Embodiment 1

[0028] Such as Figure 1-5 Shown, a kind of high-efficiency trapping system of double catch system for purse seine culture in large area waters, including pile 2, catch device 9, classification area 20, trapping area 21, bait throwing area 22, catch platform 24, pile 2 A guide rail 28 is laid on the top of the guide rail 28, and a catch mechanism 29 is installed above the guide rail 28. The left side of the guide rail 28 is provided with a catch platform 24, and the both sides of the catch platform 24 are provided with a trapping area 21, and a trapping device is placed inside the trapping area 21. 9. The device is fully functional, with purse seine breeding and trapping functions. The guide rail laid on the pile can make the fishing machine move back and forth to expand the fishing range. The fishing device is placed in the trapping area and can quickly catch fish. Increase the catching efficiency, the catching platform uses a rigid frame structure, which can better maintain...

Embodiment 2

[0034] Such as Figure 1-9 Shown, net bag 5 edge places are provided with several airbags 11, and airbag 11 inside is provided with counterweight 12, is connected with trachea 13 on each airbag 11, and the upper end of trachea 13 is connected with net bag 5 around. The weight of the net bag will become heavier when it sinks in the water, and the weight of the counterweight in the airbag will make the net bag sink faster and improve fishing efficiency. The net bag has better stability at the bottom and will not be broken up by waves , After finishing fishing, ventilate the air bag to make the air bag in an inflated state, and the net bag will have a small amount of buoyancy. its service life.

[0035] Offer buoyancy hole 17 on the net of net bag 5, and buoyancy hole 17 is ellipse, and both sides in buoyancy hole 17 are provided with corresponding elastic bent plate 16, and the elastic bent plate 16 middle part horizontal of both sides is also connected with an elastic bent pla...

Embodiment 3

[0039] In the actual use of the high-efficiency trapping system of a double-capturing system for purse seine culture in large-area waters of the present invention, the cultivator fixes the pile 2, and can operate according to the needs of cultivating and trapping, and put the fry into the culture For farming in the area, when it is necessary to collect the net, first put the submersible net 1 and the catch device 9 into the bottom of the water, and after the multiple intelligent baiting systems feed the bait to attract a large number of fish, quickly lift the surrounding submerged net 1 to the water surface, and put the fish shoal Trapped below the platform. At the same time, it starts to be lifted slowly by the cantilever of the catching mechanism, and the two coordinate and merge to operate, and the catching frame device slowly sinks, and gradually opens the blocking mesh plate 8, so that fish schools enter the catching device 9, and the frame device sinks to the bottom of th...

Abstract

The invention provides a double-catching system efficient trapping system for large-area water area purse net breeding, and belongs to the technical field of facility breeding engineering. The double-catching system efficient trapping system comprises piles, catching devices, a grading region, trapping regions, bait throwing regions and a catching platform. Guide rails are laid on the upper portions of the piles, a catching machine installed on the upper portions of the guide rails, the catching platform is arranged on the left sides of the guide rails, the trapping regions are arranged on thetwo sides of the catching platform, and the catching devices are arranged inside the trapping regions. The double-catching system efficient trapping system has the functions of breeding, catching andtrapping, can realize artificial intelligence and mechanization, sieve fishes and keep the shape of a net well, and can automatically clear off attachments on the net through impacting of seawater.

Description

technical field [0001] The invention belongs to the field of facility breeding engineering equipment, and in particular relates to a high-efficiency trapping system of a double-capturing system for seine breeding in large-area waters. Background technique [0002] At present, the seine aquaculture project urgently needs to focus on the development of fast and efficient fishing methods and devices in the case of seine aquaculture in large-area waters, so that it has high safety performance, is suitable for large-area seine aquaculture in shallow seas, and can greatly save costs cost. [0003] Shallow sea seine culture has a large area, no nets at the bottom, and the culture environment is closer to the natural ecology, but the feeding and catching methods of farmed fish are different from traditional cage culture, near-shore seine culture and marine fishing, so it is necessary to Carry out the research and development of special trapping facilities for deep-water seine farmi...
