Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the traffic lights with dedusting function proposed by the present invention;
Fig. 2 is the structural schematic diagram of embodiment 2.
In figure: 1 friction plate, 2 hole for water sprayings, 3 extension airbags, 4 memory metal sheets, 5 elastic-friction pieces, 6 device chambers, 7 tuning forks, 8 tapered openings, 9 connecting rods, 10 ball valves, 11 overarms.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1, a kind of traffic lights with dedusting function, including the overarm 11 for installing traffic lights, overarm 11 upper end is equipped with water storage tank, and water storage tank is connected to conduit is passed through with the water supply line for being embedded in below ground, hang oneself from a beam 11 side Device chamber 6 is equipped in wall, the inner top of device chamber 6 is fixedly connected with tuning fork 7, and two opposite sides of yoke of tuning fork 7 are all provided with Flexible friction plate 5, elastic-friction piece 5 use heat conduction copper sheet, are equipped in device chamber 6 and contact always with two elastic-friction pieces 5 The friction plate 1 of sliding, friction plate 1 are fixedly connected on the inner wall of device chamber 6 by connecting rod 9, are set on the lower end surface of friction plate 1 There is a rectangle sliding slot, be equipped with memory metal sheet 4 in rectangle sliding slot, when 4 room temperature of memory metal sheet in the form of sheets, and is more than metamorphosis in temperature Twisted shape is twisted into when temperature, memory metal sheet 4 is adopted Ni-Ti memorial alloy and is made, and transformation temperature is 40 DEG C, with the side of overarm 11 Wall is equipped with hole for water spraying 2, and hole for water spraying 2 is located at the downside of device chamber 6, and ball valve 10 is equipped in hole for water spraying 2, the valve rod of ball valve 10 It extends in device chamber 6 and is fixedly connected with the lower end of memory metal sheet 4,11 side wall of hanging oneself from a beam is equipped with and 6 connected surface of device chamber The tapered opening 8 that the arc and face tuning fork 7 of middle part protrusion are arranged in the vertical direction.
In the present invention, when red light lights, the vehicle of dealing is parked in the two sides of traffic lights, at this time numerous automobile engines Vibration is resonated with the tuning fork 7 in device chamber 6, and the vibration of numerous automobile engines keeps the vibration amplitude of tuning fork bigger, vibration Time is longer, therefore elastic-friction piece 5 and the heat of the friction generation of friction plate 1 are more, when memory metal sheet 4 reaches transformation temperature When, memory metal sheet 4 is twisted into twisted shape, and then rotates with ovable valve stem, and ball valve 10 is opened, under the hydraulic pressure in water storage tank, storage Water in sink is sprayed from hole for water spraying 2, is carried out water spray to pavement two sides and is moistened, and influence of the dust to pedestrian is reduced.
Embodiment 2
Referring to Fig. 2, the left and right sides of friction plate 1 is arc, and the curvature of 1 upside of friction plate is greater than the curvature of volume two, The inner wall of 6 left and right sides of device chamber is equipped with sliding slot 12, and the two sides of friction plate 1 are fixedly connected to connecting rod 9, and connecting rod 9 is remote One end from friction plate 1 is located in sliding slot 12, and connecting rod 9 is connected to the interior bottom of sliding slot 12, extension airbag by extension airbag 3 It is equipped with low boiling point in 3 and evaporates liquid, low boiling point evaporates liquid and uses acetaldehyde, and at 20.1 DEG C, the lower end surface of friction plate 1 is equipped with boiling point Rectangle sliding slot is equipped in rectangle sliding slot matching and only can be along the slide bar that it is slided up and down, the lower end of slide bar and memory metal The upper end of piece 4 is fixedly connected.
In the present embodiment, summer temperature on average is higher, and the low boiling point evaporation liquid in extension airbag 3 evaporates more, extension airbag 3 Connecting rod 9 will be pushed to move up, and then contact elastic-friction piece 5 with the arc surface part of friction plate 1, heat production when reducing friction, And then effectively prevent in summer when there is automobile to pass through, the heat of elastic-friction piece 5 and the friction generation of friction plate 1 reaches memory The abnormal temperature of sheet metal 4.
In spring and autumn, temperature on average is slightly lower with respect to summer, and the liquid of low boiling point evaporation at this time evaporates less, extension airbag 3 The distance for pushing connecting rod 9 to move up is less than the distance moved up summer, and elastic-friction piece 5 and friction plate 1 completely attach at this time, improves The heat that elastic-friction piece 5 is generated with the friction of friction plate 1 in vibration of tuning fork 7, working as it in spring and autumn has numerous vehicles When being parked in the two sides of traffic lights, the heat that the vibration of tuning fork 7 generates elastic-friction piece 5 and friction plate 1 sufficiently achieves memory gold Belong to the transformation temperature of piece 4.
In winter, ambient temperature is lower, and the low boiling point evaporation liquid evaporation in extension airbag 3 can be ignored, at this point, bullet Property friction plate 5 do not contacted with friction plate 1, and then tuning fork 7 will not occur shake to make the friction of elastic-friction piece 5 Yu friction plate 1, subtract The abrasion of few elastic-friction piece 5, while can also prevent winter from sprinkling water in pavement two sides causes automobile to be difficult to braking of braking, and reduces Traffic accident.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
