[0003] The traditional fixed support is designed in combination with a protective cover to achieve wind and sand protection by adding a metal or plastic protective cover outside the photovoltaic panel.

In addition, the high-speed sand particles in the desert area will accelerate the wear of the cover body and shorten its service life. Secondly, the protective cover forms a closed space after being closed, and the heat generated by the operation of the photovoltaic panel cannot be effectively dissipated, resulting in abnormal temperature rise of the panel body and accelerating the aging risk of the component. Thirdly, the cover body with poor light transmission will block the edge of the photovoltaic panel even if it is opened, and will also reduce the light efficiency of the photovoltaic panel. SUMMARY

[0029] Embodiment 1 Reference Figures 1-6 For the first embodiment of the present application, a folding mechanism 200 is provided to realize the folding of the photovoltaic panel 103 and reduce the damage caused by strong wind and the like.

[0030] The support frame 101 includes a support leg 102, and the top of the support frame 101 is provided with a photovoltaic panel 103; The support frame 101, the support leg 102 and the photovoltaic panel 103 are all provided with two groups and are arranged at different heights. The bottom of the photovoltaic panel 103 at the high position is not fixedly connected with the top of the support frame 101, and vice versa. The bottom of the photovoltaic panel 103 at the bottom is fixedly connected with the top of the support frame 101; The folding mechanism 200 includes a driving assembly 201 arranged at the bottom of the support frame 101 at the high position, and the surface of the driving assembly 201 is drivingly connected with a rotating part 202; The driving assembly 201 includes a fixed block 201a fixedly connected to the bottom of the support frame 101 at the high position, a first push rod 201b fixedly connected to the left side of the fixed block 201a, and a defective rack 201c drivingly connected to the output end of the first push rod 201b; The rotating part 202 includes a defective gear 202a engaged with the surface of the defective rack 201c, and a first connecting block 202b fixedly connected to the outer side of the defective gear 202a; A semi-circular fixing ring 203 is fixedly connected to the outer side of the photovoltaic panel 103 at the bottom, and the inner side of the semi-circular fixing ring 203 is rotatably connected to the outer side of the broken gear 202a. The inner side of the semi-circular fixing ring 203 is provided with an annular travel groove 204, and the inner side of the annular travel groove 204 is provided with an annular travel hole 205. The outer side of the first connecting block 202b extends through to the inner side of the annular travel groove 204 and is fixedly connected to the second connecting block 206. The opposite side of the second connecting block 206 is fixedly connected to the opposite side of the photovoltaic panel 103. The bottom of the broken rack 201c is provided with a support groove 207, and a support rod 208 is provided on the surface of the support groove 207. The other end of the support rod 208 is fixedly connected to the bottom of the fixing block 201a. A second push rod 209 is fixedly connected to the outer side of the lower support leg 102. A rotating block 210 is drivenly connected to the top of the second push rod 209. The outer side of the rotating block 210 is slidably connected to the surface of the extrusion groove 211. The extrusion groove 211 is opened at the bottom of the lower support frame 101. An adjustment groove 212 is provided on the inner side of the support frame 101 at the lower position, and the inner side of the adjustment groove 212 is slidably connected to the outer side of the support leg 102.

[0031] Specifically, the folding mechanism 200 is activated when a nighttime or strong wind warning signal is detected.

[0032] Furthermore, by energizing and retracting the first push rod 201b, the incomplete rack 201c is pulled to move horizontally along the support groove 207 at the top of the support rod 208. The support rod 208 assists in the movement of the incomplete rack 201c to prevent it from deviating during movement. During the movement, the incomplete rack 201c meshes with the incomplete gear 202a and drives the incomplete gear 202a to rotate along the inner side of the semi-circular fixed ring 203. The incomplete gear 202a drives the second connecting block 206 to slide along the annular stroke groove 204 through the first connecting block 202b, thereby driving the photovoltaic panel 103 at the high position to rotate around the semi-circular fixed ring 203 as the center, realizing the folding action towards the top of the photovoltaic panel 103 at the low position. After the photovoltaic panel 103 is folded, the second push rod 209 retracts, pulling the rotating block 210 to slide along the compression groove 211 at the bottom of the lower support frame 101. The inclined setting of the compression groove 211 converts the sliding of the rotating block 210 into a supporting force on the lower support frame 101. As the right side of the support frame 101 gradually moves downward, the left side of the support frame 101 will be affected by the gravity of the right side of the support frame 101, causing the support frame 101 to slide along the support leg 102 in the adjustment groove 212 to adjust the tilt angle. Finally, the folded photovoltaic panel 103 is perpendicular to the ground, greatly reducing the windward area and improving wind resistance.

[0033] It should be noted that the detector used for detecting nighttime or strong winds can be installed on one side of the support frame 101 or the support leg 102.

[0034] Example 2 Reference Figures 1-6 In the second embodiment of the present invention, a cleaning mechanism 300 is provided to clean the photovoltaic panel 103 when it is folded.

[0035] The cleaning mechanism 300 includes an air injection assembly 301 disposed on the top of the photovoltaic panel 103, and an air jet component 302 is connected to the outside of the air injection assembly 301. The gas injection assembly 301 includes a clamping plate 301a fixedly connected to the top of the photovoltaic panel 103 at the high and low positions. The top of the clamping plate 301a is fixedly connected to an annular airbag 301b and an elastic member 301c, respectively. The elastic member 301c is opened around the outside of the annular airbag 301b. The jet component 302 includes jet pipes 302a connected to the left and right sides of the annular airbag 301b. The inner side of the jet pipes 302a is connected to several inclined jet heads 302b, and the several jet heads 302b are used to perform jet cleaning on the surface of the photovoltaic panel 103.

