The specific embodiment
Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this manual.
See also Fig. 1 to Fig. 4.Notice, the appended graphic structure that illustrates of this manual, ratio, size etc., equal contents in order to cooperate manual to disclose only, understand and reading for person skilled in the art scholar, be not in order to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not influencing under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this manual as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under no essence change technology contents, when also being considered as the enforceable category of the utility model.
Shown in Fig. 1,2,3,4, the utility model provides a kind of multi-functional shutter, and it comprises a plurality of louvre blades 1 that are suspended on the window frame 2, and a plurality of louvre blades 1 are arranged in parallel.Each louvre blade 1 includes a movable part 11 and a fixed part 12, and movable part 11 is hinged by jointed shaft with fixed part 12.Movable part 11 is connected with driving mechanism, can realize the opening and closing of shutter by driving mechanism.As a kind of usual way, driving mechanism can adopt spool 3 to add the mode of angular adjustment rope, the movable part 11 of each louvre blade 1 all is connected with the angular adjustment rope, just can realize the opening and closing of shutter by spinning reel 3, when shutter is closed, the upper end of louvre blade movable part 11 cooperates to realize closing of shutter with fixed part 12 ends of this louvre blade top louvre blade, and movable part 11 is adjusted the angle maximums can reach 120 °.
Fixed part 12 at each louvre blade 1 is equipped with photovoltaic module 7, and the back side of photovoltaic module 7 is provided with electrothermal module 8 (as shown in Figure 4), photovoltaic module 7 and electrothermal module 8 welding.Louvre blade 1 is polythene material, and movable part 11 adopts parabola shaped, and reflector layer is all given birth on the two sides of movable part 11, and reflector layer can adopt platinum plating layer or silver coating, and when shutter was in closed condition, the sensitive surface of photovoltaic module 7 was relative with the reflector layer of movable part 11.
As shown in Figure 1, when shutter was closed, 11 reflections accumulated on the photovoltaic module 7 sunshine through movable part, are electric energy by photovoltaic module 7 with transform light energy.Work along with photovoltaic module 7, its temperature constantly raises, temperature can be up to 80 degree, and ambient temperature only has degree more than 20, this moment electrothermal module 8 with photovoltaic module as the hot junction, environment temperature is as cold junction, and the used heat that under the driving of the thermo-electromotive force of degree more than 50 photovoltaic module 7 is produced converts electric energy to and converts electric energy to.The electric energy of the two generation stores in battery 6 by lead 4, power controller 5.The electric energy that produces also can directly be connected with electrical network by inverter, realizes generating electricity by way of merging two or more grid systems, and perhaps directly is connected with DC equipment, drives DC equipment work.
