Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of rather than all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0038] The following describes a fishing net cleaning ship according to an embodiment of this application with reference to the accompanying drawings.

[0039] As Figures 1 - 16 shown, the fishing net cleaning ship according to an embodiment of this application includes: a cleaning ship body 100, a recovery winch assembly 200, a tow hook assembly 300, and a fishing net sorting assembly 400. The cleaning ship body 100 is used to load the recovery winch assembly 200, the tow hook assembly 300, and the fishing net sorting assembly 400. The recovery winch assembly 200 is used to drive the tow hook assembly 300 to drag the fishing net for recovery and cleaning. The tow hook assembly 300 is used to hook the fishing net, and the fishing net sorting assembly 400 is used to gather the scattered fishing net.

[0040] As Figure 2It is shown that the recovery winch assembly 200 is fixedly connected to the cleaning ship body 100 near the middle position, and the recovery winch assembly 200 includes a mounting base 210, a driving member 220, a slewing bearing 230 and a recovery winch 240. The mounting base 210 is fixedly connected to the cleaning ship body 100 near the middle position, wherein the mounting base 210 is fixedly connected to the cleaning ship body 100 near the middle position by bolts, and the driving member 220 is fixedly connected to one side of the mounting base 210. Specifically, the driving member 220 is fixedly connected to one side of the mounting base 210 by bolts, and the outer ring of the slewing bearing 230 is fixedly connected to the other side of the mounting base 210. When specifically set, the outer ring of the slewing bearing 230 is fixedly connected to the other side of the mounting base 210 by bolts, and the inner ring of the slewing bearing 230 is configured to be transmission-connected to the output end of the driving member 220, and the recovery winch 240 is fixedly connected to the inner ring of the slewing bearing 230. Preferably The recovery capstan 240 is fixedly connected to the inner ring of the slewing bearing 230 by bolts. In order to facilitate the hook member 340 to be hung, a felt net is pre-arranged on the recovery capstan 240. In the process of fishing net recovery, the fishing net is relatively loose. Although the fishing net can be directly collected by the fishing net sorting component 400 for squeezing and shrinking, the fishing net is still in a fluffy state, which is not convenient for twisting into a rope and reducing the volume. It is easy to be blocked at the fishing net sorting component 400. When the fishing net is recovered, the recovery capstan 240 is rotated to drive the fishing net to be tied around the recovery capstan 240. When the fishing net is recovered, the driving member 220 is started, and the driving member 220 drives the inner ring of the slewing bearing 230 to rotate around the outer ring. The inner ring of the slewing bearing 230 drives the recovery capstan 240 to rotate. The recovery capstan 240 drives the fishing net to be continuously twisted and gathered, and the fishing net is twisted from a loose state into a dense strand rope. The main purpose of this is to facilitate the storage and cleaning of the fishing net in the capstan and to facilitate the cutting of the fishing net.

[0041] like Figure 3 As shown, the driving member 220 includes a motor 221 and a gear 222. The gear 222 is fixedly connected to the output end of the motor 221. The gear 222 is meshed with the inner ring of the slewing bearing 230. When driving the recovery capstan 240 to rotate, the motor 221 is started, and the motor 221 drives the gear 222 to rotate. Through the gear transmission principle, the gear 222 drives the inner ring of the slewing bearing 230 to rotate, thereby driving the recovery capstan 240 to rotate.

