DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Please also read Figure 1 , Figure 2 and Figure 4, the cabinet wiring port installation structure provided by the utility model is now described. The cabinet wiring port installation structure includes a sealing plate 1, a mounting plate 2 and a fireproof foam 3. The sealing plate 1 is provided with a wiring port 11; the mounting plate 2 is arranged on the sealing plate 1 and blocks the wiring port 11; the mounting plate 2 is provided with a first avoidance hole 21; the fireproof foam 3 is arranged on the mounting plate 2 and is located in the wiring port 11, and the fireproof foam 3 is provided with a second avoidance hole 31; wherein the first avoidance hole 21 and the second avoidance hole 31 are both used to allow the copper bus 5 to pass through.

[0036] The cabinet wiring port installation structure of this embodiment is applied to a cabinet, and electronic devices are arranged inside the cabinet, and the cabinet needs to be connected to external devices through the copper bus 5. For example, the energy storage converter cabinet 6 needs to be connected to the bus cabinet through the copper bus 5, and the transformer 7 needs to be connected to the bus cabinet through the copper bus 5. This embodiment does not limit the specific functions of the cabinet.

[0037] The sealing plate 1 is a side plate of the cabinet, and can be any one of the front side plate, the rear side plate, the left side plate, and the right side plate. The wiring port 11 on the sealing plate 1 is used to allow the copper busbar 5 to pass through. In order to prevent the copper busbar 5 from being exposed, in the prior art, a wiring cabinet is provided on the periphery of the copper busbar 5, and the wiring cabinet blocks the wiring port 11. Since the wiring cabinet is buckled at the wiring port 11, there is a problem of poor sealing.

[0038] The mounting plate 2 fits the sealing plate 1, but is not buckled, so that the mounting plate 2 can block the wiring port 11. It should be noted that the blocking defined here means that after the copper busbar 5 passes through the wiring port 11, the mounting plate 2 just blocks the remaining space of the wiring port 11. Preferably, the mounting plate 2 is an insulating plate made of epoxy resin.

[0039] The fireproof foam 3 is arranged at the wiring port 11 and is placed in the wiring port 11 with the help of the mounting plate 2. The fireproof foam 3 is fixed on the mounting plate 2, which can simplify the installation of the fireproof foam 3 and improve the assembly efficiency of the wiring port installation structure of the cabinet. Of course, in order to further improve the fireproof performance of the cabinet, the fireproof foam 3 can be bonded to the entire inner wall of the sealing plate 1. The fireproof foam 3 itself has fireproof performance and can block flames.

[0040] The copper busbar 5 is generally a rectangular sheet structure. In general, the cabinet is connected to the external cabinet through three groups of copper busbars 5. Correspondingly, there are three first avoidance holes 21 and three second avoidance holes 31, and the hole height of the first avoidance hole 21 is slightly larger than the width of the copper busbar 5, and the hole width of the first avoidance hole 21 is slightly larger than the thickness of the copper busbar 5. In other words, there is a small gap between the copper busbar 5 and the hole wall of the first avoidance hole 21. Figure 1 shown.

[0041] Preferably, the second avoidance hole 31 overlaps with the first avoidance hole 21 .

[0042] Compared with the prior art, the cabinet wiring port installation structure provided by the utility model is characterized in that a mounting plate 2 is arranged on a sealing plate 1, which is used to block the wiring port 11 to prevent impurities such as water, oil, and dust from entering the interior of the cabinet through the wiring port 11, and can also isolate the copper bus 5 from the sealing plate 1, thereby improving the safety performance of the connection of the copper bus 5; a fireproof foam 3 is also arranged at the wiring port 11, and the fireproof foam 3 plays a role in isolating flames, so that the wiring port 11 has fireproof performance and prevents flames from entering the interior of the cabinet through the wiring port 11; in addition, the fireproof foam 3 is arranged on the mounting plate 2, which can simplify the installation operation of the fireproof foam 3 and improve the assembly efficiency of the cabinet wiring port installation structure.

[0043] In some embodiments, the mounting plate 2 may be used as follows: Figure 1 and Figure 4 The mounting structure shown is shown in Figure 1 and Figure 4 The mounting plate 2 is located on the inner side of the sealing plate 1 , and the outer edge of the mounting plate 2 is fixedly arranged on the periphery of the wiring port 11 .

