Description

Ship navigation aid device arranged on offshore wind driven generator

Technical Field

The utility model relates to boats and ships aid to navigation technical field, concretely relates to one set of boats and ships aid to navigation device who sets up on offshore wind power generation machine.

Background

China is long in coastline and wide in available sea area, the wind energy resource is rich, and the development advantage of the offshore wind power industry is remarkable. According to statistics, by 2018, nearly 120 offshore wind power projects which are publicly visible in China are obtained, and the total scale reaches 96 GW. In 2019, the UK, the Germany and the China occupy the first three digits of the global offshore wind power accumulated installed capacity, and the accumulated installed capacity accounts for more than 80% of the global total capacity. The offshore wind generating set has a large single body, such as an 8.4MW wind generating set produced by MHI Vestas with the largest single machine capacity in the world at present, the height of a hub is 115 meters, and the length of a blade is 80 meters; the blade diameter of an SL5000 series wind generating set independently developed by Huaruing wind power in China is 128 meters, 5000-degree electricity can be generated per hour under an ideal state, the electricity can be generated within the design life of 20 years according to 2300 hours of full power generation in one year, and the electricity is almost equivalent to the total electricity consumption of one day in Shanghai city.

Offshore wind farms are usually intensively arranged to contain dozens or even dozens of offshore wind turbines, and the site selection of offshore wind farms needs to meet the 'double ten' standard according to the relevant specified requirements (namely, the offshore wind farms need to have the water depth of not less than 10 meters in the sea area when the offshore distance is not less than 10 kilometers and the width of the mudflat exceeds 10 kilometers in principle). Generally, the navigation conditions of the water areas are good, and frequent activities of ships and even large ships often exist near offshore wind farms. Meanwhile, offshore wind power generators are expensive in manufacturing cost (about 1 hundred million yuan each), complex in construction and high in difficulty, and high in operation and maintenance requirements, so that once ships collide with the offshore wind power generators, particularly serious offshore accidents are usually caused. Therefore, after the offshore wind driven generator is built, the offshore wind driven generator needs to be well guaranteed and protected, and meanwhile, effective warning equipment needs to be arranged, so that irrelevant ships are prevented from approaching.

In order to ensure the navigation safety of the offshore wind turbine and the ship, a warning buoy or a light pile is usually arranged in a water area near an offshore wind farm or on an offshore wind turbine platform. But because warning buoy or light beacon are fixed and the size is less, the range is nearer and easy sheltering from, is difficult for arousing past boats and ships to pay attention to, or only can be better, closely when the weather condition, just can effectively remind. The ship speed is generally about 8-10 knots (15-18 km/h) when the ship sails near a port, the ship speed is higher when the ship sails along the sea, the ship has larger inertia, and the parking stroke of the ship of ten thousand tons generally needs about 1000m of sailing distance. Generally, when a crew drives at night or in a condition with poor visibility, the crew can choose fewer navigation aids, is less energetic than the crew in the daytime, has poor visual avoidance effect, and mainly depends on ship radars, GPS, AIS, chart and the like. If the ship needs to effectively avoid the offshore wind driven generator, a ship driver needs to discover, effectively reduce the speed or adjust the course as soon as possible and prepare for avoiding in advance.

The invention discloses an offshore wind farm safety protection system and a protection method in China patent application (publication number: CN104994354A), wherein the protection system comprises a central processing unit, an infrared sensor, a video monitoring device, a warning device and a land monitoring system, wherein the infrared sensor, the video monitoring device, the warning device and the land monitoring system are connected with the central processing unit; the system can warn the ship body or personnel to leave and protect the ship body from impacting the offshore wind farm. However, the warning effect for nearby ships is not obvious, and particularly, the warning effect for ships is limited at night or under the condition of poor visibility.
