Description

Observation system of draft of water depth measurement equipment using ultrasonic sensor

The present invention relates to a system for observing draft changes of depth surveying equipment using ultrasonic sensors in the field of surveying technology, and a draft of depth surveying equipment using ultrasonic sensors used for geodetic surveys of coastlines, underwater terrain, or depth. By monitoring the change, the observed draft value is used as a correction value for the measured value measured by the depth surveying equipment, but the draft change of the depth surveying equipment using the ultrasonic sensor to minimize the rolling phenomenon of the surveying equipment. It relates to an observation system.

In general, as a method of measuring coastline, water depth, and seabed topography of rivers, coastal oceans, etc., the sound echo sounder proposed through rapid technological development has been widely used in recent years.

An echo sounder is a surveying device that emits an ultrasonic wave to a survey destination and uses the property that the ultrasonic wave reaches the survey destination and is reflected and returned to the same path, and the measured data is used as an underwater topographic map, and recently, an underwater port facility It is also used for safety inspection of underwater structures such as bridges and bridges.

The echo sounder is classified into a single beam or a multi-beam according to the number or type of sensors provided, and when measuring the depth or topography of seawater in the irradiation method using ultrasonic waves, ultrasonic waves according to the temperature, salt concentration and water pressure of the seawater Since the moving speed of is different, the observed value should be corrected using the physical characteristics of the seawater for the depth.

The conventional echo sounder descends from the ship (the mothership) and emits an acoustic signal through the sensor arranged while the vessel moves while being disposed in the water, and receives and re-receives it to observe and record the depth and the seabed terrain. If one sensor is installed in the vessel, it can narrow the range because it can only sound at one point of the vertical bottom of the ship, but it has the advantage of relatively low price, light weight and small volume of the device. It is possible to simultaneously measure the whole seabed cross section of several tens to hundreds of points for transmission and reception range of more than 90 ~ 120 °, and also has an advantage over the sounding device with a single sensor in precision.

The data obtained by using the echo sounder is produced in black and white or color graphics with real-time depth of field or topographic map through a connected computer. .

As a conventional technology using such an echo sounder, Korean Patent No. 10-064592, Korean Patent No. 10-1008880 have been disclosed.

In this prior art, an echo sounder is installed on the bottom of the ship or on one side. Since the sounding range is narrow as described above, the sounding area that can be surveyed is narrowed as the ship moves once, and thus, in all the irradiation areas. In order to proceed with the survey work, there was a need to move the ship several times.

In shallow shallow waters such as coasts, ships cannot enter, so the echo sounder that transmits and receives ultrasonic waves is tilted in the direction of shallow waters and tilted to move the ship horizontally with the shoreline. If the angle of can not be adjusted in real time, there was a troublesome problem of having to raise the echo sounder to the ship and then lower it back into the water after adjusting the angle.

In addition, as a technology proposed to solve the above problems, Korean Patent No. 10-1073943 (multi-beam fixing device capable of vertical movement and rotation), and Korea Patent No. 10-1302177 (with a tilting means Dual multibeam sounding device) is disclosed.

The prior art is provided with a tilting means that can adjust the angle of the multi-beam transducer is capable of sounding more areas for a single movement of the vessel, the thrust and the resistance of sea water for the movement of the vessel Since it is made of a high-strength metal material to withstand, there is a problem that a high tension lifting device should be used to lift a multi-beam sounding device that is heavy and heavy.

In addition, there is a problem in that the coupling portion or the tilting means of the multi-beam transducer or the multi-beam transducer and the diving rod is damaged by the resistance of the sea water generated by the movement of the vessel.

In the prior art, since the power supply means for supplying power to the sound echo sounder and the sensor provided therein is disposed in the water while being coupled to the sound echo sounder, it is easily damaged by vibration generated during surveying, resistance by water pressure, and the like. There was a problem.

In addition, a conventional echo sounder or a ship has a rolling phenomenon that swings from side to side due to waves, currents, etc. in the state of being placed underwater or on the water surface. When such a rolling phenomenon occurs, an accurate correction value for correcting the measured value measured by the echo sounder is obtained. Because of the difficult problem, it was difficult to obtain accurate measurement values.

Do not.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the draft change observation system of the water depth measurement equipment using the ultrasonic sensor according to the present invention.

First, the draft change observation system (1) of the depth measurement equipment using the ultrasonic sensor according to the present invention is provided in the depth measurement equipment 70, which is equipped with an ultrasonic sensor and surveys the depth or the underwater terrain using the depth Observing the draft of the surveying equipment, using the detection value detected when a rolling phenomenon occurs by the wave surveying equipment or the ship as a wave or ocean current as a correction value for the measured value measured by the ultrasonic sensor.

