Mooring device suitable for large water level change

Abstract

The invention relates to a mooring device suitable for large water level change, and the mooring device comprises a floating structure, a mooring support, a sliding device, a buoyancy tank system and a mooring cable. A sliding straight rod of the mooring support penetrates through a sliding hole of the sliding device to ensure that the sliding device can move relative to the mooring support in the vertical direction; the buoyancy tank system and the mooring cable are both connected to the sliding device, and the buoyancy of the buoyancy tank system, the gravity of the sliding device and the tension component of the mooring cable in the vertical direction are kept balanced so as to maintain that the sliding device cannot sink to the bottom of the mooring structure. When the water level changes, the position of the floating structure moves up and down along with the water surface, the sliding device and the mooring support can slide relatively, the position of the buoyancy tank system does not change along with rising and falling of the floating structure under the constraint of the mooring cable, and therefore the tension of the mooring cable is within a certain range all the time. therefore, the excessive displacement of the floating structure caused by water level change and excessive mooring load caused by excessive tensioning of the mooring cable are avoided.

Description

Technical field[0001]The present invention relates to the field of design and manufacturing mooring system, and more particularly to a mooring apparatus suitable for a variation of large water levels.Background technique[0002]The water surface structure is floated on the water surface to withstand wind, waves, and flow against its role, resulting in displacement and deflection motion. The mooring system is typically used to restrain the water floating structure, allowing water surface floating structures to move within a certain range, and helping floating structures to resist harsh environments under extreme conditions. The composition of the mooring system is usually composed of anchor, anchor chain or an enriculata, according to the water structure function and the actual operation, other equipment such as a berth, a guide.[0003]In conventional mooring systems, the anchor position, the anchor chain length, and the moor position of the floating structure are fixed. When the water ...

Problems solved by technology

This method needs to purchase a mooring winch, which is costly. In addition, it needs to monitor the water level change and manually control the winch, so the work process is complicated.

The patent (CN108750009A) discloses a constant tension mooring system for floating structures in sea areas with large tidal ranges. Airbags and screw piles are used to keep the anchor chain tension constant when the water level changes. However, the cost of piling in the sea is too high and special equipment is required Some construction ships are not suitable for piling work due to underwater geological conditions or water depth restrictions.

The patent (CN110920808A) discloses a mooring system suitable for developing water photovoltaics in pumped storage power stations. By building a circle of cages around the photovoltaic array, the bottom of the cages is fixed on the bottom of the water, and the photovoltaic array only needs to be moored with grommets It is used on the net cage to adapt to the change of water level; this kind of scheme needs to set up a large-area net cage, and under harsh environmental conditions, in order to ensure the safety of the net cage structure, the net cage structure needs to be strengthened, and the processing and material costs are high. In addition, the net The box also needs to be restrained in the form of pile foundation, which is inconvenient for construction
