[0033] An energy storage container includes a container body and energy storage units housed within the container body. The container body protects the energy storage units. The energy storage units store electrical energy. The energy storage units can be electrically connected to an external power source to supply power to that location.

Figure 2 yes Figure 1 A schematic structural view of another perspective of the structure shown. Figure 3 It is a schematic structural view of the wire winding system of the present invention. Figure 4 is Figure 3 A schematic structural view of another perspective of the structure shown. Figure 5 is Figure 3 A cross-sectional view of the structure shown.

[0036] Refer Figures 1 to 5 , this application provides an energy storage container, which includes: a box body, an energy storage unit and a wire winding system 100. An energy storage compartment and a wire winding compartment are provided in the box body. The energy storage unit is accommodated in the energy storage compartment for storing electric energy. The wire winding system 100 is accommodated in the wire winding compartment. The wire winding system 100 includes a wire winding shaft 120, a plurality of wire reels 130 and a plurality of cables (not shown in the figure). The wire winding shaft 120 is rotatably connected to the box body, and the wire winding shaft 120 is located in the wire winding compartment. The plurality of wire reels 130 are sleeved on the wire winding shaft 120 at intervals so as to be able to rotate following the wire winding shaft 120. A wire storage compartment 135 is formed between any two adjacent wire reels 130. The plurality of wire storage compartments 135 are used for winding and storing a plurality of cables. The wire reel 130 between the two wire reels 130 at both ends of the wire winding shaft 120 is an adjustable wire reel 132, and the adjustable wire reel 132 can move along the axial direction of the wire winding shaft 120 to adjust the axial distance between any two adjacent wire reels 130.

[0037] Before the energy storage container is used, the staff can adjust the axial distance between any two adjacent wire reels 130 according to the actual use requirements, so as to adjust the length dimension of the wire storage compartment 135, so that the staff can wind and unwind different numbers and different lengths of cables.

[0038] When the energy storage container is in use, the staff can unwind different cables according to the use requirements to supply power to multiple power consumption places respectively, improving the convenience of using the energy storage container. And it can avoid the problems of cable vacancy and waste, and reduce the use cost of the energy storage container.

[0039] In this embodiment, the energy storage container includes a box body (not shown in the figure). The box body includes a top plate, a bottom plate, and a front side plate, a rear side plate, a left side wall and a right side wall connected between the top plate and the bottom plate. The top plate, the bottom plate, the front side plate, the rear side plate, the left side wall and the right side wall enclose a working space for accommodating the energy storage unit and the wire winding system 100 to protect the energy storage unit and the wire winding system 100 and facilitate the transportation of the energy storage unit and the wire winding system 100.

[0040] A partition plate (not shown in the figure) can be provided in the energy storage container to divide the working space into at least two parts. The working space divided into at least two parts can include an energy storage compartment and a wire winding compartment. The energy storage compartment is used for accommodating the energy storage unit. The wire winding compartment is used for accommodating the wire winding system 100.

[0041] In some embodiments, the energy storage container may have multiple partitions extending vertically and / or horizontally to divide the workspace into multiple sections. Hydraulic chambers may also be included in the multiple sections of the workspace. The hydraulic chambers house a power source that is drive-connected to the cable reel system 100.

[0042] In other embodiments, the hydraulic compartment is located above the winding compartment, thereby effectively improving the space utilization of the energy storage container. Furthermore, the winding compartment and the hydraulic compartment are completely independent and uncoupled, facilitating the later inspection and maintenance of the winding system 100 and its power source.

[0043] Figure 6 This is a schematic diagram of the structure of the winding system of the present invention when an adjustable reel is set between two fixed reels.

[0044] See Figures 1 to 6 In this embodiment, the energy storage container includes a cable winding system. The cable winding system 100 includes a spool 120, multiple reels 130, and cables. The spool 120 is rotatably connected to the container body and is located within a cable winding compartment. The multiple reels 130 are spaced apart on the spool 120 to rotate with it. A winding compartment 135 is formed between any two adjacent reels 130. The multiple winding compartments 135 are used for winding and storing multiple cables.

