Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic panel bracket and a photovoltaic device. Background Art

[0002] The photovoltaic panel bracket is a support body used to install photovoltaic panels. It consists of a base frame and a carrier. The photovoltaic panels are fixed on the carrier. The carrier is generally inclined. The photovoltaic panels are installed on the carrier for easy tilting display in the sun to improve light energy absorption. The base frame is fixed to the building by bolts or loads to improve strength.

[0003] Since photovoltaic panels are installed in an inclined manner on an elevated position by photovoltaic racks, their photovoltaic surface is not only the surface facing the light, but also the windward surface when strong winds come. If the windward surface cannot automatically unload the force when attacked by wind, both the photovoltaic panels themselves and the photovoltaic racks will bear greater attack force, and the destructive force they will suffer will also increase, affecting their service life. Summary of the invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] A photovoltaic panel support, comprising a base frame, a guide rail is provided on the base frame, a top frame capable of sliding back and forth is mounted on the base frame through the guide rail, a carrier moving back and forth with the top frame is mounted on the top frame, a photovoltaic panel moving back and forth with the carrier is mounted on the top surface of the carrier, a gear moving back and forth with the carrier is mounted on the end of the carrier, a rack on the same side as the gear is mounted on the base frame, the rack is located on the moving path of the gear, when the gear moves to contact with the rack, the rack meshes with the gear to rotate, and the gear drives the carrier to deflect downward, and the carrier drives the photovoltaic panel to deflect downward, so that the height of the photovoltaic panel is automatically reduced;

[0006] A vertically upward support rod is installed on the other end of the top frame away from the gear, and the carrier is divided into two parts at two-thirds, and the two parts of the carrier are hinged together by a hinge relationship. The photovoltaic panel consists of two pieces, one photovoltaic panel is installed on two-thirds of the carrier, and the other photovoltaic panel is installed on one-third of the carrier. When the entire carrier is deflected to the maximum position, its bottom surface can fall on the support rod to form a bottom support, and under the support effect of the support rod on the bottom of the carrier, the two parts of the carrier are deflected downward again around the hinge position from the support point to further reduce the height of the photovoltaic panel.

[0007] As a further preferred embodiment, a first limiting tube is welded to one end of the top surface of the base frame, and a second limiting tube is welded to the other end of the top surface of the base frame. The gear is on the same side of the first limiting tube, and a rubber rod is fixed on the same side of the top frame and the gear. The rubber rod extends perpendicular to the direction of the first limiting tube and exceeds the gear.

[0008] As a further preferred embodiment, the second position limiting tube is on the same side as the support rod, a guide rod is welded to the second position limiting tube, a slide plate is welded on the same side end of the top frame and the support rod, the slide plate is slidably fitted on the guide rod, a support spring is mounted on the guide rod, and both ends of the support spring are elastically supported between the slide plate and the second position limiting tube.

[0009] As a further preference, a pulley is installed on the top frame, and there are several pulleys which are equidistantly arranged along the length direction of the top frame, and the pulleys are slidably fitted in the guide rails on the bottom frame.

[0010] As a further preferred embodiment, the rack is located in the middle position of the base frame. When the support spring releases the maximum elastic force, the top frame is pushed to the starting position along the base frame through the slide. At this time, the carrier brings the gear back to the starting position and moves the gear away from the rack.

[0011] As a further preferred embodiment, a rotating sleeve is welded on the bottom surface of the carrier, the rotating sleeve is close to one end on which the gear is installed, a rotating arm is installed on the rotating sleeve, a pin is welded on the top frame, the pin is located between the gear and the rotating sleeve, the other end of the rotating arm is tilted downward and then connected to the pin, a pull plate is welded on the carrier and the rotating arm, a tension spring is connected between the two pull plates, and the tension spring provides a pulling force to the rotating arm under the pulling action of the pull plate on the carrier, so as to deflect and pull up the end of the rotating arm connected to the rotating sleeve upward, and the carrier is pulled up to the deflected upward position by the end of the rotating arm connected to the rotating sleeve.

[0012] As a further preferred embodiment, there are two bottom frames, which are symmetrically arranged on both sides of the carrier, and there are two top frames, each of which is equipped with a row of pulleys and slides on the two bottom frames respectively through the pulleys, and the tension springs are installed on the two top frames in the same manner, and the other ends of the two tension springs are connected to the carrier in the same manner, the rack is installed on at least one of the bottom frames, and the gear is installed on at least one side of the carrier.

