Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a primary and secondary integrated power ring network box. Background Technology

[0002] With the development of smart grids, the requirements for the intelligent integration of power distribution equipment are becoming increasingly stringent. A ring main unit (RNB) is a set of power transmission and distribution equipment housed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. Existing integrated primary and secondary ring main units mainly include a data acquisition terminal, busbar unit, incoming line unit, and feeder unit. All incoming line units and feeder units use standardized interface designs for power supply, current, remote signaling, and remote control circuits, which are then connected to the data acquisition terminal unit's connector compartment via secondary aviation connectors. However, the equipment and components inside existing integrated primary and secondary power ring main units are fixedly installed on a frame inside the box, which poses challenges when maintenance is required. During maintenance, personnel need to repeatedly extend their bodies into the enclosure and adjust their positions, making it extremely inconvenient to inspect and replace internal equipment. Furthermore, the existing integrated primary and secondary power ring main units have limited internal space. Once the space is filled by the installed incoming and outgoing cabinets, it's impossible to add auxiliary equipment like data transmission units later, limiting the performance of the existing integrated primary and secondary power ring main units. Additionally, their poor heat dissipation prevents sufficient heat dissipation. Therefore, a new integrated primary and secondary power ring main unit is needed to solve these problems. Summary of the Invention

[0014] The beneficial effects of this invention are:

[0015] I. This invention utilizes the sliding engagement of the movable installation unit and the sliding limit slot, along with the quick-release structure of the locking block and locking slot of the limit part, to allow each movable installation unit to be completely and independently pulled out from either side of the enclosure. The equipment is fully exposed outside the enclosure, allowing maintenance personnel to work without having to enter the enclosure. This solves the problem of limited maintenance space and inconvenient operation in traditional ring main units. The first and second space extensions use a foldable corrugated folding box with a movable adjustment frame. In the folded state, it does not occupy extra space, and when unfolded, it can flexibly increase the installation volume at both ends of the enclosure to meet the expansion needs of adding data transmission units and other equipment later. Furthermore, the positioning structure of the limit support plate, sliding support block, and locking threaded column, as well as the rolling support of the support rollers, ensure that the expanded structure is stable, reliable, and easy to adjust.

[0016] II. This invention employs a multi-mode heat dissipation system, including active bottom-blowing of the cooling fan, a heat dissipation channel formed by wiring channels and mounting holes, powerful exhaust from the top of the exhaust fan, and natural convection assisted by the first and second heat dissipation holes. This achieves efficient heat dissipation from the bottom up, effectively preventing internal heat accumulation. The protective cover and inclined baffles respectively provide rain protection and guide the top and side heat dissipation holes, balancing heat dissipation and waterproofing performance, adapting to harsh outdoor weather. The mounting holes and wiring channels ensure neat and orderly equipment installation and wiring. The mounting base provides a fixed foundation for additional equipment, significantly improving the overall performance and expansion flexibility of the ring main unit, and reducing the maintenance and replacement costs throughout the equipment's lifecycle.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] The invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 1-4As shown, a primary and secondary integrated power ring network box of the present invention includes a first spatial extension 2, a support base 3, a box body 4, a first rotating door 5, a second rotating door 6, a second spatial extension 7, a first fixing bolt 8, an exhaust fan 9, a first heat dissipation hole 10, a movable installation unit 11, a limiting part 12, and a sliding limiting groove 13. The support base 3 is fixedly connected to the bottom end of the box body 4. The first rotating door 5 is rotatably disposed on both sides of the box body 4. The second rotating door 6 is rotatably connected to the first rotating door 5. The first spatial extension 2 and the second spatial extension 7 are respectively disposed at both ends of the box body 4. The first spatial extension 2 and the second spatial extension 7 have the same structure. The first heat dissipation hole 10 is evenly and uniformly opened through the box body 4. The exhaust fan 9 is evenly and fixedly installed in the upper middle part of the box body 4. The first fixing bolt 8 is evenly threaded into both ends of the upper part of the box body 4. The sliding limiting groove 12... 3 are evenly distributed at the top and bottom of the housing 4. The limiting part 12 is evenly and symmetrically distributed at the bottom of the housing 4. The movable installation unit 11 is evenly distributed inside the housing 4. The upper end of the housing 4 is fixedly installed with a partition protective cover 1, which is located above the exhaust fan 9 and the first heat dissipation hole 10. The two sides of the partition protective cover 1 are inclined downwards. After the first rotating door 5 and the second rotating door 6 on both sides of the housing 4 are opened, the movable installation unit 11 inside can be arbitrarily slid out from one side of the housing 4, so that the equipment installed in different positions inside the movable installation unit 11 can be easily repaired and replaced. The partition protective cover 1 plays a role in blocking rainwater flow and preventing rainwater from entering the housing 4. The first space extension part 2 and the second space extension part 7 can increase the overall installation space inside the housing 4.

