Description

Technical Field

[0001] The present invention relates to the technical field of distributed photovoltaic modules, and in particular to a distributed rooftop photovoltaic module power generation system. Background Art

[0002] A distributed photovoltaic power generation system is a system that uses solar photovoltaic technology to convert solar energy into electrical energy. Its characteristic is that the solar power generation system is distributed in different geographical locations or buildings instead of being concentrated in a single large power station.

[0003] This system usually includes solar photovoltaic modules, inverters, battery energy storage systems, power management systems and other components. Among them, solar photovoltaic modules are essential components of photovoltaic power generation systems. Usually, multiple solar photovoltaic modules are arranged in multiple rows and fixed on the roof of a building. Solar photovoltaic modules include solar panels and support frames. The support frames usually include four support legs. In order to make the support stable, during installation, cement piers are usually built on the roof of the building, and the bottom of the support legs are poured into the cement piers. The solar panels are fixed to the top of the support legs through purlins or other connectors. Since the direction of sunlight changes continuously during the day, people have begun to study some support frames that can adjust the support angle or direction of solar panels so that the solar panels can fully receive sunlight and increase power generation. However, there are still many defects in the adjustable solar panel support frames in the prior art, such as:

[0004] 1. A common adjustable solar panel support frame in the prior art includes a U-shaped frame and a rotating shaft. The bottom of the U-shaped frame is fixed on the roof of the building, and the solar panel is located in the opening of the U-shaped frame. The rotating shaft is fixed in the middle of the solar panel, and both ends are rotatably connected to the side walls of the U-shaped frame opening. A driving motor is arranged on one side of the U-shaped frame, and photoresistors are arranged on two opposite sides of the solar panel. The resistance of the photoresistors reflects the angle of sunlight exposure, and then the driving motor is controlled to drive the rotating shaft and the solar panel to rotate so that the resistance values ​​of the two photoresistors are the same, so as to achieve the purpose of making sunlight directly shine on the solar panel. However, it can only adjust its vertical support angle, but not the direction of the solar panel. Compared with the traditional support frame, it only supports the middle part of the solar panel, and the support stability is poor.

[0005] 2. In the prior art, a small number of adjustable solar panel support frames can be seen that can adjust both the vertical angle and the direction of the solar panel. A base is added to the structure of the above-mentioned support frame, and the base is fixed at the bottom of the U-shaped frame. A drive motor is arranged on the roof of the building to drive the base to rotate horizontally. Photoresistors are arranged on the other two sides of the solar panel to control the action of the drive motor. Although the angle and direction of the solar panel can be adjusted, the rows of photovoltaic modules cannot be linked. Each photovoltaic module needs to be equipped with two drive motors, which greatly increases the cost. In the process of the photovoltaic module rotating in the direction, the wires connected to the drive motors arranged on the U-shaped frame will be bent repeatedly, which can easily cause the insulating surface on it to crack, resulting in electrical disconnection. Summary of the invention

[0006] 1. Technical Problems Solved

[0007] The technical problem to be solved by the present invention is to overcome the problems in the prior art that the support frame adjustment cannot meet the usage requirements, the support is unstable and the cost is high, and to provide a distributed rooftop photovoltaic component power generation system that can realize both the angle adjustment of the solar panel and the direction adjustment, and can link the entire row of photovoltaic components.

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below in conjunction with the embodiments.

