[0043] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] like Figure 1As shown, this invention discloses a treatment box for detecting and treating abnormal batteries. This treatment box includes: a water tank 1, a battery housing 2, a connecting water pipe 3, a door 4, and a smoke exhaust pipe 5. The water tank 1 is connected to the battery housing 2, and the connecting water pipe 3 connects the water tank 1 and the battery housing 2. The battery housing 2 has an opening 21, and the door 4 is closable at the opening 21. The smoke exhaust pipe 5 is connected to the battery housing 2 and is located near the upper surface of the battery housing. Specifically, the water tank 1 contains water, and the battery housing 2 contains batteries. When the treatment box begins detecting or treating abnormal batteries, the door 4 of the battery housing 2 is closed, and the connecting water pipe 3 transports water from the water tank 1 to the battery housing 2 to cool it down. As the detection or treatment of abnormal batteries progresses, the temperature of the abnormal batteries becomes very high, typically approaching 300°C. Therefore, the smoke generated by the high temperature is discharged from the treatment box through the smoke exhaust pipe 5. The disposal box provided by this invention is used to detect and process abnormal batteries. The cooling effect of water is used to cool down the abnormal batteries that are at high temperatures, thereby effectively reducing the possibility of explosion during the safety testing of power batteries, and the generated high-temperature fumes can be discharged from the disposal box in a timely manner.

[0045] like Figures 2 to 4 As shown, in a preferred embodiment of this invention, in the treatment box of the present invention, the water tank 1 is located above the battery housing 2. The left side of the water tank 1 is flush with the left side of the battery housing 2, the right side of the water tank 1 is flush with the right side of the battery housing 2, the rear surface of the water tank 1 is flush with the rear surface of the battery housing 2, the front surface of the battery housing 2 protrudes forward from the front surface of the water tank 1 and forms a stepped surface 22 on the upper surface of the battery housing 2. The stepped surface 22 connects the lower edge of the front surface of the water tank 1 and the upper edge of the front surface of the battery housing 2. An opening 21 is provided on the front surface of the battery housing 2. In this preferred embodiment, the treatment box has an upper and lower structure, with the battery housing 2 below and the water tank 1 above. The rear end faces and left and right sides of the battery housing 2 and the water tank 1 are flush. The front end face of the water tank 1 is recessed backward, that is, the top plate of the battery housing 2 protrudes forward from the bottom of the water tank 1 to form the stepped surface 22. Specifically, the treatment box is a square box, with the water tank 1 and the battery container 2 being two spaces separated by a horizontal partition. The front surface of the water tank 1 is closed, while the front surface of the battery container 2 is open and protrudes forward. According to this preferred embodiment, the exhaust pipe 5 is not affected by the shape of the treatment box, and when the door 4 is open, it can be placed on the stepped surface 22.

[0046] like Figure 3 and Figure 5As shown in a preferred embodiment of this invention, in the disposal box of the present invention, the door 4 is provided with a folded edge 41. The folded edge 41 folds from the surface of the door 4 facing the opening 21 toward the stepped surface 22. The distance between the connection point of the folded edge 41 and the door 4 and the lower edge of the door 4 is equal to the distance from the upper edge to the lower edge of the front surface of the battery container 2. In this preferred embodiment, the openable door 4 can move up and down. The inner surface of the door 4, preferably on the upper edge, is provided with a folded edge 41 folded toward the opening 21 of the battery container 2, which is L-shaped. Through this L-shaped folded edge 41, when the door 4 is in the closed state, it can be fastened to the stepped surface 22.

[0047] like Figure 5 As shown in the preferred embodiment, the treatment box of the present invention includes a control device 6 disposed on at least one of the left and right sides of the treatment box. The control device 6 controls the door 4 to close or open the opening 21. Each control device 6 includes a guide rail 61, a slider 62, and a push-pull element 63. The guide rail 61 is fixed to the corresponding side of the treatment box, the slider 62 is slidably connected to the guide rail 61, and the push-pull element 63 connects the slider 62 and the door 4. In this preferred embodiment, guide rails 61 are respectively provided on the left and right sides of the battery housing 2 near the opening 21. A slider 62 is provided inside the guide rail 61. The slider 62 is connected to one end of the push-pull element 63, and the other end of the push-pull element 63 is connected to the door 4. The push-pull elements 63 connected to the left and right sides of the door 4 are symmetrically arranged. Through the control device 6 in this preferred embodiment, the operator can manually push and pull the door 4, or the door 4 can be electrically controlled to push and pull using an electric controller.

