Description

Subsea mooring device for ocean current observation {SUBMARINE SURFACE MOORING APPARATUS FOR OCEANCURRENT OBSERVATION}

The present invention relates to an ocean floor mooring apparatus for ocean current observation, and more particularly, through a simple configuration, even if a portion of the ocean floor is lost due to uneven surface or current, the accurate flow rate and wave height of the current The present invention relates to an ocean floor mooring apparatus for ocean current observation that can sense, process, store, and transmit information.

Recently, as the modernization of fisheries and military applications, environmental monitoring and exploration activities are actively conducted, the unmanned apparatus for marine observation is widely researched and used to collect information on the marine environment. Moreover, in Korea, where the three sides are surrounded by the sea, the necessity is increasing.

Among the information on various marine environments, the information on the currents has a great influence on the climate and weather of the area to be measured, and helps in predicting and planning the catching and management of the fishes according to the movement of the fish. This current is a flow of seawater moving at a constant speed in a constant direction. When measuring information on the current, we want to know the direction and speed of the current.

In general, it is observed using current bottle, GEK (Geomagnetic Electro-Kinetograph), magnetic tachometer, laser tachometer, ultrasonic tachometer and satellite tracking buoy as a way to know the direction and velocity of the current.

In particular, a method using an ultrasonic tachometer is a method of observing the current through the Doppler effect of the sound waves reflected from the floating moving with the current at each depth by emitting sound waves. This method can be anchored to a place in the ocean or attached to a vessel and observed during operation. It can measure not only the direction and speed of the ocean current, but also the depth of the wave, ie the depth from the sea level to the bottom. When measuring currents using an ultrasonic tachograph, it can be attached to a vessel and observed during operation.However, for more accurate currents observation in a certain area, it can be settled and moored at the bottom of the sea area to be measured for information about current and crest for several days to several months. Observe.

So that they can be installed symmetrically about their centers. Main weight 200 is preferably to have a large mass in a small volume by using a high density material, such as a metal such as lead.

As shown in FIGS. 1 to 5, the supporting member 300 is formed in an annular shape and fixed to the upper portion of the frame 100. The supporting member 300 serves to rotatably support the gimbal mechanism 400 to be described later. When the frame 100 is in the shape of a pyramid, the support member 300 is fixed to the horn of the upper center of the frame 100.

The gimbal mechanism 400 is a two-axis rotating mechanism that operates so that the current current observation part 500 to be described later is always vertically standing with respect to the sea surface even when the frame 100 is tilted. The first rotating member 410 and the second It consists of a rotating member (420). 1, 2, 4 and 5, the first rotating member 410 is made in an annular shape is rotatably coupled back and forth inside the support member 300, the second rotating member 420 also It is manufactured in an annular shape and rotatably coupled to the inside of the first rotating member 410.

The support member 300, the first rotating member 410 and the second rotating member 420 may have a ring shape, that is, an annular shape, and may have any shape such as a square or a circle. However, it is enough to be inserted into the inside sequentially so that each can be rotated back and forth and left and right.

1 and 4, as shown in Figs. 1 and 4, the current center is fixedly coupled to the inner circumference of the second rotating member 420 so that the center of gravity is downward, and rotates together with the second rotating member 420. It also detects, processes, and stores information about flow rates and crests in currents. As a sensor for detecting information about the flow velocity and crest of the current, there are various types such as a sensor using light such as an ultrasonic wave or a laser.

At this time, by using the Doppler effect according to the launch and reception of the ultrasonic wave to detect the information on the flow rate of the current, it is to process and store the information in the CPU 521 built in the housing 520 to be described later. Based on this principle, the ultrasonic flowmeter 510 is also used for measuring the height from the sea bottom to the sea level, that is, the depth of the water. Since the function and action of the ultrasonic flowmeter 510 as described above can be implemented in the prior art, a detailed description thereof will be omitted.
