Description

Technical Field

[0001] The present invention relates to the technical field of marine aquaculture, and in particular to an inlet and outlet structure of a flexible fishing device. Background Art

[0002] Marine aquaculture is an important form of marine economy, and deep-sea cages are a major form of marine aquaculture. Deep-sea cages are mainly composed of cage frames, net cables, anchoring systems and supporting facilities. They utilize the interaction of fixed platforms and the cages' own characteristics to lower the cages to a limited underwater depth for fish farming.

[0003] At present, when large fully submersible deep-sea cages are used to catch fish in the cages, the entire cage needs to be floated from the seabed for centralized fishing. This fishing method will not only catch immature fish in advance and cause economic losses, but also greatly increase the difficulty and complexity of fishing operations.

[0004] Therefore, how to solve the above problems is to design an inlet and outlet structure of a fish trap that can be used for cage fishing operations, which can automatically open the fish inlet in the deep sea to catch mature fish and can also automatically open the fish outlet to release immature fish.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0009] Multiple sets of flexible bending actuators;

[0010] The free ends of two adjacent flexible bending actuators are in a butt-jointed state;

[0011] The fixed ends of two adjacent flexible bending actuators are in a butt-jointed state;

[0012] The flexible bending actuator is driven to bend on the same side, and a first gap is generated between the free ends of two adjacent flexible bending actuators, where the first gap serves as a fish inlet;

[0013] The fixed ends of the two adjacent flexible bending actuators are driven to move away from each other in opposite directions, and a second gap is generated between the fixed ends of the two adjacent flexible bending actuators, and the second gap serves as a fish outlet.

[0014] Preferably, it further includes:

[0015] An elastic member, connected between the fixed ends of two adjacent flexible bending drivers, and its tensile elastic force forces the fixed ends of the two adjacent flexible bending drivers to be in a butting state;

[0016] A linear driver, located between the fixed ends of two adjacent flexible bending drivers, and capable of driving the fixed ends of the two adjacent flexible bending drivers to move away from each other in the opposite direction.

[0017] Preferably, the flexible bending driver includes a flexible airbag, the flexible airbag is connected to a hydraulic system, and a bendable rigid sheet is bonded to its inner side.

[0018] Preferably, the flexible bending driver further includes a rigid side plate and a bushing;

[0019] The rigid side plate is fixed at the fixed end of the flexible airbag;

[0020] The bushing is fixed at the upper and lower ends of the rigid side plate;

[0021] The inlet and outlet structure of the flexible fishing device further includes two cross beams arranged vertically;

[0022] The bushings at the upper and lower ends of the rigid side plate are respectively sleeved on the cross beams arranged vertically;

[0023] Wherein, the elastic member is connected between two adjacent bushings; the linear driver is located between two adjacent rigid side plates.

[0024] Preferably, the flexible airbag is square in shape, and its inner cavity is divided into a plurality of strip-shaped cavities by a plurality of flexible partitions distributed along the width direction of the flexible airbag.

[0025] Preferably, the flexible airbag is made of silicone, and the rigid sheet is made of hard plastic.

[0026] Preferably, the linear driver is a flexible linear driver.

[0027] Preferably, the flexible linear driver includes a soft tube, and a braided sleeve that wraps the soft tube; both ends of the soft tube are fixedly connected between the fixed ends of two adjacent flexible bending drivers; the soft tube is connected to a hydraulic system; the soft tube is made of silicone.

[0028] Preferably, among them, for the bushing provided at the fixed end of the flexible bending driver, the bushing close to the fish inlet is fixedly connected to the cross beam, and the bushing far from the fish inlet slides on the cross beam.

[0030] The inlet and outlet structure of a flexible fishing device provided by an embodiment of the present invention has the following beneficial effects:

[0031] 1. The present invention designs an inlet and outlet structure of a flexible fishing device, integrating the fish inlet and the fish outlet. Multiple fish attracting and driving operations are carried out inside the fishing device, enabling the capture of fish of a certain size and the release of fish below the size.

[0032] 2. A flexible bending actuator is used as the fish inlet and outlet of the fishing device. When fish enter, it can adapt to the flexible structure of the organism itself, preventing fish from being injured during collisions. At the same time, when fish exit, it can also achieve the effect of only allowing large fish to enter and not exit.

[0033] 3. The deformation amount of the flexible bending actuator is related to the input pressure. Therefore, the input pressure can be adaptively adjusted according to the size of different fish, realizing an orderly adjustment of the deformation amount of the flexible bending actuator.

[0034] 4. The two sides of adjacent flexible bending actuators bend to form a converging area. The two bending side walls of the converging area concentrate the fish school, effectively improving the screening efficiency. When the fish body collides irregularly inside the fishing device, guiding with the wall surface can effectively concentrate the fish school to the fish outlet for screening.

