Description

Technical Field

[0001] This invention relates to the field of photovoltaic mounting technology, and in particular to a photovoltaic panel mounting bracket with an adjustable installation angle. Background Technology

[0002] The wind resistance of photovoltaic panel supports is one of the core elements in the design and installation of photovoltaic power generation systems, directly affecting the system's safety, stability, and economy.

[0003] Strong winds can exert tremendous impact on photovoltaic (PV) mounting systems. If the PV panel mounting system is not wind-resistant enough, it can cause the PV panels to shift and the system to deform, or even cause the panels to fall off and the system to overturn, potentially causing secondary damage to surrounding buildings and people. In current technology, when facing strong winds, PV mounting systems are usually rotated to a horizontal position. While this can greatly reduce the impact of strong winds on the PV mounting system and prevent damage, it also leads to a significant decrease in the efficiency of the PV mounting system in receiving sunlight.

[0015] 1. Through the design of the detection mechanism, this invention enables the detection box to rotate around the connection point of the frame according to the wind direction when strong winds impact it. This causes the first air guide frame to move. Based on the detection results, the detection mechanism can move the locking mechanism, thereby creating a gap between the rectangular frame and the frame. This allows strong winds to pass through the gap between the rectangular frame and the frame, preventing the frame and rectangular frame from shaking significantly or breaking directly due to strong wind impacts. This effectively improves the wind resistance of the photovoltaic panel support.

[0016] 2. Through the design of the first and second limiting shafts, this invention enables the first or second limiting shaft to disengage from the first or second shaft hole of the rectangular frame when strong winds impact the detection plate. This allows the rectangular frame to rotate around the connection point between the first and first limiting shafts or the second shaft hole. By rotating the rectangular frame in different directions, the impact force of strong winds on the rectangular frame and the frame can be further reduced. Attached Figure Description

[0028] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0029] An adjustable photovoltaic panel mounting bracket, such as Figures 1-4As shown, the device includes an adjusting frame 1 and a detection mechanism. The detection mechanism is located on the upper side of the adjusting frame 1 and is used to detect the wind direction of strong winds. The detection mechanism includes a frame 201. Three evenly distributed frames 201 are located on the upper side of the adjusting frame 1 and are fixedly connected to each other. Two frames 201 on the left and right sides are respectively connected to the adjusting frame 1. The adjusting frame 1 can rotate the three frames 201 according to the position of the sun, ensuring that the three frames 201 always face the sun (the adjusting frame 1 is existing technology and will not be described further here). Each of the three frames 201 contains a rectangular... A rectangular frame 202 is provided, on which photovoltaic panels can be installed. Each of the three frames 201 is equipped with a locking mechanism for locking the rectangular frame 202. A detection box 203 is hinged to the top of each of the three frames 201 and a damping ring is fixed thereon. The top of the damping ring is in contact with the bottom of the detection box 203.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the detection mechanism also includes a second air guide box 206. The upper side of each of the three frames 201 is provided with a second air guide box 206. The second air guide box 206 is located in front of the first air guide box 204.

The bottom of the first air guide frame 205 and the second air guide frame 207 are both fixed with protruding shafts. One end of the protruding shaft is inserted into the guide groove and slides inside it. The top of the second air guide box 206 is provided with a third through hole and a fourth through hole. The fourth through hole is located to the right of the third through hole.

[0031] like Figure 3 As shown, the testing mechanism also includes a T-shaped frame 301. The T-shaped frame 301 is slidably connected inside the testing box 203. Testing plates 302 are symmetrically fixed to both sides of the T-shaped frame 301. When a strong wind impacts the testing plates 302, the T-shaped frame 301 can slide along the testing box 203.

