Description

Technical Field

[0001] This invention relates to the field of nuclear power safety technology, and in particular to an integrated multi-parameter environmental sensing nuclear power cold source disaster biological monitoring device. Background Technology

[0002] At present, ecological disasters frequently occur at the cold source water intake of the nuclear reactor cooling system of the coastal nuclear power plant. Marine organisms such as jellyfish and sea cucumbers gather in large numbers at the water intake pipes and cooling system inlets, which leads to a decrease in cooling water flow rate, a reduction in heat exchange efficiency, and even causes reactor cooling system failures, seriously threatening the safe operation of nuclear power units and the effectiveness of nuclear emergency protection systems.

[0003] Currently, marine life monitoring devices use multispectral cameras for biological imaging and identification. However, these devices rely solely on optical cameras and lack acoustic detection. This leads to imaging failure in turbid water, making it impossible to detect transparent organisms (such as jellyfish) and nocturnal creatures. For example, Chinese patent CN117804533A discloses a smart marine cetacean monitoring buoy and its control system. This buoy includes a float equipped with optical acquisition components, acoustic acquisition components, marine environment acquisition components, signal transmission components, and a power supply component. The power supply component provides power to these components. In operation, the optical and acoustic acquisition components collect signals from cetaceans in the ocean, while the marine environment acquisition component collects data about the surrounding marine environment. The signal transmission component transmits the collected marine environmental data and cetacean signals. This acoustic detection passively receives acoustic signals and cannot actively detect large mammals. This application balances the capabilities of offshore power supply, data processing, and offshore data transmission, enabling a wider monitoring range, longer monitoring time, and lower monitoring investment, which is more conducive to assessing the diversity characteristics of deep-sea biological resources, such as population distribution and spatiotemporal evolution.

[0004] Based on the comparative documents and analysis of existing technologies, the problem disclosure reveals a wide variety of marine pests, and a lack of early warning and monitoring for outbreaks of emerging pests such as krill, jellyfish, and sea cucumbers. Furthermore, the possibility and risk of future outbreaks of other marine organisms causing harm cannot be ruled out. Currently, relying on manual sampling or fixed sensors makes it difficult to achieve real-time dynamic monitoring of marine pests, hindering early intervention and warning. Summary of the Invention

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] According to one embodiment of the present invention, Figures 1-7 As shown. Example 1

[0021] An integrated multi-parameter environmental sensing nuclear power plant cold source disaster biological monitoring device includes a monitoring float 11. The outer surface of the monitoring float 11 is provided with a movable groove 13, which connects to a fixed structure surrounding the water intake of the nuclear power plant cold source cooling system. A clamping ring 12 is installed on the outer surface of the monitoring float 11, and the clamping ring 12 is embedded inside the movable groove 13. An anchor chain 14 is connected to the edge of the clamping ring 12, and a bottom ball 15 is connected to the bottom end of the anchor chain 14. The bottom end of the bottom ball 15 is provided with... Anchor hooks 16 and bottom balls 15 are used to fix the monitoring float 11 to the liquid. A positioning ring 17 is fixedly connected to the outer wall of the clamp ring 12. Anchor chains 14 penetrate vertically downward through the interior of the positioning ring 17. Eight sets of anchor chains 14 are evenly distributed around the clamp ring 12. Each set of anchor chains 14 is equipped with a bottom ball 15 at the bottom end. Only four sets of bottom balls 15 are equipped with anchor hooks 16 at the bottom end. The anchor chains 14, bottom balls 15 and anchor hooks 16 face different directions.

