Description

Technical Field

[0001] This invention belongs to the field of photovoltaic energy storage technology, and particularly relates to mobile photovoltaic energy storage devices. Background Technology

[0002] Mobile photovoltaic energy storage devices have been widely used in emergency power supply, outdoor operations and electric vehicle charging due to their clean and flexible characteristics.

[0003] In the prior art, patent CN212992027U discloses a mobile photovoltaic energy storage power generation charging device. This device achieves the functions of moving and fixing by setting a triangular support frame and solar panels on the top of the box and configuring rollers and support pads controlled by electric push rods at the bottom.

[0004] However, the solar panels of this device are always exposed to the elements, making them highly susceptible to damage from collisions and other human-caused damage during transportation, which affects their lifespan and power generation efficiency. Summary of the Invention

[0005] To address the problems in the prior art, the present invention proposes the following technical solution: This invention provides a mobile photovoltaic energy storage device, comprising: Energy storage components; Photovoltaic modules, wherein the photovoltaic modules are disposed on top of the energy storage modules; A mobile component includes wheel seats evenly distributed at the bottom of an energy storage component, a wheel body rotatably mounted on the wheel seat, and a locking block rotatably mounted on the wheel seat, with a locking part provided on the locking block near the wheel body; The protective assembly includes a protective cover that is movably disposed along a longitudinal direction; An auxiliary plate extending longitudinally is fixedly installed on the outer wall of the protective cover. An upper fixed arm and a lower fixed arm are spaced apart at the bottom end of the auxiliary plate and near the end where the movable component is installed. In the first state, the auxiliary plate is moved upward until the protective cover is placed on the outside of the photovoltaic module. During this process, the auxiliary plate drives the lower fixed arm to move upward and abut against the locking block, causing it to rotate and finally moving the locking part away from the wheel body. This state facilitates the movement of the device. In the second state, the auxiliary plate is moved downwards, and the protective cover gradually moves away from the photovoltaic module to expose the photovoltaic module. During this process, the auxiliary plate drives the upper fixed arm to move downwards to abut against the locking block, causing it to rotate and finally making the locking part tightly abut against the wheel body. In this state, the device is locked.

[0006] As a preferred embodiment of the above technical solution, the top of the protective cover may also be detachably provided with a protective cap.

[0007] As a preferred embodiment of the above technical solution, the protective cover is provided with plug-in ears on both the front and rear sides, and the bottom of the protective cover is provided with a plug-in pin corresponding to the plug-in ears, and the plug-in pin is plugged into the plug-in ears.

[0008] As a preferred embodiment of the above technical solution, the energy storage component includes a housing, a sealed door hinged to the front of the housing, and a battery pack and a socket disposed in the inner chamber of the housing, wherein the battery pack and the socket are electrically connected.

[0009] As a preferred embodiment of the above technical solution, the photovoltaic module is disposed on top of the energy storage module. The photovoltaic module includes a base, and a rotating frame is symmetrically and rotatably disposed on the base. A photovoltaic panel is disposed on the rotating frame, and the photovoltaic panel is electrically connected to the battery pack.

[0010] As a preferred embodiment of the above technical solution, a driving component is further provided on the base, the output end of the driving component is hinged to the tilting frame, and the other end of the driving component is hinged to the base.

[0011] As a preferred embodiment of the above technical solution, mounting brackets are provided on both side walls of the energy storage component housing. The mounting brackets are rotatably equipped with threaded rods, and threaded sleeve blocks are fixedly provided on the auxiliary plate on the side where they are located. The threaded sleeve blocks are fitted onto the threaded rods and are threadedly engaged with them.

[0012] As a preferred embodiment of the above technical solution, a second driving component is also provided on both sides of the energy storage component housing, and the output end of the second driving component is fixedly connected to the threaded rod.

