Description

Keel battery system for unmanned sailing boat

Technical Field

The utility model relates to the technical field of sailing boats, in particular to a keel battery system for an unmanned sailing boat.

Background

Sailing vessels, i.e. vessels that are propelled by wind, are known and comprise mainly hull, sail etc. structures. Keel sailboats refer to all sailboats that include a keel component. The keels of modern sailing boats are arranged at the bottom of the boat and have different shapes, and are connected with the boat body through the keel brackets, so that the keels are important structures for adjusting the center of gravity of the boat body, increasing the righting moment and improving the stability of the boat body.

The keels of the existing keel sailing boat and the keel unmanned sailing boat are cast iron or other metal materials, and only play a role in reducing the center of gravity of the boat body and increasing the righting moment. The existing power battery for the unmanned sailing boat and the power battery for the electric unmanned keel sailing boat are arranged in the boat body and provide electric power for the electric propulsion device. Because the battery generates heat when charged and discharged, an additional heat sink is required. The passive heat dissipation system increases the weight of the hull and the active heat dissipation system increases the energy consumption. Once the power battery arranged in the ship body is in thermal runaway, the high temperature is easy to ignite the glass fiber ship body, so that the ship is burnt.
