Description

Technical Field

[0001] The invention relates to the technical field of preventing and controlling fouling of swamp clams in a water delivery system, and in particular to a solenoid structure used in a magnetic thermal clam cleaner for a water delivery pipeline. Background Art

[0002] In recent years, the benthic animal of the family Mytilidae, the swamp clam (commonly known as freshwater shellfish), has widely invaded major water supply systems and hydropower engineering environments, causing serious biological fouling problems, especially in cooling water technical water supply systems, causing blockages and even causing unplanned shutdowns of projects. The swamp clam larvae attach to the inner wall of the water supply pipeline, and gradually develop and secrete foot threads to stably attach to the wall. As the swamp clam aggregation grows, the pipeline corrodes and blocks, and the water supply efficiency is reduced, which seriously threatens the safety and service life of the engineering facilities. This problem of mussel biofouling is widespread both at home and abroad, not only posing a threat to engineering safety, but also causing potential adverse effects on the ecosystem.

[0003] At present, the main solutions to the biofouling problem of limnid clams include physical removal, chemical reagent treatment, and biocidal treatment. Although these methods can reduce the pollution hazards of limnid clams to a certain extent, they all have disadvantages such as difficulty in implementation, high cost, and potential pollution to the environment. For example, physical removal requires special equipment and a large amount of manpower, and there are problems such as large equipment loss and high maintenance costs during implementation; although chemical reagent treatment has a certain effect, there is a risk of residual agent polluting the water quality; the biocidal treatment effect is unstable and the cycle is long, making it difficult to completely remove limnid clams. Therefore, there is an urgent need for a more efficient, environmentally friendly, ecological, safe and economical method for the prevention and control of limnid clams to deal with the problem of biofouling of limnid clams in engineering water pipelines.

[0004] As an innovative clam cleaning technology, the magnetothermal method generates a high-frequency strong magnetic field by laying out a solenoid structure inside the water pipeline to activate superparamagnetic nanoparticles (SMNP) suspended in the water. Under the action of the magnetic field, the nanoparticles heat up rapidly, producing a local thermal effect, which can effectively kill the larvae of the marsh clams in the water body, and can also drive off or directly kill the larvae that have attached to the pipe wall. The magnetothermal method can avoid the mechanical damage caused by physical removal and avoid secondary pollution of the water body, providing a more efficient and sustainable biofouling control solution. However, the traditional solenoid structure adopts a long solenoid structure that cannot move relatively, and can only be installed in a long straight water pipeline. Most water pipelines have complex shapes, with bends, branches, and different pipe diameters. The traditional long solenoid structure installed at the bend of the water pipeline may cause blockage problems, affecting the normal operation of the clam cleaner in the complex water pipeline, and it is inconvenient to install, disassemble and maintain. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to provide a solenoid structure for a magnetic thermal clam cleaner for a water pipeline, which is suitable for the complex shape of the water pipeline, is easy to install, disassemble and maintain, is safe and reliable, can efficiently remove the clams in the water pipeline, and reduces manual intervention.

[0006] The solenoid structure for a magnetic thermal clam cleaner for a water pipeline according to an embodiment of the present invention is used to be arranged in a water pipeline, and includes solenoid modules connected in series in sequence, wherein the solenoid modules are short solenoid modules, and adjacent solenoid modules are movably connected. The movably connected solenoid modules are suitable for being arranged at a bend or non-bend of the water pipeline, and each solenoid module is used to generate a strong alternating magnetic field.