[0045] In some embodiments, dustproof bearings are provided at both ends of the winding spool 120 so that the winding system 100 can be adapted to harsher sand and dust environments and extend the service life of the winding spool 120.

[0046] See Figures 1 to 6 In this embodiment, the plurality of reels 130 includes fixed reels 131 located at both ends of the winding shaft 120 and an adjustable reel 132 located between the two fixed reels 131. The fixed reels 131 are fixedly connected to both ends of the winding shaft 120. The adjustable reel 132 can move along the axial direction of the winding shaft 120 to adjust the spacing between any two adjacent reels 130, thereby adjusting the volume of the hopper 135. Operators can selectively adjust the number and volume of the hoppers 135 according to their needs to accommodate different quantities and lengths of cables, enabling the energy storage container to be specifically adapted to various application scenarios, improving the utilization efficiency of the energy storage container, avoiding cable control waste, and reducing the operating cost of the energy storage container.

[0047] In some embodiments, there may be one or more adjustable reels to adjust the number and volume of the reel 135 as needed, thereby enabling the energy storage container to be applied to application scenarios that require different numbers and lengths of cables, and the reel system 100 requires less technical expertise from the operators.

[0048] Figure 7 This is a partial cross-sectional view of the assembly of the winding spool and adjustable reel of the present invention. Figure 8 This is a schematic diagram of the adjustable reel of the present invention. Figure 9 This is a schematic diagram of the structure of the adjustable reel of the present invention after it is split into two half-reel structures.

[0049] See Figures 1 to 9 In this embodiment, the adjustable reel 132 is sleeved on the winding shaft 120, and the inner peripheral wall of the adjustable reel 132 is provided with a guide block 134.

[0050] The spool 120 is recessed with a guide channel 121 relative to the guide block 134, and the guide channel 121 extends axially along the spool 120. The guide block 134 is slidably accommodated within the guide channel 121 to adjust the axial length of the winding magazine 135, thereby adjusting the volume of the winding magazine 135. This allows operators to selectively adjust the number and volume of winding magazines 135 as needed to accommodate cables of different numbers and lengths, avoiding cable waste.

[0051] Furthermore, the adjustable reel 132 can be positioned on the winding shaft 120 so that the adjustable reel 132 can rotate synchronously with the winding shaft 120 around the rotation axis of the winding shaft 120.

[0052] In some embodiments, the guide channel 121 is provided with a plurality of connecting holes 1211, which are arranged at intervals along the axial direction of the winding shaft 120. The guide block 134 is bolted to the winding shaft 120 through the connecting holes 1211, so that the operator can adjust the relative position between the plurality of adjustable reels 132 and the winding shaft 120 by removing and installing the bolts, thereby improving the adjustment efficiency of the volume of the winding compartment 135.

[0053] Furthermore, after the guide block 134 is bolted to the connecting hole 1211 in the guide channel 121, the outer periphery of the winding shaft 120 and the side wall of the guide block 134 opposite to the winding shaft 120 are both located on a circle in a plane perpendicular to the axial direction of the winding shaft 120. This effectively prevents the cable from colliding and being damaged by the bolt during cable winding and unwinding, thereby improving the safety and reliability of the cable.

[0054] In other embodiments, there may be multiple guide channels 121, which are arranged at intervals along the circumference of the winding spool 120. Multiple guide blocks 134 are protruding from the inner peripheral wall of the adjustable reel 132, and the multiple guide blocks 134 are respectively housed in the multiple guide channels 121 to ensure the connection strength and stability between the adjustable reel 132 and the winding spool 120.

