Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to assembly racks, outdoor battery cabinets, and three-phase power supply outdoor cabinets. Background Technology

[0002] An intelligent AC-DC-AC purification power supply is a type of power device used to improve power quality, providing a stable and clean power supply for various precision equipment and critical loads. Its working principle involves first converting the input AC power into DC power through a rectifier circuit. Utilizing the unidirectional conductivity of power electronic devices such as diodes or thyristors, the positive and negative half-cycles of the AC power are converted into positive and negative DC voltages, respectively, resulting in a DC voltage output with a certain amount of ripple—this is AC-DC conversion. The rectified DC power typically contains a significant ripple component, requiring smoothing through a filter circuit. This filter circuit generally consists of energy storage components such as capacitors and inductors. Capacitors store charge, charging when the voltage rises and discharging when the voltage falls, thus reducing voltage fluctuations. Inductors impede changes in current, suppressing sudden current changes and further reducing the ripple coefficient, making the output DC voltage more stable and smooth—this is DC filtering.

[0003] The filtered DC power is converted back to AC power by an inverter circuit. The inverter circuit uses fully controlled power electronic devices, such as insulated gate bipolar transistors (IGBTs), to convert DC voltage into AC power with adjustable frequency and amplitude according to a certain control strategy. During the inversion process, by controlling the on and off times of the IGBTs, the waveform, frequency, and amplitude of the output AC power can be precisely controlled to meet the requirements of the load, which is called DC-AC inversion.

[0004] To further improve the quality of the output AC power and reduce harmonic content and electromagnetic interference, an output filter circuit is usually connected to the output of the inverter. These filters can filter out specific harmonic frequencies, making the output AC power closer to a sine wave. They can also reduce electromagnetic radiation and reduce interference to surrounding equipment. Furthermore, they may be equipped with electromagnetic shielding, common-mode rejection and other technologies to further enhance their purification capabilities and provide a clean power supply to the load. This is the process of output filtering and purification.

[0005] In certain application scenarios, intelligent AC / DC / AC purification power supplies are used in conjunction with batteries. When used outdoors, batteries need to be centrally stored in outdoor battery cabinets. Generally, outdoor battery cabinets have multi-layered structures to store several batteries in an orderly manner. However, outdoor conditions are complex, and outdoor battery cabinets are prone to shaking, which can cause collisions between the batteries and the cabinet. The batteries are relatively heavy, and over time, this can easily damage the outdoor battery cabinet and reduce its lifespan. Utility Model Content

[0057] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0058] This application provides a three-phase power supply outdoor cabinet, which includes an outdoor battery cabinet and an outdoor power supply cabinet. The outdoor battery cabinet is configured to install a battery assembly, which includes a plurality of target batteries 3000. The outdoor power supply cabinet is configured to install a power system, which is connected to the battery assembly.

[0059] Regarding the aforementioned outdoor battery cabinets, please refer to... Figures 1 to 15 As shown, the outdoor battery cabinet may include a base cabinet 1000 and an assembly platform 2000. The base cabinet 1000 has an internal cavity, and the assembly platforms 2000 are disposed within the internal cavity of the base cabinet 1000. Several assembly platforms 2000 are configured, and these platforms are assembled into the internal cavity along the height direction of the base cabinet 1000. Adjacent assembly platforms 2000 in the height direction have a platform spacing height, which can be limited to be greater than 1.5 times the height of the target battery 3000. This provides a larger spacing space between adjacent layers of assembly platforms 2000 in the height direction, allowing for better heat dissipation of the target battery 3000.

[0060] Regarding the aforementioned assembly platform 2000, the assembly platform 2000 may include a platform base plate 2100, a connecting plate assembly, and a limiting plate assembly. The platform base plate 2100, the connecting plate assembly, and the limiting plate assembly of the assembly platform 2000 may adopt an integral molding structure, and then the connecting plate assembly and the limiting plate assembly are formed by partially bending the platform base plate 2100. The assembly platform 2000 may be made of metal plate or plastic plate with deformation function, such as aluminum plate, etc. In addition, it may also be made of steel plate, stainless steel plate, etc., without limitation.

[0061] The mounting base 2100 includes two first plate sides facing opposite directions and two second plate sides facing opposite directions. The two first plate sides and the two second plate sides are arranged sequentially at intervals along the circumference of the mounting base 2100. The two ends of adjacent first plate sides and second plate sides are connected. The two first plate sides and the two second plate sides together constitute the annular circumferential plate side of the mounting base 2100.

