Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a steel cable fixing device for a flexible photovoltaic support. Background Technology

[0002] Photovoltaic brackets play an important role in photovoltaic power generation systems as supporting structures for arranging and fixing photovoltaic panels. According to the different structural forms of the components connected to the photovoltaic panels, photovoltaic brackets can be divided into rigid photovoltaic brackets and flexible photovoltaic brackets. Among them, flexible photovoltaic brackets are often used in areas with relatively scarce land resources or poor terrain because of their advantages such as large span, high clearance, long row spacing and strong applicability.

[0003] In existing technologies, multi-row flexible photovoltaic (PV) supports typically consist of multiple support beams, with steel cables running between them, and PV panels are finally installed on the cables. Connecting blocks and U-shaped collars are installed at the top of the support beams, through which the steel cables are passed to connect to each support beam.

[0004] However, during actual installation, the steel cables are not securely fixed to the U-shaped collars, allowing them to slide within the collars. Since flexible photovoltaic (PV) systems are commonly used in mountainous environments with complex and varied terrain, they are typically installed following the contours of the land. Therefore, the steel cables usually have a slight bend when passing through the support beam. When the cables are tensioned or the PV panels are installed, this bend exerts a lateral force on the support beam. Because the connection between the cables and the U-shaped collars is not secure, the cables cannot restrain the beam's displacement, causing the support beam to pull on the support column, resulting in lateral bending or tilting. This severely affects the overall stability and safety of the PV system. Especially in mountainous environments, the complex terrain means the lateral forces on the support column can be even more varied and complex, further exacerbating the system's instability.

[0005] In addition, a loose connection between the steel cable and the U-shaped collar may cause the steel cable to break due to wear during long-term use. Especially under severe weather conditions such as strong winds and heavy rain, the instability of the support and the risk of steel cable breakage will be greatly increased. Utility Model Content

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section above, some embodiments of this application provide a steel cable fixing device for a flexible photovoltaic support, including a support beam, a connecting block fixed on the support beam, a first sliding groove fixed on the connecting block, a second sliding groove fixed on the first connecting block, first mounting holes symmetrically arranged on the connecting block, a U-shaped collar penetrating the first mounting hole, a first clamping mechanism penetrating the first sliding groove, a second clamping mechanism penetrating the second sliding groove, and a steel cable penetrating the U-shaped collar and penetrating both the first clamping mechanism and the second clamping mechanism.

[0008] Specifically, the U-shaped collar and the connecting block are fixed by a third nut.

[0009] Specifically, the first clamping mechanism includes a first pressure block, a first pad plate disposed on one side of the first slide groove, a second pad plate disposed on the other side of the first slide groove, a plurality of first bolts passing through the first pad plate and the second pad plate and passing through the first pressure block and the first slide groove, a plurality of first washers sleeved on the first bolts and in contact with the second pad plate, a first nut rotatably disposed on the first bolt, a first pressure groove fixedly disposed on the first pressure block, and a first positioning component slidably disposed on the first slide groove.

[0010] Specifically, the first positioning component includes a first slider that is slidably disposed on the first slide groove, a first positioning block that is fixedly disposed on the first slider, and a first positioning hole that is fixedly disposed on the second pad.

[0011] Specifically, the second clamping mechanism includes a second pressure block, a third pad disposed on one side of the second slide groove, a fourth pad disposed on the other side of the second slide groove, a plurality of second bolts passing through the third pad and the fourth pad and passing through the second pressure block and the second slide groove, a plurality of second washers sleeved on the second bolts and in contact with the fourth pad, a second nut rotatably disposed on the second bolt, a second pressure groove fixedly disposed on the second pressure block, and a second positioning component slidably disposed on the second slide groove.

[0012] Specifically, the second positioning component includes a second slider that is slidably disposed on the second slide groove, a second positioning block that is fixedly disposed on the second slider, and a second positioning hole that is fixedly disposed on the fourth gasket.

[0013] Specifically, the first and second slides are arc-shaped grooves.

[0014] Specifically, the center of the first and second slide grooves is the midpoint of the line connecting the centers of the two first mounting holes.

