Description

Technical Field

[0001] The present invention belongs to the technical field of recycling and disassembling new energy power batteries, and in particular relates to a safe disassembly system and method for an accident power battery pack. Background Art

[0002] my country's new energy electric vehicle industry is experiencing rapid growth. With increasing government policy support, the market share of new energy electric vehicles continues to rise, leading to a corresponding increase in the number of battery packs scrapped after accidents involving electric vehicles. This favorable industry environment is driving continued investment in technological research and development by new energy vehicle and power battery manufacturers, resulting in a significant number of scrapped power battery packs after testing. Vehicle recycling and dismantling companies at the end of the automotive supply chain are also receiving an increasing number of damaged power battery packs.

[0003] Accident power battery packs mainly fall into the following categories: battery packs with severe structural deformation caused by mechanical damage such as extrusion and collision; battery packs that are completely or partially burned after catching fire; battery packs that have been soaked in water after an abnormal situation occurs, etc. Extrusion, collision and other factors cause the battery pack's shell or fasteners to deform, making it impossible to remove the pack shell and internal high-voltage connection harness through normal disassembly methods, making it impossible to discharge physically or by soaking in water; fire, soaking in water and other factors cause the internal high-voltage circuit of the battery pack to be broken, and some battery cell poles are corroded and cannot be discharged normally. Therefore, the modules or cells of the accident power battery pack may still store electrical energy, which may cause electric shock to people, battery fire and explosion, and the generation of large amounts of smoke and exhaust gas, causing serious personal injury to disassembly workers, fire, and leakage of toxic and harmful gases that damage the environment.

[0004] There are numerous battery pack models with diverse shapes and structures, and the damage to battery packs in accidents also varies. Currently, there are no established protocols or precedents for disassembling battery packs in accidents. The few disassemblies that occur are done manually or mechanically. Manual disassembly is difficult and poses a serious threat to the safety of operators. Mechanical disassembly can lead to explosions, fires, and the release of toxic and hazardous gases, which can damage the environment.

[0005] Therefore, a system for safely dismantling accident power battery packs is needed, which can not only meet the requirements of efficient dismantling of accident power battery packs, but also ensure the personal safety of dismantling personnel and meet the environmental protection requirements of dismantling operations. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a system and method for the safe disassembly of an accident-prone power battery pack. This safe disassembly system can not only efficiently disassemble accident-prone power battery packs of various structures, but also ensure the personal safety of disassembly personnel and meet environmental requirements for disassembly operations.

[0007] According to the first aspect of the present invention, a safe disassembly system for an accident power battery pack includes: an explosion-proof disassembly room, wherein a disassembly platform is provided in the explosion-proof disassembly room, and the disassembly platform includes an underwater demolition area and an underwater disassembly pool; a battery disassembly mechanism, which is located in the explosion-proof disassembly room and can cooperate with the disassembly platform to disassemble the accident power battery pack; a material loading and unloading mechanism, which can move the accident power battery pack into the explosion-proof disassembly room and can move the disassembled materials out of the explosion-proof disassembly room; an exhaust gas treatment mechanism, which is used to treat the exhaust gas generated by the explosion-proof disassembly room; a remote monitoring mechanism, which is used to remotely monitor the disassembly process of the accident power battery pack and can remotely control the battery disassembly mechanism, the material loading and unloading mechanism and the exhaust gas treatment mechanism, and when the accident power battery pack is disassembled, the explosion-proof disassembly room is in a sealed state.

[0008] According to an embodiment of the present invention, a safe disassembly system for an accident power battery pack has at least the following technical effects: an operator can remotely disassemble the accident power battery pack through the safe disassembly system for the accident power battery pack, and can continuously operate the accident power battery through a remote monitoring mechanism, a material feeding and discharging mechanism and a battery disassembly mechanism to achieve the purpose of efficient disassembly; at the same time, an accident power battery pack that is initially judged to be out of power can be directly controlled and disassembled in an underwater disassembly area, and an accident power battery pack that is initially judged to be charged can be disassembled underwater in an underwater disassembly pool to prevent fire and explosion; in addition, the exhaust gas generated in the explosion-proof disassembly room can be treated by the exhaust gas treatment mechanism, and during the disassembly process, the explosion-proof disassembly room is in a sealed state, which can effectively prevent the harmful gases generated during the disassembly process from overflowing, thereby meeting the efficient disassembly of the accident power battery pack, ensuring the personal safety of the operator, and meeting the environmental protection requirements of the disassembly operation.

[0009] According to some embodiments of the present invention, a spray mechanism is further included, which is remotely controlled by the remote monitoring mechanism and includes a dust suppression fog cannon and a fire water cannon installed above the disassembly platform. When smoke and dust are generated during the disassembly of the accident power battery pack by the operator, the dust suppression fog cannon can be remotely activated to remove the smoke and dust. When the accident power battery pack is disassembled in the non-water demolition area and an explosion occurs, the fire water cannon can be remotely activated to control the fire and extinguish it in a timely manner.

