Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fishing trawl net, in particular to a water layer adjusting device for Antarctic krill fishing operation. BACKGROUND

[0002] The trawl is a commonly used fishing trawl equipment, which is used to pull the trawl net to move during marine fishing. The existing trawl net for Antarctic krill fishing is carried by the trawl, and the trawl is connected to the trawl system of the fishing boat through a trawl cable, and the trawl net is pulled by the trawl through the sailing of the fishing boat to carry out sea sweeping fishing. The traditional trawl net is mainly used for fishing marine organisms such as fish, shrimp and crab and shellfish living in the near-bottom layer, and the working water depth is generally less than 20m. Because there are a large number of juvenile fish and juvenile shrimps living in the near-sea area, the size of the catch captured by the traditional trawl net is small, and the economic value is low, but the damage to the fishery resources is large. During the operation, the net opening height is limited by the trawl speed. If the trawl speed is too high, the traditional trawl net will move away from the seabed, and if the trawl speed is too low, the trawl will touch the seabed, and the net opening will be difficult to open. In the above two cases, it is difficult to capture the catch, and the trawl net needs to be in the appropriate water layer height for the fishing work.

[0003] In order to solve the problem of trawl net depth adjustment, the existing technology provides a variety of solutions, for example, the existing technology CN114987726B discloses an adjustable driving device for trawl fishing boat, which adjusts the gap between the propeller blade tip and the second guide pipe by translating the driving assembly, increases the guide pipe gap under high speed conditions, and reduces the interaction between the guide pipe and the propeller, so that the performance of the guide pipe propeller under high speed conditions is close to that of the guide pipe propeller. The performance of the guide pipe propeller under high speed conditions is close to that of the guide pipe propeller. The device solves the problem that the traditional propeller guide pipe in the prior art is mostly fixedly installed, and the distance and length-diameter ratio of the guide pipe and the propeller blade tip are fixed, which cannot work with better propulsion efficiency under low speed and normal navigation conditions. For example, the existing technology NO347258B1 discloses a catch processing system including a catch collection system. The catch collection system includes a catch processing section, one or more trawl nets, and a catch transport system, wherein the catch transport system includes a transport system, and wherein the transport system includes a transport node. The transport node includes a transport node that carries a drone with a catch processing machine group and a releasable connection with one or more units of the catch processing machine group, but the above-mentioned prior art still has room for improvement in how to improve the trawl net operation in the trawl net operation. SUMMARY

[0004] The purpose of the present application is to provide a water layer adjusting device for Antarctic krill fishing operation, which can actively control the depth of the device in water, so that the device can work in the target water layer, and the stability of the device in water during operation is high.

[0005] To solve the above technical problems, the present application specifically provides the following technical solutions: the Antarctic krill fishing operation water layer adjusting device, comprising a driving member, the driving member is connected with a girder assembly through a base frame on the side, the driving member comprises a shell with a rotary body structure, both ends of the shell are provided through, a base plate parallel to the axis of the shell is built-in, a generator is arranged on the base plate, and a paddle is arranged at one end of the shell and connected with the generator. The present application collects energy from the water flow during the towing process by setting the generator and the paddle, stores the energy, and then outputs the power to control the up-down action of the girder assembly, so as to realize the lifting and sinking of the whole adjusting device in the water to reach the appropriate water layer height for the fishing operation. In this way, it is not necessary to additionally set the energy or connect the device to the ship, the failure probability of the device is reduced, and the stability of the device in the water is improved.

[0006] According to an embodiment of the present application, the paddle is connected with the generator through a first rotating shaft, a second gear coaxial with the first rotating shaft is arranged on the first rotating shaft, a first gear coaxial with the input shaft of the generator is arranged on one side of the generator, and the first gear is engaged with the second gear.

[0007] During the movement of the trawl in the water, the water body contacts the paddle to drive the paddle to produce rotary motion, thereby driving the first rotating shaft to produce rotary motion, and the rotary motion of the first rotating shaft drives the second gear to rotate, and the second gear drives the first gear to rotate, thereby enabling the generator to work.

[0008] According to an embodiment of the present application, the generator output end is provided with a third gear, the shell is built-in with a sixth gear engaged with the third gear, the sixth gear is coaxially connected with a second worm, the second worm is rotatably connected with the shell, a second turbine is arranged on one side of the second worm, a fifth gear is coaxially connected with the second turbine on the side, a fourth gear is arranged on the fifth gear, the fourth gear is coaxially connected with a first transmission rod, the fourth gear and the fifth gear are rotatably connected on a mounting plate body, and the mounting plate body is connected with the shell. When the girder assembly needs to be adjusted, the power output end of the generator drives the third gear to rotate, the third gear drives the sixth gear to rotate, thereby the second worm can drive the second turbine to produce rotary motion, the rotary motion of the second turbine can drive the fifth gear and the fourth gear on the side to produce rotary motion, thereby the power is output to the first transmission rod, and the first transmission rod further outputs the power to the girder assembly for lifting and sinking adjustment. In the case, the fifth gear is arranged on both sides of the second turbine, so that the power can be output to two directions at the same time. In this way, the girder assembly can be arranged on both sides of the driving member to expand the adjustment range of the equipment during the towing of the trawl, and when the girder assembly needs to be adjusted, the present application adopts the mode of multiple gear transmissions to output the power from the generator. In this way, the problem of deformation of the girder assembly caused by the too fast change of the posture of the girder assembly is solved.

