Description

Technical Field

[0001] The invention relates to the technical field of fishery trawls, and in particular to a side-type Antarctic krill truss trawl operation water layer regulating truss equipment. Background Art

[0002] A spar is a commonly used fishing trawl equipment, used to tow the fishing net when fishing in the ocean. The existing spar trawl used for Antarctic krill fishing uses a spar to carry the trawl, and the spar is connected to the traction system of the fishing boat through a traction line. The fishing boat sails and tows the spar trawl to sweep the sea for fishing. The existing spar trawl can only passively control the depth of the water level layer by controlling the length of the traction line and the sailing speed of the fishing boat, and cannot achieve active rise and fall regulation function.

[0003] In order to solve the problem of truss lifting and diving adjustment, the prior art provides a variety of solutions. For example, the prior art CN114766442B discloses a power truss for rapid depth adjustment of Antarctic krill trawl based on intelligent control. The device includes a truss body, a connecting rod body is provided on the side of the truss body, and adjustment rods are provided at both ends of the truss body. One end of each adjustment rod is fixedly connected to the connecting rod body. The upper and lower sides of the truss body are provided with connecting assemblies, and each connecting assembly includes a plurality of connecting pieces. An adjustment mechanism is provided on the side of the truss body, and the adjustment mechanism includes a mounting shell, an adjustment assembly, a driving assembly, and a power generation assembly. The compact design of the adjustment mechanism of the device is more convenient for disassembly and maintenance, reduces costs, and the equipment is not easily damaged after the structure is simplified. Another example is the prior art DK179265B1, which discloses a trawl door for trawling fishing, which has an upper frame, a lower frame and an intermediate frame, and the upper frame, the lower frame and the intermediate frame define an intermediate frame located between the upper frame and the lower frame, thereby forming an upper part. Panels of the wing structure are provided, which are stacked on top of each other and connected to a frame at their respective ends. There are no movable and remotely controllable baffles installed below any panel. GB2161351 describes a net panel / trawl door, which includes a mounting frame, which may include an upper longitudinally extending end member formed by a plate and a lower longitudinally extending end member formed by a box-shaped keel portion. The device can solve the problem of requiring a higher angle of attack at a slower towing speed to obtain a sufficiently large drag induced force vector required to stabilize the trawl door at a slower towing speed. However, the above-mentioned prior arts all have room for improvement in how to improve the lifting and diving adjustment function of the truss in the truss trawling operation. Summary of the invention

[0004] The purpose of the present invention is to provide a side-mounted Antarctic krill truss trawling water layer regulating truss equipment to solve the technical problem that the self-adjusting depth truss equipment in the prior art is too complicated and can ensure the adjustment stability of the equipment in the water.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions: a side-mounted Antarctic krill truss trawling water layer adjustment truss equipment, including a truss assembly, the truss assembly has a truss plate, the truss plate is a plate structure, the truss plate has a rotating rod body running through both ends of the truss plate, and the two ends of the truss plate are connected with a second connecting plate through the rotating rod body. The truss plate set by the present invention can rotate relative to the second connecting plate, 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 with the water flow when moving 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 rise and fall 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.

[0006] 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.

[0007] 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.

[0008] According to one embodiment of the present invention, the truss is equipped with an adjustment component, which includes an assembly box with a accommodating space, a turbine that can rotate is built in the assembly box, a lead screw coaxial with the turbine is connected to the side of the turbine, a through hole is provided on the surface of the truss, and a connecting substrate is provided in the upper and lower directions of the through hole, the connecting substrate is hinged to the truss on one side of the through hole through a connecting block, a first through groove is provided on the connecting substrate, the lead screw can move relative to the first through groove, and the lead screw is driven to rotate under the action of the turbine, and then the truss can be driven to swing up and down, so as to realize the rise and fall adjustment of the device as a whole in the water, wherein the connecting block and the truss are connected to the truss. The plate hinge solution can solve the problem of excessive stress on the truss plate when it is subjected to external force, causing the truss plate to break or be damaged. Specifically, when the truss plate moves in the water, the truss plate is in contact with the water and is continuously subjected to the impact force of the water relative to the water. 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.

