[0027] A plurality of sensors 103 are provided in the battery compartment 3, and the sensors 103 are electrically connected to the control unit. The sensors 103 may be existing sensors for monitoring whether the battery is in thermal runaway, such as temperature sensors, image sensors and light sensors.

The control unit can use existing or commonly used fixed control equipment in the energy storage power station, such as PLC.

[0030] Two entry holes 203 are provided in the fixing seat 201, and the two entry holes 203 are respectively connected to the two parts of the water tank 202 separated by the support plate 205, and the entry holes 203 are communicated with the water tank 202; the bottom surface of the entry hole 203 is an inclined surface, and the inclined surface makes it easier for the fallen battery 4 to slide into the water tank 202; the entry hole 203 is located below the entrance and exit of the battery compartment 3; A water inlet seat 204 is provided on one side of the fixing seat 201, and a water inlet pipe 206 is provided on the water inlet seat 204, which is connected to the water tank 202; the water inlet pipe 206 is connected to an external water source, which is preferably an ice water source, and is connected to a solenoid valve, which is electrically connected to the control unit.

[0033] During use, when the control unit determines that the corresponding battery has thermal runaway, it controls the ejection mechanism 7 to eject the corresponding battery, and at the same time opens the solenoid valve of the water inlet pipe 206, so that water enters the water tank 202 through the water inlet pipe 206, and the ejected battery 4 falls into the entry hole 203 below, and then slides into the interior of the water tank 202 under the influence of the slope. The water can only cool the battery 4 and slow down the speed of thermal runaway of the battery 4. Then the battery 4 will be flushed into the processing box 209 by the water. The processing box 209 contains more water, which can completely submerge the battery 4 and stay away from the box body 1, so that the battery 4 with thermal runaway can be processed in time to avoid affecting other batteries 4 and avoid the battery 4 with thermal runaway from having adverse effects on the surrounding environment.

[0034] In a further embodiment, when a plurality of boxes 1 are provided, the boxes 1 are arranged in a row, and the inlets and outlets of the battery compartments 3 face the same direction; a fixing seat 201 is provided at the bottom of each box 1; The water inlet seat 204 and the processing box 209 are located at the two ends of the box set.

[0037] Embodiment 3: In order to facilitate the ejection of the battery 4, Figure 5As shown, a guide plate 301 is provided at the bottom of the inner wall of the battery compartment 3, and the battery 4 is located on the top of the guide plate 301; the guide plate 301 is used to facilitate the sliding of the battery 4, and a roller can be rotatably provided on the top of the guide plate 301 to further facilitate the sliding of the battery 4.

[0038] A slope 302 is provided at the bottom of the battery compartment 3 entrance to facilitate the battery 4 to slide down from the battery compartment 3 entrance after being ejected; The entrance and exit of the battery compartment 3 is provided with a first cover plate 303, and a slit 304 is provided in the first cover plate 303; The cut 304 can refer to the V-cut line, or cut through directly, leaving a small amount of uncut part in the cut 304. After the force is applied, the first cover plate 303 can be directly broken along the cut 304. The bottom surface of the first cover plate 303 is only in contact with the bottom surface of the inner wall of the battery compartment 3, the slit 304 is in an inverted U shape, and the size of the slit 304 is larger than the size of the edge of the end surface of the battery 4; When in use, the ejected battery 4 hits the first cover plate 303 , and then the first cover plate 303 is broken along the slit 304 by the impact, and then the battery 4 continues to fly out and completes the ejection, and is usually protected by the first cover plate 303 .

[0039] In a further embodiment, Fig.12 As shown, other identical structures are not repeated here. The entrance and exit of the battery compartment 3 is provided with a second cover plate 305, and the top of the second cover plate 305 is provided with a first rotating shaft 306.

[0040] When in use, the ejected battery 4 hits the second cover plate 305. The second cover plate 305 rotates with the first rotating shaft 306 upon being hit, and no longer blocks the battery 4. The battery 4 continues to fly out and is ejected. Normally, the battery 4 is protected by the second cover plate 305. The second cover plate 305 in this manner can be used repeatedly.

[0041] Embodiment 4: like Figure 6 , 7 As shown in , 8 and 11, the inner wall of the battery compartment 3 is provided with a guide rail 5, and the guide rail 5 is used to connect and guide the movement of the battery 4; The guide rail 5 includes a track 501 arranged on the inner wall of the battery compartment 3, and a guide groove 504 is provided on the side of the track 501 close to the battery 4, and a sliding rod 502 is slidably connected in the guide groove 504, and the side of the sliding rod 502 away from the track 501 is close to the battery 4; the connection between the sliding rod 502 and the track 501 is smooth, so that the sliding rod 502 can slide smoothly along the track 501, and preferably, a plurality of rolling balls are provided in the track 501, and the rolling balls are in contact with the sliding rod 502.

[0042] A limit strip 505 is provided on the inner wall of the guide groove 504 near the edge of the battery 4. The limit strip 505 extends to the inside of the sliding rod 502 and is slidably connected to the sliding rod 502. The limit strip 505 is used to limit the position of the sliding rod 502, and the connection surface with the sliding rod 502 is smooth.

[0043] A fixed shaft 506 is provided on one side of the sliding rod 502 close to the battery 4. The fixed shaft 506 is located at one end of the sliding rod 502 close to the entrance and exit of the battery compartment 3. The fixed shaft 506 is rotatably connected to a rotating drum 507, which is located on the end surface of the battery 4. The rotating drum 507 blocks the battery 4 to prevent the battery 4 from sliding out. Preferably, the top of the battery 4 is close to the top wall of the battery compartment 3 .

