Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and specifically relates to a photovoltaic power station bracket that is easy to adjust. Background Art

[0002] A photovoltaic power station is a power generation system that uses solar energy, adopts photovoltaic panel components, inverters and some other electronic components installed on a bracket, is connected to the power grid and transmits electricity to the power grid.

[0003] Photovoltaic panel components need to be installed outdoors. When encountering special weather, such as hail, heavy rain and strong wind weather, since photovoltaic panel components are generally made of high-efficiency materials such as monocrystalline silicon or polycrystalline silicon, the monocrystalline silicon material itself has high brittleness and is easy to break when subjected to external forces. When the light-receiving surface of the photovoltaic panel component is in hail or heavy rain weather, the surface is easily damaged by the impact force of hail or raindrops, resulting in a shortened service life of the photovoltaic component, and further affecting the power generation efficiency of the photovoltaic power station. In strong wind weather, when the strong wind passes through the photovoltaic panel component and the resistance generated is too large, the bracket will be deformed in the long term, resulting in the photovoltaic panel component losing support and affecting the normal photovoltaic power generation work of the subsequent photovoltaic panel component.

Detailed implementation manners

[0043] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0044] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a photovoltaic power station bracket that is easy to adjust includes a base 6. The upper surface of the base 6 is rotatably connected to a support frame 4. Two auxiliary pieces 1 that are symmetric left and right are fixedly connected to the front surface of the base 6. A photovoltaic panel assembly 9 is hinged to the support frame 4. A plurality of arc-shaped limiting grooves arranged in a circumferential array are formed on the upper surface of the base 6. Limiting columns are fixedly connected to the lower surface of the support frame 4 at positions corresponding to the arc-shaped limiting grooves. The limiting columns slide inside the arc-shaped limiting grooves to limit the rotation angle of the support frame 4 on the base 6. The photovoltaic power station bracket further includes a protection mechanism 7 for protecting the light-receiving surface of the photovoltaic panel assembly 9 from damage in special weather. The protection mechanism 7 is arranged at the top of the photovoltaic panel assembly 9. The photovoltaic power station bracket further includes a pressing mechanism 8 for assisting the protection mechanism 7 to protect the light-receiving surface of the photovoltaic panel assembly 9. The number of the pressing mechanisms 8 is two and they are symmetrically arranged left and right on the photovoltaic panel assembly 9. The photovoltaic power station bracket further includes a transmission mechanism 3 for driving the protection mechanism 7 to open and close for protection. The transmission mechanism 3 is arranged on the support frame 4. The photovoltaic power station bracket further includes a pushing mechanism 5 for driving the support frame 4 to rotate on the base 6. The pushing mechanism 5 is arranged on the support frame 4.

[0045] As Figure 5 shown, the transmission mechanism 3 includes two symmetrically arranged left and right winches 32 arranged on the upper surface of the support frame 4. First transmission disks 34 are rotatably connected to the opposite surfaces of the two winches 32. A gear shaft 35 is rotatably connected to the upper surface of the support frame 4. The right side of the gear shaft 35 is slidably connected to a universal coupling 33 through a spline shaft. A transmission member 31 is arranged on the upper surface of the support frame 4 and behind the gear shaft 35. The gear shafts 35 between two adjacent support frames 4 are linked through the universal coupling 33.

[0046] As Figure 5As shown in the figure, the pushing mechanism 5 includes a first elastic telescopic connecting rod 52 hinged to the rear end of the right surface of the support frame 4. The rear end of the first elastic telescopic connecting rod 52 is hinged with a linkage rod 51. Connecting card slots are provided at both the left and right ends of the linkage rod 51. Connecting plug rods 53 are clamped in the internal of the connecting card slots through limit bolts. The linkage rods 51 between two adjacent support frames 4 are linked through the connecting plug rods 53.

[0047] A driving motor and a hydraulic telescopic rod are arranged at the rightmost end of the whole row of support frames 4. The right end of the universal coupling 33 on the rightmost support frame 4 is slidably connected with the output shaft of the driving motor through a spline shaft. The right end of the connecting plug rod 53 on the rightmost support frame 4 is fixedly connected with the telescopic end of the hydraulic telescopic rod.