[0015] The beneficial effects of this utility model are:

[0016] (1) In the existing technology, the steel cable is not securely fixed to the U-shaped collar, allowing it to slide within the collar. When the steel cable is bent at the connection point with the support beam, it exerts a lateral force on the support beam, causing the support beam to bend or tilt. This severely affects the overall stability and safety of the photovoltaic support system. The first and second clamping mechanisms can fix the steel cable to the connecting block. Even if the steel cable exerts a lateral force on the support beam, the support system will not tilt due to the secure connection between the steel cable and the support beam, provided the cable is pulled and restrained.

[0017] (2) The first bolt needs to pass through the first pressure block, the first pad, the first slide groove and the second pad. Therefore, during the installation process, the hole position will be repeatedly aligned, which will affect the installation efficiency. By setting the first positioning block and the first positioning hole, the first positioning hole on the second pad is aligned with the first positioning block during installation, which can achieve pre-alignment, facilitate the insertion of the first bolt and improve the installation efficiency.

[0018] (3) The second bolt needs to pass through the second pressure block, the third pad, the second slide groove and the fourth pad. Therefore, during the installation process, the hole position will be repeatedly aligned, which will affect the installation efficiency. By setting the second positioning block and the second positioning hole, the second positioning hole on the fourth pad is aligned with the second positioning block during installation, which can achieve pre-alignment, facilitate the insertion of the second bolt and improve the installation efficiency.

[0019] (4) Since the installation sites of flexible photovoltaic brackets are usually in poor terrain, the brackets need to be installed according to the slope, which leads to large variations in the height of each bracket. The steel cables also need to be installed to accommodate the height differences of the brackets, and they will have a certain angle when passing over the bracket beam. The arc-shaped groove design on the connecting block makes this utility model more applicable, allowing for the installation of steel cables with different angles. This not only improves installation efficiency but also ensures a firm connection between the steel cables and the bracket beam, avoiding safety hazards caused by improper angles. In other words, this utility model can meet the steel cable installation needs of photovoltaic brackets in different terrains. Attached Figure Description

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1-5As shown, the steel cable fixing device for a flexible photovoltaic support according to this utility model includes a support beam 1, a connecting block 2 fixed on the support beam, a first sliding groove 3 fixed on the connecting block, a second sliding groove 4 fixed on the first connecting block, first mounting holes 5 symmetrically arranged on the connecting block, a U-shaped collar 6 penetrating the first mounting hole, a first clamping mechanism 7 penetrating the first sliding groove, a second clamping mechanism 8 penetrating the second sliding groove, and a steel cable 9 penetrating the U-shaped collar and penetrating both the first clamping mechanism and the second clamping mechanism. The support beam is used to connect each flexible photovoltaic support and is horizontally arranged on each flexible photovoltaic support. The structure consists of an L-shaped connecting block, a first and a second sliding groove, and a U-shaped collar with threads at both ends. The U-shaped collar is inserted into the first mounting hole, forming a hole with the connecting block. The steel cable passes through this hole, and the contact point between the cable and the U-shaped collar is located on the central axis. A first and a second clamping mechanism clamp and fix the cable. In existing technology, the cable is not securely fixed to the U-shaped collar, allowing it to slide within the collar. When the cable bends at its connection to the support beam, it exerts a lateral force on the beam, causing the support beam to bend or tilt. This severely affects the overall stability and safety of the photovoltaic support system. The first and second clamping mechanisms can fix the cable to the connecting block. Even if the cable exerts a lateral force on the beam, the support system remains stable due to the secure connection between the cable and the beam, preventing tilting caused by the cable's traction and restraint.

[0034] Specifically, the U-shaped collar and the connecting block are fixed by a third nut 61; by tightening the third nut, the inner wall of the U-shaped collar contacts the steel cable, and cooperates with the connecting block to initially fix the steel cable. Then, the steel cable is tensioned, and after tensioning is complete, the first clamping mechanism and the second clamping mechanism can be installed.

[0035] Specifically, the first clamping mechanism includes a first pressure block 71, a first pad 72 disposed on one side of the first slide groove, a second pad 73 disposed on the other side of the first slide groove, a plurality of first bolts 74 passing through the first pad and the second pad and passing through the first pressure block and the first slide groove, a plurality of first washers 75 sleeved on the first bolts and in contact with the second pad, a first nut 76 rotatably disposed on the first bolt, a first pressure groove 77 fixedly disposed on the first pressure block, and a first positioning component 78 slidably disposed on the first slide groove; the steel cable passes through the first pressure groove; after installation, by tightening the first nut, the first pad and the second pad are clamped on both sides of the connecting block, and the first pressure block is close to the first pad, the first pressure groove is in contact with the steel cable, and the first pressure block and the first pad together clamp and fix the steel cable.

