Description

Technical Field

[0001] This invention relates to the field of energy storage equipment, and more particularly to a mobile and scalable photovoltaic device. Background Technology

[0002] Existing energy storage devices are mostly fixed structures, which mainly have the following problems: 1. Low power generation efficiency. Energy storage devices cannot be flexibly expanded. The photovoltaic modules of some devices are fixed in angle after installation and cannot be flexibly adjusted according to sunlight conditions and operating requirements, resulting in limited power generation area and low power generation efficiency. When energy storage devices are used in conjunction with diesel generators, the large amount of heat generated during the operation of the diesel generator will be directly radiated to the photovoltaic panels, causing the photovoltaic panels to heat up and significantly reducing their power generation performance. 2. Poor scalability. Energy storage devices cannot be flexibly moved or expanded, and cannot be used in various scenarios such as outdoor operations and emergency power supply. 3. Weak ability to cope with severe weather. Existing mobile energy storage devices lack effective mechanisms to cope with severe weather. When encountering strong winds, rain, or other weather conditions, the equipment is easily damaged. 4. Inconvenient maintenance. Dust and dirt easily accumulate on the surface of the photovoltaic panels, requiring manual cleaning and resulting in high maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide a mobile and expandable photovoltaic device to at least solve the technical problems of low power generation efficiency caused by the inability to flexibly expand and adjust the angle of existing energy storage devices in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A mobile and expandable photovoltaic device includes a support frame base. The support frame base integrates a photovoltaic module, a hydraulic device, a longitudinal push rod, a transverse push rod, a transverse push rod bracket, a push rod fixing bracket, a transverse push rod shaft, and a longitudinal push rod shaft. The hydraulic device is fixed to the support frame base via the push rod fixing bracket. The hydraulic device is hinged to the longitudinal push rod shaft and the transverse push rod shaft via the longitudinal push rod and the transverse push rod, respectively. The transverse push rod is fixed to the bottom of the photovoltaic module via the transverse push rod bracket. The longitudinal push rod shaft and the transverse push rod shaft are respectively positioned and installed with the photovoltaic module and the transverse push rod bracket, for driving the photovoltaic module to lift and steplessly adjust its angle.

[0005] Furthermore, the support frame base also integrates a heavy-duty slide rail, a photovoltaic panel, a photovoltaic bracket, a photovoltaic support shaft, a heavy-duty slide rail shaft, a photovoltaic fixing bracket, and a photovoltaic support base; the heavy-duty slide rail is slidably connected to the support frame base, driving the photovoltaic panel to slide smoothly along the support frame base; the photovoltaic module is fixed to the photovoltaic support shaft through the photovoltaic bracket, the photovoltaic fixing bracket, and the photovoltaic support shaft, the two ends of the photovoltaic support shaft are installed in the photovoltaic support base, and the photovoltaic support base is fixed to the bottom of the support frame base.

[0006] Furthermore, the support base also integrates a meteorological sensor and a control module. The control module is located at the bottom of one side of the support base and is electrically connected to the hydraulic device and the meteorological sensor, respectively, for controlling the coordinated contraction and extension of the bidirectional electric actuator of the hydraulic device.

[0007] Furthermore, a diesel generator is installed at the lower end of the support bracket base. When the diesel generator starts, the hydraulic device drives the longitudinal push rod and the transverse push rod to extend, lifting the photovoltaic panel and increasing the distance between the photovoltaic panel and the diesel generator, as well as the heat dissipation area of ​​the photovoltaic panel.

[0008] Furthermore, the heavy-duty slide rail is installed on the bottom side of the photovoltaic bracket, and the two ends of the heavy-duty slide rail shaft are fixed to the base of the support bracket, which plays a role in limiting and supporting the heavy-duty slide rail.

[0009] Furthermore, the hydraulic device is connected to the photovoltaic module via a transmission, and the lateral push rod is fixed to the side of the photovoltaic module.

[0010] Furthermore, the meteorological sensor is installed at the lower end of the support frame, and can collect environmental wind speed and precipitation signals in real time and transmit them to the control module.

[0011] Furthermore, the photovoltaic module is installed inside the photovoltaic support frame of the support bracket and is hinged to the support bracket frame. Furthermore, the photovoltaic panel is drivable and can be horizontally deployed along a heavy-duty slide rail, with stepless adjustment of the lifting angle of the photovoltaic panel.

[0012] Furthermore, dustproof devices are provided on both sides of the photovoltaic module. The dustproof devices are movable dustproof covers. When the photovoltaic module is retracted along the heavy-duty slide rail and the heavy-duty slide rail axis, the dustproof covers can be closed. After closing, they are attached to the surface of the photovoltaic module, which plays a role in protecting the photovoltaic module and photovoltaic panel from dust and impact.