[0007] Among them, from the perspective of installation, disassembly and maintenance, since multiple solenoid modules are connected in series, each single solenoid module is a short solenoid module, that is, the axial length of a single solenoid module is shorter than the axial length of a traditional long solenoid structure that cannot move relatively by itself. Multiple short solenoid modules connected in series replace the traditional long solenoid structure that cannot move relatively by itself and are arranged on the inner wall surface of the water pipeline. By utilizing the active connection parts between adjacent solenoid modules to be arranged correspondingly at the turning points of the water pipeline including branches, multiple short solenoid modules and the active connection between multiple short solenoid modules can freely rotate to adapt to various complex forms of water pipelines; at the same time, for water pipelines with different diameters, the radial dimensions of the solenoid modules can be designed accordingly to match the inner diameter dimensions of the water pipeline. Therefore, the solenoid structure of the magnetic thermal clam cleaner for water pipelines according to the embodiment of the present invention has good flexibility and versatility in use, can smoothly adapt to the complex pipeline forms such as the elbows and branch pipes of the water pipeline, will not affect the normal passage of water flow, avoids the blockage problem and the inconvenience of installation that may be caused by the traditional long solenoid structure that cannot move relatively at the bends of the water pipeline, and ensures the normal operation of the clam cleaner under various water pipeline environments. Of course, since a plurality of solenoid modules are connected in series, the solenoid structure of the magnetic thermal clam cleaner for water pipelines according to the embodiment of the present invention can still be conveniently installed in a long linear water pipeline without a bend. Since the solenoid module is modularly designed, it is easy to install, disassemble and maintain. The solenoid module with modular design can not only be quickly replaced or repaired according to actual needs, but also greatly reduces the equipment maintenance cost and operation difficulty, and is suitable for long-term use in large-scale projects.

[0008] In terms of the effect of removing and preventing clams, the solenoid module generates a strong alternating magnetic field in the water pipeline through an external power supply, activates the superparamagnetic nanoparticles suspended in the water, and under the action of the magnetic field, the nanoparticles quickly heat up to produce a local thermal effect. This local thermal effect effectively kills the larvae of the limpet larvae in the water pipeline and drives away or kills the adult clams attached to the pipeline wall, so that the solenoid structure of the magnetic thermal clam cleaner for water pipelines in the embodiment of the present invention can achieve efficient, environmentally friendly and economical removal and killing of limpet larvae, while avoiding the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0009] The solenoid module adjusts the frequency and intensity of the magnetic field through an external power supply, which can achieve automatic and intelligent control. The frequency and intensity of the magnetic field are adjusted in real time through the monitoring system. The frequency range of the magnetic field is from long wave to medium wave to ensure that the magnetic nanoparticles can produce sufficient thermal effect in a short time. The magnetic field strength is required to penetrate deep into the inner wall of the water pipe to effectively cover the entire water flow channel, kill the larvae or force them to leave the attachment surface. In this way, it can ensure that the best killing effect can be maintained under different working conditions, reduce manual intervention, and improve the intelligence level of the clam cleaning system.

[0010] In summary, the solenoid structure used for the magnetic thermal clam cleaner for water pipelines according to the embodiment of the present invention has the following advantages:

[0011] (1) Adapting to the complex shapes of water pipelines: Through the design of active series connection and short solenoid modules, it can smoothly pass through complex water pipelines, including small radius bends, ensuring the wide applicability of the clam cleaner in various water delivery systems.

[0012] (2) Efficient generation of magnetic field: The solenoid module 10 can customize the magnetic field parameters according to the shape and size of the water pipeline, ensuring that the clams attached to the pipeline can be efficiently killed and the cleaning cycle of the water pipeline can be extended.

[0013] (3) Modular design, easy to disassemble and maintain: The solenoid structure 1000 adopts a modular design, which is easy to disassemble and maintain, suitable for long-term online operation, and reduces the cost and difficulty of cleaning the pipeline.

[0014] (4) Automation and intelligent control: It can be combined with modern control technology to achieve automatic control. The magnetic field strength and frequency can be adjusted in real time through the monitoring system to ensure the best killing effect under different working conditions, reduce manual intervention, and improve the intelligence level of the system.

[0015] (5) Safe and reliable: It can avoid corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0016] In some embodiments, adjacent solenoid modules are connected via a movable connection member, and the movable connection member is suitable for being arranged at a bend or a non-bend of the water delivery pipeline.

[0017] In some embodiments, the movable connection member is a telescopic universal joint.

[0018] In some embodiments, the solenoid module includes a solenoid body, a cylindrical frame and an anti-collision member, the solenoid body is fixed on the outer circumference of the cylindrical frame, the anti-collision member is fixed on the outer circumference of the cylindrical frame, and the anti-collision member is used to support the inner wall surface of the water pipe so that there is a distance between the solenoid and the inner wall surface of the water pipe.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Combine the following Figure 1 to Figure 2 A solenoid structure 1000 for a magnetic thermal cleaner for a water pipeline according to an embodiment of the present invention is described.

