Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, specifically an emergency power circuit breaker device. Background Technology

[0002] An emergency power disconnect device is a device used in power systems to disconnect power in an emergency, designed to ensure the safety of power facilities and prevent the spread of faults. This device typically consists of an electrical control system, circuit breaker, and monitoring equipment. It can quickly cut off power when an abnormality or emergency occurs in the power system, preventing electrical fires, equipment damage, or other safety accidents. Its main features are fast response speed, ease of operation, and the ability to be automatically or manually triggered according to site conditions, ensuring the stability of the power system.

[0003] Conventional circuit breakers mainly achieve circuit switching by operating a rotary gate. However, in actual operation, the traditional rotary gate can be rotated directly without any limiting capability. This means that the circuit breaker can be operated directly to switch the circuit on or off whether it is in the closing or opening position, which is dangerous and has a high possibility of misoperation. Therefore, it is urgent to improve this system. Utility Model Content

[0004] The purpose of this invention is to provide an emergency power tripping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency power tripping device, comprising a tripping device body, with fixed lugs fixedly installed at both the upper and lower ends of the tripping device body, a mounting base fixedly installed at the center of the front of the tripping device body, a rotating gate movably installed inside the mounting base, the rotating gate rotating relative to the mounting base, limit holes being provided on the side of the tripping device body near the upper and lower ends, L-shaped plates being installed at both the left and right ends of the rotating gate, and fixed tubes being fixedly installed on the inner sides of the L-shaped plates, with plug-in pins provided at the relatively close ends of the two fixed tubes, the plug-in pins being adapted to the limit holes, and an operating component being installed between the two plug-in pins, wherein when the rotating gate is at its highest or lowest point, the plug-in pins are movably engaged with the upper limit hole or the lower limit hole respectively.

[0006] Before use, the device is installed using external bolts and fixing lugs. The device is in the closed or open state when the rotary gate is at its highest and lowest points.

[0007] As a further technical solution of this utility model, the inside of each fixed tube is movably fitted with a limiting plate, and a limiting rod is fixedly installed at the relatively close ends of the two limiting plates.

[0008] As a further technical solution of this utility model, a limiting spring is movably sleeved on the outer side of the limiting rod, and the left and right ends of the limiting spring are respectively connected to one end of the limiting plate and one end of the inner cavity of the fixed tube.

[0009] As a further technical solution of this utility model, the ends of the two limiting rods that are relatively far apart are connected to the plug-in post, and the end of the plug-in post that is far away from the limiting rod is provided with an arc guide surface.

[0010] As a further technical solution of this utility model, when the limiting spring is in the initial state and the plug-in post and the limiting hole correspond to each other, the plug-in post and the limiting hole are movably engaged.

[0011] When closing or opening is required, the rotary gate can be rotated to the highest or lowest position. At this time, the L-shaped plate on one side of the rotary gate rotates synchronously, driving the plug-in column to move. The plug-in column can then contact the guide slope on the front of the circuit breaker body. The guide slope applies force to the plug-in column, forcing the limit spring to be stretched. The limit plate and limit rod then move away from the plug-in column, and the plug-in column moves towards the fixed tube. When the plug-in column moves to the corresponding position with the limit hole, the limit spring automatically resets. At this time, the plug-in column and the limit hole are engaged, the device is in the closed or open state, and the position locking process of the rotary gate is completed.

[0012] By utilizing the interaction between the plug-in pin and the limit hole, and taking advantage of the rotation process of the rotary gate, the plug-in pin can automatically engage with the limit hole when the rotary gate is rotated to the correct position, completing the locking process. The entire locking process is completed automatically, meaning that the gate is automatically locked when closed and opened, avoiding misoperation, improving safety redundancy, and enhancing overall safety.

[0013] As a further technical solution of this utility model, the control component includes a control panel, and first fixed seats are fixedly installed on both the left and right sides of the bottom end of the control panel. The ends of the first fixed seats away from the control panel are movably connected to connecting rods through rotating shafts, and the ends of the connecting rods away from the first fixed seats are movably connected to second fixed seats through rotating shafts.

