Description

Technical Field

[0001] The utility model relates to the technical field of ship anti-marine organism equipment, in particular to an anti-marine organism device for a tugboat. Background Art

[0002] The seawater cooling system of the tugboat is an open cooling system, and it is extremely easy for marine organisms to attach and grow in the seawater cooling system, thus causing blockage of the cooling water pipeline, resulting in insufficient equipment cooling and high temperature. Especially along the coast of the Bohai Bay, due to the serious eutrophication of the seawater at the Yellow River estuary, the growth of marine organisms is rampant. The seawater cooling system of the tugboat is blocked many times every year due to the growth of marine organisms. The equipment stops due to high temperature and is forced to stop for cleaning, seriously delaying production. The existing patent with the patent number CN2341891Y discloses an anti-marine organism device inside a marine ship seawater cooling pipe system. The copper anode and the aluminum anode of this device are connected to the same conductor. The copper anode electrolyzes in seawater to generate trace copper ions. When the seawater containing these trace copper ions flows through the seawater pipe system, it can effectively inhibit the growth of marine organisms therein, thus playing an anti-blocking role; after the aluminum anode electrolyzes, a small amount of aluminum hydroxide precipitate is generated. As the electrolysis time lengthens, these precipitates adhere to the inner wall of the seawater pipe system, forming a very thin protective layer, thereby preventing the generation of marine organisms and playing an anti-corrosion role. Since the copper anode and the aluminum anode of this device are connected to the same conductor, and the electrolysis consumption rates of the copper anode and the aluminum anode are different, it is very inconvenient to replace the copper anode and the aluminum anode separately, and it is impossible to control the electrolysis current of the copper anode and the aluminum anode respectively according to the area where the tugboat is traveling, and it is very difficult to ensure the stability of the anti-marine organism device. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-marine organism device for a tugboat to overcome the problems existing in the existing equipment.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an anti-marine organism device for a tugboat, which includes a sea chest, an electrolysis electrode group and a detection device arranged in the sea chest, and a junction box and a control box connected to the electrolysis electrode group and the detection device. The electrolysis electrode group includes a first electrolysis electrode group and a second electrolysis electrode group. The first electrolysis electrode group is provided with a copper anode, and the second electrolysis electrode group is provided with an aluminum anode. The detection device includes a salinity detector and an ion detector.

[0005] On the basis of the above technical solution, the utility model can also be improved as follows:

[0006] As a further improvement of the above technical solution, the sea chest includes a high-level sea chest and a low-level sea chest. The high-level sea chest is located above the low-level sea chest. The high-level sea chest and the low-level sea chest are respectively arranged in the high and low sea valves of the tugboat engine room. An electrolysis electrode group and a detection device are arranged in both the high-level sea chest and the low-level sea chest. The electrolysis electrode group and the detection device are both connected to one end of a junction box through a marine cable, and the other end of the junction box is connected to a control box through a marine cable.

[0007] As a further improvement of the above technical solution, the control box includes an electric control box and a power supply. The electric control box is connected to the power supply through a marine cable. The junction box is connected to the electric control box, and the power supply uses an alternating current power supply.

[0008] As a further improvement of the above technical solution, the first electrolysis electrode group includes a base and an anode conductor. The base is fixed to the sea chest by bolts. The base is used as a cathode. A dust-proof cover is connected to the base by bolts. A wiring cavity is formed between the base and the dust-proof cover.

The anode conductor is arranged inside the base. One end of it extends into the wiring cavity and is connected to the watertight cable joint, and the other end is connected with a copper anode on the outside.

[0009] As a further improvement of the above technical solution, the second electrolysis electrode group includes a base as a cathode and an anode conductor. An aluminum anode is connected to the anode conductor.

[0010] As a further improvement of the above technical solution, the base is a flange-type base. The material of the base is iron, and the material of the anode conductor is copper. Epoxy resin is arranged between the anode conductor and the base.

[0011] The beneficial effects of the present utility model are as follows: Compared with the prior art, the anti-marine organism device of the tugboat of the present utility model detects the seawater salinity in the sea chest through a salinity detector and feeds it back to the control box. The control box adaptively adjusts the magnitude of the current output to the electrolysis electrode group according to a specific seawater salinity range, ensuring the stability of the operation of the anti-marine organism device of the tugboat in the case of unstable seawater salinity in coastal waters. In addition, the copper anode and the aluminum anode are respectively arranged in the first electrolysis electrode group and the second electrolysis electrode group. Such an arrangement facilitates the replacement of the copper anode and the aluminum anode, and can control the electrolysis current of the copper anode and the aluminum anode respectively. By detecting the concentrations of copper ions and aluminum ions in the seawater through an ion detector and feeding them back to the control box, it can be detected in real time whether the copper anode and the aluminum anode need to be replaced, further ensuring the stability of the operation of the anti-marine organism device.

[0019] Such as Figure 1, Figure 2 As shown in Figure 2 , a kind of anti-marine organism device for towing wheels provided by a preferred embodiment of the present utility model includes a subsea valve box 1, an electrolytic electrode group 2, a detection device 3, a junction box 4 and a control box 5.