[0013] The beneficial effects of this invention are as follows: This invention, through the design of a moving component and a protective component, allows for several modes of operation. In the first state (moving state), the protective cover rises and completely covers the outside of the photovoltaic module, providing physical protection against collisions or dust contamination during transportation. Simultaneously, the lower fixed arm on the auxiliary plate drives the locking block to rotate, automatically disengaging the locking part from the wheel body and enabling rapid unlocking of the walking mechanism, facilitating the overall movement of the device. In the second state (working state), the protective cover descends, exposing the photovoltaic module for normal power generation. At the same time, the upper fixed arm on the auxiliary plate presses down on the locking block, causing the locking part to press tightly against the wheel body, achieving automatic parking and locking, ensuring the device is stable and reliable during operation and does not shift.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0016] Example like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The diagram shown is a front view of the energy storage device in the embodiment (in a stopped state). Figure 2 The diagram shown is a front view of the photovoltaic module in the embodiment; Figure 3 What is shown is Figure 1 Top view diagram; This device includes: Energy storage component 10 includes a housing with a hinged sealing door 11 on the front side of the housing. The inner chamber of the housing contains a battery pack and a socket, which are electrically connected.

[0017] A photovoltaic module 20 is disposed on top of an energy storage module 10. The photovoltaic module 20 includes a base 21, on which a rotating frame 22 is symmetrically and rotatably disposed. A photovoltaic panel 23 is disposed on the rotating frame 22, and the photovoltaic panel 23 is electrically connected to the battery pack.

[0018] The enclosure serves as the main structure, providing mechanical support and protection for internal components. The sealed door 11 ensures internal dust and water resistance and facilitates maintenance and repair. The enclosure is equipped with a battery pack for storing the electrical energy generated by the photovoltaic modules 20. The socket is electrically connected to the battery pack to provide power output to the outside.

[0019] Specifically, a drive unit 24 is also provided on the base 21. The output end of the drive unit 24 is hinged to the flipping frame 22, and the other end is hinged to the base 21.

[0020] The drive component 24 is an existing electric push rod, hydraulic cylinder, etc., with both ends hinged to the flipping frame 22 and the base 21 respectively. It is used to adjust the tilt angle of the photovoltaic panel 23. The adjustable tilt angle design can adjust the tilt angle of the photovoltaic panel 23 according to the local latitude and season to improve the power generation efficiency. There are two sets of flipping frame 22, photovoltaic panel 23 and drive component 24 symmetrically arranged.

[0021] The base 21 is fixedly installed on the top of the box. Two rotating shaft brackets are provided in the middle of the base 21. The rotating shaft brackets are provided with rotating shafts. The two flipping frames 22 are respectively rotated with the base 21 through the rotating shafts at their corresponding positions.

[0022] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, Figure 1 The diagram shown is a front view of the energy storage device in the embodiment (in a stopped state). Figure 4 What is shown is Figure 1 Enlarged schematic diagram of the structure at point A in the middle; Figure 5 The diagram shown is a front view of the energy storage device in the embodiment (in a moving state); Figure 6 What is shown is Figure 5 Enlarged schematic diagram of the structure at point B; Also includes: The mobile component includes wheel seats 31 evenly distributed at the bottom of the energy storage component 10, a wheel body 32 rotatably disposed on the wheel seat 31, a locking block 33 rotatably disposed on the wheel seat 31, and a locking part 34 disposed on the locking block 33 near the wheel body 32. The protective assembly includes a protective cover 42 that is movably disposed along the longitudinal direction; An auxiliary plate 41 extending longitudinally is fixedly installed on the outer side wall of the protective cover 42. An upper fixed arm 52 and a lower fixed arm 53 are spaced apart at the bottom end of the auxiliary plate 41 and near the end where the moving component is installed. In the first state (e.g.) Figure 5 As shown), the auxiliary plate 41 is moved upward until the protective cover 42 is placed on the outside of the photovoltaic module 20. During this process, the auxiliary plate 41 drives the lower fixed arm 53 to move upward and abut against the locking block 33, causing it to rotate and finally making the locking part 34 move away from the wheel 32. This state facilitates the movement of the device. In the second state (such as) Figure 1As shown), the auxiliary plate 41 moves downward, and the protective cover 42 gradually moves away from the photovoltaic module 20, exposing the photovoltaic module 20. During this process, the auxiliary plate 41 drives the upper fixed arm 52 to move downward and abut against the locking block 33, causing it to rotate and finally making the locking part 34 tightly abut against the wheel body 32. In this state, the device is locked.

[0023] Figure 5 The state shown is the first state, i.e., the moving state; Figure 1 The state shown is the second state, i.e., the locked state.