[0032] like Figure 6 and Figure 7As shown, the locking mechanism includes a first limiting shaft 401. The first limiting shaft 401 is symmetrically and slidably connected to each of the three frames 201. Two of the first limiting shafts 401 are located on the top left and bottom left of the frames 201, respectively. A first wedge block 402 is fixed to the ends of the two first limiting shafts 401 that are far apart from each other. A first compression spring is provided between the first wedge block 402 and the frame 201. The first compression spring is sleeved on the outer wall of the first limiting shaft 401. Symmetrical openings are provided on the rectangular frame 202 to connect with the first limiting shaft 401. The first shaft hole is used in conjunction with the shaft 401. The two first shaft holes are respectively set to correspond to the two first limiting shafts 401. The top of each of the three frames 201 is fixedly connected to a first mounting bracket 403. The first mounting bracket 403 is horizontally slidably connected to a first extrusion rod 404 that works with the first wedge block 402. A second compression spring is provided between the first extrusion rod 404 and the first mounting bracket 403. The front side of the first extrusion rod 404 is fixedly connected to a second wedge block 405 that works with the first wedge block 402 through a first support rod.

[0033] like Figure 6 and Figure 8 As shown, the locking mechanism also includes a second limiting shaft 501. The three frames 201 are symmetrically connected with the second limiting shaft 501 in a through-sliding manner. Two of the second limiting shafts 501 are located on the top right and bottom right sides of the frame 201, respectively. A third wedge block 502 is fixed to the ends of the two second limiting shafts 501 that are far apart from each other. A third compression spring is provided between the third wedge block 502 and the frame 201. The third compression spring is sleeved on the outer wall of the second limiting shaft 501. The rectangular frame 202 has symmetrically opened second limiting shafts 501 for use with the second limiting shafts 501. The shaft hole and the two second shaft holes are respectively set to correspond to the two second limit shafts 501. The top of the three frames 201 are all fixedly connected to the second mounting bracket 503. The second mounting bracket 503 is located on the right side of the first mounting bracket 403. The second mounting bracket 503 is horizontally slidably connected to the second pressing rod 504 that cooperates with the third wedge block 502. A fourth compression spring is set between the second pressing rod 504 and the second mounting bracket 503. The front side of the second pressing rod 504 is fixedly connected to the fourth wedge block 505 that cooperates with the third wedge block 502 through the second support rod.

[0034] like Figure 3 , Figure 6 and Figure 9As shown, it also includes an unlocking mechanism, which includes a first elastic telescopic rod 601. The first elastic telescopic rod 601 and a second elastic telescopic rod 602 are fixedly connected inside the detection box 203. The top of the first elastic telescopic rod 601 is connected to one end of a first flexible hose, and the other end of the first flexible hose passes through the detection box 203 and connects to a first air guide box 204. The top of the second elastic telescopic rod 602 is connected to one end of a second flexible hose, and the other end of the second flexible hose passes through the detection box 203 and connects to a second air guide box 206. A 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. When the T-shaped frame 301 moves... The first elastic telescopic rod 601 allows air to enter the first air guide box 204, or the second elastic telescopic rod 602 allows air to enter the second air guide box 206. A first extension rod 603 is fixedly connected to the first mounting bracket 403. A first air supply pipe is connected between the fixed end of the first extension rod 603 and the first through hole of the first air guide box 204 and the third through hole of the second air guide box 206. A first Z-shaped rod 604 is fixedly connected to the telescopic end of the first extension rod 603. A first stop block that cooperates with the first Z-shaped rod 604 is fixedly connected to the top of the first extrusion rod 404. When the telescopic end of the first extension rod 603 extends, the first extrusion rod 404 can move.

[0035] like Figure 6 , Figure 8 and Figure 10 The unlocking mechanism further includes a second extension rod 701. The second extension rod 701 is fixedly connected to the second mounting bracket 503. The fixed end of the second extension rod 701 is connected to the second through hole of the first air guide box 204 and the fourth through hole of the second air guide box 206 through a second air supply pipe. The telescopic end of the second extension rod 701 is fixedly connected to a second Z-shaped rod 702. The top of the second compression rod 504 is fixedly connected to a second stop block that cooperates with the second Z-shaped rod 702. When the telescopic end of the second extension rod 701 extends, it can make the second compression rod 504 move.

[0036] like Figure 9 As shown, it also includes a sliding rod 801. The sliding rod 801 is slidably connected in both the first mounting bracket 403 and the second mounting bracket 503. A tension spring is provided between the sliding rod 801 and the first mounting bracket 403 and the second mounting bracket 503. A pin 802 is fixedly connected to one side of the sliding rod 801. The outer walls of the first pressing rod 404 and the second pressing rod 504 are provided with slots that cooperate with the pin 802. When the pin 802 is inserted into the slot of the first pressing rod 404 or the second pressing rod 504, it can limit the first pressing rod 404 or the second pressing rod 504.

