Description

Technical Field

[0001] The present application relates to the field of underwater detection equipment, and in particular to an underwater linear array stabilization component, a towed linear array and detection equipment. Background Art

[0002] At present, countries around the world are vigorously developing underwater detection equipment. Underwater detection equipment can be used to detect moving objects, such as organisms and human activities, and can therefore be widely used in scientific research and rescue activities. The underwater detection equipment is connected to a towed linear array. Multiple detection elements are arranged on the towed linear array to detect the sound waves generated by the water flow, thereby detecting targets.

[0003] During the deployment of the towed linear array, a sufficiently large flow resistance is required to pull the towed array into the water. If the part of the towed linear array that has entered the water cannot generate enough resistance, it will affect the deployment speed of the towed linear array and even affect the safety of the equipment.

[0004] After the towed linear array is completely submerged in the water, sufficient pulling force needs to be generated at the tail of the towed linear array to ensure that the entire towed linear array is in a nearly straight posture. This is of great significance for formation measurement and subsequent beamforming. At the same time, the unstable wake of the towed linear array will cause the tail to swing. This large-scale flow noise is one of the main reasons that affect the underwater detection performance of the towed linear array. Summary of the invention

[0014] Furthermore, the underwater linear array stabilization assembly also includes a mounting ring fixedly connected to the rod body; and one end of the stabilization frame away from the radial frame is fixedly connected to the mounting ring.

[0015] Furthermore, the surface of the mounting ring away from the rod body includes a groove portion; and one end of the stabilizing frame away from the radial frame is arranged in the groove portion.

[0016] Furthermore, the skeleton also includes a connecting frame; one end of the connecting frame is fixedly connected to the radial frame between the fixed end and the connecting end, and the other end is used to connect to the radial frame of the adjacent skeleton.

[0017] Furthermore, the frame also includes a connecting plate; the connecting plate extends around the rod body at the fixed end and is fitted and connected to the surface of the umbrella surface facing the rod body.

[0018] Furthermore, the underwater linear array stabilization assembly also includes a reinforcing plate; the reinforcing plate is arranged on the surface of the umbrella surface away from the connecting plate and is connected to the umbrella surface.

[0019] Furthermore, the underwater linear array stabilization assembly also includes a stabilization wing arranged at the second end; the stabilization wing is fixedly connected to the rod body; the number of the stabilization wings includes multiple, and the multiple stabilization wings are evenly distributed around the axis of the rod body.

[0023] It can be seen from the above embodiments that the underwater linear array stabilization component of the present application can produce different deformations according to different towing speeds, thereby changing the flow resistance generated by the underwater linear array stabilization component, and completing the formation stabilization of the towed linear array with adaptive speed. In this way, the underwater linear array stabilization component can ensure that the appropriate tension can be applied to the towed linear array at different speeds of the detection equipment. When the towed linear array begins to be deployed at sea, the underwater linear array stabilization component at the end of the towed linear array is first placed into the sea.

DETAILED DESCRIPTION

[0035] Here, the technical solutions in the embodiments (or "implementation methods") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0037] refer to Figure 1 The present application provides an underwater linear array stabilization assembly 100. The underwater linear array stabilization assembly 100 includes a rod body 1, an umbrella body 2, and a frame 3. The rod body 1 includes a first end 11 and a second end 12. The umbrella body 2 is formed by connecting a plurality of umbrella surfaces 21, and includes an opening side 22. The frame 3 connects the umbrella body 2 and the rod body 1 at the opening side 22, so that the opening side 22 faces the first end 11. Among them, one end of the umbrella surface 21 away from the opening side 22 abuts against the rod body 1, and can be deformed toward the second end 12.

