Description

Technical Field

[0001] The invention belongs to the technical field of ocean observation buoys, and in particular relates to a novel three-anchor large ocean observation buoy capable of resisting severe typhoon sea conditions. Background Art

[0002] In the long-term development of marine science research, the long-sequence, continuous and real-time acquisition of ocean profile observation data has become a key bottleneck for this discipline to achieve original results. In order to solve the technical problems related to the real-time observation of ocean water profiles, many attempts have been made in the relevant technical fields at home and abroad in terms of sensor technology, communication transmission technology, system structure design technology, mooring technology and energy supply technology, which have greatly improved the system design and equipment development level related to water profile observation, and played an important supporting role in the development of marine science and marine engineering. At present, the acquisition of a large amount of marine environmental data faces the dilemma of having to rely on large scientific research ships.

[0003] Large ocean buoys can solve the problem that the acquisition of marine environmental data must rely on large scientific research vessels. However, most large ocean buoys are moored in a single anchor manner and are not equipped with auxiliary buoys. Under the single anchor mooring method, the surface mark is prone to free rotation under the action of the marine environmental load. The mooring system has obvious wave-following effects and a larger range of activities. When conducting uninterrupted observations of the marine environment, data is prone to deviations. When conducting hydrological and meteorological observations, the anchor system is very likely to get entangled with the seabed-based cables. At the same time, in the process of conducting marine hydrological and meteorological observations in the near sea, the severe sea conditions with frequent typhoons along the coast, frequent ecological disasters in the near sea, and the disorderly fishing of fishermen in the near sea have brought many difficulties to the observation of the near-shore marine environment. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a new type of three-anchor large ocean observation buoy that can withstand the severe sea conditions of typhoons.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A new type of three-anchor large ocean observation buoy capable of withstanding severe sea conditions caused by typhoons, comprising an ocean hydrological and meteorological observation buoy, a buoy for pulling the ocean hydrological and meteorological observation buoy, and an anchoring assembly for pulling the buoy, wherein a pulling steel rope is arranged between the ocean hydrological and meteorological observation buoy and the buoy; three groups of buoys and anchoring assemblies are arranged, and the three buoys are evenly distributed circumferentially on the outside of the ocean hydrological and meteorological observation buoy; the anchoring assembly comprises a torpedo anchor fixed on the seabed, a fixed pulley fixed on the upper part of the torpedo anchor, and a mooring cable for pulling the buoy.

[0007] In the above technical solution, further, the free end of the mooring cable passes around the fixed pulley and is fixed with a pulling buoy.

[0008] Furthermore, a volume adjusting member is provided inside the pulling float.

[0009] Furthermore, the volume adjusting part includes an inner steel pipe welded to the inner surface of the pulling float, a limiting tube welded to the upper part of the pulling float, a rotating rod arranged in the limiting tube, a screw arranged at the lower part of the rotating rod, a push plate arranged in the inner steel pipe, and a sealing gasket sleeved on the outside of the push plate for sealing; a water inlet hole is provided at the lower part of the pulling float, and the water inlet hole is located at the bottom of the inner steel pipe; the top of the rotating rod is located outside the float; a screw hole is opened at the top of the inner steel pipe, and the screw is fixedly connected to the push plate after passing through the screw hole, and the sealing gasket is tightly against the inner surface of the inner steel pipe.

[0010] Furthermore, a sealing rubber ring is installed in the groove formed on the inner surface of the limiting tube, and the sealing rubber ring contacts the outer surface of the rotating rod.

[0011] Furthermore, a limiting clamping plate is integrally formed on the outer surface of the push plate, a limiting clamping groove is provided on the inner surface of the sealing gasket, and the limiting clamping plate is installed inside the limiting clamping groove.

[0012] Furthermore, the mooring cable is fixed to the center position of the lower end of the buoy.

[0013] Furthermore, the angle between the mooring cable between the pulling buoy and the torpedo anchor and the vertical direction is 60°, and the lower part of the fixed pulley is provided with an anti-slip structure for limiting the mooring cable.

