The specific embodiment
With reference to accompanying drawing, this full-automatic rain-proof comprises every the exterior window of making an uproar the window frame 1 that plastic-steel section bar is made, the framework of window frame 1 is provided with inner chamber, and a side of framework is active face, so that after opening and battery 16, master switch 17, drive unit, damping unit, the relevant parts of opening device are installed.The upper, lower horizontal frame inner face of window frame 1 is provided with axis hole 3, the fenestrate page 2 of the interior installation of window frame 1, the rotating shaft 19 at window page 2 two ends is plugged in axis hole 3, and 2 of window pages are provided with the connecting rod 6 that makes its interlock, window page 2 can be around the shaft 19 within the scope of 90 degree vertical with parallel with window face flexible rotating.Window page 2 vertically be arranged in parallel window frame 1 is interior, and the now projection of window page 2 on horizontal plane is curved.In window frame 1, be interval with side by side multiple window pages 2, after window page 2 closures, adjacent windows page 2 overlaps successively.Each window page 2 upper ends are equipped with cylindrical projection, and movable rod 6 is provided with the circular hole corresponding with this projection, and projection is plugged in the circular hole on movable rod 6, and movable rod 6 is flexibly connected with window page 2, and each window page 2 can be realized interlock under the effect of connecting rod 6.The window frame 1 horizontal frame in top is provided with drive motors 5, drive motors 5 is provided with bent axle 25, connecting rod 6 is provided with the monolateral pulling hole 7 corresponding with bent axle 25, monolateral pulling hole 7 entirety are roughly rectangular, its one side along connecting rod 6 length directions is straight flange, relative another side is outer arcuate, its arc radius is greater than bent axle 25 radius of gyration, be that bent axle 25 lower ends are positioned at single side pushing hole 7, but bent axle 25 not with arc-shaped side one side contacts of monolateral pulling hole 7, when drive motors 5 moves, bent axle 25 is in the interior rotation of monolateral pulling hole 7, after contacting with monolateral pulling hole 7 straight flanges, can drive the straight flange one side operation of movable rod 6 to monolateral pulling hole 7.Induction installation 4 is vibration sensing switch, induction installation 4 housings are provided with wing plate 23 and sound collecting hole 24, wing plate 23 is provided with vibrating membrane 26, vibrating membrane 26 is subject to when raindrop impacts shaking, inductive switch senses signal and conducting, the main induced environment noise of sound collecting hole 24, when noise reaches certain value, inductive switch conducting.Induction installation 4 setting separation with window frame 1, can be fixed on outside window on wall.
With reference to Fig. 2, Fig. 3 and Fig. 7, the present invention is also provided with damping unit 21, and it comprises electromagnet 8, lever arm 9 and upper and lower meshing wheel (10a, 10b).The relative two sides of upper and lower meshing wheel (10a, 10b) is respectively equipped with opposite direction and energy meshing fan tooth mutually.The lower meshing 10b of wheel is contained in the rotating shaft 19 at fan window page 2 tops, and rotates and rotate with rotating shaft 19.Lever arm 9 is elastic arm, and its one end is fixed on the bottom of window frame 1 upper transverse frame, and the other end matches with electromagnet 8.Electromagnet 8 is fixed on window frame 1 stile inner side nearby, to guarantee electromagnet 8 and lever arm 9 phase adhesives.The upper meshing 10a of wheel is fixed on lever arm 9, and its position is corresponding with the lower meshing 10b that takes turns.The horizontal frame bottom of window frame 1 is provided with the travel switch 13 matching with lever arm 9, when lever arm 9 is opened, contacts with travel switch 13, and travel switch 13 is connected, and when lever arm 9 and electromagnet 8 adhesive, travel switch 13 disconnects.Travel switch 13 is connected with drive motors 5.The inner side of window frame 1 lower transverse frame is provided with approach switch 14, and this approach switch 14 is open in usual, and it is corresponding with window page 2, closure when window page 2 approaches, and approach switch 14 is connected with electromagnet 8.
By shown in Fig. 2 to Fig. 6, opening device 22 comprises opens wheel 11 and extension spring 12, opening wheel 11 is connected with the window page 2 of forms one side, the rotating shaft 19 of this window page 2 is deformed shaft, its part is polyhedron, and another part is circular, opens being provided with multiaspect body opening and pegging graft with this rotating shaft 19 of wheel 11 correspondences, open wheel 11 and be provided with outer tie point 27 with window page 2 tops, the power of stirring to window page 2 while rotating to strengthen unlatching wheel 11.Extension spring 12 two ends are connected with unlatching wheel 11 and window frame 1 respectively, and after window page 2 closures, extension spring 12 keeps certain pulling force to opening wheel 11 always; When noise disappears, electromagnet 8 power-off, after upper and lower meshing wheel (10a, 10b) opened, extension spring 12 tractives are opened wheel 11 and are rotated, and just can make window page 2 open.Window frame 1 is provided with extension spring adjusting knob 18, and rotation adjusting knob 18 can regulate extension spring 12 degrees of tightness, and then regulates it to opening the pulling force of wheel 11.
As shown in Figure 9, window page of the present invention 2 outsides are provided with solar panel 15, and battery 16 is rechargeable battery, and solar panel 15 generates electricity and charges to battery 16.Drive motors 5 can be used civil power, also can use battery to supply with the energy.On circuit, be connected to time switch 20, to set flexibly the working time.
With reference to the circuit connecting relation shown in Figure 10, the circuit that travel switch 13 is connected with drive motors 5 can be considered driving branch road; The circuit that approach switch 14 is connected with electromagnet 8 can be considered damping branch road; After driving branch road and damping branch circuit parallel connection, be connected into closed circuit with master switch 17, power supply 16, inductive switch 4 and time switch 20.The break-make of travel switch 13 is controlled by lever arm 9, and the break-make of approach switch 14 is controlled by window page 2.
The course of work of the present invention is: the present invention is as composite external window, and it is external that it is fixedly installed on room window.When there is no noise, window page 2 is pulled by extension spring 12, and entirety is unlatching shape; Now, inductive switch 4 disconnects, and does not have electric current to pass through in circuit, and electromagnet 8 is not worked, and lever arm 9 freely lifts, and travel switch 13 is connected, and approach switch 14 disconnects.When having noise or when rainy, inductive switch 4 senses that signal connects automatically, and because travel switch 13 is in on-state, now drive motors 5 rotates, and stirs movable rod 6 and moves, and window page 2 is slowly closed.When window page 2 is closed into precalculated position, approach switch 14 is connected, and electromagnet 8 is switched on, and downward adhesive lever arm 9, and now upper and lower meshing wheel (10a, 10b) is meshing, and compresses the lower meshing 10b that takes turns, and window page 2 has been turned round to damping action; When lever arm 9 is descending, travel switch 13 disconnects, motor 5 stalls, and window page 2 no longer moves; If noise or rainy continuing, electromagnet 8 is energising always, and lever arm 9 can not lift, and travel switch 13 disconnects always, and window page 2 is also closure state always.And disappear or after rain stops, inductive switch 4 disconnects when noise, electromagnet 8 power-off, lever arm 9 upwards lifts reset, and damping is eliminated, and window page 2 is got back to opening under the effect of extension spring 12.
