Description

Solar three-body leisure boat

technical field

The invention relates to a leisure boat on water, in particular to a three-body leisure boat with two lower hulls that can rotate around the shaft and powered by solar cells, and belongs to the technical field of ship engineering.

Background technique

As a high-performance ship, the trimaran is characterized by better seaworthiness at medium and high speeds than monohulls and catamarans, and has a wide deck for large-area cabins. In recent years, with the development of the economy, developed countries use yachts as a way of people's water entertainment and sports, and the demand for yachts is increasing. In developing countries, yachts are mostly used as operating items in tourist attractions such as inland rivers, lakes and coastal areas for people to consume. These yachts are mainly powered by batteries and driven by electric motors to drive propellers to drive small and simple fiberglass boats with low speed. .

The currently designed solar tour boat uses ether energy as energy, and the electric energy converted by the solar energy charges the accumulator on the boat, and the accumulator supplies power to the motor. The electric motor drives the propeller (usually a common propeller) to push the boat forward. The maximum speed can reach more than 6.5 kilometers per hour, and it can carry 4 adults or more. However, these boats are backward in type and have single functions. In addition, they cannot be used in wind and waves due to the limitation of their own safety performance, so they cannot meet people's increasing entertainment and leisure requirements.

Chinese utility model patent CN201432794 discloses a solar braking ship, which mainly includes a main body of the ship, an electric propeller and a storage battery. The electricity generated by the photovoltaic solar panel is used to charge the battery through the intelligent charging controller, and then the battery supplies power to the ship's DC propulsion, thereby driving the ship's steering system to drive the ship. Chinese utility model patent CN201941960 discloses a solar yacht, which mainly includes a hull and a solar panel arranged on the top of the hull. Ribs are embedded in the top of the hull, and the solar panel and the ribs are fixedly connected by bolts. The solar panel is connected with the battery pack through the solar intelligent charge and discharge controller. Although the aforementioned two relevant patents all utilize solar energy to provide energy for ships, they are monohulls.
