Description

[Technical Field]

[0001] The present invention relates to the field of monitoring technology, and particularly to a tower monitoring device for wind power generation units. [Background technology]

[0002] The tower of a wind power unit is the core structure that supports the fan body. It is exposed to complex outdoor environments for long periods of time and must bear multiple loads such as strong winds, temperature differences, and vibrations. This makes it prone to problems such as structural fatigue, tilting, and local overheating. Since its operating status directly affects the safety and stability of the fan, real-time monitoring of the tower is extremely important.

[0003] Current technology for monitoring wind power towers primarily involves fixed sensor installation or manual patrol. Fixed sensors are typically located at specific heights or locations on the tower, limiting monitoring to a localized area. This makes it difficult to monitor structural changes along the entire tower circumference and at different heights, resulting in blind spots. Manual patrols require staff to climb the tower or use aerial work equipment, which is not only inefficient and costly, but also subject to weather and terrain constraints and safety risks associated with working at height. Furthermore, some monitoring devices use a single sensor type and can only collect a single parameter, such as temperature or vibration, preventing comprehensive assessment of the multidimensional condition of the tower structure, resulting in inaccurate fault prediction. Furthermore, current mobile monitoring devices often use single-wheel drive or tracked designs, which make it difficult to accommodate the curved structure of the tower and result in poor mobility stability. Furthermore, installation and removal are cumbersome, and they cannot flexibly adapt to towers of different diameters, resulting in limited versatility. Therefore, we propose a new type of tower monitoring device for wind power units. Summary of the Invention [Problem to be solved by the invention]

[0010] Preferably, the bolts connect the driving half ring and the driven half ring by threaded engagement, and the driving wheel and the driven wheel each have an anti-slip pattern on the outside, which increases the friction between the driving wheel and the driven wheel.

[0017] 1 and 2, a fan 18 is installed on one side of the exterior of the heat dissipation fin 11, and the fan 18 and the side case 10 are fixed to a stand. The fan 18 is used to generate airflow to improve heat dissipation efficiency.

[0018] 1 and 2, a second temperature sensor 17 is attached to one side of the exterior of the heat dissipation fin 11, and is fixedly connected to the side case 10 via a mount. The second temperature sensor 17 is used to detect the temperature of the heat dissipation fin 11, and if the temperature of the heat dissipation fin 11 is too high, the fan 18 is activated to increase the heat dissipation capacity.

[0019] Referring to FIG. 1, the bolt 3 connects the driving half ring 1 and the driven half ring 2 by threaded engagement, and anti-slip patterns 19 are provided on the outside of the driving wheel 6 and the driven wheel 8, respectively.
