Anti-wind propeller device

Abstract

The invention relates to the technical field of the power drive device of a ship, in particular to an anti-wind propeller device, which comprises a streamline support, a stern shaft, a paddle drum and propeller blades, wherein the stern shaft is fixed into the streamline support through a bearing; one end of the stern shaft is connected with an internal combustion engine output shaft, and the other end of the stern shaft is connected with the paddle drum. The anti-wind propeller device is characterized in that the back face of at least one propeller blade is provided with a strip anti-wind cutter, and cutting edges of the cutters face to the tangent directions of the propeller blades; the anti-wind cutters are parallel to the axis of the paddle drum, so that the resistance of the anti-wind cutters is the minimum in rotation. The winding articles are cut automatically by means of the rotation of the propeller, the anti-wind propeller device has the advantages of simple structure, convenience in installation, complete cutting and the like, and all kinds of accidents or faults caused by the fact that a propeller shaft is wound are effectively prevented.

Description

Technical field [0001] The invention relates to the technical field of power driving devices for ships, in particular to an anti-winding type propeller device that is convenient to install and safe to use. Background technique [0002] As we all know, the ship's propulsion device generally adopts the propeller method. The propeller is composed of a propeller drum and a propeller blade. The propeller is connected to the output shaft of the power machine through a transmission shaft. The transmission shaft is connected to the hull through a bearing, a bearing seat and a sealing device. The propeller joint is equipped with a ship stern tube or a beauty frame. The propeller shaft drives the propeller to rotate to drive the ship to sail. When sailing, the groove between the propeller drum and the ship stern tube or the beauty frame and the propeller drum is often covered by floating objects in the water The entanglement of fishing nets, cables, etc. affects the normal operation of th...

[0002] As we all know, the propulsion device of a ship generally adopts the propeller method. The propeller is composed of a propeller drum and a propeller blade. The propeller is connected to the output shaft of the power machine through the transmission shaft. There is a ship stern tube or a beauty frame at the connection of the propeller, and the drive shaft drives the propeller to rotate to drive the ship to sail. During navigation, the groove between the propeller drum and the ship stern tube or the beauty frame and the propeller drum is often covered by floating objects in the water. , fishing nets, cables, etc. are entangled, affecting the normal operation of the propeller, and sometimes causing damage to the propeller, loss of power of the ship, and major accidents
