Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a charging device provided in the prior art, and referring to fig. 1, in the structure of the prior art charging device, an excitation voltage regulator 10 includes a rectifying module 11, a detecting module 12, and a regulating module 13, where the regulating module 13 includes an excitation winding 131. The rectifying module 11 is configured to convert ac power into dc power, and the detecting module 12 is configured to detect an output voltage of the dc power, and modify a charging current and control a charging voltage through the adjusting module 13. Since the heat generated by the exciting winding 131 is relatively serious, the heat dissipation design of the conventional charging device is difficult. Especially for an explosion-proof charging device which needs to be provided with heat dissipation outside the generator and requires an explosion-proof housing, the problem of large heat generation of the generator makes the arrangement of the explosion-proof housing difficult to realize.
In view of the foregoing problems, an embodiment of the present invention provides a charging device. Fig. 2 is a schematic structural diagram of a charging device according to an embodiment of the present invention. Referring to fig. 2, the explosion-proof charging device provided in this embodiment includes: an explosion-proof permanent magnet generator 21, a charger 22 and a storage battery 23; the input end of the charger 22 is connected with the output end of the explosion-proof permanent magnet generator 21, the output end of the charger 22 is connected with the storage battery 23, and the charger 22 regulates the electric energy output by the explosion-proof permanent magnet generator 21 and stores the electric energy into the storage battery 23. Wherein, because this device has explosion-proof demand. An explosion-proof permanent magnet generator 21 can be used. The explosion-proof permanent magnet generator 21 may be any type of explosion-proof permanent magnet motor, and the specific model thereof is not limited in the embodiment of the present invention. Thereby, the explosion-proof performance of the charging device can be improved. For example, in some embodiments, the explosion-proof permanent magnet generator 21 can be driven by a diesel engine, and a rotating shaft of the diesel engine is connected with a rotating shaft of the explosion-proof permanent magnet generator 21. The diesel oil is combusted to do work, so that the rotating shaft of the diesel engine rotates, and power is provided for the rotating shaft of the explosion-proof permanent magnet generator 21. The rotor of the explosion-proof permanent magnet generator 21 is driven by the rotating shaft to rotate, and the coil of the explosion-proof permanent magnet generator 21 generates induced current so as to output electric power outwards. The rotor of the explosion-proof permanent magnet generator 21 may be magnetic steel, one end of the magnetic steel is an N pole, and the other end of the magnetic steel is an S pole. The charger 22 is configured to convert the ac power output by the explosion-proof permanent magnet generator 21 into dc power at a voltage required for charging the storage battery 23, so as to perform constant-voltage charging on the storage battery 23. The charger 22 may be any electronic voltage regulating device having the above functions, and the embodiment of the present invention is not limited to the specific composition and structure thereof. And a specific structure of the charger 22 will be described below. Because charger 22 is compatible high compared with the prior art, it can be purchased in the market as a general device, and does not need to be customized. The later maintenance difficulty and the maintenance cost of the charging device are greatly reduced.
For example, fig. 3 is a schematic structural diagram of a charger according to an embodiment of the present invention. Referring to fig. 3, in other embodiments, the charger 22 includes a rectifying module 221 and a voltage stabilizing module 222. The input end of the rectifying module 221 is connected with the output end of the explosion-proof permanent magnet generator 21, the output end of the rectifying module 221 is connected with the input end of the voltage stabilizing module 222, and the output end of the voltage stabilizing module 222 is connected with the storage battery 23.
The rectifier module 221 may include a rectifier bridge, and the voltage regulator module 222 may include a dc switching regulator chip and/or a low dropout regulator (i.e., LDO). The rectifier bridge may include a half-bridge rectifier bridge or a full-bridge rectifier bridge.
Fig. 4 is a schematic structural diagram of an explosion-proof control box according to an embodiment of the present invention. Referring to fig. 4, in other embodiments, there is an explosion proof requirement for the charging device. Therefore, the charging device can also comprise an explosion-proof control box 31, and the charger 22 is accommodated in the explosion-proof control box 31.
Fig. 4 shows the feature that the charger 22 is located in the explosion-proof control box 31 in the embodiment of the present invention. This is because the charger 22 is small in size and low in heat generation. And can be arranged in the explosion-proof control box 31 together with other control equipment. Compared with the existing scheme that the voltage regulator explosion-proof control box 31 is additionally arranged to accommodate the excitation voltage regulator, the embodiment of the utility model does not need to additionally arrange the voltage regulator explosion-proof box. Therefore, the structure is simple, the occupied space is small, and the cost is low.
In other embodiments, the output voltage of the charger 22 may be set to 5V-36V.
The output voltage of the charger 22 is a common voltage, and the charging device has higher practicability.
Optionally, the output voltage of the charger 22 is 28V.
In other embodiments, the explosion-proof permanent magnet generator 21 outputs three-phase alternating current.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements, combinations and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model.
