Description

Technical Field

[0001] The utility model relates to the technical field of ship marine growth prevention, in particular to a marine growth prevention device for ships. Background Art

[0002] With the continuous development of marine transportation and marine resource development, ships are operating in the ocean for longer and longer periods of time. However, there are a large number of organisms in the ocean that easily attach to the seawater systems of ships, causing many problems for the normal operation of ships.

[0003] However, in the existing anti-marine growth device, when it is necessary to replace the anti-marine growth device, it is extremely inconvenient to disassemble and install it. At the same time, the anti-marine growth device has the problem of insufficient anti-marine growth effect when in use. Utility Model Content

[0004] The problem solved by the utility model is that the installation and disassembly of the anti-marine growth device is inconvenient, and the anti-marine growth effect of the anti-marine growth device is insufficient.

[0005] To solve the above problems, the present invention adopts the following technical solution: a marine growth prevention device for ships, comprising: a seawater filter, used to generate marine growth prevention substances and filter seawater; a return pipe, one end of which is detachably arranged on the seawater filter; a seawater tank, the other end of which is detachably arranged on the seawater tank; and a liquid inlet pipe, one end of which is connected to the seawater filter and the other end is connected to the seawater tank.

[0006] Compared with existing technologies, this technical solution achieves the following technical effects: the return pipe is detachably mounted on the seawater filter, facilitating disassembly, maintenance, and installation. Furthermore, by providing the return pipe, during device operation, seawater from the seawater tank enters the seawater filter through the liquid inlet pipe. After the seawater filter generates the anti-marine biomass, some of the seawater containing the anti-marine biomass ...

[0007] Furthermore, the return pipe includes: a first flange and a second flange. The return pipe is connected to the seawater filter through the first flange, and the return pipe is connected to the seawater tank through the second flange.

[0008] Compared with existing technologies, this technical solution achieves the following advantages: when a component in the return pipe, seawater filter, or seawater tank fails, the flange connection allows for convenient local repair. Simply remove the corresponding flange to repair or replace the faulty component without requiring extensive disassembly of the entire system. Furthermore, the flange connection ensures a tight seal.

[0009] Furthermore, the return pipe includes: a first valve, which is arranged between the first flange and the seawater filter; and a second valve, which is arranged between the second flange and the seawater tank.

[0010] Compared with existing technologies, this technical solution achieves the following technical benefits: the first valve and the second valve can respectively control the connection between the return pipe and the seawater filter, and the return pipe and the seawater tank. When a return flow operation is required, the valves can be opened to allow the anti-marine biofilm material to flow from the seawater filter through the return pipe and back into the seawater tank, achieving material recycling and improving the efficiency of the anti-marine biofilm material. Furthermore, when the device is undergoing maintenance or a malfunction occurs, the valves can be closed to isolate the return pipe from the seawater filter and the seawater tank, facilitating independent maintenance of each component without affecting the normal operation of other components.

[0011] Furthermore, the seawater tank includes a water inlet coarse filter, which is arranged at the bottom of the seawater tank.

[0012] Compared with existing technologies, this solution achieves the following technical benefits: the coarse inlet filter effectively filters seawater entering the seawater tank, blocking solid impurities, marine debris, and other substances in the seawater. This prevents impurities from entering the pipes of the anti-marine growth device, reduces the risk of pipe blockage, extends the pipe life, and reduces maintenance costs.

[0013] Furthermore, the return pipe also includes a nozzle, which is connected to the seawater tank and is arranged close to the water inlet coarse filter.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the nozzle can evenly spray the anti-marine biological substance flowing back from the seawater filter into the seawater tank, especially near the position of the water inlet coarse filter, so that the anti-marine biological substance can be mixed with the seawater entering the seawater tank more quickly, thereby improving the backflow effect of the anti-marine biological substance.

[0015] Furthermore, the anti-marine growth device includes: a liquid outlet pipe, one end of the liquid outlet pipe is connected to the seawater filter, and the other end of the liquid outlet pipe is connected to the seawater system of the entire ship.

[0016] Compared with existing technologies, this solution achieves the following technical benefits: it tightly connects the anti-marine growth device with the entire ship's seawater system, achieving functional integration and synergy. The connection of the outlet pipe makes the anti-marine growth device an integral part of the ship's overall system, improving the integrity and stability of the ship's system. It also facilitates coordination and cooperation with other ship systems and, when integrated with the ship's automated control system, enables remote monitoring and operation of the anti-marine growth device.

[0017] Furthermore, the marine growth prevention device includes: a third valve, which is arranged on a side of the liquid outlet pipe close to the seawater filter.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the third valve can control the liquid outlet flow rate. At the same time, the setting of the third valve facilitates disassembly and installation. When the liquid outlet pipe or seawater filter needs to be repaired or maintained, closing the third valve can isolate the liquid outlet pipe from the seawater filter, making it convenient for staff to operate without affecting the normal operation of the seawater system of the entire ship.

