Description
Technical Field
[0001] The present invention relates to the technical field of offshore building detection, and in particular to a stability detection tool for offshore wind power buildings. Background Art
[0002] With the continuous growth of the global demand for clean energy, offshore wind power generation, as a renewable energy technology with broad prospects, has developed rapidly. The construction scale of offshore wind farms has been continuously expanding, and its construction projects face many unique challenges. In the complex marine environment, the project needs to overcome the influence of harsh conditions such as wind waves, water currents, and salt fog. Moreover, offshore construction is difficult and costly, and it is particularly crucial to control the project quality. However, when the traditional construction quality acceptance methods for building engineering are applied to offshore wind farms, there are significant limitations: on the one hand, the ordinary acceptance methods do not adequately consider the particularity of the marine environment and are difficult to comprehensively evaluate the stability and durability of the foundation structure under dynamic marine loads. The installation acceptance accuracy and reliability of key equipment such as offshore wind turbines are relatively low; on the other hand, the early detection of offshore wind towers relied on manual inspections and fixed sensors, which had many defects - manual inspections were greatly affected by weather and sea conditions, with low efficiency and high costs, and it was difficult to cover the entire height of the tower barrel; fixed sensors could only monitor local areas and could not achieve dynamic scanning of large-area complex surfaces (such as the entire circumferential direction of the inner wall of the tower barrel); multi-parameter detection required the deployment of multiple independent systems, resulting in a serious data island phenomenon and making it difficult to establish a multi-physical field coupling damage model. In addition, the service environment of offshore wind towers is harsh (high salt fog, high humidity, strong vibration), and traditional detection equipment faces problems such as easy corrosion of metal materials, easy failure of hydraulic / electrical interfaces, and accelerated aging of cables due to complex wiring. Moreover, there is a lack of effective electromagnetic shielding and sealing design, significantly shortening the service life of sensors. With the development of wind power equipment towards large-scale and deep-sea, higher requirements are put forward for structural health monitoring. It is urgent to achieve dynamic acquisition of all parameters (stress, corrosion, temperature and humidity, inclination) in three-dimensional space, require the detection system to have an adaptive telescopic ability to adapt to different tower diameters and flange structures, and establish a multi-source data fusion analysis model to achieve damage evolution prediction and life assessment. However, traditional lifting devices have exposed many deficiencies in the application of wind towers. For example, the gear-rack type lifting has a crawling phenomenon resulting in insufficient positioning accuracy, the hydraulic drive system has a risk of oil leakage and its performance deteriorates in low-temperature environments. At the same time, there is a lack of modular design, and the system scalability and maintainability are poor. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

Through the rotation gear driving the rotation arc-shaped rack engaged with it in gear, through the rotation arc-shaped rack driving the convex arc-shaped telescopic block thereon, the convex arc-shaped telescopic block performs stable rotational telescoping along the arc-shaped telescopic box, so as to drive the convex arc-shaped telescopic block to perform stable vertical lifting and horizontal rotation along the inside of the offshore wind turbine tower, so as to stably horizontally rotate the convex arc-shaped telescopic block along the inside of the offshore wind turbine tower, thereby changing the telescopic adjustment assembly. Through the telescopic adjustment assembly driving the scanning assembly thereon, the inside of the offshore wind turbine tower is scanned.
[0004] Preferably, the telescopic adjustment component includes: a pair of vertical telescopic shaft tubes, a pair of convex telescopic cylinders, a pair of telescopic ring magnets, a pair of telescopic ring electromagnets, a pair of resistance regulators, a pair of sleeve buffer springs, a pair of horizontal telescopic cable shaft tubes, and a pair of horizontal telescopic cable sleeve shaft tubes; One of the pair of vertical telescopic shaft tubes is respectively inserted on both sides of the convex arc telescopic block.
