Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-seawater biological treatment of ship seawater systems, and particularly relates to an anti-seawater biological device, a seawater filter and a ship. BACKGROUND

[0002] When a ship is sailing, seawater is usually used as a cooling medium for various systems of the ship, and the seawater is discharged after heat exchange. During this period, seawater organisms and the like will adhere to the pipe wall, especially the pipe wall near the seawater filter. This not only corrodes the pipeline, but also eventually leads to a smaller pipe diameter as the seawater organisms grow and reproduce, causing the seawater filter to be blocked, thereby causing various systems of the ship to fail and seriously affecting the safety of the ship sailing. In order to eliminate the harm of seawater organisms, early ships used methods such as dosing and coating, but these methods have been eliminated. Nowadays, electrolytic anti-seawater biological devices are commonly used to prevent or eliminate seawater organisms.

[0003] The structure of the existing electrolytic anti-seawater biological device is that a copper electrode and a stainless steel rod are both installed on a seawater filter cover plate. In a working state, the copper electrode receives current as a positive electrode, and the stainless steel rod outputs current as a negative electrode. The growth of seawater organisms is inhibited by releasing copper ions through electrolysis of the copper electrode, and the stainless steel rod is overlapped on the ship body to play a role in preventing corrosion of the ship body. However, this arrangement has the following defects: 1. The installation of the stainless steel rod and the copper electrode requires a high level. If the installation distance between the stainless steel rod and the copper electrode is too far, the loop resistance will be significantly increased, which will further lead to unstable loop current, uneven consumption of copper rods, and other defects; 2. When this structure is applied to an aluminum ship, the negative electrode needs to be insulated. Because the potential difference between the stainless steel rod used as the negative electrode and the aluminum seawater filter cover plate is large, direct contact will corrode the ship body. The insulation treatment of the negative electrode is usually to coat a thick insulating layer, which has a high degree of fineness and is difficult to achieve, and the construction process is relatively complex and has a high cost.

[0019] The beneficial effects of the present application are:

[0020] The present application provides a marine bioresistant device, which is installed on a to-be-protected member. The marine bioresistant device specifically comprises a positive electrode member, a negative electrode member, and a mounting assembly. A first connecting hole is provided through the inside of the positive electrode member. The negative electrode member is at least partially fixed in the first connecting hole, and a first insulating member is arranged between the outer peripheral wall of the negative electrode member and the hole wall of the first connecting hole, thereby achieving integrated and fixed arrangement and insulation of the positive electrode member and the negative electrode member, and avoiding short circuit of the positive electrode member and the negative electrode member. First, the negative electrode member is embedded in the positive electrode member, thereby achieving integrated and modular arrangement. This not only reduces the installation difficulty of the positive electrode member and the negative electrode member, but also reduces the external connection points, thereby reducing the risk of loosening caused by the marine environment. Second, the positive electrode member is arranged around the outside of the negative electrode member, so that the electric field lines are uniformly distributed, the current distribution is more uniform, the loop current is more stable, and the local high current density area is eliminated. The global dissolution rate of the positive electrode member is consistent, the consumption is uniform, and the problem of local overconsumption or insufficient consumption of the positive electrode member caused by the interval arrangement of the positive electrode member and the negative electrode member in the traditional way is avoided, thereby prolonging the effective service life of the entire device. In addition, the marine bioresistant device further comprises a mounting assembly. The mounting assembly comprises a mounting body, and the mounting body is connected with the positive electrode member and can be fixed on the to-be-protected member. Since the positive electrode member and the negative electrode member are integrally arranged, the mounting assembly can install the positive electrode member and the negative electrode member on the to-be-protected member, thereby avoiding the defect that the direct installation of the negative electrode member on the to-be-protected member causes corrosion of the to-be-protected member in the traditional scheme. At the same time, since the mounting body is fixedly connected with the to-be-protected member, the insulating object is replaced from the negative electrode member to the mounting assembly, thereby simplifying the insulation measures and reducing the difficulty of construction process.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0034] The most common device in marine organism control is the electrolytic marine organism control device, hereinafter referred to as "marine organism control device," which is used to prevent marine organisms (such as algae, shellfish, etc.) from attaching and growing in seawater filters. In operation, the positive electrode receives current, and the negative electrode outputs current. In the electrochemical reaction, the anode (positive electrode) undergoes an oxidation reaction to release copper ions. These copper ions act as a "biocidal agent," diffusing in the seawater to form a trace toxic environment that interferes with the enzyme system and cell membranes of marine microorganisms, inhibiting their growth and attachment. Meanwhile, the cathode (negative electrode) undergoes a reduction reaction to produce hydroxide ions or hydrogen gas. The reduction reaction at the cathode maintains electrolytic balance, preventing system corrosion or electrode polarization.

