[0025] like Figure 3 、 Figure 6 and Figure 9As shown, it also includes an unlocking mechanism, which includes a first elastic telescopic rod 601, a first elastic telescopic rod 601 and a second elastic telescopic rod 602 fixedly connected in the detection box 203, the top of the first elastic telescopic rod 601 is connected to one end of a first hose, the other end of the first hose passes through the detection box 203 and is connected to the first air guide box 204, the top of the second elastic telescopic rod 602 is connected to one end of a second hose, the other end of the second hose passes through the detection box 203 and is connected to the second air guide box 206, the T-shaped frame 301 is used in conjunction with the telescopic ends of the first elastic telescopic rod 601 and the second elastic telescopic rod 602 respectively, and when the T-shaped frame 301 moves, It can allow the air in the inner cavity of the first elastic telescopic rod 601 to enter the first air guide box 204, or the air in the inner cavity of the second elastic telescopic rod 602 to enter the second air guide box 206.

[0026] like Figure 6 、 Figure 8 and Figure 10 The unlocking mechanism also includes a second extension rod 701, and the second extension rod 701 is fixedly connected to the second mounting frame 503. A second air supply pipe is connected between the fixed end of the second extension rod 701 and the second through hole of the first air guide box 204 and the fourth through hole of the second air guide box 206. The telescopic end of the second extension rod 701 is fixedly connected to the second Z-shaped rod 702, and the top of the second extrusion rod 504 is fixedly connected to a second stop block used in conjunction with the second Z-shaped rod 702. When the telescopic end of the second extension rod 701 is extended, the second extrusion rod 504 can move.

[0027] like Figure 9 As shown, it also includes a sliding rod 801, and the sliding rod 801 is slidably connected to the first mounting frame 403 and the second mounting frame 503. A tension spring is provided between the sliding rod 801 and the first mounting frame 403 and the second mounting frame 503. A pin 802 is fixed to one side of the sliding rod 801, and the outer walls of the first extrusion rod 404 and the second extrusion rod 504 are provided with a slot for cooperating with the pin 802. When the pin 802 is inserted into the slot of the first extrusion rod 404 or the second extrusion rod 504, the first extrusion rod 404 or the second extrusion rod 504 can be limited.

[0028] like Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, a detection block 901 is also included. The detection block 901 is horizontally slidably connected in the first mounting frame 403 and the second mounting frame 503. A fifth compression spring is provided between the detection block 901 and the first mounting frame 403 and the second mounting frame 503. A sliding shaft is fixedly connected to the rectangular frame 202, and the sliding shaft is used in conjunction with the detection block 901. An extrusion block 1001 is fixedly connected to one side of the detection block 901, and a convex shaft used in conjunction with the extrusion block 1001 is fixedly connected to the bottom end of the sliding rod 801.

[0029] like Figure 7 As shown, it also includes an elastic wire box 1101. The top of the frame 201 is symmetrically rotated and connected to the elastic wire box 1101. The steel wire rope in the elastic wire box 1101 is fixedly connected to the sliding shaft of the rectangular frame 202. The steel wire rope of the elastic wire box 1101 can provide tension to the sliding shaft of the rectangular frame 202.

