[0057] The core of this application is to disclose a power equipment to improve the convenience of on-site maintenance of power equipment.

[0058] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0059] Combination Figures 1-20 The power equipment disclosed in this application includes a cabinet assembly 100 and an air inlet assembly 200. The air inlet assembly 200 includes a mounting assembly 220 and a dustproof assembly 250. The mounting assembly 220 is disposed outside the cabinet assembly 100 and has an air inlet duct 224 communicating with the inner cavity of the cabinet assembly 100. The dustproof assembly 250 is detachably connected to the mounting assembly 220 and is disposed on the air inlet duct 224. The dustproof assembly 250 is used to block and filter sand and dust in the environment to achieve safety protection for the interior of the cabinet assembly 100. The detachable connection between the dustproof assembly 250 and the mounting assembly 220 includes, but is not limited to, screw connection, snap-fit ​​connection, and plug-in connection. For example, this power equipment can specifically be a photovoltaic distribution cabinet.

[0060] Compared to existing technologies, the power equipment disclosed in this application has its air intake component 200 located outside the cabinet component 100, enabling external maintenance and thus avoiding any impact on the internal components of the cabinet component 100 during maintenance. This allows for uninterrupted maintenance of the air intake component 200 without shutting down the machine or interrupting power. In addition, this application detachably mounts the dustproof component 250, which has a high maintenance frequency, onto the mounting component 220, and allows for direct installation and removal from outside the cabinet, greatly improving maintenance efficiency and thus enhancing the convenience of on-site maintenance of the power equipment.

[0061] In a specific embodiment disclosed in this application, the air inlet assembly 200 includes a first mounting body 221 and a second mounting body 222. The first mounting body 221 is disposed outside the cabinet assembly 100 and has an air inlet 211. The dustproof assembly 250 is detachably connected to the first mounting body 221. The second mounting body 222 is disposed outside the cabinet assembly 100 and connected to the cabinet assembly 100. The second mounting body 222 and the first mounting body 221 are connected to form an installation space 223 and have a first air outlet 225. An air inlet duct 224 is disposed in the installation space 223. The air inlet end 224a of the air inlet duct 224 is connected to the air inlet 211, and the air outlet end 224b of the air inlet duct 224 is connected to the inner cavity of the cabinet assembly 100 through the first air outlet 225. During the process of air intake into the cabinet assembly 100 through the air intake duct 224, the airflow in the air intake duct 224 flows from the air intake end 224a to the air outlet end 224b; the first mounting body 221 and the second mounting body 222 are split structures, which can be detachably connected by screws, snaps or other methods, which is convenient for on-site disassembly and maintenance.

[0062] The cooling fan 230 is typically located at the air inlet assembly 200. Specifically, the cooling fan 230 is mounted at the first air outlet 225 within the installation space 223 via a fan mounting plate 231. The fan mounting plate 231 is detachably connected to the second mounting body 222. The separate structure of the first mounting body 221 and the second mounting body 222 facilitates the assembly of the cooling fan 230 within the installation space 223. Furthermore, a mounting protrusion can be provided on the second mounting body 222, and the fan mounting plate 231 is positioned and connected to the mounting protrusion for easy positioning and assembly.

[0063] The number of dustproof components 250 is at least one. When the air inlet assembly 200 includes multiple dustproof components 250, each dustproof component 250 can be arranged sequentially at different positions within the air inlet duct 224 along the airflow direction to achieve multiple filtrations of the airflow and ensure dustproof effect; alternatively, each dustproof component 250 can be installed at different air inlets 211 on the mounting assembly 220 to achieve multi-directional air intake and dust removal. Figure 2 and Figure 8 In some embodiments, the first mounting body 221 and the second mounting body 222 form a rectangular cubic structure. Air inlets 211 can be provided on each of the circumferential side walls of the mounting assembly 220, excluding the top and bottom walls, and a dustproof assembly 250 can be arranged on each of these side walls to achieve air intake and dust removal. For example, air inlets 211 and dustproof assemblies 250 can be provided only on three circumferential side walls of the electrical equipment, forming... Figures 9-11 The technical solution of three-sided air intake is shown in the figure.

[0064] To simplify the assembly and disassembly process and avoid the tediousness of screw removal, in some embodiments, the air intake assembly 200 includes at least one of the aforementioned dustproof assemblies 250, combined with... Figure 8 The first mounting body 221 is provided with a mounting guide rail 212, and at least one dustproof component 250 is slidably mounted on the mounting guide rail 212. The dustproof component 250 can be disassembled and assembled by pulling along the mounting guide rail 212 without removing screws, making maintenance efficient and convenient.

