Description

Technical Field

[0001] This application relates to the field of solar energy technology, and in particular to a photovoltaic system with an eccentric shaft support and its photovoltaic bracket. Background Technology

[0002] In the prior art, photovoltaic systems may include photovoltaic panel modules and panel support modules. Photovoltaic panel modules are primarily used to convert solar energy or light energy into electrical energy. Panel support modules support the photovoltaic panel modules and can adjust the orientation of the photovoltaic panel modules to receive light energy at an appropriate angle. It is understood that the panel support module includes a main beam. The main beam has a center of rotation, which drives the panel support module to rotate, thereby further causing the orientation of the photovoltaic panel modules to change.

[0003] In the process of developing the existing technology, the inventors discovered that: The distance between the center of gravity of the panel support assembly (excluding the panel support assembly itself) and the center of rotation of the main beam is the first lever arm. Simultaneously, the distance between the center of gravity of the photovoltaic panel assembly and the center of rotation of the main beam is the second lever arm. When the orientation of the photovoltaic panel assembly changes, other components of the panel support assembly generate a resisting torque with the first lever arm, and the photovoltaic panel assembly generates a resisting torque with the second lever arm. The photovoltaic system needs to overcome these resisting torques to rotate. This places demands on the torsional strength of the main beam, and also results in energy loss due to overcoming the resisting torques during rotation.

[0004] Therefore, there is a need to provide an energy-saving technical solution for photovoltaic systems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please refer to Figures 1 to 4 This application discloses a photovoltaic system 100 with an eccentric support, comprising: Photovoltaic panel module 11 is used to convert light energy into electrical energy; The panel support assembly 12 is used to support the photovoltaic panel assembly 11 and can adjust the orientation of the photovoltaic panel assembly 11 so as to receive light energy at an appropriate angle. Support component 13 is used to support the panel support component 12 at a preset height above the ground; The support component 13 includes: Support leg 131; Mounting base 132 installed at the top of support leg 131; A first receiving bracket 133 fitted into the mounting base 132 and a second receiving bracket 134 arranged asymmetrically with respect to the first receiving bracket 133; The panel support assembly 12 includes a main beam 121; The first receiving bracket 133 engages with one side of the main beam 121; The second support 134 is fastened to the main beam 121 from the opposite side of the main beam 121; The first support 133 and the second support 134 circumferentially limit the main beam 121 so that the main beam 121 can rotate. The main beam 121 is installed via the first support bracket 133 and the second support bracket 134, and has a rotation center X; The mounting base 132 has a mounting center Y; The distance from the X-center of rotation to the ground is less than the distance from the Y-center of installation to the ground.

[0020] A photovoltaic (PV) panel module 11 is used to convert light energy into electrical energy. The PV panel module 11 can be primarily made of polycrystalline silicon or monocrystalline silicon, or other semiconductor materials with photoelectric effects. Sunlight shines on the PV panel module 11 and is absorbed at its interface layer. The PV panel module 11, made of semiconductor materials, has a PN junction. Photons of sufficient energy in the absorbed sunlight can excite electrons in the PN junction from their covalent bonds, resulting in electron-hole pairs. Before recombination, the electrons and holes near the interface layer are separated by the electric field of the space charge. This charge separation at the interface layer generates a measurable outward voltage across the PN junction. The more electron-hole pairs generated at the interface layer of the PV panel module 11 by sunlight, the greater the current. The more light energy absorbed by the interface layer of the PV panel module 11, and the larger the area of ​​the interface layer (i.e., the irradiated area of ​​the PV panel module 11), the greater the current generated by the PV panel module 11. The current generated by the PV panel module 11 can be collected through a busbar and used as a power source.

[0021] The panel support assembly 12 is used to support the photovoltaic panel assembly 11 and can adjust the orientation of the photovoltaic panel assembly 11 so as to receive light energy at an appropriate angle.

[0022] The panel support assembly 12 includes a main beam 121, purlins 122 mounted on the main beam 121, and secondary beams.