[0019] Furthermore, the return pipe is arranged on the side where the seawater tank is connected to the liquid inlet pipe, and the return pipe includes a second water pump, which is used to control the flow rate of the return pipe and the direction of the seawater in the return pipe.

[0020] Compared with existing technologies, this solution achieves the following technical benefits: the second water pump generates pressure to offset external seawater pressure, allowing the anti-marine biomass to flow into the seawater tank. The return pipe precisely controls the flow rate, ensuring a stable and appropriate flow rate from the seawater tank back to the seawater filter. This helps maintain stable reaction conditions within the seawater filter and ensures continuous production of anti-marine biomass. Positioning the return pipe on the side of the liquid outlet pipe closest to the ship's seawater system further streamlines the overall layout of the system. This reduces the length and complexity of the piping, lowers fluid resistance, and improves system efficiency.

[0021] Furthermore, the return pipe may be arranged on a side of the liquid outlet pipe close to the whole ship seawater system. The liquid outlet pipe includes: a first water pump, which is arranged on a side of the liquid outlet pipe close to the whole ship seawater system.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the first water pump controls the flow rate and flow velocity on the liquid outlet side of the seawater tank, and the first water pump is arranged on the side of the liquid outlet pipe close to the seawater system of the entire ship, corresponding to the position of the return pipe, thereby reducing the cost of the entire device. At the same time, due to the pressure difference between the liquid outlet pipe and the seawater tank, the anti-marine growth material in the seawater filter can be pumped back into the seawater tank, thereby improving the efficiency of the anti-marine growth device through circulation.

[0023] Furthermore, the marine growth prevention device is provided with a fourth valve, which is arranged on a side of the liquid inlet pipe close to the seawater tank.

[0024] Compared with existing technologies, this technical solution achieves the following advantages: the fourth valve regulates the flow of seawater from the inlet pipe into the seawater filter. This allows precise control of the seawater supply based on the seawater filter's processing capacity and actual needs, ensuring a stable reaction process. Furthermore, when maintenance, cleaning, or repair of the inlet pipe or seawater tank is required, closing the fourth valve isolates the inlet pipe from the seawater tank, facilitating operations without affecting the normal operation of the seawater filter and other components.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 2 , which is a marine growth prevention device 100 for ships provided by an embodiment of the present invention, including: a seawater filter 10, used to generate marine growth prevention substances and filter seawater; a return pipe 20, one end of the return pipe 20 is detachably arranged on the seawater filter 10; a seawater tank 30, the other end of the return pipe 20 is detachably arranged on the seawater tank 30; and a liquid inlet pipe 40, one end of the liquid inlet pipe 40 is connected to the seawater filter 10, and the other end is connected to the seawater tank 30.

[0031] The return pipe 20 is detachably arranged on the seawater filter 10, which is convenient for disassembly, maintenance and installation. At the same time, by setting the return pipe 20, during the operation of the device, seawater enters the seawater filter 10 from the seawater tank 30 through the liquid inlet pipe 40. After the seawater filter 10 generates anti-marine biomass substances, part of the seawater containing the anti-marine biomass substances returns to the seawater tank 30 through the return pipe 20, realizing the recycling of materials. The anode of the seawater filter 10 adopts a Cu / Al electrode or a Cu / Fe electrode, and the cathode adopts the hull, and the anti-marine biomass substances are generated by electrolysis reaction.

[0032] Specifically, see Figure 1 and Figure 2 The return pipe 20 includes a first flange 21 and a second flange 22 . The return pipe 20 is connected to the seawater filter 10 through the first flange 21 , and is connected to the seawater tank 30 through the second flange 22 .

[0033] Flange connections are extremely stable. During vessel operation, they are subject to various vibrations and shaking. Flange connections effectively prevent the return pipe 20 from loosening or falling due to external forces, ensuring the stable operation of the entire marine growth prevention device 100. Furthermore, disassembly and maintenance are very simple, improving the maintainability of the device and reducing maintenance costs and time. Furthermore, flange connections are a common, standardized connection method that facilitates connection and integration with other equipment or components, increasing system compatibility and versatility while reducing costs.

[0034] Furthermore, the return pipe 20 is further provided with a first valve 23 , which is provided between the first flange 21 and the seawater filter 10 ; and a second valve 24 , which is provided between the second flange 22 and the seawater tank 30 .

[0035] First valve 23 and second valve 24 control the flow between return pipe 20 and seawater filter 10, and between return pipe 20 and seawater tank 30, respectively. When a reflux operation is required, the valves can be opened to allow the anti-marine biofilm material to flow from seawater filter 10 through return pipe 20 back into seawater tank 30, achieving material recycling and improving the efficiency of the anti-marine biofilm material. Furthermore, when the device is undergoing maintenance or a malfunction occurs, the valves can be closed to isolate return pipe 20 from seawater filter 10 and seawater tank 30, facilitating separate maintenance of each component without affecting the normal operation of the other components.

[0036] Further, such as Figure 1 and Figure 2 As shown, the seawater tank 30 includes a water inlet coarse filter 31 , which is disposed at the bottom of the seawater tank 30 .