[0035] 5. When the fish inlet is closed, the flexible bending actuator and the flexible linear actuator self-reset and close under the action of the internal stress of the flexible structure itself and the spring, reducing the gap, so that the fishing device reduces water loss during the rising process to ensure the water temperature and improve the activity of the fish.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

[0043] Refer to Figures 1-6 。

[0044] In view of the problems mentioned in the above background technology, the embodiments of the present invention provide a flexible fishing device inlet and outlet structure to solve the above technical problems. The technical solutions are as follows:

[0045] A flexible fishing device inlet and outlet structure includes:

[0046] Multiple groups of flexible bending drivers; in this embodiment, four groups of flexible bending drivers are provided;

[0047] The free ends a of two adjacent flexible bending drivers are in a butting state;

[0048] The fixed ends b of two adjacent flexible bending drivers are in a butting state;

[0049] When driving the flexible bending drivers to bend on the same side, a first gap will be generated between the free ends a of two adjacent flexible bending drivers, and the first gap is the fish inlet;

[0050] When driving the fixed ends b of two adjacent flexible bending drivers to move away from each other in the opposite direction, a second gap will be generated between the fixed ends b of two adjacent flexible bending drivers, and the second gap is the fish outlet.

[0051] Among them, the "free end, fixed end" of the flexible bending driver specifically refers to: when driving the flexible bending driver to perform a bending operation, the end that bends along with the flexible bending driver is the free end, and the end that does not bend together with the flexible bending driver is the fixed end.

[0052] The operation method of fishing and driving fish for the flexible fishing device inlet and outlet structure provided by the embodiments of the present invention is as follows:

[0053] 1. Figure 5 、 Figure 6 As shown in; drive the flexible bending drivers to bend on the same side, the free ends a of the two adjacent flexible bending drivers in the middle position are opened, and an inner V-shaped fish inlet is formed. Bait can be placed in the fishing device to lure the fish school to enter the fishing device from the fish inlet in the direction shown by arrow B;

[0054] 2. Drive the fixed ends b of two adjacent flexible bending drivers to move away from each other in the reverse direction. The fixed ends b of the two adjacent flexible bending drivers open to form a fish outlet, and sound waves can be generated inside the fishing device to drive the fish school to escape from the fishing device through the fish outlet in the direction shown by arrow C;

[0055] 3. By controlling the distance between the fish inlet and the fish outlet and performing multiple fish attracting and driving operations inside the fishing device, the purpose of catching fish of a certain size and releasing fish below the size can be achieved.

[0056] It should be noted here that if the fish inlet and the fish outlet are opened simultaneously, it is necessary to ensure that the size of the fish outlet is smaller than that of the fish inlet to prevent the fish school inside the fishing device from escaping.

[0057] In this embodiment, the inlet and outlet structure of the flexible fishing device further includes: an elastic member 400 and a linear driver 300;

[0058] The elastic member 400 is connected between the fixed ends b of two adjacent flexible bending drivers, and its tensile elastic force forces the fixed ends b of the two adjacent flexible bending drivers to be in a butted state; preventing the caught fish from escaping through the gap between the fixed ends b of the two adjacent flexible bending drivers;

[0059] The linear driver 300 is located between the fixed ends b of two adjacent flexible bending drivers and can drive the fixed ends b of the two adjacent flexible bending drivers to move away from each other in the reverse direction; the linear driver 300 serves as the power source for the fixed ends b of the two adjacent flexible bending drivers to move away from each other in the reverse direction.

[0060] In this embodiment, the flexible bending driver includes a flexible airbag 240. The flexible airbag 240 is connected to a hydraulic system, and a bendable rigid sheet is bonded to its inner side; a whole rigid sheet covers the inner side of the flexible airbag 240; among them, the azimuth term "inner side" is relative to the fishing device. The inside of the fishing device is the inner side, and the outside of the fishing device is the outer side.

[0061] When the hydraulic system inputs high pressure into the internal cavity of the flexible airbag 240, since the outer side of the flexible airbag 240 is made of flexible material, the wall surface will elongate. However, on the inner side of the flexible airbag 240, there is a bendable rigid sheet with a relatively large elastic modulus, and the rigid sheet will limit the elongation of this wall surface. Finally, under the combined action of the length changes on both sides, the flexible airbag 240 bends, and the bending angle is related to the pressure.

[0062] When the fishing work is completed, at this time, the linear driver 300 stops working. The fish inlet slowly drains water and closes under the action of the internal stress of the flexible airbag 240, and the fish outlet closes under the action of the elastic member 400. Finally, it reaches the closed state as shown in Figure 1 shown.

