Description

Technical Field

[0001] This utility model belongs to the field of seawater pump technology, specifically relating to a seawater pump that resists marine organism attachment. Background Technology

[0002] Seawater pumps are suitable for fire fighting, equipment cooling, and seawater desalination on offshore platforms. They can also be used for heating in ground source heat pump air conditioning in coastal areas, for all seawater lifting purposes, for seaside square fountain landscapes, and for mariculture. This equipment is low in noise, highly efficient, and saves energy.

[0003] However, existing seawater pumps are installed in marine environments for extended periods, where marine organisms can attach to the equipment, causing pump jamming and cable severance. To reduce the serious harm caused by marine organisms to seawater pumps, the bubble barrier method is currently used. This was the earliest method, but its effectiveness is not very reliable. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a seawater pump that resists the attachment of marine organisms, which can generate a magnetic field to prevent surrounding marine organisms from attaching to the equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a seawater pump for resisting marine organism attachment, including a pump body, a flow guide shroud, and an electrode cover assembly. The flow guide shroud is connected to the pump body, and the electrode cover assembly is assembled at the connection between the pump body and the flow guide shroud. Two copper busbars are electrically connected to the electrode cover assembly. The electrode cover assembly includes an aluminum anode block and a copper anode block. The aluminum anode block and the copper anode block are fitted together and wrapped around the connection between the pump body and the flow guide shroud. The two copper busbars are electrically connected to the aluminum anode block and the copper anode block, respectively.

[0006] The end of the flow guide shroud away from the pump body is equipped with a water inlet mesh filter cover.

[0007] Both the aluminum anode block and the copper anode block are fitted with hose clamps.

[0008] Motor cover baffles are installed on both sides of the electrode cover assembly facing the pump body and the flow guide shroud, respectively.

[0009] A cleaning wheel is movably installed inside the flow guide. The cleaning wheel includes a magnetic stainless steel ring and a brush ring. The stainless steel ring is raised and lowered inside the flow guide, and the brush ring is sleeved on the outer ring of the stainless steel ring.

[0010] A protective cover is threadedly installed at the bottom of the water inlet mesh filter cover, and the stainless steel ring is placed on the protective cover. The protective cover is provided with a traction spring connected to the stainless steel ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention relates to a seawater pump designed to prevent marine organism adhesion. The motor is protected by a motor cover. Two copper busbars connect the electrical wires, allowing the aluminum and copper anode blocks to work together to generate a magnetic field. When the copper anode block is energized, it electrolyzes the seawater, causing it to lose electrons and become copper ions, which inhibit microbial growth. Meanwhile, the aluminum anode block loses electrons and is oxidized in the electrolytic environment, generating aluminum ions. These aluminum ions combine with hydroxide ions in the seawater to form aluminum hydroxide flocs, creating a protective film that prevents marine organisms from adhering to the equipment. Furthermore, the copper ions diffuse freely, filling the entire flow guide sleeve and pump inlet, and remain inside the flow guide sleeve with the aluminum hydroxide flocs, inhibiting the growth of marine organisms within.

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-3As shown, this embodiment provides a seawater pump resistant to marine organism attachment, including a pump body 1, a flow guide 2, and an electrode cover assembly 3. The flow guide 2 is connected to the pump body 1. The electrode cover assembly 3 is mounted at the connection between the pump body 1 and the flow guide 2. Two copper busbars 4 are electrically connected to the electrode cover assembly 3. The electrode cover assembly 3 includes an aluminum anode block 6 and a copper anode block 7, which are fitted together and wrap around the connection between the pump body 1 and the flow guide 2. The two copper busbars 4 are electrically connected to the aluminum anode block 6 and the copper anode block 7, respectively, and the outer wall of the pump body 1 serves as the cathode. Specifically, motor cover baffles 9 are installed on both sides of the electrode cover assembly 3 facing the pump body 1 and the flow guide 2. The motor is protected by the motor cover baffles 9. Two copper busbars 4 connect the wires, allowing the aluminum anode block 6 and the copper anode block 7 to work together to generate a magnetic field. When the copper anode block 7 is energized, it electrolyzes seawater, causing it to lose electrons and become copper ions, which inhibit microbial growth. Meanwhile, the aluminum anode block 6 loses electrons and is oxidized in the seawater electrolysis environment, generating aluminum ions. These aluminum ions combine with hydroxide ions in the seawater to form aluminum hydroxide flocs, creating a protective film that prevents surrounding marine organisms from adhering to the equipment. Furthermore, the copper ions diffuse freely, filling the entire flow guide sleeve and pump inlet, and remain inside the flow guide sleeve with the aluminum hydroxide flocs, inhibiting the growth of marine organisms within.

[0019] Furthermore, an inlet mesh filter cover 5 is installed at the end of the flow guide shroud 2 away from the pump body 1. Filtration is performed through the inlet mesh filter cover 5.

[0020] Furthermore, both the aluminum anode block 6 and the copper anode block 7 are fitted with hose clamps 8. The hose clamps 8 secure the aluminum anode block 6 and the copper anode block 7, and also facilitate disassembly and replacement.

[0021] Furthermore, a cleaning wheel is movably installed inside the flow guide shroud 2. The cleaning wheel includes a magnetic stainless steel ring 10 and a brush ring 11. The stainless steel ring 10 is raised and lowered inside the flow guide shroud 2, and the brush ring 11 is fitted onto the outer ring of the stainless steel ring 10. The stainless steel ring 10 is made of martensitic stainless steel. Specifically, a protective cover 12 is threadedly installed below the water inlet mesh filter cover 5. The stainless steel ring 10 is placed on the protective cover 12, and the protective cover 12 is equipped with a traction spring 13 connected to the stainless steel ring 10. The magnetic field generated when the electrode cover assembly 3 is working attracts the stainless steel ring 10 to rise, thereby cleaning the inside of the flow guide shroud 2 where the brush ring 11 is fitted. After the electrode cover assembly 3 stops working, it is pulled back by the traction spring 13 to clean the inside of the flow guide shroud 2 again. The entire assembly can be disassembled by rotating the protective cover 12 for easy replacement.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
