Other elements in the circuit do not have specific (special) requirements.
Consult Fig. 1-Fig. 4, the height of full-automatic door plate washer 1 is 40cm, and width is outer wide identical with doorframe.The bottom of baffle plate 1 connects with two hinges 3, and the other end of hinge is fixed on the bottom of doorframe both sides.The fixed pulley 10 of flexible cord on doorframe that is connected in top, baffle plate 1 right side links to each other with motor 9, transfers by motor 9 positive and negative and drives putting down and rising of baffle plate 1.Be installed on the magnet 2,4 of both sides, baffle plate 1 top, corresponding with electromagnet 6,11 positions that are installed on the doorframe both sides, the state when rising and putting down in order to control baffle plate 1.The tongue tube 12 that has normally closed contact is in order to judge the rise limit of baffle plate.A pyroelectric infrared sensor 7,8 is respectively established in the interior outside on doorframe top, and whether the someone comes in and goes out in order to detect, and realizes the automatic lifting of door shield plate 1 by control circuit.
Consult Fig. 6, Fig. 7, when unmanned turnover, automatic door plate washer 1 is in the pull-up position, be installed in the magnet 2,4 on the plate washer,, make door plate washer 1 keep stable state with the iron core adhesive that is installed in the electromagnet 6,11 on the doorframe, can not fall down, can prevent that toys such as muroid from entering.As the people when indoor or outdoors is walked close to, the pyroelectric infrared sensor 7 or 8 that is installed in about both sides, doorframe top detects the IR that human body sends, pyroelectric infrared sensor HA911 output 1 pin output pulse width is greater than the positive pulse signal of 2s among Fig. 6, and add to the base stage of triode VT1, the VT1 conducting, make the win electromagnet 6 (DC1) and second electromagnet 11 (DC2) excitation, electromagnet 6 after the excitation, 11 and the magnet 2 that is in contact with it, 4 magnetic polarity is identical, produce repulsive force, door plate washer 1 is pushed over, be convenient to transporting of personnel's walking and article.When the people leaves certain distance, pyroelectric infrared sensor 7 or 8 is surveyed the IR that sends less than human body, the 1 pin output undersuing of HA911, VT1 ends, first electromagnet 6 and second electromagnet, 11 losss of excitation, simultaneously, 2 pin of HA911 output positive pulse signal, and add to the H bridge-type motor-drive circuit of being made up of triode VT2, VT3, VT4, VT5, VT6, VT7 makes VT2, VT4, VT5 conducting, motor 9 is just changeing, by flexible cord with 1 pull-up of door plate washer.When door plate washer 1 rises to when perpendicular to the ground, the magnet 2,4 on the plate washer with the iron core adhesive that is installed in the electromagnet 6,11 on the doorframe, keeps the stable state of door plate washer 1.Be installed in the magnet 5 on the plate washer 1 simultaneously, the normally closed contact K1 that is installed in the tongue tube 12 on the doorframe is opened, among Fig. 6, the contact K1 of tongue tube disconnects the output signal of HA911, makes VT2, VT3, VT5 end, and motor 9 stops operating, and finishes pull-up.When tongue tube contact K1 disconnects, the level of trigger end 2 pin of time-base integrated circuit 555 is by high step-down,, make the monostable flipflop upset of forming by 555, become temporary stable state by stable state, 3 pin of IC3 become high level by low level, make VT7, VT6, VT3 conducting, motor 9 counter-rotatings, at this moment, door plate washer 1 still keeps the pull-up state, just flexible cord is loosened.After the monostable flipflop upset, after the rapid discharge of C1 circuit in 555 7 pin, slowly charge through R1 again.After time-delay a period of time, single-shot trigger circuit reverts to stable state by temporary stable state, and 3 pin of IC3 become low level, the motor stall.If the time that motor is just changeing is T1, the time of counter-rotating is T2, by regulating the resistance of R1, makes T2=2/3T1, and promptly when putting down plate washer next time, a door plate washer hurtles down at preceding 2/3 stroke, and back 1/3 stroke pulling motor reverses and slowly falls.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also should comprise these changes and modification interior.
If the content that is not described in detail is arranged, should be those skilled in the art's technique known in this manual, repeat no more herein.