[0036] Specifically, when the high-level photovoltaic panel 103 folds towards the low-level photovoltaic panel 103, its bottom edge gradually approaches the annular airbag 301b at the top of the low-level photovoltaic panel 103. As the folding action progresses, the high-level photovoltaic panel 103 compresses the annular airbag 301b, causing the air pressure inside the annular airbag 301b to increase. The high-pressure air is diverted through the jet pipes 302a on the left and right sides of the annular airbag 301b and finally ejected from several tilted jet heads 302b. The tilt angle of the jet heads 302b faces the surface of the photovoltaic panel 103, forming an airflow along the photovoltaic panel 103, blowing away the sand and debris attached to the surface of the photovoltaic panel 103, thus achieving simultaneous folding and cleaning.

[0037] Furthermore, after the cleaning is completed, as the photovoltaic panel 103 at the top is deployed again, the annular airbag 301b is reset under the elastic force of the outer elastic element 301c, restoring its initial shape and drawing in outside air to prepare for the next cleaning.

[0038] It should be noted that the air intake end of the annular airbag 301b can be located on one side of the annular airbag 301b.

[0039] The remaining structure is the same as that in Example 1.

[0040] Example 3 Reference Figures 1-6This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a photovoltaic support device for emerging energy.

[0041] First, the staff pre-installs the sensor for detecting the intensity of light at night on the side of the low support frame 101 or on the top of the support leg 102. The sensor is electrically connected to the control module of the folding mechanism 200 and the cleaning mechanism 300 to form an automatic triggering function. When the sensor detects that the ambient light intensity is lower than a preset threshold or the wind speed reaches a preset warning value, the control module controls the first push rod 201b and the second push rod 209 of the folding mechanism 200 to start. At this time, the first push rod 201b, located at the bottom of the high support frame 101, is energized and begins to retract. Its output end pulls the broken rack 201c to move horizontally to the left along the support groove 207 at the top of the support rod 208. The support rod 208 makes contact with the broken rack 201c through the support groove 207, thus controlling the movement trajectory of the broken rack 201c. The horizontal constraint effectively prevents it from shifting up and down or swaying left and right due to uneven force during horizontal movement. During the movement, the tooth surface of the broken rack 201c meshes with the tooth surface of the broken gear 202a. Since the outer side of the broken gear 202a is rotatably connected to the inner side of the semi-circular fixing ring 203 fixed to the outer side of the photovoltaic panel 103 at the lower position, the horizontal force of the broken rack 201c is converted into the rotational force of the broken gear 202a, which drives the broken gear 202a to rotate along the inner side of the semi-circular fixing ring 203. When the broken gear 202a rotates, the first connecting block 202b fixed on its outer side rotates synchronously. The outer side of the first connecting block 202b extends through the annular stroke hole 205 inside the semi-circular fixing ring 203 into the annular stroke groove 204 and is fixedly connected to the second connecting block 206. Therefore, when the first connecting block 202b rotates, it can synchronously drive the second connecting block 206 to rotate. At the same time, the second connecting block 206 is fixed to the side of the high photovoltaic panel 103. Therefore, the rotation of the first connecting block 202b drives the second connecting block 206 and transmits it to the high photovoltaic panel 103, so that the high photovoltaic panel 103 slowly folds towards the top of the low photovoltaic panel 103 with the center of the semi-circular fixing ring 203 as the axis of rotation. During the folding process of the high-level photovoltaic panel 103, its bottom edge gradually approaches and squeezes the annular airbag 301b set on the top of the low-level photovoltaic panel 103. As the angle between the high-level photovoltaic panel 103 and the low-level photovoltaic panel 103 gradually decreases, the edge of the photovoltaic panel 103 contacts the surface of the annular airbag 301b and begins to compress. As the angle between the photovoltaic panels 103 gradually decreases, the compressive force gradually increases, and the air inside the annular airbag 301b is rapidly compressed. The air inside the annular airbag 301b is diverted through the jet pipes 302a connected on the left and right sides of the annular airbag 301b and delivered to the jet pipes 302a on the top of the photovoltaic panel 103. Finally, it is ejected from several inclined jet heads 302b connected to the inside of the jet pipes 302a, which can blow away sand, fallen leaves, fluff and other debris from the surface of the photovoltaic panel 103, preventing debris from accumulating at night or in strong winds. When the high-mounted photovoltaic panel 103 is completely folded to the top of the low-mounted photovoltaic panel 103, and the surfaces of the two are in contact, the first push rod 201b stops retracting and maintains its current state, while the second push rod 209 begins to retract after being energized. The rotating block 210, which is connected to the top of the second push rod, slides downward along the inclined extrusion groove 211 at the bottom of the low-mounted support frame 101 under the action of tension. Since the extrusion groove 211 has an inclined structure with the bottom on the left and the top on the right, the sliding of the rotating block 210 will generate an upward supporting force on the inner wall of the extrusion groove 211. As the right side of the support frame 101 gradually moves downward, the left side of the support frame 101 will be affected by the gravity of the right side of the support frame 101, causing the support frame 101 to slide along the support leg 102 in the adjustment groove 212 to adjust the tilt angle. Finally, the photovoltaic panel 103 after folding is perpendicular to the ground, which greatly reduces the windward area and improves the wind resistance.

[0042] In summary, by setting up the folding mechanism 200 and the cleaning mechanism 300, the windward surface area can be significantly reduced, the wind resistance in special environments can be improved, and the surface of the photovoltaic panel 103 can be cleaned of sand and dust during folding.