[0035] Reference Figure 1 and Figure 2This embodiment proposes a marine organism protection device, specifically including an anode component 1, a cathode component 2, and an installation assembly 3. The anode component 1 has a through-hole 11, and the cathode component 2 is at least partially fixed in the first connection hole 11. A first insulating component 8 is provided between the outer peripheral wall of the cathode component 2 and the hole wall of the first connection hole 11, so as to realize the integral fixed installation and insulation of the anode component 1 and the cathode component 2, and avoid short circuit between the anode component 1 and the cathode component 2. First, the cathode 2 is embedded in the anode 1, achieving an integrated modular design. This not only reduces the installation difficulty of the anode 1 and cathode 2 but also reduces external connection points, thereby lowering the risk of loosening due to the marine environment. Second, the anode 1 surrounds the cathode 2, resulting in a more uniform distribution of electric field lines, a more uniform current distribution, and a more stable loop current. It also eliminates local high current density areas, ensuring a consistent dissolution rate and uniform consumption of the anode 1 throughout its entire range. This avoids the problem of local over-consumption or under-consumption of the anode 1 caused by the traditional method of separating the anode 1 and cathode 2, thus extending the effective life of the entire device. In addition, the marine organism protection device also includes an installation component 3, which includes an installation body 31. The installation body 31 is connected to the anode component 1 and can be fixed on the component to be protected 100. Since the anode component 1 and the cathode component 2 are integrated, the installation component 3 can install the anode component 1 and the cathode component 2 on the component to be protected 100, avoiding the defect of corrosion of the component to be protected 100 caused by the direct installation of the cathode component 2 on the component to be protected 100 in the traditional solution. At the same time, since the installation body 31 is fixedly connected to the component to be protected 100, the insulation object is changed from the cathode component 2 to the installation component 3, which simplifies the insulation measures and reduces the difficulty of construction process.

[0036] In this embodiment, the anode 1 is made of copper, and the cathode 2 is made of stainless steel. In the prior art, when the stainless steel cathode directly contacts the aluminum component 100 to be protected, the aluminum, due to the significant potential difference, will act as a sacrificial anode and be accelerated to corrode, thus accelerating the corrosion of the component 100. Therefore, insulation between the cathode 2 and the component 100 is necessary. However, using the cathode 2 as an insulator presents significant operational difficulties. Therefore, this embodiment of the marine organism protection device also includes an installation assembly 3, which includes an installation body 31. The installation body 31 serves as a fixing medium, connecting to both the anode 1 and the component 100 to be protected, thus achieving connection between the anode 1 and cathode 2 and the component 100. Furthermore, the cathode 2 will not contact the component 100 to prevent corrosion. In this embodiment, the mounting component 3 is also made of stainless steel. Therefore, a second insulating component 4 is provided between the mounting component 3 and the component to be protected 100. By changing the insulating object from the cathode component 2 to the mounting component 3, the insulation measures and installation process are simplified, and the construction process difficulty is reduced. Preferably, the second insulating component 4 can be a nylon pad, which has excellent insulation properties, can effectively prevent current from passing through, and ensures that the component to be protected 100 will not be corroded. Moreover, nylon material is lightweight and inexpensive, effectively reducing manufacturing costs.

[0037] Furthermore, the mounting component 3 also includes a fastener 32, which is fitted onto and fixed to the mounting body 31, thereby securing the mounting body 31 to the component to be protected 100. Both the mounting body 31 and the fastener 32 are made of stainless steel. Alternatively, the mounting body 31 can be adhered to the component to be protected 100 using insulating adhesive, achieving insulation while simultaneously securing the mounting body 31 to the component to be protected 100.

[0038] In this embodiment, the anode 1 is a cylindrical body, and the first connecting hole 11 extends axially within the anode 1, with the central axis of the first connecting hole 11 coinciding with the central axis of the anode 1. The cathode 2 is a thinner cylindrical body that passes through the first connecting hole 11. Therefore, the central axis of the cathode 2 coincides with the central axis of the anode 1. The cathode 2 is disposed inside the anode 1, and the two are coaxially arranged, resulting in a radially uniform distribution of electric field lines, i.e., radiating uniformly 360 degrees radially along the anode 1. This further improves the uniform distribution of current. The uniform distribution of current makes the electrochemical reaction rate on the surface of the anode 1 consistent, resulting in more uniform consumption. Furthermore, the coaxial arrangement of the anode 1 and cathode 2 also facilitates manufacturing.

