Description
Technical field
A kind of application of double tail linear structures on ship is the utility model is related to, it is double using ship more particularly to one kind
The fishing boat of tail linear structure.
Background technology
The operating environment operating mode of seagoing fishing vessel is more complicated, and usually arrives off-lying sea and caught, thus will to endurance
Ask comparison high, and sometimes for the pursuit shoal of fish, it is also desirable to carry out quick sailing.Therefore, this requires fishing boat to a certain extent
Ship type has the characteristics of wave making resistance is small, propulsive efficiency is high, the speed of a ship or plane is fast.Main engine power required for ship, largely
Quality depending on the hydrodynamic performance of hull, therefore hull lines design directly affects the propulsive efficiency and endurance of ship.
On the other hand the propulsive efficiency of propeller can also be improved to reduce required main engine power, and then improve promoting comprehensively for ship
Performance, such as reduce the rotating speed of propeller, increase the diameter of propeller.But the conventional design carried out according to design specification, it is existing
Some fishing vessel designs are single buttock line type or conventional propeller strut type, only install a propeller.Single buttock line type is because drinking water limits, spiral shell
The diameter of rotation oar is very restricted, it is impossible to increases diameter to reduce rotating speed, thus to reach same propeller power, spiral
The diameter of oar is smaller, and rotating speed is higher, thus the propulsive efficiency of propeller is than relatively low.Meanwhile propeller strut ship type because fishing boat is stranded,
Rush beach and the reason such as hit a submerged reef, cause the service life of propeller strut shorter.

A kind of fishing boat using the double tail linear structures of ship, from two small flat and arch composite line type structure, meet
Following parameter request：
450mm ＜ B ＜ 550mm,
1750mm<B1<1850mm,
9500mm<B2<1050mm,
350mm<B3<450mm,
Wherein, B is ship face width,
B1 is width of the ship midship to shaft centre line,
B2 is ship molded breadth,
B3 is rudder seat width.
One kind as above-mentioned technical proposal is improved, wherein also including the through hole for installation axle propulsion system.
One kind as above-mentioned technical proposal is improved, wherein the diameter of phi of the through hole meets following parameter,
330mm<Φ<350mm。
One kind as above-mentioned technical proposal is improved, wherein also including the rudder seat of installation propeller.
One kind as above-mentioned technical proposal is improved, and the thickness T of its centered rudder seat meets following parameter,
180mm<T<220mm。
Compared with prior art, the technical solution of the utility model has the double propulsion systems of double oars, adds Ship Propeling
Power, and do not limited by drinking water, the diameter of propeller can be improved, so as to be reduced in the case where ensureing that propeller power is constant
Rotating speed, the propulsive efficiency of the ship of raising.And due to the improvement of structure, make fishing boat in situation that is stranded, hitting a submerged reef and rush beach
Under, the service life of propeller strut is improved, so as to substantially increase the survival ability of fishing boat, has ensured the life and property of fisherman
Safety.
