Abstract

PURPOSE:To prevent a sea surface buoy from receiving a bad influence due to the waves by detecting noises near the sea surface, judging it that the waves are high when a fixed zone of the waves detected is higher than a predetermined level, and then winding a cable so as to lower the sea surface buoy into the sea. CONSTITUTION:A sea surface buoy 1, flotage buoy 2, echo sound receiver 3 and anchor 4 are connected in turn with a cable 5. In this case, the sea surface buoy 1 is provided with a winder 6 for winding the cable 5. The echo sound receiver 3 is connected to a receiver 7 with armored cables 11. Moreover, the receiver 7 is connected to a filter 8, level detector 9 and motor control 10, which are installed in the sea. A signal received with the echo sound receiver 3 is detected via the filter 8 with the level detector 9 for judging that the sea surface is rough when the results detected is greater than a predetermined level. Based upon the results, the winder 6 is driven in a winding direction by the motor control 10, thereby winding the cable 5 to lower the sea surface buoy 1 into the sea for preventing influence of the waves.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mooring buoy capable of floating and sinking a sea surface buoy.

[0002]

2. Description of the Related Art A mooring buoy is a device that captures sound waves on the sea floor and in the sea with a receiver and transmits a data signal to a receiving device on the ground or on the sea by a radio transmitter attached to the sea surface buoy. The related art will be described below with reference to the drawings. FIG. 5 is an explanatory diagram. In the figure, reference numeral 1 is a sea surface buoy, which incorporates a radio transmitter and the like. 2 is a buoyancy buoy, 3 is a wave receiver, and 4 is an anchor, all of which are sequentially connected by ropes 5. The mooring buoy thus constructed is fixed to the seabed by the anchor 4 and moored by the buoyancy buoy 2. The buoyancy of the buoyancy buoy 2 causes the wave receiver 3
Is fixed in the sea, sends signals of the sea bottom and the sea collected by the wave receiver 3 to the sea surface buoy 1, and transmits data to a ground or sea receiving device (not shown) by a radio transmitter of the sea surface buoy 1. According to such a mooring buoy, since the sea surface buoy 1 is floating on the sea surface, it is directly affected by tidal currents and wind and rain, and the sea surface buoy 1 is swept, moved up and down, and a great amount of tension is applied to the rope 5, Therefore, there is a problem that the rope 5 is cut off.

[0003]

The problem to be solved is that the ropes connecting the sea surface buoy to the buoyancy buoy are cut off and washed away due to tidal currents and wind and rain.

[0004]

According to the present invention, noise near the sea surface is detected by a receiver, a signal of only a certain band of the detected noise signal is selected by a filter, and the selected signal is selected. Avoid the influence of waves by detecting with a level detector to determine the roughness of the waves, and if it is determined that the waves are rough, wind the rope connected to the buoyancy buoy and lower the sea buoy into the sea. When the sea surface has subsided, the sea surface buoy will once again rise to the sea surface, and the accident that the rope is cut and washed away by the sea surface is eliminated.

An embodiment of the present invention will be described below with reference to the drawings. In the following description, the same parts as those in the above-mentioned conventional technique will be described using the same reference numerals. 1 is an explanatory view of main parts, FIG. 2 is a block diagram of main parts, FIG. 3 is an explanatory view of a state where a sea surface buoy is floating, and FIG. 4 is an explanatory view of a state where the sea surface buoy is submerged. It is a sea buoy and has a built-in wireless transmitter. 2 is a buoyancy buoy, 3 is a wave receiver, and 4 is an anchor, all of which are sequentially connected by ropes 5. A winder 6 is built in the sea surface buoy, and the end of the rope 5 is wound around the winder 6. Further, for example, the armored cable 1 is attached to the wave receiver 3.
1 and a receiver 7 connected by a slip ring,
Further, a filter 8, a level detector 9 and a motor control 10 are connected and built in the sea surface buoy 1, and this motor control 10 controls the rotation of the motor of the winder 6. According to the above configuration, the signal received by the receiver 3 is amplified to a certain level, and the correlation between the underwater noise and the ocean wave (“Ocean Acoustics” edited by Ocean Acoustics Research Group P96-97 and Nikkan Kogyo Shimbun) It is reported in detail in "Ultrasonic Technology Handbook", 4th edition, P630, etc., issued in January 1972.) Only a certain band in the band of 100HZ to 10KHZ is selectively passed by the filter 8. The passed signal is detected by the level detector 9, and if it is above a certain level, it is determined that the sea surface has large waves. When it is determined that the wave is large in this way, the motor control 10 operates the winder 6 in the winding direction to wind the rope 5 and lower the sea surface buoy 1 into the sea as shown in FIG. Not be affected by. The data of the seabed and the sea during this descent are stored in an internal memory, etc., and will be transmitted when the surface is resurfaced. on the other hand,
When it is determined that the waves are small and the sea surface buoy 1 is descending into the sea, the rope 5 is paid out from the winder 6 to float the sea surface buoy 1 on the sea surface and transmit it to the receiving device on the ground or sea. (Figure 3).

[0006]

According to the present invention described in detail above, the noise near the sea surface is detected by the wave receiver, and a signal of only a certain band of the detected noise signal is selected by the filter and selected. The signal is detected by the level detector to judge the roughness of the waves, and if it is judged that the waves are rough, the ropes connecting the sea buoy to the buoyancy buoys are wound up and the sea buoy is lowered into the sea, By allowing the impact to be avoided and allowing the sea buoy to rise again to the sea surface once the sea surface has subsided, the sea surface buoy is located in the sea when the waves are rough. It has the effect of eliminating the accident that the rope is severely shaken or swept away by the waves and the rope is cut off and washed away. In addition, the data while the sea buoy is descending into the sea is stored in the internal memory etc. and is sent when it resurfaces, and the bottom of the sea being descended into the sea and the data in the sea should also be accumulated. It has the effect that
