Embodiment 1

[0018] The present invention provides a water-air integrated flipping propeller, such as figure 1 . A water-air integrated flipping propeller, comprising a motor shaft 102 driven by a motor 101, a vent pipe 103 externally meshed with a gear of the motor shaft 102, and an impeller 105 distributed at the tail end of the vent pipe 103 outer wall, located at the impeller The first 105 outer side is coaxial with the vent pipe one 103; the upper left side of the turbocharger 3 located in the middle of the propeller is connected to the vent pipe one 103, and the lower right side is connected to the vent pipe two 203, and the vent pipe two 203 and The second motor shaft 202 gear external meshing is driven by the second motor 201, the second impeller 205 is located at the tail end of the outer wall of the second vent pipe 203, and the second draft tube 204 is located at the outer side of the second impeller 205 and is coaxial with the second vent pipe 203. During normal operation as ...

Embodiment 2

[0020] In the harsh water environment where some small rescue boats work, the rescue boat will roll over. When the rescue boat rolls over, the air pipe 2 203 will enter the air, and the air pipe 1 103 will spray air. At this time, the impeller 2 205 is located above the water surface and loses its propulsion ability. The impeller one 105 is located below the water surface and is driven by the motor one 101 to rotate the motor shaft one 102, and the motion is transmitted to the impeller one 105 by the gear engagement of the motor shaft one 102 and the vent pipe one 103 to reach normal operation and advance.

Abstract

The invention discloses a water-air integrated turning propeller which can effectively improve the propulsion efficiency and propulsion speed of a ship. It is characterized in that it includes a vent pipe one, a vent pipe two, a draft pipe one, a draft pipe two, an impeller one, an impeller two, a motor one, a motor two, a motor shaft one, a motor shaft two, and a two-way supercharger. The vent pipe is connected with the two-way supercharger, which is divided into upper and lower parts, which are used for air intake and exhaust respectively; the motor is driven by the external meshing of the motor shaft and the vent pipe gear; the impeller is located at the end of the outer wall surface of the vent pipe; The snorkel is coaxial. The invention has a simple and ingenious structure, fully utilizes the mechanical characteristics of the gas-liquid two-phase fluid, effectively improves the propulsion efficiency of the boat, and is suitable for various small rescue boats and their use environments.

Description

technical field [0001] The invention relates to the field of boat propulsion, more specifically, to a water-air integrated reversing propeller. Background technique [0002] With the development of sea and air traffic, screw propellers have been widely used and recognized. Especially in the propulsion mode of ships and ships, the propeller has become the preferred propulsion mode. Screw propulsion mainly uses the force of propeller blades on water to obtain reverse propulsion, but when the propeller is running at high speed, the water flow will flow backwards fixedly, which will lead to the reduction of the reaction force from water obtained by the propeller . The thrust obtained by the propeller will not increase as the operating power of the propeller increases. This will seriously affect the propulsion efficiency and propulsion speed of the boat. [0003] For some small boats for emergency rescue, when the boat reaches the rescue position to carry out the rescue missi...
