Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a high-load photovoltaic support damper installation structure. Background Technology

[0002] With the rapid development of photovoltaic power generation technology, photovoltaic tracking brackets have been widely used in the industry due to their ability to effectively improve power generation efficiency. Especially in complex terrain conditions, such as mountains and slopes, the demand for tracking bracket installations is increasing. To enhance the wind resistance and operational stability of the bracket system under dynamic loads such as wind loads, dampers are usually installed at key parts of the bracket. The throttling effect of the internal damping medium improves the wind resistance of the bracket, thereby enhancing the overall structural stability.

[0003] Appendix Figure 1 This diagram illustrates a structural schematic of an existing damper protection state (damper mount without compensation, adverse wind load > offsettable wind load). The damper mount is a common structure without tilt compensation. S1 represents the adverse wind load, borne by the support itself, which has an adverse effect on the structure and undermines the overall stability of the support. S2 represents the external wind load, and S3 represents the offsettable wind load. Therefore, existing structures often lack reasonable installation design, and the damper's effectiveness is limited under large rotation angle operating conditions, preventing it from fully realizing its vibration reduction and stabilization functions in actual operation. Furthermore, most common damper installation structures currently only consider installation conditions on flat terrain, making it difficult to adapt to the adjustment needs of different slope terrains; those adapted to slope terrain are often at a fixed angle, making adjustment difficult.

[0004] Therefore, an installation structure is needed that can balance slope adaptability with maximizing damper effectiveness. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a damper installation structure for photovoltaic tracking brackets. This structure can adapt to terrain changes within a certain slope range while ensuring that the damper's vibration reduction and load-bearing performance is maximized under large-angle rotation conditions, thereby effectively improving the overall stability of the photovoltaic tracking bracket system under complex wind loads and during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-load photovoltaic bracket damper installation structure, comprising a damper, an inclined upper seat, an upper seat clamp, a T-shaped lower mounting seat, and a U-shaped adjustable lower seat; the inclined upper seat and the upper seat clamp are mounted opposite each other on both sides of the main shaft and are fixedly connected by a first fastener; the inclined upper seat includes a back plate and an inclined seat, the upper end of the inclined seat is fixedly connected to the back plate, and the lower end is hinged to the upper end of the damper through a first hinge; the T-shaped lower mounting seat is fixedly connected to the column through a second fastener; the U-shaped adjustable lower seat is connected to the T-shaped lower mounting seat through a third fastener and is hinged to the lower end of the damper through a second hinge to achieve adjustment of different installation angles.

[0007] Furthermore, the included angle between the back plate and the tilting seat is 60-75 degrees.

[0008] Furthermore, the tilting seat includes a first plate, a second plate, and a third plate connected in sequence in a U-shape; the first plate has a first through hole at the end away from the back plate for the first hinge to pass through, and the third plate has a second through hole at the end away from the back plate for the first hinge to pass through, with the first through hole and the second through hole being provided correspondingly.

[0009] Furthermore, a first clearance groove is formed in the middle of the lower end face of the first plate, and a second clearance groove is formed in the middle of the lower end face of the third plate, with the first clearance groove and the second clearance groove being provided correspondingly.

[0010] Furthermore, the U-shaped adjusting base includes a first hinge plate, a connecting plate, and a second hinge plate connected in sequence in a U-shape; the first hinge plate has a third through hole for the second hinge member to pass through, and the second hinge plate has a fourth through hole for the second hinge member to pass through, with the third and fourth through holes being correspondingly arranged.

[0011] Furthermore, the T-shaped mounting base includes a fixed base and a fixed plate, with the fixed base and the fixed plate being vertically connected; the fixed base has a fifth through hole for the third fastener to pass through, and the connecting plate has a sixth through hole for the third fastener to pass through.

[0012] Furthermore, the fixing plate has multiple seventh through holes for the second fastener to pass through.

[0013] The high-load photovoltaic support damper installation structure of this utility model adopts an installation method combining an inclined upper seat and a U-shaped adjustable lower seat. The U-shaped adjustable lower seat ensures installation adaptability within a certain slope angle range. At the same time, during the operation and protection of the photovoltaic support, the inclined upper seat allows the force generated by the wind load acting on the support system to be more effectively transmitted along the damper axis, reducing the adverse load on the support, thereby improving the damper's effectiveness in vibration reduction and structural stability, enhancing the support system's ability to resist wind-induced vibration and deformation, and improving its overall stability and wind resistance reliability.