[0023] The main beam 121 rotates and has a rotation center X.

[0024] The secondary beam can be mounted on the purlin 122 or fixedly connected to the purlin 122 in the same plane. The photovoltaic panel module 11 can be directly mounted and fixed to the secondary beam.

[0025] Support component 13 includes: Support leg 131; Mounting base 132 installed at the top of support leg 131; A first support bracket 133 fitted into the mounting base 132 and a second support bracket 134 arranged asymmetrically with respect to the first support bracket 133.

[0026] The support component 13 supports the panel support component 12 at a preset height off the ground. The preset height can be set as needed, which on the one hand facilitates the rotation of the panel support component 12, and on the other hand leaves sufficient height redundancy below the panel support component 12 to meet other needs, such as the walking of livestock.

[0027] The support leg 131 is mainly used to provide support for the support panel support assembly 12. The support leg 131 can extend to provide a fixed foot. The fixed foot can be fixed to the ground in various ways. In the preferred embodiment provided in this application, in order to strengthen the support structure, the fixed foot can be partially buried underground, with only the exposed part used to connect the support leg 131. The fixed foot can be a concrete block, a metal block, or made of other materials or composite materials.

[0028] Mounting base 132 is disposed at the top of support leg 131. Mounting base 132 may extend integrally to support leg 131, or it may be fixedly connected or welded to support leg 131. Mounting base 132 is mainly used to mount main beam 121, thereby supporting panel support assembly 12. Mounting base 132 has mounting center Y.

[0029] A first receiving bracket 133 and a second receiving bracket 134, asymmetrically arranged with respect to the first receiving bracket 133, are fitted into a mounting base 132. The first receiving bracket 133 engages one side of the main beam 121. The second receiving bracket 134 engages the main beam 121 from a opposite side away from one side of the main beam 121. The first receiving bracket 133 and the second receiving bracket 134 circumferentially define the main beam 121 to allow rotation of the main beam 121. The main beam 121 is mounted via the first receiving bracket 133 and the second receiving bracket 134 and has a center of rotation X.

[0030] The distance from the rotation center X to the ground is less than the distance from the installation center Y to the ground. This reduces the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11, thereby reducing the energy consumption of rotating the panel support assembly 12 and the photovoltaic panel assembly 11.

[0031] Please refer to Figure 4 In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The first arc-shaped portion and the second arc-shaped portion have the same radius of curvature and arc length; The depth of the first settling tank 1331 is greater than the depth of the second settling tank 1341.

[0032] The first support 133 is used to support the main beam 121. The first support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion. The cross-section of the first support 133 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0033] The second support 134 is also used to support the main beam 121. Compared with the first support 133, the main function of the second support 134 is to limit rather than support. The second support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion. The cross-section of the second support 134 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0034] In other words, during the rotation of the main beam 121, most of the lifting force is borne by the first support bracket 133. In actual use, the first support bracket 133 is closer to the ground than the second support bracket 134.

[0035] The first and second arc-shaped portions have the same radius of curvature and arc length. In other words, the first and second arc-shaped portions can be fitted into the same circle, and there is an installation gap between them. Furthermore, to use the same fixture and reduce production costs, the arc lengths of the first and second arc-shaped portions are the same. The only difference is that the depth of the first sink 1331 is greater than the depth of the second sink 1341. This causes the rotation center X of the main beam 121 to shift downwards, thereby shifting the center of gravity of the panel support assembly 12 and the photovoltaic panel assembly 11 downwards, reducing the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11. This reduces the driving torque required to rotate the panel support assembly 12 and the photovoltaic panel assembly 11, achieving energy-saving effects.

[0036] In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The first arc-shaped portion and the second arc-shaped portion have the same radius of curvature; The arc length of the first arc-shaped portion is smaller than the arc length of the second arc-shaped portion; The depth of the first settling tank 1331 is equal to the depth of the second settling tank 1341.

