Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a solar tracking bracket. Background Art

[0002] In the context of the world advocating green energy, solar power generation, as an important component of green energy, is being vigorously developed and researched by various countries.

[0003] Solar panels need to be fixed by solar panel brackets, and track the changes in the sun's position in real time, and adjust the light receiving angle of the solar panel brackets to maximize the use of light and improve power generation efficiency.

[0004] In the prior art, a Chinese invention patent with authorization publication number CN118232809B discloses a dual-axis solar tracking bracket, comprising a base, a rotating shaft, a mounting bracket, and an adjustment mechanism. The rotating shaft is inserted into the base and can rotate about its own axis to change the azimuth angle of the photovoltaic panel. The mounting bracket is arranged on top of the rotating shaft and can rotate about a first axis to change the pitch angle of the photovoltaic panel. The first axis is perpendicular to the axis of the rotating shaft. The photovoltaic panel is mounted on the mounting bracket during use. The adjustment mechanism is configured to both drive the mounting bracket to rotate and prevent vibration of the photovoltaic panel. During use, on the one hand, the linkage between the rotating shaft and the mounting bracket enables the photovoltaic panel to always track the sun, ensuring the photovoltaic panel's efficiency in absorbing sunlight. On the other hand, when the photovoltaic panel is vibrated by external forces, the adjustment mechanism can promptly offset the energy generated by the vibration of the photovoltaic panel, avoiding any impact on the photovoltaic panel.

[0005] The problems with existing technologies are that they have complex structures and high construction and maintenance costs. The adjustment functions that solar panels need to implement are relatively simple and fixed. For large-scale photovoltaic power generation equipment, the economic benefits are not ideal, and it is necessary to continue to make improvements. Utility Model Content

[0028] Technologies, methods, and devices known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technologies, methods, and devices should be regarded as part of the specification.

[0029] As Figure 1 、 Figure 2 As shown in [figures not provided], a specific embodiment of a solar tracking device includes a solar panel support 1, a U-shaped connector 2, a semi-circular steel support 3, a rope fixing structure 4, a left corrosion-resistant rope 5, a right corrosion-resistant rope 6, an azimuth adjustment motor 7, a rope driving wheel 8, a pitch adjustment motor 9, and a support 10.

[0030] The solar panel support 1 is used to carry and fix the solar panel. In some embodiments, 4 connectors are symmetrically arranged at the bottom of the solar panel support 1, namely 2 U-shaped connectors 2 and 2 rope fixing structures 4. The connection line of the 2 U-shaped connectors 2 is perpendicular to the connection line of the 2 rope fixing structures 4.

[0031] In some embodiments, the semi-circular steel support 3 is a semi-circular structure as a whole, made of stainless steel material. Pin holes are coaxially arranged along the radial direction at both ends of the semi-circular steel support 3 for installing positioning pins. The 2 U-shaped connectors 2 are respectively hinged to both ends of the semi-circular steel support 3 through 1 positioning pin. After installation, there is only one degree of rotational freedom about the axis of the pin hole between the solar panel support 1 and the semi-circular steel support 3.

[0032] In some embodiments, a motor fixing seat is provided in the middle of the inner side of the semi-circular steel bracket 3 for installing the azimuth adjustment motor 7. The output shaft of the azimuth adjustment motor 7 is equipped with a rope driving wheel 8 for driving the left corrosion-resistant rope 5 and the right corrosion-resistant rope 6. The left corrosion-resistant rope 5 and the right corrosion-resistant rope 6 are respectively connected to one of the rope fixing structures 4. The left corrosion-resistant rope 5 and the right corrosion-resistant rope 6 can be two parts of the same rope, located on both sides of the semi-circular steel bracket 3 respectively. According to the position division, the length changes are always the same and the trends are opposite during the adjustment process, that is, when the left corrosion-resistant rope 5 shortens, the right corrosion-resistant rope 6 elongates, and when the left corrosion-resistant rope 5 elongates, the right corrosion-resistant rope 6 shortens, driving the solar panel bracket 1 to achieve azimuth adjustment.

[0033] In some embodiments, the left corrosion-resistant rope 5 and the right corrosion-resistant rope 6 are made of steel ropes soaked in corrosion-resistant paint.

[0034] In some embodiments, the rope driving wheel 8 is machined from stainless steel material. To increase the friction force and ensure the adjustment accuracy, anti-slip grooves are also machined at the parts where the rope driving wheel 8 contacts the left corrosion-resistant rope 5 and the right corrosion-resistant rope 6.

[0035] In some embodiments, the bracket 10 is used to support the entire solar tracking device and the solar panel, and is fixedly installed on the ground, roof or other positions. The pitch adjustment motor 9 is arranged on the side of the bracket 10 away from the installation surface. Gear teeth are provided on the outer side of the semi-circular steel bracket 3. The output shaft of the pitch adjustment motor 9 is equipped with a gear, and the semi-circular steel bracket 3 is driven to rotate through gear meshing to achieve pitch adjustment.

[0036] To achieve azimuth and pitch adjustment, corresponding control devices also need to be configured. The start of the azimuth adjustment motor 7 and the pitch adjustment motor 9 requires power supply, which are all mature solutions existing in the prior art. Those skilled in the art only need to make adaptive modifications during the implementation process and will not be elaborated here.

[0037] In some embodiments, when the azimuth angle and / or pitch angle between the sun and the solar panel changes by more than 1°, the system will automatically identify and issue an instruction to control the pitch adjustment motor 9 to rotate and stop, driving the solar panel bracket 1 to rotate in the pitch direction through the semi-circular steel bracket 3; as needed, the system will automatically identify and issue an instruction to control the azimuth adjustment motor 7 to rotate and stop, driving the left corrosion-resistant rope 5 and the right corrosion-resistant rope 6 to synchronously elongate / shorten through the rope driving wheel 8, changing the lengths of the left corrosion-resistant rope 5 and the right corrosion-resistant rope 6 exposed outside, and further driving the solar panel bracket 1 to rotate in the azimuth direction.

[0038] The beneficial technical effects that can be achieved by the above specific embodiments are:

[0039] The proposed solar tracking device can adjust the azimuth angle and / or the pitch angle, meet the need for adjusting the direction of the solar panel at multiple angles, maximize the utilization of solar energy for power generation, and at the same time has a simple structure and is easy to maintain, which can significantly reduce the construction and maintenance costs of photovoltaic equipment.
