Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, in particular to a photovoltaic base and photovoltaic equipment that are easy to install. Background Art

[0002] With the development of new energy technologies, photovoltaic power generation technology is increasingly being adopted in power generation projects. A photovoltaic power generation system is a complete system that converts solar energy into electricity. To improve the energy collection efficiency of photovoltaic power generation systems, regular cleaning of the panels to remove dust and impurities and adjusting the panels' orientation and angle are effective measures. The construction of common photovoltaic power generation systems is often very time-consuming and labor-intensive, with the installation of the photovoltaic base being the starting point and key point. The photovoltaic base is crucial infrastructure for installing photovoltaic modules, primarily securing and supporting them and adjusting their angle and orientation. Currently, many photovoltaic power generation systems lack the ability to adjust the angle of the panels, resulting in inadequate utilization of sunlight. Therefore, simplifying the installation of photovoltaic systems and improving their efficiency remain two key technical challenges in the photovoltaic power generation field.

[0003] Among the numerous photovoltaic power generation projects currently available, photovoltaic bases are divided into three types according to their structural types: the first is a single-column base, which is characterized by a simple structure and is usually supported by a single vertical pillar. This type of base has a low installation cost and is easy to install and maintain, but its disadvantage is that it cannot be used in application scenarios where the tilt angle needs to be adjusted. The second is a double-column base, which is characterized by being supported by two vertical pillars, with a relatively stable structure, and is suitable for application scenarios where the tilt angle needs to be adjusted. Its disadvantage is that it has high requirements for support columns and the installation cost is relatively high. The third type is a frame-type base, which is characterized by a frame structure design and is usually composed of horizontal beams, longitudinal beams, and support columns. It has a stable structure and is suitable for installation in various terrains and complex conditions. The tilt angle and direction can be adjusted. Its disadvantage is also the high complexity of the base structure and the relatively high cost of installation and construction.

[0041] Please refer to Figure 1 - Figure 7An embodiment of the present invention provides a photovoltaic base 100 that is easily installed and is located on the ground for installing a photovoltaic panel 200 and adjusting the orientation of the photovoltaic panel 200. The photovoltaic panel 200 is characterized in that a back plate 30 is provided at the bottom thereof, and an arc-shaped groove 31 and a positioning column 32 are provided on the back plate 30. The arc-shaped groove 31 is integrally formed on the back plate 30, and the positioning column 32 is located at the starting end and the ending end of the arc-shaped groove 31. The photovoltaic base 100 includes: a base 10 and a fixed shaft 20.

[0042] The base 10 is made of aluminum alloy and is in the shape of a triangular prism, supporting the photovoltaic panel 200. The cylindrical fixed shaft 20 is integrally formed above the base 10. Magnetic sheets 21 are bonded to each end of the fixed shaft 20 and located on the circular surfaces of the fixed shaft 20. The back plate 30 is provided with a magnetic sheet 21, which is bonded to the back plate 30 and located on the positioning posts 32 of the back plate 30. The magnetic sheet 21 is located on the side of the positioning posts 32 that is closest to the arcuate groove 31. The magnetic sheet 21 on the back plate 30 and the magnetic sheet 21 on the fixed shaft 20 have opposite magnetic properties. The arcuate groove 31 is the same length as the fixed shaft 20, and the radius of the arcuate groove 31 is the same as the radius of the fixed shaft 20. The magnetic piece 21 on the positioning column 32 is attracted to the magnetic piece 21 of the fixed shaft 20, and the arc groove 31 is embedded in the fixed shaft 20 to install the photovoltaic panel 200. The photovoltaic panel 200 rotates around the axial direction F1 on the fixed shaft 20 to adjust the orientation of the photovoltaic panel 200.

[0043] Among them, aluminum alloy has excellent strength and stability, and can bear the weight of the photovoltaic panel 200 and maintain structural stability. The choice of this material can ensure that the photovoltaic panel 200 can remain stable under various environmental conditions and is not prone to deformation or damage. Aluminum alloy is relatively lightweight compared to other metal materials, which can reduce the overall weight of the photovoltaic panel 200 system. This is very convenient for the installation, transportation and maintenance of the photovoltaic panel 200, and can also reduce the pressure on the supporting structure and extend its service life. Aluminum alloy has good corrosion resistance and can resist erosion from most external environmental factors, including moisture, oxidation, etc. This allows the substrate 10 to be used for a long time in an outdoor environment without being easily damaged, thereby increasing the service life of the photovoltaic panel 200. Aluminum alloy, as a common material, is relatively mature in manufacturing and processing and has a low cost. Therefore, choosing aluminum alloy as the material of the substrate 10 can not only meet the requirements of structural strength and stability, but also control manufacturing costs and improve the competitiveness of the product.