[0039] Furthermore, the mounting body 31 includes a first connecting portion 311, and the anode electrode 1 has a recessed connecting groove 12 that communicates with the first connecting hole 11. The first connecting portion 311 is placed within the connecting groove 12 and threadedly engaged with it. Mechanically, the mounting body 31 and the anode electrode 1 are connected via a threaded connection, which effectively resists the dynamic load of underwater impacts and prevents loosening or detachment. Electrically, the mounting body 31 is made of stainless steel, and the anode electrode 1 is made of copper; both are conductors. The mounting body 31 and the anode electrode 1 are connected by direct contact, enabling current conduction.

[0040] Reference Figure 1 and Figure 5 The anti-marine biological control device is externally connected to a positive electrode 200 and a negative electrode 300, both of which are connected to a power source. The positive electrode 200 is connected to the mounting body 31, and the negative electrode 300 is connected to the cathode 2. Since the mounting body 31 and the anode 1 are connected in direct contact, current can be conducted. Therefore, the positive electrode 200 is connected to the mounting body 31, which acts as a conductive medium. The current is directly conducted from the mounting body 31 to the surface of the anode 1. The negative electrode 300 is connected to the cathode 2, forming a closed current loop for electrolysis. The positive electrode 200 is connected to the stainless steel mounting body 31, and the negative electrode 300 is connected to the stainless steel cathode 2. Both the positive and negative electrodes are connected to stainless steel components, utilizing the high strength of the stainless steel to withstand mechanical stress and improve connection stability.

[0041] Furthermore, the marine organism protection device also includes a positive electrode connector 5 and a negative electrode connector 6. The mounting body 31 is recessed with a wiring groove 312. The positive electrode connector 5 is connected to the wiring groove 312 to press the terminal of the positive electrode wire 200 onto the mounting body 31. The end of the negative electrode 2 is provided with a wiring portion 21. The negative electrode connector 6 can be sleeved on the wiring portion 21 of the negative electrode 2 to press the terminal of the negative electrode wire 300 onto the negative electrode 2. Specifically, the positive electrode connector 5 is a bolt, and the groove wall of the wiring groove 312 is provided with threads. The positive electrode connector 5 is threadedly connected to the wiring groove 312. When it is necessary to connect the positive electrode wire 200 to the mounting body 31, the bolt is screwed into the wiring groove 312, and then the terminal of the positive electrode wire 200 is placed between the head of the bolt and the surface of the mounting body 31. The bolt is then screwed on so that the head of the bolt presses the terminal of the positive electrode wire 200 against the surface of the mounting body 31, thus completing the fixing of the positive electrode wire 200. The negative electrode connector 6 is a nut. The outer peripheral wall of the wiring portion 21 is threaded. The diameter of the wiring portion 21 is smaller than the diameter of the body of the negative electrode 2. The body of the negative electrode 2 has an abutment portion near the connection point of the wiring portion 21. The negative electrode connector 6 is threadedly connected to the wiring portion 21. When it is necessary to connect the negative electrode wire 300 to the negative electrode 2, the terminal of the negative electrode wire 300 is placed on the abutment portion, and then the nut is placed on the wiring portion 21 and tightened, so that the nut presses the terminal of the negative electrode wire 300 tightly against the abutment portion, thus fixing the negative electrode wire 300. It should be explained that both the positive electrode wire 200 and the negative electrode wire 300 include an outer insulation layer and an inner conductor. The insulation layer prevents current leakage and protects the inner conductor. During electrical connection, part of the insulation layer needs to be stripped to expose the inner conductor, and then the conductor is connected to the positive electrode 1 and the negative electrode 2 to allow current to flow. Therefore, the terminal of the positive wire 200 refers to the part of the conductor without insulation at the end of the positive wire 200, and the terminal of the negative wire 300 refers to the part of the conductor without insulation at the end of the negative wire 300.

