Marine propeller capable of preventing wire winding

Abstract

The invention relates to a marine propeller capable of preventing wire winding. The marine propeller is improved based on a traditional control box, center pipe and propeller motor, that is, an electric wire winding preventing device at least used for connecting dynamic and static power supply wires is mounted between the control box and the center pipe; the electric wire winding preventing deviceat least comprises firs and second dynamic electric conductors mounted on the center pipe and capable of rotating along with the center pipe and mutually insulated; the first and second dynamic electric conductors are connected with positive and negative poles of the dynamic power supply wires; meanwhile, the control box is fixed with first static electric conductors correspondingly contacted with the first dynamic electric conductors and second static electric conductors relatively contacted with the second dynamic electric conductors; and the first and second static electric conductors aremutually insulated, and are connected with positive and negative poles of the static power supply wires. After the structure is adopted, the electric wire winding phenomenon of the marine propeller inthe use process can be effectively prevented, the electric connection reliability is improved, and the use safety of the marine propeller can be effectively improved.

Description

technical field [0001] The invention relates to a marine propeller, in particular to an anti-tangle marine propeller. Background technique [0002] On existing marine propellers, the power cord of the propeller motor is usually connected through the connection port of the control box, and then passed through the center pipe to be connected to the propeller motor. The steering of the hull is realized by driving the center tube to rotate through the handle connected to the control box; it is also realized by operating the button on the control box to make the motor in the control box rotate forward or reverse, and then drive the center tube to rotate through the transmission mechanism . When the central tube rotates, the propeller motor rotates with it, thereby realizing the steering of the hull. During this adjustment process, since the section of power cord (called dynamic power cord) located in the central tube needs to rotate with the central tube, that is, the dynamic p...

Problems solved by technology

During this adjustment process, since the section of power cord (called dynamic power cord) located in the central tube needs to rotate with the central tube, that is, the dynamic power cord rotates relative to the control box; while the section of power cord located in the control box (called the static power cord) is fixed relative to the control box, therefore, the central tube will cause the power cord to be entangled during the rotation process, which is very likely to cause poor contact between the power cord and the power supply or even disconnection from the power supply. It is also possible to cause poor electrical contact with the thruster motor, which in turn can cause the hull to stop moving

[0003] Simultaneously, when the control circuit of the thruster motor is arranged in the motor housing, the control line must also be connected to the operation button installed on the surface of the control box through the center tube. At this time, as the center tube rotates, the control line will also appear above entanglement