[0022] To ensure the monitoring device can be better secured in the corresponding sea area, a bottom ball 15 and an anchor hook 16 are used for fixation. By sinking the bottom ball 15 and anchor hook 16 into the seawater, the clamp ring 12 remains floating on the water surface. At this time, the bottom ball 15 and anchor hook 16 are positioned on the riverbed to pull the clamp ring 12, thereby restricting the position of the clamp ring 12. By pulling in eight different directions, the impact of seawater fluctuations on the clamp ring 12 can be reduced. Then, the monitoring float 11 is embedded into the interior of the clamp ring 12. When the left side of the clamp ring 12... With the rightward sway reduced, the impact on the monitoring float 11 is also reduced. To adapt to the ups and downs of the seawater, the monitoring float 11 and the clamp ring 12 are connected by a movable groove 13, which makes the monitoring float 11 and the clamp ring 12 in a sliding connection relationship. At this time, the ups and downs of the seawater allow the monitoring float 11 to make adaptive changes. The traction of the bottom ball 15 and the anchor hook 16 can reduce the left and right sway of the clamp ring 12, increasing the stability of the monitoring float 11. Monitoring on this basis can improve the accuracy of monitoring.

[0023] Real-time monitoring of organisms is accomplished through monitoring component 2, and the specific operation is as follows: A balancing component 3 is installed inside the monitoring float 11. The balancing component 3 includes a housing 31. The housing 31 is embedded inside the monitoring float 11. A support plate 32 is connected to the bottom of the housing 31. The monitoring component 2 is installed on the upper surface of the support plate 32. The monitoring component 2 includes a monitoring shell 21. The monitoring shell 21 is embedded inside the support plate 32. A light stand 22 is connected to the top of the monitoring shell 21. A solar panel 23 is connected to the top of the light stand 22. A camera 24 is also installed on the light stand 22. A broadband fish finder 25 is embedded inside the monitoring shell 21. A tailpipe 26 is connected to the bottom of the monitoring shell 21. A power supply system is installed inside the monitoring shell 21. The monitoring shell 21 has a battery compartment designed to accommodate a battery. A space is reserved in the middle of the tailpipe 26 to fix an underwater camera. The sonar probe installed in the monitoring component 2 can detect organisms from different directions.

[0024] This monitoring device utilizes a comprehensive and specific intelligent online monitoring system, incorporating a wideband fish finder 25, a multi-parameter water quality instrument, surface and underwater video equipment, and an ocean current profiler, to conduct real-time dynamic and continuous monitoring of risky organisms and ocean currents in the waters surrounding nuclear power plant cold sources. This enables early intervention and prevention, enhancing the initiative and effectiveness of cold source ecological disaster prevention and providing technical support for nuclear power plants to effectively respond to the threat of marine biological invasion. This effectively ensures the safety of water intake for nuclear power plant cold sources. Acoustic technology is employed for marine organism detection, with three sonar probes deployed vertically and in two horizontal directions to detect marine organisms from different angles, covering as many potential hazards as possible at the nuclear power plant's water intake. It can also detect smaller individuals such as shrimp and transparent organisms like jellyfish, and the species can be verified using an underwater camera.

[0025] The monitoring equipment is diverse and powerful, especially the wideband fish finder 25, which has three sonar probes and high power. It is designed with a large-capacity power supply system. The monitoring housing 21 has a battery compartment that can accommodate ten batteries, each with a capacity of 120AH. It is also equipped with solar panels 23, each with a power of 160W. These solar panels can provide power to the wideband fish finder 25, multi-parameter water quality meter, surface and underwater video monitoring system, Doppler current profiler, weather station, positioning device, and other equipment. This allows the equipment to conduct uninterrupted monitoring of disaster-causing biological risks and environmental perception of the surface and underwater environment for 7 days, even in extreme rainy weather conditions.

[0026] The monitoring device mainly consists of three parts: the monitoring housing 21, the light holder 22, and the tailpipe 26. The monitoring housing 21 is equipped with instrument wells, including wells for setting up instruments, multi-parameter water quality instruments, Doppler current profilers, and broadband fish finders in both horizontal and vertical directions. Each instrument is fixed inside the monitoring housing 21 via a track in its instrument well. A disc is fixed to the surface of the monitoring housing 21 above the instrument holder. For instrument maintenance, simply unscrewing the fixing screws on the disc allows the instrument holder and instruments to be removed via the track in the instrument well, facilitating maintenance and upkeep. The monitoring housing 21 houses the power supply system and includes a battery compartment that can accommodate 120AH batteries. The tailpipe 26 is a cylinder constructed of stainless steel and cement, increasing the stability of the monitoring device. A space is reserved in the middle of the tailpipe 26 to secure an underwater camera. The light holder 22 houses an electronic control box in its middle section, which can accommodate two transceivers for the broadband scientific fish finder, an industrial computer, and the monitoring device's main data control system. The top of the light frame 22 can be used to fix a water camera, a Beidou positioning device and a radar reflector. The top is equipped with a weather station, a lightning rod, a navigation light and an AIS system. The top outer frame of the light frame 22 is circular and has four rectangular slots for directly fixing solar panels 23.

