Description

TECHNICAL FIELD

[0001] The present invention relates to a seaweed cultivation net cleaning device for a ship, provided with a cleaning nozzle for performing cleaning on the upper surface portion of a seaweed cultivation net to be salvaged during a netting work of towing the seaweed cultivation net to the ship, and since the cleaning nozzle is arranged at a predetermined interval along the width of the seaweed cultivation net to be salvaged, cleaning water (sea water) can be uniformly sprayed to the entire area of the seaweed cultivation net even in a low water pressure, and the present invention includes an upper side cleaning nozzle line and a lower side cleaning nozzle line provided with the cleaning nozzle, so that not only the upper surface portion of the seaweed cultivation net to be salvaged but also the lower surface portion of the seaweed cultivation net to be salvaged can be uniformly cleaned during the netting work of towing the seaweed cultivation net to the ship, thereby maximizing the cleaning performance, and the seaweed cultivation net under the water surface can be prevented from contacting the bow portion of the ship during the netting work of towing the seaweed cultivation net to the ship for cleaning the seaweed cultivation net. BACKGROUND

[0002] Generally, seaweed of the seaweed class is a kind of organism growing on the upper portion of the intertidal zone, which is submerged at high tide and exposed at low tide, and in the past, a bamboo curtain was used for natural seedling cultivation, but recently, artificial seedling collection using a trawl net made of synthetic fiber is mostly used, for example, a cast net and a reverse type sticky net are currently developed.

[0003] On the other hand, when seaweed is cultivated using a seaweed cultivation net, since seaweed seeds attached to the seaweed cultivation net need to be cultivated in a waterlogged state at high tide, foreign matters such as attached foreshore soil will become a factor inhibiting the growth of seaweed.

[0004] Therefore, during a netting work of towing a seaweed cultivation net to a ship for collection of seaweed using a conventional seaweed collector (Patent Document 1) provided on the ship, a worker needs to separately operate a sprayer to clean the seaweed cultivation net.

[0005] On the other hand, when the seaweed cultivation net located relatively far from the worker needs to be cleaned, although the worker can clean the seaweed cultivation net by increasing the water pressure, since seaweed seeds attached to the seaweed cultivation net have very small rooting ability, there is a problem that the production amount is reduced due to the detachment or damage of the seaweed seeds.

[0006] Also, during a netting work of towing a seaweed cultivation net to a ship for collection of seaweed using a conventional seaweed collector, when a worker separately operates a sprayer to clean the seaweed cultivation net, since only foreign matters on the upper surface portion of the seaweed cultivation net can be cleaned, there is a problem that the cleaning performance is halved.

[0007] In addition, there is a problem in that, when the netting work of towing the seaweed farming net to the hull for the use of the existing seaweed collector, if the seaweed farming net under the water surface contacts with the bow portion of the hull when the worker alone operates the sprayer to clean the seaweed farming net, the seaweed seeds attached to the seaweed farming net are detached or damaged.

[0030] Best practice

[0031] This invention relates to a cleaning device for seaweed farming nets used on ship hulls. It includes cleaning nozzles for cleaning the upper surface of the seaweed farming net during the retrieval process after towing it onto the ship. Because the cleaning nozzles are spaced at predetermined intervals along the width of the seaweed farming net, even under low water pressure, cleaning water (seawater) can be evenly sprayed onto the entire area of ​​the seaweed farming net to guide the cleaning. Furthermore, this invention includes upper and lower cleaning nozzle pipelines for the aforementioned cleaning nozzles. Therefore, during the retrieval process after towing the seaweed farming net onto the ship hull, not only the upper surface of the seaweed farming net to be retrieved can be cleaned evenly, but also the lower surface can be cleaned evenly. This maximizes cleaning performance. In the process of cleaning seaweed farming nets and towing them onto a ship for hauling them onto the hull, the seaweed farming nets below the water surface can be kept out of contact with the bow part of the ship. The seaweed farming net cleaning device for the ship hull of the present invention includes: a top surface cleaning component 100, located on the hull S and disposed on the upper side of the seaweed farming net to be hauled, equipped with a plurality of cleaning nozzles 111 and 121 for cleaning the upper surface of the seaweed farming net to be hauled, the plurality of cleaning nozzles 111 and 121 being spaced apart along the width of the seaweed farming net to be hauled; and a bottom surface cleaning pipe 200, located on the hull S and disposed on the lower side of the seaweed farming net to be hauled, equipped with a plurality of cleaning nozzles 210 for cleaning the lower surface of the seaweed farming net to be hauled, the plurality of cleaning nozzles 210 being spaced apart along the width of the seaweed farming net to be hauled. Detailed Implementation

