[0059] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0060] This application discloses a photovoltaic bracket 10.

[0061] The following is for reference. Figures 1-9A photovoltaic bracket 10 according to an embodiment of this application is described.

[0062] In some embodiments, such as Figures 1-3 As shown, the photovoltaic support 10 includes: a column 11, a main shaft 12, a push rod 13, a base 141, an adjusting gear 15, and a rack 16.

[0063] like Figure 5 and Figure 6 As shown, the main shaft 12 is pivotally supported on the column 11; the two ends of the push rod 13 are hinged to the column 11 and the main shaft 12 respectively, and the push rod 13 is pivotally mounted with a power input shaft 131 for driving the extension and retraction of the push rod 13; the base 141 is mounted on the push rod 13; the adjusting gear 15 is pivotally mounted on the base 141, and the adjusting gear 15 is coupled to the power input shaft 131; the rack 16 is slidably mounted on the base 141, and the rack 16 meshes with the adjusting gear 15.

[0064] The column 11 serves as the supporting foundation for the entire photovoltaic bracket 10 and can be made of materials such as metal pipes or precast concrete components. The shape of the column 11 can be circular, square, or other polygonal, etc., and this application embodiment does not limit this.

[0065] The main shaft 12 can be mounted on the column 11 by means of rotating support components such as bearings. The photovoltaic module 20 can be mounted on the main shaft 12 by means of a triangular support. The cross-sectional shape of the main shaft 12 can be circular or square, etc., and this application embodiment does not limit it.

[0066] The push rod 13 is configured to be telescopic. Specifically, the push rod 13 may include a main rod body and a telescopic rod. The main rod body may be hinged to the column 11, and the telescopic rod may be hinged to the main shaft 12. The power input shaft 131 and the telescopic rod may be connected by a lead screw mechanism or other transmission mechanism. When the power input shaft 131 is driven to rotate, the telescopic rod may extend or retract relative to the main rod body to drive the main shaft 12 to rotate, thereby adjusting the tilt angle of the photovoltaic module 20.

[0067] The base 141 can be mounted on the push rod 13 by welding, bolting, or snap-fitting to support the adjusting gear 15 and the rack 16. The shape and size of the base 141 can be designed according to the installation requirements of the adjusting gear 15 and the rack 16, and this embodiment does not limit this.

[0068] The rack 16 drives the power input shaft 131 to rotate through the adjusting gear 15. The connection between the adjusting gear 15 and the power input shaft 131 can be, but is not limited to, plug-in connection, key connection or meshing connection of the adjusting gear 15, etc. The embodiments of this application do not limit this.

[0069] For example, in some embodiments, such as Figure 6As shown, the power input shaft 131 can be directly inserted into the adjusting gear 15 so that the adjusting gear 15 and the power input shaft 131 can rotate coaxially.

[0070] In actual implementation, such as Figures 1-3 , Figure 5 and Figure 6 As shown, the operator can manually pull the rack 16. Since the rack 16 meshes with the adjusting gear 15, the linear motion of the rack 16 can drive the adjusting gear 15 to rotate around its pivot center. The adjusting gear 15 transmits the rotational motion to the power input shaft 131, driving the power input shaft 131 to rotate. The power input shaft 131 converts the rotational motion into linear motion through a lead screw mechanism or other transmission mechanism, thereby driving the push rod 13 to extend or retract. The extension or retraction of the push rod 13 drives the main shaft 12 to rotate on the column 11, thereby changing the angle of the photovoltaic bracket 10. During this process, the operator can adjust the angle of the photovoltaic bracket 10 by continuously pulling the rack 16 according to the optimal light-receiving angle of the photovoltaic module 20 until a satisfactory position is achieved.

[0071] The photovoltaic bracket 10 provided in this application embodiment, through the power coupling design of the adjusting gear 15, rack 16 and push rod 13, reduces procurement and maintenance costs compared to traditional hydraulic adjustment devices and electric push rod 13 type adjustment devices. At the same time, it simplifies the installation process, eliminating the need for complex hydraulic pipelines or electrical wiring, thus reducing installation costs. The manual operation of pulling the rack 16 is not only simple and easy to understand, but also allows for flexible adjustment of the angle of the photovoltaic module 20 according to the actual site conditions. Due to the reduced cost and simplified operation, the photovoltaic bracket 10 can be applied to various site conditions without being limited by electric or hydraulic power supply, thereby greatly improving the applicability and flexibility of the photovoltaic bracket 10, which is conducive to large-scale promotion and popularization. In addition, the overall structure is simple, reducing the number of parts and possible failure points, and is not affected by problems such as hydraulic oil leakage or motor failure, thereby enhancing the adaptability of the photovoltaic bracket 10 in harsh environments and improving the operational reliability of the photovoltaic bracket 10.

