Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic automatic tracking devices, in particular to a photovoltaic automatic tracking distributed control system. Background Art

[0002] As is known to all, solar energy is an inexhaustible and renewable energy source for mankind. It has the advantages of sufficient cleanliness, absolute safety, relative extensiveness, indeed long life and maintenance-free, sufficient resources and potential economy. It plays an important role in the long-term energy strategy. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It mainly consists of three parts: photovoltaic panels, controllers and inverters. Photovoltaic automatic tracking technology is to increase the power generation by tracking the trajectory of the sun and increasing the luminous flux per unit area of ​​the photovoltaic panels, that is, to achieve synchronous adjustment of the position of the photovoltaic panels following the trajectory of the sun, so as to improve the power generation efficiency and reduce light loss.

[0003] For example, the Chinese utility model patent with authorization announcement number CN205670263U, titled "A Photovoltaic Automatic Tracking Distributed Control System", specifically includes a data server, a tracking control system, and a tracking execution system. The tracking control system connected to the data server is also connected to an environmental data sensor. The tracking control system is connected to at least one tracking execution system through a wireless data transmission unit composed of a wireless transmitting module and a wireless receiving module. The tracking execution system is a self-tracking closed-loop control structure, in which the microcontroller is connected to a drive device that controls the movement of the photovoltaic unit through a boost module, and the inclination sensor installed on the drive device is connected to the microcontroller through an A / D unit; the microcontroller drives the drive device to rotate through the boost module, and the inclination sensor transmits the collected drive device status signal back to the microcontroller to complete the self-tracking function.

[0004] Another example is the Chinese invention patent with application publication number CN106452322A, entitled "A solar photovoltaic panel adjustment bracket", which specifically includes a frame, an elastic component is provided at the lower part of the frame, an intermediate plate is provided at the upper part of the frame, a pillar is provided at the upper part of the intermediate plate, a support plate is fixedly connected to the upper part of the pillar, two relatively arranged brackets are installed at one end of the upper part of the support plate, a rotating shaft is provided on the upper part of the two brackets, a driving mechanism is provided at one end of the rotating shaft, a plurality of connecting members are fixed on the rotating shaft, one end of the photovoltaic panel fixing mechanism is hinged at the end of the connecting member, and the other end is hinged to the hinged ear seat on the support plate; the connecting member includes a connecting block, an axial hole passing through the rotating shaft is provided on the connecting block, a connecting rod is provided on the side of the connecting block, a first ball joint is provided at the end of the connecting rod, the first ball joint is further connected to the intermediate rod, the end of the intermediate rod is connected to the second ball joint, the second ball joint has an opening, the opening is connected to the second ball joint by a connecting bolt, and the end rod is universally hinged in the opening.

[0005] Similar to the aforementioned application, existing photovoltaic automatic tracking distributed control systems generally include two methods for adjusting the tracking mechanism of photovoltaic panels. One method, similar to the aforementioned solar photovoltaic panel adjustment bracket (CN106452322A), uses two adjustment brackets to support and adjust the photovoltaic panel from the rear side. Although this adjustment method achieves stable angle adjustment, in actual use, it is prone to errors in the adjustment of the two adjustment brackets due to friction gaps, deformation, or thermal expansion and contraction, resulting in adjustment interference. The other method uses a single adjustment shaft that is connected to the photovoltaic panel in conjunction with a mounting mechanism. The rotation of the adjustment shaft drives the photovoltaic panel to achieve tracking adjustment. This adjustment method uses a single adjustment shaft for adjustment, which can effectively prevent errors and adjustment interference caused by the simultaneous adjustment of multiple adjustment parts. However, in actual adjustment, since the single adjustment shaft is connected to the photovoltaic panel for adjustment, it is a rotational adjustment of the linear rotation drive surface. At different angles, the center of gravity of the photovoltaic panel changes, which seriously affects the stability of the adjustment. This can lead to uneven load on the adjustment mechanism, causing damage or gaps, affecting the accuracy of the adjustment. Summary of the Invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-11 , an embodiment of the present invention provides a technical solution:

