Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, and particularly relates to a busbar arc protection device. Background Technique

[0002] An arc protection device is an electrical device used to protect loads and electrical equipment in a power system from damage caused by overcurrent and electric arcs. The arc protection device can automatically detect the load current and voltage, and quickly cut off the circuit when abnormal conditions such as overcurrent and overvoltage occur in the circuit, protecting the operator from harm and reducing property losses;

[0003] During the use of the existing arc protection device, a large number of wires need to be connected to the upper end of the protection device. It is not easy to organize and fix the wires for the existing arc protection device, resulting in messy wires.

[0004] For example, the Chinese authorized patent with the publication number of CN 212033757 U (an intelligent busbar arc protection device): By arranging a wire management mechanism at the upper end of the housing, the inserted wire passes through the outer frame through the slot, and then the gear is rotated counterclockwise, so that the gear drives the rack to move to the left end, and the rack drives the sliding shaft to move to the left end. The sliding shaft drives the first clamping jaw and the second clamping jaw to drive through the positioning shaft at the upper end of the fixed seat, so that the first clamping jaw and the second clamping jaw are clamped inward, achieving the advantages of being able to quickly organize and fix the wires and making the wires placed flat. This technical solution solves the above problems;

[0005] However, this technical solution still has some technical problems. The busbar arc protection device fixes the wire by clamping the wire with the first clamping jaw and the second clamping jaw. Since this clamping is a rigid clamping, when the wire is accidentally pulled by the staff, the contact part between the clamping jaw and the wire is prone to breakage under the action of a strong pulling force, affecting the insulation of the wire.

[0006] Therefore, a busbar arc protection device is proposed. Content of the Utility Model

[0007] The purpose of the utility model is to provide a busbar arc protection device to solve the problem that when the wire of the busbar arc protection device is accidentally pulled by the staff, the contact part between the clamping jaw and the wire is prone to breakage under the action of a strong pulling force, affecting the insulation of the wire as mentioned in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A busbar arc protection device, including a busbar arc protection device main body, characterized in that:

There are two rigid cylinders, and a flexible hydraulic pipe is arranged between the two rigid cylinders. Connecting wires are wound around the outside of the flexible hydraulic pipe;

[0010] A transmission hydraulic tank is arranged at the lower end of the partition plate. The lower end of the rigid cylinder extends into the inside of the transmission hydraulic tank.

The silicone protective sleeves are fixedly connected to the main body of the busbar arc protection device. The flexible hydraulic pipe is fixedly connected to both rigid cylinders. The transmission hydraulic tank is welded to the partition plate. A telescopic cylinder is arranged on one side of the rigid cylinder. The telescopic cylinder is fixedly connected to the rigid cylinder. The rotating roller is rotatably connected to the main body of the busbar arc protection device.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. By installing a flexible hydraulic pipe, the connecting wire wound around it can squeeze the flexible hydraulic pipe when being pulled by an external force, deforming the flexible hydraulic pipe. As a result, the connecting wire has a certain margin to stretch, avoiding damage to the connecting wire caused by excessive force and preventing the decline of the insulation performance of the connecting wire. At the same time, hydraulic oil is provided inside the flexible hydraulic pipe. When the flexible hydraulic pipe deforms, the hydraulic oil enters the transmission hydraulic tank under force. The hydraulic oil converts the strong pulling force of the connecting wire into the internal energy of the pressure of the hydraulic oil, thereby absorbing the impact force and preventing the connecting wire from being subjected to too strong a force, making the device more practical.

[0019] 2. By installing a telescopic member, it can push the friction plate and the friction pad to move under the action of hydraulic oil, thereby rotating the rotating roller. Then, the rotating roller drives the knocking ball to rotate through the turntable, causing the knocking ball to knock on the hollow ball, making the hollow ball emit a sound to remind the staff not to pull the connecting wire anymore, playing a warning role and enhancing the safety of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a busbar arc protection device, including a busbar arc protection device main body 1, characterized in that:

[0028] A partition plate 2 is arranged at the lower end inside the busbar arc protection device main body 1. The busbar arc protection device main body 1 is welded to the partition plate 2. Rigid cylinders 5 are fixedly installed inside the partition plate 2 and at the upper end inside the busbar arc protection device main body 1. There are two rigid cylinders 5. A flexible hydraulic pipe 6 is arranged between the two rigid cylinders 5. Installing the flexible hydraulic pipe 6 enables the connecting wire 9 wound around its outside to squeeze the flexible hydraulic pipe 6 when being pulled by an external force, causing the flexible hydraulic pipe 6 to deform. Furthermore, the connecting wire 9 has a certain margin to stretch, avoiding the connecting wire 9 from being damaged due to excessive force and preventing the insulation performance of the connecting wire 9 from decreasing. At the same time, hydraulic oil is arranged inside the flexible hydraulic pipe 6. When the flexible hydraulic pipe 6 deforms, the hydraulic oil enters the transmission hydraulic tank 4 under force. Among them, the hydraulic oil converts the strong pulling force of the connecting wire 9 into the internal energy of the pressure of the hydraulic oil, thereby absorbing the impact force, preventing the connecting wire 9 from being subjected to too strong a force, and making the device more practical. The connecting wire 9 is wound around the outside of the flexible hydraulic pipe 6;