[0037] The first support 133 is used to support the main beam 121. The first support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion. The cross-section of the first support 133 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0038] The second support 134 is also used to support the main beam 121. Compared with the first support 133, the main function of the second support 134 is to limit rather than support. The second support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion. The cross-section of the second support 134 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0039] In other words, during the rotation of the main beam 121, most of the lifting force is borne by the first support bracket 133. In actual use, the first support bracket 133 is closer to the ground than the second support bracket 134.

[0040] The first and second arc-shaped portions have the same radius of curvature. In other words, the first and second arc-shaped portions can fit into the same circle, and there is an installation gap between them. The arc length of the first arc-shaped portion is less than that of the second arc-shaped portion. The depth of the first recess 1331 is equal to the depth of the second recess 1341. This causes the rotation center X of the main beam 121 to shift downwards, thereby lowering the center of gravity of the panel support assembly 12 and the photovoltaic panel assembly 11, reducing the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11. Consequently, the driving torque required to rotate the panel support assembly 12 and the photovoltaic panel assembly 11 is reduced, achieving energy-saving effects.

[0041] Please refer to Figure 4 In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The cross-section of the first settling tank 1331 is rectangular; The cross-section of the second settling tank 1341 is rectangular.

[0042] In one specific implementation provided in this application, the main beam 121 is made of square steel. The first sinker 1331 has a rectangular cross-section. The second sinker 1341 has a rectangular cross-section. In this way, the main beam 121 is securely installed with the first support 133 and the second support 134, and at the same time, the first support 133 and the second support 134 can conveniently support the main beam 121.

[0043] Please refer to Figure 4 In one specific embodiment provided in this application, the first receiving support 133 and / or the second receiving support 134 have guide walls 1330.

[0044] The first receiving bracket 133 has a guide wall 1330. That is, the radius of the outer surface of the first arc-shaped portion of the first receiving bracket 133 is smaller than the radius of the middle portion of the first arc-shaped portion. When the first receiving bracket 133 is fitted into the mounting base 132, tapping from the side opposite to where the guide wall 1330 is provided on the first receiving bracket 133 will cause the first receiving bracket 133 to fit into the mounting base 132. When the first receiving bracket 133 is worn and needs to be replaced, tapping from the side where the guide wall 1330 is provided on the first receiving bracket 133 will cause the first receiving bracket 133 to detach from the mounting base 132.

[0045] The second receiving bracket 134 may also be provided with a guide wall 1330. That is, the radius of the outer surface of the second arc-shaped portion of the second receiving bracket 134 is smaller than the radius of the middle portion of the two arc-shaped portions. When the second receiving bracket 134 is fitted into the mounting base 132, tapping from the side opposite to where the guide wall 1330 is provided on the second receiving bracket 134 will cause the second receiving bracket 134 to fit into the mounting base 132. When the second receiving bracket 134 is worn and needs to be replaced, tapping from the side where the guide wall 1330 is provided on the second receiving bracket 134 will cause the second receiving bracket 134 to detach from the mounting base 132.

[0046] This application also provides a photovoltaic bracket with an eccentric bearing, comprising: The panel support assembly 12 is used to support the photovoltaic panel assembly 11 and can adjust the orientation of the photovoltaic panel assembly 11 so as to receive light energy at an appropriate angle. Support component 13 is used to support the panel support component 12 at a preset height above the ground; The support component 13 includes: Support leg 131; Mounting base 132 installed at the top of support leg 131; A first receiving bracket 133 fitted into the mounting base 132 and a second receiving bracket 134 arranged asymmetrically with respect to the first receiving bracket 133; The panel support assembly 12 includes a main beam 121; The first receiving bracket 133 engages with one side of the main beam 121; The second support 134 is fastened to the main beam 121 from the opposite side of the main beam 121; The first support 133 and the second support 134 circumferentially limit the main beam 121 so that the main beam 121 can rotate. The main beam 121 is installed via the first support bracket 133 and the second support bracket 134, and has a rotation center X; The mounting base 132 has a mounting center Y; The distance from the X-center of rotation to the ground is less than the distance from the Y-center of installation to the ground.

