[0024] like Figures 1 to 5As shown, the photovoltaic power generation device with a protective structure comprises: a photovoltaic power generation device body 1 and a protective structure 2; the photovoltaic power generation device 1 comprises an inclined photovoltaic panel 11, and the protective structure 2 comprises a housing tube 21, two mounting rods 22, a slide 23, a protective assembly 24, a counterweight 25, a driving assembly 26 and a rotating shaft 27; the two mounting rods 22 are respectively fixedly mounted on both sides of the photovoltaic power generation device body 1, and are used to provide support for the protective structure 2. The slide 23 is fixedly mounted on the mounting rods 22, and is consistent with the tilt direction of the photovoltaic panel 11, and is used to guide the sliding movement of the protective assembly 24. The housing tube 21 is fixedly mounted on the top of the two mounting rods 22, and is used to accommodate the rotating shaft 27 and protect it from external influences. The driving assembly 26 is fixedly mounted on the mounting rods 22, and its output end is connected to one end of the rotating shaft 27, and is used to drive the rotating shaft 27 to rotate in two directions. The rotating shaft 27 is rotatably mounted inside the housing tube 21 through a supporting component, and is connected to the waterproof cloth 243 of the protective assembly 24. The protection assembly 24 includes a connecting beam 241, a slider 242 and a waterproof cloth 243. The two ends of the connecting beam 241 are respectively connected to the slider 242, which is slidably installed inside the slide 23 to drive the protection assembly 24 to slide along the slide 23. One end of the waterproof cloth 243 is fixedly connected to the connecting beam 241, and the other end penetrates into the interior of the accommodating tube 21 and is connected to the rotating shaft 27 to achieve unfolding or reeling under the drive of the rotating shaft 27. Counterweight blocks 25 are provided at both ends of the connecting beam 241 at one end of the waterproof cloth 243 away from the rotating shaft 27. The counterweight blocks 25 are slidably installed in the slide 23 to drive the protection assembly 24 to slide downward under the action of gravity and provide stable support.

[0025] In heavy rain or hail weather, the driving assembly 26 is started, and the driving assembly 26 drives the rotating shaft 27 to rotate in the first direction, the rotating shaft 27 releases the protective assembly 24, and the waterproof cloth 243 is unfolded under the action of gravity. The counterweight block 25 drives the protective assembly 24 to slide downward along the slide groove 23 to completely cover the photovoltaic panel 11. The connecting beam 241 provides rigid support during the unfolding process of the protective assembly 24 to ensure the tension and impact resistance of the waterproof cloth 243.

[0026] When the weather clears up, the driving assembly 26 drives the rotating shaft 27 to rotate in the second direction, and the rotating shaft 27 reels the protective assembly 24. During this process, the slider 242 slides upward in the slide groove 23, and the waterproof cloth 243 is gradually retracted into the housing tube 21, completing the reset of the protective structure and restoring the normal working state of the photovoltaic panel 11.

[0027] The two mounting rods 22 are fixedly connected to the photovoltaic power generation device body 1, the slide 23 is fixedly connected to the mounting rods 22, the accommodating tube 21 is fixedly connected to the mounting rods 22, the driving assembly 26 is installed on the mounting rods 22, the rotating shaft 27 is rotatably installed inside the accommodating tube 21, one end of the rotating shaft 27 passes through the accommodating tube 21 and is connected to the driving assembly 26; the protective assembly 24 includes a connecting beam 241, a slider 242 and a waterproof cloth 243; both ends of the connecting beam 241 are connected to the slider 242, the slider 242 is slidably installed inside the slide 23, the waterproof cloth 243 is connected to the connecting beam 241, one end of the waterproof cloth 243 extends into the interior of the accommodating tube 21 and is fixedly connected to the rotating shaft 27, and the two ends of the connecting beam 241 at one end of the waterproof cloth 243 away from the rotating shaft 27 are connected to the counterweight 25, and the counterweight 25 is slidably installed in the slide 23.

[0028] In case of heavy rain or hail, the driving assembly 26 is started, and the driving assembly 26 is used to drive the rotating shaft 27 to rotate in the first direction, and the rotating shaft 27 releases the protective assembly 24. Since the photovoltaic panel 1 and the chute 23 are both in an inclined setting, the counterweight 25 slides down under the action and drags the waterproof cloth 243 to cover the photovoltaic panel 11. At the same time, the connecting beam 241 provides support and provides rigid support for the waterproof cloth 243. On sunny days, the driving assembly 26 is used to drive the rotating shaft 27 to rotate in the second direction, and the rotating shaft 27 rotates to reel up the protective assembly 24, and the photovoltaic panel 1 is no longer covered.

[0029] In this embodiment, the driving assembly 26 includes a motor 261, a worm 262 and a worm wheel 263. The motor 261 is fixedly mounted on the containing tube 21, the output end of the motor 261 is connected to the worm 262, the worm 262 is meshedly connected to the worm wheel 263, and the worm wheel 263 is connected to the rotating shaft 27. By starting the motor 261, the motor 261 drives the worm 262 to rotate, the worm 262 further drives the worm wheel 263 to rotate, and the rotation of the worm wheel 263 drives the rotating shaft 27 to rotate, thereby applying a driving force to the rotating shaft 27, and completing the unfolding or reeling operation of the protective assembly 24.

[0030] In this embodiment, the photovoltaic power generation device body 1 also includes a support frame 12 for supporting the photovoltaic panel 11 in an inclined state. The design of the support frame 12 can ensure that the photovoltaic panel 11 receives sunlight at the optimal angle, thereby improving the efficiency of photovoltaic power generation. The support frame 12 specifically includes a plurality of bases 121, a support rod assembly 122 and a plurality of connecting rods 123. The base 121 is fixed to the ground to provide basic support for the entire device; the support rod assembly 122 is fixedly connected to the base 121 to keep the connecting rod 123 in a stable position; a plurality of photovoltaic panels 11 are fixedly connected to the support rod assembly 122 through the connecting rod 123, thereby forming a stable photovoltaic power generation module.

[0031] In this embodiment, in order to ensure that the protection component 24 can slide smoothly, a guide surface 2421 is provided at one end of the slider 242. The guide surface 2421 can effectively guide the slider 242 to slide into the inside of the slide groove 23 by providing a specific inclined surface structure, thereby avoiding the problem of the slider 242 being stuck during the sliding process, thereby improving the movement stability of the protection component 24.

[0032] Through the above design, the driving component 26 of this embodiment realizes efficient and stable driving of the rotating shaft 27, and the support frame 12 ensures that the photovoltaic panel 11 is in the best working state. At the same time, the guide surface 2421 design of the slider 242 further optimizes the movement performance of the protective component 24, and the overall device function is more complete and suitable for a variety of application scenarios.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
