Technical Field
[0001] The present application relates to the field of charging energy storage, and in particular to a stacked charging energy storage system. Background Art
[0002] A charging energy storage system is a type of power storage device that is commonly used to store mains electricity, photovoltaic power, and generator power, thereby providing power to various electrical equipment to maintain life and production when the power supply system fails.
[0003] In existing technologies, charging energy storage systems include an inverter unit and an energy storage unit. The inverter unit is used to convert direct current (DC) into alternating current (AC). Multiple energy storage units are stacked vertically, with adjacent units connected by vertically positioned latches. This allows the number of energy storage units to be adjusted to meet actual needs.
[0004] Regarding the above-mentioned related technologies, when disassembling the energy storage unit, the energy storage unit needs to be lifted vertically to a large height before the latch can be disengaged from another adjacent energy storage unit and the energy storage unit can be disassembled, which is relatively inconvenient. Summary of the Invention
[0005] In order to facilitate the disassembly of the energy storage unit, the present application provides a stacked charging energy storage system.
[0006] The stacked charging energy storage system provided in this application adopts the following technical solution:
[0007] A stacked charging energy storage system includes a plurality of energy storage units, wherein the plurality of energy storage units are distributed in a vertical direction, the bottom of each energy storage unit is provided with a positioning hole, and the top of each energy storage unit is provided with a positioning pin, wherein the positioning pin of one energy storage unit is plugged into the positioning hole of another adjacent energy storage unit;
[0008] The positioning pin includes a mounting slide, a positioning neck ring and a positioning slider. The mounting slide is installed on the energy storage unit, the positioning neck ring is installed on the mounting slide, the positioning neck ring is protruding from the surface of the energy storage unit, the outer peripheral surface of the positioning neck ring is vertically arranged, the positioning slider slides in the vertical direction to cooperate with the mounting slide, an elastic part is installed between the positioning slider and the mounting slide, the top outer peripheral surface of the positioning slider is provided with a slider inclined surface, and the slider inclined surface is protruding from the positioning neck ring.
[0009] By adopting the above technical solution, when removing the energy storage unit, the unit is lifted a certain distance to disengage the locating collar from the locating socket. The unit can then be moved horizontally to the dismantling personnel. When the energy storage unit is moved horizontally, the inner wall of the locating socket fits tightly against the inclined surface of the slider, causing the locating slider to retract vertically into the mounting slide. This allows for quick and convenient dismantling without having to lift the unit a great distance, which helps reduce the physical exertion of the dismantling personnel.
[0010] Optionally, the mounting slide is provided with a contraction groove, the positioning slider slides in the vertical direction to fit in the contraction groove, and a deflection gap is provided between the bottom of the positioning slider and the inner wall of the contraction groove;
[0011] The inner wall of the positioning neck ring is provided with a neck ring slope, and the neck ring slope is inclined from top to bottom in a direction away from the positioning neck ring axis. The slider slope is inclined from top to bottom in a direction away from the positioning slider axis, and the bottom of the slider slope abuts against the neck ring slope.
[0012] By adopting the above technical solution, when the energy storage unit is not removed, the inclined surface of the slider is tightly fitted against the inclined surface of the neck ring under the action of the elastic member, making the positioning slider less likely to shake, which is conducive to ensuring the connection stability of the two adjacent energy storage units.
[0013] When removing the energy storage unit, the energy storage unit moves in the horizontal direction and the positioning slider shrinks in the vertical direction into the mounting slide, so that the lower inclined surface of the slider moves away from the inclined surface of the neck ring, and the positioning slider can swing through the deflection gap between it and the inner wall of the shrinkage groove, so that the positioning slider is not easy to hinder the horizontal movement and disassembly of the energy storage unit, thereby reducing the difficulty of disassembling the energy storage unit.
[0014] Optionally, the elastic member is a linear spring, both ends of the elastic member are respectively mounted on the positioning slider and the mounting slide, and the elastic member is arranged in a vertical direction.
[0015] The above technical solution is adopted to ensure that when the energy storage unit is not removed, the inclined surface of the slider is always tightly fitted against the inclined surface of the neck ring under the action of the elastic member, thereby ensuring the connection stability of the two adjacent energy storage units.
