Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fishing trawl net, in particular to a side-mounted krill trawl boom water layer adjustment truss equipment. BACKGROUND

[0002] The trawl boom is a commonly used fishing trawl net equipment for towing the trawl net to move during marine fishing. The existing trawl boom trawl net is used for krill fishing. The trawl boom carries the trawl net. The trawl boom is connected to the towing system of the fishing boat through the towing cable. The trawl boom trawl net is towed by the fishing boat to sweep the sea for fishing. The existing trawl boom trawl net can only passively control the water level depth by controlling the length of the towing cable and the sailing speed of the fishing boat, and cannot realize the active diving adjustment function.

[0003] In order to solve the problem of trawl boom diving adjustment, the existing technology provides a variety of solutions. For example, the existing technology CN114766442B discloses a kind of Antarctic krill trawl depth quick adjustment power trawl boom based on intelligent regulation and control. The device includes a trawl boom body, a connecting rod body is arranged beside the trawl boom body, and an adjusting rod is arranged at both ends of the trawl boom body. One end of each adjusting rod is fixedly connected with the connecting rod body. The upper and lower sides of the trawl boom body are provided with connecting assemblies. Each connecting assembly includes a plurality of connecting pieces. The side of the trawl boom body is provided with an adjusting mechanism. The adjusting mechanism includes a mounting shell, an adjusting assembly, a driving assembly and a power generation assembly. The small design of the adjusting mechanism of the device is more convenient for disassembly and maintenance, reduces the cost, and the equipment is not easy to be damaged after the structure is simplified. For example, the existing technology DK179265B1 discloses a trawl door for trawling fish. The trawl door has an upper frame, a lower frame and an intermediate frame. The upper frame, the lower frame and the intermediate frame define an intermediate frame between the upper frame and the lower frame, thereby forming an upper portion. Panels of a wing surface structure are provided, which are stacked on each other and connected to the frame at their respective ends. There is no movable and remotely controllable baffle installed under any panel. GB2161351 describes a net panel / trawl door that includes a mounting frame that can include an upper longitudinally extending end member formed by a panel and a lower longitudinally extending end member formed by a box keel section. The device can solve the problem that a higher attack angle is required at a slower towing speed to obtain a large enough resistance-induced force vector required for stable trawl door at a slower towing speed. However, the above-mentioned existing technologies still have room for improvement in terms of how to improve the trawl boom diving adjustment function in the trawl boom trawl operation. SUMMARY

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figures 1-8 As shown, a side-mounted Antarctic krill trawl water layer regulating truss equipment includes a truss assembly 40, which has a truss plate 42. The truss plate 42 is a plate structure, and the truss plate 42 has a rotating rod 41 that runs through both ends of the truss plate 42. The two ends of the truss plate 42 are connected to a second connecting plate 52 through the rotating rod 41. The present invention allows the truss plate 42 to rotate relative to the second connecting plate 52. Specifically, the rotating rod 41 and the second connecting plate 52 are rotatably connected. In this way, the direction of the force of the truss plate 42 on the water flow can be controlled by controlling the rotation of the truss plate 42 relative to the second connecting plate 52. This controls the rise or fall of the entire device in the water. The above solution simplifies the existing complex regulating equipment. 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.

[0028] The second connecting plate 52 side has a fourth plate body 521 with an arc-shaped sliding groove, and the truss plate 42 two ends have sliding blocks connected with the arc-shaped sliding groove. The fourth plate body 521 and the sliding block on the side of the truss plate 42 are matched to realize the rotation range control of the truss plate 42, so as to solve the problem that the rotation amplitude 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 equipment failure driving the truss plate 42 to rotate, the arc-shaped sliding groove and the sliding block can passively limit the rotation range of the truss plate 42. It is emphasized that the cooperation of the arc-shaped sliding groove and the sliding block relatively enhances the connection relationship between the side surface of the truss plate 42 and the second connecting plate 52. The shaking or deformation probability 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 object contact or consumed by the sliding of the truss plate 42 relative to the arc-shaped sliding groove.