[0040] Combined with Figure 1 , 2 9. A distributed rooftop photovoltaic assembly power generation system comprises a plurality of photovoltaic assemblies 1 arranged in a row, the photovoltaic assembly 1 comprises a solar panel 2 and four supporting legs 3, wherein two supporting legs 3 are located in front of the solar panel 2, and are called front supporting legs, and two supporting legs 3 are located in the rear of the solar panel 2, and are called rear supporting legs, the supporting legs 3 comprise a sleeve 4 and a telescopic rod 5 slidably arranged in the sleeve 4, the solar panel 2 is movably connected to the telescopic rod 5, and further comprises a base 6 and a supporting plate 7 rotatably arranged on the base 6, the sleeve 4 is fixedly arranged on the supporting plate 7, a cross beam 8 is arranged between two adjacent sleeves 4, a rotating cross bar 9 is arranged between the two cross beams 8, a rotating vertical rod 10 is arranged in the base 6, which passes through the supporting plate 7 and is rotatably connected to the supporting plate 7, and the rotating cross bar 9 is connected to the rotating vertical rod 10. 10 is provided with a transmission bevel gear set that cooperates with each other; a transmission component 11 is provided in the crossbeam 8, and the power of the rotating cross bar 9 is transmitted to the telescopic rod 5 through the transmission component 11 to make it rise and fall; a driving component 12 for driving the support plate 7 to rotate and a driving component 2 13 for driving the rotating vertical rod 10 to rotate are provided in the base 6, and a linkage component 14 is provided between the driving component 12 and the driving component 2 13, which can simultaneously drive the rotating vertical rod 10 to rotate when the support plate 7 rotates; a linkage component 2 15 is provided between two adjacent bases 6 in the same row for connecting the corresponding two driving components 12 or two corresponding driving components 2 13, and two driving motors 16 are provided on the roof of the building, which are respectively connected to the driving component 12 and the driving component 2 13 on the head end photovoltaic component 1 in the same row.

[0041] Through the above structure, when adjusting the direction of the solar panel, the drive motor 16 corresponding to the drive component 12 is started, and the drive component 12 drives the support plate 7 to rotate. At the same time, through the linkage component 14, the rotation of the support plate 7 also drives the rotating vertical rod 10 to rotate, thereby avoiding affecting the support angle of the solar panel 2 when adjusting the direction of the solar panel 2; when adjusting the support angle of the solar panel, the drive motor 16 corresponding to the drive component 2 13 is started, driving the rotating vertical rod 10, and through the transmission of the bevel gear set 1, the rotating cross rod 9 is rotated, and the support leg 3 is driven to extend and retract through the transmission component 11, thereby rotating the solar panel 2 vertically.

[0042] Combined with Figure 2 , 910. Connectors are provided at the four corners of the bottom of the solar panel 2 for connecting the supporting legs 3 and the solar panel. The connectors include a connector 1 50 and a connector 2 51. The connector 1 50 corresponds to the front supporting leg, and the connector 2 51 corresponds to the rear supporting leg. A hinge shaft 52 is provided on the top side wall of the telescopic rod 5. The connector 1 50 is provided with a hinge hole 53, and the corresponding hinge shaft 52 is rotatably arranged therein. The connector 2 51 is provided with a strip hole 54, and the corresponding hinge shaft 52 is rotatably and slidably arranged therein.

[0043] Through the above structure, when the solar panel 2 rotates, it rotates around the hinge shaft 52 corresponding to the connecting piece 50 as the axis. By making the hinge shaft 52 on the rear supporting leg cooperate with the strip hole 54, a margin is reserved for the corresponding hinge shaft 52 here to prevent the rear supporting leg 3 from being pulled and deformed when the solar panel 2 rotates.

[0044] Combined with Figure 2 The bevel gear set includes two bevel gears, one of which is fixedly arranged on the top of the rotating vertical rod 10, and the other bevel gear is meshed with the bevel gear and fixedly connected to the rotating cross rod 9.

[0045] Through the above structure, the power transmission between the rotating vertical rod 10 and the rotating horizontal rod 9 is realized, and the angle adjustment of the solar panel 2 is achieved.