[0014] As a further technical solution of this utility model, an extension plate is fixedly installed at the bottom of the second fixing base, and the bottom end of the extension plate is connected to one end of the outer side of the plug-in post.

[0015] As a further technical solution of this utility model, a guide rod is fixedly installed at the bottom end of the control panel near the front side. A guide sleeve is movably sleeved at the bottom end of the guide rod, and the bottom end of the guide rod is connected to the top end of the rotary gate.

[0016] When it is necessary to release the locking state of the closed or open circuit, pressure can be applied to the control panel to move it in the direction of the rotary gate. At this time, under the guidance of the guide rod and guide sleeve, the control panel can be driven to move closer to the rotary gate. At this time, the left and right connecting rods deflect accordingly and apply a thrust to the two extension plates. The two extension plates drive the two plug-in pins to move away from each other until the plug-in pins leave the limit hole, thus releasing the lock and allowing the rotary gate to be operated.

[0017] By utilizing the cooperation between the control component and the plug-in terminal, the locking process can be quickly released with just a simple pressing action. This not only improves the safety redundancy of the device through the locking process, but also does not increase the complexity of the device operation. It can still achieve rapid closing and opening, further improving the ease of operation of the device.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) This utility model utilizes the cooperation between the plug-in post and the limit hole, and utilizes the rotation process of the rotary gate. When the rotary gate is rotated to the position, the plug-in post can automatically engage with the limit hole to complete the locking process. The entire locking process is completed automatically, that is, the automatic locking state when the gate is closed and opened, avoiding misoperation, improving safety redundancy, and improving overall safety.

[0020] (2) By utilizing the cooperation between the control component and the plug-in column, the locking process can be quickly released with only a simple pressing action. This not only improves the safety redundancy of the device through the locking process, but also does not increase the complexity of the device operation. It can still achieve quick closing and opening, further improving the ease of operation of the device. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown in the embodiment of this utility model, an emergency power tripping device includes a tripping device body 1. Fixed ear plates 2 are fixedly installed at both the upper and lower ends of the tripping device body 1. A mounting base 3 is fixedly installed in the middle of the front of the tripping device body 1. A rotary gate 4 is movably installed inside the mounting base 3, rotating relative to the mounting base 3. Limiting holes 5 are opened on the side of the tripping device body 1 near the upper and lower ends. L-shaped plates 7 are installed at both the left and right ends of the rotary gate 4. Fixed tubes 8 are fixedly installed on the inner side of the L-shaped plates 7. Insertion posts 12 are provided at the relatively close ends of the two fixed tubes 8. The insertion posts 12 are adapted to the limiting holes 5. An operating component 6 is installed between the two insertion posts 12. When the rotary gate 4 is at its highest or lowest point, the insertion posts 12 are movably engaged with the upper limiting hole 5 or the lower limiting hole 5, respectively.

[0028] Before use, the device is installed using external bolts and fixing lug 2. At the same time, when the rotary gate 4 is at its highest and lowest points, the device is in the closed or open state.

[0029] like Figure 1 and Figure 2 as well as Figure 4 As shown, the interior of the fixed tube 8 is movably fitted with a limiting plate 9. The two limiting plates 9 are fixedly installed with limiting rods 10 at their relatively close ends. The outer side of the limiting rods 10 is movably fitted with a limiting spring 11. The left and right ends of the limiting spring 11 are respectively connected to one end of the limiting plate 9 and one end of the inner cavity of the fixed tube 8. The two limiting rods 10 are connected to the insertion post 12 at their relatively far ends. The insertion post 12 is provided with an arc guide surface at the end away from the limiting rod 10. When the limiting spring 11 is in its initial state and the insertion post 12 corresponds to the limiting hole 5, the insertion post 12 and the limiting hole 5 are movably engaged.

[0030] When it is necessary to close or open the circuit, the rotary gate 4 can be rotated to the highest or lowest position. At this time, the L-shaped plate 7 on one side of the rotary gate 4 rotates synchronously and drives the plug-in post 12 to move. The plug-in post 12 can contact the guide slope on the front of the circuit breaker body 1. At this time, the guide slope can apply force to the plug-in post 12, forcing the limit spring 11 to be stretched. At this time, the limit plate 9 and the limit rod 10 move away from the plug-in post 12. At this time, the plug-in post 12 moves towards the fixed tube 8. When the plug-in post 12 moves to the corresponding position of the limit hole 5, the limit spring 11 automatically resets. At this time, the plug-in post 12 and the limit hole 5 are engaged, the device is in the closed or open state, and the position locking process of the rotary gate 4 is completed.

