Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an electrical engineering power distribution circuit breaker. Background Technology

[0002] Distribution circuit breakers are critical electrical devices widely used in power distribution networks. They primarily function to protect circuits and isolate faults, ensuring the stable operation of the power system. Through internal thermomagnetic or electronic tripping devices, distribution circuit breakers can quickly detect abnormalities such as overloads and short circuits in the circuit and automatically disconnect the circuit upon detection of a fault, thus preventing the fault from escalating and protecting equipment and personnel safety. They also have manual operation capabilities, allowing operators to close and open the circuit as needed. In terms of structural design, distribution circuit breakers typically employ a modular design for easy installation, maintenance, and upgrades. Their casings are usually made of insulating materials to enhance safety and reliability. Furthermore, distribution circuit breakers are equipped with various auxiliary functions, such as fault indication, current measurement, and voltage monitoring, to meet the needs of different applications. With the development of power systems, the technology of distribution circuit breakers is constantly advancing. Modern distribution circuit breakers not only have higher performance and more reliable protection functions but also incorporate advanced technologies such as intelligence and networking, enabling remote monitoring, fault diagnosis, and automatic reclosing, further improving the operating efficiency and safety of the power system.

[0003] However, existing electrical circuit breakers are inconvenient to install and disassemble. They require bolts for installation and wrenches or screwdrivers for removal. Since wrenches and screwdrivers are not portable, this inconvenience increases maintenance costs by requiring more time and effort from maintenance personnel. Furthermore, their compact internal structure hinders heat dissipation, which accelerates the aging of electronic components. Some components deteriorate at high temperatures, such as reduced accuracy of circuit breaker operation and potential malfunctions or poor contact of contactors. Therefore, further improvements are needed. Summary of the Invention

[0024] Reference Figures 1 to 7 In this embodiment of the invention, an electrical engineering power distribution circuit breaker specifically includes the following embodiments:

[0025] Example 1

[0026] The circuit breaker mechanism 1 includes a mounting block mechanism 2 for easy installation on one side, a mounting mechanism 3 for quick installation and removal of the circuit breaker mechanism 1 on one side, and a heat dissipation mechanism 4 for cooling the circuit breaker mechanism 1 on one side. The mounting mechanism 3 includes a threaded rod 31 screwed to one side of the mounting block mechanism 2, a rotating wheel 32 fixedly connected above the threaded rod 31, a handle 33 fixedly connected to one end of the rotating wheel 32, a limit plate 34 rotatably connected below the threaded rod 31, a first connecting frame 35 fixedly connected to one end of the limit plate 34, and a first connecting frame 35 fixedly connected to one side of the first connecting frame 35. The installation block mechanism 2 includes a first protrusion 36 for limiting movement during installation; a first rotating block 37 is rotatably connected to one side of a first connecting frame 35; a rotating disk 38 is rotatably connected to one side of the first rotating block 37; a second rotating block 39 is rotatably connected to one side of the rotating disk 38; a second connecting frame 310 is rotatably connected to one side of the second rotating block 39; a second protrusion 311 is fixedly connected to one side of the second connecting frame 310; and a third rotating block 312 is rotatably connected to one side of the rotating disk 38. The installation block mechanism 2 includes an installation block body 21 disposed on one side of the installation mechanism 3; a stop 22 is fixedly connected to one side of the installation block body 21; and a threaded hole 23 is provided at one upper end of the stop 22. The mounting block body 21 has a filter screen 24 for filtering dust embedded at one side end, and a limiting block 25 is fixedly connected to one side end of the mounting block body 21. A limiting groove 26 is opened at one side end of the limiting block 25. The power distribution circuit breaker mechanism 1 includes a power distribution circuit breaker body 11 disposed at one side end of the mounting block mechanism 2. A heat-conducting plate 12 is embedded at one side end of the power distribution circuit breaker body 11, and a heat dissipation fin 13 is provided at one side end of the heat-conducting plate 12. A mounting groove 14 adapted to the mounting mechanism 3 is opened at one side end of the power distribution circuit breaker body 11. The mounting groove 14 has a groove that can just accommodate the first protrusion 36 and the second protrusion 311, and can also accommodate the first connecting frame 35 and the second connecting frame 310. The sliding block 22 and the limiting block 25 are arranged in three sets, which are located around the side of the mounting block body 21. The blocking block 22 and the limiting block 25 are all at the same height, which allows them to fit against the side of the power distribution circuit breaker mechanism 1. The number of three sets can prevent it from tilting or shaking. The threaded hole 23 is adapted to the threaded rod 31. The limiting groove 26 is adapted to the first connecting frame 35 and the second connecting frame 310. The limiting groove 26 can limit the first connecting frame 35 and the second connecting frame 310 to prevent them from deviating. The number of the second connecting frame 310 and the second protrusion 311 is arranged in two sets, which are located on the side of the second rotating block 39 and the third rotating block 312.

