Description

Technical Field

[0001] This invention belongs to the field of smart grid power distribution equipment technology, and particularly relates to an energy-saving smart distribution box for smart grids. Background Technology

[0002] In the comprehensive construction of smart grids, distribution boxes, as key terminal equipment in the power distribution network, directly impact system energy consumption and operational stability through their cable management methods. Traditional distribution boxes typically employ simple bundling or scattered fixing of cables, lacking hierarchical, categorized, and zoned orderly management. This easily leads to problems such as cable compression, poor contact, and localized overheating, significantly increasing line losses and ineffective energy consumption, which contradicts the high-efficiency and energy-saving development direction of smart grids. Furthermore, messy wiring exacerbates localized temperature rises, accelerates component aging, further increasing the overall energy consumption of the power distribution system and hindering low-carbon operation.

[0003] Traditional distribution boxes typically employ fixed openings for heat dissipation, making it impossible to dynamically adjust the heat dissipation area based on the number of internal cables and the load. When there are many cables and a heavy load, insufficient heat dissipation leads to increased internal temperature, reducing the efficiency of electrical components and increasing energy consumption. Conversely, when there are few cables and a low load, excessively large openings allow a large amount of dust to enter the box. Dust accumulation increases contact resistance and weakens heat dissipation, creating a vicious cycle of "heat generation—increased losses—even more heat," leaving the distribution box in a suboptimal energy efficiency state for extended periods. This passive cooling method fails to achieve a dynamic balance between heat dissipation efficiency and dust prevention, hindering the achievement of energy conservation and low-carbon goals.

[0004] Existing cable clamps used in distribution boxes generally have limited functionality, only providing simple clamping without adaptive clamping, status feedback, or intelligent interlocking capabilities. The electrical system cannot identify whether cables are properly installed or securely clamped, making them prone to arcing, overheating, and power outages caused by loose cables, posing significant safety hazards. Furthermore, traditional cable clamps cannot adapt to different scenarios, such as distributed multi-strand cables or concentrated large bundles of cables, lacking structural flexibility and scalability, and failing to meet the comprehensive requirements of smart grids for safer, smarter, more energy-efficient, and lower-carbon power distribution equipment. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an energy-saving intelligent distribution box for smart grids, which has the advantages of meeting the comprehensive requirements of smart grids for power distribution equipment in terms of safety, intelligence, energy saving, and low carbon emissions, and solves the problems of the prior art.

[0006] This invention is implemented as follows: an energy-saving intelligent distribution box for smart grids includes a main body and a multi-functional wire clamp module disposed within the main body. The wire clamp module includes: The upper plate is hooked to the inner wall of the main body of the box by a hook-like structure; A pressure plate and a round rod are connected from top to bottom via a transmission connection. A spring clip having an upwardly extending double-ear structure, wherein the double-ear structure and the round rod form a cable clamping position; Two vertical plates are arranged on the left and right sides, and the vertical plates are located on both sides of the spring sheet; Two base plates are respectively installed at the lower end of the vertical plate; And an n-shaped outer frame, wherein the outer side wall of the n-shaped outer frame is provided with a plurality of wire clamps for clamping cables.

[0007] As a preferred embodiment of the present invention, the wire clamp ring is circular and has a locking interface on the side away from the n-shaped outer frame for inserting cables.

[0008] In a preferred embodiment of the present invention, the n-shaped outer frame is arranged in an upright position, the bottom surface of the upper wall of the n-shaped outer frame is in contact with the upper surface of the pressure plate, and the outer side walls of the two vertical plates are respectively in contact with the left and right inner side walls of the n-shaped outer frame.

[0009] In a preferred embodiment of the present invention, the wire clamp module is in a working state without an n-shaped outer frame. A first heat dissipation hole is provided on the main body of the housing, and a heat dissipation slide plate is slidably connected to the outside of the main body of the housing. A second heat dissipation hole is provided on the heat dissipation slide plate. The vertical plate and the heat dissipation slide plate are connected by a transmission rod. When the vertical plate opens outward, the heat dissipation slide plate is driven to slide through the transmission rod, thereby increasing the overlapping area of ​​the first heat dissipation hole and the second heat dissipation hole.

