Description

Technical Field

[0001] This invention relates to the field of solar panel support technology, specifically to a solar panel support sway warning device. Background Technology

[0002] Solar panel supports are an important component of solar power generation systems. Their function is to support the solar panels, enabling them to stably receive solar energy and convert it into electrical energy. Regular inspection and maintenance are necessary to ensure the proper functioning of the solar panel supports and extend their lifespan.

[0003] When using solar panel brackets, they often encounter windy weather. The wind blows onto the solar panels, and the force is transmitted to the solar panel brackets at the bottom of the solar panels. Under the long-term influence of wind, the solar panel brackets may sway.

[0004] Currently, most existing solar panel supports lack the function to reduce the force of wind on the solar panel supports when they sway, resulting in the solar panel supports being greatly affected by wind. At the same time, the solar panel supports do not have a supporting structure when they sway, which may lead to them falling over due to prolonged swaying, which is quite dangerous. Furthermore, when the solar panel supports sway, there is no warning function, which means that people cannot notice it in time, thus preventing the solar panels from being repaired in a timely manner and failing to meet people's needs.

[0005] In view of this, the present invention proposes a solar panel support sway warning device. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] The solar panel support sway warning device provided by the present invention has the following beneficial effects:

[0020] 1. When the device is affected by wind, causing the device to sway more, the motor starts and drives the lead screw to rotate, which in turn causes the storage rack box to slide inside the support cylinder. By sliding the storage rack into the support cylinder, the overall height of the device can be reduced, thereby lowering the overall center of gravity of the device and making it easier to maintain balance. Furthermore, due to the reduction in the overall height of the device, the area of ​​the device exposed to wind is reduced, and the lever arm of the device is also reduced, thus reducing the torque of the wind force on the device, thereby reducing the impact of wind force on the device, and ultimately reducing the sway amplitude.

[0021] 2. When the device shakes significantly, the storage rack slides into the support cylinder, which in turn moves the U-shaped pressure rod downwards. Driven by the pressure rod, the rotating rod and support rod rotate and unfold. When the device shakes back and forth, the unfolded legs can support it. The legs also increase the contact area between the device and the ground, thereby increasing the pressure-bearing area of ​​the device, providing more stable support, and thus improving the stability of the device, preventing it from overturning.

[0022] 3. When the mounting bolts loosen, the top frame may detach from the storage rack, causing it to fall from a height and impact the ground. The resulting reaction force could damage the top frame and the solar panels mounted on it, potentially injuring pedestrians nearby. The top frame can be secured by rotating the top of the connecting rod and engaging the slot, allowing maintenance personnel to arrive. This prevents unnecessary losses due to the top frame's detachment and improves the safety of pedestrians near the device.

[0023] 4. The alarm sound can signal to nearby staff that the device is shaking significantly. The knocking sound of the pillar and the knocking rod can attract the attention of pedestrians who are about to pass by, thus preventing them from avoiding the shaking device. This prevents pedestrians from being injured by the shaking device if they are not paying attention when the device shakes or falls over due to the large amplitude of the shaking. The dual warning effect of the alarm and the knocking sound of the pillar and the knocking rod greatly improves the warning effect, thereby attracting the attention of nearby pedestrians and preventing them from being injured by the shaking device.

[0024] 5. By using the triangular design of the triangular blocks, when the base is subjected to force and the insertion post moves upward, the triangular blocks will hinder the upward movement of the insertion post, increasing resistance and friction between the insertion post and the ground. This, in turn, improves the friction between the base and the installation ground, making the installation more secure. At the same time, the base is less likely to wobble when subjected to external forces. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides a technical solution:

[0038] Example 1

[0039] Please see Figures 1 to 6 A solar panel support sway warning device includes a base 1, a support cylinder 2 fixedly connected to the upper surface of the base 1, a motor 5 fixedly connected to the inner wall of the base 1, a storage rack 3 slidably connected to the inner wall of the support cylinder 2, a lead screw 6 rotatably connected to the bottom of the inner wall of the support cylinder 2, the output end of the motor 5 being fixedly connected to the bottom end of the lead screw 6, the lead screw 6 being threadedly connected to the bottom end of the storage rack 3, and U-shaped pressure rods 7 being slidably connected evenly and equidistantly through the outer surface of the support cylinder 2. Sliding columns 8 are symmetrically fixedly connected to the bottom of each U-shaped pressure rod 7, and each sliding column 8 is slidably connected to the support cylinder 2. A reset spring is sleeved on the outer surface of each sliding column 8. Spring 9 and U-shaped pressure rod 7 are symmetrically fixedly connected to guide rods 10. Guide grooves 11 are opened on the outer wall of guide rods 10. Rotating rods 12 are rotatably connected to the outer surface of support cylinder 2 at equal intervals. Guide blocks 13 are symmetrically fixedly connected to the outer wall of rotating rods 12. Guide blocks 13 are slidably connected to guide grooves 11. Support rods 14 are slidably connected to the outer wall of rotating rods 12. Guide columns 15 are fixedly connected to the outer wall of support rods 14. Guide frames 16 are symmetrically fixedly connected to the upper surface of base 1 at equal intervals. Guide holes 17 are opened on the outer wall of the top of guide frames 16. Both ends of guide columns 15 are slidably connected to guide holes 17.

[0040] The guide rod 10 is composed of a diagonal rod and a straight rod. The guide groove 11 and the guide hole 17 are both inclined. The control box 19 is fixedly connected to the outer surface of the support cylinder 2. The bottom of the inner wall of the control box 19 is inclined. The slider 20 is slidably connected to the bottom of the inner wall of the control box 19. Magnets 23 are fixedly connected to the right side of the slider 20 and the right side of the inner wall of the control box 19. An alarm is fixedly connected to the bottom of the control box 19. The second contact 22 is fixedly connected to the right side of the slider 20. The first contact 21 is fixedly connected to the right side of the inner wall of the control box 19. The first contact 21 and the second contact 22 are electrically connected to control the motor 5 and the alarm.

[0041] Compared with the prior art, this embodiment can reduce the overall height of the device by retracting the storage rack 3 into the support cylinder 2, thereby reducing the area of ​​the device exposed to wind force, thus reducing the wind's force on it and improving wind resistance. At the same time, in the event of a large sway, an alarm can be triggered, so that nearby staff can be notified and come to the scene. In contrast, existing technology devices cannot be retracted when a large sway occurs, resulting in poor wind resistance. Moreover, most devices are only inspected periodically, and when a sway occurs, it cannot be detected in time.

[0042] Example 2

[0043] Please see Figures 7 to 10 A solar panel support sway warning device includes a top frame 4 at the top of a storage rack 3. Two mounting bolts 24 are symmetrically threaded through the lower surface of the top of the storage rack 3, and both bolts 24 are threaded to the top frame 4. Connecting rods 25 are provided between the two mounting bolts 24 and the lower surface of the top of the storage rack 3. Fixing frames 26 are fixedly connected to both the front and rear sides of the storage rack 3. The connecting rods 25 are slidably connected through the outer walls of the fixing frames 26 on both the front and rear sides. Compression springs 27 are symmetrically fixedly connected to the upper surface of the connecting rods 25, and the tops of the compression springs 27 are fixedly connected to the fixing frames 26. Rotating connecting rods 28 are symmetrically rotatably connected to the outer walls of the fixing frames 26. Torsion springs are provided between the rotating connecting rods 28 and the fixing frames 26. The top frame 4 has two connecting rods 25 on both the front and rear sides. It is said that there are two slots 29. The connecting rod 25 is fixedly connected to the front and rear sides of the fixed rod 30. The outer wall of the fixed rod 30 is slidably connected to the locking post 31. The locking post 31 is locked to the outer wall of the fixed frame 26. The lower end of the screw 6 is fixedly connected to the protrusion 32 at equal intervals. The lower end of the support cylinder 2 is slidably connected to the striking post 33. The end of the striking post 33 near the protrusion 32 is in contact with the protrusion 32. The outer surface of the striking post 33 is sleeved with a connecting spring 34. The two ends of the connecting spring 34 are fixedly connected to the striking post 33 and the support cylinder 2 respectively. The bottom end of the support cylinder 2 is fixedly connected to the side near the striking post 33. The bottom end of the base 1 is fixedly connected to the insertion post 36 at equal intervals. The outer surface of the insertion post 36 is fixedly connected to the triangular block 37 at equal intervals.