[0063] It should be noted here that since the outer side of the flexible bending driver is made of flexible material with low stiffness, when the fish inlet is opened and fish enter the fishing device, fish bodies larger than the inlet size can also smoothly enter under the guiding action of the side wall surface of the flexible bending driver; since a rigid sheet with a large elastic modulus and bendability is bonded to the inner side of the flexible bending driver and has a large stiffness, when the fish outlet is opened and fish escape from the fishing device, the fish in the fishing device gather in the rigid fish outlet under the guiding action of the side wall, and only fish smaller than the outlet size can smoothly escape.

[0064] In this embodiment, the flexible bending driver further includes a rigid side plate 210 and a bushing 220;

[0065] The rigid side plate 210 is fixed at the fixed end b of the flexible airbag 240; the material of the rigid side plate 210 can be a hard plastic plate, an alloy plate, etc.;

[0066] The bushing 220 is fixed at the upper and lower ends of the rigid side plate 210;

[0067] The inlet and outlet structure of the flexible fishing device further includes two cross beams 100 arranged up and down; the cross beams 100 not only serve as the overall framework of the inlet and outlet structure of the flexible fishing device, but also play a guiding role in the movement of the fixed end b of the flexible airbag 240;

[0068] The bushings 220 at the upper and lower ends of the rigid side plate 210 are respectively sleeved on the cross beams 100 arranged up and down;

[0069] Among them, the elastic member 400 is connected between two adjacent bushings 220; the tensile elastic force of the elastic member 400 forces the fixed ends b of two adjacent flexible bending drivers to be butt - joint sealed through the two rigid side plates 210;

[0070] The linear driver 300 is located between two adjacent rigid side plates 210; when the fixed ends b of two adjacent flexible bending drivers need to be moved away, the linear driver 300 directly pushes the two rigid side plates 210 to move the fixed ends b of two adjacent flexible bending drivers away from each other in the reverse direction.

[0071] Figure 3 As shown; in this embodiment, the flexible airbag 240 is square in shape, and its inner cavity is divided into a plurality of strip - shaped cavities 241 by a plurality of flexible partitions distributed along the width direction of the flexible airbag 240; the material of the flexible partitions is the same as that of the flexible airbag 240.

[0072] By arranging a plurality of flexible partitions distributed along the width direction of the flexible airbag 240 in the inner cavity of the flexible airbag 240, when high - pressure is input into the strip - shaped cavities 241, the flexible partitions play a role of a skeleton, which can promote the flexible airbag 240 to be stretched by stamping along the width direction and prevent the flexible airbag 240 from stretching disorderly after stamping.

[0073] In this embodiment, the material of the flexible airbag 240 is silicone, and the rigid sheet is hard plastic; the hard plastic is preferably an ABS plastic sheet, which is bonded to the inner side of the flexible airbag 240 through a special silicone glue.

[0074] In this embodiment, the linear actuator 300 is a flexible linear actuator.

[0075] In this embodiment, the flexible linear actuator 300 includes a soft tube and a braided sleeve that wraps around the soft tube; both ends of the soft tube are fixedly connected between the fixed ends b of two adjacent flexible bending actuators; the soft tube is connected to a hydraulic system; the material of the soft tube is silicone.

[0076] When the hydraulic system is controlled to pressurize the cavity of the soft tube, the external braided sleeve will restrict the growth of the radial dimension, and finally cause the overall structure to stretch axially, and the elongation length is related to the pressure;

[0077] It should be noted that the braided sleeve is a radial restraint structure, and this radial restraint structure determines the elongation direction of the soft tube; the structural form of the radial restraint structure is diverse, and other structures such as fiber restraint structure, corrugated structure, folding / pleating structure, etc. can also be used to achieve it.

[0078] In this embodiment, for the bushing 220 provided on the fixed end b of the flexible bending actuator, the bushing 220 near the fish inlet is fixedly connected to the cross beam 100 by screws, and the bushing 220 far from the fish inlet slides on the cross beam 100;

[0079] When the linear actuator 300 extends, the fixed end b of the flexible bending actuator on the side near the fish inlet does not move, and the fixed end b of the flexible bending actuator on the side far from the fish inlet moves to complete the opening action of the fish outlet.

[0080] In this embodiment, the inlet and outlet structure of the flexible fishing device is installed on the fishing device; the fishing device adopts a common fishing device, such as an airtight box or a net cage, etc.; when a small net cage is used, the cross beam 100 of the inlet and outlet structure of the flexible fishing device is installed on the frame of the small net cage, and the free end a of the flexible bending actuator at the side position of the inlet and outlet structure of the flexible fishing device is connected to the fishing net of the small net cage.

They may be located in one place or distributed to multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment.
