The Keelcrab

描述

The Keelcrab是Keelcrab的Cleaning-Robots。 面向清洁、检查设计。 关键数据：10 kg。

The Keelcrab is Aeffe's mid-range underwater drone for cleaning and inspecting the hulls of yachts, pleasure boats and houseboats, designed and built in Italy. Its neutrally buoyant plastic shell is held against the hull by the suction of a powerful marinised pump motor that also sucks up the algae it removes, and tracked rubber or PVA brushes move it in any direction and over obstacles. Cushioned counter-rotating disc brushes on a dedicated waterproof motor adapt to the surface by up to 15 mm, and the Keelcrab Bag filter with a nylon bag collects the removed growth so it cannot settle back on the hull in still water. An HD camera and two 400-lumen LEDs stream video to a wired remote with joystick and 7-inch display. It cleans about 6 square metres a minute, weighs about 10 kg, draws 350 W through an external power box and uses a 20 m Kevlar-reinforced cable; an optional diver pack adds handles and a switch for manual use while diving. Its A.N.C.C.P.-certified brushes are designed to remove the first 3-5 mm of growth without stripping antifouling paint, which the maker says extends the paint's life, slows barnacle formation, cuts fuel consumption and keeps sailing performance up.