[0044] Compared with the prior art, in this embodiment, when the mounting bolt 24 becomes loose, the locking effect between the rotating connecting rod 28 and the slot 29 is improved, thus enhancing the fixation effect between the storage rack 3 and the top rack 4. Furthermore, the setting of the bottom insert post 36 and the triangular block 37 of the base 1 increases the resistance when the base 1 is subjected to external force, and also increases the friction between the base 1 and the ground during installation. In contrast, the existing technology has a simple base 1 structure, which is prone to loosening under long-term external force. Moreover, when the mounting bolt 24 becomes loose, there is no temporary fixing structure, which may cause the top rack 4 to fall off the storage rack 3, resulting in losses and endangering the safety of nearby pedestrians.

[0045] The following is the complete working process of the above embodiments:

[0046] Before installation: First, after the base 1 is installed, the insertion post 36 is inserted into the ground through the setting of the insertion post 36 and the triangular block 37. The triangular setting of the triangular block 37 ensures that when the base 1 is subjected to force, the insertion post 36 moves upward, and the triangular block 37 hinders the upward movement of the insertion post 36, increasing resistance and friction between the insertion post 36 and the ground. This, in turn, improves the friction between the base 1 and the installation ground, making the installation more secure. Simultaneously, the base 1 is less prone to wobbling when subjected to external forces. Second, during the installation of the top frame 4, the fixing rod 30 is first slid upward, so that the fixing rod 30 is aligned with the upper end of the storage rack 3. The surfaces are fitted together, and then the locking post 31 is pushed to slide towards the fixing frame 26 and engage with the fixing frame 26. At this time, the compression spring 27 is in a compressed state. Then the top frame 4 can be placed on top of the storage rack 3. Then the storage rack 3 and the top frame 4 can be installed by the mounting bolt 24. After installation, the locking post 31 can be slid in the opposite direction to the fixing frame 26 to disengage the locking post 31 from the fixing frame 26. Because of the support of the mounting bolt 24, the connecting rod 25 is located between the mounting bolt 24 and the lower surface of the upper end of the storage rack 3, so the connecting rod 25 will not slide down at this time, and the compression spring 27 is still in a compressed state.

[0047] During operation, because the top frame 4 is located at the top of the device, the connection between the top frame 4 and the storage rack 3 is significantly affected by wind. When the installation bolt 24 loosens and slides down due to the wind, a gap appears between the installation bolt 24 and the lower surface of the upper end of the storage rack 3. At this time, under the rebound force of the compression spring 27, the connecting rod 25 moves down simultaneously with the installation bolt 24, causing both sides of the connecting rod 25 to press down on the bottom end of the rotating connecting rod 28. This causes the top end of the rotating connecting rod 28 to rotate towards the top frame 4, thereby engaging the top end of the rotating connecting rod 28 with the slot 29, thus increasing the connection between the storage rack 3 and the top frame 4. The fixing effect between the top frame 4 and the storage frame 3 is to prevent the top frame 4 from falling from a height and impacting the ground when the mounting bolt 24 is loose. The reaction force caused by the impact would damage the top frame 4 and the solar panels installed on the top frame 4, and may also cause injury to pedestrians if they pass by. The consequences are quite serious. By rotating the top of the connecting rod 28 and engaging it with the slot 29, the top frame 4 can be fixed, so that it can wait for the staff to carry out maintenance. This prevents unnecessary losses caused by the failure of the top frame 4 and improves the safety of pedestrians near the device.

