Description

Technical Field

[0001] This invention relates to the field of power distribution cabinets, and more particularly to an outdoor floor-standing power distribution box. Background Technology

[0002] Currently, during the installation and construction of conventional outdoor floor-mounted distribution cabinets, it is common practice to first pour a cement base on site, and then use pre-embedded structures to bolt the entire distribution cabinet to the top surface of the cement base to achieve stable installation of the equipment. This ensures the stability of the distribution cabinet installation and its outdoor wind resistance and load-bearing performance, meeting the basic installation requirements for long-term outdoor operation.

[0003] However, outdoor distribution boxes are exposed to the natural environment for extended periods, constantly subjected to the effects of sunlight, rain, wind, and sand erosion. Metal cabinets are highly susceptible to rust, deformation, paint peeling, aging, and other damage. Existing outdoor floor-mounted distribution cabinets often employ an integrated cabinet design, where all electrical components, control modules, wiring assemblies, and other core power distribution structures are integrated and fixed within a closed cabinet. When the cabinet is damaged, the entire distribution cabinet must be disassembled, power disconnected, and the entire device replaced, followed by rewiring, debugging, and reinstallation. This process consumes significant manpower, resources, and time, substantially increasing equipment maintenance costs. Furthermore, the complete disassembly and reassembly operation results in prolonged power outages for the outdoor distribution system, severely impacting the continuity and stability of regional power supply and hindering the routine and efficient maintenance of outdoor power distribution equipment. Summary of the Invention

[0004] To overcome the shortcomings of existing outdoor floor-standing power distribution cabinets, which mostly adopt an integrated cabinet structure design, requiring the entire power distribution cabinet to be disassembled when the cabinet is damaged, which consumes a lot of manpower, material resources and time costs and significantly increases equipment operation and maintenance costs, this invention provides an outdoor floor-standing power distribution box.

[0005] The technical solution is as follows: An outdoor floor-mounted distribution box includes a cement base; the cement base is made of reinforced concrete; it also includes a base plate connected to the cement base, the base plate is made of steel plate, and several conduits are installed on the base plate; several connecting seats are fixedly connected to the base plate; all connecting seats are detachably connected to a mounting frame; several DIN rails are adjustablely connected to the mounting frame; a cabinet is installed on the mounting frame, the cabinet is a frame structure without a top and bottom surface, and a temperature sensor is installed inside the cabinet; an internal support assembly for installing the cabinet is connected to the mounting frame; several air intake slots are opened on the lower side of the cabinet; a rain cover is installed on the cabinet; several cooling fans are installed on the upper and lower sides of the mounting frame; an internal support assembly for moving the cabinet and rain cover up and down is connected to the mounting frame; several rain sensors are installed on the rain cover.

[0006] As a further preferred option, the internal support assembly includes several slide rails connected to the mounting bracket; several internal support blocks are slidably connected to each slide rail; several locking screws are threaded onto each internal support block; and each locking screw passes through the side wall of the cabinet and is tightened onto the corresponding internal support block.

[0007] As a further preferred embodiment, the drive assembly includes several limiting plates connected to the cabinet; a first electric push rod is fixedly connected to the upper side of each limiting plate; the telescopic end of each first electric push rod is fixedly connected to the rain cover; several second electric push rods are fixedly connected to the lower side of the mounting bracket; the telescopic end of each second electric push rod is fixedly connected to the corresponding inner support block.

[0008] As a further preferred option, protective doors are installed on both the front and rear sides of the cabinet; DIN rails can be installed on both the front and rear sides of the mounting bracket.

[0009] As a further preferred option, the inner support block is C-shaped, so that it comes into contact with the protective doors on the front and back sides of the cabinet.

[0010] By adopting the above structure, the C-shaped inner support block can provide multi-directional support and protection for the cabinet from the inside, significantly improving the cabinet's wind resistance, rain protection, and collision resistance.

[0011] As a further preferred option, a washer is also included; the locking screw is equipped with a washer made of rubber.

[0012] By adopting the above structure, the present invention can prevent the locking screws from loosening due to external vibration, and at the same time effectively prevent rainwater from seeping into the cabinet through the screw installation gaps.