[0044] The mounting plate 2 is connected to the inner side of the sealing plate 1. On the one hand, it does not occupy the external space of the cabinet and does not affect the external aesthetics of the cabinet. On the other hand, it can be directly fastened to the sealing plate 1 by screws, which is convenient for assembly with the sealing plate 1. Preferably, in order to optimize the structure of the mounting plate 2, the outer dimensions of the mounting plate 2 are slightly larger than the diameter of the wiring port 11.

[0045] It should be noted that the “inside” and “outside” defined in this embodiment refer to the orientation of the cabinet itself, wherein “inside” refers to the inside of the cabinet, and “outside” refers to the outside of the cabinet.

[0046] In some embodiments, the fireproof foam 3 is attached to the mounting plate 2, that is, the fireproof foam 3 is placed in the wiring port 11 with the aid of the mounting plate 2. Specifically, the fireproof foam 3 is adhered to the mounting plate 2 by means of adhesive.

[0047] Compared with the method in which the fireproof foam 3 itself is fixed to the wiring port 11, the fireproof foam 3 is bonded to the mounting plate 2, which improves the fixing strength of the fireproof foam 3, simplifies the fixing operation of the fireproof foam 3, and can also ensure the stable fixing performance of the fireproof foam 3.

[0048] In some embodiments, the above cabinet wiring port installation structure can also be used as follows: Figure 3 The structure shown, see Figure 3 The periphery of the wiring port 11 is connected to a wiring housing 4 , and the wiring housing 4 is located outside the sealing plate 1 .

[0049] The wiring housing 4 is covered on the outside of the copper busbar 5 extending out of the wiring port 11 to prevent the copper busbar 5 from being exposed and eliminate potential safety hazards. In addition, the wiring housing 4 is also buckled at the wiring port 11 to block the wiring port 11 and prevent impurities such as water, oil, and dust from entering the wiring port 11.

[0050] In some embodiments, the sealing plate 1 may be used as follows: Figure 2 and Figure 4 The structure shown, see Figure 2 and Figure 4 A connection frame 12 is provided on the outer side of the sealing plate 1 at the periphery of the wiring port 11 ; the connection frame 12 is connected to the wiring housing 4 .

[0051] Since the wiring housing 4 is a three-dimensional structure and has an inner cavity, if one end of the wiring housing 4 is directly fixed on the sealing plate 1, it is necessary to fasten the screws on the inner side of the sealing plate 1 to connect it with the end face of the wiring housing 4. Since the mounting plate 2 is also installed on the inner side of the sealing plate 1, and the mounting plate 2 blocks the wiring port 11, if the sealing plate 1 and the wiring housing 4 are directly connected by screws, there will be problems of blind installation and long alignment operation time. In addition, there are many copper bars 5 distributed on the inner side of the wiring port 11. Tightening the screws on the inner side of the sealing plate 1 is also inconvenient.

[0052] In order to solve the above problems, in this embodiment, a connecting frame 12 is provided on the outer surface of the sealing plate 1, and the connecting frame 12 protrudes to the outside of the sealing plate 1. The connecting frame 12 is connected to the wiring housing 4 by screws, and the tightening operation of the screws is performed on the outside of the sealing plate 1. There is no problem of blind installation and long alignment time, and the copper busbar 5 will not affect the tightening operation, thereby facilitating the assembly operation of the wiring housing 4.

[0053] Preferably, one end of the wiring housing 4 is covered on the connecting frame 12, and the wiring housing 4 is connected to the connecting frame 12 in a direction perpendicular to the plate surface of the sealing plate 1. Specifically, the wiring housing 4 and the connecting frame 12 are connected by screws, and the axial direction of the screws is perpendicular to the plate surface of the sealing plate 1.

[0054] The wiring housing 4 is covered on the connecting frame 12 , and blocks the connecting frame 12 by covering, thereby blocking the wiring port 11 , thereby improving the sealing performance at the wiring port 11 .

[0055] See also Figure 2 , Figure 4 and Figure 5 On the basis of the above embodiment, the wiring port 11 is a rectangular hole; the connecting frame 12 includes a rectangular extension frame 121 and a flange 122 connected to the periphery of the rectangular extension frame 121; the wiring housing 4 is a hexahedral structure, and a connecting plate 41 is provided inside one end of the wiring housing 4, and the connecting plate 41 is fixedly connected to the flange 122 along a direction perpendicular to the plate surface of the sealing plate 1.

