Description

Technical Field

[0001] This utility model belongs to the field of marine buoy monitoring technology, and specifically relates to a marine radioactive buoy data monitoring device. Background Technology

[0002] For long-term tracking of radioactive contamination in deep-sea or offshore areas with a water depth of less than 200m, fixed-moor buoy monitors are the core equipment for achieving "long-distance, high-stability monitoring". Fixed mooring can be a single-point anchor, a multi-point anchor, or a fixed-point buoy chain. However, fixed-moor buoy monitors have a most common and fatal failure: cable breakage. Long-term corrosion of the cable by seawater will continuously weaken the connection strength. Under the action of ship collisions or the strong lateral wave thrust caused by typhoons, it is very easy to break. After the breakage, the mooring and underwater sensor will fall to the seabed, which not only makes it impossible for the observation section to maintain a vertical state and the data collection to fail, but may also cause permanent damage to the sensor due to the pressure of the ultra-deep water.

[0003] According to the existing technology announcement number CN221938415U, a composite cable for mounting underwater real-time monitoring sensors on an ocean buoy includes: a sea surface buoy body, and a safety connection cable structure installed on the sea surface buoy body; the safety connection cable structure includes: a connecting frame, a load-bearing communication cable assembly, several sensors, a maintenance auxiliary rope, an anchor chain, and a holding anchor.

[0004] Further search revealed a buoy-type multi-functional dynamic monitoring device (CN220039452U), comprising a buoy body, a mooring system, an intelligent monitoring and control terminal, a solar power supply system, and measuring sensors. The mooring system includes anchor chains, anchors, and underwater piles. Two anchors are provided. The lower surface edge of the buoy body is connected to the two anchors and the underwater piles respectively via equally spaced anchor chains and fixed to the bottom silt. The intelligent monitoring and control terminal is equipped with a communication transmission module. The intelligent monitoring and control terminal and the solar power supply system are respectively located on the upper surface of the buoy body. Multiple measuring sensors are provided and respectively fixed on the lower surface of the buoy body and the underwater piles.

[0005] None of the existing technologies mentioned above offer an optimized solution for the problem of cable breakage in fixed-moor buoy monitors. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a marine radioactive buoy data monitoring device, which greatly improves the overall device's ability to resist the impact of seabed currents and wind and waves, and reduces the risk of cable breakage.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A marine radioactive buoy data monitoring device includes a main buoy, monitoring equipment, a main cable II, an anchor chain, a secondary buoy, and a flexible connection assembly. The main buoy has a main cable I at its bottom, with the top and middle sections of the main cable I forming a vertically distributed monitoring section. The monitoring equipment is connected to the middle section of the main cable I. The end of the main cable I is connected to the top of the main cable II via the flexible connection assembly. The end of the main cable II is connected to the anchor chain via the flexible connection assembly, and an anchor is provided at the end of the anchor chain. The secondary buoy is located on one side of the main buoy, with a secondary cable at its bottom. The end of the secondary cable is connected to the top of the main cable II via the flexible connection assembly. The secondary buoy has a winding mechanism inside, and the top of the secondary cable is connected to the winding mechanism.

[0009] The total length of the main cable I and the main cable II must be greater than the depth of the seawater.

[0010] The main buoy includes a main cable I, a solar power generation system, an anemometer, a rotating frame, and a control box. A battery compartment is located at the top of the main buoy, and a solar power generation system is installed on top of the battery compartment. The control box is located at the top of the solar power generation system. An anemometer is installed at the top of the main buoy. A guardrail surrounds the main buoy, and a fixed shell is located at the bottom of the main buoy. Two sets of sliding grooves are provided on the side wall of the fixed shell. The rotating frame is located inside the fixed shell and is rotatably connected to the fixed shell through the sliding grooves on the side wall of the fixed shell. The rotating frame is fixedly connected to the main cable I.

[0011] The auxiliary buoy includes an auxiliary cable, a counterweight, and a winding mechanism. The top device of the auxiliary buoy is the same as that of the main buoy. The difference between the auxiliary buoy and the main buoy is that the bottom of the auxiliary buoy is provided with a mounting shell. The winding mechanism is installed on one side of the mounting shell, and the counterweight is installed on the other side of the mounting shell. The top of the auxiliary cable passes through the mounting shell and is connected to the winding mechanism.

[0012] The cross-sectional diameter of the secondary cable is lower than that of the main cable I.

