Description
Technical field
The present invention relates to a kind of power generation assembly.Specifically, be for power station using ocean currents being installed and can being swum in river, marine ocean current power generation with Free-floating platform waterborne.
Background technology
As everyone knows, the area of earth surface more than 70% all covered by ocean, has various materials and the energy that the mankind are badly in need of in the ocean, therefore, utilizes marine resources to become the trend of human lives and development in science and technology.And the exploitation of marine resources and utilization, all growing all needs to arrange large-scale job platform at sea, and this job platform can provide interim place for operating personnel's productive life and laying of equipment.
As long as traditional offshore work platform is divided into fixed type and movable two kinds.Fixed platform is normally installed column in the seabed, again operation post is arranged on the column top, it has good resistance to overturning, but, in a single day this class platform is built up and just is difficult to mobile and repeated usage, alerting ability is relatively poor, and due to the restriction that is subject to strut length and rigidity, usually only can use with interior marine site 200 meters of the depth of waters.Movable platform is exactly a floating platform at sea, and its structure is similar to the naval vessel, small volume, and draft is little, has good alerting ability, but its resistance to overturning is usually relatively poor, is not suitable for using in stormy waves larger marine site.In the last few years, people have proposed again a kind of semisubmersible platform, it is a kind of floating type platform structure, its bottom by cable and anchor tractive on sea bed, draft is large, has stability preferably, and stow cable and anchor, can utilize draw gear (as the naval vessel) to move to any marine site and use, alerting ability is stronger.But this semisubmersible platform need to be installed in its underpart a large amount of diving bodies, and the obstruction that this can be larger to the mobile generation of ocean current can not be applicable to ocean current power generation.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of ocean current power generation with Free-floating platform waterborne.This floating base station has good resistance to overturning and alerting ability, can use in darker marine site, and applicable to ocean current power generation.
For addressing the above problem, take following technical scheme:
Ocean current power generation of the present invention is to comprise buoyancy body with the characteristics of Free-floating platform waterborne, the buoyancy body bottom is connected with the floating drum of vertical layout, on buoyancy body corresponding to floating drum, hatch is arranged, cover plate is arranged on hatch, there is buoyancy compartment the position of buoyancy body bottom except floating drum, and the height of buoyancy compartment is less than the length of floating drum; The ocean current pipeline is arranged on described floating drum, and ocean current pipeline level in the floating drum is passed, and is between the barrel of the outer wall of ocean current pipeline and floating drum and is sealedly and fixedly connected, and in the floating drum of ocean current pipeline below, dividing plate is arranged, and is between dividing plate surrounding and floating drum inwall to be sealedly and fixedly connected.
The further improvement of the present invention scheme is that described floating drum has two at least, and they are side by side shape and are connected to the buoyancy body bottom, and described ocean current pipeline passes in all floating drums.A plurality of floating drums can increase the stability of whole base station, and on the ocean current pipeline in floating drum, water turbine can be installed all and carry out ocean current power generation, can improve whole electric energy generated.
The further improvement of the present invention scheme is that described ocean current pipeline has two at least, and they are side by side that shape passes floating drum.The ocean current pipe design of side-by-side can improve the stable new of base station, at ocean current during through the ocean current pipeline, makes base station almost keep impartial along the weight of ocean current pipeline longitudinal centerline both sides, and can not occur tilting.
The further improvement of the present invention scheme is to be fixed with capstan winch outside described floating drum, is wound with cable on capstan winch, and cable one end is connected on capstan winch, and the other end is connected with anchor.Utilize cable that anchor is put into the seabed, make it catch on sea bed, can make this base station be relatively-stationary both allocations that swims in, utilize impact that floating buffer action reduces seawater and wind-force to the damage that base station causes, increase its service life.
The quantity that further improvement project of the present invention is described buoyancy compartment is no less than two, and they are covered with in the buoyancy body bottom.On described buoyancy body, opening is arranged, hatchcover is arranged on opening.The quantity of the no more than buoyancy compartment of quantity of buoyancy body upper shed, and opening all is connected with a buoyancy compartment at least.In the situation that the part buoyancy compartment occur to damage water inlet, whole base station can solid flooding and make system's sinking.And the maintainer can enter the buoyancy compartment of damage by hatchcover and opening, it is keeped in repair.
Take such scheme, have the following advantages:
Because ocean current power generation of the present invention adds the structure of buoyancy compartment with Free-floating platform Bian waterborne with floating drum, the water-cup-shaped that floating drum bottom, center is into back-off is buckled in water, the bottom is seawater, top is air, and the size of floating drum can be according to the weight design of whole base station, make it be enough to support whole base station, namely when guaranteeing to provide certain buoyancy, can increase by this floating drum the stability of whole base station.And, can be used for placement devices on floating drum dividing plate under buoyancy body and in buoyancy compartment, be that most equipment all are positioned at sea following (approximately 70% weight is under the sea), the impact of wave and wind-force is very little on the impact that base station causes, and can further increase Systems balanth.Adopt the structure design of floating type, can avoid column is installed in the seabed, be convenient to movement and the repeated usage of base station, have good alerting ability.In addition, on the floating drum of the bottom of this base station, the ocean current pipeline is set, itself and speedup pipeline and water turbine are used in conjunction with, can produce larger electric energy generated in the situation that reduce the ocean current mobile obstacle, be very suitable for ocean current power generation and use.
