Description
Technical field
The utility model relates to the fixing connecting bolt of a kind of Combined storage battery, and definite a kind of battery pack that says is fixedly connected with bolt automatic fastening device.
Background technique
At present, Market competition, impels communication network scale rapidly to expand, various places communication network machine room, IDC communications equipment room, Transmission Convergence machine room, base station machine room " in full flourish ", and also have the trend that increases more by force expansion.
The most basic requirement of communications network service is continuous persistent service.And the persistent service of communications network service is to be based upon on the basis of communication network device system uninterruptable power supply (UPS).
The uninterruptable power supply (UPS) of existing network communication network device system, mainly by DC uninterrupted power supply system with exchange uninterruptible power system.When civil power normal power supply, DC uninterrupted power supply system with exchange uninterruptible power system and civil power be converted to the voltage source that meets communication network device system design criteria, give communication network device system power supply, simultaneously to DC uninterrupted power supply system and the battery charging that exchanges uninterruptible power system self outfit, store electrical energy.When mains failure, battery pack electric discharge, through changing, distribute to communication network device system; While starter-generator, at generator, complete startup, export when normal, through switching, by generator, replace mains-supplied, DC uninterrupted power supply system is converted to by motor power supply the voltage source that meets communication network device systematic requirement criteria with exchanging uninterruptible power system, simultaneously to DC uninterrupted power supply system and the battery charging that exchanges uninterruptible power system self outfit, store electrical energy.
At mains failure, to completing at generator, start normal this time period of output, completely by battery pack electric discharge power supply.The length of this time period, depends on generator state, configuration, and is connected, and in the situation that diesel generating set is working properly, generally also wants ten minutes above time; And Transmission Convergence point, base station, owing to not configuring stationary power generation unit, need to allocate temporarily, because the reason of its distance, traffic aspect at least needs more than 2 hours.Besides the starting of generator set and normal operation, can not be just have 100% smoothly and perfectly safe.
Therefore, to keep good capacity be the key among communication network device system uninterruptable power supply (UPS) key to battery pack.DC uninterrupted power supply system is to use battery pack energy storage power supply in support with exchanging uninterruptible power system, all needs rectification circuit that civil power is exchanged and is converted to the required direct current of batteries charging.According to DC uninterrupted power supply system and exchange in uninterruptible power system commutating voltage level other are different, and the length of preparation time, DC uninterrupted power supply system is combined by many different single batteries from the battery pack that exchanges uninterruptible power system configuration, and generally by connecting copper bar, connect between many single batteries of composition battery pack, connect copper bar and single battery pole nut and be fastenedly connected with bolt.Adopt bolton, because bolt exists make progress tension force and ambient vibration of compression spring all the time, form and connect copper bar and turn round a little to swinging strength, after a period of time, unavoidably occur that bolton becomes flexible phenomenon.
Clamping bolt is loosening, makes to connect bad connection between copper bar and battery post, at connection part, forms contact resistance, will cause following problem
(1) battery pack is scrapped in advance
In uninterruptible power system, charging voltage is constant.Based on series circuit Ohm's law, charging voltage is shared in the existence of contact resistance, and the charging voltage that single battery is accepted is on the low side, causes undercharge, battery plate sulfuration to reduce the capacity of storage battery.
This is one of current battery pack main reason of scrapping in advance.
(2) network operation cost increases high:
According to relevant related specifications, for avoiding harmfulness clamping bolt loosening, battery pack is scrapped in advance, and at least one season will carry out checking fastening to battery pack clamping bolt comprehensively.A common carrier website is up to hundreds thousand of, battery pack quantity is more more than 1,000,000, in current network, safeguard that funds are limited, attendant, the traffic tool configure in relatively nervous situation, one season carried out checking once fastening comprehensively to battery pack bolt, can not accomplish completely.
This has just formed the situation that (capacity is lower than 80% rated capacity) generally appears scrapping in advance in battery pack, and battery pack reaches the ratio of the condition of scrapping in advance up to more than 80%.
Scrapping in advance generally appears in battery pack, has greatly increased common carrier network operation cost.According to incompletely statistics, storage battery is scrapped in advance, will cause every year operator to increase nearly ten hundred million of network operation cost.
(3) increase environmental pollution improvement's cost
Battery pack is generally scrapped in advance, and storage battery producer reclaims in the process of reprocessing battery pack, forms serious lead discharge, and local environment is polluted and strengthened, and has increased environmental pollution improvement's cost.
(4) there is fire accident hidden danger
Clamping bolt is loosening, connects bad connection between copper bar and battery post, at connection part, forms contact resistance.In the large electric current charge and discharge of storage battery process, connection part heating accumulation, causes storage battery to melt the accident of short-circuit fire.
On fire the destroying by fire in accident of common carrier storage battery occurring in recent years, clamping bolt is loosening, connects bad connection between copper bar and battery post, is one of main reason.
Summary of the invention
The purpose of this utility model is just to provide and a kind ofly prevents that clamping bolt is loosening, and device that can automatic fastening bolt, connects the bad connection occurring between copper bar and battery post, to avoid forming at connection part the contact resistance of harmfulness thoroughly to eliminate.
Scheme of the present utility model is by ratchet, ratchet sleeve and be fixedly connected with handle and form, its structural feature is to be provided with ratchet sleeve in the front side that is fixedly connected with handle, in ratchet sleeve, be provided with ratchet, the inner side of ratchet is provided with fixedly internal tooth, the outer circumference of ratchet is provided with ratchet, the middle part of ratchet is provided with rail, the middle part of ratchet sleeve is provided with sliding-rail groove, ratchet is arranged in ratchet sleeve, can in ratchet sleeve, rotate, the inner side of ratchet sleeve is provided with locking trough, in locking trough, be provided with retaining spring, retaining pin is equipped with in the front side of retaining spring, the rear side that is fixedly connected with handle is provided with Fixing clamp-seat, the upside of Fixing clamp-seat is provided with tension spring.
During use, the fixing tooth of ratchet inner side is sleeved on the fixing bolt seat of battery pack, and the Fixing clamp-seat that is fixedly connected with handle rear side is fixed on respectively on the connection copper bar of battery pack, when appearring connecting in battery pack, rocks a little copper bar, or while there is vibration because of environmental factor, ratchet, under the effect of retaining pin, resists bolt and moves to easing out direction, and promote bolt and rotate to fastening direction, play the effect of automatic fastening bolt.