[0010] According to some embodiments of the present invention, a disassembly basket is provided in the underwater disassembly pool so that it can be raised and lowered, and the remote monitoring mechanism can control the raising and lowering of the disassembly basket. After the operator places the accident power battery pack, which is initially determined to be charged, in the disassembly basket through remotely controlled battery disassembly mechanism, the operator controls the disassembly basket to descend below the surface of the underwater disassembly pool. The accident power battery pack is disassembled in the disassembly basket so that the disassembled materials are in the disassembly basket. After the disassembly is completed, the disassembly basket is controlled to rise to the surface of the water, and then the battery disassembly mechanism is remotely controlled to transfer the disassembled materials to the inlet and outlet mechanism and move them out of the explosion-proof disassembly room.

[0011] Some embodiments of the present invention further include a circulating water tank connected to the underwater disassembly tank. Water in the underwater disassembly tank is pumped to the circulating water tank via a circulating water pump through a pipeline. Water is cooled and impurities are precipitated in the circulating water tank before being pumped back to the underwater disassembly tank for reuse. This effectively conserves water resources and ensures that the water in the underwater disassembly tank remains at a relatively low temperature during continuous operation.

[0012] According to some embodiments of the present invention, the bottom of the circulating water pool is provided with a slope, a sedimentation pool is provided at the bottom of the slope, and a sewage pipe is provided in communication with the sedimentation pool. Impurities in the circulating water pool settle on the slope at the bottom of the pool and are collected in the sedimentation pool via the slope. The sediment is then pumped out through the sewage pipe, thereby facilitating the treatment of the impurity sediment in the circulating water pool.

[0013] According to some embodiments of the present invention, the battery disassembly mechanism includes a disassembly machine movable within the explosion-proof disassembly room, the disassembly machine being equipped with a movable arm equipped with a gripper for disassembling the accident-prone power battery. An operator can remotely control the disassembly machine's movement within the explosion-proof disassembly room, the movement of the disassembly machine's arm, and the gripper to perform disassembly actions such as lifting, dragging, clamping, and twisting the accident-prone power battery pack through a remote monitoring mechanism.

[0014] According to some embodiments of the present invention, the dismantling machine is a hydraulic excavator.

[0015] According to some embodiments of the present invention, the feeding and discharging mechanism includes an automatic feeding door, a feeding conveyor line, an automatic discharging door, and a discharging conveyor line provided in the explosion-proof disassembly room. The automatic feeding door is linked to the feeding conveyor line. When the feeding conveyor line is feeding, the automatic feeding door opens. When feeding is completed, the automatic feeding door closes. The automatic discharging door is linked to the discharging conveyor line. When the discharging conveyor line is discharging, the automatic discharging door opens. When discharging is completed, the automatic discharging door closes. This ensures that the automatic feeding door and the automatic discharging door are in a normally closed state during the disassembly of the accident power battery pack, ensuring that the explosion-proof disassembly room is in a sealed state when the accident power battery pack is disassembled.

[0016] According to some embodiments of the present invention, the exhaust gas treatment mechanism is composed of an exhaust hood, an air duct, a spray tower, a fan, and a chimney. The exhaust hood is arranged at the top of the explosion-proof disassembly room. Under the action of the fan, the exhaust hood can guide the exhaust gas generated in the explosion-proof disassembly room through the air duct to the spray tower for treatment, and then discharge it through the chimney. The exhaust gas treatment mechanism can create a slightly negative pressure state in the explosion-proof disassembly room to prevent the exhaust gas in the explosion-proof disassembly room from leaking out. The exhaust hood has a fan-shaped structure and can cooperate with the air duct to efficiently collect the exhaust gas generated in the explosion-proof disassembly room under the action of the fan. The exhaust gas is then guided into the spray tower. The spray tower can collect dust particles in the exhaust gas and simultaneously treat toxic and harmful substances, purify the exhaust gas, and then discharge the exhaust gas that meets the standards through the chimney.

[0017] According to some embodiments of the present invention, the remote monitoring mechanism includes a surveillance imaging mechanism and an explosion-proof control room. The explosion-proof control room is equipped with a control platform. The surveillance imaging mechanism includes a monitoring terminal and a display terminal that cooperates with the monitoring terminal. The monitoring terminal is located in the explosion-proof disassembly room to collect information about the situation inside the explosion-proof disassembly room, and the display terminal is located in the explosion-proof control room. Operators in the explosion-proof control room can view the situation in the explosion-proof disassembly room through the display terminal and control the battery disassembly mechanism, the material loading and unloading mechanism, and the exhaust gas treatment mechanism through the control platform to complete the disassembly of the accident power battery pack.

