[0040] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] like Figures 1 to 3 As shown, according to an embodiment of the present disclosure, a sea pipe structure is proposed, including: a pipe body assembly 100, which is formed with a liquid inlet end 101, a liquid discharge end 102 and a liquid passage 103, and the liquid passage 103 is located between the liquid inlet end 101 and the liquid discharge end 102; a sacrificial anode plate 200, which is arranged on the pipe body assembly 100, and the sacrificial anode plate 200 is located in the liquid passage 103; wherein the sacrificial anode plate 200 is provided with a plurality of liquid passage holes 201, and the liquid passage holes 201 are conductive along the direction from the liquid inlet end 101 to the liquid discharge end 102.

[0042] The sea pipe structure provided by the embodiment of the present disclosure includes a pipe body assembly 100 and a sacrificial anode plate 200, wherein the pipe body assembly 100 is formed with a liquid inlet end 101, a liquid discharge end 102 and a liquid flow channel 103 located between the liquid inlet end 101 and the liquid discharge end 102, so that the pipe body assembly 100 can be used for circulating liquid, and the sacrificial anode plate 200 is arranged on the pipe body assembly 100 and is located in the aforementioned liquid flow channel 103, so that the sacrificial anode plate 200 can be used as a protective electrode to protect the pipe body assembly 100, which can reduce the corrosion of the pipe body assembly 100 in practical applications, prolong the service life of the pipe body assembly 100, and reduce the risk of damage to the pipe body assembly 100. Risk is reduced, which is beneficial to improving the safety and reliability of the sea pipe structure; in addition, the sacrificial anode plate 200 is also provided with a plurality of liquid holes 201 which are connected in the direction from the aforementioned liquid inlet end 101 to the aforementioned liquid discharge end 102, so that when the liquid in the pipe body assembly 100 flows through the sacrificial anode plate 200, the sacrificial anode plate 200 can filter the liquid and intercept the dirt carried in the liquid, which can reduce the amount of dirt carried by the liquid, which is beneficial to reducing the risk of dirt clogging the valve components downstream of the sea pipe structure in actual applications, and reducing the erosion and corrosion of the pipe body assembly 100 by dirt, reducing the probability of the valve components not being closed tightly, and providing a guarantee for the smooth operation of the valve components.

[0043] It should be noted that the sea valve structure provided in the embodiment of the present disclosure can be set on a ship or used as a component of a ship in actual application. For example, it can be used as a pipe fitting of a sea pipeline of a ship. Accordingly, the sea pipe structure can be used to be connected to the sea valve. For example, the sea pipe structure can be arranged at the liquid inlet end 101 of the sea valve, thereby reducing the probability of failure of the sea valve and the valve components downstream of the sea valve.

[0044] It is understandable that the tube body assembly 100 and the sacrificial anode plate 200 can both be made of metal materials, and the material reducibility of the sacrificial anode plate 200 is higher than that of the tube body assembly 100. Exemplarily, the material of the tube body assembly 100 can be, but not limited to, alloy or cast iron, for example, copper-nickel alloy; the material of the sacrificial anode plate 200 can be, but not limited to, low-potential materials such as iron alloy, magnesium alloy, aluminum alloy, for example, iron-nickel alloy. In practical applications, the material of the tube body assembly 100 can be selected in combination with the material of the docking component, for example, it can be consistent with the material of the aforementioned docking component, and can be selected in combination with actual needs, and no excessive restrictions are made here.

[0045] It is understandable that if Figure 1 As shown, in actual application, the thickness direction of the sacrificial anode plate 200 can be consistent with the direction from the aforementioned liquid inlet end 101 to the liquid discharge end 102; the cross-sectional shape of the sacrificial anode plate 200 can match the cross-sectional shape of the liquid discharge channel, and accordingly, the peripheral side of the sacrificial anode plate 200 can be connected to the inner wall of the tube body assembly 100, and the cross-sectional area of ​​the sacrificial anode plate 200 can be greater than or equal to the cross-sectional area of ​​the liquid discharge channel, thereby facilitating the improvement of the interception range of the sacrificial anode plate 200 in the liquid discharge channel and improving the filtering effect of the sacrificial anode plate 200 on dirt.