[0036] Specifically, the first positioning component includes a first slider 782 slidably disposed on a first slide groove, a first positioning block 783 fixedly disposed on the first slider, and a first positioning hole 784 fixedly disposed on a second pad. The first slider is an arc-shaped slider slidably disposed on the first slide groove. The first positioning block is rectangular with unequal length and width. The first positioning hole is a rectangular hole with the same shape as the first positioning block. The first bolt needs to pass through the first pressure block, the first pad, the first slide groove, and the second pad. Therefore, during installation, there will be repeated alignment of the hole positions, which affects the installation efficiency. By setting the first positioning block and the first positioning hole, the first positioning hole on the second pad is aligned with the first positioning block during installation, achieving pre-alignment, which facilitates the insertion of the first bolt and improves the installation efficiency.

[0037] Specifically, the second clamping mechanism includes a second pressure block 81, a third pad 82 disposed on one side of the second slide groove, a fourth pad 83 disposed on the other side of the second slide groove, a plurality of second bolts 84 passing through the third pad and the fourth pad and passing through the second pressure block and the second slide groove, a plurality of second washers 85 sleeved on the second bolts and in contact with the fourth pad, a second nut 86 rotatably disposed on the second bolt, a second pressure groove 87 fixedly disposed on the second pressure block, and a second positioning component 88 slidably disposed on the second slide groove; the steel cable passes through the first pressure groove and the U-shaped collar and then exits through the second pressure groove; after installation, by tightening the second nut, the third pad and the fourth pad are clamped on both sides of the connecting block, and the second pressure block is close to the third pad, the second pressure groove is in contact with the steel cable, and the second pressure block and the third pad together clamp the steel cable.

[0038] Specifically, the second positioning component includes a second slider 882 slidably disposed on the second slide groove, a second positioning block 883 fixedly disposed on the second slider, and a second positioning hole 884 fixedly disposed on the fourth pad. The second slider is an arc-shaped slider slidably disposed on the second slide groove. The second positioning block is rectangular with unequal length and width. The second positioning hole is a rectangular hole with the same shape as the second positioning block. The second bolt needs to pass through the second pressure block, the third pad, the second slide groove, and the fourth pad. Therefore, during installation, there will be repeated alignment of the hole positions, which affects the installation efficiency. By setting the second positioning block and the second positioning hole, the second positioning hole on the fourth pad is aligned with the second positioning block during installation, achieving pre-alignment, which facilitates the insertion of the second bolt and improves the installation efficiency.

[0039] Specifically, the first and second chutes are arc-shaped grooves. Since the installation sites of flexible photovoltaic supports are usually in poor terrain, the supports need to be installed following the slope, which leads to significant height variations among the supports. Therefore, the steel cables also need to be installed to accommodate these height differences. When the steel cables pass over the support beam, they will have a certain angle. The arc-shaped chutes on the connecting block make this invention more versatile, allowing for the installation of steel cables with different angles. This not only improves installation efficiency but also ensures a secure connection between the steel cables and the support beam, avoiding safety hazards caused by improper angles. In other words, this invention can meet the steel cable installation needs of photovoltaic supports in different terrains.

[0040] Specifically, the center of the first and second sluices is the midpoint of the line connecting the centers of the two first mounting holes. Since the installation sites of flexible photovoltaic brackets are usually in poor terrain, the brackets need to be installed according to the slope, which will result in a large variation in the height of each bracket. Therefore, the steel cable also needs to be installed in accordance with the height difference of the adjacent brackets. When the steel cable is under tension during installation, it will drive the first and second sliders to slide in the first and second sluices respectively, thereby adjusting the installation angles of the first pressure block, the first pad, the second pad, the second pressure block, the third pad, and the fourth pad. Ultimately, the first pressure block, the first pad, the second pad, the second pressure block, the third pad, and the fourth pad can be installed in accordance with the height difference of the steel cable and the adjacent brackets. At the same time, when the steel cable pulls the bracket, since the center of the first and second sluices is the midpoint of the line connecting the centers of the two first mounting holes, that is, the line connecting the collar and the first pressure block is collinear with the line connecting the first pressure block to the second pressure block on the adjacent bracket, the force is more direct and will not generate component forces in other directions.
