Description

Technical Field

[0001] This utility model relates to the field of marine engineering, and in particular to a marine bio-electrode device for a ship's seabed valve box. Background Technology

[0002] The marine bio-electrode is installed on the ship's seabed valve box. Its working principle is: the electrode in the seawater is electrolyzed by a DC power supply. The metal ions generated by the electrolysis can effectively kill marine organisms in the seawater, thereby avoiding blockage problems in the seawater pipeline.

[0003] Currently, existing marine organism-proof electrodes are assembled as a single unit, consisting of an electrode and a flange. In application, they are fastened to the flange of the seat plate welded to the seabed valve box by tightening screws and nuts. This method of installation has the following drawbacks: new electrodes can only be replaced when the ship enters dry dock for maintenance. If the electrodes are used up before entering dry dock, it will cause serious problems of marine organism attachment in the ship's seabed pipelines.

[0004] The patent with publication number CN207450162U discloses a method for replacing the MGPS anti-biological device at sea. Although it achieves the purpose of replacing the anti-biological electrode at sea, it requires a person to dive underwater to assist in the replacement, which is not only troublesome but also poses a certain degree of danger. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a marine bio-electrode device for a ship's seabed valve box, which allows for safe and convenient replacement of the marine bio-electrode at any time.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A marine bio-electrode device for a ship's submersible valve box includes:

[0008] The fixed component includes a gate valve, with an upper waterproof cover and a lower waterproof cover respectively sealingly connected to the top and bottom of the gate valve. When the gate valve is opened, the upper and lower waterproof covers can communicate through the gate to form a through-sealed cavity. The bottom of the lower waterproof cover is partially blocked to form an electrode insertion port smaller than its inner diameter. The lower waterproof cover is sealed to the working port of the valve box so that the electrode insertion port can communicate with the seabed through the working port. Specifically, the lower waterproof cover can be sealed with the valve box using sealant.

[0009] An electrode component includes an electrode rod that mates with an electrode socket. A first sealing element is provided between the electrode rod and the electrode socket. A watertight cover is connected to the top of the electrode rod. A second sealing element is connected to the edge of the watertight cover so that the electrode component can seal against its inner wall when it is raised and lowered along the through-sealed cavity. The distance between the second sealing element and the bottom of the electrode rod is less than the height of the upper waterproof sleeve so that the gate valve can be closed in time after the electrode component is completely raised into the upper waterproof sleeve.

[0010] The driving component includes a driving element located above the upper waterproof cover and inside the valve box. The output end of the driving element is connected to a lifting rod. The lower end of the lifting rod is detachably connected to the watertight cover so that the driving element can position the lifting rod, along with the electrode component, in the electrode socket and allow it to exit the upper waterproof cover through the through-sealed cavity.

[0011] In one example, the drive component is a screw jack, and the lifting rod is the lifting screw of the screw jack. Alternatively, a telescopic cylinder-like structure can also be used.

[0012] In one example, the drive component is mounted above the fixed component by a support frame; to ensure that the electrode component can be completely removed from the upper waterproof cover, firstly, a sufficient distance can be left between the upper waterproof cover and the support, and secondly, the support frame can be detachably fixed to the valve box.

[0013] In one example, the first seal is a stepped sealing ring with a T-shaped socket for inserting an electrode rod inside and a snap-fit ​​portion outside. The lower waterproof cover has a snap-fit ​​platform on the outer periphery of the electrode socket that mates with the snap-fit ​​portion, so that the first seal is snapped into the electrode socket from inside the lower waterproof cover and fixed to the lower waterproof cover by screws.

[0014] In one example, a connecting portion is formed on the top outer periphery of the watertight cover, and a connecting plate is fixedly connected to the bottom of the lifting rod. The connecting plate and the connecting portion are detachably connected by a bolt and nut assembly.

[0015] The advantages of this utility model, which adopts the above-mentioned technical solution, are as follows: The marine bio-electrode device for a ship's seabed valve box, through the coordinated arrangement of fixed components, electrode components, and driving components, allows for safe and convenient replacement of the marine bio-electrode at any time. Specifically, when the electrode is depleted at sea, a person on board can safely replace it with a new electrode, and the replacement process is relatively convenient and quick.

Detailed Implementation

[0020] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0021] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] like Figure 1-3 As shown, in this embodiment, the marine bio-electrode device for the ship's seabed valve box includes a fixing component, an electrode component, and a driving component;

[0023] The fixed component includes a gate valve 1. The top and bottom of the gate of the gate valve 1 are respectively sealed and connected to an upper waterproof cover 2 and a lower waterproof cover 3. When the gate valve 1 is opened, the upper waterproof cover 2 and the lower waterproof cover 3 can be connected through the gate to form a through-sealed cavity 4. The bottom of the lower waterproof cover 3 is partially blocked to form an electrode insertion port 5 smaller than its inner diameter. The lower waterproof cover 3 is sealed and connected to the working port 7 of the valve box 6 so that the electrode insertion port 5 can be connected to the seabed through the working port 7.

