[0051] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0052] The principle of the photovoltaic support 100 proposed in the present application, which can achieve the beneficial effects described above, is described in detail as follows:

[0053] In the related art, as shown in Figure 1 , the photovoltaic assembly 200 is installed on the upper part of the main shaft 120, and there is a certain deviation between the center of gravity O of the photovoltaic assembly 200 and the rotation center O1 of the main shaft 120. In the working process of the photovoltaic support 100, the photovoltaic assembly 200 rotates with the sun, and the gravity G of the photovoltaic support 100 and the rotation center O1 exist a force arm h, the photovoltaic support 100 will produce an eccentric torque M, and the eccentric torque M increases with the increase of the rotation angle of the main shaft 120. The existence of the eccentric torque will produce additional power loss, which will cause the driving system to require larger motor power. On the other hand, when the photovoltaic support 100 is in a strong wind condition, the photovoltaic support 100 will be affected by the wind force to produce a certain degree of vibration, causing impact damage.

[0054] In order to solve the technical problem, the present application provides a photovoltaic support 100, which is described below with reference to Figures 1-6 the photovoltaic support 100 according to the embodiments of the present application.

[0055] As shown in Figure 2 and Figure 3 , the photovoltaic support 100 of the embodiments of the present application comprises a stand 110, a main shaft 120, a force transmitting member 130 and an elastic member 140.

[0056] The column 110 is fixed to the ground, which can be fixed to the ground by concrete pouring, anchor bolts, chemical anchoring agent or other mechanical anchoring system.

[0057] The column 110 can be made of aluminum alloy, stainless steel, hot-dip galvanized steel, composite materials and the like. For steel column 110, the structural strength of the fixed structure can be improved by adding reinforcing ribs or using thicker steel plates.

[0058] The cross section of the column 110 can be circular, rectangular, triangular or polygonal, and can also be customized according to specific installation requirements and design requirements.

[0059] The main shaft 120 is installed on the column 110, and the main shaft 120 is used to install the photovoltaic module 200, and the photovoltaic module 200 and the main shaft 120 will rotate together on the column 110.

[0060] The main shaft 120 is usually made of aluminum alloy material, which has high strength and stiffness, and also has good corrosion resistance and processing performance.

[0061] The main shaft 120 can be a single shaft, or a combination of several unit shaft sleeves.

[0062] The main shaft 120 is usually an octagonal pipe or an octagonal pipe, which can reduce the amount of material under the same bending strength, and has good torsional strength.

[0063] Through the installation of the column 110 and the main shaft 120, the elastic member 140, the force transmission member 130 and the photovoltaic module 200 can be installed and positioned.

[0064] The force transmission member 130 is connected to the main shaft 120, and the force transmission member 130 and the main shaft 120 are detachably connected or non-detachably connected.

[0065] The force transmission member 130 can be installed on the main shaft 120 on one side or both sides, and when the force transmission member 130 is installed on the main shaft 120 on both sides, the force transmission member 130 has a first stress position and a second stress position on both sides of the main shaft 120, and the force transmission member 130 is installed on one side or both sides of the main shaft 120. The torque opposite to the eccentric torque is offset.

[0066] The elastic member 140 is elastically connected between the force transmission member 130 and the column 110, that is, one end of the elastic member 140 is connected to the end of the force transmission member 130 away from the main shaft 120, and the other end of the elastic member 140 is connected to the column 110.

[0067] Since the force transmission member 130 can be installed on the main shaft 120 on one side or both sides, the elastic member 140 can also be connected between the force transmission member 130 and the column 110 on one side or both sides.

[0068] When the force transferring piece 130 is single-sidedly mounted on the main shaft 120, the elastic piece 140 is single-sidedly connected between the force transferring piece 130 and the stand column 110; when the force transferring piece 130 is double-sidedly mounted on the main shaft 120, the elastic piece 140 is double-sidedly connected between the force transferring piece 130 and the stand column 110.

[0069] When the photovoltaic module 200 is tilted towards a first direction, the elastic piece 140 applies a torque opposite to the first direction to the main shaft 120 through the force transferring piece 130, the first direction can be clockwise rotation around the rotation center of the main shaft 120, or the first direction can be counterclockwise rotation around the rotation center of the main shaft 120.

[0070] Through the elastic connection between the elastic piece 140 and the force transferring piece 130, a torque opposite to the eccentric torque of the photovoltaic module 200 is generated on the force transferring piece 130 to offset the eccentric torque.

[0071] It should be noted that the photovoltaic module 200 is the core part of the photovoltaic system, which is made through the steps of series and parallel connection of cell pieces, encapsulation, etc., and can convert solar energy into electrical energy.