[0016] Optionally, the positioning slider is rigid.
[0017] By adopting the above technical solution, it is helpful to ensure that when the energy storage unit is not removed, the inclined surface of the slider is always tightly fitted against the inner wall of the positioning hole under the action of the elastic member, thereby ensuring the connection stability of the two adjacent energy storage units.
[0018] Optionally, the positioning socket includes a neck ring socket and a slider socket, the inner wall of the neck ring socket is vertically arranged, and the inner wall of the slider socket is inclined.
[0019] By adopting this technical solution, when removing an energy storage unit, the disassembler only needs to lift the unit until the neck ring socket is free of the positioning collar, and then move the unit horizontally to the disassembler's side. Furthermore, when the energy storage unit is not removed, the vertically arranged inner wall of the slider socket prevents the positioning pin from disengaging from the socket, thus ensuring the stability of the connection between two adjacent energy storage units.
[0020] Optionally, the top corners of the positioning collar are chamfered.
[0021] By adopting the above technical solution, it is easy to disassemble and assemble two adjacent energy storage units, and the wear of the top corners of the positioning neck ring is reduced.
[0022] Optionally, the stacked charging energy storage system further includes a mounting base, and the plurality of energy storage units are mounted on top of the mounting base, and the mounting base is rotatably coupled with a pulley.
[0023] By adopting the above technical solution, it is convenient for dismantling personnel to push the energy storage unit to a position convenient for dismantling through the pulley.
[0024] Optionally, the mounting base is provided with lifting legs, and the lifting legs are telescopically arranged in a vertical direction.
[0025] By adopting the above technical solution, when using the stacked charging energy storage system, the lifting legs are extended and tightly fitted against the bearing surface, so that the stacked charging energy storage system can be stably placed on the ground.
[0026] Optionally, the energy storage unit is provided with a unit handle, and the unit handle is located on the outer peripheral surface of the energy storage unit.

When the energy storage unit is moved horizontally, the inner wall of the positioning socket fits tightly against the inclined surface of the slider, and the positioning slider is retracted vertically into the mounting slide. This allows for dismantling without having to lift the energy storage unit to a great height, which is convenient and quick, and helps reduce the physical exertion of the dismantling personnel.
[0030] 2. When the energy storage unit is not removed, the slider's inclined surface is tightly fitted to the neck ring's inclined surface under the action of the elastic member, making the positioning slider less likely to shake, which is conducive to ensuring the connection stability of the two adjacent energy storage units;
[0031] When removing the energy storage unit, the energy storage unit moves in the horizontal direction and the positioning slider shrinks in the vertical direction into the mounting slide, so that the lower inclined surface of the slider moves away from the inclined surface of the neck ring, and the positioning slider can swing through the deflection gap between it and the inner wall of the shrinkage groove, so that the positioning slider is not easy to hinder the horizontal movement and disassembly of the energy storage unit, thereby reducing the difficulty of disassembling the energy storage unit.

[0038] The following is combined with Figure 1-5 This application is described in further detail.
[0039] The embodiment of the present application discloses a stacked charging energy storage system. Figure 1 and Figure 2 The stacked charging energy storage system includes an installation base 1, an energy storage unit 2 and an inverter unit 3. There are two energy storage units 2. The installation base 1, the two energy storage units 2 and the inverter unit 3 are distributed from bottom to top.
[0040] Reference Figure 3The bottom of the mounting base 1 is rotatably engaged with four pulleys 11, and the four pulleys 11 are distributed in a rectangular shape, so that the dismantling personnel can move the stacked charging energy storage system. Four lifting legs 12 are also installed at the bottom of the mounting base 1, and the four lifting legs 12 are distributed in a rectangular shape. The lifting legs 12 are telescopically arranged in the vertical direction, so that during the use of the stacked charging energy storage system, the stacked charging energy storage system can be supported by extending the lifting legs 12. Specifically, in an embodiment of the present application, the lifting legs 12 are threadedly engaged with the mounting base 1, and the lifting legs 12 are arranged in the vertical direction, so that the length of the lifting legs 12 can be adjusted by rotating the lifting legs 12.