[0037] A photovoltaic automatic tracking distributed control system includes a main support 1 and a photovoltaic panel assembly. The main support 1 is provided with an adjustment shaft 2 that rotates horizontally, and the photovoltaic panel assembly is provided on the adjustment shaft 2. The main support 1 is provided with a bearing portion 12, and the photovoltaic panel assembly is provided with an auxiliary support portion 5. When the photovoltaic panel assembly is tracking and adjusting, the auxiliary support portion 5 rotates and abuts against the bearing portion 12 to achieve auxiliary support for the photovoltaic panel assembly. This embodiment provides a photovoltaic automatic tracking distributed control system, which is used to control the photovoltaic panel assembly to swing and adjust by tracking the trajectory of the sun, thereby increasing the luminous flux per unit area of ​​the photovoltaic panel assembly to increase power generation. Specifically, the main support 1 is a mounting bracket for the photovoltaic panel assembly. A bearing seat 11 is fixed at the top of the main support 1. The adjustment shaft 2 passes through the bearing seat 11 and is rotatably connected to the bearing seat 11. The photovoltaic panel assembly is installed on the adjustment shaft 2 to achieve tracking and adjustment of the photovoltaic panel assembly by rotating the adjustment shaft 2. The main control box 10 is also included. The main control box 10 is used to collect local geographic coordinates and calculate local phase information. For the parameters of the sun's trajectory, the parameters of the sun's trajectory change are converted into the operating hours of the driving device per unit time, and a control signal is generated and transmitted to the control mechanism. The control mechanism drives the adjustment shaft 2 to swing and adjust. A bearing part 12 is provided on the main bracket 1, and an auxiliary support part 5 is provided on the photovoltaic panel assembly. For example, the bearing part 12 is a ring structure fixed on the main bracket 1, and the centerline axis of the ring structure coincides with the centerline axis of the swing adjustment motion path of the photovoltaic panel assembly, so that the auxiliary support part 5 on the photovoltaic panel assembly abuts against the bearing part 12 when the photovoltaic panel assembly is adjusted, thereby assisting in supporting the photovoltaic panel assembly.

[0038] The photovoltaic automatic tracking and distributed control system provided in this embodiment is provided with an adjustment shaft 2 which is arranged to rotate horizontally with a bearing seat 11 at the top end of the main support 1. The adjustment shaft 2 is connected to the photovoltaic panel assembly to adjust the photovoltaic panel assembly, and the photovoltaic panel assembly is tracked and adjusted by a single adjustment shaft 2, which effectively avoids the problem of adjustment interference caused by errors caused by simultaneous synchronous adjustment of the photovoltaic panel assembly by multiple adjustment brackets. Furthermore, a bearing portion 12 is provided at the top end of the main support 1, and an auxiliary support portion 5 is provided on the photovoltaic panel assembly, so that when the adjustment shaft 2 drives the photovoltaic panel assembly to swing and adjust, the auxiliary support portion 5 abuts against the bearing portion 12 to assist in supporting the photovoltaic panel assembly, thereby improving the load stability during adjustment, enhancing the stability and accuracy of adjustment of the photovoltaic panel assembly, and at the same time protecting the adjustment shaft 2 and the driving mechanism 3, thereby reducing the probability of failure.

[0039] In another embodiment provided by the present invention, a driving mechanism 3 is provided at the top of the main frame 1, and the driving mechanism 3 is connected to the adjusting shaft 2 in a transmission manner to drive the adjusting shaft 2 to drive the photovoltaic panel 6 to track and adjust. Specifically, the driving mechanism 3 includes a driving gear box 31, which is fixed to the main frame 1. The inner side of the driving gear box 31 is rotatably engaged with a worm wheel 33 and a worm 32. The worm wheel 33 is fixedly sleeved on the adjusting shaft 2. A driving motor 34 is fixed to the outside of the gear box 31. The driving motor 34 is connected to the worm 32 through a reducer. The main control box 10 transmits a control signal to the driving motor 34. The driving motor 34 receives the control signal to drive the worm 32 to rotate. The worm 32 drives the adjusting shaft 2 to rotate through the worm wheel 33. Finally, the adjusting shaft 2 drives the photovoltaic panel 6 to track and adjust, thereby increasing the luminous flux per unit area of ​​the photovoltaic panel 6 and thus increasing the power generation.

[0040] In another embodiment provided by the present invention, the photovoltaic panel 6 is connected to the adjustment shaft 2 via a combined connector 4, and the auxiliary support portion 5 is provided on the combined connector 4. The combined connector 4 includes two M-shaped mounting brackets 41 symmetrically fixed to the back of the photovoltaic panel 6, and a connecting bracket 43 is provided in parallel between the two M-shaped mounting brackets 41, and the two connecting brackets 43 are fixed to the two ends of the adjustment shaft 2. Two M-shaped mounting brackets 41 are symmetrically fixed to the top and bottom of the back of the photovoltaic panel 6, wherein the two M-shaped mounting brackets 41 are parallel to the adjustment shaft 2, and a connecting bracket 43 is symmetrically connected between the two ends of the two M-shaped mounting brackets 41, that is, the two connecting brackets 43 are perpendicular to the adjustment shaft 2, and the middle sections of the two connecting brackets 43 are fixed to the two ends of the adjustment shaft 2 to achieve the installation and fixation of the photovoltaic panel 6.

