Description

Apparatus for installing thruster

The present invention relates to an underwater installation device for a thruster, and more particularly, it is possible to accurately and safely induce vertical lowering or vertical elevation of the thruster, so that the operation of installing or removing the thruster in water is performed more easily and effectively than in the prior art. It relates to a possible, thruster underwater installation device.

Thruster is a device that allows floating hulls on the sea to resist currents and winds and to be stationary at a desired position or to move to a desired position.

In other words, when a ship or a similar floating body berths or docks at a pier, or when sailing at a low speed for turning in a small area, a thrust is installed vertically with the main axis on the bow to obtain propulsion in a horizontal forward direction, or for the purpose of performing business. It is installed in a suitable location. The realization of the operation consists in the operation of the propeller with propulsion and steering functions in the water at a position lower than the bottom of the hull.

The thruster's propellant mounted under the hull takes the method of inboard mounting through a trunk that goes underwater from the inside of the ship. In addition, there is a method of outboard mounting through the underwater route outside the ship.

The existing technology of mounting a thruster on the ship's side will be described.

First, after filling the trunk of the ship with water, the thruster is guided from the ship to the bottom mounting position using a fixed guide rail. Next, the thruster is temporarily fixed underwater, then the water in the trunk is scooped out and the fixing bolts are tightened.

When detaching, go through the procedure in the reverse order of mounting and lift it above the water surface according to the guidance of the fixed rail.

However, in the case of this prior art, there are the following problems.

That is, the fixed guide rail of the thruster has a problem of making the space of the trunk narrow. The reason is that the fixed guide rail is integrated with the hull and is arranged at the outer end point of the watertight fixing plate of the thruster, so it has a problem of limiting the expansion of the space inside the trunk, which hinders the use of space to arrange traffic and peripheral equipment. The space required for the passage system, equipment, ventilation, etc. is composed of a separate isolated structure space.

At this time, when moving the thruster up and down in water, there is a problem that the thruster is stuck in the distance space between the rails, which causes an accident to stop or lose balance during movement.

The phenomenon is that when the thruster moves underwater, if it loses the horizontal balance between the four or more rails guiding its way, the gap between the rail and the moving frame surrounding the rail bites the rail, causing a problem that it cannot move. A solution is required. This problem even causes a serious problem that prevents the thruster from seating in a watertight position, and the watertight fixing plate of the thruster does not exactly match the bolt hole position to be fastened. Even if the thruster watertight fixing plate is guided to the position to be fixed, it is difficult to precisely match it over the bolt hole to be fastened.

The vertical descent of the thruster 1 corresponds to the operation of installing the thruster 1 underwater as the thruster 1 has moved from the upper solid line to the lower dotted line in FIG. 7. In this case, it is possible to accurately and safely induce the vertical descending of the thruster 1 by the action of the thruster lifting/lowering induction part 120 including the lifting/lowering steel wire 122, and thereby, the thruster 1 Can be seated in the mounting position.

Conversely, the vertical rise of the thruster 1 corresponds to the detachment operation of the thruster 1 in which the thruster 1 has moved from the dotted line at the bottom to the solid line at the top in FIG. 7. That is, when the thruster 1 is detached, it induces the vertical rise of the thruster 1 and lifts it above the water surface.

It is possible to further enhance the stable movement function of the thruster 1 by applying the thruster balancing unit 130 including the balancing steel wire 135 together with the induction of vertical descent or vertical rise of the thruster 1.

In particular, it is possible to provide an optimal working environment for the next process of draining water and fixing the thruster 1 after the thruster is seated underwater by having a temporary watertight fixing function through the thruster watertight fixing plate 114.

Looking at the specific structure of the underwater thruster installation apparatus according to the present embodiment, the underwater installation apparatus for the thruster according to the present embodiment includes a thruster room 110 as an exterior skeleton structure.

As previously described, the thruster 1 functions as a propulsion and steering. That is, as previously described, the thruster 1 is a device that allows a floating hull on the sea to resist current and wind and is stationary at a desired position or is mainly mounted on the bottom of a ship.

At the upper end of the thruster 1, a ring 152 to which the crane line 151 of the crane 150 is coupled is formed. A plurality of rings 152 are applied to be spaced apart from each other at the upper end of the thruster (1).

A thruster room 110 is provided for installation of the thruster 1. The thruster room 110 is a structure that is installed only when necessary for underwater installation (mounting) of the thruster 1. It is advantageous in securing space because it is possible to install devices and equipment necessary for the space such as the operator's passage staircase 142, the submersible pump 141, the pipe 143, the ventilation duct 144, and the power cable 145 without restriction.

A support for installing a thruster 112 is installed at the upper end of the thruster room 110. The support for installing the thruster 112 is a structure that is combined when lifting the thruster 1 and moving to the bottom of the underwater ship. Can be assembled on site.

A watertight thrust fixing plate 114 may be disposed at the lower end of the thruster room 110. The thruster watertight fixing plate 114 serves to fix the thruster 1 to the hull while preventing the inflow of seawater.

On the other hand, the thruster elevating guide 120 is connected to the thruster installation support 112, the thruster 1 and the thruster watertight fixing plate 114, and induces the vertical descending or vertical rise of the thruster 1 Plays a role. That is, the thruster 1 can be stably vertically lowered or vertically raised by the action of the thruster elevation guide unit 120.

In this embodiment, a plurality of thruster elevation guide units 120 may be arranged at equal intervals along the circumferential direction of the thruster 1.

The thruster elevating guide unit 120 is connected to the hydraulic jack 121 coupled to the support for installing the thruster 112, and the elevating steel wire 122 that is connected to the hydraulic jack 121 to induce the vertical elevating and descending of the thruster (1). ) And, the lower socket 123 coupled to the thruster watertight fixing plate 114, one side is fixed to the thruster (1) and the other side is guided to the elevating steel wire 122, elevating steel wire 122 When the thruster 1 vertically descends due to the action of the upper socket 124, the upper socket 124 is fitted and coupled to the lower socket 123.

The elevating steel wire 122 provides an environment in which the thruster 1 moves vertically down or vertically without jamming and without hitting the wall. Since the elevating steel wire 122 has a soft induction performance, the frictional area between the elevating steel wire 122 and the surface supporting the elevating steel wire 122 in the water is minimized and smoothed to double the smooth upward and downward guidance function.

The lower socket 123 is provided in the socket base 123a coupled to the thruster watertight fixing plate 114 and the socket base 123a, and chucking the elevating steel wire 122 passing through the upper socket 124 ( It includes a wire chucking member (123b) for chucking, and a guide protrusion (123c) extending from the socket base (123a) toward the upper socket (124).

In addition, the upper socket 124 has a protrusion receiving groove 124a in which the guide protrusion 124c is accommodated, and the inlet forms an open portion 124b so that the guide protrusion 124c is well inserted.