[0044] The fixed shaft 20 is integrally formed above the base 10 and is cylindrical in shape, which helps provide a stable support point and ensures that the photovoltaic panel 200 remains balanced and stable when installed on the fixed shaft 20. At the same time, magnetic sheets 21 are provided at both ends of the fixed shaft 20, which can be easily magnetically connected to other components, improving the convenience and efficiency of installation. The positioning column 32 on the back plate 30 is provided with a magnetic sheet 21, and the magnetic sheet 21 is magnetically opposite to the magnetic sheet 21 on the fixed shaft 20. This setting ensures that the photovoltaic panel 200 forms a stable magnetic connection with the fixed shaft 20 during installation, allowing it to rotate freely on the fixed shaft 20 while maintaining good fixation. The arc-shaped groove 31 has the same length and radius as the fixed shaft 20 and is embedded in the fixed shaft 20. This design ensures that the photovoltaic panel 200 can be firmly installed on the fixed shaft 20 and rotate along the axial direction F1 on the fixed shaft 20 to adjust the orientation of the photovoltaic panel 200 so that it can better receive solar energy and improve power generation efficiency.

[0045] More preferably, the base 10 includes a base 11 and a support frame 12 .

[0046] The base 11 is connected to the ground and is located above the ground. The support frame 12 is provided on a side of the base 11 facing away from the ground. The support frame 12 is made of aluminum alloy.

[0047] Among them, the base 11 is directly connected to the ground, providing a solid foundation that can effectively support the entire photovoltaic equipment, making it less susceptible to tilting or movement due to the influence of the external environment. The base 11 and the support frame 12 are made of aluminum alloy, which has good corrosion resistance and durability. They can withstand the wind and rain of the outdoor environment for a long time and extend the service life of the equipment. Placing the base 11 above the ground can better distribute the weight of the equipment, reduce the pressure on the ground, and avoid sinking or damage to the foundation due to long-term pressure. This setting makes the installation and maintenance of the equipment more convenient. The base 11 is connected to the ground and is easy to install; and the support frame 12 is located on the back side of the ground and does not affect the daily maintenance and cleaning of the equipment.

[0048] Among them, placing the support frame 12 on the side of the base 11 away from the ground can provide a more stable support structure. Such a design can make the photovoltaic equipment remain stable under the influence of external environment such as wind and sun, and avoid tilting or instability caused by uneven force. Aluminum alloy is used as the material of the support frame 12, which has good corrosion resistance and durability. Aluminum alloy is not easy to rust, and can withstand the erosion of harsh outdoor environment for a long time, extending the service life of the support frame 12. Aluminum alloy has light weight and good strength, making the support frame 12 lighter and easier to carry and install. This not only reduces the installation cost, but also reduces the pressure on the foundation, which is beneficial to the protection and stability of the foundation. Aluminum alloy materials are easy to process and manufacture, and can meet the needs of various shapes and sizes, which is conducive to the production of support frames 12 that meet design requirements, thereby improving production efficiency and product quality.

[0049] More preferably, the base 10 further includes: a photovoltaic base connector 13 .

[0050] The photovoltaic base connector 13 is located on the base 10 and connects and fixes various components of the base 10 .

[0051] Among them, the photovoltaic base connector 13 is located on the base 10, which can connect and fix the various components of the base 10, such as the base 11, the support frame 12, etc. Through the provision of the connector, the various components of the base 10 can be effectively assembled together to form an integral structure, providing stable support and protection. The connector can fix the various components of the base 10, thereby enhancing the overall stability of the photovoltaic base 100. Under the influence of the external environment, the connector can prevent the various components of the photovoltaic base 100 from loosening or shifting, ensuring that the structure of the photovoltaic base 100 is stable and not easily affected by external forces. Through the provision of the connector, maintenance and inspection work on the photovoltaic base 100 can be carried out conveniently. If the photovoltaic base 100 needs to be repaired or parts need to be replaced, it is only necessary to remove the connector to conveniently perform the operation, saving maintenance time and cost.