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The overall structure of the photovoltaic support system is divided into a support node structure and a damper mounting structure 200. The support node structure serves as the carrier for the damper mounting structure 200 and is not the core component of this patent; it is only used to facilitate understanding of the damper installation. The support node structure includes a column 101, a welded bearing housing, a plastic bearing, a main shaft 102, and corresponding fasteners. The column 101 is made of H-beam (not limited to H-beam; it can be C-beam or a square tube, etc., with any cross-section pile foundation). The bearing housing is a welded bearing housing, installed on the column 101. A plastic bearing can be installed inside the bearing housing and rotate freely. The plastic bearing is cylindrical in shape and has double-sided flanges to restrict the degree of freedom of the plastic bearing and prevent it from slipping out of the bearing housing. The main shaft 102 has a square cross-section (not limited to a square; it can be any polygonal or irregularly shaped main shaft).

[0025] Please see the appendix Figure 2-8 This utility model provides a high-load photovoltaic support damper installation structure 200, including a damper 1, an inclined upper seat 2, an upper seat clamp 3, a T-shaped lower mounting seat 4, and a U-shaped adjustable lower seat 5. The damper 1, as the core vibration reduction element, effectively absorbs and dissipates wind load energy through the throttling effect of its internal damping medium, thereby enhancing the dynamic stability of the support system.

[0026] The tilting upper seat 2 and the upper seat clamp 3 are installed opposite each other on both sides of the main shaft 102 and are fixedly connected by the first fastener 6; the upper seat clamp 3 and the back plate 21 form a stable clamping structure to prevent the tilting upper seat 2 from shifting or loosening under dynamic load, and to ensure the reliability of the connection of the upper end of the damper 1.

[0027] As attached Figure 3 As shown, the tilting upper seat 2 includes a back plate 21 and an inclined tilting seat 22. The upper end of the tilting seat 22 is fixedly connected to the back plate 21, and the lower end is hinged to the upper end of the damper 1 through a first hinge 7. This ensures that during operation or protection, the angle between the direction of the wind load transmitted and the axis of the damper 1 is as small as possible, allowing external forces to be transmitted more effectively along the axis of the damper 1 rather than radially, reducing the radial component and thus better utilizing the damper 1's vibration reduction performance on the support, improving stability. Preferably, the tilting upper seat 2 is a welded part, and the upper seat clamp 3 is a bent sheet metal part. The first hinge 7 allows the upper end of the damper 1 to rotate freely on the tilting upper seat 2, adapting to angle changes during the rotation of the support.

[0028] The T-shaped mounting base 4 is fixedly connected to the column 101 by the second fastener 8. The T-shaped mounting base 4 is a T-shaped welded part, which serves as the mounting base of the lower end of the damper 1, providing a solid support point, dispersing the load transmitted by the damper 1, and enhancing the rigidity of the overall structure.

[0029] The U-shaped adjusting lower seat 5 is connected to the T-shaped mounting lower seat 4 via the third fastener 10, and is hinged to the lower end of the damper 1 via the second hinge 9 to achieve different installation angles to adapt to different slope angles. The U-shaped adjusting lower seat 5 is a U-shaped bent sheet metal part. The third fastener 10 locks the U-shaped adjusting lower seat 5 and the T-shaped mounting lower seat 4 to achieve reliable fixation of the slope angle.

[0030] The high-load photovoltaic bracket damper mounting structure 200 of this utility model has the following two states: The first is the running status (see appendix) Figure 7 The rotation of the main shaft 102 drives the tilting seat 2 to rotate, pulling the upper end of the damper 1 to achieve normal slow extension and retraction of the damper 1. The tilting seat 22 is tilted downwards, forming a certain angle with the horizontal direction, which is used to compensate for the fact that after the support rotates at a large angle, the angle between the axis of the damper 1 and the direction of the load force will not be too large.

