Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, and in particular to a flexible photovoltaic support system for mountainous areas. Background Technology

[0002] In mountain photovoltaic projects, steep slopes, undulating terrain, and various irregular changes are often encountered. Under these complex mountain conditions, the drawbacks of traditional fixed photovoltaic support structures are becoming increasingly apparent. Due to the complexity of the terrain, traditional fixed photovoltaic support structures cannot be used for installation in many cases, reducing land use efficiency and affecting the overall photovoltaic power generation capacity.

[0003] Existing technology, CN2024118381641, describes a three-cable photovoltaic flexible support system. Currently, the column design of flexible supports, when used on sites with steep slopes, often results in an angled contact point between the steel cable and the anchor when the cable is installed on the end column via anchors. This can lead to fatigue failure at the contact point during long-term swaying, posing a safety hazard to the support. Simultaneously, at the middle column, the contact point between the fixed rope clamp and the steel cable also has a large angle, which can easily cause wear and damage to the steel cable.

[0004] Therefore, a flexible photovoltaic support column assembly device needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flexible photovoltaic support column assembly device to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexible photovoltaic support column assembly includes end column assemblies at both ends, several sets of intermediate column assemblies between the end column assemblies, and inclined bracing systems for assisting in fixing the end column assemblies. The end column assembly includes a column base, an end column mounted on the column base, and an end column crossbeam mounted on the end column and perpendicular to the end column. Several sets of through holes are provided on the end column crossbeam, and arc-shaped pads are embedded in the through holes. Flat pads are provided on the outer side of the arc-shaped pads, and anchors for fastening steel cables are provided. The arc-shaped pads are adjustable and movable along the through holes of the end column crossbeam.

[0008] Preferably, inclined tie plates are provided on both sides of the end column crossbeam, and the end column crossbeam adopts a circular tube cross-section structure.

[0009] Preferably, the arc-shaped pad and the flat pad are placed between the anchor and the end column beam, and the arc of the arc portion of the arc-shaped pad is consistent with the arc of the end column beam.

[0010] Preferably, a diagonal brace is also provided between the end column beam and the end column.

[0011] Preferably, the central column assembly includes a central column, a central column crossbeam disposed on the top of the central column and perpendicular to the central column, and a plurality of sets of holes for fixing steel cables are provided on the top of the central column crossbeam.

[0012] Preferably, the cross section of the central column beam is a circular tube structure, and diagonal bracing is provided between the central column and the central column beam.

[0013] The beneficial effects of this utility model are: compared with the prior art, this technical solution is suitable for flexible brackets to be installed in scenarios with large slopes; the arc plate on the end column crossbeam can be adjusted and installed within the waist hole range, so that the angle between the steel cable and the column can be adjusted with the slope, reducing the bending angle at the contact point between the anchor and the steel cable, and reducing the wear of the steel cable;

[0014] The top of the central column crossbeam has multiple rope clamp installation holes. These holes are used to install rope clamps to fix the steel cables. The rope clamps are installed in different holes to correspond to different slopes, which reduces the angle of the steel cables when passing through the central column.

[0015] A cable protection device is installed on the steel cable at the waist hole of the end column to prevent friction and wear between the steel cable and the waist hole. Attached Figure Description

[0026] To facilitate the installation of the inclined cable system 3, inclined cable lugs 14 are provided on both sides of the end column crossbeam;

[0027] To facilitate rope installation, several sets of through holes 15 are provided on the end column crossbeam 13. The end column crossbeam 13 adopts a circular tube cross-section structure.

[0028] To facilitate rope installation, an arc-shaped pad 16 is embedded in the waist hole, and a flat pad 17 and an anchor 18 for fastening the steel cable are provided on the outside of the arc-shaped pad. The arc-shaped pad 16 and the flat pad 17 are placed between the anchor 18 and the end column beam 13. The arc of the arc part of the arc-shaped pad 16 is consistent with the arc of the end column beam, and the arc-shaped pad 16 can be moved and adjusted along the waist hole 15 of the end column beam. The adjustment can be made according to the specific slope scenario of the installation. The angle can be adjusted along the waist hole 15 to reduce the angle between the steel cable and the anchor, thereby reducing the wear of the steel cable during use.

[0029] To increase the strength of the entire structure, a diagonal brace 19 is also provided between the end column beam and the end column, which serves to strengthen the structure.

[0030] In practice, to reduce friction between the end column beam and the steel cable, a clamp 5 is fitted on the outside of the steel cable placed inside the through hole 15 of the end column beam, and it is fixed by U-bolts 51 and nuts 52. This avoids friction and wear between the steel cable and the column beam when the steel cable sways, and improves the service life of the steel cable.

[0031] The central column assembly 2 includes a central column 21 and a central column beam 22 disposed on the top of the central column and perpendicular to the central column. The cross section of the central column beam is also a circular tube structure. A diagonal brace is provided between the central column and the central column beam to reinforce the central column beam. Several sets of holes 24 for fixing steel cables are provided on the top of the circular tube of the central column beam. The holes are used to install rope clamps for fixing steel cables. The rope clamps are installed in different hole positions corresponding to different slopes, reducing the angle of the steel cable when passing through the central column. The holes are provided in at least two rows and multiple sets to accommodate different angles.

[0032] The cable-stayed system 3 includes cable-stayed cables 31 that are connected to the cable-stayed lugs on both sides of the end column beam, and cable-stayed cast-in-place foundation piles 32 that are placed on the ground and connected to the cable-stayed cables.

[0033] The advantages of this utility model are that, compared with the prior art, this technical solution is applicable to the installation of flexible supports in scenarios with large slopes; the arc plate on the end column crossbeam can be adjusted within the waist hole range, so that the angle between the steel cable and the column can be adjusted with the slope, reducing the bending angle at the contact point between the anchor and the steel cable, and reducing the wear of the steel cable;

[0034] The top of the central column crossbeam has multiple rope clamp installation holes. These holes are used to install rope clamps to fix the steel cables. The rope clamps are installed in different holes to correspond to different slopes, which reduces the angle of the steel cables when passing through the central column.

[0035] A cable protection device is installed on the steel cable at the waist hole of the end column to prevent friction and wear between the steel cable and the waist hole.