[0029] A transmission hydraulic tank 4 is arranged at the lower end of the partition plate 2. The lower end of the rigid cylinder 5 extends into the inside of the transmission hydraulic tank 4. A telescopic member 19 is horizontally slidably arranged inside the telescopic cylinder 12. Installing the telescopic member 19 can push the friction plate 14 and the friction pad 20 to move under the action of the hydraulic oil. Then, the rotating roller 21 rotates. Then, the rotating roller 21 drives the knocking ball 13 to rotate through the turntable 22, causing the knocking ball 13 to knock the hollow ball 18, making the hollow ball 18 emit a sound to remind the staff not to pull the connecting wire 9 anymore, playing a warning role and enhancing the safety of the device. One end of the telescopic member 19 is fixedly installed with a friction plate 14. The lower end of the friction plate 14 is fixedly installed with a friction pad 20. The lower end of the friction pad 20 is provided with a rotating roller 21. The front end face of the rotating roller 21 is fixedly installed with a turntable 22. The front end face of the turntable 22 is installed with a knocking ball 13. One side of the lower end face of the partition plate 2 is installed with a fixed spring 17. The lower end of the fixed spring 17 is fixedly installed with a hollow ball 18.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, silicone protective sleeves 8 are installed on both sides of the main body 1 of the busbar arc protection device. Installing the silicone protective sleeves 8 can prevent the connecting wire 9 from shaking, play a role in stable buffering support, enhance the practicability of the device. The silicone protective sleeves 8 are fixedly connected to the main body 1 of the busbar arc protection device. The flexible hydraulic pipe 6 is fixedly connected to both rigid cylinders 5. The transmission hydraulic tank 4 is welded to the partition plate 2. A telescopic cylinder 12 is provided on one side of the rigid cylinder 5. The telescopic cylinder 12 is fixedly connected to the rigid cylinder 5. The rotating roller 21 is rotatably connected to the main body 1 of the busbar arc protection device. On the other side of the rear end face inside the main body 1 of the busbar arc protection device, a mounting plate 11 is fixedly installed. An arc sensor 10 is fixedly installed inside the mounting plate 11. At the lower end of the other side of the rear end face inside the main body 1 of the busbar arc protection device, a central processor 3 is installed. The central processor 3 is fixedly connected to the main body 1 of the busbar arc protection device. At the rear end of the upper end face of the main body 1 of the busbar arc protection device, a fixing plate 7 is installed. The fixing plate 7 is fixedly connected to the main body 1 of the busbar arc protection device. A return spring 23 is arranged outside the telescopic member 19. Installing the return spring 23 can make the telescopic member 19 retract into the telescopic cylinder 12, and make the hydraulic oil be pressed back into the flexible hydraulic pipe 6 to ensure the functional position of the device. One end of the return spring 23 close to the transmission hydraulic tank 4 is fixedly connected to the telescopic member 19. A mounting panel 15 is installed on the front end face of the main body 1 of the busbar arc protection device. The mounting panel 15 is connected to the main body 1 of the busbar arc protection device by screws. A display screen 16 is arranged at the upper end of the front end face of the mounting panel 15. A circuit breaker is arranged on one side inside the main body 1 of the busbar arc protection device.

[0031] Working principle: When in use, the staff installs this device at the required place and uses screws to install it at the front end of the fixed plate 7 to fix the device. Then, the staff winds the connecting wire 9 around the outside of the flexible hydraulic pipe 6 and electrically connects the connecting wire 9 to the device to complete the installation. When the device is in use, the arc light sensor 10 will detect the intensity of the arc light. When the arc light intensity is higher than the set threshold, the central processor 3 controls the circuit breaker to cut off the power supply. When the staff accidentally pulls the connecting wire 9 during work, the connecting wire 9 deforms under force, avoiding damage to the connecting wire 9 due to force. The connecting wire 9 squeezes the flexible hydraulic pipe 6, causing the flexible hydraulic pipe 6 to deform and providing space for the deformation of the connecting wire 9. Then, the hydraulic oil inside the flexible hydraulic pipe 6 is pressed into the transmission hydraulic tank 4, causing the telescopic member 19 to push the friction plate 14 and the friction pad 20 to move under the action of the hydraulic oil, thereby causing the rotating roller 21 to rotate. Then, the rotating roller 21 drives the knocking ball 13 to rotate through the turntable 22, causing the knocking ball 13 to knock on the hollow ball 18, making the hollow ball 18 emit a sound to remind the staff not to pull the connecting wire 9 anymore, playing a warning role and enhancing the safety of the device. Installing the flexible hydraulic pipe 6 in this device can enable the connecting wire 9 wound around its outside to squeeze the flexible hydraulic pipe 6 when being pulled by an external force, causing the flexible hydraulic pipe 6 to deform, and further enabling the connecting wire 9 to have a certain margin for stretching, avoiding damage to the connecting wire 9 due to excessive force and preventing the occurrence of a situation where the insulation performance of the connecting wire 9 deteriorates. At the same time, the inside of the flexible hydraulic pipe 6 is provided with hydraulic oil. When the flexible hydraulic pipe 6 deforms, the hydraulic oil is forced into the transmission hydraulic tank 4. Among them, the hydraulic oil converts the strong pulling force of the connecting wire 9 into the pressure internal energy of the hydraulic oil, thereby absorbing the impact force and preventing the connecting wire 9 from being subjected to too strong a force, making the device more practical. Installing the silicone protective sleeve 8 can prevent the connecting wire 9 from shaking, playing a role of stable buffering support and enhancing the practicality of the device. Installing the return spring 23 can enable the telescopic member 19 to retract into the telescopic cylinder 12, pressing the hydraulic oil back into the flexible hydraulic pipe 6 to ensure the functional position of the device.