[0030] like Figure 5As shown, the movable installation unit 11 includes a locking slot 14, a first sliding bracket 15, mounting holes 18, a wiring groove 19, a pull-out groove 20, a mounting plate 21, a side support plate 22, and a second sliding bracket 23. The side support plates 22 are symmetrically distributed. The second sliding bracket 23 is fixedly connected to the upper ends of the side support plates 22, and the first sliding bracket 15 is fixedly connected to the bottom ends of the side support plates 22. The locking slot 14 is evenly opened on both sides of the first sliding bracket 15. The mounting plate 21 is evenly fixedly installed inside the side support plates 22. The pull-out groove 20 is opened through the middle of both ends of the mounting plate 21. The mounting holes 18 are evenly opened through the middle of both ends of the mounting plate 21. The wiring channel 19 is provided on the mounting plate 21 and the side support plate 22. The mounting frame 16 is fixedly installed at the upper middle part of the first sliding bracket 15. The cooling fan 17 is evenly fixedly installed on the mounting frame 16 and is located directly below the mounting plate 21. The equipment can be easily installed through the mounting holes 18 provided on the mounting plate 21 and the side support plate 22. The wiring channel 19 facilitates wiring and heat dissipation. The cooling fan 17 can fully dissipate heat from the bottom of the equipment installed on the movable mounting unit 11. With the help of the exhaust fan 9, the heat inside the housing 4 can be fully discharged and dissipated.

[0031] like Figure 6 As shown, the limiting part 12 includes a movable plate 24, a reset support spring 25, a support fixing plate 26, a control handle 27, and a locking block 28. The movable plate 24 is disposed inside the support fixing plate 26. The reset support spring 25 is evenly fixedly installed between the support fixing plate 26 and the movable plate 24. The control handle 27 is fixedly connected to both ends of the movable plate 24. The locking block 28 is evenly fixedly connected to the bottom of the side end of the movable plate 24 away from the support fixing plate 26. By controlling the handle 27, the movable plate 24 presses the reset support spring 25, thereby causing the locking block 28 to be pulled out from the locking slot 14. This allows the movable installation unit 11 at the designated position to slide out from any side of the housing 4 for equipment maintenance and replacement inside the movable installation unit 11.

[0032] like Figures 7-8As shown, the second space extension 7 includes a movable adjustment frame 29, a limiting support plate 30, a corrugated folding box 31, a locking threaded post 32, a sliding support block 33, a mounting base 36, and a second heat dissipation hole 38. The corrugated folding box 31 is fixedly connected to the outer end of the movable adjustment frame 29. The limiting support plate 30 is symmetrically fixedly installed at both ends of the movable adjustment frame 29. The sliding support block 33 is fixedly connected to the outer ends of both ends of the corrugated folding box 31, and the limiting support plate 30 is slidably inserted into the interior of the sliding support block 33. The locking threaded post 32 is threadedly rotated on the sliding support block 33, and the bottom end of the locking threaded post 32 is pressed against the outer wall of the sliding support block 33. The mounting base 36 is symmetrically fixedly installed inside the movable adjustment frame 29. The movable adjustment frame 29 in the second space extension 7 and the first space extension 2 can slide outward along the box body 4 to adjust the installation space, and the corrugated folding box 31... 1. The corrugated folding box 31 can be opened in a folded state by external pulling, which allows for the adjustment of the movable adjustment frames 29 at both ends of the box body 4 and the internal installation space of the corrugated folding box 31 to be increased and adjusted accordingly. The sliding support block 33 slides along the limiting support plate 30, which makes the corrugated folding box 31 firmly and stably opened. The sliding support block 33 can be locked and fixed on the limiting support plate 30 by screwing the locking threaded column 32. The corrugated folding box 31 adopts a corrugated foldable structure, including multiple corrugated folding units. The corrugated folding units are connected in sequence to form a folding box body that can be stretched and retracted in the horizontal direction. The material of the corrugated folding box 31 is preferably metal, specifically 304 stainless steel plate or corrugated stainless steel plate. The wall thickness of the corrugated folding box 31 is preferably 1.0mm-2.0mm, and the height difference between the crest and trough of the corrugated folds is preferably 30mm-80mm to ensure sufficient extension stroke and structural strength.

[0033] The outer side of the corrugated folding box 31 is evenly provided with second heat dissipation holes 38. An inclined baffle 34 is fixedly installed at the outer end of the corrugated folding box 31, and the inclined baffle 34 is located above the second heat dissipation holes 38. The second heat dissipation holes 38 assist in heat dissipation, and the inclined baffle 34 serves to waterproof the box.

