Description

Technical Field

[0001] This utility model belongs to the technical field of outdoor power distribution boxes, and particularly relates to a compact outdoor power distribution box device. Background Technology

[0002] Outdoor distribution boxes are an indispensable basic equipment in power transmission and distribution systems. They are widely used in various fields such as cities, villages, industrial parks, public facilities, traffic lighting, communication base stations, and new energy (such as charging piles). They undertake the core functions of power distribution, circuit protection (overload, short circuit), metering, monitoring, and providing power interfaces for terminal equipment.

[0003] With the acceleration of urbanization, the dense deployment of infrastructure (such as 5G micro base stations, electric vehicle charging piles, and smart streetlights), the renovation and upgrading of old urban areas, and the increasing scarcity of land resources, the space available for installing power distribution equipment (such as narrow alleys, building exteriors, streetlights, and limited ground space) is becoming increasingly precious and limited.

[0004] Against this backdrop, the market has placed core demands on outdoor distribution boxes to be miniaturized, lightweight, and compact. Traditional standard-sized distribution boxes are often bulky, difficult to install, detract from the aesthetics of the cityscape, and may even fail to meet the space requirements of specific scenarios.

[0005] Based on the above analysis, the problems and shortcomings of the existing technology are as follows: (1) Large size and large space occupation. Traditional outdoor distribution box design focuses on versatility and internal operating space, resulting in a large overall size. It is difficult or unsightly to install in space-constrained areas (such as narrow streets, dense equipment areas, and building facades).

[0006] (2) Low internal space utilization. The internal layout is not optimized, the component installation method (such as standard guide rail laying) occupies a large area, and there is a lot of ineffective space inside the box, resulting in "large box, small capacity". Utility Model Content

[0007] To overcome the problems existing in related technologies, the present invention discloses a compact outdoor power distribution box device.

[0008] The technical solution is as follows: a compact outdoor distribution box device, the device including an outdoor box shell for isolating the ring main unit from the external environment, the ring main unit being structurally fitted and integrated with the outdoor box shell; The outdoor enclosure includes a top cover, an upper door panel, a pneumatic spring rod, vertical beams, and a hinge structure. The upper door panel of the housing is hinged to the top cover of the housing via a hinge structure; one end of the pneumatic spring rod is fixed to the upper door panel of the housing, and the other end is fixed to the vertical beam of the cabinet; the pneumatic spring rod opens and closes the upper door panel of the housing through pneumatic action.

[0009] Furthermore, the outdoor enclosure adopts a split structure, with the internal cavity size matching the outer contour of the ring main unit. It can be detachably fitted onto the outside of the ring main unit through the enclosure base, cabinet vertical beams, and cabinet fixing plates. The outdoor enclosure completely covers the left, right, and top sides of the ring main unit.

[0010] Annular heat dissipation ducts are provided at the front, back, left, and right sides between the outdoor enclosure and the ring main unit.

[0011] The ring main unit consists of a cable working compartment, a switch compartment, a mechanism compartment, a control compartment, a control compartment panel, a mechanism compartment panel, and a cable working compartment door. The cable working compartment of the cabinet is located at the lower end of the outdoor box shell. The cabinet mechanism room is installed at the upper front of the cable working compartment, the cabinet switch room is installed at the upper rear of the cable working compartment, and the cabinet control room is installed above the cabinet mechanism room. The front face of the cabinet mechanism compartment is equipped with a mechanism compartment panel; the front face of the cabinet control compartment is equipped with a control compartment panel; and the front of the cabinet cable work compartment is equipped with a cable work compartment door.

[0012] Furthermore, the outdoor enclosure also includes a left side panel, a lower door panel, a lower door panel mounting beam, a base, a latch, a lower rear cover, a right side panel, a middle crossbeam, a lifting device, an upper rear cover, a cabinet fixing plate, a fault indicator box, a power supply device, and a ring network cable tray, all of which are connected together by assembly.

