Description

Underwater culvert type propeller propulsion plant

Technical field

The utility model belongs to underwater installation technical field, and in particular to a kind of underwater culvert type propeller propulsion plant.

Background technology

At present, with the development of all kinds of new and high technologies, especially superconductor, permanent-magnet material, fuel cell etc. Rapid development so that power technology motor technology is obtained compared with much progress, so that either people's livelihood field or military affairs Field, the pure electric propulsion on the water surface and underwater naval vessel all in development by leaps and bounds, throw by more pure electric propulsion of warship Enter practicality.

The content of the invention

For problems of the prior art, the utility model provides a kind of underwater culvert type propeller propulsion plant, Have the advantages that easy to use, quietness is good, highly reliable, convenient to install and maintain.

To achieve the above object, the utility model uses following technical scheme：

A kind of underwater culvert type propeller propulsion plant, the device includes propeller and dynamical system two parts, described dynamic Force system includes shell, stator, rotor and end cap, is fixedly installed between the stator and outer casing inner wall, the rotor point Cloth is in the inner side of stator, and the rotor is hollow cylindrical structure, and the inwall of the rotor forms tubular duct, in the stator Gap is left between rotor, forms sealed chamber by being sealed between stator, rotor and end cap, the propeller includes oar Leaf, the blade are the continuous blade of a piece of crescent, and the blade spiral wound is distributed in tubular duct, the blade Root and the madial wall of rotor fix, the root of the blade in the projection on the madial wall of rotor twist, in tubular Duct axis direction, described blade one end originate in one end of rotor, and the other end of blade terminates at the other end of rotor, in cylinder Shape duct axis vertical plane direction, the distribution mode of the blade are：From the initiating terminal of blade to clearing end with from scratch, from Small to arrive big and then from big to small, be finally distributed from small to the state of nothing, the inward flange spiral winding of the blade forms spiral Line, the helix form blade mesopore in the axis direction of tubular duct, and blade mesopore sets with rotor coaxial and in blade Hole axially through.

The dynamical system is electric system.

The blade is together or multiple tracks, the canoe all same of the multiple tracks blade, is spaced between multiple tracks blade There is gap and the spiral winding that is parallel to each other is arranged.The multiple tracks propeller blade that similar artillery bore is formed i.e. in tubular duct tangles Structure, how much it determines according to ship design performance requirement.

Compared with prior art, the beneficial effects of the utility model are：

1. the utility model uses driven by power, by electrical machine working mode, driving culvert type propeller rotates, spirally Blade cuts water body, using reaction force, promotes naval vessel.The device is in use, reduces the energy in traditional propulsion mode Conversion links（It is mostly mechanical structure）, reduce the consumption of energy, comparatively environmentally friendly, the device directly significantly reduces Mechanical structure in conventional ship power set, naval vessel space availability ratio is added, add naval vessel quietness, there is structure letter It is single, using it is simple, operating efficiency is high, reduce operating noise, good reliability, it is convenient to install and maintain the advantages that, be especially suitable for all kinds of Civil and military naval vessel uses.2. the rotor in the utility model in culvert type propeller and dynamical system is combined as a whole, contain Road wall outer layer is rotor structure, and duct wall internal layer is propeller arrangement, it is had the duct of rotor structure and propeller arrangement concurrently Formula propeller instead of the rotor of motor completely, and when in use, shell also functions to the effect of radome fairing simultaneously, in favor of reducing water Resistance during lower motion；End cap plays a part of fixed, spacing, slip, sealing, is produced in stator and rotor normal work Heat by shell and duct, directly swapped with the water body outside propulsion plant and in duct, improve reliability.3. just Often during work, because blade is bidirectional screw stereochemical structure, propeller is lateral cutting water body, and screw propulsion is caused instead to make Ship Motion is enforced, the generation of its reaction force is being stepped up, controllable, in addition, in the utility model device, spiral shell Revolve the rotation of oar and promote Ship Motion, carried out in duct so that blade will not in noise caused by cutting water body Transmission is directed out, must outwards be transmitted just now after the filtering of the present apparatus, such as set up silencing equipment in the duct inwall of device Or material, then the noise of propeller cutting water body will be further compromised so that muting function of the naval vessel during navigation also phase To preferable, and due to the reduction of mechanical transmission structure, synchronously reduce ship noise source, add the navigation quietness on naval vessel When energy, especially low-speed running, effect is more preferable.In addition, in duct blade mesopore setting so that when running at high speed, also can The effect of certain elimination supercavity is played, can further improve the quietness on naval vessel.