[0037] like Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, it also includes a detection block 901. The detection block 901 is horizontally slidably connected in both the first mounting bracket 403 and the second mounting bracket 503. A fifth compression spring is provided between the detection block 901 and the first mounting bracket 403 and the second mounting bracket 503. A sliding shaft is fixedly connected to the rectangular frame 202. The sliding shaft is used in conjunction with the detection block 901. A pressing block 1001 is fixedly connected to one side of the detection block 901. A convex shaft that works in conjunction with the pressing block 1001 is fixedly connected to the bottom end of the sliding rod 801.

[0038] like Figure 7 As shown, it also includes a flexible wire box 1101. The top of the frame 201 is symmetrically and rotatably connected to the flexible wire box 1101. The steel wire rope inside the flexible wire box 1101 is fixedly connected to the sliding shaft of the rectangular frame 202. The steel wire rope of the flexible wire box 1101 can provide tension to the sliding shaft of the rectangular frame 202.

[0039] Initially, the first limiting shaft 401 and the second limiting shaft 501 are both engaged in the first and second shaft holes of the corresponding rectangular frame 202. The rectangular frame 202 and the corresponding frame 201 are parallel. The first air guide frame 205 is located between the first and second through holes of the first air guide box 204, and the second air guide frame 207 is located between the fourth and third through holes of the second air guide box 206. The adjusting frame 1 uses the three frames 201 and the three rectangular frames 202 to orient the photovoltaic panel toward the direction of the rising sun. Taking one of the frames 201 as an example, when a strong wind occurs, there are four states depending on the wind direction. The first state is when the strong wind blows to the right and rear. At this time, the detection box 203 is impacted by the strong wind and rotates clockwise around the connection of the frame 201. The damping ring detects the... Friction is applied to the test box 203, causing it to rotate slowly. It is worth noting that at this time, the front sides of the two test plates 302 are not directly facing the strong wind, so the impact of the strong wind on the two test plates 302 is weak. Furthermore, due to the small size of the two test plates 302, the impact will not affect the rotation of the test box 203. The telescopic end of the first elastic telescopic rod 601 provides support for the T-shaped frame 301, preventing it from moving. When the test box 203 rotates, it presses against the protruding shafts of the first air guide frame 205 and the second air guide frame 207 respectively through its two guide grooves. The protruding shaft of the first air guide frame 205 is forced to slide to the right, and the protruding shaft of the second air guide frame 207 is forced to slide to the right. 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 of the two detection plates 302 is directly facing the strong wind. At this time, the detection box 203 stops rotating under the action of the strong wind. 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. 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. 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 207. 4. The second air supply pipe enters 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 compresses the second stop of the second extrusion rod 504. The second stop, under force, drives the second extrusion rod 504 to slide to the left along the second mounting bracket 503. The fourth compression spring contracts under force. The second extrusion rod 504 drives the fourth wedge block 505 to move to the left through the second support rod. The two third compression springs gradually release with the movement of the second extrusion rod 504 and the fourth wedge block 505, 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. After the second limiting shaft 501 moves, it disengages from the second shaft hole of the rectangular frame 202.After the rectangular frame 202 is released from its restraints, it can move. At this time, the rectangular frame 202 is impacted by strong winds and rotates counterclockwise around the connection points of the two first limiting shafts 401 and the two first shaft holes. 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 released from their restraints, the fifth compression spring releases, causing the two detection blocks 901 to slide away from each other. The detection blocks 901 drive the pressing block 1001 to slide. After the pressing block 1001 slides, it no longer contacts the convex shaft of the adjacent sliding rod 801. The outer walls of the first pressing rod 404 and the second pressing rod 504 respectively contact the ends of the corresponding pins 802, and the two pins 802 cannot... The strong wind continues to impact the two detection plates 302, causing the second compression rod 504 to slide further to the left. This aligns the slot of the second compression rod 504 with the right-side pin 802. The tension spring contracts, causing the sliding rod 801 to slide. The sliding rod 801 then drives the pin 802 into the slot of the second compression rod 504, thus limiting the second compression rod 504. The second compression rod 504, through the second support rod, limits the fourth wedge block 505. At this point, a gap is created between the right side of the rectangular frame 202 and the frame 201. The strong wind can pass through this gap, reducing the impact force on the rectangular frame 202 and frame 201 and preventing damage to them.

