In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide the twin-screw propulsion device of a kind of boats and ships。
In order to solve above-mentioned technical problem, the technical solution of the utility model is: the twin-screw propulsion device of a kind of boats and ships, including two propellers being symmetrically set in both sides below stern, all it is connected through propeller shaft bracket between described propeller and hull, described propeller shaft bracket is made up of propeller boss and support arm, described support arm be shaped as herringbone, be cased with the rotating shaft for installing propeller driven by driving mechanism in described propeller boss, the outside of rotating shaft is cased with the axle sleeve that one end and hull are fixing between propeller boss and hull。
Preferably, described support arm is installed with, with the welding ends of hull, the backing plate that shape adapts with hull。
Preferably, the angle of described support arm is 60 °-90 °。
Preferably, described support arm is being 35 °-40 ° near the side of hull axis and the angle of perpendicular。
Preferably, the bottom of described propeller boss is provided with the horizontal armed lever that one end is fixing with hull, is provided with the rudder plate for turning to of propeller side between described horizontal armed lever and hull。
Preferably, it is provided with vertical keyset between described propeller boss and horizontal armed lever。
Preferably, described keyset is provided with arc gusset with the contact position of horizontal armed lever。
Preferably, reinforcement gusset it is provided with between described axle sleeve and hull。
Compared with prior art, this utility model has the advantages that the twin-screw propulsion device of these boats and ships on the quarter respectively fills a propeller in both sides, lower section, one propeller turns left, another propeller is turned right, towing tension is good, the speed of a ship or plane is fast, and wind resistance power is strong, and a propeller can also make boats and ships keep power when breaking down wherein；Lambdoid support arm good rigidly；Arc gusset with strengthen gusset and ensure that axle sleeve and hull, keyset consolidate with transverse direction armed lever and be connected；Backing plate can make support arm and Hull Welding more convenient, firm。
