Abstract

The present invention relates to the field of photovoltaic brackets, and specifically discloses a photovoltaic bracket with a structure for resisting the impact of falling objects. In this application, the second plate frame is rotatably connected to the first plate frame through the first fixed shaft, so that when the upper part of the photovoltaic panel is subjected to a falling impact, the falling impact can be relieved by rotating and swinging. During the rotation and swinging process, with the help of the frictional damping between the first through groove and the second fixed shaft and the weakening and absorption of the force by the elastic deformation of the first straight spring, the collision effect of the falling impact acting on the photovoltaic panel is weakened. At the same time, during the deflection process, the first water supply mechanism is triggered to start, forming a water flow scouring on the upper surface of the photovoltaic panel, which can not only clean the photovoltaic panel, but also weaken the falling impact force by the side scouring of the water flow. With the mutual cooperation, the performance of the device for resisting the impact of falling objects can be effectively improved, which is beneficial to the protection of the photovoltaic panel.

Description

Technical Field

[0001] The present application relates to the field of photovoltaic brackets, and particularly to a photovoltaic bracket with a structure for resisting the impact of falling objects. Background Art

[0002] A photovoltaic bracket is a support structure for placing, installing, and fixing solar photovoltaic panels in a solar power generation system. It is generally made of aluminum alloy, carbon steel, or stainless steel and is an important part of the solar power generation system.

[0003] In the prior art, the structure of the photovoltaic bracket is usually relatively simple and fixed. When the photovoltaic panel is impacted by a falling object from above, the photovoltaic panel directly faces the falling impact force and cannot buffer and weaken the falling impact. This makes the solar photovoltaic panel installed at the top and supported most likely to be damaged due to excessive falling impact force during a falling impact, affecting the service life of the photovoltaic panel.

[0004] Therefore, a photovoltaic bracket with a structure for resisting the impact of falling objects is proposed to solve some problems existing in the above prior art. Summary of the Invention

[0009] Further, a second spray pipe arranged horizontally is fixedly installed at the front end of the mounting frame, and a large number of spray holes are also evenly distributed on the side of the second spray pipe close to the mounting frame. The second spray pipe is externally connected with a second water supply mechanism.

[0010] Further, the tops of the first spray pipe and the second spray pipe are both arranged in an arc-shaped structure, the outer shape of the spray holes is arranged in a flat horn-shaped structure, and a one-way valve is fixedly installed in the spray holes.

[0011] Further, the second water supply mechanism includes a second connection box a fixedly installed at the front end of the third plate frame, and a second hollow shaft coaxially arranged with the second fixed shaft is rotatably communicated with the second connection box a. A second connection box b sleeved outside the second hollow shaft is fixedly installed at the front end of the first plate frame, and a second sleeve movably sleeved outside the second hollow shaft is fixedly installed in the second connection box b.

[0014] Furthermore, a first solenoid valve is fixedly installed in the first water connection pipe, and a second solenoid valve is fixedly installed in the second water connection pipe.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] (1) In the present application, the second plate frame is rotatably connected to the first plate frame through the first fixed shaft, so that when a falling impact occurs above the photovoltaic panel, the falling impact can be dissipated through rotational swinging. During the rotational swinging process, with the help of the frictional damping between the first through groove and the second fixed shaft and the weakening and absorption of force by the elastic deformation of the first straight spring, the collision effect of the falling impact acting on the photovoltaic panel is weakened. At the same time, during the deflection process, the first water supply mechanism is triggered to start, and a water flow is formed to wash the upper surface of the photovoltaic panel. It can not only clean the photovoltaic panel, but also weaken the falling impact force by the side washing of the water flow. With the mutual cooperation, the performance of the device against falling object impact can be effectively improved, which is beneficial to the protection of the photovoltaic panel.

[0017] (2) The third plate frame is rotatably connected to the first plate frame through the second fixed shaft, and the second fixed shaft and the first fixed shaft are respectively arranged at the front and rear ends of the first plate frame. When the photovoltaic panel is subjected to a falling impact, the second plate frame and the first plate frame can deflect and swing nearby. During the swinging process of the first plate frame, with the help of the damping of the sliding friction between the third fixed shaft and the second through groove and the elastic support of the second straight spring, and in cooperation with the buffering during the swinging process of the second plate frame, the falling impact from above can be more comprehensively weakened and absorbed, which is beneficial to further improving the anti-falling impact effect of the device.

[0018] (3) By arranging the first slider between the second fixed shaft and the first straight spring and arranging the second slider between the third fixed shaft and the second straight spring, the elastic support of the first straight spring and the second straight spring will not affect the rotation of the second fixed shaft and the third fixed shaft, which is beneficial to ensuring the stability of the device during operation.

