Description

A double-push electric boat

technical field

A double-push electric boat relates to a boat, in particular to an electric boat.

Background technique

The propeller rotation plane of the traditional ship propeller is basically perpendicular to the forward direction of the ship, the area facing the water is larger, and the resistance is greater, especially at high speed. Due to the use of a single propeller, the turning torque is large and the stability is poor. Requires tail rudder for direction control.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a double-push electric boat with less resistance and convenient turning.

The technical scheme of the present invention is: a double-push electric boat, comprising a hull, a left propeller and a right propeller. The left propeller and the right propeller have the same structure, and they are symmetrically arranged on the left and right sides of the hull.

The concrete structure of left thruster is: left thruster comprises electric motor, propeller and square pipe. Square tube is surrounded by left plate, top plate, right plate and bottom plate, and right plate directly adopts the middle part of the left wall of hull. Both the top board and the bottom board are arranged horizontally, and the left board and the right board are vertically arranged vertically. The angle between the rotation plane of the propeller and the rear of the right plate is an acute angle, and the acute angle is not more than 50°. The plane of rotation of the propeller is all perpendicular to the top plate and the bottom plate of the square tube. The square tube fits compactly with the propeller. Driven by the electric motor, the propeller can flexibly rotate in the square tube.

The propeller of the left propeller and the propeller of the right propeller have the same structure and turn to the opposite direction. Adjusting the rotation speed of the propeller of the left propeller and the propeller of the right propeller can control the heading of the ship.

The advantages of the double-push electric ship of the present invention are: compared with the traditional propeller ship, the efficiency is high, the resistance is small, and the stability is good, especially at high speed, the resistance is smaller than the traditional ship.

detailed description

The present invention is described below in conjunction with accompanying drawing: With reference to accompanying drawing, a kind of double-push electric boat comprises hull 1, left propeller 2 and right propeller 3. The left propeller 2 and the right propeller 3 have the same structure, and they are symmetrically arranged on the left and right sides of the hull 1 . The concrete structure of left propeller 2 is: left propeller 2 comprises motor 21, propeller 22 and square pipe 23; Motor 21 adopts lithium battery to supply power; The middle part of the left wall of the hull 1 is adopted; the top board and the bottom board are arranged horizontally, and the left board and the right board are vertically arranged; the angle α between the rotation plane of the propeller 22 and the right board is 40°; Both the top plate and the bottom plate of the square tube 23 are vertical; the square tube 23 is closely matched with the propeller 22; driven by the motor 21, the propeller 22 can flexibly rotate in the square tube 23. The propeller 22 of the left propeller 2 and the propeller structure of the right propeller 3 have the same structure and turn to the opposite. Adjusting the rotation speed of the propeller 22 of the left propeller 2 and the propeller of the right propeller 3 can control the heading of the ship.

Described double pushing electric boat produces beneficial effect like this: the electric motor that starts left propeller 2 and right propeller 3 drives respectively the propeller 22 of left propeller 2 and the propeller rotation of right propeller 3. As far as the left propeller 2 is concerned: under the joint action of the propeller 22 and the square pipe 23, the water in the front is sucked into the square pipe 23 and then extruded from the rear of the square pipe 23. According to Newton's second law and Newton's third law, the left Thruster 2 generates thrust. When the rotating speed of the propeller 22 of the left propeller 2 and the rotating speed of the propeller of the right propeller 3 are the same, the electric boat will go straight, and the electric boat will turn when the rotating speed of one propeller is greater than that of the other propeller. Because the propeller is inclined, the area facing the water is small, and the resistance is small, and due to the effect of the square tube, the left propeller 2 and the right propeller 3 produce a mirror effect, and there is a hydrodynamic effect similar to that of an insect's jerk and sumo wrestling , so the propulsion efficiency is high. Because the propeller 22 of the left propeller 2 and the propeller of the right propeller 3 turn in the opposite direction, the torque can be offset, and the ship sails stably.
