Description

Technical Field

[0001] The invention relates to the technical field of fishery trawl nets, and in particular to a water layer regulating device for Antarctic krill fishing operations. Background Art

[0002] A beam is a commonly used fishing trawl equipment, which is used to tow the fishing net when fishing in the ocean. The existing beam trawl used for Antarctic krill fishing carries the trawl through the beam, and the beam is connected to the traction system of the fishing boat through the traction line. The fishing boat sails and tows the beam trawl to sweep the sea for fishing. Traditional beam trawls are mainly used to catch marine life such as fish, shrimps, crabs and shellfish living in the near-sea layer, and the operating water depth is generally less than 20m. Since there are a large number of young fish and shrimps living in the offshore waters, the catches caught by traditional beam trawls are small in size and low in economic value, but the damage to fishery resources is greater. During the operation process, the height of the net mouth is limited by the towing speed. If the towing speed is too high, the traditional beam trawl will leave the seabed, and if the towing speed is too low, the beam will touch the seabed and the net mouth will be difficult to open. In both cases, it is difficult to capture the catch, and the trawl needs to be at a suitable water layer height for capture.

[0003] In order to solve the problem of lifting and diving adjustment of spar trawl, the prior art provides a variety of solutions. For example, the prior art CN114987726B discloses an adjustable driving device for trawling fishing boats. The device makes the gap between the propeller blade tip and the second duct adjustable by translating the driving assembly, increases the duct gap under high-speed conditions, and then reduces the interaction between the duct and the propeller, so that the performance of the ducted propeller under high-speed conditions is close to that of the non-ducted propeller. The device solves the problem that most of the traditional propeller ducts in the prior art are fixedly installed, the distance and aspect ratio between the duct and the propeller blade tip are fixed, and it is not possible to take into account the problem of working with better propulsion efficiency under two different conditions of low speed and normal navigation. Another example is the prior art NO347258B1, which discloses a capture processing system including a capture collection system. The capture collection system includes a capture processing section; one or more trawls; and a capture transportation system, wherein the capture transportation system includes a transportation system, and wherein the transportation system includes a transportation node. The transport node includes a releasable connection with a fish processing group carrying drone and with one or more units of the fish processing group, but the above-mentioned prior arts still have room for improvement in how to enhance the lifting and diving adjustment function of the boom in the boom trawling operation. Summary of the invention

[0004] The purpose of the present invention is to provide a water layer regulating device for Antarctic krill fishing operations, which can actively control the rise and fall of the device in the water so that the device can operate in a target water layer, and the device has high stability during operation in the water.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: a water layer regulating device for Antarctic krill fishing operation, including a driving member, a truss assembly is connected to the side of the driving member through a base frame, the driving member includes a shell of a rotating body structure, the two ends of the shell are through-set, the shell has a built-in substrate parallel to its axis, a generator is provided on the substrate, and one end of the shell is provided with a blade connected to the generator. The present invention collects energy from the water flow during the towing process by arranging a generator and a blade, and outputs the energy after storing the energy to control the up and down movement of the truss assembly, so as to achieve the rise and fall of the regulating device as a whole in the water to reach a suitable water layer height for the capture operation. In this way, there is no need to set up additional energy or connect the ship to the device, the probability of device operation failure is reduced, and the stability of the device in the water operation is improved.

[0006] According to one embodiment of the present invention, the blade is connected to the generator through a first rotating shaft, a coaxial second gear is provided on the first rotating shaft, a first gear coaxial with the generator input shaft is provided on one side of the generator, and the first gear is meshed with the second gear.

[0007] When the trawl moves in the water, the contact between the water and the paddle blades drives the paddle blades to rotate, thereby driving the first shaft to rotate. The rotation of the first shaft drives the second gear to rotate, and the second gear drives the first gear to rotate, thereby making the generator work.