[0055] See Figures 1 to 9In this embodiment, the reel 130 may include a support ring plate 1331, a handle ring 1333, and a plurality of connecting rods 1332. The support ring plate 1331 extends circumferentially around the winding shaft 120. A guide block 134 protrudes from the inner peripheral wall of the support ring relative to the guide channel 121. The handle ring 1333 extends along the outer periphery of the support ring plate 1331 to facilitate the worker's hand contact and rotation of the handle ring 1333. The plurality of connecting rods 1332 are arranged at intervals along the circumference of the support ring, and the connecting rods 1332 extend radially along the support ring plate 1331. One end of the connecting rod 1332 is fixedly connected to the outer peripheral wall of the support ring, and the other end of the connecting rod 1332 is fixedly connected to the handle ring 1333 for fixing the support ring plate 1331 and the handle ring 1333, thereby making the rotation axis of the handle ring 1333 coaxial with the rotation axis of the support ring plate 1331.

[0056] Workers can rotate the handle ring 1333, which in turn drives the winding shaft 120 to rotate via the connecting rod 1332, the support ring plate 1331, and the guide block 134, thereby enabling manual winding and unwinding of the cable.

[0057] See Figures 1 to 4 , Figures 6 to 9 In this embodiment, the outer periphery of the reel 130 is formed by welding a circular tube. That is, the handle ring 1333 is formed by bending a circular tube, and the handle ring 1333 is welded to one end of the connecting rod 1332. This can reduce the weight of the reel 130, reduce the sharp edges of the reel 130, and reduce the probability of damaging the cable during the winding process.

[0058] See Figures 7 to 9 In this embodiment, the adjustable reel 132 includes a two-part reel structure. The two parts can be connected to each other to be combined and fitted onto the winding reel, so that the adjustable reel 132 can be detachably fitted onto the winding shaft 120, allowing the operator to adjust the number of adjustable reels 132 according to actual needs.

[0059] In some embodiments, the adjustable reel 132 divides the handle ring 1333, the connecting rod 1332, and the support ring plate 1331 into two symmetrical half-reel structures along the center line of a connecting rod 1332; wherein, the connecting rod 1332 is divided into a first connecting portion 13321 and a second connecting portion 13322. Engaging protrusions 13323 and engaging grooves 13324 are respectively provided on the opposing sidewalls of the first connecting portion 13321 and the second connecting portion 13322 to guide the assembly of the two half-reel structures, improve the assembly accuracy and efficiency of the two half-reel structures, and improve the utilization efficiency of the winding system 100.

[0060] In other embodiments, the first connecting portion 13321 and the second connecting portion 13322 are also provided with a locking structure (not shown in the figure) to connect and limit the two half-reel structures, preventing the two half-reel structures from loosening or falling off during rotation, and ensuring the stable and safe operation of the winding system 100. Furthermore, when needed, the operator can remove the adjustable reel 132 from the winding shaft 120 using the locking structure.

[0061] In other embodiments, the locking structure can be a bolted connection, a threaded connection, or a snap-fit ​​connection.

[0062] In some embodiments, the adjustable reel 132 can be divided into three or four parts so that the adjustable reel 132 can be quickly disassembled and assembled.

[0063] In this embodiment, the cable reel system 100 may further include a cable reel 110. The cable reel 110 may be disposed inside the cable reel compartment and is detachably connected to the housing. The cable reel 110 is used to carry the cable reel 120. The cable reel 120 is rotatable on the cable reel 110 for taking in and releasing the cable.

[0064] In some embodiments, the winding frame 110 is formed by bending sheet metal, which can reduce the overall weight of the winding system 100 while ensuring structural strength and load-bearing capacity, thereby reducing the production and transportation costs of the energy storage container.

[0065] In this embodiment, a detachable binding member (not shown in the figure) is provided on the reel 130. The binding member is used to secure the cable terminals to the reel 130, thereby preventing the cable terminals from colliding with the reel 130 or external parts during the transportation of the energy storage container, ensuring the safety and reliability of the cable.

