[0002] An outdoor energy storage cabinet is a device used in outdoor environments and is usually used to store batteries and other energy-related equipment. It provides reliable power support for outdoor activities, outdoor operations, outdoor emergency backup power supplies, and other scenarios. The main function of an outdoor energy storage cabinet is to provide energy buffering, provide energy when needed, and ensure the stable operation of the circuit. For example, when the power supply in the circuit fails or the voltage fluctuates, the outdoor energy storage cabinet can quickly provide energy to keep the circuit stable.

[0003] In the prior art, the design layout of the outdoor energy storage cabinet is not compact and occupies a large space, resulting in the outdoor energy storage cabinet being large in size and heavy in weight, which is not conducive to transportation and carrying. Based on this, the present invention designs a compact outdoor energy storage cabinet. Summary of the invention

[0004] In view of the problems and shortcomings of the prior art, the present invention provides an outdoor energy storage cabinet with a compact structure.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0007] A first longitudinal support rod is evenly spaced and fixed between the front and rear sides of the second vertical frame along the vertical direction, and a second longitudinal support rod corresponding to the first longitudinal support rod is evenly spaced and fixed between the front and rear sides of the third vertical frame along the vertical direction, and a horizontally placed battery pack is placed and supported on each of the first longitudinal support rod and the corresponding second longitudinal support rod, and a horizontally placed battery pack is placed and supported below the first longitudinal support rod and the second longitudinal support rod at the bottom of the right battery cabinet chamber, so that the right battery cabinet chamber is sequentially arranged with a plurality of horizontally placed battery packs from bottom to top;

[0008] Two third longitudinal support rods are fixed at intervals along the vertical direction between the front and rear sides of the first vertical frame, and fourth longitudinal support rods corresponding to the third longitudinal support rods are fixed at intervals along the vertical direction between the front and rear sides of the second vertical frame. A vertically placed high-voltage control box is placed and supported at the bottom of the left electrical cabinet room and below the third and fourth longitudinal support rods at the bottom, a vertically placed liquid cooler is placed and supported on the third and fourth longitudinal support rods at the bottom, and a horizontally placed fire-fighting main engine is placed and supported on the third and fourth longitudinal support rods at the top, so that the left electrical cabinet room is arranged with a high-voltage control box, a liquid cooler and a fire-fighting main engine in sequence from bottom to top.

[0009] The positive and progressive effects of the present invention are:

[0010] The present invention divides the energy storage cabinet into a left electrical cabinet room and a right battery cabinet room.