[0013] The present invention also provides a photovoltaic device, which is suitable for the photovoltaic panel bracket as described above, including an electrical box fixed on the base frame, a circuit connected in series between two photovoltaic panels, the output end of the circuit is connected to the electrical box, and at least an energy storage unit and an energy conversion unit are provided in the electrical box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When strong wind hits the photovoltaic panel, the photovoltaic panel pushes the carrier to move, and the carrier moves the top frame, and the top frame moves the gear. At the same time, the skateboard will move along and slide along the guide rod, and will squeeze the support spring to compress and shorten the support spring. When the gear moves to contact with the rack, the gear will be engaged and rotated by the rack, and the gear will deflect the carrier downward, and the carrier will deflect the photovoltaic panel downward, so that the photovoltaic panel is lowered from its original height position. Since the height position of the photovoltaic panel is lowered by deflecting downward at this time, it is equivalent to that the windward side of the photovoltaic panel is less affected by strong winds, and the destructive force it suffers is reduced. At this time, the photovoltaic panel achieves the purpose of automatic unloading and wind protection. However, when the wind intensity is reduced, the intensity of wind attack on the photovoltaic panel will also decrease. At this time, the force provided by the photovoltaic panel to the carrier will also become smaller, the thrust provided by the carrier to the top frame will also decrease, and the pressure of the slide plate on the support spring will also decrease. At this time, the support spring will release its length and provide reverse thrust to the slide plate while releasing its length, forcing the slide plate to move in the opposite direction with the top frame, and the top frame will reset the carrier in the opposite direction. While the carrier resets the gear in the opposite direction, the gear will mesh with the rack and rotate in the opposite direction. Under the action of the gear reversal, the carrier will be deflected upward again, and the carrier will rotate the photovoltaic panel upward to the angle where it receives light. With the change of the strong wind level, the degree of the top frame moving back and forth is not completely fixed. It only means that when the wind is strong, the top frame will move to unload the force of the photovoltaic panel. When the wind is stronger, the degree of movement of the top frame will be greater, so that when the carrier unloads the force of the photovoltaic panel, it is possible to move the gear to continuously mesh with the rack and complete the downward deflection, further improving the unloading effect. In any case, the photovoltaic panel can achieve automatic unloading protection when it is attacked by strong winds. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, Figure 1-Figure 9As shown: This embodiment provides a photovoltaic panel bracket and a photovoltaic device, including a base frame 1, a guide rail 2 is provided on the base frame 1, a top frame 3 that can slide back and forth is installed on the base frame 1 through the guide rail 2, a carrier 4 that moves back and forth with it is installed on the top frame 3, a photovoltaic panel 5 that moves back and forth with it is installed on the top surface of the carrier 4, a gear 6 that moves back and forth with it is installed at the end of the carrier 4, a rack 7 on the same side as the gear 6 is installed on the base frame 1, the rack 7 is located on the moving route of the gear 6, when the gear 6 moves to contact with the rack 7, the rack 7 meshes with the gear 6 to rotate, and the gear 6 leads the carrier 4 to deflect downward, and the carrier 4 leads the photovoltaic panel 5 to deflect downward, so that the height of the photovoltaic panel 5 is automatically reduced;

[0028] A vertically upward support rod 8 is installed on the other end of the top frame 3 away from the gear 6, and the carrier 4 is divided into two parts at two-thirds, and the two parts of the carrier 4 are hinged together through a hinge relationship. The photovoltaic panel 5 is divided into two pieces, one photovoltaic panel 5 is installed on the two-thirds part of the carrier 4, and the other photovoltaic panel 5 is installed on the one-third part of the carrier 4. When the entire carrier 4 is deflected to the maximum position, the bottom surface of the carrier 4 can fall on the support rod 8 to form a bottom support, and under the support effect of the support rod 8 on the bottom of the carrier 4, the two parts of the carrier 4 are deflected downward again around the hinge position from the support point, so as to further reduce the height of the photovoltaic panel 5;

[0029] The second position limiting tube 10 is on the same side as the support rod 8, and a guide rod 11 is welded to the second position limiting tube 10. A slide plate 12 is welded to the same side end of the top frame 3 and the support rod 8. The slide plate 12 is slidably fitted on the guide rod 11, and a support spring 13 is mounted on the guide rod 11. The two ends of the support spring 13 are elastically supported between the slide plate 12 and the second position limiting tube 10.