[0013] The pneumatic spring rod is composed of a pneumatic telescopic rod, a pneumatic cylinder, and a fixed bending plate.

[0014] The hinge structure includes a fixed hinge, which is fixed to the top cover of the housing by a fixing stud; The fixed hinge is hinged to the rotating hinge via a hinge pin, and the rotating hinge is fixed to the upper door panel of the housing via a fixing stud.

[0015] The exterior of the shell top cover adopts an inclined top structure, and the interior of the shell top cover is welded with reinforcing ribs and fitted with insulation cotton.

[0016] The lower door panel of the housing is fixed together by welding the lower door panel, left latch, right latch, operating handle fixing bracket, data box, and lower door limit plate. The latch consists of a latch body bent plate, a latch body fixing device, and a latch body lock. After maintenance is completed and the upper door panel of the housing is closed, the latch will fix the upper door panel of the housing to the left side panel and the right side panel of the housing respectively. Louvers are designed on the lower rear cover plate and the upper rear cover plate of the housing. The crossbeam in the shell fixes the rear middle part of the outdoor box shell, and fixes the rear lower cover plate and the rear upper cover plate of the shell together; The lifting devices are installed on both sides of the outdoor enclosure. The fault indicator box, power supply device, and ring network cable tray are installed on the left side of the outdoor box casing.

[0017] Combining all the above technical solutions, the beneficial effects of this utility model are as follows: In the renovation of urban power distribution networks and the expansion of old residential areas, this utility model solves the problem that due to extremely limited space, standard distribution boxes cannot be installed in old urban areas, narrow alleys, and densely populated residential areas, resulting in insufficient power supply capacity or obstruction of renovation projects.

[0018] In municipal facilities (streetlights, traffic signals, monitoring), this utility model meets the demand for miniaturized and lightweight distribution boxes for streetlight poles, traffic signal control boxes, and power supply points for monitoring equipment. It facilitates concealed installation, reduces the impact on the landscape, and lowers the load requirements on the supporting structure (light pole).

[0019] In the field of new energy charging infrastructure, this utility model provides a highly integrated and minimally sized supporting power distribution protection unit for distributed, low-power AC charging piles, which can be flexibly deployed in parking lot corners and roadside limited spaces.

[0020] In industrial parks and for new equipment installations, this invention provides a convenient power source for new equipment (such as small machinery and sensor networks) within the factory area, eliminating the need to occupy large spaces for installing large power distribution cabinets. The miniaturized design saves on material costs, transportation costs, and installation foundation costs; the optimized maintenance design reduces subsequent operation and maintenance costs and time.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Example 1: The compact outdoor distribution box adopts a top-flip cover structure, which differs from the traditional double-door outdoor box mechanism. Compared with the traditional double-door, the upper door panel 12 (top-flip cover) reduces the number of hinges by 50% and eliminates the door gap alignment problem. The top-flip cover does have unique advantages in the field of outdoor boxes. Firstly, in terms of protection, the top hinge allows the door panel to naturally form an "eaves effect," allowing rainwater to flow away along the direction of gravity, making it easier to achieve IP65 than side-opening doors. Secondly, maintenance personnel do not need to bend over to operate, which is ergonomic (the door panel opens upwards by 90°-110°, providing a vertical, unobstructed operating space, allowing maintenance personnel to operate upright).

[0024] The top-opening structure effectively solves the industry's pain points, especially its adaptability to narrow spaces—the top-opening structure does not occupy the side passage when opened, which is crucial for installation in urban alleyways. It does not encroach on the passages on both sides of the cabinet when opened (compared to side-opening doors, which require ≥60° swing space).

[0025] The pneumatic spring rod 13 provides continuous support, preventing the door panel from suddenly closing and injuring people during strong winds or vibrations.

[0026] The hinge structure 25 is located at the top of the enclosure, away from the splashing of mud and water from the ground, reducing the risk of rust and jamming.

