The photovoltaic bracket uses the arrangement of support bars and gears to enable the support bars to move with the normal flipping of the frame. When strong winds occur, the locking mechanism is controlled to lock the support bars through the gears so that the support bars support the frame to improve the overall wind resistance of the photovoltaic bracket. However, when the locking mechanism locks the support bars through the gears so that the support bars support the frame, since the frame is in an inclined state, the contact area between the photovoltaic panels in the inclined state and the strong wind is large, that is, the resistance of the strong wind on the photovoltaic panels is large, resulting in The structure of the photovoltaic bracket is still easily damaged; although when strong winds occur, the photovoltaic bracket can control the transmission mechanism to change the photovoltaic panel from an inclined state to a horizontal state through the frame, and then control the locking mechanism to lock the support bar through the gear so that the support bar supports the frame, which can reduce the resistance of the strong wind on the photovoltaic panel, but the reaction time required for this method is relatively long; at the same time, when strong winds occur, since the sun is always in a moving state, while the photovoltaic panel remains stationary, after the strong wind passes, the transmission mechanism needs to readjust the position of the photovoltaic panel through the frame, and after the strong wind passes, the photovoltaic panel cannot be quickly aligned with the sunlight.

[0028] The power assembly includes an arc-shaped rack 111, a driving gear 112 and a motor 113; the arc-shaped slide plate 5 is fixedly connected to the arc-shaped rack 111; the base frame 1 is bolted to the motor 113; the output shaft of the motor 113 is fixedly connected to the driving gear 112, and the driving gear 112 is meshed with the arc-shaped rack 111.

[0029] The pushing assembly includes an electric push rod 121 and a pushing plate 122; the base frame 1 is bolted to two electric push rods 121; the telescopic parts of all the electric push rods 121 are fixedly connected to the pushing plate 122, and the pushing plate 122 is used to keep the mounting plate 3 and the parts connected thereto in a horizontal state.

[0030] It also includes a shielding component; the mounting plate 3 is connected to two shielding components distributed front and back; the shielding component is composed of an electric slider 131, a pulling plate 132, a long rod 133, a shielding film 134 and a motor 135; the mounting plate 3 is slidably connected to two electric sliders 131 distributed left and right; all electric sliders 131 are commonly fixedly connected to the pulling plate 132; the mounting plate 3 is rotatably connected to the long rod 133; the long rod 133 is rolled up with a shielding film 134 for shielding the photovoltaic panel 4, and the shielding film 134 is fixedly connected to the pulling plate 132; the mounting plate 3 is bolted to the motor 135, and the output shaft of the motor 135 is fixedly connected to the long rod 133.

[0031] The push plate 122 is provided with a buffer pad 12201 , and the buffer pad 12201 is made of rubber.

[0032] The following description is based on the figure as the viewing angle, wherein the side of the chassis 1 marked thereon is the front side;

[0033] The specific working of the present invention is as follows: Under normal circumstances, the position of sunlight is sensed by the light sensor 8, and the detected position information is transmitted to the controller, and the motor 113 is controlled by the controller to work. From the front to the back, the output shaft of the motor 113 drives the mounting plate 3 and the parts connected thereto to rotate around the connection between the rotating shaft rod 2 and the base frame 1 through the driving gear 112, the arc rack 111, the arc sliding plate 5, the arc spring member 7 and the arc supporting plate 6, so that the photovoltaic panel 4 remains aligned with the sunlight.

[0034] When the wind speed sensor 9 detects strong winds, the wind speed sensor 9 will transmit the detected information to the controller, and the controller will control the electric push rod 121 to work, so that the telescopic part of the electric push rod 121 pushes the pushing plate 122 to move upward until the upper surface of the pushing plate 122 is completely in contact with the mounting plate 3. During this process, when the pushing plate 122 is in contact with the mounting plate 3, the mounting plate 3 and the parts connected thereto will rotate around the connection between the rotating shaft rod 2 and the base frame 1 under the push of the pushing plate 122. When the pushing plate 122 is in full contact with the mounting plate 3, the mounting plate 3 and the parts connected thereto will remain in a horizontal state, thereby reducing the contact area between the strong wind and the photovoltaic panel 4.