[0008] According to one embodiment of the present invention, a third gear is provided at the output end of the generator, a sixth gear meshing with the third gear is built into the shell, the sixth gear is coaxially connected to the second worm, the second worm is rotatably connected to the shell, a second turbine is provided on one side of the second worm, a fifth gear is coaxially connected to the side of the second turbine, the fifth gear is provided with a fourth gear, the fourth gear is coaxially connected to the first transmission rod, the fourth gear and the fifth gear are both rotatably connected to the mounting plate, and the mounting plate is connected to the shell. When the truss assembly needs to be adjusted, the power output at the output end of the generator drives the third gear to rotate, the third gear drives the sixth gear to rotate, and then the second worm can drive the second turbine to produce rotational motion, and the rotation of the second turbine can drive the fifth gear and the fourth gear on its side to produce rotational motion, and then output power to the first transmission rod, and the first transmission rod further outputs power to the truss assembly for lifting and diving adjustment. In this case, the fifth gear is arranged on both sides of the second turbine, so that power can be output in two directions synchronously, so that the truss assembly can be arranged on both sides of the driving member to expand the adjustment range of the device during the trawling process, and when the truss assembly needs to be adjusted, the present invention adopts a multi-set gear transmission method to output power from the generator, thereby solving the problem of excessive power output causing the truss assembly posture to change too quickly in a short period of time, causing the truss assembly to deform.

[0009] According to one embodiment of the present invention, a deflector is provided on the outer side of the blade, the deflector is connected to the housing, a baffle is provided on the outer side of the first rotating shaft, and the baffle is connected to the inner wall of the deflector through a seal. The deflector is used to guide the fluid to be discharged after contacting the blade, and the baffle and the seal are provided to prevent water from entering the interior of the driving member.

[0010] According to one embodiment of the present invention, the sealing member includes a circular sealing ring, a second groove is provided on the surface of the sealing ring, the second groove passes through the sealing ring, a first groove is arranged around the surface of the sealing ring and is coaxially arranged therewith, and a third concave groove is arranged around the side of the sealing ring. The setting of the sealing ring can fill the gap between the guide cover and the baffle to prevent external water from entering the interior of the driving member. The second groove is provided on the sealing ring so that the sealing ring can enhance the filling tightness of the sealing ring in the process of filling the gap between the guide cover and the baffle. The deformation of the sealing ring caused by extrusion during the filling process is released at the second groove, and the sealing ring is squeezed at the second groove. The second groove is sealed by pressure, thus solving the problem of sealing failure after the sealing ring is deformed due to filling or long-term use. The first groove and the third groove are further arranged on the sealing ring to alleviate the deformation of the sealing ring. At the same time, the vibration of the guide cover and the baffle can be transmitted to the sealing ring. The sealing ring absorbs the vibration of the above-mentioned guide cover and the baffle by releasing the deformation to each groove and then recovering the deformation. The sealing ring is arranged in the gap between the guide cover and the baffle. The second groove on the sealing ring has a certain guiding flow direction for the water flowing through, specifically, the water flows along the direction of the second groove, thus helping the water to be quickly discharged from the guide cover.

[0011] According to one embodiment of the present invention, the truss assembly has a truss plate, and the truss plate has a rotating rod body that passes through both ends of the truss plate, and the two ends of the truss plate are connected to a second connecting plate through the rotating rod body. The truss plate provided by the present invention can rotate relative to the second connecting plate, and specifically the rotating rod body and the second connecting plate are rotatably connected, so that the direction of the force acting on the truss plate and the water flow when the truss plate moves in the water can be achieved by controlling the rotation of the truss plate relative to the second connecting plate, so as to control the rise or fall of the entire device in the water. The above scheme simplifies the existing complex adjustment equipment, and the lifting and diving adjustment can be achieved by controlling the truss plate relative to the second connecting plate. While 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 one embodiment of the present invention, the side of the second connecting plate has a fourth plate body, the fourth plate body has an arc-shaped slide groove, and both ends of the truss plate have sliders slidably connected to the arc-shaped slide groove. The rotation range of the truss plate is controlled by setting the fourth plate body to cooperate with the slider on the side of the truss plate, so as to solve the problem that the rotation range of the truss plate in the 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 slide groove and the slider can passively limit the rotation range of the truss plate. It should be emphasized that the cooperation of the arc-shaped slide groove and the slider relatively strengthens the connection relationship between the side of the truss plate and the second connecting plate, and the probability of shaking or deformation of the truss plate during the movement of the truss plate in the water can be reduced. Specifically, the force on the truss plate can be partially transmitted to the second connecting plate through the contact of objects or the force can be consumed by the sliding of the truss plate relative to the arc-shaped slide groove.