[0027] Specifically, Figures 1-9 As shown, the compact outdoor power distribution box device includes an outdoor box housing 1 and a ring main unit 2. The ring main unit 2, as the core electrical module, undertakes the power supply function, while the outdoor box housing 1, as the environmental protection module, realizes the all-round environmental isolation of the ring main unit 2. The two are integrated and assembled through structural splicing to form a compact power distribution device.

[0028] like Figure 3 The outdoor enclosure 1 adopts a split structure, and its internal cavity dimensions match the outer contour of the ring main unit 2. It is detachably fitted onto the outside of the ring main unit 2 via the enclosure base 17, cabinet vertical beams 14, and cabinet fixing plate 24. After assembly, the outdoor enclosure 1 completely covers the left, right, and top sides of the ring main unit 2, forming a sealed environmental protection system. Meanwhile, the control room panel 7, mechanism room panel 8, and cable work compartment door 9 on the ring main unit 2 can still be independently opened / closed for equipment operation. Figure 2 As shown; A ring-shaped heat dissipation duct of ≥50mm is maintained between the outdoor enclosure 1 and the ring main unit 2 in the front, back, left, and right directions (the heat dissipation duct is not shown in the schematic diagram) to ensure heat exchange efficiency.

[0029] like Figure 2The ring main unit 2 consists of a cable working compartment 3, a switch compartment 4, a mechanism compartment 5, a control compartment 6, a control compartment panel 7, a mechanism compartment panel 8, and a cable working compartment door 9. The ring main unit 2 is designed in a compact and modular manner according to the functional area division, which in turn allows the outdoor enclosure 1 to be designed in a compact and modular manner.

[0030] The cabinet cable working compartment 3 is located at the lower end of the outdoor box shell 1. The cabinet mechanism chamber 5 is installed at the upper front part of the cabinet cable working compartment 3, the cabinet switch chamber 4 is installed at the upper rear part of the cabinet cable working compartment 3, and the cabinet control chamber 6 is installed at the upper part of the cabinet mechanism chamber 5. The front face of the cabinet mechanism compartment 5 is equipped with a mechanism compartment panel 8; the front face of the cabinet control compartment 6 is equipped with a control compartment panel 7; the front of the cabinet cable work compartment 3 is equipped with a cable work compartment door 9. like Figure 3 The outdoor enclosure 1 is composed of an enclosure top cover 10, an enclosure left side panel 11, an enclosure upper door panel 12, a pneumatic spring rod 13, a cabinet vertical beam 14, an enclosure lower door panel 15-1, a lower door panel mounting beam 16, an enclosure base 17, a buckle 18, an enclosure rear lower cover 19, an enclosure right side panel 20, an enclosure middle crossbeam 21, a lifting device 22, an enclosure rear upper cover 23, a cabinet fixing plate 24, a hinge structure 25, a fault indicator box 26, a power supply device 27, and a ring network cable tray 28, which are connected together by assembly.

[0031] like Figure 4 The upper door panel 12 of the housing is fixedly connected to the top cover 10 of the housing by a fixed hinge 25-1, and the upper door panel 12 of the housing is opened and closed under the action of the pneumatic spring rod 13.

[0032] like Figure 5 As shown, the pneumatic spring rod 13 is composed of a pneumatic telescopic rod 13-1, a pneumatic cylinder 13-2, and a fixed bending plate 13-3.

[0033] The pneumatic spring rod 13 (also known as a gas spring, gas support rod, or pneumatic rod) is a mechanical device that uses compressed gas to store and release energy to achieve controllable linear motion. Its core function is to provide stable support force, buffer force, and position holding capability for equipment.

[0034] like Figure 6 The hinge structure 25 is used to movably hinge the upper door panel 12 of the housing to the top cover 10 of the housing. The hinge structure 25 specifically includes a fixed hinge 25-1, a hinge pin 25-2, a swivel hinge 25-3, and a fixed stud 25-4; The fixed hinge 25-1 is fixed to the top cover 10 of the housing by the fixed stud 25-4; The fixed hinge 25-1 is hinged to the rotating hinge 25-3 via the hinge pin 25-2, and the rotating hinge 25-3 is fixed to the upper door panel 12 of the housing via the fixing stud 25-4.