[0062] For example, the mounting base 2100 is a rectangular plate with two long sides and two short sides, which can serve as two first plate sides and two second plate sides, respectively. Alternatively, the mounting base 2100 is a square plate with four sides, two pairs of which are opposite each other. In this case, the opposite sides can serve as two first plate sides and two second plate sides, respectively. In addition, those skilled in the art can choose other plate shapes, which are not limited here.

[0063] The connecting plate assembly includes two connecting strips 2200, which are also rectangular plates. Each connecting strip 2200 has a first strip length, which is equal to the side length of the first plate side of the support substrate 2100. The two connecting strips 2200 are respectively connected to the two first plate sides of the support substrate 2100, that is, the long sides of the two connecting strips 2200 are respectively connected to the two first plate sides of the support substrate 2100. Since the first strip length of the connecting strip 2200 is equal to the side length of the first plate side of the support substrate 2100, the two ends of the two connecting strips 2200 in the length direction can contact the two second plate sides of the support substrate 2100, which is equivalent to the length reaching the position of the two second plate sides.

[0064] The limiting plate assembly includes two limiting strips 2300, which are also rectangular plates. Each limiting strip 2300 has a second strip length, which is less than the side length of the second plate side of the support base plate 2100. The two limiting strips 2300 are respectively connected to the two second plate sides of the support base plate 2100, that is, the long sides of the two limiting strips 2300 are respectively connected to the two second plate sides of the support base plate 2100. Since the second strip length of the limiting strip 2300 is less than the side length of the second plate side of the support base plate 2100, at least one end of the two limiting strips 2300 in the length direction is configured to create a buffer gap 2400 with at least one connecting strip 2200 of the connecting plate assembly. In one embodiment, the two connecting strips 2200 of the connecting plate assembly are parallel to each other, and the two limiting strips 2300 are located between the two connecting strips 2200. A buffer gap 2400 is provided between the two ends of the two limiting strips 2300 in the length direction and the inner side surface of the two connecting strips 2200.

[0065] Since the connecting strips 2200 and the limiting strips 2300 can form a buffer gap 2400 during assembly on the mounting base 2100, a buffer allowance can be formed between the connecting strips 2200 and the limiting strips 2300. Moreover, the buffer gap 2400 is formed between the inner side surface of the connecting strip 2200 and the end of the limiting strip 2300. After the connecting strip 2200 is directly or indirectly assembled into the cabinet cavity of the base cabinet 1000 of the outdoor battery cabinet, the stress points of the entire assembly platform 2000 and the base cabinet 1000 of the outdoor battery cabinet are also concentrated on the connecting strip 2200.

[0066] When the outdoor battery cabinet occasionally shakes, the shaking will be transmitted to the connecting strip 2200 of the assembly platform 2000. There is a buffer gap 2400 between the end of the connecting strip 2200 and the adjacent limiting strip 2300. Therefore, the impact on the assembly platform 2000 can be relieved by the buffer gap 2400, and the outdoor battery cabinet will be prevented from being damaged by hard collision.

[0067] Simultaneously, the buffer gap 2400 mitigates the impact on the assembly platform 2000, thereby reducing the shaking of the target batteries 3000 on the assembly platform 2000 and ensuring the safety and stability of the assembly of the target batteries 3000 on the assembly platform 2000. With more stable assembly of the target batteries 3000, they will not impact the outdoor battery cabinet in the opposite direction, thus preventing damage to the outdoor battery cabinet and extending its service life.

[0068] In one embodiment, the connecting strip 2200 has a first strip width, and the limiting strip 2300 has a second strip width. Both the connecting strip 2200 and the limiting strip 2300 are vertically mounted on the support base plate 2100. The first strip width of the connecting strip 2200 and the second strip width of the limiting strip 2300 are both in the thickness direction of the support base plate 2100, wherein the first strip width of the connecting strip 2200 is greater than the second strip width of the limiting strip 2300. Therefore, the downward-facing long side of the connecting strip 2200 is lower than the downward-facing long side of the limiting strip 2300. When the end of the connecting strip 2200 toward the limiting strip 2300 deforms or moves, the connecting strip 2200 can not only reduce the buffer gap 2400, but also deform below the limiting strip 2300, thereby further buffering based on the bending of the connecting strip 2200 in extreme cases.

[0069] In one embodiment, the assembly platform 2000 includes a sliding assembly, which includes at least one sliding rod 2210. The sliding rod 2210 is configured to be assembled into the inner cavity of the base cabinet 1000 of the outdoor battery cabinet. The connecting strip 2200 has at least one limiting sliding hole 2211, and the limiting sliding holes 2211 of the two connecting strips 2200 are configured to be movably sleeved on the sliding rod 2210. The sliding rod 2210 is perpendicular to the two connecting strips 2200.

