Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic power engineering technical field especially photovoltaic flexible support part, specifically a kind of connection guiding device applied in cable-strut support. BACKGROUND

[0002] As one of important clean energy, photovoltaic plays a key role in global energy structure transformation. The support policy of clean energy of government of each country will continue to promote the development of photovoltaic industry, but the increasingly growing photovoltaic market is more and more limited by installation space.

[0003] Many enterprises focus on the mountainous area and water area which have not been developed yet, to cope with the market demand of constructing photovoltaic power station under complex terrain condition, flexible support design scheme becomes one of the solutions of photovoltaic construction with the advantages of large span, high clearance and less foundation. Flexible support technology is applied to small civil construction range in project, and has strong structure preloading, which greatly shortens construction period. Large span and flexible design make it have wide application range, and it can be used in complex terrain such as beach, fish pond, sewage plant, complex mountain, slope and pool, and under the premise of the vigorous advocacy of "photovoltaic+" project by the state, flexible photovoltaic support has broad application prospect.

[0004] With the technological innovation of photovoltaic industry, combined with the specific situation of application of photovoltaic flexible support in China in recent years, it is found that there are some main problems to be solved in photovoltaic flexible support. First, too large span may cause too large support disturbance, which affects the installation and power generation efficiency of photovoltaic panel. Second, the maintenance and repair of flexible photovoltaic support are more difficult than traditional support because of its complex structure and difficulty in adjustment after installation. How to design flexible support easy to maintain and repair and reduce the maintenance cost in later period also becomes one of the factors restricting its development. Third, the selection of material and durability, wear resistance and corrosion resistance in use.

[0005] Among them, the steel cable connection of flexible photovoltaic support generally adopts the connection mode of hole opening on bar and pressing with steel cable buckle, and the steel cable will form point-to-point rigid contact with sharp edge of steel plate after stress deformation, which will cause wear of steel cable under repeated change of wind load, and affect the service life of steel cable. Moreover, the steel cable buckle is installed, and the steel cable cannot be loosened again during later operation and maintenance, and the axial force of the same steel cable in different span will be unbalanced, which will generate additional force on the node and affect the safety of structure system.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] like Figures 1-4 The connecting guide device shown in the cable support mainly includes a main cable guide bushing 1, a main cable sleeve 2, and a U-bolt 3.

[0030] The main cable guide bushing 1 consists of an upper bushing for mounting above the main cable 4 and a lower bushing for mounting below the main cable. The lower surface of the upper bushing and the upper surface of the lower bushing are respectively provided with grooves that match the outer diameter of the main cable 4.

[0031] Main cable sleeve 2 is used to be fitted onto the outside of main cable guide bushing 1; the main cable sleeve 2 and the main cable guide bushing 1 are drilled and tapped on the outer surface of the vertical bushing joint to install set screw 5; the set screw consists of a rod and a nut, and the nut is used to loosen the set screw after installation.

[0032] The main cable sleeve 2 is used to connect the U-bolt 3 to the column top flange plate 13 or the secondary cable 7. In this embodiment, it is connected to the secondary cable 7.

[0033] In this embodiment: at least one side of the main cable guide sleeve 1 that mates with the main cable 4 is made of wear-resistant plastic. When the main cable sleeve 2 is connected to the secondary cable 7, a secondary cable support plate 8, which can be used as a bolt baffle, is provided below the secondary cable 7. A secondary cable positioning groove is provided in the middle of the secondary cable support plate 8. A guide protective plate 6 is provided between the secondary cable support plate 8 and the secondary cable 7. The guide protective plate 6 is made of the same material as the main cable guide sleeve 1. A hole is also drilled and tapped in the middle of the secondary cable support plate 8 to install a set screw 9.

[0034] As another installation and usage method, when the main cable sleeve is connected to the column top flange plate 13 by U-bolts 3, such as Figure 5 As shown in the figure, the column 10, column top sealing plate 11, column top stiffening ribs 12 and 13, column top mounting flanges, and flange stiffening ribs 14 are all existing technologies and will not be described in detail.

[0035] A connecting device with guiding and locking functions is added at the installation nodes of the structural system. During the initial installation, it serves as a guide and limiter, without engaging the locking function. After the flexible support structure system is installed and the steel cable stress reaches equilibrium, the locking function is activated to transfer the stress at the node to the main structure. Secondly, during the secondary tensioning of the steel cables in operation and maintenance, the set screws are loosened to ensure that the secondary tension force is evenly distributed throughout the structural system, thereby maintaining consistency between the structural system and the design.

[0036] This device is suitable for the cross-connection and fixing of steel cables, as well as the connection and fixing of steel cables to steel columns. Its advantages include: modular design, design categorized by cable diameter, assembly using standard parts, interchangeable components, and ease of on-site installation and use.
