[0002] Wind and solar power cannot operate continuously for 24 hours due to the influence of the natural environment, and their grid connection has a great impact on the power grid, which restricts their development.

[0003] To address this issue, the government encourages the establishment of energy storage power stations. These stations act as a bridge between power generation equipment and the power grid. Each energy storage power station is composed of numerous energy storage batteries, which, as the medium for storing electrical energy, require high-energy-density batteries.

[0004] Currently, energy storage batteries are all installed in containers, with multiple batteries installed in a single container. However, energy storage batteries are susceptible to thermal runaway. If thermal runaway occurs, it can damage the batteries inside the container and even trigger an interlocking reaction, leading to an explosion of the batteries in one container, which in turn affects the entire energy storage power station. Once an explosion occurs, the economic losses and social impact will be unbearable.

Detailed Implementation

[0024] Example 1: like Figure 1 , 2 As shown in Figures 3 and 4, a thermal runaway battery disposal device includes a housing 1, which refers to the housing structure commonly used in existing energy storage power stations for installing batteries 4, and a disposal base 2 is provided at the bottom of the housing 1. The housing 1 is equipped with multiple battery compartments 3. The battery compartments 3 are tilted so that the batteries 4 can be ejected when discarded. Gravity is used to assist in the removal of the batteries, thereby improving the processing efficiency. The battery compartment 3 is equipped with an ejection mechanism 7; Battery compartment 3 is used to house battery 4; ejection mechanism 7 is used to eject thermally runaway battery 4 from battery compartment 3; disposal base 2 is used to collect and dispose of thermally runaway battery 4; battery 4 refers to the battery used in the container, that is, the battery commonly used in energy storage power stations.

[0025] When in use, if the battery 4 in the battery compartment 3 experiences thermal runaway, the battery 4 will be ejected directly by the ejection mechanism 7 to prevent the thermal runaway battery 4 from affecting other batteries. At the same time, the ejected battery 4 will be collected and disposed of by the disposal base 2 to prevent the thermal runaway battery from affecting the surrounding environment, avoid further damage, and make disposal more convenient.

[0026] In a preferred embodiment, the housing 1 contains multiple isolation blocks 102, and the battery compartment 3 is located on both sides of the isolation blocks 102. The side of the battery compartment 3 closest to the isolation blocks 102 is higher than the other side of the battery compartment 3. Figure 4 The setup shown allows both ends to operate independently, and the isolation block 102 can also be used to set up connection lines or control lines. The bottom of the housing 1 is provided with a base 101, which is connected to the disposal base 2. A distance is created between the housing 1 and the disposal base 2 through the base 101 to avoid the disposal base 2 from affecting the battery 4 inside the housing 1 when handling the battery. If necessary, a heat insulation plate is installed inside the base 101.

[0027] The battery compartment 3 is equipped with multiple sensors 103. The sensors 103 are electrically connected to the control unit. The sensors 103 can be existing sensors used to monitor whether the battery is thermally runaway, such as temperature sensors, image sensors, and light sensors. The temperature sensor is used to monitor the temperature inside the battery compartment 3 and transmit it to the control unit to determine whether it is overheating. The image sensor is used to monitor the image of the battery 4 and transmit it to the control unit to determine whether it is bulging or damaged. The light sensor is used to monitor whether the battery 4 emits light and transmit it to the control unit to determine whether there is a spark.

[0028] Sensor 103 is used to monitor signals inside battery compartment 3 and transmit them to control unit. Control unit determines whether battery 4 is thermally runaway. Control unit can use existing or commonly used fixed control equipment in energy storage power station, such as PLC.

[0029] Example 2: like Figure 1 , 2 As shown in Figures 3 and 4, the discard base 2 includes a fixed seat 201 located at the bottom of the box 1, a water tank 202 located inside the fixed seat 201, and a support plate 205 located inside the water tank 202. The water tank 202 is separated into two parts by the support plate 205, so that the batteries 4 that pop out on both sides of the box 1 will not affect each other.

