Embodiment Construction

[0023] The following examples describe the present invention in more detail.

[0024] combine Figure 1 to Figure 4 , the main structure of the present invention mainly includes rudder 1, hull 2, hydrofoil 3, bracket 4, flexible folding enveloping mesh cloth 5, steering gear 6, telescopic rod 7, multi-stage hydraulic cylinder 8, hydraulic pump and power supply 9, method Lan 10, watertight bulkhead 11, fixed member 12, hydraulic cylinder support member 13, hydraulic cylinder mounting base 14. The hull consists of three sections. A multi-stage hydraulic cylinder 8 is installed on the middle bulkhead 11 of the ship. Under the action of the power supply and the hydraulic pump 9, the multi-stage hydraulic cylinder 8 expands and contracts, so that the entire length of the ship increases or decreases; And the fixed member 12 ensures the strength of the hull; the flexible folding enveloping mesh cloth 5 is set to ensure the resistance performance of the hull; the captain adjusts acco...

Abstract

The invention provides a wave energy craft with variable ship length. It includes a wave energy vehicle composed of a hull, a hydrofoil installed on the lower part of the hull through a bracket, and a rudder installed at the tail of the hull. The hull is composed of three parts: the first section, the middle section and the tail section, and the middle section is a telescopic section. The wave energy vehicle with variable captain of the present invention can control the captain of the ship under different waves and sea conditions. Compared with a fixed-length wave energy vehicle, an appropriate change in the captain can improve the wave energy utilization efficiency of the wave energy vehicle. In long waves and high sea conditions, increasing the length of the ship can increase the pitch and heave range of the ship, thereby improving the propulsion performance of the aircraft. In short-wave and low sea conditions, reducing the length of the ship makes the moment of inertia smaller, the range of motion of the hull becomes larger, and the wave energy is more effectively used for propulsion.

Description

technical field [0001] The invention relates to a wave energy craft, in particular to a wave energy craft with variable ship length. Background technique [0002] Exploring ocean data is of great value and significance to global climate prediction, marine fisheries, and environmental monitoring. The cost of collecting marine information with traditional monitoring ships equipped with detectors or sensors is high. With the development of artificial intelligence and automatic control technology, the construction and maintenance costs of using unmanned ships for marine scientific research can be greatly reduced. Due to the small displacement of the unmanned ship, it is impossible to load too much fuel, and the wave energy vehicle uses waves to provide thrust to solve this problem, and has achieved a certain degree of success. However, the problem of the low speed of existing wave energy vehicles under low sea conditions remains to be solved. [0003] A wave energy vehicle is...