[0066] In this embodiment, the cable reel system 100 may further include a hook (not shown in the figure). The hook is located within the reel compartment 135. The hook can hook and limit the cable, thereby enabling rapid cable reeling. Furthermore, when the cable reel system 100 releases the cable, the cable can automatically disengage, improving the ease of operation for workers.

[0067] In some embodiments, the hook is located on the side of the reel 135 near the reel 120, and the hook extends in the direction of rotation of the reel 120 during winding, so as to hook up and limit the cable.

[0068] See Figure 6In this embodiment, the winding system 100 may further include a drive structure 140 for driving the winding shaft 120 to rotate. The drive structure 140 is disposed on the winding frame 110 and is connected to the winding shaft 120 for transmission, thereby driving the winding shaft 120 to rotate, so that the cable can be wound into the winding hopper 135, or the cable can be unwound from the winding hopper 135 to the outside.

[0069] The drive structure 140 may include a motor 141 and a coupling 142. The motor 141 is located on one axial side of the winding shaft 120. One end of the coupling 142 is disposed at the end of the winding shaft 120 for transmission connection with the winding shaft 120, and the other end of the coupling 142 is detachably transmission connected to the motor 141 for switching between automatic and manual operating modes of the winding system 100.

[0070] When the coupling 142 moves toward the motor 141 and is connected to the motor 141, the cable reel system 100 is in automatic operation mode. At this time, the motor 141 can drive the coupling 142 to rotate forward or reverse, thereby driving the cable reel 120 to rotate forward or reverse, which can improve the cable winding and unwinding efficiency, improve the convenience of the cable reel system 100, and improve the utilization efficiency of the energy storage container.

[0071] When the coupling 142 is away from the motor 141 and the motor 141 is separated from the coupling 142, the cable reel system 100 is in manual operation mode. At this time, the operator can rotate the cable reel 120 by holding the handle ring 1333 or the connecting rod 1332 to manually reel in and unload the cable.

[0072] Furthermore, the winding system 100 integrates automatic and manual operation, allowing it to switch between automatic and manual modes. This enables the winding system 100 to adapt to various harsh operating scenarios and handle various malfunctions. For example, when the motor 141 or other components malfunction, the manual mode of the winding system 100 can prevent the winding system from failing to reel in or unwind the cable, thus improving its safety and stability.

[0073] In some embodiments, the motor 141 is embedded in the winding frame 110. The motor 141 is located on the axis of the winding spool 120, and the motor 141 and the winding spool 120 are spaced apart. A coupling 142 is disposed between the motor 141 and the winding spool 120. The coupling 142 is movable along the axial direction of the winding spool 120. One end of the coupling 142 is drive-connected to the winding spool 120, and the other end of the coupling 142 can move close to the motor 141 and be drive-connected to the motor 141, so that the winding system 100 is in an automatic operating mode, or the other end of the coupling 142 can move away from the motor 141 and be separated from the motor 141, so that the winding system 100 is in a manual operating mode.

[0074] In other embodiments, the motor 141 may be a hydraulic motor 141 having a forward rotation oil passage and a reverse rotation oil passage, so as to drive the winding shaft 120 to rotate forward and reverse respectively via the coupling 142.

[0075] In other embodiments, coupling 142 is connected to winding shaft 120, and coupling 142 and winding shaft 120 are coaxially arranged so that coupling 142 and winding shaft 120 can rotate synchronously.

[0076] Understandably, the number of structural components within the winding system 100 is relatively small, which effectively reduces the volume of the winding compartment required for the winding system 100. This improves the space utilization rate of the energy storage container, thereby reducing the production cost of the energy storage container.