[0014] The present invention is beneficial in that:

[0015] The present invention limits the position of the ocean hydrological and meteorological observation buoy by means of three buoys and a novel anchoring foundation, thereby increasing the stability of the ocean hydrological and meteorological observation buoy placed in the ocean, while avoiding the phenomenon that the traditional ocean hydrological and meteorological observation buoy is easily affected by the impact of ocean waves and currents and causes the anchor to be dragged when a single anchor is used for fixation; further, by limiting the range of movement of the ocean hydrological and meteorological observation buoy, it is convenient to observe fixed points in the ocean and ensure the accuracy of the data; at the same time, it prevents the single anchor fixation from causing entanglement with the seabed cable, thereby improving the safety of the fixation of the ocean hydrological and meteorological observation buoy; the buoy and the ocean hydrological and meteorological observation buoy are connected by a pulling steel rope, which facilitates the positioning of the ocean hydrological and meteorological observation buoy through the buoy and the three groups of anchoring components; when severe sea conditions occur, the ocean hydrological and meteorological observation buoy moves with the buoy by pulling the steel rope, and at the same time, the buoy drives the mooring cable to move, which can effectively reduce the impact of the severe sea conditions on the ocean hydrological and meteorological observation buoy.

[0016] The volume adjustment member provided in the pulling float can facilitate the adjustment of the buoyancy of the pulling float, and facilitates the adjustment of the buoyancy of the pulling float during installation of the ocean float, so that the buoyancy of the pulling float can be adjusted according to the deadweight of the ocean hydrological and meteorological observation buoy.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figure 1 and Figure 3 , Figure 4 , Figure 5 The present invention provides a technical solution as follows:

[0027] A three-anchor fixed large ocean buoy comprises an ocean hydrological and meteorological observation buoy 1, a buoy 2 for pulling the ocean hydrological and meteorological observation buoy 1 and an anchoring assembly for pulling the buoy 2, a pulling steel rope 3 is fixed between the ocean hydrological and meteorological observation buoy 1 and the buoy 2; three buoys 2 and three anchoring assemblies are provided, and the three buoys 2 are evenly distributed on the outside of the ocean hydrological and meteorological observation buoy 1 at equal intervals; the anchoring assembly is provided with a torpedo anchor 4 for fixing to the bottom of the ocean, a fixed pulley 6 fixed to the upper part of the torpedo anchor 4, and a mooring cable 5 for pulling the buoy 2, and the free end of the mooring cable 5 passes around the fixed pulley 6 and is fixed with a pulling buoy 7.

[0028] The three anchoring components and the three buoys 2 are used to limit the position of the marine hydrological and meteorological observation buoy 1, thereby increasing the stability of the marine hydrological and meteorological observation buoy 1 placed in the ocean, while avoiding the problem that the traditional marine hydrological and meteorological observation buoy 1 is fixed by a single anchor, which causes the marine hydrological and meteorological observation buoy 1 to be easily affected by ocean waves and currents and cause deflection. The deflected marine hydrological and meteorological observation buoy 1 will increase the range of activities. The marine hydrological and meteorological observation buoy 1 with a small range of activities is convenient for observing fixed points in the ocean, thereby ensuring the accuracy of the data, while preventing the single anchor fixation from causing entanglement with the seabed cable, and improving the safety of the fixation of the marine hydrological and meteorological observation buoy 1. The anchoring component includes a torpedo anchor 4, a mooring cable 5, and a fixed pulley 6, and the buoy 2 is pulled by the mooring cable 5. The free end of the mooring cable 5 bypasses the fixed pulley 6 and is fixed to the pulling buoy 7, so that the pulling buoy 7 can pull the buoy 2 by relying on the buoyancy of seawater. The buoy 2 and the ocean hydrological and meteorological observation buoy 1 are connected by a pulling steel rope 3, so that the ocean hydrological and meteorological observation buoy 1 can be positioned by the buoy 2 and three groups of anchoring components.

[0029] See also Figure 1 and Figure 2 The pulling float 7 is provided with a volume adjusting member, which includes an inner steel pipe 8 welded on the inner surface of the pulling float 7, a water inlet hole 9 provided at the lower part of the pulling float 7, a stopper tube 10 welded at the upper part of the pulling float 7, a screw rod 13 provided at the lower part of the rotating rod 11, and a sealing gasket 15 for sealing provided on the outer surface of the push plate 14. The water inlet hole 9 is located at the bottom of the inner steel pipe 8, the rotating rod 11 is installed in the stopper tube 10, the screw rod 13 is rotatably connected to the push plate 14 installed in the inner steel pipe 8, the sealing gasket 15 is in close contact with the inner surface of the inner steel pipe 8, a sealing rubber ring 12 is installed in the groove provided on the inner surface of the stopper tube 10, and the sealing rubber ring 12 is in contact with the outer surface of the rotating rod 11.

