Embodiment 1

[0047] refer to figure 2 , 3 , the electric push boat includes a hull 1, a propeller 2 and a rudder 3.

[0048] The propeller 2 is connected to the tail of the hull 1 in rotation around its own axis, and is located in the middle of the width direction of the hull 1 , and the axis of the propeller 2 is parallel to the length direction of the hull 1 . When the ship sails, the propeller 2 rotates to generate a backward water flow, and the reaction force of the water flow pushes the ship forward.

[0049] Two tail rudders 3 are arranged side by side, and the two tail rudders 3 are distributed along the width direction of the hull 1; When the ship is sailing, the steering of the ship is realized by controlling the deflection of the stern rudder 3 .

[0050] refer to figure 2 , 3 , The electric push boat also includes a steering assist device located at the tail of the hull 1. When the ship turns, the steering assist device causes the hull 1 to generate a deflection moment t...

Embodiment 2

[0069] refer to Figure 7 , 8 , the difference between this embodiment and embodiment 1 is that

[0070] Limiting member 9 includes sliding seat 94; Specifically, the bottom of the hull 1 can be provided with a dovetail groove, and the upper end of the sliding seat 94 can be provided with a dovetail block, and the dovetail block is slidably embedded in the dovetail groove.

[0071] The sliding seat 94 is provided with a limiting groove 941 , the extending direction of the limiting groove 941 is perpendicular to the rotation axis of the water spray pipe 8 , and the extending direction of the limiting groove 941 is perpendicular to the sliding direction of the sliding seat 94 .

[0072] The collar 71 connected to the water spray pipe 8 is slidably embedded in the limiting groove 941 , and the outer periphery of the collar 71 is provided with a limiting surface 712 , and the limiting surface 712 is slidably attached to the sidewall of the limiting groove 941 .

Abstract

This application relates to an electric push boat, including a hull, a propeller stern rudder, a water inlet pipe, a steering pipe and a driving part; the propeller rotates around its own axis and is connected to the tail of the hull, and is located in the middle of the width direction of the hull; the water inlet pipe is fixedly connected to the hull , the axis of the water inlet pipe coincides with the axis of the propeller, and the water inlet pipe is sleeved on the outer periphery of the propeller; one end of the steering pipe is connected to the end of the water inlet pipe away from the hull head, and the steering pipe is connected to the water inlet pipe by rotation, and the rotation axis of the steering pipe is in line with itself There is an angle between the axes; the drive part is used to drive the steering tube to rotate. When controlling the steering of the ship: on the one hand, the stern rudder deflects; on the other hand, the driving part drives the steering pipe to deflect around its rotation axis, so that the end of the steering pipe away from the water inlet pipe is located on the side of the water inlet pipe axis, and the water flows from the steering pipe. and produce a reverse force to make the hull generate a deflection moment, and the deflection moment cooperates with the deflected tail rudder to accelerate the ship's steering and reduce the ship's steering radius.

Description

technical field [0001] The present application relates to the field of ships, in particular to an electric push boat. Background technique [0002] An electric push boat (electric propulsion boat) is a propeller driven by an electric motor to propel the boat to sail. The electric propulsion method provides an application path for high-quality ships with its environmental protection and energy-saving technical advantages. [0003] refer to figure 1 , the ship includes a hull 1, a propeller 2 and a rudder 3. [0004] The propeller 2 is rotatably connected to the tail of the hull 1 , and the rotation axis is parallel to the length direction of the hull 1 . Meanwhile, when only one propeller 2 is provided, the propeller 2 is located in the middle of the width direction of the hull 1 . [0005] The tail rudder 3 is rotatably connected to the tail of the hull 1, and the axis of rotation is vertical. When the ship is sailing, the steering of the ship is realized by controlling...