[0032] The structure and function of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Before that, it should be understood that various modifications can be made to the present invention, and various implementation methods can be used. The following embodiments are only used to describe the present invention in detail and are not intended to limit the present invention to a specific implementation method, including all modifications, equivalent technical solutions and alternative technical solutions derived based on the ideas and technical scope of the present invention.

[0033] Furthermore, for ease of explanation, structural elements in the various figures may be shown enlarged or simplified; however, this should not be interpreted as limiting the scope of the invention. The same reference numerals are used wherever possible to perform the same function. Moreover, the terminology used in this specification is for illustrative purposes only and does not limit the scope of the invention. Unless otherwise expressly indicated in the context, singular expressions include plural expressions.

[0034] like Figures 1 to 7As shown, the seaweed farming net cleaning device for ship hulls of the present invention is generally composed of a cleaning component 100 on the upper surface of the net and a cleaning pipe 200 on the lower surface of the net.

[0035] First, the surface cleaning component 100 is located on the hull S and is configured on the upper side of the seaweed farming net to be salvaged. It is equipped with multiple cleaning nozzles 111 and 121 for cleaning the upper surface of the seaweed farming net to be salvaged. The multiple cleaning nozzles 111 and 121 can be arranged at intervals along the width of the seaweed farming net to be salvaged.

[0036] To improve cleaning performance, the surface-side cleaning component 100 with the above structure can perform a second cleaning after the first cleaning.

[0037] Therefore, as a specific structure of the surface cleaning component 100, the surface cleaning pipe 110 has multiple cleaning nozzles 111 arranged at specified intervals along the width of the seaweed farming net to be salvaged on the lower side, which can spray cleaning water to perform the first cleaning of the upper surface of the seaweed farming net to be salvaged.

[0038] The multiple cleaning nozzles 111 are spaced 14cm apart, which improves cleaning efficiency even when the sprayed cleaning water is at low pressure.

[0039] Furthermore, the cleaning nozzle 111 of the cleaning component 100 on the surface of the net has a circular variable cross section (van) on its inner diameter surface, so that the sprayed cleaning water can rotate into a circular variable cross section (van) and be sprayed out in a cone shape. As a result, the cleaning water contacts the surface of the seaweed cultivation net in the form of droplets.

[0040] Furthermore, a rear cleaning pipe 120 is provided at a predetermined distance from the front cleaning pipe 110 on the surface of the net. Multiple cleaning nozzles 121 are arranged at predetermined intervals on the lower side of the rear cleaning pipe 120 along the width of the seaweed farming net to be salvaged, so as to perform a second cleaning on the upper surface of the seaweed farming net to be salvaged. Thus, cleaning water can be sprayed to perform the cleaning function on the upper surface of the seaweed farming net to be salvaged again.

[0041] Multiple cleaning nozzles 121 are positioned at intersections with the nozzles of the front cleaning pipe 110 on the upper surface, thereby improving cleaning efficiency.

[0042] On the other hand, connecting brackets 130 and 140 for secure fixing are connected to both sides of the front cleaning tube 110 and the rear cleaning tube 120 on the surface of the web. The connecting bracket 130 connects one side of the front cleaning tube 110 and the rear cleaning tube 120 on the surface of the web, and the other connecting bracket 140 connects the other side of the front cleaning tube 110 and the rear cleaning tube 120 on the surface of the web.

[0043] Furthermore, one end of the front cleaning pipe 110 and the rear cleaning pipe 120 on the surface of the net are respectively connected to one end of each hose, and each hose is connected to each branch pipe of the distributor 101, which can be pumped by the ship's S engine to supply seawater as cleaning water.

[0044] In this case, a first regulating valve 102 is provided on the branch pipe connected to the front cleaning pipe 110 on the surface of the net to regulate the inflow of cleaning water, and a second regulating valve 103 is provided on the branch pipe connected to the rear cleaning pipe 120 on the surface of the net to regulate the inflow of cleaning water.