[0013] The present invention produces the following technical effects: 1. High power generation efficiency. The photovoltaic modules can be flexibly expanded by the cooperation of heavy-duty slide rails and heavy-duty slide rail shafts, increasing the power generation area; the angle of the photovoltaic modules can be adjusted by hydraulic devices in conjunction with longitudinal push rods and transverse push rods to adapt to lighting conditions; when working in conjunction with a diesel generator, the photovoltaic modules can be automatically lifted to increase the distance between the photovoltaic panels and the diesel generator and the heat dissipation area of ​​the photovoltaic panels, avoiding heat interference and improving power generation efficiency.

[0014] 2. High scalability. Photovoltaic modules can be flexibly extended and retracted via heavy-duty sliding rails, and the supporting bracket base can be moved flexibly, making it suitable for various scenarios such as outdoor operation and emergency power supply.

[0015] 3. Strong resistance to severe weather. Through the coordinated action of meteorological sensors and control modules, the photovoltaic modules can automatically retract in strong winds to avoid equipment damage; in moderate rain, the photovoltaic panels can automatically rise and be cleaned by rainwater, adapting to severe weather.

[0016] 4. Easy maintenance. The dustproof device effectively protects the photovoltaic modules, reduces dust accumulation, and combined with the automatic rainwater cleaning function, reduces manual maintenance costs. Attached Figure Description

[0019] To better understand the purpose, structure, and function of this invention, a mobile and expandable photovoltaic device of this invention will be described in further detail below with reference to the accompanying drawings. It should be emphasized that the structural forms described in the following embodiments are merely illustrative, and the mobile and expandable photovoltaic device of this invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0020] like Figure 1 , Figure 2As shown, a mobile and expandable photovoltaic device includes a support frame base 1. The support frame base 1 integrates a photovoltaic module 2, a hydraulic device 4, a longitudinal push rod 11, a transverse push rod 12, a transverse push rod bracket 13, a push rod fixing bracket 14, a transverse push rod shaft 15, and a longitudinal push rod shaft 18. The hydraulic device 4 is bolted to the support frame base 1 via the push rod fixing bracket 14. The push rod fixing bracket 14 fits tightly against the support frame base 1, and the bolt connection is secure, preventing the hydraulic device 4 from shifting during operation. Preferably, the hydraulic device 4 is driven by a small hydraulic pump, resulting in a fast response speed. The output end of the hydraulic device 4 is hinged to the longitudinal push rod shaft 18 and the transverse push rod shaft 15 via the longitudinal push rod 11 and the transverse push rod 12, respectively. The transverse push rod 12 is fixed to the bottom of the photovoltaic module 2 via the transverse push rod bracket 13. The longitudinal push rod shaft 18 and the transverse push rod shaft 15 are respectively limited and installed in the corresponding shaft holes of the photovoltaic module 2 and the transverse push rod bracket 13 to ensure the stability of the push rod extension and retraction, thereby driving the photovoltaic module 2 to lift and steplessly adjust the angle.

[0021] like Figure 1 , Figure 2 As shown, the supporting bracket base 1 also integrates a photovoltaic module 2, a heavy-duty slide rail 3, a photovoltaic panel 8, a photovoltaic bracket 9, a photovoltaic support shaft 10, a heavy-duty slide rail shaft 16, a photovoltaic fixing bracket 17, and a photovoltaic support base 19. The photovoltaic panel 8 can be easily slid out through the sliding engagement of the heavy-duty slide rail 3 and the heavy-duty slide rail shaft 16. The heavy-duty slide rail 3 is slidably connected to the supporting bracket base 1, and the heavy-duty slide rail shaft 16 passes through both ends of the heavy-duty slide rail 3, supporting the heavy-duty slide rail 3 and reducing its sliding friction, thus driving the photovoltaic panel 8 to slide smoothly along the supporting bracket base 1. The photovoltaic module 2 is fixed to the photovoltaic support shaft 10 via the photovoltaic bracket 9, the photovoltaic fixing bracket 17, and the photovoltaic support shaft 10. Both ends of the photovoltaic support shaft 10 are installed inside the photovoltaic support base 19, and the photovoltaic support base 19 is fixed to the bottom of the supporting bracket base 1.