[0065] In other embodiments, the air intake assembly 200 includes at least one of the aforementioned dustproof assemblies 250, combined with Figure 19 A snap-fit ​​component 254 is provided on the dustproof component 250, which snaps into the first mounting body 221. This design is simple and easy to install and remove. The snap-fit ​​component 254 can be, but is not limited to, a spring plunger or a snap-fit ​​protrusion. For example, in conjunction with... Figure 19 One side of the dustproof component 250 is provided with a snap-fit ​​protrusion by welding or other means, which is snap-fitted and fixed to the first mounting body 221. The other side is snap-fitted and fixed to the first mounting body 221 by a spring plunger. On-site maintenance of the dustproof component 250 can meet the requirements of screwless operation, which improves the convenience of maintenance.

[0066] When the air intake assembly 200 includes multiple dustproof assemblies 250 as described above, different dustproof assemblies 250 can be connected to the mounting assembly 220 in different ways. For example, Figure 8 The image shows a three-sided air intake assembly 200, in which two dustproof assemblies 250 are connected to the first mounting body 221 via mounting rails 212 and are disposed within the mounting space 223, while another dustproof assembly 250 is connected to the first mounting body 221 via a snap-fit ​​connector 254 and is disposed outside the mounting space 223.

[0067] The air inlet 211 can be a louvered opening provided on the first mounting body 221, and the dustproof component 250 can be provided inside or outside the mounting space 223.

[0068] In some embodiments disclosed in this application, combined with Figure 18The first mounting body 221 includes a fixing part 2211 and an air inlet screen plate 2212. The fixing part 2211 is connected to the second mounting body 222. The air inlet screen plate 2212 is detachably connected to the fixing part 2211, and an air inlet duct 224 is formed between the air inlet screen plate 2212 and the fixing part 2211. The dustproof component 250 is detachably connected to the fixing part 2211 and is disposed between the air inlet screen plate 2212 and the fixing part 2211. An air inlet 211 is provided on the air inlet screen plate 2212. When disassembling and maintaining the dustproof component 250, the air inlet screen plate 2212 needs to be removed from the fixing part 2211 first, and then the dustproof component 250 can be disassembled and assembled. In this embodiment, the dustproof component 250 is disposed in the installation space 223, which reduces the overall space occupied by the power equipment and improves the space utilization rate.

[0069] To meet dustproof and waterproof requirements, in some embodiments, combined with Figures 12-14 The mounting assembly 220 also includes a dust cover 260, which has an air inlet duct 224. The dust cover 260 is detachably connected to the first mounting body 221 via the dust cover 260 and is disposed within the air inlet duct 224 on the dust cover 260. As the airflow travels along the air inlet duct 224 of the dust cover 260, it is first cleaned by the dust cover 250, then enters the mounting space 223, and finally is driven by the cooling fan 230 to flow into the inner cavity of the cabinet assembly 100. Figure 12 In specific usage scenarios, the dust cover 260's opening faces downwards, effectively preventing horizontal rainwater and dust from directly entering the cabinet assembly 100. When disassembling and maintaining the dust cover assembly 250, the dust cover 260 must first be removed from the first mounting body 221, and then the dust cover assembly 250 must be removed from inside the dust cover 260. The dust cover assembly 250 and dust cover 260 can also be installed and fixed using detachable structures such as clips or spring plungers to meet the need for quick disassembly.

[0070] To further optimize the design, the mounting component 220 also includes a partition component 240. The partition component 240 is disposed within the mounting space 223 and divides the mounting space 223 into curved or other shaped air intake ducts 224. This allows the airflow within the air intake ducts 224 to fully contact the partition component 240, thereby enabling the partition component 240 to block water droplets flowing towards the cooling fan 230 and the cabinet component 100 to a certain extent, thus meeting the dustproof and waterproof requirements of P54 or other levels. For example, the mounting space 223 can be divided into an overall S-shaped air intake duct 224 by the positional arrangement of the partition component 240, or the air intake duct 224 can be formed by the positional arrangement of the partition component 240 to form an air intake duct 224 with a cross-sectional area that gradually increases or decreases from the air intake end 224a to the air outlet end 224b.

