Description

Technical Field

[0001] This utility model relates to the technical field of remote monitoring devices for cold sources in nuclear power plants, and in particular to a remote patrol device for cold sources in nuclear power plants. Background Technology

[0002] Nuclear power, as a crucial component of clean energy, has always been a subject of great concern regarding its safety. The cooling system of a nuclear power plant, particularly the intake water, is a critical link in ensuring the plant's normal operation. The stability and reliability of the cooling water quality directly impact the safety and economic viability of the nuclear power plant. Therefore, continuous and effective monitoring of the marine area supplying nuclear power plant cooling water is of paramount importance.

[0003] The impact of nearshore organisms and foreign objects on the safety of nuclear power plant cooling sources is a global challenge facing coastal nuclear power plants both domestically and internationally. According to incomplete statistics from the World Association of Nuclear Operators (WANO), since 2004, there have been hundreds of cooling source incidents at nuclear power plants worldwide. Large-scale outbreaks of nearshore organisms, such as algae, jellyfish, and krill, can clog intakes or filtration systems at pumping stations, leading to insufficient cooling water supply and consequently affecting the safe operation of the nuclear power plant.

[0004] With the rapid development of unmanned technology, unmanned surface vessels (USVs), as a new type of surface robot, are widely used in the field of marine monitoring. USVs are equipped with various biological detection devices, such as sonar, underwater cameras, and in-situ plankton imagers, enabling them to autonomously navigate to the sea areas near nuclear power plant cold sources for continuous and efficient monitoring. However, the monitoring range of components in USVs used for detecting aquatic life is limited, making it difficult to meet the demands of their application. Utility Model Content

Therefore, this utility model is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0050] See Figures 1 to 5This utility model provides a remote patrol device for a nuclear power plant cold source, used for monitoring aquatic organisms at the remote end of the nuclear power plant cold source. The remote patrol device includes a hull 100, a launch and recovery frame 200, and a patrol component 300. The hull 100 is remotely controlled to travel on the sea surface. The launch and recovery frame 200 is movably connected to the hull 100, and the distance from the end of the launch and recovery frame 200 away from the hull 100 to the hull 100 is adjustable. The end of the launch and recovery frame 200 away from the hull 100 extends into the seawater. The patrol component 300 is located at the end of the launch and recovery frame 200 away from the hull 100 and is used to monitor aquatic organisms in the seawater.

[0051] This technical solution provides a remote patrol device for nuclear power plant cold sources, used for monitoring aquatic life at the remote end of the nuclear power plant cold source. Specifically, the remote patrol device includes a hull 100, a deployment and recovery frame 200, and patrol components 300. The hull 100 is an unmanned vessel that is remotely controlled to navigate on the sea surface, thereby driving the deployment and recovery frame 200 and the patrol components 300 to move in the waters at the remote end of the nuclear power plant cold source. By movably connecting the deployment and recovery frame 200 to the hull 100, the distance between the end of the deployment and recovery frame 200 away from the hull 100, i.e., the end located in the seawater, and the hull 100 is adjustable. Since the cruise component 300 is located at the end of the launch and recovery frame 200 away from the hull 100, the distance between the cruise component 300 and the hull 100 is adjustable. This allows the cruise component 300 to adjust its depth in the seawater according to monitoring needs, thereby making the monitoring range of the remote cruise device for nuclear power plant cold sources wider, meeting the usage needs of different scenarios, and making the monitoring more accurate and reliable.

[0052] In this embodiment, the underwater environment and aquatic organism distribution around the hull 100 are dynamically monitored and analyzed by the cruise component 300. By mounting the cruise component 300 on the unmanned hull 100, it can autonomously navigate to the nuclear power plant's cooling source area for continuous and efficient monitoring, promptly detecting marine biological invasion events and ensuring the safety and economy of the nuclear power plant's operation.

[0053] like Figure 5 As shown, in one embodiment, the cruise component 300 includes an underwater camera 320, a sonar 310, and an in-situ plankton imager 330. The underwater camera 320 is located on the side of the bottom of the launch and recovery frame 200 facing the direction of travel; the sonar 310 is located on the side of the bottom of the launch and recovery frame 200 facing the direction of travel and is adjacent to the underwater camera 320; the in-situ plankton imager 330 is located at the bottom of the launch and recovery frame 200.

[0054] Specifically, the underwater camera 320 provides high-definition real-time video footage, enabling clear observation of underwater biological activities, equipment status, and special phenomena in cold source areas, such as cold seep eruptions and hydrothermal activity. Operators can intuitively understand the underwater situation through video and obtain data that cannot be directly measured by other equipment, such as biological behavior and habits, and details of the surrounding environment of the cold source, providing researchers with rich image data for in-depth study of cold source ecosystems.