[0072] In some embodiments, such as Figure 1 and Figure 4 As shown, multiple columns 11 are provided, and the multiple columns 11 are distributed at intervals. A push rod 13 is provided between the main shaft 12 and each column 11. The photovoltaic bracket 10 also includes a drive shaft 18.

[0073] like Figure 4 and Figure 6 As shown, a drive shaft 18 is provided between two adjacent push rods 13. The drive shaft 18 is coupled to the power input shaft 131. The base 141, the adjusting gear 15 and the rack 16 are installed on at least one push rod 13 at the outermost end.

[0074] In this context, "multiple" means two or more. For example, in some embodiments, 15 columns 11 are provided, which are distributed at intervals. A push rod 13 is provided between the main shaft 12 and each column 11.

[0075] The base 141, adjusting gear 15 and rack 16 can be mounted on at least one of the two outermost push rods 13 of a plurality of spaced push rods 13.

[0076] For example, in some embodiments, such as Figure 4 and Figure 6 As shown, the base 141, adjusting gear 15, and rack 16 can be mounted on one of the two outermost push rods 13 among a plurality of spaced-apart push rods 13. For the push rod 13 with the base 141, adjusting gear 15, and rack 16 mounted, one end of the power input shaft 131 of the push rod 13 is connected to the adjusting gear 15, and the other end of the power input shaft 131 is connected to the drive shaft 18; for the other push rods 13, both ends are connected to two drive shafts 18 respectively.

[0077] For example, in some other embodiments, the two outermost push rods 13 of the spaced-apart push rods 13 are each equipped with a base 141, an adjusting gear 15, and a rack 16.

[0078] The connection method between the push rod 13 and the drive shaft 18 may include, but is not limited to, bolt connection, pin connection or snap connection, etc., and the embodiments of this application do not limit this.

[0079] In actual implementation, such as Figure 1 , Figure 4 and Figure 6 As shown, the operator can manually pull the rack 16 on one of the outermost push rods 13. Since the rack 16 meshes with the adjusting gear 15, the linear motion of the rack 16 can drive the adjusting gear 15 to rotate around its pivot center. The adjusting gear 15 transmits the rotational motion to the directly connected power input shaft 131 to drive the power input shaft 131 to rotate. The power input shaft 131 can not only drive the push rod 13 it is located to extend and retract, but also transmit the motion to the adjacent push rods 13 through the transmission shaft 18. Each push rod 13 extends and retracts synchronously under the drive of the transmission shaft 18, so as to realize the multi-point drive of multiple push rods 13 along the length direction of the main shaft 12, thereby driving the main shaft 12 to rotate relative to the column 11 at multiple points, and thus realizing the angle adjustment of the entire photovoltaic bracket 10.

[0080] The photovoltaic bracket 10 provided in this application embodiment, through the aforementioned transmission shaft 18, transmits power from one push rod 13 to other push rods 13, realizing the synchronous extension and retraction of multiple push rods 13. This reduces the risk of the main shaft 12 twisting or the photovoltaic module 20 being subjected to uneven force due to asynchrony, thereby improving the adjustment accuracy. The multi-column design 11 can support a longer main shaft 12 and is easy to expand according to the size and number of photovoltaic modules 20. Only the number of columns 11, push rods 13 and transmission shaft 18 needs to be increased, which increases the diversity and scalability of the photovoltaic bracket 10. Moreover, only the outermost push rod 13 needs to be adjusted to control the entire row of brackets, which greatly reduces the adjustment time and manpower input. It is especially suitable for large-scale photovoltaic arrays, thereby further increasing the usable width of the photovoltaic bracket 10 without affecting the adjustment efficiency.

[0081] In some embodiments, such as Figure 4 As shown, the drive shaft 18 includes a main body section 181 and an adjusting section 182, and at least a portion of the adjusting section 182 overlaps with the main body section 181.

[0082] The adjusting section 182 and the main body section 181 are detachably connected at the overlapping position. Specifically, the overlapping area between the main body section 181 and the adjusting section 182 can be connected by bolts, pins or clamps, etc. This application embodiment does not limit this.