[0018] According to some embodiments of the present invention, the monitoring terminal includes a video camera, a thermal imaging camera, and a sensor, wherein the sensor is at least one of a temperature sensor, a humidity sensor, a toxic and hazardous gas sensor, and a gas concentration sensor. The video camera assists the operator in observing the readiness of the inlet and outlet materials and assists the operator in remotely disassembling the accident power battery pack on the disassembly platform. The thermal imaging camera assists the operator in understanding the heat generation and energy release of the accident power battery pack at the disassembly site. The sensor can collect parameters such as temperature, humidity, toxic and hazardous gas detection, and combustible gas concentration detection in the explosion-proof disassembly room and transmit them to the explosion-proof control room.

[0019] According to some embodiments of the present invention, an observation window is provided on the wall of the explosion-proof disassembly room. The glass of the observation window is explosion-proof glass, and the inspection personnel can observe the working conditions in the explosion-proof disassembly room through the observation window.

[0020] According to some embodiments of the present invention, the explosion-proof control room is separated from the inner wall of the explosion-proof disassembly room by explosion-proof glass.

[0021] According to some embodiments of the present invention, the explosion-proof control room is built in the explosion-proof disassembly room in a suspended manner, an explosion-proof roof is provided on the top of the explosion-proof control room, and a staircase connected to the explosion-proof control room is provided on the outer wall of the explosion-proof disassembly room.

[0022] According to some embodiments of the present invention, a rotating seat is provided in the explosion-proof control room. When the dismantling machine is controlled to rotate, the rotating seat can rotate proportionally, thereby better satisfying the operator's observation field of view.

[0023] According to some embodiments of the present invention, the control platform is integrated on the rotary seat, which makes it more convenient for operators to perform control operations.

[0024] According to the second aspect of the present invention, the control method of the safe disassembly system of the accident power battery pack as described above includes the following steps:

[0025] (1) Turn on the power of the system and start the exhaust gas treatment mechanism through the remote monitoring mechanism to treat the gas in the explosion-proof disassembly room;

[0026] (2) manually loading the accident power battery pack to be disassembled onto the loading and unloading mechanism, and controlling the loading and unloading mechanism through the remote monitoring mechanism to transfer the accident power battery pack to the disassembly platform;

[0027] (3) The battery disassembly mechanism is controlled by the remote monitoring mechanism to disassemble the accident power battery pack, wherein the accident power battery pack that is confirmed to be uncharged can be directly disassembled by the battery disassembly mechanism in the out-of-water disassembly area, and the accident power battery pack that cannot be confirmed to be charged is moved to the underwater disassembly pool by the battery disassembly mechanism and disassembled underwater by the battery disassembly mechanism;

[0028] (4) Controlling the battery disassembly mechanism through the remote monitoring mechanism to move the disassembled materials to the feeding and discharging mechanism, and controlling the feeding and discharging mechanism through the remote monitoring mechanism to move the disassembled materials out of the explosion-proof disassembly room, and manually unloading the materials;

[0029] (5) Shutting down the exhaust gas treatment mechanism and the system power supply via the remote monitoring mechanism.

[0030] Specifically, the control method of the safe disassembly system of the accident power battery pack as described above includes the following steps:

[0031] (1) The operator enters the explosion-proof control room via the stairs, turns on the power of the equipment, turns on the fan of the exhaust gas treatment mechanism, checks the status of each device, and prepares for disassembly;

[0032] (2) The loading and unloading staff uses a forklift to place the accident power battery pack on the pallet on the feeding conveyor line of the loading and unloading mechanism. After the operator observes through the display terminal that the accident power battery pack to be fed is ready, he presses the feeding button, the automatic feeding door opens, and the feeding conveyor line conveys the accident power battery pack into the explosion-proof disassembly room, and then the automatic feeding door closes automatically. The operator remotely operates the disassembly machine to clamp the accident power battery pack from the pallet of the feeding conveyor line to the disassembly platform, and then presses the feeding reset button, the automatic feeding door opens, the feeding conveyor line runs in reverse, and the empty pallet with the accident power battery pack is conveyed out of the explosion-proof disassembly room, and then the automatic feeding door closes automatically;

[0033] (3) The operator remotely operates the dismantling machine to dismantle the accident power battery pack placed on the dismantling platform. There are two types of dismantling operations, and the operator selects one based on the actual situation of the accident power battery pack:

[0034] ① The accident power battery pack is directly dismantled in the dismantling area outside the water: Use a dismantling machine to clamp the upper cover of the accident power battery pack and tear it off the battery pack; then clamp the battery cell or module, and rotate the clamp to twist off the battery cell or module; during the dismantling process, the internal short circuit and heating of the battery can be observed through the thermal imaging camera. When clamping the battery module or cell, if smoke appears, turn on the dust suppression fog cannon to remove smoke and dust. If a small fire occurs in the battery, turn on the fire water cannon to extinguish the fire. If the fire is large, use the dismantling machine to move the battery pack into the underwater dismantling pool for dismantling;

[0035] ② Dismantle the accident power battery pack in the underwater dismantling pool: First, check that the dismantling basket in the underwater dismantling pool has sunk into place. Then, operate the dismantling machine to clamp the accident power battery pack and place it in the dismantling basket. Then, operate the dismantling machine underwater to loosen the cells or modules in the battery pack, so that the battery cells or modules fall off from the battery pack shell. If the battery pack is charged, release the electricity in the water. After the bubbles and smoke subside, raise the dismantling basket and observe the internal heating of the battery through thermal imaging infrared monitoring.

[0036] (4) After the battery pack is disassembled, the disassembly machine is used to pick up the broken battery cells and other disassembled materials and put them into the material box filled with water prepared on the discharge conveyor line. The fire water monitor is turned on by remote control. The disassembly machine picks up the bottom shell of the battery pack, rinses it clean, and places it on the tray prepared on the discharge conveyor line;

[0037] (5) After the operator has prepared the materials to be discharged, he presses the discharge button, the automatic discharge door opens, and the discharge conveyor line conveys the disassembled products out of the explosion-proof disassembly room. Then the automatic discharge door closes automatically, and the loading and unloading staff uses a forklift to transfer the disassembled products and put the material box filled with water and the empty pallet back on the discharge conveyor line outside the explosion-proof disassembly room. After the operator observes that the material box and the empty pallet are ready through the display terminal, he presses the discharge reset button, the automatic discharge door opens, and the discharge conveyor line runs in reverse, conveying the material box filled with water and the empty pallet to the explosion-proof disassembly room to prepare for the next disassembly;

[0038] (6) After the disassembly is completed, turn off the fan 404 of the exhaust gas treatment mechanism and turn off the power supply of the equipment.

[0039] Through the above control method, during the disassembly of the accident power battery pack:

[0040] (1) After the exhaust gas treatment mechanism is turned on, the fan extracts the gas in the explosion-proof disassembly room through the air duct and the gas collecting hood, so that the explosion-proof disassembly room forms a slightly negative pressure state. Under the negative pressure state, the exhaust gas in the explosion-proof disassembly room will not leak out. The exhaust gas generated in the explosion-proof disassembly room passes through the spray tower, and the dust particles in the exhaust gas are washed into the washing liquid. The toxic and harmful substances in the exhaust gas react with the chemical agents in the washing liquid to neutralize them, and the remaining clean gas is discharged to the high altitude through the chimney to meet the standards;

[0041] (2) During the continuous disassembly process, the water temperature in the underwater disassembly pool will rise. There is an underwater disassembly pool water temperature display in the explosion-proof control room, which displays the water temperature in real time. When the water temperature is higher than the set value, the circulating water pump will automatically start for circulating cooling. During the water circulation process, impurities in the circulating water pool will be precipitated;

[0042] (3) The bottom of the circulating water pool adopts a slope structure, and there is a sedimentation pool at the bottom of the slope. The impurities in the circulating water pool are precipitated on the slope at the bottom of the pool and collected in the sedimentation pool. The dredging pump in the sedimentation pool pumps the sediment through the sewage pipe to the collection box outside the circulating water pool. The sediment is transferred and processed separately.

[0043] The beneficial effects of the present invention are:

[0044] (1) The safe disassembly system for accident power battery packs of the present invention can meet the requirements of efficient disassembly of accident battery packs of various structures through remote control;

[0045] (2) The safe disassembly system of the accident power battery pack of the present invention can adopt specific disassembly methods for accident power battery packs in different situations, which can effectively prevent explosions and open flames during the disassembly process and ensure the personal safety of operators;

[0046] (3) The explosion-proof disassembly room in the safe disassembly system of the accident power battery pack of the present invention is sealed during the disassembly process of the accident power battery pack, and the explosion-proof disassembly room is connected to an exhaust gas treatment mechanism, which can effectively prevent the leakage of toxic and harmful gases, thereby ensuring the environmental protection requirements of the operation;

[0047] (4) Since the explosion-proof disassembly room in the safe disassembly system of the accident power battery pack of the present invention is in a sealed state during the disassembly process of the accident power battery pack, the exhaust gas treatment mechanism can adopt smaller pipes and smaller-power fans, thereby maintaining a slightly negative pressure state in the disassembly room at low cost and low energy consumption.

[0065] Reference below Figures 1 to 4 A safe disassembly system for an accident power battery pack according to an embodiment of the present invention is described.