[0038] The side of the umbrella body 2 of the underwater linear array stabilizing assembly 100 of the present application away from the first end 11 only abuts against the rod body 1, but is not directly connected. Therefore, when the inner side of the umbrella body 2 facing the rod body 1 is subjected to a force directed from the first end 11 to the second end 12, the umbrella cover 21 can bend and deform. When the underwater linear array stabilizing assembly 100 is working underwater, when the inner side of the umbrella body 2 facing the rod body 1 is impacted by the fluid flowing from the first end 11 to the second end 12, the umbrella cover 21 is deformed so that the fluid can leave the umbrella body 2 through the gap between the umbrella cover 21 and the rod body 1.

[0039] Combination Figure 2The present application also provides a towed linear array 200. The towed linear array 200 includes a cable 210, a detection element 220, and an underwater linear array stabilization assembly 100. The cable 210 includes an interface end 210a and an end 210b that are arranged opposite to each other. The end 210b is connected to the first end 11, so that the underwater linear array stabilization assembly 100 serves as the last working unit of the towed linear array 200. The detection element 220 is arranged between the interface end 210a and the end 210b and is electrically connected to the cable 210. When the towed linear array 200 is assembled in a detection device, the interface end 210a is electrically connected to a power supply of the detection device, thereby realizing power supply of the detection element 220.

[0040] The detection device can be a ship or an underwater vehicle. The towed linear array 200 moves with the detection device, so that the water flow exerts force on the umbrella surface 21 from the first end 11 to the second end 12. Figure 2 As shown by the blue arrow. Since the open side 22 of the parachute 2 faces the first end 11, the presence of the underwater linear array stabilizing assembly 100 increases the moving resistance of the towed linear array 200. In this way, when the towed linear array 200 begins to be deployed at sea, the underwater linear array stabilizing assembly 100 at the end 210b of the towed linear array 200 is first put into the sea, and the resistance between the underwater linear array stabilizing assembly 100 and the water provides pulling force for the towed linear array 200 to enter the water, ensuring that the towed linear array 200 enters the water better, improving the deployment efficiency while avoiding the danger of entanglement with the propeller of the detection equipment.

[0041] When the detection equipment is traveling, the resistance of the underwater linear array stabilization assembly 100 can reduce the swing amplitude of the end 210b of the towed linear array 200, improve the formation stability of the towed linear array 200, thereby reducing the flow noise in a large scale range, and further improving the detection accuracy of the towed linear array 200 and the detection equipment.

[0042] In addition, the underwater linear array stabilizing assembly 100 can also adjust the magnitude of the resistance generated according to the speed of the detection device. Specifically, when the detection device is traveling at a low speed, the force applied by the water flow to the umbrella 21 is small, so the deformation of the umbrella 21 away from the opening end is also small. When the speed of the detection device increases, the relative speed of the water flow and the underwater linear array stabilizing assembly 100 increases, so the force applied by the water flow to the umbrella 21 also increases, and the deformation of the umbrella 21 also increases.

[0043] It can be seen that the underwater linear array stabilization component 100 of the present application can produce different deformations according to different towing speeds, thereby changing the flow resistance generated by the underwater linear array stabilization component 100, and completing the formation stabilization of the towed linear array 200 with adaptive speed. In this way, the underwater linear array stabilization component 100 can ensure that the appropriate tension can be applied to the towed linear array 200 at different speeds of the detection equipment, avoiding damage to the underwater linear array stabilization component 100 when the flow rate is too high and the parachute 2 is insufficient in strength. In addition, the underwater linear array stabilization component 100 is connected to the end 210b of the cable 210, so the linear towed linear array 200 only needs to be provided with one underwater linear array stabilization component 100 to achieve the formation stabilization of the towed linear array 200, so that the cable 210 can arrange as many detection elements 220 as possible to achieve underwater detection.

[0044] In addition, the resistance adjustment of the underwater linear array stabilization component 100 of the present application does not need to be achieved through electric drive forms such as motors, but instead generates different deformations according to the speed of the water flow for adaptive adjustment, so it can be applied to different towed linear arrays 200.