[0013] As a further preferred option, it also includes a detachable sealing plate connected to the bottom of the cabinet; the lower surface of the sealing plate is provided with a rubber layer, and the lower surface of the sealing plate is in contact with and adheres to the upper surface of the cement base.

[0014] As a further preferred option, it also includes a sealing ring connected to the cabinet; the sealing ring is fixed to the upper side of the cabinet and is made of rubber; the sealing ring is in contact with and fits the rain cover.

[0015] As a further preferred option, a filter is also included; a filter is fixed to each air intake slot.

[0016] By adopting the above structure, this invention can filter the air entering the cabinet through the air inlet slot, intercepting dust, lint, debris and other contaminants in the air, preventing pollutants from entering the cabinet and adhering to the surface of electrical components, and ensuring the clean operation of the equipment.

[0017] As a further preferred option, it also includes photovoltaic panels connected to the rain cover; the rain cover is equipped with photovoltaic panels.

[0018] The beneficial effects are as follows: electrical components are directly mounted on the mounting frame above the cement base, and the cabinet is independently fitted onto the outside of the mounting frame via internal support components; when the cabinet is damaged, the operator only needs to remove all the locking screws, release the locking relationship between the internal support block and the cabinet, lift the cabinet upwards and remove it from the mounting frame, and replace it with a brand new cabinet to complete the maintenance work, without having to disassemble and replace the entire distribution cabinet, effectively reducing manpower, material resources and time costs, and reducing equipment operation and maintenance expenses; at the same time, disassembling and assembling the cabinet alone will not interrupt the power supply of the power distribution system, ensuring continuous and stable power supply in the area; in addition, the C-shaped internal support block can provide multi-directional support and protection for the cabinet from the inside, significantly improving the cabinet's wind resistance, rain protection and impact resistance;

[0019] In the initial state, the first electric push rod is fully retracted, and the rain cover is attached to the top of the cabinet; the second electric push rod is also in the retracted state, with the inner wall of the cabinet attached to the upper surface of the cement base. The air intake slot is blocked and sealed by the cement base, which can effectively prevent external moisture, dust and other impurities from entering the cabinet. In the high-temperature room in summer, the drive component moves the cabinet and rain cover upward, so that the top and bottom sides of the cabinet are connected to the outside. Then the cooling fan is activated to form a circulating airflow inside the cabinet, which greatly improves the overall heat dissipation effect of the solid. Attached Figure Description

[0027] Example 1: An outdoor floor-mounted distribution box, such as Figures 1-5 As shown, it includes a cement base 1; the cement base 1 is made of reinforced concrete.

[0028] It also includes a base plate 101, a mounting bracket 102, a cabinet 103, a rain cover 106, a cooling fan 107, a rain sensor 207, an internal support assembly, and a drive assembly; the base plate 101, which is made of steel plate, is pre-embedded and installed on the cement base 1, and several conduits 1001 are installed on the base plate 101; two connecting seats 10101 are welded on the base plate 101; all connecting seats 10101 are bolted to the mounting bracket 102; several DIN rails 10201 are adjustablely connected to the mounting bracket 102; the cabinet 103 is installed on the mounting bracket 102, and the cabinet 103 is... The cabinet has a frame structure without a top and bottom surface, and a temperature sensor is installed inside the cabinet 103. An internal support assembly is connected to the mounting bracket 102, through which the cabinet 103 is fitted onto the mounting bracket 102. Several air inlets 10302 are opened on the lower side of the cabinet 103. A rain cover 106 is installed on the cabinet 103. Two cooling fans 107 are installed on the upper and lower sides of the mounting bracket 102. The internal support assembly is connected to the mounting bracket 102, through which the cabinet 103 and the rain cover 106 are moved up and down. Two rain sensors 207 are installed on the rain cover 106.

[0029] The internal support assembly includes a slide rail 202, an internal support block 203, and locking screws 204; two left-right symmetrical slide rails 202 are welded onto the mounting bracket 102; several internal support blocks 203 are slidably connected to each slide rail 202; two locking screws 204 are threadedly connected to each internal support block 203; each locking screw 204 passes through the side wall of the cabinet 103 and is tightened onto the corresponding internal support block 203.