[0033] like Figure 1 and Figure 2 As shown, the solenoid structure 1000 for the magnetic thermal clam cleaner for water pipelines of an embodiment of the present invention is used to be arranged in a water pipeline. The water pipeline here refers to a water pipeline in a water supply system and a hydropower project that needs to be prevented from being polluted by swamp swamp clams. Usually, the water pipeline has a complex shape and has bends, branch pipes, and pipes of different diameters.

[0034] The solenoid structure 1000 for a magnetic thermal clam cleaner for a water pipeline in an embodiment of the present invention comprises solenoid modules 10 connected in series in sequence, wherein the solenoid modules 10 are short solenoid modules, and the solenoid modules 10 are movably connected to each other. The movably connected solenoid modules 10 are suitable for being arranged at the bends and non-bends of the water pipeline, and each solenoid module 10 is used to generate a strong alternating magnetic field.

[0035] Among them, from the perspective of installation, disassembly and maintenance, since multiple solenoid modules 10 are connected in series, each single solenoid module 10 is a short solenoid module 10, that is, the axial length of a single solenoid module 10 is shorter than the axial length of a traditional long solenoid structure that cannot move relatively by itself. Multiple short solenoid modules connected in series replace the traditional long solenoid structure that cannot move relatively by itself and are arranged on the inner wall surface of the water pipeline. By utilizing the active connection parts between adjacent solenoid modules 10 to be correspondingly arranged at the turning points of the water pipeline including the branches, multiple short solenoid modules 10 and the active connection between multiple short solenoid modules 10 can freely rotate to adapt to various complex forms of water pipelines; at the same time, for water pipelines with different diameters, the radial dimensions of the solenoid modules 10 can be designed accordingly to match the inner diameter dimensions of the water pipeline. Therefore, the solenoid structure 1000 for the magnetic thermal clam cleaner for water pipelines of the embodiment of the present invention has good flexibility and versatility in use, can smoothly adapt to the complex pipeline forms such as the elbow and branch pipe of the water pipeline, will not affect the normal passage of water flow, avoids the blockage problem and the problem of inconvenience in installation that the traditional long solenoid structure that cannot be relatively movable itself may cause at the turning point of the water pipeline, and ensures the normal operation of the clam cleaner under various water pipeline environments. Of course, since a plurality of solenoid modules 10 are connected in series, the solenoid structure 1000 for the magnetic thermal clam cleaner for water pipelines of the embodiment of the present invention can still be conveniently installed in a long linear water pipeline without a bend. Since the solenoid module 10 is modularly designed, it is easy to install, disassemble and maintain. The modularly designed solenoid module 10 can not only be quickly replaced or repaired according to actual needs, but also greatly reduces the equipment maintenance cost and operation difficulty, and is suitable for long-term use in large-scale projects.

[0036] In terms of the effect of removing and preventing clams, the solenoid module 10 generates a strong alternating magnetic field in the water pipeline through an external power supply, activates the superparamagnetic nanoparticles suspended in the water, and under the action of the magnetic field, the nanoparticles quickly heat up to produce a local thermal effect. This local thermal effect effectively kills the larvae of the limpet larvae in the water pipeline and drives away or kills the adult clams attached to the pipeline wall, so that the solenoid structure 1000 of the magnetic thermal clam cleaner for water pipelines of the embodiment of the present invention can achieve efficient, environmentally friendly and economical removal and killing of limpet larvae, while avoiding the corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0037] The solenoid module 10 can adjust the frequency and intensity of the magnetic field through an external power supply to achieve automatic and intelligent control. The frequency and intensity of the magnetic field are adjusted in real time through the monitoring system. The frequency range of the magnetic field is from long wave to medium wave frequency band to ensure that the magnetic nanoparticles can produce sufficient thermal effect in a short time. The magnetic field intensity is required to be able to penetrate deep into the inner wall of the water pipe to effectively cover the entire water flow channel, kill the larvae or force them to leave the attachment surface. In this way, it can be ensured that the best killing effect can be maintained under different working conditions, reduce manual intervention, and improve the intelligence level of the clam cleaning system.

