[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0027] Please refer to Figures 1 to 3 The utility model relates to an energy storage box, which includes a box body 1, wherein a accommodating cavity 11 is arranged in the box body 1, and a wire hole 12 and a water injection hole 13 are provided on the box body 1, wherein the wire hole 12 is connected with the accommodating cavity 11, and the water injection hole 13 is located at the top of the box body 1, and further includes a water injection pipe 2, wherein the water injection pipe 2 is arranged in the water injection hole 13, wherein one end of the water injection pipe 2 is connected with the accommodating cavity 11, and the other end is connected with a fire-fighting pipe outside the box body.

[0028] From the above description, it can be seen that the beneficial effect of the utility model is that: a wire hole 12 and a water injection hole 13 are set on the box body 1, wherein the wire hole 12 is connected to the accommodating chamber 11 inside the box body 1, and the wire hole 12 is used for passing wires and other equipment, so as to electrically connect the battery and other equipment in the accommodating chamber 11 to an external power source or energy source (such as a power grid, power generation equipment, etc.). Similarly, the water injection hole 13 located at the top of the box body 1 is also connected to the accommodating chamber 11 in the box body 1, and a water injection pipe 2 is set in the water injection hole 13, so that one end of the water injection pipe 2 is connected to the accommodating chamber 11, and the other end is connected to the fire-fighting pipe outside the box body 1. In actual use, if the battery in the energy storage box catches fire, the water from the external fire-fighting pipe can be injected into the energy storage box from top to bottom through the water injection pipe 2 in the top water injection hole 13, so as to quickly extinguish the fire in the energy storage box, reduce the situation where the fire spreads to other equipment, and effectively avoid the spread of fire.

[0029] Furthermore, in the energy storage box described in the utility model, the box body 1 is provided with a first mounting hole 14 , the first mounting hole 14 is communicated with the accommodating cavity 11 , and a wind cover 3 is provided in the first mounting hole 14 .

[0030] In practical applications, the wind hood can be connected to the corresponding equipment in the energy storage box, such as the energy storage inverter, so that the energy storage inverter can be cooled through the wind hood, so as to discharge the heat generated by the corresponding equipment in time, thereby avoiding transmission failures caused by excessive equipment temperature, and further improving the safety of the energy storage box.

[0031] Furthermore, in the energy storage box described in the utility model, the box body 1 is provided with a second mounting hole 15 , the second mounting hole 15 is communicated with the accommodating cavity 11 , and a fire-fighting pressure relief valve 4 is provided in the second mounting hole 15 .

[0032] It can be seen from the above description that by setting a fire pressure relief valve 4 in the energy storage box, overpressure can be effectively prevented. When overpressure occurs, the fire pressure relief valve 4 can respond quickly, automatically open the pressure relief channel, and safely discharge excess gas into the external environment, thereby preventing the internal pressure from being too high and ensuring safe operation. In addition, the provision of a fire pressure relief valve 4 can help ensure the fire extinguishing effect. When a fire occurs inside the energy storage box, a fire extinguishing agent may be sprayed to extinguish the fire. If the internal pressure is too high, it will affect the spraying effect of the fire extinguishing agent. By opening the fire pressure relief valve 4, the internal pressure of the system can be balanced to ensure that the fire extinguishing agent can be smoothly and evenly sprayed into the fire area, thereby improving the fire extinguishing efficiency. In actual applications, the fire pressure relief valve can be used to prevent the air pressure released at the moment of battery failure.

[0033] Furthermore, in the energy storage box described in the utility model, an air inlet hole 16 and an air outlet hole 17 are provided on the box body 1 , and both the air inlet hole 16 and the air outlet hole 17 are communicated with the accommodating cavity 11 .

[0034] As can be seen from the above description, an air inlet 16 (i.e., an air-conditioning air inlet) and an air outlet 17 (i.e., an air-conditioning air outlet) connected to the accommodating cavity 11 are provided on the box body 1. When in use, the air inlet 16 allows external air to enter the air-conditioning inside the energy storage box. After being processed by the air-conditioning (such as cooling, dehumidification, etc.), the battery and other components inside the energy storage box are cooled and dissipated. Thereafter, the air that has absorbed the heat is discharged out of the box body 1 through the air outlet 17, thereby effectively dissipating the heat of the battery and other components and reducing the situation where the temperature of the battery and other equipment is too high.

[0035] Furthermore, in the energy storage box of the utility model, the box body 1 is provided with a third mounting hole 18, the third mounting hole 18 is connected to the accommodating cavity 11, and an auxiliary pressure relief member 6 is provided in the third mounting hole 18. It should be noted that the auxiliary pressure relief member 6 functions like a balancing valve, and is used to balance the air pressure in the bin at high and low temperatures.

[0036] Furthermore, in the energy storage box of the utility model, the box body 1 is also provided with a plurality of grooves 19 arranged side by side, and the grooves 19 extend along the vertical height direction of the box body 1. It should be noted that the plurality of grooves are provided on the box body to facilitate injection molding of the box body and save materials.

[0037] Furthermore, the energy storage box described in the present invention further includes a cabinet door 5 , which is disposed on the box body 1 , and the cabinet door 5 is rotatably connected to the box body 1 .

[0038] It can be seen from the above description that the rotatably connected cabinet door 5 is provided to facilitate corresponding operations on the equipment in the energy storage box, such as installing, disassembling and replacing the equipment in the energy storage box.

[0039] Furthermore, in the energy storage box described in the utility model, the box body 1 includes a top plate, a bottom plate and a side plate, the top plate is arranged at the upper end of the side plate, the bottom plate is arranged at the lower end of the side plate, and the top plate, the bottom plate and the side plate together form the accommodating cavity 11, wherein the water injection hole 13 is opened on the top plate, and the wire hole 12 is opened on the side plate.

[0040] It can be seen from the above description that by setting the water injection hole 13 on the top plate, when a fire occurs, water from the external fire-fighting pipe can be injected into the energy storage box from top to bottom through the water injection pipe 2 in the top water injection hole 13, so as to quickly extinguish the energy storage box, reduce the spread of fire to other equipment, and effectively avoid the spread of fire.

[0041] Furthermore, in the energy storage box described in the present invention, the box body 1 is made of UHPC material.

[0042] Furthermore, in the energy storage box described in the present utility model, the box body 1 is prepared by integral molding.

[0043] In practical applications, the material of the box 1 is UHPC (Ultra-High Performance Concrete) material / composite material. UHPC composite material is a cement-based composite material with extremely high strength, high toughness and excellent durability. When producing the box 1 made of UHPC material, the box 1 is cast in one piece, so that the box 1 has a good sealing and waterproof effect, that is, it has obvious advantages in the sealing and waterproofing of the cabin.

When preparing the energy storage box, the above-mentioned components can be directly installed on the prepared box body 1 to quickly assemble the energy storage box. In addition, it should be noted that a drain valve can be set at the corresponding position of the energy storage box, such as the bottom of the energy storage box, so that the water flowing into the energy storage box can be discharged from the energy storage box at the corresponding time.

[0047] In summary, the energy storage box provided by the utility model: (1) The box body is cast in one piece, which has obvious advantages in terms of cabin sealing and waterproofing.