[0046] It is understandable that the aforementioned liquid may be but is not limited to seawater; the aforementioned dirt may be but is not limited to mud, algae, plankton, etc. mixed in seawater.

[0047] like Figure 1 As shown, in some examples, there are multiple sacrificial anode plates 200 , and the multiple sacrificial anode plates 200 are arranged at intervals along the direction from the liquid inlet end 101 to the liquid discharge end 102 .

[0048] In this technical solution, the sea-going pipe structure may include a plurality of the aforementioned sacrificial anode plates 200 arranged at intervals in the direction from the liquid inlet end 101 to the liquid discharge end 102. Based on the aforementioned arrangement, on the one hand, when liquid flows in the pipe body assembly 100, the liquid may flow through the plurality of sacrificial anode plates 200 in sequence, so that the sea-going pipe structure may utilize the plurality of sacrificial anode plates 200 to perform multi-level filtration on the liquid, thereby improving the filtration effect of the sea-going pipe structure, further reducing the risk of dirt clogging valve components downstream of the sea-going pipe structure, and reducing the probability of valve components being lax; on the other hand, the overall volume of the sacrificial anode plates 200 may also be increased, thereby improving the corrosion protection effect of the sacrificial anode plates 200 on the pipe body assembly 100, further extending the service life of the pipe body assembly 100, and helping to reduce the maintenance frequency and maintenance cost of the sea-going pipe structure.

[0049] like Figure 1 As shown, in some examples, the tube body assembly 100 includes: a liquid inlet tube 110, formed with a first connection end and a liquid inlet end 101; a liquid discharge tube 120, formed with a second connection end and a liquid discharge end 102; an intermediate tube 130, detachably connected between the first connection end and the second connection end; wherein at least one sacrificial anode plate 200 is arranged between the first connection end and one end of the intermediate tube 130, and at least one sacrificial anode plate 200 is arranged between the second connection end and the other end of the intermediate tube 130.

[0050] In this technical solution, the aforementioned tube body assembly 100 may include an inlet pipe 110, a discharge pipe 120 and an intermediate pipe 130 connected between the inlet pipe 110 and the discharge pipe 120, wherein the inlet pipe 110 is formed with a first connecting end and the aforementioned inlet end 101, and the discharge pipe 120 is formed with a second connecting end and the aforementioned discharge end 102. It can be understood that the first connecting end and the aforementioned inlet end 101 are two ends of the inlet pipe 110 that are separated from each other, and the second connecting end and the aforementioned discharge end 102 are two ends of the discharge pipe 120 that are separated from each other. The inlet pipe 110 and the discharge pipe 120 can be connected to the two ends of the intermediate pipe 130 through the first connecting end and the second connecting end, respectively, and the inlet pipe 110 and the intermediate pipe 130 are connected to the two ends of the intermediate pipe 130 through the first connecting end and the second connecting end, and the inlet pipe 110 and the intermediate pipe 130 are connected to the two ends of the intermediate pipe 130 through the first connecting end and the second connecting end, respectively. The connection between the first connecting end and the drain pipe 120 is detachable; at the same time, at least one of the aforementioned sacrificial anode plates 200 can be respectively arranged between the first connecting end and one end of the intermediate pipe 130 and between the second connecting end and the other end of the intermediate pipe 130. Based on the aforementioned arrangement, on the one hand, a plurality of sacrificial anode plates 200 can be arranged at intervals in the pipe body assembly 100 along the direction from the liquid inlet end 101 to the liquid outlet end, thereby improving the filtering effect of the sea-reaching pipe assembly and extending the service life of the pipe body assembly 100; on the other hand, it is also convenient to clean and maintain the sacrificial anode plates 200 by disassembling the liquid inlet pipe 110, the intermediate pipe 130 and the drain pipe 120, thereby improving the convenience of use of the sea-reaching pipe structure.

