Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a driving device and a driving control method of a photovoltaic tracking bracket. Background Art

[0002] Photovoltaic panels, also known as solar panels or photoelectric panels, are devices that convert solar energy into electrical energy.

[0003] Photovoltaic panels are usually composed of multiple photovoltaic cells connected together by connecting wires and circuit boards to convert solar energy into usable electrical energy. Photovoltaic panels are the core components of solar power generation systems and are widely used in homes, businesses and industries. The main material of photovoltaic panels is usually silicon, which can convert solar radiation energy into electrical energy through the photoelectric effect or photochemical effect. Photovoltaic panels are usually covered with a protective layer to protect the solar cells inside.

[0004] The bracket used to support photovoltaic panels is called a photovoltaic bracket. In order to fully utilize solar energy, photovoltaic panels are installed on a large scale using photovoltaic tracking brackets, which can control the angle of the photovoltaic panels in real time according to the direction of light. Since photovoltaic panels are installed on a large scale in large spaces without any obstructions, when there is strong wind, the wind will directly act on the photovoltaic panels, which can easily damage them. Today, photovoltaic tracking technology has matured, but the problem of how to improve wind resistance and protect photovoltaic panels still needs to be solved. Summary of the invention

[0005] The invention discloses a driving device and a driving control method of a photovoltaic tracking bracket, aiming to solve the technical problem of how to improve wind resistance and protect photovoltaic panels.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A driving device of a photovoltaic tracking bracket comprises a base and an upper support, the upper support is attached to the top of the base, the top of the upper support is simultaneously provided with a connecting mechanism and a rotating driving seat, and the rotating driving seat is connected with a driving mechanism, a photovoltaic panel is installed on the driving mechanism, and a shielding mechanism is provided on an inner wall of one side of the upper support; the shielding mechanism comprises a baffle, the inner wall of the top of the upper support is provided with a groove, and the baffle is attached to the top of the groove, two second gas rods are symmetrically fixedly connected in the groove, and the output ends of the two second gas rods are connected to the outer wall of the bottom end of the baffle through a second hinge seat; a connecting rod is connected to the middle position of the groove through a first hinge seat, and one end of the connecting rod is fixedly connected to a support rod, a clamping frame is movably clamped on the support rod, and the clamping frame is fixed to the outer wall of the bottom end of the baffle; a bottom plate is provided at the bottom end of the connecting rod, and the bottom plate is fixed to the inner wall of the groove, the outer walls of the bottom plate on both sides facing each other are respectively fixedly connected with support shafts, and the bottom plate is hinged with an articulated frame through the support shaft, and a torsion spring is connected between the articulated frame and the support shaft.

[0008] By providing a shielding mechanism, the photovoltaic tracking bracket can not only follow the sunlight by rotating the drive seat and the drive mechanism, but also change the angle of the photovoltaic panel according to the wind force and wind direction, so as to reduce the damage of the wind to the photovoltaic panel. In the shielding mechanism, when strong wind is detected, the connecting rod can be connected to the baffle, and under the continuous retraction of the second gas rod and the limiting action of the connecting rod, the baffle can be tilted with the second hinge seat as the axis until it covers the bottom end of the photovoltaic panel in an inclined state, thereby covering and protecting the bottom edge of the photovoltaic panel. Under the dual effects of changing the inclination angle of the photovoltaic panel and covering and protecting its bottom edge, the damage of the photovoltaic panel to the strong wind can be reduced, thereby ensuring the safety of the photovoltaic panel in a windy environment.

[0009] The top of the second support is fixedly provided with a third slide block, and the top of the third slide block is fixedly connected to the third slide block, and the third slide block is movably engaged with the first slide block.

[0010] A connecting mechanism is provided, in which the upper support is fixed to the top of the base by an electromagnet. At this time, the upper support can stabilize the photovoltaic bracket, and at the same time, it is movably connected to the first arc-shaped slide groove through the first slider, and can also support the driving mechanism. When strong winds are detected, the driving mechanism can be connected to the upper support through the connecting mechanism, and the upper support can be driven to rotate during the rotation of the driving mechanism, thereby ensuring that the shielding mechanism can accurately cover the bottom end of the photovoltaic panel and will not drive the upper support to rotate repeatedly during daily sunlight tracking.