[0083] Understandably, during the installation of the photovoltaic bracket 10, if the operator finds that the distance between two adjacent push rods 13 deviates from the expected distance due to processing or assembly reasons, the drive shaft 18 can be adjusted by changing the overlap length of the main body section 181 and the adjusting section 182. Specifically, depending on the magnitude of the deviation, a suitable connection method is selected to adjust the main body section 181 and the adjusting section 182. If a bolt connection is used, loosen the bolts, increase or decrease the overlap length between the adjusting section 182 and the main body section 181 according to actual needs, and then retighten the bolts. If a pin connection is used, pull out the pin, adjust the overlap length according to actual needs, and then insert the pin. If a clamp connection is used, loosen the clamp bolts, adjust the position, and then retighten them. If, during the subsequent use of the photovoltaic bracket 10, slight deformation of the structure occurs due to environmental factors or other reasons, affecting the coordinated work of multiple push rods 13, the adjustment section 182 of the corresponding transmission shaft 18 can be adjusted again according to the above steps, so that the transmission shaft 18 can smoothly transmit the rotation of the power input shaft 131 to each push rod 13, enabling multiple push rods 13 to extend and retract synchronously, thereby achieving the correct adjustment of the angle of the photovoltaic bracket 10.

[0084] The photovoltaic bracket 10 provided in this application embodiment, by configuring the drive shaft 18 as a structure composed of a detachable overlapping main body section 181 and an adjusting section 182, can effectively compensate for distance errors caused by insufficient processing precision or improper assembly during installation, thereby improving the installation success rate and overall performance of the photovoltaic bracket 10. On the other hand, the detachable connection method allows for convenient replacement of either the main body section 181 or the adjusting section 182 when the drive shaft 18 fails, without the need to replace the entire drive shaft 18, thereby reducing maintenance costs and time, and improving the maintainability of the photovoltaic bracket 10. Furthermore, by setting the adjusting section 182, the requirements for processing and assembly precision are reduced to a certain extent, allowing for the use of relatively low-cost processing techniques and assembly methods, while reducing scrap and rework rates caused by processing and assembly errors, thereby optimizing the overall manufacturing cost of the photovoltaic bracket 10.

[0085] In some embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the photovoltaic bracket 10 also includes: a stop 142 and a limit card 143.

[0086] like Figure 5 and Figure 7 As shown, the stop 142 is pivotally mounted on the base 141; the limit clip 143 can selectively connect the stop 142 and the base 141 to clamp the rack 16 between the adjusting gear 15 and the stop 142.

[0087] In this embodiment, such as Figure 5 and Figure 7 As shown, one end of the stop 142 can be rotatably mounted on the base 141 between a first position and a second position via a detachable pivot. When the photovoltaic bracket 10 is assembled and the adjustment function is normal, the stop 142 is in the first position. The limit card 143 connects the side of the stop 142 away from its own pivot to the base 141, restricting the rotation of the stop 142. At this time, the stop 142 blocks the opening at the top of the base 141, and the rack 16 installed in the base 141 is stably and reliably clamped between the adjusting gear 15 and the stop 142. When the operator needs to maintain the photovoltaic bracket 10, the operator can remove the limit card 143 from the stop 142 and the base 141, and rotate the stop 142 from the first position to the second position, so that the top of the base 141 is completely open, and the rack 16 installed in the base 141 can be disengaged from this opening for maintenance or replacement.

[0088] The photovoltaic bracket 10 provided in this application embodiment, through the setting of the stop 142 and the limiting card 143, firmly clamps the rack 16 between the adjusting gear 15 and the stop 142, reducing the risk of the rack 16 falling off the base 141 during the adjustment process, so that the rack 16 always maintains the correct coupling connection with the adjusting gear 15 during the adjustment, thereby increasing the stability and reliability of the adjustment process, and improving the adjustment efficiency. In addition, the detachable design of the limiting card 143 greatly increases the limiting of the rack 16 and the convenience of the removal process, thereby significantly improving the installation efficiency and maintainability of the photovoltaic bracket 10.

[0089] In some embodiments, such as Figure 8 As shown, the limiting card 143 pivotally passes through the stop 142 and the base 141, and includes a main body 1431, a screwing part 1433 and a protrusion 1432. The screwing part 1433 is connected to the end face of the main body 1431, and the protrusion 1432 is connected to the side of the main body 1431. The stop 142 has a first hole 1421 for inserting the main body 1431, and the base 141 has a second hole 14121 for inserting the main body 1431 and a third hole 14122 for avoiding the protrusion 1432. The second hole 14121 and the third hole 14122 are connected. When the protrusion 1432 is located between the side of the stop 142 away from its own axis of rotation and the base 141, the end of the main body 1431 away from the screwing part 1433 is located in the first hole 1421.