[0070] When the outdoor battery cabinet occasionally shakes, the shaking is transmitted to the connecting strip 2200 of the assembly platform 2000. A buffer gap 2400 exists between the ends of the connecting strip 2200 and the adjacent limiting strip 2300. Therefore, the buffer gap 2400 can mitigate the impact on the assembly platform 2000, preventing damage to the outdoor battery cabinet from hard collisions. During the deformation or movement of the connecting strip 2200 relative to the outdoor battery cabinet, the connecting strip 2200 can move along the sliding rod 2210 based on the sliding engagement of the limiting sliding hole 2211 and the sliding rod 2210. Therefore, it can maintain a stable assembly state relative to the outdoor battery cabinet during deformation or movement.

[0071] In one embodiment, the assembly platform 2000 further includes a mounting assembly comprising two mounting horizontal plates 2220, a connecting strip 2200 having a plurality of mounting through holes 2221 along its length, and a plurality of mounting buckles provided on the mounting horizontal plates 2220. Each mounting horizontal plate 2220 has a plurality of mounting buckles that are mutually mounted to a matching plurality of mounting through holes 2221 on a connecting strip 2200. The mounting horizontal plates 2220 are configured for assembly into the inner cavity of the base cabinet 1000 of the outdoor battery cabinet. Therefore, each assembly platform 2000 can be assembled into the inner cavity of the base cabinet 1000 of the outdoor battery cabinet based on the two mounting horizontal plates 2220.

[0072] In one embodiment, the front side of the mounting base 2100 has several positioning grooves, for example, such as Figure 8 and Figure 12 As shown, several positioning grooves are distributed along the transverse and longitudinal directions, respectively. Figure 13 As shown, there are groove partition lines between adjacent positioning grooves, and at least one reinforcing crossbar 2110 is provided on the back side of the mounting base 2100. Each reinforcing crossbar 2110 is parallel and corresponds to at least a portion of a groove partition line. Therefore, the strength of the mounting base 2100 can be improved by positioning several reinforcing crossbars 2110 at the groove partition lines between adjacent positioning grooves.

The cabinet panel assembly includes a first cabinet panel 1200 and a second cabinet panel 1300, which are vertically mounted on the cabinet base 1100 and are arranged opposite to each other. The first cabinet panel 1200 and the second cabinet panel 1300 each have a first side and a second side facing opposite directions. The cabinet door assembly includes a first cabinet door 1400 and a second cabinet door 1500. The first cabinet door 1400 is connected to the first side of the first cabinet panel 1200 and the second cabinet panel 1300, and the second cabinet door 1500 is connected to the second side of the first cabinet panel 1200 and the second cabinet panel 1300. The first cabinet door 1400 can be used as a front door, and the second cabinet door 1500 can be used as a rear door.

[0074] The cabinet top cover 1600 is assembled on top of the cabinet panel assembly and the cabinet door assembly. The first cabinet panel 1200 and the second cabinet panel 1300 of the cabinet panel assembly, and the first cabinet door 1400 and the second cabinet door 1500 of the cabinet door assembly together enclose an internal cabinet cavity between the cabinet base 1100 and the cabinet top cover 1600. The top surface of the cabinet top cover 1600 includes a central region and a peripheral region surrounding the central region. At least a portion of the peripheral region is configured as an inclined surface, thus allowing rainwater to be diverted using the inclined surface of the peripheral region.

[0075] In one embodiment, a ventilation chamber 1110 is formed inside the cabinet base 1100, and the ventilation chamber 1110 of the cabinet base 1100 is connected to the cabinet interior chamber of the base cabinet 1000. In one embodiment, the ventilation chamber 1110 includes an air collecting groove 1111 and a plurality of unit air holes 1112. The cabinet base 1100 includes a cabinet base plate 1120 and an annular frame 1130 disposed on the cabinet base plate 1120. The cabinet base plate 1120 and the annular frame 1130 enclose the air collecting groove 1111. A plurality of unit air holes 1112 are formed on the annular frame 1130 along the annular circumference of the annular frame 1130. The plurality of unit air holes 1112 are all connected to the air collecting groove 1111. In the direction away from the air collecting groove 1111, the diameter of the unit air holes 1112 gradually increases.

[0076] The basic cabinet 1000 also includes a file box 1510. The file box 1510 includes a main board 1511 and two connecting plates 1512 disposed on both sides of the main board 1511.
