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 variable ship length type wave energy underwater vehicle. The variable ship length type wave energy underwater vehicle comprises a wave energy underwater vehicle body, whereinthe wave energy underwater vehicle body comprises a ship body, a hydrofoil which is mounted at the lower part of the ship body through a support, and a rudder which is mounted at the tail part of theship body; the ship body comprises three parts, namely, a head section, an intermediate section and a tail section; and the intermediate section is a telescoping section. According to the variable ship length type wave energy underwater vehicle, the length of a ship in the sea with different wave conditions can be controlled; compared with a fixed ship length type wave energy underwater vehicle,the variable ship length type wave energy underwater vehicle has the advantages that the ship length can be properly changed so as to improve the wave energy utilization efficiency of the wave energyunderwater vehicle; in case of a long wave height condition, the ship length can be increased in order to increase the longitudinal swinging and heaving range of the ship, and as a result, the propelling performance of the underwater vehicle can be improved; in case of a short wave height condition, the ship length can be decreased to reduce the rotating inertia, thus the ship body moving range isexpanded, and as a result, the wave energy can be effectively utilized to propel.

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...
