Abstract
The utility model relates to an engine propeller, in particular to a ducted propeller, which front is provided with a water inlet and end is provided with a water outlet, wherein the front end of the water inlet is sealed with a motor via a sealing ring, the back end of the water inlet is provided with stabilizing and bearing mounts which support a motor shaft provided with rotary blades. The utility model has novel design, reasonable structure, simple art, low noise, little resistance, long service life, low cost, easy operation, high safety and wide application for the power system of water transport tools as ship or the like.
Description
Technical field:
The utility model relates to a kind of Powerpush Unit, specifically a kind of duct propelling unit.
Background technology:
At present, the propelling unit that boats and ships use mostly adopts screw propeller as propulsion source, but screw propeller processing technology complexity, noise is big.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provides a kind of reasonable in design, simple in structure, easy to use, flexible, and result of use is good, the duct propelling unit that cost is low.
The technical scheme that its technical matters that solves the utility model adopts is a kind of duct propelling unit, the front portion that it is characterized in that duct is provided with water inlet, end is a discharge port, the front end of water inlet is closed with motor by seal ring in the duct, the rear end of water inlet is provided with current stabilization, bearing support in the duct, stent support motor shaft, and motor shaft is provided with rotating blade.
The utility model modern design, rational in infrastructure, technology is simple, and noise is low, and resistance is little, and is sturdy and durable, and cost is low, and is easy to use, safety.
Description of drawings:
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Among Fig. 1: 1, motor, 2, seal ring, 3, water inlet, 4, duct, 5, current stabilization, bearing support, 6, bearing, 7, helicallobe, 8, discharge port.
As can be seen from Figure 1, a kind of duct propelling unit, it is the sub warhead type.The front portion of duct 4 is provided with water inlet 3, and end is a discharge port 8.The front end of water inlet 3 is closed with motor 1 by seal ring 2 in the duct 4.Motor 1 is the low-speed big motor, and noise is low during work, and the surface of helicallobe 7 be difficult for to produce vacuum bubbles and is corroded on the motor shaft.The rear end of water inlet 3 is provided with current stabilization, bearing support 5 in the duct 4.Support 5 plays current stabilization and support motor axle.Bearing 6 is connected and fixed support 5 and motor shaft.Motor shaft is provided with rotating blade 7.Blade 7 processing technologys are simple, and area of thrust surface are big, can obtain bigger power and higher cruising speed under lower-speed state.The utility model water inlet preceding, discharge port after, during work, water is on the bow, stern forms difference of pressure, can effectively reduce the resistance of water, energy savings.
The utility model modern design, rational in infrastructure, technology is simple, and noise is low, and resistance is little, and is sturdy and durable, and cost is low, and is easy to use, safety.Being suitable for power systems such as boats and ships, warship, the water transportation of ship class uses.
