Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery energy storage containers, in particular to an energy storage container. Background Art
[0002] Battery energy storage systems are widely used due to their ability to efficiently store and manage electrical energy. However, due to the chemical properties of batteries, particularly lithium-ion batteries, these systems are susceptible to thermal runaway due to factors such as overheating, short circuits, or mechanical damage. Thermal runaway can cause the internal temperature of the battery to rise rapidly, releasing flammable gases and even causing fires and explosions. These accidents not only damage the equipment but also pose a threat to personnel safety and the environment. Current energy storage containers primarily rely on gas and water fire extinguishing systems for fire protection. They lack ventilation within the container to dissipate heat and control temperature, nor do they provide effective smoke exhaust in the event of a fire or other emergency. Utility Model Content
[0003] The purpose of the utility model is to provide an energy storage container, by arranging air inlets and exhaust vents on the energy storage container body, so that the air in the energy storage container body can circulate, which is beneficial to heat dissipation, temperature control and smoke exhaust in the event of fire or other emergency situations.
[0004] To achieve the above objectives, the present invention provides an energy storage container, including an energy storage container body, a liquid fire extinguishing system and an energy storage PACK are arranged in the energy storage container body, a fire extinguishing device is arranged in the energy storage PACK, and the energy storage container body is also provided with an air inlet and an air exhaust port.
[0005] The air inlet is located on the side wall of the energy storage container body, and the air outlet is located on the top of the energy storage container body.
[0006] An exhaust pipe is installed on the energy storage container body at the exhaust port.
[0007] A rainproof cap is installed above the exhaust pipe.
[0008] The rainproof cap is a conical cover structure, and the rainproof cap is connected and fixed to the exhaust pipe through a support rod.
[0009] The exhaust pipe is a cylindrical tube structure, the rain cap is connected to the mounting ring through a support rod, and the mounting ring is fixed on the exhaust pipe.
[0010] The lower end of the exhaust pipe is a conical tube structure with a small upper part and a large lower part, and the upper end is a cylindrical tube structure. The rain cap is connected to the mounting ring through a support rod, and the mounting ring is fixed on the cylindrical tube structure.
[0011] A first flange is sealed and installed at the air outlet of the energy storage container body, a second flange is installed at the lower end of the exhaust pipe, and the second flange is installed on the first flange by bolts.
[0012] The inner circumference of the first flange is provided with a flange extending upward.
[0013] The energy storage container body is provided with a plurality of air exhaust vents, and the interior of the energy storage container body is partitioned according to the number of the air exhaust vents to form a plurality of compartments, and each compartment has at least one air inlet.
[0014] Compared with the prior art, the present invention has the following technical effects:
[0015] 1. The utility model provides air inlets and exhaust vents on the energy storage container body, thereby allowing air to circulate inside the energy storage container body, which is beneficial to heat dissipation, temperature control, and smoke exhaust in the event of fire or other emergencies.
[0016] 2. By installing an exhaust pipe at the exhaust vent, this utility model utilizes the chimney effect. Even without electrical power, the system can effectively expel hot air from the energy storage container through natural convection, thereby reducing the internal temperature. This passive cooling method not only saves energy but also ensures that the temperature inside the container will not rise rapidly in the event of a power system failure, reducing the risk of equipment failure or fire due to overheating.
[0017] The exhaust funnel guides flames into the interior, centrally controlling the fire and preventing it from spreading within the energy storage container. By funneling flames and high-temperature gases out of the funnel, damage to other equipment and structures within the container is minimized, improving the overall safety of the system. This function is crucial in preventing the spread of fire and significantly reduces its destructive power.
[0018] In the event of a power outage or system failure in the air intake and exhaust systems, the exhaust chimneys can still dissipate hot air from the container through the chimney effect, preventing heat accumulation. This emergency heat dissipation function provides an effective heat dissipation path at critical moments, avoiding secondary disasters caused by high temperatures and ensuring the safe operation of the energy storage container.
[0019] Because this patented solution relies on the natural chimney effect rather than an electrically driven mechanical device, system reliability is significantly improved. Even in the event of a power outage or mechanical failure, the system remains effective. This design significantly enhances the safety of the energy storage container firefighting system, ensuring continuous protection in all operating conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0030] Example 1:
[0031] See Figure 1-4 An energy storage container includes an energy storage container body 10, which is equipped with a liquid fire extinguishing system and an energy storage pack. The energy storage pack is equipped with a fire extinguishing device. The energy storage container body 10 is also provided with an air inlet 11 and an air outlet 12. The air inlet 11 and the air outlet 12 on the energy storage container body 10 allow air to circulate within the energy storage container body 10, facilitating heat dissipation, temperature control, and smoke exhaust in the event of a fire or other emergency.
[0032] Specifically, the air inlet 11 is located on the side wall of the energy storage container body 10 , and the air outlet 12 is located on the top of the energy storage container body 10 .
[0033] The air inlet 11 can be equipped with a fan as needed.
[0034] Example 2:
[0035] See also Figure 1-4 An exhaust pipe 20 is installed on the energy storage container body 10 at the exhaust port 12.