[0047] The part of the photovoltaic system 100 with eccentric bearing after the photovoltaic panel module 11 has been removed can be understood as the photovoltaic support here.

[0048] The panel support assembly 12 is used to support the photovoltaic panel assembly 11 and can adjust the orientation of the photovoltaic panel assembly 11 so as to receive light energy at an appropriate angle.

[0049] The panel support assembly 12 includes a main beam 121, purlins 122 mounted on the main beam 121, and secondary beams.

[0050] The main beam 121 rotates and has a rotation center X.

[0051] The secondary beam can be mounted on the purlin 122 or fixedly connected to the purlin 122 in the same plane. The photovoltaic panel module 11 can be directly mounted and fixed to the secondary beam.

[0052] Support component 13 includes: Support leg 131; Mounting base 132 installed at the top of support leg 131; A first support bracket 133 fitted into the mounting base 132 and a second support bracket 134 arranged asymmetrically with respect to the first support bracket 133.

[0053] The support component 13 supports the panel support component 12 at a preset height off the ground. The preset height can be set as needed, which on the one hand facilitates the rotation of the panel support component 12, and on the other hand leaves sufficient height redundancy below the panel support component 12 to meet other needs, such as the walking of livestock.

[0054] The support leg 131 is mainly used to provide support for the support panel support assembly 12. The support leg 131 can extend to provide a fixed foot. The fixed foot can be fixed to the ground in various ways. In the preferred embodiment provided in this application, in order to strengthen the support structure, the fixed foot can be partially buried underground, with only the exposed part used to connect the support leg 131. The fixed foot can be a concrete block, a metal block, or made of other materials or composite materials.

[0055] Mounting base 132 is disposed at the top of support leg 131. Mounting base 132 may extend integrally to support leg 131, or it may be fixedly connected or welded to support leg 131. Mounting base 132 is mainly used to mount main beam 121, thereby supporting panel support assembly 12. Mounting base 132 has mounting center Y.

[0056] A first receiving bracket 133 and a second receiving bracket 134, asymmetrically arranged with respect to the first receiving bracket 133, are fitted into a mounting base 132. The first receiving bracket 133 engages one side of the main beam 121. The second receiving bracket 134 engages the main beam 121 from a opposite side away from one side of the main beam 121. The first receiving bracket 133 and the second receiving bracket 134 circumferentially define the main beam 121 to allow rotation of the main beam 121. The main beam 121 is mounted via the first receiving bracket 133 and the second receiving bracket 134 and has a center of rotation X.

[0057] The distance from the rotation center X to the ground is less than the distance from the installation center Y to the ground. This reduces the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11, thereby reducing the energy consumption of rotating the panel support assembly 12 and the photovoltaic panel assembly 11.

[0058] In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The first arc-shaped portion and the second arc-shaped portion have the same radius of curvature and arc length; The depth of the first settling tank 1331 is greater than the depth of the second settling tank 1341.

[0059] The first support 133 is used to support the main beam 121. The first support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion. The cross-section of the first support 133 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0060] The second support 134 is also used to support the main beam 121. Compared with the first support 133, the main function of the second support 134 is to limit rather than support. The second support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion. The cross-section of the second support 134 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0061] In other words, during the rotation of the main beam 121, most of the lifting force is borne by the first support bracket 133. In actual use, the first support bracket 133 is closer to the ground than the second support bracket 134.

[0062] The first and second arc-shaped portions have the same radius of curvature and arc length. In other words, the first and second arc-shaped portions can be fitted into the same circle, and there is an installation gap between them. Furthermore, to use the same fixture and reduce production costs, the arc lengths of the first and second arc-shaped portions are the same. The only difference is that the depth of the first sink 1331 is greater than the depth of the second sink 1341. This causes the rotation center X of the main beam 121 to shift downwards, thereby shifting the center of gravity of the panel support assembly 12 and the photovoltaic panel assembly 11 downwards, reducing the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11. This reduces the driving torque required to rotate the panel support assembly 12 and the photovoltaic panel assembly 11, achieving energy-saving effects.

