Abstract

A hull propulsion mechanism multidirectional adjustment auxiliary structure, comprising transverse slide rails (1), sliding blocks (2), and vertical slide rails (3). Ribs at transverse groove openings on one side of the sliding blocks (2) fit grooves of the transverse slide rails (1). Two sets of propulsion mechanisms (12) are provided, respectively arranged on the left and right sides at the rear end of a hull. Each propulsion mechanism (12) is provided with upper and lower sliding blocks (2). The upper and lower sliding blocks (2) respectively fit with two transverse slide rails (1). Ribs at vertical groove openings on the other side of the two sliding blocks (2) fit grooves of the vertical slide rails (3). Two hydraulic cylinders (4) are provided in the middle position at the rear end of the hull. Rods of the hydraulic cylinders (4) are connected to the propulsion mechanisms (12). Several positioning holes (5) are provided on the vertical slide rails (3). The direct distance between adjacent two positioning holes (5) equals the height of the sliding blocks (2). Positioning pins (6) are provided in the positioning holes (5). The vertical slide rails (3) are fixed on the sliding blocks (2) by two positioning pins (6). By adjusting the positions of the positioning pins (6), the positional relations between the vertical slide rails (3) and the sliding blocks (2) are adjusted, thus allowing the propulsion mechanisms (12) to be moved downwards to increase draft.

Description

Technical field

The invention relates to the technical field of ships, in particular to a multi-directional adjustment auxiliary structure of a hull propulsion mechanism.

Background technique

The ship's draft generally refers to the depth to which the ship is immersed in water. It refers to the vertical distance from the bottom of the ship to the point where the hull connects to the surface of the water. It indirectly reflects the buoyancy of the ship (or the weight of the hull and its cargo, because it is equal to the buoyancy of the hull). Therefore, the greater the draught of the hull, the greater the capacity of the hull to carry cargo.

When the hull is empty, the draft is relatively shallow, the stern rudder blades and propellers enter too shallowly, the rudder efficiency is reduced, the bow resistance increases, the operational performance is poor, and the energy consumption of the ship is increased.

Preferably, the propulsion mechanism is provided with four sliders, which are distributed in pairs on both sides of the propulsion mechanism.

The invention has the following technical effects:

In the case that the no-load draft of the hull is shallow or the bow draft is deep and the stern is upturned, by adjusting the position of the positioning pin, the position relationship between the vertical slide rail and the sliding block can be controlled, so that the propulsion mechanism can be moved down to deepen the draft. , To reduce energy consumption. During driving, by adjusting the hydraulic cylinder, the pushing mechanism is pushed out of the rear end of the hull, so that the pushing mechanism extends out of both sides of the hull, increasing the water absorption space and facilitating propulsion. In the case of insufficient space, the hydraulic pressure is contracted The cylinder recycles the propulsion mechanism to the rear end of the hull to avoid obstructions caused by extension.

Vertical sliding rail 3, the vertical sliding rail is fixed on the propulsion mechanism 12; the left and right sides of the vertical sliding rail are provided with grooves;

Wherein, the protruding edge of the lateral notch on one side of the sliding block is matched with the groove of the lateral slide rail, the propulsion mechanism is provided with two groups, respectively located on the left and right sides of the rear end of the hull, and each group of propulsion mechanisms is provided with There are two upper and lower sliding blocks, the upper and lower sliding blocks are respectively matched with two horizontal sliding rails, and the ribs of the vertical notches on the other side of the two sliding blocks are matched with the grooves of the vertical sliding rails. Two hydraulic cylinders 4 are arranged at the middle position of the rear end of the hull. The rod body of the hydraulic cylinder is connected with the propulsion mechanism. The vertical slide rail is provided with a number of positioning holes 5, and the direct distance between two adjacent positioning holes is equal to the height of the slider. , There are positioning pins 6 in the positioning holes, and the vertical slide rail is fixed on the slider through two positioning pins.

The propulsion mechanism on both sides is contracted by the hydraulic cylinder not only to facilitate the passage;

More importantly, it is ensured that when the propulsion mechanism rotates, the position of the propulsion mechanism is moved out of the hull, so that the front of the propulsion mechanism will not absorb the water generated after the ship, so as to avoid serious negative pressure on the underwater part of the ship. It has the effect of dragging the moving ship backwards;

At the same time, the left and right hydraulic cylinders are controlled separately, and the lengths of the left and right propulsion mechanisms are different, so that the propulsion force is different from the hull, and the hull can be turned.

The upper and lower sliding blocks are connected by a connecting rod 7.

A vertical baffle 8 is provided above the hydraulic cylinder at the middle position of the rear end of the hull.

Four sliding blocks are arranged on the propulsion mechanism, which are distributed on both sides of the propulsion mechanism.