[0035] It should be noted that, in the process of the push plate 122 pushing the mounting plate 3 and the parts connected thereto to rotate, when the mounting plate 3 is in a position such as Figure 1 In the inclined state with the left side facing downward and the right side facing upward, since the arc-shaped slide plate 5, the arc-shaped support plate 6 and the rotating shaft rod 2 are all arranged concentrically, during the rotation of the mounting plate 3 and the parts connected thereto, the left arc-shaped support plate 6 will be pulled out from the arc-shaped slide plate 5 driven by the mounting plate 3 and stretch the left arc-shaped spring member 7, while the right arc-shaped support plate 6 will be inserted into the arc-shaped slide plate 5 under the push of the mounting plate 3 and compress the right arc-shaped spring member 7. When the mounting plate 3 and the parts connected thereto are kept in a horizontal state, the arc-shaped support plates 6 on both sides will be as shown in FIG. Figure 1 The state shown changes to Figure 6In the state shown, on the contrary, when the mounting plate 3 is in an inclined state with the left side facing upward and the right side facing downward, during the process of the pushing plate 122 pushing the mounting plate 3 and the parts connected thereto to rotate, the left arc-shaped support plate 6 will be inserted into the arc-shaped sliding plate 5 under the push of the mounting plate 3, and the right arc-shaped support plate 6 will be pulled out from the arc-shaped sliding plate 5 driven by the mounting plate 3, then the arc-shaped sliding plate 5 and the arc-shaped support plate 6 will not affect the pushing plate 122 pushing the mounting plate 3 and the parts connected thereto to rotate; when the wind speed sensor 9 detects that the strong wind has ended, the telescopic portion of the electric push rod 121 is controlled to drive the pushing plate 122 away from the mounting plate 3, and when the pushing plate 122 is away from the mounting plate 3, the arc-shaped spring member 7 in compression and tension will pass through the corresponding arc-shaped support plate 6 The mounting plate 3 and the parts connected thereto are pushed to rotate around the connection between the rotating shaft rod 2 and the base frame 1, so that the mounting plate 3 and the parts connected thereto are restored to the inclined state before the strong wind. In this way, the arc-shaped sliding plate 5, the arc-shaped supporting plate 6, the arc-shaped spring member 7 and the pushing assembly are arranged so that when the wind speed sensor 9 detects a strong wind, the mounting plate 3 and the parts connected thereto can be kept in a horizontal state under the action of the pushing plate 122, so as to prevent the problem in the prior art that, when the locking mechanism locks the supporting bar through the gear so that the supporting bar supports the frame, due to the tilted state of the frame, the contact area between the photovoltaic panel 4 in the tilted state and the strong wind is large, that is, the resistance exerted by the strong wind on the photovoltaic panel 4 is large, resulting in the structure of the photovoltaic bracket still being easily damaged.

[0036] It should be noted that the mounting plate 3 is in a Figure 1When the inclined state with the left side facing downward and the right side facing upward becomes a horizontal state, the left arc-shaped support plate 6 will be pulled out of the arc-shaped slide board 5 driven by the mounting plate 3, and the right arc-shaped support plate 6 will be inserted into the arc-shaped slide board 5 under the push of the mounting plate 3. Under this condition, when the arc-shaped slide board 5 continues to rotate clockwise, the part of the left arc-shaped support plate 6 inserted into the arc-shaped slide board 5 will gradually increase, and the part of the right arc-shaped support plate 6 inserted into the arc-shaped slide board 5 will gradually decrease. When the mounting plate 3 is in a horizontal state, the movement of the arc-shaped slide board 5 will not be restricted by the arc-shaped support plate 6. When the mounting plate 3 is in a horizontal state, the light sensor 8 continues to sense The controller controls the position of the sunlight and the motor 113 to work, so that the output shaft of the motor 113 can continue to drive the arc-shaped sliding board 5 to move on the base frame 1 through the driving gear 112 and the arc-shaped rack 111 in sequence. After the pushing plate 122 moves away from the mounting plate 3, the mounting plate 3 and the parts connected thereto are pushed by the arc-shaped supporting plate 6 to restore to the inclined state before the strong wind, and the photovoltaic panel 4 will be directly aligned with the sunlight. This avoids the problem in the prior art that when a strong wind occurs, the sun is always in a moving state, while the photovoltaic panel 4 remains stationary. Therefore, after the strong wind passes, the transmission mechanism needs to readjust the position of the photovoltaic panel 4 through the frame, resulting in the photovoltaic panel 4 being unable to quickly align with the sunlight.

