Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, and in particular to an integrated photovoltaic, energy storage and charging cabinet. Background Technology

[0002] With the increasing popularity and continuous development of renewable energy technologies, integrated photovoltaic-storage-charging cabinets, as a type of integrated device that combines energy storage and charging functions, have been widely used in residential, commercial, and special scenarios (such as ships and offshore sites).

[0003] However, current integrated energy storage cabinets still face significant challenges in terms of ease of final deployment and relocation. Firstly, during equipment placement and movement, existing solutions primarily rely on forklift holes at the bottom of the cabinet or lifting rings at the top, requiring large machinery such as forklifts and cranes for handling and rough repositioning. In locations with limited space (such as home garages), complex ground conditions, or a lack of large machinery (such as ship decks or temporary construction sites), precise final positioning and manual fine-tuning are difficult, severely limiting application flexibility and user experience. Secondly, simply adding permanent casters to the cabinet for convenience, while improving mobility to some extent, fundamentally sacrifices the absolute stability and seismic resistance required for operation, posing safety hazards and failing to meet the safety standards for heavy electrical equipment. Therefore, existing technologies face a dilemma of balancing "easy movement" and "stable operation," resulting in cumbersome deployment and adjustment processes at user sites and a high dependence on specialized tools and external conditions.

[0004] Therefore, it is necessary to improve and optimize the existing integrated photovoltaic storage and charging cabinets, especially the support and movement structure of their integrated cabinets, in order to design an innovative mechanism that can be easily moved when needed and stably supported during operation. This would fundamentally solve the problems of equipment handling relying on large machinery and the difficulty in balancing mobility and operational stability, lower the user's operating threshold, and improve the equipment's deployment adaptability and ease of operation in different application scenarios. At the same time, it would also enable the cabinet door to be locked quickly and reliably. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated optical storage and charging cabinet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated photovoltaic storage and charging cabinet, comprising a cabinet body and a base disposed at the bottom of the cabinet body; a charging handle is mounted on the side of the cabinet body, and cabinet doors are hinged to the front and rear ends of the cabinet body, with a door lock assembly between the cabinet doors and the cabinet body; a liftable roller assembly is disposed on the base, and a hydraulic drive structure for driving the roller assembly to lift and lower, and a partition is disposed on the inner side wall of the cabinet body.

[0007] The door lock assembly includes a mounting base, a control handle, a first control lever, and a second control lever. The mounting base is fixed to the cabinet door. A linkage plate is horizontally rotatably connected to the mounting base. The control handle and the upper end of the linkage plate are rotatably connected. The lower end of the linkage plate is fixedly connected to an L-shaped locking rod, which can abut against the cabinet body. A gear is also fixed to the linkage plate. The first and second control levers are vertically slidably connected to the cabinet door. There are two of each type. A latch is fixed to the first control lever. A lock groove block that mates with the latch is fixed to the cabinet body. The first and second control levers are fixedly connected. The second control lever has a multi-toothed groove that mates with the gear. A lock is also fixed to the mounting base. A locking block that mates with the lock is fixed to the control handle.

[0008] The cabinet door is also fixed with guide block one and guide block two. The control rod one and guide block one are slidably connected, and the control rod two and guide block two are slidably connected.

[0009] The first control rod has multiple adjustment holes, which are interconnected and the width of the connection is smaller than the diameter of the adjustment hole. The second control rod has a circular hole, and fasteners are inserted into the circular hole and the adjustment hole.

[0010] The latch is also equipped with wheels.

[0011] The hydraulic drive structure includes an oil tank, a manual piston pump, a manual directional valve, and at least three single-acting hydraulic cylinders mounted on the cabinet or base. The inlet of the manual piston pump is connected to the oil tank, and its outlet is connected to the rodless chamber of each single-acting hydraulic cylinder through the manual directional valve. The cylinder body of each single-acting hydraulic cylinder is fixedly mounted on the base, and its piston rod is vertically downward and connected to the roller assembly.

[0012] The roller assembly includes a horizontal lifting plate and multiple rollers installed at the bottom of the lifting plate; the lower end of the piston rod of each single-acting hydraulic cylinder is fixedly connected to the lifting plate.

