Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a compatible module compartment that adapts to multiple models of rectifier modules. Background Technology

[0002] Current high-voltage DC power supply systems convert three-phase medium-voltage AC mains power into multi-winding low-voltage three-phase AC power via a medium-voltage switch and a phase-shifting transformer. This AC power is then fed into multiple parallel rectifier modules via low-voltage switches. The outputs of all rectifier modules are connected to the positive and negative DC buses, and then distributed to the load and battery bank via DC power distribution. In other words, current high-power DC power supply is achieved through the parallel connection of numerous rectifier modules.

[0003] Currently, rectifier modules with different power ratings on the market, such as 20KW, 30KW, 40KW, and the future 60KW and 80KW rectifier modules, have different external dimensions, especially in height. Rectifier modules with the same power rating from different manufacturers may also have different external dimensions, for example, Shenghong and Yingkerui's 40KW rectifier modules.

[0004] Currently, the rectifier module compartment of a charging pile with the same power can only be matched with one model of rectifier module from one manufacturer. If it is necessary to change the rectifier module model or rectifier module manufacturer, the rectifier module compartment of the charging pile needs to be redesigned, which not only wastes resources, but also makes the design task heavy and the production efficiency low for the charging pile manufacturer. Utility Model Content

[0005] To address the problem in the background technology that the rectifier module compartment of charging piles cannot be used in conjunction with multiple types of rectifier modules, this utility model proposes a compatible module compartment that can be used with multiple types of rectifier modules.

[0006] The technical solution of this utility model is: a compatible module compartment for adapting to multiple models of rectifier modules, including a box and a support frame disposed inside the box. The left and right side plates of the box are provided with a transparent mounting groove that matches the size of the support frame.

[0007] The support frame includes two rear columns spaced apart on the left and right and two front columns spaced apart on the left and right. The front columns are located directly in front of the rear columns. The upper and lower ends of the rear columns and the front columns are connected to the upper and lower side plates of the box body, respectively. The rear columns and the front columns are located on the front and rear outer sides of the mounting groove.

[0008] Several right support plates with adjustable height are detachably connected between the rear and front pillars on the right side. Several left support plates with adjustable height are detachably connected between the rear and front pillars on the left side. The left and right support plates are corresponding to each other, and a support plate is detachably connected between the corresponding left and right support plates. A rectifier module is installed on the support plate and is located in the mounting slot.

[0009] Preferably, the vertical cross-sectional structure of the pallet along the front-to-back direction is a U-shaped structure with an opening at the top.

[0010] Preferably, one to three trays can be connected side by side between the left and right support plates, and the front and rear widths of the left and right support plates match the total width of the multiple trays arranged side by side.

[0011] Preferably, when the number of trays that can be installed side by side in the mounting slot is greater than 3, vertically arranged reinforcing columns are provided between the two rear columns on the left and right sides and the front column, and the upper and lower ends of the reinforcing columns are connected to the upper and lower side plates of the box body respectively.

[0012] Left support plates can be detached between each pair of adjacent front columns, reinforced columns, and rear columns on the left side, and right support plates can be detached between each pair of adjacent front columns, reinforced columns, and rear columns on the right side.

[0013] Preferably, the front column, reinforced column, or rear column are marked with labels indicating the installation positions of rectifier modules of different heights.

[0014] Preferably, both ends of the pallet are bent downwards to form hook plates, the pallet overlaps the left and right support plates, and the hook plates on the left and right sides are hooked to the outside of the left and right support plates respectively.

[0015] Preferably, the upper ends of adjacent front and rear columns are each detachably connected to a vertically arranged upper sealing plate, and the lower ends of adjacent front and rear columns are each detachably connected to a vertically arranged lower sealing plate.

[0016] Alternatively, vertically arranged upper sealing plates can be detachably connected between the upper ends of each pair of adjacent front columns, reinforced columns, and rear columns, and vertically arranged lower sealing plates can be detachably connected between the lower ends of each pair of adjacent front columns, reinforced columns, and rear columns.