[0042] like Figure 4As shown, the tow hook assembly 300 includes a first support 310, a second support 320, a third support 330, and a tow hook member 340. The first support 310, the second support 320, and the third support 330 are all arranged on the deck of the cleaning ship body 100. The first support 310 is located at the bow, the third support 330 is located above the recovery winch assembly 200, and the second support 320 is located between the first support 310 and the third support 330. One end of the tow hook member 340 is received in the first support 310, and the end of the tow hook member 340 is hooked to the first support 310. The other end of the tow hook member 340 is hooked to the third support 330. One end of the tow hook member 340 near the third support 330 is received on the second support 320. Both ends of the tow hook member 340 can be detached from the third support 330, and both ends of the tow hook member 340 can be released and detached from the first support 310 and the second support 320. After one end of the tow hook member 340 is detached, it can be hooked into the recovery winch assembly 200. When in use, one end of the tow hook member 340 is detached from the third support 330 and falls under the action of gravity until the tow hook member 340 is hooked to the recovery winch 240. The other end of the tow hook member 340 is detached from the first support 310, and the tow hook member 340 is continuously released from the first support 310. The falling end of the tow hook member 340 falls into the water through the fishing net sorting assembly 400. After the cleaning ship body 100 sails to the designated water area, the tow hook member 340 is lowered to a depth of 1.5 m below the water surface. If the remote operator can observe the fishing net floats, the remote control boat is operated to the fishing net. If the remote operator cannot observe the fishing net floats, the boat is allowed to freely navigate in the designated water area without repeating the route for "blind sweeping" of the designated area. When there is a certain tension in the tow rope, it is considered that the tow hook contacts the fishing net. At this time, the recovery winch 240 is used to retract the fishing net for easy storage.

[0043] As Figure 5 shown, the first support 310 includes a first bracket 311, a first receiving cylinder 312, a first rope receiving frame 313, a first elastic snap ring 314, and a first hook detachment portion 315. The lower parts of both ends of the first bracket 311 are fixedly connected to both sides of the bow of the cleaning ship body 100. Among them, the first bracket 311 is fixed to the cleaning ship body 100 by welding or bolts. Two groups of first receiving cylinders 312 are provided, and each group of first receiving cylinders 312 is provided with a plurality of them. The two groups of first receiving cylinders 312 are staggered and arranged at the top inside the first bracket 311. The first receiving cylinders 312 are vertically arranged. Preferably, the top of the first receiving cylinder 312 is fixedly connected to the top inside the first bracket 311 by bolts.

[0044] As Figure 6As shown, the first rope collecting frame 313 includes a rope sorting plate 3131 and a first rope guiding ring 3132. The upper end of the rope sorting plate 3131 is fixedly connected to one side of the top end of the first receiving cylinder 312. The rope sorting plate 3131 is fixedly connected to the first receiving cylinder 312 by welding. The rope sorting plate 3131 is used to sort out the steel cables 341 tied on the first receiving cylinder 312 to reduce the looseness of the steel cables 341 on the first receiving cylinder 312. The first rope guiding ring 3132 is fixedly connected to the lower end of the rope sorting plate 3131. The first rope guiding ring 3132 and the first receiving cylinder 312 are correspondingly arranged. The steel cables 341 are gathered by the first rope guiding ring 3132, which can also reduce the spreading of the steel cables 341 and facilitate bundling.

[0045] like Figure 7 and Figure 8 As shown, the towing hook member 340 includes a steel cable 341, a fixing sleeve 342, a hook 343 and a hanging ring rope 344. The fixing sleeve 342 is fixedly connected to both ends of the steel cable 341. The hooks 343 are arranged at equal intervals on the outer wall of the fixing sleeve 342. The hanging ring rope 344 is fixedly connected to the outer wall of the upper end of the fixing sleeve 342. One end of the steel cable 341 passes through the first rope guide ring 3132. The first elastic clamp ring 314 is fixedly connected to the top of the first storage tube 312 away from the rope management plate 313. On one side, the steel cable 341 passes through the first rope guide ring 3132 and is pressed into the first elastic clamp ring 314. The steel cable 341 is wrapped around the first storage tube 312. The rope sorting plate 3131 is attached to the outer wall of the wrapped steel cable 341. One end of the wrapped steel cable 341 passes through the first rope guide ring 3132 again. The first unhooking part 315 is fixedly connected to the lower side of the first rope guide ring 3132. The hanging ring rope 344 is hung on the first unhooking part 315. The hanging ring rope 344 is set as a steel wire rope. When the towing hook 340 is in use, the head of the towing hook 340 is located at the bow. If the unhooking operation is performed manually, the risk of falling into the water is increased, and the manual operation efficiency is low. When the towing hook 340 needs to be released and the fixing sleeve 342 with the hook 343 falls into the water, the first unhooking part 315 is activated to release the hooking ring rope 344 and the first unhooking part 315. Under the action of the gravity of the fixing sleeve 342, the fixing sleeve 342 drives the steel cable 341 tied to the first storage cylinder 312 to be released. After the steel cable 341 on the first storage cylinder 312 is released, the fixing sleeve 342 is released. Under the action of gravity, the steel cable 341 is disengaged from the first elastic clamp 314 and the first rope ring 3132, so that the steel cable 341 and the first support 310 are completely separated, thereby achieving the purpose of automatic unhooking, so that the head of the towing hook member 340 on each first storage cylinder 312 can be unhooked in turn, and each towing hook member 340 can be recovered in turn to facilitate continuous operation. The storage and rope sorting plate 3131 of the first storage cylinder 312 is used to straighten and prevent loosening, so as to facilitate the storage of the head of the steel cable 341 and the unhooking operation of the head under the action of gravity.