[0063] In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The first arc-shaped portion and the second arc-shaped portion have the same radius of curvature; The arc length of the first arc-shaped portion is smaller than the arc length of the second arc-shaped portion; The depth of the first settling tank 1331 is equal to the depth of the second settling tank 1341.

[0064] The first support 133 is used to support the main beam 121. The first support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion. The cross-section of the first support 133 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0065] The second support 134 is also used to support the main beam 121. Compared with the first support 133, the main function of the second support 134 is to limit rather than support. The second support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion. The cross-section of the second support 134 can be understood as being formed by an arc at one end and a chord that cuts off the arc, with the chord sinking at approximately the middle position to form the recess.

[0066] In other words, during the rotation of the main beam 121, most of the lifting force is borne by the first support bracket 133. In actual use, the first support bracket 133 is closer to the ground than the second support bracket 134.

[0067] The first and second arc-shaped portions have the same radius of curvature. In other words, the first and second arc-shaped portions can fit into the same circle, and there is an installation gap between them. The arc length of the first arc-shaped portion is less than that of the second arc-shaped portion. The depth of the first recess 1331 is equal to the depth of the second recess 1341. This causes the rotation center X of the main beam 121 to shift downwards, thereby lowering the center of gravity of the panel support assembly 12 and the photovoltaic panel assembly 11, reducing the resistance torque of the panel support assembly 12 and the photovoltaic panel assembly 11. Consequently, the driving torque required to rotate the panel support assembly 12 and the photovoltaic panel assembly 11 is reduced, achieving energy-saving effects.

[0068] In one specific embodiment provided in this application, the first receiving support 133 includes a first arc-shaped portion and a first recess 1331 formed by the recess of the first arc-shaped portion; The second receiving support 134 includes a second arc-shaped portion and a second recess 1341 formed by the indentation of the second arc-shaped portion; The cross-section of the first settling tank 1331 is rectangular; The cross-section of the second settling tank 1341 is rectangular.

[0069] In one specific implementation provided in this application, the main beam 121 is made of square steel. The first sinker 1331 has a rectangular cross-section. The second sinker 1341 has a rectangular cross-section. In this way, the main beam 121 is securely installed with the first support 133 and the second support 134, and at the same time, the first support 133 and the second support 134 can conveniently support the main beam 121.

[0070] In one specific embodiment provided in this application, the first receiving support 133 and / or the second receiving support 134 have guide walls 1330.

[0071] The first receiving bracket 133 has a guide wall 1330. That is, the radius of the outer surface of the first arc-shaped portion of the first receiving bracket 133 is smaller than the radius of the middle portion of the first arc-shaped portion. When the first receiving bracket 133 is fitted into the mounting base 132, tapping from the side opposite to where the guide wall 1330 is provided on the first receiving bracket 133 will cause the first receiving bracket 133 to fit into the mounting base 132. When the first receiving bracket 133 is worn and needs to be replaced, tapping from the side where the guide wall 1330 is provided on the first receiving bracket 133 will cause the first receiving bracket 133 to detach from the mounting base 132.

[0072] The second receiving bracket 134 may also be provided with a guide wall 1330. That is, the radius of the outer surface of the second arc-shaped portion of the second receiving bracket 134 is smaller than the radius of the middle portion of the two arc-shaped portions. When the second receiving bracket 134 is fitted into the mounting base 132, tapping from the side opposite to where the guide wall 1330 is provided on the second receiving bracket 134 will cause the second receiving bracket 134 to fit into the mounting base 132. When the second receiving bracket 134 is worn and needs to be replaced, tapping from the side where the guide wall 1330 is provided on the second receiving bracket 134 will cause the second receiving bracket 134 to detach from the mounting base 132.
