DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a preferred embodiment of a real-time wave measuring apparatus and a dynamic load monitoring system of a ship including the same according to the present invention will be described in detail with reference to the accompanying drawings, Elements are denoted by the same reference numerals, and redundant description thereof will be omitted.

According to embodiments of the present invention, in order to acquire various wave information such as wave direction, cycle, and height in a dynamic load monitoring system of a ship, conventionally, measurement wave information acquired using a pressure gauge And thus it is possible to implement a new real-time wave measuring apparatus and a ship dynamic load monitoring system including the same.

FIG. 1 is a view showing a case where a real-time wave measuring apparatus according to an embodiment of the present invention is applied to a shell plating.

A real-time wave measuring apparatus and a dynamic load monitoring system for a vessel including the same according to an embodiment of the present invention include a socket 110 coupled to a shell of a hull 10, an adjustment plug rotatably coupled to a socket 110 120, and a sensing sensor 130 that is rotated by the adjustment plug 120 and rotated.

Referring to FIG. 1, a plurality of real-time wave measuring apparatuses 100 and 101 according to an embodiment of the present invention may be installed on an outer plate of the hull 10 at regular intervals.

The wave measuring apparatuses 100 and 101 according to an embodiment of the present invention are developed in accordance with the characteristics of a wave which is a dynamic load changing in real time. It is possible to greatly reduce the error between the actual wave information and the dynamic load monitoring system which can calculate the dynamic load of the ship in real time.

For reference, the pressure gauge can obtain relatively accurate measurement data when measuring the pressure in the still water, but it is very difficult to accurately measure the height (wave height) of the wave especially in the dynamic load wave. The reason for this is that in the case of a static load, the greater the pressure measured by the pressure gauge, the deeper the depth of the water can be understood. However, in the dynamic load, This is because it is impossible to distinguish whether the impact pressure is large due to the speed.

For example, environmental conditions such as bottom slamming or bow / stern panting, which are impact pressures on waves applied to the hull, can be expressed as water depths, which can be expressed as being several tens of meters below water depth.

Therefore, a new sensor capable of more precisely measuring information such as wave crest, wave period, and traveling direction is required. According to the present embodiment, the wave measuring apparatuses 100 and 101 are installed on the outside plate of the ship 10 as shown in Fig. 1 to measure whether or not the frozen portion of the ship 10 is immersed / The height, the period, and the direction information of the waves applied to the ship 10 can be obtained more accurately.

FIG. 2 is a schematic view of a real-time wave measuring apparatus according to an embodiment of the present invention, and FIG. 3 is a view showing a modification of the real-time wave measuring apparatus according to an embodiment of the present invention. FIG. 4 is a bottom view of a real-time wave measuring apparatus according to an embodiment of the present invention shown in FIGS. 2 and 3. FIG.

2 to 4, the socket 110 can be coupled to be fixed to the shell plating of the hull 10. To this end, the socket 110 may be welded or screwed to the shell plating of the hull 10. Therefore, the socket 110 can be easily separated from the shell plating of the hull 10 when maintenance is required.

The adjustment plug 120 may be rotatably coupled to the socket 110 so as to be rotatable around a virtual center axis X passing through the center of the socket 110. [ The socket 110 may have an opening 111 formed on one side of the socket 110 so that the adjusting plug 120 can be inserted therein. A thread may be provided corresponding to the thread. The shape of the opening 111 may correspond to the shape of the regulating plug 120.

The adjustment plug 120 is rotatable around a virtual central axis X with respect to the socket 110 fixed to the outer sheath of the hull 10. Accordingly, when the adjusting plug 120 rotates with respect to the socket 110, the detecting sensor 130 mounted on the adjusting plug 120 can be rotated together with the socket 110 as well. 8 and 9, the orientation of the detection sensor 130 can be adjusted as required, by rotating the detection sensor 130 in accordance with the rotation of the adjustment plug 120. [

This may cause an error in the information provided by the sensor 130 regardless of the presence or absence of seawater depending on where the detection sensor 130 is installed on the outer plate of the ship 10, It is necessary to adjust the placement direction or the placement angle of the detection sensor 130 as shown in Figs. 8 to 11. Fig.

In the case of this embodiment, the regulating plug 120 can be screwed into the socket 110. Specifically, the adjusting plug 120 includes a wrench hole 121 formed on one side (outer side) contacting the seawater and an adjusting plug rotation adjusting tab 122 protruding from the other side (inner side) opposite to the wrench hole 121, As shown in FIG.