[0009] According to an embodiment of the present application, the paddle outer side is provided with a fairing, the fairing is connected with the shell, the first rotating shaft outer side is provided with a baffle, and the baffle is connected with the fairing inner wall through a sealing element. The fairing is arranged to guide the fluid to be discharged after contacting the paddle, and the baffle and the sealing element are arranged to avoid the water entering the inside of the driving element.

[0010] According to an embodiment of the present application, the sealing element comprises a circular ring-shaped sealing ring, the sealing ring surface is provided with a second slot, the second slot penetrates through the sealing ring, the sealing ring surface is arranged around a first slot coaxially arranged with the sealing ring, and the sealing ring side surface is arranged around a third slot concave. The sealing ring is arranged to fill the gap between the fairing and the baffle to block the external water from entering the inside of the driving element. The second slot is arranged on the sealing ring to enhance the tightness of the sealing ring during the filling of the gap between the fairing and the baffle. The deformation of the sealing ring caused by extrusion during the filling process is released at the second slot. The extrusion of the sealing ring at the second slot seals the second slot. Thus, the problem of sealing failure caused by the deformation of the sealing ring due to filling or long-term use is solved. Further, the first slot and the third slot are arranged on the sealing ring to relieve the deformation of the sealing ring. At the same time, the vibration of the fairing and the baffle can be transmitted to the sealing ring. The sealing ring absorbs the vibration of the fairing and the baffle by deforming and releasing to the slots and then recovering the deformation. The sealing ring is arranged at the gap between the fairing and the baffle. The second slot on the sealing ring has a certain flow direction guiding effect on the water flowing through. Specifically, the water flows along the direction of the second slot. Thus, it is helpful for the water to be quickly discharged from the fairing.

[0011] According to an embodiment of the present application, the beam assembly has a beam plate, the beam plate has a rotating rod body penetrating through both ends of the beam plate, and the both ends of the beam plate are connected with a second connecting plate through the rotating rod body. The beam plate can be rotated relative to the second connecting plate by the arrangement of the beam plate. Specifically, the rotating rod body is rotationally connected with the second connecting plate. Thus, the action force direction of the beam plate when moving in the water can be realized by controlling the rotation of the beam plate relative to the second connecting plate. Thus, the rising or falling of the entire device in the water is controlled. The above scheme simplifies the existing complex adjustment equipment. The rising and diving adjustment can be realized by controlling the beam plate relative to the second connecting plate. In the case of reducing the complexity of the equipment, the probability of failure in the water is reduced, which is conducive to the stable operation of the equipment in the water.

[0012] According to an embodiment of the present application, the second connecting plate side has a fourth plate body, the fourth plate body has an arc-shaped sliding groove, and the truss plate two ends have sliding blocks connected with the arc-shaped sliding groove. The fourth plate body and the sliding blocks on the truss plate side are matched to realize the rotation range control of the truss plate, so as to solve the problem that the rotation amplitude of the truss plate in water is uncontrollable or difficult to adjust. In addition, in the case of excessive water flow impact or failure of the equipment driving the truss plate to rotate, the arc-shaped sliding groove and the sliding block can passively limit the rotation range of the truss plate. It is emphasized that the cooperation of the arc-shaped sliding groove and the sliding block relatively enhances the connection relationship between the truss plate side and the second connecting plate. The shaking or deformation probability of the truss plate during the movement of the truss plate in water can be reduced. Specifically, the force on the truss plate can be partially transmitted to the second connecting plate through object contact or consumed through the sliding of the truss plate relative to the arc-shaped sliding groove.

Thus, the accommodation space can be formed between the two second connecting plates, and the accommodation space is further limited by the second rod body and the first rod body. Thus, the truss plate can be prevented from moving out of the formed accommodation space, and vice versa. The truss plate inside the second rod body and the first rod body is protected, so as to avoid the damage of the truss plate caused by the impact of objects in the sea or water body. In particular, the damage of the truss plate caused by the continuous impact of some fish during the sea catching process is avoided. The provided second rod body and first rod body help to generate noise around the truss plate by the action of water flow, so as to drive away the organisms around the truss plate and reduce the probability of damage caused by the organisms. In addition, the provided second rod body and first rod body enhance the overall structural strength of the device and help to ensure the stable state of the device working in water.