[0013] The winding mechanism includes a winding shaft, motor I, a fixed plate, a fixed frame, a reciprocating screw, and a moving block. Two sets of fixed plates are symmetrically arranged and fixedly connected to one side of the mounting housing. A bearing seat is located on the top of the fixed plate. Both ends of the winding shaft are rotatably connected to the fixed plate via the bearing seat on the top of the fixed plate. A synchronous pulley is located at one end of the winding shaft. The fixed frame is fixedly connected to one side of the fixed plate. A sliding rod is located on the fixed frame, and a reciprocating screw is located on one side of the sliding rod. The reciprocating screw is rotatably connected to the fixed frame. The thread length of the reciprocating screw is the same as the length of the winding shaft. A synchronous pulley is located at one end of the reciprocating screw, and this pulley is connected to the synchronous pulley at one end of the winding shaft via a synchronous belt. Motor I is mounted on one side of the winding shaft, and its output shaft is fixedly connected to the winding shaft. The moving block is slidably connected to the sliding rod and is movably connected to the reciprocating screw via a helical groove on the reciprocating screw. A traction block is located on the top of the moving block. The top of the auxiliary cable passes through the mounting housing and is connected to the winding shaft via the traction block.

[0014] The motor I is a reversible motor.

[0015] The elastic connection component includes a mounting sleeve shaft and a sliding block; the ends of the main cable I, main cable II, and auxiliary cable are all connected to the elastic connection component. There are two sets of sliding blocks, which are slidably installed at the upper and lower ends of the mounting sleeve shaft respectively. The part of the sliding block located on the mounting sleeve shaft is provided with a spring, and the top of the spring is provided with a damping block. The sliding block and the damping block are movably connected.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1) The motor I of the winding mechanism drives the winding shaft to rotate, which in turn drives the traction block to wind the line at a constant speed, so that the auxiliary cable gradually tightens. The auxiliary cable pulls the main cable II upward. Combined with the design that the total length of the main cable I and the main cable II is greater than the seawater depth, the main cable I bends naturally to form a buffer margin, thereby releasing the tension of the main cable I. This prevents the main cable I from being over-tensioned due to excessive instantaneous force and breaking. This ensures that the monitoring equipment can stably monitor radioactive pollutants in the ocean. Compared with the taut anchored buoy, it greatly improves the overall ability of the device to resist the impact of seabed currents and the ability to resist wind and waves, and reduces the risk of the device breaking.

[0018] 2) When the device encounters a minor collision with a ship or strong waves, the elastic connection component uses a sliding block to compress the spring to buffer the impact force, and a damping block to weaken the oscillation, thereby reducing the tension between the cable connections and reducing the risk of cable breakage.

[0019] 3) If the main cable I or main cable II breaks, the auxiliary buoy winding mechanism will immediately reel in the auxiliary cable to pull the monitoring equipment to prevent it from falling into the deep sea and causing damage. Attached Figure Description

The secondary buoy 2 has a winding mechanism 23 inside, and the top of the secondary cable 21 is connected to the winding mechanism 23.

[0028] The total length of the main cable I 101 and the main cable II 103 must be greater than the depth of the seawater.

[0029] The main buoy 1 includes a main cable I 101, a solar power generation system 106, an anemometer 109, a rotating frame 111, and a control box 112.

[0030] It should be emphasized that the power generation technology of the solar power generation system 106 is existing technology, providing auxiliary power for the entire device.

The specific model of the monitoring device 102 is CNNC Lixin NAVA-UW underwater online monitoring gamma spectrometer. The basic working principle of the NAVA-UW underwater online monitoring gamma spectrometer is to use a detector to convert gamma rays of different energies into corresponding electrical pulse signals.

The detector used in the NAVA-UW system is a 3×3 NaI(Tl) scintillator detector. NaI(Tl) is a commonly used scintillator material. When gamma rays pass through the detector, they interact with the NaI(Tl) crystal to generate scintillating light. This scintillating light is converted into electrical signals by a photomultiplier tube, thereby realizing the detection and energy measurement of gamma rays.

[0032] The auxiliary buoy 2 includes an auxiliary cable 21, a counterweight 22, and a winding mechanism 23. The top device of the auxiliary buoy 2 is the same as the top device of the main buoy 1.

The top end of the auxiliary cable 21 passes through the mounting shell 24 and is connected to the winding mechanism 23.

