Mooring system for floating type new energy power generation device under shallow water condition

Abstract

The invention provides a mooring system for a floating type new energy power generation device under the shallow water condition, and belongs to the technical field of mooring systems. The floating type new energy power generation device comprises a mooring cable, a damper, a balancing weight and a buoy, one end of the mooring cable is connected with a floating type new energy power generation device on the sea surface, the other end of the mooring cable is connected with an anchor point on the seabed, the section close to the floating type new energy power generation device is a suspension section, and the section close to the anchor point is a bottom laying section; the length of the lying bottom section is 3-6 times that of the suspension section; at least one damper is arranged on the suspension section; the balancing weight is arranged on the suspension section and located below the damper. And a plurality of buoys are arranged at equal intervals and are arranged on the lying bottom section. The flexibility of the mooring cable is improved, the rigidity of the mooring cable is reduced, enough restoring force is provided for the floating type new energy power generation device, the water surface deviation amplitude of the floating type new energy power generation device in the horizontal direction is effectively restrained, and the mooring cable is particularly suitable for the floating type new energy power generation device under the shallow water condition.

Description

technical field [0001] The invention relates to the technical field of mooring systems, in particular to a mooring system for a floating new energy power generation device under shallow water conditions. Background technique [0002] Floating new energy power generation devices, such as: offshore wind turbine power generation devices, offshore photovoltaic power generation devices, offshore wave energy power generation devices and their hybrid power generation devices, etc., are also called floating new energy structures. This kind of floating new energy power generation device is subjected to external loads such as external wind, waves and currents at sea, so it needs a corresponding mooring system to connect it with the seabed. The mooring system provides restoring torque for the new energy power generation device. It can effectively improve its stability and ensure its safe work in place.

Problems solved by technology

[0004] The purpose of the present invention is to provide a mooring system for a floating new energy power generation device under shallow water conditions, aiming to solve the problem of the mooring system of the offshore floating new energy power generation device in the prior art due to the anchor chain hanging in the water in a shallow water environment. The length is relatively short, it is difficult to provide enough restoring force for the offshore floating new energy power generation device, and it is easy to cause the displacement of the power generation device to exceed the safe range.