[0037] The water inlet coarse filter 31 can effectively filter the seawater entering the seawater tank 30, blocking solid impurities, marine debris, and other substances in the seawater. This can prevent impurities from entering the pipeline of the marine growth prevention device 100, reduce the risk of pipeline blockage, extend the service life of the pipeline, and reduce maintenance costs.

[0038] Furthermore, the return pipe 20 further includes a nozzle 25 , which is connected to the seawater tank 30 and is disposed close to the water inlet coarse filter 31 .

[0039] The nozzle 25 can evenly spray the anti-marine growth substance flowing back from the seawater filter 10 into the seawater tank 30, especially near the position of the water inlet coarse filter 31, so that the anti-marine growth substance can be mixed with the seawater entering the seawater tank 30 more quickly, thereby improving the backflow effect of the anti-marine growth substance.

[0040] Meanwhile, the nozzle 25 has a relatively simple structure and is easy to maintain and clean. If the nozzle 25 becomes clogged or damaged, it can be easily replaced or cleaned to ensure the normal operation of the device.

[0041] Furthermore, the marine growth prevention device 100 includes: a liquid outlet pipe 50, one end of the liquid outlet pipe 50 is connected to the seawater filter 10, and the other end of the liquid outlet pipe 50 is connected to the seawater system of the entire ship.

[0042] Tightly connecting the marine growth prevention device 100 with the entire ship's seawater system achieves functional integration and synergy. The connection of the liquid outlet pipe 50 makes the marine growth prevention device 100 an integral part of the ship's overall system, improving the integrity and stability of the ship's system. Furthermore, it facilitates coordination and cooperation with other ship systems, and integrates with the ship's automated control system to enable remote monitoring and operation of the marine growth prevention device 100.

[0043] Furthermore, the marine growth prevention device 100 includes a third valve 51 , which is disposed on a side of the liquid outlet pipe 50 close to the seawater filter 10 .

[0044] The third valve 51 can control the liquid outlet flow rate. At the same time, the setting of the third valve 51 facilitates disassembly and installation. When the liquid outlet pipe 50 or the seawater filter 10 needs to be repaired or maintained, closing the third valve 51 can isolate the liquid outlet pipe 50 from the seawater filter 10, making it convenient for staff to operate without affecting the normal operation of the seawater system of the entire ship.

[0045] Furthermore, the return pipe 20 is provided at a side where the seawater tank 30 is connected to the liquid inlet pipe 40 . The return pipe 20 includes a second water pump 53 . The second water pump 53 is used to control the flow rate of the return pipe 20 and the direction of the seawater in the return pipe 20 .

[0046] The second water pump 53 is used to generate pressure to offset the external seawater pressure, allowing the anti-marine biofilm substance to flow into the seawater tank and precisely controlling the return pipe flow rate. Depending on the vessel's operating conditions and anti-marine biofilm requirements, the pump's power and speed can be adjusted to regulate the flow of seawater and anti-marine biofilm substance in the return pipe 20 for optimal anti-marine biofilm effectiveness. Furthermore, the flow rate and pressure of the seawater system can change during vessel operation. The second water pump 53 can automatically adjust the flow rate in the return pipe 20 based on actual conditions to accommodate varying operating conditions.

[0047] On the other hand, the present invention also provides another anti-marine growth device 100. Figure 2 The return pipe 20 is arranged on the side of the liquid outlet pipe 50 close to the whole ship seawater system. The liquid outlet pipe 50 includes: a first water pump 52. The first water pump 52 is arranged on the side of the liquid outlet pipe 50 close to the whole ship seawater system.

[0048] A first water pump 52 controls the flow rate and velocity at the outlet of the seawater tank 30. Positioning the first water pump 52 on the side of the outlet pipe 50 closest to the ship's seawater system eliminates the need for a water pump on the return pipe 20, saving costs. Furthermore, the return pipe 20 is positioned on the side of the outlet pipe 50 closest to the ship's seawater system. The pressure differential between the outlet pipe 50 and the seawater tank 30 allows the anti-marine growth agent in the outlet pipe 50 to flow back to the seawater tank 30 for circulation. This arrangement reduces the length and complexity of the piping, lowering installation and maintenance costs while also improving system reliability and stability.

[0049] Furthermore, the marine growth prevention device 100 is provided with a fourth valve, which is provided on a side of the liquid inlet pipe 40 close to the seawater tank 30 .

[0050] The fourth valve regulates the flow of seawater from the liquid inlet pipe 40 into the seawater filter 10. This allows precise control of the seawater supply based on the processing capacity of the seawater filter 10 and actual needs, ensuring a stable reaction process. Furthermore, when maintenance, cleaning, or repair of the liquid inlet pipe 40 or the seawater tank 30 is required, closing the fourth valve isolates the liquid inlet pipe 40 from the seawater tank 30, facilitating operations without affecting the normal operation of the seawater filter 10 or other components.

[0051] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