[0040] When the strong wind dissipates, it 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, preventing it from rotating around the connection point of the frame 201 under the action of the damping ring. The two detection plates 302 no longer cause the T-shaped frame 301 to press against the first elastic telescopic rod 601. The telescopic end of the first elastic telescopic rod 601 extends and draws air from the inner cavity of the second extension rod 701 back into 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 retracts and resets, driving the second Z-shaped rod 702 to move and reset. After resetting, the second Z-shaped rod 702 no longer contacts the second stop of the second pressing rod 504. At the same time, the wire ropes of the two elastic wire boxes 1101 retract and apply tension to the two sliding shafts of the rectangular frame 202. The two sliding shafts, under the force, drive the rectangular frame 202 to rotate clockwise around the connection between the two first limiting shafts 401 and the two first shaft holes. Subsequently, the two sliding shafts contact and press the inclined surfaces of the two detection blocks 901 respectively, causing the two detection blocks 901 to drive the pressing blocks 1001 on them. As the two parts move closer together, the fifth compression spring contracts under pressure. When the right-side pressing block 1001 moves, its inclined surface contacts and presses against the convex shaft of the adjacent sliding rod 801. The convex shaft is forced to push the sliding rod 801 back to its original position. The tension spring extends under pressure, and the sliding rod 801 pushes the pin 802 back to its original position. After the pin 802 returns to its original position, it disengages from the slot of the second pressing rod 504. The second pressing rod 504 is then freed from its restraints and can move. At the same time, the two second shaft holes of the rectangular frame 202 align with the two second limiting shafts 501. The fourth compression spring releases, causing the second pressing rod 504 to move towards... Sliding to the right, the second pressing rod 504 drives the fourth wedge block 505 to move to the right via the second support rod. Subsequently, the second pressing rod 504 and the fourth wedge block 505 respectively contact and press the inclined surfaces of the two third wedge blocks 502. The two third wedge blocks 502 move closer to each other under force, and drive the second limiting shaft 501 to move. The third compression spring contracts under force. After the two second limiting shafts 501 move, they 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, thus completing the rotation and reset of the rectangular frame 202.