[0024] The electrode component includes an electrode rod 8 that mates with the electrode socket 5. A first sealing element 9 is provided between the electrode rod 8 and the electrode socket 5. A watertight cover 10 is connected to the top of the electrode rod 8. A second sealing element 11 is connected to the edge of the watertight cover 10 so that it can seal against the inner wall of the electrode component when it is raised and lowered along the through-sealed cavity 4. The distance between the second sealing element 11 and the bottom of the electrode rod 8 is less than the height of the upper waterproof sleeve 2 so that the gate valve 1 can be closed in time after the electrode component is completely lifted into the upper waterproof sleeve 2 to prevent seawater from overflowing from the top of the upper waterproof sleeve 2.

[0025] The driving component includes a driving element 12 located above the upper waterproof cover 2 and inside the valve box 6. The output end of the driving element 12 is connected to a lifting rod 13. The lower end of the lifting rod 13 is detachably connected to the watertight cover 10 so that the driving element 12 can position the lifting rod 13 with the electrode component in the electrode socket 5 and exit the upper waterproof cover 2 through the through-sealed cavity.

[0026] Replacement process: When the electrode is in normal use, such as Figure 1-2 As shown, the gate valve 1 is in the open state, at which time the lifting rod 13 presses and locks the electrode component into the electrode socket 5. When it is necessary to check the electrode or replace it with a new electrode, the lifting rod 13 is raised by the drive component 12, which in turn raises the electrode component along the through-sealed cavity 4. During the rising process, the second seal 11 can keep the electrode component sealed to the inner wall of the through-sealed cavity 4 to prevent seawater from entering the valve box. However, some seawater will enter the through-sealed cavity below it (corresponding to the lower waterproof cover) as the electrode component rises. When the electrode component is lifted to the position through the gate valve 1 (e.g. Figure 3 (As shown), close the gate valve 1 to prevent seawater from continuing to enter and relieve seawater pressure. Then, continue lifting to pull the electrode components out of the upper waterproof cover 2, and then replace them with new electrode components.

[0027] After replacing the electrode components, the lifting rod 13 is driven by the drive component 12 into the upper waterproof cover 2 and continues to descend. When it descends above the gate valve 1, the gate valve 1 is opened, allowing the electrode components to continue descending along the through-sealed cavity 4. As it descends, it forces out the seawater that had previously entered, finally descending into the electrode insertion port 5 to complete the replacement of the electrode components. In a specific embodiment, the structure of the drive component can vary. Specifically, a screw jack can be used, where the lifting rod is the lifting screw of the screw jack, and the drive component is the remaining structure. In practical applications, the lifting screw can be manually driven by a handwheel, or it can be connected to a motor or other structures. In addition, the drive component can also use a telescopic cylinder structure to achieve the lifting and locking of the electrode components.

[0028] Furthermore, the drive component can be mounted above the fixed component via a support frame 14. To ensure the electrode component can be completely removed from the upper waterproof cover 2, the following specific measures can be taken: First, sufficient distance can be left between the upper waterproof cover 2 and the support frame 14. Second, the support frame 14 can be detachably fixed to the valve box 6. After the electrode component is lifted to a certain height, the support frame can be removed, and the electrode component can be pulled out of the upper waterproof cover 2 together for replacement. After replacement, the electrode component should be inserted into the upper waterproof cover 2 first, and then the support frame and valve box 6 should be re-fixed. The replacement process can then be repeated as described above.

[0029] In one specific embodiment, for better sealing and installation, the first sealing member 9 adopts a stepped sealing ring, forming a T-shaped socket for inserting the electrode rod inside and a snap-fit ​​portion outside. The lower waterproof cover 2 has a snap-fit ​​platform on the outer periphery of the electrode socket 5 that mates with the snap-fit ​​portion, so that the first sealing member 9 is snapped into the electrode socket 5 from inside the lower waterproof cover and fixed to the lower waterproof cover 3 by screws 15.

[0030] In one specific embodiment, the lifting rod 13 and the watertight cover 10 may, but are not limited to, adopt the following form: a connecting part is formed on the outer periphery of the top of the watertight cover 10, and a connecting plate 16 is fixedly connected to the bottom of the lifting rod 13. The connecting plate and the connecting part are detachably connected by a bolt and nut assembly 17, which makes it easier to replace the electrode components.

[0031] In one specific embodiment, in order to observe the rising sea level and other conditions, the upper waterproof sleeve 2 can be made into a transparent sleeve.

[0032] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0033] Any aspects of this utility model not described in detail are known to those skilled in the art.