[0027] The above solution involves fixing the mounting block body 21 to the desired installation location, aligning the mounting groove 14 on the side of the circuit breaker body 11 with the first connecting frame 35 and the second connecting frame 310, and then rotating the handle 33 to drive the rotating wheel 32 and the threaded rod 31 to rotate. Under the action of the threaded hole 23, the first connecting frame 35 can be moved in the limiting groove 26. When the first connecting frame 35 moves, it drives the rotating disk 38 connected to the side to rotate. When the rotating disk 38 rotates, it drives the second rotating block 39 and the third rotating block 312 on the side to rotate synchronously, thereby driving the other two sets of second connecting frames 310 to move synchronously. This allows the first protrusion 36 and the second protrusion 311 on the side to be engaged in the mounting groove 14, thereby limiting the circuit breaker mechanism 1 and achieving installation.

[0028] Example 2

[0029] The circuit breaker mechanism 1 includes a mounting block mechanism 2 for easy installation on one side, a mounting mechanism 3 for quick installation and removal of the circuit breaker mechanism 1 on one side, and a heat dissipation mechanism 4 for cooling the circuit breaker mechanism 1 on one side. The mounting block mechanism 2 includes a mounting block body 21 on one side of the mounting mechanism 3, a stop block 22 fixedly connected to one side of the mounting block body 21, a threaded hole 23 at one upper end of the stop block 22, a filter screen 24 for filtering dust embedded on one side of the mounting block body 21, and a limit block 25 fixedly connected to one side of the mounting block body 21, with a limit groove 26 at one side. The heat dissipation mechanism 4 includes a support base 41 fixedly connected to one side of the mounting block mechanism 2, and a connection point for connecting with other components fixedly connected to one side of the support base 41. The support frame 42 is connected to the main shaft 44, and the main shaft 44 is fixedly connected to the output shaft of the main shaft 44. The drive motor 43 and the fan blade 45 are fixedly connected to the main shaft 44. The drive motor 43 and the fan blade 45 are existing technologies. The fixing block 46 is fixedly connected to the main shaft 44. The brush 47 for cleaning dust is fixedly connected to the side of the fixing block 46. The brush 47 is existing technology and can clean the dust on the surface of the heat dissipation fins 13 by rotating. The power distribution circuit breaker mechanism 1 includes a power distribution circuit breaker body 11 set at one side of the mounting block mechanism 2. A heat conduction plate 12 is embedded at one side of the power distribution circuit breaker body 11. The heat conduction plate 12 is made of copper and has good thermal conductivity. A heat dissipation fin 13 is set at one side of the heat conduction plate 12. The heat dissipation fin 13 is existing technology. A mounting groove 14 adapted to the mounting mechanism 3 is opened at one side of the power distribution circuit breaker body 11.

[0030] The above solution is adopted: the drive motor 43 drives the main shaft 44 to rotate, thereby driving the side fan blades 45 and the fixing block 46 to rotate. When the fan blades 45 rotate, they can dissipate heat from the heat dissipation fins 13 and the heat conduction plate 12. When the fixing block 46 rotates, the side brush 47 can clean the dust attached to the heat dissipation fins 13. The heat generated by the circuit breaker body 11 during operation is conducted through the heat conduction plate 12 and finally transferred to the heat dissipation fins 13, thereby improving the heat dissipation effect.

