Low-resistance mast of high-speed planing boat

Abstract

The invention discloses a low-resistance mast of a high-speed planing boat. The low-resistance mast of the high-speed planing boat comprises a mast body arranged on the high-speed planing boat, wherein the bottom of the mast body penetrates through a compass deck and is fixedly connected with the top of a cab arranged on the lower part of the compass deck through bolts; the mast body is of a hollow structure; the mast body is made of carbon fiber composite materials; the mast body is thickened from the top of the mast body to the bottom of the mast body in sequence; the mast body comprises a windward side and a leeward side; an included angle between the windward side and the top of the cab is 120-150 degrees; the top of the leeward side is connected with the compass deck through a sling and a hanging ring; and two reinforcing plates are arranged between the leeward side and the compass deck. The mast body made of the carbon fiber composite materials can improve the working stability of a precision electronic instrument in a complex magnetic field environment, and the weight of the mast body can be reduced. Through the mould line design of the mast body, the wind load capacity of the mast body is increased.

Description

technical field [0001] The invention relates to a mast, in particular to a low-drag mast of a high-speed planing boat. Background technique [0002] At present, in the design of modern ships, the mast is a part that needs to be considered in the design. The mast needs to undertake multiple functions such as ship communication, lighting, detection, and forecasting. The traditional ship mast structure is a truss structure. This structure has a small wind load and strong wind resistance. When the ship is running at high speed, it suffers from small wind pressure resistance. The structural defects of the truss mast itself lead to radar on the mast. Such precision electronic instruments may interfere with each other, and the mast is easy to vibrate. Any small vibration may cause the precision electronic instruments on the mast to malfunction, shorten the life, and even lead to direct damage to the equipment. The cylindrical mast can effectively avoid these problems, but the wind ...

Problems solved by technology

The traditional ship mast structure is a truss structure. This structure has a small wind load and strong wind resistance. When the ship is running at high speed, it suffers from small wind pressure resistance. The structural defects of the truss mast itself lead to radar on the mast. Such precision electronic instruments may interfere with each other, and the mast is easy to vibrate. Any small vibration may cause the precision electronic instruments on the mast to malfunction, shorten the life, and even lead to direct damage to the equipment. The cylindrical mast can effectively avoid these problems, but the wind The load will pose a threat to the cylindrical mast, so the present invention will reduce the wind pressure resistance formed by the wind load of the traditional cylindrical mast to achieve the best performance