[0046] likeFigure 9 As shown, the first decoupling part 315 includes a mounting bracket 3151, a baffle 3152 and an electromagnetic pin 3153. One end of the mounting bracket 3151 is fixedly connected to the lower side of the first cable loop 3132. Specifically, one end of the mounting bracket 3151 is fixedly connected to the lower side of the first cable loop 3132 by welding. The baffle 3152 is fixedly connected to one end of the lower side of the mounting bracket 3151. It should be noted that the baffle 3152 is fixedly connected to one end of the lower side of the mounting bracket 3151 by welding. The electromagnetic pin 3153 is fixedly connected to the other end of the lower side of the mounting bracket 3151. Preferably, the electromagnetic pin 3153 is fixedly connected to the other end of the lower side of the mounting bracket 3151 by screws. The output end of the electromagnetic pin 3153 can be inserted into the baffle 3152. The hanging loop rope 344 is hung into the output end of the electromagnetic pin 3153. When the electromagnetic pin 3153 is activated, the electromagnetic pin 3153 retracts from the baffle 3152, releasing the connection between the electromagnetic pin 3153 and the hanging loop rope 344. The fixed sleeve 342 can be quickly connected through the electromagnetic pin 3153, thereby reducing the release of the steel cable 341 after winding. Also, the fixed sleeve 342 can be quickly released, thereby quickly releasing the wound steel cable 341 for rapid decoupling operation.

[0047] As Figure 10As shown, the second support 320 includes a second bracket 321, a second storage cylinder 322, a second cable reel 323, and a second elastic snap ring 324. The lower parts of both ends of the second bracket 321 are fixedly connected to both sides of the cleaning ship body 100. Specifically, when setting, the lower parts of both ends of the second bracket 321 are fixedly connected to both sides of the cleaning ship body 100 by welding or bolts. The second storage cylinder 322 is arranged staggeredly and obliquely at the top inside the second bracket 321. The bottom end of the second storage cylinder 322 faces the recovery winch assembly 200. The second storage cylinder 322 and the first storage cylinder 312 are arranged correspondingly. The second cable reel 323 and the first cable reel 313 have the same structure. The second cable reel 323 is arranged on one side of the upper end of the second storage cylinder 322. The second elastic snap ring 324 and the first elastic snap ring 314 have the same structure. The second elastic snap ring 324 is fixedly connected to the side of the top end of the second storage cylinder 322 far from the second cable reel 323. One end of the steel cable 341 close to the third support 330 is pressed into the second elastic snap ring 324. The steel cable 341 passes through the second cable reel 323. The steel cable 341 is wound around the second storage cylinder 322. The wound steel cable 341 then passes through the second cable reel 323 again. When using the tow hook member 340, the tail of the tow hook member 340 is located at the recovery winch assembly 200. If manual unhooking operation is carried out and if there is a misoperation of the recovery winch assembly 200, it is easy to pose a safety hazard to the operator. When storing the steel cable 341, the steel cable 341 is bent near the recovery winch assembly 200 and then passes through the first cable guiding ring 3132 on the second cable reel 323. Then the steel cable 341 is wound around the second storage cylinder 322 in sequence. The cable arranging plate 3131 on the second cable reel 323 is used to prevent loosening. Then one end of the wound steel cable 341 is pressed into the second elastic snap ring 324, thereby achieving the operation of storing the tail steel cable 341. Through the second support 320 for storage, when manually winding the steel cable 341, the personnel are far away from the recovery winch assembly 200, reducing the situation that the misoperation of the recovery winch assembly 200 affects the safety of the operator.