[0090] The first hole 1421 and the second hole 14121 can be circular so that the limiting card 143 can rotate flexibly when inserted into the first hole 1421 and the second hole 14121.

[0091] like Figure 8 As shown, the limiting card 143 can be designed as a key-shaped structure. Specifically, the main body 1431 can be designed as a straight rod structure for passing through the first hole 1421 and the second hole 14121. The screwing part 1433 is a sheet-like structure connected to the end face of the straight rod structure for operation. The protrusion 1432 is an enlarged structure connected to the side wall of the straight rod structure.

[0092] The shape of the third hole 14122 matches the shape of the protrusion 1432. The shape of the protrusion 1432 may include, but is not limited to, cylindrical, prismatic, conical or other irregular shapes. This application embodiment does not limit this.

[0093] In actual implementation, such as Figure 8As shown, during the assembly process of the limit card 143, the operator pinches the screwing part 1433, aligns the main body 1431 with the second hole 14121 of the base 141 and the first hole 1421 of the stop member 142 along the insertion direction, and aligns the protrusion 1432 with the third hole 14122 of the base 141 along the insertion direction. The end of the main body 1431 of the limit card 143 first passes through the second hole 14121 of the base 141. Under the continuous pushing of the operator, the main body 1431 slides a certain distance along the second hole 14121, and then the protrusion 1432 passes through the third hole 14122 of the base 141 ... main body 1431 slides a certain distance along the second hole 14121, and then the protrusion 1432 passes through the third hole 14122 of the base 141. The second hole 14121 continues to slide until it is inserted into the first hole 1421 of the stop 142. At this time, the protrusion 1432 is located between the side of the stop 142 away from its own axis of rotation and the base 141. Then, the operator can rotate the screwing part 1433, thereby driving the main body 1431 connected to the screwing part 1433 to rotate synchronously, thereby driving the protrusion 1432 to rotate, so that the protrusion 1432 and the third hole 14122 are misaligned in the insertion direction. In this way, when the limit card 143 receives external disturbance and has a tendency to move outward, the protrusion 1432 can abut against the inner wall of the base 141 to prevent the limit card 143 from sliding.

[0094] The photovoltaic bracket 10 provided in this application embodiment, through the above-mentioned main body 1431, protrusion 1432, screwing part 1433, first hole 1421, second hole 14121 and third hole 14122, combined with the rotatable design of the limiting card 143, the protrusion 1432 can be smoothly assembled between the side of the stop 142 away from its own rotation axis and the base 141 through the third hole 14122. The operator can rotate the limiting card 143 to offset the protrusion 1432 from the third hole 14122, thereby realizing the rotational limitation of the limiting card 143 by utilizing the positional change of the protrusion 1432 after rotation, reducing the risk of the limiting card 143 falling off the base 141 and the stop 142, further enhancing the reliability of the rack 16 clamped between the adjusting gear 15 and the stop 142, minimizing the risk of the rack 16 falling off the base 141 during the adjustment process, and further increasing the stability and reliability of the adjustment process.

[0095] In some embodiments, such as Figure 9 As shown, the adjusting gear 15 includes a gear body 151 and a sleeve 152.

[0096] The gear body 151 is used to mesh with the rack 16; the sleeve 152 passes through the base 141 and the gear body 151, the sleeve 152 has a mounting groove for inserting the power input shaft 131, and the end of the sleeve 152 opposite to the power input shaft 131 has a limiting boss 1521, which is located outside the base 141.

[0097] The gear body 151 is used to realize the power transmission between the rack 16 and the power input shaft 131. The number of teeth and the module of the gear body 151 should be designed according to the size of the rack 16 and the expected adjustment accuracy. This application embodiment does not limit this.

[0098] The sleeve 152 is used to form a mounting groove suitable for mounting the power input shaft 131 and to realize the assembly of the adjusting gear 15 on the base 141. The shape of the mounting groove may include, but is not limited to, square, polygonal, waist-shaped or other non-circular shapes, in order to reduce the relative rotation between the power input shaft 131 and the gear body 151, and to make the gear body 151 and the power output shaft rotate synchronously along the same axis as much as possible.