[0013] At least two vertical guide columns are provided between the lifting plate and the base; the lifting plate is provided with guide holes that slide with the guide columns.

[0014] The hydraulic drive structure also includes a hydraulic accumulator, which is connected to the pipeline between the outlet of the manual piston pump and the inlet of the manual directional valve.

[0015] The operating part of the manual plunger pump is a foot pedal; the foot pedal is located inside the operating port opened on the side of the base.

[0016] The lifting plate is provided with a clearance groove for avoiding the foot pedal during its lifting and lowering process.

[0017] The present invention has the following beneficial effects: By unlocking the operating handle to free it, and then closing the cabinet door, the operating handle drives the linkage plate to rotate, which in turn causes the L-shaped locking rod to abut against the cabinet body, causing the gear to mesh with the multi-tooth groove part, pushing the first and second control rods to move outward, and finally causing the lock tongue to embed into the lock groove block, realizing the multi-point locking function of the cabinet door, which is reliable and convenient.

[0018] By incorporating a roller assembly that can be lifted and lowered by a built-in hydraulic system, the heavy cabinet can be easily moved and precisely positioned manually without relying on external large lifting equipment. At the same time, by designing the rollers to be fully retractable, this design ensures that the equipment can be directly supported by a stable base during long-term operation. This fundamentally solves the contradiction between convenient movement and stable operation that is difficult to balance in traditional integrated energy storage cabinets, significantly reducing the operational threshold for users' on-site deployment and their reliance on professional tools.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 6 The present invention provides an integrated optical storage and charging cabinet: To reduce the reliance on heavy-duty energy storage cabinets for handling by large machinery and to resolve the trade-off between sacrificing operational stability due to the addition of permanent casters, this system achieves a balance between convenient manual movement and stable operation. It includes a cabinet body 2 and a base 1 fixedly mounted at the bottom of the cabinet body 2. The base 1 is equipped with a liftable caster assembly and a hydraulic drive structure for raising and lowering the caster assembly. When the cabinet needs to be moved, the caster assembly is driven down to lift the cabinet; when the cabinet is in place and ready for operation, the caster assembly is raised and directly and stably supported by the base 1. This structure allows the heavy energy storage cabinet to be freed from absolute dependence on forklifts or cranes. In confined spaces or areas where large machinery is inconvenient, the final position adjustment and movement can be completed manually by a single person. Simultaneously, in a fixed operating state, it achieves the same stability and safety as a cabinet without casters.

[0023] To lock the cabinet door 14, cabinet doors 14 are hinged to both the front and rear ends of the cabinet body 2. A door lock assembly 15 is provided between the cabinet door 14 and the cabinet body 2. The door lock assembly 15 includes a mounting base 1501, a control handle 1502, a first control rod 1505, and a second control rod 1504. The mounting base 1501 is fixed to the cabinet door 14. A linkage plate 1512 is horizontally rotatably connected to the mounting base 1501. The control handle 1502 and the connecting shaft at the upper end of the linkage plate 1512 are rotatably connected. Specifically, a protective cover plate 1509 is also rotatably mounted on the control handle. The lower end of the linkage plate 1512 is fixedly connected to an L-shaped locking rod 1503, and the L-shaped locking rod 1503 can abut against the cabinet body 2. Gear 1513 is also fixed on the disc 1512. Control rod 1505 and control rod 2 1504 are both vertically slidably connected to the cabinet door 14. There are two control rods 1505 and two control rods 2 1504. Lock tongue 1506 is fixed on control rod 1505. Lock groove block 201 that cooperates with lock tongue 1506 is fixed on the cabinet body 2. Control rod 1505 and control rod 2 1504 are fixedly connected. Control rod 2 1504 has a multi-tooth groove 1504a that cooperates with gear 1513. Lock 1510 is also fixed on the mounting base 1501. Locking block 1511 that cooperates with lock 1510 is fixed on the control handle 1502.

[0024] The cabinet door 14 is also fixed with guide block 1508 and guide block 2 1507. Control rod 1 1505 is slidably connected to guide block 1 1508, and control rod 2 1504 is slidably connected to guide block 2 1507.

