Description

BUOY FOR DETECTING RIP CURRENT}

The present invention relates to a buoy for language observation, and more particularly, has a size suitable for installation in the crushing band, and is designed to exclude the influence of wind and crushing wave within the crushing band and to move according to the flow of langues The present invention relates to a buoy for observing languages so that the flow of languages can be understood.

When a wave is pushed to the beach from a long distance, the water does not move at a depth 1.5 times deeper than digging, but only the energy that causes the wave. However, when waves approach the beach and approach or break into the wreckage, they lose their inherent waveform and the waves are broken, and not only the form of the waves is transmitted but also the actual seawater is pushed to the beach.

The mass transport of seawater generated by this generation mechanism increases as the size of the wave increases, and when water enters the beach over the entire beach, a large amount of water must escape somewhere. The accumulated water forms a narrow, strong stream, and flows from the coastline toward the open sea. It is called rip current. In general, lans are narrow and have high flow rates (2–3 knots), which can cause drowning beaches.

Ilans are determined by the shape of the seabed and the shape of the shoreline, which is known to form in long coastal regions where tears are parallel or nearly parallel to the shoreline. However, the water that escapes due to the formation of languae is swept away by the sand in the sea to form a deep puddle or waterway. People who have entered are often swept away by Ian-ryu.

Therefore, it is important to know the flow of languae and to know and prepare the location of languages. To this end, the buoy should be installed to observe the flow and characteristics of the languae. The buoys, which have been used in the past, are equipped with wings to ride the flow well. There is a problem that can not ride on the shore and ride on the shore, the size is too large, there is a problem having an inappropriate size to be installed on the shore where the breaking wave is formed.

The present invention has been made to solve the above-mentioned problems, as a dedicated buoy for observing the iris and has a size suitable for installation in the crushing band where the iris occurs, and is less pushed by the wind and crushing wave The purpose is to provide buoys for observing the iris flow, which can be mainly influenced by the flow of iris to understand the flow of iris flow.

In order to achieve the above object, the buoy for binocular observation according to the present invention is a cylindrical lower body portion having an isolated inner space, a mass body coupled to the lower end of the lower body portion, and coupled to and separated from the upper end of the lower body portion It characterized in that it comprises an upper body portion having a cross-sectional area smaller than the cross-sectional area of the main body portion, and a position tracking device for coupling to the inner space of the upper body portion. Here, on the sea level, the lower body portion is located below the water surface, and the upper body portion is floated to be exposed above the water surface.

In addition, it is preferable that the height of the lower body portion is 30 to 40 cm, the height of the upper body portion is designed to 10 ~ 20 cm to move along the flow of superior languae formed near the sea surface.

In addition, the position tracking device is a precision satellite positioning system (DGPS: Differential Global Positioning System) to correct the position error of the existing satellite positioning system to enable more accurate position measurement.

According to the buoy for binocular observation according to the present invention, by having a cylindrical lower main body portion and a cross-sectional area smaller than the cross-sectional area of the lower main body beam and having an upper main body exposed on the sea surface, it is pushed less by the influence of wind or breaking waves. It is advantageous to provide a dedicated buoy for observing the iris flow to prevent the flow, and to be mainly influenced by the flow of iris flow to grasp the flow of the iris flow. The actual observation follows a cyclical flow in the wreckage band due to the occurrence of iris flow.

In addition, the lower body portion and the upper body portion has a height of 30 ~ 40 cm, 10 ~ 20 cm, respectively, has a size that is suitable for installation in the crushing band where iris flow occurs, 1/4 of the total depth within the crushing band It is to be able to observe superior languages observed within.

In addition, it is desirable to enable the precise positioning of the positional error having a position error of about 1 to 3 m using the DGPS, so that the characteristics of the binoculars can be well understood.

FIG. 1 is a view schematically illustrating a buoy for binocular observation according to an embodiment of the present invention.
FIG. 2 is a view illustrating a buoy for buoyancy observation according to the embodiment of FIG. 1 floating on the sea surface.

Hereinafter, with reference to the accompanying drawings, the buoy 100 for iris observation according to an embodiment of the present invention will be described in detail.

1 is a view schematically showing a buoy 100 for yiangryu observation according to an embodiment of the present invention, Figure 2 is a buoy 100 for yiangryu observation according to the embodiment of Figure 1 floating on the sea surface Figure is a diagram.

1 to 2, the buoy 100 for observing the ocular flow according to the present exemplary embodiment includes a lower main body 110 and an upper main body 120.

The lower body 110 has an isolated internal space, the air or other gas is injected into the internal space. The buoyancy observing buoy 100 for floating in the sea surface by the received buoyancy determined by the volume occupied by the lower main body 110 in the water. The inner space is isolated from the outer seawater, preventing the seawater from entering the inner space.

The lower body portion 110 has a cylindrical shape of a horizontal cross section is circular. When the lower main body 110 has a cylindrical shape, the floating body on the sea surface is not deflected further and flows in a specific direction, and may be affected evenly in any direction of the buoy 100 for the binocular observation. Make sure the movement reflects the flow of languages.

