Description

Ship Peuropelra's automatic shift structure

The present invention relates to an automatic shift structure of a ship propeller, and in particular, the propeller is exposed to the stern lower part of the hull on the water so that the state can be moved so that the propeller is exposed to the lower part of the hull by the inlet and outlet. It is to be shifted and stored.

In general, there are various types of small ships, such as people going forward simply by rowing and speeding up by installing propellers at the back of the ship, which are mainly used for leisure and transportation in rivers and lakes.

For small ships, the power generated from the engine (internal combustion engine or motor) installed on the inside of the hull can be transferred to the engine in the case of the power transmission shaft or to the flexible shaft in the case of a large motor, but the low horsepower motor is small in size. Without the flexible shaft, the propeller is integrated without the power transmission shaft. When the power is transmitted to the propeller, the propeller rotates to push the water to move the hull forward.

end As possible  This part Should explain  .)

These small ships are exposed to the power transmission shaft and propeller configured to be submerged in the water by being exposed to the lower part of the stern, there was a problem that deformed and damaged due to contact with foreign objects in the process of transporting them to the land. .

In addition, during the process of moving on the water while the power transmission shaft and the propeller are exposed, there is another problem that the foreign body is directly wound on the propeller while the propeller is in contact with the foreign object in the water.

The present invention prevents the propeller from contacting foreign objects in the water during the process of moving on the water while preventing the power transmission shaft and the propeller from contacting the surrounding foreign objects in the process of moving the small ship on land. will be.

In the automatic shift structure of the ship propeller according to the present invention, as shown in Figures 1 to 5, the propeller 20 exposed to the bottom of the stern 11 of the hull 10 constituting the vessel is the upper portion of the stern 11 It is configured to be shifted by the draw-out part 30 provided in the.

Here, the hull 10 is toward the lower portion of the stern 11 from the lower portion of the hull bottom 12

Figure pat00002
Settled groove 13 having a form is formed so that the propeller bracket 21 with the propeller 20 is configured to be inserted.

The propeller bracket 21 is supported so that the propeller 20 is stably rotated, and at the same time, the propeller bracket 21 has a function of preventing direct contact with foreign substances in the water or outside of water. Both sides of the side piece 212 is coupled to the upper and lower ends, respectively, the propeller rotating part 23 having a propeller 20 provided at the end of the drive shaft 22 in the both side pieces 212 is stably coupled have.

The other side between the upper and lower horizontal members 211 is rotatably coupled to the direction blade 24 having a function of adjusting the moving direction of the vessel.

The two side pieces 212 are formed integrally with the inclined protection piece 213 inclined toward the forefront at the bottom of the corner, when the foreign material in the water bumps during the process of moving on the water, while reducing the impact It is configured to be able to easily pass over foreign objects.

The inlet / outlet unit 30 allows the propeller bracket 21 to be drawn into the inside of the settling groove 13 or to be drawn to the outside of the settling groove 13 so as to prevent contact with foreign objects on the outside. A link portion 31 coupled to the front bottom surface and both side pieces 212 of the settling groove 13, and a rod-shaped pull-out portion 32 provided on the upper horizontal member 211 and the stern 11. Consists of

The link portion 31 has an upper portion of the link bracket 311 coupled to the front surface of the settling groove 13, and one side of the second row link 312 is rotatable on both lower sides of the link bracket 311. The other side of the second row link 312 is rotatably coupled to both side pieces 212 of the propeller bracket 21 so that the propeller bracket 21 is settled by a rod-shaped pull-out unit 32. 13) is configured to be easily moved into the interior.

The rod-shaped pull-out unit 32 includes a front rod 321 provided at one side of the upper horizontal member 211 and a rear rod 322 connected to the directional blade 24 at the other side of the upper horizontal member 211. Consists of.

Here, the front rod 321 is fixedly coupled to the lower portion of the upper horizontal member 211, the upper portion to pass through the first sealing boss 33 and the lift cylinder 331 provided in the settling groove (13). It is coupled and configured to be operated up or down by the lift cylinder 331.

The upper portion of the front rod 321 drawn out to the upper portion of the lift cylinder 331 is hinged to the lower portion of the fixing bracket 34 is configured to be easily drawn out of the state can be maintained.

The rear rod 322 is coupled to the upper portion of the directional blades 24 through the lower portion of the upper horizontal member 211, the upper portion penetrates through the second sealing boss 35 provided in the settling groove 13 It extends to the inner middle of the fixing bracket (34).

As the direction plate 323 is coupled to the upper end of the rear rod 322, and the control wire 324 is coupled to both ends of the direction plate 323, the direction plate (324) is tensioned by the tension of the control wire 324. 24) is configured to be interlocked.

When such a ship propeller first moves on the water, as shown in FIG. 2, the propeller 20 provided below the stern 11 is drawn out from the seating groove 13 by the inlet / outlet 30. By being present, the vessel can move on water.

When the ship is approaching or bumped into a foreign object rock or the like in the process of moving on the water, both side pieces 212 is in contact with the inclined protection piece 213 formed in the lower corner before contacting the propeller 20 As the propeller 20 prevents the propeller 20 from being deformed and damaged as it is, it is possible to prevent the net or the string from being directly wound as the propeller 20 is positioned to the rear of both side pieces 212.

On the other hand, when moving the land on the water, as shown in Figure 3, the propeller 20 provided in the lower portion of the stern 11 is maintained in the state that is introduced into the seating groove 13 by the lead-out portion 30 Therefore, it is possible to prevent the external foreign matter from contacting. At this time, when the front rod 321 is pulled upward by the lift cylinder 331, the upper horizontal member 211 coupled to the lower portion of the front rod 321 moves together, and at the same time the rear rod 322 is fixed. By being inserted into the bracket 34, the state where the upper and lower horizontal members 211 with the propeller 20 is introduced into the settling groove 13 of the stern 11 is maintained.