[0046] Combined with Figure 3 , 4 The driving component 12 includes a rotating sleeve 17, a worm gear 18 and a worm 19. The rotating sleeve 17 is fixedly connected to the support plate 7. The worm gear 18 is fixedly arranged on the rotating sleeve 17 and meshes with the worm 19. The driven component 2 13 includes a coaxially arranged bevel gear 1 20, a worm gear 21 and a worm 22 meshing with the worm gear 21. A bevel gear 23 is provided at the bottom of the rotating vertical rod 10. The bevel gear 1 20 and the bevel gear 23 are located on the same axis, and a bevel gear 3 24 is provided between the two. The linkage component 14 includes a rotating ring 25 and a linkage gear set 26 for driving the rotating ring 25 to rotate synchronously when rotating. A horizontal shaft 49 for supporting the bevel gear 3 24 is provided in the rotating ring 25, and the bevel gear 3 24 is rotatably arranged on the horizontal shaft 49.

[0047] The output shafts of the two driving motors 16 are connected to the worm 1 19 and the worm 2 22 respectively through the linkage assembly 1 14 .

[0048] The linkage gear set includes two coaxially arranged linkage gears 27 and a gear ring 1 28 and a gear ring 29 respectively meshing with the two linkage gears 27 . The gear ring 1 28 is fixedly sleeved on the rotating sleeve 17 , and the gear ring 29 is fixedly sleeved on the outer side of the rotating ring 25 .

[0049] Through the above structure, when adjusting the direction of the solar panel 2, the corresponding driving motor 16 drives the worm 19 to rotate, and drives the rotating sleeve 17 and the support plate 7 fixed thereon to rotate through the worm gear 18, thereby driving the solar panel 2 to rotate on the horizontal plane, so that its direction changes; when the solar panel 2 rotates on the horizontal plane, the bevel gear on the rotating cross bar 9 will rotate around the bevel gear on the top of the rotating vertical rod 10; during the rotation of the rotating sleeve 17, the gear ring 1 28 drives the interlocking gear 27 meshing with it to rotate, and transmits power to the gear ring 2 29 through another interlocking gear 27, so that the rotating ring 25 rotates. During the rotation of the rotating ring 25, the bevel gear three 24 is driven to rotate around the bevel gear one 20. Since another driving motor 16 prevents the worm gear two 22 from rotating, the worm gear two 21 and the bevel gear one 20 are stationary. Therefore, during the rotation of the bevel gear three 24 around the bevel gear one 20, the bevel gear three 24 meshes with the bevel gear one 20 and also rotates, thereby driving the bevel gear two 23 to rotate, and the rotating vertical rod 10 rotates, so that the support plate 7 and the rotating vertical rod 10 rotate synchronously, and the bevel gear on the top of the rotating vertical rod 10 and the bevel gear on the rotating cross rod 9 are relatively stationary, thereby avoiding affecting the support angle of the solar panel 2 when the direction is adjusted.

[0050] When adjusting the support angle of the solar panel 2, the corresponding drive motor 16 drives the worm gear 22 to rotate, and drives the bevel gear 1 20 to rotate. At the same time, another drive motor 16 prevents the worm gear 19 from rotating, so that the rotating sleeve 17 is stationary, and the rotating ring 25 is prevented from rotating through the gear ring 1 28, the linkage gear 27, and the gear ring 29. Under the condition that the rotating ring 25 is stationary, the bevel gear 1 20 rotates to drive the bevel gear 3 24 to rotate around the horizontal axis 49, thereby driving the bevel gear 2 23 to rotate, and the rotating vertical rod 10 rotates. Since the rotating sleeve 17 is stationary and the support plate 7 is stationary, the bevel gear on the top of the rotating vertical rod 10 engages with the bevel gear on the rotating cross bar 9, so that the rotating cross bar 9 rotates, and then the front and rear support legs are extended and retracted through the transmission of the transmission assembly 11 to achieve the angle adjustment of the solar panel 2.

[0051] Combined with Figure 3 , 4 A bracket 55 for supporting the rotating ring 25 is provided in the base 6 , and the rotating ring 25 is rotatably arranged on the bracket 55 .