[0048] As Figure 11As shown, the third support 330 includes a third bracket 331 and a second decoupling portion 332. The two sides of the lower end of the third bracket 331 are fixedly connected to the two sides of the cleaning ship body 100. It should be noted that the two sides of the lower end of the third bracket 331 are fixedly connected to the two sides of the cleaning ship body 100 by welding or bolts. The second decoupling portion 332 is fixedly connected to the top end inside the third bracket 331. The second decoupling portion 332 has the same structure as the first decoupling portion 315. The hanging loop rope 344 at the end of the steel cable 341 away from the first decoupling portion 315 is hooked into the output end of the electromagnetic pin 3153 on the second decoupling portion 332. A tow hook member 340 can be used to recover the fishing net in sequence, which is not convenient for continuous recovery of the fishing net. Moreover, when towing the fishing net through the tow hook member 340, if the connection between the tow hook member 340 and the recovery winch assembly 200 is not firm, the tow hook member 340 is likely to fall off the recovery winch assembly 200, thus affecting the recovery of the fishing net. When decoupling operation of the tail of the tow hook member 340 is required, the electromagnetic pin 3153 on the second decoupling portion 332 is activated to release the connection between the electromagnetic pin 3153 and the hanging loop rope 344 at the tail of the steel cable 341. Under the action of gravity, the fixing sleeve 342 at the tail of the steel cable 341 drops. After the fixing sleeve 342 is detached, it swings down with the second storage cylinder 322 as the center, so that the fixing sleeve 342 can swing to a position at the middle and rear of the recovery winch assembly 200, and then the hook on the fixing sleeve 342 can be hooked onto the felt net or the already recovered fishing net, reducing the situation where the fixing sleeve 342 drops and fails to hook into the recovery winch assembly 200. The hook 343 on the fixing sleeve 342 is hooked into the recovery winch assembly 200, and the recovery winch assembly 200 is started. The recovery winch assembly 200 drives the steel cable 341, and the steel cable 341 is pulled out from the second storage cylinder 322. The recovery winch assembly 200 pre-receives one circle in advance to achieve the purpose of tightening the tail steel cable 341, reducing the situation where the steel cable 341 drops from the recovery winch assembly 200 at the initial stage when the recovery winch 240 drives the fishing net to twist and close continuously. After the tail steel cable 341 is fixed, the head steel cable 341 is released, so that the fixing sleeve 342 with the hook 343 at the head of the steel cable 341 falls into the water for fishing net recovery operation. After one fishing net cleaning is completed, the tow hook member 340 has been wound into the recovery winch assembly 200 along with the fishing net. For the next operation, another tow hook member 340 needs to be automatically dropped. In this way, the tow hook member 340 is detached in sequence to perform continuous operation of fishing net recovery.

[0049] As Figure 12As shown, the fishing net arranging assembly 400 is arranged at the top of the bow of the cleaning boat body 100, and the other end of the towing hook 340 can pass through the fishing net arranging assembly 400 after being detached. The fishing net arranging assembly 400 includes an upper arranging frame 410, two support plates 420 and a lower arranging frame 430. The two support plates 420 are correspondingly arranged on both sides between the upper arranging frame 410 and the lower arranging frame 430. The upper arranging frame 410 and the lower arranging frame 430 are both fixedly connected to the top of the bow of the cleaning boat body 100. The recovered fishing nets are gathered by the upper arranging frame 410 and the lower arranging frame 430, so as to facilitate the recovery of the spread fishing nets.

