[0001] The present application relates to the field of circuit breakers, in particular to a device for replacing a live pluggable controller. BACKGROUND

[0002] In recent years, there has been a demand for a live pluggable controller in the main circuit of a circuit breaker. For example, a Chinese patent application CN111968888A discloses a plug-and-play pluggable controller and a lock-equipped circuit breaker. In actual use, the pluggable controller is usually replaced manually, which is very dangerous and poses a great safety hazard. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art and provides a device for replacing a live pluggable controller, which replaces the traditional manual replacement and improves the safety of live operation.

[0004] The object of the present application can be achieved by the following technical solutions:

[0005] A device for replacing a live pluggable controller, comprising a fixed support, a first side plate, a second side plate, a bottom plate, an electric screwdriver, a hydraulic claw, and a hydraulic push rod. The fixed support is wrapped around the periphery of the circuit breaker. The first side plate is installed on the fixed support and located directly in front of the pluggable controller on the circuit breaker. The electric screwdriver and the hydraulic claw are distributed on the first side plate. The tool end of the electric screwdriver is aligned with the bolt of the pluggable controller. The hydraulic claw is aligned with the handle of the pluggable controller. The second side plate is installed on the fixed support and located on one side of the circuit breaker. The hydraulic push rod is installed on the second side plate. The bottom plate is installed on the fixed support below the circuit breaker. The bottom plate is provided with an L-shaped slot, one end of which points to the circuit breaker and extends to the edge of the bottom plate, and the other end points to the second side plate. The bottom of the pluggable controller is provided with an adapter for embedding in the L-shaped slot.

[0006] Further, the fixed support comprises an upper support frame, a lower support frame, and a vertical rod. The upper and lower ends of the vertical rod are connected to the upper and lower support frames, respectively, by bolts. The bottom plate is installed on the lower support frame.

[0007] Further, the fixed support is provided with a positioning pin shaft, and the first side plate or the second side plate is provided with a positioning hole. When the fixed support and the first side plate or the second side plate are connected, the positioning pin shaft passes through the positioning hole for positioning.

[0008] Further, a controller is provided, which is connected to the electric screwdriver, the hydraulic claw, and the hydraulic push rod by wire or wirelessly.

[0009] Furthermore, it also includes a replaceable pluggable controller, the adapter of which is embedded in the L-shaped groove of the base plate and located at the end of the L-shaped groove pointing towards the second side plate.

[0010] Furthermore, the electric screwdriver is equipped with a telescopic motor at its tail end, and is mounted on the first side plate via the telescopic motor.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a device for replacing a powered pluggable controller, including a fixed bracket 1, a first side plate 2, a second side plate 3, a base plate 4, an electric screwdriver 5, a hydraulic claw 6, and a hydraulic push rod 7.

[0032] The fixed bracket 1 includes an upper bracket frame 11, a lower bracket frame 12, and a vertical rod 13, such as Figure 3 As shown. The upper and lower ends of the vertical rod 13 are bolted to the upper support frame 11 and the lower support frame 12, respectively. Both the upper support frame 11 and the lower support frame 12 are U-shaped. The horizontal rods on both sides of the upper support frame 11 and the lower support frame 12 are installed on both sides of the circuit breaker 8, and the upper and lower horizontal rods are connected by a vertical rod 13 to form a frame structure. The lower support frame 12 is located below the circuit breaker 8, thus the frame structure forms a semi-enclosed layout for the circuit breaker 8. The fixed bracket 1 can be directly fixed to the wall where the circuit breaker 8 is located, or it can be fixed to the low-voltage cabinet door where the circuit breaker 8 is located. When the cabinet door is closed, the fixed bracket 1 surrounds the circuit breaker 8.

[0033] The first side plate 2 is installed on the front of the circuit breaker 8 and is connected to the upper bracket frame 11 and the lower bracket frame 12 respectively. For example... Figure 4 As shown, multiple electric screwdriver mounting holes 22 and one hydraulic claw mounting hole 23 are distributed on the first side plate 2. The specific distribution of the electric screwdriver mounting holes 22 and the hydraulic claw mounting holes 23 can be changed according to the position of the bolt and handle of different models of pluggable controllers 9. The cutting end of the electric screwdriver 5 is aligned with the bolt of the pluggable controller 9, and the hydraulic claw 6 is aligned with the handle of the pluggable controller 9. Positioning holes 21 are also distributed on the first side plate 2, and positioning pins 14 are distributed on the inner sides of the upper bracket frame 11 and the lower bracket frame 12, such as... Figure 5 As shown. When the first side plate 2 is installed, the positioning pin 14 is inserted into the positioning hole 21 to provide positioning and prevent mistaken installation, simplifying the installation process. The first side plate 2 and the fixing bracket 1 are bolted together, with the bolts passing through the side of the first side plate 2.