[0019] (4) By providing a second water supply mechanism, during the swinging process of the first plate frame, water can be supplied to the second nozzle at the front end by triggering the second water supply mechanism. With the first solenoid valve installed in the first water connection pipe and the second solenoid valve installed in the second water connection pipe, when either the first plate frame or the second plate frame triggers deflection, only water flow in one direction will be controlled to spray out, which is beneficial for ensuring the cleaning of the photovoltaic panel by the impact of water flow and buffering the falling impact.

[0020] (5) By setting the tops of the first nozzle and the second nozzle as arc-shaped structures, falling objects can easily pass over, which is beneficial for avoiding the accumulation of foreign objects and blocking at the first nozzle and the second nozzle. At the same time, by setting the shape of the spray hole as a flat horn-shaped structure, under the guidance of the spray hole, the sprayed water flow presents a fan-shaped structure, which is beneficial for improving the comprehensiveness of the water flow covering the surface of the photovoltaic panel. By installing a check valve in the spray hole, the probability of foreign objects entering the first nozzle and the second nozzle through the spray hole can be reduced, avoiding the blockage of the first nozzle and the second nozzle due to the entry of foreign objects.

[0021] (6) Through the cooperation of the arc-shaped frame and the arc-shaped groove, the third plate frame can rotate relative to the base, and with the drive of the servo motor, when the photovoltaic panel is enabled, the tilt angle of the photovoltaic panel can be flexibly adjusted according to the position of the sun, ensuring that the photovoltaic panel always faces the sun directly. At the same time, relying on the self-locking property of the meshing between the worm and the worm gear, the angle of the photovoltaic panel is automatically fixed firmly after adjustment, effectively ensuring the stability of the photovoltaic panel during actual use.

[0022] (7) By providing a first torsion spring and a second torsion spring, when facing a falling impact, the falling impact can also be buffered and absorbed by means of the frictional damping between the first fixed shaft and the second plate frame and the elastic support of the first torsion spring, and by means of the frictional damping between the second fixed shaft and the first plate frame and the elastic support of the second torsion spring. With their mutual cooperation, the anti-falling object impact effect of the device can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The embodiments will be described clearly and completely in conjunction with the accompanying drawings of the specification. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of this application.

[0038] The present invention provides a photovoltaic bracket with a structure for resisting the impact of falling objects. Please refer to Figure 1 - Figure 12 , which includes a base 1. A first plate frame 101 with a downwardly inclined front end is installed on the base 1. A horizontally arranged first fixed shaft 102 is rotatably installed at the rear end of the first plate frame 101. A second plate frame 103 with a downwardly inclined front end is rotatably connected above the first plate frame 101 through the first fixed shaft 102. A first arc-shaped rod 104 is fixedly installed at the front end of the second plate frame 103. A first through groove 105 coaxial with the first fixed shaft 102 is formed in the first arc-shaped rod 104. A horizontally arranged second fixed shaft 106 is fixedly installed at the front end of the first plate frame 101. The second fixed shaft 106 is movably inserted into the first through groove 105. A first straight spring 107 for elastically supporting the second fixed shaft 106 is installed in the first through groove 105. An installation frame 2 is fixedly installed at the top of the second plate frame 103. The photovoltaic panel is fixedly covered on the top of the installation frame 2. A horizontally arranged first nozzle 201 is fixedly installed at the rear end of the installation frame 2. A plurality of spray holes 202 are evenly distributed on one side of the first nozzle 201 close to the installation frame 2. The first nozzle 201 is externally connected to a first water supply mechanism.

[0039] During the use of the device, supported by the second plate frame 103, the mounting frame 2 is in a state where the front end slopes downward. This causes the photovoltaic panels evenly covering the top of the mounting frame 2 to be in an inclined state, enabling the photovoltaic panels to receive sunlight more efficiently during operation. When an object falls from above in the air above the photovoltaic panels, since the second plate frame 103 is rotatably connected to the first plate frame 101 through the first fixed shaft 102, the second fixed shaft 106 is movably inserted into the first through groove 105 and elastically supported by the first straight spring 107. When the object's fall impacts the photovoltaic panels, under the impact from above, it will cause the second plate frame 103 to deflect downward around the first fixed shaft 102, transferring the fall impact by means of the deflection. During the deflection process, with the help of the frictional damping between the first through groove 105 and the second fixed shaft 106 and the elastic support of the first straight spring 107, the fall impact force is weakened and absorbed, effectively improving the device's anti-fall impact protection performance for the photovoltaic panels. When the second plate frame 103 deflects, it will trigger the first water supply mechanism. After being triggered, the first water supply mechanism supplies water into the first spray pipe 201, and the water jets out through the spray holes 202 evenly distributed on the first spray pipe 201, horizontally jetting out along the upper surface of the photovoltaic panels on the top of the mounting frame 2. During the water jet process, not only can the upper surface of the photovoltaic panels be cleaned, but also the object falling on the upper surface of the photovoltaic panels can be washed away by means of the water impact. The horizontally jetting water acts on the falling object, applying a force to the falling object from the side, assisting in weakening the impact force of the falling object on the photovoltaic panels and further improving the anti-fall impact effect of the device.