[0045] Combination Figure 1 and Figure 3 , the number of skeletons 3 corresponds to the number of umbrella canopies 21, and each skeleton 3 is connected to each umbrella canopy 21. The skeleton 3 includes a radial frame 31 and a stabilizing frame 32. The radial frame 31 extends along the radial direction of the umbrella body 2, and includes a connecting end 311 connected to the umbrella canopy 21 and a fixed end 312 connected to the rod body 1. The stabilizing frame 32 is fixedly connected to the radial frame 31. One end of the stabilizing frame 32 is arranged between the first end 11 and the second end 12, and the other end extends obliquely toward the first end 11 and is connected to the rod body 1. In this way, a triangular structure is formed between the stabilizing frame 32, the rod body 1 and the radial frame 31, which is conducive to improving the connection stability of the skeleton 3, thereby ensuring the connection stability of the umbrella body 2 and the rod body 1.

[0046] Both the stabilizing frame 32 and the radial frame 31 can be directly welded and fixed to the rod body 1. Optionally, the underwater linear array stabilizing assembly 100 further includes a mounting ring 4 fixedly connected to the rod body 1. One end of the stabilizing frame 32 away from the radial frame 31 is fixedly connected to the mounting ring 4. When assembling the underwater linear array stabilizing assembly 100, the mounting ring 4 is first fixed to the rod body 1, and then the multiple skeletons 3 and the mounting ring 4 are fixed. The setting of the mounting ring 4 can play a positioning role to a certain extent, thereby facilitating the assembly of the multiple skeletons 3 to the target position and improving the structural accuracy of the underwater linear array stabilizing assembly 100.

[0047] Combination Figure 4In an optional embodiment, the surface of the mounting ring 4 away from the rod body 1 includes a groove portion 41. One end of the stabilizing frame 32 away from the radial frame 31 is arranged in the groove portion 41. The groove portion 41 can provide a positioning function for the connection position of the stabilizing frame 32, and the groove portion 41 can also increase the connection area of ​​the mounting ring 4 and the stabilizing frame 32, thereby improving the structural stability after welding.

[0048] The mounting ring 4 may be connected to the rod body 1 only by welding. Alternatively, a limiting portion (not shown) may be provided protrudingly on the rod body 1. The mounting ring 4 abuts against a side of the limiting portion toward the first end 11, thereby preventing the mounting ring 4 from moving along the axial direction of the rod body 1 due to the force from the water flow directed from the first end 11 to the second end 12.

[0049] Optionally, the number of the grooves 41 corresponds to the number of the frames 3. Alternatively, the number of the grooves 41 may be greater. In this way, the mounting ring 4 can be universally used in underwater linear array stabilization assemblies 100 with different numbers of frames 3, thereby improving the versatility of the mounting ring 4.

[0050] Furthermore, in order to improve the structural stability of the underwater linear array stabilization assembly 100, in some embodiments, the skeleton 3 further includes a connecting frame 33. One end of the connecting frame 33 is fixedly connected to the radial frame 31 between the connecting end 311 and the fixed end 312, and the other end is used to connect to the radial frame 31 of the adjacent skeleton 3. When multiple skeletons 3 are assembled, the adjacent skeletons 3 are connected through the connecting frame 33. And the connecting frame 33 is arranged between the connecting end 311 and the fixed end 312, so when multiple skeletons 3 are connected, the connecting frame 33 can provide structural support at the middle section of the skeleton 3 to prevent the skeleton 3 from being damaged by radial force at the middle section.

[0051] In the embodiment where the connecting frame 33 is connected to the radial frame 31 of the adjacent frame 3, the connecting frame 33 may simply rest against the adjacent frame 3, or may be fixedly connected by welding, thereby further improving the structural strength of the underwater linear array stabilization assembly 100.

