Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model.

[0017] like Figures 1 to 5 The device shown is a high-power mobile energy storage system cable storage device, installed inside the lower part of an energy storage container. It includes a storage slot 1, in which a cable 2 is installed. A cable outlet 3 is provided on one side of the storage slot 1. One end of the cable 2 is movably locked in the cable outlet 3, and the other end is fixedly installed in the top of the storage slot 1 near the cable outlet 3 and connected to the inside of the energy storage container. Inside the storage slot 1, two sets of positioning pulleys are respectively provided at both ends of the cable 2. At least two sets of movable guide wheels 4 are also provided at the top and bottom of the storage slot 1 along the direction of the cable 2 to ensure that the position of the cable 2 can move freely during the pulling out or retraction process. A hose suspension device 5 is also installed on the side wall of the storage slot 1 away from the cable outlet 3. The suspension end of the hose suspension device 5 is connected to the cable 2. The two ends of the cable 2 are folded in a U-shape inside the storage slot 1 through the positioning pulleys, the hose suspension device 5, and the movable guide wheels 4.

[0018] The hose suspension device 5 uses a disc-type cable puller inside, which can be extended to 2-3 meters and can be locked at any position. The cable puller can be pulled with a pulling force of 20-30N, making it easy to pull the cable 2. When the cable 2 is fixed to the load equipment, the hose suspension device 5 is locked in the corresponding position by means of the connection fixing force. When the cable 2 is stored, the fixing force is removed at the equipment end, and the hose suspension device 5 can be automatically retracted. The operation of pulling out or retracting the cable 2 is convenient.

[0019] The positioning pulleys include a first positioning pulley 6 located at the cable outlet 3 of the storage slot 1 and a second positioning pulley 7 located at the fixed end of the cable 2. The cable 2 is wrapped around the outside of the first positioning pulley 6 and the second positioning pulley 7. The second positioning pulley 7 is mounted on the top of the storage slot 1 via a mounting base 8. The second positioning pulley 7 and the mounting base 8 are rotatably mounted. Similarly, the first positioning pulley 6 is mounted on the bottom of the storage slot 1 via a mounting base 8. The second positioning pulley 7 and the mounting base 8 are rotatably mounted to ensure that the position of the cable 2 is fixed, while avoiding excessive instantaneous tension that could damage the connection between the cable and the power supply equipment of the energy storage container.

[0020] A retaining ring 9 is also fitted on the outer wall of the cable 2 outside the storage groove 1. The outer diameter of the retaining ring 9 is larger than the inner diameter of the cable outlet 3, so that the cable 2 can be fixed in place when not in use.

[0021] The suspension end of the hose suspension device 5 is also connected to a tension seat 10. A reversing wheel 11 is rotatably installed inside the tension seat 10. The inner side of the cable 2 is bent and rolled in contact with the reversing wheel 11.

[0022] The top and bottom of the storage slot 1 are each provided with two sets of parallel guide rails 12 along the direction of the cable 2. The movable guide wheels 4 are all movably mounted on the guide rails 12 via sliding seats 13.

[0023] Both the mounting base 8 and the sliding base 13 on which the first positioning pulley 6 is installed are equipped with a corresponding rotatable limit pulley 14. The cable 2 is movably disposed between the first positioning pulley 6, the movable guide wheel 4 and the limit pulley 14.

[0024] The mounting base 8 for installing the first positioning pulley 6 and the inner side of the sliding base 13 are both vertically provided with an adjustment groove 16 at the two ends of the pivot 15 of the limiting pulley 14. A movable block 17 is slidably arranged in the adjustment groove 16. The two ends of the pivot 15 of the limiting pulley 14 are rotatably arranged with the movable block 17. A buffer spring 18 is provided in the adjustment groove 16 on the side near the upper and lower walls of the storage groove 1. One end of the buffer spring 18 abuts against the movable block 17.

[0025] Both sets of guide rails 12 have a return groove 19, and each sliding seat 13 is provided with a return block 20 that moves along the inside of the return groove 19. A return spring 21 is provided between adjacent return blocks 20 and between the return block 20 near the cable outlet 3 and the return groove 19. The return spring 21 can automatically pull back the cable 2 when it is being stored. At the same time, the movable guide wheel 4 on the sliding seat 13 can play a good guiding and limiting role.

[0026] A recess 22 is provided on the side wall of the storage slot 1 near the cable outlet 3 to reduce the protrusion of the cable 2 and provide a certain degree of external shielding for the cable 2 when not in use.

[0027] This utility model realizes the convenience of storing and using MW-level high-power power supply cable 2 in a small space. This storage device utilizes the vertical and horizontal distribution in a narrow space to expand the space application. The upper part of the device uses a second positioning pulley 7 plus two sets of movable guide wheels 4 to suspend the cable 2 through the guide rail 12. The bottom uses a first positioning pulley 6 plus two sets of movable guide wheels 4 to guide the cable 2 through the guide rail 12. The opposite side of the cable outlet 3 uses a rubber tube suspension device 5 to tighten the cable 2. This realizes the regular storage of the cable 2 in a narrow space. At the same time, the cable 2 is easy to pull out and retract during the application process, and the friction and wear of the cable 2 during the stretching process are small.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