[0022] like Figure 1 As shown, the support frame base 1 also integrates a meteorological sensor 5 and a control module 7. The control module 7 is electrically connected to the hydraulic device 4 and the meteorological sensor 5, respectively, and is used to control the coordinated operation of the various components. The control module 7 is located at the bottom of one side of the support frame base 1 and is electrically connected to the hydraulic device 4 and the meteorological sensor 5, respectively, and is used to control the coordinated contraction and extension of the bidirectional electric actuator of the hydraulic device 4.

[0023] like Figure 3 As shown, the diesel generator 20 is installed at the preset mounting position at the lower end of the support bracket 1. It works in conjunction with the photovoltaic module 2 to provide backup power when photovoltaic power is insufficient, ensuring continuous and stable power supply to the energy storage device and improving the synergy and practicality of the energy storage device.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, when the diesel generator 20 starts, after the control module 7 receives the signal, the hydraulic device 4 drives the longitudinal push rod 11 and the transverse push rod 12 to extend, lifting the photovoltaic panel 8, increasing the distance between the photovoltaic panel 8 and the diesel generator 20, and increasing the heat dissipation area of ​​the photovoltaic panel 8, thus preventing the heat generated by the diesel generator 20 from affecting the power generation performance of the photovoltaic panel 8. At the same time, the transverse push rod 12 can drive the photovoltaic panel 8 to unfold horizontally along the heavy-duty slide rail 3, realizing free unfolding and retraction on the plane.

[0025] like Figure 1 As shown, the support bracket base 1 is made of high-strength steel welded together, which has good load-bearing capacity and mobility. The bottom can be equipped with casters to facilitate equipment transfer, while also providing storage space for the photovoltaic module 2.

[0026] like Figure 1 As shown, the heavy-duty slide rail 3 is installed between the photovoltaic bracket 9 and the photovoltaic module 2. The heavy-duty slide rail 3 is slidably connected to the support bracket base 1 via a heavy-duty slide rail shaft 16. The heavy-duty slide rail shaft 16 passes through both ends of the heavy-duty slide rail 3 and cooperates with the bearing seat of the support bracket base 1. The bearing seat is fixed to the preset position of the support bracket base 1 by welding, which limits and supports the heavy-duty slide rail 3 and prevents it from shifting during sliding. Preferably, the heavy-duty slide rail 3 is made of 2mm thick galvanized sheet, with a surface coated with anti-corrosion paint, achieving a corrosion resistance level of C5. It can stably bear the overall weight of the photovoltaic module 2, with low sliding resistance, allowing the photovoltaic module 2 to slide out and retract quickly, ensuring the convenience of expanding and storing the photovoltaic module 2. The heavy-duty slide rail 3 can also be equipped with a locking mechanism to ensure the stability of the photovoltaic module 2 after expansion.

[0027] like Figure 1 , Figure 2 As shown, the photovoltaic module 2 is fixed to the photovoltaic support shaft 10 via a photovoltaic bracket 9, a photovoltaic fixing bracket 17, and a photovoltaic support shaft 10. Both ends of the photovoltaic support shaft 10 are embedded in photovoltaic support seats 19, which are welded to the bottom of the support frame base 1 to prevent the photovoltaic module 2 from loosening during movement and adjustment. The photovoltaic module 2 is embedded within a pre-set cavity in the support frame base 1 for easy storage and protection. The photovoltaic panel 8 is laid on the surface of the photovoltaic module 2 and firmly fixed to it, ensuring efficient light absorption.

[0028] like Figure 1As shown, preferably, the control module 7 is a PLC controller, which is embedded in the mounting cavity on the side of the support bracket base 1; the control module 7 is electrically connected to the hydraulic device 4 and the meteorological sensor 5 respectively, and the connection is made with waterproof wires to ensure safety for outdoor use; the control module 7 has a preset control program, which can realize two modes: manual control and automatic control, which can be switched by the operator according to the actual working conditions. It is used to control the bidirectional electric push rod of the hydraulic device 4 to retract and extend in coordination, so as to realize the angle adjustment, extension and retraction of the photovoltaic module 2 and the photovoltaic panel 8.