[0010] The more cables clamped on the clamp module, the greater the outward opening of the vertical plate, the larger the overlapping area of ​​the first and second heat dissipation holes, and the stronger the heat dissipation capacity of the distribution box.

[0011] As a preferred embodiment of the present invention, the n-shaped outer frame is arranged in an inverted state, with the bottom of the inverted n-shaped outer frame in contact with the upper surface of the pressure plate, and the wire clamp ring of the n-shaped outer frame is arranged towards the side away from the pressure plate.

[0012] As a preferred embodiment of the present invention, the wire clamp module is installed in an inverted state, with the upper plate still hooked on the side wall of the main body of the box, the spring piece located below the round rod and the arc-shaped supporting surface of the spring piece facing upward, and the two bottom plates located above the spring piece and arranged close to each other. When the cable clamp module is inverted, the bundle of cables is pressed against the arc-shaped support surface of the spring plate. Under the gravity of the bundle of cables, the spring plate deforms downward and drives the two vertical plates to retract inward, so that the two base plates come together and clamp the bundle of cables.

[0013] As a preferred embodiment of the present invention, in the inverted state of the cable clamp module, the n-shaped outer frame is placed above the two base plates, the bottom of the n-shaped outer frame is in contact with the upper surface of the base plates, and the gravity of the n-shaped outer frame acts on the base plates, enhancing the clamping force of the base plates on the cables.

[0014] As a preferred embodiment of the present invention, an electronically controlled switch is provided between the mating surfaces of the two base plates, and the electronically controlled switch is triggered to conduct when the two base plates are mated together.

[0015] As a preferred embodiment of the present invention, the electric control switch is electrically interlocked with the main power supply circuit of the main body of the box. After the electric control switch is turned on, the main power supply circuit of the distribution box is allowed to be switched on and powered on.

[0016] As a preferred embodiment of the present invention, the n-shaped outer frame is provided with a vertically arranged vertical groove, and the side of the wire clamp ring near the n-shaped outer frame is provided with a notch aligned with the vertical groove. The outer surface of the vertical plate is provided with a vertical strip, which can extend into the vertical groove and the notch.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A multi-layer cable management structure is formed by the double-ear structure of the spring clip, the base plate, and the wire clamp ring of the n-shaped outer frame. This achieves orderly cable classification, avoiding poor contact and localized overheating problems caused by traditional messy wiring, and effectively reducing line loss. At the same time, the vertical plate is linked to the heat dissipation slide plate through the transmission rod. The overlapping area of ​​the first heat dissipation hole and the second heat dissipation hole is dynamically adjusted according to the number of cables. The higher the cable load, the better the heat dissipation effect, and the lower the load, the better the dust prevention effect. This avoids ineffective heat dissipation and dust accumulation loss, achieves optimal energy efficiency of the power distribution system, helps to realize the "dual carbon" goal, and is in line with the core development concept of energy saving and low carbon in smart grids.

[0018] 2. The entire clamp module is driven by the weight of the cable and the n-shaped outer frame, without the need for an additional power source. It can achieve automatic clamping and adaptive heat dissipation adjustment, simplifying the structural design, reducing power consumption, and lowering equipment operation and maintenance costs. The hook-shaped structure on the upper plate can be quickly hooked onto the inner wall of the main body of the box, making installation convenient and further improving operation and maintenance efficiency, adapting to the needs of large-scale deployment of smart grids.

