Description

Deep sea low temperature is against control formula oceanographic observation battery flat
Technical field
The invention belongs to oceanographic observation deep sea low temperature particular surroundings for electrical domain, and in particular to a kind of deep sea low temperature is against control formula Oceanographic observation battery flat.
Background technique
In recent years, the world is with population increase, and environmental degradation, land resource is gradually deficient, increasingly to the research at deep-sea Attention by all circles.In order to preferably develop, using with protection Ocean energy, it is necessary to obtain on a large scale, essence True various ocean wave parameter data need to carry out a large amount of preventing seabed base, the observation of subsurface buoy deep-sea, this just be unable to do without battery and provides the energy Power.
Ocean temperature changes generally between -2 DEG C~30 DEG C.Directly observation show world ocean ocean temperature generally with The increase of depth and reduce, in low latitudes sea area, 350m is maximum with the rate that shallowly reduces, 12 DEG C of 350m characteristic temperature；350- The rate that 2000m reduces is larger, and 2 DEG C of 2000m characteristic temperature；The rate that 2000-4000m reduces is relatively slow, 4000m characteristic temperature 1 ℃；4000m is held essentially constant with deep.In other words, 500m is with depth, and water temperature is substantially all at 10 DEG C or less；1000m is with depth, water Temperature is substantially all at 5 DEG C or less；2000m is with depth, and water temperature is substantially all at 2 DEG C or less.
The oceanographic observation battery that can be used at present, under cryogenic conditions as deep-sea, discharge capability can only reach mostly It is even lower to 50%, can reach individually 70% again because safety is not easy to use.Since battery altering is observed in deep-sea ocean It is not easy very much, the battery flat of conventional batteries discharge capability can be guaranteed under cryogenic by being badly in need of invention, ensure oceanographic observation It is normally carried out.
Summary of the invention
This invention address that improving the discharge capability of conventional batteries under the conditions of deep sea low temperature, a kind of inverse control of deep sea low temperature is invented Formula oceanographic observation battery flat.The invention utilizes battery work based on understanding in depth to deep-sea observing environment and battery discharge characteristic Make the heat phenomenon in discharge process, collecting, protect, accumulating these originally is the heat of side effect, best in conjunction with what is specifically observed Discharge cycle control, uses the reverse holding of battery operating discharge temperature under the conditions of deep sea low temperature, and increase initial temperature control, height Through-hole and limit temperature control are pressed, discharge capability of conventional batteries under the conditions of deep sea low temperature is improved 30%, is obviously improved deep-sea sight It surveys efficiency and reduces observation cost.BROAD SUMMARY includes:
1) the gold drum design of battery flat body: the compatibility of the convenience and polytypic battery that are accommodated in view of battery Property, battery flat body takes drum-shaped, if its a height of h, diameter d, wall thickness δ；Consider from volume controlled and buoyancy control, needs Want biggish d and lesser δ；But in order to resist Deep-sea high voltage, d is the smaller the better, and δ is the bigger the better；In order to find optimization scheme, It calculates comparing the result is that selectedThat is diameter height ratio meets golden section.
2) the double-deck thermal insulation of battery flat wall body designs (first layer preservation and controlling: thermal insulation): the outer wall of battery flat bilayer wall body For resisting hydraulic pressure, in order to cope with Deep-sea high voltage, and reduce wall body weight, outer wall uses high-low temperature resistant, anti-seawater corrosion, height Intensity, low-density, non-magnetic titanium material, and technique is emptied using stud；Inner wall is used for thermal insulation, for effective thermal insulation and reduces Cabin weight, inner wall uses transparent, high-low temperature resistant, pollution-free, non-toxic and tasteless and performance stabilizing polyurethane material, and uses thin cylinder Integrated forming technique.