[0031] The second is the protection state (see appendix) Figure 8 (Including the tilting upper seat 2 with tilt compensation): After the main shaft rotates to a specific angle, it stops rotating and enters a wind-resistant protection posture. The tilting upper seat 2 maintains a large angle with the upper end of the damper 1, so the force generated by the wind load acting on the support system can be more effectively transmitted along the axial direction of the damper 1, thereby improving the performance of the damper 1 in terms of support stability. As shown in the attached figure, S1 represents an adverse wind load, which is borne by the support itself and has an adverse effect on the structure, destroying the overall stability of the support; S2 represents an external wind load; S3 represents a wind load that can be offset and transmitted along the axial direction of the damper 1 to the damper 1, increasing the vibration reduction and wind resistance of the support and improving the overall stability performance.

[0032] Compared to the traditional horizontal installation method, the installation structure of the high-load photovoltaic support damper 1 of this utility model adopts an installation method combining an inclined upper seat 2 and a U-shaped adjustable lower seat 5. The U-shaped adjustable lower seat 5 ensures installation adaptability within a certain slope angle range. At the same time, during the operation and protection of the photovoltaic support, the inclined upper seat 2 allows the force generated by the wind load acting on the support system to be more effectively transmitted along the axial direction of the damper 1, reducing the adverse load on the support and thus improving the damper 1's efficiency in vibration reduction and structural stability. This enhances the support system's ability to resist wind-induced vibration and deformation, and improves its overall stability and wind resistance reliability.

[0033] Appendix Figure 8As shown, the angle between the back plate 21 and the tilting seat 22 is 60-75 degrees. When the support rotates at a large angle (such as in the protection state), it can effectively compensate for the angle between the axial direction of the damper 1 and the wind load direction, avoid the load transfer efficiency from being too large, and thus ensure that the damper 1 can still play its maximum role under extreme wind loads.

[0034] As attached Figure 3 As shown, the tilt seat 22 includes a first plate 221, a second plate 222, and a third plate 223 connected in a U-shape to form a stable three-sided support, enhancing the bending and torsional stiffness of the tilt seat 22. The first plate 221 has a first through hole at the end away from the back plate 21 for the first hinge 7 to pass through, and the third plate 223 has a second through hole at the end away from the back plate 21 for the first hinge 7 to pass through. The first through hole and the second through hole are correspondingly arranged to ensure that the hinge point between the upper end of the damper 1 and the tilt seat 22 is accurately aligned, reducing off-center load and wear, and improving connection life and reliability. Preferably, a first clearance groove 224 is formed in the middle of the lower end face of the first plate 221, and a second clearance groove 225 is formed in the middle of the lower end face of the third plate 223. The first clearance groove 224 and the second clearance groove 225 are correspondingly arranged to provide necessary movement space for the upper end of the damper 1, prevent interference when the bracket rotates or vibrates, ensure smooth movement of the hinge point, and avoid local stress concentration.

[0035] As attached Figure 4-6 As shown, the U-shaped adjusting lower seat 5 includes a first hinge plate 51, a connecting plate 52, and a second hinge plate 53 connected in sequence in a U-shape to form a rigid frame, effectively resisting the load torque transmitted by the damper 1; the first hinge plate 51 has a third through hole for the second hinge member 9 to pass through, and the second hinge plate 53 has a fourth through hole for the second hinge member 9 to pass through. The third and fourth through holes are arranged correspondingly so that the lower end of the damper 1 is aligned with the hinge point of the U-shaped adjusting lower seat 5, thereby improving the accuracy and stability of the angle adjustment.

[0036] The T-shaped mounting base 4 includes a fixed base 41 and a fixed plate 42. The fixed base 41 and the fixed plate 42 are vertically connected to form a T-shaped structure. The fixed plate 42 is connected to the column 101, and the fixed base 41 is connected to the U-shaped adjustable base 5 to distribute the load to the column 101 and enhance the overall installation rigidity. The fixed base 41 has a fifth through hole for the third fastener 10 to pass through, and the connecting plate 52 has a sixth through hole for the third fastener 10 to pass through, so as to realize the angle locking of the U-shaped adjustable base 5 and ensure that the installation is firm under different slope conditions.

[0037] The fixing plate 42 has multiple seventh through holes for the second fastener 8 to pass through, providing multiple installation points. This allows the second fastener 8 to select the optimal fixing position according to the actual structure of the column 101, enhancing installation flexibility and adaptability. It is suitable for columns 101 with different cross-sectional forms (such as H-beams, square tubes, etc.).

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