[0040] Please refer to Figure 6 、 Figure 8 and Figure 11 As shown in, the first water supply mechanism includes a first connection box a3 fixedly installed at the rear end of the first plate frame 101, and a first hollow shaft 301 coaxially arranged with the first fixed shaft 102 is rotatably connected to the first connection box a3. A first connection box b302 sleeving the outside of the first hollow shaft 301 is fixedly installed at the rear end of the second plate frame 103, and a first sleeve 303 movably sleeving the outside of the first hollow shaft 301 is fixedly installed inside the first connection box b302. A first docking hole a304 evenly distributed in a circular pattern is formed on the end wall of the first hollow shaft 301, and a first docking hole b305 adapted to the first docking hole a304 is formed on the end wall of the first sleeve 303. A first water connection pipe 306 is externally connected to the first connection box a3, and the inside of the first connection box b302 is connected to the first spray pipe 201.

[0041] During the use of the device, when the second plate frame 103 deflects due to dissipating the force of the falling object above, it will drive the first connection box b302 to rotate synchronously around the first fixed shaft 102. Since the first hollow shaft 301 is coaxially arranged with the first fixed shaft 102, this causes the first connection box b302 to rotate around the first hollow shaft 301. During the rotation of the first connection box b302, it drives the first sleeve 303 to rotate synchronously, causing the first sleeve 303 to rotate relative to the first hollow shaft 301. When not rotating, the first docking hole b305 opened on the end wall of the first sleeve 303 is not aligned with the first docking hole a304 opened on the end wall of the first hollow shaft 301. When the first sleeve 303 rotates relative to the first hollow shaft 301, due to the rotation of the first sleeve 303, the first docking hole b305 is misaligned and then aligned with the first docking hole a304 opened on the end wall of the first hollow shaft 301. At this time, the water flow supplied in the external first water connection pipe 306 enters the first connection box a3, and by means of the connection between the first docking hole a304 and the first docking hole b305, it will enter the first connection box b302 through the first hollow shaft 301. Subsequently, the water flow enters the first spray pipe 201 from the first connection box b302 through the connection of the pipeline and is sprayed out through the spray holes 202 opened on the first spray pipe 201. During the process of dissipating the force of the falling object, the operations of spraying water for cleaning and assisting in dissipating the force are carried out synchronously.

[0042] Please refer to Figure 5 and Figure 11 , a third plate frame 4 parallel to the second plate frame 103 is rotatably connected to the lower part of the first plate frame 101 through a second fixed shaft 106. A second arc-shaped rod 401 is fixedly installed at the rear end of the third plate frame 4, and a second through groove 402 coaxially arranged with the second fixed shaft 106 is opened in the second arc-shaped rod 401. A third fixed shaft 403 horizontally inserted into the second through groove 402 is fixedly installed at the rear end of the third plate frame 4. A second straight spring 404 for elastically supporting the third fixed shaft 403 is installed in the second through groove 402.

[0043] During the use of the device, when the falling position of the falling object is above the photovoltaic panel, since the falling position of the falling object is close to the first fixed shaft 102, the amplitude of the rotation of the second plate frame 103 driven by the falling impact is greatly reduced, the rotation angle of the second plate frame 103 is greatly decreased, and the buffering of the falling impact is greatly weakened. At this time, since the front end of the first plate frame 101 is rotationally connected to the third plate frame 4 through the second fixed shaft 106, when a falling impact occurs above the photovoltaic panel, it will drive the first plate frame 101 to deflect downward relative to the third plate frame 4 around the second fixed shaft 106. During this process, the third fixed shaft 403 slides in the second through groove 402. With the damping of the sliding friction between the third fixed shaft 403 and the second through groove 402 and the elastic support of the second straight spring 404, the falling impact force from above can be greatly weakened and absorbed. When the photovoltaic panel is subjected to a falling impact, by means of the deflection of the second plate frame 103 around the first fixed shaft 102 relative to the first plate frame 101 and the deflection of the first plate frame 101 around the second fixed shaft 106 relative to the third plate frame 4, the falling impact from above can be more comprehensively weakened and absorbed, further improving the anti-falling-object impact effect of the device.

