Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a flexible photovoltaic cable anchoring device and method with automatic adjustment and monitoring functions. Background Art

[0002] In the field of photovoltaic power generation technology, flexible photovoltaic brackets are widely used in various complex terrains and scenarios due to their flexibility and strong adaptability. Flexible photovoltaic brackets usually use prestressed cable structures to support photovoltaic panels to ensure that photovoltaic panels can stably receive sunlight and convert it into electrical energy. However, during long-term operation, flexible photovoltaic brackets with prestressed cable structures are prone to cable relaxation, which not only affects the safety and stability of photovoltaic panels, but also reduces the power generation efficiency of photovoltaic power stations.

[0003] In the prior art, in order to solve the problem of cable tension relaxation of flexible photovoltaic brackets, the method of manually checking and adjusting the cable tension regularly is usually adopted. This method is not only time-consuming and labor-intensive, but also difficult to ensure accurate control of the cable tension. Especially under severe weather conditions, such as strong winds, heavy rains, etc., the difficulty and danger of manually adjusting the cable tension will be greatly increased. In addition, the prior art also lacks a device that can effectively monitor the cable tension state and automatically adjust it, resulting in the problem of cable tension relaxation often being difficult to detect and deal with in a timely manner.

[0004] Specifically, the cables of flexible photovoltaic brackets in the prior art are usually fixed to the brackets through anchoring devices, and the design of the anchoring devices often only considers the fixing and supporting functions of the cables, while ignoring the dynamic adjustment and monitoring requirements of the cable force. Therefore, during long-term use, due to environmental factors, material aging and other reasons, the cable force will gradually relax, thereby affecting the stability and safety of the photovoltaic panels. Although there are some cable force adjustment devices on the market, these devices are usually complex in structure, cumbersome to operate, and difficult to achieve automated and intelligent control.

[0005] In summary, the flexible photovoltaic bracket in the prior art has obvious deficiencies in cable force adjustment and monitoring, and an anchoring device that can automatically adjust the cable force and monitor the cable force state in real time is urgently needed to improve the safety and reliability of the flexible photovoltaic bracket. The present invention is proposed based on this technical background, aiming to solve the problems existing in the prior art through innovative design and provide strong support for the development of flexible photovoltaic power generation technology.