[0027] Based on the effective suppression of horizontal sway through the anchoring system and the offsetting of vertical fluctuations through the differential design, the synergistic effect of the monitoring float 11, the containment tank 31, and the balancing ring 36 further constructs a multi-dimensional stabilization mechanism, creating a more stable working environment for the monitoring equipment. The monitoring float 11 achieves a stable semi-floating, semi-submerged posture thanks to its special material distribution, and its enveloping structure on the containment tank 31 buffers direct impacts from the sea surface. Meanwhile, the linkage design between the balancing ring 36 and the transmission mechanism further weakens residual sway through mechanical compensation. The organic combination of these components not only elevates the stability of the monitoring device to a new level but also lays a solid foundation for the high-precision operation of monitoring component 2. The following section elaborates on its specific structure and working principle, detailing how it provides precise assurance for monitoring biological hazards caused by nuclear power plant cold sources.

[0028] A balance ring 36 is fixedly connected to the outer wall of the receiving chamber 31, and the receiving chamber 31 is embedded inside the balance ring 36. A second rack 37 is fixedly connected to the outer wall of the balance ring 36, and the second rack 37 is vertically arranged on the balance ring 36. The balance ring 36 is embedded inside the monitoring float 11. A first rack 33 is fixedly connected to the inner wall of the monitoring float 11, and the first rack 33 is vertically downward arranged on the inner wall of the monitoring float 11. There are four sets of racks on the inner wall of the monitoring float 11. A transmission gear 35 meshes between the first rack 33 and the second rack 37. A suspension rod 34 is embedded inside the transmission gear 35. The suspension rod 34 is arranged on the clamp ring 12 and fixes the transmission gear 35 between the first rack 33 and the second rack 37. The clamping teeth on the first rack 33 and the second rack 37 are arranged opposite each other. The receiving chamber 31 is arranged inside the monitoring float 11 through the first rack 33, the suspension rod 34, the transmission gear 35 and the second rack 37.

[0029] To improve stability, the detection device is placed on the sea surface and positioned using the sinker ball 15 and anchor hook 16. Since the monitoring float 11 has a cylindrical structure, when the monitoring device is placed on the sea surface, the upper half of the monitoring float 11 floats above the water, while the lower half sinks below the surface. This is because the upper and lower halves of the monitoring float 11 are made of different materials; the upper half has a lower density than seawater, while the lower half has a higher density. This ensures that half of the monitoring float 11 floats on the surface and the other half sinks to the bottom. Since the receiving chamber 31 is located inside the monitoring float 11, the monitoring float 11 can be used to enclose the receiving chamber 31. When the seawater fluctuates, the enclosure of the receiving chamber 31 by the monitoring float 11 can block the surface fluctuations. The clamp ring 12 is pulled by the anchor chain 14, sinker ball 15, and anchor hook 16, reducing horizontal sway and thus reducing the swaying of the inner monitoring float 11 and receiving chamber 31; ultimately reducing... The monitoring buoy 11 is affected by the fluctuations of seawater. When the monitoring buoy 11 is subjected to vertical fluctuations, it continuously rises and falls. When the monitoring buoy 11 rises, it drives the first rack 33 to rise. After the first rack 33 rises, it drives the transmission gear 35 to rotate. When the transmission gear 35 rotates, it transmits the force to the second rack 37. At this time, the second rack 37 will move in the opposite direction to the first rack 33. That is, when the first rack 33 rises, the second rack 37 falls. When the second rack 37 falls, it drives the balance ring 36 to fall. When the balance ring 36 falls, it drives the monitoring buoy 31 and the monitoring component 2 installed inside the monitoring buoy 31 to fall. Through the reverse movement design of the monitoring buoy 11 and the monitoring buoy 31, the energy of the up and down fluctuations of seawater can be effectively offset. When the monitoring float 11 rises with the waves, the containment chamber 31 descends, and vice versa. This differential motion significantly reduces the overall vertical sway of the monitoring device, providing a more stable working platform. As the sway of the monitoring component 2 on the containment chamber 31 decreases, its data acquisition becomes more accurate. For example, when measuring seawater temperature, salinity, or pollutant concentration, a stable posture avoids sensor mis-triggering or data deviation caused by swaying, improving the reliability of marine monitoring. Secondly, the transmission mechanism composed of the first rack 33, the transmission gear 35, and the second rack 37 converts some of the kinetic energy of the seawater fluctuations into the power for the reverse movement of the containment chamber 31, reducing external energy consumption. Furthermore, this passive compensation mechanism has a fast response speed and can handle waves of different frequencies in real time.