[0034] A support base plate 35 is provided below the movable adjustment frame 29 and the corrugated folding box 31. Support rollers 37 are evenly rotated and installed on the support base plate 35, and the upper end of the support rollers 37 contacts the bottom support of the movable adjustment frame 29 and the corrugated folding box 31. The bottom of the movable adjustment frame 29 and the corrugated folding box 31 that are slid outward can be supported by the support rollers 37.

[0035] The movable adjustment frame 29 is slidably engaged with the outer end of the housing 4, and the bottom end of the first fixing bolt 8 is pressed against the movable adjustment frame 29, which can lock the movable adjustment frame 29 in place, and the supporting base plate 35 is fixedly connected to the housing 4.

[0036] The support plate 26 is fixedly connected to the bottom of the box 4. The second sliding bracket 23 and the first sliding bracket 15 are slidably engaged in the sliding limit slot 13 set inside the box 4, which can realize sliding movement adjustment. The locking block 28 is engaged in the inside of the locking slot 14 to realize locking and fixing.

[0037] Working principle: Multiple movable installation units 11 are evenly distributed inside the enclosure 4. Each movable installation unit 11 is slidably engaged in the sliding limit slot 13 opened inside the enclosure 4 via the first sliding bracket 15 and the second sliding bracket 23 at its bottom. Components and equipment are fixedly installed on the mounting plate 21 through the mounting holes 18. The mounting plate 21 is evenly fixedly installed between the side support plates 22. The connecting cables between the equipment are arranged through the wiring channel 19 to ensure that the wiring is neat and orderly. When it is necessary to repair or replace the equipment in a specific position inside the enclosure 4, the operator presses the movable plate 24 through the control handle 27, so that the movable plate 24 is moved. The spring force of the reset support spring 25 moves the fixed plate 26 towards the support plate 26. During the movement of the moving plate 24, the locking blocks 28 fixedly connected at both ends are pulled out from the locking slots 14. At this time, the operator can slide the moving installation unit 11 out from either side of the housing 4, i.e., the first rotating door 5 and the second rotating door 6, along the sliding limit slot 13. After the moving installation unit 11 is pulled out, the equipment is completely exposed outside the housing, which is convenient for the operator to carry out maintenance and replacement work. After the maintenance is completed, the moving installation unit 11 is pushed back to its original position. The locking blocks 28 automatically engage in the locking slots 14 under the action of the reset support spring 25 to complete the locking.

[0038] When the internal installation space of the housing 4 is insufficient, the space can be expanded through the second space extension 7 and the first space extension 2. The operator pulls the movable adjustment frame 29 outward, which causes the corrugated folding box 31 to slide outward along the limiting support plate 30. The corrugated folding box 31 is compact in the folded state and does not occupy extra space. It can be opened from the folded state under external force, so that the movable adjustment frames 29 at both ends of the housing 4 and the internal installation space of the corrugated folding box 31 can be appropriately increased and adjusted. After adjustment, the locking threaded post 32 is screwed on to make the bottom end of the locking threaded post 32 press against the outer wall of the limiting support plate 30, thus realizing sliding. The support block 33 is locked and fixed on the limiting support plate 30 to ensure the stability and reliability of the expanded space. A support base plate 35 is provided below the movable adjustment frame 29 and the corrugated folding box 31. Support rollers 37 are evenly rotated and installed on the support base plate 35. The upper end of the support rollers 37 is in contact with the bottom support of the movable adjustment frame 29 and the corrugated folding box 31. The support rollers 37 can stably support the bottom of the movable adjustment frame 29 and the corrugated folding box 31 that are slid outward, reducing sliding friction. The movable adjustment frame 29 is slidably engaged with the outer end of the box body 4. The bottom end of the first fixing bolt 8 is pressed and contacted with the movable adjustment frame 29, which can lock and fix the movable adjustment frame 29.

[0039] The cooling fans 17, which are uniformly fixed on the mounting plate 21, are located directly below the mounting plate 21. They actively blow air from the bottom to cool the equipment installed on the mobile mounting unit 11. The heat flows upward through the wiring grooves 19 and mounting holes 18 on the mobile mounting unit 11. The exhaust fan 9, which is uniformly fixed in the middle of the upper part of the box 4, exhausts the hot air inside the box 4 to the outside. The first heat dissipation holes 10, which are uniformly opened through the box 4, assist in natural convection cooling. The partition protective cover 1 is located above the exhaust fan 9 and the first heat dissipation hole 10, and the two sides of the partition protective cover 1 are inclined downward to block rainwater and prevent rainwater from entering the box 4. The second heat dissipation holes 38, which are uniformly opened through the outer side of the corrugated folding box 31, assist in heat dissipation. The inclined partition 34 is located above the second heat dissipation holes 38 and serves as a waterproofing measure.