[0037] Furthermore, considering that when strong winds blow, since a large amount of dust is carried in the strong winds and the photovoltaic panel 4 is in a horizontal state, a large amount of dust will fall onto the surface of the photovoltaic panel 4, thereby affecting the normal power generation of the photovoltaic panel 4; therefore, when strong winds blow, the output shafts of the two motors 135 are controlled to unwind the shielding film 134 through the corresponding long rods 133, and at the same time, the four electric sliders 131 are controlled to drive the corresponding two pulling plates 132 to approach each other, so that the two pulling plates 132 drive the corresponding shielding films 134 to approach each other, then when the two pulling plates 132 contact each other, the two shielding films 134 will shield the photovoltaic panel 4, making it difficult for the dust in the strong wind to fall onto the surface of the photovoltaic panel 4, and when the strong wind ends, according to the above-mentioned opposite operation, the two shielding films 134 will no longer shield the photovoltaic panel 4, so that when strong winds blow, since a large amount of dust is carried in the strong winds and the photovoltaic panel 4 is in a horizontal state, the problem of a large amount of dust falling onto the surface of the photovoltaic panel 4 can be prevented.

[0038] Furthermore, in the process that the pushing plate 122 pushes the mounting plate 3, the buffer pad 12201 is used to buffer between the mounting plate 3 and the pushing plate 122, so as to better protect the photovoltaic panel 4 and reduce damage.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1-Figure 3 and Figure 6As shown, it also includes a slip ring 221, a connecting plate 211, a spring telescopic rod 212 and a rubber squeezing ball 213; each rotating shaft rod 2 is connected to a slip ring 221; each slip ring 221 is rotatably connected to two connecting plates 211 through a torsion spring, and the torsion spring at the connection between the slip ring 221 and the connecting plate 211 is in a compressed state; each connecting plate 211 is fixedly connected to a spring telescopic rod 212; the telescopic part of each spring telescopic rod 212 is fixedly connected to a rubber squeezing ball 213 for increasing the stability of the arc support plate 6, and each rubber squeezing ball 213 is in contact with the corresponding arc support plate 6.

[0041] It also includes two electric push rods 222; the shaft rod 2 is slidably connected to the corresponding slip ring 221, each shaft rod 2 is bolted to two electric push rods 222, and the telescopic part of each electric push rod 222 is bolted to the corresponding slip ring 221.

[0042] Considering that, in the process that the output shaft of the motor 113 pushes the mounting plate 3 and the parts connected thereto to rotate through the driving gear 112, the arc rack 111, the arc sliding plate 5, the arc spring member 7 and the arc support plate 6 in sequence, since the arc support plate 6 and the rotating shaft rod 2 are coaxially arranged, and the arc support plate 6 is supported by the arc spring member 7, although the arc support plate 6 cannot move a large range in the arc sliding plate 5, it is still easy to move a small range. Then, when the photovoltaic panel 4 is blown by a breeze, the mounting plate 3 and the parts connected thereto are easy to swing a small range with the connection between the rotating shaft rod 2 and the base frame 1 as the axis, making it difficult for the photovoltaic panel 4 to be stably aligned with the sunlight.

[0043] Therefore, a connecting plate 211, a spring telescopic rod 212 and a rubber squeezing ball 213 are additionally provided. The telescopic portion of the spring telescopic rod 212 is initially in a compressed state. The spring telescopic rod 212 presses the rubber squeezing ball 213 against the arc support plate 6, so that friction is generated between the arc support plate 6 and the rubber squeezing ball 213, so as to increase the stability of the arc support plate 6 in the arc slide plate 5, so that when the photovoltaic panel 4 is blown by a breeze, the mounting plate 3 and the parts connected thereto cannot swing in a small range around the connection between the rotating shaft rod 2 and the base frame 1, so as to prevent the problem that the photovoltaic panel 4 is difficult to be stably aligned with the sunlight.

[0044] It should be noted that, when the push plate 122 pushes the mounting plate 3 and the parts connected thereto to rotate, the friction between the arc-shaped support plate 6 and the rubber extrusion ball 213 does not affect the movement of the arc-shaped support plate 6 in the arc-shaped sliding board 5 .

[0045] It should be noted that when the curved sliding board 5 rotates, the curved sliding board 5 pushes the connecting plate 211 in the rotating direction to rotate, while the connecting plate 211 not located in the rotating direction of the curved sliding board 5 is kept in contact with the curved sliding board 5 by the torsion spring.

[0046] It is taken into consideration that, in the process of the arc spring member 7 pushing the mounting plate 3 and the parts connected thereto to restore to the inclined state before the strong wind, the arc spring member 7 is affected by the friction between the arc support plate 6 and the rubber squeeze ball 213, and the mounting plate 3 and the parts connected thereto are restored to a deviation in the inclined angle, which results in a deviation between the photovoltaic panel 4 and the sunlight when the mounting plate 3 and the parts connected thereto are restored to the inclined state.

