DETAILED DESCRIPTION

[0021] Referring to the drawings Figures 1-3 The utility model provides a kind of thermal runaway battery processing device for new energy commercial vehicle battery swap station, including water tank 1, bearing frame 2 for carrying thermal runaway battery and lifting drive assembly for driving thermal runaway battery on bearing frame 2 into the inside of water tank 1.The lifting drive assembly described above includes connecting support 3, roller 4, drive motor 5 for being fixed on connecting support 3 and driving roller 4 rotation, steel wire rope 6 being arranged between roller 4 and water tank 1 and pulley 7 being arranged on connecting support 3 and redirecting steel wire rope 6, connecting support 3 is fixed on water tank 1 and is located above the middle part of water tank 1.Through drive motor 5 drive roller 4 rotation realizes the winding or release of steel wire rope 6, in turn drives bearing frame 2 to move upwards or downwards.

[0022] When steel wire rope 6 is directly connected with bearing frame 2, it needs to be set on the outer side of bearing frame 2 to prevent thermal runaway battery from interfering with steel wire rope 6 when entering bearing frame 2, and also to cause the horizontal occupation space of the device to increase.To avoid interference between steel wire rope 6 and battery and reduce the occupied area of the device, lifting frame 8 in inverted U shape and connected with steel wire rope 6 is arranged on bearing frame 2 and inside connecting support 3.Lifting frame 8 is in inverted U shape, which facilitates the battery to pass through lifting frame 8 and enter bearing frame 2 as a whole.

[0023] When one lifting frame 8 is arranged, two rollers 4 are arranged on connecting support 3, and the two rollers 4 share one drive motor 5.Both ends of each roller 2 are fixed on connecting support 3 by bearing seat 18.The output shaft of drive motor 5 is connected with speed reducer 17 fixed on connecting support 3.The output shaft of speed reducer 17 penetrates the speed reducer housing, and the two ends are respectively connected with one roller 4.Steel wire ropes 6 on two rollers 4 are connected with the top two sides of lifting frame 8 after passing through corresponding pulleys 7.

[0024] Referring to the drawings Figures 1-3When two lifting platforms 8 are provided, the two lifting platforms 8 are arranged along the length direction of the bearing frame 2. Two steel wires 6 are arranged on each roller 4, and the two steel wires 6 are connected to the top of the two lifting platforms 8 after passing through the corresponding pulleys 7. A pulley 7 is arranged on the connecting support 3 for each steel wire 6. Two lifting platforms 8 are designed, and a steel wire connecting point is arranged on the top of each lifting platform 8. The four steel wire connecting points can realize stable lifting of the bearing frame 2, and can disperse the stress in the lifting process to the four steel wires, so that the device has good stability and safety. In this embodiment, two lifting platforms 8 are provided.

[0025] Referring to the accompanying drawings Figure 1 and 2 A lifting guide assembly is arranged between the two sides of the lifting platform 8 and the water tank 1, and the lifting guide assembly comprises a guide strip 9 arranged on the lifting platform 8 and a guide groove 1-1 arranged on the water tank 1 and matched with the guide strip 9. In the initial state, the lower end of the guide strip 9 is located in the guide groove 1-1. In this embodiment, the guide groove 1-1 is formed by two angle steels which are symmetrically fixed on the water tank 1 and have a gap.

[0026] Referring to the accompanying drawings Figure 1 and 2 A travel switch 10 is arranged on the top and bottom of the connecting support 3, and a driving plate 11 is arranged on the lifting platform 8 to drive the travel switch 10. The driving plate 11 moves up and down with the lifting platform 8 and controls the driving motor 5 to stop driving by touching the corresponding travel switch 10.

[0027] The bearing frame embodiment one: in this embodiment, the bearing frame 2 comprises two longitudinal beams 2-1 arranged side by side and a plurality of cross beams 2-2 connecting the two longitudinal beams 2-1, and an end limiting block 12 for limiting the end of the thermal runaway battery is arranged on the cross beam 2-2 at the end of the longitudinal beam 2-1. When the battery assembly moves into the bearing frame 2 and is finally limited by the end limiting block 12, the battery assembly as a whole enters the bearing frame 2.

[0028] The bearing frame 2 further comprises a guide plate 15 connected to the plurality of cross beams 2-2 and matched with the V-shaped groove of the bottom roller of the thermal runaway battery to form a guide structure. The guide plate 15 is arranged side by side with two, which preferably adopts an angle steel.

[0029] The bearing frame embodiment two: different from the embodiment one, in this embodiment, a horizontal limiting block 13 is arranged on the outer side or top of each longitudinal beam 2-1, and a limiting plate 14 limiting the horizontal limiting block 13 is arranged on the water tank 1, and the limiting plate 14 is located above the horizontal limiting block 13.

[0030] When the battery enters the carrier 2 by the entrance of the carrier 2, its weight adds the steel wire rope 6 loaded on the lifting platform 8 near the entrance in advance and causes the end of the carrier 2 to have a tendency of upward tilting. At this time, the bottom end of the guide strip 9 and the guide groove 1-1 are forced to resist this tendency, which can cause the guide strip 9 or the guide groove 1-1 to be deformed and lose the guiding effect. Therefore, the limiting plate 14 and the horizontal limiting block 13 are arranged to avoid damage to the guiding assembly.

[0031] Carrier embodiment three: different from embodiment two, in this embodiment, the lock pin limiting plate 16 for positioning the bottom lock pin of the thermal runaway battery is arranged on the longitudinal beam 2-1. The thermal runaway battery is axially limited by the lock pin limiting plate 16 and the end limiting block 12, which can prevent the battery from moving axially on the carrier 2 during lifting.

[0032] Taking the carrier embodiment three as an example, the working process of the device of the utility model is as follows.

[0033] a. When it is detected that the battery is in a thermal runaway state, the battery transfer equipment (such as battery replacement equipment, stacking equipment, etc.) will unlock the battery assembly from the battery rack and pull it into the battery transfer equipment.

[0034] b. The battery transfer equipment moves to the side of the battery entrance of the carrier 2. The push-pull device in the battery transfer equipment pushes the thermal runaway battery into the carrier 2 and is limited by the end limiting block 12. In this process, the unlocking device keeps the lock pin in the unlocking state of the locking assembly at the bottom of the battery sliding bracket, and the lock pin in the bracket does not affect the movement of the battery into the carrier 2. After the battery is pushed into place, the device is reset, and the unlocking device is no longer unlocked to the locking assembly at the bottom of the battery assembly. The lock pin extends out of the sliding bracket under the action of the matching spring, so that the battery is limited between the end limiting block 12 and the lock pin limiting plate 16, and the push-pull device drives the unlocking device to reset.

[0035] c. The driving motor 5 releases the steel wire rope 6 by driving the two rollers 4 through the speed reducer 17, and the carrier 2 and the battery thereon sink into the water in the water tank 1 to realize fire extinguishing treatment.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific implementation of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical scheme of the utility model, they should be covered in the technical scheme range of the utility model claimed to be protected.