[0072] After the photovoltaic module 200 and the force transferring piece 130 of the embodiment of the present application are both mounted on the main shaft 120, the elastic piece 140 is elastically connected between the force transferring piece 130 and the stand column 110. When the photovoltaic module 200 rotates with the sun or is blown by the wind, because the rotation center O1 of the photovoltaic module 200 and the main shaft 120 does not coincide, a torque is formed between the center of gravity O of the photovoltaic module 200 and the rotation axis of the main shaft 120 when the photovoltaic module 200 is deflected, thereby generating an eccentric torque. At this time, the elastic piece 140 will provide a torque in the opposite direction to offset it, and the elastic piece 140 will reduce the vibration impact.

[0073] According to the photovoltaic support 100 provided by the embodiment of the present application, by connecting the force transferring piece 130 and the elastic piece 140 on the main shaft 120, a torque opposite to the eccentric torque of the photovoltaic module 200 is generated, which can offset the eccentric torque, reduce the power generation power loss, improve the power generation efficiency, and at the same time, the elastic piece 140 can absorb the vibration and reduce the impact of the vibration.

[0074] In some embodiments, as shown in Figure 3 The force transferring piece 130 has a first force receiving position and a second force receiving position located on both sides of the main shaft 120 respectively.

[0075] The elastic piece 140 includes a first elastic piece 141 and a second elastic piece 142.

[0076] The first elastic piece 141 is elastically connected between the first force receiving position and the stand column 110; the second elastic piece 142 is elastically connected between the second force receiving position and the stand column 110.

[0077] The first elastic member 141 and the second elastic member 142 are symmetrically arranged about the plane in which the axis of the main shaft 120 lies.

[0078] The first elastic member 141 and the second elastic member 142 are of the same specifications, including size, mass, elastic coefficient, etc.

[0079] In the case where the photovoltaic module 200 is tilted towards the side where the first force position is located, the first elastic member 141 applies an upward force to the first force position; in the case where the photovoltaic module 200 is tilted towards the side where the second force position is located, the second elastic member 142 applies an upward force to the second force position.

[0080] In actual working process, in the case where the photovoltaic module 200 is tilted towards the side where the first force position is located, the first elastic member 141 applies an upward force to the first force position, while the second elastic member 142 applies a downward force to the second force position, forming a torque; in the case where the photovoltaic module 200 is tilted towards the side where the second force position is located, the second elastic member 142 applies an upward force to the second force position, while the first elastic member 141 applies a downward force to the first force position, forming a torque.

[0081] In some embodiments, as shown in FIG. 1, the force transmission member 130 includes a connecting member 131 and a force transmission arm 132. Figure 3

[0082] The connecting member 131 is installed on the main shaft 120.

[0083] The force transmission arm 132 is connected to the connecting member 131, and one end of the force transmission arm 132, which is away from the connecting member 131, is connected to the elastic member 140, i.e., one end of the force transmission arm 132 is connected to the connecting member 131, and the other end of the force transmission arm 132, which is away from the connecting member 131, is connected to the elastic member 140.

[0084] The force transmission arm 132 needs to have sufficient strength and rigidity to withstand the transmitted force. Commonly used materials for the force transmission arm 132 include high-strength steel and alloy steel, such as 45 steel or 42CrMo steel. When selecting the material for the force transmission arm 132, it is also necessary to consider that it should have good durability to resist long-term wear and fatigue. Alloy steel is often chosen to make the force transmission arm 132 due to its excellent fatigue performance and wear resistance.

[0085] The connecting member 131 and the force transmission arm 132 can be made of the same material, or they can be made of different materials.

[0086] The connecting member 131 can connect the force transmission arm 132 to the main shaft 120 and make it rotate with the main shaft 120.

[0087] In some embodiments, as shown in FIG. 1, the force transmission member 130 includes a connecting member 131 and a force transmission arm 132. Figure 3 ​As shown, the connecting member 131 can be at least one of the following structural forms:

[0088] First, the connecting member 131 includes a first hoop 1311 and a second hoop 1312.

[0089] In this embodiment, the first hoop 1311 and the second hoop 1312 are respectively arranged on both sides of the main shaft 120, and can be connected between the first hoop 1311 and the second hoop 1312. After the first hoop 1311 and the second hoop 1312 are connected, they encircle the main shaft 120.

[0090] The first hoop 1311 and the second hoop 1312 can be made of carbon steel, alloy steel, stainless steel, cast iron, aluminum alloy, spring steel, and hard alloy.

[0091] By connecting the first hoop 1311 and the second hoop 1312, it is convenient to disassemble, and it can be connected on one side or on both sides.