[0017] The upper sealing plate is used to seal the gap between the top rectifier module and the top of the mounting slot, and the lower sealing plate is used to seal the gap between the bottom rectifier module and the bottom of the mounting slot.

[0018] The advantages of this invention are: This invention allows for adjustment of the vertical installation positions of the left support plate, right support plate, and tray according to different specifications of rectifier modules, thereby adjusting the layer height between adjacent trays. It can also be adapted to meet the installation requirements of rectifier modules with different front-to-back widths by replacing trays with trays of varying front-to-back widths.

[0019] When the number of rows of rectifier modules installed in front and behind is less than 3, the trays can be installed side by side on the same left and right support plates, saving costs.

[0020] When the number of rectifier modules installed in rows is greater than three, a reinforcing column can be installed between the front and rear columns, and left and right support plates can be installed between each pair of adjacent front, reinforcing, and rear columns. Based on the double and triple rows of the tray, the number of rows of compatible rectifier modules can be stacked sequentially to achieve four rows (double row + double row), five rows (double row + triple row), six rows (triple row + triple row), seven rows (double row + double row + triple row), etc. Theoretically, unlimited expansion can be achieved, avoiding redundant design and making production more convenient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: A compatible module compartment for multiple rectifier module models. This example uses a single-row compatible module compartment for mounting a 40kW rectifier module 8 as an example. Figure 4 and Figure 5 As shown, it includes a housing 11 and a support frame disposed inside the housing 11. Both the left and right side panels of the housing 11 are provided with a transparent mounting groove that matches the size of the support frame.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the support frame includes two rear columns 1 spaced apart on the left and right and two front columns 2 spaced apart on the left and right. The front columns 2 are located directly in front of the rear columns 1. The upper and lower ends of the rear columns 1 and the front columns 2 are respectively connected to the upper and lower side plates of the box body 11. The rear columns 1 and the front columns 2 are located on the front and rear outer sides of the mounting groove.

[0034] like Figure 1As shown, several adjustable internal threaded holes are provided on both the rear column 1 and the front column 2 on both sides. Several right support plates 4 are provided between the rear column 1 and the front column 2 on the right side, and several left support plates 5 are provided between the rear column 1 and the front column 2 on the left side. The left support plates 5 and the right support plates 4 are aligned left and right. The left and right ends of the right support plates 4 and the left support plates 5 are provided with mounting screw holes. The mounting screw holes can be aligned with any one of the adjustable internal threaded holes in the same column. The right support plates 4 and the left support plates 5 are detachably installed between the rear column 1 and the front column 2 by adjusting screws that pass through the mounting screw holes and the adjustable internal threaded holes, so that the vertical position of the right support plates 4 and the left support plates 5 on the rear column 1 and the front column 2 is adjustable to adapt to the installation requirements of rectifier modules 8 of different height specifications.

[0035] The left support plate 5 and the right support plate 4 are detachably connected by bolts to each other with a support plate 3. Specifically, the left and right ends of the support plate 3 are bent downward to form hook plates. The support plate 3 overlaps the left support plate 5 and the right support plate 4. The hook plates on the left and right sides are hooked on the outside of the left support plate 5 and the right support plate 4 respectively, and the hook plates on the left and right sides are detachably connected to the left support plate 5 and the right support plate 4 respectively by bolts.

[0036] A rectifier module 8 is mounted on the tray 3, and the rectifier module 8 is located in the mounting slot. To quickly identify the upper and lower mounting positions of the left support plate 5 and right support plate 4, which accommodate rectifier modules 8 of different specifications, in this embodiment, markings 10 are provided on the rear column 1 and front column 2 for the mounting positions of rectifier modules 8 of different height specifications. For ease of production, such as... Figure 2 As shown, in this embodiment, the identifier 10 is a slightly smaller diameter identification hole drilled next to the adjustment internal thread hole corresponding to the installation position of the 40KW rectifier module 8, to distinguish it from the adjustment internal thread hole of the 20KW and 30KW rectifier modules 8 (which are basically the same size). Figure 6 As shown, the same set of compatible module compartments can be adapted to the installation requirements of rectifier modules 8 from different manufacturers and with different power by adjusting the height of the left support plate 5 and the right support plate 4.

