[0001] This utility model relates to the field of fire-fighting sandbox technology, specifically a fire-fighting sandbox for battery thermal runaway in a battery swapping station. Background Technology

[0002] New energy vehicles are generally powered by charging. However, due to issues such as long charging times and uneven distribution of charging stations, new energy vehicle users still face range anxiety and charging anxiety. Battery swapping, as a more efficient way to replenish energy, has many advantages. A battery swapping station is an energy station that centrally stores and charges batteries. It provides battery replacement services for electric vehicles by simply swapping a fully charged battery from the charging rack into the car to meet driving needs.

[0003] Currently, battery thermal runaway refers to the uncontrolled chemical reaction process inside the battery, which leads to an increase in battery temperature and may cause dangerous situations such as fire and explosion. Overcharging or discharging of the battery or puncture damage can cause thermal runaway. When a battery experiences thermal runaway, in order to prevent the thermal runaway battery from affecting other batteries on the charging rack, it needs to be removed from the charging rack and moved to a suitable external location for treatment. To facilitate the reception and movement of thermal runaway batteries, a battery thermal runaway fire-fighting sandbox for battery swapping stations is proposed. Utility Model Content

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the battery thermal runaway fire-fighting sandbox in this embodiment of the battery swapping station includes a sandbox body 1, which has a certain structural strength. A cavity 2 is provided inside the sandbox body 1 for placing the battery that has experienced thermal runaway. One end of the sandbox body 1 has a passage 3 for allowing the battery experiencing thermal runaway to move into the cavity 2. A rotating protective plate 4 is rotatably installed inside the passage 3 to protect the cavity 2. The rotating protective plate 4 can rotate to allow the passage 3 to be opened and closed. The interior is equipped with two U-shaped support plates 5. Each U-shaped support plate 5 has several guide wheels 6 installed inside via a rotating shaft. The surface of the guide wheels 6 extends above the U-shaped support plates 5. The U-shaped support plates 5 are used to support the battery. The setting of the guide wheels 6 effectively reduces the friction between the battery box surface and the U-shaped support plates 5, making it easier for the battery that has experienced thermal runaway to enter the cavity 2. The top of the sandbox body 1 is detachably equipped with a top cover 7. The top cover 7 can be removed to facilitate the use of dry powder fire extinguishers and fire sand to extinguish the fire inside the battery in the cavity 2.

[0021] Specifically, a fixed shaft 8 is installed inside the upper part of the port 3, and a connecting plate 9 is sleeved on the surface of the fixed shaft 8. A rotating protective plate 4 is installed at one end of the connecting plate 9. The rotating protective plate 4 is rotatably connected to the surface of the fixed shaft 8 through the connecting plate 9, so as to realize the rotation function of the rotating protective plate 4, and the rotating protective plate 4 can rotate in both directions.

[0022] Furthermore, the U-shaped support plate 5 is arranged at an angle from high to low from one side of the passage 3 to the other side, and several guide wheels 6 are installed at equal intervals inside the U-shaped support plate 5. The inclined arrangement of the U-shaped support plate 5 allows the battery to enter the cavity 2 without the need for additional thrust. The equal distribution of the guide wheels 6 ensures the smooth movement of the battery.

[0023] Furthermore, a connecting frame 10 is installed at the lower end of the top cover 7. The connecting frame 10 is sleeved on the upper part of the sandbox body 1. Two handles 11 are installed on the surface of the top cover 7. The setting of the connecting frame 10 ensures the stability of the top cover 7 installation and prevents the top cover 7 from accidentally falling off when the sandbox body 1 is moved. The setting of the handles 11 makes it easy to remove the top cover 7, which facilitates the addition of fire sand into the sandbox body 1 or the use of a dry powder fire extinguisher to handle the battery replacement.

[0024] Furthermore, notches are provided at both the front and rear of the bottom of the opening 3, and one end of each of the two U-shaped support plates 5 extends to the outside of the sandbox body 1 through the notches. The rotating protective plate 4 will not come into contact with the U-shaped support plate 5, and the rotating protective plate 4 will completely block the opening 3.

[0025] Furthermore, the bottom of the sandbox body 1 is equipped with four universal wheels 12 in a rectangular array. The universal wheels 12 have a locking function to prevent the sandbox body 1 from moving accidentally when the battery is inserted. The other end of the sandbox body 1 is equipped with a handle 13. The handle 13 is designed to make it easy to push and pull the sandbox body 1, so as to move the sandbox body 1 to a suitable position.

[0026] The usage method of this embodiment is as follows: When in use, the sandbox is placed in a designated position. When the battery swapping device inside the charging rack experiences thermal runaway, the robotic arm uses a battery swapping clamp to remove the battery that has experienced thermal runaway and places it into the cavity 2 through the port 3. During this process, the battery swapping device pushes against the rotating protective plate 4, and at the same time, the bottom of the battery swapping device that has experienced thermal runaway contacts the guide wheel 6 on the U-shaped support plate 5. Since the U-shaped support plate 5 is inclined, the battery swapping device enters the cavity 2 under the action of gravity. Then, the sandbox body 1 is moved to a suitable position using the handle 13, and the top cover 7 is removed using the handle 11. The battery that has experienced thermal runaway is buried using fire sand or sprayed with a dry powder fire extinguisher to effectively avoid affecting the other batteries.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
