Bulbous bow assembly

Abstract

The invention provides a bulbous bow assembly in the technical field of ship equipment. The bulbous bow assembly comprises a bulbous bow main body, a slideway and a driving slippage device, wherein the bulbous bow main body is arranged below a ship body along the length direction of a ship; the slideway is arranged between the ship body and the bulbous bow main body, and comprises slide rails which are distributed along the length direction of the ship and slide blocks matched with the slide rails in a sliding mode; the slide blocks slide front and back in the slide rails along the length direction of the ship; the slide rails are fixedly connected with the bottom of the ship body, and are fixedly connected with the top of the bulbous bow main body; the driving slippage device is fixedly arranged in the ship body, and comprises a main pulley and a driving belt; the main pulley is a fixed pulley; the driving belt surrounds the main pulley; two ends of the driving belt are respectively fixedly connected with the front end and the rear end of the bulbous bow main body. The ship body provided by the invention is separated away from the bulbous bow main body; the position of the bulbous bow main body can be adjusted in real time; according to a wave making cancellation principle, the bulbous bow main body can be fully utilized for reducing the ship wave making resistance under multiple navigation speeds and multiple sea conditions, furthest reducing the navigation resistance of the ship body, reducing energy source loss, and further reducing the operation cost.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a bulbous bow assembly. Background technique [0002] The bulbous bow of the hull appeared around 1960, and now bulbous bows are installed on various hulls to reduce the wave-making resistance of the hull and save fuel. [0003] It is well known in the shipbuilding industry that the disturbance of the bow and stern wave system of the hull is the root cause of the peaks and valleys in the curve of the wave-making resistance coefficient versus the Froude number. Nearby, this is a choice of master scale. The use of a bulbous bow can make the troughs it rises offset the crests formed by the front of the hull. Generally, the joint optimization design of the bulbous bow is added in the initial shape design stage of the hull, but this optimization design is only carried out at a specific speed and captain. Due to the fixed connection between the original bulbous bow and the hu...
