Abstract
The utility model discloses a battery charging device which comprises a power supply interface and a charging unit, wherein the power supply can be coupled with a power supply; the charging unit can charge a battery; and the charging unit is coupled with the power supply interface by an overvoltage protection module and/or a filtering module. The device can be used for charging a rechargeable battery which is not arranged in a variable pitch device operating on a fan, so that the attenuation of the electric quantity of the battery is avoided and the service life of the battery is prolonged.
Description
Technical field
The utility model relates to a kind of battery charger, relates to a kind of device for the charging of the battery case in the blower variable-pitch device specifically.
Background technology
Electric power is indispensable form of energy in daily production and the life.Traditional thermal power generation not only will consume a large amount of fossil resources, and can discharge a large amount of greenhouse gas; Though nuclear energy power generation is emission greenhouse gas not, danger very in case accident occurs, will cause irreversible destruction to environment, so various countries are the clean energy resource of representative greatly developing with the wind power generation all in recent years.
Vane change device is the vitals in the complete blower; Its effect is the rotating speed of angle with the change blade that facing the wind through adjustment blower fan blade; Can optimize the generating efficiency of complete blower at ordinary times; If blower fan generation part fault or ambient wind velocity are too fast, it can utilize the stall principle to make the blower fan blade arrive feather position again and stop operating, thereby avoids complete blower to be blown down.Vane change device is to drive the blower fan blade through built-in motor to rotate; Motor normally is energy source with the electric network source; But remote because the residing wind field of blower fan often is located in, environment is abominable, the less stable of electric network source; So the jumbo rechargeable battery of increase that vane change device of the prior art all can be extra then utilizes battery to come drive motors to accomplish the change oar action of blower fan when electric network source is lost.
Above-mentioned vane change device dispatches from the factory from produce accomplishing, and to being installed to the blower fan operation that powers on, often needs storage for a long time, transports and debugs; The decay that the electric weight of rechargeable battery can be gradually in this process, if untimely be its charging, its inner chemical composition will be ineffective gradually; Cause battery electric quantity to reduce; The life-span reduction, but in the prior art, also there is not special charging device for the charging of the rechargeable battery in the vane change device that is not fit into fan operation as yet.
The utility model content
The utility model technical problem to be solved just provides a kind of special battery charger for the charging of the rechargeable battery in the vane change device that is not fit into fan operation as yet.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of battery charger comprises the power interface that can be coupled with power supply, comprises also being the charhing unit of battery charge that this charhing unit and power interface are coupled.
Further, above-mentioned charhing unit is coupled through overvoltage protective module and/or filtration module and power interface.
Further, in charhing unit, also include temperature sensor, charhing unit is adjusted into the charging voltage of battery charge according to the temperature signal of temperature sensor collection.
Further, also comprise the indicator light that is coupled with charhing unit, described indicator light changes indication according to the charged state from charhing unit.
Further, charhing unit also is coupled through temperature relay I and power interface, and this temperature relay I is a normally opened contact, but in temperature closed its contact during more than or equal to a certain temperature; Also comprise the heater that is coupled through temperature relay II and power interface, this temperature relay II is a normally-closed contact, but breaks off its contact during more than or equal to a certain temperature value in temperature.
Further, the closed temperature of temperature relay I is 5 ℃, and the break-off signal of temperature relay II is 15 ℃.
Further, the input voltage of power interface is 220V-380V.
The beneficial effect of the utility model is:
The utility model discloses a kind of battery charger, this device can charge for the rechargeable battery that also is not installed in the vane change device that moves on the blower fan, thereby avoids the decay of battery electric quantity, prolongs its useful life.
North wind field cold weather mostly, so this battery charger can adjust charging voltage according to temperature, guarantees charging effect, and this device also includes heater, and the working temperature of assurance device is not less than 5 ℃, prolongs its useful life.
Be difficult in the wind field find stable high voltage source, so the input voltage of this battery charger elects 220V-380V as, its highly versatile conveniently uses in wind field.