[0048] During specific use, when encountering special weather, first, the driving motor drives the gear shaft 35 to rotate on the support frame 4 through the universal coupling 33. At the same time, the hydraulic telescopic rod pushes the linkage rod 51 to move leftward through the connecting plug rod 53. At this time, the linkage rod 51 drives the support frame 4 to deflect on the base 6 through the first elastic telescopic connecting rod 52. The limiting column on the support frame 4 cooperates with the arc-shaped limiting groove on the base 6 to limit the deflection angle of the support frame 4. At the same time, after the limiting column at the upper end of the support frame 4 is pushed from one end to the other end in the arc-shaped limiting groove through the linkage rod 51, the deflection angle of the support frame 4 reaches the maximum. At the same time, the linkage rod 51 maintains the thrust on the support frame 4, so that while the support frame 4 remains stationary in the deflected position on the base 6, the cooperation with the limit of the arc-shaped limiting groove can make the support frame 4 more stable.

[0049] It should be noted that multiple support frames 4 are linked through the connecting plug rods 53. After connecting connecting plug rods 53 with appropriate lengths between the linkage rods 51 on two adjacent support frames 4 and locking them with limit bolts, the support frames 4 on multiple bases 6 can be deflected synchronously. At the same time, the connection between the gear shafts 35 on two adjacent support frames 4 through the universal coupling 33 can realize the linkage between the gear shafts 35 on two adjacent support frames 4. And through the spline fit between the universal coupling 33 and the gear shaft 35, the linkage of the gear shafts 35 on two adjacent support frames 4 is maintained during the deflection of the support frame 4 on the base 6, so that the photovoltaic panel assembly 9 can change from an inclined state to a vertical state on the support frame 4 and the rubber protection pad 72 can cover the photovoltaic panel assembly 9 synchronously.

[0050] As Figure 6 shown, the state adjustment mechanism 2 includes two symmetrically arranged placement grooves 21 opened on the upper surface of the support frame 4. An adjusting member 22 is jointly arranged inside the two placement grooves 21.

[0051] As Figure 6 and Figure 7As shown, the adjusting member 22 includes a toothed plate 221 slidably connected inside the placement groove 21. A pull rod 223 is hinged to the front end of the toothed plate 221. The tops of the two pull rods 223 are jointly hinged to a hinge seat 222. The hinge seat 222 is hinged to the bottom end of the photovoltaic panel assembly 9. A plurality of connecting rollers 224 are rotatably connected to the lower surface of the toothed plate 221. The connecting rollers 224 are slidably connected to the inner wall of the bottom end of the placement groove 21. The gears at both ends of the gear shaft 35 are respectively engaged with the left and right toothed plates 221.

[0052] During specific use, when the gear shaft 35 rotates on the support frame 4, the gear shaft 35 drives the toothed plate 221 to slide backward inside the placement groove 21 through the gears on it. The cooperation of the connecting rollers 224 on the lower surface of the toothed plate 221 can make the toothed plate 221 slide more smoothly inside the placement groove 21. When the toothed plate 221 slides backward inside the placement groove 21, the toothed plate 221 drives the photovoltaic panel assembly 9 to rotate on the support frame 4 through the pull rod 223 and the hinge seat 222. At this time, the photovoltaic panel assembly 9 gradually changes from an inclined state to a vertical state until the photovoltaic panel assembly 9 is pulled to the vertical state. At this time, the rotation of the gear shaft 35 is stopped, so that the photovoltaic panel assembly 9 maintains the vertical state.

[0053] As Figure 8 shown, the transmission member 31 includes a U-shaped mounting frame 312 fixedly connected to the support frame 4. A connecting shaft 311 is rotatably connected between the two vertical sections of the U-shaped mounting frame 312. Second transmission discs 313 are fixedly connected to both the left and right ends of the connecting shaft 311. The gear shaft 35 is connected to the connecting shaft 311 through a belt drive. The second transmission disc 313 is also connected to the first transmission disc 34 through a belt drive.

