[0020] The following is a further detailed description of the specific implementation manners of the present utility model, such as the shapes, structures of the components involved, the mutual positions and connection relationships between the various parts, the functions of the various parts, and the working principles, etc., with reference to the drawings:
[0021] As shown in the attached Figure 1 and attached Figure 2As shown in the figure, the utility model relates to a fire-fighting mechanism for thermal runaway batteries in a marine power exchange station, which includes a fire-extinguishing pool 1 and a fire-fighting cage 2. The fire-fighting cage 2 is located above the fire-extinguishing pool 1. A battery bracket 3 is arranged inside the fire-fighting cage 2. The upper part of the battery bracket 3 is connected to the upper part of the fire-fighting cage 2 through a lifting component 4, and the lifting component 4 is connected to a control component 7. The above structure proposes an improved technical solution for the deficiencies in the prior art. When setting up the structure, the fire-extinguishing pool 1 and the fire-fighting cage 2 are manufactured separately. The fire-fighting cage 2 is located above the fire-extinguishing pool 1 and the two are fixedly connected. The upper part of the fire-extinguishing pool 1 is an open structure, which is convenient for the battery bracket 3 to enter and exit the fire-extinguishing pool 1. The fire-extinguishing pool 1 is filled with cooling water. A battery bracket 3 is arranged inside the fire-fighting cage 2. The thermal runaway battery that needs fire-fighting treatment can be placed in the battery bracket 3. The upper part of the battery bracket 3 is connected to the upper part of the fire-fighting cage 2 through a lifting component 4, and the lifting component 4 is connected to the control component 7. The control component can control the lifting of the lifting component 4. When the control component 7 controls the lifting component 4 to rise, the lifting component 4 drives the battery bracket 3 to move upward and is located above the fire-extinguishing pool 1. When the control component 7 controls the lifting component 4 to descend, the lifting component 4 drives the battery bracket 3 to move downward, and the battery bracket 3 enters the fire-extinguishing pool 1, that is, the thermal runaway battery placed on the battery bracket 3 enters the cooling water to achieve fire-fighting treatment. After the fire-fighting treatment is completed, the control component 7 controls the lifting component 4 to rise again, and the lifting component 4 drives the battery bracket 3 to leave the fire-extinguishing pool 1, and the battery after the fire-fighting treatment can be processed subsequently. The above structure has a simple overall fire-fighting mechanism, few components, no overly complex structure, and good control reliability. The entire mechanism is based on the fire-extinguishing pool 1 and the fire-fighting cage 3, and the relevant components are arranged inside it, without the need for an overly large layout space. When arranging the fire-fighting mechanism, it can be arranged inside the power exchange station, close to the battery, which is convenient for timely fire-fighting disposal when the battery has a thermal runaway problem and ensures the overall safety of the thermal power station. The fire-fighting mechanism for thermal runaway batteries in the marine power exchange station described in the utility model has a simple structure, can conveniently and reliably achieve the fire-fighting treatment of thermal runaway batteries, and the overall structure is based on the fire-extinguishing pool and the fire-fighting cage, without the need for an overly large layout space and complex structure. The lifting component and the battery that needs fire-fighting treatment are both located inside the fire-fighting cage, thus realizing the compactness and simplification of the structure and reducing the cost.
[0022] A temperature sensor is arranged inside the fire-extinguishing pool 1. The temperature sensor is connected to the control component. The fire-extinguishing pool 1 is connected to a water inlet pipeline 5 and a water outlet pipeline 6. The above structure, the temperature sensor monitors the temperature of the cooling water in the fire-extinguishing pool in real time and feeds it back to the control component. When the thermal runaway battery enters the fire-extinguishing pool for cooling, when the actual water temperature exceeds the set temperature, after the temperature sensor feeds back the temperature to the control component, the control component 7 controls the inlet water pump 12 and the outlet water pump 13 to start.
[0023] The fire extinguishing pool 1 contains cooling water. An inlet pump 12 is provided on the inlet pipe 5, and an outlet pump 13 is provided on the outlet pipe 6. The inlet pump 12 and the outlet pump 13 are respectively connected to the control component. In the above structure, when the temperature of the cooling water in the fire extinguishing pool 1 is too high, the temperature sensor of the fire extinguishing pool feeds back a signal to the control component 7, and the control component 7 controls the inlet pump 12 and the outlet pump 13 to circulate and replace the cooling water in the fire extinguishing pool 1, that is, high-temperature water is discharged and low-temperature water is entered.
