Vortex propeller of outboard engine

Abstract

The invention discloses a vortex propeller of an outboard engine. The vortex propeller comprises a shell body and a driving longitudinal shaft connected with an engine, a water inlet is formed in the lower portion of the front end of the shell body, a flowing channel extending from the water inlet is formed, a water outlet communicated with the flowing channel is formed in the rear end of the shell body, a helical impeller connected with the lower end of the driving shaft is arranged on the inner side of the water inlet, and a flow guide plate capable of rotating relative to the shell body is arranged on the rear side of the shell body. The three work states of a forward gear, an idle gear and a reverse gear are achieved with the flow guide plate blocking the area of the water outlet, the gear adjustment of the flow guide plate is controlled by a gear shifting handle, the overall structure is simple, and the operation is convenient. Meanwhile, due to the fact that the water inlet is designed in the lower portion of the shell body, the water inlet of the propeller is almost flush with the bottom of a ship when the propeller is arranged on a ship body, power can be obtained in the whole process as long as the water depth is larger than the immersion depth of the ship in the navigation process, the threat of submerged rock is avoided as far as possible, and the ship can navigate normally on shoal.

Description

technical field [0001] The invention relates to an outboard motor propeller. Background technique [0002] The emergence of outboard motors has provided great convenience for human water transportation. People can easily drive boats to their destinations without considering whether they have enough physical strength and skills to control the traditional methods of poles, oars and sculls. propulsion tool. However, the outboard motor has an unavoidable shortcoming. In order to ensure the propulsion efficiency, the propulsion part of the outboard motor is lower than the bottom of the ship. This means that the outboard motor will not be able to provide power in waters that are too shallow, such as swamps with countless shoals; and when navigating in shoals, once it hits objects such as reefs and tree stumps under the water surface, it will lose power at least slightly. cause personal injury.

However, the outboard motor has an unavoidable shortcoming. In order to ensure the propulsion efficiency, the propulsion part of the outboard motor is lower than the bottom of the ship.

This means that the outboard motor will not be able to provide power in waters that are too shallow, such as swamps with countless shoals; and when navigating in shoals, once it hits objects such as reefs and tree stumps under the water surface, it will lose power at least slightly. cause casualties
