[0002] Traditional steel mills use diesel locomotives to transport molten iron and steel. Due to the long waiting time, preheating is required for each start. Frequent starts and standby waiting result in high energy consumption and loud noise. Electric locomotives can basically achieve zero power consumption in standby mode, with short starting time and low noise. Electric locomotives generally use lithium batteries as energy.

A battery pack 3 is installed in the battery box 2, and the battery pack 3 is composed of a plurality of unit batteries connected in series. A prompt component 4 is installed above the battery pack 3. The battery box 2 is composed of a heat-insulating outer shell 21 and a heat-conducting inner shell 22. The heat-insulating outer shell 21 can avoid the introduction of heat from the external high-temperature environment, and the heat-conducting inner shell 22 is conducive to heat transfer. A coolant filling cavity 5 is provided between the heat-insulating outer shell 21 and the heat-conducting inner shell 22. The coolant filling cavity 5 is filled with coolant to absorb the heat generated by the lithium battery. The battery box 2 is connected to a sealing cover 6 by bolts;

[0026] The prompt component 4 includes a grid plate 41 attached to the upper surface of the battery pack 3. The grid plate 41 can reduce the impact on heat transfer. The four corners of the top of the grid plate 41 are fixedly connected with movable rods 42. A positioning sleeve 43 is fixed at a position corresponding to the movable rod 42 on the battery box 2. The positioning sleeve 43 penetrates the battery box 2, and the top of the movable rod 42 extends into the positioning sleeve 43. The upper end surface of the positioning sleeve 43 and the upper end surface of the movable rod 42 are on the same horizontal plane. A spring 44 is sleeved on the movable rod 42. After the battery pack 3 is bulged, the grid plate 41 and the movable rod 42 will move up, which can make the staff find it, so as to facilitate timely maintenance or replacement of the lithium battery.

[0027] Specifically, a liquid injection connector 7 is fixedly connected to the top of the battery box 2 , and the bottom end of the liquid injection connector 7 extends into the coolant filling cavity 5 .

[0028] Furthermore, the bottom end of the liquid injection joint 7 is connected to a liquid equalizing tube 8, and the liquid equalizing tube 8 is arranged in the coolant filling chamber 5. An overflow groove 9 is provided on the upper side of the liquid equalizing tube 8. After the coolant is introduced into the liquid equalizing tube 8, it is evenly distributed. The liquid level will flow out only when it reaches the overflow groove 9, so that the coolant is evenly distributed.

[0034] Working principle and process:

[0035] The blistering phenomenon that occurs during the use of the battery pack 3 will cause the thickness to increase, thereby causing the position of the grid plate 41 to move up, thereby causing the movable rod 42 to move up in the positioning sleeve 43, so that the upper end surface of the movable rod 42 extends, so that the staff can find it in time, so that the lithium battery can be repaired or replaced in time. The battery box 2 is composed of a heat-insulating outer shell 21 and a heat-conducting inner shell 22 to reduce the external heat introduced into the interior, and coolant is injected into the coolant filling cavity 5 therebetween to absorb the heat generated by the battery pack 3 when it is working, so as to avoid overheating of the battery pack 3. The coolant is introduced into the equalizing tube 8 through the filling joint 7, and the liquid level will flow out only when it reaches the overflow groove 9, so that the coolant flows evenly during injection, and the coolant that absorbs enough heat is discharged from the drain interface 10, and new coolant can be replaced.
