Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a multifunctional circuit breaker controlled by a cloud platform. Background Technology

[0002] With the deep integration of smart grid construction into rural areas, cloud-platform controlled miniature circuit breakers (MPCs) have become one of the core devices for the intelligent upgrading of rural power distribution networks due to their advantages such as remote control and real-time status monitoring. These circuit breakers can remotely issue opening and closing commands, collect operational data, and provide fault warnings through a cloud platform, significantly improving the operation and maintenance efficiency and power supply reliability of rural power grids, and meeting the upgraded needs of rural users for safer and more convenient electricity use. Their application scenarios cover multiple areas such as rural household power supply, small agricultural machinery power supply, and temporary outdoor power supply, and are particularly well-suited to the characteristics of decentralized electricity use in rural areas, providing key technical support for the intelligent transformation of rural power grids.

[0003] The current mainstream cloud platform-controlled miniature circuit breakers (MCBs) consist of the circuit breaker body, a mechanical control handle, and a built-in cloud communication and control module. The control handle is used for local emergency opening and closing operations. The cloud communication and control module is the core technology component, comprising three main parts: a wireless communication unit, a main control chip, and a power supply module. The wireless communication unit establishes a stable connection with the cloud platform via Wi-Fi, LoRa, or 4G / 5G networks, enabling bidirectional data transmission. The main control chip parses the opening and closing commands issued by the cloud platform, drives the actuator to complete the action, and simultaneously collects and uploads data such as current, voltage, and equipment operating status to the cloud. The power supply module adopts a dual power supply mode, using either circuit power or a built-in backup battery, ensuring stable power for the communication unit and main control chip under various operating conditions, guaranteeing continuous and reliable equipment operation, and providing dual protection for local operation and cloud-based management.

[0004] However, in non-standard outdoor application scenarios in rural areas, the actual application of this type of circuit breaker presents significant safety hazards. Some rural users, in order to reduce installation costs and simplify construction processes, fail to configure protective devices such as distribution boxes as required by regulations, directly exposing and fixing the circuit breaker under the eaves of their houses. Although the eaves can block some sunlight and vertical rainfall, the rural outdoor environment is complex. During rainy days accompanied by strong winds, rainwater can easily seep into the circuit breaker's wiring terminals, cable connections, and control handle gaps through splashing and spraying. Furthermore, the large temperature difference between day and night and high humidity in rural outdoor areas make the equipment highly susceptible to water ingress and moisture, leading to short circuits, leakage, and other faults, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a multi-functional circuit breaker controlled by a cloud platform, which solves the problem in the above-mentioned related technologies that circuit breakers are prone to water ingress and moisture at the wiring ports in non-standard outdoor scenarios in rural areas, causing safety hazards.

[0006] The multi-functional circuit breaker controlled by a cloud platform provided in this application adopts the following technical solution: A multi-functional circuit breaker controlled by a cloud platform includes a main body, a cloud control module located within the main body, and a fixing part fixed to the front side of the main body. A control handle is rotatably mounted on the front side of the fixing part. Several wiring ports are provided on the upper and lower sides of the main body. Connecting plates are rotatably mounted vertically on the rear edges of the left and right sides of the main body. Protective shells are fixed on the sides of the connecting plates away from the main body. The two protective shells can rotate towards each other to abut against each other and protect the front side of the main body. Positioning plates that can rotate to a horizontal position towards the front are rotatably mounted on the rear edges of the upper and lower sides of the main body. When the positioning plates are in the horizontal position, a first arc-shaped opening is provided on the front side. When the protective shells are in the protective position, a second arc-shaped opening is provided on the back side. Elastic pads are fixed on the inner walls of the first and second arc-shaped openings. The positioning plates are provided with locking elements to lock the protective shells in the protective position. When the positioning plates are in the horizontal position and the protective shells are in the protective position, the first and second arc-shaped openings together form a limiting cavity coaxial with the wiring ports. At this time, the elastic pads can press against the outer circumference of the external cables.

