DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0028] In order to solve the problem in the prior art that the manual isolating switch 1 and the electric isolating switch cannot be transformed into each other, Figure 1 As shown, this embodiment proposes a quickly assembled modular electric disconnect switch, which is modified based on the manual disconnect switch 1.

[0029] like Figure 2 As shown, specifically, the manual disconnector 1 includes a contact system 25 and a manual operating mechanism 5 located on the top of the contact system 25. In the manual disconnector 1, the manual operating mechanism 5 includes two micro switch modules 2 and a crank 18 located between the micro switch modules 2. A cover 3 is installed on the top surface of the manual operating mechanism 5. The cover 3 serves as an appearance part. The cover 3 is connected to the manual operating mechanism 5 by four screws 4 to fix the cover 3.

[0030] like Figure 3 As shown, the micro switch module 2 includes a micro switch 11, a slide plate 10 located at one side of the micro switch 11, and a terminal block 7 located at the top of the micro switch 11. The slide plate 10 is used to trigger the micro switch 11, and the micro switch 11 is used to output a position signal.

[0031] like Figure 4 As shown, in the manual disconnector 1, there is a boss shaft 12 in the middle of the manual operating mechanism 5, and the manual operating mechanism 5 also has two groups of compression springs 13 and connecting rods 14 inside, wherein the compression spring 13 is sleeved on the outside of the connecting rod 14, the compression spring 13 stores and releases energy, and the connecting rod 14 plays a guiding role to stabilize the compression spring 13. The boss shaft 12 transmits the torque on the crank 18 to the rotating block 15, and uses the cam principle to push the slide plate 10 to move and trigger the micro switch 11. The two micro switch modules 2 and the two groups of compression springs 13 and connecting rods 14 generally form a cross-shaped layout.

[0032] like Figure 5 As shown, a rotating block 15 is arranged at the lower part of the boss rotating shaft 12, and two tubular sockets are arranged at the top of the boss rotating shaft 12. A cylindrical pin 16 is arranged at one end of the compression spring 13 close to the boss rotating shaft 12, and the cylindrical pin 16 is inserted into the corresponding socket. A rotating shaft 17 is connected to the top of the boss rotating shaft 12, and the rotating shaft 17 is connected to the crank 18. The rotating block 15 transmits the torque on the crank 18 to the contact system 25, and the cylindrical pin 16 connects the boss rotating shaft 12, the rotating shaft 17 and the connecting rod 14, and the rotating shaft 17 transmits the torque on the crank 18 to the boss rotating shaft 12.

[0033] When the crank 18 is rotated clockwise, the crank 18 drives the shaft 17 to rotate. At this time, the shaft 17, the connecting rod 14 and the boss shaft 12 are all connected to the cylindrical pin 16, so the shaft 17, the connecting rod 14 and the boss shaft 12 act at the same time. At this time, the compression spring 13 is compressed to store energy. After rotating a certain angle, the mechanism passes the dead point position. At this time, the compression spring 13 is released, the mechanism reaches the closing position, and the disconnector is closed. The opening crank 18 rotates counterclockwise, and the rest is the same.

[0034] The above is the basic structure and operation principle of the manual disconnector 1. The quick-assembly modular electric disconnector proposed in this embodiment is modified based on the above manual disconnector 1.

[0035] like Figure 6-Figure 9 As shown, Figure 1 Remove the cover 3 and screws 4 in the manual operating mechanism 5 of the manual isolating switch 1. If the manual isolating switch 1 has no auxiliary contacts, two micro switch modules 2 need to be installed; if the auxiliary contacts of the manual isolating switch 1 are two normally open and two normally closed, one micro switch module 2 needs to be installed; if the auxiliary contacts of the manual isolating switch 1 are four normally open and four normally closed, there is no need to install a micro switch module 2, and this step can be ignored. Insert the terminal head 8 on the electric module 6 into the terminal seat 7 of the micro switch module 2. Tighten the additional screws 9. Through the above 4 steps, the manual isolating switch 1 is converted into an electric isolating switch.

[0036] like Figure 7 As shown, in this embodiment, the electric module 6 includes a terminal head 8, and the terminal head 8 is connected to the circuit board 19 inside the electric module 6 through a cable. The terminal head 8 is used to cooperate with the terminal seat 7 on the micro switch module 2 for plugging.

[0037] like Figure 8 and Fig. 9As shown, in this embodiment, a crank input gear 20 is installed outside the crank 18, and the crank input gear 20 is a toothed cone toothed disc. In this embodiment, since the rotation range of the crank input gear 20 is limited, a partial toothed cone toothed disc is used. In the drive mechanism, a housing is mounted outside the motor 22, and the power end of the motor 22 is connected to the motor output gear 21, which is also a bevel gear. The motor output gear 21 meshes with the crank input gear 20 to form a power connection. An electric isolating switch handle 23 is installed outside the housing 24. The crank input gear 20 connects the crank 18 and transmits the torque of the motor 22. The motor output gear 21 connects the motor 22 and meshes with the crank input gear 20. The motor 22 outputs torque. After the electric control system of the electric isolating switch fails, the electric isolating switch handle 23 can be used to manually reach the opening and closing of the isolating switch. The housing 24 uses a buckle to fix the electric isolating switch handle 23.

[0038] After the manual disconnector 1 is modified, after the motor 22 receives the external closing control signal, the motor 22 rotates, driving the motor output gear 21 to rotate, and the motor output gear 21 is meshed with the crank input gear 20. At this time, the crank input gear 20 rotates, thereby driving the crank 18 to rotate, and the mechanism reaches the closing position, and the disconnector is closed. After closing, the boss shaft 12 pushes the slide plate 10 to trigger the microswitch 11, and the microswitch module 2 transmits the position signal to the circuit board 19, and the motor 22 stops rotating. The closing process ends here. The opening crank 18 rotates counterclockwise, and the rest is the same. After the electric control fails, the electric module 6 is equipped with an electric disconnector handle 23, which can be inserted into the square hole of the crank 18, and the opening and closing can be completed by rotating it forcefully.

[0039] It should be noted that, in the description of the present utility model, unless otherwise specified, the meaning of "multiple" is two or more; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.
