Description

{MODEL SHIP PERFORMANCE TEST EQUIPMENT}

The present invention relates to a model line performance test apparatus, and more particularly, to a model line performance test apparatus that automatically restrains a model line when it deviates from a path.

In order to evaluate the movement of the ship while the ship is navigating irregular sea, a model line drawn in the same form is made and SEAKEEPING TEST is performed in the tank.

At this time, the model line is moved in accordance with the tug installed in the tank. If the model line is tested in free Hangzhou in the tank, the propeller and the key of the model line are to be moved along the towing tank. However, the winch was installed in the frame installed on the towing train, and the line connected to the winch was connected to the model line. During the test, the line was loosened so that it could not influence the test.

Particularly, in the past, while the inner port performance test of the model line was carried out, the operator grasped the situation of the model line from time to time, and the winch was operated when the model line had a problem such as a deviation from the path. Therefore, there is a problem that it is difficult for the model line to move safely when a problem that can not be recognized by the operator on the model line occurs.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a model line performance test apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6. FIG.

1 is a view schematically showing a state in which a model line is coupled to a towing train in a water tank according to an embodiment of the present invention.

Referring to Fig. 1, a model line performance test apparatus 1 according to an embodiment of the present invention is installed so as to be located on the water surface below an opening formed in a train 3, which is a model line 5. The model line 5 is restrained so as to be freely movable in a standing frame 10 surrounding the opening of the towing train 3. [

As shown in Fig. 1, the water tub 2 is provided with rails on both side walls so that the tow truck 3 can move. Thus, when the towing trolley 3 moves along the rail, the model line 5 partially locked in the water filled in the water tray 2 moves along the trolley train 3. The model line 5 loosely connects the fixing line 30 to the supporting frame 10 of the towing train 3 so that the fixing line 30 does not interfere with the free standing test. However, since an unexpected situation may occur due to the flow of waves in the water tank 2, the model line performance test apparatus 1 automatically draws the model line 5 by effectively moving the model line 5 in the case of a path deviation or a dangerous situation.

FIG. 2 is a perspective view showing a train as an example of FIG. 1, FIG. 3 is a view showing a winder and a tension meter coupled to a support frame of a train, which is an example of FIG. 1, And Fig.

The model line performance testing apparatus 1 according to an embodiment of the present invention includes a winder 20, a fixed bar 30, a tension meter 40, and a controller 50. The model wire (5) is restrained to the fixed bar (30) connected to the winder (20). The model line performance test apparatus 1 measures the tension of the fixed line 30 coupled to the model line 5 to grasp the situation of the model line 5 and if necessary, The position of the model line 5 is changed by adjusting the length of the model line.

3, the take-up machine 20 includes a wire 23, a cylindrical rotary drum 21 for winding the wire 23, and a motor M for rotating the rotary drum 21. As shown in Fig. The winder (20) is fixedly coupled to the support frame (10) of the towing train (3). The winder (20) rotates the rotary drum (21) by using the rotating force of the motor (M) to wind or unwind the wire (23).

A plurality of fixed lines 30 are coupled to the model lines 5. As shown in Fig. 2, the fixing rods 30 are respectively coupled to the top and the stern of the model lines 5 to allow the model lines 5 to move stably. A winder 20 is installed on the support frame 10 located at the head or stern of the model wire 5 and fixed to the ring 25 at the end of the wire 23 wound on both winders 20 Respectively.

As shown in Fig. 2, the fixing ropes 30 coupled to both the right and left sides of the head or stern are coupled to the wires 23 of one take-up machine 20, A winder 20 can be installed. The winder 20 installed in each of the fixed ropes 30 can be operated according to the tension of each fixed rope 30. Further, the fixing line 30 may be connected to be wound on the rotary drum 21 instead of the wire 23.

The tension meter 40 is coupled to each fixed bar 30 to measure the tension of the fixed bar 30. When the model line 5 is safely moving without departing from the path, the tension line 30 is loosely loosened so that the tension is not large. However, when the path is separated or the structure is caught, the tension line 30 is tightened and tension is increased . Thus, the tension measuring device 40 measures a value at which the tension of the fixing line 30 changes and sends it to the controller 50. The tension measuring device 40 may be of various types, but a load cell capable of measuring the tension of the fixing line 30 can be used. The tension meter 40 can be connected to the model line 5 so that the tension meter 40 can be securely held in the fixing line 30 when the tension meter 40 is connected to the fixing line 30. [

The controller 50 receives the measured values from the plurality of tension meters 40 and grasps the state of the model lines 5. When the model wire 5 is to be forcibly moved, a signal for operating the motor M of the winder 20 corresponding thereto is generated to drive the motor M. Therefore, even if the operator can not check the state of the model line 5 through the controller 50, the model line performance testing apparatus 1 can automatically detect the state of the model line 5 even if the model line 5 is separated from the path, To move the model line (5) to the original operating track or to lift the model line (5).

The tension of the plurality of fixed ropes 30 may vary greatly depending on the position and the condition of the model wire 5. 4, the controller 50 receives the measured values of the tension meters 40 coupled to the plurality of fixed lines 30, determines the state of each of the fixed lines 30, The fixed line 30, on which the tension is measured, commands the rotary drum 21 of the winder 20 to rotate.

5 to 6 are views schematically showing movement of a model line according to an embodiment of the present invention.

When the model wire 5 unexpectedly leaves the path due to the problem of the propeller or the key of the model wire 5, some of the plurality of the fixed wires 30 may be strained as shown in Fig. The controller 50 instructs the wire 23 of the take-up unit 20 to be wound and the wire of the other take-up unit 20 23) is released so that the model line (5) can move to the trajectory.

6, when the plurality of fixed ropes 30 is measured to have a predetermined value or more, the controller 50 determines that the model line 5 is in danger of being damaged, So that the wires 23 of all the winders 20 are wound so that the model wires 5 are lifted.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