[0030] The mounting base 201 is provided with two entry holes 203. The two entry holes 203 are respectively connected to the two parts of the water tank 202 separated by the support plate 205. The entry holes 203 are connected to the water tank 202. The bottom surface of the entry hole 203 is a slope, which makes it easier for the falling 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 fixed base 201. The water inlet seat 204 is provided with a water inlet pipe 206, which is connected to the water tank 202. The water inlet pipe 206 is connected to an external water source, preferably ice water, and is connected to a solenoid valve. The solenoid valve is electrically connected to the control unit.

[0031] On the other side of the fixed base 201, there is a processing box 209. The processing box 209 is connected to the water tank 202. The top of the processing box 209 is provided with a processing hole and a box cover 210, and the box cover 210 covers the processing hole. The treatment box 209 is preferably a thickened box body. The top of the box body is equipped with an overflow pipe and the bottom of the box body is equipped with a water outlet pipe. The water outlet pipe is equipped with a solenoid valve. Both the overflow pipe and the water outlet pipe are connected to the sewage treatment tank. The internal volume of the treatment box 209 is determined according to the actual situation. The treatment box 209 is buried underground, and the box wall of the treatment box 209 is thickened and corrosion-resistant.

[0032] When in use, the water tank 202 is tilted, with the end near the water inlet pipe 206 higher than the end near the treatment tank 209.

[0033] In use, when the control unit determines that the corresponding battery has thermal runaway, it controls the ejection mechanism 7 to eject the corresponding battery. At the same time, it opens the solenoid valve of the water inlet pipe 206, allowing water to enter the water tank 202 through the water inlet pipe 206. The ejected battery 4 falls into the inlet hole 203 below, and then slides into the interior of the water tank 202 under the influence of the slope. The water can cool down the battery 4 and slow down the rate of thermal runaway. Then the battery 4 will be flushed into the treatment tank 209. The treatment tank 209 contains more water, which can completely submerge the battery 4 and keep it away from the tank body 1. This allows for timely treatment of the thermal runaway battery 4, avoiding affecting other batteries 4 and preventing the thermal runaway battery 4 from having an adverse impact on the surrounding environment.

[0034] In a further embodiment, when multiple boxes 1 are provided, the boxes 1 are arranged in a row, and the entrances and exits of the battery compartment 3 face the same direction; each box 1 is provided with a fixing seat 201 at its bottom; The water inlet seat 204 and the treatment box 209 are located at both ends of the box assembly. A connecting seat 207 is provided between the fixed seats 201 connecting adjacent boxes 1. The connecting seat 207 has a through hole 208 inside, which communicates with the water tank 202. Each connecting seat 207 has two through holes 208, which are used to connect the two parts of the water tank 202 respectively.

[0035] Preferably, the water tank 202 and the through hole 208 are in an inclined state, and the end near the water inlet pipe 206 is higher than the end near the treatment box 209, and the connection between the water tank 202 and the through hole 208 is smooth.

[0036] This allows multiple enclosures to be connected in series for use in large-scale energy storage power stations.

[0037] Example 3: To facilitate the ejection of battery 4, such as 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 at the top of the guide plate 301. The guide plate 301 is used to facilitate the sliding of the battery 4. At the same time, a roller can be provided at the top of the guide plate 301 to further facilitate the sliding of the battery 4.

[0038] The bottom of the battery compartment 3 entrance and exit is provided with a ramp 302 so that the battery 4 can slide down through the battery compartment 3 entrance and exit after being ejected; The battery compartment 3 has a first cover plate 303 at its entrance and exit, and a slit 304 is provided inside the first cover plate 303; The slit 304 can be referenced to a V-shaped cleavage, or it can be made by directly cutting through the material, leaving a small amount of uncut portion within the slit 304. Under stress, the first cover plate 303 can break directly along the slit 304. The bottom surface of the first cover plate 303 only contacts the bottom surface of the inner wall of the battery compartment 3, and the cut 304 is an inverted U-shape. The size of the cut 304 is larger than the size of the edge of the end face of the battery 4. When in use, the ejected battery 4 hits the first cover plate 303, and the first cover plate 303 breaks along the cut 304 due to the impact. Then the battery 4 continues to fly out, completing the ejection. Normally, it is protected by the first cover plate 303.

