Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Examples
Referring to fig. 1-5, a self-dimming privacy shutter comprises a square frame body 1, wherein a plurality of leaf plates 2 are fixed in the frame body 1 at equal intervals, each leaf plate 2 inclines 45 degrees relative to a horizontal plane, the effect of preventing the indoor privacy from being peeped outdoors is achieved, a photovoltaic power generation sheet is fixed on one side, facing outdoors, of each leaf plate 2, the photovoltaic power generation sheets are mutually connected in parallel to form a power supply pack, and a photosensitive resistor 7 is fixed on one photovoltaic power generation sheet;
a sliding groove 4 is formed in each leaf plate 2, frosted glass 3 is fixed on one side, away from the photovoltaic power generation sheet, of each sliding groove 4, a striped plate 5 capable of adjusting the reflection amount of the frosted glass is connected in each sliding groove 4 in a sliding mode, and a metal spring 6 is fixed on the inner wall of each sliding groove 4 and the striped plate 5;
a plurality of springs 6 are connected in parallel with photoresistor 7, power pack series again after each other, and both sides all are fixed with the light screen 8 of bar about the inner wall of framework 1, and light screen 8 can shelter from the gap department between the most upper page or leaf board 2 and the framework 1 with the most lower page or leaf board 2, further avoids outdoor spying indoor privacy.
The rough glass 3 faces to the semi-permeable membrane glass with one side being rough and uneven and the other side being smooth indoors, light irradiated on the rough glass 3 is guaranteed to be diffused and reflected indoors, light pollution caused by local light beam irradiating to equipment is avoided, a plurality of strip-shaped elementary silver are plated on the smooth surface of the rough glass 3 at equal intervals, and the gap between every two elementary silver on the rough glass 3 is equal to the width of the elementary silver;
the striped plate 5 comprises a plate body 51, light absorption strips 52 and mirror surface strips 53 are alternately arranged on the plate body 51, the light absorption strips 52 and the mirror surface strips 53 are equal in width to simple substance silver, black paint is coated at the positions of the light absorption strips 52, the simple substance silver is also plated at the positions of the mirror surface strips 53, the simple substance silver has an excellent light reflection effect, and more light rays reflected to the ground glass 3 are ensured to enter a room after being reflected by the simple substance silver.
According to the invention, the photovoltaic power generation sheets irradiated by external light on the page plate 2 can generate current, and because the plurality of springs 6 are connected in parallel and then connected in series with the photoresistor 7 and the power supply pack, each photovoltaic power generation sheet can provide stable voltage when the outside has stable illumination, so that the springs 6 can be stably electrified by the power supply pack, and the electrified current is in inverse proportion to the resistance value of the photoresistor.
Because each page plate in the invention is arranged by inclining 45 degrees, when external light irradiates on the page plate 2, part of light is inevitably reflected to the ground glass 3 of the upper page plate, the side wall of the ground glass 3 close to the outdoor is provided with simple substance silver, the striped plate 5 is abutted against the ground glass 3 and is also provided with the simple substance silver, when the outdoor light is weaker, the photovoltaic power generation sheet cannot provide stable voltage to drive the spring 6 to shrink, at the moment, the light absorption strip 52 on the striped plate 5 is abutted against the simple substance silver on the ground glass 3, the mirror surface strip 53 and the simple substance silver on the ground glass 3 just cover the whole plane of the ground glass 3, and as the simple substance silver has excellent light reflection effect, more light irradiated on the ground glass 3 from the outside can be irradiated to the indoor so as to increase the indoor brightness.
When the external illumination is gradually enhanced, the voltage generated by the photovoltaic power generation sheet is gradually increased until the maximum voltage is reached and is not changed, the resistance value of the photosensitive resistor is still larger, the current passing through the spring 6 is also smaller, the spring 6 cannot be driven to contract, and the mirror surface strip 53 and the simple substance silver on the ground glass 3 still just cover the whole plane of the ground glass 3, so that the indoor brightness is ensured.
The external illumination is continuously enhanced, the power generation power of the photovoltaic power generation sheet is always at the maximum power, the resistance value of the photoresistor is reduced along with the increase of the illumination intensity, the current passing through the spring 6 connected with the photoresistor in series is increased, when the spring 6 passes through the current, each circle of metal on the spring 6 can generate a magnetic field to attract the metal, the magnetic field is stronger when the current is larger, the attraction between each circle of metal on the spring 6 is larger, namely the external illumination is stronger, and the spring 6 is shorter when the spring 6 contracts;
the spring 6 drives the striped plate 5 to move along with the striped plate 5 in the contraction process, the movement of the striped plate 5 can ensure that the light absorption strips 52 on the striped plate are not overlapped with the simple substance silver on the ground glass 3 any more to generate dislocation, and the mirror surface strips 53 are overlapped with the simple substance silver on the ground glass 3 to be propped against, so that part of light can irradiate on the light absorption strips 52 to be absorbed, and only the light irradiates on the mirror surface strips 53 and the simple substance silver on the ground glass 3 to be completely reflected indoors, so that the light reflected indoors is reduced; it is worth mentioning that in the process of enhancing the external illumination, the overlapping degree of the mirror surface strips 53 and the simple substance silver on the ground glass 3 is gradually increased, that is, the more light rays are irradiated onto the light absorbing strips 52 and absorbed, so that the light rays reflected to the indoor are in a relatively moderate state when the external illumination is enhanced, and the influence of the indoor over-brightness on the daily life is avoided.
