Description
Technical field
The utility model relates to a kind of small-sized power generation device from sea current, particularly relates to a kind of ultralow startup current velocity generator for the power supply of deep-sea mooring system, belongs to the mechanical ﹠ electrical technology field.
Background technique
Because the needs of ocean development and national defence, various monitoring equipments, marine mining system, underwater robot, networking web construction and marine military installations under water, even following hydrospace station construction etc., these facilities mainly rely on the super flywheel stored energy mechanism that electric energy is provided at present.Utilize energy by ocean current generating to solve operation on the sea energy supplementary question, improve the observation technology of buoy, subsurface buoy, important application prospects is all arranged at aspects such as military affairs and oceanographic survey, marine environmental protections.Along with further carrying out of the real-time stereoscopic monitoring technology in ocean, China's autonomous type marine exploration platform increases year by year, and instrument quantity entrained on the platform is many, and the operating time is long, and power consumption is big, platform institute charged pool limited amount.Solution subaqueous survey instrument electric energy replenishes and becomes more and more urgent, resolve this key issue and can make just under water that instrument has stronger function and longer operating life, replace the weight that powered battery can also significantly reduce the cost and the mitigation system of system, the reliability of enhanced system.
Stereoscopic monitoring adopts mooring system mostly under water, and the common cloth of system is put in certain depth of water and fixed position.Along with the foundation of various deep-sea observation websites, mooring system will be multiplied under water, and entrained instrument quantity is on the increase on the platform simultaneously, and the operating time is more and more longer, the corresponding increase of power consumption.Platform institute charged pool limited amount is difficult to satisfy following marine monitoring equipment solid, real-time, round-the-clock energy needs.

According to the Bates theory, the kinetic energy that ocean current generator obtains from ocean current is that the kinetic energy of impeller import and export ocean current is poor:
In the formula, P is the energy that unit is caught, and ρ is a density of sea water, and v is a current speed, and s is the swept area of impeller, C
pBe the energy by ocean current utilization ratio.With the nominal flow rate be 0.5m/s, impeller radius 1m, Cp to get 30% be example, rated power can reach 60W.Then with the average power consumption 0.2KWh calculating every day of present real-time transmission buoy work, the separate unit electricity generating device only needs continuous operation can satisfy the demand of system to electricity consumption in 3.3 hours, and many electricity generating devices of same system configuration are the energy reliability of enhanced system greatly.
Stereoscopic monitoring adopts mooring system more under water at present, and the vertical lift technology has improved the profile survey scope of fixed point monitoring greatly, realizes the then relatively large winch under water of required power of vertical lift.Therefore, depend merely on the demand that high-energy battery can not satisfy system's long-term work electric energy.The bottom-sitting type tidal current generator is the approach that mooring system has been opened up a kind of solution electricity consumption under water, yet its shortcoming has that the alluvial of big, the anti-seabed of electricity generating device volume weight is poor, the seabed flow velocity is low etc., and these all are the major reasons of system reliability deficiency.