[0036] By installing an exhaust chimney 20 at the exhaust port 12 and utilizing the chimney effect, the system can effectively exhaust hot air from the energy storage container through natural convection, even without power, thereby reducing the internal temperature. This passive cooling method not only saves energy but also ensures that the temperature inside the container will not rise rapidly in the event of a power system failure, reducing the risk of equipment failure or fire due to overheating.
[0037] The exhaust chimney 20 guides flames into the interior, centrally controlling the fire and preventing it from spreading within the energy storage container. By centrally discharging flames and high-temperature gases through the exhaust chimney 20, damage to other equipment and structures within the container is reduced, improving the overall safety of the system. This function is crucial in preventing the spread of fire and significantly reduces its destructive power.
[0038] In the event of a power outage or system failure in the air intake and exhaust systems, the exhaust chimney 20 can still exhaust hot air from the container through the chimney effect, preventing heat accumulation. This emergency heat removal function provides an effective heat dissipation path at critical moments, avoiding secondary damage caused by high temperatures and ensuring the safe operation of the energy storage container.
[0039] Because this patented solution relies on the natural chimney effect rather than an electrically driven mechanical device, system reliability is significantly improved. Even in the event of a power outage or mechanical failure, the system remains effective. This design significantly enhances the safety of the energy storage container firefighting system, ensuring continuous protection in all operating conditions.
[0040] Example 3:
[0041] Based on the second embodiment, a rainproof cap 30 is installed above the exhaust pipe 20 .
[0042] See also Figure 1-3 The rain cap 30 is a conical cover structure, connected to the exhaust pipe 20 via support rods 31. Installing the rain cap 30 provides protection from rain when used outdoors. During installation, at least three support rods 31 are welded to the exhaust pipe 20 in a circular pattern. The rain cap 30 is welded to the tops of the three support rods 31.
[0043] In one of the solutions, the exhaust pipe 20 is a cylindrical tube structure, the rain cap 30 is connected to the mounting ring 32 through a support rod 31, and the mounting ring 32 is fixedly mounted on the exhaust pipe 20.
[0044] In another embodiment, the lower end of the exhaust pipe 20 is a conical tube structure that is smaller at the top and larger at the bottom, and the upper end is a cylindrical tube structure. The rain cap 30 is connected to the mounting ring 32 through a support rod 31, and the mounting ring 32 is fixed on the cylindrical tube structure.
[0045] In the above embodiment, the mounting ring 32 is a circular ring or a clamping hoop. In the case of a circular ring, screws are radially screwed onto the ring, which abut against the exhaust pipe 20, thereby securing the mounting ring 32 to the exhaust pipe 20. In the case of a clamping hoop, the mounting ring 32 is tightly secured to the exhaust pipe 20 by bolts on the clamping hoop.
[0046] Of course, the rainproof cap 30 may also adopt the rainproof wind cap structure disclosed in CN220017406U.
[0047] Example 4:
[0048] On the basis of Example 2 or Example 3, in order to facilitate transportation, see Figure 3 The energy storage container's main body 10 has a first flange 13 sealed against the exhaust port 12. A second flange 21 is mounted at the lower end of the exhaust pipe 20, bolted to the first flange 13. During transportation, the exhaust pipe 20 is removed. Once the energy storage container is installed, the second flange 21 is bolted to the first flange 13. The first flange 13 is welded to the main body 10, and a sealing ring or sealant is applied between the first and second flanges 13, ensuring waterproofing.
[0049] For further information, see Figure 3 To enhance the watertight seal, an upwardly extending flange 131 is provided on the inner circumference of the first flange 13. The flange 131 provides a waterproof effect. When the lower end of the exhaust pipe 20 is inserted into the flange 131, the flange 131 extends upward for a certain height. This prevents rainwater from entering the energy storage container body 10 even if the sealing ring or sealant is damaged.
[0050] Embodiment 5:
[0051] On the basis of Example 2, Example 3 or Example 4, see Figure 4 The top of the energy storage container body 10 is equipped with multiple exhaust vents 12, each of which is equipped with an exhaust pipe 20. The interior of the energy storage container body 10 is partitioned into multiple compartments based on the number of exhaust vents 12, each of which has at least one air inlet 11. This structure achieves regional ventilation and cooling. The interior of the energy storage container body 10 is divided by insulation material, so if thermal runaway occurs in one compartment, it is unlikely to spread to the entire energy storage container body 10.
[0052] The working principle or action process of the utility model is as follows:
[0053] See also Figure 3 During transportation, remove the connecting bolts between the second flange 21 of the exhaust pipe 20 and the first flange 13 on the energy storage container body 10 and remove the exhaust pipe 20.
[0054] When the energy storage container is installed outdoors, a rainproof cap 30 is installed on the top of the exhaust chimney 20 .
[0055] This utility model utilizes the chimney effect. Even without electrical power, the system effectively exhausts hot air from the energy storage container through natural convection, thereby reducing the internal temperature. This passive cooling method not only saves energy but also prevents a rapid rise in temperature within the container in the event of a power failure, reducing the risk of equipment failure or fire due to overheating.