[0044] The inner wall of the guide groove 504 is provided with a slide groove 508, and the sliding rod 502 is provided with a slider 509, and the slider 509 is located inside the slide groove 508; the position of the sliding rod 502 is limited by the slider 509 and the slide groove 508 to prevent the sliding rod 502 from sliding out directly when the battery is ejected.

[0045] A positioner 503 is provided at one end of the track 501 away from the entrance and exit of the battery compartment 3; when the sliding rod 502 is located at the innermost side of the battery compartment 3, the positioner 503 is used to limit the sliding of the sliding rod 502; The positioner 503 includes a fixing sleeve 531 fixedly connected to the track 501, a spring 532 is arranged inside the fixing sleeve 531, a positioning groove 534 is arranged on the side of the sliding rod 502, and a limiting ball 533 is arranged on the spring 532, and the limiting ball 533 extends to the inside of the positioning groove 534; the positioning groove 534 is a circular groove; When the sliding rod 502 is located at the innermost side of the battery compartment 3, the limiting ball 533 is always located inside the positioning groove 534, so that the sliding rod 502 cannot move at will, thereby ensuring that the battery 4 will not move at will. When subjected to a large force, the force will be affected by the circular groove and the spherical surface of the limiting ball 533, and the force will produce a component force to offset the force given by the spring 532, so that the limiting ball 533 is away from the circular groove. At this time, the sliding rod 502 can slide normally.

[0046] When in use, the ejection mechanism 7 ejects the battery 4. At this time, a large thrust is generated to directly push the battery 4 out. At this time, the battery 4 will sequentially drive the rotating drum 507, the fixed shaft 506 and the sliding rod 502 to slide. When sliding out, the battery 4 is affected by the rotating drum 507 and cannot fly out directly. After the battery 4 is ejected and slides to the end, it is away from the battery compartment 3. Fig.11 As shown, the battery 4 cannot fly out, but slides downward under the action of gravity and finally falls into the entry hole 203, so that the battery 4 with thermal runaway can be handled easily and the battery 4 can be prevented from flying too far and affecting the surrounding environment.

[0047] Embodiment 5: like Figure 6 and 9 As shown, a connecting mechanism 6 is provided between the battery 4 and the isolation block 102, and the connecting mechanism 6 is used to connect the circuit; The connecting mechanism 6 comprises a connecting sleeve 601 fixedly connected to the isolation block 102, and an electric socket 602 is provided in the isolation block 102; A baffle 603 is provided on one side of the connecting sleeve 601 close to the battery 4, and the top of the baffle 603 is rotatably connected to the connecting sleeve 601 via a second rotating shaft 604; A limiting groove 605 is provided at the bottom of the inner wall of the connecting sleeve 601; The battery 4 is provided with an electrical connector 606, which extends to the interior of the connecting sleeve 601.

The electrical connector 606 and the electrical socket 602 preferably adopt a connecting piece contact type electrical connection method, or a material connection plug plug-in type connection method to ensure that they are not locked after connection.

[0048] During use, when the battery 4 is ejected, the power connector 606 is separated from the power socket 602. At this time, the baffle 603 is not affected by the power connector 606. Under the action of gravity, the baffle 603 rotates around the second rotating shaft 604 until the bottom end of the baffle 603 rotates to the limit groove 605. At this time, the baffle 603 can cover the power socket 602, thereby avoiding the influence of fire sources on the power socket 602, thereby ensuring the stability of the circuit.

[0049] In a further embodiment, Figure 6 and 10 As shown, the ejection mechanism 7 includes a pad 701 fixedly connected to the battery 4; The isolation block 102 is provided with a protective sleeve 702, a cavity is provided in the protective sleeve 702, a push plate 703 is provided on one side of the cavity close to the battery 4, and the push plate 703 is in contact with the cushion block 701; A compressed air bag 704 is provided in the cavity of the protective sleeve 702. The gas filled in the compressed air bag 704 is preferably a non-combustible and non-combustible gas, such as CO2. A puncture needle 705 is provided in the protective sleeve 702. The head of the puncture needle 705 is aligned with the compressed air bag 704. A connecting block 706 is provided at the tail of the puncture needle 705. An electromagnet 707 is provided in the protective sleeve 702. The electromagnet 707 is used to absorb the connecting block 706. The electromagnet 707 is electrically connected to the control unit.

[0050] When in use, the control unit controls the electromagnet 707 to start, thereby adsorbing the connecting block 706. The connecting block 706 slides quickly to drive the pricking needle 705 to slide. The pricking needle 705 slides to pierce the compressed airbag 704. The compressed airbag 704 ruptures and high-pressure gas is ejected, generating high pressure. The high pressure can push the push plate 703 out, thereby acting on the battery 4. The battery 4 is directly ejected due to the instantaneous high pressure, completing the ejection of the battery 4.

[0051] The present application can also be applied to existing ejection devices, and is not limited to using only the ejection structure disclosed in the present application.

[0052] Embodiment 6: A method for using a thermal runaway battery disposal device comprises the following steps: S1. The sensor monitors the battery status in real time. The control unit receives the signal detected by the sensor and makes a thermal runaway judgment. S2, the control unit determines that the battery has thermal runaway, and the control unit controls the ejection mechanism to start ejecting the battery from the battery compartment; The judgment procedure of the control unit can use the existing battery thermal runaway judgment method and procedure. For example, the sensor uses a temperature sensor and sets a thermal runaway temperature critical value.
