 have a rotational freedom of 0 to 180 degrees, which are used to complete the opening and closing of the disconnector. It is worth noting that the rotational freedom of the manual operating handle 400, the main shaft body 300, and the central shaft 730 can be set according to actual needs. Preferably, in this embodiment, the manual operating handle 400 can rotate 0 to 90 degrees in the vertical direction, and when the manual operating handle 400 is in the horizontal direction, it can drive the main shaft body 300 to rotate together, thereby driving the rotation of the rotary joint 720 and the central shaft 730 to complete the opening and closing of the disconnector.

[0038] The working process of this embodiment: please refer to Figure 1-4When the disconnector is closed, the manual operating handle 400 is pulled until it is parallel to the main shaft 300, rotating the main shaft 300 90 degrees clockwise. This in turn drives the disconnector through the connecting rod 310. The lower end of the main shaft 300 rotates the rotating joint 720, which in turn rotates the central shaft 730, causing the contact 740 on the auxiliary switch body to switch, generating a closed position signal. When the disconnector is opened, the main shaft 300 rotates 90 degrees counterclockwise.

[0039] The process of quick disassembly and assembly of the manual operating mechanism is as follows. It should be noted that in this embodiment, the detachable connection method adopted is bolt connection, which is convenient for disassembly and assembly.