[0077] See Figure 1 and Figure 2 In this embodiment, the cable winding system 100 may include two cable winding spools 120 and two drive structures 140 respectively drivingly connected to the two cable winding spools 120. The two cable winding spools 120 are spaced apart along their axial direction. The two drive structures 140 are respectively drivingly connected to the two cable winding spools 120 so that the two drive structures 140 can drive the two cable winding spools 120 to rotate, thereby enabling the two cable winding spools 120 to respectively perform cable winding and / or unwinding, or enabling the two cable winding spools 120 to simultaneously perform cable winding or unwinding, thereby improving the working efficiency of the cable winding system 100.

[0078] Furthermore, the two drive structures 140 are respectively located on opposite sides of the two winding spools 120, so as to facilitate the installation, adjustment, inspection and maintenance of the drive structures 140.

[0079] In some embodiments, the winding system 100 may further include a plurality of winding spools 120 and a plurality of drive structures 140 respectively drivingly connected to the plurality of winding spools 120. The plurality of winding spools 120 are coaxially arranged. The plurality of drive structures 140 can drive the plurality of winding spools 120 to take up and unwind wire respectively, thereby improving the utilization efficiency of the energy storage container.

[0080] See Figures 1 to 2 In this embodiment, the energy storage container may further include a hydraulic system 200. The hydraulic system 200 is housed within a hydraulic compartment and is connected to the drive structure 140, thereby enabling the winding shaft 120 to rotate via a motor 141. That is, the hydraulic system 200 is the power source for the winding system 100.

[0081] Meanwhile, by driving the drive structure 140 through the hydraulic system 200, the power source of the winding system 100 and the transmission wheel system between the winding system 100 can be effectively reduced, thereby reducing production and maintenance costs and ensuring the stable and reliable operation of the energy storage container.

[0082] The hydraulic system 200 may include an oil tank 210, a hydraulic pump, and a first directional valve 220. The oil tank 210 is disposed within a housing, and the hydraulic pump is used to pump out hydraulic oil. The first directional valve 220 has an input end and two output ends connected to the input end. The input end is connected to the hydraulic pump, and the two output ends are respectively connected to the drive structure 140 to drive the drive structure 140 to rotate the winding shaft 120 forward or reverse, thereby facilitating the winding and unwinding of the cable and improving the working efficiency of the winding system 100.

[0083] See Figures 1 to 2 In this embodiment, the oil tank 210 can be installed in the hydraulic compartment to separate the hydraulic system 200 from the energy storage system, thereby ensuring the safety of the energy storage system and the hydraulic system 200, and facilitating the mutual influence of the heat dissipated during the operation of the hydraulic system 200 and the energy storage system.

[0084] In some embodiments, the oil tank 210 may be made of an alloy material to enable rapid radiative heat dissipation and ensure the stable operation of the hydraulic system 200. In other embodiments, the oil tank 210 may be made of aluminum alloy.

[0085] In some embodiments, the housing has multiple heat dissipation holes on the side wall of the hydraulic chamber for heat dissipation of the hydraulic system 200. In other embodiments, the housing has multiple heat dissipation holes on the winding compartment for heat dissipation of the drive structure 140.

[0086] In some embodiments, a hydraulic pump may be installed inside the oil tank 210 to pump the hydraulic oil in the oil tank 210 out of the first directional valve 220, thereby reducing the volume of the hydraulic system 200 and improving the space utilization of the energy storage container.

[0087] See Figures 1 to 2 In this embodiment, the first directional valve 220 is disposed on the oil tank 210 and connected to the hydraulic pump, so as to facilitate the assembly, disassembly and maintenance of the hydraulic system 200, and to reduce the volume of the hydraulic system 200 and improve the space utilization of the energy storage container.

[0088] The first directional valve 220 can connect the hydraulic oil pumped out by the hydraulic pump to the forward and reverse oil circuits of the motor 141 through its two output terminals, respectively. This allows the motor 141 to drive the coupling 142 to rotate forward or reverse, thereby driving the winding shaft 120 to rotate forward or reverse, achieving automatic cable winding or unwinding, simplifying operation steps, and improving the working efficiency and convenience of the winding system 100.

