[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The exemplary embodiments according to the present application will be described in detail below with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described here.

[0038] The embodiment of the present application provides a photovoltaic bracket, which is used to protect photovoltaic panels from damage in severe convective weather, enhance the ability of photovoltaic panels to resist severe convective weather, increase the service life of photovoltaic panels, and broaden the application scope of photovoltaic panels.

[0039] Figure 1 A schematic structural diagram of a photovoltaic bracket 100 provided in an embodiment of the present application is shown. Figure 2 A schematic diagram showing another state of the photovoltaic bracket 100 provided in an embodiment of the present application is shown. Figure 1 and Figure 2 As shown, the photovoltaic support 100 includes: a clamping member 110, a supporting member and a limiting mechanism.

[0040] The clamping member 110 clamps the photovoltaic panel (not shown in the figure) from the side of the photovoltaic panel; the clamping member 110 is used to limit and fix the photovoltaic panel, and the photovoltaic panel can be rotated by rotating the clamping member 110.

[0041] The support member is rotatably connected to the clamping member 110; the support member is used to support and fix the photovoltaic panel at a preset position to install the photovoltaic panel so that the photovoltaic panel can absorb light energy.

[0042] The support member in the embodiment of the present application can be rotatably connected to the clamping member 110, so that the clamping member 110 can drive the photovoltaic panel to rotate relative to the support member.

[0043] In some other exemplary scenarios, the configuration of the structure can facilitate the adjustment of the angle of the photovoltaic panel so that the photovoltaic panel can absorb light energy at a suitable angle to improve the absorption rate of light energy.

[0044] The limiting mechanism is used to limit the clamping member 110 to rotate relative to the support member to a first preset position or a second preset position; the first preset position is the position where the front of the photovoltaic panel faces the sunlight, and the second preset position is the position where the back of the photovoltaic panel faces upward.

[0045] The photovoltaic bracket 100 provided in the embodiment of the present application is used to protect photovoltaic panels and prevent the photovoltaic panels from being damaged by severe convective weather.

[0046] In the embodiment of the present application, under normal weather conditions, the limiting mechanism limits the clamping member 110 to a first preset position relative to the support member; under severe convective weather conditions, the limiting mechanism limits the clamping member 110 to a second preset position relative to the support member.

[0047] The first preset position is the position where the front of the photovoltaic panel faces the sunlight. In order to absorb light energy more efficiently, the first preset position is set based on the sunlight exposure; it is usually 30°-60° away from the ground or horizontal plane, and more usually 45°. The closer the angle is to the sunlight, the more susceptible it is to the positive resistance of the strong wind in the case of strong wind. The greater the resistance force on the photovoltaic panel, the more susceptible it is to damage, and the photovoltaic bracket 100 is more likely to be twisted or broken.

[0048] The second preset position is the position where the back of the photovoltaic panel faces upward, which can be approximately parallel to the ground to prevent strong winds from damaging the photovoltaic panel and avoid strong winds from directly hitting the photovoltaic panel. In addition, in the case of heavy rain or hail, rain or hail hits the back glass of the photovoltaic panel, and the damage to the back glass is not likely to affect the photovoltaic panel's absorption and conversion of light, so the photovoltaic panel is protected calmly to reduce damage and extend the service life of the photovoltaic panel.

[0049] In the case of severe convective weather, the embodiment of the present application moves the photovoltaic panel from a first preset position relative to the support member to a second preset position so that the back of the photovoltaic panel faces upward, thereby protecting the photovoltaic panel from damage; thereby enhancing the ability of the photovoltaic panel to resist severe convective weather, increasing the service life of the photovoltaic panel, and broadening the scope of application of the photovoltaic panel.

[0050] In the embodiment of the present application, the rotation of the clamping member 110 relative to the support member can be manually rotated. When the strong convective weather is predicted to come, the clamping member 110 is rotated so that the clamping member 110 is limited to the second preset position relative to the support member; in addition, the rotation of the clamping member 110 relative to the support member can also be automatic rotation. An exemplary embodiment of automatic rotation is provided below.

[0051] In one embodiment, the clamping member 110 includes a first clamping plate and a second clamping plate, which are respectively clamped on opposite sides of the photovoltaic panel; the supporting member includes a first bracket and a second bracket, the first bracket is rotatably connected to the first clamping plate, and the second bracket is rotatably connected to the second clamping plate.

[0052] The first clamping plate and the second clamping plate can be respectively mounted on the opposite sides of the photovoltaic panel; the first clamping plate / the second clamping plate is provided with a groove for the photovoltaic panel to pass through, and the two opposite sides of the photovoltaic panel pass through the grooves of the first clamping plate and the second clamping plate respectively, so that rotating the first clamping plate / the second clamping plate can drive the photovoltaic panel to rotate.

[0053] The first clamping plate and the second clamping plate may be fixedly bonded or welded to opposite sides of the photovoltaic panel, so that rotating the first clamping plate / the second clamping plate can drive the photovoltaic panel to rotate.

[0054] The rotatable connection between the clamping member 110 and the supporting member may be a hinge, and the clamping member 110 and the supporting member are both sleeved on a rotating shaft so that the clamping member 110 rotates around the rotating shaft.