[0042] Because the anti-marine organism device is exposed to seawater for extended periods, and seawater has high conductivity, it is prone to current leakage. Therefore, particularly stringent insulation measures are required at the connection points of the positive electrode wire 200 and the mounting body 31, and the connection points of the negative electrode wire 300 and the cathode component 2. Thus, the anti-marine organism device also includes a first protective component and a second protective component. The first protective component fits snugly against the mounting body 31 to form a sealed cavity. The terminals of the positive electrode connector 5 and the positive electrode wire 200 are located within this sealed cavity, completely covering the interface between the terminals of the positive electrode wire 200 and the mounting body 31 and the positive electrode connector 5, preventing seawater infiltration and short circuits. The second protective component wraps around the negative electrode connector 6, the terminals of the negative electrode wire 300, and the end of the cathode component 2 near the connection point 21, completely covering the interface between the terminals of the negative electrode wire 300 and the negative electrode connector 6 and the cathode component 2, preventing seawater infiltration and short circuits.

[0043] The first protective component is insulating adhesive. After the terminal of the positive electrode wire 200 is crimped onto the mounting body 31, insulating adhesive is applied to insulate and seal the interface between the terminal of the positive electrode wire 200 and the mounting body 31 and the positive electrode connector 5. The second protective component is heat shrink tubing. After the terminal of the negative electrode wire 300 is crimped onto the negative electrode connector 2, heat shrink tubing is fitted onto the end of the negative electrode connector 6, and then heated to completely and tightly wrap the end of the negative electrode connector 6. At this point, the negative electrode connector 6, the terminal of the negative electrode wire 300, and the end of the negative electrode connector 2 near the terminal 21 are all wrapped. The heat shrink tubing completely wraps the protruding part of the negative electrode connector 2 to prevent short circuits.

[0044] The mounting body 31 has a through-hole 313 corresponding to the position of the first connecting hole 11. The cathode electrode 2 passes through the first connecting hole 11 and the second connecting hole 313. The mounting body 31 has a rotating structure. The second connecting hole 313 passes through the first connecting portion 311 of the mounting body 31, and the axis of the second connecting hole 313 coincides with the central axis of the mounting body 31. When the mounting body 31 is connected to the anode electrode 1, that is, after the first connecting portion 311 is placed in the connecting groove 12 and threaded, the axes of the first connecting hole 11 and the second connecting hole 313 are aligned and coincident, so that the cathode electrode 2 can smoothly pass through the first connecting hole 11 and the second connecting hole 313. Preferably, the diameters of the first connecting hole 11 and the second connecting hole 313 are the same and slightly larger than the outer diameter of the cathode electrode 2.

[0045] Furthermore, the mounting body 31 is also recessed with a fixing groove 314, which communicates with the second connecting hole 313. The cathode electrode 2 passes through the second connecting hole 313 and is partially located within the fixing groove 314. The anti-marine organism device also includes a filler 7, which is placed within the fixing groove 314 and wraps around the cathode electrode 2. The diameter of the fixing groove 314 is larger than the diameter of the second connecting hole 313, and the distance between the groove wall of the fixing groove 314 and the cathode electrode 2 is relatively large, thus accommodating sufficient filler 7. By setting the fixing groove 314 to accommodate the filler 7, the portion of the cathode electrode 2 located within the fixing groove 314 is wrapped, preventing seawater infiltration and ensuring the stability of the cathode electrode 2. The filler 7 can be kasi glue, which has good chemical resistance and good resistance to seawater.

[0046] It is understood that the cathode component 2 passes through the second connecting hole 313 and is partially located within the fixing groove 314. Furthermore, the cathode component 2 also passes through the first connecting hole 11. That is, the cathode component 2 is entirely connected through the fixing groove 314, the second connecting hole 313, and the first connecting hole 11, thereby radially limiting and fixing the cathode component 2. The end of the cathode component 2 extends out of the fixing groove 314 and is located outside the fixing groove 314 and the filler 7. The wiring portion 21 is located on the end extending out of the fixing groove 314 and is used for connection with the negative electrode. The wiring groove 312 is located on the side of the mounting body 31 near the fixing groove 314. Therefore, the wiring portion 21 and the wiring groove 312 are both located on the same side of the mounting body 31. Consequently, the wiring terminals of the negative electrode wire 300 and the positive electrode wire 200 are both located on the same side of the mounting body 31, standardizing the arrangement of the wiring terminals of the negative electrode wire 300 and the positive electrode wire 200 and optimizing the wiring layout.