[0038] In summary, the solenoid structure 1000 for a magnetic thermal clam cleaner for a water pipeline according to an embodiment of the present invention has the following advantages:

[0039] (1) Adapting to the complex shapes of water pipelines: Through the design of active series connection and short solenoid modules 10, it can smoothly pass through complex water pipelines, including small radius bends, ensuring the wide applicability of the clam cleaner in various water delivery systems. Multiple short solenoid modules 10 are connected in series to ensure that they can adapt to pipelines with small bending radii.

[0040] (2) Efficient generation of magnetic field: The solenoid module 10 can customize the magnetic field parameters according to the shape and size of the water pipeline, ensuring that the clams attached to the pipeline can be efficiently killed and the cleaning cycle of the water pipeline can be extended.

[0041] (3) Modular design, easy to disassemble and maintain: The solenoid structure 1000 adopts a modular design, which is easy to disassemble and maintain, suitable for long-term online operation, and reduces the cost and difficulty of cleaning the pipeline.

[0042] (4) Automation and intelligent control: It can be combined with modern control technology to achieve automatic control. The magnetic field strength and frequency can be adjusted in real time through the monitoring system to ensure the best killing effect under different working conditions, reduce manual intervention, and improve the intelligence level of the system.

[0043] (5) Safe and reliable: It can avoid corrosion or pipeline damage problems that may be caused by traditional chemical cleaning.

[0044] In some embodiments, adjacent solenoid modules 10 are connected by movable connectors 20, and the movable connectors 20 are suitable for being arranged at the bends or non-bends of the water pipeline. The movable connectors 20 enable multiple short solenoid modules 10 to rotate freely and adapt to various complex shapes of pipelines, which not only ensures the flexibility and versatility of the solenoid structure 1000 of the magnetic thermal clam cleaner for water pipelines of this embodiment, but also can smoothly adapt to complex pipeline forms such as bends and branches, and will not affect the normal passage of water flow, and avoids the blockage problem that may be caused by the traditional long solenoid structure 1000 whose parts cannot be relatively movable at the bends of the pipeline, and ensures the normal operation of the clam cleaner in various pipeline environments.

[0045] In some embodiments, the movable connecting member 20 is a telescopic universal joint. The telescopic universal joint enables the multiple short solenoid modules 10 to rotate freely and adapt to various complex shapes of pipes, which not only ensures the flexibility and versatility of the solenoid structure 1000 of the embodiment for the magnetic thermal clam cleaner for water pipelines, but also can smoothly adapt to complex pipe forms such as bends and branches without affecting the normal passage of water flow, avoids the blockage problem that may be caused by the traditional long solenoid structure 1000 whose parts cannot be relatively movable at the pipe bend, and ensures the normal operation of the clam cleaner in various pipe environments.

[0046] Preferably, the telescopic universal joint is made of high-strength material. Selecting high-strength material such as stainless steel to make the telescopic universal joint ensures that the telescopic universal joint has good mechanical strength and corrosion resistance, and can withstand long-term water pressure and chemical erosion in the water pipeline.

[0047] In some embodiments, the solenoid module 10 includes a solenoid body 101, a cylindrical frame 102 and an anti-collision member 103. The solenoid body 101 is used to generate a strong alternating magnetic field. The solenoid body 101 is fixed on the outer periphery of the cylindrical frame 102. The cylindrical frame 102 supports and fixes the solenoid body 101. The anti-collision member 103 is fixed on the outer periphery of the cylindrical frame 102. The anti-collision member 103 is used to support the inner wall surface of the water pipeline so that there is a gap between the solenoid body 101 and the inner wall surface of the water pipeline to prevent the solenoid body 101 from hitting the water pipeline when the solenoid module 10 is installed in the water pipeline. The solenoid module 10 has a simple structure, is sturdy and durable, and can work stably for a long time in harsh environments.

[0048] In some embodiments, the sizes of the plurality of solenoid modules 10 are the same or different, so that the solenoid modules 10 can flexibly adapt to the complex shapes of the water pipeline.

[0049] In some embodiments, the number of turns, wire diameter, and length of the solenoid body 10 are determined according to the diameter and length of the corresponding water pipeline. In order to enable the solenoid module 10 to perform optimally in different water pipeline systems, key parameters such as the number of turns, wire diameter, and length are customized during the manufacturing process. These parameters are tailored according to the actual specifications of the water pipeline to ensure that the solenoid module 10 can generate an adaptable and evenly distributed magnetic field to maximize the effect of magnetic thermal cleaning.