[0055] In one example, by adding a limit spring at the hinge position of the clamp 110 and the support, the clamp 110 is limited to rotate to the first preset position or the second preset position relative to the support. For example, when the limit spring is tightened, the clamp 110 is at the first preset position relative to the support; when the limit spring is loosened, the clamp 110 rotates from the first preset position relative to the support to the second preset position relative to the support; thus, the automatic rotation between the clamp 110 and the support is achieved through the action of the limit spring and in cooperation with other controllers 1334.

[0056] In the embodiment of the present application, two brackets are used to support the photovoltaic panel on both sides respectively, so that the photovoltaic panel tends to be balanced and stable, and space is provided for the rotation of the photovoltaic panel.

[0057] In one embodiment, the clamping member 110 includes a clamping frame, and the photovoltaic panel is mounted in the clamping frame; the supporting member includes a first bracket and a second bracket, and the first bracket and the second bracket are rotatably connected to two opposite sides of the clamping frame respectively.

[0058] In the embodiment of the present application, the clamping member 110 is a frame structure, and the photovoltaic panel can be clamped in the clamping frame, or one side of the clamping frame can be an opening. After the photovoltaic panel is installed, the opening is sealed to achieve the photovoltaic panel being mounted in the clamping frame.

[0059] In the embodiment of the present application, two brackets are used to support the photovoltaic panel on both sides, so that the photovoltaic panel tends to be balanced and stable, and provides space for the rotation of the photovoltaic panel.

[0060] In one embodiment, the first bracket or the second bracket includes: a support plate 121 , a column 122 and a connecting rod 123 .

[0061] The support plate 121 is rotatably connected to the clamping member 110; the support plate 121 is a component connected to the clamping member 110. The upright column 122 and the connecting rod 123 are used to support the support plate 121, thereby supporting the photovoltaic panel.

[0062] The column 122 is fixed at a preset installation position; the preset installation position is the position where the photovoltaic panel is installed, so that the photovoltaic panel can absorb sunlight well. The preset installation position can be the ground or the roof.

[0063] In one example, a mounting plate 140 may be installed at a preset installation position so that the column 122 may be fixed on the mounting plate 140 , thereby avoiding a situation where the column 122 is difficult to be directly installed on the ground or the roof.

[0064] In order to ensure the stability of the photovoltaic support 100, the column 122 can be made of a relatively strong material or a relatively thick material to stably support the photovoltaic panel.

[0065] The two ends of the connecting rod 123 are fixedly connected to the column 122 and the support plate 121. The connecting rod 123 can be connected to the column 122 and the support plate 121 at an angle to make the structure of the photovoltaic bracket 100 more stable. Figure 1 Or the angle shown in 2.

[0066] The first bracket or the second bracket provided in the embodiment of the present application can stably support the photovoltaic panel and realize the rotation of the photovoltaic panel.

[0067] In one embodiment, the limiting mechanism includes a wind sensor 131, a rotating device and a control device.

[0068] The wind sensor 131 is used to detect the wind force in the environment; as long as it can detect the wind force and send a signal. The wind sensor 131 can detect the wind force in real time and send a signal at a preset frequency; it can also detect a risk signal when the wind force exceeds a specified threshold and send the risk signal. The risk signal can be a level signal including multiple different risk levels.

[0069] The rotating device is used to drive the clamping member 110 to rotate to the first preset position or the second preset position relative to the supporting member.

[0070] The control device is used to start the rotating device to drive the clamping member 110 to rotate from the first preset position to the second preset position relative to the support member when the wind force value exceeds the preset threshold.

[0071] In the embodiment of the present application, when the control device receives a signal, it can start the rotating device according to the signal to drive the clamping member 110 to rotate from the first preset position to the second preset position relative to the support member. After the strong convective weather, the clamping member 110 can be manually rotated from the second preset position to the first preset position relative to the support member.

[0072] In the embodiment of the present application, the limiting mechanism may be separately provided on the first bracket or the second bracket, or the limiting mechanism of any implementation aspect of the above-mentioned embodiment may be provided on both the first bracket and the second bracket.

[0073] In one embodiment, the rotating device includes: a traction unit and a transmission unit.

[0074] The traction unit includes a gravity block 1321 and a traction belt 1322 , and a first end of the traction belt 1322 is fixedly connected to the gravity block 1321 .

[0075] The transmission unit includes a first transmission belt 1323 and a first gear 1324 and a second gear 1325 that are meshed with each other; the second end of the traction belt 1322 is fixed to the hub of the first gear 1324 and is wrapped around the hub of the first gear 1324 for a preset number of times; the preset number of times is adapted to the angle at which the clamping member 110 rotates from the first preset position to the second preset position relative to the support member; the first transmission belt 1323 is sleeved on the hubs of the first transmission wheel 1326 and the second gear 1325, and the first transmission wheel 1326 is sleeved on the rotating shaft that is rotatably connected to the support member and the clamping member 110.

