[0002] Coastal nuclear power plants all use seawater as a cooling source to provide cooling water for steam turbines and nuclear island equipment. With changes in the marine environment, incidents of unit trips, reactor trips, or reduced power operation caused by marine organisms or marine debris intrusion occur frequently. To ensure the safety of the cooling source system, nuclear power plants have successively installed interception nets in their intake channels.

[0003] Chinese utility model patent CN219508519U discloses a waste removal system for a nuclear power plant intake interception net, including a floating raft device, a mobile interception device, a waste hoisting device, and a trestle device. The floating raft device comprises a main body of multiple floating raft modules assembled sequentially. Each floating raft module has anchor chains on its upstream and downstream sides. One end of each anchor chain is fixed to the main body of the floating raft, and the other end is secured with an anchor. This nuclear power plant intake interception net waste removal system uses a mobile interception device to suck up waste from the net bags. The mobile interception device moves based on the floating raft device, allowing for the suction of waste from multiple net bags. The waste is then transported to the waste disposal site by the waste hoisting device. This eliminates the need to hoist the net bags for waste removal, reducing on-site maintenance workload and improving waste collection efficiency. However, in existing technologies, the connection between the net bags and the suction pump is complex, using flange connections. Disassembling and assembling the net bags is time-consuming, affecting the efficiency of net bag assembly and disassembly.

[0032] like Figure 1-4 As shown, a novel floating raft fixed one-to-one suction cleaning system in this embodiment includes a floating raft 1, on which anchor blocks 3 are connected by anchor chains 2. During operation, the anchor blocks 3 are thrown to the seabed to provide anchoring force for the floating raft 1. An interception device 4 is provided on the floating raft 1.

[0033] The interception device 4 includes a net 401 and a suction pump 402. The input end of the suction pump 402 is connected to an input pipe 403, and the output end is connected to an output pipe 404. A strong magnetic ring 405 is provided at the discharge end of the net 401, and an electromagnetic ring 406 is provided at the input end of the input pipe 403. The strong magnetic ring 405 and the electromagnetic ring 406 are sealed together. During operation, the net 401 collects debris from the water. In practice, the electromagnetic ring 406 is energized, causing an attractive force between the electromagnetic ring 406 and the strong magnetic ring 405. This allows the discharge end of the mesh bag 401 to be fixedly connected to the input pipe 403. When it is necessary to remove the garbage from the mesh bag 401, the suction pump 402 is started, so that the garbage in the mesh bag 401 is transported from the input pipe 403 to the suction pump 402 and then discharged from the output pipe 404. Specifically, the garbage passes through the ring holes of the electromagnetic ring 406 and the strong magnetic ring 405. When it is necessary to disassemble the mesh bag 401, the electromagnetic ring 406 is de-energized, and the mesh bag 401 can be removed. When installing the mesh bag 401, the electromagnetic ring 406 is energized again and the electromagnetic ring 406 and the strong magnetic ring 405 are attracted and adhered.

[0034] The interception device 4 is provided in multiple sets, and the multiple sets of interception devices 4 are arranged in sequence, with three interception devices 4 in the same set.

[0035] The floating raft 1 is equipped with a main confluence pipe 5, one end of which is connected to a collection frame 6. Each output pipe 404 is connected to the main confluence pipe 5. During operation, the collection frame 6 is set on the shore 7. A pedestrian bridge 8 is set between the floating raft 1 and the shore 7. The pedestrian bridge 8 is used for staff to walk from the shore 7 to the floating raft 1. The garbage discharged from the output pipe 404 is transported from the main confluence pipe 5 to the collection frame 6 and drained, thus realizing the collection of garbage.

[0036] The floating raft 1 is equipped with an Automated Guided Vehicle (AGV) 9. A cantilever crane 10 is installed on one side of the floating raft 1. During operation, the cantilever crane 10 is positioned on the shore 7. When the suction pump 402 needs maintenance, the suction pump 402 is unloaded and placed on the AGV 9. The AGV 9 uses electromagnetic guidance to transport the suction pump 402 along a preset route to the lifting position, and then the cantilever crane 10 lifts it to the maintenance point. The cantilever crane 10 has a load capacity of 2.8 tons. Of course, other materials can also be transported by the AGV 9.

[0037] The floating raft 1 is equipped with a crane 11 and an anchor 12. When a ship docks at a temporary docking point, the ship is secured by the anchor 12 and the materials on the ship are lifted onto the floating raft 1 by the crane 11.

[0038] The float 1 includes a plurality of buoyancy modules 101 connected in sequence, and two adjacent buoyancy modules 101 are detachably and fixedly connected by a connector 102.

[0039] The buoyancy module 101 includes a support 1011 and a buoyancy tube 1012 disposed at the bottom of the support 1011. The buoyancy tube 1012 provides buoyancy to the support 1011. The buoyancy tube 1012 is made of high-density polyethylene pipe. A railing 1013 is provided on the top of the support 1011.

[0040] The connector 102 is a male and female head, and the male and female heads are respectively fixedly installed on two adjacent buoyancy modules 101. The male and female heads are fixed by a pin structure.

[0041] Specifically, the crane 11 and the anchor 12 are installed on one of the buoyancy modules 101, and a set of interception devices 4 are installed on the other buoyancy modules 101.

[0042] In summary, this novel fixed one-to-one suction cleaning system for floating rafts can achieve all-weather cleaning of garbage within the interception net without the need for surface vessels, resulting in high cleaning efficiency. A strong magnetic ring 405 and an electromagnetic ring 406 connect the net bag 401 and the input pipe 403 of the suction pump 402, enabling rapid assembly and disassembly of the net bag 401, thus improving its efficiency. In extreme weather conditions, the connection between the suction pump 402 and the net bag 401 can be promptly disconnected to prevent damage to the net bag 401. Adjacent buoyancy modules 101 are connected by connectors 102, reducing the installation difficulty of the floating raft 1 and shortening the installation period. An automated guided vehicle 9 is used to transfer the suction pump 402 and materials, improving the system's automation level. Temporary mooring points are provided, with vessels anchored to anchors 12, and materials on board are lifted onto the floating raft 1 via a crane 11. The floating raft 1 adopts a modular design, allowing for rapid installation and replacement of individual modules.

[0043] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