[0007] By adopting the above technical solution, connecting plates and protective shells are rotatably installed on the rear edges of the left and right sides of the main body. When the two protective shells rotate towards each other and abut, they protect the front of the main body, effectively preventing rainwater from splashing or spraying onto critical areas such as the wiring ports. Simultaneously, positioning plates rotatably installed on the rear edges of the upper and lower sides of the main body rotate to a horizontal position, engaging with the arc-shaped openings on the protective shells to form a limiting cavity coaxial with the wiring ports. The elastic pads on the inner walls of the limiting cavity can press firmly against the outer circumference of the external cables, further preventing rainwater from entering through the gaps between the wiring ports and the cables. Furthermore, locking components on the positioning plates can lock the protective shells in the protected state, ensuring the stability of the protection.

[0008] Optionally, the locking element includes two locking protrusions fixed on the front side of the positioning plate when it is in a horizontal state, and a locking notch is provided on the back side of the protective shell when it is in a protective state for the locking protrusions to rotate into; an elastic snap-fit ​​element is provided on the outer side of the locking protrusions, and a positioning groove is provided on the inner wall of the locking notch for the elastic snap-fit ​​element to snap into.

[0009] By adopting the above technical solution, the locking protrusion rotates into the locking notch, and the elastic snap-fit ​​component engages with the positioning groove, thus securely locking the protective shell in its protective state onto the positioning plate. This locking method is simple and reliable in structure, effectively preventing accidental rotation of the protective shell, ensuring continuous protection of the circuit breaker, and improving operational safety.

[0010] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. The locking protrusion has a placement groove for the compression spring and the arc-shaped protrusion to be inserted. The compression spring presses one side of the arc-shaped protrusion, causing a part of the arc-shaped protrusion to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc surface is a minor arc.

[0011] By adopting the above technical solution, the compression spring squeezes the arc-shaped protrusion so that it partially protrudes from the placement groove. When locking, the arc surface of the arc-shaped protrusion facilitates its smooth sliding into the positioning groove of the locking notch. Moreover, the arc surface is a minor arc, which can enhance the locking stability, prevent easy disengagement, ensure reliable locking of the protective shell, and improve the overall structural stability.

[0012] Optionally, when the two protective shells are in the protective state, a clearance notch is provided on the lower side of the shells that are close to each other. A control rod is provided vertically on the front side of the main body. A control protrusion is fixed on the outer periphery of the upper end of the control rod. A control notch is provided on the control protrusion. When the two protective shells are in the protective state, the lower end of the control rod passes through the clearance notch. The control handle is then inserted into the control notch. When the control rod moves up and down, the control handle can be rotated.

[0013] By adopting the above technical solution, when the protective shell is in the protected state, the lower end of the control rod passes through the clearance notch, and the control handle is engaged with the control notch. This design allows the control handle to be operated simply by moving the control rod up and down in the protected state, thus ensuring effective protection of the front side of the main body by the protective shell, preventing rainwater and other intrusions, while also enabling convenient local emergency opening and closing operations without removing the protective shell. This balances protection and ease of operation, improving the practicality and safety of the circuit breaker in complex rural outdoor environments.

[0014] Optionally, an upper baffle and a lower baffle are fixedly provided on the outer periphery of the lower end of the control lever; the upper baffle is located inside the protective shell when the control handle is inserted into the control notch, and the lower baffle is located below the protective shell.

[0015] By adopting the above technical solution, when the control handle is engaged in the control notch, the upper baffle is inside the protective shell, and the lower baffle is below the protective shell, forming a limiting structure. The upper baffle can prevent the control lever from moving excessively upward, avoiding the control handle from dislodging from the control notch and ensuring operational stability; the lower baffle can limit the downward movement range of the control lever, preventing it from detaching from the protective shell.

[0016] Optionally, the control rod can be installed vertically in reverse when the circuit breaker needs to be temporarily moved, with the lower baffle located inside the protective housing and the upper baffle located below the protective housing.

[0017] By adopting the above technical solution, when the circuit breaker needs to be temporarily moved, the control rod is installed vertically in the opposite direction, the lower baffle enters the protective shell, and the upper baffle is located below the protective shell. This design cleverly changes the position of the baffle, and the movers can directly hold the control rod towards the end of the control protrusion for moving.