[0045] The aforementioned cleaning pipe 200 on the lower surface of the net is located on the hull S and is configured on the lower side of the seaweed farming net to be salvaged. It is equipped with multiple cleaning nozzles 210 for cleaning the lower surface of the seaweed farming net to be salvaged. The multiple cleaning nozzles 210 can be arranged at intervals along the width of the seaweed farming net to be salvaged.

[0046] The cleaning nozzle 210, located on the cleaning pipe 200 on the lower surface of the mesh, has an inner diameter width of approximately 2.8 mm to 13.2 mm, allowing the sprayed cleaning water to be ejected in a planar fan shape. This effectively prevents cleaning water from splashing out of the cover 300 from the top.

[0047] On the other hand, one end of the underside cleaning pipe 200 is connected to one end of the hose, and the hose is connected to other branches of the distributor 101, which can be pumped by the ship's S engine to supply seawater as cleaning water.

[0048] In this case, a third regulating valve 104 is installed on the branch pipe connected to the cleaning pipe 200 on the lower surface of the net to regulate the inflow of cleaning water.

[0049] In the cleaning pipe 200 on the lower surface of the net with the above structure, since multiple cleaning nozzles 210 are protruding and connected to the upper side, when the seaweed farming net to be salvaged sags, the protruding multiple cleaning nozzles 210 may damage the seaweed farming net.

[0050] To prevent this phenomenon, a seaweed farming net anti-damage reinforcing rod 230 is connected and fixed to both sides of the multiple cleaning nozzles 210 that protrude upward from the cleaning pipe 200 on the lower surface of the net. The seaweed farming net anti-damage reinforcing rod 230 is connected and fixed in such a way that its height is greater than the height of the cleaning nozzles 210.

[0051] Preferably, the seaweed farming net anti-damage reinforcing rod 230 includes a support reinforcing rod 231, which is arranged at specified intervals to connect and fix the seaweed farming net anti-damage reinforcing rod 230 to the cleaning pipe 200 on the lower surface of the net.

[0052] On the other hand, when the lower surface of the seaweed farming net to be salvaged is cleaned through the cleaning pipe 200 on the lower surface side of the net, as cleaning water is sprayed through multiple cleaning nozzles 210 protruding upward from the cleaning pipe 200 on the lower surface side of the net, the cleaning water is scattered in all directions toward the hull S, which may affect the crew of the ship.

[0053] To prevent this from happening, a cover 300 is attached to the upper part of the surface cleaning component 100 to prevent the cleaning water sprayed upward from the cleaning nozzle 210 of the underside cleaning pipe 200 from spilling out.

[0054] The cover 300 is a semi-cylindrical body made of flexible plastic material, which can surround the upper part of the cleaning component 100 on the upper surface of the net.

[0055] Furthermore, the cover 300 can be detachably fixed to the cleaning component 100 on the surface of the net using a fixing strap. In addition to the fixing strap, various fixing methods such as cable ties, buttons, hooks, and zippers can be selected.

[0056] Furthermore, in order to prevent damage to the seaweed farming net during the cleaning process, after cleaning is completed, in order to allow the seaweed farming net to detach smoothly and prevent the two sides of the cover 300 from being rolled into the interior of the cleaning component 100 on the upper surface of the net, a reinforcing rod 150 for preventing the cover from entering is connected and fixed to the outside of the front cleaning pipe 110 on the upper surface of the net, and a reinforcing rod 160 for preventing the cover from entering is connected and fixed to the outside of the rear cleaning pipe 120 on the upper surface of the net. Then, the fixing straps can be used to fix each edge of the cover 300 around the reinforcing rod 150 for preventing the cover from entering on one side and the reinforcing rod 160 for preventing the cover from entering on the other side.

[0057] Preferably, the aforementioned reinforcing rod 150 for preventing the cover from entering on one side and the reinforcing rod 160 for preventing the cover from entering on the other side include supporting reinforcing rods 151 and 161, which are arranged at predetermined intervals and are used to connect and fix the aforementioned reinforcing rod 150 for preventing the cover from entering on one side and the reinforcing rod 160 for preventing the cover from entering on the other side to the cleaning pipe 200 on the lower surface of the net.