[0054] As Figure 9 shown, the protection mechanism 7 includes a winding member 71 provided on the photovoltaic panel assembly 9. A rubber protection pad 72 for protecting the light-receiving surface of the photovoltaic panel assembly 9 is provided on the winding member 71.

[0055] As Figure 9 and Figure 10 shown, the winding member 71 includes a fixed shell 714 fixedly connected to the top end of the photovoltaic panel assembly 9. A left-right arranged winding drum 711 is rotatably connected inside the fixed shell 714. A volute spring (not shown in the figure) is provided between the winding drum 711 and the fixed shell 714. A rubber protection pad 72 is wound around the winding drum 711. One end of the rubber protection pad 72 away from the winding drum 711 penetrates to the outside of the fixed shell 714. A support frame 712 is fixedly installed at the middle position of the outer surface of the upper side of the fixed shell 714 perpendicular to the photovoltaic panel assembly 9. The rubber protection pad 72 bypasses the top end of the support frame 712. An L-shaped protection shell 713 for preventing rainwater from entering the inside of the fixed shell 714 is fixedly connected to the upper side of the fixed shell 714.

[0056] AsFigure 11 and Figure 12 As shown in Figure 12 , taking the pressing mechanism 8 on the right side as an example, the pressing mechanism 8 includes a plurality of support blocks 82 fixedly connected to the right side of the photovoltaic panel assembly 9. A mounting shell 81 is fixedly connected to the plurality of support blocks 82. The left side and the upper side of the mounting shell 81 are both open. An extrusion member 83 for pressing the rubber protection pad 72 is provided on the mounting shell 81, and a pulling member 84 for driving the extrusion member 83 to press the rubber protection pad 72 is provided on the mounting shell 81.

[0057] As Figure 12 and Figure 13 As shown in Figure 13 , the pulling member 84 includes a connecting slider 843 slidably connected to the upper surface of the mounting shell 81. A connecting chute adapted to the connecting slider 843 is provided on the upper surface of the mounting shell 81. A pulling rope 842 is fixedly connected to the connecting slider 843. A wire guiding pulley seat 841 is fixedly installed at the front end of the mounting shell 81.

[0058] As Figure 10 , Figure 12 and Figure 13 As shown in Figure 13 , the bottom end of the connecting slider 843 is slidably connected to the connecting chute and penetrates into the interior of the mounting shell 81 and is fixedly connected to one end of the rubber protection pad 72 away from the winding drum 711. Through the arrangement of the two connecting sliders 843, the left and right ends of the rubber protection pad 72 away from the winding drum 711 can be always kept tightened. One end of the pulling rope 842 away from the connecting slider 843 bypasses the wire guiding pulley seat 841 and is fixedly connected to the winch 32. The winch 32 winds the pulling rope 842 thereon.

[0059] During specific use, when the gear shaft 35 rotates on the support frame 4, the connecting shaft 311 is driven to rotate on the U-shaped mounting bracket 312 through the belt. The U-shaped mounting bracket 312 drives the first transmission disc 34 to rotate on the winch 32 through the second transmission disc 313, so that the winch 32 performs a winding action on the pulling rope 842. Through the winding of the pulling rope 842, the connecting slider 843 is pulled to slide downward on the mounting shell 81. The pulling rope 842 pulls the rubber protection pad 72 to move synchronously. The rubber protection pad 72 is pulled out from the interior of the fixed shell 714 under the tension, and at the same time drives the winding drum 711 to rotate inside the fixed shell 714. At this time, the scroll spring between the winding drum 711 and the fixed shell 714 contracts.

[0060] The provision of the support frame 712 can prevent rainwater and sundries from entering the interior of the fixed shell 714, which may affect the normal retraction and extension of the rubber protection pad 72. The rubber protection pad 72 passes through the support frame 712 and slides inside the installation shell 81, which can create a certain gap between the rubber protection pad 72 and the light-receiving surface of the photovoltaic panel assembly 9 after the light-receiving surface of the photovoltaic panel assembly 9 is blocked. When hail or rain hits the rubber protection pad 72, the impact force will not act on the light-receiving surface of the photovoltaic panel assembly 9, thereby protecting the light-receiving surface of the photovoltaic panel assembly 9.

