In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.
[0029] In the embodiments of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the communication or interaction relationship between two elements. For ordinary skilled persons in the art, the specific meanings of the above terms in the embodiments of the utility model can be understood according to specific circumstances.
[0030] As shown in Figure 1 and Figure 2 , a kind of power supply cabinet structure of distribution, including cabinet frame 100, cabinet frame 100 includes support 110 and at least one layer frame 120, each layer frame 120 is spaced apart in support 110, each layer frame 120 is provided with a liquid receiving box 130, and the outer side wall of liquid receiving box 130 is connected with the inner side wall of layer frame 120, in any one liquid receiving box 130, liquid receiving box 130 inner bottom wall is provided with drain hole 131, and the inner bottom wall of liquid receiving box 130 is inclined downward to the direction close to drain hole 131.
[0031] It should be noted that support 110 is rectangular parallelepiped structure, for example, support 110 is formed by welding several square tubes.In support 110, a plurality of layer frames 120 are arranged along the horizontal direction. The layer frames 120 are spaced apart. Further, a liquid receiving box 130 is installed in each layer frame 120. The inner bottom wall of the liquid receiving box 130 is provided with a drain hole 131, and the inner bottom wall of the liquid receiving box 130 is inclined downward to the direction close to the drain hole 131. In this way, when the battery is placed on the layer frame 120 for distribution testing, if the battery leaks, the electrolyte falls into the liquid receiving box 130. Because the inner bottom wall of the liquid receiving box 130 is inclined downward to the direction close to the drain hole 131, the electrolyte will flow to the drain hole 131 and eventually flow out of the liquid receiving box 130 from the drain hole 131. Compared with the existing horizontal structure, the liquid receiving box 130 of the present application does not need to be removed from the layer frame 120 for cleaning, but can be reliably discharged from the drain hole 131, which is convenient to use.
[0032] In an embodiment, the inclination angle of the inner bottom wall of the liquid receiving box 130 is 5°, so that the electrolyte in the liquid receiving box 130 can reliably flow out along the drain hole 131.
[0033] As shown in Figure 1 and Figure 2 , in an embodiment, the layer frame 120 includes an outer frame 121 and an inner frame 122, the outer frame 121 is arranged on the support 110, the inner frame 122 is arranged on the inner side of the outer frame 121, and a space is provided between the inner frame 122 and the outer frame 121.

The liquid receiving box 130 is installed on the inner side wall of the inner shelf 122. In this way, the shelf 120 with a double frame structure has stronger structural strength, so as to be able to support a battery with greater weight. In an embodiment, the outer side wall of the liquid receiving box 130 is welded with the inner side wall of the inner shelf 122. In this way, since the inner bottom wall of the liquid receiving box 130 is an inclined structure, it is not necessary to disassemble it for cleaning. In order to improve the structural strength of the liquid receiving box 130, the liquid receiving box 130 is welded and fixed on the inner shelf 122.
[0035] As shown in Figure 1 , in an embodiment, a plurality of filling shells 123 are arranged between the outer shelf 121 and the inner shelf 122.
[0036] It should be noted that the filling shell 123 is arranged between the outer shelf 121 and the inner shelf 122, and the filling shell 123 is a thin shell structure, which is convenient for installing lines subsequently. Specifically, the lines can be installed between the inner shelf 122 and the outer shelf 121, and then covered by the filling shell 123.
[0037] As shown in Figure 1 and Figure 2 , in an embodiment, a reinforcing block 124 is arranged between the outer shelf 121 and the support 110.
[0038] It should be noted that in order to strengthen the structural strength between the shelf 120 and the support 110, the reinforcing block 124 is installed at the joint position of the outer shelf 121 and the support 110. Specifically, the included angle between the outer shelf 121 and the support 110 is a right angle. The reinforcing block 124 is installed at the position of the right angle structure, which can improve the structural strength between the outer shelf 121 and the support 110.
[0039] As shown in Figure 2 , in an embodiment, a plurality of reinforcing rods 125 are arranged at intervals on the inner side wall of the inner shelf 122, and the top surface of the reinforcing rod 125, the top surface of the inner shelf 122 and the top surface of the outer shelf 121 are flush.
[0040] In this way, the top surfaces of the reinforcing rod 125, the inner shelf 122 and the outer shelf 121 form a plane for jointly supporting the battery to be tested. The two ends of the reinforcing rod 125 are welded with the inner side wall of the inner shelf 122, which can further enhance the structural strength of the inner shelf 122.
[0041] As shown in Figure 3 , in an embodiment, a plurality of fixing columns 140 are arranged around the liquid leakage hole 131 of the liquid receiving box 130. Further, in an embodiment, the fixing columns 140 are circumferentially equiangularly distributed around the liquid leakage hole 131.
[0042] It should be noted that the fixing column 140 is welded on the outer bottom wall of the liquid receiving box 130, and the pipeline is in communication with the liquid leakage hole 131 accurately and stably by using the fixing column 140. For example, the fixing column 140 can be a threaded stud structure.
[0043] In an embodiment, three shelves 120 are arranged, and the three shelves 120 are equidistantly distributed. In this way, by arranging multiple shelves 120, for example, three shelves 120, the battery accommodating capacity of the power supply cabinet is improved.
[0044] As shown in Figure 1 In an embodiment, a side shelf 150 is arranged on one side of the support 110, and a partition plate 160 is arranged between the side shelf 150 and the support 110.
[0045] It should be noted that the side shelf 150 is arranged on one side of the support 110, and the side shelf 150 is used for mounting the power supply system. In addition, the partition plate 160 is arranged between the side shelf 150 and the support 110, and the test area in the support 110 and the power supply area in the side shelf 150 are separated by the partition plate 160, so that the two areas are relatively independent.
[0046] The above embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. In the utility model, the installation / fixing / arrangement can be understood as including but not limited to the locking and fixing by using screws, unless otherwise defined.
