When solar energy needs to be collected, the whole device can be moved to a designated location outdoors and the motor is started. When the motor is started, it will drive the driving wheel to rotate, and then the threaded tube fixedly connected to the driven wheel will start to rotate on the outer surface of the positioning rod. As the threaded tube rotates, under the action of screw connection, the second hinge seat starts to move upward along the threaded tube, that is, the support rod is pushed by the connecting rod hinged to the second hinge seat to rotate outward along the first hinge seat, and finally the support rod is spread out horizontally, so that the photovoltaic panel in the mounting plate on the support rod starts to face the sun for photovoltaic power generation, and the generated electricity is stored in the storage battery.

[0014] The present invention provides a solar charging device that is convenient for adjusting the angle of the photovoltaic panel. It has the following beneficial effects: 1. This solar charging device, which is easy to adjust the angle of the photovoltaic panel, can install the mounting plate in an openable and closable manner so that the mounting plate can be folded when needed for transportation, greatly reducing the space occupied during transportation and improving transportation efficiency. At the same time, when encountering rain, snow and strong winds, the mounting plate can also be closed to greatly reduce the wind resistance directly suffered by the device, thereby improving the installation stability of the device. The battery can also be installed on the second hinged seat so that the battery itself is in the air, and the working battery can be cooled by natural wind, thereby greatly improving the working stability of the battery, which is different from the safety hazard caused by the sealed installation of the battery in the current solar charging device.

[0015] 2. The solar charging device, which is easy to adjust the angle of the photovoltaic panel, has a top cover fixedly connected to the inner upper surface of the mounting plate, and a shielding film fixedly connected to the lower surface of the mounting plate. That is, when the mounting plate is unfolded for operation, the top cover and the shielding film cooperate to keep the space below the mounting plate in a shielded state, thereby avoiding the problem of rapid temperature rise and shortening the service life of the battery due to direct sunlight. When the mounting plate is folded, the top cover and the shielding film cooperate with each other to keep the threaded rod in a relatively sealed state, thereby isolating the parts and batteries of the device from rainwater when the mounting plate is folded up on rainy days, greatly improving the overall service life of the device. The bottom of the top cover is set to a corrugated shape, so that the deformation force of the bottom of the top cover can be greatly improved, thereby greatly extending the service life of the top cover when it is in a deformed state for a long time.

[0016] 3. The solar charging device is convenient for adjusting the angle of the photovoltaic panel. When the mounting plate is folded, the second hinge seat is moved downward, and the top plate is pulled downward by the pull rod, and the extrusion bag is squeezed, so that the extrusion bag transmits its internal air pressure to the expansion groove in the shielding film, so that when the mounting plate is folded, the shielding film between the adjacent mounting plates expands to buffer the mounting plate, thereby avoiding the problem that the mounting plates collide with each other during the folding process and cause damage to the photovoltaic panel. When the second hinge seat moves downward, the inner end of the connecting rod is also moved downward, and the pull rope is driven downward. When the pull rope moves downward, a pulling force is generated on the matching rod, and the moving column is pulled by the ring to start sliding in the No. 1 slide groove, and then the surface of the photovoltaic panel is cleaned through the outer surface of the cleaning tube. At the same time, the angle of the photovoltaic panel is changed synchronously, so that the dust cleaned by the cleaning tube starts to slide along the gradually inclined photovoltaic panel, and finally leaves the photovoltaic panel through the cleaning groove, thereby realizing automatic cleaning of the photovoltaic panel when the mounting plate is folded in rainy and snowy weather, ensuring that the photovoltaic panel is always in a stable working state.

[0017] 4. For this solar charging device that facilitates the adjustment of the angle of the photovoltaic panel, when it moves in cooperation with the rod, it will squeeze the elastic telescopic rod, so that the elastic telescopic rod conveys the internal air pressure to the elastic telescopic plate, and then the elastic telescopic plate begins to expand, squeezing both sides of the elastic plate at the bottom, making the elastic plate at the bottom gradually tend to be horizontal and expand downward, thus greatly increasing the contact area between the cleaning pipe and the photovoltaic panel, and then greatly improving the cleaning efficiency of the photovoltaic panel. When the elastic telescopic rod is squeezed to the limit, it starts to slide on the bottom surface of the mounting plate, and then starts to drive the expanded cleaning pipe to clean the photovoltaic panel, so as to realize that after the photovoltaic panel expands, the cleaning pipe disengages from the contact with the photovoltaic panel through the retracted elastic plate, avoiding the problem that the cleaning pipe contacts the photovoltaic panel for a long time when not working and causing damage to the photovoltaic panel.

[0027] Second Embodiment: As Figures 1 to 8 shown, the cleaning mechanism 4 includes a first chute 41 symmetrically penetrating and formed on the inner surfaces of both sides of the mounting plate 310. A cleaning groove 42 is penetratingly formed on the inner surface of the outer end of the mounting plate 310. The first chute 41 and the cleaning groove 42 are arranged perpendicular to each other. A moving column 43 is slidably connected inside the first chute 41. An auxiliary groove 44 is formed in the middle of the moving column 43. The auxiliary groove 44 is tubular, and a cleaning tube 45 is fixedly connected to the inner surface of the auxiliary groove 44. The cleaning tube 45 is made of soft cloth material.

[0028] Sleeve rings 46 are fixedly sleeved on the outer surfaces of both sides of the moving column 43. A mating rod 47 is fixedly connected to the bottom surface of the sleeve ring 46. The mating rod 47 is L-shaped. Second chutes 48 are penetratingly formed on both sides of the mounting plate 310. The mating rod 47 is slidably connected to the inner surface of the second chute 48. One end of the mating rod 47 away from the sleeve ring 46 is fixedly connected with an elastic telescopic rod 49.