[0030] During normal use, the carrier 4 is tilted upward and displays the photovoltaic panel 5 in a sunlight environment in an inclined manner. The inclined surface of the photovoltaic panel 5 is the energy absorbing surface of the sunlight, which can absorb a large amount of sunlight and improve the conversion efficiency of electrical energy. In addition, when strong wind weather comes and strong wind attacks the photovoltaic panel 5, if the strong wind level is very high, the photovoltaic panel 5 will push the carrier 4 to move, and the carrier 4 will move the top frame 3, and the top frame 3 will move the gear 6. At the same time, the slide plate 12 will also move and slide along the guide rod 11, and will also squeeze the support spring 13, so that the support spring 13 is compressed and shortened. When the gear 6 moves to contact with the rack 7, the gear 6 will be engaged and rotated by the rack 7. At this time, the gear 6 will also deflect downward with the carrier 4, and the carrier 4 will deflect downward with the photovoltaic panel 5, so that the photovoltaic panel 5 is lowered from its original height position. Since the height position of the photovoltaic panel 5 is lowered by deflecting downward at this time, it is equivalent to that the windward side of the photovoltaic panel 5 is less affected by the strong wind, and the destructive force suffered is reduced. At this time, the photovoltaic panel 5 achieves the purpose of automatic unloading. However, when the wind intensity is degraded, the intensity of wind attack on the photovoltaic panel 5 will also decrease. At this time, the force provided by the photovoltaic panel 5 to the carrier 4 will also become smaller, and the thrust provided by the carrier 4 to the top frame 3 will also decrease. The pressure of the slide plate 12 on the support spring 13 will also decrease. At this time, the support spring 13 will release its length and provide a reverse thrust to the slide plate 12 while releasing its length, forcing the slide plate 12 to move in the opposite direction with the top frame 3, and the top frame 3 will bring the carrier 4 to reset in the opposite direction. While the carrier 4 brings the gear 6 to reset in the opposite direction, the gear 6 meshes with the rack 7 and rotates in the opposite direction. Under the reverse action of the gear 6, the carrier 4 is deflected upward again, and the carrier 4 rotates the photovoltaic panel 5 upward to the angle to receive light exposure. Of course, as the wind level changes, the degree of movement of the top frame 3 is not completely fixed. It only means that when the wind is strong, the top frame 3 will move to unload the load of the carrier 4 with the photovoltaic panel 5. When the wind is stronger, the degree of movement of the top frame 3 will be greater, so that the carrier 4 can unload the load of the photovoltaic panel 5, and it is possible to move the gear 6 to continuously mesh with the rack 7 and complete the downward deflection, further improving the unloading effect. In any case, the photovoltaic panel 5 can achieve automatic unloading protection when it is hit by strong winds.

[0031] like Figure 8 , Fig. 9As shown, when the degree of downward deflection of the carrier 4 is so great that its bottom surface falls on the strut 8, if there is still strong wind, the two parts of the carrier 4 will deflect downward at the hinged position, mainly the proximal part falls on the strut 8, and the distal part is supported by the strut 8 and deflects downward with the hinged position as the rotation point, while the photovoltaic panel 5 continues to deflect downward, further reducing the angle of the windward surface of the photovoltaic panel 5 to meet the strong wind, so that the effect of automatic unloading protection of the photovoltaic panel 5 when it is attacked by strong wind is further improved. Of course, in actual assembly, the two hinged parts of the carrier 4 are hinged together through a hinge shaft, and a torsion spring is used to connect the hinge shaft and the two parts of the carrier 4. After the wind strength is reduced, the torsion spring provides a rotation force to the two parts of the carrier 4, so that the two parts of the carrier 4 rotate around the hinge shaft to restore. This assembly principle of the torsion spring and the hinge shaft is a prior art. The present invention only describes that the carrier 4 is hinged in two parts, which includes this technical definition. Since it is a prior art, it is no longer shown in the figure.

[0032] Since there are two photovoltaic panels 5 and these two photovoltaic panels 5 are installed on two parts of the carrier 4, when the carrier 4 deflects onto the support rod 8, the distal part will also deflect downward with the distal photovoltaic panel 5, so that the photovoltaic panel 5 can achieve the purpose of further unloading force and automatic protection. Moreover, when the distal photovoltaic panel 5 deflects downward, it is equivalent to forming a gap between this photovoltaic panel 5 and the proximal photovoltaic panel 5 at the hinge position, which is conducive to leakage through the gap when strong wind blows onto the photovoltaic surface.