[0030] Initially, the first limiting axis 401 and the second limiting axis 501 are both inserted into the first axis hole and the second axis hole of the corresponding rectangular frame 202, and the rectangular frame 202 is parallel to the corresponding frame 201. The first air guide frame 205 is located between the first through hole and the second through hole of the first air guide box 204, and the second air guide frame 207 is located between the fourth through hole and the third through hole of the second air guide box 206. The adjustment frame 1 makes the photovoltaic panel face the direction of the rising sun through the three frames 201 and the three rectangular frames 202. Taking one of the frames 201 as an example, when strong wind occurs, it is divided into four states according to the wind direction of the strong wind. The first state is that the strong wind blows toward the right rear. At this time, the detection box 203 is hit by the strong wind and rotates clockwise with the connection point of the frame 201 as the center of the circle, and the damping ring is aligned with the detection The detection box 203 applies friction to make the detection box 203 rotate slowly. It is worth noting that at this time, the front sides of the two detection plates 302 are not facing the strong wind, and the impact force of the strong wind on the two detection plates 302 is relatively weak. In addition, due to the small size of the two detection plates 302, the two detection plates 302 will not affect the rotation of the detection box 203 when they are impacted. The telescopic end of the first elastic telescopic rod 601 can provide support for the T-shaped frame 301, and the T-shaped frame 301 will not move. When the detection box 203 rotates, the two guide grooves thereon squeeze the protruding shafts of the first air guide frame 205 and the second air guide frame 207 respectively. The protruding shaft of the first air guide frame 205 is forced to drive the first air guide frame 205 to slide to the right, and the protruding shaft of the second air guide frame 207 is forced to drive the second air guide frame 207 slides to the left, and at the same time, the detection box 203 drives the two detection plates 302 to move through the T-shaped frame 301 until the front sides of the two detection plates 302 are facing the strong wind. At this time, the detection box 203 no longer rotates under the action of the strong wind, and the second through hole of the first air guide box 204 is connected to the first hose through the first air guide frame 205, and the third through hole of the second air guide box 206 is connected to the second hose through the second air guide frame 207. The impact force of the strong wind on the two detection plates 302 increases, and the two detection plates 302 are driven by the strong wind to slide the T-shaped frame 301 along the detection box 203 to the right rear side, and the T-shaped frame 301 squeezes the telescopic end of the first elastic telescopic rod 601. The air in the inner cavity of the first elastic telescopic rod 601 is squeezed and passes through the first hose and the first air guide box 20 4 and the second air delivery pipe enter the inner cavity of the second extension rod 701, the telescopic end of the second extension rod 701 extends and drives the second Z-shaped rod 702 to move, the second Z-shaped rod 702 squeezes the second stopper of the second extrusion rod 504, and the second stopper is forced to drive the second extrusion rod 504 to slide leftward along the second mounting frame 503, the fourth compression spring is forced to contract, and the second extrusion rod 504 drives the fourth wedge block 505 to move leftward through the second support rod, and the two third compression springs are gradually released as the second extrusion rod 504 and the fourth wedge block 505 move, driving the third wedge block 502 to move, the two third wedge blocks 502 move away from each other, and drive the second limiting shaft 501 to move, and the second limiting shaft 501 moves out of the second shaft hole of the rectangular frame 202.After the rectangular frame 202 is free from restriction, it can move. At this time, the rectangular frame 202 is impacted by strong wind and rotates counterclockwise with the connection between the two first limit shafts 401 and the two first axis holes as the center. The two sliding shafts of the rectangular frame 202 pull out the steel wire ropes in the two elastic wire boxes 1101. After the sliding shafts slide, they no longer contact the corresponding detection blocks 901. After the detection blocks 901 are free from restriction, the fifth compression spring is released to drive the two detection blocks 901 to slide away from each other. The detection block 901 drives the extrusion block 1001 to slide. After the extrusion block 1001 slides, it no longer contacts the convex shaft of the adjacent sliding rod 801. The outer walls of the first extrusion rod 404 and the second extrusion rod 504 respectively contact the corresponding ends of the latch 802, and the two latches 802 cannot Movement, the strong wind continues to impact the two detection plates 302, causing the second extrusion rod 504 to continue sliding to the left, so that the slot of the second extrusion rod 504 is aligned with the latch 802 on the right side. The tension spring contracts and drives the sliding rod 801 to slide. The sliding rod 801 drives the latch 802 to insert into the slot of the second extrusion rod 504, thereby limiting the second extrusion rod 504. The second extrusion rod 504 limits the fourth wedge block 505 through the second support rod. At this time, a gap is generated between the right side of the rectangular frame 202 and the frame 201. The strong wind can pass through the gap between the rectangular frame 202 and the frame 201, thereby reducing the impact force of the strong wind on the rectangular frame 202 and the frame 201, and preventing the rectangular frame 202 and the frame 201 from being damaged.

