Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a multi-directional adjustment auxiliary structure of a hull propulsion mechanism. Background Art

[0002] The draft of a ship generally refers to the depth of the ship immersed in water. It refers to the vertical distance from the bottom of the ship to the point where the hull connects to the water surface. It indirectly reflects the buoyancy of the ship during navigation (or the weight of the hull and its cargo, etc., because this is equal to the buoyancy of the hull). Therefore, the greater the draft of the hull, the greater the cargo carrying capacity of the ship.

[0003] When the hull is unloaded, the draft is shallow, the stern rudder blade and propeller are too shallow in the water, the rudder efficiency is reduced, the resistance on the bow increases, the operating performance is poor, and the energy consumption of the ship is increased. Summary of the invention

[0004] In order to overcome the problem in the prior art that the rudder efficiency of a ship is reduced due to the draft during sailing, the present invention provides a multi-directional adjustment auxiliary structure for a hull propulsion mechanism.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A multi-directional adjustment auxiliary structure for a hull propulsion mechanism, comprising:

[0007] A transverse slide rail, which is fixed at the rear end of the hull, and is provided with two transverse slide rails, and the two transverse slide rails are arranged in parallel; the upper and lower ends of the transverse slide rails are provided with grooves;

[0008] A slider, wherein one side of the slider is provided with a transverse slot, and the upper and lower slot walls of the transverse slot are provided with ridges, and the other side of the slider is provided with a vertical slot; the left and right slot walls of the vertical slot are provided with ridges;

[0009] A vertical slide rail, the vertical slide rail is fixed on the propulsion mechanism; the left and right sides of the vertical slide rail are provided with grooves;

[0010] Among them, the convex ridge of the horizontal groove on one side of the slider cooperates with the groove of the horizontal slide rail, the propulsion mechanism is provided with two groups, which are respectively located on the left and right sides of the rear end of the hull, and each group of propulsion mechanism is provided with an upper and lower slider, and the upper and lower sliders respectively cooperate with the two horizontal slide rails, and the convex ridges of the vertical grooves on the other sides of the two sliders cooperate with the grooves of the vertical slide rail, two hydraulic cylinders are provided in the middle position of the rear end of the hull, the rod body of the hydraulic cylinder is connected to the propulsion mechanism, and a plurality of positioning holes are provided on the vertical slide rail, and the direct distance between two adjacent positioning holes is equal to the height of the slider, and positioning pins are provided in the positioning holes, and the vertical slide rail is fixed to the slider by the two positioning pins.

[0011] Further technology of the present invention:

[0012] Preferably, the upper and lower sliders are connected by a connecting rod.

[0013] Preferably, a vertical baffle is provided above the hydraulic cylinder in the middle of the rear end of the hull.

[0014] Preferably, the propulsion mechanism is provided with four sliding blocks, which are distributed in pairs on both sides of the propulsion mechanism.

[0015] The present invention has the following technical effects:

[0016] When the hull has a shallow draft when unloaded or a deep draft at the bow causing the stern to tilt upward, the position of the positioning pin is adjusted to control the positional relationship between the vertical slide rail and the slider, so that the propulsion mechanism can be moved downward to a deeper draft and reduce energy loss. During driving, the hydraulic cylinder is adjusted to push the propulsion mechanism out of the rear end of the hull so that the propulsion mechanism extends out of both sides of the hull to increase the water absorption space and facilitate propulsion. When there is insufficient space, the hydraulic cylinder is retracted to retract the propulsion mechanism to the rear end of the hull to avoid obstruction caused by the extension.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to Figures 1-5 , this embodiment provides a multi-directional adjustment auxiliary structure for a hull propulsion mechanism, including:

[0026] Transverse slide rails 1, which are fixed at the rear end of the hull 11, there are two of them, and the two transverse slide rails are arranged in parallel; grooves are provided at the upper and lower ends of the transverse slide rails;

[0027] Sliders 2, one side of the slider is provided with a transverse notch, convex ribs are provided on the upper and lower groove walls of the transverse notch, and the other side of the slider is provided with a vertical notch; convex ribs are provided on the left and right groove walls of the vertical notch;

[0028] Vertical slide rails 3, which are fixed on the propulsion mechanism 12; grooves are provided on the left and right sides of the vertical slide rails;

[0029] Among them, the convex ribs of the transverse notch on one side of the slider cooperate with the grooves of the transverse slide rail. There are two groups of propulsion mechanisms, which are respectively located on the left and right sides at the rear end of the hull. There are two upper and lower sliders on each group of propulsion mechanisms. The upper and lower sliders cooperate with the two transverse slide rails respectively. The convex ribs of the vertical notches on the other side of the two sliders cooperate with the grooves of the vertical slide rail. There are two hydraulic cylinders 4 at the middle position of the rear end of the hull. The rod bodies of the hydraulic cylinders are connected to the propulsion mechanism. A number of positioning holes 5 are provided on the vertical slide rail. The distance between adjacent two positioning holes is equal to the height of the slider. Positioning pins 6 are provided in the positioning holes, and the vertical slide rail is fixed on the slider through the two positioning pins.

[0030] The contraction of the propulsion mechanisms on both sides by the hydraulic cylinders not only plays a role in facilitating passage;

[0031] More importantly, when the propulsion mechanism rotates and works, the position of the propulsion mechanism moves out of the hull, so that the water suction in the front of the propulsion mechanism does not suck the water generated behind the ship, avoiding the generation of a serious negative pressure in the underwater part behind the ship and having a backward dragging effect on the moving ship;

[0032] At the same time, the left and right hydraulic cylinders are controlled separately, and the telescopic lengths of the left and right propulsion mechanisms are different, so that the propulsion force is different relative to the distance of the hull, and the hull can be steered.

[0033] The two upper and lower sliders are connected by a connecting rod 7.

[0034] A vertical baffle 8 is provided above the hydraulic cylinder at the middle position of the rear end of the hull.

[0035] Four sliders are provided on the propulsion mechanism, and are distributed in pairs on both sides of the propulsion mechanism.

[0036] The propulsion mechanism is a propeller blade.

[0037] To cooperate with the propeller blade placed on both sides, a new hull structure is designed: including the flow guiding and water shielding plates 111 on both sides of the hull. The two ends of the flow guiding and water shielding plates extend out of the front end and the rear end of the hull, and the lower end of the flow guiding and water shielding plates extends out of the bottom of the hull. The front end and the rear end of the hull are flat inclined plates, and the bottom of the hull is a flat plate.

[0038] First, through the flow guiding and water shielding plates on both sides, the water flow is guided to the lower part of the hull. The front end of the hull is a flat inclined plate, and after the water flow impacts the flat plate, it quickly flows through the bottom of the hull, reducing the influence of the water flow on both sides of the hull.
