Description

Technical Field

[0001] The invention relates to the technical field of buoys, and in particular to a nearshore double-anchor current measurement buoy system. Background Art

[0002] At present, most buoy-based profile current observations at home and abroad use a single-point buoy mooring system. Most of them install current meters at the bottom of the buoy body, or hang current meters on the single-point mooring system to conduct profile current observations.

[0003] When the sea surface buoy is affected by wind, waves and currents, the buoy will pull the bottom mooring system to move. The greater the force of wind, waves and currents, the greater the inclination of the underwater mooring system. At this time, two problems will be encountered: First, the interaction between wind, waves and currents and the buoy will generate bubbles in the water around the buoy, which will affect the acoustic echo signal of the surface current meter (i.e. Doppler single-point current meter) or profiler (i.e. Acoustic Doppler Current Profiler ADCP) installed at the bottom of the buoy (manifested as poor quality of observation data obtained); second, the surface buoy is affected by the combined force of wind, waves and currents, resulting in excessive inclination of the mooring system, which affects the quality of instrument observation data (e.g., the data quality is very poor when the ADCP inclination exceeds 15 degrees), and thus makes the observation data unusable.

[0004] Therefore, there is an urgent need for a buoy mooring system that is safe and reliable, convenient for offshore operations, and can ideally observe nearshore currents or offshore currents. Summary of the invention

[0032] The present invention is further described in detail below through detailed embodiments in conjunction with the accompanying drawings.

[0033] Please refer to Figure 1 to Figure 5 The present embodiment provides a near-shore double-anchor current measurement buoy system, comprising two auxiliary buoys 2 and a main buoy 1 floating on the sea surface 100, wherein the two auxiliary buoys 2 are arranged in a straight line with the main buoy 1, and the main buoy 1 is located between the two auxiliary buoys 2, wherein one auxiliary buoy 2 is arranged close to the open sea, and the other auxiliary buoy 2 is arranged close to the shore; the two sides of the main buoy 1 are respectively connected to the two auxiliary buoys 2 through horizontal chains 3, and the two auxiliary buoys 2 are also respectively connected to main anchor systems 4, and the main anchor systems 4 are arranged toward a side away from the main buoy 1; the main buoy 1 is provided with a data acquisition control module 8, and a hanger 6 and a counterweight block 7 are connected below the main buoy 1 through a suspension cable 5, and the counterweight block 7 is located below the hanger 6, and a Doppler single-point current meter 81 and an acoustic Doppler current profiler 82 respectively connected to the data acquisition control module 8 are installed in the hanger 6. The Doppler single-point current meter can observe the currents on the surface of the water, and the acoustic Doppler current profiler can observe the currents in each layer of the seabed.

[0034] Auxiliary buoys and main anchor systems are respectively set up on both sides of the main buoy as a single-point buoy mooring system, and connected to the main buoy by a horizontal chain. Since they are towed and fixed in two directions, namely, toward the open sea and the land, the inclination of the combined force of wind, wave and current on the buoy mooring system can be decomposed. Such a distribution can minimize the force on the main buoy in the middle when hit by a typhoon, thereby minimizing the impact on the Doppler single-point current meter and the acoustic Doppler current profiler. At the same time, the main buoy is connected to the auxiliary buoy by a horizontal chain, which can avoid It avoids collision between auxiliary buoy and main buoy and entanglement between main anchor system and suspension cable, and provides sufficient underwater space for Doppler single-point current meter and acoustic Doppler current profiler under the main buoy to avoid interference and affect their normal work. Furthermore, the bracket suspended under the main buoy is in a free hanging state under the weight of the counterweight, so that the Doppler single-point current meter and acoustic Doppler current profiler installed on the bracket are not affected by the tension and inclination of the anchoring system, and are also free from the influence of bubbles, which greatly improves the quality of ocean current observation data.

[0035] In some specific embodiments, reference Figure 1 The main anchor system 4 includes an anchor body 41 and an anchor chain 42. The anchor body 41 is sunk to the seabed and connected to the seabed 200. One end of the anchor chain 42 is connected to the anchor body 41, and the other end of the anchor chain 42 is connected to the auxiliary buoy 2. Specifically, the anchor chain 42 includes a mooring chain 421 suspended in the seawater and a ground-lying chain 422 lying on the seabed 200. Through the cooperation of the anchor body and the ground-lying chain, the main buoy and the auxiliary buoy can be fixed on the sea surface more stably.

[0036] As an example, the anchor body 41 is a gripping anchor. The ground chain 422 can be a two-stage anchor chain with a step, which is more wear-resistant and has better tensile strength than ordinary anchor chains. Preferably, the length of the ground chain 422 is greater than or equal to twice the water depth, so as to ensure that the horizontal gripping teeth on the anchor body cut into the mud of the seabed.