[0048] like Figure 6 As shown, in a preferred embodiment of this invention, the push-pull element 63 in the disposal box of the present invention includes a main push rod 631, a main cylinder 632, two auxiliary push rods 633, two auxiliary cylinders 634, a baffle 635, and a connecting plate 636, with the connecting plate 636 fixed to the box door 4; one end of the main cylinder 632 is connected to the slider 62, and the other end of the main cylinder 632 is connected to the baffle 635; one end of the main push rod 631 is connected inside the main cylinder 632, and the main push rod... The other end of rod 631 is connected to connecting plate 636, and main push rod 631 passes through baffle 635; two auxiliary cylinders 634 are set on baffle 635 and located on both sides of main cylinder 632 respectively, and one end of auxiliary push rod 633 is connected in each auxiliary cylinder 634, and the other end of each auxiliary push rod 633 is connected to connecting plate 636; main cylinder 632 drives main push rod 631 to push and pull box door 4, and drives two auxiliary push rods 633 to push and pull in auxiliary cylinder 634.

[0049] like Figure 4 , Figure 5As shown, in a preferred embodiment of this invention, the treatment box further includes a winch motor 7, a rope, and a pulley 8. The winch motor 7 and the pulley 8 are located on the top of the water tank 1. One end of the rope is connected to the winch motor 7, the main body of the rope is wound around the pulley 8, and the other end of the rope is connected to the box door 4. In this preferred embodiment, the winch motor 7 and the pulley 8 are located on the top of the water tank 1. The rope on the winch motor 7 is wound around the pulley 8, and the end of the rope is connected to the top of the box door 4, thereby realizing the electric control of the opening and closing of the box door 4.

[0050] Under normal circumstances, the door 4 is open. When it is necessary to close the door 4, the main push rod 631 on the push-pull element 63 pushes the door 4 horizontally outward. The auxiliary push rod 633 prevents the door 4 from rotating and provides additional pushing force. The winch motor 7 loosens the rope to lower the door 4. When the door 4 is in position, the winch motor 7 stops, and the main push rod 631 pulls the door 4 horizontally inward, locking the door 4 onto the opening 21 of the battery compartment 2. When it is necessary to open the door 4, the main push rod 631 on the push-pull element 63 pushes the door 4 horizontally outward. The auxiliary push rod 633 prevents the door 4 from rotating and provides additional pushing force. The winch motor 7 tightens the rope to pull the door 4 upward. When the door 4 is in position, the winch motor 7 stops, and the electric push rod pulls the door 4 horizontally inward, locking the door 4 onto the front side of the water tank 1. In this context, "door 4 in position" means that the folded edge 41 of door 4 abuts against the top surface of the outer side of the battery container 2 or water tank 1. After an abnormal battery is placed in the battery container 2, door 4 is closed. Once the smoke and temperature detector 25 detects that the abnormal battery is burning, the water inlet solenoid valve opens, and water from water tank 1 enters the battery container 2 to cool it down and prevent the abnormal battery from overheating and exploding. After the abnormal battery has burned out, door 4 is opened again to remove the battery.

[0051] As a preferred embodiment of this invention, in the disposal box of the present invention, a fireproof sealing layer is provided on the surface of the box door 4 facing the opening 21. The fireproof sealing layer can be either coated with a ring of fireproof material at the edge corresponding to the opening 21, or coated with a layer of fireproof material on the inner surface of the box door 4, so that the box door 4 can be both fireproof and sealed.

[0052] like Figure 7As shown, in a preferred embodiment of this invention, the battery container 2's walls and door 4 both comprise inner and outer steel plates 42, and a sandwich layer 43 between the two steel plates 42, with fire-resistant material in the sandwich layer 43. In this preferred embodiment, both the battery container 2 and the door 4 are 30 mm thick, with inner and outer steel plates 42 each 3 mm thick, and a sandwich layer 43 between the two steel plates 42. The sandwich layer 43 is filled with fire-resistant material, whose fire resistance time is greater than the burning time of a single battery, thereby effectively reducing the possibility of battery explosion.

[0053] like Figure 1 and Figure 2 As shown in the preferred embodiment of this invention, the battery housing 2 in the disposal box of the present invention is provided with a built-in charging device 23. The built-in charging device 23 is located at the bottom of the battery housing 2 and is used to fix the battery and charge the battery. The battery housing 2 is also provided with an inlet connector, which is connected to the built-in charging device 23. The inlet connector contains fire-retardant material and has fire-retardant properties, thereby preventing flames or sparks generated by abnormal battery high temperature from burning to the outside of the disposal box along the line, thus improving safety performance.

[0054] like Figure 2 As shown in the preferred embodiment of this invention, a smoke detector 24 and a temperature detector 25 are installed on the top surface inside the battery housing 2 in the disposal box of this invention. Through the smoke detector 24 and temperature detector 25 in this preferred embodiment, staff can be promptly alerted to the combustion status of abnormal batteries and warnings can be issued for high-temperature hazards, thereby preventing the abnormal batteries from exploding.