[0052] The above structure plays a certain fixing role on the rotating ring 25, so that it can only rotate around its axis, avoiding its displacement causing the separation of the gear ring 29 and the corresponding linkage gear 27 or the separation of the bevel gear 3 24 and the bevel gear 1 20 and the bevel gear 2 23, thereby affecting their normal operation.

[0053] Combined with Figure 5 , 6, 7, 8, the linkage component 2 15 includes a linkage sleeve 1 30 and a linkage sleeve 2 31, the ends of the two sleeves that are away from each other are detachably mounted on two adjacent worm gears 19 or two adjacent worm gears 22, and the ends of the two sleeves that are close to each other are provided with mutually cooperating snap-fitting protrusions 32, snap-fitting grooves 33 and an anti-slip limit component 34 for preventing the two sleeves from separating.

[0054] The anti-slip limit assembly 34 includes a plug-in column 35, a movable column 36 and a plurality of anti-slip grooves 37 cooperating with the movable column 36. The plug-in column 35 is fixedly provided inside the linkage sleeve 1 30, and the outer end of the plug-in column 35 is inserted into the linkage sleeve 2 31. The outer end of the plug-in column 35 is provided with a plurality of movable grooves 38 along the circumferential direction. The movable column 36 is slidably set in the movable groove 38, and the two have the same height. As the plug-in column 35 rotates, the outer end of the movable column 36 located at the lower side of the plug-in column 35 extends into the corresponding anti-slip groove 37.

[0055] In the initial state, the two ends of the worm 19 or the worm 22 are respectively installed with a linkage sleeve 1 30 and a linkage sleeve 2 31 .

[0056] Through the above structure, when installing the photovoltaic component 1, the linkage sleeve 1 30 on the photovoltaic component 1 to be installed is docked with the linkage sleeve 2 31 on the installed photovoltaic component 1, so that the locking protrusion 32 is locked with the locking groove 33. In this process, the movable column 36 at the bottom of the plug-in column 35 is first pushed into the movable groove 38 by hand, and the linkage sleeve 1 30 and the linkage sleeve 2 31 are aligned and then the photovoltaic component 1 to be installed is pushed so that the plug-in column 35 is inserted into the linkage sleeve 1 30. When the plug-in (locking) is in place, the movable column 36 located below the plug-in column 35 enters the anti-slip groove 37 under the action of gravity, so that the linkage sleeve 1 30 and the linkage sleeve 2 31 are tightly docked. When the worm 19 and the worm 22 rotate, the plug-in column 35 rotates with it, and the outer end of the movable column 36 located at the lower side of the plug-in column 35 extends into the corresponding anti-slip groove 37, restricting the linkage sleeve 1 30 and the linkage sleeve 2 31 to prevent the two from separating.

[0057] Combined with Figure 1 , 4 5. The linkage sleeve 1 30, linkage sleeve 2 31 and the ends of worm 1 19 and worm 2 22 are connected and fixed by flanges and bolts.

[0058] With the above structure, after the clamping protrusion 32 is damaged due to long-term stress, it can be replaced, thereby avoiding damage to the worm 19 and the worm 2 22 and saving repair and maintenance costs.

[0059] Combined with Figure 5 , 7A limiting block 39 is provided at the inner end of the movable column 36, and a limiting slide groove 40 is correspondingly provided in the movable groove 38, and both ends of the limiting slide groove 40 are sealed.

[0060] The above structure can prevent the movable post 36 from being separated from the movable groove 38 .

[0061] Combined with Fig. 9 The transmission assembly 11 includes a plurality of mutually meshing transmission gears 41, wherein the number of the transmission gears 41 is an odd number. A rack 42 is provided on the side of the telescopic rod 5 close to the cross beam 8. The transmission gears 41 at both ends of the cross beam 8 are respectively meshed with two corresponding racks 42, and the two ends of the rotating cross bar 9 are respectively connected to the transmission gears 41 on the two transmission assemblies 11.

