The core advantage of this remote-controlled dredger lies in its compact size and remote control operation, which can enter narrow underwater spaces that conventional dredgers cannot reach. It uses a 48V 100Ah lithium battery, supporting 4 hours of continuous operation, and the charging time is only 3 hours. The whole machine uses 304 stainless steel and engineering plastic materials, with a protection grade of IP68, which can adapt to various underwater environments. The remote control system adopts a 2.4G wireless signal, with a control distance of up to 500 meters, and can realize real-time monitoring of the underwater operating status, improving the safety and accuracy of operation. In addition, the dredger is equipped with a detachable slurry pump, which is easy to maintain and replace.
The dredger has an overall length of 2.1 meters, molded beam of 0.8 meters, and total weight of 120 kilograms. The maximum underwater working depth is 10 meters, and the dredging depth is 3 meters. It is equipped with a brushless DC motor with rated power of 2.2kW, and the discharge pipe has an inner diameter of 80 mm. The battery is a 48V 100Ah lithium iron phosphate battery, supporting 4 hours of continuous operation under full load. The remote control distance is 500 meters, and the protection grade of the whole machine is IP68, which can resist water immersion and corrosion. The slurry pump uses wear-resistant ceramic materials, with a service life of more than 500 hours.
This remote-controlled mini underwater dredger is mainly applicable to underwater pipeline maintenance, wharf pile foundation cleaning, underwater platform sediment removal, underwater bridge pier cleaning and other narrow underwater space scenarios. It can safely and efficiently remove sediment and foreign matter in narrow underwater spaces, avoiding the risk of divers entering deep water. It is also suitable for dredging projects in small ports, aquaculture ponds and other small water areas where large dredgers cannot operate.
