[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0035] The fishing net recovery system according to the embodiments of the present application will be described below with reference to the drawings.

[0036] Please refer to Figures 1 to 14 The fishing net recovery system according to the embodiments of the present application comprises a winding type fishing net arrangement mechanism 300 and a fishing net recovery mechanism 400.

[0037] Please refer to Figures 1 to 2 The winding type fishing net arrangement mechanism 300 is arranged at the front end of the cleaning ship, and the fishing net recovery mechanism 400 is arranged on the winding type fishing net arrangement mechanism 300. The fishing net recovery mechanism 400 comprises a return sliding rail 410, a return supporting member 420, a return motor member 430, a return rack 440, a swing frame member 450, a swing movement oil cylinder 460, a rigid fishing net recovery member 470 and a recovery driving member 480. The return sliding rail 410 is fixedly connected to the two sides of the upper end of the winding type fishing net arrangement mechanism 300. The return supporting member 420 is slidably connected to the return sliding rail 410. The return motor member 430 is installed in the return supporting member 420. The return rack 440 is fixedly connected to the upper end of the winding type fishing net arrangement mechanism 300. The return rack 440 and the return sliding rail 410 are arranged in parallel. The return motor member 430 cooperates with the return rack 440 to drive the return supporting member 420 to move along the return sliding rail 410. One end of the swing frame member 450 is hingedly connected to the front end of the return supporting member 420. One end of the swing movement oil cylinder 460 is hingedly connected to the return supporting member 420. The other end of the swing movement oil cylinder 460 is hingedly connected to the swing frame member 450. The swing movement oil cylinder 460 drives the swing movement oil cylinder 460 to swing around the front end of the return supporting member 420. The rigid fishing net recovery member 470 is slidably penetrated in the swing frame member 450. The recovery driving member 480 can drive the rigid fishing net recovery member 470 to slide along the swing frame member 450.

[0038] When the fishing net recovery mechanism 400 is cleaning the fishing net, the back-moving motor 430 is started, and the back-moving motor 430 drives the back-moving support 420 to slide forward along the back-moving slide rail 410 by engaging with the back-moving rack 440. When the back-moving support 420 slides to the front end, the swing movement oil cylinder 460 is started, and the swing movement oil cylinder 460 drives the swing frame 450 to flip and stand up around the front end of the back-moving support 420. The rigid fishing net recovery 470 stands up with the swing frame 450. The recovery drive 480 is started, and the recovery drive 480 drives the rigid fishing net recovery 470 to slide down along the swing frame 450 and extend into the water. The fishing net to be cleaned is hung by the rigid fishing net recovery 470. Then, the recovery drive 480 drives the rigid fishing net recovery 470 to retract. The swing movement oil cylinder 460 falls down, and the swing movement oil cylinder 460 drives the swing frame 450 to swing down and flatten. The rigid fishing net recovery 470 flattens with the swing frame 450. After that, the back-moving motor 430 drives the back-moving support 420 to slide backward along the back-moving slide rail 410. The fishing net on the rigid fishing net recovery 470 is placed on the main fishing net storage cylinder 350. The rigid fishing net recovery 470 unloads the fishing net. The fishing net falls completely on the main fishing net storage cylinder 350 and is arranged and stored with the main fishing net storage cylinder 350. The fishing net recovery 470 moves up and down to adjust the cleaning depth. The rigid fishing net recovery 470 sweeps the area.

The back-moving drive gear 432 is fixedly sleeved on the output end of the back-moving motor 431 and is engaged with the back-moving rack 440. The back-moving motor 431 drives the back-moving drive gear 432. Through the engagement of the back-moving drive gear 432 and the back-moving rack 440, the back-moving drive gear 432 drives the back-moving motor 431. The back-moving motor 431 drives the main support frame 421 to slide forward and backward along the back-moving slide rail 410.

[0041] Please refer to Figures 1 to 5The rigid fishing net recovery part 470 includes a recovery moving frame 471, a passive chain 472, a chain adjusting part 473 and a retractable fishing net hook part 475. The recovery moving frame 471 slides through the swing frame part 450. The rear side of the recovery moving frame 471 is provided with an inner sink groove from top to bottom. The chain adjusting part 473 is arranged at the top of the inner sink groove. The upper end of the passive chain 472 is connected to the chain adjusting part 473. The lower end of the passive chain 472 is connected to the lower end of the inner sink groove. The swing frame part 450 can drive the recovery moving frame 471 to move along the swing frame part 450 through the passive chain 472. The retractable fishing net hook part 475 is arranged at the lower end of the recovery moving frame 471. The front and rear sides of the lower end of the retractable fishing net hook part 475 can swing out of the recovery moving frame 471 to hook the fishing net.
