Description

Aerodynamic propeller ship model

technical field

The utility model relates to the field of children's toys, in particular to an aerodynamic propeller ship model.

Background technique

Existing ship model is generally driven by the propeller that is arranged on the hull stern. When the ship model is in motion, the propeller is below the water surface. The propeller rotates under the drive of the motor, thereby pushing the ship model to travel on the water surface.

However, since the ship model itself has certain gravity, and the propeller must be positioned under the water surface, the ship model cannot be used in environments such as shallower waters, ice or swamps. For example, in relatively shallow waters, when the propeller is rotating, it may contact the bottom of the shallow water, which will affect the operation of the propeller. And when on the ice, this kind of ship model cannot be started. Therefore, the range of use of existing ship models is limited.

During the sailing process of the propeller ship model, the air can provide an upward supporting force for the ship wing 8, so that the propeller ship model faces the water surface or faces side by side. The reduced pressure can reduce the draft of the propeller ship model, thereby reducing the probability of the propeller ship model being in contact with the bottom when navigating in shallow water; the second is to reduce the friction between the lower bottom plate 5 and the water surface or ice surface, Under the condition that the power unit 3 provides the same power, the propeller ship mold has a higher speed.

In the above seven embodiments, the power device 3 is an electric motor. The power of the motor is selected according to the size of the hull 1. The big propeller ship model of the hull 1 has a larger weight, and the propulsion force driving it forward is also larger, so the power of the motor is also larger. And the smaller propeller ship model weight of hull 1 is less, so the power of electric motor is also less. And the power of the motor also determines the maximum speed when the propeller ship model sails. The higher the speed of sailing, the greater the power of the electric motor required. Users can choose according to their actual needs.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model.