[0013] According to one embodiment of the present invention, the second connecting plates are connected by at least two second rods, and the second rods are connected by the first rod, and the axis of the first rod has an angle with the axis of the second rod. A plurality of second rods are used to connect and fix the adjacent second connecting plates, so that a storage space can be formed between the two second connecting plates, and the second rod and the first rod are provided to further limit the storage space, so that the truss plate can be prevented from moving out of the formed storage space, and vice versa, the second rod and the truss plate inside the first rod are protected to prevent the truss plate from being damaged by the impact of objects on the sea surface or in the water, especially the damage to the truss plate caused by the continuous collision of some fish during sea fishing. The second rod and the first rod are helpful to generate noise around the truss plate by interacting with the water flow to drive away the organisms around the truss plate, and reduce the probability of damage caused by the collision of the organisms. In addition, the second rod and the first rod enhance the overall structural strength of the device and help ensure the stable state of the device working in water.

[0014] According to one embodiment of the present invention, the truss is equipped with an adjustment component, which includes an assembly box with an accommodating space, the assembly box has a built-in first rotatable turbine, a side of the first turbine is connected to a lead screw coaxial with the turbine, a through hole is provided on the surface of the truss, and connecting substrates are provided in the upper and lower directions of the through hole respectively, the connecting substrate is hinged to the truss on one side of the through hole through a connecting block, and a first through groove is provided on the connecting substrate, and the lead screw can move relative to the first through groove. Under the action of the first turbine, the lead screw is driven to rotate, which can then drive the truss plate to swing up and down, thereby realizing the rise and fall adjustment of the entire device in the water. The scheme of hinged connection between the connecting block and the truss plate can solve the problem of excessive stress on the truss plate causing the truss plate to be broken or damaged when subjected to external force. Specifically, when the truss plate is in contact with the water during the movement of the truss plate in the water, the truss plate is continuously subjected to the impact force of the water relative to the water body. When an upward lifting force or downward pressure is suddenly applied to the truss plate, the truss plate is prone to deformation or damage in the area subjected to the upward lifting force or downward pressure. The connecting block and the truss plate of the present invention are hinged, and the upward lifting force or downward pressure can be first applied to the connecting base plate, and then transmitted to the truss plate, thus solving the problem of regional deformation or damage of the truss plate when it is lifted up and down.

[0015] According to one embodiment of the present invention, a worm gear is provided on one side of the assembly box and is equipped with a first turbine. The worm gear is connected to a first transmission rod coaxial with the worm gear, and the first transmission rod can perform rotational motion. The first transmission rod can be connected to the worm gear through a coupling, thereby causing the worm gear to perform rotational motion and drive the first turbine to rotate.

[0016] According to one embodiment of the present invention, an auxiliary plate group is provided on the bottom surface of the truss plate, the auxiliary plate group has an auxiliary horizontal plate arranged parallel to the truss plate and with a spacing, the auxiliary horizontal plate has a nut equipped with a lead screw, vertical plates are provided at both ends of the auxiliary horizontal plate, a connecting shaft is provided on the side of the vertical plate, a rotating connecting rod connected thereto is provided on the connecting shaft, and the rotating connecting rod is connected to the connecting base plate. The auxiliary plate group is connected to the lead screw, and the rotation of the lead screw can drive the up and down displacement of the auxiliary plate group, and then can drive the up and down displacement of the connecting base plate, so as to achieve the adjustment of the rise and fall of the device as a whole in the water, and solve the problem that the truss plate is broken or damaged due to excessive stress when subjected to external force.

[0017] The side of the assembly box is connected to the third connecting plate, and the third connecting plate is provided with a connecting and mounting hole for assembling with the second rod body. The third connecting plate is arranged with the second rod body, and the surface of the third connecting plate is arranged perpendicular to the axis of the second rod body. The second rod body is used to limit the assembly box to ensure that the assembly box does not move, and the position of the lead screw remains unchanged, while the nut matched with the lead screw drives the auxiliary plate group to move.