[0051] It can be understood that the sacrificial anode plate 200 is detachably connected to the tube assembly 100 , so as to facilitate the replacement of the sacrificial anode plate 200 .

[0052] It can be understood that, in actual applications, the specifications of the liquid inlet pipe 110, the intermediate pipe 130 and the liquid discharge pipe 120 can be various to form pipe body assemblies of different specifications. Based on the aforementioned setting of the technical solution, the pipe body assembly 100 can be a three-section detachable structure, so as to facilitate the combination adjustment of the aforementioned three sections according to different specification requirements, which can improve the structural simplicity and operational convenience of the sea pipe assembly.

[0053] like Figure 1 As shown, in some examples, along the direction from the liquid inlet end 101 to the first connection end, the inner diameter of at least part of the liquid inlet pipe 110 increases; along the direction from the second connection end to the liquid discharge end 102, the inner diameter of at least part of the liquid discharge pipe 120 decreases.

[0054] In this technical solution, the inner diameter of at least part of the liquid inlet pipe 110 can be increased along the direction from the liquid inlet end 101 to the first connection end, and the inner diameter of at least part of the liquid discharge pipe 120 can be reduced along the direction from the second connection end to the liquid discharge end 102. Based on the above-mentioned arrangement, the diameter of the pipe body assembly 100 can form a trend of first increasing and then decreasing along the direction from the liquid inlet end 101 to the liquid discharge end 102, which is beneficial to reducing the flow attenuation rate of the pipe body assembly 100 in actual applications, improving the liquid circulation effect of the pipe body assembly 100, and improving the liquid circulation efficiency of the sea pipe structure.

[0055] In some examples, the ratio of the inner diameter of the first connecting end to the inner diameter of the liquid inlet end 101 is greater than or equal to 1.5 and less than or equal to 2; the ratio of the inner diameter of the second connecting end to the inner diameter of the liquid discharge end 102 is greater than or equal to 1.5 and less than or equal to 2.

[0056] In this technical solution, the proportional relationship between the inner diameter of the first connecting end of the inlet pipe 110 and the inner diameter of the inlet end 101, and the proportional relationship between the inner diameter of the second connecting end of the discharge pipe 120 and the inner diameter of the discharge end 102 are constrained. Based on the above-mentioned settings, the increase in the diameter of the inlet pipe 110 from the inlet end 101 to the first connecting end, and the decrease in the diameter of the discharge pipe 120 from the second connecting end to the discharge end 102 can be limited, thereby avoiding the inlet pipe 110 and the discharge pipe 120 from changing too much or too little along the way. While reducing the flow attenuation rate of the pipe body assembly 100, the modeling complexity of the pipe body assembly 100 can be reduced, which is beneficial to improving the molding convenience of the inlet pipe 110 and the discharge pipe 120, and saving the manufacturing cost of the inlet pipe 110 and the discharge pipe 120.

[0057] It can be understood that, in practical applications, the inner diameter of the liquid inlet end 101 and the inner diameter of the liquid discharge end 102 can be set in combination with the inner diameter of the pipe fittings connected at both ends of the sea pipe structure.

[0058] like Figure 1 As shown, in some examples, the liquid inlet pipe 110 includes a first transition pipe section 111 and a first connecting pipe section 112 connected to each other, the end of the first transition pipe section 111 away from the first connecting pipe section 112 is formed with a liquid inlet end 101, the end of the first connecting pipe section 112 away from the first transition pipe section 111 is formed with a first connecting end, and the inner diameter of the first connecting pipe section 112 is consistent with the inner diameter of the intermediate pipe 130; the liquid discharge pipe 120 includes a second transition pipe section 121 and a second connecting pipe section 122 connected to each other, the end of the second transition pipe section 121 away from the second connecting pipe section 122 is formed with a liquid discharge end 102, the end of the second connecting pipe section 122 away from the second transition pipe section 121 is formed with a second connecting end, and the inner diameter of the second connecting pipe section 122 is consistent with the inner diameter of the intermediate pipe 130.

