FIELD EXPERIMENTS OF A CITY STREET FENCE WATER JET CLEANER

摘要

The city street fences, made of iron bars and pieces with different shapes, are very difficult to clean by man traditionally. This method usually has a hard physical intensity, a lower efficiency and a higher cost. A new type of a cleaning machine, a City Street Fence Water Jet Cleaner (CSFWJC) has been designed and manufactured, which consists of two main parts of water jetting and rotary brush rubbing and can be equipped on spraying cars easily. First, the lower pressure water jets to the city street fences and cleans down the dust on them. Then the rotary brushes rub off the dunghill adheres to the city street fences. And last, the lower pressure water sprays to and scours the city street fences again. Field experiments show that a CSFWJC has a feasible structure, reliable performance, simple structure and ideal effect. The cost of cleaning street fences using the city street fence water jet cleaner can decrease to about 18.5 percent of that by the artificial method.