[0018] The third connecting plate has a groove at one end relative to the truss plate, and there is an air space between the third connecting plate and the truss plate, so as to avoid the problem that the two collide or get stuck when the truss plate swings due to the third connecting plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the present invention collects energy from the water flow during the towing process by setting a generator and a paddle, and outputs the stored energy to control the up and down movement of the truss assembly, thereby adjusting the rise and fall of the entire device in the water to reach a suitable water layer height for capture operations. Under the action of the first turbine, the lead screw is driven to rotate, which can then drive the truss plate to swing up and down, thereby adjusting the rise and fall of the entire device in the water, wherein the solution of hinged connection between the connecting block and the truss plate can solve the problem of excessive stress on the truss plate when subjected to external force, resulting in the truss plate being broken or damaged.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0025] Embodiment 1 like Figure 1-Figure 10 As shown, the water layer regulating device for Antarctic krill fishing operation includes a driving member 10, and the driving member 10 is connected to a truss assembly 40 on the side through a base frame 50. The driving member 10 includes a housing 11 of a rotating body structure, and the two ends of the housing 11 are through-set. The housing 11 has a base plate 12 parallel to its axis built in it, and a generator 13 is provided on the base plate 12. One end of the housing 11 is provided with a blade 15 connected to the generator 13. The present invention collects energy from the water flow during the towing process by arranging the generator 13 and the blade 15, and outputs the energy after storing the energy to control the up and down movement of the truss assembly 40, so as to realize the rise and fall of the regulating device as a whole in the water to reach a suitable water layer height for the capture operation. In this way, there is no need to set up additional energy or connect the ship to the device, the probability of device operation failure is reduced, and the stability of the device in the water operation is improved.

[0026] The blade 15 is connected to the generator 13 via a first rotating shaft 16 . A coaxial second gear 17 is provided on the first rotating shaft 16 . A first gear 14 coaxial with the input shaft of the generator 13 is provided on one side of the generator 13 . The first gear 14 meshes with the second gear 17 .

[0027] When the trawl moves in the water, the water contacts the paddle 15, causing the paddle 15 to rotate, thereby driving the first shaft 16 to rotate. The first shaft 16 rotates, driving the second gear 17 to rotate, and the second gear 17 drives the first gear 14 to rotate, thereby causing the generator 13 to work.

[0028] A third gear 18 is provided at the output end of the generator 13, and a sixth gear 112 meshing with the third gear 18 is built into the housing 11. The sixth gear 112 is coaxially connected to a second worm, and the second worm is rotatably connected to the housing 11. A second turbine 110 is provided on one side of the second worm, and a fifth gear 111 is coaxially connected to the side of the second turbine 110. The fifth gear 111 is provided with a fourth gear 19, and the fourth gear 19 is coaxially connected to the first transmission rod 20. The fourth gear 19 and the fifth gear 111 are both rotatably connected to a mounting plate 113, and the mounting plate 113 is connected to the housing 11. When the strutting assembly 40 needs to be adjusted, the power output at the output end of the generator 13 drives the third gear 18 to rotate, and the third gear 18 drives the sixth gear 112 to rotate, so that the second worm can drive the second turbine 110 to generate a rotational motion, and the rotation of the second turbine 110 can drive the fifth gear 11 and the fourth gear 19 on its side to generate a rotational motion, and then output the power to the first transmission rod 20, and the first transmission rod 20 further outputs the power to the strutting assembly 40 for lifting and diving adjustment. In this case, the fifth gear 111 is arranged on both sides of the second turbine 110, so that power can be output in two directions synchronously, so that the strutting assembly 40 can be arranged on both sides of the driving member 10 to expand the adjustment range of the equipment during the trawling process, and when the strutting assembly 40 needs to be adjusted, the present invention adopts a multi-set gear transmission method to output power from the generator 13, thereby solving the problem that the posture of the strutting assembly 40 changes too quickly in a short time due to excessive power output, resulting in deformation of the strutting assembly 40.

[0029] A deflector 114 is provided outside the blade 15, and the deflector 114 is connected to the housing 11. A baffle 15 is provided outside the first rotating shaft 16, and the baffle 15 is connected to the inner wall of the deflector 114 through a seal 60. The deflector 114 is used to guide the fluid to be discharged after contacting the blade 15, and the baffle 15 and the seal 60 are provided to prevent water from entering the interior of the driving member 10.