[0041] In the second state, a strong wind blows to the left and rear. At this time, the detection box 203 is driven by the strong wind to rotate counterclockwise around the connection point of the frame 201. The damping ring applies friction to the detection box 203, causing it to rotate slowly. As the detection box 203 rotates, it presses against the protruding shafts of the first air guide frame 205 and the second air guide frame 207 through its two guide grooves. The protruding shaft of the first air guide frame 205 is forced to slide to the left, and the protruding shaft of the second air guide frame 207 is forced to slide to the right. Simultaneously, the detection box 203, through the T-shaped frame 301, drives the two adjacent detection plates 302 to move until the front of the two detection plates 302 faces the strong wind. At this point, the detection box 203 stops rotating under the influence 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 impact force of the strong wind on the two detection plates 302 increases. 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 left and rear. The T-shaped frame 301 squeezes the extension end of the first elastic telescopic rod 601. The air in the cavity of the first elastic telescopic rod 601 is squeezed and enters the cavity of the first extension rod 603 through the first hose, the first air guide box 204 and the first air supply pipe. The extension end of the first extension rod 603 extends and drives the first Z-shaped rod 604 to move. The first Z-shaped rod 604 stops the first block of the first compression rod 404. When compressed, the first stop block is forced to slide the first compression rod 404 to the right along the first mounting bracket 403. The second compression spring is compressed, and the first compression rod 404 drives the second wedge block 405 to move to the right through the first support rod. The two first compression springs are gradually released as the first compression rod 404 and the second wedge block 405 move, causing the first wedge block 402 to move. The two first wedge blocks 402 move away from each other and drive the first limiting shaft 401 to move. After the first limiting shaft 401 moves, it disengages from the first shaft hole of the rectangular frame 202. After the rectangular frame 202 is freed from the restriction, it can move. At this time, the rectangular frame 202 is impacted by strong wind and rotates clockwise around the connection between the two second limiting shafts 501 and the two second shaft holes. A sliding shaft pulls out the steel wire ropes from the two elastic wire boxes 1101. After sliding, the sliding shaft no longer contacts the corresponding detection block 901. After the detection block 901 is released from its restraint, the fifth compression spring releases, causing the two detection blocks 901 to slide away from each other. The detection block 901 drives the pressing block 1001 to slide. After the pressing block 1001 slides, it no longer contacts the convex shaft of the adjacent sliding rod 801. The outer walls of the first pressing rod 404 and the second pressing rod 504 respectively contact the ends of the corresponding pins 802. The two pins 802 cannot move. The strong wind continues to impact the two detection plates 302, causing the first pressing rod 404 to continue sliding to the right, aligning the slot of the first pressing rod 404 with the left pin 802. The tension spring contracts, causing the sliding rod 801 to slide.The sliding rod 801 drives the pin 802 to insert into the slot of the first pressing rod 404, thereby limiting the first pressing rod 404. The first pressing rod 404 limits the second wedge block 405 through the first support rod. At this time, a gap is created between the left side of the rectangular frame 202 and the frame 201. Strong winds can pass through the gap between the rectangular frame 202 and the frame 201, thereby reducing the impact force of strong winds on the rectangular frame 202 and the frame 201 and preventing damage to the rectangular frame 202 and the frame 201.

[0042] When the strong wind subsides, it 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, preventing it from rotating around the connection point of the frame 201. The two detection plates 302 no longer cause the T-shaped frame 301 to press against the first elastic telescopic rod 601. The telescopic end of the first elastic telescopic rod 601 extends and draws air back into the 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 retracts and resets, driving the first Z-shaped rod 604 to move and reset. After resetting, the first Z-shaped rod 604 no longer contacts the first stop of the first compression rod 404. At the same time, the wire ropes of the two elastic wire boxes 1101 retract and apply tension to the two sliding shafts of the rectangular frame 202. The two sliding shafts, under the force, drive the rectangular frame 202 to rotate counterclockwise around the connection between the two second limiting shafts 501 and the two second shaft holes. Subsequently, the two sliding shafts contact and compress the inclined surfaces of the two detection blocks 901 respectively, causing the two detection blocks 901 to drive the compression surfaces on them. As blocks 1001 move closer together, the fifth compression spring contracts under pressure. When the left-side pressing block 1001 moves, its inclined surface contacts and presses against the convex shaft of the adjacent sliding rod 801. The convex shaft is forced to push the sliding rod 801 back to its original position. The tension spring extends under pressure, and the sliding rod 801 pushes the pin 802 back to its original position. After the pin 802 returns to its original position, it disengages from the slot of the first pressing rod 404. The first pressing rod 404 is freed from its restraint and can move. At the same time, the two first shaft holes of the rectangular frame 202 align with the two first limiting shafts 401. The second compression spring releases, pushing the first... A compression rod 404 slides to the left, and the first compression rod 404 drives the second wedge block 405 to move to the left through the first support rod. Then, the first compression rod 404 and the second wedge block 405 respectively contact and compress the inclined surfaces of the two first wedge blocks 402. The two first wedge blocks 402 move closer to each other under force, and drive the first limiting shaft 401 to move. After the two first limiting shafts 401 move, they 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, thus completing the rotation and reset of the rectangular frame 202.