[0018] Optionally, the upper and lower sides of the main body are provided with two elastic telescopic rods with active extension performance. One end of the elastic telescopic rod is rotatably connected to the top surface of the positioning plate when it is in a horizontal state. A fixing block is fixed on the top surface of the protective shell. The fixing block has a fixing slot on the back side of the protective shell when it is in a protective state for the elastic telescopic rod to be inserted.

[0019] By adopting the above technical solution, elastic telescopic rods with active extension capabilities are installed on the upper and lower sides of the main body. One end of each rod is rotatably connected to a positioning plate, and a fixing block and a fixing slot are provided on the top surface of the protective shell. When the protective shell is in the protective state, the elastic telescopic rods can actively extend and engage with the fixing slots to further secure the protective shell, enhance its stability, and prevent the protective shell from shaking or shifting due to external forces such as strong winds, thereby improving the protection effect on the circuit breaker. At the same time, this connection method is relatively convenient for installation and disassembly, and the fixing can be quickly released when maintenance or other operations are required, balancing the reliability of protection with the convenience of use, and adapting to the complex outdoor environment in rural areas.

[0020] Optionally, when the positioning plate is in a horizontal state, the rotating surface of the elastic telescopic rod is parallel to the horizontal plane, a positioning slot is provided on the top surface of the elastic telescopic rod, and two positioning protrusions are fixed on the outer periphery of the control rod; when the circuit breaker needs maintenance, the two connecting plates can rotate in opposite directions to a state flush with the back side of the main body, and the elastic telescopic rod can rotate synchronously and be inserted into the fixed slot at this time. The two positioning protrusions on the control rod can be inserted into the positioning slots respectively to lock the rotation state of the two elastic telescopic rods.

[0021] By adopting the above technical solution, during maintenance, the connecting plate rotates to be flush with the back side of the main body, and the elastic telescopic rod rotates synchronously and engages with the fixing slot. The positioning protrusion of the control rod inserts into the positioning slot to lock its rotation state. This design can properly fix the elastic telescopic rod during maintenance, preventing it from shaking and interfering with maintenance operations, ensuring the safety of maintenance personnel and the smooth progress of maintenance work.

[0022] Optionally, a flexible receiving curtain is provided below the main body, and several hooks are fixed on the opposite side of the flexible receiving curtain, and several retaining rings are fixed on the bottom surface of the protective shell; the hooks can engage with the retaining rings when the connecting plate is rotated to a state flush with the back side of the main body, and the flexible receiving curtain can be used for temporary placement of maintenance tools and replacement parts at this time.

[0023] By adopting the above technical solution, a flexible receiving curtain is installed below the main body, with its side hooks engaging with the retaining rings on the bottom of the protective shell. When the connecting plate is rotated to be flush with the back side of the main body for maintenance, the hooks engage with the retaining rings, and the flexible receiving curtain can be unfolded for temporary placement of maintenance tools and replacement parts. This provides convenient placement space for maintenance, preventing tools and parts from being lost or damaged due to random placement. Furthermore, the flexible receiving curtain is easy to store without taking up extra space, improving the efficiency and convenience of circuit breaker maintenance.

[0024] Optionally, the outer periphery of the control rod is provided with a storage cavity for inserting a flexible receiving curtain, and a cover plate that can be detachably installed to seal the storage cavity.

[0025] By adopting the above technical solution, a storage cavity and a detachable cover are provided on the outer periphery of the control rod. When not under maintenance, the flexible receiving curtain can be placed into the storage cavity and then sealed with the cover, making the overall structure more compact and the appearance neater. This avoids the flexible receiving curtain being exposed and damaged or interfering with other operations, improving the practicality and aesthetics of the product and adapting it to various usage scenarios.