[0039] In a further embodiment, such as Figure 12 As shown, other identical structures will not be described in detail. The entrance and exit of the battery compartment 3 are provided with a second cover plate 305. The top of the second cover plate 305 is provided with a first rotating shaft 306. The second cover plate 305 is rotatably connected to the housing 1 through the first rotating shaft 306. The bottom of the second cover plate 305 is provided with a magnet 307, which attracts the box body 1.

[0040] When in use, the ejected battery 4 hits the second cover 305. The second cover 305 will rotate around the first pivot 306 when it is hit, and will no longer block the battery 4. The battery 4 will continue to fly out, completing the ejection. Normally, it will be protected by the second cover 305. The second cover 305 in this way can be reused.

[0041] Example 4: like Figure 6 , 7 As shown in Figures 8 and 11, the inner wall of the battery compartment 3 is provided with a guide rail 5, which is used to connect and guide the movement of the battery 4. The guide rail 5 includes a track 501 disposed on the inner wall of the battery compartment 3. A guide groove 504 is provided on the side of the track 501 near the battery 4. A sliding rod 502 is slidably connected in the guide groove 504. The side of the sliding rod 502 away from the track 501 is in close contact with 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. Preferably, multiple balls are provided in the track 501, and the balls are in contact with the sliding rod 502.

[0042] A limiting strip 505 is provided on the inner wall of the guide groove 504 near the edge of the battery 4. The limiting strip 505 extends into the interior of the sliding rod 502 and is slidably connected to the sliding rod 502. The limiting 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 the side of the sliding rod 502 near the battery 4. The fixed shaft 506 is located at the end of the sliding rod 502 near the inlet and outlet of the battery compartment 3. The fixed shaft 506 is rotatably connected to a rotating cylinder 507, which is located on the end face of the battery 4. The rotating cylinder 507 blocks the battery 4 to prevent it 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 sliding groove 508, and the sliding rod 502 is provided with a slider 509, which is located inside the sliding groove 508. The slider 509 and the sliding groove 508 restrict the position of the sliding rod 502 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 fixed sleeve 531 fixedly connected to the track 501. A spring 532 is provided inside the fixed sleeve 531. A positioning groove 534 is provided on the side of the sliding rod 502. A limiting ball 533 is provided on the spring 532. The limiting ball 533 extends into the interior 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, due to the influence of the circular groove and the spherical surface of the limiting ball 533, the force will generate a component force to counteract the force given by the spring 532, causing the limiting ball 533 to move away from the circular groove. At this time, the sliding rod 502 can slide normally.

[0046] In use, the ejection mechanism 7 ejects the battery 4, generating a significant thrust that directly pushes the battery 4 out. At this point, the battery 4 sequentially drives the rotating drum 507, the fixed shaft 506, and the sliding rod 502 to slide. During this sliding motion, the battery 4 is prevented from flying out directly due to the influence of the rotating drum 507. After sliding to its end, the battery 4 moves away from the battery compartment 3. Figure 11 As shown, battery 4 cannot fly out, but instead slides down under the influence of gravity and eventually falls into the inlet hole 203. This makes it easy to deal with the thermal runaway battery 4 and also prevents the battery 4 from flying too far away, thus avoiding impacting the surrounding environment.

[0047] Example 5: like Figure 6 and 9 As shown, a connecting mechanism 6 is provided between the battery 4 and the isolation block 102. The connecting mechanism 6 is used to connect the circuit. The connecting mechanism 6 includes a connecting sleeve 601 that is fixedly connected to the isolation block 102, and a power socket 602 is provided inside the isolation block 102; A baffle 603 is provided on the side of the connecting sleeve 601 near the battery 4, and the top of the baffle 603 is rotatably connected to the connecting sleeve 601 through a second rotating shaft 604; The bottom of the inner wall of the connecting sleeve 601 is provided with a limiting groove 605; Battery 4 is provided with a connector 606, which extends into the interior of the connecting sleeve 601. The connector 606 is electrically connected to the connector 602. Preferably, the connector 606 and the connector 602 are connected by a connecting piece contact type or a material connection plug type, as long as the connection is not locked after connection.