[0050] In some embodiments, the solenoid body 101 includes a metal solenoid and an insulating layer coated on the surface of the metal solenoid. The metal solenoid has good electrical conductivity, can effectively conduct current and generate a high-frequency alternating magnetic field. The insulating layer is coated on the surface of the metal solenoid to avoid leakage, and can prevent the water in the water pipe, the cylindrical frame 102, the anti-collision member 103, etc. from conducting electricity, thereby ensuring the long-term use safety of the solenoid structure 1000 of the magnetic thermal clam cleaner for water pipes in this embodiment.

[0051] In some embodiments, the metal solenoid is a high-electricity metal solenoid, which can be made of copper or aluminum, and can effectively conduct current and generate a high-frequency alternating magnetic field. The insulating layer is made of a high-temperature resistant and corrosion-resistant insulating material, such as a polyimide material, which has good high-temperature resistance and corrosion resistance, and is conducive to improving the long-term use safety of the solenoid structure 1000 for the magnetic thermal clam cleaner for water pipelines of this embodiment.

[0052] In some embodiments, the telescopic universal joint is connected between the cylindrical frames 102 of adjacent solenoid modules 10 for easy connection.

[0053] In some embodiments, the radial cross section of the cylindrical frame 102 is circular or polygonal, which can be determined according to actual needs. The cylindrical frame 102 and the anti-collision member 103 are both made of high-strength, corrosion-resistant insulating materials.

[0054] In some embodiments, the magnetic field frequency and intensity of multiple solenoid modules 10 are independently controlled. Since the number and distribution of marsh clam larvae in different water pipelines vary greatly, the magnetic field frequency and intensity of multiple solenoid modules 10 are independently controlled, and the magnetic field intensity and frequency generated by the solenoid module 10 can be adjusted in real time according to the degree of marsh clam contamination in the corresponding water pipeline to ensure that the magnetic nanoparticles can be quickly heated to a temperature that kills the marsh clam larvae. The magnetic field generated by the solenoid module 10 is monitored and adjusted to ensure that the solenoid structure is always in the best operating state.

[0055] The solenoid structure 1000 for a magnetic thermal cleaner for a water pipeline according to an embodiment of the present invention is described below by taking a specific example.

[0056] Assume that in a hydropower project, the diameter of the technical water pipeline is 250mm, the material of the water pipeline is steel, and the total length of the water pipeline is about 10m. The water delivery system has been facing the problem of fouling by clams, which seriously affects the normal operation. A solution for efficient removal of clams is needed.

[0057] To this end, a magnetic thermal clam cleaner is designed, using a solenoid structure 1000 to ensure that the solenoid structure 1000 can adapt to pipes with a small bending radius and complex pipe systems and effectively kill the larvae of the marsh clam. During implementation, the solenoid can be flexibly installed and maintained through modular design, and customized production can be carried out according to actual application needs.

[0058] (1) Material selection of solenoid body 101:

[0059] ① Material of the solenoid: Select a highly conductive and corrosion-resistant material - copper tube to ensure long-term stable operation in a water environment while providing excellent current conductivity. The diameter of the copper tube is selected to be 5mm, which can withstand strong electromagnetic induction under high-frequency current without heating or material deformation.

[0060] ②Insulation layer material: In order to ensure that the current does not leak during the transmission process and to prevent the current from directly contacting the water inside the pipeline, a layer of high-temperature resistant and corrosion-resistant polyimide insulation material is wrapped around the copper pipe. This material can withstand the heating effect of high-frequency electromagnetic fields and maintain its insulation properties.

[0061] (2) Design parameters of the solenoid module 10

[0062] According to the specific conditions of the water pipeline, determine the following solenoid design parameters:

[0063] ① Length of the solenoid module 10: Each solenoid module 10 is 0.1 m long, and a plurality of short solenoid modules 10 are connected in series to ensure that they can adapt to pipes with a smaller bending radius.

[0064] ② Number of turns of the solenoid body 101: Each solenoid body 101 has 5 turns, which can generate a uniform and strong alternating magnetic field.

