As shown in Figure 5, this cleaning device also comprises: reserve contact, be used for network remote and control the startup of this cleaning device and stop.
Start function, hold function, automatic cleaning function and Implementation for Reset Function process when working below in conjunction with this cleaning device of description of drawings:
1, starting function realizes: before the work of ball-type camera automatic cleaning apparatus, swing arm 17 and rocking bar 15 will remain in reset mode (as not at reset mode, realize with reference to reset function), reset detection switch S Q3 position on the left of promptly rocking bar 15 is pressed in and swing arm 17 are pressed in limit switch SQ1 position, left side.After RPB startup or connection reservation contact point signal send, the one, trigger among Fig. 5 and directly connect to the circuit of relay K A7 control coil from remote control or reservation contact, relay K A7 control coil gets, KA7 normally opened contact closure among Fig. 5, this moment, relay K A7 was in the self-sustaining state, the normally opened contact of KA7 among Fig. 3 is closed, and powers on to direct current machine; The 2nd, the normally opened contact of the left side limit switch SQ1 that is triggered among Fig. 4 becomes closes, normally-closed contact becomes disconnection, the control coil of relay K A3 gets, the normally opened contact of KA3 is closed and make KA3 become the self-sustaining state, thereby the control coil of relay K A1 always electric, the normally opened contact closure of KA1 among Fig. 3, normally-closed contact disconnects, electric current passes through direct current machine with the direction that flows to KA2 from KA1, and swing arm 17 drives rocking bars 15 beginnings motion from left to right.When swing arm 17 operations are depressed into right side limit switch SQ2, the normally opened contact moment closure of right side limit switch SQ2, normally-closed contact moment disconnection, this moment KA3 the control coil dead electricity, contact closed in the original self-hold circuit of KA3 disconnects, the control coil dead electricity of KA1, direct current machine outage among Fig. 3, and the control coil of Fig. 4 repeat circuit KA4 gets, the normally opened contact closing relay KA4 of KA4 enters the self-sustaining state, the control coil of relay K A2 always, the KA2 normally opened contact that triggers among Fig. 3 this moment is closed, normally-closed contact disconnects, and electric current passes through direct current machine with the direction that flows to KA1 from KA2 among Fig. 3, and swing arm 17 drives rocking bars 15 beginnings motion from right to left.When limit switch SQ1 and rocking bar 15 trigger reset detection switch S Q3 simultaneously on the left of swing arm 17 moves to, though the normally-closed contact of the KA6 among triggering Fig. 5 disconnects, but this moment the relay K A7 among Fig. 5 control coil still electric, so contact closure still of KA7 among Fig. 3; After triggering left side limit switch SQ1 simultaneously, swing arm 17 and rocking bar 15 continue motion from left to right.So realize the reciprocally swinging of automatic cleaning apparatus.
2, hold function realizes: under the normal condition, RPB stop or turn-offing reserve node signal and send after, the one, directly disconnect from remote control or reservation contact to the circuit of relay K A7 control coil, should be noted that this moment and also have one the tunnel to be that the self-hold circuit of relay K A7 is still connected, up to be rocked to left side trigger reset detection switch S Q3 when rocking bar 15 after, reset detection switch S Q3 closure, relay K A6 control coil gets, the normally-closed contact that triggers the KA6 among Fig. 5 disconnects, the self-hold circuit of relay K A7 among Fig. 5 disconnects at this moment, the contact of KA7 becomes off-state by closure among Fig. 3, the thorough dead electricity of direct current machine, this moment the camera automatic cleaning apparatus cleaning action that stops swinging, to be positioned at limit switch SQ1 position, left side static and rocking bar 15 is positioned at the static and swing arm 17 in reset detection switch S Q3 position.
3, automatic cleaning function is realized: when weather rains, experience the moisture detection sensor (being installed on the windscreen wiper sheet) of rainwater among Fig. 5 and connect triode VT1, relay K A5 control coil among Fig. 5 gets the normally opened contact closure of electric triggering KA5, relay K A7 among Fig. 5 gets, the KA7 circuit is in the self-sustaining state, trigger KA7 normally opened contact closure among Fig. 3 this moment, connect the circuit among Fig. 3, rocking bar begins in left side extreme position extreme position reciprocally swinging cleaning to the right.Light-emitting diode sends working signal simultaneously.The rain stopping time, when moisture detection sensor (being installed on the windscreen wiper sheet) is experienced less than rainwater, triode VT1 disconnects, the contact that relay K A5 control coil dead electricity among Fig. 5 triggers KA5 disconnects, but the relay K A7 self-sustaining status circuit among this moment Fig. 5 still connects, when rocking bar 15 swing triggering reset detection switch S Q3 left, triggering the KA6 normally-closed contact disconnects, the KA7 contact of triggering this moment among Fig. 3 disconnects, and the motor circuit among Fig. 3 disconnects, and rocking bar stops at reset detection switch S Q3 place.The light-emitting diode working signal extinguishes simultaneously.Wherein, the RP100k adjustable resistance of Fig. 5 plays the effect of regulating Humidity Detection sensitivity.
4, reset function realizes: if preceding rocking bar 15 of camera automatic cleaning apparatus work and swing arm 17 are not in reset mode, electrification reset button SB0(among crawl Fig. 5 is positioned at the control box of camera automatic cleaning apparatus at this moment), momentary connection is from remote control or reserve contact directly to the circuit of relay K A7 control coil, instantaneous trigger relay K A7 is in the self-sustaining state, and directly disconnect subsequently to the circuit of relay K A7 control coil from remote control or reservation contact, power on for simultaneously the direct current machine among Fig. 3.Swing arm 17 drove rocking bars 15 beginnings and began swing from left to right as if left side limit switch SQ1 among crawl Fig. 4 this moment.After swing arm 17 triggers right side limit switch SQ2, rocking bar 15 beginnings begin swing from right to left, rocking bar 15 is pushed down the reset detection switch S Q3 among Fig. 5 when being rocked to left side limit switch SQ1, the normally-closed contact that the control coil of relay K A6 among Fig. 5 gets electric triggering KA6 disconnects, the self-hold circuit of relay K A7 disconnects, the contact that KA7 among Fig. 3 was in closure state just now disconnects again, the outage of the direct current machine of Fig. 3, so rocking bar 15 promptly is parked in reset detection switch S Q3 position, left side and whole device is resetted.
More than, basic design of the present utility model and basic principle have been set forth by description of listed embodiment.But the utility model never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on the technical solution of the utility model of change all should belong to protection range of the present utility model.
