Detailed description of the invention
In FIG, a kind of autoamtic-opening device of awning, it comprises expansion drum 1 and a cylinder 6.
As shown in Figure 1, the shape of expansion drum 1 is cylindrical, is filled with working media 3 in expansion drum 1 inside, and what this working media 3 adopted in the present embodiment is a certain amount of water, and this water is light water or is pure water.
In FIG, be provided with heat absorbing coating 4 at the external surface of expansion drum 1, its heat absorbing coating 4 is conventional black heat absorbing coating.
In FIG, be provided with the cloche 2 of a vacuum in the outside of expansion drum 1, this cloche 2 plays windbreak function.
Be provided with a reflective mirror 5 at expansion drum 1 and the below of cloche 2, with reflected sunlight, strengthen being heated of expansion drum 1 bottom.
In FIG, expansion drum 1 is connected through a connecting pipe 8 with the inner chamber of cylinder 6, and the piston rod end of cylinder 6 is connected with sunshade framework 7.Wherein, cylinder 6 is single action cylinder.
Sunshade framework 1 plays and supports and the effect of telescopic folding, so select joint position appropriate on skeleton to be connected with the piston rod end of cylinder 6 according to the shape and structure difference of awning.
In use procedure, the water in expansion drum 1 is because its boiling point is by temperature and effects of air pressure, and the coolant-temperature gage in expansion drum 1 constantly rises and evaporates, and its air pressure is just more and more higher; Boiling point is gentle is pressed into direct ratio, and water also can not seethe with excitement more than 100 degrees Celsius, so the air pressure in expansion drum 1 significantly can promote along with the increase gradually of temperature, thus the thrust that the gas in the inner chamber of cylinder 6 produces can be multiplied, the piston rod of cylinder 6 distally stretches out under the air pressure effect of inner chamber, and skeleton and awning are all launched.
Meanwhile, the autoamtic-opening device of the awning given by the present embodiment, when not needing to use, in order to prevent the water in expansion drum 1 to be heated, can be provided with a light barrier 9 above expansion drum 1 with cloche 2.
It should be noted that, expansion drum 1 should be arranged on the lowest part of this device when mounted, to collect the cooled water of this device.Simultaneously, reclaim in order to the piston rod of cylinder 6 can be made, should be tilted when awning is arranged on metope certain angle, pushed back by the piston rod of cylinder 6 after cylinder inner cavity pressure reduces because of the Action of Gravity Field of awning, thus allow awning keep the state regained when not having sunlight.In addition, sunshade framework also can install clockwork spring, the piston rod of cylinder 6 retracts by clockwork spring after cylinder inner cavity pressure reduces.
Fig. 2 gives the structural representation of the second embodiment of the present utility model.In fig. 2, a kind of autoamtic-opening device of awning, comprises expansion drum 1 and a cylinder 6 equally.Cylinder 6 adopts single action cylinder equally.
As shown in Figure 2, the shape of expansion drum 1 is spherical, is filled with working media 3 in expansion drum 1 inside, and what this working media 3 adopted is the air that pressure is equal to external atmosphere pressure.Black or other dark colour heat absorbing coatings 4 is scribbled at the external surface of expansion drum 1.
In fig. 2, identical with embodiment one, be provided with the cloche 2 of a vacuum in the outside of expansion drum 1, be provided with a reflective mirror 5 at expansion drum 1 and the below of cloche 2, expansion drum 1 is connected through a connecting pipe 8 with the inner chamber of cylinder 6, and the piston rod end of cylinder 6 is connected with sunshade framework 7.
With embodiment one unlike, a unidirectional one way valve 10 entering air is set being connected with expansion drum 1 on communicating pipe 8 nearby, the communicating pipe 8 at rigging position least significant end place is provided with a water accumulating cup 12, this water accumulating cup is provided with manual drain valve 13.
In order to purify the air of suction line, the import department of one way valve 10 has been provided with the screen pack 11 of filtered air dust effect.
Expansion drum 1 temperature under the irradiation of sunshine of the present embodiment raises gradually, due to the reason that air heats expands, expansion drum 1 and the pressure in communicating pipe 8 also raise gradually, the gas pressure entering the inner chamber of cylinder 6 promotes piston rod and overcomes awning gravity or spring tension distally stretches out, and awning is launched.When intensity of illumination weakens, expansion drum 1 temperature declines, and air is by cold events and internal pressure also declines, and the piston rod of cylinder 6 is pushed back because of awning gravity or spring tension, awning thus automatic drawing back.
When night temperatures is extremely low, the expansion drum 1 of the present embodiment and the air pressure in communicating pipe 8 will lower than ambient pressures, now one way valve 10 automatically will be opened and suck air to maintain the balance of inner and outer air pressure, expansion drum 1 and the air capacity in communicating pipe 8 is increased, farthest to promote internal pressure with this.
Due to air-breathing and the temperature difference of one way valve 10, the expansion drum 1 of the present embodiment and communicating pipe 8 inside can produce some condensed waters and be gathered in water accumulating cup 12, open manual drain valve 13 at set intervals and discharge water, guarantee exclusion in pipeline.Meanwhile, the autoamtic-opening device of the awning given by the present embodiment is not when needing to use, and manual drain valve 13 can be opened, then expansion drum 1 is identical with external pressure with communicating pipe 8 air pressure inside, and the piston rod of cylinder 6 can not eject.
The utility model reasonable in design, with low cost, automatically open awning when illumination is enough strong, during unglazed photograph, automatically can remain on retracted state, easy to use, applied widely.