[0035] The exterior of the housing top cover 10 adopts an inclined top design (inclination angle > 10°) to ensure that rainwater, dew, and dust on the top cover can quickly slide off. Reinforcing ribs are welded inside the housing top cover 10 to ensure its strength. An insulating cotton layer is installed inside the housing top cover 10 to insulate the internal core electrical modules. Simultaneously, the insulating cotton can absorb condensation droplets, and the inclined top structure prevents condensation droplets from dripping vertically, effectively protecting the core electrical modules.

[0036] like Figure 8 As shown, the lower door panel 15 of the housing is fixed together by welding together the lower door panel 15-1, the left latch 15-2, the right latch 15-3, the operating handle fixing bracket 15-4, the data box 15-5, and the lower door limit plate 15-6. The lower door panel 15-1 is a major component of the lower door panel 15 of the housing, serving as the main protective element of the outdoor enclosure 1. The data box 15-5 is mainly used to store data of the power distribution equipment. The operating handle fixing bracket 15-4 is used to fix the operating wrench of the power distribution equipment and is located at the front of the cabinet for easy operation by maintenance personnel. The lower door limiting plate 15-6 and the lower door panel mounting beam 16 are connected by a plug-in connection, tightly attaching the lower part of the lower door panel 15 to the bent edges of the left side panel 11 and the right side panel 20 of the housing. The left pin 15-2 and the right pin 15-3 are the most critical components of the lower door panel 15. After the lower door limiting plate 15-6 is inserted into the limiting hole of the lower door panel mounting beam 16, the cylindrical rods on the left pin 15-2 and the right pin 15-3 respectively block the inner edge of the bent plate of the left side panel 11 and the right side panel 20 of the housing, ensuring that the lower door panel 15 is reliably fixed to the outdoor enclosure 1.

[0037] like Figure 7 As shown, the latch 18 is composed of a latch body bending plate 18-1, a latch body fixing device 18-2, and a latch body lock 18-3. After the maintenance is completed and the upper door panel 12 of the housing is closed, the latch 18 is used to fix the upper door panel 12 of the housing to the left side panel 11 and the right side panel 20 of the housing, respectively.

[0038] Louvers are designed on the lower rear cover plate 19 and the upper rear cover plate 23 of the housing to provide ventilation and heat dissipation for the power distribution equipment and protect the safe operation of the power distribution equipment.

[0039] like Figure 3 The crossbeam 21 in the shell fixes the rear middle part of the outdoor box shell 1, supports the entire frame, and also serves as a fixed connection between the lower rear cover plate 19 and the upper rear cover plate 23 of the shell.

[0040] The lifting device 22 is installed on both sides of the outdoor housing 1 for easy lifting.

[0041] The fault indicator box 26, power supply device 27, and ring network cable tray 28 are respectively installed on the left side of the outdoor box shell 1, which play a role in fixing, limiting and protecting the secondary components.

[0042] Working principle: (1) Power outage maintenance; Open the latch 18-3 with the key → open the upper door panel 12 of the housing and limit the latch 18 → open the upper door panel 12 of the housing upwards → operate the ring main unit 2 to open the circuit breaker, load switch or disconnect switch, and grounding switch. After confirming that the ring main unit 2 is completely de-energized, open the control room panel 7, mechanism room panel 8, and cable working compartment door 9 for maintenance.

[0043] (2) Power is restored after the maintenance is completed; Close control room panel 7, mechanism room panel 8, cable work compartment door 9 → open grounding switch, close load switch or disconnect switch, close circuit breaker switch → close upper door panel 12 → secure buckle 18 → lock buckle lock 18-3.

[0044] This utility model presents a novel solution with a simple structure. Its solution balances low cost and high reliability, and is flexible and convenient to install.

[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
