Description

Technical Field

[0001] The invention belongs to the technical field of battery packs, and in particular relates to an industrial energy storage battery pack. Background Art

[0002] Most industrial energy storage batteries are flow batteries, a new type of storage battery. Liquid flow batteries are high-performance batteries that separate the positive and negative electrolytes and circulate them separately. They have the characteristics of high capacity, wide application range, and long cycle life. They are currently a new energy product. Existing energy storage batteries used in industrial production, during operation, in order to ensure the power supply effect, mostly use multiple batteries in series to implement centralized power supply operations.

[0003] In order to ensure the safety and stability of the battery pack, an isolation cover is generally set up to place the batteries inside the cover to form a battery pack. However, when one of the battery cells in the battery pack fails, the entire cover needs to be disassembled, and the failed battery needs to be disconnected from the circuit, which makes the battery maintenance work very troublesome. In addition, the existence of the cover isolates the battery pack from the outside world as a whole. Heat is generally dissipated through a liquid cooling radiator, which cannot be completely in contact with the battery. Most of the heat is dissipated by heat exchange through air as a heat transfer medium, and the heat exchange efficiency of air is low, resulting in poor heat dissipation of the battery pack as a whole. Summary of the invention

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The embodiment of the present invention provides an industrial energy storage battery pack, such as Figure 1-5As shown, it includes a placement rack 1 and a bracket 2, a battery body 3 is placed on the top of the bracket 2, a placement groove is provided on the front side of the bracket 2, the bracket 2 is slidably embedded in the placement groove of the placement rack 1, a pulley 4 is rotatably installed at the bottom of the bracket 2, the bracket 2 and the battery body 3 are equidistantly distributed along the horizontal direction of the placement rack 1, a positioning frame 5 is sleeved on the outside of the battery body 3, and a limiting plate 10 is installed on the lower side of the two side walls of the positioning frame 5, a limiting groove matched with the limiting plate 10 is provided on the upper surface of the bracket 2, and positioning bars 6 are installed on the left and right sides of the positioning frame 5, and the positioning bars 6 are provided in four groups and are equidistantly distributed, and the inner side wall of the placement groove of the placement rack 1 is provided with a positioning groove matched with the width of the positioning bar 6, and the placement rack 1 A groove is provided at the lower part of the front side, and a spring 7 is installed in the groove. A gasket 8 is connected to the movable end of the spring 7. The gasket 8 is slidably embedded in the groove of the placement rack 1. A card block 9 is installed on the side of the gasket 8 away from the spring 7. The card block 9 extends to the inner side of the placement groove of the placement rack 1. A card groove adapted to the card block 9 is provided on the side of the bracket 2. A push block is installed on the front side of the gasket 8, and the push block is located on the outer side of the placement rack 1. Five groups of card blocks 9 are provided, and the five groups of card blocks 9 are located on the sides of the five groups of brackets 2 in a one-to-one correspondence. A through groove 11 is provided on the side wall of the placement groove of the placement rack 1. A liquid tank 12 and a driving pump 13 are installed on the top of the placement rack 1. The water inlet of the driving pump 13 is connected to the liquid tank 12, and the outlet of the driving pump 13 is connected to the water tank 12. The water inlet is connected to the through slot 11 of the placement rack 1 through a pipe. The device places the battery body 3 above the bracket 2. When one of the battery bodies 3 of the battery pack needs to be repaired or replaced, the push block on the front side of the placement rack 1 is first pushed to push the card block 9 out of the card slot on the side of the bracket 2. Then the bracket 2 with the damaged battery can be pulled out, and the bracket 2 can be easily slid out with the assistance of the pulley 4. This installation method can make the removal of the battery more convenient and labor-saving. After the battery is taken out, the positioning frame 5 can be pulled upward to make the limit plate 10 separate from the bracket 2. At this time, the positioning frame 5 can be removed to expose the battery surface for maintenance work. When the battery maintenance is completed, the positioning frame 5 can be removed. The frame 5 is reinstalled and the bracket 2 is pushed into the placement rack 1. At this time, the positioning strip 6 on the side of the positioning frame 5 can be slowly pushed in along the positioning groove of the placement rack 1. When the battery is fully pushed in, the block 9 is clamped into the groove on the side of the bracket 2 under the elastic force of the spring 7, so that the bracket 2 can be limited and fixed. The device can position and place the battery body 3 through the bracket 2 and the positioning frame 5, and the bracket 2 can be limited and fixed through the cooperation of the spring 7 and the block 9. This installation method can make the disassembly and assembly of the battery body 3 more convenient and labor-saving. When the battery pack is working, the driving pump 13 is started to transport the coolant in the liquid tank 12 to the through groove 11 of the placement rack 1, so as to dissipate the heat of the battery pack.

