Abstract
The utility model relates to a piezoelectric hydraulic efficiency propulsion unit, belonging to the field of drive with serious electromagnetic interference. An upper cover is fixedly connected with a pump body, the periphery of a piezoelectric vibrator is supported by using an upper elastic rubber ring and a lower elastic rubber and forms a pump cavity together with the upper cover, a sealing ring is arranged between the upper cover and the pump body, the pump body is provided with a water inlet I and a water inlet II, a valve cavity is arranged between the piezoelectric vibrator and the two water inlets, the water inlet I and the water inlet II are respectively fixedly connected with an umbrella-type rubber valve I and an umbrella-type rubber valve II, and a water nozzle is formed between the two water inlets and is directly connected with the outside. The piezoelectric hydraulic efficiency propulsion unit has the advantages of simple structure, light weight, easiness in processing, large drive force and large output flow, can be used in the fields of military detection and underwater archeological study, and has better application prospects.
Description
Technical field
The utility model is to be applied under water or the hydraulic efficiency jet propulsion system of the water surface, according to the characteristic of piezoceramic, is fit to be applied in the serious driving field of electromagnetic interference.
Background technology
The anti-jet-pump that pushes away of piezoelectricity is a kind of fluid driven pumps with new material, according to the inverse piezoelectric effect of piezoceramic, makes piezoelectric vibrator produce flexural deformation, causes the variation of pump chamber, accomplishes the directed flow of fluid.The anti-plug-flow pump of piezoelectricity has the not available characteristics of conventional fluid pump.Can the pump housing, driving power, running part triplicity one can be realized characteristics such as volume is little, in light weight, power consumption is low, noiseless, no electromagnetic interference, simultaneously again can be through the micrometeor of frequency and voltage control output.Counter these characteristics that push away jet-pump of piezoelectricity are that actuator is not available under the traditional water, are another fields of actuator exploitation under water.
Summary of the invention
The utility model provides a kind of piezoelectricity hydraulic efficiency jet propulsion system, can not be in execution work of the field of electromagnetic interference and the conventional piezoelectric pump delivery is few, speed is low problem in order to solve actuator under the traditional water.
The technical scheme that the utility model is taked is: loam cake is captiveed joint with the pump housing; The piezoelectric vibrator periphery is used the elastic caoutchouc circle, the elastic caoutchouc circle supports and forms pump chamber with loam cake down; Between this loam cake and the pump housing seal ring is arranged; The pump housing is provided with water inlet one and water inlet two, between piezoelectric vibrator and two water inlets, is provided with valve pocket, captives joint umbrella shape rubber valve one and umbrella shape rubber valve two respectively at water inlet one and water inlet two places; Have the water outlet spout between two water inlets, the water outlet spout directly links to each other with the external world.
The water outlet spout of the utility model and water inlet one and water inlet two are on a conplane axis, all be positioned at below the valve pocket.
The umbrella shape rubber valve of the utility model is a shutoff valve, is whole open valve, and its spool is fixed, peripheral full open, and vertical section is a umbrella.
The utility model drives through piezoelectric vibrator, changes the valve pocket volume-variation through the piezoelectric vibrator vibration, and then changes the valve pocket internal pressure, and then fluid is formed from exporting to the directed flow process of inlet, accomplishes and sprays.Through jet water course water generates antagonistic force thrust unit is being moved.
The utility model has the advantages that: simple in structure, in light weight, be prone to processing, propulsive effort is big, delivery rate is big.Can be used for military the detection and the field of research of engaging in archaeological studies under water, application promise in clinical practice is arranged.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The water outlet spout 10 of the utility model and water inlet 1 and water inlet 2 11 are on a conplane axis, all be positioned at below the valve pocket.
The umbrella shape rubber valve of the utility model is a shutoff valve, is whole open valve, and its spool is fixed, peripheral full open, and vertical section is a umbrella.
The utility model is applied drive signal; The valve pocket volume increased when piezoelectric vibrator upwards vibrated; This moment, umbrella shape rubber valve 1 was compeled to open with umbrella shape rubber valve 2 12, and fluid can flow to valve pocket from water inlet 1 and water inlet 2 11, accomplishes the once suction state of the utility model; The pump chamber volume increases when piezoelectric vibrator vibrates downwards, and umbrella shape rubber valve 1 is compeled to close with umbrella shape rubber valve 2 12, and the fluid in the valve pocket can only be accomplished the course of injection of a pump through 10 ejections of water outlet spout.Requirement according to work is fixed on the utility model on the carrier, and carrier plays suspension effect.The utility model is gone at the water surface, also can go under water.Utilize the counteraction of the utility model jet water course on liquid, thus the motion of thrust unit.