[0030] An isolation component 4 is fixedly connected to the bottom of the receiving chamber 31. The isolation component 4 includes a partition column 41. A connecting ring 43 is connected to the bottom of the partition column 41. An isolation rod 42 is also provided inside the partition column 41. The isolation rod 42 is embedded between two sets of partition columns 41. The isolation rod 42 and the partition column 41 are rotatably connected. The isolation rod 42 is used to isolate impurities in the liquid.

[0031] According to another embodiment of the invention, Figure 1 , Figure 8 and Figure 9 As shown. Example 2

[0032] An integrated multi-parameter environmental sensing bio-monitoring device for nuclear power plant cold source disasters includes a monitoring float 11. The outer surface of the monitoring float 11 is provided with a movable groove 13. A clamping ring 12 is installed on the outer surface of the monitoring float 11, and the clamping ring 12 is embedded inside the movable groove 13. An anchor chain 14 is connected to the edge of the clamping ring 12, and a bottom ball 15 is connected to the bottom end of the anchor chain 14. An anchor hook 16 is provided at the bottom end of the bottom ball 15. The bottom ball 15 and the anchor hook 16 are used to fix the monitoring float 11 into the liquid. A positioning ring 17 is fixedly connected to the outer wall of the clamping ring 12, and the anchor chain 14 penetrates vertically downwards through the interior of the positioning ring 17. Eight sets of anchor chains 14 are evenly distributed around the clamping ring 12, and each set of anchor chains 14 has a bottom ball 15 at its bottom end. Only four sets of bottom balls 15 have anchor hooks 16 at their bottom ends. The anchor chains 14, bottom balls 15, and anchor hooks 16 face different directions to restrict the position of the bio-monitoring device.

[0033] The monitoring float 11 is equipped with a balancing component 3, which includes a housing 31. The housing 31 is embedded inside the monitoring float 11. A support plate 32 is connected to the bottom of the housing 31. A monitoring component 2 is installed on the upper surface of the support plate 32. The monitoring component 2 includes a monitoring shell 21. The monitoring shell 21 is embedded inside the support plate 32. A light stand 22 is connected to the top of the monitoring shell 21. A solar panel 23 is connected to the top of the light stand 22. A camera 24 is also installed on the light stand 22. A broadband fish finder 25 is embedded inside the monitoring shell 21. A tailpipe 26 is connected to the bottom of the monitoring shell 21. A power supply system is installed inside the monitoring shell 21. The monitoring shell 21 has a battery compartment designed to accommodate a battery. A space is reserved in the middle of the tailpipe 26 to fix an underwater camera. The sonar probe installed in the monitoring component 2 can detect organisms from different directions.

[0034] The inner wall of the receiving chamber 31 is connected to a connecting roller, and a shock absorber 39 is connected to one side of the connecting roller. The shock absorber 39 is embedded in the interior of the buffer groove 38. The buffer groove 38 is set on the outer wall of the receiving chamber 31. Four sets of shock absorbers 39 are evenly spaced on the outer wall of the receiving chamber 31. Slide grooves are opened on the left and right sides of the shock absorber 39, and another set of slide grooves is opened on the front side. The connecting roller passes through the slide groove on the front side and is fixedly connected to the shock absorber 39. The connecting roller extends out from the slide grooves on the left and right sides.