[0027] The left and right side walls of the positioning frame 5 and the positioning bar 6 are all made of copper. Thermal conductive silicone grease is applied between the battery body 3 and the positioning frame 5. The positioning frame 5 can not only position and install the battery body 3, but also absorb the heat generated by the battery body 3 during operation and transfer it to the positioning bar 6. The positioning bar 6 fits tightly with the positioning groove on the side of the placement rack 1. When the coolant flows in the through groove 11, the heat can be quickly absorbed, thereby improving the heat dissipation effect of the battery body 3.

[0028] The through grooves 11 are distributed in an S shape on the side wall of the placement rack 1, and a closed circulation loop is formed between the through grooves 11, the liquid tank 12 and the driving pump 13. The S-shaped distribution of the through grooves 11 can realize the circulation flow of the coolant, and on the other hand, it can be evenly distributed on the surface of the positioning frame 5, thereby improving the heat transfer efficiency of the coolant.

[0029] A conductive slot 14 is installed on the rear side of the battery body 3, a slot is opened on the rear side of the placement rack 1, and a conductive bar 15 is inserted in the slot. The conductive bar 15 is set to be elliptical and fixed to the back of the placement rack 1 by bolts 16. By setting the conductive bar 15, the battery bodies 3 are connected to the conductive slot 14 by wires through the conductive bar 15. When the battery body 3 is pulled out, the conductive slot 14 is separated from the conductive bar 15, thereby disconnecting the battery body 3. Similarly, when the battery body 3 is installed, the conductive slot 14 is tightly plugged with the conductive bar 15, thereby realizing the power-on of the battery body 3. The conductive bar 15 can make it possible to disconnect the circuit separately when the battery is disassembled and assembled, thereby further improving the convenience of disassembly and assembly of the battery body 3.

[0030] There are four groups of conductive bars 15, and the four groups of conductive bars 15 are distributed among the five groups of battery bodies 3. The four groups of conductive bars 15 connect the five groups of battery bodies 3 in series. When one of the battery bodies 3 is removed, the conductive bar 15 where it is located is in a disconnected state, so that the entire battery pack is in a power-off state, thereby improving the safety of battery pack maintenance.

[0031] A heat sink 17 is installed on the top of the liquid tank 12, and the heat sinks 17 are equidistantly distributed in the horizontal direction of the upper surface of the liquid tank 12. A fan 18 is installed on the top of the liquid tank 12, and the fan 18 is installed on the side of the heat sink 17. By providing the heat sink 17 and the fan 18, when the coolant is used for a long time, the temperature will rise. At this time, the surface temperature of the liquid tank 12 rises, and the heat of the liquid tank 12 is absorbed by the heat sink 17, and the air flow speed near the heat sink 17 is accelerated by the fan 18, so that the heat of the liquid tank 12 can be quickly dissipated, thereby ensuring the normal use of the coolant for a long time.

[0032] A heat dissipation groove 19 is opened on the front side of the positioning frame 5, and the heat dissipation grooves 19 are evenly distributed in the vertical direction of the front surface of the positioning frame 5. By opening the heat dissipation grooves 19 on the front side of the positioning frame 5, the external flowing air can contact the front side of the battery body 3, thereby further improving the heat dissipation effect of the battery body 3.

[0033] A universal wheel 20 is separately installed on the bottom rear side of the bracket 2. By providing the universal wheel 20, the universal wheel 20 is separately installed on the bottom rear side of the bracket 2. This arrangement can make the bracket 2 more flexible when moving, and facilitate the movement of the battery body 3.