[0041] In another embodiment provided by the present invention, preferably, the auxiliary support portion 5 includes a support roller 51, which is rotatably arranged between the two connecting frames 43, and the support roller 51 abuts against the surface of the load-bearing portion 12. The central axis of the rotation path of the support roller 51 coincides with the central axis of the load-bearing portion 12, and the supporting protrusions 13 are evenly arranged on the circumferential side of the load-bearing portion 12. The surface of the support roller 51 is evenly provided with connecting protrusions 52, and the connecting protrusions 52 are meshed with the supporting protrusions 13. Specifically, the support roller 51 is rotatably arranged between the two connecting frames 43. When the adjusting shaft 2 drives the photovoltaic panel 6 to rotate and adjust, the support roller 51 is simultaneously driven to rotate and adjust. Since the center axis of the rotation adjustment path of the support roller 51 coincides with the center axis of the bearing part 12, when the photovoltaic panel 6 rotates, the bearing part 12 always abuts against the support roller 51 to support the photovoltaic panel 6. Furthermore, there are two support rollers 51, and the two support rollers 51 are located on both sides of the bearing part 12 to achieve synchronous rotation support on both sides of the photovoltaic panel 6, further improving the stability of the support. Furthermore, connecting protruding teeth 52 are evenly arranged on the circumference of the support roller 51. When the support roller 51 is in rotation and abutting contact with the bearing part 12, the connecting protruding teeth 52 on the support roller 51 and the supporting protruding teeth 13 on the bearing part 12 are rotationally engaged to achieve mutual bite support, further improving the stability of the support.

[0042] In another embodiment provided by the present invention, two sets of movable connectors 42 are provided on each of the two M-shaped mounting frames 41. A connecting frame 43 is connected between two opposing movable connectors 42 on the two M-shaped mounting frames 41. The movable connectors 42 are used to provide a movable space between the connecting frame 43 and the M-shaped mounting frames 41. A vibration mechanism is also provided on the support roller 51. When the photovoltaic panel 6 is rotated and adjusted, the vibration mechanism synchronously drives the photovoltaic panel 6 to vibrate. Specifically, the movable connecting member 42 includes a connecting pin 421 fixed on the M-shaped mounting frame 41 and a connecting hole 431 opened on the connecting frame 43, and the connecting hole 431 is slidably sleeved on the connecting pin 421, and the free end of the connecting pin 421 is formed with an end head, the diameter of the end head is larger than the diameter of the connecting hole 431, and the connecting pin 421 is located on the outer side of the connecting frame 43 and a supporting spring 422 is provided. The elastic force of the supporting spring 422 is used to drive the connecting frame 43 and the M-shaped mounting frame 41 to fit each other, so that there is an elastic activity space between the photovoltaic power generation panel 6 and the connecting frame 43, and a vibration mechanism is provided on the support roller 51, and the vibration mechanism includes a rotating wheel and a vibration frame 44, the rotating wheel is fixedly sleeved on the supporting roller 51, and the edge of the rotating wheel includes two sections with different distances from the central axis of the supporting roller 51, the rotating wheel is a cam 53, and optionally, the rotating wheel is an eccentric wheel or an elliptical wheel, and the vibration frame 44 is connected between the two M-shaped mounting frames 41, and the position of the vibration frame 44 is consistent with the position of the rotating wheel Corresponding to each other, since connecting protruding teeth 52 are evenly arranged on the circumference of the support roller 51, when the support roller 51 rotates and abuts against the bearing part 12, the connecting protruding teeth 52 on the support roller 51 rotate and engage with the supporting protruding teeth 13 on the bearing part 12, so that when the photovoltaic panel 6 rotates and adjusts, the support roller 51 rotates and adjusts synchronously. When the support roller 51 rotates and adjusts synchronously, it drives the end of the wheel edge that is farther away from the central axis of the support roller 51 to intermittently knock on the vibration frame 44, thereby driving the photovoltaic panel 6 to vibrate through the vibration frame 44. In rainy and snowy weather, when snow accumulates on the surface of the photovoltaic panel 6, the photovoltaic automatic tracking distributed control system can synchronously drive the photovoltaic panel 6 to vibrate when swinging and adjusting the photovoltaic panel 6 to assist in clearing the snow, so that the snow attached to the photovoltaic panel 6 automatically slides off, making cleaning convenient. The photovoltaic automatic tracking distributed control system also has dual measures to assist in cleaning the snow on the photovoltaic panel 6, making it more convenient to use.