[0059] In this technical solution, the aforementioned liquid inlet pipe 110 may include a first transition pipe section 111 and a first connecting pipe section 112, and the aforementioned liquid discharge pipe 120 may include a second transition pipe section 121 and a second connecting pipe section 122, the first connecting end is located at the first connecting pipe section 112, and the second connecting end is located at the second connecting pipe section 122, and the pipe diameters of the first connecting pipe section 112 and the second connecting pipe section 122 are consistent with the intermediate pipe 130, the inner diameter of the first transition pipe section 111 increases along the direction from the liquid inlet end 101 to the first connecting end, and the inner diameter of the second transition pipe section 121 decreases along the direction from the second connecting end to the liquid discharge end 102; based on the aforementioned arrangement, the inner diameter of the pipe body assembly 100 can be formed in a state where the middle part is larger and the two ends are smaller along the direction from the liquid inlet end 101 to the liquid discharge end 102, which is beneficial to further reduce the flow attenuation rate of the pipe body assembly 100, improve the liquid circulation effect of the pipe body assembly 100, and help improve the liquid circulation efficiency of the sea pipe structure.

[0060] like Figure 1 As shown, in some examples, the wall thickness of the first connecting pipe segment 112 and the wall thickness of the second connecting pipe segment 122 are both consistent with the wall thickness of the intermediate pipe 130; and / or

[0061] The wall thickness of the first connecting pipe section 112 is greater than the wall thickness of the first transition pipe section 111; and / or

[0062] The wall thickness of the second connecting pipe section 122 is greater than the wall thickness of the second transition pipe section 121 .

[0063] In this technical solution, the wall thickness of the first connecting pipe section 112 and the wall thickness of the second connecting pipe section 122 can be set to be consistent with the wall thickness of the intermediate pipe 130, so that the pipe body assembly 100 can have consistency and uniformity at the connection between the liquid inlet pipe 110 and the intermediate pipe 130 and at the connection between the liquid discharge pipe 120 and the intermediate pipe 130, which is beneficial to improving the structural reliability of the middle section of the pipe body assembly 100, and the aforementioned sacrificial anode plate 200 is arranged at the connection between the liquid inlet pipe 110 and the intermediate pipe 130 and at the connection between the liquid discharge pipe 120 and the intermediate pipe 130, so based on the aforementioned setting, the connection reliability between the pipe body assembly 100 and the sacrificial anode plate 200 can also be further improved.

[0064] In this technical solution, the wall thickness of the first connecting pipe section 112 can be set to be greater than the wall thickness of the first transition pipe section 111, so as to improve the structural reliability of the portion of the liquid inlet pipe 110 close to the intermediate pipe 130, which is beneficial to ensuring the connection reliability between the liquid inlet pipe 110 and the intermediate pipe 130. At the same time, the portion of the liquid inlet pipe 110 away from the intermediate pipe 130 can have a thinner wall thickness, which is beneficial to reducing the material consumption and molding difficulty of the liquid inlet pipe 110, thereby saving the use cost of the liquid inlet pipe 110.

[0065] In this technical solution, the wall thickness of the second connecting pipe section 122 can be set to be greater than the wall thickness of the second transition pipe section 121, so as to improve the structural reliability of the portion of the drain pipe 120 close to the intermediate pipe 130, which is beneficial to ensuring the connection reliability between the drain pipe 120 and the intermediate pipe 130. At the same time, the portion of the drain pipe 120 away from the intermediate pipe 130 can have a thinner wall thickness, which is beneficial to reduce the material consumption and molding difficulty of the drain pipe 120, thereby saving the use cost of the drain pipe 120.