[0052] The connection between the frame 3 and the canopy 21 can be achieved by welding the connecting end 311 and the canopy 21. Alternatively, the frame 3 may further include a connecting plate 34. The connecting plate 34 extends around the rod body 1 at the fixed end 312 and is connected to the surface of the canopy 21 facing the rod body 1. In other words, the connecting plate 34 and the canopy 21 are connected in surface-to-surface contact. When the water flow applies pressure to the side of the canopy 21 facing the rod body 1, the pressure causes the side of the canopy 21 close to the second end 12 to deform, and also generates a torque on the side of the canopy 21 close to the first end 11. If the connection stability between the canopy 21 and the frame 3 is insufficient, the underwater linear array stabilization assembly 100 may cause the canopy 21 and the frame 3 to separate when the detection equipment is at a high speed. In this embodiment, by providing the connecting plate 34, the underwater linear array stabilization assembly 100 can increase the connection area between the canopy 21 and the connecting plate 34, and increase the connection strength between the canopy 21 and the frame 3, so that the underwater linear array stabilization assembly 100 can be applied to detection equipment with different speeds.

[0053] It should be noted that the connecting plate 34 extends around the rod body 1, which can be understood as extending in an arc manner, so as to extend with the arc-shaped end surface of the umbrella body 2. Alternatively, the connecting plate 34 can be extended along a straight line, which is a tangent direction of the umbrella body 2, thereby reducing the processing difficulty and processing accuracy requirements of the connecting plate 34.

[0054] Combination Figure 3 and Figure 5 Optionally, the connecting plate 34 includes a plurality of frame assembly holes 341, and the umbrella cover 21 includes a plurality of umbrella assembly holes 211. When connected, the umbrella assembly holes 211 correspond to the frame assembly holes 341, so that the umbrella cover 21 and the frame 3 can be connected by fasteners such as bolts. The number of umbrella assembly holes 211 and frame assembly holes 341 can correspond one to one. Alternatively, the number of frame assembly holes 341 can be more, so that the frame 3 can be universally connected to umbrella covers 21 of different sizes.

[0055] Since the umbrella body 2 needs to withstand the impact of the water flow, the umbrella body 2 needs to have sufficient strength, otherwise it will be easily damaged. At the same time, since the umbrella body 2 needs to be deformed to adapt to the impact of the water flow at different speeds, the umbrella body 2 also needs sufficient deformability. In an optional embodiment, the umbrella cover 21 is made of beryllium bronze material. Beryllium bronze material has good elasticity and good fatigue resistance and stress relaxation resistance. In addition, beryllium bronze material has good corrosion resistance, so the underwater linear array stabilization assembly 100 can also maintain the stability of the material when the detection equipment is used for ocean detection.

[0056] The elasticity of the umbrella body 2 can be optimized by reducing the material thickness. However, the reduction in material thickness makes it easy for the umbrella surface 21 to be damaged by the fastening force applied by the fasteners when the connecting plate 34 and the umbrella surface 21 are connected by the fasteners.

[0057] Therefore, combined with Figure 6 In some optional embodiments, the underwater linear array stabilization assembly 100 further includes a reinforcing plate 5. The reinforcing plate 5 is disposed on the surface of the umbrella surface 21 away from the connecting plate 34 and is connected to the umbrella surface 21. The thickness of the reinforcing plate 5 may be greater than the thickness of the umbrella surface 21, so that its structural strength is better. Alternatively, the reinforcing plate 5 may be made of a material that is stronger than the strength of the umbrella surface 21. When the umbrella body 2 and the frame 3 are connected by fasteners, the reinforcing plate 5 includes a plurality of plate assembly holes 51. The plate assembly holes 51 correspond to the frame assembly holes 341 and the umbrella assembly holes 211, respectively. In this way, the reinforcing plate 5, the umbrella surface 21 and the frame 3 can be connected by fasteners. When the assembler tightens the fasteners, the pressure applied by the fasteners to the umbrella surface 21 is buffered by the reinforcing plate 5, so the pressure applied by the fasteners to the umbrella surface 21 is reduced, thereby ensuring the assembly yield of the underwater linear array stabilization assembly 100.

[0058] Of course, the connecting plate 34, the umbrella body 2 and the reinforcing plate 5 can also be fixedly connected by welding, and the present application does not limit this.