[0065] ③ Number of modules: 3 solenoid modules 10 are arranged and connected by universal joints to ensure their flexibility.

[0066] (3) Fabrication of the Solenoid Module 10

[0067] ① Preparation of copper tubes coated with an insulating layer: prepare copper tubes according to the designed wire diameter and length, each copper tube is 1 m long and is used to wind each solenoid module 10.

[0068] ② Winding process: Use a special winding machine for precise winding. Wind the copper tube evenly on a core shaft with a diameter of 50mm, keep the pitch constant, ensure that each solenoid is wound 5 times, and the coils are arranged closely and neatly to avoid gaps causing uneven electromagnetic fields.

[0069] ③ Support structure installation: After winding, the solenoid is installed on a high-strength, corrosion-resistant polyethylene cylindrical tubular frame 102. The design of the tubular frame 102 must ensure that the solenoid is not easily deformed by water flow impact when installed in the pipeline, while ensuring its flexibility to adapt to the curved part of the pipeline.

[0070] (4) Design and connection of telescopic universal joint

[0071] In order to adapt to the small radius bend area, a telescopic universal joint is designed to enable multiple short solenoid modules 10 to rotate freely and adapt to various complex shapes of pipes. The production process is as follows:

[0072] ① Material selection for telescopic joint: Use high-strength stainless steel to make telescopic joint to ensure that it has good mechanical strength and corrosion resistance, and can withstand long-term water pressure and chemical erosion in water pipelines.

[0073] ② Telescopic universal joint manufacturing process: multiple telescopic universal joints are manufactured through precision machining, and the two ends of each telescopic universal joint are connected to adjacent solenoid modules 10 to ensure stable and flexible connections to adapt to small turning radius in the pipeline and avoid bending stress or blockage of the solenoid module 10 in the pipeline.

[0074] ③Connection step: Each solenoid module 10 is connected in series with the adjacent solenoid module 10 through a telescopic universal joint, and finally forms an integral device with flexible length adjustment. This design ensures that the solenoid module 10 can smoothly pass through various bends, branches and narrow areas in the water pipeline.

[0075] (5) Magnetic field frequency and intensity control module

[0076] In order to achieve the best magnetocaloric effect, an intelligent control module is designed to adjust the frequency and intensity of the magnetic field through an external power supply. The production steps of the intelligent control module are as follows:

[0077] ① Control circuit design: Through precise circuit design, the frequency range of alternating magnetic field suitable for removing clams in water pipelines (long wave to medium wave frequency, usually 10-100kHz) is selected. The control circuit can adjust the magnetic field strength and frequency generated by the solenoid in real time according to the degree of contamination of clams in the pipeline, ensuring that the magnetic nanoparticles can quickly heat up to the temperature that kills the larvae of clams.

[0078] ②Power controller installation: The intelligent control module is connected to the external power supply and connected to the solenoid through a signal cable to ensure that the magnetic field state can be monitored in real time and adjusted. The power controller is installed in the equipment cabin outside the water pipeline for easy maintenance and operation.

[0079] (6) Installation and debugging

[0080] After the solenoid structure 1000 is manufactured, it is installed in the actual water pipeline. The installation steps are as follows:

[0081] ① Modular installation: According to the actual length of the water pipeline, the solenoid modules 10 are connected in sequence through telescopic universal joints and arranged along the inner wall of the water pipeline. Since the solenoid structure 1000 has a good flexible design, it can smoothly pass through the bend area, branch area and narrow part of the water pipeline.

[0082] ② Electromagnetic field testing and debugging: After installation, connect the intelligent control module to the external power supply, start the system and conduct preliminary debugging. Through the electromagnetic field testing instrument, ensure that the magnetic field strength and frequency generated by the solenoid in the water pipeline meet the design requirements, can activate the magnetic nanoparticles and quickly heat up, and achieve the effect of killing the clams.

[0083] ③ Swamp clam removal test: After the system is debugged, a preliminary swamp clam removal experiment is conducted to monitor the mortality rate of swamp clam larvae in the pipeline and the removal of attachments in the pipeline. Based on the test results, the magnetic field strength and frequency are further adjusted to ensure that the system can operate efficiently and effectively in the long term.