[0089] In some embodiments, the first directional valve 220 may be a solenoid directional valve.

[0090] In some embodiments, an oil pipe is provided between the first reversing valve 220 and the motor 141, and is connected to the motor 141 via a directional joint 230. This allows the oil pipe to be located within or near the sheet metal structure of the winding frame 110, thereby protecting the oil pipe from scratches and damage. Furthermore, this reduces the space required for oil pipe installation and improves the space utilization of the energy storage container.

[0091] In some embodiments, the hydraulic system 200 may further include two first directional valves 220, the input ends of which are connected to a hydraulic pump to carry the hydraulic oil pumped out by the hydraulic pump. The two first directional valves 220 are respectively connected to two motors 141 to drive the two spools 120 to rotate, thereby driving the two spools 120 to rotate forward or backward respectively.

[0092] In some embodiments, the hydraulic system 200 may further include two first directional control valves 220 and a second directional control valve 240, with the two first directional control valves 220 respectively connected to two drive structures 140. The input end of the second directional control valve 240 is connected to a hydraulic pump, and the two output ends of the second directional control valve 240 are respectively connected to the input ends of the two first directional control valves 220, so that the operator can control the start and stop of the two drive structures 140 respectively by switching the second directional control valve 240.

[0093] When the operator switches the second reversing valve 240, the second reversing valve 240 can be connected to the two first reversing valves 220 respectively, so that the two first reversing valves 220 can be connected intermittently, and the two winding shafts 120 can rotate intermittently, so as to facilitate operator operation, reduce safety hazards, and improve the stability and reliability of the winding system 100.

[0094] In some embodiments, the second directional valve 240 may be a solenoid directional valve.

[0095] In this embodiment, the energy storage container may further include a control module (not shown in the figure). The control module is disposed on the container body and can be electrically connected to the hydraulic pump, the first reversing valve 220 and the second reversing valve 240, so as to control the start and stop of the hydraulic pump, the reversing of the first reversing valve 220 and the reversing of the second reversing valve 240 respectively.

[0096] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0097] See Figures 1 to 9 This application provides an energy storage container. When the energy storage container is in use, the operator can select the number and length of cables according to the needs of the actual application scenario. After determining the number and length of cables, the operator can disassemble and assemble the adjustable reel 132, thereby adjusting the number and volume of the reel compartments 135 formed between the multiple reels 130.

[0098] Once the number of reel 135 is determined, the operator can start the hydraulic pump and then adjust the second reversing valve 240 and the first reversing valve 220 to make the reel 120 rotate, thereby causing the cable to be wound and coiled inside the reel 135.

[0099] Once the cable winding is complete, the workers stop the hydraulic system 200 and are able to move the energy storage container to the power consumption site.

[0100] Once the energy storage container is moved to the power consumption site, the staff can start the hydraulic pump to rotate the cable reel 120, thereby allowing the cable in the reel 135 to be laid out to the outside. This facilitates the staff to connect the energy storage unit to the external power consumption site via the cable, effectively improving the utilization efficiency of the energy storage container.

[0101] Furthermore, in the event of a failure in the hydraulic system 200 or the drive structure 140, the operator can move the coupling 142 to separate it from the motor 141, thereby enabling the operator to manually reel in the wire and change its direction, ensuring the stable and reliable operation of the winding system 100 and making the energy storage container suitable for a variety of harsh application environments.

[0102] This application also provides a mobile energy storage vehicle. The mobile energy storage vehicle includes a vehicle body and an energy storage container as described above. The energy storage container is mounted on the vehicle body so that it can move with the vehicle body.

[0103] In some embodiments, when the energy storage container is mounted on the vehicle body, the opening of the winding compartment of the energy storage container may be located at the rear end and / or both sides of the vehicle body to facilitate the use of the winding system 100 in the winding compartment and improve the utilization efficiency of the mobile energy storage vehicle.

[0104] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