[0059] Optionally, the skeleton 3 may be provided with a reinforcing structure between the connecting plate 34 and the radial frame 31. One end of the reinforcing structure is connected to the connecting plate 34, and the other end is connected to the radial frame 31. It can be seen that a triangular structure is formed between the reinforcing structure, the connecting plate 34 and the radial frame 31, which is conducive to improving the connection stability of the connecting plate 34 and the radial frame 31.

[0060] When the connection end 311 of the radial frame 31 is disposed at the middle position of the connection plate 34 , that is, when the radial frame 31 and the connection plate 34 form a T-shaped structure, the radial frame 31 may have reinforcement structures on both sides.

[0061] In the embodiment where the end of the connecting plate 34 is connected to the connecting end 311 of the radial frame 31, that is, when the radial frame 31 and the connecting plate 34 form an L-shaped structure, the reinforcing structure is arranged between the connecting plate 34 and the radial frame 31. Further, the reinforcing structure can also be arranged on both sides of the radial frame 31, and the reinforcing structure on one side connects the radial frame 31 and the connecting plate 34, and the reinforcing structure on the other side connects the radial frame 31 and the connecting plate 34 of the adjacent frame 3. In this way, the connection strength and connection stability between the adjacent frames 3 can be further improved.

[0062] In order to improve the stability of the underwater linear array stabilization component 100 itself, in some optional embodiments, the underwater linear array stabilization component 100 further includes a stabilization wing 6 disposed at the second end 12. The stabilization wing 6 is fixedly connected to the rod body 1. The number of stabilization wings 6 includes multiple stabilization wings 6, and the multiple stabilization wings 6 are evenly distributed around the axis of the rod body 1. The arrangement of the stabilization wing 6 can improve the axial stability of the underwater linear array stabilization component 100, and prevent the underwater linear array stabilization component 100 from rolling under the impact of the water flow, thereby affecting the detection precision and accuracy of the detection element 220.

[0063] refer to Figure 7 The second end 12 of the rod body 1 may be provided with a conical surface 14. The conical surface 14 can improve the longitudinal stability of the underwater linear array stabilizing assembly 100, and also help to evenly distribute the water pressure and enhance the structural strength. The stabilizing wing 6 is connected to the conical surface 14.

[0064] In the above-mentioned embodiments, the resistance value that the underwater linear array stabilizing assembly 100 can provide can be adjusted by adjusting the area of ​​the umbrella surface 21 and the number of the skeletons 3. In addition, the reduction in the volume of the umbrella body 2 and the number of the skeletons 3 can also reduce the volume of the underwater linear array stabilizing assembly 100, thereby improving the convenience during deployment.

[0065] In order to improve the connection convenience between the underwater linear array stabilization component 100 and the cable 210, the underwater linear array stabilization component 100 may include a lifting ring 7 arranged at the first end 11. In this way, a hook may be provided at the end 210b of the cable 210, so as to realize the rapid disassembly and assembly of the underwater linear array stabilization component 100. The lifting ring 7 may be welded to the rod body 1. Alternatively, a connecting hole 13 is provided at the first end 11 of the rod body 1, and the lifting ring 7 is threadedly connected to the rod body 1 through the connecting hole 13. Since the underwater linear array stabilization component 100 works under the water surface, it needs to have a certain buoyancy. Therefore, the rod body 1 may be set to be hollow, and the hollow cavity may be processed through the connecting hole 13. Then, the connecting hole 13 may not only be used as the processing position of the hollow cavity, but also as the connecting hole 13 of the lifting ring 7. It can be seen that this setting method can improve the structural utilization rate of the underwater linear array stabilization component 100.

[0066] In the embodiment where the lifting ring 7 and the rod body 1 are connected through the connecting hole 13, a spring washer or threaded glue may be provided between the lifting ring 7 and the rod body 1 to improve the connection strength between the lifting ring 7 and the rod body 1. The underwater linear array stabilization assembly 100 may be directly connected to the cable 210, or assembled to the towing linear array 200 through a rope structure such as a Kevlar rope. The present application is not limited to this.

[0067] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