[0025] The first control rod 1505 has multiple adjustment holes 1505a, which are interconnected and the width of the connection is smaller than the diameter of the adjustment hole 1505a. The second control rod 1504 has a round hole, and fasteners are inserted into the round hole and the adjustment hole 1505a.

[0026] The latch 1506 is also equipped with a wheel 1506a, which guides the latch 1506 to fit more smoothly into the lock groove block 201.

[0027] By unlocking the operating handle to free it, after closing the cabinet door 14, the operating handle 1502 drives the linkage plate 1512 to rotate, thereby causing the L-shaped locking rod 1503 to abut against the cabinet body 2, causing the gear 1513 to mesh with the multi-tooth groove part 1504a, pushing the first control rod 1505 and the second control rod 1504 to move outward, and finally causing the locking tongue 1506 to embed into the locking groove block 201, realizing the multi-point locking function of the cabinet door 14.

[0028] To achieve smooth, synchronous, and high-torque lifting of the roller assembly, the hydraulic drive structure of this system includes an oil tank 4 mounted on the cabinet 2 or base 1, a manual plunger pump 12, a manual directional valve 10, and four single-acting hydraulic cylinders 6. The cylinder body of each single-acting hydraulic cylinder 6 is fixedly mounted on the upper surface of the base 1, with its piston rod vertically downwards and connected to the roller assembly. The inlet of the manual plunger pump 12 is connected to the oil tank 4 via an oil pipe, and its outlet is connected in parallel to the rodless chamber of each single-acting hydraulic cylinder 6 via an oil pipe through the manual directional valve 10. Operating the manual directional valve 10 switches the oil circuit direction, controlling the flow of hydraulic oil. Through this structure, utilizing the principle of hydraulic transmission, the operator can convert a small foot force into a powerful hydraulic thrust by stepping on the manual plunger pump 12, which simultaneously and equally acts on the four single-acting hydraulic cylinders 6. This ensures absolutely synchronous lifting of the roller assembly, avoiding the asynchronous or jamming problems that may occur in mechanical linkage mechanisms, and providing sufficient driving force to support the weight of the entire cabinet.

[0029] To integrate multiple rollers into a rigid motion unit and ensure uniform force distribution and coordinated movement across multiple support points, the roller assembly specifically includes a horizontally positioned rectangular lifting plate 7 and four rollers 9 mounted at the four corners of the bottom surface of the lifting plate 7 via brackets. The lower ends of the piston rods of each single-acting hydraulic cylinder 6 are directly fixedly connected to the upper surface of the lifting plate 7 via flanges or threads. Through this structure, the four single-acting hydraulic cylinders 6 collectively drive a rigid lifting plate 7, making all rollers 9 a single moving component. This fundamentally eliminates the uneven force distribution or tilting that could result from independent action of multiple rollers, ensuring the stability and levelness of the cabinet during the lifting process.

[0030] To constrain the movement trajectory of the lifting plate 7, prevent horizontal deviation or rotation around the vertical axis during lifting, ensure smooth lifting, and protect the hydraulic cylinder from lateral forces, two vertical guide posts 8 are provided between the lifting plate 7 and the base 1. The lower end of the guide post 8 is fixed to the base 1, and the upper end passes through the guide hole opened on the lifting plate 7, forming a sliding fit with the lifting plate 7. Through the above structure, the guide post 8 provides precise vertical guidance for the lifting plate 7, ensuring that it can only move up and down along a set path, effectively avoiding the risk of jamming caused by load center of gravity deviation, and extending the service life of the hydraulic cylinder and the entire drive system.

[0031] To improve the smoothness of operation and pressure stability of the hydraulic system, and to achieve controllable slow descent during roller retraction, the hydraulic drive structure also includes a hydraulic accumulator 5. The hydraulic accumulator 5 is connected via a tee fitting to the main pipeline between the outlet of the manual piston pump 12 and the inlet of the manual directional valve 10. When the manual piston pump 12 is pressed, the hydraulic accumulator 5 absorbs oil pressure pulsations, making the lifting process smoother. When the manual directional valve 10 is in the neutral locked position, the hydraulic accumulator 5 compensates for minor system leaks, helping to maintain the roller position for a longer period. When switching to descent return oil, the hydraulic accumulator 5 provides back pressure, making the cabinet's descent speed under its own weight slow and controllable, avoiding the impact of a rapid fall. This structure significantly improves the safety and user experience of the entire operation.