[0099] Understandably, since the sleeve 152 penetrates both the base 141 and the gear body 151, in other words, the gear body 151 is indirectly mounted within the base 141 via the sleeve 152. This restricts the radial displacement of the gear body 151, thereby reducing the probability of the gear body 151 detaching from the base 141. Furthermore, since the end of the sleeve 152 facing away from the power input shaft 131 has a limiting boss 1521, and the limiting boss 1521 is located outside the base 141, even if the sleeve 152 is subjected to external disturbances and tends to move inward, the limiting boss 1521 can abut against the outer wall of the base 141 to prevent excessive slippage of the sleeve 152, thereby minimizing the probability of the gear body 151 detaching from the base 141.

[0100] In some embodiments, such as Figures 7-9 As shown, the base 141 includes: a clamping plate 1411 and a support base 1412.

[0101] like Figure 7 and Figure 9 As shown, the clamping plate 1411 clamps the push rod 13, and the clamping plate 1411 is provided with a positioning structure 14111 for abutting the push rod 13; the support base 1412 clamps the clamping plate 1411, the rack 16 and the gear body 151 are located between the support base 1412 and the clamping plate 1411, and the sleeve 152 passes through the support base 1412 and the clamping plate 1411.

[0102] The positioning structure 14111 can be designed as, but is not limited to, a positioning plate, a positioning block, or a positioning post, etc., and the embodiments of this application do not limit it.

[0103] In this embodiment, such as Figures 7-9As shown, the clamping plate 1411 can be designed as a U-shaped structure. The opening of the clamping plate 1411 is aligned with the side of the push rod 13 and slowly inserted until the push rod 13 stops against the positioning structure 14111 on one side wall of the adjusting gear 15, indicating that the clamping plate 1411 is assembled in place. The clamping plate 1411 applies compressive stress to at least two side walls of the push rod 13. At the same time, the clamping plate 1411 can also be further reinforced with the push rod 13 by welding or bolt connection. The support base 1412 can be designed as a U-shaped structure with a larger size than the clamping plate 1411. In actual operation, the adjusting gear 15, rack 16, limit card 143 and stop 142 can be assembled on the support base 1412 first. Then, the opening of the support base 1412 is aligned with the side wall of the clamping plate 1411 and the mounting groove of the sleeve 152 is aligned with the power input shaft 131 and slowly inserted. After assembly, the stop 142 should be spaced apart from the clamping plate 1411 to prevent the clamping plate 1411 from interfering with the rotation of the stop 142. At the same time, the support base 1412 can also be further reinforced with the clamping plate 1411 by welding or bolt connection.

[0104] The photovoltaic bracket 10 provided in this application embodiment, by designing the base 141 as a structure composed of a clamping plate 1411 and a support base 1412, achieves precise assembly of the adjusting gear 15, rack 16, stop 142, and limit card 143. At the same time, by utilizing the clamping design of the clamping plate 1411 to hold the push rod 13, the base 141 is quickly inserted and assembled on the push rod 13, improving the assembly efficiency of the entire photovoltaic bracket 10. Combined with the positioning structure 14111 on the clamping plate 1411, the relative position of the push rod 13 and the base 141 can be accurately fixed, reducing the problem of poor power transmission or wear of the adjusting gear 15 caused by installation errors, thereby significantly improving the installation accuracy of components such as the base 141, adjusting gear 15, and rack 16.

[0105] In some embodiments, such as Figure 1 and Figures 5-7 As shown, the photovoltaic bracket 10 also includes a handle 17.

[0106] like Figures 5-7 As shown, the handle 17 is mounted on the end of the rack 16 for operation.

[0107] The handle 17 can be designed in a shape that is easy to grip, such as round, oval, curved or flat, and the surface of the handle 17 can have a non-slip texture or coating to increase friction.

[0108] The connection method between the handle 17 and the end of the rack 16 may include, but is not limited to, bolt connection, snap-fit, riveting, welding or integral molding, etc., and the embodiments of this application do not limit this.

[0109] Understandably, the introduction of the handle 17 makes the operation of the photovoltaic bracket 10 more user-friendly. Operators can more easily pull and pull the rack 16. Compared to directly gripping the rack 16 with their hands, the handle 17 provides a more comfortable and stable grip, reducing the slippage and discomfort that may occur when the hand is in direct contact with the rack 16. Operators can more easily control the movement of the rack 16, thereby improving the efficiency of angle adjustment of the photovoltaic bracket 10. Furthermore, the well-designed shape of the handle 17 allows operators to more easily grip it and apply force to pull the rack 16, achieving a larger displacement with less force. This effectively reduces the operator's workload and lowers the difficulty of operation, especially when a larger adjustment force is required.