Mass body 111 is coupled to the lower end of the lower body portion 110. The mass 111 may be installed outside the lower body portion 110, or may be installed in the inner space of the lower body portion 110 as shown in FIG. When the buoy 100 for ionic flow observation is floating on the sea surface by adjusting the mass of the mass 111, the lower body portion 110 is located below the sea level, and the upper body portion 120 to be described below is exposed above the sea level. Be sure to As a result, the position tracking device 121 to be described later, which is installed in the inner space of the upper main body 120, is exposed to the water so that transmission and reception of signals can be performed smoothly.

In addition, the mass body 111 is coupled to the lower end of the lower body portion 110 to allow the oyster flow observation buoy 100 to stably stand up in the water. Since the mass body 111 is coupled to the lower end of the lower body portion 110, when the buoy 100 for ionic flow observation floats on the sea surface, the lower portion of the lower body portion 110 to which the heavy body weight 111 is coupled is downward. When the upper body portion 120, which will be described later, is positioned upwards, the buoyancy observation buoy 100 is upright in the vertical direction, and falls or is turned upside down even when it is shaken by wave pressure while moving along the flow of the binocular. To maintain your original upright position.

The upper body portion 120 is coupled to the upper end of the lower body portion 110, has an isolated internal space, and has a horizontal cross-sectional area smaller than the horizontal cross-sectional area of the lower body portion 110.

The location tracking device 121 is installed in the internal space of the upper main body 120, and the internal space is isolated from the outside to prevent the location tracking device 121 from being damaged by the inflow of seawater.

The upper body portion 120 is formed to have a cross-sectional area smaller than the cross-sectional area of the lower body portion 110. The mass body 111 is coupled to the lower end of the lower body portion 110, the upper body portion 120 is located on the upper side, the upper body portion 120 is exposed to the sea level by adjusting the weight of the mass body 111, the upper body The portion 120 is formed to have a small cross-sectional area so that the portion exposed to the sea level is less. As a result, the buoy 100 for observing the iris flow may be prevented from being moved by the wind, and the movement may be mainly influenced only by the flow of iris flow.

The location tracking device 121 may be a satellite positioning system (GPS), a network assisted GPS (A-GPS), a real-time location tracking system (RTLS), and the like, but the error information of the existing satellite positioning system may be used. It is desirable to use a Differential Global Positioning System (DGPS) that can be calibrated to enable more accurate positioning.

The position tracking device 121 is a precise clock using an antenna, a crystal oscillator, etc. tuned to a frequency transmitted from a GPS satellite, a processing device for processing a received signal, calculating coordinates and velocity vectors of a receiver position, and calculated results. It includes a GPS receiver that additionally includes a communication port, such as RS-232, for transmission and reception of observation results between the output device and the other receiver.

Here, the height (H) of the lower body portion 110 is 30 to 40 cm, the height (h) of the upper body portion 120 is preferably 10 to 20 cm. In general, the rupture band in which irises are formed is formed at a depth lower than a person's height, and the superior irises can be observed at a depth within a quarter of the total depth. Therefore, by setting the height of the lower body portion 110 and the upper body portion 120 as described above can be well influenced by the flow of the superior eye flow at the same time having an appropriate size to be installed in the crushing band observed the irises. There is an advantage that can obtain the buoy 100 for language observation.

In addition, the lower body portion 110 and the upper body portion 120 has a lower opening and closing device 130 and the upper opening and closing device 140, respectively, the inner space and the upper body portion (the lower body portion 110) ( It allows access to the internal space of 120). This can be made to easily manufacture and repair the buoy 100 for language observation.

Hereinafter, with reference to the accompanying drawings the operation of the buoy 100 for observing binocular according to the present embodiment.

Referring to FIG. 2, the buoy 100 for binocular observation according to the present embodiment is floated such that the lower main body 110 is below the sea level, and the upper main body 120 is exposed above the sea level. Buoy 100 for iris flow observation according to the present invention is floating in the depth range of the flow of the iris flow is well observed and moves under the influence of the flow of iris flow. The movement of the buoy 100 is transmitted from at least three satellites and analyzed from a signal received by the DGPS installed in the upper main body 120 to obtain position information of the buoy 100. In the case of DGPS The position of the buoy 100 can be measured with an accuracy of 1 to 3 m.

At this time, the buoy 100 for observing the iris flow has an advantage that can be prevented from moving in the wind direction under the influence of the wind because there is little exposed portion above the sea surface. In addition, as described above, since the flow of the binocular flows in the well-determined depth range, it can also be prevented from moving under the influence of the breaking wave formed in the breaking band. Therefore, there is an advantage that a dedicated buoy for observing the binocular flow, which is able to grasp the flow of the binocular flow by moving mainly by the flow of the binocular flow, not by the wind or the breaking wave, is provided.