At this time, the observation system of the present invention, the level holding means 10 and the depth sensor to minimize the rolling phenomenon of the depth surveying equipment 70, and to detect the exact depth of the depth surveying equipment 70 in real time when the rolling phenomenon occurs 20, the control part 30, and the dustproof means 40 are included.

The level maintaining means 10 is arranged in a direction in which the pair of symmetry mutually symmetrical to the depth surveying equipment is provided to lift in the opposite direction to minimize the rolling phenomenon of the depth surveying equipment,

To this end, one end is arranged to be close to or far from each other, a pair of frames 11 formed with an entrance 111 through which seawater passes,

A cover 12 for opening and closing the doorway 111,

Blocking film 13 made of a soft material to be folded or unfolded in accordance with the interval between the frames 11, respectively provided on both ends of the longitudinal direction of the pair of frames 11,

It comprises a rope 14 for connecting the frame 11 and the water depth measurement equipment (70).

The frame 11 is composed of a pair of one end is coupled to the hinge is configured so that the other end is close to or far from each other, made of a flat plate as a whole, the entrance 111 is formed through which the sea water passes.

Here, the frame 11 may be formed by bonding a plurality of supports to each other, but having a flat plate in the center and perforating the doorway 111 in the plate.

At this time, the number and location of the doorway 111 can be variously changed, and is formed to have a predetermined ratio according to the total area of the frame 11. Preferably, when the total area of any one of the pair of frames 11 is 100%, the doorway 111 is formed to have an area of 60 to 80%, more preferably 70 to 75% of the area It is formed to have.

The area ratio of the entrance and exit 111 is the seawater contained in the storage space (S) formed by the frame 11 and the blocking film 13 to be described later in a state in which the pair of the frame 11 is unfolded when the frame 11 descends The pair of frames 11 are close to each other while quickly exiting through the doorway 111, so that the optimal area does not form a resistance when descending.

On the other hand, the frame 11 is preferably formed of a metal that is light in weight and easy to mold while having less fear of corrosion due to salts contained in seawater. For example, the frame 11 is formed of stainless or stainless alloy. As another example, it may be made of a metal material coated with anti-corrosion heat treatment or anti-corrosion paint.

In addition, the frame 11 may be formed by arranging a porous mesh network in the center and welding a tube to the edge of the mesh network, wherein a hole formed in the mesh network is used as the doorway 111.

In addition, the frame 11 is further provided with a support plate 112 bent toward the outside at the top, the support plate 112 forms a resistance to suppress this when the frame 11 is raised, hinders this when falling It is formed to be bent in an oblique form gradually rising toward the outside so as not to form a resistance force.

The cover 12 is to open or close the doorway 111, and the frame 11 is disposed to close the doorway 111 when the frame 11 is raised and to open the doorway 111 when the frame 11 is lowered.

One end of the cover 12 is rotatably coupled to the frame 11, but is not particularly limited in material, but is preferably formed of a metal material or a synthetic resin material resistant to salt.

The blocking film 13 is provided at both ends of the pair of frames 11 in the longitudinal direction, respectively, and is made of a soft material to be folded or unfolded according to the interval between the frames 11, and the frame 11 is raised. When rotating so as to move away from each other at this time to prevent the movement of seawater between the frame 11 and at the same time to form a storage space (S) for storing the seawater between the frame 11 and stored in the storage space (S) Forming a resistance to suppress the rise of the frame 11 through the weight of the sea water.

The barrier layer 13 may be formed of a soft synthetic resin or cloth.

On the other hand, the barrier layer 13 is preferably to reinforce the edge and the center portion in order to prevent damage due to the rapid change in shape according to the weight of the sea water or the operation of the frame 11, for example, the portion that is combined with the edge A separate fixture is disposed to fix the barrier membrane, and the central portion may be formed in a state in which the cover is formed of silicon, which is strong in salinity and can be folded and unfolded.

The rope 14 is coupled to the frame 11 at one end so that the frame 11 can move while maintaining the horizontal state when the frame 11 is raised or lowered, and the other end thereof can be wound by a winding roller (not shown) provided in the ship. Combined.

As shown in the drawing, a plurality of ropes are coupled to the frame 11 and then bound together, which is more preferable to maintain horizontality when the frame 11 is raised or lowered.

At this time, the rope 14 may be further provided with a spacing maintenance hole 141 for maintaining the spacing between each rope (14).

The spacing holder 141 includes a ring 142 through which the rope 14 is inserted and a spacing bar 143 connecting the ring 142.

The spacing holder 141 maintains the spacing between the plurality of ropes 14 to prevent the frame 11 from rising in a folded state when the frame 11 is raised. That is, when the pair of frames 11 ascend due to the inclination of the depth surveying equipment rolling by the waves or currents may rise in the state of being close to each other, that is, folded state according to the direction of the waves or currents. In this case, there is a problem that can not achieve the purpose of the frame arranged to suppress the rise of the depth surveying equipment.