[0110] In some embodiments, such as Figures 1-3 As shown, the photovoltaic bracket 10 also includes a first support 191 and a second support 192.

[0111] like Figure 5 and Figure 6 As shown, the first support 191 includes a clamp 1911 and a connecting rod 1912 connected to the clamp 1911. The clamp 1911 is sleeved on the outside of the main shaft 12, and the end of the connecting rod 1912 away from the clamp 1911 is hinged to the top of the push rod 13. The second support 192 includes an assembly plate 1921 and a hinge support 1922. The assembly plate 1921 is connected to the side wall of the column 11, and the hinge support 1922 is installed on the side of the assembly plate 1921 away from the column 11, and the hinge support 1922 is hinged to the bottom end of the push rod 13.

[0112] The clamp 1911 is fixedly connected to the spindle 12 to provide stable support. The clamp 1911 can be designed as an adjustable ring structure, such as a two-half structure or an integrated elastic clamp, and is fitted onto the outside of the spindle 12 by bolts or clips.

[0113] The connecting rod 1912 is connected between the clamp 1911 and the push rod 13 to transmit power and maintain structural stability. The connecting rod 1912 can be movably hinged to the top of the push rod 13 via a hinge shaft. In other words, the rotation axis of the top of the push rod 13 is movable in space, thereby providing sufficient freedom for the extension and retraction of the push rod 13.

[0114] The connection method between the connecting rod 1912 and the clamp 1911 may include, but is not limited to, welding, bolting or riveting, etc., and this application embodiment does not limit this.

[0115] The assembly plate 1921 is fixedly connected to the side wall of the column 11, providing an installation base for the hinge support 1922 and the push rod 13. The assembly plate 1921 can be designed as a flat plate structure. The assembly plate 1921 can be fixed to the column 11 by means of bolt connection, riveting or welding. The bottom of the hinge support 1922 can be fixed to the assembly plate 1921 by means of welding, bolt connection or riveting. This application embodiment does not limit this.

[0116] The hinge support 1922 can be fixedly hinged to the bottom end of the push rod 13 via the hinge shaft. In other words, the rotation axis of the bottom end of the push rod 13 is not movable in space, which restricts the translational degree of freedom of the bottom end of the push rod 13, but allows the bottom end of the push rod 13 to rotate within a certain range.

[0117] The photovoltaic bracket 10 provided in this application embodiment, through the aforementioned first support 191 and second support 192, provides structural support for the power transmission between the telescopic push rod 13, the adjusting gear 15, and the main shaft 12. The first support 191 holds the main shaft 12 tightly through the clamp 1911, and the connecting rod 1912 is hinged to the top of the push rod 13. The second support 192 is connected to the column 11 through the mounting plate 1921, and the hinge support 1922 is hinged to the bottom of the push rod 13. This connection method provides a stable support point for the push rod 13, allowing the push rod 13 to extend and retract freely during adjustment, while maintaining stability during extension and retraction. This contributes to the structural stability of the entire photovoltaic bracket 10, effectively resisting external forces such as wind, thereby increasing the reliability and stability of the photovoltaic bracket 10 during operation.

[0118] This application also discloses a photovoltaic power generation system.

[0119] In some embodiments, such as Figure 1 As shown, the photovoltaic power generation system includes: photovoltaic modules 20 and photovoltaic brackets 10 as described in any of the above embodiments.

[0120] like Figure 2 and Figure 3 As shown, the photovoltaic module 20 is mounted on the main shaft 12 of the photovoltaic bracket 10.

[0121] The photovoltaic power generation system provided in this application embodiment, through the setting of the photovoltaic bracket 10, reduces procurement and maintenance costs compared to traditional hydraulic adjustment devices and electric push rod type 13 adjustment devices. At the same time, it simplifies the installation process, eliminating the need for complex hydraulic pipelines or electrical wiring installation, thus reducing installation costs. The manual operation of pulling the rack 16 is not only simple and easy to understand, but also allows for flexible adjustment of the angle of the photovoltaic module 20 according to the actual site conditions. Due to the reduced cost and simplified operation, the photovoltaic bracket 10 can be applied to various site conditions without being limited by electric or hydraulic power supply, thereby greatly improving the applicability and flexibility of the photovoltaic bracket 10, which is conducive to large-scale promotion and popularization. In addition, the overall structure is simple, reducing the number of parts and possible failure points, and is not affected by problems such as hydraulic oil leakage or motor failure, thereby enhancing the adaptability of the photovoltaic bracket 10 in harsh environments and improving the operational reliability of the photovoltaic bracket 10.