[0024] The battery of the marine battery swap station is provided with a thermal runaway alarm component, which includes a temperature sensor and a buzzer. In the above structure, when the battery does not alarm due to thermal runaway, the battery is stored normally. When the battery has thermal runaway, the actual temperature of the battery exceeds the set temperature, and the buzzer alarms, then the trapezoidal on-site personnel need to carry out fire-fighting treatment on the battery. The on-site personnel transfer the battery to the battery bracket, and then control the battery bracket to move downward, enter the cooling water in the fire extinguishing pool for cooling treatment, and eliminate the hidden dangers of combustion or explosion caused by the thermal runaway battery.
[0025] The lifting component 4 is a scissor lift. The scissor lift is a mature product in the prior art, and the utility model is directly quoted, and the purpose of the lifting component is to achieve lifting.
[0026] The battery bracket 3 is a square frame structure, and a guide wheel 8 is arranged on the side of the battery bracket 3, and the guide wheel is close to the inner side of the fire cage frame 2. In the above structure, the guide wheels are arranged on both sides of the battery bracket to ensure that the battery bracket can be reliably and stably lifted and lowered along the fire cage frame 2. After the battery bracket enters the fire extinguishing pool, the guide wheel 8 of the battery bracket 3 moves down along the inner wall of the fire extinguishing pool.
[0027] The ship-based battery swap station includes a constant temperature warehouse 9, in which a plurality of battery racks 10 are placed, and a water extinguishing pool 1 and a fire cage rack 2 are both located in the constant temperature warehouse 9. A stacker 11 is also placed in the constant temperature warehouse 9. With the above structure, the battery swap station includes a plurality of batteries for battery replacement. The constant temperature warehouse is in a constant temperature state, ensuring that the battery is in an optimal temperature environment and reducing the probability of thermal runaway due to excessive temperature. With the above structure, the battery swap station is arranged on a ship. The stacker 11 is used to conveniently move the battery in thermal runaway in the constant temperature warehouse 9 to the location of the fire fighting agency.
[0028] For the fire-fighting mechanism for thermal runaway batteries of the marine power exchange station described in the present utility model, during the structural design, a fire-extinguishing pool 1 and a fire-fighting cage 2 are respectively fabricated. The fire-fighting cage 2 is located above the fire-extinguishing pool 1 and the two are fixedly connected. The upper part of the fire-extinguishing pool 1 is an open structure to facilitate the battery carrier 3 to enter and exit the fire-extinguishing pool 1. The fire-extinguishing pool 1 is filled with cooling water. The battery carrier 3 is arranged inside the fire-fighting cage 2, and the thermal runaway batteries that need fire-fighting treatment can be placed inside the battery carrier 3. The upper part of the battery carrier 3 is connected to the upper part of the fire-fighting cage 2 through a lifting component 4, and the lifting component 4 is connected to a control component 7. The control component can control the lifting of the lifting component 4. When the control component 7 controls the lifting component 4 to rise, the lifting component 4 drives the battery carrier 3 to move upward and be located above the fire-extinguishing pool 1. When the control component 7 controls the lifting component 4 to descend, the lifting component 4 drives the battery carrier 3 to move downward, and the battery carrier 3 enters the fire-extinguishing pool 1, that is, the thermal runaway batteries placed on the battery carrier 3 enter the cooling water to achieve fire-fighting treatment. After the fire-fighting treatment is completed, the control component 7 controls the lifting component 4 to rise again, and the lifting component 4 drives the battery carrier 3 to leave the fire-extinguishing pool 1, and subsequent treatment can be carried out on the batteries after fire-fighting treatment. For the above structure, the entire fire-fighting mechanism has a simple structure, few components, no overly complex structure, and good operation reliability. Moreover, the entire fire-fighting mechanism is based on the fire-extinguishing pool 1 and the fire-fighting cage 3, and the relevant components are arranged inside it, without the need for an overly large layout space. When the fire-fighting mechanism is arranged, it can be arranged inside the power exchange station, close to the batteries, so as to facilitate timely fire-fighting disposal when the batteries have thermal runaway problems and ensure the overall safety of the thermal power station.
