Description
Technical field
The utility model relates to the startup field of power supplies of explosion-proof engine starting type accumulators, is specifically related to a kind of storage battery of explosion-proof actuated type.
Background technology
The a large amount of explosion-proof automobiles of the industry requirements such as mining area, petrochemical industry, fuel store, emergency repair equipment, engineering machinery etc.Its explosion-proof starting storage battery is an important component part of above-mentioned antiknock device.Current standard design is all to adopt conventional rich solution plumbic acid starting storage battery sealing to be arranged in explosion-proof iron case.Because the lead acid accumulator of rich solution can produce more hydrogen in the process discharging and recharging, also can in the process of high current charge-discharge, produce heat.So the engineering machinery of frequent start-stop also must consider that storage battery is breathed, the explosion-proof technique of heat radiation.In addition, storage battery itself is an attrition component, regularly must safeguard, change.But dismounting, explosion-proof battery of maintenance are that difficulty is very large for a common user! Become one of important topic of development explosion-proof engine with the life-span that extends starting storage battery so how to improve the reliability of equipment.
Storage environment temperature, resting period length, charge quality, the depth of discharge etc. of starting storage battery all can directly affect its life cycle.In the time that storage battery not exclusively charges, sulfation just occurs at once.Power shortage (deep discharge) is the most important factor that causes rich solution lead acid accumulator sulfation to be damaged.Due to the particularity of antiknock device, its utilization rate is well below common non-explosion-proof equipment.The automobile of the purposes of particularly speedily carrying out rescue work and engineering machinery are all for state at ordinary times in storehouse.The carelessness of environment and maintenance and cause electric deficiency phenomenon unavoidable, often must meet an urgent need and drop into and find that battery malfunction has become normality.

It has two types substantially lead acid accumulator:
rise and employand
dark circulation is used(as solar energy, IT, telecommunications etc.).The design of starting battery is to convert fast energy (as piloting engine) to according to prompt explosion, for strengthening chemical reaction ability, structure has more and thin pole plate, the internal resistance of storage battery is lower but can not deep discharge (note: a time power shortage just may cause storage battery to be scrapped, and normal operating condition, by standard: when the capacity that repeats to discharge and recharge is less than 80%, because the increase of its internal resistance can not continue to have born the heavy-current discharge task of startup); Dark circulating storage battery is exported energy relatively slowly but energy can be provided for a long time.The particularly dark circulating storage battery of colloid, it can carry out many times dark circulation electric discharge (recovery of still again charging after electric discharge completely), and the adaptation of high and low temperature environment well, few emergent gas, the excellent performance of anti-vibration, these advantages be highly suitable for antiknock device supporting, unsuitable as starting power supply but its internal resistance is relatively high.
Super capacitor is jumbo energy storage device, and its internal resistance is especially little, and internal resistance and capacity temperature influence hardly.In addition because the internal resistance of capacitor is lower, so charging is fast especially, discharging current is large, and the startup loop that is highly suitable for heavy-current discharge is used, but its shortcoming is self discharge compared with large and can not preserve for a long time after energy storage.

The storage battery of a kind of explosion-proof actuated type that the utility model provides, key technology is to adopt colloid deep cycle battery and ultracapacitor to carry out complementary combinations, parallel operation when equipment operation, during equipment downtime or stock, D.C. contactor is in disjunction state.Because the self discharge of colloid deep cycle battery is very little, the full rear discontinuous condition of high temperature is shelved 1 year, still can keep 20% electric weight (internal resistance is quite large certainly).When equipment puts into operation again, first control D.C. contactor closure (contactor being powered by colloid deep cycle battery), by two energy storage device parallel connections, the electric energy of colloid deep cycle battery is transferring on ultracapacitor of (several seconds ~ tens seconds) slowly, and enough starting currents can be obtained from ultracapacitor in the startup loop of engine.Another possibility: just in case the complete power shortage of colloid deep cycle battery.At this time, user does not need more to renew battery.As long as adopt external charger that ultracapacitor is full of, after ato unit, the D.C. contactor that closes, the colloid deep cycle battery of deep discharge still can repeatedly be restored.
Because the charge/discharge of large electric current is born by ultracapacitor, even if deeply circulate, the intrinsic flooded batteries capacity of the Capacity Ratio of colloid battery reduces half, and the storage battery of the explosion-proof actuated type of new combination still can possess more outstanding startability, longer life-span, lighter weight, less volume than the common rich solution lead acid accumulator of former design capacity.
The utility model is for the defect of prior art, adopt the dark circulation colloid battery of high internal resistance and the ultracapacitor complementary combinations of low internal resistance, make product both possess good startability, make again explosion-proof technique simple, more can extend storage battery several-fold useful life.A difficult problem for low, the frequent dismounting trouble of so influenced by ambient temperature, lengthy warehousing reliability has been readily solved.