[0066] like Figure 1 and Figure 2As shown, a safe disassembly system for an accident power battery pack according to an embodiment of the present invention includes: an explosion-proof disassembly room 100, a battery disassembly mechanism, a material loading and unloading mechanism, an exhaust gas treatment mechanism and a remote monitoring mechanism; a disassembly platform is provided in the explosion-proof disassembly room 100, and the disassembly platform includes an out-of-water demolition area 101 and an underwater disassembly pool 102; the battery disassembly mechanism is located in the explosion-proof disassembly room 100 and can cooperate with the disassembly platform to disassemble the accident power battery pack; the material loading and unloading mechanism can move the accident power battery pack into the explosion-proof disassembly room 100 and can move the disassembled materials out of the explosion-proof disassembly room 100; the exhaust gas treatment mechanism is used to treat the exhaust gas generated by the explosion-proof disassembly room 100; the remote monitoring mechanism is used to remotely monitor the disassembly process of the accident power battery pack and can remotely control the battery disassembly mechanism, the material loading and unloading mechanism and the exhaust gas treatment mechanism, and when the accident power battery pack is disassembled, the explosion-proof disassembly room 100 is in a sealed state.

[0067] Specifically, in some specific embodiments of the present invention, the walls and floors of the explosion-proof disassembly room 100 are made of reinforced concrete to meet the fire and explosion prevention requirements. The operator can remotely disassemble the accident power battery pack through the safe disassembly system of the accident power battery pack, and can continuously operate the accident power battery through the remote monitoring mechanism, the feeding and discharging mechanism and the battery disassembly mechanism to achieve the purpose of efficient disassembly; at the same time, the accident power battery pack that is initially judged to be out of power can be directly controlled and disassembled in the outdoor disassembly area 101, and the accident power battery pack that is initially judged to be charged can be disassembled underwater in the underwater disassembly pool 102 to prevent fire and explosion; in addition, the exhaust gas generated in the explosion-proof disassembly room can be treated by the exhaust gas treatment mechanism, and during the disassembly process, the explosion-proof disassembly room is in a sealed state, which can effectively prevent the harmful gases generated during the disassembly process from overflowing, thereby meeting the efficient disassembly of the accident power battery pack, ensuring the personal safety of the operator, and meeting the environmental protection requirements of the disassembly operation.

[0068] In some specific embodiments of the present invention, a spray mechanism is further included. The spray mechanism is remotely controlled by a remote monitoring mechanism. The spray mechanism includes a dust suppression fog cannon 601 and a fire water cannon 602 arranged above the dismantling platform.

[0069] Specifically, if Figure 2 and Figure 3 As shown, multiple dust suppression fog cannons 601 and fire water cannons 602 are staggered along the length direction of the dismantling platform. When thick smoke and dust are generated during the dismantling of the accident power battery pack by the operator, the dust suppression fog cannon 601 can be remotely activated to remove smoke and dust. When the accident power battery pack is dismantled in the outside water demolition area 101 and an explosion is generated to form an open flame, the fire water cannon 602 can be remotely activated to control the fire and extinguish the fire in time.

[0070] like Figure 2 and Figure 3As shown, in some specific embodiments of the present invention, a disassembly basket 103 is provided in the underwater disassembly pool 102 so as to be liftable, and a remote monitoring mechanism can control the disassembly basket 103 to be lifted up and down.

[0071] Specifically, the disassembly basket 103 is composed of a profile and a mesh plate. The disassembly basket 103 is treated with anti-corrosion to prevent the disassembly basket 103 from being corroded by long-term immersion in wastewater containing electrolyte. The disassembly basket 103 is a compact frame structure that is firm and durable. Four hydraulic cylinders 105 are arranged around the underwater disassembly pool 102. The four hydraulic cylinders 105 are respectively connected to the disassembly basket 103 to drive the disassembly basket 103 up and down. The operator remotely controls the battery disassembly mechanism to After the charged accident power battery pack is placed in the disassembly basket 103, the hydraulic cylinder 105 is controlled to drive the disassembly basket 103 to descend below the water surface of the underwater disassembly pool 102, and the accident power battery pack is disassembled in the disassembly basket 103 so that the disassembled materials are in the disassembly basket 103. After the disassembly is completed, the hydraulic cylinder 105 is controlled to drive the disassembly basket 103 to rise to the water surface, and then the battery disassembly mechanism is remotely controlled to transfer the disassembled materials to the feed and discharge mechanism and move them out of the explosion-proof disassembly room 100.

[0072] In some specific embodiments of the present invention, a circulating water pool 701 is further included, which is connected to the underwater disassembly pool 102. The water in the underwater disassembly pool 102 is pumped to the circulating water pool 701 through a pipeline by a circulating water pump. After being cooled and impurities precipitated in the circulating water pool 701, the water is pumped back to the underwater disassembly pool 102 for reuse, thereby effectively saving water resources and ensuring that the water in the underwater disassembly pool 102 is always at a low temperature during continuous operation.