[0020] The subsea valve box 1 is installed on the towing wheel and can communicate with external seawater. The subsea valve box 1 includes a high-level subsea valve box 11 and a low-level subsea valve box 12. The high-level subsea valve box 11 is located above the low-level subsea valve box 12. The high-level subsea valve box 11 and the low-level subsea valve box 12 are respectively arranged in the high and low level subsea doors of the towing wheel engine room. A group of electrolytic electrode group 2 and a detection device 3 are arranged in the high-level subsea valve box 11. Both the electrolytic electrode group 2 and the detection device 3 are connected to one end of the junction box 4 through marine cables. The other end of the junction box 4 is connected to the control box 5 through a marine cable. Among them, the control box 5 includes an electric control box 51 and a power supply 52. The electric control box 51 is connected to the power supply 52 through a marine cable. The junction box 4 is connected to the electric control box 51. The power supply 52 can supply power to the detection device 3 and the electric control box 51 to ensure the normal operation of the detection device 3 and the electric control box 51. The power supply 52 uses an alternating current power supply. Similarly, a group of electrolytic electrode group 2 and a detection device 3 are also arranged in the low-level subsea valve box 12. Both the electrolytic electrode group 2 and the detection device 3 are connected to one end of the junction box 4 through marine cables. The other end of the junction box 4 is connected to the electric control box 51 through a marine cable.

[0021] The electrolytic electrode group 2 includes a first electrolytic electrode group 21 and a second electrolytic electrode group 22. The first electrolytic electrode group 21 includes a base 211, an anode conductor 213 and a copper anode 215. The base 211 is fixed to the subsea valve box 1 by bolts. The base 211 is a flange-type base and is used as a cathode. The material of the base 211 can be iron. A dust-proof cover 212 is connected to the base 211 by bolts. A wiring cavity is formed between the base 211 and the dust-proof cover 212. A watertight cable joint 214 is led out from the wiring cavity. The base 211 and the anode conductor 213 are connected to the watertight cable joint 214 through wires. The material of the anode conductor 213 can be copper. The anode conductor 213 is arranged in the base 211. One end of it extends into the wiring cavity and is connected to the watertight cable joint 214 to provide electrolytic current for the copper anode 215. The other end of it is connected to the copper anode 215 on the outside. The anode conductor 213 and the base 211 can be insulated and waterproof sealed with epoxy resin 216. The second electrolytic electrode group 22 has the same structure as the first electrolytic electrode group 21, and the only difference is that: the second electrolytic electrode group 22 includes a base 211 as a cathode, an anode conductor 213 and an aluminum anode connected to the anode conductor 213.

[0022] The copper anode 215 electrolyzes in seawater to produce trace amounts of copper ions. When seawater containing these trace amounts of copper ions flows through the seawater piping system, it can effectively inhibit the growth of marine organisms therein, thereby playing an anti-blocking role; after electrolysis, the aluminum anode generates a small amount of aluminum hydroxide precipitate. As the electrolysis time lengthens, these precipitates adhere to the inner wall of the seawater piping system, forming a very thin protective layer, which further prevents the generation of marine organisms and plays an anti-corrosion role.

[0023] The copper anode 215 and the aluminum anode are respectively arranged in the first electrolysis electrode group 21 and the second electrolysis electrode group 22. Such an arrangement facilitates the replacement of the copper anode 215 and the aluminum anode, and can respectively control the electrolysis current of the copper anode 215 and the aluminum anode, ensuring the stability of the operation of the anti-marine organism device.

[0024] The detection device 3 includes a salinity detector 31 and an ion detector 32. The salinity detector 31 is used to detect the salinity of seawater. By detecting the range of the salinity of seawater in the sea bottom valve box 1, the area where the tugboat is traveling can be clearly known; since the average salinity of seawater is 3.5%, considering that the salinity range in coastal waters is 2%-3%, the salinity detector 31 can automatically adjust the magnitude of the current output to the electrolysis electrode group 2. The ion detector 32 is used to detect the concentration of copper ions and aluminum ions in seawater. By detecting the concentration of copper ions and aluminum ions, the working efficiency of the copper anode 215 and the aluminum anode can be judged, and it can be detected in real time whether the copper anode 215 and the aluminum anode need to be replaced, and the replacement work can be completed without affecting the normal operation of the tugboat.

[0025] The working principle of this embodiment is as follows: The electrolysis electrode group 2 and the detection device 3 are successively installed in the sea bottom valve box 1 and connected to the control box 5. The power supply 52 is turned on. At this time, the salinity detector 31 detects the salinity of seawater in the sea bottom valve box 1. When the salinity detector 31 detects the seawater salinity and feeds it back to the electric control box 51, when the electric control box 51 judges that the seawater salinity is lower than 1.5%, the currents of the copper anode 215, the aluminum anode and the cathode of the electrolysis electrode group 2 are controlled to be 0A. The ion detector 32 detects the concentration of copper ions and aluminum ions in seawater and feeds it back to the electric control box 51. By detecting the concentration of copper ions and aluminum ions, the working efficiency of the copper anode 215 and the aluminum anode is judged, and it can be detected in real time whether the copper anode 215 and the aluminum anode need to be replaced, and the replacement work can be completed without affecting the normal operation of the tugboat.

[0026] Compared with the prior art, the anti-marine organism device of the utility model detects the seawater salinity in the sea chest 1 through the salinity detector 31 and feeds it back to the control box 5. The control box 5 adaptively adjusts the magnitude of the current output to the electrolytic electrode group 2 according to the specific seawater salinity range, ensuring the stability of the anti-marine organism device of the tugboat in the case of unstable seawater salinity in coastal waters. In addition, the copper anode 215 and the aluminum anode are respectively arranged in the first electrolytic electrode group 21 and the second electrolytic electrode group 22. This setting facilitates the replacement of the copper anode 215 and the aluminum anode, and can control the electrolytic current of the copper anode 215 and the aluminum anode respectively. By detecting the concentrations of copper ions and aluminum ions in seawater through the ion detector 32 and feeding them back to the control box 5, it can be detected in real time whether the copper anode 215 and the aluminum anode need to be replaced, further ensuring the stability of the anti-marine organism device.