[0055] The sonar 310, mounted on the manned hull 100, can acquire underwater topographic data and obstacle distribution information by emitting sound waves and receiving reflected signals. In the complex underwater environment of the cold source area, the sonar 310 can detect the location and shape of obstacles such as reefs and shipwrecks, generate high-precision three-dimensional underwater maps, and conduct long-term monitoring of seabed topographic changes in the cold source area to promptly detect topographic evolution trends.

[0056] The In-situ Plankton Imager 330 employs high-resolution imaging technology to acquire real-time data on plankton species, quantity, and distribution density. In cold source ecological monitoring, this data can directly reflect the health status of the ecosystem. For example, by analyzing changes in plankton community structure, the impact of water quality changes and nutrient concentration fluctuations in cold source areas on the ecosystem can be determined, providing scientific data support for ecological protection and restoration.

[0057] The forward-looking sonar 310 stores the real-time monitored information in the industrial control computer carried by the unmanned vessel. The operator can remotely view the real-time images of the underwater camera 320 through the unmanned vessel base station software, and use the in-situ plankton imager 330 to obtain high-resolution biological images, so as to dynamically monitor and analyze the underwater environment and plankton distribution during the operation.

[0058] like Figure 2 As shown, in one embodiment, the launch and recovery rack 200 includes a fixed base 210 and an adjusting member 220. The fixed base 210 is connected to the hull 100; the adjusting member 220 is connected to the fixed base 210 and is operablely movable relative to the fixed base 210 so that the distance between the end of the adjusting member 220 away from the fixed base 210 and the hull 100 is adjustable; wherein, the cruise component 300 is connected to the end of the adjusting member 220 away from the fixed base 210.

[0059] In this embodiment, by fixing the fixed base 210 to the hull 100 and connecting the adjusting member 220 to the fixed base 210, the adjusting member 220 is operablely movable relative to the fixed base 210. This allows the distance between the end of the adjusting member 220 away from the fixed base 210 and the hull 100 to be adjustable. Consequently, the distance between the cruise component 300 connected to the adjusting member 220 and the hull 100 is adjustable. This allows the cruise component 300 to adjust its depth in the seawater according to monitoring requirements, thereby making the monitoring range of the remote cruise device for the nuclear power plant cold source wider and the monitoring more accurate and reliable.

[0060] Specifically, the fixed base 210 has multiple guide holes, which are spaced apart; the adjusting member 220 includes multiple guide rods 221, which correspond to the guide holes and are guided by the guide holes.

[0061] By providing multiple guide holes on the fixed base 210 and multiple guide rods 221 on the adjusting member 220, and by guiding the guide rods 221 to engage with the guide holes, the guide rods 221 can move relative to the fixed base 210 along the guide holes, thereby adjusting the distance between the end of the guide rod 221 away from the fixed base 210 and the hull 100. Furthermore, by providing multiple spaced guide holes on the fixed base 210, with the guide rods 221 corresponding to the guide holes, the stability and reliability of the movement of the adjusting member 220 relative to the fixed base 210 are improved, resulting in a smoother and more reliable movement of the cruise component 300 relative to the hull 100.

[0062] like Figure 2 As shown, in one embodiment, the fixing base 210 includes two support members 211 and multiple conduits 212, with the two support members 211 spaced apart; the multiple conduits 212 are all connected between the two support members 211, with the multiple conduits 212 spaced apart, and the inner hole of the conduit 212 is a guide hole.

[0063] Specifically, the support member 211 is a frame structure formed by connecting multiple square tubes end to end. The frame structure can be triangular, rectangular, square, etc. In this embodiment, the frame structure is a square structure. Two square frame structures are spaced apart along the depth direction of the hull 100. The conduit 212 can be a square tube or a round tube; in this embodiment, the conduit 212 is a round tube. Four conduits 212 are respectively located at the four corners of the square frame structure.

[0064] Specifically, the conduit 212 and the support member 211 can be fixedly connected by bolts or by welding. The conduit 212 and the two support members 211 form a cuboid frame, which is fixedly connected to the deck of the hull 100.

[0065] like Figure 3 As shown, the mounting base 210 further includes multiple fasteners 213, each fastener 213 being disposed on the support member 211 and spaced apart, and each fastener 213 being used for fixed connection with the hull 100. By fixing multiple fasteners 213 to the support member 211, the mounting base 210 is fixedly connected to the hull 100 by fixing the fasteners 213 to the hull 100.

[0066] Specifically, the fastener 213 includes a fixing plate 2131 and a connecting plate 2132. The fixing plate 2131 is fixedly connected to the support 211 and / or the conduit 212 by welding or bolts. The connecting plate 2132 is constructed in a roughly "L" shape. One end of the connecting plate 2132 is fixedly connected to the fixing plate 2131 by bolts, and the other end of the connecting plate 2132 is provided with two spaced-apart oblong holes through which bolts pass to fix the fastener to the hull 100. Through the above structural form, the fastener 213 is fixedly connected to the hull 100, thereby achieving the fixed connection between the fixing seat 210 and the hull 100.