[0011] A driving control method for a driving device of a photovoltaic tracking bracket comprises the following specific steps:

[0012] S1: Wind direction monitoring;

[0013] S2: The driving mechanism is reset under the action of the rotating driving seat, so that the second slider is movably engaged with the middle position of the second arc-shaped sliding groove;

[0014] S3: The first gas rod drives the plug to extend, establishing a connection between the upper support and the driving mechanism;

[0015] S4: The electromagnet is powered off, and the rotating drive seat drives the drive mechanism and the upper support to rotate in the wind direction at the same time;

[0016] S5: The driving mechanism drives the photovoltaic panel to tilt toward the wind direction, so that it faces the wind direction at an angle of 30°-45°;

[0017] S6: the shielding mechanism is opened, so that the baffle covers the bottom end of the photovoltaic panel in an inclined state;

[0018] The S1 comprises the following specific steps:

[0019] S11: Receive online wind warning information and estimate the strongest wind period;

[0020] S12: Calculate whether the wind force value is within the safety threshold of the photovoltaic rack support force, and derive a progressive segmentation value of the safety threshold;

[0021] S13: Using a wind vane to monitor in real time, and comparing it with the predicted wind evolution value, if it is higher than the predicted value, and the predicted value and the monitored value are close to or greater than the corresponding progressive segmentation value of the safety threshold, then the driving mechanism and the rotating driving seat are controlled to drive the photovoltaic panel to enter the defense mode;

[0022] S14: When the monitored value is lower than the predicted value, and the predicted value and the monitored value are less than the corresponding progressive segmentation value of the safety threshold, the position of the photovoltaic panel is controlled in the original photovoltaic tracking mode.

[0023] By setting the progressive segmentation value of the safety threshold, the maximum wind force that can be sustained is calculated based on the safety threshold of the photovoltaic frame support force, and then progressed forward to correspond to the progressive mode of wind force from small to large. Based on real-time monitoring data, the progressive segmentation value of the corresponding time period is matched and analyzed. This can improve the accuracy of wind force prediction, and start the photovoltaic panel defense mode in windy weather in advance. It can also avoid entering the defense mode too early based on the online wind warning information, which leads to the failure to fully utilize light energy and causes energy waste.

[0024] As can be seen from the above, a driving device of a photovoltaic tracking bracket includes a base and an upper support, the upper support is attached to the top of the base, the top of the upper support is provided with a connecting mechanism and a rotating drive seat, and the rotating drive seat is connected with a driving mechanism, a photovoltaic panel is installed on the driving mechanism, and a shielding mechanism is provided on the inner wall of one side of the upper support; the shielding mechanism includes a baffle, the inner wall of the top of the upper support is provided with a groove, and the baffle is attached to the top of the groove, and two second gas rods are symmetrically fixedly connected in the groove, and The output ends of the two second gas rods are connected to the outer wall of the bottom end of the baffle through the second hinge seat; the middle position of the groove is connected to a connecting rod through the first hinge seat, and one end of the connecting rod is fixedly connected to a support rod, and a clamping frame is movably clamped on the support rod, and the clamping frame is fixed to the outer wall of the bottom end of the baffle; the bottom end of the connecting rod is provided with a bottom plate, and the bottom plate is fixed to the inner wall of the groove, and the outer walls on both sides of the bottom plate facing each other are respectively fixedly connected to support shafts, and the bottom plate is hinged to the hinge frame through the support shaft, and a torsion spring is connected between the hinge frame and the support shaft.

When a strong wind is detected and the photovoltaic panel 5 is driven to tilt in the wind direction, the shielding mechanism 4 can be driven to move to the lower part of the photovoltaic panel 5 through the connecting mechanism 1 at the same time. At this time, the second gas rod 403 extends to drive The baffle 401 extends out, and when the card-joining frame 409 contacts the connecting rod 405, the connecting rod 405 can be squeezed. When the baffle 401 moves outward and then resets inward, under the action of the torsion spring 411, the connecting rod 405 returns to its original position, and the card interface of the card-joining frame 409 is just engaged with the support rod 408, so that the connecting rod 405 is connected to the baffle 401. Under the continuous retraction of the second gas rod 403 and the limiting action of the connecting rod 405, the baffle 401 can be tilted with the second hinge seat 406 as the axis until it covers the photovoltaic panel 5 in a tilted state. The bottom end of the photovoltaic panel 5 is covered and protected thereby.

When strong wind is detected, the driving seat 7 is rotated to drive the driving mechanism 6 to rotate and reset, so that the second slider 111 is clamped in the middle position of the second arc-shaped slide groove 104. When the first gas rod 112 is pushed out, the plug block 109 can be driven to extend and fit on both sides of the first slider 102. When the electromagnet is powered off, the upper support 2 can be driven to rotate during the rotation of the driving mechanism 6, thereby ensuring that the shielding mechanism 4 can accurately cover the bottom end of the photovoltaic panel 5, and will not drive the upper support 2 to rotate repeatedly during daily sunlight tracking.
