[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figures 1 to 6 The embodiment of the present application provides an outdoor energy storage cabinet, including an energy storage inverter 2, a switch box 31, a power control box 32, a liquid cooling system 4, a junction box 5, a battery system 6, an air cooling system 7 and a fire protection system. The energy storage inverter 2 is mounted on the cabinet 1 by fasteners, the switch box 31 and the power control box 32 are arranged in parallel below the energy storage inverter 2, and the switch box 31 and the power control box 32 are mounted in parallel on the cabinet 1 by fasteners; the liquid cooling system 4 is mounted on one side of the energy storage inverter 2 by fasteners, and the junction box 5 is mounted between the energy storage inverter 2 and the liquid cooling system 4 by fasteners; a battery system 6 is arranged below the liquid cooling system 4; the air cooling system 7 is mounted on the back of the cabinet 1 by fasteners; a compartment door 11 is also arranged on the cabinet 1, and a human-computer interaction interface 94 is arranged on the compartment door 11.

[0036] Working principle and effect: By configuring the switch box 31, energy storage converter 2, air cooling system 7, power control box 32, junction box 5, liquid cooling system 4, human-machine interface 94, fire protection system, battery system 6 and other parts inside the outdoor energy storage cabinet, the internal system and equipment are highly modularized. Specifically, the secondary equipment such as circuit breakers and relays are arranged in the switch box 31 and the power control box 32 by adopting an integrated unit design, and the space in the depth direction of the cabinet 1 is fully utilized to achieve the characteristic of small footprint, and the components are modularly arranged, and each module is fixed to the cabinet 1 by fasteners, ensuring that all equipment can be disassembled and maintained, and there is no sequence requirement for the maintenance process, so as to achieve rapid maintenance of the equipment.

[0037] Further, such as Figure 3 As shown, two energy storage converters 2 are provided, and the two energy storage converters 2 are vertically arranged and installed on the cabinet 1 .

[0038] Furthermore, the fasteners may be bolts. When disassembly maintenance is required, the operator first removes the cables on the module panel, then loosens the bolt fasteners to separate the module from the cabinet 1, and finally pulls the module out by holding the hand grip 33, which is simple, convenient and quick to operate.

[0039] Furthermore, in order to better realize the disassembly and replacement of components and equipment, a sheet metal bracket is provided in the cabinet 1, and the two energy storage inverters 2, the junction box 5, the temperature sensor 82, the smoke sensor 83, the liquid cooling system 4, the high-voltage switch box 61, and the five electrical boxes 62 are fixed to the cabinet 1 by fasteners and sheet metal brackets.

[0040] In one embodiment, Figure 2 As shown, the switch box 31 and the power control box 32 are both provided with a hand grip 33. The switch box 31 and the power control box 32 are both integrated designs, and the hand grip 33 is configured thereon. When the operator disassembles and maintains the equipment, after loosening the fasteners, the equipment can be quickly pulled out through the hand grip 33 for easy replacement.

[0041] In one embodiment, Figure 2 and Figure 6 As shown, the liquid cooling system 4 includes a cooling device 41, and a cooling circulation pipe 42 is provided on the cooling device 41. The cooling circulation pipe 42 extends vertically downward along the side wall of the cabinet 1 to the battery system 6. The cooling device 41 generates a coolant, and the coolant circulates in the cooling circulation pipe 42. The cooling circulation pipe 42 extends and surrounds into the battery system 6 to cool the battery system 6, ensuring that the battery releases more electricity in a better environment.

[0042] In one embodiment, Figure 1 and Figure 3As shown, the battery system 6 includes a high-voltage switch box 61 and an electric box 62, and the high-voltage switch box 61 is installed above the electric box 62. The high-voltage switch box 61 is used to control the switch of the electric box 62. Further, the electric box 62 is provided with 5 groups, and the 5 groups of electric boxes 62 are arranged in parallel below the high-voltage switch box 61 in the vertical direction.

[0043] Further, such as Figure 6 As shown, the high voltage switch box 61 is also provided with a handle 33 for easy disassembly.

[0044] In one embodiment, Figures 1 to 3 As shown, the fire protection system includes a fire control box 81, a temperature sensor 82, a smoke sensor 83, an aerosol fire extinguishing device 84 and an audible and visual alarm 85. The fire control box 81 is installed on the inner side of the door 11, and a fire host is arranged in the fire control box 81; the temperature sensor 82 and the smoke sensor 83 are arranged in parallel above the electric box 62; the aerosol fire extinguishing device 84 and the audible and visual alarm 85 are both arranged on the door 11. Through the reasonable arrangement of the above fire protection system, the fire protection system occupies a small space inside the cabinet 1, and the temperature sensor 82, the smoke sensor 83 and the aerosol fire extinguishing device 84 are all arranged at a position relative to the electric box 62. When a fire occurs, the signal is detected and the fire extinguishing is started in the first time, which effectively enhances the fire protection effect and improves the fire safety level.

[0045] Specifically, the temperature sensor 82 and the smoke sensor 83 are both arranged above the electrical box 62, that is, in the battery compartment. When the temperature rises or smoke appears, they immediately transmit a signal to the fire host in the fire control box 81. After the signal transmission is completed, the fire host controls the aerosol fire extinguishing device 84 to quickly open and activates the sound and light alarm 85 to alarm. Since the aerosol fire extinguishing device 84 is located on the compartment door 11 and is directly opposite to the electrical box 62, after the aerosol fire extinguishing device 84 is turned on, the fire extinguishing agent can quickly move upward and then extinguish the fire in the electrical box 62, achieving a good fire extinguishing effect.

[0046] In one embodiment, Figure 2 and Figure 3 As shown, in order to facilitate opening and closing of the compartment door 11 during maintenance, the compartment door 11 includes a left compartment door 111 and a right compartment door 112. During maintenance, the operator can open the left compartment door 111 and the right compartment door 112 in opposite directions to provide an operating space for the operator's subsequent maintenance.

[0047] Further, such as Figure 2 As shown, a first air permeable net 91 is provided on the left door 111, and a second air permeable net 92 is provided on the right door 112. The first air permeable net 91 is arranged opposite to the position of the energy storage inverter 2, and the second air permeable net 92 is arranged opposite to the position of the liquid cooling system 4, thereby increasing the heat dissipation channel in the cabinet 1, ensuring smooth ventilation in the cabinet 1, and further enhancing the heat dissipation effect.

[0048] Further, such as Figure 2 As shown, a sound and light alarm 85 and an indicator light 93 are arranged side by side below the second air permeable net 92, and a human-machine interface 94 and an emergency stop device 95 are arranged side by side below the sound and light alarm 85 and the indicator light 93. When a fire occurs, the emergency stop device 95 can be activated to immediately stop the operation of the energy storage system in the cabinet 1, thereby preventing the fire from spreading.

[0049] In one embodiment, Figure 5 As shown, in order to increase the aesthetics of the cabinet 1 , a decorative piece 12 is provided on the cabinet 1 .

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