[0071] In some embodiments, the partition assembly 240 includes a first partition 241 and a second partition 242. The first partition 241 is disposed on the side of the first mounting body 221 facing the second mounting body 222, and the second partition 242 is disposed on the side of the second mounting body 222 facing the first mounting body 221. A first gap 243 is formed between the first partition 241 and the second mounting body 222, and a second gap 244 is formed between the second partition 242 and the first mounting body 221. Along the direction from the air inlet 211 to the first air outlet 225, the first gap 243 and the second gap 244 are staggered to form an S-shaped air inlet duct 224. The partition assembly 240 includes at least one set of first partitions 241 and at least one set of second partitions 242. When the partition assembly 240 includes multiple sets of first partitions 241 and multiple sets of second partitions 242, the sets of first partitions 241 and the sets of second partitions 242 are arranged alternately. For example, in combination with... Figure 8 , Figure 8 The diagram illustrates a three-sided air intake assembly 200, and a partition assembly 240 comprising two sets of first partitions 241 and one set of second partitions 242. Each set of first partitions 241 includes three first partitions 241, which correspond to three dustproof components 250 and are arranged in a U-shape. Each set of second partitions 242 includes three second partitions 242, which correspond to three dustproof components 250 and are arranged in a U-shape. Each second partition 242 is positioned between two first partitions 241 to form a curved air intake duct 224. Airflow from all directions can flow along the air intake duct 224 formed by the partition assembly 240. During the airflow into the cabinet assembly 100, each first partition 241 and second partition 242 can repeatedly block water droplets and dust in the air, thereby improving the dustproof and waterproof effect.

[0072] In other embodiments, combined with Figure 16 The first partition 241 includes a main water-blocking partition 2411 and a side water-blocking partition 2412. The two side water-blocking partitions 2412 are located on both sides of the main water-blocking partition 2411 and are arranged at right angles or other included angles with the main water-blocking partition 2411. The main water-blocking partition 2411 is connected to the second partition 242 and together they block water. At the same time, the main water-blocking partition 2411 directs the airflow to the two side water-blocking partitions 2412. The side water-blocking partitions 2412 and the first mounting body 221 have the aforementioned second gap 244, which allows airflow to pass through, thereby forming a curved air inlet duct 224 to ensure the waterproof and dustproof effect of the partition assembly 240.

[0073] To facilitate the disassembly and maintenance of the cooling fan 230, the cooling fan 230 can be slidably mounted on the second mounting body 222 via a pull-out guide rail. The partition assembly 240 arranged between the cooling fan 230 and the dustproof component 250 and / or the air inlet screen plate 2212 is set as a detachable structure. Thus, when the cooling fan 230 needs maintenance, the dustproof component 250 and / or the air inlet screen plate 2212 can be removed, and then the aforementioned detachable partition assembly 240 can be removed. The cooling fan 230 can then be pulled out from the mounting space 223 for maintenance.

[0074] Combination Figure 20 The dustproof component 250 includes a dustproof cotton 253, a dustproof support plate 251, and a dustproof pressure plate 252. The dustproof support plate 251 and the dustproof pressure plate 252 are detachably connected, and the dustproof cotton 253 is disposed between the dustproof support plate 251 and the dustproof pressure plate 252. The dustproof support plate 251 is detachably connected to the mounting component 220 via fittings 255 such as spring plungers and snap-fit ​​protrusions, facilitating the disassembly and replacement of the dustproof cotton 253. The fittings 255 can be installed on the dustproof support plate 251 by welding, screwing, snap-fitting, etc., resulting in a simple structure and convenient production. The fittings 255 and the aforementioned snap-fitting parts 254 can be of the same structure, meaning that the fittings 255 simultaneously connect the dustproof support plate 251 and the dustproof pressure plate 252, as well as connect the dustproof support plate 251 and the mounting component 220, thereby simplifying the structure and reducing costs.

[0075] Combination Figure 4 The cabinet assembly 100 includes a cabinet body 110, a cabinet door assembly 120, and a side door assembly 130. The cabinet door assembly 120 is hinged or similarly mounted on the cabinet body 110, and the side door assembly 130 is also hinged or similarly mounted on the cabinet body 110. The cabinet door assembly 120 and the side door assembly 130 are located on different sides of the cabinet body 110. For ease of maintenance and management, the communication and power distribution components inside the cabinet body 110 are modularly installed, resulting in a compact structure. This allows for quick and easy replacement of any components in case of failure, simplifying maintenance and improving the on-site maintenance experience and product quality. Specifically, a first power distribution device 400 and a second power distribution device 410 are provided inside the cabinet body 110. The first power distribution device 400 is located at the cabinet door assembly 120 and is arranged opposite to the cabinet door assembly 120. The second power distribution device 410 is located at the side door assembly 130 and is arranged opposite to the side door assembly 130, so as to facilitate the disassembly and maintenance of the first power distribution device 400 and the second power distribution device 410 from the cabinet door assembly 120 and the side door assembly 130, respectively.

