Description

Technical Field

[0001] This utility model relates to the field of operation and maintenance of offshore wind turbine blades, and more specifically, to a device for operation and maintenance of offshore wind turbine blades. Background Technology

[0002] Offshore wind power, as an important form of renewable energy, has developed rapidly in recent years. Due to its special working environment and complex structure, offshore wind turbines are difficult to maintain and repair, especially the blades. Therefore, maintenance and repair equipment for offshore wind turbine blades has become an important tool for improving the efficiency and safety of offshore wind farms. Under long-term wind action, offshore wind turbine blades will experience wear, corrosion, cracks, and other problems, which may even affect the operating efficiency or safety of the turbine. Therefore, regular blade inspection, cleaning, and repair are necessary. The special environment of offshore wind power, such as strong winds, waves, and distance from the shore, limits traditional maintenance methods such as manual climbing. Therefore, specially designed maintenance and repair equipment is required.

[0003] In the specific operation and maintenance of offshore wind turbine blades, the usual method is to manually climb the blades for maintenance. Although this method can be used to maintain and repair the blades, the special environment at sea is quite dangerous, making it inconvenient to carry out maintenance and repair work. Moreover, over time, dust, sea salt, and other pollutants tend to accumulate on the surface of the blades. If they are not cleaned in time, it will affect the operating efficiency of the wind turbine and make it inconvenient for operators to use. Utility Model Content

[0029] Specifically, the working process or principle of this maintenance and repair device for offshore wind turbine blades is as follows: In the typical maintenance and repair of offshore wind turbine blades 18, the usual method involves manual climbing to inspect and repair the blades. While this method can be used, the unique marine environment presents significant risks, making it inconvenient for maintenance and repair work. Furthermore, over time, dust, sea salt, and other contaminants easily accumulate on the surface of the blades. If not cleaned promptly, this can affect the wind turbine's operating efficiency and hinder operator use. Therefore, this technical solution addresses these issues. When an operator needs to perform maintenance and repair on the wind turbine blades 18, the operator first controls the offshore floating platform 11 to stabilize it. Then, the operator opens the installation door 16 and stands above the lifting platform 15. After completion, the operator... The operator can activate hydraulic cylinder 13 to rotate crossbar 14, thereby moving lifting platform 15 to the wind turbine blade 18. After completion, the operator can perform maintenance and repair on wind turbine blade 18, thereby reducing the danger of maintenance and repair and facilitating the operator's work. When the operator needs to clean wind turbine blade 18, the operator can activate booster pump 21 to extract water from water tank 2 and deliver it to spray plate 22. Installation pipe 24 can be connected to offshore floating platform 11 to deliver cleaning agents, etc., into water tank 2. At this time, spray plate 22 can spray water onto wind turbine blade 18 to clean wind turbine blade 18. By setting up water collection hopper 23, rainwater can be collected on rainy days and used when there is no rain for a long time, which is convenient for the operator. At this point, all processes are completed.

[0030] It should be noted that both the hydraulic cylinder 13 and the booster pump 21 are electrically connected to an external power source and are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
