Detailed description of the invention
Below in conjunction with accompanying drawing, this patent is further illustrated:
As shown in Figure 1 and Figure 2, a kind of miniature piezoelectric underwater propeller mainly comprises front inlet side end cap 1, two-chamber piezoelectric fountain pump 3, mass-adjustable block 4 and drives and control circuit 5, and piezoelectric fountain pump 3 comprises the pump housing 302, circular piezoelectric vibrator 303, inlet one-way valve 304, Outlet check valves 305 and cover plate 308
The pump housing 302 arranged on left and right sides of two-chamber piezoelectric fountain pump 3 is stained with cover plate 308, the pump housing 302 is provided with left pump chamber 307, square groove and right pump chamber 306 from left to right, left and right pump chamber is symmetrically arranged in square groove both sides, and the parameter of the piezoelectric vibrator of the structure of two pump chambers, size and employing is identical.For right pump chamber 306, right pump chamber 306 is divided into unequal two pump chambers of diameter by circular piezoelectric vibrator 303, offers an entrance in the front inlet side of major diameter pump chamber, and inlet one-way valve 304 is installed in entrance, is connected outside access valve with inlet pipe; Advance end to offer an outlet, exit installation outlet check valve 305 at major diameter pump chamber, be connected with propelling end toper mouth outside outlet valve.Two-chamber piezoelectric fountain pump 3 is with bolts with front inlet side end cap 2; junction adopts seal ring protection; form intake antrum; intake antrum communicates with the inlet pipe of piezoelectric fountain pump; end cap 2 middle, front inlet side offers an advance end toper mouth 1; bell place is provided with filter layer, avoids foreign material to enter intake antrum.
As shown in Figure 2 and Figure 3, square groove is arranged on the horizontal center line of the pump housing 302, places mass-adjustable block 4 and drive and control circuit 5 in groove.Mass-adjustable block 4 is in order to keep the underwater steadily of centre of gravity of propelling unit, drive and control circuit 6 drives and control circuit comprises control circuit 501, signal generating circuit 502 and power amplification circuit 503, control circuit 501 mainly comprises microcontroller and relay, signal generating circuit 502 is formed by multi-path signal generation branch circuit parallel connection, microcontroller is according to program setting, the break-make of control relay, and then the service condition of signal generation branch road in control signal circuit for generating 502, total output voltage of conditioning signal circuit for generating, total output voltage of signal generating circuit 502 amplifies after-applied in two-chamber piezoelectric fountain pump circular piezoelectric vibrator through power amplification circuit 503.
Under alternating voltage drives, for right pump chamber 306, when the circular piezoelectric vibrator 303 of piezoelectric fountain pump 3 moves right, pump chamber volume becomes large, and pressure reduces, and inlet one-way valve 304 is opened, liquid flows in pump chamber from intake antrum, achieves the suction process of piezoelectric fountain pump; When the circular piezoelectric vibrator 303 of piezoelectric fountain pump 3 is to left movement, pump chamber smaller volume, pressure increase, Outlet check valves 305 is opened, and liquid is discharged from pump chamber, sprays fast after advancing chamber, and produce antagonistic force to propelling unit, propelling unit travels forward.
