Description

Technical Field

[0001] This invention relates to the technical field of marine monitoring buoys, and more particularly to a marine buoy for monitoring nuclear wastewater discharge. Background Technology

[0002] Currently, some nuclear power plants directly discharge nuclear wastewater into the surrounding ocean. However, this wastewater contains various radioactive substances. The discharge of nuclear wastewater into the ocean not only affects the marine ecological environment of the discharge area, but also spreads to global ocean areas with ocean currents, posing a threat to global marine ecology and human health. The activity concentration of radionuclides in the marine environment is low, and traditional monitoring methods are difficult to effectively detect and assess the actual radioactivity level of the target sea area. The marine buoy radiation online monitoring system can monitor seawater in real time and continuously, providing "instant warning" monitoring for early prediction of accidents or early alarm of environmental pollution levels.

[0003] After nuclear wastewater is discharged, it will spread over a wide area of ​​the ocean. Multiple monitoring points need to be set up in different sea areas. Marine buoys can serve as mobile monitoring platforms and be deployed in near-shore nuclear radiation environments and nuclear emergency application scenarios. While completing in-situ monitoring of radioactive materials, they can also use GPS and other systems to determine the location information of the waters where the radioactive materials are located and the radiation dose intensity.

[0004] While existing marine buoys can effectively monitor the sea area at the monitoring points, they still have the following problems: The existing buoy monitoring probes are usually located inside the ocean, while the signal lines used for signal transmission are located on the ocean surface. Ocean currents often generate waves, which can overturn the buoy. If the waves are too large, causing the buoy to flip 180°, the buoy will remain upside down and unable to right itself. The monitoring probe is located above the ocean surface, while the signal line is inside the ocean, making it impossible for the buoy to effectively monitor the seawater. Furthermore, prolonged immersion of the signal line in seawater can damage it. Additionally, when the buoy monitors the seawater through the probe for extended periods, a large amount of microorganisms and algae will adhere to its surface. These deposits will affect the probe's monitoring data. Because there are many buoys at sea and they are widely dispersed, it is impossible to manually clean the probe surface periodically. Therefore, a marine buoy needs to be designed that can periodically clean the deposits on the probe surface. Summary of the Invention

[0005] In view of the problems of existing technologies, such as the inability to monitor after the floating object capsizes at sea and the inability to effectively clean the surface of the monitoring probe, a marine buoy for monitoring nuclear wastewater discharge is proposed.

[0006] This application provides a marine buoy for monitoring nuclear wastewater discharge. Its purpose is to: by setting up monitoring components, make the weight of the wet chamber of the monitoring ball much greater than the weight of the dry chamber, so that when the buoy encounters waves and capsizes, the monitoring ball can adjust under the action of gravity, ensuring that the wet chamber with the probe is always inside the seawater and the signal line is always above, thus ensuring the normal monitoring of the seawater buoy; by setting up cleaning components, the cleaning components can periodically clean the deposits on the surface of the probe, avoiding the accumulation of deposits from affecting the subsequent monitoring of the probe.

[0007] The technical solution of the present invention is as follows: a marine buoy for monitoring nuclear wastewater discharge, comprising a floating ring, an installation ring groove formed on the outer wall of the floating ring, a rubber airbag disposed in the installation ring groove, and a monitoring unit disposed on the floating ring, the monitoring unit comprising a monitoring component disposed on the inner ring of the floating ring and a cleaning component;

[0008] The monitoring component includes two mounting blocks disposed on the inner wall of the floating ring, two rotating shafts disposed on the inner walls of the two mounting blocks respectively, a monitoring ball disposed between the two rotating shafts, a partition plate disposed on the inner wall of the monitoring ball, a dry cavity opened inside the monitoring ball and located above the partition plate, a wet cavity opened inside the monitoring ball and located below the partition plate, and a monitor disposed on the upper part of the partition plate.

[0009] The floating ring, mounting block, and monitoring ball are all made of titanium alloy. The dry chamber is filled with air, and the monitor is located inside the dry chamber. The wet chamber is filled with seawater. A signal transmission component is provided at the upper end of the monitoring ball, and a detection component is provided at the lower end of the monitoring ball.

[0010] Furthermore, the signal transmission component includes a square plate disposed on the upper end of the monitoring ball, a circular pad disposed on the upper end of the square plate, and a signal line disposed on the upper end of the circular pad.

[0011] Furthermore, the signal line is an active flexible antenna, and the outer layer of the signal line is wrapped with high-quality plastic. The plastic has strong aging resistance and certain seawater corrosion resistance, and has a long service life. The signal line is electrically connected to the monitor.

[0012] Furthermore, the detection assembly includes a cleaning cylinder disposed below the monitoring ball, a circular groove formed at the lower end of the cleaning cylinder, a sliding cylinder slidably disposed inside the circular groove, a detection head disposed at the lower end of the sliding cylinder, an extension column disposed at the lower end of the detection head, and a sealing rubber disc disposed at the lower end of the extension column. The detection head is connected to the monitor via signal. A contraction element is installed at the upper end of the sliding cylinder, and a cleaning element is installed at the upper end of the cleaning cylinder.

[0013] Furthermore, the shrinking element includes a transformer cylinder disposed on the upper end of the partition plate, a hydraulic cylinder disposed on the upper end of the transformer cylinder, a piston plate slidably disposed on the inner wall of the transformer cylinder, a piston rod disposed between the piston plate and the telescopic end of the hydraulic cylinder, a connecting plate disposed on the inner wall of the sliding cylinder, and a linkage rod disposed between the lower end of the piston plate and the upper end of the connecting plate. The linkage rod is respectively sealed and slidably disposed on the lower end of the transformer cylinder and the middle part of the partition plate. The transformer cylinder is provided with water inlet and outlet components.

[0014] Furthermore, the water inlet and outlet components include a water inlet hole and a water outlet hole opened at the lower end of the transformer cylinder, a water inlet pipe disposed on the inner ring of the water inlet hole, one end of the water inlet pipe being located at the lower end of the monitoring ball, a one-way pipe one disposed at one end of the water inlet pipe, a water outlet pipe disposed on the inner wall of the water outlet hole, one end of the water outlet pipe being located inside the cleaning cylinder, and a one-way pipe two disposed at one end of the water outlet pipe.

[0015] Furthermore, multiple one-way valves are evenly spaced at the lower end of the cleaning cylinder.

[0016] Furthermore, the cleaning component includes a rotating gear ring disposed at the upper end of the cleaning cylinder, a synchronization ring disposed on the inner wall of the rotating gear ring, multiple rotating plates evenly and equidistantly disposed at the lower end of the synchronization ring with the center of the synchronization ring as the axis, brush rods disposed on the side walls of the multiple rotating plates, two servo motors disposed at the upper end of the partition plate, two rotating rods disposed at the driving ends of the two servo motors, and two driving gears disposed at the lower ends of the two rotating rods. The two driving gears mesh with the two ends of the rotating gear ring respectively, and the rotation directions of the driving ends of the two servo motors are always opposite.

[0017] Furthermore, the wet cavity is equipped with a counterweight for increasing gravity, and the counterweight is made of lead.

[0018] The beneficial effects of this invention are:

[0019] 1. By setting up a dry cavity and a wet cavity inside the monitoring ball, and setting up a configuration block inside the wet cavity, the weight of the wet cavity is greater than that of the dry cavity. As a result, when the buoy is overturned by the impact of the waves, the wet cavity of the monitoring ball rotates along the axis of rotation under the action of gravity, always automatically adjusting and being located at the bottom. This ensures that the probe is always inside the seawater, while the signal line is always above the seawater surface, ensuring the normal monitoring of the monitoring ball and improving the stability of the buoy's monitoring on the sea surface.

[0020] 2. By setting up a cleaning component, the cleaning component can periodically clean the accumulated deposits on the surface of the probe head without manual intervention. This prevents the long-term accumulation of deposits on the probe head from affecting the probe head's detection data, ensuring normal monitoring of the probe head, reducing the workload of staff, and improving the accuracy and stability of the monitoring data from the monitoring ball.

[0021] 3. By setting up water inlet and outlet components, after the cleaning component has cleaned the surface of the probe, most of the cleaned-up material can be automatically flushed out of the monitoring ball, ensuring the cleanliness of the inside of the monitoring ball and facilitating the later maintenance and cleaning of the monitoring ball.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Example 1, referring to Figures 1-6 The first embodiment of the present invention provides a marine buoy for monitoring nuclear wastewater discharge, including a floating ring 1, an installation ring groove 2 formed on the outer wall of the floating ring 1, a rubber airbag 3 fixedly installed in the installation ring groove 2, and a monitoring unit installed on the floating ring 1. The monitoring unit includes a monitoring component and a cleaning component installed on the inner ring of the floating ring 1.

[0036] The monitoring components include two mounting blocks 4 fixedly installed on the inner wall of the floating ring 1, two rotating shafts 5 respectively rotatably installed on the inner walls of the two mounting blocks 4, a monitoring ball 6 fixedly installed between the two rotating shafts 5, a partition plate 7 fixedly installed on the inner wall of the monitoring ball 6, a dry cavity 10 opened inside the monitoring ball 6 and located above the partition plate 7, a wet cavity 11 opened inside the monitoring ball 6 and located below the partition plate 7, and a monitor 12 fixedly installed on the upper end of the partition plate 7.

[0037] The floating ring 1, mounting block 4, and monitoring ball 6 are all made of titanium alloy. The dry chamber 10 is filled with air, and the monitor 12 is located inside the dry chamber 10. The wet chamber 11 is filled with seawater. The upper end of the monitoring ball 6 is equipped with a signal transmission component, and the lower end of the monitoring ball 6 is equipped with a detection component.

[0038] Reference Figure 3 and Figure 4The signal transmission assembly includes a square plate 13 fixedly mounted on the upper end of the monitoring ball 6, a circular pad 14 fixedly mounted on the upper end of the square plate 13, and a signal line 15 fixedly mounted on the upper end of the circular pad 14. The signal line 15 is an active flexible antenna, and its outer layer is wrapped with high-quality plastic, which has strong aging resistance and certain seawater corrosion resistance, resulting in a long service life. The signal line 15 is electrically connected to the monitor 12. A counterweight 8 for increasing gravity is fixedly installed inside the wet chamber 11. The counterweight 8 is made of lead.

[0039] Specifically, both the floating ring 1 and the rubber airbag 3 are circular. The floating ring 1 is used to support the monitoring ball 6, and the rubber airbag 3 is used to provide buoyancy for the whole, ensuring that the rubber airbag 3 can carry the monitoring ball 6 and always float on the ocean surface. A protective plate (not shown in the figure) is fixedly installed on the outer wall of the rubber airbag 3. The protective plate is used to protect the outer wall of the rubber airbag 3 and prevent floating objects on the sea surface from scratching and damaging the rubber airbag 3 under the impact of the waves, which would cause the rubber airbag 3 to leak and the monitoring ball 6 to sink.

[0040] The monitoring ball 6 in the monitoring component is rotatably mounted on the inner wall of the floating ring 1 via a rotating shaft 5. The floating ring 1 can propel the monitoring ball 6 to float on the sea surface via a rubber airbag 3. Simultaneously, the wet chamber 11 of the monitoring ball 6 is filled with seawater and equipped with a counterweight 8. The counterweight 8 ensures that the weight in the wet chamber 11 is significantly greater than the weight in the dry chamber 10. This allows the monitoring ball 6 to rotate along the rotating shaft 5 even if the floating ring 1 is overturned by waves (i.e., flipped 180°), due to its own weight deviation. This ensures that the wet chamber 11 remains inside the seawater, while the signal line 15 at the upper end of the dry chamber 10 remains above the sea surface. This effectively ensures the normal monitoring of the marine buoy. Meanwhile, the signal line 15 is an active flexible antenna. When the floating ring 1 is overturned, the signal line 15 can bend when the monitoring ball 6 is adjusting its rotation, ensuring that the monitoring ball 6 can rotate and adjust normally. In addition, the signal line 15 is wrapped with high-quality plastic. Even if the signal line 15 comes into contact with seawater, the plastic can effectively protect the inside of the signal line 15 from contact with seawater. The plastic has strong aging resistance and a certain degree of seawater corrosion resistance, which improves the service life of the signal line 15 and ensures that the marine buoy can carry out monitoring tasks for a long time.

[0041] The dry chamber 10 is used to house the drive equipment and electronic components. The partition plate 7 separates the dry chamber 10 from the wet chamber 11, preventing seawater from entering the dry chamber 10 and damaging the internal electronic components and drive equipment. At the same time, the dry chamber 10 can effectively improve the overall buoyancy of the monitoring ball 6, ensuring that the monitoring ball 6 can float more stably on the ocean surface.

[0042] Example 2, refer to Figures 1-3 as well as Figures 6-10This is the second embodiment of the present invention, which differs from the first embodiment in that: the detection component includes a cleaning cylinder 16 fixedly installed below the monitoring ball 6, a circular groove opened at the lower end of the cleaning cylinder 16, a sliding cylinder 17 slidably installed inside the circular groove, a detection head 18 fixedly installed at the lower end of the sliding cylinder 17, an extension column 19 fixedly installed at the lower end of the detection head 18, a sealing rubber disc 20 fixedly installed at the lower end of the extension column 19, the detection head 18 being signal-connected to the monitor 12, a shrinking element installed at the upper end of the sliding cylinder 17, and a cleaning element installed at the upper end of the cleaning cylinder 16. The shrinking element includes a transformer cylinder 21 fixedly installed on the upper end of the partition plate 7, a hydraulic cylinder 22 fixedly installed on the upper end of the transformer cylinder 21, a piston plate 23 slidably installed on the inner wall of the transformer cylinder 21, a piston rod 24 disposed between the piston plate 23 and the telescopic end of the hydraulic cylinder 22, a connecting plate 25 fixedly installed on the inner wall of the sliding cylinder 17, and a linkage rod 26 fixedly installed between the lower end of the piston plate 23 and the upper end of the connecting plate 25. The linkage rod 26 is respectively sealed and slidably located at the lower end of the transformer cylinder 21 and the middle part of the partition plate 7. Water inlet and outlet components are installed inside the transformer cylinder 21. The water inlet and outlet components include a water inlet hole 27 and a water outlet hole 28 located at the lower end of the transformer cylinder 21, a water inlet pipe 29 fixedly installed on the inner ring of the water inlet hole 27, one end of the water inlet pipe 29 being located at the lower end of the monitoring ball 6, a one-way pipe 30 fixedly installed at one end of the water inlet pipe 29, a water outlet pipe 31 fixedly installed on the inner wall of the water outlet hole 28, one end of the water outlet pipe 31 being located inside the cleaning cylinder 16, and a second one-way pipe 32 fixedly installed at one end of the water outlet pipe 31. Multiple one-way valves 33 are evenly spaced at the lower end of the cleaning cylinder 16.

[0043] Specifically, by setting up a sliding cylinder 17, a connecting plate 25, a piston plate 23, and a linkage rod 26 between the connecting plate 25 and the piston plate 23, when the piston plate 23 moves upward along the transformer cylinder 21, it can drive the sliding cylinder 17 to move upward synchronously through the linkage rod 26 and the connecting plate 25. When the sliding cylinder 17 moves upward, it drives the probe 18 at its lower end to move synchronously, so that the probe 18 enters the cleaning cylinder 16 and is cleaned inside the cleaning cylinder 16. Simultaneously, as the probe 18 slides upward into the monitoring ball 6, the pressure inside the transformer cylinder 21 decreases during the upward movement of the piston plate 23. At this time, under the action of pressure, the external seawater enters the transformer cylinder 21 through the one-way pipe 30 and the inlet pipe 29 for storage. After the probe 18 completes cleaning, it will move downward under the action of the linkage rod 26. At the same time, the piston plate 23 moves downward, and when the piston plate 23 moves downward, it injects the previously collected seawater into the cleaning cylinder 16 under pressure. When the seawater in the transformer cylinder 21 is injected into the cleaning cylinder 16, the pressure in the cleaning cylinder 16 increases. At this time, the seawater in the cleaning cylinder 16, mixed with the attached substances, is discharged into the sea through the one-way valve 33 under pressure. This can effectively prevent the presence of a large amount of attached substances in the cleaning cylinder 16, which would affect subsequent cleaning work.

[0044] The inlet and outlet directions of the one-way pipe 30 and the one-way pipe 32 are opposite. The one-way pipe 30 can only let water in but not out, while the one-way pipe 32 can only let water out but not in. The function of the extension column 19 and the sealing rubber disc 20 is to ensure that the circular groove is sealed when the probe 18 enters the cleaning cylinder 16. That is, through the cooperation of the extension column 19 and the sealing rubber disc 20, the probe 18 can completely enter the cleaning cylinder 16 for cleaning. At the same time, the extension column 19 and the sealing rubber disc 20 are tightly attached to the circular groove to ensure the sealing of the circular groove (that is, the extension column 19 and the sealing rubber disc 20 do not participate in the cleaning process).

[0045] The remaining structure is the same as that in Example 1.

[0046] Example 3, referring to Figures 5-7This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the cleaning component includes a rotating gear ring 34 rotatably mounted on the upper end of the cleaning cylinder 16, a synchronization ring 35 fixedly mounted on the inner wall of the rotating gear ring 34, a plurality of rotating plates 36 uniformly and equidistantly fixedly mounted on the lower end of the synchronization ring 35 with the center of the synchronization ring 35 as the axis, brush rods 37 respectively fixedly mounted on the side walls of the plurality of rotating plates 36, two servo motors 38 fixedly mounted on the upper end of the partition plate 7, two rotating rods 39 respectively fixedly mounted on the driving ends of the two servo motors 38, and two driving gears 9 respectively fixedly mounted on the lower ends of the two rotating rods 39. The two driving gears 9 respectively mesh with the two ends of the rotating gear ring 34, and the rotation directions of the driving ends of the two servo motors 38 are always opposite.

[0047] Specifically, two drive gears 9 drive the rotating gear ring 34 to rotate, which in turn drives the brush rod 37 to rotate synchronously. Soft brushes are installed on the side walls of the brush rod 37. The rotating brushes clean the deposits on the surface of the probe head 18, removing them and cooperating with the inlet / outlet water fittings to flush the removed deposits back into the sea. This completes the cleaning of the probe head 18's surface. Regular cleaning ensures the normal monitoring of the probe head 18, preventing deposits from interfering with its operation and causing inaccurate monitoring data. The servo motor 38 is located inside the dry chamber 10, effectively preventing it from contacting seawater and causing damage, thus extending the device's lifespan. Furthermore, cleaning the probe head 18 requires no manual intervention, greatly reducing the workload and maintenance requirements for staff.

[0048] The remaining structure is the same as that in Example 2.

[0049] Based on embodiments 1-3, the working principle of this invention is as follows: The operator activates the monitor 12 and places the buoy in the designated sea area. Because the overall mass of the wet cavity 11 of the monitoring ball 6 is greater than the mass of the dry cavity 10 area, the monitoring ball 6 rotates around the pivot 5, causing the wet cavity 11 to be located below (i.e., inside the seawater). The probe 18 at the lower end of the wet cavity 11 is located inside the seawater, and the signal line 15 at the upper end of the dry cavity 10 is located above the seawater surface. The probe 18, located inside the seawater, monitors the nuclear radiation in the seawater in real time, and the signal line 15 transmits the real-time monitoring data to the backend. When the buoy is overturned by waves (deflected 180°), even if the floating ring 1 flips 180°, the monitoring ball 6 still deflects and adjusts left, right, and downward due to uneven mass, causing the wet cavity 11 and the probe 18 at the lower end to be located inside the seawater again for monitoring, while the signal line 15 transmits the signal above the seawater surface.

[0050] When the probe 18 is monitoring in seawater for a certain period of time, the hydraulic cylinder 22 and two servo motors 38 are activated under the control of the background system. The extension end of the hydraulic cylinder 22 moves upward, which in turn drives the piston plate 23 to move upward through the piston rod 24. During the upward movement of the piston plate 23, the sliding cylinder 17 moves upward synchronously through the linkage rod 26, so that the sliding cylinder 17 carries the probe 18 into the cleaning cylinder 16 to prepare for cleaning. At the same time, during the upward movement of the piston plate 23, seawater around the monitoring ball 6 is sucked into the transformer cylinder 21 for storage. Just before the probe 18 enters the cleaning cylinder 16, the transformer cylinder 21 is filled with seawater.

[0051] When the probe head 18 enters the cleaning cylinder 16, the two servo motors 38 start and drive the corresponding rotating rods 39 to rotate through the drive end. The rotation of the rotating rods 39 drives the corresponding drive gears 9 to rotate synchronously. The two drive gears 9 rotate in opposite directions and together drive the rotating gear ring 34 to rotate. The rotation of the rotating gear ring 34 drives the synchronous ring 35 to rotate synchronously, so that the brush rod 37 at the lower end of the synchronous ring 35 rotates around the probe head 18 and cleans the deposits on the surface of the probe head 18, ensuring the cleanliness of the surface of the probe head 18.

[0052] After cleaning, the extension end of hydraulic cylinder 22 drives piston rod 24 downward, simultaneously moving piston plate 23, linkage rod 26, sliding cylinder 17, and probe head 18 downward. This allows probe head 18 to extend back into the ocean to continue monitoring the internal ocean area. Simultaneously, as piston plate 23 moves downward, it forces seawater out of transformer cylinder 21 and into cleaning cylinder 16 through one-way valve 32 on outlet pipe 31. The increased pressure inside cleaning cylinder 16 forces seawater out through one-way valve 33, preventing excessive deposits inside monitoring ball 6 from affecting subsequent cleaning. In other words, when probe head 18 exits cleaning cylinder 16, the seawater stored in transformer cylinder 21 is simultaneously discharged, along with the removed deposits.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
