Expressway signboard capable of collecting rainwater for self-cleaning

Abstract

The invention relates to the technical field of expressway signboards, in particular to an expressway signboard capable of collecting rainwater for self-cleaning. The expressway signboard comprises asignboard body and a servo motor, one side of the signboard body is fixedly connected with a self-cleaning mechanism, and the self-cleaning mechanism comprises a support column; and a rainwater collecting bin is formed in one end of the interior of the supporting stand column, a first circulating bin is formed in one end of the supporting stand column, the interior of a water outlet spray head communicates with the interior of the water flowing bin, and a cleaning mechanism is fixedly connected to the other side of the signboard body. The expressway signboard can effectively collect rainwaterin rainy seasons, can achieve self-cleaning in dry and rain-free seasons, effectively solves the problem that water is difficult to take by pavement maintenance personnel, can quickly rub and clean dust remaining on the surfaces of signboard bodies, is matched with spray washing of the water outlet spray head, and enables the surface of the signboard body to be cleaner.

Description

technical field [0001] The invention relates to the technical field of highway signboards, in particular to a highway signboard capable of collecting rainwater for self-cleaning. Background technique [0002] Expressway, referred to as expressway, refers to a highway designed for high-speed driving. Expressways have different regulations in different countries, regions, times, and different scientific research fields. When driving on expressways, there are often Different signs are used to remind drivers to master the speed of driving and road traffic information, to warn drivers and to attract drivers' attention. Highway signage uses graphic symbols and text to convey specific information to manage traffic, indicate driving directions, and Facilities to ensure smooth roads and safe driving. [0003] After long-term use, the road signs are exposed to the external environment for a long time. The long-term wind and sun in the external environment will inevitably cause the su...

Problems solved by technology

[0004] The object of the present invention is to provide a highway signboard that can collect rainwater for self-cleaning, so as to solve the problem of long-term use in the above-mentioned background technology. Long-term exposure to the external environment, long-term wind and sun in the external environment will inevitably cause the surface of the signboard to be covered with dust. The problem that the drivers of vehicles traveling on the expressway cannot get the feedback of the road sign information in time