Therefore, in the present invention, in the pair of frames 11, at least one pair of ropes are coupled to each frame 11 so as to be disposed at a spaced apart position, and the spacer 141 for maintaining the spacing of the ropes. When the frame 11 ascends through the distance maintaining bar 143 constituting the spacing holding part 141 is to be able to rise in a distant state.

That is, when the frame 11 is raised, the rope 14 rises in the tensioned state, and in this case, the frame 11 is raised in the state in which both the upper and lower ropes are pulled on the basis of the spacing bar 143, When the frame 11 is lowered, the tension of the rope positioned downward based on the spacing bar 143 becomes a loose state, and thus does not prevent the frame 11 from being folded.

Therefore, when the frame 11 is raised, the pair of frames 11 are raised by the spacing bar 143 while the frame 11 is lifted up to the maximum by seawater while preventing the rising force. When the cover 12 is opened and descends, the seawater passes through the doorway 111 and at the same time the pair of frames are folded so as to be close to each other, thereby minimizing the resistance to hinder the falling.

The level holding means 10 made as described above is arranged in a direction in which the pair is symmetrical with each other in the water surveying equipment 70, as shown in Figure 3 and lift in the opposite direction.

That is, in FIG. 3, when the depth surveying equipment 70 is inclined in a form in which the right side rises, the frame disposed on the right side rises and the frame disposed on the left side descends.

At this time, the rising frame has a rising resistance is formed to minimize the inclination of the depth surveying equipment, and after the left side of the depth surveying equipment 70, the frame disposed below the left rises. While repeating these operations, a rise resistance that suppresses the rise of the depth surveying equipment is alternately generated from the left and the right to minimize the rolling phenomenon of the depth surveying equipment.

The depth sensor 20 is to be coupled to the rope 14 to detect the real-time water depth changed according to the position of the lifting rope to transmit it to the control unit 30 through the transmission module,

Coupled to the rope 14,

It is disposed inside the cylindrical housing 22 sealed inside through a partition wall enclosed in a circle,

The transmitting module 21 and a battery 23 for supplying power to the transmitting module 21 are disposed in the housing 22.

The support ball 43 is inserted into the support ball groove 422 and disposed to abut on the outer circumferential surface of the cap 41 inserted into the cap groove 421.

The cap 41 has one end opened and is inserted through one end of the rope, and a fixing bolt (not shown) for fixing the inserted rope 14 penetrates the cap 41 and the rope 14. Are combined.

At this time, the cap 41 is formed in a form of gradually narrowing the diameter toward the opening direction of the open end is composed of a plurality of powders through a cut groove (not shown) formed at a predetermined interval is a plurality of powder It can be configured to form an elastic force in the direction of pressing the outer peripheral surface of the inserted rope (14). In this case, the diameter of the opening is formed to be relatively smaller than the diameter of the rope, so that when the rope is inserted, a plurality of powders are spread outwards and then returned to their original positions by the elastic restoring force so as to elastically support the outer circumferential surface of the rope.

On the other hand, one end of the cap 41 is a hemisphere protruding, rotatably inserted into the cap groove 421 of the support 42 to be described later hemisphere protruding portion.

The support 42 is formed with a cap groove 421 into which the cap 41 is inserted, and the cap groove 421 is provided with a support ball groove 422 recessed inwardly.

Here, the cap groove 421 is inserted into the hemisphere protruding portion of the cap, the cap groove 421 is configured to have a hemispherical inner circumference to correspond to the shape of the cap, when the cap 41 is multi-directional The tilting is possible and the effect of minimizing the effects of vibration and shaking due to the stop inertia transmitted from the rope of the housing 22 coupled to the other end and the support 42 disposed in the opposite direction can be expected.

That is, the support 42 is coupled to the cap 41 is coupled to the rope connected to the ship on one side, the other end is coupled to the housing 22 is coupled to the cap coupled to the rope coupled with the depth measurement equipment, If any inclination occurs in either the ship or the depth surveying equipment, the stop inertia due to the arrangement arranged on the opposite side acts to return to the original position.

Of course, if the waves or currents applied to the ship or depth surveying equipment is strong, the ship or the depth surveying equipment can be inclined at the same time, the dust-proof means in the present invention minimizes the inclination when the depth surveying equipment is lifted by the rolling phenomenon This is to minimize the inclination caused by waves or currents of relatively small intensity.

On the other hand, the support shown in Figures 4 and 5 shows an embodiment in which the coupling groove 423 is opened toward the outside, the shape is wider toward the lower end for convenience when the housing is coupled, as another embodiment It may be formed to have the same diameter.