[0009] According to one embodiment of the present invention, a worm gear is provided on one side of the assembly box and is provided with a turbine. The worm gear is connected to a first transmission rod coaxial with the worm gear. The first transmission rod can perform a rotary motion. Under the action of the power mechanism, the first transmission rod is driven to perform a rotary motion. The first transmission rod can be connected to the worm gear through a coupling, so that the worm gear performs a rotary motion and drives the turbine to rotate.

[0010] 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.

[0011] According to an embodiment of the present invention, the side of the assembly box is connected to the third connecting plate, the third connecting plate is provided with a connecting and mounting hole for assembly 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, the position of the lead screw remains unchanged, and the nut matched with the lead screw drives the auxiliary plate group to move.

[0012] According to one embodiment of the present invention, the third connecting plate has a groove at one end relative to the truss plate, and there is an empty space between the third connecting plate and the truss plate to prevent the third connecting plate from causing the truss plate to swing and cause the two to collide or get stuck.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the present invention enables the truss plate to rotate relative to the second connecting plate through the arrangement, and the direction of the force acting on the truss plate against the water flow when the truss plate moves in the water is achieved by controlling the rotation of the truss plate relative to the second connecting plate, thereby controlling the rise or fall of the entire device in the water. The above scheme simplifies the existing complex adjustment equipment, and the rise and fall 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.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0018] 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.

[0019] Embodiment 1 like Figure 1-Figure 8 As shown, a side-mounted Antarctic krill truss trawling water layer regulating truss equipment includes a truss assembly 40, the truss assembly 40 has a truss plate 42, the truss plate 42 is a plate structure, the truss plate 42 has a rotating rod body 41 penetrating both ends of the truss plate 42, and both ends of the truss plate 42 are connected with a second connecting plate 52 through the rotating rod body 41. The truss plate 42 provided by the present invention can rotate relative to the second connecting plate 52, 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 42 with the water flow when moving in the water can be achieved by controlling the rotation of the truss plate 42 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 regulating equipment, and the rise and fall regulation can be achieved by controlling the truss plate 42 relative to the second connecting plate 52. 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.

[0020] The second connecting plate 52 has a fourth plate body 521 on the side thereof, and the fourth plate body 521 has an arc-shaped slide groove, and sliders are provided at both ends of the truss plate 42 to be slidably connected to the arc-shaped slide groove. The fourth plate body 521 is provided to cooperate with the slider on the side of the truss plate 42 to realize the control of the rotation range of the truss plate 42, so as to solve the problem that the rotation range of the truss plate 42 in the water is uncontrollable or difficult to adjust. In addition, in the case of excessive water flow impact or failure of the device driving the truss plate 42 to rotate, the arc-shaped slide groove and the slider can passively limit the rotation range of the truss plate 42. 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 42 and the second connecting plate 52, and the probability of shaking or deformation of the truss plate 42 during the movement of the truss plate 42 in the water can be reduced. Specifically, the force on the truss plate 42 can be partially transmitted to the second connecting plate 52 through the contact of objects or the force can be consumed by the sliding of the truss plate 42 relative to the arc-shaped slide groove.

[0021] 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 42 can be prevented from moving out of the formed storage space, and vice versa, the second rod 55 and the truss plate 42 inside the first rod 53 are protected to prevent the truss plate 42 from being damaged by the impact of objects on the sea surface or in the water body, especially the damage to the truss plate 42 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 42 with the water flow to drive away the organisms around the truss plate 42, and reduce the probability of damage caused by the collision of the organisms. 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.

[0022] The truss plate 42 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 turbine 32 that can rotate. The side of the turbine 32 is connected to a lead screw 36 coaxial with it. A through hole is provided on the surface of the truss plate 42. A connecting base plate 34 is provided in the upper and lower directions of the through hole. The connecting base plate 34 is hinged to the truss plate 42 on one side of the through hole through a connecting block 37. The connecting base plate 34 is provided with a first through groove. The lead screw 36 can move relative to the first through groove. Under the action of the turbine 32, the lead screw 36 is driven to rotate, and then the truss plate 42 can be driven to swing up and down, so as to achieve the rise and fall adjustment of the device as a whole in the water, wherein the connecting block 37 and the truss The hinged connection of the plate 42 can solve the problem that the truss plate 42 is broken or damaged due to excessive stress when it is subjected to external force. Specifically, when the truss plate 42 moves in the water, the truss plate 42 is in contact with the water and is continuously subjected to the impact force of the water relative to the water. When an upward lifting force or downward pressure is suddenly applied to the truss plate 42, the truss plate 42 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 42, so that the upward lifting force or downward pressure can be first applied to the connecting base plate 34 and then transmitted to the truss plate 42. This solves the problem of regional deformation or damage of the truss plate 42 when it is lifted up and down.

