Small-sized tugboat

Abstract

A small-sized tugboat belongs to the technical field of tugboats and comprises a tugboat body, a mooring rope, a stern roller, a shark jaw, a large tow, a superstructure, an anchor windlass, anchors, bow propellers, a left propeller, a middle propeller, a right propeller and cushion tires. The tugboat body is formed by welding steel plates, the stern of the tugboat body is provided with the cylindrical stern roller, the superstructure is arranged on the upper surface of the main deck of the tugboat body, the anchor windlass is arranged in front of the superstructure, the anchors are arranged on the anchor windlass in a suspension mode through anchor chains, the large tow is arranged behind the superstructure, the shark jaw is arranged between the large tow and the stern roller, the midpoints of the large tow, the stern roller and the shark jaw form a straight line, the bottom of a bow is provided with the bow propeller, the bottom of the stern is provided with the left propeller, the middle propeller and the right propeller from left to right, and the periphery of the tugboat is provided with the cushion tires. Therefore, the novel small-sized tugboat solves the problems that the transportation costs are over-high, the turning is inconvenient and inflexible, long-term friction between the stern of the tugboat body and a tow line causes potential safety risks to transportation, the tow line is extremely prone to swinging from side to side during a towing process of the tugboat so that the direction of the tugboat is not easy to control and the like in many tugboats.

Description

technical field [0001] The invention relates to a small tugboat and belongs to the technical field of tugboats. Background technique [0002] Tugboats are used to tow ships or floating structures that have no power and cannot propel themselves. The tugboats have a small body but a large power. They do not carry cargo or passengers. Tugboats can be divided into ocean tugboats, inland river tugboats and port tugboats. Among them, ocean tugboats can be divided into ocean tugboats and coastal tugboats. With the exploitation of oil and other non-renewable resources in the world, many countries are turning their attention to the oceans with huge energy reserves, and developing deep-sea oil wells. The crude oil extracted from the sea must be towed regularly. It means that the demand for small and medium-sized tugboats will gradually increase, but at present, many working tugboats are transformed from previous coastal tugboats. After long-term use, it is found that these tugboats ha...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that many existing tugboats have high transportation costs, inconvenient turning, and inflexibility. The long-term friction between the stern of the hull and the tow rope has caused potential safety hazards in transportation, and the tow rope is very easy to swing left and right during the tugboat. Make the direction of the tugboat difficult to control, etc.