[0029] An elastic plate 411 is fixedly connected to the inner surface of the cleaning pipe 45.

Both ends of the top elastic plate 411 are fixedly connected to the moving column 43. On both inner surfaces of the bottom elastic plate 411, elastic telescopic plates 412 are fixedly connected.

The internal cavity of the elastic telescopic plate 412 is communicated with the internal cavity of the elastic telescopic rod 49.

[0030] When working, when solar energy collection is required, the whole device can be moved to a designated outdoor location and the motor 36 is started. When the motor 36 is started, it drives the driving wheel 35 to rotate, and then the threaded tube 33 fixedly connected to the driven wheel 34 starts to rotate on the outer surface of the positioning rod 31. With the rotation of the threaded tube 33, under the action of the threaded connection, the second hinge seat 39 starts to move upward along the threaded tube 33, that is, the support rod 37 is pushed to rotate outward along the first hinge seat 32 through the connecting rod 38 hinged to the second hinge seat 39, and finally the support rod 37 is spread out horizontally, so that the photovoltaic panel 312 in the mounting plate 310 on the support rod 37 starts to face the sun for photovoltaic power generation, and the electric energy is stored in the storage battery 313. Among them, the photovoltaic panel 312 and the storage battery 313 are connected by a connecting wire. The electric energy generated by the photovoltaic panel 312 is first transmitted to the controller through the connecting wire. The controller will adjust the voltage and current output by the photovoltaic panel 312 according to the charging state of the storage battery 313. After the controller adjusts the electric energy transmitted by the photovoltaic panel 312 to appropriate voltage and current, it is transmitted to the storage battery 313 through the connecting wire for storage to ensure that the storage battery 313 can be charged safely and efficiently. By installing the mounting plate 310 in an openable and closable manner, the mounting plate 310 can be retracted when transportation is required, greatly reducing the space occupied during transportation and improving the transportation efficiency. At the same time, when encountering rainy, snowy or windy weather, the mounting plate 310 can also be closed, thereby greatly reducing the wind resistance directly received by the device and improving the installation stability of the device. Moreover, by installing the storage battery 313 on the second hinge seat 39, the storage battery 313 itself is in the air, and the working storage battery 313 is cooled by the natural wind, greatly improving the working stability of the storage battery 313, and distinguishing from the safety hazard problem caused by the sealed installation of the storage battery 313 in the current solar charging device. Since the top cover 315 is fixedly connected to the inner upper surface of the mounting plate 310 and the shielding film 314 is fixedly connected to the lower surface of the mounting plate 310, when the mounting plate 310 is unfolded for work, the space below the mounting plate 310 is in a shielded state through the cooperation of the top cover 315 and the shielding film 314, avoiding the problem that the storage battery 313 is directly irradiated by the sun and the temperature rises rapidly, reducing the service life. And when the mounting plate 310 is retracted, the threaded rod can be in a relatively sealed state through the mutual cooperation of the top cover 315 and the shielding film 314, and then the parts and the storage battery 313 of the device can be isolated from rain when the mounting plate 310 is retracted in rainy days, greatly improving the overall service life of the device. And by setting the bottom of the top cover 315 to be corrugated, the deformation force at the bottom of the top cover 315 can be greatly increased, thereby greatly extending the service life of the top cover 315 in a long-term deformed state. When the mounting plate 310 is retracted, the second hinge seat 39 moves downward, and then the top plate 316 is pulled downward by the pull rod, and then the extrusion bladder 319 is extruded.The squeezing bag 319 transmits its internal air pressure to the expansion groove 320 in the shielding film 314, so that when the mounting plate 310 is folded, the shielding films 314 between the adjacent ones expand to cushion the mounting plate 310, thereby preventing the mounting plates 310 from colliding with each other during the folding process and causing damage to the photovoltaic panel 312. When the second hinge seat 39 moves downward, the inner end of the connecting rod 38 will also move downward, thereby driving the pull rope 410 to move downward. When the pull rope 410 moves downward, it will begin to generate a pulling force on the matching rod 47, and then pull the moving column 43 through the ring 46 to start sliding in the first slide groove 41, and then start to clean the surface of the photovoltaic panel 312 through the outer surface of the cleaning tube 45. At the same time, with the synchronous change of the angle of the photovoltaic panel 312, the dust cleaned by the cleaning tube 45 begins to slide along the gradually inclined photovoltaic panel 312, and finally separates from the photovoltaic panel 312 through the cleaning groove 42, thereby realizing automatic cleaning of the photovoltaic panel 312 when the mounting plate 310 is folded in rainy and snowy weather. 2 for cleaning, ensuring that the photovoltaic panel 312 is always in a stable working state, and when the matching rod 47 moves, it squeezes the elastic telescopic rod 49, so that the elastic telescopic rod 49 transmits its internal air pressure to the elastic telescopic plate 412, and then the elastic telescopic plate 412 begins to expand, squeezing the two sides of the elastic plate 411 at the bottom, so that the elastic plate 411 at the bottom gradually tends to be horizontal and expands downward, thereby greatly increasing the contact area between the cleaning tube 45 and the photovoltaic panel 312, thereby greatly improving the cleaning efficiency of the photovoltaic panel 312, and when the elastic telescopic rod 49 is squeezed to the limit, it itself begins to slide on the bottom surface of the mounting plate 310, and then begins to drive the expanded cleaning tube 45 to clean the photovoltaic panel 312, so that after the photovoltaic panel 312 is expanded, the cleaning tube 45 is separated from the contact with the photovoltaic panel 312 through the retracted elastic plate 411, avoiding the problem of the cleaning tube 45 being in contact with the photovoltaic panel 312 for a long time when not working, causing damage to the photovoltaic panel 312.
