[embodiment]
Below in conjunction with accompanying drawing, the invention will be further described, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention is a kind of motor car engine anti-flooding system, and it mainly comprises waterproofing valve and ON-OFF control circuit.Wherein waterproofing valve comprises the first waterproofing valve and the second waterproofing valve, and the first waterproofing valve is primarily of motor, gear, valve cover plate and seal ring, pipe five part composition, and the first waterproofing valve is identical with the structure of the second waterproofing valve.Whole system is made up of jointly the first waterproofing valve 4, second waterproofing valve 5 and ON-OFF control circuit 6, is connected by wire.ON-OFF control circuit 6 is arranged in operator cabin, is powered by car accumulator, and the first waterproofing valve 4 is arranged on engine intake end, and the second waterproofing valve 5 is arranged on the rear end of engine exhaust muffler 3.ON-OFF control circuit is controlled by control switch, when car owner park flame-out after, not when deenergization, long OFF position of pressing control switch, when waiting for OFF position when red, the first waterproofing valve 4, second waterproofing valve 5 be now arranged on engine intake and relief opening will close, and then closing automobile power supply.When car owner will start automobile, first opening power, length presses control switch ON position, and when ON position red light lights, the first waterproofing valve 4, second waterproofing valve 5 be now arranged on engine intake and relief opening will be opened completely, restarts automobile.
During automobile parking, if meet with water logging, the two ends waterproofing valve of motor has closed suction port and relief opening, and water cannot enter the inside of motor, reaches the object of protection motor; After water is retreated, water residual in valve can be discharged from the weep hole of valve, and before ensureing that motor starts again, the first valve 4 inside does not have water and sucks motor.
As shown in Fig. 2 (a), Fig. 2 (b), first waterproofing valve 4 comprises valve driving machine 21, first gear 22, second gear 26, the 3rd gear 18, valve cover plate 23, seal ring 24 and pipe 25, when valve driving machine 21 obtains forward 12 ~ 24Vdc direct current supply, valve driving machine 21 starts to rotate, the 3rd gear 18 be fixed on valve driving machine drives the first gear 22 and the second gear 26 to rotate, and then drive valve cover plate 23 to be rotated to " CLOSE " position by " OPEN " position, make the first valve closing; When motor 21 obtains reverse 12 ~ 24Vdc direct current supply, valve driving machine 21 starts to rotate, be fixed on the 3rd gear driven first gear 21 on valve driving machine and the second gear 26 rotates, and then valve cover plate 23 will be driven to be rotated to " OPEN " position by " CLOSE " position, make valve open.Second waterproofing valve is identical with the structure of the first waterproofing valve, and and therefore not to repeat here.
ON-OFF control circuit has the effect of control valve motor.When valve driving machine 21,27 drives valve cover plate 23,29 to rotate to " OPEN " or " CLOSE " position, now valve cover plate cannot rotate, make motor overload, control circuit can stop powering to first, second waterproofing valve because of motor overload automatically.Valve, when without power supply, can be in the state of " OPEN " or " CLOSE " all the time, can not produce the potential safety hazard in running process.
ON-OFF control circuit principle is: whole circuit is powered through connector assembly JP2 by the storage battery 2 of automobile.When switch length presses ON position, valve driving machine 21 and 27 drives the rotation of valve cover plate 23,29 to the position of " OPEN ", C3 in circuit starts charging, when continuation Push switch, valve cover plate 23,29 has arrived restriction position cannot be continued to forward to, and cause valve driving machine load to increase, whole supply current increases, in power supply line, F1 resettable fuse will disconnect voluntarily, and valve driving machine can not have power supply to stop operating yet.Now, the electric capacity C3 in circuit starts electric discharge, and the conducting of triode Q2 BC817 collector electrode, makes the red led D5 in circuit bright, and after 3 ~ 4 seconds, C3 discharge off, red led D5 extinguishes, and represents that valve cover plate 23,29 is opened and puts in place.
When switch length presses OFF position, valve driving machine 21,27 drives the rotation of valve cover plate 23,29 to the position of " CLOSE ", C1 in circuit starts charging, when continuation Push switch, valve cover plate 23,29 has arrived restriction position cannot be continued to forward to, and cause motor load to increase, whole supply current increases, in power supply line, F1 resettable fuse will disconnect voluntarily, and motor can not have power supply to stop operating yet.Now, the electric capacity C1 in circuit starts electric discharge, and the conducting of triode Q1 BC817 collector electrode, makes the red led D4 in circuit bright, and after 3 ~ 4 seconds, C1 discharge off, red led D4 extinguishes.Represent that valve cover plate 23,29 is closed to put in place; Green indicating lamp is as tutorial light at night, long bright.