[0024] Wheel bases 31 and wheel bodies 32 are evenly distributed at the four corners of the bottom of the box to provide support and enable movement; locking blocks 33 swing around their pivot, allowing locking parts 34 to switch between pressing against the wheel surface and disengaging from the wheel surface.

[0025] The protective cover 42 can cover the photovoltaic module 20 to prevent impact, and the auxiliary plate 41 extends longitudinally to serve as a transmission medium.

[0026] When the auxiliary plate 41 rises, the protective cover 42 rises to protect the photovoltaic module 20. At the same time, the lower fixed arm 53 on the auxiliary plate 41 pushes the locking block 33 upward to rotate, the locking part 34 moves away from the wheel 32, and the wheel 32 is unlocked. At this time, the device can be moved as needed.

[0027] When the auxiliary plate 41 descends, the protective cover 42 descends, releasing the protective function on the photovoltaic module 20. At the same time, the upper fixed arm 52 presses down the locking block 33, causing the locking part 34 to press against the wheel body 32, locking the wheel body 32 so that it cannot move. At this time, the fixing device is in working state.

[0028] like Figure 3 , Figure 5 , Figure 7 As shown, Figure 3 What is shown is Figure 1 Top view diagram in the diagram, Figure 5 The diagram shown is a front view of the energy storage device in the embodiment (in the state of movement). Figure 7 What is shown is Figure 5 Top view diagram; The protective cover 42 has a horizontally placed U-shaped structure.

[0029] When the protective cover 42 is placed on the outside of the photovoltaic module 20, it forms a three-sided enclosure (front, back, and side), effectively preventing collisions.

[0030] The top of the protective cover 42 can also be detachably fitted with a protective cover 43.

[0031] The protective cover 43 can further close the top opening of the protective cover 42, thereby increasing the overall protective space.

[0032] The protective cover 42 has plug ears 421 on both the front and rear sides, and the bottom of the protective cover 43 has a plug pin 431 corresponding to the plug ears 421. The plug pin 431 is plugged into the plug ears 421.

[0033] The plug pin 431 and the plug ear 421 correspond one-to-one, and the protective cover 42 and the protective cover 43 can be quickly installed and removed through plug-in and pull-out cooperation.

[0034] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the energy storage device in the embodiment (in a stopped state). Mounting brackets 61 are provided on both sides of the energy storage component 10 housing. Threaded rods 62 are rotatably mounted on the mounting brackets 61. Threaded sleeve blocks 63 are fixedly mounted on the auxiliary plate 41 on the side where the mounting brackets 61 are located. The threaded sleeve blocks 63 are fitted onto the threaded rods 62 and are threadedly engaged with them. The energy storage component 10 is also equipped with a second drive component 64 on both sides of the housing. The output end of the second drive component 64 is fixedly connected to the threaded rod 62, which drives the threaded rod 62 to rotate.

[0035] The second driving component 64 is a geared motor that provides power. When the second driving component 64 is started, it drives the threaded rod 62 to rotate, and the threaded sleeve block 63 moves along the axial (longitudinal) direction of the threaded rod 62, thereby driving the auxiliary plate 41 and the protective cover 42 to rise and fall synchronously.

[0036] The threaded sleeve 63 slides with the side wall of the housing, thereby preventing the threaded sleeve 63 from rotating.

[0037] Working principle: When using this device, the state can be switched according to the usage requirements. In the first state (i.e., the moving state), the second driving component 64 is activated. The second driving component 64 drives the threaded rod 62 to rotate, and through the threaded sleeve block 63, the auxiliary plate 41 moves upward, so that the protective cover 42 covers the outside of the photovoltaic module 20. During this process, the auxiliary plate 41 drives the lower fixed arm 53 to move upward and abut against the locking block 33, causing it to rotate and finally moving the locking part 34 away from the wheel body 32, thereby facilitating the movement of the device. In the second state (i.e., the locked state), the second drive component 64 is activated. The second drive component 64 drives the threaded rod 62 to rotate in the opposite direction. Through the threaded sleeve block 63, the auxiliary plate 41 moves downward. The protective cover 42 gradually moves away from the photovoltaic module 20, exposing the photovoltaic module 20. During this process, the auxiliary plate 41 drives the upper fixed arm 52 to move downward and abut against the locking block 33, causing it to rotate and finally making the locking part 34 tightly abut against the wheel body 32. In this state, the device is locked.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