[0026] In summary, this application includes the following beneficial technical effects: Connecting plates and protective shells are rotatably installed along the rear edges of the left and right sides of the main body. When the two protective shells rotate towards each other and come into contact, they can protect the front of the main body, effectively preventing rainwater from splashing or spraying onto critical parts such as the wiring port. At the same time, positioning plates rotatably installed along the rear edges of the upper and lower sides of the main body rotate to a horizontal position, which cooperates with the arc-shaped opening on the protective shell to form a limiting cavity coaxial with the wiring port. The elastic pads on the inner wall of the limiting cavity can press tightly against the outer circumference of the external cable, further preventing rainwater from entering through the gap between the wiring port and the cable.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A multi-functional circuit breaker controlled by a cloud platform includes a main body 1, a cloud control module (not shown in the figure) located inside the main body 1, a fixing part 11 fixed to the front side of the main body 1, a control handle 12 rotatably installed on the front side of the fixing part 11, two wiring ports 13 opened on the upper and lower sides of the main body 1, and protective components 2 provided on the left and right sides of the main body 1. The protective component 2 includes two connecting plates 21 that are vertically rotatably mounted on the rear edge of the left and right sides of the main body 1. A protective shell 22 is fixed on the side of the connecting plate 21 away from the main body 1. The protective shell 22 is made of transparent plastic. The two protective shells 22 can rotate towards each other to abut against each other and protect the front side of the main body 1. At this time, the rotation state of the control handle 12 can be observed through the protective shell 22. The rear edges of the upper and lower sides of the main body 1 are rotatably mounted with positioning plates 3 that can rotate to a horizontal position in the direction of the front; when the positioning plate 3 is in a horizontal position, a first arc-shaped opening 31 is opened on the front side, and when the protective shell 22 is in a protective position, a second arc-shaped opening 221 is opened on the back side. The inner walls of the first arc-shaped opening 31 and the second arc-shaped opening 221 are both fixed with elastic pads 32 made of rubber, and the positioning plate 3 is provided with a locking piece 4. When the positioning plate 3 is in a horizontal state and the protective shell 22 is in a protective state, the locking member 4 limits and locks the protective shell 22 in this state. The first arc-shaped opening 31 and the second arc-shaped opening 221 together form a limiting cavity coaxial with the wiring port 13. At this time, the elastic pad 32 can press against the outer peripheral surface of the external cable.

[0031] Reference Figure 5 and Figure 6 The locking component 4 includes two locking protrusions 41 fixed on the front side of the positioning plate 3 when it is in a horizontal state. An elastic snap-fit ​​component 42 is provided on the outer side of the locking protrusion 41. The elastic snap-fit ​​component 42 includes a compression spring 421 and an arc-shaped protrusion 422. The locking protrusion 41 is provided with a placement groove 411 for the compression spring 421 and the arc-shaped protrusion 422 to be placed. The compression spring 421 presses one side of the arc-shaped protrusion 422 so that a part of the arc-shaped protrusion 422 protrudes from the opening of the placement groove 411. The outer side of the protruding part of the arc-shaped protrusion 422 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. The protective shell 22 has a locking notch 222 on its back side when it is in the protective state, into which the locking protrusion 41 can rotate. The inner wall of the locking notch 222 has a positioning groove 2221. When the locking member 4 locks the protective shell 22 in the protective state, the locking protrusion 41 rotates into the locking notch 222. At this time, the elastic snap-fit ​​member 42 snaps into the positioning groove 2221, improving the installation stability of the locking protrusion 41 in the locking notch 222.

[0032] Reference Figure 7 and Figure 8 When the two protective shells 22 are in the protective state, a clearance notch 223 is provided on the side of the lower part that is close to each other. A control component 5 is provided on the front side of the main body 1. The control component 5 includes a control rod 51 installed vertically. A control protrusion 52 is fixed on the outer periphery of the upper end of the control rod 51. A control notch 521 is provided on the control protrusion 52. An upper baffle 53 and a lower baffle 54 are fixed on the outer periphery of the lower end of the control rod 51. When the two protective shells 22 are in the protective state, the lower end of the control rod 51 passes through the clearance notch 223, and the control handle 12 is inserted into the control notch 521. At this time, the upper baffle 53 is located inside the protective shell 22, and the lower baffle 54 is located below the protective shell 22. The upper baffle 53 and the lower baffle 54 limit the up and down sliding stroke of the control rod 51, and the control handle 12 can be rotated when the control rod 51 moves up and down. When the circuit breaker needs to be temporarily moved, the staff can release the locking piece 4 from the protective housing 22, install the control rod 51 vertically in the reverse direction, and then use the locking piece 4 to lock the protective housing 22 to the protective state. At this time, the lower baffle 54 is located inside the protective housing 22, and the upper baffle 53 is located below the protective housing 22. The moving personnel can directly hold the end of the control rod 51 facing the control protrusion 52.