[0031] When the strong wind disappears, the strong wind no longer impacts the rectangular frame 202, the detection box 203 and the detection plate 302. The damping ring applies friction to the detection box 203. Under the action of the damping ring, the detection box 203 will not rotate around the connection point of the frame 201. The two detection plates 302 no longer drive the T-shaped frame 301 to squeeze the first elastic telescopic rod 601. The telescopic end of the first elastic telescopic rod 601 is released and extended, and the air in the inner cavity of the second extension rod 701 is pumped back to the inner cavity of the first elastic telescopic rod 601 through the first hose, the first air guide box 204 and the second air supply pipe. The telescopic end of the extension rod 701 contracts and resets, and drives the second Z-shaped rod 702 to move and reset. After the second Z-shaped rod 702 is reset, it no longer contacts the second stopper of the second extrusion rod 504. At the same time, the steel wire ropes of the two elastic wire boxes 1101 contract and apply tension to the two sliding shafts of the rectangular frame 202. The two sliding shafts are driven by the force to drive the rectangular frame 202 to rotate clockwise with the connection between the two first limit shafts 401 and the two first shaft holes as the center of the circle. Then, the two sliding shafts contact and squeeze the inclined surfaces of the two detection blocks 901 respectively, so that the two detection blocks 901 drive the extrusion blocks 1001 thereon. When the two extrusion rods 504 are moved closer to each other, the fifth compression spring is forced to shrink. When the extrusion block 1001 on the right side moves, the inclined surface of the extrusion block 1001 contacts and squeezes the convex shaft of the adjacent sliding rod 801. The convex shaft is forced to drive the sliding rod 801 to slide and reset. The tension spring is forced to extend, and the sliding rod 801 drives the latch 802 to move and reset. After the latch 802 is reset, it disengages from the slot of the second extrusion rod 504. The second extrusion rod 504 can move after being freed from the restriction. At the same time, the two second axis holes of the rectangular frame 202 are aligned with the two second limit shafts 501. The fourth compression spring is released to drive the second extrusion rod 504 to move Sliding to the right, the second extrusion rod 504 drives the fourth wedge block 505 to move to the right through the second support rod, and then the second extrusion rod 504 and the fourth wedge block 505 respectively contact and squeeze the inclined surfaces of the two third wedge blocks 502. The two third wedge blocks 502 are forced to move closer to each other and drive the second limiting shaft 501 to move. The third compression spring is forced to shrink. After movement, the two second limiting shafts 501 are respectively inserted into the two second shaft holes, thereby limiting the rectangular frame 202 and keeping the rectangular frame 202 parallel to the frame 201, thereby completing the rotation and reset of the rectangular frame 202.

[0032] The second state is that strong wind blows toward the left rear. At this time, the detection box 203 is blown by the strong wind and rotates counterclockwise with the connection point of the frame 201 as the center. The damping ring applies friction to the detection box 203, causing the detection box 203 to rotate slowly. When the detection box 203 rotates, the two guide grooves thereon squeeze the protruding shafts of the first air guide frame 205 and the second air guide frame 207. The protruding shaft of the first air guide frame 205 is forced to drive the first air guide frame 205 to slide to the left, and the protruding shaft of the second air guide frame 207 is forced to drive the second air guide frame 207 to slide to the right. At the same time, the detection box 203 drives the two adjacent detection plates 302 to move through the T-shaped frame 301 until the front sides of the two detection plates 302 are facing the strong wind. At this time, the detection box 203 no longer rotates under the action of the strong wind. The first through hole of the first air guide box 204 is connected to the first hose through the first air guide frame 205, and the fourth through hole of the second air guide box 206 is connected to the second hose through the second air guide frame 207. The strong wind increases the impact force of the two detection plates 302. The two detection plates 302 are impacted by the strong wind and drive the T-shaped frame 301 to slide to the left rear side along the detection box 203. The T-shaped frame 301 squeezes the telescopic end of the first elastic telescopic rod 601. The air in the inner cavity of the first elastic telescopic rod 601 is squeezed and enters the inner cavity of the first extension rod 603 through the first hose, the first air guide box 204 and the first air supply pipe. The telescopic end of the first extension rod 603 extends and drives the first Z-shaped rod 604 to move. The first Z-shaped rod 604 hits the first stopper of the first extrusion rod 404 After the first wedge block 402 is pushed away from the first support frame 202, the first wedge block 402 is pushed away from the first support frame 202, and the first wedge block 402 is pushed away from the first support frame 202. After the first and second extrusion rods 404 and 504 are in contact with the ends of the corresponding latches 802, the two latches 802 cannot move. The strong wind keeps impacting the two detection plates 302, causing the first extrusion rod 404 to continue to slide to the right, so that the slot of the first extrusion rod 404 is aligned with the latch 802 on the left, and the contraction of the tension spring drives the sliding rod 801 to slide.Sliding rod 801 drives latch 802 into the slot of first extrusion rod 404, thereby restraining first extrusion rod 404. First extrusion rod 404 restrains second wedge block 405 via the first support rod. This creates a gap between the left side of rectangular frame 202 and frame 201, allowing strong winds to pass through the gap between rectangular frame 202 and frame 201. This reduces the impact of strong winds on rectangular frame 202 and frame 201, preventing damage to rectangular frame 202 and frame 201.