The wrench hole 121 may be used to rotate the adjustment plug 120 using a wrench (not shown). Referring to FIGS. 2 and 4, a sensing sensor 130, which will be described later, may be rotatably coupled to the wrench hole 121. Since the wrench hole 121 is opened toward the sea water side (outside), the detection sensor 130 installed in the wrench hole 121 can be directly exposed to the sea water.

A protective member 123 may be additionally provided in the wrench hole 121 to prevent the detection sensor 130 provided in the wrench hole 121 from being damaged by contact with a wrench (not shown).

4, the protection member 123 may be disposed on both sides of the detection sensor 130 in the wrench hole 121 to prevent the wrench from contacting the detection sensor 130. Although a pair of the protection members 123 are disposed on both sides of the detection sensor 130 in the present embodiment, the present invention is not limited thereto. For example, the protective member may include a step formed in the inside of the wrench hole 121. In this case, the wrench can contact the detection sensor 130 due to the step difference.

The adjustment plug rotation adjustment tab 122 is formed to protrude from the other side (inward) of the opposite side of the wrench hole 121, and the protruded portion may be provided with a thread corresponding to the thread provided in the socket 110. Thus, the adjustment plug 120 can be rotated relative to the socket 110 via the adjustment plug rotation adjustment tab 122. [

At this time, a sealing member 112 may be further provided between the socket 110 and the control plug 120 to block the inflow of seawater. The sealing member 112 may be made of an elastic material or an inflatable material and may be formed in a ring shape to be installed on the adjustment plug rotation adjusting tab 122. [ The sealing member 112 may be made of, for example, an air bag structure, and the volume may be increased or decreased depending on the degree of the external pressure.

FIG. 3 shows a modification of the real-time wave measuring apparatus 100 according to an embodiment of the present invention. 3, the real-time wave measuring apparatus 101 is configured such that the adjustment plug rotation adjustment tab 122 of the adjustment plug 120 penetrates the other surface of the socket 110, As shown in FIG. Therefore, the operator located inside the hull 10 can adjust the rotation of the adjustment plug 120 through the adjustment plug rotation adjustment tab 122 on the inside of the hull 10 without having to move to the outside of the hull 10.

Although not specifically shown in the drawings, a slot may be provided at the upper end of the adjusting plug rotation adjusting tab 122, so that it can be utilized to rotate the adjusting plug rotating adjusting tab 122.

FIG. 5 is an enlarged perspective view of a sensing sensor in a real-time wave measuring apparatus according to an embodiment of the present invention. FIG. 6 is a perspective view of a real time wave measuring apparatus according to an embodiment of the present invention, Sectional view showing a detection sensor of the wave measuring device. 7 is a cross-sectional view showing a process in which seawater is introduced into a measurement core having an open structure and a spherical body in the measurement core is separated from the ground line by buoyancy.

Since the detection sensor 130 is mounted on the adjustment plug 120, it can be rotated together with the rotation of the adjustment plug 120. Accordingly, the detection sensor 130 is capable of adjusting the direction in which the detection sensor 130 is disposed through the rotation of the adjustment plug 120. This can be understood from FIG. 8 and FIG.

4 and 5, the sensing sensor 130 includes a measurement core 131 coupled to the wrench hole 121 of the regulating plug 120; A ground line 132 provided inside the measurement core 131; And a spherical body 133 which can be in contact with or not in contact with the ground line 132 depending on the presence or absence of seawater and is made of a material that can be electrically connected to the ground line 132 upon contact therewith. .

In this case, the measuring core 131 is rotatably mounted on the wrench hole 121 of the regulating plug 120 so as to be rotatable about a virtual orthogonal axis Y orthogonal to the imaginary central axis X Can be combined. Since the measuring core 131 is rotatable in the wrench hole 121, the direction in which the sensor 130 is disposed can be adjusted by rotating the measuring core 131. This can be understood from Figs. 10 and 11. Fig.

The operation principle of the detection sensor 130 will be described as follows.

The sensing sensor 130 uses the principle that the spherical body 133 having buoyancy floats or sinks in the measuring core 131 in accordance with the presence or absence of seawater. The spherical body 133, which is moved by buoyancy, The presence or absence of a wave can be detected by detecting a state of contact or non-contact with the touch panel.

6, when the sensing sensor 130 is not exposed to seawater, the spherical body 133 maintains contact with the ground line 132, so that the ground line 132 and the spherical body 133 are separated from each other, Can be maintained. In this state, a current flows between the ground line 132 and the spherical body 133, so that the sensing sensor 130 determines that no such wave exists and outputs an electric signal to the controller (not shown) have.