[0076] Combination Figure 2The side door assembly 130 includes a side door panel 132, a first hinge 131, and a door lock 133. A device maintenance window is provided on the upper half of the side of the cabinet body 110, and the device maintenance window can be closed by the side door assembly 130. The cabinet door assembly 120 has a similar structure to the side door assembly 130, and will not be described in detail here.

[0077] For example, the first power distribution device 400 may include a terminal component and a PCB (Printed Circuit Board) mounting plate, and the second power distribution device 410 may include an uninterruptible power supply (UPS) component. The terminal component is located on one side of the PCB mounting plate and is used to mount a visualization terminal 404 such as a meter and a display. Specifically, in conjunction with... Figure 3 The terminal assembly includes a terminal mounting plate 401, a second hinge 402, a fixed bracket 403, and a visualization terminal 404. The fixed bracket 403 is fixed to the cabinet body 110. The terminal mounting plate 401 is hinged to the fixed bracket 403 via the second hinge 402.

[0078] In some embodiments disclosed in this application, the cabinet body 110 is provided with a support beam 411, a mounting tray 413, a first limiting member 412, and a second limiting member 416. The support beam 411 extends toward the side door assembly 130. The mounting tray 413 is slidably mounted on the support beam 411 and can slide along the support beam 411 to the side door assembly 130. A limiting plate 415 is provided at the first end 413a of the mounting tray 413. A second power distribution device 410 is mounted on the mounting tray 413. The first limiting member 412 is mounted on the support beam 411 or the cabinet body 110 and is used to interact with the mounting tray 413. The second end 413b abuts against the first end 413a to restrict the placement of the mounting tray 413 within the cabinet body 110. The first end 413a and the second end 413b are the two ends of the mounting tray 413 along the sliding direction, with the first end 413a closer to the side door assembly 130 than the second end 413b. The second limiting member 416 is disposed on the support beam 411 or the cabinet body 110 and is detachably connected to the limiting plate 415. This detachable connection between the second limiting member 416 and the limiting plate 415 fixes the position of the mounting tray 413 within the cabinet body 110 without affecting the disassembly and maintenance of the mounting tray 413. The second power distribution device 410 can be quickly moved and disassembled by dragging the mounting tray 413 along the support beam 411.

[0079] To facilitate operation by workers, combined with Figure 5A handle 414 is provided on the mounting tray 413. The second power distribution device 410 can be detachably fixed to the mounting tray 413 by means of straps, screws, etc. When the second power distribution device 410 malfunctions on site and needs to be repaired or replaced, the side door assembly 130 can be opened to release the detachable connection between the second limiting member 416 and the limiting plate 415 by screws, snaps, etc., disconnect the connecting cable of the second power distribution device 410, and finally pull out the second power distribution device 410 and the mounting tray 413 as a whole for maintenance using the handle 414.

[0080] Further optimize the plan, combined with Figure 6 In some embodiments, the first limiting member 412 is provided with a first positioning slope 4121, and the mounting tray 413 is provided with a second positioning slope 4131 that fits against the first positioning slope 4121. During the process of the mounting tray 413 sliding towards the first limiting member 412, the first positioning slope 4121 and the second positioning slope 4131 gradually fit together and lock together, thereby realizing the position limitation of the mounting tray 413. The cooperation structure of the first positioning slope 4121 and the second positioning slope 4131 can realize the positioning and fixing function without affecting the operator's pulling and moving of the mounting tray 413.

[0081] Combination Figure 4 The electrical equipment also includes an air outlet assembly 300. A heat dissipation duct is formed within the cabinet assembly 100, extending from the air inlet assembly 200 to the air outlet assembly 300. Airflow enters the cabinet assembly 100 through the air inlet duct 224 and flows along the duct, carrying away heat from the internal components of the cabinet body 110, before finally exiting through the air outlet assembly 300. The air outlet assembly 300 includes an air outlet base plate 310 and an air outlet mesh plate 320. The air outlet base plate 310 is connected to the cabinet assembly 100, and a second air outlet 311 is provided on the base plate 310. The second air outlet 311 communicates with the inner cavity of the cabinet assembly 100 and is used for air outlet. The air outlet mesh plate 320 is detachably mounted at the second air outlet 311 for easy disassembly and maintenance. The air outlet mesh plate 320 prevents impurities and insects from the external environment from entering the cabinet assembly 100.

[0082] Specifically, a wire mesh guide rail 321 can be installed on the air outlet base plate 310. The air outlet base plate 310 is slidably installed at the second air outlet 311 via the wire mesh guide rail 321. The air outlet wire mesh plate 320 can be removed by pulling it out for cleaning.