[0066] It is understandable that, in practical applications, the three wall thickness setting methods provided in the technical solution can be used simultaneously, or any one or any two of them can be used. When the three wall thickness setting methods provided in the technical solution are used simultaneously, the structural reliability of the middle section of the tube body assembly 100 can be higher, and the aforementioned middle section can have a larger wall thickness, which is convenient for setting the corresponding pipeline docking structure and the structure for fixing the sacrificial anode plate 200 in the docking area of ​​the liquid inlet pipe 110, the liquid discharge pipe 120 and the intermediate pipe 130.

[0067] like Figure 1 and Figure 2 As shown, in some examples, the liquid inlet pipe 110 and the liquid discharge pipe 120 are both formed with a first connection portion 140 , and both ends of the intermediate pipe 130 are both formed with a second connection portion 150 , and the first connection portion 140 is detachably connected to the second connection portion 150 .

[0068] In this technical solution, both the liquid inlet pipe 110 and the liquid discharge pipe 120 are formed with a first connecting portion 140, and second connecting portions 150 suitable for detachable connection with the first connecting portion 140 are formed at both ends of the intermediate pipe 130. Based on the above-mentioned arrangement, the liquid inlet pipe 110, the intermediate pipe 130 and the liquid discharge pipe 120 can be easily disassembled and assembled, which is beneficial to further improve the ease of use of the sea pipe structure and enhance the convenience of maintenance and cleaning of the sacrificial anode plate 200.

[0069] It is understandable that the first connection part 140 and the liquid inlet pipe 110 or the liquid discharge pipe 120 can be an integrated structure, and the second connection part 150 and the intermediate pipe 130 can be an integrated structure, thereby improving the connection reliability between the liquid inlet pipe 110, the liquid discharge pipe 120 and the intermediate pipe 130.

[0070] Exemplarily, the first connection part 140 may be a first protrusion protruding from the outer wall of the liquid inlet pipe 110 or the liquid discharge pipe 120, and the second connection part 150 may be a second protrusion protruding from the outer wall of the intermediate pipe 130. Through holes are provided on the first and second protrusions. The sea pipe structure may further include a fastening assembly 500, which includes bolts, nuts and washers. Accordingly, the bolts may be inserted into the through holes, the nuts may be threadedly connected to the bolts, and the pads may be arranged between the nuts and the bolt heads, so that the first and second protrusions may be detachably connected through the fastening assembly 500. It is understandable that the fastening assembly 500 may be made of corrosion-resistant materials.

[0071] like Figure 2 As shown, in some examples, the pipe body assembly 100 further includes: a first sealing ring 160 disposed between the first connecting end and the intermediate pipe 130 ; and / or a second sealing ring disposed between the second connecting end and the intermediate pipe 130 .

[0072] In this technical solution, the pipe body assembly 100 may also include a first sealing ring 160 and / or a second sealing ring. The first sealing ring 160 is arranged between the first connecting end and the intermediate pipe 130, and the second sealing ring is arranged between the second connecting end and the intermediate pipe 130. Based on the above arrangement, the sealing performance of the connection between the liquid inlet pipe 110 and the intermediate pipe 130 and the connection between the liquid discharge pipe 120 and the intermediate pipe 130 can be improved, thereby reducing the probability of liquid leakage in the pipe body assembly 100, which is conducive to further improving the reliability and safety of the sea pipe structure.

[0073] like Figure 1 As shown, in some examples, a limiting groove 104 is formed on the inner wall of the tube assembly 100 , and the sacrificial anode plate 200 is detachably inserted into the limiting groove 104 .

[0074] In this technical solution, a limiting groove 104 can be formed on the inner wall of the tube body assembly 100, and the sacrificial anode plate 200 can be detachably inserted into the limiting groove 104. On the one hand, the connection reliability between the sacrificial anode plate 200 and the tube body assembly 100 can be improved, ensuring the corrosion protection effect of the tube body assembly 100 and the filtering effect of the liquid; on the other hand, it can also facilitate the maintenance and replacement of the sacrificial anode plate 200 in actual applications, thereby improving the convenience of use of the sea pipe structure.
