Description
The utility model relates to a kind of by being that anode, air electrode are negative electrode with the metal, and seawater is the supply unit that battery, stepup transformer, additives for overcharge protection device and the storage battery of electrolyte formed.
Need the equipment with power supply a lot of in the ocean, as various beacon sign buoy lights etc.Used power supply major part is zinc/air alkaline battery, lead acid accumulator etc. at present, its price is expensive, volume is big, specific energy is low, goes back corrosive equipment, and the replacing of these power supplys also brings many difficulties to the user, especially under the harsh climate condition, difficulty is unimaginable especially.Designed some metal/air (or oxygen) seawater battery for this reason, once developed the supply unit (G of dissolved oxygen in magnesium metal/seawater as Norway, Haevold International power sourcesSymposium 34th 1990) and " metal-air-seawater integrated drive generator " (publication number 209878), they constitute by cell, stepup transformer and storage battery, but dissolved oxygen is limited in the former the used seawater, cause the battery volume very big, specific energy is low; Latter Ze Yin prolongs with battery discharge time, and interelectrode distance increases, and product is difficult for discharging, thereby battery performance constantly descends, and is difficult to satisfy power output steady in a long-term." seawater or salt aluminium-air cell and manufacture method thereof " (publication number 1108007) though in adopt the wedge shape anode, have some setbacks but glide, increase through reaction afterreaction face interelectrode distance, and product is difficult for getting rid of, thereby decreased performance, operating time is generally shorter, is difficult to the stable power of long-term output.
The purpose of this utility model is at the existing problem of above-mentioned battery, being intended to design a kind of anode glides smoothly with gravity easily, can take away the suspended matter that reaction produces by the seawater surge, the negative electrode that the seawater that has the capability of doing sth impacts and is difficult for being drowned, the metal/air seawater supply unit of marine growth is adhered in withstand corrosion, difficult growth, and volume is little, and specific energy is big, and the continuous operation life-span is long.
The implementation of the utility model purpose is that metal/air seawater supply unit comprises metal/air seawater cell, stepup transformer, additives for overcharge protection device, storage battery.Metal anode 3 epimeres of seawater cell are cuboid, hypomere is a sphenoid, place between two air cathodes, air cathode 9 is composited by waterproof ventilative layer, Catalytic Layer and conductive mesh, and negative electrode is glued with the reinforced plastics web plate 8 that is fixed on the battery container 4 by air chamber 7 one sides.Anode limiting pin 10 is arranged at the battery container bottom, is connected and fixed bar 1 and positioning boss 11 on the battery container around the anode.Battery container water line 6 tops have fenestra 5, and anti-infundibulate bottom leak 19 is arranged at the bottom, and there is a water storage cavity 18 the air chamber below of battery container.
The utility model is described with reference to the accompanying drawings.
Fig. 1 the utility model structural representation.
Fig. 2 the utility model constitutes block diagram.
With reference to Fig. 1, with the active metal, as magnesium alloy, aluminium alloy etc., being made into epimere is that cuboid, hypomere are the positive plate 3 of sphenoid.The appearance of epimere cuboid scribbles anticorrosion and antifouling coating, to prevent that positive plate is by sea atmosphere corrosion and outside contamination.Two inclined-planes of hypomere sphenoid are between two negative electrodes 9 after immersing seawater, and two inclined-planes are reaction surface.
Anode limiting pin 10 is arranged at battery container 4 bottoms, be connected and fixed bar 1 and positioning boss 11 on the battery container around the anode 3, it is rotatable to be connected and fixed bar 1, the positioning boss shape can be half Cylinder or hemisphere, be beneficial to anode location and because of gliding smoothly by gravitation energy after the reaction consumes, keep the distance between the anode and cathode, battery can be worked steadily in the long term.
The top of the water line 6 of battery container 4 has fenestra 5, and the fenestra width is 0.1～0.9 of a housing width, highly is 0.1～0.9 of housing height.Bottom leak 19 is arranged at battery container 4 bottoms, and it is shaped as down the big little anti-funnel-form that, and washes away the anode reaction face to utilize the seawater surge by bottom leak 19 affluxs, and the suspended matter come-up that anode reaction is generated is drained from fenestra 5.Help the continual renovation of anode reaction face like this and expose, make battery energy long-term stable operation.
Negative electrode 9 is composited by the waterproof ventilative layer that accompanies the copper currect collecting net, Catalytic Layer.The sticking bottom that is embedded in battery container 4 of negative electrode.The reinforced plastics web plate 8 on the housing of being fixed on of being close to negative electrode 9 is arranged on the battery container 4.Strengthened the ability of negative electrode resistant to salt water impact and pressure like this, made negative electrode that better leakage performance can be arranged.There is a water storage cavity 18 air chamber 7 belows of battery container, even negative electrode seepage slightly, the low amounts of water that can leak into air chamber is stored in the cavity 18 and can flood negative electrode.Battery can more adapt to maritime environment work like this.
Air inlet 2 is arranged at battery container 4 tops, and 2 places are pasted with waterproof ventilated membrane 13 at air inlet, make outside air can with air exchange in the air chamber 7, and the water that spatters on housing can not enter air chamber 7.The battery container on anode both sides is symmetrical, and two housings are connected and fixed with stainless steel connecting rod 12, and anode 3 is clipped in the middle.Stepup transformer 17 and additives for overcharge protection device, storage battery all are placed in the space of anode top battery container formation.Two cathode legs are received respectively on the positive and negative end of input of stepup transformer 17 with positive wire 14 by also tie 15 parallel connections.The output line 16 of supply unit constantly is defeated by load with electric current.
With reference to Fig. 2, below the water line of this supply unit, immerse seawater, electrochemical reaction just takes place in the anode of cell 20 and negative electrode, produce the voltage of 0.5～1.5V, through the stepup transformer 17 that constitutes by pulse oscillation circuit, switch transformed circuit, rectifying output circuit voltage is risen to 4～250V on demand, accumulators 21 chargings, storage battery confesses suitable electric current for power device 23.For making storage battery avoid overcharging, be provided with additives for overcharge protection device 22 in the device.
After this device immerses seawater, oxygen in the negative electrode consumed cabin air chambers 9, oxygen is constantly supplied with by atmosphere from air inlet, the active metal reaction generates the metallic hydrogen oxygen compound on the reaction surface of anode, be suspended in around the anode reaction face, utilize the surge of seawater, wash away the reaction surface of anode by bottom leak 19 affluxs, the anode reaction face is upgraded, the suspended matter come-up that reaction is generated is drained from fenestra 5, is fallen by reaction consumes owing to anode sphenoid point simultaneously, make anode 3 slide into anode limiting pin place, the distance between holding anode and the negative electrode under smoothly by gravity along positioning boss 11.The continuous reaction consumes of anode like this, by gravity supplys of keeping falling again, product constantly leans on seawater upwards to drain from fenestra 5 from the bottom, makes anode and cathode spacing from remaining unchanged, thereby makes cell can export required power steadily in the long term.The utility model volume is little, and specific energy is greater than 700Wh/kg, and the continuous operation life-span can reach more than 1 year, can adapt to maritime environment and use.It is a kind of well received marine supply unit.