[0019] 3. With the n-shaped outer frame in three states—upright, inverted, and removed—and the overall inverted installation design of the wire clamp module, it can flexibly adapt to different scenarios such as distributed multi-strand cables and centralized large bundles of cables. When the wire clamp module is inverted, the spring pieces form an arc-shaped support surface, which, together with the clamping action of the base plate, can stably clamp large bundles of cables. When the n-shaped outer frame is placed inverted on top of the base plate, it can not only supplement the clamping force but also achieve the classification of outer cables, greatly improving the equipment's adaptability and reusability, and reducing the overall investment cost of smart grid power distribution equipment.

[0020] 4. The electrical control switch installed on the mating surface of the two base plates is electrically interlocked with the main power supply circuit of the main body of the box. The electrical control switch is turned on only when the base plates are mated together and the cables are clamped in place, and the distribution box is allowed to be closed and powered on. This effectively avoids safety hazards such as electric arc, overheating and power outage caused by cables not being clamped properly, realizes intelligent detection and interlocking control of cable installation status, and improves the operational stability and safety of the smart grid power distribution system.

[0021] 5. When the n-shaped outer frame is upright, the vertical plate fits tightly against the inner wall of the n-shaped outer frame, achieving a stable fixation between the clamp module and the outer frame; when the clamp module is inverted, the gravity of the n-shaped outer frame can enhance the clamping reliability of the base plate, and the various structures work together to avoid local stress concentration, extend the service life of the clamp module and the distribution box, and reduce the frequency and cost of operation and maintenance of the smart grid distribution system.

[0022] 6. This invention reduces line loss, minimizes ineffective energy consumption, and extends equipment lifespan, thereby reducing the frequency of power distribution equipment replacement and material consumption. At the same time, through adaptive heat dissipation and dustproof design, it reduces the probability of equipment failure and reduces energy consumption and carbon emissions during operation and maintenance, fully meeting the low-carbon development requirements of smart grids.

[0025] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 11 As shown in the figure, an energy-saving smart distribution box for smart grids provided by an embodiment of the present invention includes a box body 1 and a multi-functional wire clamp module disposed within the box body 1. The wire clamp module includes: an upper plate 2, which is hooked to the inner side wall of the box body 1 by a hook-like structure 14; a pressure plate 3 and a round rod 4, which are connected from top to bottom; a spring piece 5, which has an upwardly extending double-ear structure 15, and the double-ear structure 15 and the round rod 4 form a cable clamping position; two vertical plates 6 arranged on the left and right sides, which are located on both sides of the spring piece 5; two bottom plates 7 respectively disposed at the lower end of the vertical plates 6; and an n-shaped outer frame 8, the outer side wall of which is provided with a plurality of wire clamp rings 16 for clamping cables.

[0028] Firstly, addressing the issue of "cumbersome installation and inability to quickly fix traditional wire clamps," the hook-like structure of the upper plate 2 allows the entire multi-functional wire clamp module to be quickly hooked onto the inner wall of the main body 1 of the enclosure without the need for additional fasteners. This enables convenient and stable installation of the wire clamp module, solving the problems of low installation efficiency and unreliable fixation of traditional wire clamps, and providing a stable benchmark for subsequent cable management and functional implementation.

