[0001] The invention relates to the technical field of deep-sea buoys, and in particular to a buoy fixing device. Background Art

[0002] Ocean buoys are anchored at sea and are used to collect ocean hydrological, water quality and meteorological data required for scientific research, energy development, port construction and national defense construction. Their main working environment is in severe weather and deep sea conditions. They need to meet long-term and continuous working requirements in severe sea conditions. The buoys need to avoid running away, chain breaking or drifting, so the anchoring technology inside the buoy is very important.

[0003] Offshore operations often involve harsh conditions, and most anchor release and recovery processes currently require personnel to go into the water or climb onto buoys to operate. When climbing onto buoys to operate, personnel need to work on the rear deck and use manpower to pull the anti-sway rope. This release and recovery method is inefficient, time-consuming, and has a high risk factor for operators, and may affect the safety of the instrument. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a buoy fixing and releasing device that can more conveniently fix and release and recover the buoy body and ensure the safety of personnel and instruments.

A locking mechanism for locking and unlocking the docking joint is provided in the sealing box body, and the waterproof part is tightly attached to the side wall of the docking joint in a way that it can be stretched open by the docking joint.

[0009] An annular groove is provided on the side wall of the docking joint, and the locking mechanism includes a push rod and a driving member. The push rod can be switched between a locked state in which it is clamped in the annular groove and an unlocked state away from the annular groove by moving. The driving member is connected to the push rod and drives the push rod to move to switch between the locked state and the unlocked state.

[0010] There are two push rods, and the two push rods can move relative to each other from two opposite sides of the annular groove to clamp the butt joints.

[0011] A slideway is provided in the sealing box body, and the push rod is slidably arranged in the slideway.

[0012] The sealing box body is provided with a limiting groove, and a pressure sensor for contacting the docking head is provided in the limiting groove, and the pressure sensor is used to detect whether the docking head is inserted into the through hole.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-Figure 5 As shown, the buoy fixing device of this embodiment includes a sealed box body 1 for installation on the buoy body 100, a traction rope 2 and a hoisting mechanism 21 for winding the traction rope 2 are arranged in the sealed box body 1, a through hole 3 for the traction rope 2 to pass through is arranged on the sealed box body 1, a waterproof member 4 is arranged on the through hole 3, the waterproof member 4 is in close contact with the traction rope 2 and can prevent water from entering the sealed box body 1, and the traction rope 2 extends through the through hole 3 to the end outside the sealed box body 1 and is detachably connected to the anchor system. The traction rope 2 can be driven by the hoisting mechanism 21 to conveniently control the distance between the buoy body 100 and the anchor system, and can be operated safely and quickly, so that the buoy body 100 can be fixed and recovered more conveniently. During the operation, there is no need for personnel to go into the water or climb onto the buoy body 100, which saves the time of offshore operations and ensures the safety of personnel and instruments.

[0028] In this embodiment, the end of the traction rope 2 is connected with a docking joint 5, a section of the docking joint 5 close to the end of the traction rope 2 can be inserted into the through hole 3, and can be separated from the through hole 3 under the action of gravity when the hoisting mechanism 21 is in a free state, a locking mechanism 6 for locking and unlocking the docking joint 5 is provided in the sealing box body 1, and the waterproof member 4 is closely attached to the side wall of the docking joint 5 in a manner that it can be stretched open by the docking joint 5. The docking joint 5 is convenient for connection with the anchor system and also convenient for fixing the connection position between them.

[0029] In this embodiment, an annular groove 51 is provided on the side wall of the docking head 5, and the locking mechanism 6 includes a push rod 61 and a driving member 62. The push rod 61 can be switched between a locked state in the annular groove 51 and an unlocked state away from the annular groove 51 by moving. The driving member 62 is connected to the push rod 61 and drives the push rod 61 to move to switch between the locked state and the unlocked state. The annular groove 51 and the push rod 61 form a lock structure, making locking and unlocking easier to operate.

[0030] In this embodiment, two push rods 61 are provided, and the two push rods 61 can move relative to each other from opposite sides of the annular groove 51 to clamp the butt joint 5. By clamping the butt joint 5 relative to each other, the butt joint 5 can be locked more stably.

[0031] In this embodiment, a slideway 63 is provided in the sealed box body 1, and the push rod 61 is slidably arranged in the slideway 63. The slideway 63 can make the push rod 61 run more smoothly.

[0032] In this embodiment, a limiting groove 7 is provided in the sealing box body 1, and a pressure sensor 71 for contacting the docking head 5 is provided in the limiting groove 7, and the pressure sensor 71 is used to detect whether the docking head 5 is inserted into the through hole 3. The pressure sensor 71 facilitates the realization of the automatic control function, thereby improving the working efficiency.