[0041] Reference Figure 2 and Figure 3 The top of the energy storage unit 2 is provided with six positioning pins 4, and the bottom of the energy storage unit 2 is provided with six positioning sockets 201. The positioning pins 4 of one energy storage unit 2 are respectively plugged into and matched with the positioning sockets 201 of another adjacent energy storage unit 2 to ensure the connection stability of the two adjacent energy storage units 2. In addition, the energy storage unit 2 is fixedly mounted with a unit handle 21. The unit handle 21 is located on the outer surface of the energy storage unit 2, so that the dismantling personnel can apply force to lift the energy storage unit 2 through the unit handle 21.
[0042] Reference Figure 5 The positioning socket 201 includes a neck ring socket 202 and a slider socket 203. The neck ring socket 202 is located at the bottom of the slider socket 203. The inner wall of the neck ring socket 202 is vertically arranged and is cylindrical. The inner wall of the slider socket 203 is inclined and is truncated.
[0043] Reference Figure 4 and Figure 5 The positioning pin 4 includes a mounting slide 41, a positioning neck ring 42 and a positioning slider 43. The mounting slide 41 is fixedly mounted on the top of the energy storage unit 2, and the positioning neck ring 42 is fixedly mounted on the top of the mounting slide 41. The top of the mounting slide 41 and the positioning neck ring 42 are both protruding from the top surface of the energy storage unit 2, and the top of the mounting slide 41 and the positioning neck ring 42 are both plugged into the neck ring socket 202, and the top outer peripheral surface of the mounting slide 41 and the outer peripheral surface of the positioning neck ring 42 are both vertically arranged to ensure the connection stability of the two adjacent energy storage units 2. In addition, the top corners of the positioning neck ring 42 are chamfered to reduce the occurrence of collision and wear between the positioning neck ring 42 and the inner wall of the neck ring socket 202.
[0044] Reference Figure 5The mounting slide 41 is provided with a contraction groove 401, and the positioning collar 42 is provided with a positioning groove 402, which is connected to the contraction groove 401. The inner wall of the positioning groove 402 is provided with a collar bevel 421, which is closed end to end and tilted from top to bottom in a direction away from the axis of the positioning collar 42. The collar bevel 421 makes the positioning groove 402 have a frustum shape.
[0045] The positioning slider 43 is rigid and slides vertically within the contraction groove 401. A deflection gap 403 is defined between the bottom of the positioning slider 43 and the inner wall of the contraction groove 401. The top of the positioning slider 43 protrudes from the positioning collar 42 and engages with the slider receptacle 203, ensuring a stable connection between two adjacent energy storage units 2. The top outer surface of the positioning slider 43 is provided with a slider slope 431, which protrudes from the positioning collar 42 and is arranged end-to-end. This closed arrangement of the slider slope 431 is slanted downward, away from the axis of the positioning slider 43. Furthermore, the slider slope 431 gives the positioning slider 43 a frustum-shaped configuration. This facilitates disassembly by allowing the top energy storage unit 2 to press horizontally against the slider slope 431, pressing the positioning slider 43 into the contraction groove 401, thereby reducing the lifting height of the energy storage unit 2.
[0046] The bottom of the slider slope 431 of the positioning slider 43 abuts against the neck ring slope 421. An elastic member 44 is installed between the positioning slider 43 and the mounting slide 41, so that the slider slope 431 is normally kept in a tight fit against the neck ring slope 421. Specifically, in the embodiment of the present application, the elastic member 44 is a linear spring, with its ends fixedly mounted to the positioning slider 43 and the mounting slide 41, respectively, and the elastic member 44 is arranged in the vertical direction.
[0047] The stacked charging energy storage system of the present embodiment is implemented as follows: When removing the energy storage unit 2, the unit is lifted a certain distance so that the positioning collar 42 disengages from the positioning socket 201. The unit can then be moved horizontally to the dismantling personnel. When the unit 2 is moved horizontally, the inner wall of the positioning socket 201 fits tightly against the inclined surface 431 of the slider, causing the positioning slider 43 to retract vertically into the mounting slide 41. This allows for quick and convenient dismantling without having to lift the unit 2 to a great height, which helps reduce the physical exertion of the dismantling personnel.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
