1 to 6, an ocean buoy according to an embodiment of the present invention includes a table 10 and a surface 10 which is expressed on the surface of the water; Floating body 20 in contact with the water; It may include; a back pain 30 is locked down the surface of the water.

The body 10 is a part that is exposed to the surface of the buoys collectively, the upper port is formed in a cylindrical shape and the starboard is formed in a conical shape of the starboard is formed on the upper side of the upper table 110 of the buoy It includes a lighting device 120 to visually display the presence, the inside of the body 10, the radar reflector 130 is built in the outside so that the position of the buoy by the night light such as a ship can be detected. Retroreflective material 140 is attached, one side of the body 10 may be attached to the lifting ring 150 for the lifting operation of the buoy. The material of the body 10 is made of high density polyethylene (HDPE, High Density Polyethylene) as the material of the entire marine buoy according to the present invention, the inside is filled with a foaming resin. In particular, due to the characteristics of the surface 10 exposed over the surface of the surface 10 may be applied by mixing a separate UV protective material to prevent discoloration.

The double table 110 is a portion forming the upper end of the surface 10, the port as shown in (1) of Figure 2 is formed in a cylindrical shape, as shown in (2) of Figure 2 starboard It will be formed into a conical shape (more specifically, a truncated cone shape).

The lighting device 120 is a component installed to visually display the presence of the buoy on the upper side of the two table 110, the type of lighting device in particular as long as it generates a light to be recognized by an external vessel. Although not limited thereto, LED lighting devices may be preferably used.

The radar reflector 130 is attached to the inside of the body 10 to be detected by the radar in a 360 degree direction, a plurality of reflectors (reflectors) formed of aluminum or stainless material to increase the laser detection rate It can be formed by continuously attaching in the form of a cluster (cluster) along the circumference of the inner peripheral surface.

The retro-reflective material 140 is attached to the outer circumferential surface of the body 10 so that the position of the buoy can be detected by a night light such as a ship, and formed of a metal material having a high reflectance by the illumination light. It is preferable to be attached and formed at regular intervals along the circumference.

The lifting ring 150 is configured to be attached to the outer peripheral surface of the body 10 to facilitate the lifting operation during installation and collection of the marine buoy according to the present invention, it can increase the durability in the installation and collection process It is usually made of galvanized carbon steel that can withstand tensile strength of 7 tons or more, so that it can maintain strength and prevent corrosion. The lifting ring 150-1 is generally attached to the outer circumferential surface of the head 110, but if necessary, the lifting ring 150-2 is further added to the boundary between the surface 10 and the floating body 20. Can be attached.

The floating body 20 refers to a part that comes into contact with the water surface in the buoy, and as shown in FIG. 1, the floating body 20 may improve the buoyancy and balance (stability) as described below. It is preferable to have a diameter larger than the diameter of the back barrel 30, and the material of the floating body 20 is also formed of high density polyethylene (HDPE, High Density Polyethylene) in the same manner as the material of the entire marine buoy according to the present invention. The buoy is allowed to float without being submerged even when a part of the high density polyethylene (HDPE) is damaged due to the filling of the foamed resin and the collision with the ship.

The thong 30 refers to a part that is submerged below the surface of the buoy, in particular in the present invention, the overall shape of the thong 30 portion is larger in diameter at the connecting portion of the floating body 20 and the thong 30 It is formed in a truncated conical shape which is inclined while being reduced to a small diameter thong 30 in the floating body 20, and is formed in a conical shape at the distal end of the trough 30, reducing the vertical resistance of the buoys, such as blue Buoys easily enter the water to change the sea level is characterized in that it can prevent the breaking of the mooring ring 320 or mooring rope 50 to be described later. That is, as pointed out in the problems of the prior art, conventional buoys generally have a lower cross section of the buoy which is flat, and in the vertical direction from the bottom of the buoy to the bottom of the water surface when a momentary sea level change occurs due to blue or the like. Since the vertical resistance generated increases, even if the sea level rises momentarily, the buoy does not easily enter the water accordingly, the vertical resistance is added to the existing buoyancy, and the level of the buoy increases instantaneously based on the sea floor, thereby fixing the buoy. When the mooring rope 50 and the mooring ring 320 to which the mooring rope 50 is fixedly coupled are transmitted with great tension, the mooring rope 50 or the mooring ring 320 is broken or worn or even fixed to the seabed. Bars will cause a problem to be broken up to 60, in the present invention to solve the above problems the back pain (30) As shown in FIG. 6, the connection portion between the floating body 20 and the back barrel 30 is formed in a truncated cone shape which is inclined while being reduced in diameter from the large body 20 to the small diameter barrel 30. It is formed in a conical shape at the distal end of the (30), so that the flow of the sea surface which is instantaneously rising by the blue, etc. can be smoothly guided upward without interfering with the lower end of the back barrel (30) to rise from the bottom of the back barrel (30) By reducing the vertical resistance generated in the vertical direction against the flow of the sea level, buoys easily enter the water even at the moment of sea level change, so that the level of the buoy is kept constant relative to the sea floor. It is possible to effectively prevent the breakage or wear of the ring 320 or the needle 60.

