Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation technology, and in particular relates to a wind-resistant and stabilizing device for a prestressed suspension flexible support for mountain photovoltaic systems. Background Technology

[0002] Photovoltaic power generation projects require a large amount of land for photovoltaic panels. However, as the number of projects increases, available land resources decrease. With a significant increase in mountainous photovoltaic projects, the application of prestressed suspension flexible support technology is becoming increasingly widespread. When photovoltaic power generation projects are located on steep slopes with many ravines, utilizing long-span suspension technology can greatly improve land utilization and conserve land resources.

[0003] Long-span suspension technology greatly increases the usable area of ​​photovoltaic modules, but the wind-exposed area also increases. The photovoltaic modules are connected side by side on two main cables. In windy weather, due to the high altitude of the mountainous terrain, wind vibration can easily occur, causing damage to the photovoltaic modules. Summary of the Invention

[0004] The purpose of this invention is to provide a wind-resistant and stabilizing device for prestressed suspension flexible supports for mountain photovoltaic projects. This device addresses the problem that mountain photovoltaic projects using prestressed suspension flexible supports have increased wind exposure area due to the dense arrangement of photovoltaic modules connected by flexible steel cables, leading to a higher probability of damage from wind. The invention improves the stability of photovoltaic modules, reduces damage caused by strong winds, and saves on subsequent maintenance costs.

[0005] This invention provides a wind-resistant and stabilizing device for a prestressed suspension cable flexible support for mountain photovoltaic systems, comprising a load-bearing support and a load-bearing cable;

[0006] The load-bearing bracket consists of two triangular brackets connected by two connecting rods to form a conical structure. The cone tip of the load-bearing bracket is fixedly connected to the contact area of ​​the two triangular brackets by fastening bolts. The cone tip of the load-bearing bracket is provided with a cone tip ear plate and four cone tip U-shaped clips. The cone tip of the load-bearing bracket points downwards and is connected to the main cable of the photovoltaic module through the cone tip U-shaped clips.

[0007] The triangular support includes a support beam located at the bottom of the load-bearing support cone, with an upper ear plate on the upper side of the support beam and a bottom ear plate on the lower side of the support beam.

[0009] The load-bearing cable includes a transverse connecting cable, a longitudinal stabilizing cable, and a ground anchor cable. The transverse connecting cable includes a top transverse connecting cable and a bottom transverse connecting cable. The top transverse connecting cable shares the same U-shaped buckle with the main cable, and its two ends pass through the bottom ear plate of the support beam of the adjacent load-bearing support and are fixed by the U-shaped buckle. The bottom transverse connecting cable passes through the cone tip and shares the same cone tip U-shaped buckle with the longitudinal stabilizing cable. Its two ends are fixed to the upper ear plate of the support beam of the coaxial load-bearing support. The longitudinal stabilizing cable is located at the bottom of the load-bearing support and is arranged perpendicular to the transverse connecting cable. It passes through the cone tip and is fixed by the cone tip U-shaped buckle. Its two ends are connected to the ground anchor through the U-shaped buckle of the steel wire rope with a heart-shaped ring. The ground anchor cable connects the top of the load-bearing support to the ground through the U-shaped buckle.

[0010] Furthermore, the connecting rod is a galvanized metal rod.

[0011] Furthermore, the load-bearing support strut is made of galvanized angle iron.

[0012] Furthermore, the conical tip ear plate and the strut connecting ear plate are semi-circular metal rings, which are rigid connection points between two adjacent load-bearing supports.

[0026] Refer Figures 1 to 6 As shown, this embodiment provides a wind-proof and stability device for a prestressed suspension flexible support of mountain photovoltaic power generation, including an anti-load support and an anti-load cable;

[0027] The anti-load support is composed of two triangular supports 1 connected by two connecting rods 2 (M12 screws) to form a conical structure. The conical tip part of the anti-load support is fixedly connected to the contact part of the two triangular supports through a fastening bolt; a tapered tip ear plate and four tapered tip U-shaped clamps 3 are provided at the conical tip part of the anti-load support; the conical tip of the anti-load support faces downward and is connected to the main cable 8 of the photovoltaic module through the tapered tip U-shaped clamp 3;

[0028] The triangular support 1 includes a support crossbeam 11 located at the conical bottom part of the anti-load support. An upper ear plate 12 of the support crossbeam is provided on the upper side of the support crossbeam 11, and a bottom ear plate 13 of the support crossbeam is provided on the lower side of the support crossbeam;

[0029] Multiple anti-load supports are connected by anti-load support struts 4 to form an anti-load support string; both ends of the anti-load support strut 4 are provided with connection holes, the support crossbeam is provided with strut connection ear plates, and both ends of the anti-load support strut 4 are respectively connected to the tapered tip ear plates and strut connection ear plates of adjacent two anti-load supports;

[0030] The load-bearing cables include transverse connecting cables, longitudinal stabilizing cables 5 (north-south oriented cables), and ground anchor cables 6 (connecting cables between the load-bearing support and the ground anchor). The transverse connecting cables (two cables, one at the top of the load-bearing support and one at the bottom) include a top transverse connecting cable 71 and a bottom transverse connecting cable 72. The top transverse connecting cable 71 shares the same U-shaped buckle with the main cable 8, and its two ends pass through the bottom ear plate 13 of the support beam of the adjacent load-bearing support and are fixed by the U-shaped buckle. The bottom transverse connecting cable 72 passes through the cone tip and shares the same cone tip U-shaped buckle with the longitudinal stabilizing cable 5. Its two ends are fixed to the upper ear plate 12 of the support beam of the coaxial load-bearing support. The longitudinal stabilizing cable 5 is located at the bottom of the load-bearing support and is arranged perpendicular to the transverse connecting cables. It passes through the cone tip and is fixed by the cone tip U-shaped buckle 3. Its two ends are connected to the ground anchor through the U-shaped buckle of the steel wire rope with the heart-shaped ring. The ground anchor cable 6 connects the top of the load-bearing support to the ground through the U-shaped buckle.

