Description

Technical Field

[0001] This invention relates to a modular support structure, specifically an anti-torsional modular support structure for double-cone array installation, belonging to the field of structural engineering technology. Background Technology

[0002] The biconical array is an important research direction in the field of underwater target radiated noise measurement technology. To achieve good measurement results, a stable and reliable rigid support structure is needed to install the biconical array, ensuring the accurate spatial relative position of each hydrophone element and the safety of the underwater system.

[0003] However, due to the acoustic characteristics of biconical arrays, there cannot be too much acoustic obstruction in the central dense array element area of ​​the biconical array, and the biconical array itself has torsional characteristics and internal tension. Therefore, the rigid support structure is required to use smaller rods in the middle array element area, and the structural strength must be able to resist the torsional characteristics of the biconical array. Summary of the Invention

[0004] In view of this, the present invention provides a torsion-resistant modular support structure for the installation of a biconical array. The modular structure design can ensure the accuracy of the biconical array elements, resist the torsional characteristics of the biconical array, and ensure sufficient strength and stability under large size.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a torsion-resistant modular support structure for installation of a double-cone array, comprising: a circular frame, an anti-torsion component, and a reinforcing connection component;

[0006] The two circular ring frames are coaxially opposite each other, and several sets of anti-torsion components are evenly distributed between the two circular ring frames along the circumference; the anti-torsion components that are adjacent along the circumference are connected by the reinforcing connection components.

[0007] The double-cone array is installed inside the annular space formed by the anti-torsion component and the reinforcing connection component, with its two ends respectively connected to the corresponding ends of the circular frame.

[0008] As a preferred embodiment of the present invention, the circular frame includes: two circular skeletons, a support column, a circular skeleton, a buckling-resistant bar, a converging circular ring A, a beam assembly, a reinforcing beam, and an umbrella-shaped support;

[0009] The two circular skeletons are coaxially spaced apart and connected together by a number of support columns evenly spaced circumferentially between them to form the main skeleton structure.

[0010] Two circular skeletons are circular skeleton A and circular skeleton B, with circular skeleton A located outside circular skeleton B. A plurality of buckling-resisting rods are evenly spaced circumferentially on the inner ring surface of circular skeleton A. The other ends of the buckling-resisting rods converge at a converging ring A. The converging ring A is coaxial with circular skeleton A and located outside circular skeleton A. Adjacent buckling-resisting rods are connected by struts, thereby forming an umbrella-shaped support by connecting several struts end to end.

[0011] A crossbeam assembly and a reinforcing crossbeam are welded to the inner ring surface of the circular frame B. The crossbeam assembly and the reinforcing crossbeam are arranged in a cross shape in the plane of the circular frame B.

[0012] The end face of the circular frame B is provided with several positioning holes for connecting the double cone array.

[0013] In a preferred embodiment of the present invention, the beam assembly includes a long beam, a vertical support, an oblique support A, and a converging ring B;

[0014] Two long crossbeams are arranged side by side, and each end of the long crossbeam is welded to the two opposite sides of the inner ring surface of the circular frame B through a connecting plate A. A converging ring B is set at the center of the long crossbeam. The converging ring B is coaxial with the converging ring A and is located between the converging ring A and the circular frame B. The two long crossbeams are connected to the converging ring B through several vertical supports. The outer ring surface of the converging ring B is symmetrically provided with diagonal supports A. The other end of the diagonal supports A is connected to the connecting plate A at the corresponding end of the long crossbeam.

[0015] As a preferred embodiment of the present invention, the reinforcing beam comprises a plurality of short beams;

[0016] One end of the short crossbeam intersects the long crossbeam perpendicularly, and the other end is welded to the inner ring surface of the circular frame B; each of the short crossbeams is connected to the outer ring surface of the converging ring B through an oblique support B.

[0017] In a preferred embodiment of the present invention, the anti-torsion assembly includes four anti-torsion bars;

[0018] The four anti-torsion bars are connected by butterfly connectors to form a cross structure with a set included angle;

[0019] Several reinforcing connectors are provided at intervals along the length between the two anti-torsion bars located on the same side, and each anti-torsion bar has a connecting plate at its end for connection with the circular frame.

