Description
Technical field
The invention belongs to renewable energy sources development technique field, relate to a kind of device for regulating direction in the horizontal axis trend energy power generation system of ocean.
Background technique
So-called ocean current mainly refers to comparatively stable flowing in seabed water channel and the straits, so-called trend mainly refers to because the regular marine stream that morning and evening tides causes, ocean current and trend mix, the trend energy accounts for major component again, both can be referred to as trend, and tidal power generating is the technology of utilizing the kinetic energy generating of ocean current.Generally need not to build a dam, generate electricity with the water turbine group.The energy of trend energy is directly proportional with the quadratic sum flow of flow velocity.Relative wave, the variation of trend energy wants much steady and regular.Trend can be with fluctuation twice change every day size and Orientation of morning and evening tides.In general, the water channel of Peak Flow Rate more than 2m/s, its trend can all have the value of actual exploitation.
The mode of utilizing of trend energy mainly is generating, and its principle is similar with wind-power electricity generation, and tidal power generating is to rely on the impact force of ocean current to make the water turbine rotation, and then drives generator for electricity generation.But because the density of seawater is about 835 times of air, and must be positioned under water, so tidal power generating exists a series of key technical problem, comprise that installation and maintenance, electric power are carried, the load in anticorrosion, the ocean environment and Safety performance etc.In addition, the design of the fixed form of tidal generating set and wind generating unit and turbine also is very different.The trend device can be mounted on the seabed, also can be installed on the bottom of buoyancy aid, and buoyancy aid is fixed in the sea by anchor chain.
Trend can be generated electricity has become the current research focus, trend can have strong, the energy density advantages of higher of predictability, but shortcomings such as flow velocity is on the low side, direction instability that subrange also exists, simultaneously abominable ocean environment bring very big difficulty also for the development of trend energy generator set.Raising unit reliability, lifting whole efficiency have become the key technical problem in the development of trend energy generator set.
The trend hydraulic generator is main two kinds of forms, and a kind of is horizontal shaft type, and a kind of is perpendicular axis type, and perpendicular axis type efficient is not high, but can accept the trend of all directions.Horizontal shaft type efficient height, but water wheels leaf fan needs along with trend turns to automatically, aim at forever trend come to, could make that generating efficiency remains on the optimum state, can bring new problem like this---the problem that power transmission cable twines.The U.S. has invented swivel joint and has solved this problem, but swivel joint expensive (100,000 dollars), the life-span is limited, is not long-term plan.In order to raise the efficiency, freely to turn to cable and be wound in a pair of contradiction.
Summary of the invention
Purpose of the present invention: without swivel joint, solve horizontal axis tidal power generating system and freely turn to the contradiction of twining with cable, in other words, expense without both expensive, just can allow horizontal axis tidal power generating system water wheel blade fan turn to automatically along with trend, forever aim at trend come to, make generating efficiency remain on the optimum state, also can not bring the winding problem of cable.
The present invention is the connection construction device that a kind of suitable horizontal axis tidal power generating system uses, and makes it automatic subtend ocean current, removes swivel joint simultaneously from, solves the winding problem of power transmission cable.Main structure is a kind of universal antitorque hollow connecting bodys that can crooked 90 degree.Principle is similar to the universal joint of automobile, but different greatly with universal joint, and it is to be made of several unit, and the centre is empty, can allow cable pass through.In the tidal power generating process, trend drives turbine and rotates, and can produce huge moment of torsion on the main shaft, and power is more big, and moment of torsion is more big, has only universal joint can transmit huge moment of torsion, can also change direction flexibly.After power generation system was installed generator and turbine, generator can to meet only direction of tide, reach the highest efficient around the axis 360 degree rotation arbitrarily of this vertical base with turbine.The rotation of generator turbine the time can produce a greatly moment of torsion, and system itself needs the opposite moment of torsion of generation offset it, and universal antitorque connection unit can bear the demand that moment of torsion greatly is competent at system.This device is the constant velocity universal joint principle, if base flange end is fixed, rotation around vertical self flange-interface direction just can not take place in generator and turbine flange end, so the direction that generator and turbine can any 360 degree subtend trends, but the winding problem of cable can not take place.
This device can very easily be attached in the horizontal axis trend energy power generation system, and is simple in structure, mechanical strength height, reliable performance, anti-seawater corrosion, tension, antitorque, in light weight, install easily, only need during use an end power generation system of this device is linked, the other end connects with base.Have cable underwater sealing interface.
The present invention mainly partly is made up of mechanical coupling part and cable connection: mechanical coupling is partly formed main universal antitorque connecting body by several hollows and is constituted the long string of a tubular, fixes an end, and the other end can bend to 90 degree to all directions.Reverse an end, the other end also and then reverses, and can transmit huge moment of torsion.Flange plate and cable underwater sealing interface and clear passage that suitable mechanical coupling is arranged at the tubular two ends.During use, the cable interface that the user can use apparatus of the present invention to carry also can not use the cable interface on this device then the use clear passage is installed user's oneself cable.
Major advantage of the present invention: needing in the horizontal axis trend energy power generation system of tuning to go for, no matter the trend device is mounted on the seabed, still be installed on the bottom of buoyancy aid, and buoyancy aid is fixed in the sea by anchor chain.Widely applicable, can need make different specifications according to different power, cost low (be about swivel joint 1/20), the life-span is long, and volume is little, is not afraid of seawater corrosion, and is easy to use, can realize non-maintaining.