[0047] Therefore, a slip ring 221 and an electric push rod 222 are additionally provided. When the push plate 122 moves away from the mounting plate 3, the telescopic portion of the electric push rod 222 is controlled to move the rubber squeezing ball 213 away from the arc support plate 6 through the slip ring 221, the connecting plate 211 and the spring telescopic rod 212 in sequence, so that the friction force between the arc support plate 6 and the rubber squeezing ball 213 disappears, thereby preventing the arc spring member 7 from being affected by the friction force between the arc support plate 6 and the rubber squeezing ball 213, causing the mounting plate 3 and its connected parts to have a deviation in the tilt angle restored.

[0048] When the mounting plate 3 and the parts connected thereto are restored to the inclined state before the strong wind, the telescopic portion of the electric push rod 222 is controlled to make the rubber squeezing ball 213 contact the arc support plate 6 again through the slip ring 221, the connecting plate 211 and the spring telescopic rod 212 in sequence, so as to continue to increase the stability of the arc support plate 6 in the arc slide board 5.

[0049] Example 3

[0050] On the basis of Example 2, Figure 1 and Figure 4-Figure 5 As shown, it also includes a cleaning component; the mounting plate 3 is connected to two cleaning components distributed front and back; the cleaning component consists of a water storage frame 311 and a filter net 312; the mounting plate 3 is fixedly connected to a water storage frame 311 for storing water; the water storage frame 311 is connected to a filter net 312 for filtering impurities.

[0051] The water storage frame 311 is rotatably connected to the rotating plate 313 , and the rotating plate 313 is fixedly connected to the filter screen 312 , and the water storage frame 311 and the filter screen 312 are connected together through the rotating plate 313 .

[0052] It also includes a sliding plate 314 and a counterweight ball 315 ; the water storage frame 311 is slidably connected to the sliding plate 314 ; and the sliding plate 314 is fixedly connected to three counterweight balls 315 .

[0053] Considering that the photovoltaic panel 4 is exposed to the air for a long time, dust will adhere to the surface of the photovoltaic panel 4. If it is not cleaned, it will also affect the normal power generation of the photovoltaic panel 4.

[0054] Therefore, a cleaning component is added. On rainy days, when the mounting plate 3 is in an inclined state with the left side facing downward and the right side facing upward, rainwater falling onto the photovoltaic panel 4 will flow through the left filter screen 312. After being filtered by the left filter screen 312, the rainwater will flow to the left water storage frame 311 for storage. Conversely, rainwater will also be stored in the right water storage frame 311, so that the present invention can collect rainwater when it rains. In the process of the arc spring member 7 pushing the mounting plate 3 and its connected parts to restore to the inclined state before the strong wind through the corresponding arc support plate 6, the rainwater in the water storage frame 311 on the side of the mounting plate 3 tilted upward will be sprinkled onto the photovoltaic panel 4 under the action of inertia to wash away the dust on the surface of the photovoltaic panel 4, so as to prevent the photovoltaic panel 4 from being exposed to the air for a long time, and the surface of the photovoltaic panel 4 will be attached to dust. If it is not cleaned, it will affect the normal power generation of the photovoltaic panel 4.

[0055] Taking into account that, in the process that rainwater in the water storage frame 311 will be sprinkled onto the photovoltaic panel 4 under the action of inertia, the rainwater will be difficult to be sprinkled onto the photovoltaic panel 4 under the action of the filter net 312; therefore, a rotating plate 313 is added, and the water storage frame 311 and the filter net 312 are connected together through the rotating plate 313, and the rotating plate 313 cannot rotate toward the inside of the water storage frame 311, so that when the rainwater in the water storage frame 311 is sprinkled out under the action of inertia, the rotating plate 313 will rotate away from the water storage frame 311 under the action of inertia, and drive the filter net 312 away from the water storage frame 311, so that the filter net 312 will not block the rainwater from being sprinkled out of the water storage frame 311, so as to prevent the problem that the rainwater will be difficult to be sprinkled onto the photovoltaic panel 4 under the action of the filter net 312.

[0056] Furthermore, by adding a sliding plate 314 and a counterweight ball 315, the counterweight ball 315 pushes the sliding plate 314 to move toward the frame opening of the water storage frame 311 under the action of inertia, so that the sliding plate 314 pushes the rainwater in the water storage frame 311 to move, so that the rainwater in the water storage frame 311 can be better sprinkled onto the photovoltaic panel 4.

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
