[0002] A sludge scraper is a kind of engineering machinery equipment, which is mainly used to clean up silt, sand, etc., and then use a water pump to flush and unload it. The collector ring is a common product in motor and electrical accessories. It is usually used in combination with a brush to form a slip ring and a rotor collector ring. The main function of the collector ring is to change the direction of the current and ensure continuous current transmission in the electrical circuit. The existing collector rings of sludge scrapers are usually exposed during use, which may cause safety hazards such as electric shock or short circuit due to the exposure of the live parts of the collector rings. Secondly, the overall structure is relatively complex. During daily maintenance and replacement, some accessories need to be adjusted, resulting in a long production stoppage time, affecting the amount of water processed. At the same time, some accessories are relatively old-fashioned and not easy to purchase and replace, which makes it impossible to maintain the collector ring normally, affecting production operations; Therefore, we propose a high-stability collector ring protection device to solve the above problems. Utility Model Content