[0033] like Figure 1 , Figure 7 As shown, a first limiting tube 9 is welded to one end of the top surface of the base frame 1, and a second limiting tube 10 is welded to the other end of the top surface of the base frame 1. The gear 6 is on the same side as the first limiting tube 9, and a rubber rod 21 is fixed to the same side end of the top frame 3 and the gear 6. The rubber rod 21 extends perpendicularly to the direction of the first limiting tube 9 and exceeds the gear 6. The two limiting tubes are located at both ends of the top frame 3 to limit the back and forth movement of the top frame 3 to prevent the top frame 3 from falling off. When the top frame 3 returns to one side of the first limiting tube 9, one end of the rubber rod 21 is used to push against the first limiting tube 9 to achieve flexible buffering, while preventing the gear 6 from directly hitting the first limiting tube 9, thereby limiting the travel of the gear 6 and protecting the gear 6.

[0034] like Figure 3 , Figure 5 As shown, in order to prevent strong winds from invading the photovoltaic panels 5, the carrier 4, driven by the top frame 3, can move smoothly along the bottom frame 1 to avoid jamming during movement. Therefore, a pulley 14 is installed on the top frame 3. There are several pulleys 14, which are equidistantly arranged along the length direction of the top frame 3, and the pulleys 14 are slidably fitted in the guide rails 2 on the bottom frame 1.

[0035] like Figure 2 , Figure 5 As shown, a rotating sleeve 15 is welded on the bottom surface of the carrier 4, and the rotating sleeve 15 is close to one end on which the gear 6 is installed. A rotating arm 16 is installed on the rotating sleeve 15, and a pin 17 is welded on the top frame 3, and the pin 17 is located between the gear 6 and the rotating sleeve 15. The other end of the rotating arm 16 is tilted downward and then transferred to the pin 17. A pulling plate 18 is welded on the carrier 4 and the rotating arm 16, and a tension spring 19 is connected between the two pulling plates 18. Under the pulling action of the pulling plate 18 on the carrier 4, the tension spring 19 provides a pulling force to the rotating arm 16, so as to deflect and pull up the end of the rotating arm 16 transferred to the rotating sleeve 15, and the carrier 4 is pulled up to the deflected upward position by the end of the rotating arm 16 transferred to the rotating sleeve 15. When the carrier 4 deflects downward, the rotating arm 16 is pushed to deflect downward through the rotating sleeve 15. At this time, the tension spring 19 is stretched downward and lengthened, and the carrier 4 moves back to its original position in the opposite direction. When the gear 6 leaves the rack 7, the tension spring 19 rebounds and shortens and provides elastic tension to the bottom end of the rotating arm 16 to pull the rotating arm 16 to rotate upward. The rotating arm 16 drives the top rotating sleeve 15 to rotate upward, and the rotating sleeve 15 drives the carrier 4 to rotate upward. The carrier 4 rotates upward with the photovoltaic panel 5 to an inclined angle, so that the photovoltaic panel 5 uses the inclined photovoltaic surface to absorb light over a large area again.

[0036] In order to make the above functions symmetrical on the carrier 4, to improve the stability of the carrier 4 when it moves and to enhance its supporting effect, Figures 1 to 9 As shown, there are two bottom frames 1, which are symmetrically arranged on both sides of the carrier 4, and there are two top frames 3. A row of pulleys 14 are installed on the two top frames 3, and they slide on the two bottom frames 1 respectively through the pulleys 14. Tension springs 19 are installed on the two top frames 3 in the same way, and the other ends of the two tension springs 19 are transferred to the carrier 4 in the same connection manner. A rack 7 is installed on at least one of the bottom frames 1, and a gear 6 is installed on at least one side of the carrier 4. When one gear 6 is moved to the rack 7 and meshed and rotated, the carrier 4 can be deflected downward with the photovoltaic panel 5 to reduce the height, and there is no need to set the gear 6 and the rack 7 into two sets.

[0037] The present invention also provides a photovoltaic device, which is suitable for the photovoltaic panel bracket as described above, including an electrical box (or a distribution cabinet) fixed on the base frame 1, a circuit (wire) connected in series between two photovoltaic panels 5, at least an energy storage unit and an energy conversion unit are provided in the electrical box, and the output end of the circuit is connected to the energy storage unit and the energy conversion unit in the electrical box. Although the two photovoltaic panels 5 are separately arranged on two parts of the carrier 4, the carrier 4 falls on the support rod 8, as shown in the figure. Fig. 9As shown, when the distal end of the carrier 4 is deflected downward again at the hinged position, this part of the carrier 4 will also deflect downward with the distal photovoltaic panel 5. In addition to causing a gap between this photovoltaic panel 5 and the other photovoltaic panel 5 at the hinged position, the circuit connected in series between the two photovoltaic panels 5 will also move flexibly without causing the wires to be torn or broken.

[0038] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0039] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention.
