Abstract

The utility model discloses a traffic appliance. By the photocatalyst attached to a vehicle main body, the utility model has the use function of the general curtain wall plate and a self-cleaning function. The traffic appliance can be easily cleaned by the flushing of clean water or rain wash. The traffic appliance can keep cleanness and shapely figure for a long time, save cleaning expenses and avoid danger.

Description

A kind of traffic appliance

Technical field

The utility model relates to a kind of traffic appliance, especially a kind of traffic appliance with self-cleaning function.

Background technology

The shortcoming of existing traffic appliance is: traffic appliance is used in the middle of atmospheric pollution very serious the road limit even road, surface at traffic appliance is adsorbed a large amount of dust and airborne other pollutents easily, feasible surface is very dirty, the image in city also is affected, and owing to be in the passing busy environment of traffic, cleaning cost is very high, and danger is also very big.

The utility model content

The purpose of this utility model is to provide a kind of traffic appliance, the result of use that had both had existing traffic appliance, can prevent to adsorb dust and airborne other pollutents again, can keep the cleaning of traffic appliance outward appearance attractive in appearance for a long time, save the time and the expense of cleaning traffic appliance, avoid causing danger.

A kind of traffic appliance described in the utility model comprises the traffic appliance main body, is attached with photocatalyst on body surfaces.

But especially adhere to photocatalyst in the illumination surface of traffic appliance.

Photocatalyst is that a class is representative with the Nano titanium dioxide, has the general name of the photosemiconductor material of photo-catalysis function, and titanium dioxide can show two kinds of features through radiation of visible light: extremely strong water-absorbent and higher oxidation potential.Therefore if having dust or greasy dirt to drop on the traffic appliance, it is actually and swims on this layer of surface of shell thin water film, use scour without sediment motion, even rain drop erosion just can be washed it off at an easy rate.After testing, photocatalyst is harmless.

The coating of photocatalyst on the surface of a kind of traffic appliance described in the utility model.The traffic appliance surface that coating is coated in, in the result of use that does not influence existing traffic appliance, can prevent to adsorb dust and airborne other pollutents again, can keep the cleaning of traffic appliance outward appearance attractive in appearance for a long time, thereby saved the spending of employing artificial cleaning, avoided causing danger.

Embodiment

A kind of traffic appliance described in the utility model comprises traffic appliance main body 1, is attached with photocatalyst 2 on the surface of main body 1.

Embodiment 1

Described traffic appliance is a traffic lights, and lampshade and pole that described main body 1 is a traffic lights on the surface of lampshade and pole, are attached with photocatalyst 2 (as Fig. 1).

Embodiment 2

Described traffic appliance is the freeway traffic guardrail, and described main body is anti-striking plate, column and the web member (as Fig. 2) of freeway traffic guardrail, and the surface at anti-striking plate, column and web member is attached with photocatalyst 2.Perhaps described traffic appliance is the freeway traffic guardrail, and described main body is the shield posts of freeway traffic guardrail, on the column surface, is attached with photocatalyst 2 (as Fig. 3).

Embodiment 3

Described traffic appliance is a traffic indication board, and board body and pole that described main body 1 is a traffic indication board on the surface of direction board board body and pole, are attached with photocatalyst 2 (as Fig. 4, Fig. 5).

Embodiment 4

Described traffic appliance is the Urban traffic guardrail, and described main body is to block bar and base, on the surface of blocking bar and base, is attached with photocatalyst 2 (as Fig. 6,7).

The traffic appliance that contains the photocatalyst dirt settling utilizes sunlight or light exciting light catalyst, produces to reduce dust and the adherent effect of other air pollutant.Nano titanium dioxide can show extremely strong water-absorbent through radiation of visible light.Therefore if there is the dust greasy dirt to drop on the traffic appliance, it is actually on this layer thin water film that swims in traffic appliance, uses scour without sediment motion, or only depends on rain drop erosion just can remove dust and pollutent like a cork.

The utility model can be applied to the traffic appliance that various occasions are used.