[0052] Preferably, the central axis of the fixed shaft 20 is an extension line of the fixed shaft 20 passing through the center of a circle, and the centers of the circles are located at the ends of the fixed shaft 20. The direction along the central axis is the axial direction F1. The photovoltaic panel 200 rotates on the fixed shaft 20 around the axial direction F1.

[0053] By aligning the central axis of the fixed shaft 20 as an extension of the center of a circle, with the center of the circle located at each end of the fixed shaft 20, the geometric structure of the fixed shaft 20 is ensured to be symmetrical. This design helps maintain the balance of the photovoltaic panel 200 during rotation, reducing vibration and instability that can result from uneven rotation. Axis F1, defined along the central axis, provides a convenient reference direction, making installation and orientation of the photovoltaic panel 200 simpler and more intuitive. Operators can adjust the rotation angle of the photovoltaic panel 200 based on the direction of axis F1, thereby more accurately capturing solar energy and maximizing the power generation efficiency of the photovoltaic system. The photovoltaic panel 200 rotates around axis F1 on the fixed shaft 20, reducing frictional losses between the panel 200 and the fixed shaft 20. The direction of axis F1 aligns with the rotation direction of the photovoltaic panel 200, helping to minimize rotational resistance, reduce energy loss, and improve the overall efficiency of the photovoltaic system. The configuration of the fixed shaft 200 allows the photovoltaic panel 200 to be flexibly adjusted to maximize solar energy capture. By rotating the photovoltaic panel 200 around the fixed axis 20 along the axial direction F1, it can be ensured that the photovoltaic panel 200 is always in the best light receiving position, thereby improving the power generation efficiency.

[0054] More preferably, the radius of the positioning posts 32 is the same as the radius of the fixed shaft 20, and the distance between the positioning posts 32 is equal to the length of the fixed shaft 20. The distance between the positioning posts 32 is in the axial direction F1, and the length of the fixed shaft 20 is also in the axial direction F1. The fixed shaft 20 is embedded in the arc-shaped groove 31 and is fixed by the positioning posts 32.

[0055] The radius of the positioning posts 32 is the same as that of the fixed shaft 20, and the distance between them matches the length of the fixed shaft 20. This design ensures that the positioning posts 32 can completely enclose the fixed shaft 20 and are evenly distributed between the positioning posts 32. In this way, the fixed shaft 20 can be firmly embedded in the arc-shaped groove 31 and fixed in the correct position by the positioning posts 32, thereby ensuring the stability and safety of the photovoltaic panel 200. The radius of the positioning posts 32 is the same as that of the fixed shaft 20, and the distance between them is evenly distributed along the axial direction F1, which ensures the symmetry of the entire structure. Symmetry is an important factor in ensuring that the photovoltaic panel 200 maintains balance during rotation, reducing vibration and instability caused by asymmetry, and improving the reliability and service life of the photovoltaic system. The design of the positioning posts 32 allows the fixed shaft 20 to be accurately embedded in the arc-shaped groove 31 and fixed in the correct position. This makes installing the photovoltaic panel 200 simpler and more convenient, without the need for additional adjustment or calibration, saving installation time and labor costs.

[0056] A photovoltaic device includes any one of the photovoltaic bases 100 described above, the photovoltaic device also includes a photovoltaic panel 200, and the photovoltaic panel 200 also includes a solar cell 40.

[0057] The solar cell 40 is made of polycrystalline silicon, is located on a side of the back plate 30 away from the fixed axis 20 , is arranged in a square matrix, and is bonded to the back plate 30 .

[0058] Among them, the solar cell 40 is placed on the side of the back plate 30 away from the fixed axis 20, which is conducive to receiving light. This design can ensure that when there is sufficient light during the day, the solar cell 40 can receive sunlight to the greatest extent and convert it into electrical energy, thereby improving the efficiency of photovoltaic power generation. Fixing the solar cell 40 on the back plate 30 can provide additional protection and support, making the cell less susceptible to damage or vibration from the external environment, thereby improving the stability and durability of the photovoltaic equipment. The solar cell 40 is bonded to the back plate 30 in a square array arrangement, which is conducive to installation and maintenance. The square array arrangement makes the spacing between the cells uniform, which is convenient for the installers to arrange and adjust, and also facilitates future maintenance and replacement. The square array layout can make full use of the space on the surface of the back plate 30, maximize the number of solar cells 40, and thus improve the power generation capacity of the photovoltaic system.