[0073] In some specific embodiments of the present invention, a slope is provided at the bottom of the circulating water pool 701, and a sedimentation pool 702 is provided at the bottom of the slope. Sedimentation pool 702 is connected to a sewage pipe 703. Impurities in the circulating water pool 701 settle on the slope at the bottom of the pool and are collected in the sedimentation pool 702 through the slope. The sediment is then pumped out through the sewage pipe 703, thereby facilitating the treatment of the impurity precipitation in the circulating water pool 701.

[0074] In some specific embodiments of the present invention, the battery disassembly mechanism includes a disassembly machine 201 that can move within the explosion-proof disassembly room 100. The disassembly machine 201 is provided with a movable arm 202, and the arm 202 is equipped with a clamp 203 for disassembling an accident power battery.

[0075] Specifically, if Figure 3-4As shown, the dismantling machine 201 is a hydraulic excavator, which is equipped with a remote operating system that can be remotely operated by an operator. A gate 106 for the dismantling machine 201 to enter and exit is installed on the explosion-proof dismantling room 100. The operator can remotely control the movement of the dismantling machine 201 in the explosion-proof dismantling room 100 through a remote monitoring mechanism, remotely control the movement of the arm 202 of the dismantling machine 201, and remotely control the gripper 203 of the dismantling machine 201 to perform dismantling actions such as grabbing, dragging, clamping, and twisting the accident power battery pack.

[0076] In some specific embodiments of the present invention, the feeding and unloading mechanism includes an automatic feeding door 301, a feeding conveyor line 302, an automatic discharging door 303 and a discharging conveyor line 304 arranged on the explosion-proof disassembly room 100. The automatic feeding door 301 is linked with the feeding conveyor line 302. When the feeding conveyor line 302 is running to feed, the automatic feeding door 301 opens. When the feeding is completed, the automatic feeding door 301 closes. The automatic discharging door 303 is linked with the discharging conveyor line 304. When the discharging conveyor line 304 is running to discharging, the automatic discharging door 303 opens. When the discharging is completed, the automatic discharging door 303 closes.

[0077] Specifically, the feed conveyor line 302 and the discharge conveyor line 304 are both plate chain conveyor lines. Both the feed conveyor line 302 and the discharge conveyor line 304 are sunken installations, and the conveying surface is level with the ground to facilitate the placement and transfer of material boxes and pallets. The feed conveyor line 302 and the discharge conveyor line 304 are both half inside the explosion-proof disassembly room 100 and half outside the explosion-proof disassembly room 100, and both the feed conveyor line 302 and the discharge conveyor line 304 can operate in both directions, which can ensure that the automatic feed door 301 and the automatic discharge door 303 are in a normally closed state during the disassembly of the accident power battery pack, ensuring that the explosion-proof disassembly room 100 is in a sealed state when the accident power battery pack is disassembled.

[0078] In some specific embodiments of the present invention, the exhaust gas treatment mechanism comprises an air hood 401, an air duct 402, a spray tower 403, a fan 404, and a chimney 405. The air hood 401 is disposed at the top of the explosion-proof disassembly room 100. Under the action of the fan 404, the air hood 401 can guide the exhaust gas generated by the explosion-proof disassembly room 100 through the air duct 402 to the spray tower 403 for treatment, and then discharge it through the chimney 405. The exhaust gas treatment mechanism can create a slightly negative pressure state in the explosion-proof disassembly room 100 to prevent the exhaust gas in the explosion-proof disassembly room 100 from leaking out. The air hood 401 has a fan-shaped structure and, in conjunction with the air duct 402, under the action of the fan 404, can efficiently collect the exhaust gas generated by the explosion-proof disassembly room 100. The exhaust gas is then guided into the spray tower 403. The spray tower 403 can collect dust particles in the exhaust gas and simultaneously treat toxic and hazardous substances, purifying the exhaust gas. The exhaust gas that meets the standards is then discharged through the chimney 405.

[0079] In some specific embodiments of the present invention, the remote monitoring mechanism includes a monitoring imaging mechanism and an explosion-proof control room 501. A control platform 502 is provided in the explosion-proof control room 501. The monitoring imaging mechanism includes a monitoring terminal 503 and a display terminal 504 that cooperates with the monitoring terminal 503. The monitoring terminal 503 is provided in the explosion-proof disassembly room 100 for collecting information about the conditions in the explosion-proof disassembly room 100. The display terminal 504 is provided in the explosion-proof control room 501. Operators can view the conditions in the explosion-proof disassembly room 100 through the display terminal 504 in the explosion-proof control room 501 and control the battery disassembly mechanism, the material loading and unloading mechanism, and the exhaust gas treatment mechanism through the control platform 502 to complete the disassembly of the accident power battery pack.