[0029] The second connecting plate 52 is connected by at least two second rod bodies 55, and the second rod bodies 55 are connected by the first rod body 53. The axis of the first rod body 53 and the axis of the second rod body 55 have an included angle. A plurality of second rod bodies 55 are used to connect and fix adjacent second connecting plates 52. In this way, a containing space can be formed between two second connecting plates 52, and the containing space is further limited by the second rod body 55 and the first rod body 53. In this way, the truss plate 42 can be prevented from moving out of the containing space, and vice versa. The second rod body 55 and the first rod body 53 on the inside of the truss plate 42 form a protection, avoiding the damage of the truss plate 42 caused by the impact of objects in the sea or water body, especially the damage of the truss plate 42 caused by the continuous impact of some fish during the sea catching process. The second rod body 55 and the first rod body 53 provided help to generate noise around the truss plate 42 by the action of water flow, so as to drive away the organisms around the truss plate 42 and reduce the probability of damage caused by the impact of organisms. In addition, the second rod body 55 and the first rod body 53 provided enhance the overall structural strength of the device and help to ensure the stable state of the device working in the water.

[0030] The girder plate 42 is provided with the adjusting assembly 30, the adjusting assembly 30 includes the assembly box 31 with a containing space, the assembly box 31 is built-in rotatable turbine 32, the turbine 32 side is connected with the same shaft screw 36, the girder plate 42 surface is provided with through hole, the through hole is provided with connecting base plate 34 in the up and down direction respectively, the connecting base plate 34 is hinged with the girder plate 42 on one side of through hole through connecting block 37, the connecting base plate 34 is provided with first through slot, the screw 36 can be moved relative to the first through slot, under the action of turbine 32, the screw 36 is rotated, in turn, can drive the girder plate 42 to swing up and down, so as to realize the overall adjustment of the device in the water, wherein the connecting block 37 and the girder plate 42 are hinged, which can solve the problem that the girder plate 42 is broken or damaged due to excessive stress when the girder plate 42 is subjected to external force, specifically, when the girder plate 42 is in contact with the water body during movement in the water body, the girder plate 42 is continuously impacted by the water body, and when the upward lifting force or downward pressure is suddenly applied to the girder plate 42, the girder plate 42 is prone to deformation or damage in the area subjected to the upward lifting force or downward pressure, the connecting block 37 and the girder plate 42 of the present application are hinged, the upward lifting force or downward pressure is applied to the connecting base plate 34 first, and then transmitted to the girder plate 42, so as to solve the problem of regional deformation or damage of the girder plate 42 when subjected to upward and downward lifting.

[0031] The assembly box 31 is provided with a worm 33 matched with the turbine 32, and the worm 33 is connected with a first transmission rod 20 coaxial with the worm 33. The first transmission rod 20 can rotate. Under the action of the power mechanism, the first transmission rod 20 rotates, and the first transmission rod 20 is connected with the worm 33 through a shaft coupling, so that the worm 33 rotates to drive the turbine 32 to rotate.

[0032] The bottom surface of the girder plate 42 is provided with an auxiliary plate group 35, the auxiliary plate group 35 has an auxiliary horizontal plate arranged parallel to the girder plate 42 and having a spacing distance, the auxiliary horizontal plate is provided with a nut matched with the screw 36, the both ends of the auxiliary horizontal plate are provided with vertical plates, the vertical plates are provided with connecting shafts on the side surfaces, the connecting shafts are provided with rotating connecting rods connected therewith, and the rotating connecting rods are connected with the connecting base plate 34. The auxiliary plate group 35 is connected with the screw 36, the rotating movement of the screw 36 can drive the up and down displacement of the auxiliary plate group 35, in turn, can drive the up and down displacement of the connecting base plate 34, so as to realize the overall adjustment of the device in the water, and solve the problem that the girder plate 42 is broken or damaged due to excessive stress when the girder plate 42 is subjected to external force.