[0050] like Figure 13 and Figure 14 The support plate 420 includes a plate body 421, and a first slide groove 422 and a second slide groove 423 are opened on the plate body 421, and the second slide groove 423 is located at the lower side of the first slide groove 422. A cutting piece 440 is arranged between the first slide grooves 422 on the two plate bodies 421, and the cutting piece 440 includes two first driving rods 441, a first connecting frame 442 and a blade 443. The two first driving rods 441 are fixedly connected to the inside of the top of the bow of the cleaning boat body 100. Preferably, the two first driving rods 441 are fixedly connected to the inside of the top of the bow of the cleaning boat body 100 by bolts, and the output end of the first driving rod 441 extends out of the cleaning boat body 100, and the first connecting frame 442 is fixedly connected to the end of the output end of the first driving rod 441. The two ends of the blade 443 are fixedly connected between the first connecting frame 442. Preferably, the two ends of the blade 443 are fixedly connected between the first connecting frame 442 by bolts, and the first driving rod 441 can drive the blade 443 to move along the first connecting frame 442. When the fishing net is recovered, it is easy to be blocked between the upper sorting frame 410 and the lower sorting frame 430 due to the large size of the fishing net or the angle of the foreign objects attached to it. If the recovery winch assembly 200 is continued to be used for recovery, it is easy to have insufficient winch retraction force or the bow of the ship entering water. When the fishing net wound on the recovery winch assembly 200 is full, but the fishing net being recovered has not been completely recovered, this part of the fishing net is not easy to detach. When the winch cannot be withdrawn, such as insufficient winch retraction force, insufficient capacity, bow entering water, etc., the first driving rod 441 is started, and the first driving rod 441 drives the first connecting frame 442 and the blade 443 to slide along the first sliding groove 422, and the blade 443 is used to cut and separate the fishing net, so that the cut fishing net continues to be recovered, and the other part of the fishing net falls back into the water for another recovery, so that the blocked or full capacity fishing net that has not been recovered falls off the fishing net cleaning boat, thereby reducing the situation where the fishing net cleaning boat drags the fishing net forward.

[0051] like Figure 15As shown, a net pressing member 450 is arranged between the second chute 423 on the two plates 421, and the net pressing member 450 includes two second driving rods 451, a second connecting frame 452 and a net pressing plate 453. The two second driving rods 451 are fixedly connected to the inside of the top of the bow of the cleaning boat body 100, the output end of the second driving rod 451 extends out of the cleaning boat body 100, the second connecting frame 452 is fixedly connected to the end of the output end of the second driving rod 451, and the two ends of the net pressing plate 453 are fixedly connected between the second connecting frames 452, and the second driving rod 451 can drive the net pressing plate 453 to slide along the second chute 423. The second driving rod 451 is set as a hydraulic oil cylinder, and the power of the hydraulic oil cylinder can be taken from the cleaning boat body 100. The end of the net pressing plate 453 is set as a triangle, so that the net pressing plate 453 can press the fishing net. The triangular top of the net pressing plate 453 is set as an arc shape to reduce the net pressing plate 453 from cutting the fishing net. During the cutting process of the fishing net, the upper end of the fishing net is pulled by the steel cable 341, but the lower part of the fishing net is not fixed. When the blade 443 cuts and separates the fishing net, it will be inconvenient to press the fishing net tightly at the top position of the bow of the cleaning boat body 100. The fishing net is easily driven by the blade 443, which may easily cause the cutting position to change, and may easily affect the cutting efficiency. When cutting the fishing net, first start the second driving rod 451, and the second driving rod 451 drives the second connecting frame 452 and the net pressing plate 453. The net pressing plate 453 presses the fishing net tightly at the top position of the bow of the cleaning boat body 100 to fix the fishing net, and then start the first driving rod 441 to cut the fishing net, so that the position of the fishing net is stable, which is convenient for the blade 443 to cut the same position, thereby improving the cutting efficiency.

