Ultrasonic road surface cleaner

Abstract

The invention discloses an ultrasonic road surface cleaner, which comprises a cleaning truck and an ultrasonic road surface cleaning system mounted on the cleaning truck. The ultrasonic road surface cleaning system comprises an oscillation circuit, an amplifying circuit, a matching circuit, an ultrasonic transducer and a power source circuit, wherein the amplifying circuit is connected with the oscillation circuit, the matching circuit is connected with the amplifying circuit, the ultrasonic transducer is connected with the matching circuit, and the power source circuit supplies power to the oscillation circuit, the amplifying circuit, the matching circuit and the ultrasonic transducer. The amplifying circuit comprises a low-voltage driving circuit and a high-voltage driving circuit, and an output end of the high-voltage driving circuit is connected with the matching circuit. The matching circuit comprises a tuning circuit and an impedance converting circuit, and signals output by the high-voltage driving circuit are output to the ultrasonic transducer connected with the output end of the impedance converting circuit after being subjected to frequency regulation and impedance conversion. The ultrasonic road surface cleaner is simple in structure, reasonable in design, simple and convenient in operation and use, low in cost, energy-saving, environment-friendly, fine in cleaning effect and convenient to be used and popularized.

Description

technical field [0001] The invention relates to a road surface cleaner, in particular to an ultrasonic road surface cleaner with energy saving, environmental protection and good cleaning effect. Background technique [0002] Today's road cleaning vehicles spray high-pressure water to wash the road surface to achieve the purpose of cleaning the road dust, but the road surface often has dust and oil stains that are not easy to clean, so the cleaning vehicle is difficult to clean and wastes precious water resources; while cleaning hotels, The ground of schools, libraries, shopping malls and other public places usually relies on manpower to use mops. The workload of each cleaning is reduced, time-consuming, laborious, and waste water, which is not suitable for the requirements of the times for human living environment. [0003] When the ultrasonic wave acts on the liquid, the rupture of each bubble in the liquid will generate a shock wave with great energy, which is equivalent t...

Problems solved by technology

During this process, shock waves are generated at the moment when the bubbles close, causing a pressure of 1012-1013 Pa and local high temperature around the bubbles. The huge pressure generated by this ultrasonic cavitation can destroy insoluble dirt and make them decompose in the solution, steam The direct and repeated impact of cavitation on the dirt, on the one hand, destroys the adsorption between the dirt and the surface of the cleaning parts, and on the other hand, it can cause the fatigue damage of the dirt layer and be removed. Ultrasonic cleaning has been applied to the cleaning of small items and workpieces. flushing, etc., but has not been applied to the field of road cleaning