[0029] like Figure 1 , Figure 2 As shown, the meteorological sensor 5 is installed at the bottom of the support base 1 and can collect meteorological signals such as ambient wind speed and precipitation in real time, and transmit the signals to the control module 7. When the wind speed detected by the meteorological sensor 5 reaches the preset strong wind threshold, preferably when the wind speed reaches level 8 or above, such as 17.2-20.7 m / s, the control module 7 works in conjunction with the meteorological sensor 5 to trigger the photovoltaic module 2 retraction command within a few seconds, control the hydraulic device 4 to drive the longitudinal push rod 11 and the transverse push rod 12 to retract, and at the same time control the heavy-duty slide rail 3 to slide along the heavy-duty slide rail shaft 16 to quickly retract the photovoltaic panel 8 into the support base 1. The photovoltaic support shaft 10 and the photovoltaic support seat 19 play a stabilizing support role. After retraction, the photovoltaic module 2 fits into the support base 1, realizing wind protection for the equipment. When the precipitation detected by the meteorological sensor 5 reaches the level of moderate rain, the control module 7 automatically controls the hydraulic device 4 to drive the longitudinal push rod 11 and the transverse push rod 12 to extend. With the adjustment of the longitudinal push rod shaft 18 and the transverse push rod shaft 15, the photovoltaic module 2 is raised to a preset angle. Preferably, the preset angle is 45°-60°. The photovoltaic bracket 9 and the photovoltaic fixing bracket 17 ensure the stability of the photovoltaic module 2 after it is raised. After being raised, the photovoltaic panel 8 is tilted. The gravity flushing effect of the rainwater automatically cleans the dust and stains on the surface of the photovoltaic module 2, ensuring the light transmittance of the photovoltaic panel 8. No manual cleaning is required, reducing maintenance costs.

[0030] like Figure 1 As shown, the dustproof device 6 is a movable dustproof cover, corresponding to the left and right sides of the photovoltaic module 2, and is hinged to the support bracket base 1. The hinge uses a wear-resistant pivot, which facilitates the flexible opening and closing of the dustproof device 6 cover. The dustproof device 6 is made of waterproof and dustproof material and is attached to the surface of the photovoltaic module 2. When the photovoltaic module 2 is retracted along the heavy-duty slide rail 3 and the heavy-duty slide rail shaft 16, the dustproof cover can automatically close, providing protection against dust and debris impacts to the photovoltaic module 2 and photovoltaic panel 8, preventing dust and debris from entering the interior of the photovoltaic module 2 and affecting the normal operation of the energy storage equipment.

[0031] The working principle of this invention is as follows: This invention utilizes the sliding engagement of the heavy-duty slide rail 3 and the heavy-duty slide rail shaft 16 to slide the photovoltaic module 2 out from the support base 1, increasing the energy storage area and improving the total energy storage capacity. Through the hydraulic drive of the hydraulic device 4, the longitudinal push rod 11 and the transverse push rod 12 are extended and retracted, causing the photovoltaic module 2 to rise around the photovoltaic support shaft 10, adjusting the angle between the photovoltaic panel 8 and the sunlight to maximize solar energy utilization. Simultaneously, when the diesel generator is operating, raising the photovoltaic panel 8 increases the heat dissipation distance and area, reducing the temperature of the photovoltaic panel 8 and preventing a decrease in power generation efficiency due to excessive temperature. The weather sensor 5 detects the ambient wind speed and transmits the electrical signal to the control module 7. The control module 7 triggers the retraction of the heavy-duty slide rail 3 according to a preset threshold, achieving strong wind protection. The control module 7 receives the precipitation signal transmitted by the weather sensor 5. When moderate rain is reached, the hydraulic device 4 is controlled to raise the photovoltaic panel 8 to a large tilt angle, utilizing the gravity of the rainwater to remove floating dust and dirt from the surface of the photovoltaic panel 8, achieving automatic cleaning. By embedding and installing dustproof devices 6 within the photovoltaic module 2, the corrosion of photovoltaic module 2 by floating dust and impurities is reduced, thus extending the service life of the energy storage equipment.

[0032] In use, the photovoltaic module 2 can be expanded via the heavy-duty slide rail 3, allowing for flexible increases in energy storage area as needed; the photovoltaic panel 8 is automatically lifted via the hydraulic device 4, increasing the heat dissipation distance and area, reducing the heat impact of the diesel engine 20 under cooperative operating conditions, and also reducing the impact of excessively high ambient temperatures; the photovoltaic module 2 automatically retracts for protection through the collaboration of the meteorological sensor 5 and the control module 7; the photovoltaic panel 8 is automatically lifted during moderate rain to achieve automatic rainwater cleaning, reducing maintenance costs; and the integrated design allows for the installation of casters at the bottom of the support bracket base 1, facilitating flexible movement of the equipment.

[0033] This invention enables the photovoltaic module 2 to be expandable and angle adjustable, significantly improving power generation efficiency; it is compatible with diesel generator working conditions, solving the problem of heat affecting power generation; it has functions such as strong wind protection, automatic rainwater cleaning, and dust prevention, and has strong resistance to severe weather and low maintenance costs; the equipment is flexible and suitable for various outdoor scenarios.