[0037] To limit the forward and backward movement of the rectifier module 8 on the tray 3 and to guide the installation of the rectifier module 8, such as Figure 1 As shown, in this embodiment, the vertical cross-sectional structure of the support plate 3 along the front-to-back direction is a U-shaped structure with an upward opening (i.e., both the front and rear ends of the support plate 3 have upward-facing flanges). The left and right ends of the support plate 3 are both downward-facing flanges and are bolted to the left support plate 5 and the right support plate 4, respectively.

[0038] To prevent wind short circuits and improve overall aesthetics, such as Figure 2 , Figure 3 and Figure 4 As shown, the upper ends of adjacent front columns 2 and rear columns 1 are detachably connected by bolts to vertically arranged upper sealing plates 6, and the lower ends of adjacent front columns 2 and rear columns 1 are detachably connected by bolts to vertically arranged lower sealing plates 7. The upper sealing plates 6 are used to seal the gap between the uppermost rectifier module 8 and the top of the mounting slot, and the lower sealing plates 7 are used to seal the gap between the lowermost rectifier module 8 and the bottom of the mounting slot.

[0039] Working principle: First, fix the front column 2 and the rear column 1 inside the housing 11 and on the front and rear outer layers of the mounting slot. Then, according to the size of the compatible module 8, connect and fix the left support plate 5, the tray 3, and the right support plate 4 of each layer between the front column 2 and the rear column 1. Install the upper sealing plate 6 and the lower sealing plate 7 between the upper and lower ends of the front column 2 and the rear column 1 to seal the gaps. Finally, install the compatible module 8.

[0040] Example 2: A compatible module module compartment for multiple rectifier module models. This example differs from Example 1 in that... Figure 8 As shown, three support plates 3 can be connected side-by-side between the left support plate 5 and the right support plate 4, and the front and rear widths of the left support plate 5 and the right support plate 4 match the total width of the three support plates 3 arranged side-by-side. Other structures are the same as in Embodiment 1.

[0041] Example 3: A compatible module compartment for multiple rectifier modules. This example differs from Example 1 in that two trays 3 can be connected side-by-side between the left support plate 5 and the right support plate 4, and the front-to-back widths of the left support plate 5 and the right support plate 4 match the total width of the two trays 3 arranged side-by-side. Other structural features are the same as in Example 2.

[0042] Example 4: A compatible module compartment for multiple rectifier modules. This example differs from Example 1 in that the mounting slot in this example can accommodate five trays 3 installed side-by-side. To prevent the left support plate 5 and right support plate 4 from becoming too long and deforming under excessive load, when the number of trays 3 installed side-by-side exceeds three, reinforcing columns 9 need to be installed. Multiple left support plates 5 and right support plates 4 are arranged side-by-side to distribute the pressure. Specifically, as shown... Figure 7 As shown, vertically arranged reinforcing columns 9 are provided between the two rear columns 1 on the left and right and the front column 2 at intervals. The upper and lower ends of the reinforcing columns 9 are connected to the upper and lower side plates of the box body 11, respectively.

[0043] The reinforced column 9 is provided with an adjustment internal thread hole of the same size and position as the front column 2 and the rear column 1. The left side of the front column 2, reinforced column 9 and rear column 1 are all detachably connected by bolts to each other. The right side of the front column 2, reinforced column 9 and rear column 1 are all detachably connected by bolts to each other.

[0044] The upper ends of each pair of adjacent columns 2, 9 and 1 are detachably connected by bolts to a vertically arranged upper sealing plate 6, and the lower ends of each pair of adjacent columns 2, 9 and 1 are detachably connected by bolts to a vertically arranged lower sealing plate 7.

[0045] Based on the above method, the number of rectifier modules installed in the compatible module compartment can be stacked sequentially, using the two-row and three-row configurations of the tray as a baseline, to achieve four rows (two rows + two rows), five rows (two rows + three rows), six rows (three rows + three rows), seven rows (two rows + two rows + three rows), etc., theoretically allowing for unlimited expansion. All other structures are the same as in Example 1.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