[0044] A first slider 108 fixedly connected to a first straight spring 107 is slidably installed in the first through groove 105, and the first slider 108 is rotationally connected to the second fixed shaft 106. A second slider 405 fixedly connected to a second straight spring 404 is slidably installed in the second through groove 402, and the second slider 405 is rotationally connected to the third fixed shaft 403. During the use of the device, the first slider 108 is slidably installed in the first through groove 105 for connecting the first straight spring 107 and the second fixed shaft 106, so that when the first straight spring 107 elastically supports the second fixed shaft 106, it will not affect the rotation of the second fixed shaft 106. At the same time, the second slider 405 is slidably installed in the second through groove 402 for connecting the second straight spring 404 and the third fixed shaft 403, so that when the second straight spring 404 elastically supports the third fixed shaft 403, it will not affect the rotation of the third fixed shaft 403. With the above structure in cooperation, the stability of the device during operation can be effectively improved.

[0045] Please refer to Figure 1 、 Figure 7 and Figure 9, a horizontally arranged second nozzle 203 is fixedly installed at the front end of the mounting frame 2, and a plurality of spray holes 202 are also evenly distributed on the side of the second nozzle 203 close to the mounting frame 2. The second nozzle 203 is externally connected to a second water supply mechanism. The tops of the first nozzle 201 and the second nozzle 203 are both set as arc-shaped structures. The outer shape of the spray hole 202 is set as a flat horn-shaped structure. A check valve is fixedly installed in the spray hole 202. The second water supply mechanism includes a second connection box a5 fixedly installed at the front end of the third plate frame 4, and a second hollow shaft 501 coaxially arranged with the second fixed shaft 106 is rotationally connected to the second connection box a5. A second connection box b502 sleeved outside the second hollow shaft 501 is fixedly installed at the front end of the first plate frame 101. A second sleeve 503 movably sleeved outside the second hollow shaft 501 is fixedly installed in the second connection box b502. Second docking holes a504 are formed in a circumferential distribution on the end wall of the second hollow shaft 501. Second docking holes b505 adapted to the second docking holes a504 are formed in the end wall of the second sleeve 503. The second connection box a5 is externally connected to a second water connection pipe 506. The inside of the second connection box b502 is communicated with the second nozzle 203.

[0046] During the use of the device, when the first plate frame 101 and the third plate frame 4 deflect due to the impact of floating and falling, the first plate frame 101 rotates around the second fixed shaft 106 relative to the third plate frame 4, which will drive the second connection box b502 to rotate around the second fixed shaft 106. Since the second hollow shaft 501 is coaxially arranged with the second fixed shaft 106, when deflecting, the second connection box b502 will rotate relative to the second hollow shaft 501, driving the second sleeve 503 to rotate relative to the second hollow shaft 501. Normally, the second docking holes b505 formed in the end wall of the second sleeve 503 are not communicated with the second docking holes a504 formed in the end wall of the second hollow shaft 501. When the second sleeve 503 rotates relative to the second hollow shaft 501, due to rotational misalignment, the second docking holes b505 will be aligned and communicated with the second docking holes a504. At this time, water flows into the second hollow shaft 501 through the second water connection pipe 506 externally connected to the second connection box a5. Through the communication of the second docking holes a504 and the second docking holes b505, the water flows into the second connection box b502, and then is transported into the second nozzle 203 and sprayed out through the spray holes 202 evenly formed on the second nozzle 203. The water flow sprayed out from the second nozzle 203 can also act on the photovoltaic panel to clean the photovoltaic panel, and the sprayed water flow impacts on the falling object, impacting the falling object from the side, changing the falling force of the falling object from top to bottom, and assisting in buffering the falling object.

[0047] By setting the tops of both the first nozzle 201 and the second nozzle 203 to be arc-shaped structures, it enables foreign objects falling on the upper surface of the photovoltaic panel to easily cross over the first nozzle 201 and the second nozzle 203 when sliding along the inclined plane, avoiding the accumulation and jamming of foreign objects at the first nozzle 201 and the second nozzle 203, which is beneficial to ensuring the stability during the use of the photovoltaic panel. During the use process, by setting the shape of the spray hole 202 to be a flat horn-shaped structure, it enables the water flow ejected from the spray hole 202 to be ejected in a fan shape, which is beneficial to enhancing the comprehensiveness of the water flow acting on the surface of the photovoltaic panel. The reason for installing a one-way valve in the spray hole 202 is to prevent foreign objects from entering the first nozzle 201 and the second nozzle 203 through the spray hole 202, avoiding the blockage of the first nozzle 201 and the second nozzle 203 due to the entry of foreign objects, and ensuring the stability of the device during operation to a certain extent.

