Problems solved by technology

Installing it on a ship can make the ship sail in shallow water areas, and also in water plants, floating garbage areas, and semi-water mud areas. Not good, because the force on the fins is not balanced enough, the draft of the fins and the hydraulic area generated are small, and the driving force generated is small, so the speed of the boat is not fast

Abstract

The invention discloses a semi-submerged propeller. The semi-submerged propeller comprises a runner a (1) and a runner b (2), as well as more than two groups of paddle board assemblies (3) which are uniformly distributed relative to the runner a (1) and the runner b (2), wherein the positions of axle centers of central rotating shafts (8) of the runner a (1) and the runner b (2) are staggered relatively; the runner a (1) is embedded in a bearing (12) through a paddle board rotating shaft a (6) and connected with the paddle board assemblies (3); and the runner b (2) is embedded into the other bearing (12) through a paddle board rotating shaft b (7) and connected with the paddle board assemblies (3), the central rotating shafts (8) are arranged at the centers of the runner a (1) and the runner b (2), and the central rotating shafts (8) are connected with a power output device or input device. The semi-submerged propeller disclosed by the invention can be mounted on a ship, paddle boards can always vertically enter water, the energy of the water can be fully utilized, and the speed of the ship becomes faster; and the semi-submerged propeller has the advantages of good stability, low cost and convenience in maintenance, and can be simultaneously used as a power device to be further expanded to the fields of hydraulic turbines, low-water hydraulic power generation, tidal power generation, ocean current or sea current power generation and the like.

Description

technical field [0001] The invention relates to the field of thrusters, in particular to a semi-submerged thruster capable of increasing the hydraulic area. Background technique [0002] At present, the propellers commonly used in ships and warships are water jet propellers or propeller propellers. The propeller propeller rotates after being powered by the ship's power plant, pushes the water to the back of the ship, and uses the reaction force of the water to push the ship forward. The propeller is simple in structure, light in weight and high in efficiency, and is protected only when it is installed below the waterline. If propeller propellers are used in shallow water ships, it is difficult for the ship to navigate in water plants, floating garbage areas, and semi-water sludge areas, because it is easy to cause water plants, garbage, etc. to attach to the propeller or damage the propeller, so that the propeller cannot operate normally; In the lower shallow water area, t...
