Fig. 2 is the internal structure schematic diagram of this utility model protective mast.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 1 to 2; a kind of Multifunction protective mast; comprise the front shroud 1 that protection is facial; on described front shroud 1, in the position of relative workman's eyes, be provided with rectangle visual windows 2, wherein; described visual windows 2 is divided into first window 201 and Second Window 202; described first window 201 be installed with for protect eyes and high transmission lens, described Second Window is provided with liquid crystal shading lens set, the stimulation of high light while being used for blocking electric welding.
The surrounding of the outer surface of described visual windows 2 is evenly provided with the photosensitive device 12 for perception light-source brightness, described face shield also includes processing module 3, main refractive power device 5 and the auxiliary refractive power device 6 for processing the delta data that described photosensitive device 12 gathers, described data module 3 is arranged at the inner surface of described front shroud 1, with respect to the upper end of described first window.
Described processing module 3 can adopt center-control chip, adopts existing program can complete following specific works process, repeats no more.The delivery outlet of described processing module 3 is connected with described driving device 4, described driving device 4 can drive described auxiliary refractive power device 6 to pump, described main refractive power device 5 is arranged at described Second Window 202 inner surfacies, with respect to the lower end of described Second Window 202.
Described main refractive power device 5 is arranged on described face shield by regulating shaft 7 is rotatable, is used for regulating the angle of main refractive power device 5 and horizontal plane, facilitates workman's observation objects in front.
In the time that workman uses, the light intensity that described photosensitive device 12 produces when experiencing electric welding work changes, and the data that collect are passed in described processing module 3, described place module 3 receive corresponding data and described data are processed after described driving device 4 is controlled, described driving device useable electric moter, by rotating and reverse of motor, realize moving up and down of described auxiliary refractive power device 6.In the time perceiving high light, described driving device 4 drives described auxiliary refractive power device 6 to move to the relevant position of Second Window 202, eyes can catch the light source of coming in by described auxiliary refractive power device 6 and 5 reflections of described main refractive power device, in like manner, in the time that brightness weakens, described photosensitive device 12 is delivered to the data that gather in described module 3, described processing module 3 is controlled described driving device 4, and described driving device 4 is controlled auxiliary refractive power device 6 and move to the relevant position of first window 202.
The external adjusting torsion circle 9 of described regulating shaft 7, described adjusting torsion circle 9 is arranged at the side of described front shroud 1, facilitates workman to regulate described main refractive power device.
