Abstract

Skipspropellvippe som forsyner et skip (3) med oppløft- og nedsenkbare propeller (2) som er festet på vippens vinger (9), som igjen er festet til en bred vippering (1) som kan beveges rundt en skipsskrogfestering (12) montert eller sveiset fast til skipsskroget (3). Vippen beveges av en elektromotor (5) med et akslingshode (6) som griper inn i tenner (7) på vipperingens (1) oppside. Vipperingen (1) har kulelagre (8) i hele omkretsen mot skipsskroget (3). Vippevingene (9) er hule. Gjennom åpninger i vipperingen (1) og i vingene (9) går det akslinger (10) som overfører skipsmotorkraften til propellene (2).Ship propeller rocker which supplies a ship (3) with lifting and submersible propellers (2) fixed to the wings (9) of the rocker, which in turn is attached to a wide rocker ring (1) which can be moved around a ship hull mount (12) mounted or welded fixed to the hull (3). The rocker is moved by an electric motor (5) with a shaft head (6) which engages the teeth (7) on the upside of the rocker ring (1). The tilt ring (1) has ball bearings (8) throughout the circumference of the hull (3). The rocker wings (9) are hollow. Through openings in the tilt ring (1) and in the wings (9), shafts (10) transmit the ship engine power to the propellers (2).

Description

Oppfinnelsen angår en skipspropellvippe til bruk på skip. The invention relates to a ship propeller rocker for use on ships.

På dagens skip kaster propellen med stor kraft vannet i nesten rett linje bakover. On today's ships, the propeller throws the water backwards with great force in an almost straight line.

Ved denne i rett linje tilbakekastede vannet tapes det mye drivstoff fordi dette tilbakekastede vannet gir dårlig "fraspark" ved at vannet blir kastet mot vann som hele tiden er i hurtig bevegelse bakover som i en stor elv. With this water thrown back in a straight line, a lot of fuel is lost because this thrown back water gives a poor "kick-off" by the water being thrown against water which is constantly moving rapidly backwards like in a large river.

Hensikten med oppfinnelsen er å rette opp det ovennevnte misforholdet, og derved minske drivstofforbruket for skip. The purpose of the invention is to correct the above-mentioned imbalance, thereby reducing fuel consumption for ships.

Dette oppnåes ifølge oppfinnelsen ved at de to propellene vekselvis blir løftet opp og ned slik at det innsugde vannet, som blir kastet ut med stor kraft, nå treffer mye mer stillestående vann - i stedet for vann i hurtig bevegelse bakover. According to the invention, this is achieved by the two propellers being alternately lifted up and down so that the sucked-in water, which is ejected with great force, now hits much more stagnant water - instead of water moving rapidly backwards.

Det som oppnås i forhold til teknikkens stilling er at når de to propellene er i drift på den bevegelige vippen, som vipper dem sakte opp og ned, vil propellene få mye mer fremdriftskraft i det stadig nye stillestående vannet vippen fører dem til. What is achieved in relation to the state of the art is that when the two propellers are in operation on the movable rocker, which tilts them slowly up and down, the propellers will gain much more propulsive power in the ever-new stagnant water that the rocker leads them to.

Skipspropellvippen ifølge oppfinnelsen er vist på tegningen, der figur 1 er et riss sett ovenfra, figur 2 viser et tverrsnitt av vipperingen og dens innside. The ship propeller rocker according to the invention is shown in the drawing, where figure 1 is a view from above, figure 2 shows a cross-section of the rocker ring and its interior.

Vippen (9) går rundt en stålsylinder som er festet til skipsskroget (3) med stålskruer (14) eller er sveiset fast til skipsskroget (3). Vippen (9) har kulelagre (1) i hele omkretsens i fremre del. Vippens vinger (9) har propeller (2). Disse propellene (2) kan løftes opp og ned ca. 110 grader i forhold til vipperingens (1) midtpunkt. Elektromotoren (5), som er plassert inni skipsskroget (3) ved vippens (1) fremre del, driver vippen (1) ved at akslingshodet (6) griper inn i tennene (7) oppå vipperingens (1) fremre del mot skipsskroget (3). Rundt vipperingen (1) mot skipsskroget er der plassert et lokk over tennene (7) og elektromotorens (5) tannhjul (6). Dette lokket (11) som er skrudd fast med stålskruer (14) er åpent på tegningene fig. 1 og fig. 2 for å vise hva som er under det. The rocker (9) goes around a steel cylinder which is attached to the ship's hull (3) with steel screws (14) or is welded to the ship's hull (3). The rocker (9) has ball bearings (1) around the entire circumference in the front part. The tilter's wings (9) have propellers (2). These propellers (2) can be lifted up and down approx. 110 degrees in relation to the center point of the rocker ring (1). The electric motor (5), which is located inside the ship's hull (3) at the forward part of the tilter (1), drives the tilter (1) by the shaft head (6) engaging the teeth (7) on top of the forward part of the tilter (1) towards the ship's hull (3 ). Around the rocker ring (1) towards the ship's hull, there is a cover over the teeth (7) and the gear wheel (6) of the electric motor (5). This lid (11), which is screwed on with steel screws (14), is open in the drawings fig. 1 and fig. 2 to show what's underneath it.

Claims

1. Rocker (9) for use on a ship - lowers and raises the two propellers (2) characterized by the fact that a cylinder (12) made of steel or aluminum is mounted on the rear part of the ship (3) on which around this cylinder (12 ) a movable rocker (9) is mounted which can move on a ball bearing (1) on the cylinder (12) with a propeller (2) at each outer edge.

2. The rocker (9) according to claim 1, characterized in that the rocker (9) with the two propellers (2) alternately moves up and down 110 degrees.

3. Rocker (9) according to claims 1-2, characterized in that an electric motor (5) acts on a shaft drive head (6) which moves the rocker up and down by engaging teeth (7) in the middle part of the rocker (9) around the cylinder ( 12).