[0033] The cross-sectional diameter of the auxiliary cable 21 is lower than that of the main cable I;

[0034] The winding mechanism 23 includes a winding shaft 2301, a motor 2302, a fixed plate 2303, a fixed frame 2304, a reciprocating screw 2305, and a moving block 2307. Two sets of fixed plates 2303 are symmetrically arranged and are fixedly connected to one side of the mounting housing 24. A bearing seat is provided at the top of the fixed plate 2303. Both ends of the winding shaft 2301 are rotatably connected to the fixed plate 2303 via the bearing seat at the top of the fixed plate 2303. A synchronous pulley is provided at one end of the winding shaft 2301. The fixed frame 2304 is fixedly connected to one side of the fixed plate 2303. A sliding rod 2306 is provided on the fixed frame 2304, and a reciprocating screw 2305 is provided on one side of the sliding rod 2306. The reciprocating screw 2305 is connected to the fixed frame 2307. 4. Rotary connection: The thread length of the reciprocating screw 2305 is the same as the length of the winding shaft 2301. One end of the reciprocating screw 2305 is provided with a synchronous pulley. The synchronous pulley at one end of the reciprocating screw 2305 is connected to the synchronous pulley at one end of the winding shaft 2301 through a synchronous belt. The motor I 2302 is installed on one side of the winding shaft 2301. The output shaft of the motor I 2302 is fixedly connected to the winding shaft 2301. The moving block 2307 is slidably connected to the sliding rod 2306. The moving block 2307 is movably connected to the reciprocating screw 2305 through the spiral groove on the reciprocating screw 2305. The top of the moving block 2307 is provided with a traction block 2308. The top end of the auxiliary cable 21 passes through the mounting shell 24 and is connected to the traction block 2308 and the winding shaft 2301.

[0035] The motor I2302 is a reversible motor;

[0036] The elastic connection component 3 includes a mounting sleeve shaft 31 and a sliding block 32; the ends of the main cable I 101, main cable II 103, and auxiliary cable 21 are all connected to the elastic connection component 3. There are two sets of sliding blocks 32, which are slidably installed at the upper and lower ends of the mounting sleeve shaft 31 respectively. The part of the sliding block 32 located on the mounting sleeve shaft 31 is provided with a spring 34, and the top of the spring 34 is provided with a damping block 33. The sliding block 32 and the damping block 33 are movably connected.

[0037] A marine radioactive buoy data monitoring device operates as follows:

[0038] After the equipment is deployed to the target waters, anchor 105 sinks to the seabed to secure the entire device. Before anchor 105 sinks, the winding mechanism 23 inside the auxiliary buoy 2 releases a sufficiently long auxiliary cable 21 to prevent damage to the winding mechanism 23 when anchor 105 sinks, as the cable release speed of the winding mechanism 23 may not match the sinking speed of anchor 105. Because the total length of main cable I 101 and main cable II 103 exceeds the actual water depth, motor I 2302 of the winding mechanism 23 inside the auxiliary buoy 2 drives the winding shaft 2301 to rotate, cooperating with the reciprocating screw. 2305 drives the traction block 2308 to retract the line at a uniform speed, so that the auxiliary cable 21 is gradually tightened. The auxiliary cable 21 pulls the main cable II 103 upward, so that the main cable I 101 bends naturally to form a buffer margin, thereby releasing the tension of the main cable I 101. This prevents the main cable I 101 from being over-tensioned due to excessive instantaneous force and breaking, ensuring that the monitoring equipment 102 can stably monitor radioactive pollutants in the ocean. Compared with the taut anchored buoy, it greatly improves the overall device's ability to resist the impact of seabed currents and its ability to resist wind and waves.

[0039] The monitoring device 102 in the middle section of the main cable I101 is activated. It captures gamma rays in seawater through a NaI (Tl) scintillator, converts them into fluorescent photons, and then converts them into electrical signals through a photomultiplier tube. After amplification and separation, the data on the types and activities of nuclides are obtained.

[0040] When the device encounters a minor collision with a ship or strong waves, the elastic connection component 3 uses a sliding block to compress the spring to buffer the impact force, and a damping block to weaken the oscillation, thereby reducing the tension between the cable connections and reducing the risk of cable breakage.

[0041] If the main cable I 101 or the main cable II 103 breaks, the auxiliary buoy 2 winding mechanism 23 immediately winds up the auxiliary cable 21, pulling the monitoring equipment 102 to prevent it from falling into the deep sea and causing damage. At the same time, the main buoy 1 control box sends a cable break alarm, and the solar power generation system 106 on the top of the main buoy 1 continues to generate power. The monitoring data and alarm information are transmitted to the shore-based center in real time to ensure long-term stable monitoring.
