Design and application of tower door lock for windproof wind turbine
With the rapid development of wind power industry in China, wind power generation technology is constantly innovating and improving. Among them, as an important equipment to ensure the safe operation of the wind turbine, the importance of the tower door lock of the wind turbine is becoming more and more prominent.
The windproof wind turbine tower door lock is a special door lock installed outside the wind turbine tower. Its main function is to prevent the equipment and personnel inside the tower from being affected by the external environment and ensure the safe and stable operation of the wind turbine. It not only bears all kinds of bad weather conditions from the outside, but also ensures the normal work of equipment in the tower and the safe entry and exit of maintenance personnel. Therefore, the tower door lock of windproof wind turbine needs to have excellent properties such as high strength, corrosion resistance and fatigue resistance, and can adapt to the use requirements under various extreme weather conditions.
I. Design principle
In order to meet the above requirements, the tower door lock of windproof wind turbine is generally made of high-strength alloy material, and advanced anti-corrosion technology and technology are adopted to improve its durability and service life. In addition, some special measures will be taken to increase the stability of the door lock, such as installing shock-proof devices or reinforcing ribs.
Second, the characteristics analysis
1. High strength: the tower door lock of windproof wind turbine is made of high-quality steel or aluminum alloy material, which makes it have extremely high bearing capacity and compression resistance;
2. Good corrosion resistance: enhance the resistance of metal parts to corrosive media such as water vapor and salt spray by means of surface coating and hot dip zinc;
3. Strong wind resistance: better air tightness can be achieved by optimizing the shape of the door body and configuring special locks;
4. Easy to operate: set up simple and easy-to-understand operation instruction labels and cooperate with manual/electric switch buttons to facilitate workers to quickly open and close;
5. High reliability: put into production and sales after strict testing and verification to ensure that each product can meet the expected quality standards and have a long service period.
Third, the application scenario
At present, this kind of door lock is widely used in land and offshore large-scale direct-drive permanent magnet synchronous generator systems. For example:
1. In the large-scale centralized wind field built in inland areas, sudden disasters such as sandstorm and hail are often encountered, which requires a door lock device that can effectively protect the tower from damage and avoid affecting the normal operation of the unit;
2. When it is installed on the platform infrastructure built offshore or far offshore, it is more important to pay attention to the huge pressure caused by wave impact. At this time, it is particularly important to choose an anti-collision buffer device with good sealing performance.
IV. Prospect of development trend
With the progress of science and technology and the development trend of social economy in the future, it is expected that more complete and diversified new models and specifications will become one of the mainstream development directions in the next few years; In addition, developing customized solutions for different regional characteristics will also become one of the hot topics in the industry. In a word, no matter how to change and develop, the tower door lock of windproof wind turbine has always been committed to providing users with more efficient, convenient and reliable product and service experience.
To sum up, as an important security equipment, the tower door lock of windproof wind turbine plays an important role in the whole wind power generation industry. Only by constantly carrying out technological innovation, improvement and upgrading can we better serve the overall situation of social and economic development and promote the new energy field to a higher level!
