Description

Technical Field

[0001] This utility model relates to a cage-type unmanned intelligent marine organism harvesting platform, which belongs to the technical field of nuclear power environmental engineering and equipment. Background Technology

[0002] In recent years, nuclear power plants have experienced several cold source anomalies caused by marine organism invasions blocking their intakes. The threat posed by jellyfish and other marine organisms to nuclear power plants is becoming increasingly serious. Cold source failure can lead to condenser unavailability triggering shutdowns or reactor shutdowns, or even the loss of the ultimate heat sink, resulting in a nuclear safety accident. Currently, the main methods for removing marine organisms from nuclear power plant intakes are trawling by fishing boats and manual harvesting using simple tools. The primary method for intercepting marine organisms is using gillnets. Gillnets can be installed as fixed nets or by boat. Fixed nets are more difficult to install, requiring underwater piling. Boat trawling often traps fish, causing unnecessary losses. Laser extermination is another method for removing marine organisms, but laser extermination devices are expensive. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a net cage-type unmanned intelligent marine organism harvesting platform. This platform uses an unmanned vessel as a carrier and uses an open-type net collection device to clean up jellyfish and other marine organisms. It can facilitate the rapid cleanup of marine organisms in nuclear power plants during periods of marine organism outbreaks, thereby improving the safety of nuclear power plant operations.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a net cage-type unmanned intelligent marine organism harvesting platform, which is installed on an unmanned intelligent vessel; the platform is equipped with a net-type gathering device, a harvesting device, a filtering and conveying device, a discharge device, and a bubble lifting device.

[0005] The mesh gathering device adopts an open structure formed by two side meshes and a bottom mesh. The front end of the bottom mesh is wider than the rear end of the bottom mesh, and the mesh gathering device is shaped like a trumpet.

[0006] The suction pump inlet pipe of the fishing device extends into the mesh collection device, and a filter dividing grid is installed at the end of the suction pump inlet pipe; the end of the suction pump outlet pipe is located above the filter conveying device.

[0007] The filter conveyor device has a wastewater tank below the filter conveyor belt, which is inclined; the top of the filter conveyor belt is positioned above the collection tank of the discharge device; the collection tank is equipped with a sewage pump, which is connected to a discharge pipe.

[0008] In the bubble-driven lifting device, the bubble generator is connected to an air pipe, and the bottom end of the air pipe is positioned below the water surface.

[0009] Furthermore, a side mesh reinforcing rod is provided on the side mesh to increase its strength.

[0010] Furthermore, conveyor baffles are provided on both sides of the filter conveyor belt.

[0011] Furthermore, a one-way valve is installed on the vent pipe.

[0012] Furthermore, the bubble generator is an air compressor or a blower.

[0013] Furthermore, the platform also includes a navigation system, which comprises a diesel generator set, propulsion units, signal transmitting and receiving devices, and an autopilot.

[0014] Furthermore, the platform adopts a monohull structure.

[0015] Furthermore, the mesh-type collection device is made of rigid metal mesh, with an overall funnel shape, which can effectively collect marine organisms. The end of the mesh-type collection device is connected to a filter dividing grid. The filter dividing grid is equipped with the inlet of the suction pump inlet pipe, used to filter and collect large pieces of debris in the water, and to break marine organisms into pieces that the pump can suck in. The harvesting device also includes a suction pump, a suction pump inlet pipe, and a suction pump outlet pipe. Under the suction force of the pump, the harvested material is sucked into the filter conveying device through the suction inlet and pipes. The filter conveyor belt in the filter conveying device is used to filter marine organisms and marine debris from the deep-water area sucked in by the suction pump. The filtered marine organism fragments and marine debris are conveyed to the collection tank, and the filtered water is discharged outside the ship. A sludge pump in the discharge device is connected to the collection tank, and the sludge pump discharges the marine organism fragments in the collection tank through the shore discharge pipe to a transport vehicle on shore for centralized processing. The bubble-driven lifting device uses air compressors, blowers, and other bubble generators to inject high-pressure gas into the water through air pipes and aerators to generate bubbles, thereby lifting marine organisms from deeper waters to shallower waters so that they can be collected by subsequent aggregation devices.

[0016] The beneficial effects of this utility model are:

[0017] 1) Compared with existing technologies, this cleaning platform does not consider the survival of marine organisms; it takes into account both the rapid removal of marine organisms and their processing and transportation. Compared with manual fishing operations, this platform can ensure the continuity of marine organism removal operations, thereby improving the efficiency of marine organism removal.

[0018] 2) By integrating collection and emission devices, the platform can not only achieve rapid and continuous removal of marine organisms, but also transport them to designated locations for harmless treatment, completely blocking the regeneration cycle of marine organisms. This overcomes the inefficiency, high cost, and safety hazards of traditional manual fishing, and builds a solid defense for the stable operation and economic interests of nuclear power plants.

[0019] 3) The cleaning platform can automatically and continuously carry out marine organism harvesting operations, effectively preventing marine organisms from clogging the water intake, avoiding the risk of unit shutdown caused by this, and significantly improving the cold source security of nuclear facilities; solving the cold source crisis problem of coastal nuclear power plants during the marine organism outbreak period.

