Embodiment 1

[0035] A flexible catamaran unmanned boat with adjustable attitude, its structure is as follows: Figure 1-Figure 7 As shown, it includes a power propulsion device 4, and two sides of the power propulsion device 4 are provided with symmetrical double-air-cushion cylindrical support devices 1; the power propulsion device 4 is provided with a control device 3 connected by a spring damping device 2, The power propulsion device 4 is also provided with a pair of telescopic devices 5 connected with the double-air-cushion cylindrical support device 1 .

[0036] The spring damping device 2 includes a high-strength spring 203, and the two ends of the high-strength spring 203 are provided with a long connecting rod 202, and any long connecting rod 202 is provided with a short connecting rod 205 away from the end of the high-strength spring 203, and the short connecting rod 205 One end away from the long connecting rod 202 is provided with a shock-absorbing ball joint 201; the high-stren...

Embodiment 2

[0040] A flexible catamaran unmanned boat with adjustable attitude, the difference from Embodiment 1 is that the front end of the deck 406 is not provided with a deflector 405 .

[0041] When in use, when the unmanned boat needs to adjust its posture or slow down, the control device 3 issues an instruction, and the electric push rods on both sides of the power propulsion device 4 begin to retract, and the movable end of the electric push rod drives the movable ball joint to retract, and the movable ball joint Drive the universal shaft seat 103 on one side to rotate, so that the tail end of the air bag 101 moves closer to the power propulsion device 4, so that the universal shaft seat 103 on the other side also rotates together, and the attitude of the unmanned boat after rotation is as follows: figure 2 shown. At this time, due to the increase of the force bearing area along the forward direction, the unmanned boat is impelled to decelerate rapidly under the action of the pro...

Abstract

The invention belongs to the technical field of unmanned boats, and particularly discloses a posture-adjustable flexible double-body unmanned boat. The posture-adjustable flexible double-body unmannedboat comprises a power propelling device, wherein the two sides of the power propelling device are provided with symmetrical double-air-cushion type cylindrical supporting body devices; a spring damping device connected with a control device is arranged on the power propelling device, and a pair of telescopic devices connected with the double-air-cushion type cylindrical supporting body device isarranged on the power propelling device; and the two sides of the power propelling device are provided with the symmetrical double-air-cushion type cylindrical supporting body devices, so that the sailing stability of the unmanned boat is ensured; the power propelling device and the double-air-cushion type cylindrical supporting body devices are connected through a flexible structure, the stability of the unmanned boat is improved, the tail of a deck is connected with the telescopic devices, the navigation speed and the posture can be adjusted at any time, the adjustability of the unmanned boat is more flexible, the design of the spring damping device plays a good role in buffering and damping a control platform, and the abrasion between the precise parts on the control platform is reduced.

Description

technical field [0001] The invention belongs to the technical field of unmanned boats, in particular to a flexible double-hull unmanned boat with adjustable attitude. Background technique [0002] With the development of key technologies of unmanned boats, many types of unmanned boats with good performance, shallow draft and long endurance have been developed at home and abroad, and they follow ships to go to sea to perform tasks. However, due to its own weight and the influence of the harsh environment at sea, the unmanned boat has a single navigation attitude, poor adjustment ability, severe wear and tear on key components, and high maintenance costs, which cannot meet the multi-tasking requirements in complex fields and harsh environments. Therefore, in the face of the complex marine environment, how to adjust the speed and navigation attitude of the unmanned boat and improve the service life of the unmanned boat is the key factor for the development of the unmanned boat....