The lead screw is driven to rotate by the first turbine, and then the girder can be driven to swing up and down, so that the overall device in the water is adjusted to submerge. The hinged connection of the connecting block and the girder can solve the problem that the girder is broken or damaged due to excessive stress when the girder is subjected to external force. Specifically, when the girder is in contact with the water body during movement in the water body, the girder is continuously impacted by the water body, and suddenly upward lifting force or downward pressure is applied to the girder, the girder is prone to deformation or damage in the area subjected to the upward lifting force or the downward pressure. The connecting block and the girder are hinged, the upward lifting force or the downward pressure is first applied to the connecting base plate, and then transmitted to the girder, so that the problem of regional deformation or damage of the girder when subjected to upward and downward lifting is solved.

[0015] According to an embodiment of the present application, a worm is arranged on one side of the assembly box and matched with the first turbine, the worm is connected with a first transmission rod coaxial with the worm, and the first transmission rod can make rotary motion; the first transmission rod is driven to make rotary motion under the action of the power mechanism, the first transmission rod is connected with the worm through a shaft coupling, and then the worm makes rotary motion to drive the first turbine to rotate.

The second rod body limits the displacement of the assembly box, ensures that the position of the lead screw is unchanged, and the nut matched with the lead screw drives the auxiliary plate group to move.

[0018] The third connecting plate has a slot at one end relative to the beam plate, and has a hollow space between the third connecting plate and the beam plate, so as to avoid collision or jamming of the third connecting plate and the beam plate when the beam plate swings.

[0019] Compared with the prior art, the present application has the following beneficial effects: the generator and the paddle are arranged to collect water flow energy during towing to obtain energy, and the energy is stored and then output to control the up-down movement of the beam assembly, so that the overall adjustment device is adjusted to sink in water to reach a suitable water layer height for capture operation.

The extrusion of the sealing ring 61 at the second slot 63 seals the second slot 63. This solves the problem of sealing failure caused by deformation of the sealing ring 61 during filling or long-term use. Further, the first slot 62 and the third slot 64 on the sealing ring 61 can relieve the deformation of the sealing ring 61.

The rising and diving adjustment can be realized by controlling the truss plate relative to the second connecting plate 52. In the case of reducing the complexity of the equipment, the probability of failure in water is reduced, which is conducive to the stable operation of the equipment in water.

The fourth plate body 521 cooperates with the sliding blocks on the side of the truss plate to control the rotation range of the truss plate, so as to solve the problem that the rotation range of the truss plate in water is uncontrollable or difficult to adjust. In addition, in the case of excessive water flow impact or failure of the equipment driving the truss plate to rotate, the arc-shaped sliding groove and the sliding block can passively limit the rotation range of the truss plate. It is emphasized that the cooperation of the arc-shaped sliding groove and the sliding block enhances the connection between the side of the truss plate and the second connecting plate 52.

[0048] The third connecting plate 54 has a slot at one end relative to the truss, and there is a gap between the third connecting plate 54 and the truss to prevent the truss 42 from colliding or getting stuck when the third connecting plate 54 swings.

[0049] Example 2:

[0050] This embodiment, based on the side-mounted Antarctic krill truss trawl water layer regulating truss equipment of Embodiment 1, provides the following scheme, see appendix. Figure 1 Appendix Figure 3 As shown, there are two truss assemblies 40, which are arranged opposite to each other. A driving member 10 is provided between them. The outer side of the driving member 10 is connected to a first connecting plate 51 that can be fixedly assembled with the second connecting plate 52 through a base frame 50. The first connecting plate 51 and the second connecting plate 52 are arranged in parallel and are fixedly connected by fasteners.

[0051] The base frame 50 is a cylindrical structure with a hollow interior that communicates with the interior of the drive component 10. The hollow interior of the base frame 50 also passes through the first connecting plate 51. This allows for the placement of batteries, electrical components, etc., within the base frame 50 for electrical connection with the drive component 10, as well as for various sensor monitoring and data transmission, thus providing installation space for the equipment.

[0052] It should be noted that the hollow part of the base frame 50 is equipped with sealing rings and other sealing structures at the connection points with the first connecting plate 51 and the drive component 10 to prevent water from entering the equipment. This also creates a sealed space inside to provide relative buoyancy for the drive component 10 and the like, preventing the drive component 10 and the base frame 50 from being submerged in water. Because the drive component 10 and the base frame 50 in the middle of the device are too heavy and the truss assemblies 40 on both sides are too light, the drive component 10 and the base frame 50 move relatively downwards. The device in the water does not form a good horizontal unfolding shape. This ensures that the device moves smoothly in the water and prevents the truss assemblies 40 on both sides of the drive component 10 from deforming.
