The energy storage unit of the traditional railway locomotive and solar power generation energy storage system uses lead-acid batteries. The energy storage efficiency of lead-acid batteries is only about 80% at most, while the energy efficiency of lithium batteries used as energy storage devices can reach 90%. Not only that, the charge and discharge life of lithium batteries is much longer than that of traditional lead-acid batteries.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The present invention provides a technical solution: Figures 1 to 8 As shown, in this embodiment, a locomotive lithium battery installation structure includes a storage box 1, one side of the storage box 1 is rotatably installed with a cover 2, a U-shaped storage rack 3 is slidably installed inside the storage box 1, and clamps 4 are symmetrically slidably installed on both sides of the U-shaped storage rack 3, and a tray 5 is slidably installed at the bottom of the U-shaped storage rack 3. The clamps 4 move with the lifting of the tray 5, and the two clamps 4 can clamp and fix the lithium battery, and a positioning frame 6 is slidably installed on the top of the storage box 1, and corner blocks 7 are symmetrically fixedly installed at the bottom four corners of the positioning frame 6. The corner blocks 7 are used to limit the corner position of the lithium battery, and the U-shaped storage rack 3 is cancelled by driving the positioning frame 6 and the corner blocks 7 to rise. After positioning, the U-shaped storage rack 3 is slid out of the interior of the storage box 1, and the lithium battery is placed in the middle of the tray 5. The gravity squeeze of the lithium battery on the tray 5 will drive the tray 5 to slide down. At the same time, the clamping plate 4 will be synchronously driven to move, and the two clamping plates 4 will approach each other and squeeze the lithium battery, which is used to squeeze and fix the position of the lithium battery, and can position the position of the lithium battery to improve the stability of the lithium battery. Then, the U-shaped storage rack 3 is slid into the interior of the storage box 1, and the positioning rack 6 is controlled to descend, which will drive the four top corner blocks 7 to be stuck in the four corners of the lithium battery for fixing the position of the lithium battery. The lithium battery can be stably stored in the tray 5 through the four top corner blocks 7 to prevent the lithium battery from slipping out of the tray 5, thereby improving the safety of the lithium battery.

[0027] like Figures 1 to 8 As shown, guide rods 8 are symmetrically fixedly installed on the inner walls on both sides and the inner wall on the bottom of the storage box 1, sliding seats are symmetrically fixedly installed on both sides and the bottom of the storage box 1, and the U-shaped storage rack 3 is slidably installed between the six guide rods 8 through the sliding seats.

[0028] The U-shaped storage rack 3 is slid along the six guide rods 8 , so that the U-shaped storage rack 3 can be stably slid out of or into the storage box 1 , so as to limit the movement of the U-shaped storage rack 3 .

[0029] like Figures 1 to 8 As shown, a first hydraulic rod 9 is fixedly installed at the bottom of the U-shaped storage rack 3, and the moving end of the first hydraulic rod 9 passes through the U-shaped storage rack 3 and is fixedly connected to the middle part of the tray 5. First sliding holes 10 are symmetrically opened on both sides of the U-shaped storage rack 3, and a first sliding rod 11 is slidably installed inside the first sliding hole 10. The clamping plate 4 is fixedly installed between one end of four first sliding rods 11, and a connecting plate 12 is fixedly installed between the ends of the four first sliding rods 11 away from the clamping plate 4. Second hydraulic rods 13 are symmetrically fixedly installed on both sides of the U-shaped storage rack 3, and the moving end of the second hydraulic rod 13 is fixedly connected to the middle part of the connecting plate 12. The oil outlet end and the oil inlet end of the first hydraulic rod 9 are connected to the oil inlet end and the oil inlet end of the second hydraulic rod 13 through a pipeline, and the oil inlet and outlet amounts of the first hydraulic rod 9 are twice the oil inlet and outlet amounts of the second hydraulic rod 13.