[0043] In another embodiment provided by the present invention, preferably, the vibration mechanism includes a rotating wheel, which is fixedly sleeved on the supporting roller 51, and the circumference of the rotating wheel is pneumatically telescopically embedded with an arc-shaped convex portion. Specifically, a groove is provided on the circumference of the wheel, and an arc-shaped convex portion is connected to the groove through a pneumatic telescopic mechanism. The arc-shaped convex portion has two working states. In the first working state, the arc-shaped convex portion is embedded in the circumference of the wheel, and the wheel is in a circular state. In the second working state, the arc-shaped convex portion protrudes to the outside of the quasi-wheel. At this time, there is a convex portion on the circumference of the wheel to realize that when the wheel rotates, the protruding arc-shaped convex portion drives the photovoltaic panel 6 to vibrate to assist in clearing snow. That is, when the photovoltaic panel 6 is tracked and adjusted, the arc-shaped convex portion on the control wheel is in the first working state. At this time, the photovoltaic panel 6 will not be driven to vibrate when it is adjusted. When the photovoltaic panel 6 is adjusted to assist in clearing snow, the arc-shaped convex portion on the control wheel is in the second working state. At this time, when the photovoltaic panel 6 is adjusted, the photovoltaic panel 6 is synchronously driven to vibrate by the wheel to assist in clearing snow.

[0044] In another embodiment provided by the present invention, preferably, a synchronous self-locking mechanism 54 is provided on the connecting frame 43, and the synchronous self-locking mechanism 54 is rotatably connected to the support roller 51, and a locking groove 423 is provided on the connecting pin 421 for cooperating with the synchronous self-locking mechanism 54. The synchronous self-locking mechanism 54 has two working strokes. In the first working stroke, when the support roller 51 drives the convex part on the rotating wheel to drive the vibration frame 44 to drive the photovoltaic panel 6 to vibrate, the synchronous self-locking mechanism 54 is disengaged from the locking groove 423. In the second working stroke, when the support roller 51 drives the convex part on the rotating wheel to separate from the vibration frame 44, the synchronous self-locking mechanism 54 is embedded in the locking groove 423, so as to fix the movable connecting member 42 when there is no vibration, that is, to fix the photovoltaic panel 6 to the connecting frame 43, thereby improving the stability of the photovoltaic panel 6.

[0045] Furthermore, the support roller 51 is arranged between the two connecting frames 43 through the rotation of the damping shaft, and the support roller 51 abuts against the surface of the load-bearing part 12. The central axis of the rotation path of the support roller 51 coincides with the central axis of the load-bearing part 12. The peripheral side of the load-bearing part 12 is located in the tracking and adjustment movement path area of ​​the shaft roller 51, and the load-bearing part 12 is located on the movement path of the rotating roller 51 for cleaning and adjustment, and a tooth groove is provided. The surface of the support roller 51 is evenly provided with connecting convex teeth 52, and the connecting convex teeth 52 are engaged with the tooth groove. When the photovoltaic panel 6 is performing tracking adjustment, the rotation resistance of the support roller 51 is greater than the friction resistance of the abutment, and the support roller 51 does not rotate axially. When the photovoltaic panel 6 is performing auxiliary cleaning, the connecting convex teeth 52 are engaged with the tooth groove to drive the support roller 51 to rotate, thereby synchronously driving the photovoltaic panel 6 to vibrate through the wheel to assist in clearing snow.

[0046] Specifically, the frequency-synchronous self-locking mechanism 54 includes a rotating sleeve 541, which is fixed on the connecting frame 43, and a rotating shaft 542 is rotatably provided on the inner side of the rotating sleeve 541. One end of the rotating shaft 542 is coaxially connected to the supporting roller 51, and the rotating shaft 542 is located inside the rotating sleeve 541 and an adjusting disk 543 is fixed at one end. An adjusting link 544 is eccentrically connected to the adjusting disk 543, and a locking pin 545 is rotatably connected to the adjusting link 544. The locking pin 545 passes through the connecting frame 43 and extends to the inner side of the connecting hole 431. The eccentric connection position of the adjusting link 544 is opposite to the position of the convex portion on the cam 53 with respect to the supporting roller 51. When the supporting roller 51 drives the cam 53 to rotate, when the cam 53 rotates close to the vibration frame 44, the adjusting disk 543 cooperates with it. The connected adjusting link 544 drives the locking pin 545 away from the connecting hole 431, that is, the locking pin 545 is pulled out from the locking groove 423 opened on the connecting pin shaft 421 to achieve unlocking, so that the cam 53 cooperates with the vibration frame 44 to synchronously drive the photovoltaic panel 6 to vibrate to assist in clearing snow. When the cam 53 rotates away from the vibration frame 44, under the elastic force of the support spring 422, the connecting frame 43 and the M-shaped mounting frame 41 fit together, and the adjusting disk 543 cooperates with the adjusting link 544 connected thereto to drive the locking pin 545 to embed into the connecting hole 431, that is, the locking pin is clamped into the locking groove 423 opened by 545 from the connecting pin shaft 421, thereby fixing the connecting pin shaft 421, that is, fixing the photovoltaic panel 6 and the connecting frame 43, thereby improving the stability of the photovoltaic panel 6.