[0023] A worm 33 is provided on one side of the assembly box 31 and is provided with the turbine 32. The worm 33 is connected to a first transmission rod 20 coaxial therewith. The first transmission rod 20 can make a rotary motion. Under the action of the power mechanism, the first transmission rod 20 is driven to make a rotary motion. The first transmission rod 20 can be connected to the worm 33 through a coupling, so that the worm 33 makes a rotary motion and drives the turbine 32 to rotate.

[0024] An auxiliary plate group 35 is provided on the bottom surface of the truss plate 42. The auxiliary plate group 35 has an auxiliary horizontal plate arranged parallel to the truss plate 42 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, so as to adjust the rise and fall of the device as a whole in the water, and solve the problem that the truss plate 42 is broken or damaged due to excessive stress when subjected to external force.

[0025] 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.

[0026] The third connecting plate 54 has a slot at one end opposite to the truss plate 42 , and there is an empty space between the third connecting plate 54 and the truss plate 42 to prevent the truss plate 42 from colliding or getting stuck when the third connecting plate 54 causes the truss plate 42 to swing.

[0027] In this embodiment, the driving member 10 can drive the first transmission rod 20 to perform rotational motion.

[0028] 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 , Attachment Figure 7 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.

[0029] 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.

[0030] 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.

[0031] Embodiment 3: 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 2 , Attachment Figure 5 , Attachment Figure 7 , Figure 8 As shown, the present embodiment has at least two trusses 42, which are connected by assembly plates 44. Concave grooves are provided on the surfaces of adjacent trusses 42, and the concave grooves can accommodate the assembly plates 44, so that after the assembly plates 44 are installed in the concave grooves, the assembly plates 44 can be flush with the surfaces of the trusses 42. Through holes are provided on the surfaces of the assembly plates 44, and the assembly plates 44 can be fixedly connected to the trusses 42 by fasteners. The adjacent trusses 42 can be split by removing the fasteners from the trusses 42, so that the number of trusses 42 used can be adjusted as needed.

[0032] The cross-section of the truss 42 is such that one end is larger than the other end, so that water has a certain diversion effect on the water body when it flows through the surface of the truss 42. In addition, the bottom surface of the truss 42 is provided with a slide groove 43, and the slide groove 43 is equipped with a connecting rod 45 that can slide relative to the slide groove 43. The connecting rod 45 and the non-connecting end of the slide groove 43 are provided with a float 46, and the float 46 is preferably a float ball.

[0033] By arranging connecting bars 45 and buoys 46 at the bottom of the truss 42, the fluid flowing through the bottom of the truss 42 can be appropriately diverted to prevent the fluid from flowing in a concentrated direction. When the fluid flows through the bottom of the truss 42, the buoys 46 and the connecting bars 45 are spaced apart from the truss 42. In this way, when the truss assembly 40 is located on the water surface and moves, the contact between the water surface waves and the connecting bars 45 and the buoys 46 can utilize the up and down floating of the connecting bars 45 and the buoys 46 relative to the waves to relatively reduce the impact of the waves on the truss 42, thereby ensuring the stability of the truss assembly 40 during its movement on the water surface. In addition, when the water flows through the connecting bars 45, the probability of partial change in the flow direction of the water body and generating water flow fluctuations or noise increases, which helps to drive the organisms below the truss assembly 40 to move in the rearward trawl direction to increase the capture success rate and prevent the organisms from obstructing the movement of the truss assembly 40 near the truss assembly 40.

[0034] Embodiment 4: This embodiment provides the following scheme based on the side-type Antarctic krill truss trawling water layer regulating truss equipment of Embodiment 1, see Attachment Figure 7 As shown, the upper end of the first connecting plate 51 is provided with a plug-in plate 511 that can be plugged therein, and the second rod 55 can pass through the upper end of the first connecting plate 51 and pass through the first connecting plate 51 and the plug-in plate 511, thereby forming a stable support for the second rod 55.

[0035] For further information, see attached Figure 7As shown, a mounting part 541 is provided on the side of the third connecting plate 54 , and the mounting part 541 is used to install the sensor assembly to obtain data of the device in water in real time.