[0029] Secondly, addressing the pain point in the background technology of "traditional distribution boxes having messy cables and lacking layering and classification, which easily leads to poor contact and localized overheating", the cable clamp module achieves orderly cable storage through the cooperation of its various structures: the double-ear structure of the spring piece 5 and the round rod 4 form a dedicated cable clamping position, which can store some scattered cables; the base plate 7 can serve as an auxiliary cable clamping structure to store another part of the cables; the several cable clamping rings on the outer wall of the n-shaped outer frame 8 can realize the classification and clamping of the outer layer cables. The three work together to form a multi-layer cable storage structure, fundamentally solving the problem of messy cable stacking in traditional distribution boxes, avoiding poor contact and localized overheating that cause line loss and increased energy consumption, and meeting the energy-saving requirements of smart grids. Furthermore, addressing the pain point in the background technology that "traditional wire clamps can only perform simple clamping and lack the basis for adaptive adjustment," a force transmission channel is constructed through the transmission connection between the pressure plate 3 and the round rod 4, providing a foundation for subsequent adaptive clamping, heat dissipation adjustment, and other functions. The spring piece 5 has elastic deformation capability and can drive the vertical plates 6 on both sides to move after being subjected to force. The vertical plates 6, as the force output end, can not only cooperate with the n-shaped outer frame 8 to achieve automatic clamping of cables, but also link with the subsequent heat dissipation structure, solving the shortcomings of traditional wire clamps that are single in function and unable to achieve adaptive adjustment. Finally, this provides an expanded foundation for addressing pain points in the background technology, such as the contradiction between heat dissipation and dust prevention, and the lack of intelligent interlocking: the cooperation of the main body 1, vertical plate 6, heat dissipation slide plate 9, first heat dissipation hole 10, second heat dissipation hole 11, and transmission rod 12 can realize subsequent load adaptive heat dissipation adjustment; the cooperation of the bottom plate 7 and the electric control switch 13 can realize intelligent interlocking of cable installation status, providing structural support for the energy-saving, low-carbon, and safe operation of the smart grid.

[0030] The wire clamp ring 16 is circular and has a card interface 17 on the side away from the n-shaped outer frame 8 for inserting cables.

[0031] Method 1: The n-shaped outer frame 8 is arranged in an upright position. The bottom surface of the upper wall of the n-shaped outer frame 8 is in contact with the upper surface of the pressure plate 3. The outer walls of the two vertical plates 6 are respectively in contact with the left and right inner walls of the n-shaped outer frame 8. When the n-shaped outer frame 8 is upright, its top is in contact with the pressure plate 3. The weight of the n-shaped outer frame 8 and the cable together presses down on the pressure plate 3, and the pressure is transmitted to the spring piece 5 through the round rod 4. The spring piece 5 is forced to open the two vertical plates 6 outward, so that the outer walls of the vertical plates 6 are pressed against the inner walls of the n-shaped outer frame 8, realizing automatic clamping and fixing.

[0032] Method 2: The wire clamp module is in a working state without the n-shaped outer frame 8. The main body 1 of the box has a first heat dissipation hole 10. A heat dissipation plate 9 is slidably connected to the outside of the main body 1. The heat dissipation plate 9 has a second heat dissipation hole 11. The vertical plate 6 and the heat dissipation plate 9 are connected by a transmission rod 12. When the vertical plate 6 opens outward, the transmission rod 12 drives the heat dissipation plate 9 to slide, thereby increasing the overlapping area of ​​the first heat dissipation hole 10 and the second heat dissipation hole 11.

[0033] The more cables clamped on the clamp module, the greater the outward opening of the vertical plate 6, the larger the overlapping area of ​​the first heat dissipation hole 10 and the second heat dissipation hole 11, and the stronger the heat dissipation capacity of the distribution box.

[0034] When the wire clamp module does not use the n-type outer frame 8, it can work independently. The main body 1 of the housing has a first heat dissipation hole 10, and a heat dissipation slide plate 9 is slidably installed on the outside. The heat dissipation slide plate 9 has a second heat dissipation hole 11. The vertical plate 6 is connected to the heat dissipation slide plate 9 through a transmission rod 12. When the vertical plate 6 opens outward, it pushes the heat dissipation slide plate 9 to move, increasing the overlapping area of ​​the first heat dissipation hole 10 and the second heat dissipation hole 11, thereby improving the heat dissipation capacity.

[0035] Method 3: The n-shaped outer frame 8 is arranged in an inverted state, with its bottom contacting the upper surface of the pressure plate 3. The wire clamp 16 of the n-shaped outer frame 8 faces away from the pressure plate 3. The inverted arrangement of the n-shaped outer frame 8, with its bottom still in contact with the pressure plate 3, provides downward pressure to drive the internal mechanism. The wire clamp 16 faces outwards, facilitating cable clamping and preventing interference between the frame structure and the movement of the vertical plate 6.