[0080] In some specific embodiments of the present invention, the monitoring terminal 503 includes a video camera, a thermal imaging camera and a sensor, and the sensor is at least one of a temperature sensor, a humidity sensor, a toxic and harmful gas sensor and a gas concentration sensor.

[0081] Specifically, multiple monitoring terminals 503 are set up around the disassembly platform and on the outer walls of the explosion-proof disassembly room. Video cameras assist operators in observing the ready status of input and output materials and assist operators in remotely disassembling the accident power battery pack on the disassembly platform. Thermal imaging cameras assist operators in understanding the heat generation and power release of the accident power battery pack at the disassembly site. Sensors can collect parameters such as temperature, humidity, toxic and harmful gas detection, and combustible gas concentration detection in the explosion-proof disassembly room and transmit them to the explosion-proof control room 501.

[0082] In some specific embodiments of the present invention, an observation window 104 is provided on the wall of the explosion-proof disassembly room 100 .

[0083] Specifically, the glass of the observation window 104 is explosion-proof glass, and the inspection personnel can observe the working conditions in the explosion-proof disassembly room 100 through the observation window 104 .

[0084] In some specific embodiments of the present invention, the explosion-proof control room 501 is separated from the inner wall of the explosion-proof disassembly room 100 by explosion-proof glass.

[0085] In some specific embodiments of the present invention, an explosion-proof control room 501 is suspended within the explosion-proof disassembly room 100. An explosion-proof roof is installed on top of the explosion-proof control room 501, and a staircase 107 is installed on the outer wall of the explosion-proof disassembly room 100, connecting to the explosion-proof control room 501. Operators can overlook the entire situation within the explosion-proof disassembly room 100 through the glass walls of the explosion-proof control room 501, thereby gaining a timely understanding of all dynamics within the explosion-proof disassembly room 100. Operators can fully control various equipment in the explosion-proof disassembly room 100 from within the explosion-proof control room 501. A cleaning device is installed on the outside of the glass of the explosion-proof control room 501 to automatically clean water mist and dust from the glass.

[0086] In some specific embodiments of the present invention, a rotating seat 505 is provided in the explosion-proof control room 501. When the dismantling machine 201 is controlled to rotate, the rotating seat 505 can rotate proportionally, thereby better satisfying the operator's observation field of view.

[0087] In some specific embodiments of the present invention, the control platform 502 is integrated on the rotating seat 505, and multiple function buttons such as ventilation, lighting, loading and unloading, fire fighting, flushing, and lifting and lowering of the disassembly basket 103 are integrated on the control platform 502, which can make it more convenient for operators to perform control operations.

[0088] According to the second aspect of the present invention, the control method of the safe disassembly system of the accident power battery pack as described above includes the following steps:

[0089] (1) Turn on the power of the system and activate the exhaust gas treatment mechanism through the remote monitoring mechanism to treat the gas in the explosion-proof disassembly room 100;

[0090] (2) Manually load the accident power battery pack to be disassembled onto the loading and unloading mechanism, and control the loading and unloading mechanism through the remote monitoring mechanism to transfer the accident power battery pack to the disassembly platform;

[0091] (3) The battery disassembly mechanism is controlled by the remote monitoring mechanism to disassemble the accident power battery pack. The accident power battery pack that is confirmed to be uncharged can be directly disassembled by the battery disassembly mechanism in the underwater disassembly area 101. The accident power battery pack that cannot be confirmed to be charged is moved to the underwater disassembly pool 102 by the battery disassembly mechanism and disassembled underwater by the battery disassembly mechanism.

[0092] (4) The battery disassembly mechanism is controlled by the remote monitoring mechanism to move the disassembled materials to the feeding and discharging mechanism, and the feeding and discharging mechanism is controlled by the remote monitoring mechanism to move the disassembled materials out of the explosion-proof disassembly room 100, and the materials are manually unloaded;

[0093] (5) Shutting down the exhaust gas treatment mechanism and the system power supply via the remote monitoring mechanism.

[0094] In some specific embodiments of the present invention, the control method of the safe disassembly system of the accident power battery pack as described above includes the following steps:

[0095] (1) The operator enters the explosion-proof control room 501 via the stairs 107, turns on the power of the equipment, turns on the fan 404 of the exhaust gas treatment mechanism, checks the status of each equipment system, and prepares for disassembly;

[0096] (2) The loading and unloading staff uses a forklift to fork the accident power battery pack onto the pallet on the feeding conveyor line 302 of the loading and unloading mechanism. After the operator observes through the display terminal 504 that the accident power battery pack to be fed is ready, he presses the feeding button, the automatic feeding door 301 opens, and the feeding conveyor line 302 conveys the accident power battery pack into the explosion-proof disassembly room 100, and then the automatic feeding door 301 automatically closes. The operator remotely operates the disassembly machine 201 to clamp the accident power battery pack from the pallet of the feeding conveyor line 302 to the disassembly platform, and then presses the feeding reset button, the automatic feeding door 301 opens, and the feeding conveyor line 302 runs in reverse, and the empty pallet on which the accident power battery pack is placed is conveyed out of the explosion-proof disassembly room 100, and then the automatic feeding door 301 automatically closes;