[0030] When the lithium battery is placed in the middle of the tray 5, the gravity squeezing of the lithium battery on the tray 5 will drive the tray 5 to slide down, and the moving end of the first hydraulic rod 9 will be retracted into the interior of the first hydraulic rod 9. The hydraulic oil inside the first hydraulic rod 9 will be transported to the second hydraulic rod 13 through a pipeline, and the moving end of the second hydraulic rod 13 will be retracted into the interior of the second hydraulic rod 13, which will drive the connecting plate 12 connected to the moving end of the second hydraulic rod 13 to move, and the connection of the first sliding rod 11 will drive the clamping plate 4 to move, and then drive the two clamping plates 4 to approach each other and squeeze the lithium battery, which is used to squeeze and fix the position of the lithium battery. When the lithium battery is installed, the two clamping plates 4 can be automatically driven to squeeze the lithium battery, which is convenient for squeezing and fixing the lithium battery.

[0031] like Figures 1 to 8 As shown, a limiting hole 14 is symmetrically provided in the middle of the connecting plate 12, and a positioning rod 15 is slidably installed inside the limiting hole 14. A first extrusion spring 16 is sleeved on the outer side of one end of the positioning rod 15, and one end of the first extrusion spring 16 is fixedly connected to the side of the connecting plate 12 away from the first sliding rod 11, and the other end of the first extrusion spring 16 is fixedly connected to the outer side of the positioning rod 15. Positioning holes 17 are provided on both sides of the storage box 1 corresponding to the positions of the positioning rods 15, and the positioning holes 17 are slidably plugged with the positioning rods 15.

[0032] The U-shaped storage rack 3 is slid into the storage box 1 along the trajectory of the six guide rods 8 and when the U-shaped storage rack 3 moves to the final position, the positioning rod 15 is pushed by the first extrusion spring 16 to drive the positioning rod 15 to be inserted into the positioning hole 17, which is used to locate the position between the U-shaped storage rack 3 and the storage box 1 and to provide a stable connection between the U-shaped storage rack 3 and the storage box 1.

[0033] like Figures 1 to 8 As shown, a first extrusion slope 18 is provided at the end of the positioning rod 15, a push rod 19 is symmetrically slidably installed at one end of the connecting plate 12, a pull rod 20 is fixedly installed between one ends of the two push rods 19, and a second extrusion slope 21 is provided at the end of the push rod 19 away from the pull rod 20, and the second extrusion slope 21 is in extrusion contact with the first extrusion slope 18.

[0034] Pushing the pull rod 20 will drive the push rod 19 to move, and the second extrusion slope 21 on the push rod 19 will squeeze the first extrusion slope 18 at the end of the positioning rod 15, which will drive the positioning rod 15 to slide inside the limiting hole 14, so as to slide the positioning rod 15 out of the positioning hole 17, thereby facilitating the separation between the U-shaped storage rack 3 and the storage box 1.

[0035] like Figures 1 to 8 As shown, a fixing rod 22 is symmetrically fixedly installed on the top inner wall of the storage box 1, a through hole 23 is opened at the top of the positioning frame 6, and the through hole 23 is slidably connected to the fixing rod 22, and a second extrusion spring 24 is sleeved on the outer side of the top of the fixing rod 22, one end of the second extrusion spring 24 is fixedly connected to the top of the positioning frame 6, and the other end of the second extrusion spring 24 is fixedly connected to the top inner wall of the storage box 1.

[0036] After the U-shaped storage rack 3 is slid into the storage box 1, the second extrusion spring 24 squeezes the positioning rack 6 to drive the positioning rack 6 to slide down along the track of the fixing rod 22, thereby driving the four corner blocks 7 to be clamped at the four corners of the lithium battery.

[0037] like Figures 1 to 8 As shown, a rotating shaft 25 is rotatably mounted on the top inner wall of the storage box 1 through a bearing, a cam 26 is fixedly mounted in the middle of the rotating shaft 25, the cam 26 is in compression contact with the top inner wall of the positioning frame 6, and a knob 27 is rotatably mounted on the end of the rotating shaft 25.

[0038] By turning the knob 27 to drive the shaft 25 to rotate, the cam 26 in the middle of the shaft 25 will squeeze the top of the positioning frame 6, which will drive the positioning frame 6 to slide up along the trajectory of the fixing rod 22, and then drive the top corner block 7 to rise, so that the positioning of the lithium battery by the four top corner blocks 7 can be cancelled.

