A hydrofoil water rescue device

Abstract

The invention provides a hydrofoil-type water rescue device. The hydrofoil-type water rescue device comprises a hydrofoil structure installed at a lower part of a cabin. The hydrofoil structure comprises left and right hydrofoils which can control a rotation angle independently, and further comprises a distance detecting unit installed at a rear part of the cabin which is used for detecting a distance between the cabin and a water surface. While the hydrofoil-type water rescue device is forwards moved, the cabin departs from the water surface, a frictional resistance is reduced, and the hydrofoil-type water rescue device is not provided with a traditional rudder structure. Through changing the rotation angle of the left and right hydrofoils, the control of a height of the cabin away from the water surface, a forward direction, and a turning radius is realized, and energy consumption is reduced, thereby water cruising power of the rescue device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of water rescue equipment control, and in particular relates to a hydrofoil type water rescue equipment. Background technique [0002] Traditional water rescue boats such as figure 1 As shown, it includes a cabin body 1-1 floating on the water surface and an underwater propeller (such as a propeller), and for unmanned rescue equipment on water, endurance is a very important technical parameter, and energy consumption is a decisive factor. key factor in endurance. The traditional hull structure will form greater resistance when sailing at high speed, resulting in greater energy consumption. [0003] At the same time, the traditional water rescue boat adjusts the course by adding the turning rudder to the nozzle of the propeller. By adjusting the angle of the rudder, the water velocity on both sides of the rudder is affected to achieve the turning effect. The collision and friction between the water flow an...

The traditional hull structure will form greater resistance when sailing at high speed, resulting in greater energy consumption

[0003] At the same time, the traditional water rescue boat adjusts the course by adding the turning rudder to the nozzle of the propeller. By adjusting the angle of the rudder, the water velocity on both sides of the rudder is affected to achieve the turning effect. The water flow collides and rubs against the rudder, which wastes part of the energy