[0097] (3) The operator remotely operates the dismantling machine 201 to dismantle the accident power battery pack placed on the dismantling platform. The dismantling operation has the following two forms, and the operator selects one according to the actual situation of the accident power battery pack:

[0098] ① The accident power battery pack is directly dismantled in the dismantling area 101 outside the water: Use the dismantling machine 201 to clamp the upper cover of the accident power battery pack and tear it off the battery pack; then clamp the battery cell or module, and rotate the clamp to twist off the battery cell or module; during the dismantling process, the internal short circuit and heating of the battery can be observed through the thermal imaging camera. When clamping the battery module or cell, if smoke occurs, turn on the dust suppression fog cannon 601 to remove smoke and dust. If a small fire occurs in the battery, turn on the fire water cannon 602 to extinguish the fire. If the fire is large, use the dismantling machine 201 to move the battery pack into the underwater dismantling pool 102 for dismantling;

[0099] ② Dismantling the accident power battery pack in the underwater dismantling pool 102: First, check that the dismantling basket 103 in the underwater dismantling pool 102 has sunk into place. Then, operate the dismantling machine 201 to clamp the accident power battery pack and place it in the dismantling basket 103. Then, operate the dismantling machine 201 to separate the cells or modules in the battery pack underwater, so that the battery cells or modules fall off from the battery pack shell. If the battery pack is charged, the electricity is released in the water. After the bubbles and smoke subside, raise the dismantling basket 103 and observe the internal heating of the battery through thermal imaging infrared monitoring.

[0100] (4) After the battery pack is disassembled, the disassembly machine 201 is used to pick up the broken battery cells and other disassembled materials and put them into the material box filled with water prepared on the discharge conveyor line 304. The fire water monitor 602 is remotely turned on. The disassembly machine 201 picks up the bottom shell of the battery pack, rinses it clean, and places it on the tray prepared on the discharge conveyor line 304.

[0101] (5) After the operator has prepared the materials to be discharged, he presses the discharge button, the automatic discharge door 303 opens, and the discharge conveyor line 304 conveys the disassembled products out of the explosion-proof disassembly room 100. Then the automatic discharge door 303 closes automatically, and the loading and unloading staff uses a forklift to transfer the conveyed disassembled products and put the material box filled with water and the empty pallet back on the discharge conveyor line 304 outside the explosion-proof disassembly room 100. After the operator observes that the material box and the empty pallet are ready through the display terminal 504, he presses the discharge reset button, the automatic discharge door 303 opens, and the discharge conveyor line 304 runs in reverse, conveying the material box filled with water and the empty pallet to the explosion-proof disassembly room 100 to prepare for the next disassembly;

[0102] (6) After the disassembly is completed, turn off the fan 404 of the exhaust gas treatment mechanism and turn off the power supply of the equipment.

[0103] Through the above control method, during the disassembly of the accident power battery pack:

[0104] (1) After the exhaust gas treatment mechanism is turned on, the fan 404 draws the gas in the explosion-proof disassembly room 100 out through the air duct 402 and the gas collecting hood 401, so that the explosion-proof disassembly room 100 forms a slightly negative pressure state. Under the negative pressure state, the exhaust gas in the explosion-proof disassembly room 100 will not leak out. The exhaust gas generated in the explosion-proof disassembly room 100 passes through the spray tower 403, and the dust particles in the exhaust gas are washed into the washing liquid. The toxic and harmful substances in the exhaust gas react with the chemical agents in the washing liquid to neutralize each other, and the remaining clean gas is discharged to a high altitude through the chimney 405 to meet the standards;

[0105] (2) During the continuous disassembly process, the water temperature in the underwater disassembly pool 102 will rise. There is a water temperature display for the underwater disassembly pool 102 in the explosion-proof control room 501, which displays the water temperature in real time. When the water temperature is higher than the set value, the circulating water pump will be automatically turned on for circulating cooling. During the water circulation process, impurities in the circulating water pool 701 will be precipitated;

[0106] (3) The bottom of the circulating water pool 701 adopts a sliding slope structure, and there is a sedimentation pool 702 at the bottom of the slope. The impurities in the circulating water pool 701 are precipitated on the sliding slope at the bottom of the pool and collected in the sedimentation pool 702. The silt removal pump in the sedimentation pool 702 pumps the sediment through the sewage pipe 703 to the collection box outside the circulating water pool 701. The sediment is transferred and processed separately.

[0107] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] Of course, the invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