[0062] Through the above structure, the rotating cross bar 9 drives the middle transmission gear 41 to rotate while driving the transmission gears 41 on both sides to rotate, so that the transmission gears 41 at both ends rotate in the same direction, thereby causing the racks 42 on the front and rear support legs to move upward and downward respectively, so that the rear support legs are shortened when the front support legs are extended, and vice versa when the front support legs are shortened, the rear support legs are extended, so that the supporting angle of the solar panel 2 changes.

[0063] Combined with Figure 1 , 2 A plurality of cement piers 56 are arranged on the roof of the building. The cement piers 56 are long strips and are arranged in parallel. The bases 6 corresponding to the photovoltaic components 1 in the same row are all arranged between two adjacent cement piers 56. Fixing ears 57 are provided on both sides of the base 6. The fixing ears 57 are clamped on the cement piers 56 and are fixed to the cement piers 56 by bolts.

[0064] A photoresistor 43 and a wind force detection component 44 are provided on the photovoltaic component 1 at the head end of the same row. The photoresistor 43 and the wind force detection component 44 are electrically connected to the driving motor 16 .

[0065] Combined with Fig.11 , 12, 13, the wind force detection assembly includes a support rod 45 and a windward plate 46, the bottom of the support rod 45 is fixed on the support plate 7, the windward plate 46 is hinged at the top of the support rod 45, and is elastically hinged, here the bottom of the left and right side walls of the windward plate 46 are provided with two hinge shafts, the support rod 45 is correspondingly provided with a hinge seat, and is provided with two hinge holes corresponding to the second hinge shaft, a torsion spring is sleeved on the second hinge shaft, the two ends of the torsion spring are respectively fixedly connected to the side wall of the windward plate 46 and the side wall of the hinge seat, when the torsion spring is in a free state, the windward plate 46 is in a vertical state; a limit switch 47 and a contact block 48 are provided on the top of the support rod 45 and the windward plate 46, here there are two limit switches 47, which are arranged on the hinge seat, and the two limit switches 47 are symmetrical about the windward plate 46 in the vertical state, the contact block 48 is fixedly arranged on the hinge shaft, and the contact block 48 can contact the limit switch 47 during the rotation of the windward plate 46.

[0066] Combined with Figure 1 , a control box is provided on the roof of the building, and a photovoltaic controller is provided inside, the photovoltaic controller (which is a prior art, used to control different drive motor actions to achieve angle adjustment and direction adjustment of the solar panel), four photoresistors 43 are electrically connected to the photovoltaic controller, and the photovoltaic controller compares the resistance values ​​of the front and rear photoresistors 43 to control the drive motor 16 used to adjust the angle of the solar panel 2, and the photovoltaic controller compares the resistance values ​​of the left and right photoresistors 43 to control the drive motor 16 used to adjust the direction of the solar panel 2, and the limit switch 47 is electrically connected to the photovoltaic controller. When any one of the two limit switches 47 is touched by the contact block 48, the drive motor 16 used to adjust the angle of the solar panel 2 is controlled to move, driving the solar panel 2 to lie flat. Note: When the limit switch 47 is touched, the photovoltaic controller no longer compares the resistance values ​​of the front and rear photoresistors 43 to avoid the drive motor 16 being controlled to rotate forward and reverse repeatedly, resulting in burning; only when the contact block 48 leaves the limit switch 47, the photovoltaic controller re-compares the resistance values ​​of the front and rear photoresistors 43 to adjust to the appropriate angle.

[0067] Through the above structure, when the resistance values ​​of the two photoresistors on the front and rear sides of the solar panel 2 are different and the difference exceeds a certain value, the drive motor 16 corresponding to the worm gear 22 is started to adjust the angle of the entire row of solar panels 2; when the resistance values ​​of the photoresistors 43 on the left and right sides are different and the difference exceeds a certain value, the drive motor 16 corresponding to the worm gear 19 is started to adjust the direction of the entire row of solar panels 2.

