Problems solved by technology

[0002] As an unmanned surface robot, unmanned ships are widely used in various water operations to perform corresponding high-risk and cumbersome tasks and reduce work risks and difficulties. However, most of the existing unmanned ships are small and medium-sized ships. Perfect shock and anti-rolling system, the shock and anti-rolling is mainly realized by the bilge keel, which can reduce the rolling by about 40%, but the damping characteristics of small and medium-sized ships to the rolling are poor, resulting in the existing unmanned ships. The stability is not high, and the water surface operation is greatly affected by the environment

specific Embodiment approach

[0033] Such as figure 1 Shown is a three-dimensional view of the shock-absorbing unmanned ship, which is composed of a shock-absorbing base 5, a cat-like link-type leg shock-absorbing structure 4, and a self-stabilizing cabin structure.

[0034] Such as figure 2 Shown is the structural diagram of the first-level shock-absorbing self-stabilizing system. The hinge connection point 11 on the upper part of the arch bridge is the connection point connecting the second-level shock-absorbing and self-stabilizing system. The external force borne will be transmitted from both ends to the alloy arch bridge A51 and the alloy arch bridge B54. When the unmanned captain buoy 6 is subjected to an upward impact force, the alloy arch bridge A51 and the alloy arch bridge B54 are first deformed by the impact force to slow down the huge impact force brought by the bottom of the unmanned ship. Metal rubber shock absorbers 52 are added to the alloy arch bridge A51 and the alloy arch bridge B54 t...

Abstract

The invention discloses an unmanned ship with a three-stage damping self-stabilizing system. The unmanned ship with the three-stage damping self-stabilizing system comprises double long buoys, dampingbases, cat-like connecting rod type leg damping structures, a six-degree-of-freedom hydraulic self-stabilizing device and a ship cabin, wherein the double long buoys are provided with the four damping bases, the bottom end of each cat-like connecting rod type leg damping structure is connected with the corresponding damping base, and the top end of each cat-like connecting rod type leg damping structure is connected with a connecting bridge; and the six-degree-of-freedom hydraulic self-stabilizing device is arranged on the connecting bridge, and the ship cabin is mounted on the six-degree-of-freedom hydraulic self-stabilizing device. The invention provides an unmanned ship design scheme with a three-stage damping system on the basis of the current situation of application and research ofthe unmanned ship. Through the design of a base damping structure, high-speed navigation under low-amplitude surge is realized; and through the design of the cat-like connecting rod type leg damping mechanisms, stable navigation under high-amplitude surge is realized. According to the unmanned ship with the three-stage damping self-stabilizing system, a bionic structure design is added, and the cat-like connecting rod type leg structures are used as four supports of the unmanned ship, so that the stability and the damping effect of a ship body are improved.

Description

technical field [0001] The invention relates to the field of unmanned ships, in particular to an unmanned ship with a three-stage shock-absorbing self-stabilizing system. Background technique [0002] As an unmanned surface robot, unmanned ships are widely used in various types of water operations to perform corresponding high-risk and cumbersome tasks and reduce work risks and difficulties. However, most of the existing unmanned ships are small and medium-sized ships. Perfect shock and anti-rolling system, the shock and anti-rolling mainly depends on the bilge keel, the bilge keel can reduce the roll by about 40%, but the damping characteristics of small and medium-sized ships to the roll are poor, resulting in the existing unmanned ships. The stability is not high, and the water surface operation is greatly affected by the environment. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention is to design a...