[0032] To provide a labor-saving, convenient, and ergonomic operating method, and to integrate and hide the operating interface to avoid accidental touches and maintain a clean appearance, the operating part of the manual plunger pump 12 is designed as a foot pedal 11. The foot pedal 11 and the operating handle of the manual directional valve 10 are arranged adjacent to each other and located inside the operating port 101 opened on the side of the base 1. In the non-operating state, the operating port 101 can be covered by a cover plate. With the above structure, the user only needs to step on it to obtain power, making operation labor-saving and intuitive; all control elements are concentrated in a concealed interface, which not only facilitates operation but also protects the internal mechanism, keeping the appearance of the equipment as an industrial product.

[0033] To address the interference between the lifting plate 7 and the fixedly installed foot pedal 11 along the lifting path, and to ensure the completeness and smoothness of the lifting plate 7's movement, a rectangular clearance groove 701 is provided upwards on the rear edge of the lifting plate 7 corresponding to the installation position of the foot pedal 11. This structure provides the necessary passage space for the foot pedal 11 and its connecting rods, allowing the lifting plate 7 to pass unimpeded when lowered to its lowest position (roller 9 fully retracted) or raised to its highest position (roller 9 fully extended), thus ensuring the complete realization of the mechanism's function.

[0034] To optimize the internal space layout of the cabinet and achieve safe isolation and zoned management of electrical equipment and energy storage batteries, a partition 3 is horizontally fixed near the top of the inner wall of the cabinet 2. The partition 3 divides the interior of the cabinet 2 into an upper electrical cavity, a battery cavity, and a lower equipment cavity. Through this structure, the partition 3 can effectively prevent the heat generated by the electrical components from directly affecting the hydraulic structure such as the hydraulic energy storage device 5 below, improving the safety and reliability of the system operation, and also facilitating the organization and management of internal cables.

[0035] In practice, a charging handle is installed on the side of the cabinet, and the charging handle adopts the existing structure.

[0036] When the energy storage cabinet needs to be moved, the operator opens the operating port 101 on the side of the base 1 and switches the manual directional valve 10 to the "lift" position. Then, the operator continuously presses the foot pedal 11 to drive the manual plunger pump 12, pumping out the hydraulic oil from the oil tank 4. The pressurized oil simultaneously enters the rodless chambers of the four parallel single-acting hydraulic cylinders 6 through the manual directional valve 10, pushing the piston rods of each hydraulic cylinder to extend downwards synchronously. The piston rods push the lifting plate 7, which is fixed to it, downwards along the guide column 8, and the rollers 9 installed at the bottom of the lifting plate 7 descend to contact the ground. As the piston rods continue to extend, the rollers 9 lift the entire cabinet upwards until the bottom surface of the base 1 is completely off the ground. At this point, the weight of the entire cabinet is supported by the four rollers 9, and it can be easily moved manually to the target position.

[0037] When the energy storage cabinet is moved to the target location and needs to be fixed in place, the manual directional valve 10 is switched to the "lower" position. At this time, the oil circuits of the rodless chambers of the four single-acting hydraulic cylinders 6 are connected to the return oil circuit of the oil tank 4. Under the action of the cabinet's own weight, the oil in the hydraulic cylinders is forced back to the oil tank 4, and the piston rods retract upwards synchronously, driving the lifting plate 7 and the rollers 9 to rise. The cabinet then descends smoothly until the bottom surface of the base 1 is firmly grounded again, bearing the full weight, and the rollers 9 are fully raised off the ground or retracted to be flush with the bottom surface of the base. Finally, the manual directional valve 10 is reset to the "neutral" locked position, and the operating port 101 is closed, and the system is switched to a stable fixed working mode.

[0038] Throughout the process, the hydraulic accumulator 5 stabilizes the system pressure, ensures a smooth lifting process, and provides back pressure during descent to achieve a gentle drop. Through the combination of hydraulic drive and mechanical structure, this system can reliably and effortlessly switch between "easy movement" and "stable operation" modes for heavy-duty energy storage cabinets without any external power or large tools.