[0048] Furthermore, when the device experiences significant shaking due to prolonged wind, the base 1, support cylinder 2, storage rack 3, and top frame 4 simultaneously shake. At this time, the bottom slope of the control box 19 tilts to either parallel to or in the opposite direction to the ground due to the shaking. This causes the slider 20 to move the second contact 22 and the magnet 23 on the slider 20 towards the first contact 21. The two magnets 23 then attract each other using the principle of opposite poles attracting. At this point, the first contact 21 and the second contact 22 come into contact and connect, triggering the alarm. Simultaneously, the second contact 21... Contact 21 and contact 22 make contact and connect, starting motor 5. Motor 5 drives lead screw 6 to rotate, causing storage rack 3 to slide into support cylinder 2. This sliding of storage rack 3 into support cylinder 2 reduces the overall height of the device, lowering its center of gravity and making it easier to maintain balance. Furthermore, the reduced height decreases the area exposed to wind, shortening the lever arm and reducing the torque exerted by wind, thus minimizing the impact of wind and ultimately reducing the amplitude of swaying. The moving top frame 4 moves downwards, and as the lead screw 6 rotates, it drives the protrusions 32 to rotate. This causes the multiple protrusions 32 to push the striking column 33, thus causing the striking column 33 to move towards the striking rod 35 under the pressure of the protrusions 32, and compressing the connecting spring 34. When the protrusions 32 and the striking column 33 are misaligned, the striking column 33 returns to its original position under the rebound of the connecting spring 34. Thus, as the lead screw 6 drives the protrusions 32 to rotate continuously, and in cooperation with the connecting spring 34, the striking column 33 continuously strikes the rod 35, producing a sound. This sound can be detected by the alarm. The device signals nearby staff that it is shaking significantly. The sound of striking the post 33 and the striking rod 35 can attract the attention of pedestrians who are about to pass by, thus preventing them from avoiding the shaking device. This prevents pedestrians from being injured by the shaking device if they are not paying attention when the device shakes or falls over due to the large amplitude of the shaking. The dual warning effect of the alarm and the sound of striking the post 33 and the striking rod 35 greatly enhances the warning effect, thereby attracting the attention of nearby pedestrians and preventing them from being injured by the shaking device.

[0049] Furthermore, as the storage rack 3 slides into the support cylinder 2, the bottom end of the storage rack 3 gradually contacts the portion of the U-shaped pressure rod 7 located inside the support cylinder 2, and presses down on the U-shaped pressure rod 7. This causes the U-shaped pressure rod 7, guided by the sliding column 8, to move the sliding column 8 downwards simultaneously, thus compressing the return spring 9. As the U-shaped pressure rod 7 moves downwards, it simultaneously drives the guide rod 10 and the guide groove 11 downwards. Under the pressure and guidance of the guide groove 11 on the guide block 13, the rotating rod 12 gradually rotates outwards around its top end. Simultaneously, as the rotating rod 12 rotates and unfolds, it drives the support rod 14 to rotate and unfold. When the support rod 14 rotates and unfolds, under the guidance and compression of the guide post 15 by the guide hole 17, the support rod 14 moves downward along the rotating rod 12 while the rotating rod 12 drives the support rod 14 to rotate. Thus, while the rotating rod 12 drives the support rod 14 to rotate, the bottom end of the support rod 14 contacts the ground. Thus, through the rotation and unfolding of the rotating rod 12 and the support rod 14, the unfolded outriggers can support the device when it shakes back and forth. The outriggers increase the contact area between the device and the ground, thereby increasing the pressure-bearing area of ​​the device, providing a more stable support force, and thus improving the stability of the device, preventing it from overturning.

[0050] Furthermore, when the staff arrives for maintenance, they can reset the slider 20 by opening the control box 19, thereby triggering the alarm. At the same time, when the motor 5 is started, the storage rack 3 drives the top rack 4 to rise and reset. As the bottom of the storage rack 3 rises, the pressure on the U-shaped pressure rod 7 is gradually reduced and canceled. Under the return spring 9, the U-shaped pressure rod 7 and the sliding column 8 are reset, thereby driving the rotating rod 12 and the support rod 14 to reset.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