[0043] In the third state, a strong wind blows to the right and forward. At this time, the detection box 203 is driven by the strong wind to rotate counterclockwise around the connection point of the frame 201. This causes the first through-hole of the first air guide box 204 to connect to the first hose through the first air guide frame 205, and the fourth through-hole of the second air guide box 206 to connect to the second hose through the second air guide frame 207, until the rear sides of the two detection plates 302 are directly facing the strong wind. The impact of the strong wind causes the T-shaped frame 301 to slide along the detection box 203 to the right and forward. The T-shaped frame 301 compresses the telescopic end of the second elastic telescopic rod 602, compressing the air inside the second elastic telescopic rod 602 and allowing it to enter the inner cavity of the second extension rod 701 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 extends and drives the second Z-shaped rod 702 to move. The above steps are repeated to disengage the second limiting shaft 501 from the second shaft hole of the rectangular frame 202. After the rectangular frame 202 is freed from the restriction, it can move. At this time, the rectangular frame 202 is impacted by strong wind and rotates clockwise around the connection between the two first limiting shafts 401 and the two first shaft holes. 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 second pressing rod 504, thereby limiting the second pressing rod 504. The second pressing 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 damage to the rectangular frame 202 and the frame 201.

[0044] After the strong winds subside, they no longer impact the rectangular frame 202, the detection box 203, and the detection plate 302. The damping ring applies friction to the detection box 203, preventing it from rotating around the connection point of the frame 201. The two detection plates 302 no longer cause the T-shaped frame 301 to press against the second elastic telescopic rod 602. The telescopic end of the second elastic telescopic rod 602 extends and draws air from the inner cavity of the second extension rod 701 back into 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 retracts and resets, and the above steps are repeated to insert the two second limiting shafts 501 into the two second shaft holes, thereby limiting the rectangular frame 202 and keeping it parallel to the frame 201.

[0045] The fourth state is characterized by a strong wind blowing towards the left front. In this state, the detection box 203 is rotated clockwise around the connection point of the frame 201 due to the strong wind. This causes the second through hole of the first air guide box 204 to connect to the first hose through the first air guide frame 205, and the third through hole of the second air guide box 206 to connect to the second hose through the second air guide frame 207, until the rear sides of the two detection plates 302 are directly facing the strong wind. The impact of the strong wind causes the T-shaped frame 301 to slide along the detection box 203 towards the left front. The T-shaped frame 301 compresses the extension end of the second elastic telescopic rod 602, compressing the air inside the second elastic telescopic rod 602 and allowing it to enter the inner cavity of the first extension rod 603 through the second hose, the second air guide box 206, and the first air supply pipe. The telescopic end of 03 extends and drives the first Z-shaped rod 604 to move, and repeats the above steps to make the first limiting shaft 401 disengage from the first shaft hole of the rectangular frame 202. After the rectangular frame 202 is freed from the restriction, it can move. At this time, the rectangular frame 202 is impacted by strong wind and rotates counterclockwise around the connection between the two second limiting shafts 501 and the two second shaft holes. 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 pressing 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 damage to the rectangular frame 202 and the frame 201.

[0046] When the strong winds subside, the rectangular frame 202, the detection box 203, and the detection plate 302 impact each other. The damping ring applies friction to the detection box 203, preventing it from rotating around the connection point of the frame 201 under the action of the damping ring. The extension end of the second elastic telescopic rod 602 extends and draws the air from the inner cavity of the first extension rod 603 back into 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 extension end of the first extension rod 603 retracts and resets, driving the first Z-shaped rod 604 to move and reset. The above steps are repeated so that the two first limiting shafts 401 are inserted into the two first shaft holes respectively, thereby limiting the rectangular frame 202 and keeping it parallel to the frame 201.

[0047] It is worth noting that as the sun moves, the adjustment frame 1 can drive the three frames 201 to rotate according to the sun's position, so that the three frames 201 always face the sun. When it is afternoon, the detection box 203 will be located on the lower side of the frame 201. Even when strong winds hit the detection box 203, the above effect can still be achieved.

[0048] The rectangular frame 202 of the present invention can rotate in different directions under four strong wind conditions, thereby greatly reducing the impact of strong winds on the frame 201 and the rectangular frame 202, preventing the frame 201 and the rectangular frame 202 from shaking significantly or breaking directly due to strong wind impacts, effectively improving the wind resistance of the photovoltaic panel support. Moreover, compared with the photovoltaic panel support in the prior art, which directly adjusts the photovoltaic panel support to a horizontal state when encountering strong winds, the rectangular frame 202 of the present invention has a smaller rotation angle, thereby enabling the photovoltaic panel to receive sunlight with a larger area and higher efficiency.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