[0058] Furthermore, if a single retrieval operation for cleaning seaweed farming nets is completed, the cleaned seaweed farming nets need to be removed and other seaweed farming nets need to be connected. Therefore, in the seaweed farming net cleaning device for ship hulls of the present invention, the cleaning component 100 on the upper surface of the net and the cleaning pipe 200 on the lower surface of the net located around the rear end of the ship hull S need to be movable.

[0059] Therefore, a side hole S1 is formed through one side of the inner side of the hull S, and another side hole S2 is formed through the other side of the inner side of the hull S.

[0060] Furthermore, in the two connecting brackets 130 and 140 that connect the front cleaning pipe 110 on the surface of the net and the rear cleaning pipe 120 on the surface of the net, the upper end of the rotating rod 410 is fixed to the connecting bracket 140 at the rear end, and the lower part of the rotating rod 410 is inserted into the hole S2 on the other side in a rotatable manner.

[0061] Furthermore, one side of the underside cleaning pipe 200 is fixedly connected to the lower side of the rotating rod 410. In this case, since one end of the underside cleaning pipe 200 is connected to the hose, the side of the underside cleaning pipe 200 and the lower side of the rotating rod 410 can be connected by the connector 411.

[0062] Furthermore, the lower part of the support rod 420 is inserted into a side hole S1, and a locking member 421 is attached to the upper part of the support rod 420. The locking member 421 can be hemispherical.

[0063] Furthermore, in the two connecting brackets 130 and 140 that connect the front cleaning pipe 110 on the surface of the net and the rear cleaning pipe 120 on the surface of the net, the front connecting bracket 130 is connected to one end of the hanging rod 430, and the other end of the hanging rod 430 can be locked in the locking member 421 to restrict rotation.

[0064] Therefore, if the ship's crew rotates counterclockwise while holding the hanging rod 430, the cleaning component 100 on the upper surface of the net and the cleaning pipe 200 on the lower surface of the net will rotate about the rotating rod 410 as an axis, thus opening.

[0065] On the other hand, a pulley 220 can be connected to the other end of the cleaning pipe 200 on the lower surface of the net so that opening can be achieved smoothly when the net is opened.

[0066] Furthermore, in order to guide the successful salvage by isolating the seaweed farming net to be salvaged from the bow of the ship and to further prevent the seaweed seeds attached to the seaweed farming net from falling off or being damaged, the seaweed farming net cleaning device for the ship's hull of the present invention may include an anti-contact hull end roller 500 located at the bow of the ship's hull S, used to isolate the seaweed farming net to be salvaged from the bow of the ship's hull S, and is provided with an end roller 510, which rotates due to the contact friction of the seaweed farming net to be salvaged.

[0067] The specific structure of the aforementioned anti-contact hull end roller 500 includes: an end roller 510, which contacts the seaweed farming net to be salvaged, with fixed shafts 511 and 512 extending and protruding from both sides; a side-mounted idler component 520, equipped with a ball bearing, allowing the fixed shaft 511 of the end roller 510 to be inserted inside and idle; a side-mounted idler component 530, equipped with a ball bearing, allowing the fixed shaft 512 of the end roller 510 to be inserted inside and idle; a side-mounted sliding component 540, including a side-mounted vertical plate 541, a side-mounted horizontal plate 542, and a side-mounted movable pin 543, wherein the side-mounted vertical plate 541 has the side-mounted idler component 520 fixed on its front surface, the side-mounted horizontal plate 542 is formed by bending and extending from the side-mounted vertical plate 541, and the side-mounted movable pin 543 protrudes from both sides of the end of the side-mounted horizontal plate 542; and a side-mounted sliding component 550. The system includes a vertical plate 551, a horizontal plate 552, and a movable pin 553. The vertical plate 551 has a free-spinning component 530 fixed to its front surface. The horizontal plate 552 extends from the vertical plate 551. The movable pin 553 protrudes from both ends of the horizontal plate 552. A movable guide component 560 is fixed to one side of the bow surface of the hull S. It has long grooves 561 on both sides for guiding the movable pin 543 of the horizontal plate 542 to move horizontally forward and backward. A movable guide component 570 is fixed to the other side of the bow surface of the hull S. It has long grooves 571 on both sides for guiding the movable pin 553 of the horizontal plate 552 to move horizontally forward and backward.

