Description
Technical Field
The utility model relates to a wind-powered electricity generation basis anticollision technical field, especially a marine wind-powered electricity generation basis collision avoidance system that blocks ship and be close to.
Background
Under the condition of increasing shortage of energy, offshore wind power is rapidly developed as a clean renewable energy source. The foundation is used as a supporting system of an offshore structure and plays an important role in ensuring the overall safety of offshore wind power. Although the probability of the ship or the marine floater impacting the foundation is low, once the loss caused by the accident is large, the foundation or the ship body is damaged, the foundation collapses, the fan is damaged, even casualties occur, and the direct economic loss is large. The offshore maintenance operation difficulty is higher after the foundation is damaged, and adverse effects are caused to the wind turbine power generation. Therefore, the anti-collision measure for setting the foundation of the offshore wind farm is very necessary.
The existing anti-collision facilities are roughly divided into an active anti-collision facility and a passive anti-collision facility. The active anti-collision facility has the functions of warning and guiding the ship and can prevent the ship from colliding the foundation to a certain extent; the passive anti-collision facility has the functions of protecting the foundation and resisting ship collision, and when the collision is inevitable, the damage to the foundation and the ship can be reduced.
When the active anti-collision facility meets the conditions that the ship loses power, a crew does not receive a warning or does not react to the warning in time, and the like, the anti-collision guarantee can not be provided for the basis. Passive anti-collision facilities can be arranged on the foundation or around the foundation, and the anti-collision facilities (such as a fender, a floating anti-collision body and the like) arranged on the foundation can increase the anti-collision capacity of the foundation, but the foundation is not damaged, so that the construction cost and the construction difficulty are extremely high; the anti-collision facilities (such as anti-collision grouped piles, anti-collision piers and the like) distributed around the foundation can intercept ships to a great extent, so that the foundation is guaranteed not to be impacted by the ships, but in a sea area with deep water depth, the construction difficulty is high, the cost is high, the damage to the ships is large, and the maintenance after the collision is very difficult.
