Abstract
The utility model discloses a double-purpose storage battery electric fan with power directly supplied by a solar battery. The electric fan consists of a solar energy low-voltage power supply system, a low-voltage direct current electric fan and a control system. According to the low-voltage direct current electric fan, electric fan blades are arranged on a shaft of a direct current motor, and the electric fan blade and the shaft are arranged in a blade hood and fixed by a fan fixing frame. According to the solar energy supply system, the solar battery and a super capacitor are connected in parallel and then electrically connected with the direct current motor. The control part comprises two control points, namely one control point of directly supplying power to the fan by using the solar battery and supplying power by a storage battery and the other point of controlling speed of the fan; according to the point of directly supplying power to the fan by using the solar battery and supplying power by the storage battery, a single-pole double-throw switch is used for switching, and two ends of the switch are connected in parallel with one diode; when the electric fan is not used, power in the solar battery is automatically charged to the storage battery and is used at night; and according to the point of controlling speed of the fan, one or two diodes are connected in series for control. According to the electric fan with power directly supplied by the solar battery, voltage is safe voltage, the storage battery is not used or seldom used, and the service life of the storage battery is prolonged; and the electric fan is widely applied to household, pasturing areas, offices and institutions.
Description
Affiliated technical field
The utility model relates to a kind of electric fan, the electric fan of especially directly supplying power with solar cell.
Background technique
At present, known electric fan great majority all are with ac-powered, and voltage 220V is dangerous, does not have the place of Ac not use.
Summary of the invention
Use the 220V Ac dangerous in order to solve electric fan, the out of use problem of areas without electricity, the utility model provides a kind of solar cell directly power supply and storage battery dual-purpose electric fan, uses solar cell for supplying power.
The utility model solves the technological scheme that its technical problem adopted: it is made up of solar energy low pressure power supply system and low-voltage DC electric fan and control system three parts.The structure of low-voltage DC electric fan is, on the axle of direct current generator, loads onto the electric fan blade, refills in blade cover, fixes with fan Fixture.Solar electric power supply system is in the place that sunlight is arranged; Be electrically connected with direct current generator after placing solar cell and super capacitor parallel connection; Will here for understanding, what use super capacitor? Mainly be because the direct current generator inrush current is big, so the big electric current in when starting is provided with super capacitor energy-storage.Control section has two control points, and one is directly power supply and storage battery power supply conversion of solar cell, and it is changed with single-pole double-throw switch (SPDT); But will about diode of parallel connection on two contacts, when without electric fan, solar cell; Can be from the trend charge in batteries; Supply use night, another is the control of fan speed, controls with one of series connection or two diodes here.Come its working procedure to be: the electricity that solar cell sent, be stored in earlier on the super capacitor, the fan of directly supplying power uses, if without electric fan, from the trend charge in batteries, when the cloudy day is used electric fan with night, throw over switch is pushed on the storage battery.
The beneficial effect of the utility model is: with the direct electric fan of power supply of solar cell, voltage is safety voltage, without storage battery with use storage battery less, in the life-span of prolongation storage battery, storage battery has the life-span, the storage battery of scrapping is also wanted befouling environment.
