Background technique

At present, the proportion of ships using sails on existing ships is very small, especially the sails on pleasure boats, which are more ornamental than practical. Sail types are divided into hard sails and soft sails, hard sails have airfoil hard sails, rotary drum sails, soft sails have canopy soft sails, airfoil soft sails and sky sails. The above sails more or less provide auxiliary thrust for the advancement of the vessel due to the action of the air during the advancement of the vessel. However, for most ocean sightseeing cruise ships, their daily working hours are limited, and they are not basically working 24 hours a day like cargo ships. Therefore, the cost recovery period of using sails is long, and the sails are left idle when the cruise ship stops working, and the wind energy on the ocean cannot be effectively utilized, and the energy consumption of ships is reduced to a limited extent.

Utility model content

In order to improve the utilization rate of wind energy of pleasure boats and solve the problem of less working time and less energy consumption of sails on existing pleasure boats, the utility model provides an auxiliary thrust that can provide auxiliary thrust for ships during the traveling process of the ships, and can be converted into Vertical axis wind turbine, a new type of energy-saving sail for ocean cruise ships that provides power for daily life on board.

The technical scheme that the utility model solves its technical problem adopts is:

Provided is an energy-saving sail for an ocean cruise ship, which includes a plurality of rotary sails, which are arranged on the upper deck or roof deck of the cruise ship. Each rotary sail includes a central axis of rotation, a telescopic device and a plurality of airfoil blades, and the telescopic device is sleeved On the central axis of rotation, a plurality of telescopic rods are evenly distributed on the telescopic device, and an airfoil blade is fixed on the top of each telescopic rod;

The energy-saving sail also includes a motor, an energy converter and an energy storage battery, the rotating central shaft is connected with the motor and the energy converter, and the energy converter is connected with the energy storage battery.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The energy-saving sail for ocean cruise ships according to the embodiment of the utility model includes a plurality of drum sails, which are arranged on the upper deck or roof deck of the cruise ship, and each drum sail includes a rotating central shaft 4, a telescopic device and a plurality of airfoil blades 1 , the telescopic device is sheathed on the central axis of rotation through a central hole, a plurality of telescopic rods 2 are evenly distributed on the telescopic device, and an airfoil blade 1 is fixed on the top of each telescopic rod.

The energy-saving sail also includes a motor, an energy converter and an energy storage battery, the rotating central shaft is connected to the motor, and the energy converter is connected to the energy storage battery.

In one embodiment of the utility model, according to the size of the pleasure boat, an appropriate number and a suitable size of rotating drum sails are arranged on the upper deck or the roof deck of the pleasure boat. The drum sail is composed of a plurality of airfoil blades, and the airfoil blades 1 are connected to the central axis of rotation 4 through telescopic rods 2 . When the ship is running, the airfoil blades 1 are folded and closed to form a cylindrical drum sail, as shown in Fig. 1 and Fig. 2 .

During the running stage of the ship, the telescopic rod 2 is in a retracted state, so that the airfoil blade 1 forms a cylindrical rotary sail. The rotating central shaft 4 is driven by a small motor to rotate at a low speed, and the rotating drum sail rotates at a low speed driven by the rotating central shaft 4 . The airfoil blade 1 thus also rotates with the same angular velocity. Under the action of the wind, the air with speed and the rotating drum sail produce the Magnus effect, and the wind acts on the surface of the rotating drum sail to form thrust and provide auxiliary thrust.

The energy-saving sail for marine pleasure boats of the utility model also includes a cover 3, which is arranged on the top of the airfoil blade 1, and is used to improve the propulsion efficiency of the rotary sail.

When the ship stops running, the motor is turned off, and the rotating drum sail stops rotating. The telescopic rod 2 in the telescopic device can be stretched out through the hydraulic system, and the airfoil blade 1 is unfolded as shown in FIG. 3 . The cover 3 rises to avoid hindering the rotation of the airfoil blade 1 . The rotating drum sail becomes a vertical axis wind generator as shown in Figure 4. Under the action of wind force, the wind drives the airfoil blade 1 to rotate, and the rotation of the airfoil blade 1 drives the rotation of the central axis 4, so that the kinetic energy is converted into Electric energy forms a generator, and the generated electricity is stored in batteries for use by the crew or passengers on board the ship.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present utility model.