[0048] When the battery 4 is ejected, the connector 606 separates from the connector 602. At this time, the baffle 603 is not affected by the connector 606. Under the action of gravity, the baffle 603 rotates around the second pivot 604 until the bottom of the baffle 603 rotates to the limiting groove 605. At this time, the baffle 603 can cover the connector 602, thereby preventing the influence of fire sources on the connector 602 and ensuring the stability of the circuit.

[0049] In a further embodiment, such as Figure 6 and 10 As shown, the ejection mechanism 7 includes a pad 701 that is fixedly connected to the battery 4; The isolation block 102 is provided with a protective sleeve 702. The protective sleeve 702 has a cavity inside. A push plate 703 is provided on the side of the cavity near the battery 4. The push plate 703 is in contact with the pad block 701. The protective sleeve 702 has a compressed air bladder 704 inside its cavity. The compressed air bladder 704 is preferably filled with a non-flammable and non-combustible gas, such as CO2. The protective sleeve 702 has a barbed needle 705 inside its cavity. The head of the barbed needle 705 is aligned with the compressed air bladder 704, and the tail of the barbed needle 705 is provided with a connecting block 706. The protective sleeve 702 contains an electromagnet 707, which is used to attract the connecting block 706 and is electrically connected to the control unit.

[0050] In use, the control unit controls the electromagnet 707 to start, thereby attracting the connecting block 706. The connecting block 706 slides quickly, causing the piercing needle 705 to slide. The piercing needle 705 slides and pierces the compression airbag 704. The compression 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] This application can also be applied to existing catapult devices, and is not limited to using only the catapult structure disclosed in this application.

[0052] Example 6: A method of using a thermal runaway battery disposal device includes the following steps: S1. The sensor monitors the battery status in real time, and the control unit receives the signal detected by the sensor and makes a judgment on thermal runaway. S2. The control unit determines that the battery has thermal runaway and controls the ejection mechanism to start the ejection mechanism to eject the battery from the battery compartment. The control unit's judgment procedure can use the existing battery thermal runaway judgment methods and procedures. For example, if a temperature sensor is used, a thermal runaway temperature threshold can be set. When the sensor senses a temperature exceeding the threshold, the control unit will determine that the corresponding battery has experienced thermal runaway. The specific procedure depends on the actual situation.

[0053] S3. The control unit controls the water inlet to flow into the treatment tank; S4. The ejected battery falls downwards into the processing slot below; S5. The battery in the water inlet is submerged in the water treatment tank to cool the battery and reduce the rate of thermal runaway. S6. Water continuously enters from the inlet end, and the battery is affected by the water flow and enters the treatment tank along the treatment tank. The battery is completely submerged in the treatment tank. The liquid from battery disposal is treated using existing wastewater treatment methods before being discharged, with wastewater treatment standards referencing national standards.

[0054] Waste batteries shall be disposed of in accordance with the relevant standards, referring to existing national standards for disposal. The above steps complete the disposal and handling of the thermal runaway battery.

[0055] In the preferred embodiment, a limiting structure is set at the inlet and outlet of the battery compartment so that the ejected battery will not fly out, but will be stopped by the limiting structure and then fall into the processing tank. The water entering from the inlet is cooled. Through the above methods, this application not only facilitates the handling of thermally runaway batteries and prevents them from affecting other batteries, but also prevents electromagnetic emissions, thereby preventing the batteries from affecting the surrounding environment.

[0056] The methods of power transmission, signal transmission and power connection in this application can all adopt existing technologies, and will not be described in detail here.

[0057] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention.