[0030] The drive assembly includes a limit plate 104, a first electric push rod 105, and a second electric push rod 206. Two limit plates 104 are fixedly connected to the upper side of the cabinet 103. A first electric push rod 105 is fixedly connected to the upper side of each limit plate 104. The telescopic end of each first electric push rod 105 is fixedly connected to the rain cover 106. In the initial state, the first electric push rod 105 is in the retracted state, and the rain cover 106 is in contact with the upper end of the cabinet 103. Two second electric push rods 206 are fixedly connected to the lower side of the mounting bracket 102. The telescopic end of each second electric push rod 206 is fixedly connected to the corresponding inner support block 203. In the initial state, the telescopic end of the second electric push rod 206 is in the retracted state, and the inner wall of the cabinet 103 is in contact with the upper outer wall of the cement base 1. The air inlet slot 10302 is located on the upper outer wall of the cement base 1, and the air inlet slot 10302 is in a sealed state.

[0031] The cabinet 103 is equipped with protective doors 10301 on both the front and rear sides; the mounting bracket 102 can be equipped with DIN rails 10201 on both the front and rear sides.

[0032] The inner support block 203 is C-shaped, so that the inner support block 203 will come into contact with the protective doors 10301 on the front and rear sides of the cabinet 103.

[0033] Example 1 Working Principle: During construction, the base plate 101 is first placed in the preset position, and the underground connecting wires are pre-threaded into the conduit 1001; then, the formwork is erected and the cement base 1 is poured. During the pouring process, the base plate 101 is simultaneously embedded and fixed in the cement base 1 to ensure accurate positioning and dense pouring; after the base is formed, the base plate 101 is reliably grounded. After all basic procedures are accepted, the subsequent installation work of the distribution cabinet can be carried out; when installing the distribution cabinet, the mounting bracket 102 is first placed on the installation point of the connecting seat 10101, and then the mounting bracket 102 and the connecting seat 10101 are locked and fixed with bolts to complete the assembly of the mounting bracket 102 and the base plate 101; then, the electrical components are installed on the DIN rail 10201. The position of the DIN rail 10201 can be adjusted up and down according to the operation requirements to facilitate the overall assembly of components. After the electrical components are installed, the connecting cables led out from the conduit 1001 are connected to the corresponding electrical components. Then, the worker puts the cabinet 103 down onto the mounting frame 102 from the top. When the cabinet 103 is completely covered by the outside of the mounting frame 102, the limiting plate 104 will contact the upper surface of the mounting frame 102. At this time, the limiting plate 104 provides temporary support for the cabinet 103 to facilitate subsequent installation operations. Then, the worker moves the inner support block 203 to the corresponding position and tightens the locking screw 204 through the cabinet 103 onto the corresponding inner support block 203, thereby fixing the cabinet 103 and the inner support block 203 together.

[0034] This structure directly mounts electrical components onto the mounting bracket 102 above the cement base 1, while the cabinet 103 is independently fitted onto the outside of the mounting bracket 102 via an internal support assembly. When the cabinet 103 is damaged, operators only need to remove all the locking screws 204, release the locking relationship between the internal support block 203 and the cabinet 103, lift the cabinet 103 upwards and remove it from the mounting bracket 102, and replace it with a brand new cabinet 103 to complete the maintenance work. There is no need to disassemble and replace the entire distribution cabinet, effectively reducing manpower, material resources, and time costs, and reducing equipment operation and maintenance expenses. At the same time, disassembling and assembling the cabinet 103 alone will not interrupt the power supply of the power distribution system, ensuring continuous and stable power supply in the area. In addition, the C-shaped internal support block 203 can provide multi-directional support and protection for the cabinet 103 from the inside, significantly improving the cabinet 103's wind resistance, rain protection, and impact resistance.

[0035] Furthermore, DIN rails 10201 can be installed on both the front and rear sides of the mounting bracket 102, allowing electrical components to be arranged on both sides of the mounting bracket 102 simultaneously, effectively improving space utilization. Protective doors 10301 are installed on both the front and rear sides of the cabinet 103. During routine inspection and maintenance, only the protective door 10301 on the corresponding side needs to be opened to perform maintenance operations on the electrical components on the front and rear sides of the mounting bracket 102.

