Multifunctional unmanned-boat twin-hull boat structure

Abstract

A multifunctional unmanned-boat twin-hull boat structure comprises a boat body, a supporting frame, a box body, a clamp, a propeller, a supporting board, four connecting boards, bolts and nuts. The four connecting boards are adopted to be connected with the two boat bodies to form a twin-hull boat structure, the boat bodies and the supporting frame are welded and fixed into a whole, remaining components are connected through bolts, and then the multifunctional unmanned-boat twin-hull boat structure can be dismounted conveniently and is beneficial to transportation. A streamline form is adopted by the surfaces of the boat bodies, the body bodies are wide and flat, and the head portions, left sides and right sides of the boat bodies are slightly sharp. The inclined angle between two sides of the supporting frame is 90 degrees, the supporting frame is L-shaped, the supporting board is respectively connected with two sides, with an inclined degree of 90 degrees, of the supporting frame through bolts, and then two gestures of the boat bodies can be adjusted. When the multifunctional unmanned-boat twin-hull boat structure is at a shallow position, the wide and flat sides of the boat bodies are floated above the water surface, namely, the boat bodies stand on the water surface transversely, the draft depth can be reduced, and the multifunctional unmanned-boat twin-hull boat structure is not grounded at the shallow position. When the multifunctional unmanned-boat twin-hull boat structure is at a deep position, the slightly-sharp ends of the boat bodies are floated above the water surface, namely, the boat bodies stand on the water surface vertically, the draft depth can be increased, and the stability of the unmanned boat on the water surface is improved.

Description

technical field [0001] The invention relates to a ship, specifically, the hull can be disassembled and adjusted into two structures, which are respectively suitable for shallow water channels and deep water channels. Background technique [0002] At present, the projects and content of marine surveying and mapping are increasing, which puts forward higher and higher requirements for the research and development and application of surveying and mapping methods and technologies. In offshore bathymetric surveys, manual surveying and mapping is usually carried out by boat, line by line, and area by line. The survey is generally divided into two parts: one is the deep sea area far from the shore (water depth exceeds 15m); the other is the shallow sea area near the shore (water depth is 0-15m). [0003] When working in deep sea areas, large ships (with a draft above 3.5m) are usually used to set up measuring equipment for 24-hour continuous measurement. If the measuring equipment...

Problems solved by technology

In actual operation, there are the following problems: first, it is difficult to set up measuring equipment on small boats; second, small boats generally can only operate when the tide is high, and cannot achieve all-weather operations; third, the near-shore water environment is usually very complicated: shoals, hidden reefs etc. will bring great potential safety hazards to the surveying work; fourth, the working environment of field investigators on small boats is extremely difficult and their safety cannot be guaranteed.

[0005] The above shows that in marine surveying and mapping, it is necessary to use ships with different drafts and sizes according to different water depths, and the operation difficulty in shallow water areas is much greater than that in deep water areas. Cannot be put into a vehicle or ship at will for transportation