[0033] In this embodiment, the end of the butt joint 5 away from the end of the traction rope 2 is provided with a lifting ring 52 connected to the anchor system. The lifting ring 52 is convenient for connecting to the anchor system, and its processing and manufacturing are simple.

[0034] In this embodiment, the hoisting mechanism 21 includes a drum 211 for winding the traction rope 2, and a locking wheel 212 provided at the side end of the drum 211 for locking and unlocking the drum 211. A hydraulic transmission system 8 is provided in the sealed box body 1, and the hydraulic transmission system 8 is controlled and connected with the locking wheel 212 and the driving member 62. The locking wheel 212 and the driving member 62 are conveniently controlled simultaneously by the hydraulic transmission system 8, so that they have a linkage effect, so that the traction rope 2 and the docking head 5 can be better controlled.

[0035] In this embodiment, a pulley 22 is provided in the sealed box body 1, and the traction rope 2 wound on the reel 211 is guided to the through hole 3 through the pulley 22. Through the guiding effect of the pulley 22, the reel 211 can be installed more conveniently, thereby facilitating assembly.

[0036] In this embodiment, the waterproof member 4 is an O-ring. The O-ring is deformable and has a very small hole in the middle, which allows the traction rope 2 to pass through. Because the hole is squeezed, the O-ring is tightly attached to the traction rope 2. When the docking head 5 is retracted, the hole is squeezed larger, the O-ring is more tightly attached to the docking head 5, and is squeezed by the shell of the sealing box body 1 and the lower part of the docking head 5, thereby further playing a waterproof role.

[0037] The buoy body 100 is provided with a lifting lug 101, an impact protection pad, a stress wave barrier, a solar power generation device, a cable, an observation platform, and a central platform.

[0038] The specific working process is:

[0039] The buoy fixing device of the present invention is mainly installed at the bottom of the buoy body 100. When the anchor system needs to be deployed, a special ship is first used to carry the buoy body 100 and the anchor system to the required deployment sea area. At this time, the traction rope 2 and the docking head 5 in the sealing box body 1 are separated, the traction rope 2 is connected to the lifting ear 101, and the docking head 5 is left on the special ship. The anchor system is connected to the lifting ring 52, and then the buoy body 100 is placed in the designated sea area. After the buoy body 100 is stable, the traction rope 2 on the lifting ear 101 is connected to the docking head 5 on the ship. After the connection is completed, the docking head 5 and the anchor system are slowly placed into the sea, and the hoisting motor of the hoisting mechanism 21 starts to run. The hoisting motor is connected to the reducer through a coupling to drive the reducer to operate. The reducer converts the high-speed and small torque of the hoisting motor into a low-speed and large torque. The reducer is connected to one side of the drum 211 through a coupling. The drum 211 is driven to rotate, and the drum 211 is wound around the traction rope 2. The traction rope 2 is connected to the docking joint 5 through the pulley 22. The traction rope 2 pulls the docking joint 5 into the through hole 3. When the pressure sensor 71 in the limit groove 7 monitors the pressure of the docking joint 5, the driving member 62 is started, that is, the hydraulic pump motor is connected to the hydraulic pump through a coupling to drive the hydraulic pump to operate. The hydraulic pump is connected to the oil tank and the electromagnetic hydraulic valve group through pipelines and pipelines respectively. The oil tank is connected to the electromagnetic hydraulic valve group through pipelines. The electromagnetic hydraulic valve group is connected to the locking wheel 212 through pipelines. The locking wheel 212 is locked, and the drum 211 stops rotating. At the same time, the electromagnetic hydraulic valve group is connected to the hydraulic cylinder through pipelines and pipelines. The driving member 62 drives the push rod 61 to slide in the slideway 63, and the push rod 61 clamps the docking joint 5, that is, the connection between the anchor system and the buoy body 100 and the deployment in the sea area are completed.

[0040] When the anchor system needs to be recovered, the hydraulic cylinder and the locking wheel 212 are started simultaneously through the electromagnetic hydraulic valve group, and the driving member 62 drives the push rod 61 to slide in the slide 63, and the push rod 61 loosens the docking joint 5. At the same time, the locking wheel 212 is unlocked, and the drum 211 can rotate. Due to the gravity of the anchor system, the docking joint 5 begins to sink slowly, and the traction rope 2 drives the drum 211 to rotate through the pulley 22. Due to the gravity of the anchor system, the traction rope 2 and the docking joint 5 slip off the buoy body 100 and begin to sink slowly. When the anchor system sinks to a certain position, the operator salvages the buoy body 100, and salvages the docking joint 5 together with the anchor system through the traction rope 2, thus completing the recovery of the anchor system under the no-load state.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