[0031] In this embodiment, the connecting rod 2 is a galvanized metal rod, using an M12 screw, and is connected to the triangular frame by an M12 bolt, which is a rigid connection inside the load-bearing bracket.

[0032] In this embodiment, the load-bearing bracket strut is made of galvanized angle iron with connection holes at both ends, which is a rigid connection between two load-bearing brackets. The connection method is that the bottom (conical tip) ear plate of the load-bearing bracket and the top (conical bottom) ear plate of the adjacent load-bearing bracket on the north side are rigidly connected using L45*3 angle iron, and the connection method is to use M12 bolts.

[0036] The following describes the installation method of the wind-resistant and stabilizing device for the prestressed suspension flexible support of mountain photovoltaic systems.

[0037] 1. Installation of load-bearing brackets

[0038] 1.1 Assembly of load-bearing brackets

[0039] The load-bearing bracket and its supporting components (load-bearing bracket, U-shaped clips, screws, M12 bolts) are transported to the construction site for assembly. Before assembling the load-bearing bracket, it should be checked for deformation, correct ear plate orientation, and galvanization peeling. The two triangular brackets of the load-bearing bracket are assembled and fixed using two M12 screws (connecting rods). During assembly, the two M12 bolts at the bottom (conical tip) of the load-bearing bracket should pass downwards through the two through holes of the load-bearing bracket. Special attention should be paid to ensuring that the screws are tightened to allow for easy insertion and removal of the U-shaped clips at the conical tip. An installation diagram of the load-bearing bracket is attached. Figure 1 .

[0040] 1.2 Installation of load-bearing brackets

[0041] After the load-bearing brackets are assembled, they can be installed. The four U-shaped clips at the tips of the load-bearing brackets connect to the main cable 8 of the photovoltaic module, with the tips pointing downwards. During installation, the ear plates at the top of the load-bearing brackets should always face south to ensure proper strut connection between adjacent load-bearing brackets. After installation, the load-bearing brackets undergo rigid connection, i.e., the installation of the load-bearing bracket struts. The struts are connected by using L45*3 angle irons between the ear plates at the tips of the load-bearing brackets and the top (bottom) ear plates of the adjacent load-bearing brackets on the north side. The length of the L45*3 angle irons is measured and machined on-site, and the connection method uses M12 bolts. A diagram and distribution of the rigid connection of the load-bearing brackets are attached. Figure 2 As shown.

[0042] 2. Installation of load-bearing cables

[0043] The load-bearing cables include two transverse connecting cables (one at the top of the load-bearing support and one at the bottom of the load-bearing support), longitudinal stabilizing cables (north-south cables), and ground anchor cables (connecting cables between the load-bearing support and the ground anchor).

[0044] 2.1 Arrangement of transverse connecting cables

[0045] 2.1.1 Installation of top horizontal connecting cables

[0046] The transverse connecting cable 71 at the top of the load-bearing support shares the same U-shaped buckle as the main cable 8, and is located on the north side of the individual load-bearing support, as detailed in the appendix. Figure 3 , Figure 4 The top transverse connecting cable 71 of the load-bearing support is fixed at the adjacent north-side string of supports. A special ear plate (ear plate 13 at the bottom of the support beam) is provided at a specific location below the support beam for connecting the wire rope. The connection method is that the wire rope passes directly through the ear plate and is then secured using two special U-shaped clamps for wire ropes. (See attached...) Figure 5As shown, the top transverse connecting cable of the load-bearing bracket uses the ear plate at the middle position of the bottom ear plate 13 of the crossbeam of the adjacent two brackets, and so on, until the northernmost string is no longer used.

[0047] 2.1.2 Installation of bottom transverse connecting cables

[0048] The transverse connecting cable at the bottom of the load-bearing support passes through the cone tip and shares the same cone tip U-shaped clamp with the north-south longitudinal stabilizing cable. The fixing positions are at the adjacent supports at both ends of the same string of load-bearing supports, and a dedicated connecting lug plate (upper lug plate 12 of the support beam) is provided above the support beam. (See attached...) Figure 5 As shown, the fixing position of the transverse connecting cable at the bottom of the load-bearing bracket is located on the upper ear plate 12 of the bracket beam above the bracket beam.

[0049] 2.2. Installation of longitudinal stabilizing cables

[0050] The longitudinal stabilizing cable 5 is located at the bottom of the load-bearing support, running north-south. It is fixed using a U-shaped clip at the bottom of the support, with ground anchors at both the north and south ends. The connection to these anchors uses a U-shaped clip specifically designed for steel wire ropes and a heart-shaped grommets. The load-bearing support is arranged longitudinally in the photovoltaic plant area (see attached diagram for details). Figure 6 To ensure the overall stability of the load-bearing cable, a single steel wire rope can be used to run through points A, B, and C. The steel wire rope at point B and the longitudinal stabilizing cable are directly connected using a U-shaped clamp.

[0051] 2.3. Installation of ground anchor cables

[0052] In addition to a north-south running steel wire rope, the ground anchor cable also has a steel wire rope connected to the top of the end load-bearing bracket. The connection to the load-bearing bracket is a direct connection with a U-shaped buckle. Both steel wire ropes connected to the ground anchor use a heart-shaped ring with a U-shaped buckle. When using the U-shaped buckle, make sure the nut faces the direction of the main rope.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