[0030] The sealing member 60 includes an annular sealing ring 61, and a second groove 63 is provided on the surface of the sealing ring 61. The second groove 63 runs through the sealing ring 61. A first groove 62 is arranged coaxially therewith on the surface of the sealing ring 61, and a third concave groove 64 is arranged on the side of the sealing ring 61. The setting of the sealing ring 61 can fill the gap between the deflector 114 and the baffle 15 to prevent external water from entering the interior of the driving member 10. The second groove 63 is provided on the sealing ring 61 so that the sealing ring 61 can fill the gap between the deflector 114 and the baffle 15. The filling tightness of the sealing ring 61 is enhanced in the process of filling the gap between the deflector 114 and the baffle 15. The deformation of the sealing ring 61 caused by extrusion during the filling process is released at the second groove 63, and the sealing ring 61 is squeezed at the second groove 63. The second groove 63 is sealed, thereby solving the problem of sealing failure after the sealing ring 61 is deformed due to filling or long-term use. The first groove 62 and the third groove 64 are further provided on the sealing ring 61 to alleviate the deformation of the sealing ring 61. At the same time, the vibration of the air deflector 114 and the baffle 15 can be transmitted to the sealing ring 61. The sealing ring 61 absorbs the vibration of the air deflector 114 and the baffle 15 by releasing the deformation to each groove and then recovering the deformation. The sealing ring 61 is set in the gap between the air deflector 114 and the baffle 15. The second groove 63 on the sealing ring 61 has a certain guiding effect on the flow direction of the water flowing through, specifically, the water flows along the direction of the second groove 63, which helps the water to be quickly discharged from the air deflector 114.

[0031] The truss assembly 40 has a truss plate, and the truss plate has a rotating rod body 41 that passes through both ends of the truss plate, and the two ends of the truss plate are connected to the second connecting plate 52 through the rotating rod body 41. The truss plate provided in the present invention can rotate relative to the second connecting plate 52, and specifically, the rotating rod body 41 and the second connecting plate 52 are rotatably connected, so that the direction of the force acting on the truss plate and the water flow when the truss plate moves in the water can be realized by controlling the rotation of the truss plate relative to the second connecting plate 52, so as to control the rise or fall of the entire device in the water. The above scheme simplifies the existing complex adjustment equipment, and the lifting and diving adjustment can be realized by controlling the truss plate relative to the second connecting plate 52. Under the condition 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.

[0032] The side of the second connecting plate 52 has a fourth plate body 521, the fourth plate body 521 has an arc-shaped slide groove, and the two ends of the truss plate have sliders slidably connected to the arc-shaped slide groove. The rotation range of the truss plate is controlled by setting the fourth plate body 521 to cooperate with the slider on the side of the truss plate, so as to solve the problem that the rotation range of the truss plate in the 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 slide groove and the slider can passively limit the rotation range of the truss plate. It should be emphasized that the cooperation of the arc-shaped slide groove and the slider relatively strengthens the connection relationship between the side of the truss plate and the second connecting plate 52, and the probability of shaking or deformation of the truss plate during the movement of the truss plate in the water can be reduced. Specifically, the force on the truss plate can be partially transmitted to the second connecting plate 52 through the contact of objects or the force is consumed by the sliding of the truss plate relative to the arc-shaped slide groove.

[0033] The second connecting plates 52 are connected by at least two second rods 55, and the second rods 55 are connected by the first rod 53, and the axis of the first rod 53 and the axis of the second rod 55 have an angle. The adjacent second connecting plates 52 are connected and fixed by multiple second rods 55, so that a storage space can be formed between the two second connecting plates 52, and the second rod 55 and the first rod 53 are provided to further limit the storage space, so that the truss plate can be prevented from moving out of the formed storage space, and vice versa, the second rod 55 and the truss plate inside the first rod 53 are protected to prevent the truss plate from being damaged by the impact of objects on the sea surface or in the water body, especially the damage to the truss plate caused by the continuous collision of some fish during the sea fishing process. The second rod 55 and the first rod 53 are helpful to generate noise around the truss plate with the water flow to drive away the organisms around the truss plate, and reduce the probability of biological collision and damage. In addition, the second rod 55 and the first rod 53 enhance the overall structural strength of the device and help ensure the stable state of the device working in water.

[0034] The truss is equipped with an adjustment component 30, which includes an assembly box 31 with a accommodating space. The assembly box 31 has a built-in first turbine 32 that can rotate. A lead screw 36 coaxial with the first turbine 32 is connected to the side of the first turbine 32. A through hole is opened on the surface of the truss, and connecting base plates 34 are respectively provided in the upper and lower directions of the through hole. The connecting base plate 34 is hinged to the truss on one side of the through hole through a connecting block 37. A first through groove is provided on the connecting base plate 34, and the lead screw 36 can move relative to the first through groove. Under the action of the first turbine 32, the lead screw 36 is driven to rotate, which can then drive the truss plate to swing up and down, thereby realizing the rise and fall adjustment of the entire device in the water. The scheme of hinged connection between the connecting block 37 and the truss plate can solve the problem of excessive stress on the truss plate causing the truss plate to be broken or damaged when subjected to external force. Specifically, when the truss plate is in contact with the water during the movement of the truss plate in the water body, the truss plate is continuously subjected to the impact force of the water body relative to the water body. When an upward lifting force or downward pressure is suddenly applied to the truss plate, the truss plate is prone to deformation or damage in the area subjected to the upward lifting force or downward pressure. The connecting block 37 of the present invention is hinged to the truss plate, which can first apply the upward lifting force or downward pressure to the connecting base plate 34, and then transmit it to the truss plate, thus solving the problem of regional deformation or damage of the truss plate when it is lifted up and down.

