DETAILED DESCRIPTION

[0028] The following describes the implementation of the present patent application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present patent application from the content disclosed in this specification. The present patent application can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present patent application. It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict.

[0029] See also Figure 1-11 , the utility model provides the following technical solutions:

[0030] An external structure of an energy storage cabinet, such as Figure 1 and Figure 2 As shown, it includes a cabinet 1 and a PCS cabinet 2 hung on the outer wall of the cabinet 1. The lead wires at the lower end of the PCS cabinet 2 are arranged along the side wall of the cabinet 1 and penetrate from the bottom of the cabinet 1 into the cabinet 1 to connect with the electrical components. A shield 3 is installed on the side wall of the cabinet 1, which is located directly below the PCS cabinet 2 and is used to hide the lead wires. To save the inner cavity space of the cabinet 1, the lead wires of the PCS cabinet 2 enter the cabinet through the shield and the wire trough. The shield 3 is used to protect the lead wires. The threading holes on the cable limit plate 4 make the wiring neat.

[0031] As a preferred embodiment of this case, Figure 1 As shown, the lower end of the cabinet 1 is connected to the base 11, and the installation height of the cabinet 1 is adjusted to prevent rain erosion. The lower end of the shield 3 extends downward and is flush with the lower end surface of the side wall of the base 11. The base 11 is plugged with a number of wire slots 5 for routing the lead wires. Figure 6As shown, the base 11 is a support base formed by connecting a plurality of channel steels to form a mesh structure, and a plurality of rows of rectangular holes are provided on the end surface of the support base perpendicular to the shield 3. The wire trough 5 is passed through the rectangular holes, and connecting plates 51 are vertically installed on both sides of one end of the wire trough 5 facing the shield 3. The connecting plates 51 are fastened to the outer wall of the base 11 by bolts, and a wire entry hole located directly above the wire trough 5 is provided at the bottom of the cabinet 1.

[0032] like Figure 2 As shown, the side wall of the cabinet 1 is installed with a plurality of horizontally arranged cable limit plates 4 for limiting the lead-out wires. The cable limit plates 4 include a plate body in a Z-shaped structure. After the Z-shaped structure plate body is rotated 90° counterclockwise, the end face that fits the cabinet 1 is locked on the side wall of the cabinet 1. The end face of the Z-shaped structure plate body that does not contact the side wall of the cabinet 1 is provided with a plurality of threading holes 41 for the lead-out wires to pass through and position.

[0033] As attached Figure 1-2 and Figure 7 As shown, an assembly part 6 is installed between the PCS cabinet 2 and the cabinet body 1 to realize a detachable connection. Specifically, the assembly part 6 includes two vertically parallel square tubes 61 and four plug-in connectors 62. A fixing plate 63 is connected between the two square tubes 61. It should be noted that the square tube 61 and the fixing plate 63 are arranged vertically. The square tube 61 is connected to the side wall of the cabinet body 1, and the plug-in connector 62 is fixed to the side wall of the PCS cabinet 2. Through the assembly part 6, the PCS cabinet 2 can be quickly disassembled and assembled relative to the cabinet body 1.

[0034] For some examples, see Figure 8-11 The connector 62 includes a strip plate 621 and a plug-in plate 622 connected to one side of the strip plate 621 and having an inverted L-shaped structure. A card slot 611 corresponding to the plug-in plate 622 is opened on the square tube 61. The PCS cabinet 2 is hung on the cabinet body 1 by plugging the plug-in plate 622 into the card slot 611. A rib plate 623 for improving the stability of the connector 62 is connected between the vertical section of the plug-in plate 622 and the side wall of the strip plate 621. The strip plate 621, the plug-in plate 622 and the rib plate 623 are an integrated molding structure. The integrated structure is stable and firm. The strip plate 621, the plug-in plate 622 and the rib plate 623 have the same width.

[0035] In this embodiment, it should be noted that the card slot 621 is an inverted convex structure, the width of the plug-in board 622 matches the notch at the lower end of the card slot 621, and the width of the notch at the upper end of the card slot 621 is larger than the width of the plug-in board 622, so that the plug-in board 622 can be easily inserted into the card slot 621 without jamming.

[0036] In some examples, such as Figure 8As shown, the inner wall of the square tube 61 is integrally connected with a support block 612 located at the lower end of the slot 611 and abutting against the vertical section of the plug board 622. The vertical section of the plug board 622 is close to the strip plate 621 and has a sloped structure that gradually becomes thicker from bottom to top. Fig.10 and 11 As shown, when the plug-in board 622 passes through the slot 611 and moves down to abut against the support block 612, the strip plate 621 is closely attached to the square tube 61. The strip plate 621 is closely attached to the outer wall of the square tube 62, so that the hanging structure of the plug-in 62 and the square tube 61 is stable, and the stability of the external device is improved.

[0037] In this embodiment, a first positioning hole is opened on the side wall of the square tube 61 opposite to the slot 611, and the first positioning hole and the slot 611 are located on the same horizontal plane and correspond one to one. The square tube 61 is passed through the slot 611 by a first positioning screw and aligned with the first positioning hole and locked on the cabinet 1.

[0038] In this embodiment, the slot 611 can not only be used for hanging the connector 62, but also allow the positioning screw to pass through it for installation, and at the same time, provide space for convenient use of tools to operate the positioning screw.

[0039] It should be noted that a number of second positioning holes are provided on the strip plate 621, and the connector 2 is locked on the side wall of the PCS cabinet 2 by passing through the second positioning screws through the second positioning holes. The second positioning holes are provided on the side wall of the strip plate 621 at the horizontal projection position of the non-plug-in plate 622, without any obstruction, and convenient operation.

[0040] During actual installation and use, the two square tubes 61 are first connected and fixed by the fixing plate 63, and then the first positioning screw is passed through the card slot 611 and screwed into the first positioning hole to lock and fix it on the cabinet body 1, and then the position of the connector 62 is measured on the PCS cabinet 2, and the connector 62 is passed through the second positioning hole and locked on the PCS cabinet 2 by the second positioning screw. Finally, the PCS cabinet 2 is lifted, and the plug-in board 622 on the connector 62 is inserted along the slot 611. The inclined surface of the plug-in board 622 gradually fits with the support block 612 during the downward movement. The inclined surface structure will push the plug-in board 622 to move toward the inside of the square tube 61, so that the strip plate 621 is close to the outer wall of the square tube 61, thereby making the hanging structure of the connector 62 and the square tube 61 stable, thereby improving the stability of the external equipment. At the same time, the rib plate 623 is placed on the bottom of the card slot 611 whose width matches it to prevent the PCS cabinet 2 from shaking.

[0041] The above embodiments are merely illustrative of the principles and effects of this patent application, and are not intended to limit this patent application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