[0035] An isolation component 4 is fixedly connected to the bottom of the receiving chamber 31. The isolation component 4 includes a partition column 41. A connecting ring 43 is connected to the bottom of the partition column 41. An isolation rod 42 is also provided inside the partition column 41. The isolation rod 42 is embedded between two sets of partition columns 41. The isolation rod 42 and the partition column 41 are rotatably connected. The isolation rod 42 is used to isolate impurities in the liquid.

[0036] Another monitoring device proposed in this invention operates as follows: The monitoring system is fixed to the sea area by an anchoring system consisting of eight sets of anchor chains 14, bottom balls 15, and anchor hooks 16. Four sets of bottom balls 15 have anchor hooks 16 at their bottom ends for anchoring to the riverbed. The traction in eight directions effectively reduces the horizontal swaying of the clamp ring 12. Additionally, a monitoring float 11 is nested inside the clamp ring 12 and slidably connected via a movable groove 13 to adapt to the up-and-down fluctuations of the seawater. The upper half of the monitoring float 11 has a lower density than seawater, while the lower half has a higher density, resulting in a semi-floating, semi-submerged state. Combined with the anchoring system, this further enhances stability. The containment chamber 31 houses the monitoring system 2, including a multi-directional sonar probe, a multi-parameter water quality instrument, and an underwater camera. High-precision real-time monitoring is achieved through a stable platform. The sonar probe covers vertical and two horizontal directions, capable of detecting tiny and transparent organisms. The camera operates 24 hours a day without interruption. To further enhance the stability of the containment chamber 31, the device employs a linkage design between a shock absorber 39 and a buffer groove 38. When the monitoring float 11 sways vertically due to the impact of waves, the connecting rollers on its inner wall push the shock absorber 39 into the buffer tank 38. Under the impact force, the shock absorber 39 undergoes elastic deformation, converting kinetic energy into stored elastic potential energy. When the external force weakens, the shock absorber 39 quickly resets and releases the stored elastic potential energy. The released energy acts in the opposite direction to the monitoring float 11, forming a damping force opposite to the swaying direction. Through this dynamic buffering mechanism of repeated compression and energy storage and expansion within the buffer tank 38, the swaying energy transmitted from the monitoring float 11 to the containment tank 31 is significantly attenuated. This design effectively suppresses the vibration amplitude of the containment tank 31, providing a more stable operating foundation for the mounted broadband fish finder 25, multi-parameter water quality instrument, and other monitoring equipment, thereby ensuring the accuracy of data acquisition and enabling the monitoring results to more accurately reflect the biological and environmental conditions of the sea area surrounding the nuclear power plant cold source.

[0037] The power supply system combines solar panels 23 and batteries to ensure continuous operation of the equipment. The rotating structure of the partition column 41 and isolation rod 42 of the isolation component 4 can isolate impurities in the water and protect the monitoring equipment, thereby realizing dynamic monitoring and environmental perception of harmful organisms in the sea area surrounding the nuclear power plant cold source.

[0038] The isolation component 4 features an innovative rotating structure design for its separator column 41 and isolation rod 42, effectively addressing interference from impurities in complex seawater. The separator column 41 is vertically fixed to the bottom of the monitoring device, with a rotatable isolation rod 42 embedded inside. The two are connected by bearings for flexible rotation. When seawater flow carries impurities (such as algae and suspended matter) close to the monitoring equipment, the isolation rod 42 automatically rotates under the impact of the water flow, forming a dynamic barrier that intercepts the impurities. This rotating design prevents impurities from adhering to and clogging sensors or cameras, while also reducing mechanical resistance and ensuring normal water flow. Furthermore, the streamlined shape of the isolation rod 42 further optimizes hydrodynamic performance, reducing interference with monitoring data. This isolation structure requires no additional energy drive, relying entirely on the natural action of water flow for self-cleaning, significantly improving the device's anti-interference capability and long-term stability, and ensuring the accuracy of acoustic detection and environmental perception.