[0037] As a preferred embodiment, the distance between the main buoy 1 and the auxiliary buoy 2 is greater than or equal to 40 m. In this way, it can be ensured that the brackets equipped with the Doppler single-point current meter and the acoustic Doppler current profiler under the main buoy are not entangled with the main anchor systems on both sides.

[0038] As an example, the suspension cable 5 may be a non-gear chain or rope, so as to facilitate the free suspension of the hanger.

[0039] In some specific embodiments, reference Figure 3The bracket 6 is a stainless steel frame 61 formed by welding and splicing a plurality of stainless steel rods. The upper and lower parts of the bracket 6 are provided with a suspension member 62. The suspension member 62 is provided with a mooring hole 621 connected to the suspension cable 5. The bracket 6 is also provided with a first mounting assembly 63 for fixing the Doppler single-point current meter 81 and a second mounting assembly 64 for fixing the acoustic Doppler current profiler 82. More specifically, the first mounting assembly 63 and the second mounting assembly 64 each include two C-shaped clamps 631, and the two ends of the C-shaped clamp 631 are provided with a fixing plate 632 welded to the stainless steel frame 61. Through the enclosure of the two C-shaped clamps, the Doppler single-point current meter or the acoustic Doppler current profiler can be installed and fixed.

[0040] As an improved implementation, Figure 3 As shown, the rack 6 is also provided with a zinc anode 65, so as to prevent the rack from being corroded by seawater and to protect the rack well.

[0041] As an example, the distance from the hanger 6 to the sea surface 100 can be set to 5m, the distance from the counterweight 7 to the sea surface 100 can be set to 10m, and the Doppler single-point current meter 81 is arranged above the acoustic Doppler current profiler 82. Such an arrangement is the best arrangement position and has a better observation effect.

[0042] In some specific embodiments, reference Figure 2 The two sides of the main buoy 1 are provided with connecting plates 11, and the connecting plates 11 are provided with assembly holes 111 connected to the horizontal chain 3. In this way, the horizontal chain is connected to the side of the main buoy, which can further prevent the inclination of the mooring system from affecting the work of the Doppler single-point current meter or acoustic Doppler current profiler under the main buoy. Figure 4 and Figure 5 The horizontal chain 3, auxiliary buoy 2 and main anchor system 4 located on the same side are connected by a hanging plate 9. The hanging plate 9 is a three-hole metal plate with three connecting holes 91 in the shape of an equilateral triangle. The first connecting hole of the hanging plate 9 is connected to the bottom of the auxiliary buoy 2, the second connecting hole of the hanging plate 9 is connected to the end of the horizontal chain 3 away from the main buoy 1, and the third connecting hole of the hanging plate 9 is connected to the end of the main anchor system 4 away from the seabed. By setting a special hanging plate, the horizontal chain, auxiliary buoy and main anchor system can be freely connected, which is convenient for offshore deployment and recovery.

[0043] In some specific embodiments, reference Figure 2The main buoy 1 includes a main buoy body 12 and a mast 13. The lower part of the mast 13 is connected to the top of the main buoy body 12. The mast 13 and / or the main buoy body 12 are equipped with a solar panel 83 for power supply. The solar panel 83 is connected to the data acquisition control module 8. A through well 14 for hanging a counterweight block 7 and a hanger 6 is provided in the middle of the main buoy body 12. A meteorological platform 15 is also provided on the upper part of the mast 13. As an example, the meteorological platform 15 is equipped with meteorological monitoring equipment, navigation lights, antennas and other equipment. The meteorological monitoring equipment includes an anemometer, a temperature and humidity meter, a barometer, etc. The antenna includes a Beidou positioning / data transmission instrument, etc. The outer periphery of the main buoy body 12 is provided with an instrument well, which is used to install conventional underwater monitoring equipment. In this way, the main buoy has platform functions such as data acquisition, energy supply, signal transmission, and operation carrier.

[0044] In some specific embodiments, reference Figure 4 The auxiliary buoy 2 includes an auxiliary buoy body 21 and a navigation light 22, and the navigation light 22 is fixed to the top of the auxiliary buoy body 21 through a support rod 23. The support rod 23 on the auxiliary buoy 2 is also equipped with a radar transmitter for real-time monitoring of the surrounding situation.

[0045] When deploying at sea, Figure 1 As shown, an auxiliary buoy 2 may be deployed first on the side close to the land direction B, then the main buoy 1 may be deployed, and finally another auxiliary buoy 2 may be deployed on the side close to the open sea direction A. The whole process is relatively simple to operate.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