[0035] A worm 33 is provided on one side of the assembly box 31 and is equipped with the first turbine 32. The worm 33 is connected to a first transmission rod 20 coaxial with the worm 33, and the first transmission rod 20 can make a rotational motion. Under the action of the power mechanism, the first transmission rod 20 is driven to make a rotational motion. The first transmission rod 20 can be connected to the worm 33 through a coupling, so that the worm 33 makes a rotational motion and drives the first turbine 32 to rotate.

[0036] An auxiliary plate group 35 is provided on the bottom surface of the truss plate. The auxiliary plate group 35 has an auxiliary horizontal plate arranged parallel to the truss plate and with a spacing therebetween. The auxiliary horizontal plate has a nut equipped with a lead screw 36. Vertical plates are provided at both ends of the auxiliary horizontal plate. A connecting shaft is provided on the side of the vertical plate. A rotating connecting rod connected thereto is provided on the connecting shaft. The rotating connecting rod is connected to the connecting base plate 34. The auxiliary plate group 35 is connected to the lead screw 36. The rotation of the lead screw 36 can drive the auxiliary plate group 35 to move up and down, and then drive the connecting base plate 34 to move up and down, thereby realizing the adjustment of the rise and fall of the device as a whole in the water, and solving the problem that the truss plate 42 is broken or damaged due to excessive stress when the truss plate is subjected to external force.

[0037] The side of the assembly box 31 is connected to the third connecting plate 54, and the third connecting plate 54 is provided with a connecting and mounting hole for assembling with the second rod 55. The third connecting plate 54 and the second rod 55 are arranged, and the surface of the third connecting plate 54 is perpendicular to the axis of the second rod 55. The second rod 55 limits the assembly box 31 to ensure that the assembly box 31 does not move, and the position of the lead screw 36 remains unchanged, while the nut matched with the lead screw 36 drives the auxiliary plate group 35 to move.

[0038] The third connecting plate 54 has a slot at one end opposite to the truss plate, and there is an empty space between the third connecting plate 54 and the truss plate to prevent the truss plate 42 from colliding or getting stuck when the third connecting plate 54 causes the truss plate 42 to swing.

[0039] Embodiment 2: This embodiment provides the following scheme based on the side-mounted Antarctic krill truss trawling water layer regulating truss equipment of embodiment 1, see attached Figure 1 , Attachment Figure 3 As shown, there are two truss assemblies 40, which are arranged opposite to each other, with a driving member 10 provided therebetween. The outer side of the driving member 10 is connected to a first connecting plate 51 which can be fixedly assembled with a 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 the two are fixedly connected by fasteners.

[0040] The base frame 50 is a cylindrical structure. The interior of the base frame 50 is hollow and connected to the interior of the driving member 10, and the internal hollow structure of the base frame 50 passes through the first connecting plate 51. In this way, batteries, electrical components, etc. can be arranged inside the base frame 50 to be electrically connected to the driving member 10, and various sensor monitoring and data transmission can be performed, etc., providing installation space for the equipment.

[0041] It should be noted that sealing structures such as sealing rings are provided at the connection between the hollow part of the base frame 50 and the first connecting plate 51 and the driving member 10 to prevent water from entering the device. In this way, a sealed space can be formed inside to provide relative buoyancy for the driving member 10, etc., to prevent the driving member 10 and the base frame 50 from being in the water. Due to the driving member 10 and the base frame 50 in the middle of the device being too heavy and the truss assemblies 40 on both sides being too light, the driving member 10 and the base frame 50 move downward relatively, and the device in the water does not form a good horizontal expansion shape. This ensures that the device moves smoothly in the water and prevents the truss assemblies 40 on both sides of the driving member 10 from deforming.
