Detailed implementation manners

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

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] Next, a fishing net cleaning boat according to an embodiment of the present application will be described with reference to the drawings.

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

[0040] As shown Figure 2 in the figure, the recovery winch assembly 200 is fixedly connected to the cleaning ship body 100 near the middle position. 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. Among them, the mounting base 210 is fixedly connected to the cleaning ship body 100 near the middle position by bolts. 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. The outer ring of the slewing bearing 230 is fixedly connected to the other side of the mounting base 210. When specifically arranged, the outer ring of the slewing bearing 230 is fixedly connected to the other side of the mounting base 210 by bolts. The inner ring of the slewing bearing 230 is configured to be drivingly connected to the output end of the driving member 220. The recovery winch 240 is fixedly connected to the inner ring of the slewing bearing 230. Preferably, the recovery winch 240 is fixedly connected to the inner ring of the slewing bearing 230 by bolts. For the convenience of hooking the hook member 340, a felt net is pre-set on the recovery winch 240. During the process of recovering the fishing net, the fishing net is relatively loose. When directly collecting the fishing net, although the fishing net can be squeezed and contracted by the fishing net sorting assembly 400, the fishing net is still in a fluffy state, which is not convenient for twisting into a rope and reducing the volume, and is easy to block at the fishing net sorting assembly 400. When recovering the fishing net, the recovery winch 240 rotates to drive the fishing net to wind around the recovery winch 240. When recovering the fishing net, the driving member 220 is started. 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 winch 240 to rotate. The recovery winch 240 drives the fishing net to continuously twist and gather, twisting the fishing net from a loose state into a dense strand 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.

[0041] As shown Figure 3 in the figure, 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 meshes with the inner ring of the slewing bearing 230. When driving the recovery winch 240 to rotate, the motor 221 is started. 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, and then drives the recovery winch 240 to rotate.

[0042] As shown 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, 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, and one end of the tow hook member 340 close to the third support 330 is received on the second support 320. Both ends of the tow hook member 340 can be disengaged from the third support 330, and both ends of the tow hook member 340 can be released and disengaged from the first support 310 and the second support 320. After one end of the tow hook member 340 is disengaged, it can be hooked into the recovery winch assembly 200. During use, one end of the tow hook member 340 is disengaged 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 disengaged 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 to perform a "blind sweep" 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 storage cylinder 312, a first rope winding frame 313, a first elastic snap ring 314, and a first hook release 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 storage cylinders 312 are provided, and each group of first storage cylinders 312 is provided with a plurality of them. The two groups of first storage cylinders 312 are staggered and arranged at the top inside the first bracket 311. The first storage cylinders 312 are vertically arranged. Preferably, the top of the first storage 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 rope loop 3132. Specifically, one end of the mounting bracket 3151 is fixedly connected to the lower side of the first rope 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, 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 staggeredly and obliquely arranged 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. 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. After being wound, the steel cable 341 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 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, so as to complete 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. Both sides of the lower end of the third bracket 331 are fixedly connected to both sides of the cleaning ship body 100. It should be noted that both sides of the lower end of the third bracket 331 are fixedly connected to both sides of the cleaning ship body 100 by welding or bolts. The second decoupling portion 332 is fixedly connected to the top 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 towing hook member 340 can perform the recovery operation of the fishing net in sequence, which is not convenient for continuously performing the recovery operation of the fishing net. Moreover, when towing the fishing net through the towing hook member 340, if the connection between the towing hook member 340 and the recovery winch assembly 200 is not firm, the towing hook member 340 is likely to fall off from the recovery winch assembly 200, thereby affecting the recovery of the fishing net. When it is necessary to perform the decoupling operation at the tail of the towing hook member 340, 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 rear of the middle part on 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 be hooked 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 detached from the second storage cylinder 322. The recovery winch assembly 200 pre-receives one circle to achieve the purpose of tightening the tail steel cable 341. By pre-receiving the steel cable 341 through the recovery winch assembly 200 when recovering the fishing net, the fixing force of the tail steel cable 341 is improved, and further, the situation where the steel cable 341 falls off from the recovery winch assembly 200 at the initial stage when the recovery winch 240 drives the fishing net to continuously twist and converge is reduced. 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 to perform the recovery operation of the fishing net. After completing the cleaning of one fishing net, the towing hook member 340 has been involved in the recovery winch assembly 200 along with the fishing net. To perform the next operation, another towing hook member 340 needs to be automatically released. In this way, the towing hook member 340 is detached in sequence to perform the continuous operation of recovering the fishing net.

[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. 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 towing hook device for a fishing net cleaning ship, including the aforementioned towing hook assembly 300. The structure of the towing hook assembly 300 has been disclosed previously and will not be described in detail here.

[0054] This embodiment further provides a towing hook system for a fishing net cleaning ship, including the aforementioned towing hook device for a fishing net cleaning ship and a recovery winch assembly 200. The structure of the recovery winch assembly 200 has been disclosed previously and will not be described in detail here.

[0055] Specifically, the working principle of the towing hook device and system for a fishing net cleaning ship is as follows: When it is necessary to release the towing hook member 340 so that the fixed sleeve 342 with the hook 343 falls into the water, the first hook release part 315 is activated to release the connection between the hanging ring rope 344 and the first hook release part 315. Under the action of the gravity of the fixed sleeve 342, the fixed sleeve 342 drives the steel cable 341 wound around the first storage cylinder 312 to be released. After the steel cable 341 on the first storage cylinder 312 is completely released, under the action of gravity, the steel cable 341 disengages from the first elastic snap ring 314 and the first lead rope ring 3132, and then the steel cable 341 is completely separated from the first support 310, thus achieving the purpose of automatic hook release, facilitating the sequential hook release operation of the heads of the towing hook members 340 on each first storage cylinder 312. Each towing hook member 340 can recover a fishing net in sequence, facilitating continuous operation. Through the storage of the first storage cylinder 312 and the rope arranging plate 3131 for straightening and preventing loosening, it is convenient to store the head of the steel cable 341 and also facilitate the head hook release operation under the action of gravity.

[0056] When it is necessary to perform the decoupling operation on the tail of the towing hook member 340, 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, and 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 the position at the rear of the upper middle part of the recovery winch assembly 200, so that the hook on the fixing sleeve 342 can be hooked on the felt net or the already recovered fishing net, reducing the situation where the fixing sleeve 342 drops and fails to be hooked 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 activated. The recovery winch assembly 200 drives the steel cable 341, and the steel cable 341 is disengaged from the second storage cylinder 322. The recovery winch assembly 200 pre-recovers one circle to achieve the purpose of tightening the tail steel cable 341. When recovering the fishing net, by pre-storing the steel cable 341 through the recovery winch assembly 200, the fixing force of the tail steel cable 341 is improved, and further, the situation where the steel cable 341 falls off the recovery winch assembly 200 at the initial stage when the recovery winch 240 drives the fishing net to continuously twist and close is reduced. 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 to perform the fishing net recovery operation. After completing one fishing net cleaning, the towing hook member 340 has been wound into the recovery winch assembly 200 along with the fishing net. For the next operation, another towing hook member 340 needs to be automatically put in. In this way, the towing hook member 340 is successively detached to perform continuous operations for fishing net recovery.

[0057] It should be noted that the specific model specifications of the motor 221, the recovery 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. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0058] The power supply and principle of the electromagnetic pin 3153 are clear to those skilled in the art and will not be elaborated here.