[0036] Method 4: The wire clamp module is installed in an inverted state. The upper plate 2 is still hooked on the side wall of the main body 1 of the box. The spring piece 5 is located below the round rod 4 and the arc-shaped support surface of the spring piece 5 is arranged upward. The two bottom plates 7 are located above the spring piece 5 and are arranged close to each other. When the cable clamp module is inverted, the bundle of cables is pressed against the arc-shaped support surface of the spring plate 5. The spring plate 5 deforms downward under the gravity of the bundle of cables and drives the two vertical plates 6 to retract inward, so that the two bottom plates 7 come together and clamp the bundle of cables.

[0037] The cable clamp module is installed upside down, with the upper plate 2 still hooked to the inner wall of the main body 1 for fixation. The curved support surface of the spring plate 5 faces upwards to support the large bundle of cables. The weight of the cables presses down on the spring plate 5, causing it to deform and drive the vertical plate 6 to retract inwards, thereby bringing the two bottom plates 7 closer together and automatically clamping the large bundle of cables.

[0038] Method 5: With the cable clamp module in an inverted state, the n-shaped outer frame 8 is placed on top of the two base plates 7. The bottom of the n-shaped outer frame 8 is in contact with the upper surface of the base plate 7. The gravity of the n-shaped outer frame 8 acts on the base plate 7, enhancing the clamping force of the base plate 7 on the cable.

[0039] With the cable clamp module in an inverted position, the n-shaped outer frame 8 can be placed on top of the base plate 7. The gravity of the n-shaped outer frame 8 further acts on the base plate 7, improving clamping reliability. The n-shaped outer frame 8 can also clamp the outer layer of distributed cables, achieving multi-layer classified storage.

[0040] Furthermore, an electric control switch 13 is provided between the mating surfaces of the two base plates 7. When the two base plates 7 are mated together, the electric control switch 13 is activated. The electric control switch 13 is electrically interlocked with the main power supply circuit of the main body 1 of the enclosure. After the electric control switch 13 is activated, the main power supply circuit of the distribution box is allowed to be switched on and energized.

[0041] An electric control switch 13 is installed between the mating surfaces of the two base plates 7. When the base plates 7 are fully mated under the pressure of the cable, the electric control switch 13 is triggered to conduct. The electric control switch 13 is connected to the main power supply circuit of the distribution box. The distribution box is only allowed to be powered on when the switch is turned on, that is, after the cable is installed in place and clamped, so as to achieve safety interlocking.

[0042] Furthermore, the n-shaped outer frame 8 is provided with a vertically arranged groove 18, and the wire clamp 16 has a notch 19 aligned with the groove 18 on the side near the n-shaped outer frame 8. The outer surface of the vertical plate 6 is provided with a vertical strip 20, which extends into the groove 18 and the notch 19. This design makes the n-shaped outer frame 8 more secure and less prone to detachment. Furthermore, the vertical strip 20, extending into the groove 18 and the notch 19, can contact the wire in the wire clamp 16, thereby clamping it to a certain extent and preventing it from shaking.

[0043] Working principle of the invention: The multi-functional cable clamp module is fixed to the inside of the main body 1 of the box via the upper plate 2. The weight of the cable and the n-shaped outer frame 8 is used as the driving force, which is transmitted to the spring piece 5 through the pressure plate 3 and the round rod 4, driving the vertical plate 6 to move, realizing the layered storage and self-adaptive clamping of the cable. The vertical plate 6 is linked with the heat dissipation slide plate 9 to adjust the overlapping area of ​​the first heat dissipation hole 10 and the second heat dissipation hole 11, balancing heat dissipation and dust prevention. The bottom plate 7 is attached to the trigger electric control switch 13 to realize the interlock with the main power supply circuit. There is no additional power throughout the process, which solves the pain points of traditional distribution boxes such as messy cables, unbalanced heat dissipation, and safety hazards, and realizes energy-saving, safe and self-adaptive operation.