[0092] By connecting the first hoop 1311 and the second hoop 1312 around the main shaft 120, the two hoops can provide more stable connection, especially when bearing transverse load or torsional force, which can increase the strength of the connection point, bear greater load, and through the first hoop 1311 and the second hoop 1312, the load can be more evenly distributed in the connection area, reducing stress concentration. If one of the first hoop 1311 or the second hoop 1312 fails, the other can serve as a backup to provide additional safety.

[0093] Second, the connecting member 131 is a hoop.

[0094] In this embodiment, the inner circle of the hoop is matched with the main shaft 120, and the outer circle is connected with the force arm 132.

[0095] The hoop can be made of the same materials as the first hoop 1311 and the second hoop 1312 described above.

[0096] The hoop can significantly improve the stability and carrying capacity of the structural components, especially when bearing pressure and shear force, and the hoop can also prevent local buckling and increase overall stability.

[0097] Third, the connecting member 131 is a sleeve.

[0098] In this embodiment, the sleeve is sleeved on the main shaft 120, and the outer surface is connected with the force arm 132.

[0099] The sleeve can be made of the same materials as the first hoop 1311, the second hoop 1312, and the hoop described above.

[0100] The sleeve can protect the main shaft 120 from wear and tear, prolong the service life of the main shaft 120, provide additional strength and stiffness, facilitate disassembly and installation, and also accurately position and center the main shaft 120, ensuring correct installation and operation of the main shaft 120.

[0101] The force transmission arm 132 is connected to the main shaft 120 through the connecting piece 131, facilitating rotation with the main shaft 120.

[0102] In some embodiments, as shown in Figure 3 The photovoltaic support 100 of the present application also includes a base 150.

[0103] The base 150 is installed on the column 110, and the end of the elastic member 140 away from the force transmission member 130 is connected to the base 150.

[0104] The base 150 is used to fix the elastic member 140 on the column 110.

[0105] It should be noted that the base 150 is installed on the column 110, and the end of the elastic member 140 away from the force transmission arm 132 of the force transmission member 130 is connected to the base 150.

[0106] By fixing the elastic member 140 on the column 110 through the base 150, better stability can be provided, reducing vibration and displacement, improving the overall carrying capacity, and also allowing quick installation and disassembly, facilitating maintenance and replacement of the photovoltaic support 100.

[0107] In some embodiments, as shown in Figure 3 The base 150 includes a seat body 151 and an extension piece 152.

[0108] The seat body 151 is installed on the column 110, and the extension piece 152 is used in cooperation with the seat body 151 to connect the elastic member 140 to the column 110.

[0109] For example, one side of the plate-shaped seat body 151 is attached to the column 110 and is fixed to the column 110 by bolts.

[0110] The seat body 151 can be made of various materials, including cast iron, steel, aluminum alloy, or other engineering plastics.

[0111] The extension piece 152 can be more stably installed by installing the seat body 151.

[0112] The extension piece 152 is connected to the seat body 151 and extends towards the axis of the main shaft 120, and the end of the elastic member 140 away from the force transmission member 130 is connected to the end of the extension piece 152 away from the column 110.

[0113] One end of the extension 152 is connected to the base 151, and the extension direction is parallel to the axis of the main shaft 120.

[0114] One end of the elastic element 140 away from the force transmission arm 132 of the force transmission element 130 is connected to the end of the extension element 152 away from the column 110.

[0115] The extension 152 can be made of the same material as the base 151.

[0116] The extension 152 can be a column with a cross-sectional shape such as a circular cross-section, a rectangular cross-section, or an I-beam.

[0117] In some embodiments, such as Figure 3 As shown, the distance from the end of the elastic element 140 connected to the force transmission element 130 to the target plane is greater than the distance from the end of the elastic element 140 connected to the base 150 to the target plane.

[0118] The distance from the end of the elastic element 140 connected to the force transmission element 130 to the target plane is the torque arm. The longer the arm, the smaller the force required to produce the same rotational effect.

[0119] The target plane is a vertical plane and the axis of the main axis 120 is located within the target plane.

[0120] It should be noted that the extension direction of the elastic element 140 is perpendicular to the axis of the main shaft 120.

[0121] In some embodiments, the elastic element 140 may be at least one of the following structural forms:

[0122] Firstly, such as Figure 3 As shown, the elastic element 140 is a spring rod.

[0123] The photovoltaic bracket 100 is described below using a spring rod as the elastic element 140.

[0124] In this embodiment, the elastic element 140 is a spring rod of the same specification. The spring rods have the same specifications, including the same spring size, mass, and spring constant.

[0125] The base 150 is mounted on the column 110 and remains stationary during the operation of the photovoltaic bracket 100. The base 150 has an extension 152 parallel to the main shaft 120 for connecting two spring rods. The force transmission arm 132 is mounted on the main shaft 120 via a first clamp 1311 and a second clamp 1312, and rotates as the main shaft 120 rotates. Each column 110 is equipped with the aforementioned photovoltaic bracket 100.