[0036] After the cabinet 103 is installed, in the initial state, the first electric push rod 105 is fully retracted, and the rain cover 106 is attached to the top of the cabinet 103; the second electric push rod 206 also remains retracted, the inner wall of the cabinet 103 is attached to the upper surface of the cement base 1, and the air inlet slot 10302 is blocked and sealed by the cement base 1, which can effectively prevent external moisture, dust and other impurities from entering the cabinet 103; when operating in a high-temperature environment in summer, the first electric push rod 105 is controlled to extend upward, driving the rain cover 106 to rise, so that the rain cover 106 separates from the top of the cabinet 103, forming a heat dissipation channel connecting the two to the outside; then the second electric push rod 206 is controlled to extend upward, driving the inner support block 203 to move upward along the slide rail 202, and so on. The first step lifts the cabinet 103 and its accessories, moving the air intake slot 10302 above the cement base 1. Then, all the cooling fans 107 are activated. The lower cooling fan 107 draws cold air from the outside into the cabinet 103, while the upper cooling fan 107 exhausts the hot air inside the cabinet 103 through the heat dissipation channel between the rain cover 106 and the cabinet 103, forming a circulating airflow inside the cabinet 103 and greatly improving the overall heat dissipation effect. When the rain sensor 207 detects a rainfall signal, the second electric push rod 206 drives the cabinet 103 to move downwards and reset, and the first electric push rod 105 drives the rain cover 106 to fall back and reset, so that the cabinet 103 returns to a closed state to prevent rainwater from entering the cabinet 103.

[0037] It also includes a washer 205; the locking screw 204 is provided with a washer 205, which is made of rubber.

[0038] The rubber gasket 205 increases the contact friction between the locking screw 204 and the side wall of the cabinet 103, preventing the locking screw 204 from loosening due to external vibrations. At the same time, it can also buffer and dampen shocks, and seal and waterproof, effectively preventing rainwater from seeping into the cabinet 103 through the screw installation gaps, further improving the overall structural stability and outdoor protection performance.

[0039] It also includes a sealing plate 108; the lower side of the cabinet 103 is bolted to it; the lower surface of the sealing plate 108 is provided with a rubber layer, and the lower surface of the sealing plate 108 is in contact with and adheres to the upper surface of the cement base 1.

[0040] The rubber layer can fill the gap between the sealing plate 108 and the cement base 1, playing a role in sealing, dustproofing, waterproofing and moisture-proofing, effectively preventing water vapor and debris from entering the internal electrical area from the bottom gap of the cabinet 103; at the same time, it can buffer the hard contact between the cabinet 103 and the cement base 1, reduce vibration transmission, improve structural stability, and the sealing plate 108 is connected by bolts for easy maintenance and replacement in the future.

[0041] It also includes a sealing ring 109; the sealing ring 109 is fixedly attached to the upper side of the cabinet 103, and the sealing ring 109 is made of rubber; the sealing ring 109 is in contact and fits with the rain cover 106.

[0042] The rubber sealing ring 109 can fill the assembly gap between the cabinet 103 and the rain cover 106, providing waterproofing, dustproofing, and shock absorption. This effectively enhances the sealing and protection capabilities of the top of the cabinet 103, preventing rainwater and impurities from entering the equipment through the joint.

[0043] Example 2: Based on Example 1, Figure 1 and Figure 2 As shown, it also includes a filter screen 201; a filter screen 201 is fixedly attached to each air inlet slot 10302.

[0044] It also includes a photovoltaic panel 208; the photovoltaic panel 208 is installed on the rain cover 106.

[0045] Working principle of Example 2: The filter 201 can filter the air entering the cabinet 103 through the air inlet slot 10302, intercepting dust, lint, debris and other impurities in the air, preventing pollutants from entering the cabinet and adhering to the surface of electrical components, and ensuring the clean operation of the equipment; the photovoltaic panel 208 can use outdoor sunlight to generate photovoltaic power, supplementing the power supply for electrical components such as the cooling fan 107, various sensors, and electric push rods, reducing the energy consumption of the external mains power and realizing the efficient use of energy.