[0056] The rectangular extension frame 121 is used to connect with the sealing plate 1 . The inner end of the rectangular extension frame 121 can be formed into a snap-fitting portion that folds outward. The snap-fitting portion has a snap-fitting right angle. One side wall of the snap-fitting right angle abuts against the side wall of the wiring port 11 , and the other side wall of the snap-fitting right angle abuts against the inner side surface of the sealing plate 1 .

[0057] The flange 122 is used to connect with the wiring housing 4. The flange 122 is folded outward relative to the rectangular extension frame 121 so that the connection between the flange 122 and the wiring housing 4 is located outside the rectangular extension frame 121, thereby facilitating the screw tightening operation.

[0058] The connecting plate 41 is arranged inside the wiring housing 4 , which can meet the connection with the flange 122 and also enable the wiring housing 4 to meet the installation requirements of being covered on the connection frame 12 .

[0059] Based on the same inventive concept, an embodiment of the present application also provides an energy storage converter cabinet 6, including the above-mentioned cabinet wiring port installation structure; wherein, the periphery of the wiring port 11 is connected to a wiring shell 4, and the wiring shell 4 is located on the outside of the sealing plate 1.

[0060] The energy storage converter cabinet 6 provided by the present invention adopts the above cabinet wiring port installation structure, which can block the wiring port 11, improve the sealing performance of the cabinet, and increase the fireproof ability of the cabinet itself.

[0061] See also Figure 6 Based on the same inventive concept, the embodiment of the present application also provides an inverter boost device, including a transformer 7 and the above-mentioned energy storage converter cabinet 6. A wire outlet is provided on the side wall of the transformer 7; one end of the wiring housing 4 is connected to the wiring port 11, and the other end of the wiring housing 4 is connected to the wire outlet.

[0062] The transformer 7, the energy storage converter cabinet 6 and the wiring housing 4 are all arranged on the support base. The transformer 7 converts the DC power supply into the AC power supply. The transformer 7 is connected to the energy storage converter cabinet 6 through the copper bus 5, and the wiring housing 4 is covered on the outside of the copper bus 5.

[0063] In the prior art, a line outlet is provided on the cabinet side wall of the transformer 7, a wiring port 11 is provided on the cabinet side wall of the energy storage converter cabinet 6, one end of the wiring housing 4 is connected to the line outlet, and the other end is connected to the wiring port 11. Since the transformer 7 is a high-heat-generating device, and a fan is provided inside the energy storage converter cabinet 6, the heat inside the transformer 7 will enter the energy storage converter cabinet 6 through the line outlet, the wiring housing 4, and the wiring port 11, causing heat reflux, affecting the heat dissipation performance of the energy storage converter cabinet 6. The installation plate 2 is provided at the wiring port 11, which also plays a role in blocking the passage of heat.

[0064] Compared with the prior art, the inverter boost device provided by the present invention has the mounting plate 2 and the fireproof foam 3 which not only have the properties of blocking impurities and preventing fire, but also can block heat, thereby preventing the heat emitted by the transformer 7 from flowing back into the energy storage converter cabinet 6, and will not affect the heat dissipation of the energy storage converter cabinet 6 itself.

[0065] In some embodiments, the above-mentioned inverter boost device can also be used as follows Figure 6 The structure shown, see Figure 6 There are two groups of energy storage converter cabinets 6 , which are electrically connected, and a connection port 11 is provided on the cover plate 1 of one group of energy storage converter cabinets 6 .

[0066] The two groups of energy storage converter cabinets 6 can be arranged side by side or spaced apart in the front-to-back direction. The specific distribution method depends on the installation site. The two groups of energy storage converter cabinets 6 are electrically connected to the transformer 7 respectively, which can also be understood as two groups of energy storage converter cabinets 6 are connected in parallel. When one group of energy storage converter cabinets 6 is maintained, the other group of energy storage converter cabinets 6 can still be electrically connected to the transformer 7 without affecting the operation of the inverter boost device.

[0067] It should be noted that the connecting mechanical structure for electrically connecting the two groups of energy storage converter cabinets 6 and the transformer 7 is located inside one group of the energy storage converter cabinets 6. In this way, it is only necessary to open a wiring port 11 on the cover plate 1 of the group of energy storage converter cabinets 6 and to set a mounting plate 2 and a fireproof foam 3 at the wiring port 11.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