[0033] When the strong wind disappears, the strong wind no longer impacts the rectangular frame 202, the detection box 203 and the detection plate 302. The damping ring applies friction to the detection box 203. Under the action of the damping ring, the detection box 203 will not rotate around the connection point of the frame 201. The two detection plates 302 no longer drive the T-shaped frame 301 to squeeze the first elastic telescopic rod 601. The telescopic end of the first elastic telescopic rod 601 is released and extended, and the air in the inner cavity of the first extension rod 603 is pumped back to the inner cavity of the first elastic telescopic rod 601 through the first hose, the first air guide box 204 and the first air supply pipe. , the telescopic end of the first extension rod 603 shrinks and resets, and drives the first Z-shaped rod 604 to move and reset. After the first Z-shaped rod 604 is reset, it no longer contacts the first stopper of the first extrusion rod 404. At the same time, the steel wire ropes of the two elastic wire boxes 1101 shrink and apply tension to the two sliding shafts of the rectangular frame 202. The two sliding shafts are driven by the force to drive the rectangular frame 202 to rotate counterclockwise with the connection between the two second limiting shafts 501 and the two second shaft holes as the center of the circle. Then, the two sliding shafts contact and squeeze the inclined surfaces of the two detection blocks 901 respectively, so that the two detection blocks 901 drive the extrusion The blocks 1001 move closer to each other, the fifth compression spring is forced to shrink, and when the extrusion block 1001 on the left moves, the inclined surface of the extrusion block 1001 contacts and squeezes the convex shaft of the adjacent sliding rod 801, and the convex shaft is forced to drive the sliding rod 801 to slide and reset, and the tension spring is forced to extend, and the sliding rod 801 drives the latch 802 to move and reset. After the latch 802 is reset, it disengages from the slot of the first extrusion rod 404. The first extrusion rod 404 can move after being freed from the restriction. At the same time, the two first axis holes of the rectangular frame 202 are aligned with the two first limit shafts 401, and the second compression spring is released to drive the second An extrusion rod 404 slides to the left, and the first extrusion rod 404 drives the second wedge block 405 to move to the left through the first support rod. Then the first extrusion rod 404 and the second wedge block 405 respectively contact and squeeze the inclined surfaces of the two first wedge blocks 402. The two first wedge blocks 402 are forced to move closer to each other and drive the first limiting shaft 401 to move. After movement, the two first limiting shafts 401 are respectively inserted into the two first shaft holes, thereby limiting the rectangular frame 202 and keeping the rectangular frame 202 parallel to the frame 201, thereby completing the rotation and reset of the rectangular frame 202.

[0034] The third state is when strong wind blows toward the right front. At this time, the detection box 203 is blown by the strong wind and rotates counterclockwise with the connection point of the frame 201 as the center, so that the first through hole of the first air guide box 204 is connected with the first hose through the first air guide frame 205, and the fourth through hole of the second air guide box 206 is connected with the second hose through the second air guide frame 207, until the rear sides of the two detection plates 302 are facing the strong wind. The two detection plates 302 are impacted by the strong wind and drive the T-shaped frame 301 to slide toward the right front along the detection box 203. The T-shaped frame 301 squeezes the telescopic end of the second elastic telescopic rod 602. The air in the inner cavity of the second elastic telescopic rod 602 is squeezed and enters the inner cavity of the second extension rod 701 through the second hose, the second air guide box 206 and the second air pipe. The telescopic end of the second extension rod 701 extends and drives the second Z-shaped rod 702 to move. Repeat the above steps to disengage the second limiting shaft 501 from the second axis hole of the rectangular frame 202. The rectangular frame 202 can move after being freed from the restriction. At this time, the rectangular frame 202 is impacted by the strong wind and rotates clockwise with the connection between the two first limiting shafts 401 and the two first axis holes as the center. The strong wind continues to impact the two detection plates 302, and then the sliding rod 801 drives the pin 802 to be inserted into the slot of the second extrusion rod 504, thereby limiting the second extrusion rod 504. The second extrusion rod 504 limits the fourth wedge block 505 through the second support rod. At this time, a gap is generated between the right side of the rectangular frame 202 and the frame 201. The strong wind can pass through the gap between the rectangular frame 202 and the frame 201, thereby reducing the impact force of the strong wind on the rectangular frame 202 and the frame 201, and preventing the rectangular frame 202 and the frame 201 from being damaged.