[0126] The force transmission arm 132 and the spring rod are hinged.

[0127] For example, the force transmission arm 132 and the spring rod can be hingedly connected or ball-joint connected.

[0128] The hinged connection of the force transmission arm 132 and the spring rod can allow the force transmission arm 132 and the spring rod to freely rotate on a predetermined axis, provide necessary movement flexibility, prevent unnecessary movement or distortion, generally withstand large loads, reduce friction and wear between components, and facilitate inspection and replacement.

[0129] At this time, the spring rod and the extension piece 152 can also be hingedly connected.

[0130] When the photovoltaic module 200 vibrates under strong wind conditions, the spring rod can absorb and reduce the vibration and impact, protecting the photovoltaic module 200 from damage.

[0131] When the photovoltaic module 200 is in a horizontal position, as shown in Figure 2 , the photovoltaic support 100 at this time is in a balanced state, the center of gravity O of the photovoltaic module 200 and the rotation center O1 of the main shaft 120 are on the same vertical line, and no eccentric torque is generated.

[0132] At this time, the two spring rods are symmetrically distributed on the left and right sides of the main shaft 120, and the spring is in a natural state, i.e., the spring is in an original length without being stretched or compressed. In this state, there is no stress or strain inside the spring, and no potential energy is stored.

[0133] When the photovoltaic module 200 is at a certain angle of inclination with respect to the horizontal plane, as shown in Figure 4 , the center of gravity O of the photovoltaic module 200 and the rotation center O1 of the main shaft 120 are not on the same straight line, and a certain eccentric torque M is generated.

[0134] One of the two spring rods is compressed to generate a spring force F1, and the other spring rod is stretched to generate a tensile force F2. The two spring rods will generate a certain torque M1 on the main shaft 120 through the force transmission arm 132, and the torque M1 is opposite in direction to the eccentric torque M generated by the photovoltaic module 200, and can to some extent offset the influence of the eccentric torque M on the photovoltaic support 100.

[0135] The spring itself has a vibration-absorbing effect. When the photovoltaic module 200 vibrates, the spring can absorb and release energy, thereby reducing the amplitude and frequency of vibration. At the same time, the spring rod can provide a different vibration frequency, which is staggered with the resonance frequency of the photovoltaic module 200, so that resonance phenomenon can be avoided.

[0136] It should be noted that the spring can be replaced by an energy storage device such as a compression spring.

[0137] Secondly, as shown in Figure 6 , the elastic member 140 is a spring damper.

[0138] The spring damper is used as the elastic member 140 in the following description of the photovoltaic support 100.

[0139] In this embodiment, the spring damper is used instead of the spring rod, which can absorb and reduce the energy of vibration, achieve the function of vibration reduction, and reduce the amplitude and frequency of support vibration.

[0140] The force transmission arm 132 and the spring damper can be connected through a connecting ring.

[0141] At this time, the spring damper and the extension member 152 can also be connected through a connecting ring.

[0142] The connecting ring is usually made of high-strength materials such as steel, stainless steel or alloy, which can withstand high load and repeated use, and is not easy to break or deform.

[0143] The force transmission arm 132 and the spring damper are connected through the connecting ring, providing flexibility in installation and use, and can easily adjust the direction as needed. The ring structure is compact and occupies less space. The use and installation of the connecting ring are usually simple and do not require complex mechanical devices or tools. The connecting ring can reduce direct friction between the force transmission arm 132 and the spring damper, thereby reducing wear.

[0144] It should be noted that the spring damper absorbs impact and vibration energy through the elastic deformation of the spring, and the damping material consumes energy through internal friction, converting kinetic energy into heat energy.

[0145] The spring damper can be selected from a compression spring damper, a tension spring damper, a shear spring damper and a composite spring damper.

[0146] The spring is usually made of metal, such as carbon steel, stainless steel or alloy steel.

[0147] The damping material can be a viscoelastic material, hydraulic oil or other special materials for increasing internal friction and improving energy dissipation efficiency. The damper can also be replaced by a shock absorber, which provides a reverse force to reduce movement when subjected to impact or vibration.

[0148] Thirdly, the elastic member 140 is a gas cylinder.

[0149] In this embodiment, the gas cylinder is a gas cylinder with a spring return function, which is used to push the piston back to its original position after the gas cylinder releases pressure. The gas cylinder uses compressed air to generate force and can provide a reverse force as a pressure element.

[0150] The spring type is a return spring or an auxiliary spring, which can be installed at the front end or the rear end of the gas cylinder.

[0151] It should be noted that the cylinder with spring return function is provided with a special spring seat or spring bracket for fixing the spring and ensuring its correct position.

[0152] The embodiment of the present application also provides a photovoltaic system.