A storage battery for explosion-proof actuated type, comprises dark circulation colloid storage battery 1, ultracapacitor 2, D.C. contactor 5, the first diode 3, the second diode 4, anti-explosion box body 9.Described dark circulation colloid storage battery 1 is in parallel with ultracapacitor 2 by contact 51, the contact 52 of D.C. contactor 5.Dark circulation colloid storage battery 1, ultracapacitor 2, D.C. contactor 5, the first diode 3, the second diode 4 are arranged on the inside of anti-explosion box body 9.By positive wire 7 and negative wire 8, the positive pole of storage battery and negative pole are drawn to the startup loop of delivering to engine in anti-explosion box body 9.6 the control end of D.C. contactor 5 53 is drawn to the control loop 61 that is sent to engine by going between in addition.When control loop 61 closures, the pull-in winding energising of D.C. contactor 5, contact 51 and contact 52 electrical communication of D.C. contactor 5, the colloid storage battery 1 that deeply circulates is in parallel with ultracapacitor 2.
The unilateal conduction performance of the first diode 3 and the second diode 4 is connected to the positive pole of ultracapacitor 2 colloid storage battery 1 that deeply circulates on 54 on D.C. contactor pull-in winding, and the pull-in winding power supply of D.C. contactor can be distinguished or be simultaneously to deeply circulate colloid storage battery and super capacitor.
There is intrinsic internal resistance 11 in dark circulation colloid storage battery 1 inside of Fig. 2, there is intrinsic internal resistance 21 in ultracapacitor 2 inside, the resistance of internal resistance 21 is far smaller than internal resistance 11, when D.C. contactor 5 is connected, when the colloid storage battery 1 that makes deeply to circulate is in parallel with ultracapacitor 2, the stored electric energy of the colloid storage battery 1 that deeply circulates can charge to ultracapacitor 2 by internal resistance 11 and internal resistance 21.By the charging of a period of time, the colloid storage battery 1 that deeply circulates is basic identical with the terminal voltage of ultracapacitor 2, and charging finishes.
When the startup loop works of engine, because the resistance of internal resistance 21 is far smaller than internal resistance 11, ultracapacitor 2 provides most starting current by internal resistance 21 for starting loop.
When engine start success, positive wire 7 and the negative wire 8 of former output have become charging input circuit.Generator will charge to ultracapacitor 2 by internal resistance 21; By internal resistance 11, dark circulation colloid storage battery 1 is charged simultaneously.Although deeply circulate, colloid storage battery 1 is basic identical with the terminal voltage of ultracapacitor 2, but owing to being far smaller than internal resistance 11 because of the resistance of internal resistance 21, so the charging current of ultracapacitor 2 is greater than the charging current of dark circulation colloid storage battery 1, in filling soon, colloid storage battery 1 slowly charging of small electric stream deeply circulates.
Out of service when equipment, control loop 61 disconnects, the contact 51 of D.C. contactor 5 and contact 52 disjunctions simultaneously.Dark circulation colloid storage battery 1 separates with charge/discharge loop.Based on the characteristic of dark circulation colloid storage battery 1, the colloid storage battery 1 that deeply circulates still can keep certain electric weight after by the stock of long period.While reusing, control loop 61 closures, D.C. contactor 5 is switched on, contact 51 and contact 52 electrical communication of D.C. contactor 5, the colloid storage battery 1 that deeply circulates is in parallel with ultracapacitor 2.Dark circulation colloid storage battery 1 shifts remaining electric energy to ultracapacitor 2, engine obtains large electric current power supply in short-term from ultracapacitor 2, and equipment just can start smoothly.
The life-span of storage battery is relevant with the number of times discharging and recharging, and larger charging or discharging current affects its life-span equally.And the technical solution of the utility model makes deeply to circulate colloid storage battery 1 always in good running status, the measure of taking is effectively extended its life-span.
The utility model has thoroughly solved the difficult problem that replacement cycle is short, startability is poor of the explosion-proof complex process of common explosion-proof starting storage battery, storage battery.
Above-described principle, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some changes, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