[0052] like Figure 16 The upper tidying frame 410 includes a fixing plate 411, a guide grid frame 412 and a limiting rod 413. The guide grid frame 412 is fixedly connected to one side of the fixing plate 411. The fixing plate 411 is fixedly connected to the top of the bow of the cleaning boat body 100. The limiting rod 413 is fixedly connected to the inside of the guide grid frame 412. The blade 443 and the pressing plate 453 can be stored in the limiting rod 413 away from the bow of the cleaning boat body 100. The lower tidying frame 430 has the same structure as the upper tidying frame 410. When the blade 443 and the pressing plate 453 are not in use, the blade 443 and the pressing plate 453 are stored in The limiting rod 413 is away from the bow side of the cleaning boat body 100, which reduces the contact between the blade 443 and the net pressing plate 453 when the fishing net is recovered, thereby reducing the situation where the fishing net recovery pulls the blade 443 and the net pressing plate 453, causing damage to the blade 443 and the net pressing plate 453. Reinforcement frames 414 are fixedly connected to both sides of the guide net frame 412. The reinforcement frames 414 are inclined. The reinforcement frames 414 are fixedly connected to the bow of the cleaning boat body 100 at one end away from the guide net frame 412. The reinforcement frames 414 are used to improve the connection strength between the guide net frame 412 and the cleaning boat body 100.

[0053] This embodiment provides a recycling structure for a fishing net cleaning ship, including the aforementioned recycling winch assembly 200. The structure of the recycling winch assembly 200 has been disclosed previously and will not be described in detail here.

[0054] This embodiment further provides a dragging and recycling device, including a recycling structure for a fishing net cleaning ship and a tow hook assembly 300. The structures of the recycling structure for a fishing net cleaning ship and the tow hook assembly 300 have been disclosed previously and will not be described in detail here.

[0055] Specifically, the working principle of this dragging and recycling device is as follows: When recycling the fishing net, the recycling winch 240 rotates to drive the fishing net to be wound around the recycling winch 240. When the fishing net is recycled, the driving member 220 is started, and the driving member 220 drives the inner ring of the slewing bearing 230 to rotate around the outer ring. The inner ring of the slewing bearing 230 drives the recycling winch 240 to rotate, and the recycling winch 240 drives the fishing net to twist and close continuously, turning the fishing net from a loose state into a dense stranded rope. This purpose is mainly to facilitate the storage and cleaning of the fishing net in the winch and is beneficial to the cutting of the fishing net.

[0056] One end of the tow hook member 340 disengages from the third support 330 and falls under the action of gravity until the tow hook member 340 is hooked to the recycling winch 240. The other end of the tow hook member 340 disengages from the first support 310, and the tow hook member 340 is continuously released from the first support 310. The falling end of the tow hook member 340 falls out of the water. After the cleaning ship body 100 sails to the designated water area, the tow hook member 340 is lowered to a depth of 1.5 m below the water surface.

[0057] When using the tow hook member 340, the tail of the tow hook member 340 is located at the recycling winch 240. If manual unhooking operation is carried out and there is a misoperation of the recycling winch 240, it is easy to pose a safety hazard to the operator. When storing the tow hook member 340, the tow hook member 340 is stored through the second support 320. Since the second support 320 is located between the third support 330 and the first support 310, when manually winding the tow hook member 340, the personnel are far away from the recycling winch 240, reducing the impact on the safety of the operator caused by the misoperation of the recycling winch 240.

[0058] It should be noted that the specific model specifications of the motor 221, the recycling winch 240, the electromagnetic pin 3153, the first driving rod 441, and the second driving rod 451 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The power supply and principle of the electromagnetic pin 3153 are clear to those skilled in the art and will not be described in detail here.

[0060] The above are only embodiments of the present application and are not intended to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