[0031] By utilizing the cooperation between the plug-in post 12 and the limit hole 5, and by utilizing the rotation process of the rotary gate 4, that is, when the rotary gate 4 is rotated to the position, the plug-in post 12 can automatically engage with the limit hole 5 to complete the locking process. The entire locking process is completed automatically, that is, the automatic locking state when closing and opening the gate avoids misoperation, improves safety redundancy, and improves overall safety.

[0032] like Figure 1 and Figure 3 As shown, the control assembly 6 includes a control plate 601. First fixed seats 604 are fixedly installed on both the left and right sides of the bottom end of the control plate 601. The ends of the first fixed seats 604 away from the control plate 601 are movably connected to the connecting rods 606 via a rotating shaft. The ends of the connecting rods 606 away from the first fixed seats 604 are movably connected to the second fixed seats 605 via a rotating shaft. An extension plate 607 is fixedly installed at the bottom end of the second fixed seats 605. The bottom end of the extension plate 607 is connected to one end of the outer side of the plug-in post 12. A guide rod 603 is fixedly installed at the bottom end of the control plate 601 near the front side. A guide sleeve 602 is movably sleeved at the bottom end of the guide rod 603. The bottom end of the guide rod 603 is connected to the top end of the rotary gate 4.

[0033] When it is necessary to release the locked state of the gate being closed or opened, pressure can be applied to the control plate 601 to move it toward the rotary gate 4. At this time, under the guidance of the guide rod 603 and the guide sleeve 602, the control plate 601 can be driven to move toward the rotary gate 4. At this time, the left and right connecting rods 606 deflect accordingly and apply a pushing force to the two extension plates 607. The two extension plates 607 also drive the two plug-in pins 12 to move away from each other until the plug-in pins 12 leave the limit hole 5, thus releasing the lock and allowing the rotary gate 4 to be operated.

[0034] By utilizing the cooperation between the control component 6 and the plug-in post 12, the locking process can be quickly released with just a simple pressing action. This not only improves the safety redundancy of the device through the locking process, but also does not increase the complexity of the device operation. It can still achieve rapid closing and opening, further improving the ease of operation of the device.

[0035] Working principle and usage process:

[0036] Before use, the device is installed using external bolts and fixing ear plate 2. At the same time, when the rotary gate 4 is at the highest and lowest points, the device is in the closed or open state.

[0037] When it is necessary to close or open the circuit, the rotary gate 4 can be rotated to the highest or lowest position. At this time, the L-shaped plate 7 on one side of the rotary gate 4 rotates synchronously and drives the plug-in post 12 to move. The plug-in post 12 can contact the guide slope on the front of the circuit breaker body 1. At this time, the guide slope can apply force to the plug-in post 12, forcing the limit spring 11 to be stretched. At this time, the limit plate 9 and the limit rod 10 move away from the plug-in post 12. At this time, the plug-in post 12 moves towards the fixed tube 8. When the plug-in post 12 moves to the corresponding position of the limit hole 5, the limit spring 11 automatically resets. At this time, the plug-in post 12 and the limit hole 5 are engaged, the device is in the closed or open state, and the position locking process of the rotary gate 4 is completed.

[0038] When it is necessary to release the locked state of the gate being closed or opened, pressure can be applied to the control plate 601 to move it toward the rotary gate 4. At this time, under the guidance of the guide rod 603 and the guide sleeve 602, the control plate 601 can be driven to move toward the rotary gate 4. At this time, the left and right connecting rods 606 deflect accordingly and apply a pushing force to the two extension plates 607. The two extension plates 607 also drive the two plug-in pins 12 to move away from each other until the plug-in pins 12 leave the limit hole 5, thus releasing the lock and allowing the rotary gate 4 to be operated.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