[0068] In real life, the solar panel 2 is mainly affected by the headwind and the back wind. When the solar panel faces the wind, the wind exerts a backward force on the solar panel 2, which is easy to squeeze the rear supporting legs and cause them to deform and damage. When the solar panel faces the wind, the wind exerts a forward force on the solar panel 2, which is easy to lift up the solar panel 2 and cause damage. A wind force detection device is provided. When the windward panel 46 is blown by the headwind or the back wind, it is caused to rotate forward or backward. When the wind force reaches a certain value, the windward panel 46 rotates to a certain angle, so that the contact block 48 contacts the limit switch 47, and the drive motor 16 corresponding to the worm gear 22 is started to adjust the angle of the entire row of solar panels 2, so that the solar panel 2 lies flat, reducing the contact area with the wind, thereby reducing wind resistance and avoiding wind force from affecting the photovoltaic module 1 and damaging it.

[0069] When the present invention is implemented, during installation, the base 6 is placed between two adjacent cement piers 56. After the first base 6 is fixed, when installing subsequent photovoltaic components, the photovoltaic component 1 to be installed is pushed to make it close to the installed photovoltaic component, and the linkage sleeve 1 30 on it is aligned with the linkage sleeve 2 31 on the installed photovoltaic component 1, and the movable column 36 on the plug-in column 35 is pushed into the corresponding movable groove 38, and the base is continued to be pushed so that the plug-in column 35 extends into the linkage sleeve 1 30, until the movable column 36 at the bottom of the plug-in column 35 extends into the anti-slip groove 37, so that it is snapped into place, and the linkage sleeve 1 30 and the linkage sleeve 2 31 are connected to prevent separation; the subsequent photovoltaic components 1 are installed in sequence and the base 6 and the cement pier 56 are fixed.

[0070] After long-term use, the linkage component 2 15 can be replaced to prevent the clamping protrusion 32 from being damaged by long-term force, which affects the linkage of the entire row of photovoltaic components. When replacing the linkage component 2 15, first clamp the linkage sleeve 1 30 and the linkage sleeve 2 31, and then install and connect them with the worm 1 19 or the worm 2 22 through flanges and bolts.

[0071] The photoresistor 43 senses the light intensity and generates different resistance values, thereby starting the corresponding drive motor 16 to drive the solar panel 2 to move and adjust the angle or direction. When the wind is strong, the windward panel rotates to a certain angle, so that the contact block 48 contacts the limit switch 47, and the corresponding drive motor 16 is started to drive the solar panel 2 to rotate, so that it lies flat to reduce wind resistance.

[0072] When adjusting the support angle of the solar panel 2, the driving motor 16 drives the worm gear 2 22 to rotate, and the other driving motor 16 prevents the rotating sleeve 17 from rotating, and limits the rotation of the rotating ring 25 through the linkage gear set, thereby transmitting through the bevel gear 1 20, the bevel gear 3 24, and the bevel gear 2 23 to rotate the rotating vertical rod 10, and through the transmission bevel gear set to rotate the rotating cross rod 9, and through the transmission gear 41 to drive the racks 42 on both sides to move up and down respectively, so that the solar panel 2 rotates in the vertical plane.

[0073] When adjusting the direction of the solar panel 2, the driving motor 16 drives the worm 19 to rotate, and drives the support plate 7 to rotate through the rotating sleeve 17, thereby driving the solar panel 2 to rotate in the horizontal plane. The other driving motor 16 limits and prevents the bevel gear 20 from rotating. Through the transmission of the linkage gear set, the rotating ring 25 rotates, driving the bevel gear 3 24 to rotate around the bevel gear 20 and rotate on its own, thereby driving the rotating vertical rod 10 to rotate synchronously, so that the two bevel gears of the transmission bevel gear set are relatively stationary, avoiding affecting the support angle of the solar panel 2 when the direction is adjusted.

[0074] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