[0048] Please refer to Figure 5 、 Figure 8 and Figure 12 As shown in, an arc-shaped frame 6 is fixedly installed at the middle position of the bottom of the third plate frame 4. Arc-shaped grooves 601 adapted to the arc-shaped frame 6 are formed on the left and right side walls of the base 1. The arc-shaped frame 6 is slidably inserted into the arc-shaped groove 601. An arc-shaped rack 602 coaxially arranged with the arc-shaped frame 6 is fixedly installed at the bottom of the third plate frame 4. A gear 603 meshing with the arc-shaped rack 602 is rotatably installed in the base 1. A servo motor 604 is fixedly installed in the base 1, and a worm 605 is fixedly installed on the drive shaft of the servo motor 604. A worm gear 606 coaxially connected with the gear 603 is meshed below the worm 605.

[0049] During the use of the device, during the continuous change of the sun's position, the tilt angle of the photovoltaic panel installed on the top of the mounting frame 2 will continuously deflect and adjust. During this process, the servo motor 604 is powered on and starts, driving the worm 605 fixedly connected to its drive shaft to rotate. Subsequently, by means of the meshing of the worm 605 and the worm gear 606, the worm gear 606 is driven to rotate, driving the gear 603 to rotate. By means of the meshing of the gear 603 and the arc-shaped rack 602, the third plate frame 4 is driven to rotate along the axial position of the arc-shaped frame 6, continuously changing the tilt angle of the upper photovoltaic panel during the rotation process. During the adjustment of the tilt angle of the photovoltaic panel, due to the self-locking property of the meshing between the worm 605 and the worm gear 606, the angle of the photovoltaic panel can be automatically fixed after adjustment, which is beneficial to the stability of the photovoltaic panel after the angle adjustment.

[0050] Please refer to Figure 10 As shown in, a first torsion spring 7 elastically supported between the first plate frame 101 and the second plate frame 103 is sleeved outside the first fixed shaft 102. A second torsion spring 701 elastically supported between the first plate frame 101 and the third plate frame 4 is sleeved outside the second fixed shaft 106.

[0051] During the use of the device, when the second plate frame 103 and the first plate frame 101 deflect relative to each other around the first fixed shaft 102, not only can the friction damping between the first through groove 105 and the second fixed shaft 106 and the elastic support of the first straight spring 107 be used to buffer and absorb the falling impact, but also the friction damping between the first fixed shaft 102 and the second plate frame 103 and the elastic support of the first torsion spring 7 can be used to buffer and absorb the falling impact. Similarly, when the first plate frame 101 and the third plate frame 4 deflect relative to each other around the second fixed shaft 106, not only can the friction damping between the second through groove 402 and the third fixed shaft 403 and the elastic support of the second straight spring 404 be used to buffer and absorb the falling impact, but also the friction damping between the second fixed shaft 106 and the first plate frame 101 and the elastic support of the second torsion spring 701 can be used to buffer and absorb the falling impact. With mutual cooperation, the anti-falling object impact effect of the device can be further improved.

[0052] Please refer to Figure 5 , a first solenoid valve 8 is fixedly installed in the first water connection pipe 306, and a second solenoid valve 801 is fixedly installed in the second water connection pipe 506. During the use of the device, when the falling position of the falling object is closer to the second fixed shaft 106, the first solenoid valve 8 in the first water connection pipe 306 is in an open state, and the second solenoid valve 801 in the second water connection pipe 506 is in a closed state. This enables the first water supply mechanism to stably supply water to the first spray pipe 201 after being triggered, while the second water supply mechanism will not supply water to the second spray pipe 203 even after being triggered. When the falling position of the falling object is closer to the first fixed shaft 102, the first solenoid valve 8 in the first water connection pipe 306 is in a closed state, and the second solenoid valve 801 in the second water connection pipe 506 is in an open state. This enables the first water supply mechanism not to supply water to the first spray pipe 201 even after being triggered, and the second water supply mechanism can stably supply water to the second spray pipe 203 after being triggered. With such operations, with the auxiliary impact of water flow, the falling object can be better pushed out of the top of the photovoltaic panel, making the operation of the device more reasonable and stable.

[0053] The above is only the best implementation mode adopted by the present application in combination with the current actual needs, but the protection scope of the present application is not limited thereto.