For reference, the controller analyzes information provided from the detection sensor 130 of the wave measuring apparatuses 100 and 101, converts the information into time information, and displays the time information on a monitor.

7, when the sensing sensor 130 is exposed to seawater, the spherical body 133 maintains a state of being in non-contact with (i.e., separated from) the ground line 132, 132 and the spherical member 133 is cut off. In this state, a current can not flow between the ground line 132 and the spherical body 133, so that the sensing sensor 130 can determine that such a wave exists and output an electric signal to the controller.

That is, as shown in FIG. 1, in a state where a large number of sensors 130 are attached to the outer shell of the hull 1 through the socket 110 and the regulating plug 120, The direction, the period, the height, and the area of the wave acting on the outer shell of the ship 10 can be analyzed in real time and displayed on the screen by analyzing the signals. In addition, the dynamic load monitoring system of a ship can analyze such information provided by a large number of sensors 130 to provide information useful for navigation in real time.

For this purpose, the measurement core 131 may be formed in a structure that seawater is opened so as to pass between the inside and the outside of the measurement core 131. The measuring core 131 may have a cylindrical structure and a plurality of through holes may be formed on the outer circumferential surface thereof to allow the inflow of seawater. In the case of this embodiment, the adjustment hole 134 of the horizontal direction adjusting unit, which will be described later, can be used as a through hole for circulation of seawater. 7 shows a case where the seawater flows into the measurement core 131 through the adjustment hole 134. FIG. However, the present invention is not limited thereto, and the structure of the measurement core 131 may be variously modified if seawater can be circulated.

The grounding line 132 may be configured as a pair inside the measuring core 131. [ The pair of grounding lines 132 can maintain contact with the spherical bodies 133 when there is no inflow of seawater. Although the present embodiment shows a case where the ground lines 132 are formed as a pair, the number of the ground lines 132 may be variously modified.

The spherical bodies 133 may have a circular bead shape, and may be made of a conductive material while having buoyancy. Therefore, it is possible to make contact with or contact with the ground line 132 depending on the presence or absence of seawater, and to pass the current in the contact state.

FIG. 10 and FIG. 11 are views illustrating a process of adjusting a placement direction of a detection sensor using a horizontal direction adjusting unit provided in a measuring core in a real-time wave measuring apparatus according to an embodiment of the present invention.

According to the present embodiment, the spherical bodies 133 provided inside the measuring core 131 are positioned in accordance with various factors such as the angle and direction of the installation of the detection sensor 130 on the outer shell of the hull 10 Contact with the ground line 132 regardless of the presence of seawater. Therefore, it is necessary to adjust the placement direction or the placement angle of the detection sensor 130 as shown in FIG. 8 to FIG. 11 because an error may occur in the information provided by the detection sensor 130 due to these variables.

8 and 9, since the adjustment plug 120 is rotatable around a virtual center axis X with respect to the socket 110 fixed to the outer shell of the hull 10, the adjustment plug 120 So that the orientation of the detection sensor 130 can be adjusted. In this case, the adjustment plug 120 can be rotated so that the imaginary orthogonal axis Y arranged in the longitudinal direction of the measuring core 131 lies on a horizontal line when viewed from the drawing.

10 and 11, the spherical bodies 133 are separated from the inner surface of the measuring core 131 by the pair of grounding lines 132 in the measuring core 131 Should be installed. In this case, the pair of ground lines 132 are located on a virtual line (not shown) in the horizontal direction across the right and left on the same height line.

10 and 11, the pair of ground lines 132 can be positioned on the horizontal line by rotating the measuring core 131 with respect to the wrench hole 121 of the regulating plug 120. In this case,

For this purpose, the real-time wave measuring apparatuses 100 and 101 may further include a horizontal direction adjusting unit that can rotate the measuring core 131 with respect to the wrench hole 121. The horizontal direction adjuster may include a plurality of adjustment protrusions or a plurality of adjustment holes 134 arranged on the surface of the measurement core 131 such that the measurement core 131 is positioned as shown on the right side of each of Figs. 10 and 11 Lt; / RTI >

The plurality of adjustment holes 134 can be utilized not only as a passage for circulating the seawater as described above but also for horizontally adjusting the placement direction of the measurement core 131. [ In this case, the operator inserts a separate pin member (not shown) into any one of the plurality of adjustment holes 134 and pushes it clockwise or counterclockwise (see arrows in FIGS. 10 and 11) 131).