[0030] The volume adjustment member provided in the pulling float 7 facilitates the adjustment of the buoyancy of the pulling float 7 during installation of the ocean buoy, and the buoyancy of the pulling float 7 can be adjusted according to the deadweight of the marine hydrological and meteorological observation buoy 1. The volume adjustment member includes an inner steel pipe 8, a water inlet hole 9, a limit tube 10, a rotating rod 11, a screw 13, a push plate 14 and a sealing gasket 15. The inner steel pipe 8 is welded to the inner surface of the pulling float 7, the water inlet hole 9 is provided at the lower part of the pulling float 7, and the water inlet hole 9 is located at the bottom of the inner steel pipe 8. The rotating rod 11 is installed in the limit tube 10 welded at the upper part of the pulling float 7, and a screw 13 is provided at the lower end of the rotating rod 11. The screw 13 is fixedly connected to the push plate 14 installed inside the inner steel pipe 8, and the sealing gasket 15 connected to the outer shell of the push plate 14 contacts the inner surface of the inner steel pipe 8. Rotating the rotating rod 11 can make the screw 13 screw into the screw hole at the upper end of the inner steel pipe 8, so that the screw 13 and the push plate 14 can move up and down in the inner steel pipe 8, so that the seawater inside the inner steel pipe 8 can enter or be discharged through the water inlet hole 9, which is convenient for adjusting the size of the internal volume of the pulling float 7.

[0031] A limit clamping plate 16 is integrally formed on the outer surface of the push plate 14 , a limit clamping groove 17 is formed on the inner surface of the sealing gasket 15 , and the limit clamping plate 16 is installed inside the limit clamping groove 17 .

[0032] See also Figure 1 , the mooring cable 5 is fixed to the center position of the lower end of the buoy 2.

[0033] See also Figure 1 The bending angle of the mooring cable 5 (i.e. the angle between the mooring cable 5 and the vertical direction between the pulling buoy 7 and the torpedo anchor 4) is 60°, and an anti-slip structure for limiting the mooring cable 5 is provided at the lower part of the fixed pulley 6.

[0034] The simulation results of torpedo anchors show that the relative positions of the center of gravity and the hydrodynamic center of the torpedo anchor must be considered when evaluating the stability of the anchor. In addition, increasing the weight of the torpedo anchor without changing its overall shape can greatly improve various hydrodynamic properties, mainly directional stability. In practical applications, it is generally adopted to fill the hollow shaft of the torpedo anchor with high density counterweights. Although it cannot achieve the effect of 2 times the average density of the original anchor body, it is still one of the most effective methods. Through research, it can also be known that the tail fin and slender body torpedo anchors can significantly improve the directional stability. Although these advantages are only applicable to a certain falling range as the former decreases, and the effect on directional stability is not obvious, the slight sacrifice of the falling speed is unacceptable. The latter can be said to be within the allowable range of penetrating the seabed and taking into account the life and cost of the torpedo anchor. The larger the value, the better, because it can have huge benefits on the hydrodynamic coefficient, especially the directional stability.

[0035] The working principle and use process of the new three-anchor large ocean observation buoy of the present invention that can resist the severe sea conditions of typhoons:

[0036] When in use, according to the pulling force required by the ocean hydrological and meteorological observation buoy 1, the rotating rod 11 is rotated. At this time, the rotating rod 11 moves inside the inner steel pipe 8 with the push plate 14 through the screw 13. At the same time, the seawater inside the inner steel pipe 8 is discharged from the water inlet 9, and the mooring cable 5 is passed around the fixed pulley 6 and fixedly connected with the pulling buoy 7. The torpedo anchor 4 is fixed at a suitable position on the seabed, and the torpedo anchor 4 is fixed to the buoy 2 through the mooring cable 5. The buoy 2 is fixedly connected to the ocean hydrological and meteorological observation buoy 1 through the pulling steel rope 3. The ocean hydrological and meteorological observation buoy 1 moves under the action of waves. At this time, the ocean hydrological and meteorological observation buoy 1 drives the buoy 2 to move by pulling the steel rope 3, and the buoy 2 drives the mooring cable 5 to move.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