[0076] like Figure 1 , the gravity block 1321 can slide down based on gravity, the traction belt 1322 drives the first gear 1324 to rotate clockwise, and the second gear 1325 rotates counterclockwise synchronously based on the meshing with the first size; the first transmission wheel 1326 rotates counterclockwise synchronously driven by the first transmission belt 1323, thereby driving the photovoltaic panel to rotate counterclockwise, and rotates to Figure 2 The state shown is to combat severe convective weather.

[0077] The preset number of turns may be a length that allows the gravity block 1321 to fall to a length at which the clamping member 110 rotates from the first preset position to the second preset position relative to the support member.

[0078] In one example, the length of the weight block 1321 falling to the second preset position from which the clamping member 110 rotates relative to the support member from the first preset position is equal to the height of the weight block 1321. When the weight block 1321 falls to the ground or the mounting plate, the clamping member 110 rotates relative to the support member from the first preset position to the second preset position.

[0079] In one embodiment, the first end of the traction belt 1322 is located on a side of the first gear 1324 that is away from the second gear 1325 .

[0080] refer to Figure 1 , the photovoltaic panel may be Figure 1 As shown, it is arranged toward the upper left, and it may also be arranged toward the upper right; the first gear 1324 may be located as shown Figure 1 The side of the second gear 1325 facing away from the photovoltaic panel may also be located on the side of the second gear 1325 close to the photovoltaic panel. In these cases, it is only necessary for the first end of the traction belt 1322 to be located on the side of the first gear 1324 facing away from the second gear 1325, so that when the gravity block 1321 falls, the photovoltaic panel can be rotated to the second preset position at the minimum angle.

[0081] In one embodiment, the control device includes: a guide rail 1331 , an electric telescopic rod 1332 , and a controller 1334 .

[0082] The guide rail 1331 is used to guide the sliding of the gravity block 1321; the structure of the guide rail 1331 is compatible with the shape of the gravity block 1321; by guiding the gravity block 1321 through the guide rail 1331, it is convenient to limit the gravity block 1321, and at the same time ensure that the gravity block 1321 is not affected by strong convective weather and causes disorderly falling, affecting the counteracting effect of the photovoltaic bracket 100.

[0083] like Figure 1 As shown, the electric telescopic rod 1332 is arranged near the top of the guide rail 1331, the extension direction of the output end 1333 of the electric telescopic rod 1332 forms a preset angle with the guide rail 1331, and the output end 1333 of the electric telescopic rod 1332 abuts against the gravity block 1321; the output end 1333 of the electric telescopic rod 1332 abuts against the gravity block 1321, and may abut against the middle of the gravity block 1321, or may abut against the bottom of the gravity block 1321. The output end 1333 of the electric telescopic rod 1332 abuts against the middle of the gravity block 1321, providing a buffer when the gravity block 1321 starts to fall.

[0084] The controller 1334 is used to control the movement of the electric telescopic rod 1332 . The controller 1334 controls the output end 1333 of the electric telescopic rod 1332 to retract based on the signal of the wind sensor 131 , so that the gravity block 1321 slides down.

[0085] In the present application embodiment, Figure 1 As shown, the guide rail 1331 can be arranged near the first column 122, or can be arranged on the first column 122. Since the column 122 is relatively thick, it can be used for fixed connection of other components. For example, the first gear 1324 and the second gear 1325 can be arranged on the column 122 through a support rod. The controller 1334 and the telescopic rod 1332 can also be fixedly installed on the side wall of the column 122.

[0086] In one embodiment, the control device further includes an emergency power supply 1335 for providing emergency power to the controller 1334. The controller 1334 is powered by electricity generated by the photovoltaic panel. When encountering strong convective weather and the photovoltaic panel cannot supply power, the emergency power supply 1335 is used to supply power to ensure that the photovoltaic bracket 100 can work in strong convective weather to protect the photovoltaic panel. The emergency power supply 1335 can be a storage power supply to store the electric energy provided by the photovoltaic panel.

[0087] In one embodiment, there are two clamping members 110, and one clamping member 110 clamps one photovoltaic panel; both clamping members 110 are rotatably connected to the support member; the transmission unit also includes a second transmission belt 1328 and a second transmission wheel 1327; the second transmission wheel 1327 is sleeved on the rotating shaft of the support member and the other clamping member 110; the second transmission belt 1328 is sleeved between the first transmission wheel 1326 and the second transmission wheel 1327.

[0088] like Figure 1 As shown, the second transmission wheel 1327 drives the other clamping member 110 to rotate under the drive of the second transmission belt 1328, so that the photovoltaic panel clamped by the other clamping member 110 can resist strong convective weather. It can be known that based on this structure, more transmission belts and transmission wheels can be set to achieve protection of more photovoltaic panels, and these implementation schemes are all within the protection scope of this application.

[0089] The embodiment of the present application supports two photovoltaic panels at the same time through one photovoltaic bracket 100 , and provides protection for the two photovoltaic panels against severe convective weather at the same time, thereby saving materials and improving the utilization rate of the photovoltaic bracket 100 .

[0090] Other components of the photovoltaic bracket 100 in the above embodiment may adopt various technical solutions known to ordinary technicians in this field now and in the future, and will not be described in detail here.