[0035] When the strong wind disappears, the strong wind no longer impacts the rectangular frame 202, the detection box 203 and the detection plate 302. The damping ring applies friction to the detection box 203. Under the action of the damping ring, the detection box 203 will not rotate with the connection point of the frame 201 as the center of the circle. The two detection plates 302 no longer drive the T-shaped frame 301 to squeeze the second elastic telescopic rod 602. The telescopic end of the second elastic telescopic rod 602 is released and extended, and the air in the inner cavity of the second extension rod 701 is drawn back to the inner cavity of the second elastic telescopic rod 602 through the second hose, the second air guide box 206 and the second air supply pipe. The telescopic end of the second extension rod 701 contracts and resets, and the above steps are repeated to insert the two second limiting shafts 501 into the two second shaft holes respectively, thereby limiting the rectangular frame 202 and keeping the rectangular frame 202 parallel to the frame 201.

[0036] The fourth state is that strong wind blows toward the left front. At this time, the detection box 203 is blown by the strong wind and rotates clockwise with the connection point of the frame 201 as the center, so that the second through hole of the first air guide box 204 is connected with the first hose through the first air guide frame 205, and the third through hole of the second air guide box 206 is connected with the second hose through the second air guide frame 207, until the back sides of the two detection plates 302 are facing the strong wind. The two detection plates 302 are impacted by the strong wind and drive the T-shaped frame 301 to slide toward the left front along the detection box 203. The T-shaped frame 301 squeezes the telescopic end of the second elastic telescopic rod 602. The air in the inner cavity of the second elastic telescopic rod 602 is squeezed and enters the inner cavity of the first extension rod 603 through the second hose, the second air guide box 206 and the first air pipe. 03's telescopic end extends and drives the first Z-shaped rod 604 to move, and repeats the above steps to disengage the first limiting shaft 401 from the first axis hole of the rectangular frame 202. The rectangular frame 202 can move after being freed from the restriction. At this time, the rectangular frame 202 is impacted by the strong wind and rotates counterclockwise with the connection between the two second limiting shafts 501 and the two second axis holes as the center. The strong wind continues to impact the two detection plates 302, thereby causing the sliding rod 801 to drive the pin 802 to insert into the slot of the first extrusion rod 404. At this time, a gap is generated between the left side of the rectangular frame 202 and the frame 201. The strong wind can pass through the gap between the rectangular frame 202 and the frame 201, thereby reducing the impact force of the strong wind on the rectangular frame 202 and the frame 201, and preventing the rectangular frame 202 and the frame 201 from being damaged.

[0037] When the strong wind disappears, the rectangular frame 202, the detection box 203 and the detection plate 302 collide, and the damping ring applies friction to the detection box 203. Under the action of the damping ring, the detection box 203 will not rotate around the connection point of the frame 201. The telescopic end of the second elastic telescopic rod 602 is released and extended, and the air in the inner cavity of the first extension rod 603 is drawn back to the inner cavity of the first elastic telescopic rod 601 through the second hose, the second air guide box 206 and the first air supply pipe. The telescopic end of the first extension rod 603 contracts and resets, and drives the first Z-shaped rod 604 to move and reset, and repeat the above steps to insert the two first limiting shafts 401 into the two first shaft holes respectively, thereby limiting the rectangular frame 202 and keeping the rectangular frame 202 parallel to the frame 201.

[0038] It is worth noting that as the sun moves, the adjustment frame 1 can drive the three frames 201 to rotate according to the position of the sun, so that the three frames 201 are always facing the sun. When it is afternoon, the detection box 203 will be located on the lower side of the frame 201. When strong wind hits the detection box 203, the above effect can still be achieved.

[0039] The rectangular frame 202 of the present invention can rotate in different directions under four strong wind directions, thereby greatly reducing the impact force of strong wind on the frame 201 and the rectangular frame 202, preventing the frame 201 and the rectangular frame 202 from shaking greatly or directly cracking due to the impact of strong wind, effectively improving the wind resistance of the photovoltaic panel bracket, and compared with the photovoltaic panel bracket in the prior art, which directly adjusts the photovoltaic panel bracket to a horizontal state when encountering strong winds, the rectangular frame 202 of the present invention has a smaller rotation angle, so that the photovoltaic panel can receive sunlight over a larger area and with higher efficiency.