[0031] Example 3

[0032] The circuit breaker mechanism 1 includes a mounting block mechanism 2 for easy installation on one side, a mounting mechanism 3 for quick installation and removal of the circuit breaker mechanism 1 on one side, and a heat dissipation mechanism 4 for cooling the circuit breaker mechanism 1 on one side. The mounting mechanism 3 includes a threaded rod 31 screwed to one side of the mounting block mechanism 2, a rotating wheel 32 fixedly connected above the threaded rod 31, a handle 33 fixedly connected to one end of the rotating wheel 32, a limit plate 34 rotatably connected below the threaded rod 31, a first connecting frame 35 fixedly connected to one end of the limit plate 34, and a first connecting frame 35 fixedly connected to one side of the first connecting frame 35. The installation block mechanism 2 includes a first protrusion 36 for limiting movement during installation; a first rotating block 37 is rotatably connected to one side of a first connecting frame 35; a rotating disk 38 is rotatably connected to one side of the first rotating block 37; a second rotating block 39 is rotatably connected to one side of the rotating disk 38; a second connecting frame 310 is rotatably connected to one side of the second rotating block 39; a second protrusion 311 is fixedly connected to one side of the second connecting frame 310; and a third rotating block 312 is rotatably connected to one side of the rotating disk 38. The installation block mechanism 2 includes an installation block body 21 disposed on one side of the installation mechanism 3; a stop 22 is fixedly connected to one side of the installation block body 21; and a threaded hole 23 is provided at one upper end of the stop 22. The mounting block body 21 has a filter screen 24 for filtering dust embedded at one side end, and a limiting block 25 is fixedly connected to one side end of the mounting block body 21. A limiting groove 26 is opened at one side end of the limiting block 25. The power distribution circuit breaker mechanism 1 includes a power distribution circuit breaker body 11 disposed at one side end of the mounting block mechanism 2. A heat-conducting plate 12 is embedded at one side end of the power distribution circuit breaker body 11, and a heat dissipation fin 13 is provided at one side end of the heat-conducting plate 12. A mounting groove 14 adapted to the mounting mechanism 3 is opened at one side end of the power distribution circuit breaker body 11. The mounting groove 14 has a groove that can just accommodate the first protrusion 36 and the second protrusion 311, and can also accommodate the first connecting frame 35 and the second connecting frame 310. The sliding block 22 and the limiting block 25 are arranged in three sets, which are located around the side of the mounting block body 21. The blocking block 22 and the limiting block 25 are all at the same height, which allows them to fit against the side of the power distribution circuit breaker mechanism 1. The number of three sets can prevent it from tilting or shaking. The threaded hole 23 is adapted to the threaded rod 31. The limiting groove 26 is adapted to the first connecting frame 35 and the second connecting frame 310. The limiting groove 26 can limit the first connecting frame 35 and the second connecting frame 310 to prevent them from deviating. The number of the second connecting frame 310 and the second protrusion 311 is arranged in two sets, which are located on the side of the second rotating block 39 and the third rotating block 312.

[0033] Using the above scheme: by rotating the handle 33 in the opposite direction, the rotating wheel 32 and the threaded rod 31 are driven to rotate. Under the action of the threaded hole 23, the first connecting frame 35 can be moved in the limiting groove 26. When the first connecting frame 35 moves, it drives the rotating disk 38 connected to the side to rotate. When the rotating disk 38 rotates, it drives the second rotating block 39 and the third rotating block 312 on the side to rotate synchronously, thereby driving the other two sets of second connecting frames 310 to move synchronously. This causes the first protrusion 36 and the second protrusion 311 on the side to disengage from the mounting groove 14, thereby losing the limitation on the distribution circuit breaker mechanism 1. At this time, the distribution circuit breaker mechanism 1 can be removed, which is convenient for disassembly of the distribution circuit breaker mechanism 1.

[0034] The working principle of this invention is as follows: First, the mounting block body 21 is fixed to the location where it needs to be installed. The mounting slot 14 on the side of the circuit breaker body 11 is aligned with the first connecting frame 35 and the second connecting frame 310 and inserted. Then, by rotating the handle 33, the rotating wheel 32 and the threaded rod 31 are driven to rotate. Under the action of the threaded hole 23, the first connecting frame 35 can be moved in the limiting slot 26. When the first connecting frame 35 moves, it drives the rotating disk 38 connected to the side to rotate. When the rotating disk 38 rotates, it drives the second rotating block 39 and the third rotating block 312 on the side to rotate synchronously, thereby driving the other two sets of second connecting frames 310 to rotate synchronously. The circuit breaker mechanism 1 is moved step by step, so that the first protrusion 36 and the second protrusion 311 on the side can be engaged into the mounting groove 14, thereby limiting the position of the circuit breaker mechanism 1 and realizing the installation. Then, the main shaft 44 is driven to rotate by the drive motor 43, which in turn drives the fan blade 45 and the fixing block 46 on the side to rotate. When the fan blade 45 rotates, it can dissipate heat from the heat dissipation fins 13 and the heat conduction plate 12. When the fixing block 46 rotates, the brush 47 on the side can clean the dust attached to the heat dissipation fins 13. The heat generated by the circuit breaker body 11 during operation is conducted through the heat conduction plate 12 and finally transferred to the heat dissipation fins 13, thereby improving the heat dissipation effect.

[0035] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