[0067] like Figure 2 As shown, in one embodiment, the adjusting member 220 further includes a plurality of first connecting members 222 and a plurality of second connecting members 223. Each first connecting member 222 is disposed between two adjacent guide rods 221 and located at the end of the guide rod 221 near the hull 100. The two ends of each first connecting member 222 are respectively fixedly connected to the two adjacent guide rods 221. Each second connecting member 223 is disposed between two adjacent guide rods 221 and located at the end of the guide rod 221 away from the hull 100. The two ends of each second connecting member 223 are respectively fixedly connected to the two adjacent guide rods 221.

[0068] In this embodiment, a first connector 222 is provided between two adjacent guide rods 221, and the first connector 222 is located at the end of the guide rod 221 near the hull 100, so that the end of the guide rod 221 near the hull 100 is fixedly connected through the first connector 222. Correspondingly, a second connector 223 is provided between two adjacent guide rods 221, and the second connector 223 is located at the end of the guide rod 221 away from the hull 100, so that the end of the guide rod 221 away from the hull 100 is fixedly connected through the second connector 223. This arrangement improves the strength of the guide rods 221 while facilitating the movement of multiple guide rods 221 relative to the fixed seat 210.

[0069] Specifically, the guide rod 221 is a circular rod-shaped component, and the guide rod 221 can be made of stainless steel. The first connector 222 and the second connector 223 are both circular rod-shaped components, and similarly, the first connector 222 and the second connector 223 can both be made of stainless steel.

[0070] The number of first connector 222 and second connector 223 can be two or four. When the number of first connector 222 and second connector 223 is two, the following structure can be adopted.

[0071] like Figure 2 As shown, in one embodiment, the adjusting member 220 further includes two first reinforcing members 224 and a second reinforcing member 225. The two first reinforcing members 224 are respectively disposed at both ends of the guide rod 221. The two ends of one first reinforcing member 224 are respectively connected to two oppositely disposed first connecting members 222, and the two ends of the other first reinforcing member 224 are respectively connected to two oppositely disposed second connecting members 223. The second reinforcing member 225 is disposed between the two first reinforcing members 224, and the two ends of the second reinforcing member 225 are respectively fixedly connected to the two first reinforcing members 224.

[0072] Specifically, both the first connector 222 and the second connector 223 are circular stainless steel tubes. There are two first connectors 222, spaced apart, with each end fixedly connected to two adjacent guide rods 221. The two ends of the first reinforcing member 224 are fixedly connected to the middle portions of the two first connectors 222. The two first connectors 222 and the first reinforcing member 224 form an "I"-shaped structure. Similarly, there are two second connectors 223, spaced apart, with each end fixedly connected to two adjacent guide rods 221. The two ends of the first reinforcing member 224 are fixedly connected to the middle portions of the two second connectors 223. The two second connectors 223 and the first reinforcing member 224 form an "I"-shaped structure. In another embodiment, four second connectors 223 can be provided, connected end-to-end to form a square frame, with the four guide rods 221 fixedly connected to the four corners of the square frame. The entire structure of the adjusting member 220 is strengthened by connecting both ends of the second reinforcing member 225 to the two first reinforcing members 224 respectively. In this embodiment, the first reinforcing members 224 and the second reinforcing members 225 are angle steel structures. In another embodiment, the first reinforcing members 224 and the second reinforcing members 225 can also be set as circular tube structures.

[0073] like Figure 2 and Figure 4As shown, in one embodiment, the take-up rack 200 further includes a plurality of locking members 400, each of which corresponds to a guide rod 221. Each locking member 400 is detachably connected to one end of the guide rod 221 near the fixed base 210. The locking member 400 abuts against the fixed base 210 to restrict the movement of the guide rod 221 relative to the fixed base 210.

[0074] By providing a locking element 400 at one end of the guide rod 221 near the fixed base 210, after the relative positions of the guide rod 221 and the fixed base 210 are adjusted, the locking element 400 locks the position between the guide rod 221 and the fixed base 210, thereby allowing the cruise component 300 to monitor at a relatively fixed depth. In addition, it prevents the guide rod 221 from moving relative to the fixed base 210, so that the fixed rod cannot move relative to the hull 100 during the movement of the unmanned vessel 100, thus ensuring the stability and reliability of the monitoring.

[0075] In some embodiments, the locking element 400 is a nut, and the position of the locking element 400 relative to the guide rod 221 can be adjusted by rotating the nut. In another embodiment, the locking element 400 is a flange, and the flange and guide rod 221 can be fixed and removed by flange bolts and nuts.

[0076] like Figure 2 and Figure 4 As shown, in one embodiment, the deployment and retraction frame 200 further includes at least one pair of handles 230, each pair of handles 230 including two spaced-apart handles 230, which are spaced apart at the end of the mounting base 210 facing away from the sea surface. By providing handles 230 on the mounting base 210, the position of the mounting base 210 relative to the hull 100 can be adjusted by the handles 230 when the mounting base 210 is connected to the hull 100.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