[0059] More preferably, the photovoltaic panel 200 further includes a cover plate 50 .

[0060] The cover plate 50 is made of tempered glass and is located on the surface of the solar cell 40 facing away from the back plate 30 . Light passes through the cover plate 50 and enters the interior of the solar cell 40 .

[0061] The cover plate 50 serves as an external covering layer, located on the back of the solar cells 40, effectively protecting them from external environmental damage. Tempered glass offers high hardness and abrasion resistance, protecting the solar cells 40 from damage caused by harsh weather conditions such as wind, rain, and haze, thereby extending their service life. Light passing through the cover plate 50 enters the interior of the solar cells 40, where it is absorbed and converted into electricity. Tempered glass has excellent light transmittance, effectively conducting light and ensuring that it reaches the surface of the solar cells 40, thereby improving the power generation efficiency of the photovoltaic system. The smooth surface of the cover plate 50 is repellent to dust and debris, minimizing the impact of dust on the solar cells 40. This helps keep the solar cells 40 clean, ensuring effective light penetration, and further improving the power generation performance of the photovoltaic system. Tempered glass also offers high strength and pressure resistance, allowing it to withstand certain external impacts, reducing the risk of breakage and damage caused by external collisions or pressure. This helps improve the safety of the photovoltaic system and reduce the possibility of accidents.

[0062] More preferably, the back plate 30 further includes: photovoltaic panel 200 connectors and ventilation and heat dissipation holes 34 .

[0063] The photovoltaic panel 200 connectors connect and fix the various components of the photovoltaic panel 200. The ventilation and heat dissipation holes 34 are circular and located at the edge of the back plate 30. The heat inside the photovoltaic panel 200 is discharged from the photovoltaic panel 200 through the ventilation and heat dissipation holes 34.

[0064] The presence of the photovoltaic panel 200 connectors ensures that the various components of the photovoltaic panel 200 remain stable during installation and operation. The photovoltaic panel 200 is composed of multiple components, such as the solar cells 40, the backsheet 30, and the cover sheet 50. Connecting and securing the components through the connectors can effectively prevent the components from loosening or falling off, thereby improving the overall structural stability of the photovoltaic panel 200. Photovoltaic panels 200 are typically exposed to outdoor environments and are susceptible to wind. Securing the various components through the photovoltaic panel 200 connectors can enhance the wind resistance of the photovoltaic panel 200 and reduce the risk of damage caused by wind. During the operation of the photovoltaic panel 200, components may loosen or vibrate due to factors such as temperature changes and mechanical vibrations. The use of the photovoltaic panel 200 connectors can effectively prevent these problems from occurring, ensuring the stability and reliability of the photovoltaic panel 200. The securing effect of the photovoltaic panel 200 connectors helps reduce friction and wear between the components of the photovoltaic panel 200, thereby extending the service life of the photovoltaic panel 200.

[0065] Among them, the photovoltaic panel 200 absorbs sunlight energy during operation and converts it into electrical energy, but it also generates a certain amount of heat. By setting circular ventilation and heat dissipation holes 34 on the edge of the back plate 30, the heat accumulated inside the photovoltaic panel 200 can be effectively discharged to prevent overheating from having adverse effects on the photovoltaic panel 200, such as reducing power generation efficiency or shortening component life. Placing the ventilation and heat dissipation holes 34 at the edge position can make the heat dissipation more uniform. The edge position is more likely to accumulate heat than the center of the photovoltaic panel 200. By setting ventilation holes at these positions, air can flow more effectively across the entire surface of the photovoltaic panel 200, achieving a more uniform heat dissipation effect. Setting ventilation holes at the edge of the back plate 30 will not have too much impact on the structural stability of the photovoltaic panel 200. Compared with setting ventilation holes at the center position, the edge position is more suitable for reducing the loss of structural strength and can effectively avoid affecting the aesthetics of the photovoltaic panel 200.

[0066] In this way, the photovoltaic panel 200 is rotated on the fixed shaft 20 to adjust the direction of the photovoltaic panel 200, thereby improving the power generation efficiency, and the magnetic sheet 21 on the positioning column 32 is attracted to the magnetic sheet 21 at both ends of the fixed shaft 20, and the arc-shaped groove 31 is embedded in the fixed shaft 20, thereby improving the convenience of installation.

[0067] The above-described embodiments merely represent several embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