[0068] Therefore, during the hauling-in of the seaweed farming net, if the moving pins 543 and 553 respectively provided on one side sliding member 540 and the other side sliding member 550 are moved along the forward direction of the moving grooves 561 and 571 respectively formed on one side moving guide member 560 and the other side moving guide member 570, then the horizontal plates 542 and 552 respectively provided on one side sliding member 540 and the other side sliding member 550 are located on the upper surface of the bow of the hull S, while the vertical plates 541 and 551 are located on the side of the bow of the hull S.

[0069] In this situation, during the hauling-in of the seaweed farming net, as it sways with the swaying seawater surface, the end roller 510 located at the rear of the hull S can move to the upper surface of the bow of the hull S.

[0070] To prevent this phenomenon, fixed grooves 562 and 572 can be formed on one side of the moving guide member 560 and the other side of the moving guide member 570. These grooves are formed closer to the bow side of the hull S than the moving long grooves 561 and 571. When the horizontal plates 542 and 552 are located on the upper surface of the bow of the hull S and the vertical plates 541 and 551 are located on the side of the bow of the hull S, they are formed at a higher position than the horizontal plates 542 and 552.

[0071] In this case, preferably, the fixing grooves 562 and 572 should be formed at a height position slightly greater than the thickness of the horizontal plates 542 and 552.

[0072] Therefore, as the fixing pins 563 and 573 are inserted and fixed in the fixing grooves 562 and 572 respectively formed on one side of the moving guide member 560 and the other side of the moving guide member 570, during the seaweed farming net hauling operation, even if the sea surface sways, the fixing pins 563 and 573 can prevent the level plate 542 and 552 from swaying in advance, thereby preventing the end roller 510 from moving to the upper surface of the bow of the hull S in advance.

[0073] Meanwhile, during the hauling-in of the seaweed farming net, the end roller 510 may come into contact with the bow side of the hull S due to the swaying seawater surface.

[0074] As described above, if the end roller 510 comes into contact with the bow side of the hull S, the idling of the end roller 510 will be suppressed, which will have an adverse effect on the seaweed spores that are taking root in the seaweed farming net to be harvested. Therefore, preferably, the end roller 510 should always maintain a distance from the bow side of the hull S.

[0075] For this purpose, a buffer member 580 for maintaining the gap is also included, which is fixed between the end roller 510 and the bow side of the hull S in a detachable manner, such that when the horizontal plates 542 and 552 are located on the upper surface of the bow of the hull S and the vertical plates 541 and 551 are located on the bow side of the hull S, the end roller 510 is separated from the bow side of the hull S.

[0076] The buffer component 580 for maintaining the interval can be provided on only one side of the vertical plates 541 and 551 on both sides. Preferably, it should be provided on both vertical plates 541 and 551 on both sides respectively.

[0077] The aforementioned buffer member 580 for maintaining the interval is provided with a fixing pin in the buffer part (made of rubber material) that has a buffering function. As a fixing groove is formed on the bow side of the hull S, the aforementioned fixing pin can be inserted and fixed in the formed fixing groove.

[0078] While specific embodiments of the present invention have been described above with reference to the accompanying drawings, it should be understood that those skilled in the art can make various modifications and variations within the scope of the inventive concept without departing from the scope of protection of the present invention.

[0079] Industrial availability

[0080] The seaweed cultivation net cleaning device for ship hulls of the present invention is equipped with cleaning nozzles. During the net retrieval process of towing the seaweed cultivation net onto the ship hull, these nozzles are used to clean the upper surface of the seaweed cultivation net to be retrieved. Since the cleaning nozzles are arranged at predetermined intervals along the width of the seaweed cultivation net to be retrieved, even under low water pressure, cleaning water (seawater) can be sprayed evenly onto the entire area of ​​the seaweed cultivation net. This minimizes the loss or damage of seaweed seeds rooted in the seaweed cultivation net. Furthermore, the present invention includes the aforementioned cleaning nozzles... The cleaning nozzle has upper and lower cleaning nozzle lines, so during the retrieval process of towing the seaweed farming net onto the hull, it can not only evenly clean the upper surface of the seaweed farming net to be retrieved, but also evenly clean the lower surface of the seaweed farming net to be retrieved. This maximizes the cleaning performance. During the retrieval process of towing the seaweed farming net onto the hull for cleaning, the seaweed seeds attached to the seaweed farming net can be prevented from falling off or being damaged by isolating the seaweed farming net below the water surface from contact with the bow of the hull.