[0039] like Figures 1 to 8As shown, a second slide bar 28 is symmetrically fixedly installed at the bottom end of the tray 5, and a second slide hole 29 is symmetrically opened at the bottom end of the U-shaped storage rack 3. The second slide hole 29 is slidably connected to the second slide bar 28, and a return spring 30 is sleeved on the outer side of the bottom end of the second slide bar 28. One end of the return spring 30 is fixedly connected to the bottom end of the second slide bar 28, and the other end of the return spring 30 is fixedly connected to the bottom end of the U-shaped storage rack 3.

[0040] When the lithium battery is placed in the middle of the tray 5, the gravity squeezing of the lithium battery on the tray 5 will drive the tray 5 to slide down, and the second slide bar 28 at the bottom of the tray 5 will slide inside the second slide hole 29. At this time, the reset spring 30 is in an extended state. When the lithium battery is replaced later, the lithium battery is lifted up, and the lithium battery will cancel the gravity squeezing of the tray 5. The reset spring 30 will push the bottom end of the second slide bar 28 to drive the second slide bar 28 to slide up inside the second slide hole 29. The connection between the first hydraulic rod 9 and the second hydraulic rod 13 can synchronously drive the two clamps 4 to come into contact with each other, canceling the clamping and fixing of the lithium battery by the two clamps 4, and facilitating the subsequent installation of a new lithium battery.

[0041] The present invention provides a locomotive lithium battery installation structure, and the specific working principle is as follows:

[0042] When the device is in use, the rotating shaft 25 is driven to rotate by turning the knob 27, and the cam 26 in the middle of the rotating shaft 25 will squeeze the top of the positioning frame 6, and will drive the positioning frame 6 to slide and rise along the trajectory of the fixing rod 22, and then will drive the top corner block 7 to rise. At this time, the second extrusion spring 24 is in a compressed state, pushing the pull rod 20, which will drive the push rod 19 to move, and the second extrusion inclined surface 21 on the push rod 19 will squeeze the first extrusion inclined surface 18 at the end of the positioning rod 15, which will drive the positioning rod 15 to slide inside the limiting hole 14, so as to slide the positioning rod 15 out of the positioning hole 17. At this time, the first extrusion spring 16 is in an extruded state, and then the U-shaped storage rack 3 is slid out of the storage box 1 along the six guide rods 8, and then the lithium battery is placed on the bracket In the middle of the plate 5, the gravity squeezing of the tray 5 by the lithium battery will drive the tray 5 to slide down, the moving end of the first hydraulic rod 9 will be retracted into the inside of the first hydraulic rod 9, and the hydraulic oil inside the first hydraulic rod 9 will be transported to the second hydraulic rod 13 through the pipeline, and the moving end of the second hydraulic rod 13 will be retracted into the inside of the second hydraulic rod 13, which will drive the connecting plate 12 connected to the moving end of the second hydraulic rod 13 to move, and the connection of the first slide bar 11 will drive the clamping plate 4 to move, and then drive the two clamping plates 4 to approach each other and squeeze the lithium battery, which is used to squeeze and fix the position of the lithium battery. When the tray 5 descends, the second slide bar 28 at the bottom of the tray 5 will slide inside the second slide hole 29, and the return spring 30 is in an elongated state at this time;

[0043] Then, the U-shaped storage rack 3 is slid into the storage box 1 along the trajectory of the six guide rods 8. When the U-shaped storage rack 3 moves to the final position, the first extrusion spring 16 pushes the positioning rod 15 to drive the positioning rod 15 to be inserted into the positioning hole 17, so as to locate the position between the U-shaped storage rack 3 and the storage box 1.

[0044] Then, the knob 27 is turned to drive the shaft 25 to rotate, and the cam 26 in the middle of the shaft 25 is controlled to cancel the squeezing of the top of the positioning frame 6. The squeezing of the positioning frame 6 by the second squeezing spring 24 will drive the positioning frame 6 to slide down along the trajectory of the fixing rod 22, and then drive the four top corner blocks 7 to be stuck in the four corners of the lithium battery, so as to fix the position of the lithium battery.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
