Description
The present invention relates to a kind of structure of storage battery, particularly relate to the pressure conduction device that a kind of storage battery that adapts to use under the various pressure environments is used.
Up to now, the battery applications field overwhelming majority is to use in the air ambient on land, no matter external environment condition pressure is fine day or rainy being about 1 barometric millimeter of mercury, the outer container of the storage battery product of therefore, selling on the existing market is seldom considered the Application Design after external environment condition pressure sharply changes.In recent years, because land resources is poor day by day, each advanced industrial country is coincidentally the exploitation abundant more seabed resources that fixate, thereby proposed to adapt to the demand of the storage battery (as the battery that uses in the deep-sea) that various pressure environments use.
As everyone knows, the exploration of deep-sea resources and exploitation, the difficult problem that first is run into except that producing automated machine is an energy problem.For some fixed network operations, people still can resemble and lay special cable solution energy problem land.But when particularly needing mobile operation, can only rely on storage battery that the energy is provided for the deep-sea, require for this reason storage battery must adapt to tens in addition the external environment condition of a hundreds of barometric millimeter of mercury pressure in use.
In the battery design of existing deep-sea, generally be to use the shell of conventional storage battery instead high-strength material to make, perhaps adopt high-strength material to make special-purpose storage battery resistance to compression outer container, be used to resist external environment condition pressure, increase the storage battery cost thus greatly, be unfavorable for the inexpensive functional principle of civilian storage battery.On the other hand, even adopt the method for high strength resistance to compression outer container, for the requirement that thousands of meters abyssal environments use, the difficulty that realizes aspect material technology is very big, therefore only has several developed countries to obtain industry success, market price costliness at present in the world.So a kind of cheap practical method is sought in the research always of civilian storage battery industry, expect that the easy method of available industrial realization produces the deep-sea storage battery, to adapt to the 21 century demand that develops of ocean civilian industry.
The objective of the invention is to: overcome the shortcoming that existing civilian storage battery externally uses under the excessive situation of ambient pressure, or the very big and high shortcoming of cost of the storage battery manufacture difficulty that overcomes existing employing high strength resistance to compression outer container, thereby provide a kind of be applicable under the deep-sea use, all adopt conventional material manufacturing, the pressure conduction device that the simple storage battery of manufacture craft is used.
The object of the present invention is achieved like this:
The pressure conduction device that storage battery provided by the invention is used, comprise a common storage battery outer container, on the additional filling opening of storage battery outer container or the decompression valve port of storage battery (former pressure-reducing valve cap is removed), connect firmly a pressure conducting piece, and the bottom of pressure conducting piece contacts fully with the electrolyte of internal storage battery.
Described pressure conducting piece comprises pressure conductive sheet or pressure transmission pipe; Pressure conductive sheet or pressure transmission pipe can with rubber or other be as bigger, the acidproof and alkaline-resisting material of coefficient of elasticity such as plastics; , note adaptation requirement when selecting material to battery electrolyte acid (or alkali) degree.
Described pressure conductive sheet top exposes shape in the storage battery exterior portion and can be circle, ellipse, square, rectangle, trapezoidal, polygonal limit shape and other geometry, and its area is greater than 1mm
2, thickness is greater than 0.01mm.
Described pressure conductive sheet directly connects firmly on the additional filling opening of open type storage battery outer container, and the bottom surface of pressure conductive sheet touches the internal storage battery electrolyte; Perhaps the pressure conductive sheet connects firmly indirectly and replenishes on the filling opening, be that a hole is opened in the center of circle promptly with the center that replenishes the filling opening blind nut, the size in hole is similar to replenishes the filling opening diameter, the pressure conductive sheet is fixing within it, cover this hole, blind nut is fixed on and replenishes on the filling opening, and the bottom surface of pressure conductive sheet touches the internal storage battery electrolyte.Described hole can be the hole of geometries such as circular, square, ellipse.
The cross section of described pressure transmission pipe is greater than 1mm
2, its length is greater than 1mm, is shaped as circle, ellipse, square, rectangle, trapezoidal and other geometry.
Described storage battery outer container comprises open type or enclosed accumulator outer container; When a pressure transmission pipe connects firmly at enclosed accumulator outer container decompression valve port (former pressure-reducing valve cap is removed) when going up, the afterbody of pressure transmission pipe touches the internal storage battery electrolyte, and electrolyte is filled to pressure transmission pipe exposes in the pipe outside storage battery, the top of its pressure transmission pipe is lived with a seal sealing and fixing.Described seal is identical with the material of pressure transmission pipe.Described seal is that a diaphragm seal directly seals, but perhaps does seal with the piston of opening a supplier, and plug is in the decompression valve port, and interface is filled the pressure-resistant material of common waterproof gas-tight.The material of piston should be selected for use with the material of pressure transmission pipe identical, and as rubber or other elasticity acid resisting material preferably, sealing means can adopt the form that is connected that rotation is connected or other makes things convenient for secondary to use.
Fill with traditional storage battery electrolyte lean solution and general rich solution is filled and different is, must change abundant rich solution filling into after using this device instead.When adopting pressure conductive sheet producing device, the electrolyte of internal storage battery must be filled to the pressure conductive sheet and contact fully; When adopting the pressure transmission pipe producing device.
To the utilization of apparatus of the present invention, the type selecting of battery electrolyte is very important, does not have substantially when requiring electrolyte to discharge and recharge that any gas is separated out, the coefficient of expansion of charging and discharging state is minimum.To traditional lead acid accumulator, if the supporting unavoidable bubbing of charging method, the device that is connected of pressure transmission pipe or pressure conductive sheet and storage battery can be made into and can supply the secondary opening form.Like this, put pressure transmission pipe (sheet) in open state when charging, make it bubbing, storage battery is full of electricity back resealing pressure conduction device to be used.This method is owing to repeat the opening and the sealing of pressure conduction device during accumulator cell charging and discharging, and strength of discharge can only be limited in little current range, makes troubles to practical application.Therefore this device convenient and practical at lead acid accumulator need add in electrolyte sulfuric acid and adsorb additive by force or use colloidal electrolyte instead, to adapt to apparatus of the present invention to electrolytical above-mentioned requirements.
To the utilization of this device, also be a considerable problem as the pole plate compressive resistance of internal storage battery main structure body.In the manufacture craft of conventional chloride plate, the polar board surface active material after the pickling energising changes into is a kind of loose body, uses to be out of question under atmospheric pressure environment.But when using in conjunction with this device, because pressure transmission pipe (sheet) is passed to the internal storage battery structure with external pressure, when external pressure strengthens n times (n＞1), the internal storage battery pole plate also will bear n multiplication of voltage power, active material solidifies bad pole plate might quicken to come off, thereby the capacity and the life-span of storage battery influenced to some extent.Therefore, must be when using this device to the active material state of cure requirement to some extent of accumulator plate, in principle, the compression resistance intensity of pole plate operate as normal will determine storage battery pressure environment life-span of using externally.
This device is not only applicable to use extraordinary sulfuric acid, chemical colloid to make electrolytical lead accumulator, its method principle be equally applicable to any use acidity, alkalescence, neutral electrolyte and use various material pole plates (or its distortion) once or secondary cell.
The advantage of apparatus of the present invention is:
