Description

Technical Field

[0001] The invention relates to the technical field of buoys for marine monitoring, and in particular to a marine buoy for monitoring nuclear waste water discharge. Background Art

[0002] At present, nuclear waste water from some nuclear power plants is directly discharged into the surrounding oceans, but nuclear waste water contains a variety of radioactive substances. The discharge of nuclear waste water into the ocean will not only affect the marine ecological environment of the discharge area, but will also spread to global oceans with ocean currents, posing a threat to global marine ecology and human health. The activity concentration of radioactive nuclides in the marine environment is low, and traditional monitoring methods are difficult to effectively detect and evaluate the actual radioactivity level of the target sea area. The ocean buoy radiation online monitoring system can conduct real-time and continuous monitoring of seawater, providing "instant warning" monitoring for early prediction of accidents or early warning of environmental pollution levels.

[0003] After being discharged, nuclear waste water will spread over a vast sea area, and multiple monitoring points need to be set up in different sea areas. Offshore buoys can be used as mobile monitoring platforms and deployed in offshore nuclear radiation environments and nuclear emergency application scenarios. While completing the in-situ monitoring of radioactive materials, they can be combined with global positioning systems to determine the location information of the waters where the radioactive materials are located and information such as radiation dose intensity.

[0004] Although the existing offshore buoys can effectively monitor the sea areas at the monitoring points, the following problems still exist: the existing buoy monitoring probes are usually located inside the ocean and the signal lines used to transmit signals are located on the ocean surface. Waves often occur due to ocean flow. When the waves generate impact on the ocean buoy, the offshore buoy may be knocked down. If the waves are too large, causing the buoy to flip 180°, the buoy will remain overturned and unable to return to the right position. The monitoring probe is located above the ocean surface and the signal line is located inside the ocean. This makes it impossible for the buoy to effectively monitor the seawater, and the signal line may be damaged if it is soaked in seawater for a long time. At the same time, when the offshore buoy monitors the seawater for a long time through the probe, a large number of microorganisms and algae will be attached to its surface. These attachments will affect the monitoring data of the probe. Because there are many offshore buoys and they are widely dispersed, the probe surface cannot be cleaned regularly by humans. Therefore, it is necessary to design an offshore buoy that can regularly clean the attachments on the surface of the detection head. Summary of the invention

[0005] In view of the problems in the existing technology that floating buoys at sea may tip over, resulting in the inability to conduct subsequent monitoring and the inability to effectively clean the attachments on the surface of the monitoring probe, an offshore buoy for monitoring nuclear wastewater discharge is proposed.

[0006] The present application provides an offshore buoy for monitoring nuclear waste water discharge, the purpose of which is: by setting a monitoring component, the wet cavity weight of the monitoring ball is much greater than the dry cavity weight, and then when the buoy encounters waves and overturns, the monitoring ball can be adjusted under the action of gravity to ensure that the wet cavity with the detection head is always located inside the seawater and the signal line is always located above, thereby ensuring normal monitoring of the seawater buoy. By setting a cleaning component, the cleaning component can regularly clean the attachments on the surface of the detection head to avoid the accumulation of attachments affecting the subsequent monitoring of the detection head.

[0007] The technical solution of the present invention is: a marine buoy for monitoring nuclear wastewater discharge, comprising a floating ring, a mounting ring groove provided on the outer wall of the floating ring, a rubber airbag arranged in the mounting ring groove, and a monitoring unit arranged on the floating ring, wherein the monitoring unit comprises a monitoring component and a cleaning component arranged on the inner ring of the floating ring;

[0009] The floating ring, mounting block and monitoring ball are all made of titanium alloy. The dry cavity is filled with air. The monitor is located in the dry cavity. The wet cavity 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 arranged on the upper end of the monitoring ball, a circular pad arranged on the upper end of the square plate, and a signal line arranged on the upper end of the circular pad.

[0011] Furthermore, the signal line is an active soft antenna, 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 arranged below the monitoring ball, a circular groove opened at the lower end of the cleaning cylinder, a sliding cylinder slidably arranged inside the circular groove, a detection head arranged at the lower end of the sliding cylinder, an extension column arranged at the lower end of the detection head, and a sealing rubber disk arranged at the lower end of the extension column. The detection head is connected to the monitor 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 contraction element includes a transformer cylinder arranged on the upper end of the partition plate, a hydraulic cylinder arranged on the upper end of the transformer cylinder, a piston plate slidably arranged on the inner wall of the transformer cylinder, a piston rod arranged between the piston plate and the telescopic end of the hydraulic cylinder, a connecting plate arranged on the inner wall of the sliding cylinder, and a linkage rod arranged between the lower end of the piston plate and the upper end of the connecting plate. The linkage rod is sealed and slidable on the lower end of the transformer cylinder and the middle of the partition plate respectively, and water inlet and outlet parts are arranged inside the transformer cylinder.

[0014] Furthermore, the water inlet and outlet parts include a water inlet hole and a water outlet hole opened at the lower end of the transformer cylinder, a water inlet pipe arranged on the inner circle of the water inlet hole, one end of the water inlet pipe is located at the lower end of the monitoring ball, a one-way tube 1 is arranged at one end of the water inlet pipe, a water outlet pipe is arranged on the inner wall of the water outlet hole, one end of the water outlet pipe is located inside the cleaning cylinder, and a one-way tube 2 is arranged at one end of the water outlet pipe.

[0015] Furthermore, a plurality of one-way valves are evenly and equidistantly arranged at the lower end of the cleaning cylinder.

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

[0018] Beneficial effects of the present invention:

[0019] 1. By setting a dry cavity and a wet cavity inside the monitoring ball and setting a configuration block inside the wet cavity, the weight of the wet cavity is greater than that of the dry cavity. When the offshore buoy is overturned by the impact of waves, the wet cavity of the monitoring ball rotates along the axis under the action of gravity, and is always automatically adjusted and located at the bottom, ensuring that the detection head is always located inside the seawater, and the signal line is always located above the surface of the seawater, ensuring the normal monitoring of the monitoring ball and improving the stability of the offshore buoy in sea surface monitoring.

[0020] 2. By setting up a cleaning component, the cleaning component can regularly clean the accumulated attachments on the surface of the detection head without human intervention, avoiding the long-term accumulation of attachments on the detection head and affecting the detection data of the detection head, ensuring the normal monitoring of the detection head, reducing the workload of the staff, and improving the accuracy and stability of the monitoring data of the monitoring ball.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] Example 1, reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides an offshore buoy for monitoring nuclear waste water discharge, including a floating ring 1, a mounting ring groove 2 opened on the outer wall of the floating ring 1, a rubber airbag 3 fixedly installed in the mounting ring groove 2, and also includes 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 component includes two mounting blocks 4 fixedly mounted on the inner wall of the floating ring 1, two rotating shafts 5 rotatably mounted on the inner walls of the two mounting blocks 4, a monitoring ball 6 fixedly mounted between the two rotating shafts 5, a partition plate 7 fixedly mounted on the inner wall of the monitoring ball 6, a dry chamber 10 opened inside the monitoring ball 6 and located above the partition plate 7, a wet chamber 11 opened inside the monitoring ball 6 and located below the partition plate 7, and a monitor 12 fixedly mounted on the upper end of the partition plate 7.

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

[0038] Reference Figure 3 and Figure 4The signal transmission component 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 soft antenna. The outer layer of the signal line 15 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 15 is electrically connected to the monitor 12. A counterweight 8 for increasing gravity is fixedly mounted inside the wet chamber 11, and the counterweight 8 is made of lead.

[0039] Specifically, the floating ring 1 and the rubber airbag 3 are both arranged in a circular shape. The floating ring 1 is used to provide support for the monitoring ball 6, and the rubber airbag 3 is used to provide buoyancy for the whole, ensuring that the rubber airbag 3 can always float on the ocean surface with the monitoring ball 6. 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 to prevent floating objects on the sea surface from scratching and damaging the rubber airbag 3 under the impact of waves, causing 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 through the rotating shaft 5. The floating ring 1 can drive the monitoring ball 6 to float on the sea surface through the rubber airbag 3. At the same time, the wet cavity 11 of the monitoring ball 6 is filled with seawater and is equipped with a counterweight 8. The counterweight 8 can make the weight in the wet cavity 11 of the monitoring ball 6 much greater than the weight in the dry cavity 10. This ensures that even if the floating ring 1 is knocked down by waves (i.e. flipped 180°), the monitoring ball 6 can rotate along the rotating shaft 5 due to the deviation of its own gravity, ensuring that 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 sea surface. It can effectively ensure the normal monitoring of the offshore buoy. At the same time, the signal line 15 is an active soft antenna. When the floating ring 1 is overturned, the signal line 15 can bend when the monitoring ball 6 is adjusted and rotated, ensuring that the monitoring ball 6 can rotate and adjust normally. The outer layer of the signal line 15 is wrapped with high-quality plastic. Even if the signal line 15 contacts seawater, the plastic can effectively protect the inside of the signal line 15 from contacting seawater. The plastic has strong aging resistance and certain seawater corrosion resistance, which improves the service life of the signal line 15 and ensures that the offshore buoy can perform monitoring tasks for a long time.

[0041] The dry chamber 10 is used to place the drive device and electronic components. The partition plate 7 separates the dry chamber 10 from the wet chamber 11 to prevent seawater from entering the dry chamber 10 and damaging the internal electronic components and drive devices. 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, reference Figure 1-Figure 3 as well as Figure 6-Figure 10, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the detection assembly 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 disk 20 fixedly installed at the lower end of the extension column 19, the detection head 18 is connected to the monitor 12 signal, a contraction element is installed at the upper end of the sliding cylinder 17, and a cleaning element is installed at the upper end of the cleaning cylinder 16. The contraction element includes a transformer cylinder 21 fixedly mounted on the upper end of the partition plate 7, a hydraulic cylinder 22 fixedly mounted on the upper end of the transformer cylinder 21, a piston plate 23 slidably mounted on the inner wall of the transformer cylinder 21, a piston rod 24 arranged between the piston plate 23 and the telescopic end of the hydraulic cylinder 22, a connecting plate 25 fixedly mounted on the inner wall of the sliding cylinder 17, and a linkage rod 26 fixedly mounted between the lower end of the piston plate 23 and the upper end of the connecting plate 25. The linkage rod 26 is sealed and slidable on the lower end of the transformer cylinder 21 and the middle of the partition plate 7 respectively, and water inlet and outlet parts are installed inside the transformer cylinder 21. The water inlet and outlet parts include a water inlet hole 27 and a water outlet hole 28 opened at the lower end of the transformer cylinder 21, a water inlet pipe 29 fixedly installed on the inner circle of the water inlet hole 27, one end of the water inlet pipe 29 is located at the lower end of the monitoring ball 6, a one-way pipe 1 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 is located inside the cleaning cylinder 16, and a one-way pipe 2 32 fixedly installed at one end of the water outlet pipe 31. A plurality of one-way valves 33 are evenly and equidistantly arranged at the lower end of the cleaning cylinder 16.

[0043] Specifically, by providing the sliding cylinder 17, the connecting plate 25, the piston plate 23 and the 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, the sliding cylinder 17 can be driven to move upward synchronously through the linkage rod 26 and the connecting plate 25. When the sliding cylinder 17 moves upward, it drives the detection head 18 at its lower end to move synchronously, so that the detection head 18 enters the interior of the cleaning cylinder 16, so that the detection head 18 is cleaned inside the cleaning cylinder 16. At the same time, when the detection head 18 slides upward into the interior of the monitoring ball 6, the piston plate 23 moves upward, and the pressure inside the transformer cylinder 21 decreases. At this time, the external seawater enters the transformer cylinder 21 through the one-way pipe 30 and the water inlet pipe 29 under the action of pressure for storage. When the detection head 18 completes cleaning, the detection head 18 will move downward under the action of the linkage rod 26, and the piston plate 23 moves downward at the same time. When the piston plate 23 moves downward, the previously collected seawater is injected into the cleaning cylinder 16 through 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 inside the cleaning cylinder 16 is mixed with attachments and is discharged into the sea through the one-way valve 33 under the action of pressure, which can effectively avoid the presence of a large number of attachments in the cleaning cylinder 16 and affect the subsequent cleaning work.

[0044] The water inlet and outlet directions of the one-way tube 1 30 and the one-way tube 2 32 are opposite. The one-way tube 1 30 can only take in water but not discharge water, while the one-way tube 2 32 can only discharge water but not take in water. The function of the extension column 19 and the sealing rubber disc 20 is to ensure that the circular groove is in a sealed state when the detection head 18 enters the interior of the cleaning cylinder 16, that is, through the mutual cooperation of the extension column 19 and the sealing rubber disc 20, the detection head 18 can completely enter the interior of the cleaning cylinder 16 for cleaning, and 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 structures are the same as those of Example 1.

[0046] Example 3, reference Figure 5-Figure 7, which is the third embodiment of the present invention, and this embodiment is different 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 synchronizer ring 35 fixedly mounted on the inner wall of the rotating gear ring 34, a plurality of rotating plates 36 evenly and equidistantly fixedly mounted on the lower end of the synchronizer ring 35 with the center of the synchronizer ring 35 as the axis, a brush rod 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 are respectively meshed 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, the two driving gears 9 are used to drive the rotating gear ring 34 to rotate. The rotation of the rotating gear ring 34 drives the brush rod 37 to rotate synchronously. A soft brush is installed on the side wall of the brush rod 37. The rotating brush can clean the attachments on the surface of the detection head 18, remove the attachments, and cooperate with the water inlet and outlet parts to flush the cleaned attachments back into the sea, completing the cleaning of the attachments on the surface of the detection head 18. Regular cleaning can ensure the normal monitoring of the detection head 18 and avoid the attachments affecting the normal monitoring of the detection head 18, resulting in inaccurate monitoring data. The servo motor 38 is located inside the dry cavity 10, which can effectively prevent the servo motor 38 from contacting with seawater and causing damage to the servo motor 38, effectively improving the service life of the device. And cleaning the detection head 18 does not require manual participation, which greatly reduces the workload and maintenance work of the staff.

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

[0049] Based on Examples 1-3, the working principle of the present invention is as follows: the staff turns on the monitor 12 and places the offshore buoy in the designated sea area. Since 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 with the shaft 5, so that the wet cavity 11 is located below (i.e., inside the seawater), the detection head 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 detection head 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 back end. When the offshore buoy is overturned by the impact of waves (deflected 180°), even if the floating ring 1 flips 180°, the monitoring ball 6 still deflects and adjusts left and right due to the uneven mass, so that the wet cavity 11 and the detection head 18 at the lower end are located inside the seawater again and monitor, and the signal line 15 transmits the signal above the seawater surface.

[0050] When the detection head 18 is located in the seawater for monitoring for a certain period of time, the hydraulic cylinder 22 and the two servo motors 38 are turned on under the control of the background, and the telescopic end of the hydraulic cylinder 22 moves upward, and then drives the piston plate 23 upward through the piston rod 24. During the upward movement of the piston plate 23, the sliding cylinder 17 is driven to move upward synchronously through the linkage rod 26, so that the sliding cylinder 17 drives the detection head 18 to enter the cleaning cylinder 16 to prepare for cleaning. At the same time, during the upward movement of the piston plate 23, the seawater around the monitoring ball 6 is sucked into the transformer cylinder 21 for storage. When the detection head 18 enters the cleaning cylinder 16, the inside of the transformer cylinder 21 is filled with seawater for storage.

[0051] When the detection head 18 enters the cleaning cylinder 16, the two servo motors 38 are started to drive the corresponding rotating rods 39 to rotate through the driving ends. The rotation of the rotating rods 39 drives the corresponding driving gears 9 to rotate synchronously. The two driving gears 9 rotate in opposite directions to each other, and jointly 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 detection head 18 and cleans the attachments on the surface of the detection head 18 to ensure the cleanliness of the surface of the detection head 18.

[0052] After the cleaning is completed, the telescopic end of the hydraulic cylinder 22 drives the piston rod 24 to move downward, and at the same time drives the piston plate 23, the linkage rod 26, the sliding cylinder 17 and the detection head 18 to move downward, so that the detection head 18 extends back into the ocean to continue monitoring the internal area of ​​the ocean. At the same time, when the piston plate 23 moves downward, the piston plate 23 presses out the seawater inside the transformer cylinder 21, and enters the cleaning cylinder 16 through the one-way pipe 2 32 on the outlet pipe 31. The seawater enters the cleaning cylinder 16, which increases the pressure inside the cleaning cylinder 16. Under the action of the pressure, the seawater inside the cleaning cylinder 16 rushes out of the monitoring ball 6 through the one-way valve 33, avoiding the presence of many attachments inside the monitoring ball 6 that affect the subsequent cleaning work. That is, when the detection head 18 moves out of the cleaning cylinder 16, the seawater stored in the transformer cylinder 21 is discharged synchronously, and the cleaned attachments are discharged from the cleaning cylinder 16 synchronously.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