[0061] It should be noted that since the diameter of the second transmission disk 313 is larger than that of the first transmission disk 34, the length of the winch 32 winding the pulling rope 842 driven by the second transmission disk 313 through the first transmission disk 34 is greater than the distance that the gear shaft 35 drives the tooth plate 221 to slide inside the placement groove 21. At the same time, both the upper and lower ends of the installation shell 81 exceed the upper and lower ends of the photovoltaic panel assembly 9, and there is a certain margin after the rubber protection pad 72 covers the light-receiving surface of the photovoltaic panel assembly 9. Therefore, during the process of the photovoltaic panel assembly 9 changing from different inclined states to the vertical state, the light-receiving surface of the photovoltaic panel assembly 9 can be completely blocked and protected.

[0062] As Figure 14 、 Figure 15 、 Figure 16 and Figure 17 shown, the extrusion member 83 includes a plurality of second elastic telescopic connecting rods 833 fixedly connected to the inner wall of the bottom end of the installation shell 81. The tops of the plurality of second elastic telescopic connecting rods 833 are commonly fixedly connected with an extrusion plate 832. An elastic sliding connection is provided on the inner wall of the bottom end of the installation shell 81 with a push plate 835. The bottom end of the push plate 835 penetrates to the outside of the installation shell 81 and is fixedly connected with a connecting ball 836. A plurality of evenly distributed protection rollers 831 for protecting the edge of the rubber protection pad 72 are rotatably connected to the inner wall on the right side of the installation shell 81. Adaptation grooves 834 are provided at corresponding positions of the push plate 835 for the second elastic telescopic connecting rods 833. The push plate 835 is slidably connected with the second elastic telescopic connecting rods 833. A plurality of first protrusions are evenly arranged on the lower surface of the extrusion plate 832. A plurality of second protrusions are arranged on the upper surface of the push plate 835. Both the second protrusions and the first protrusions are arc-shaped protrusions. The plurality of first protrusions and the plurality of second protrusions correspond one by one and are located behind the second protrusions.

[0063] During specific use, when the photovoltaic panel assembly 9 changes from an inclined state to a vertical state, the mounting shell 81 moves synchronously with the photovoltaic panel assembly 9. At this time, the connecting ball 836 gradually becomes vertical as the mounting shell 81 gradually approaches the auxiliary sheet 1. When the connecting ball 836 contacts the auxiliary sheet 1, as the photovoltaic panel assembly 9 continues to move, the connecting ball 836 gradually conflicts with the auxiliary sheet 1. As the photovoltaic panel assembly 9 continues to rotate, the auxiliary sheet 1 gradually gives the connecting ball 836 a reverse thrust, causing the connecting ball 836 to move toward the upper end of the mounting shell 81, that is, the connecting ball 836 rotates with the photovoltaic panel assembly 9. The mounting shell 81 slides relative to the length direction. At this time, the second protrusion on the pushing plate 835 slides against the arc surface of the first protrusion on the extrusion plate 832, pushing the extrusion plate 832 upward. At this time, the second elastic telescopic connecting rod 833 extends, and the edge of the rubber protection pad 72 inside the mounting shell 81 is pressed tightly inside the mounting shell 81 through the extrusion plate 832. At this time, the rubber protection pad 72 is clamped between the extrusion plate 832 and the mounting shell 81, so that after the rubber protection pad 72 is subjected to impact force, it has sufficient supporting force to offset the impact force, thereby protecting the light-receiving surface of the photovoltaic panel assembly 9.