[0034] like Figure 6 As shown, the electric screwdriver 5 adopts existing mature technology, and its tail end is fixed to the first side plate 2 by a flange 51 and bolts. The electric screwdriver 5 has a Phillips head and can rotate and extend. In another embodiment, the electric screwdriver 5 can be a simpler existing screwdriver with only rotation function. In this embodiment, a telescopic motor is set on the first side plate 2, and the electric screwdriver 5 is connected to the first side plate 2 through the telescopic motor to realize the advancement work.

[0035] like Figure 7 As shown, the hydraulic claw 6 adopts existing mature technology and is generally driven by a hydraulic cylinder. It consists of hydraulic cylinder, jaw plate, connecting column, bucket ear plate, bucket ear sleeve, bucket teeth, tooth seat and other parts. It can be extended and retracted by pulling the handle of the pluggable controller 9. The specific structure will not be elaborated here.

[0036] The second side plate 3 is mounted on the bracket and located on one side of the circuit breaker 8, connecting the upper bracket frame 11 and the lower bracket frame 12 respectively. In this embodiment, it is installed on the right side of the circuit breaker 8. A hydraulic push rod 7 is installed on the second side plate 3. Positioning holes 21 can also be provided on the edge of the second side plate 3 for engaging with the positioning pins 14 on the fixed bracket 1, improving installation convenience.

[0037] like Figure 8 As shown, the base plate 4 is mounted on the bracket below the circuit breaker 8, specifically on the lower bracket frame 12. An L-shaped groove 41 is provided on the base plate 4, one end of which points towards the circuit breaker 8 and extends to the edge of the base plate 4, while the other end points towards the second side plate 3. The bend of the L-shape is smoothly rounded. An adapter 91 is installed at the bottom of the pluggable controller 9, such as... Figure 9As shown in the figure. The adapter 91 is used to be embedded in the L-shaped groove 41 to form a movement limit for the pluggable controller 9. The adapter 91 can be in two pairs of symmetrical shapes, such as a "convex" shape, so that when the pluggable controller 9 slides along the L-shaped groove 41, its front is always perpendicular to the radial line of the L-shaped groove 41.

[0038] This embodiment further includes a controller, which is connected to each electric screwdriver 5, hydraulic claw 6 and hydraulic push rod 7 by wired or wireless means to achieve remote control by the user. The wireless connection method adopts conventional connection methods such as Bluetooth and wifi.

[0039] In this embodiment, a protective shell can also be included, and the protective shell can include the entire fixing bracket 1 and the circuit breaker 8 to comprehensively strengthen the safety protection.

[0040] The working principle of this embodiment is as follows:

[0041] Install the device: Install the fixing bracket 1 outside the circuit breaker 8, and then select the first side plate 2, the second side plate 3 and the bottom plate 4 with matching models. Install the electric screwdriver 5 and the hydraulic claw 6 on the first side plate 2, and install the first side plate 2 on the fixing bracket 1 through bolts. Then, install the bottom plate 4 at the bottom of the fixing bracket 1, and note that at this time, the end of the L-shaped groove 41 extending to the edge fits the bottom adapter 91 of the pluggable controller 9 inside the circuit breaker 8. Finally, install the second side plate 3 with the hydraulic push rod 7 installed on it on the fixing bracket 1 through bolts.

[0042] As Figure 10 shown, the specific use is to perform two-step operations through the controller:

[0043] The first step: Grab the handle on the pluggable controller 9 through the hydraulic claw 6 on the first side plate 2, and use the cross electric screwdriver 5 after positioning to counterclockwise unscrew the bolt fixing the pluggable controller 9. At the same time, the hydraulic claw 6 contracts and grabs the pluggable controller 9 and retreats, and finally pulls out the old pluggable controller 9 from the circuit breaker 8, and then manually takes it out to achieve the disassembly purpose.

[0044] The second step, the hydraulic push rod 7 on the second side plate 3 pushes the pre-installed replacement pluggable controller 9. The pre-installed replacement pluggable controller 9 is installed on the L-shaped groove 41 and slides along the L-shaped groove 41 to the front end of the installation position under the push of the hydraulic push rod 7. Then the electric screwdriver 5 extends forward, and while pushing the pluggable controller 9, tightens the bolt with a preset value on the pluggable controller 9 clockwise, and finally achieves the installation purpose.

[0045] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