[0033] The side of the assembly box 31 is connected to the third connecting plate 54. The third connecting plate 54 has a connection and mounting hole for assembly with the second rod 55. The surface of the third connecting plate 54 is perpendicular to the axis of the second rod 55. The assembly box 31 is limited by the second rod 55 to ensure that the assembly box 31 does not move and the position of the lead screw 36 remains unchanged. The nut that mates with the lead screw 36 drives the auxiliary plate assembly 35 to move.

[0034] The third connecting plate 54 has a slot at one end relative to the truss 42, and there is a gap between the third connecting plate 54 and the truss 42 to prevent the truss 42 from colliding or getting stuck when the third connecting plate 54 causes the truss 42 to swing.

[0035] In this embodiment, the driving component 10 can drive the first transmission rod 20 to rotate.

[0036] Example 2:

[0037] This embodiment, based on the side-mounted Antarctic krill trawl truss equipment of Embodiment 1, provides the following scheme, see appendix. Figure 1 Appendix Figure 3 Appendix Figure 7 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.

[0038] 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.

[0039] 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.

[0040] Example 3:

[0041] The embodiment is based on the equipment of the water layer adjusting truss of the side-by-side Euphausia superba truss pole trawl net operation in embodiment 1, and provides the following scheme, as shown in Figs. 1-3. Figure 2 , Figs. 1-3. Figure 5 , Figs. 1-3. Figure 7 , Figure 8 The truss plates 42 in the embodiment have at least two, and the truss plates 42 are connected through the assembly plate body 44. The adjacent truss plates 42 are provided with recessed groove bodies on the surfaces, which can accommodate the assembly plate body 44. After the assembly plate body 44 is installed in the recessed groove body, the assembly plate body 44 can be flush with the surface of the truss plate 42. The surface of the assembly plate body 44 is provided with a through hole, and the assembly plate body 44 and the truss plate 42 can be fixedly connected through a fastener. The adjacent truss plates 42 can be separated by disassembling the fastener from the truss plate 42. In this way, the number of truss plates 42 can be adjusted as needed.

[0042] The cross section of the truss plate 42 is larger at one end than at the other end, so that the water flow has a certain flow guiding effect on the water body during the process of flowing through the surface of the truss plate 42. In addition, the bottom surface of the truss plate 42 is provided with a sliding groove 43, and the sliding groove 43 is provided with a connecting strip rod 45 which can slide relative to the sliding groove 43. The connecting strip rod 45 is provided with a float 46 at the non-connected end of the sliding groove 43. The float 46 is preferably a floating ball.

[0043] The connecting strip rod 45 and the float 46 can appropriately distribute the fluid flowing through the bottom of the truss plate 42, so as to avoid the fluid from flowing to a certain place. When the fluid flows through the bottom of the truss plate 42, the float 46 and the connecting strip rod 45 have a spacing distance relative to the truss plate 42. In this way, during the movement of the truss pole assembly 40 on the water surface, the contact between the water waves and the connecting strip rod 45 and the float 46 can reduce the impact of the waves on the truss plate 42 by the up and down floating of the connecting strip rod 45 and the float 46 relative to the waves, so as to ensure the stability of the truss pole assembly 40 during the movement on the water surface. In addition, the change of the water flow direction during the flow of the water through the connecting strip rod 45 increases the probability of water flow fluctuation or noise, so as to help drive the organisms under the truss pole assembly 40 to move to the rear trawl direction, increase the capture success rate, and avoid the organisms from causing the movement of the truss pole assembly 40 to be hindered.

[0044] Embodiment 4: The embodiment is based on the equipment of the water layer adjusting truss of the side-by-side Euphausia superba truss pole trawl net operation in embodiment 1, and provides the following scheme, as shown in Figs. 1-3. Figure 7 The upper end of the first connecting plate 51 is provided with a plug-in plate 511 which can be plugged with the first connecting plate 51. The second rod body 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, so as to stably support the second rod body 55.

[0045] Further, as shown in Figs. 1-3. Figure 7As shown, the third connecting plate 54 side is provided with fittings 541, fittings 541 for installing sensor components, to obtain real-time data in water device.
