DETAILED DESCRIPTION

[0025] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] Embodiment 1: An air-cooled battery storage box, see Figure 1-Figure 3As shown, it includes a support base 1, an energy storage box 2, a first protective door 201, a second protective door 202, a placement rack 3, a battery compartment 4, an EMS device 5, a main controller 6, an inverter PCS7 and a ventilation component. The energy storage box 2 is installed on the support base 1 by bolt connection. The first protective door 201 and the second protective door 202 are rotatably arranged on both sides of the energy storage box 2. A plurality of placement racks 3 are installed in the energy storage box 2. The battery compartment 4 for energy storage and power supply is installed on the placement rack 3 by bolt connection. The EMS device 5 is installed in the energy storage box 2 by bolt connection. The EMS device 5 is electrically connected to the battery compartment 4. The main controller 6 is installed on the EMS device 5 by bolt connection. Controller 6, EMS device 5 is electrically connected to main controller 6, converter PCS7 is installed in energy storage box 2 by bolt connection, converter PCS7 is electrically connected to EMS device 5, ventilation assembly for ventilation is provided on energy storage box 2, and also includes first fixed block 13, fire detection tube 14, second fixed block 15 and gas cylinder 16, multiple first fixed blocks 13 are installed on the top of energy storage box 2 by welding, multiple first fixed blocks 13 are commonly penetrated by fire detection tube 14, second fixed block 15 is installed on the side of placement rack 3 by welding, gas cylinder 16 is installed on second fixed block 15 by bolt connection, fire detection tube 14 is connected and communicated with gas cylinder 16.

[0027] See also Figure 2 and Figure 3 As shown, the ventilation assembly includes a ventilation box 9 installed on the first protective door 201 by bolt connection, and two upper and lower fans 10 are installed in the ventilation box 9 by bolt connection. A ventilation net 8 is installed in the gap between the energy storage box 2 and the placement rack 3 by bolt connection, and a plurality of first air outlets 11 are opened on the rear side of the placement rack 3, and a plurality of second air outlets 12 are opened on the rear side of the energy storage box 2.

[0028] When the battery compartment 4 generates a large amount of heat during operation and the energy storage box 2 needs to be cooled, the fan 10 is started to draw outside air into the ventilation box 9 and transport it to the energy storage box 2. When the cold air enters the energy storage box 2, it passes through the ventilation net 8 into the storage racks 3, takes away the heat of the battery compartment 4 on the storage racks 3 and flows out from the first air outlet 11, and then the hot air is discharged from the energy storage box 2 from the second air outlet 12; when the electrical appliances in the energy storage box 2 burn, the temperature in the energy storage box 2 rises to a certain temperature, which will cause the fire detection tube 14 to rupture, so that the inert gas and fire extinguishing material in the gas cylinder 16 can leak, so as to put out the fire in time and avoid explosion and larger fire.

[0029] Example 2: Based on Example 1, refer to Figure 4As shown, it also includes a smoke detection alarm 17 installed on the top of the energy storage box 2 by bolt connection, a third fixing block 19 is installed on the outer side of the energy storage box 2 by welding, a warning light 20 is installed on the third fixing block 19 by bolt connection, and a connecting line 18 is connected between the warning light 20 and the smoke detection alarm 17.

[0030] When the temperature of the electrical appliances in the energy storage box 2 is too high and combustion occurs to produce smoke, the smoke detection alarm 17 will detect the smoke produced by the combustion, and at this time transmit the signal to the warning light 20 through the connecting line 18, so that the warning light 20 emits a flashing warning signal to prompt the staff to deal with it in time.

[0031] See also Figure 5 As shown, it also includes a cold water drain 22 installed in the ventilation box 9 by means of bolt connection, and a dustproof net 21 is installed on the cold water drain 22 by means of bolt connection. The dustproof net 21 is located on the side of the cold water drain 22 away from the fan 10.

[0032] When the fan 10 draws outside air into the ventilation box 9, the dustproof net 21 will filter the dust impurities in the inhaled air, and cool the air through the cold water drain 22. The cooled air is transported to the energy storage box 2 for cooling, so as to achieve a better cooling effect.

[0033] See also Figure 6 and Figure 7 As shown, it also includes two guide blocks 26 installed on the inner side of the second protective door 202, and a wedge-shaped card plate 27 is slidably arranged on the two guide blocks 26. The wedge-shaped card plate 27 slides laterally along the guide blocks 26, and an elastic member 28 is wound around the wedge-shaped card plate 27. A fourth fixed block 25 for clamping the wedge-shaped card plate 27 is installed on the inner side of the first protective door 201 by bolt connection. The elastic member 28 pushes the wedge-shaped card plate 27 to clamp with the fourth fixed block 25. A pull block 23 is fixedly connected to the wedge-shaped card plate 27 by welding. The pull block 23 penetrates to the outside of the second protective door 202. A wedge block 24 is installed on the first protective door 201 by bolt connection, and the wedge block 24 cooperates with the wedge-shaped card plate 27.

[0034] When the energy storage box 2 needs to be closed, the first protective door 201 is first rotated and closed, and then the second protective door 202 is rotated and closed. At this time, the second protective door 202 drives the wedge-shaped card plate 27 to contact the wedge block 24 on the first protective door 201, so that the wedge block 24 pushes the wedge card plate 27 to slide along the side of the guide block 26 away from the first protective door 201. At this time, the elastic member 28 is compressed and deformed by force. When the wedge card plate 27 is flush with the fourth fixing block 25, the elastic member 28 loses the force and returns to its original state, thereby pushing the wedge card plate 27 to slide back to the original state. The wedge-shaped card plate 27 is positioned so that it is engaged with the fourth fixed block 25, so that the first protective door 201 and the second protective door 202 are mutually restrained and locked, so that the first protective door 201 and the second protective door 202 will not be easily opened; when the first protective door 201 and the second protective door 202 need to be opened, the pull block 23 is pulled to slide to the side away from the first protective door 201, so that the pull block 23 drives the wedge-shaped card plate 27 to disengage from the engaging limit with the fourth fixed block 25, and the first protective door 201 and the second protective door 202 can be pulled to rotate and open.

[0035] See also Figure 4 and Figure 7 As shown, a protective cover 29 is sleeved on the warning light 20, and a buffer pad 30 is installed on the side of the pull block 23 close to the first protective door 201 by bonding.

[0036] The protective cover 29 is used to protect the warning light 20 to prevent the warning light 20 from being damaged by being bumped; when the elastic member 28 pushes the wedge-shaped clamping plate 27 to reset, the buffer pad 30 can buffer the force of the pull block 23 hitting the second protective door 202 to prevent the pull block 23 from being damaged.
