Abstract

The utility model discloses a propeller of steaming powered ship which can propel the ship for navigating through the steaming power to overcome various defects of the existing engine propeller. The propeller comprises a steam boiler and a propeller. The propeller is installed on the ship bottom plate. The propeller cylinder arranged at the upper end is connected with the steaming pipe of the steam boiler, and the propeller nozzle arranged at the lower end is in expanding shape. An opening is transversally arranged, and the propeller is also provided with a steering mechanism. The utility model directly performs work by making use of the high pressure steam, so the thrust force is large, speed navigation is fast, and the mechanical efficiency is high. The steaming powered propeller which can replace the ship steering rudder can rotate at 360 degrees any angle, so the ship steering rudder device can be saved. The utility model which has the advantages of small volume, simple structure, low production cost, and easy installation can be installed at anywhere of the hull. The fire coal steaming powered boiler with high efficiency is adopted, so the navigation cost is reduced. The utility model is suitable for the underwater navigation in various surroundings, so the defect of the propeller winding can be remedied.

Description

The steam power marine propeller

Technical field

The utility model relates to marine propulsion, relates in particular to the propeller device for vessel that a kind of steam power advances ship's navigation.

Technical background

In the existing ship engine installation, ship power plant is mainly based on combustion engine, and diesel machine efficient is low, and effective power is about 30%, most heat that fuel produced consumes from waste gas, mechanical friction, and especially piston exhaust gas discharged and water tank cooling vessel are taken away a large amount of heats.And in propeller system, propeller system displacement based on propeller is little, overall dimensions are big, thrust a little less than, and to improve the propelling thrust of propeller, have only revving up, increase displacement, improve drainage speed, but after drainage speed improves, increase turbulent flow thereupon, increased resistance relatively, reduced mechanical efficiency, in order to address this problem, the normal employing increases the straight warp of propeller or a plurality of undersized propeller is installed, owing to be subjected to the influence of hull structure and draft and underwater topography situation, the size that increases propeller is restricted.Simultaneously, in existing ship yaw rudder device, major part is that propelling unit is separated with yaw rudder, has increased hull resistance, has increased manufacturing cost and operation easier, makes construction of vessel comparatively complicated.

Summary of the invention

The deficiency that the utility model closes and exists at ship power plant and propeller system and rudder unit proposes a kind of steam power marine propeller.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:

A kind of steam power marine propeller is characterized in that: comprise steam boiler, propelling unit, propelling unit is installed on the boats and ships base plate, and the propeller barrel of its upper end is connected with the steam pipe of steam boiler, and lower end propelling unit spout is expanding, the opening horizontally set.

Described propeller barrel is fixed on the boats and ships base plate through hold-doun nut by cone bearing, is equipped with on the propeller barrel and turns to tooth, turns to tooth to be connected cooperation with a steering screw.

The described tooth that turns to is positioned at boats and ships base plate upper end, and the propeller barrel of its lower end is provided with the propelling unit dowel disc.

Be provided with steam regulating valve in the described steam pipe passage.

The steam pipe junction of described propeller barrel and steam boiler is provided with seal ring.

Described steam boiler comprises body of heater, chimney, water pump, electrical motor, blower fan, coal dust pump, Boiler Steam pipe, steam cock and body of heater inner burner.

Described Boiler Steam pipe vertically connects from the steam expansion chamber of steam boiler bottom, docks with the propelling unit steam channel, by steam cock control quantity of steam.

Advantage of the present utility model: (1) utilizes the high-pressure water vapor thrust of directly doing work big, and route speed is fast, the mechanical efficiency height.(2) the steam power propelling unit replaces the ship turning rudder; can do the arbitrarily angled rotation of 360 degree; saved boats and ships yaw rudder device, little, simple in structure, the low cost of manufacture, easy for installation of (3) volume can be installed in hull Anywhere; (4) adopt efficient fuel coal steam power boiler; reduce the navigation cost, (5) are suitable for all-environment submarine navigation, have remedied the defective that screw propeller often twines; (6) do not have the machinery injury, help protecting animal under water.

The specific embodiment

The utility model proposes the propeller device for vessel that a kind of steam power advances ship's navigation.Specifically form by steam boiler and Fu and propelling unit 15.

See shown in Figure 1: 1 steam boiler (coal-fired steam power boiler), 2 chimneys, 3 water pumps, 4 electrical motors, 5 blower fans, 6 coal dust pumps, 7 Boiler Steam pipes, 8 steam cocks, 9 seal rings (O-ring seal), 10 hold-doun nuts, 11 steering gears, 12 steering screws, 13 cone bearings (locating cone bearing), 14 propelling unit dowel discs, 15 propelling units, 16 propelling unit steam pipes, 17 propelling unit spouts, 18 boats and ships base plates, 19 propeller barrel, 20 propelling unit water diversing heads.

Described steam boiler is by body of heater 1, chimney 2, water pump 3, electrical motor 4, and blower fan 5, coal dust pump 6, Boiler Steam pipe 7, device such as steam cock 8 and body of heater inner burner constitutes.Referring to the applicant with " coal-fired steam power boiler " utility model patent of asking in saying.Simultaneously, the utility model also can adopt existing steam power boiler.

Described propeller barrel 19 is passed boats and ships base plate 18, and is fixed on the hull through hold-doun nut 10 by two cone bearings 13, turns to tooth 11 with the spline installation on the propeller barrel 19, and cooperates with steering screw tooth 12.

Described Boiler Steam pipe 7 vertically connects from the steam expansion chamber of coal-fired steam power boiler 1 bottom, docks with propelling unit steam channel 16, and quantity of steam is by steam cock 8 controls, and there are cushion rubber 9 sealings two pipe junctions.On propeller barrel, be provided with propelling unit dowel disc 14.

Described propelling unit spout 17 is the expanding spout.

The utility model steam powered ship propelling unit, its principle is: coal-fired steam power boiler 1, produce enough steam working pressures by fire coal, make high-pressure water vapor from 7 ejections of Boiler Steam pipe, after steam cock 8 is regulated, enter propelling unit steam pipe 16, arrive spout 17 and form anti-propelling thrust, promote boats and ships and advance.The needs of steering screw tooth 12 root a tree name navigation at any time, the rotating screw bolt tooth, the recoil direction of adjustment propelling unit spout 17 realizes ship turning.