[0047] In addition, in the anti-marine biological device, the first insulating component 8 is an insulating sleeve, fitted onto the outer peripheral wall of the cathode component 2, achieving mutual isolation between the outer peripheral wall of the cathode component 2 and the wall of the first connecting hole 11, preventing the anode component 1 and the cathode component 2 from contacting each other and thus causing a short circuit. Specifically, the portion of the first insulating component 8 located within the first connecting hole 11 isolates the cathode component 2 and the anode component 1, preventing direct contact and short circuits, thus avoiding energy loss and equipment damage due to short circuits. The portion of the first insulating component 8 located within the second connecting hole 313 isolates the cathode component 2 and the mounting body 31, also to prevent short circuits. As mentioned above, the direct contact between the mounting body 31 and the anode component 1 allows for current conduction, with current flowing directly from the mounting body 31 to the surface of the anode component 1. Therefore, the first insulating component 8 also isolates the cathode component 2 and the mounting body 31, preventing current from flowing directly from the mounting body 31 to the cathode component 2, thus preventing a short circuit. Preferably, the first insulating component 8 is made of nylon.

[0048] The marine organism protection device is installed on the protected component 100, which has mounting holes, as shown in the reference. Figure 3 The mounting assembly 3 includes a mounting body 31 and a fastener 32. The mounting body 31 also includes a second connecting part 315 and a shoulder 316. The shoulder 316 is connected to the first connecting part 311. The second connecting part 315 is located on the side of the shoulder 316 away from the first connecting part 311. The fastener 32 is specifically connected to the second connecting part 315, thereby mounting the mounting body 31 onto the mounting hole on the part to be protected 100. Specifically, when the mounting component 3 needs to be installed on the component to be protected 100, the second connecting portion 315 passes through the mounting hole, so that the shoulder 316 abuts against one side of the component to be protected 100. Then, the fastener 32 is fixed to the second connecting portion 315 protruding on the other side of the component to be protected 100, so that the fastener 32 abuts against the other side of the component to be protected 100. At this time, the fastener 32 and the shoulder 316 are located on both sides of the component to be protected 100, respectively, limiting the second connecting portion 315 so that the second connecting portion 315 will not fall off from the mounting hole, thereby fixing the mounting body 31 onto the component to be protected 100. In this embodiment, the outer peripheral sidewall of the second connecting portion 315 is provided with threads, and the fastener 32 is a nut. The fastener 32 and the second connecting portion 315 are connected by a threaded engagement.

[0049] Among them, reference Figure 4 The second insulating element 4 is an insulating pad, disposed between the mounting assembly 3 and the component to be protected 100. Specifically, it is located between the second connecting part 315 and the wall of the mounting hole, between the shoulder 316 and the component to be protected 100, and between the fastener 32 and the component to be protected 100, to prevent electrochemical reactions between the mounting assembly 3 and the component to be protected 100, thereby preventing chemical corrosion. Furthermore, since the mounting body 31 passes through the mounting hole and protrudes from the component to be protected 100, the wiring part 21 and the wiring groove 312 are both located on the same side of the mounting assembly 3 and away from the component to be protected 100, which can prevent short circuits to the component to be protected 100 and reduce the risk of corrosion of the component to be protected 100. The mounting body 31 is a one-piece molded structure, that is, the first connecting part 311, the second connecting part 315, and the shoulder 316 are integrally molded.

[0050] On the other hand, this embodiment also proposes a seawater filter, including a shell and the above-mentioned anti-marine organism device. A power source is provided inside the shell, and a positive wire 200 and a negative wire 300 are respectively connected to the positive and negative terminals of the power source. The protected component 100 includes a shell, and the anti-marine organism device is installed on the shell. At least a portion of the anode component 1 and at least a portion of the cathode component 2 are located outside the shell. The positive wire 200 is electrically connected to the anode component 1, and the negative wire 300 is electrically connected to the cathode component 2. The positive wire 200 is electrically connected to the anode component 1 by being electrically connected to the mounting body 31. The anti-marine organism device is specifically installed on the shell cover plate, using the shell cover plate of the seawater filter as the installation point. Since the seawater filter is an essential device at the inlet of the seawater cooling system, and its shell cover plate is relatively fixed and close to the seawater intake point, directly installing the anti-marine organism device on the seawater filter cover plate not only saves installation space but also allows for immediate anti-marine organism treatment. Secondly, the power supply, positive electrode wire 200, and negative electrode wire 300 are all located inside the shell, protecting them from damage caused by marine debris. The anode element 1 and at least part of the cathode element 2 are located outside the shell, forming an electrolytic circuit. The anode element 1 releases copper ions, thereby achieving anti-marine organism treatment. In addition, the seawater filter also includes a filtration unit located on the shell. When seawater passes through the filtration unit, it filters out foreign objects in the seawater, preventing them from entering the shell and damaging the power supply and wires.

[0051] On the other hand, this embodiment also proposes a ship that includes the above-mentioned seawater filter, which can effectively prevent hull corrosion problems.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