[0033] Reference Figure 9 A fixing block 23 is fixed on the top surface of the protective shell 22; the upper and lower sides of the main body 1 are provided with two elastic telescopic rods 6 with active extension performance. One end of the elastic telescopic rod 6 is rotatably connected to the top surface of the positioning plate 3 when it is in a horizontal state. The rotation surface of the elastic telescopic rod 6 when it is in a horizontal state with the positioning plate 3 is parallel to the horizontal plane. The elastic telescopic rod 6 is a conventional elastic telescopic structure, which will not be described in detail here. When the protective shell 22 is in the protective state, a fixing slot 231 is provided on the back side of the fixing block 23 for the elastic telescopic rod 6 to be inserted. The state of the protective shell 22 is further locked by the insertion of the elastic telescopic rod 6 and the fixing block 23. When unlocking is required, the staff can apply force to remove the elastic telescopic rod 6 from the fixing slot 231.

[0034] Reference Figure 10 and Figure 11 The top surface of the elastic telescopic rod 6 is provided with a positioning slot 61, and two positioning protrusions 511 are fixed on the outer periphery of the control rod 51 away from the fixed protrusion. When it is necessary to inspect the control handle 12 on the circuit breaker, the two connecting plates 21 can rotate back to back to the state of being flush with the back side of the main body 1. At this time, the elastic telescopic rod 6 can rotate synchronously and be inserted into the fixed slot 231. At this time, the two positioning protrusions 511 on the control rod 51 can be inserted into the positioning slot 61 respectively to lock the rotation state of the two elastic telescopic rods 6.

[0035] Reference Figure 12 and Figure 13 A flexible receiving curtain 7 is provided below the main body 1. Two hooks 71 are fixed on the opposite sides of the flexible receiving curtain 7. Two retaining rings 224 are fixed on the bottom surface of the protective shell 22. When the connecting plate 21 is rotated to be flush with the back side of the main body 1, the hooks 71 can be engaged with the corresponding retaining rings 224. At this time, the flexible receiving curtain 7 can be used to temporarily place maintenance tools and replacement parts.

[0036] Reference Figure 14 The outer periphery of the control rod 51 is provided with a storage cavity 512 for the flexible receiving curtain 7 to be inserted, and a cover plate 513 is rotatably installed to seal the storage cavity 512. The side of the cover plate 513 away from the rotating shaft is fixed to the opening of the storage cavity 512 by screws. This is a conventional locking structure, which will not be described in detail here.

[0037] The implementation principle of this application embodiment is as follows: Normal operating state: The two protective shells 22 rotate towards each other until they abut each other, thus entering a protective state. The rotation of the control handle 12 can be observed through the transparent protective shells 22. The positioning plate 3 rotates to a horizontal position, and the locking member 4 limits and locks the protective shell 22. The first arc-shaped opening 31 and the second arc-shaped opening 221 together form a limiting cavity, and the elastic pad 32 presses against the external cable. The lower end of the control rod 51 passes through the clearance notch 223 of the protective shell 22, and the control handle 12 is engaged in the control notch 521. The upper and lower baffles 54 limit the up and down sliding stroke of the control rod 51. The up and down movement of the control rod 51 can drive the control handle 12 to rotate.

[0038] Temporary handling state: Release the locking piece 4 from the protective shell 22, install the control lever 51 vertically in the reverse direction, and then relock the protective shell 22. At this time, the lower baffle 54 is located inside the protective shell 22, and the upper baffle 53 is located below the protective shell 22. The handling personnel can directly hold the end of the control lever 51 facing the control protrusion 52 for handling.

[0039] Maintenance status: The two connecting plates 21 rotate back to back until they are flush with the back side of the main body 1. The elastic telescopic rod 6 rotates synchronously and engages with the fixing slot 231. The positioning protrusion 511 on the control rod 51 inserts into the positioning slot 61, locking the rotation state of the elastic telescopic rod 6. At the same time, the hook 71 engages with the retaining ring 224, and the flexible receiving curtain 7 can temporarily hold maintenance tools and replacement parts. After maintenance is completed, the tools and parts are placed back into the storage cavity 512, sealed with the cover plate 513, and fixed with screws.