[0020] 4) This cleanup platform facilitates the rapid removal of marine organisms during periods of marine biodiversity outbreaks at nuclear power plants, improving operational safety and reducing potential economic losses. This platform represents not only a technological innovation but also a precise solution to existing pain points in nuclear power plant operation and management, providing a solution to address environmental challenges and safeguarding the green future of nuclear energy production.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Figure 1 and Figure 2 A cage-type unmanned intelligent marine life harvesting platform is shown, which is set on an unmanned intelligent vessel; the platform is equipped with a net collection device 1, a harvesting device 2, a filtering and conveying device 3, a discharge device 4, and a bubble lifting device 5.

[0031] The mesh-type aggregating device 1 adopts an open structure formed by two side nets 101 and a bottom net 103. The front end 105 of the bottom net 103 is wider than the rear end 104. The mesh-type aggregating device 1 is funnel-shaped and made of rigid metal mesh, which can effectively gather marine organisms. The aggregating device is installed at the front of the cleaning platform. During operation, the opening width can be adjusted to exceed the width of the boat. When moored, it must be folded and stored to not exceed the width of the boat. The end of the mesh-type aggregating device 1 is connected to the inlet of the suction pump inlet pipe 202 in the fishing device 2. The filter dividing grid 203 is set at the end of the suction pump inlet pipe 202 to filter and collect large pieces of debris in the water, and to break marine organisms into smaller pieces for suction by the suction pump 201.

[0032] In the fishing device 2, the inlet pipe 202 of the suction pump 201 extends into the mesh collection device 1, and a filter dividing grid 203 is installed at the end of the suction pump inlet pipe 202; the end of the suction pump outlet pipe 204 of the suction pump 201 is located above the filter conveying device 3. A wastewater tank 303 is installed below the filter conveyor belt 301 in the filter conveying device 3, and the filter conveyor belt 301 is inclined. The filter conveying device 3 is used to filter marine organisms and marine debris from the deep-water area sucked in by the pump, effectively increasing the content of marine debris in the catch and reducing the water content.

[0033] The top of the filter conveyor belt 301 is positioned above the collection chamber 401 of the discharge device 4. Filtered marine debris and marine garbage are transported into the collection chamber, while water is discharged directly overboard. The collection chamber 401 is equipped with a sewage pump 402, which is connected to a shore discharge pipe 403. The sewage pump 402 discharges the marine debris from the collection chamber 401 through the shore discharge pipe 403 to a transport vehicle on shore for centralized processing.

[0034] In the bubble lifting device 5, the bubble generator 501 is connected to the air pipe 502, and the bottom end of the air pipe 502 is located below the water surface. Through the air compressor, blower, and other components of the bubble generator 501, high-pressure gas is injected underwater through the air pipe 502 and aerator to generate bubbles, thereby lifting marine organisms from deeper waters to shallower waters, making it easier for the net-type collection device 1 to collect the marine organisms.

[0035] As a specific implementation, a side net reinforcing rod 102 is provided on the side net 101 to increase the strength and rigidity of the gathering net.

[0036] As a specific implementation, conveyor baffles 302 are provided on both sides of the filter conveyor belt 301 to prevent marine organisms from falling off the filter conveyor belt 301 during the conveying process.

[0037] As a specific implementation, a one-way valve 503 is provided on the vent pipe 502 to prevent water from entering the vent pipe 502 and thus damaging the bubble generator 501.

[0038] As a specific implementation, the platform also includes a navigation system, which includes a diesel generator set, a propulsion system, a signal transmitting and receiving device, and an autopilot; the navigation system ensures the navigation of the unmanned vessel, all of which are existing technologies.

[0039] As a specific implementation method, the platform adopts a monohull structure, and its main compartments include the forward pump room, collection room, engine room, bridge, and ballast water tank.

[0040] This cleaning platform uses unmanned vessels as carriers, which can improve the efficiency of marine organism cleaning operations and reduce the cost of marine organism cleaning operations.

[0041] As a specific implementation method, the operation process of the cleaning platform is as follows: before operation, the staff should clean the platform, refuel and perform other work, and conduct a pre-voyage inspection.

[0042] Upon receiving the marine organism cleanup task, the staff untied the mooring line and used a remote control device to move the vessel to the fishing area. The net-type collection device 1 was opened to its maximum opening, and the suction pump 201 was started. Under the pump's suction, marine organisms from the deep water area were shredded by the filtering grid 203. The marine organism fragments were sucked in through the suction pump inlet pipe 202 and discharged through the suction pump outlet pipe 204 onto the filter conveyor belt 301 of the filter conveyor device 3. The filter conveyor belt 301 was then activated to filter the marine organisms and marine debris sucked in by the pump from the deep water area. The filtered marine organism fragments and marine debris were then transferred to the collection tank 401, and the water was directly discharged overboard. During the operation, the filtering grid 203 and the filter screen of the filter conveyor device 3 were rinsed periodically. In the fishing area, the bubble-driven lifting device 5 is activated and kept operational. High-pressure gas is generated by an air compressor or blower and injected underwater through the vent pipe 502 to create bubbles. This drives marine life from deeper waters to shallower areas, facilitating collection by the net-type collection device 1 when the cleaning platform returns to the area. Once the collection tank 401 is full, the cleaning platform moves to the shore recovery area. The discharge device 4 discharges the marine life fragments from the collection tank 401 through the discharge pipe 403 of the sewage pump 402 to a transport vehicle on shore. During the discharge process, a flow sensor on the discharge pipe 403 can be used for weighing.

[0043] The unmanned vessel carrier of this cleaning platform can be flexibly deployed to waters where marine life gathers for fishing operations, and the unmanned vessel can ensure the continuity of operations even in inclement weather.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