Mooring that can adjust the engaging position to the rudder 310 protruding in the form of a plate on one side of the back barrel 30 and the mooring hole 311 formed at regular intervals along the longitudinal direction of the rudder 310 The ring 320 may include a weight 330 attached to the lower end of the thong 30 so that the center of gravity of the buoy is located below.

The rudder 310 is a part formed to protrude in a vertical direction in a plate shape from one side of the back barrel 30, and uniformly distributes the flow of water to the left and right sides of the buoy to minimize the rotation or shaking of the buoy. That is, since the rudder 310 is formed on one side of the backache 30 positioned below the surface of the water as shown in FIG. Since it is possible to distribute evenly in the left and right directions, buoy according to the present invention is not rotated or shaken innumerably unlike the prior art, so that the mooring rope 50 or the like connected to the mooring ring 320 will be twisted or wound. It can also be prevented.

In the longitudinal direction of the rudder 310 may be formed a plurality of mooring holes 311 formed at a predetermined interval along the longitudinal direction, as shown in Figure 5, which will be described later coupled to the mooring hole 311 To adjust the position of the mooring ring 320. In order to keep the buoy in balance despite rapid water flow, the point where the mooring rope 50 is fixed to the buoy, that is, the position of the mooring ring 320 is important. As the external force to the flow rate, or resistance, is proportional to the cross-sectional area in contact with the flow of water,

F _a = 1/2 * ρ _a * C _p * A _a * V _a ²

(F _a : external force acting on the structure (velocity), ρ _a (density): seawater density to air density, C _p (drag coefficient): 0.5 ~ 2.0 (generally 1.0 applied, depending on the shape of the member), A _a (projection area): projected area of the externally loaded member (㎡), V _a (velocity): relative speed with respect to the externally loaded member (m / s))

As shown in FIG. 5, the cross-sectional area A1 of the upper part of the mooring ring 320 and the lower cross-sectional area A2 of the mooring ring 320 are the same at the point where the mooring rope 50 is coupled to the buoy, that is, the position of the mooring ring 320. The buoy can then remain balanced despite the flow rate. That is, when the cross-sectional area A1 of the upper side of the mooring ring 320 is larger than the cross-sectional area A2 of the lower side, the buoy is inclined in the direction B1 due to the flow rate, and on the contrary, the cross-sectional area A2 of the lower side of the mooring ring 320 is upward. If it is larger than the cross-sectional area A1, the buoy is inclined in the B2 direction due to the flow rate, so the position of the mooring ring 320 is preferably located at the point A1 = A2 where the upper and lower cross-sectional areas are equal, and accordingly, in the present invention, the rudder By using the mooring hole 311 formed in a plurality at regular intervals along the longitudinal direction of the 310 it is possible to adjust the coupling position of the mooring ring 320 as needed.

The mooring ring 320 is coupled to the mooring hole 311 formed along the longitudinal direction of the rudder 310 to allow the mooring rope 50 for fixing the buoy to be coupled and fixed, such as in Figure 5 As shown, a through hole is formed on one side of the mooring ring 320 so as to be coupled to the mooring hole 311, and the other side of the mooring rope 50 is coupled and fixed. Can be formed.

The weight 330 is configured to be attached to the lower end of the thong 30 so that the center of gravity of the buoy is located below, for this purpose, the weight 330 may be a metal member of several kilograms to several tens of kilograms. . Due to the characteristics of buoys floating above sea level, it is important to minimize the fluctuations caused by waves or waves caused by waves or waves. For this purpose, the center of gravity of buoys is at the lower end of buoy, that is, at the lower end of thong 30. To increase the resiliency of the buoy. Therefore, in the present invention, by including the weight 330 inside the lower end of the thong 30, the center of gravity of the buoy to the bottom and the portion of the submerged in the water by increasing the resilience of the buoy to increase the resilience of the buoys or waves Even if the sea level fluctuates, the buoy will not be shaken, so that the position can be stably held.

7 to 9, the marine buoy according to another embodiment of the present invention is connected to the observation device 70 is installed on the seabed and the communication cable 80, both ends are fixed to the invasion 60 fixed to the seabed And mooring ropes 50 connected to the mooring ring 320 of the marine buoy to moor and fix the marine buoy within a predetermined range; Auxiliary floating device (40) connected to the mooring rope (50) to move on the mooring rope (50) in accordance with the flow of water, to prevent the loose mooring rope (50) in the opposite direction of the flow of water to the buoy; It may include.

