Abstract
The utility model relates to an automatic voltage regulator for hydraulic generator which is the accessory of the hydraulic generator, integrally comprising a four-way valve body which is connected with the water supply pipeline of the hydraulic generator. The inside of the four-way valve body is provided with a big valve core and a spring, and the upper cavity of the four-way valve body is sealed and connected with a small valve body; the inside of the small valve body is provided with a small valve core, a spring and an adjusting screw; a DC electromagnet is connected with one end of the small valve body; single-phase alternating current which is led by the hydraulic generator is connected with the electromagnet through a regulation resistance and a power converter. When the voltage is waved, the concerted action of the electromagnet and the hydraulic pressure causes the opening of the water supply pipeline to generate change, flow quantity to be changed and the rotation speed of the hydraulic generator to be changed, which reaches the stable adjustment of the voltage of the hydraulic generator.
Description
The utility model relates to a kind of annex of fluid motor, the voltage regulator on specifically a kind of hydraulic generator.
In the existing impact type minitype wheel generator that uses, generally do not establish voltage regulating device, the voltage that it produced is subjected to the influence fluctuation of impulsive force and load variations very big, very easily burns bulb and electrical appliance, thereby can not use safely.After the electric or mechanical method that adopts is arranged, rely on increase and decrease power consumption load to come regulation voltage.This class voltage regulator complex structure, cost of manufacture height, and generator always is in full load condition, machine loss and water are can loss all bigger, thereby can not extensive use.
The purpose of this utility model just provides a kind of simple in structure and with the voltage regulator of electromagnetism and hydraulic pressure automatic Regulation.
The utility model is achieved in that the discharge of leading to hydraulic generator by control regulates the water wheels rotating speed, thereby makes the corresponding change of output voltage, realizes automatic Regulation.Its structure is that big valve core and spring are housed in the vertical passage of a four-way valve body, and passage is suitable for reading to be sealed by little valve body, and end opening is sealed by end plate, and small valve core, spring and adjustment screw are housed in the horizontal channel in the little valve body, and has one and lead to external hole.Have a hole to be communicated with the upper space of big valve core in the horizontal channel of little valve body and the four-way valve body on the valve body in addition, the centre bore of big valve core is communicated with the space, upper and lower part of big valve core.There is longitudinal hole to be communicated with the big valve core lower space in the water inlet of the interconnection of four-way valve body.The single phase alternating current (A.C.) voltage of being drawn by hydraulic generator is connected to DC electromagnet behind potentiometer and rectifier, this electromagnet is connected to little valve body one side, and its mandrel withstands on the small valve core.When voltage fluctuation, the electromagnet action is moved small valve core, and each hole is communicated with, and produces pressure reduction, and the pressure by the water inlet head vertically moves big valve core, thereby controls the inflow of hydraulic generator, finally reaches the purpose of regulation voltage.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the interconnection of four-way valve body 12 is connected in by flange in the middle of the inlet channel of minitype wheel generator, its vertical passage by in big valve core 8 and spring 7 are arranged.The little valve body 15 of passage sealing-in suitable for reading, end opening sealing-in plate 17.Spring 7 withstands between little valve body 15 and the big valve core 8 on the top of big valve core.The structure of big valve core 8 is that top is a dome, the middle tubule that connects, and the bottom is the hollow circular cylinder of bottom end opening.In big valve core 8 lower hollow, be fixed with filter screen 14, in case foreign material are blocked the middle tubule of big valve core by a screwed pipe 13.In the water inlet of four-way valve body interconnection, have a hole 11, be communicated to the lower space of big valve core 8.Its space, top and the bottom is linked up in hole 10 in the big valve core.On little valve body 15, a horizontal channel is arranged, small valve core 4, spring 5 and adjustment screw 6 are wherein arranged.Passage one end sealing-in one direct current electromagnet 1, the electromagnet mandrel withstands small valve core 4, and the passage other end is sealed by plate 18.Small valve core 4 is the thick cylinders in middle thin two ends.In the horizontal channel of little valve body, there is a hole 9 to lead to the valve body outside, the position, middle part of the relative small valve core of its internal orifice.Also have a vertical hole 16 on the valve body, the vertical passage that is communicated with the horizontal channel of little valve body and four-way valve body is suitable for reading.The thick head of the right-hand member of the relative small valve core suitable for reading in hole 16 position.DC electromagnet 1 provides electric power by the direct current that the one-way communication electricity of drawing from hydraulic generator becomes behind potentiometer 3 and rectifier 2.
When big valve core 8 was in the enable possition, the current in the hydraulic generator water inlet pipe can pass through smoothly.The voltage that hydraulic generator produces acts on DC electromagnet 1 after rectification, the electromagnet mandrel produces thrust on small valve core 4, and small valve core adds certain pressure in advance by spring 5.When the voltage in the power supply circuits rose to a certain numerical value, the thrust of electromagnet 1 will be better than the precompression of spring 5 and small valve core is pushed to right-hand.The mobile of small valve core makes the water in big valve core 8 epicoeles external by hole 9 flow valves, thereby causes the pressure differential in big valve core two chambeies about in the of 8.The big valve core cavity of resorption communicates with inlet pipeline through via hole 11, and it has the pressure identical with inlet pipeline, and the water in the big valve core epicoele will 10 be replenished through the hole by cavity of resorption, thereby causes certain pressure to fall, and causes the pressure differential in two chambeies up and down.This pressure differential driving big valve core moves up and has turned down inlet pipeline.The following general who has surrendered of flow of inlet water descends rotational speed of water turbine, thereby has limited the rising of voltage.When voltage was lower than a certain numerical value, the thrust of electromagnet 1 reduced, and spring 5 promotes small valve core 4 and is moved to the left, and has closed big valve core epicoele and extraneous path.Owing to there be not flowing of water, just can not cause that in hole 10 pressure falls yet, upper and lower cavity pressure equates.Active force by spring 7 moves down big valve core, and inlet pipeline is opened greatly again, and flow strengthens, and rotational speed of water turbine improves, and the voltage of generator rises.Like this, no matter be the variation of load or the change of water condition, all can by this adjuster with voltage control within required scope.The size of regulation voltage can be undertaken by potentiometer 3 and adjustment screw 6.
The utility model has reached the automatic adjusting of voltage by the co-operating of electromagnetism and hydraulic pressure.It is simple in structure, and power consumption is little, and is easy to install and use, needn't change the structure of existing hydraulic generator, all can use for single-phase and threephase generator.