[0064] When the photovoltaic panel assembly 9 moves to a vertical state, the rubber protective pad 72 completely covers the light-receiving surface of the photovoltaic panel assembly 9, and the left and right ends are clamped inside the mounting shell 81. At the same time, the support frame 4 is deflected on the base 6, and the photovoltaic panel assembly 9 becomes a vertically deflected state (such as Figure 16 As shown), and by setting the protective roller 831, the sliding friction between the edge of the rubber protective pad 72 and the mounting shell 81 is converted into rolling friction, which can reduce the friction damage to the edge of the rubber protective pad 72 when the rubber protective pad 72 covers the photovoltaic panel assembly 9.

[0065] When the photovoltaic panel assembly 9 needs to be restored to its original position, the driving motor is reversed to drive the gear shaft 35 to reverse, and the gear shaft 35 pushes the tooth plate 221 to restore to its original position inside the placement groove 21, and the photovoltaic panel assembly 9 is pushed from the vertical state to the inclined state through the hinge seat 222 and the pull rod 223. At the same time, the gear shaft 35 drives the winch 32 to unwind through the transmission member 31. At this time, the pull rope 842 no longer generates tension on the rubber protective pad 72, and the connecting ball 836 is separated from the auxiliary plate 1. Since the push plate 835 is elastically slidably connected to the mounting shell 81, the push plate 835 is restored to its original position under the action of the elastic force, and the push plate 835 no longer generates thrust on the extrusion plate 832.

[0066] Under the action of the self-elastic force of the second elastic telescopic connecting rod 833, the pressing plate 832 is restored to its original position. At this time, the rubber protection pad 72 is no longer subjected to the clamping force inside the installation shell 81. Under the action of the elastic force of the scroll spring between the winding drum 711 and the fixed shell 714, the rubber protection pad 72 is retracted into the fixed shell 714 and wound around the winding drum 711. At the same time, by contracting the hydraulic telescopic rod, the support frame 4 is restored to its original position on the base 6. At this time, the photovoltaic panel assembly 9 can carry out normal solar power generation work.

[0067] It should be noted that according to needs, a cleaning sponge unit can be clamped between one end of the rubber protection pad 72 connected to the connecting slider 843 and located between the two installation shells 81 (as Figure 17 shown). When the rubber protection pad 72 is retracted on the photovoltaic panel assembly 9, it can drive the cleaning sponge unit to slide along the light-receiving surface of the photovoltaic panel assembly 9, so as to clean the water stains and dust on the light-receiving surface of the photovoltaic panel assembly 9, so that the light-receiving surface of the photovoltaic panel assembly 9 can absorb sunlight more efficiently.

[0068] Working principle: When in use, in the face of special weather conditions such as sandstorms, hailstorms or heavy rains, first, the driving motor drives the gear shaft 35 to rotate on the support frame 4 through the universal coupling 33. The gear shaft 35 drives the first transmission disk 34 to rotate through the transmission member 31, so that the winch 32 winds up the pull rope 842. The connecting slider 843 is pulled by the pull rope 842 to slide on the installation shell 81, and the rubber protection pad 72 is gradually covered on the light-receiving surface of the photovoltaic panel assembly 9. At the same time, the gear shaft 35 drives the toothed plate 221 to slide inside the placement groove 21, and drives the photovoltaic panel assembly 9 to rotate on the support frame 4 through the hinge seat 222, and pulls the inclined photovoltaic panel assembly 9 to the vertical state.

[0069] After the photovoltaic panel assembly 9 becomes vertical, at this time, the rubber protection pad 72 also completely blocks the light-receiving surface of the photovoltaic panel assembly 9. At the same time, the left and right ends of the rubber protection pad 72 are pressed tightly inside the installation shell 81 through the pressing member 83, so that the rubber protection pad 72 maintains a propped state, and there is a certain distance between the rubber protection pad 72 and the light-receiving surface of the photovoltaic panel assembly 9, so as to realize the protection of the light-receiving surface of the photovoltaic panel assembly 9. When the photovoltaic panel assembly 9 changes from the inclined state to the vertical state, the hydraulic telescopic rod drives the support frame 4 to rotate on the base 6 through the pushing mechanism 5, and deflects the vertical photovoltaic panel assembly 9 by a certain angle, so as to reduce the impact force generated by the strong wind on the photovoltaic panel assembly 9.