In the ocean, the observation device 70 is installed on the sea floor for observation of marine data mainly in areas where the external force such as wind, blue, and tidal current is severe, and at this time, the position where the observation device 70 is installed is displayed. In order to be able to transmit data from the observation device 70 to install the buoy according to the invention. That is, the marine buoy according to the present invention indicates the location where the observation device 70 is installed by being connected to the observation device 70 and the communication cable 80 installed on the seabed as well as the communication cable (from the observation device 70). The data transmitted through 80) is retransmitted using the communication module.

As described above, the mooring rope 50 is configured to fix the buoy so that the marine buoy floating on the water surface can be fixed within a predetermined range, and both ends of the mooring rope 50 are undersea rock. It is connected to the needle 60, which is fixed to the back and is firmly fixed, the middle portion of the mooring rope 50 is coupled to, and fixed to the mooring ring 320 of the marine buoy according to the present invention. At this time, the mooring rope (50) is formed in a certain length of the allowance rather than a straight line between the buoy and the pendulum (60), which is so that buoys do not deviate from a certain range while mooring a portion according to the flow of water. This is to fix the momentary tension acting on the mooring rope 50 in the case of sudden sea level fluctuation due to waves or the like. However, as the mooring rope 50 is formed to have a predetermined length as described above, the mooring rope 50 may be wound or twisted to a buoy or the communication cable 80. In order to prevent the additional auxiliary floating device 40 may be further included.

The auxiliary floating device (40) is connected to the mooring rope (50) while moving on the mooring rope (50) in accordance with the flow of water, the loose mooring rope (50) in the opposite direction of the flow of water buoy or communication cable (80) In this configuration, the auxiliary floating device 40 has a support rod 410 having a predetermined length and a connection to allow the mooring rope 50 to pass and be connected at both ends of the support rod 410. The ring 420 and the support rod 410 may include a buoy 430 that provides buoyancy so that the auxiliary floating device 40 can rise above the water surface.

The support rod 410 is formed in the shape of a rod having a predetermined length (usually about 2m or so) as a portion constituting the skeleton of the auxiliary floating device 40. Since the support rod 410 is formed in a rod shape having a predetermined length, the mooring rope 50 connected along the longitudinal direction of the support rod 410 is prevented from being wound around the buoy body or twisted with the communication cable.

The connecting ring 420 is configured to form an annular shape so that the mooring rope 50 passes and is connected at both ends of the support bar 410, and the mooring rope 50 is formed at both ends of the support bar 410, respectively. By sequentially connecting the connecting ring 420 is connected to the auxiliary floating device 40 along the longitudinal direction of the support rod 410.

The buoy 430 is connected to the support rod 410 to provide a buoyancy force so that the auxiliary floating device 40 can rise above the water surface, and the support rod is generally the same as the position where the connection ring 420 is formed. It is preferable to be formed at both ends of the 410, the buoy 430 is to provide a buoyancy to be floated, as well as the auxiliary floating device 40, the mooring rope 50 connected thereto, such as a foam resin It can be formed as.

Hereinafter, referring to FIGS. 8 and 9, the operation and function of the auxiliary floating device 40 according to the flow of water will be described.

First, as shown in FIG. 8, when water flows in one direction (① direction), the buoy also moves within a predetermined range in the ① direction according to the flow direction of the water, and thus the mooring rope 50 fixing the buoy accordingly. The water flow direction side becomes taut and the water flow direction side becomes loose. At this time, the auxiliary floating device 40 connected to the mooring rope 50 is also moved in the ① direction, especially around the mooring ring 320 (part of the mooring rope 50 is coupled to the buoy) of the buoy. The connecting ring 420 of one end of the support rod 410 is the left side of the mooring ring 320, the connecting ring 420 of the other end of the support rod 410 is mooring rope 50 and the right side of the mooring ring 320, respectively. It is important to ensure that the auxiliary floating device 40 is always located around the buoy while being limited by the length of the support rod 410 by moving the auxiliary floating device 40 by the connection. Accordingly, the mouth 430 located on the side of the mooring rope 50, which is located in the direction opposite to the flow of water around the mooring ring 320, sleeps the support rod 410 and the (loose) mooring rope 50. The mooring rope 50, which is loosened by rising, can be effectively prevented from being wound or twisted with the buoy or the communication cable 80.

On the contrary, when water flows in the other direction (② direction) as shown in FIG. 9, the buoy also moves within a predetermined range in the ② direction according to the flow direction of the water, and thus the mooring rope 50 fixing the buoy accordingly. ), The flow direction of the water becomes taut and the opposite side of the flow of water becomes loose, and the auxiliary floating device 40 connected to the mooring rope 50 also moves in the direction of ②, while the mooring ring 320 of the water Float 430 located on the side of the loosely laid mooring rope 50 on the opposite side of the flow floats the support rod 410 and the (loose) mooring rope 50 to the surface, thereby loosening the mooring rope 50.
