Abstract
The utility model discloses a centrifugal governor used for a dual flying hammer machine of a diesel engine, comprising two groups of flying hammers, the first group of the flying hammers are used for controlling normal work, and the second group of the flying hammers are used for controlling the quantity of oil supply at the time of overloading. The utility model overcomes the problems of inoperativeness of a governor and exhausting black smoke of an engine of the existing centrifugal governor of a full system machine at the time of overloading. The utility model capable of substituting a smoke emission limiter is particularly suitable for various types diesel engines which is not provided with the smoke emission limiter and a fuel injection angular advancer, being able to be used for a dual system machine.
Description
The utility model relates to a kind of hand tractor light auto stabilizer.
In the prior art, the hand tractor using electricity system derives from the magneto fly wheel generator, and this generator self can not be regulated output voltage, voltage, electric current all are along with hand steered dilatory engine speed raises and raises, because spread of voltage, hand drags the electricity consumption effect also to change along with the change of engine speed.During as the hand tractor night running, because of turning, Uneven road, the trail that is difficult to travel etc. all needs low speed driving, but because of generator output voltage is low excessively, front lamp, signal lamp deepening, lamplight brightness is not enough, cause the driving difficulty to the driver, even also can cause the generation of traffic accident inadequately because of lighting brightness.
The purpose of this utility model just provides a kind of energy automatic stabilisation generator output voltage, does not increase the generator loading electric current, the hand tractor light auto stabilizer that the output voltage fluctuation is little.
Solution of the present utility model is such: utilize sample circuit that generator voltage is taken a sample, by drive circuit control electronic switch, electronic switch is under the control of drive circuit, three windings of fly wheel generator can be carried out the serial or parallel connection conversion, when generator during at low speed driving, electronic switch is connected into series connection with three windings of generator, for electrical appliance provides enough voltage, when generator when running at high speed, electronic switch is controlled to be connected into parallel connection with three windings of generator, generator output voltage is reduced, for electrical appliance provides enough voltage, electric current.
The utility model has the advantages that energy automatic stabilisation generator output voltage, the output voltage fluctuation is little, and power consumption is minimum, does not increase the load current of generator, and the generator temperature rise is little.
Embodiment of the present utility model as shown in drawings.
Accompanying drawing 1 is a schematic diagram
Electric principle of the present utility model is shown in accompanying drawing 1 frame of broken lines 1, whole stabilizer is installed in the shell, 1-8 is a wiring point, only need just to be connected with electrical appliance and can to use with generator windings on request, from accompanying drawing 1 as can be seen, the utility model is to utilize sample circuit and drive circuit to control electronic switch, and electronic switch is under the control of drive circuit, three windings of fly wheel generator can be carried out the serial or parallel connection conversion, to stablize the fly wheel generator output voltage.
In the present embodiment, electronic switch is to carry out conversion by the contact of relay J, utilizes the normally closed or normally opened contact of relay J to carry out conversion, the normally-closed contact of relay J is linked to be series connection with three windings of generator, when generator speed increases, when output voltage raises, via transistor T
2, voltage-stabiliser tube D
6Sampling, oxide-semiconductor control transistors T
1Conducting, relay J get electric adhesive, and the normally opened contact adhesive of relay J connects into parallel connection with three windings of generator, and generator output voltage is descended; When generator speed decline, when output voltage hangs down, transistor (T
1, T
2) end, the relay J outage, the normal battle disconnects, and normally closed point is connected, and its contact makes three windings of generator connect into series connection, improves generator output voltage.
In the present embodiment, contact the 7, the 8th is connected with electrical appliance, as being connected with illuminating lamp, signal lamp, owing to the utility model voltage regulation result is good, also can increase to connect the charging circuit shown in the frame of broken lines 2, and storage battery is charged.
The utility model also is applicable to the voltage-regulation of vehicles such as motorcycle.
According to above-mentioned principle, the conversion of electronic switch also can adopt other electron component to realize.
Claims (3)
1, a kind of hand tractor light auto stabilizer, be to utilize sample circuit and drive circuit to control electronic switch, in order to stablize the fly wheel generator output voltage, it is characterized in that electronic switch under the control of drive circuit, three windings of fly wheel generator can be carried out the serial or parallel connection conversion.
2, hand tractor light auto stabilizer according to claim 1 is characterized in that described electronic switch is that contact by relay J constitutes, and utilizes the normally closed or normally opened contact of relay J to carry out conversion.