[0020] As a preferred embodiment of the present invention, eight sets of anti-torsion components are evenly spaced circumferentially between the two circular frame members;

[0021] In the anti-torsion component, the included angle of the cross structure is 17 degrees.

[0022] In a preferred embodiment of the present invention, two adjacent anti-torsion components are connected by a plurality of parallel reinforcing connection components distributed along the length direction, thereby forming multiple sets of circular supports.

[0023] In a preferred embodiment of the present invention, the reinforcing connection assembly includes: a connecting rod and a T-shaped clamp;

[0024] Both ends of the connecting rod are connected to the anti-torsion rods in the two adjacent anti-torsion components via T-shaped clamps; a reinforcing connection component is provided at the adjacent position of each reinforcing connector; and the butterfly connectors connected to the anti-torsion components are connected by a reinforcing connection component.

[0025] Beneficial effects:

[0026] (1) The support structure of the present invention supports the double cone array, which can ensure the theoretical array shape, array element accuracy and the angle of twist of the double cone array along the central axis.

[0027] (2) In the circular frame of the present invention, the buckling-resistant rods arranged in a conical radial shape and the umbrella-shaped support can enhance the overall stability of the structure and prevent the circular frame from buckling and deforming due to the centripetal component force when it is hoisted; at the same time, the buckling-resistant rods are conical radial shape, which can protect the internal equipment in the end face direction.

[0028] (3) The anti-torsion component in the support structure of the present invention can counteract the torsional characteristics of the double cone array itself, so that the structure can maintain its structural strength under the dual support of internal torsional force and external tensile force.

[0029] (4) In this invention, four anti-torsion rods are connected to form a cross structure by butterfly connectors. The design shape is not a traditional vertical structure, but a cross structure with a set angle. While ensuring that the whole structure can withstand the tension, it can also provide the support structure with anti-torsion ability. Attached Figure Description

[0043] The present invention will be further described in detail below with reference to specific embodiments.

[0044] This embodiment provides a torsion-resistant modular support structure for mounting a biconical hydrophone array, which is used to mount the biconical hydrophone array to form a biconical array, meeting the array element accuracy requirements and ensuring the safe and stable operation of the equipment.

[0045] like Figure 1 and Figure 2 As shown, the anti-torsion modular structure includes three main modules: a circular frame 1, an anti-torsion component 2, and a reinforcing connection component 3; the three main modules are connected by detachable bolts, and each module is internally connected by welding.

[0046] The circular frame 1 consists of two sets, symmetrically, coaxially, and parallelly installed at both ends of the modular structure; the circular frame 1 is the main load-bearing structure of the modular structure. Several sets of anti-torsion components 2 are evenly distributed circumferentially between the two circular frame modules 1. These anti-torsion components 2 not only ensure overall tensile strength but also provide anti-torsion capabilities for the supporting structure. Adjacent anti-torsion components 2 are connected circumferentially via reinforcing connection components 3; these reinforcing connection components 3 support the formed sets of anti-torsion components 2, enhancing structural stability. A double-cone array 5 is installed inside the supporting structure (within the annular space enclosed by the anti-torsion components 2 and the reinforcing connection components 3), located between the two circular frame modules 1.

[0047] As an example, the anti-torsion component 2 consists of eight groups.

[0048] The following sections will provide a detailed introduction to the circular frame 1, the anti-torsion component 2, and the reinforcing connection component 3.

[0049] like Figures 3-5 As shown, the circular frame 1 includes: two circular skeletons, support column 102, circular skeleton, anti-buckling bar 104, converging ring A105, crossbeam assembly 106, reinforcing crossbeam 107, and umbrella-shaped support 108.

[0050] In this example, the circular frame of the circular ring component 1 is forged and rolled from titanium alloy TC4 material with a rectangular cross-section of 60×60, with a maximum outer diameter of 4.03 meters. The two circular frames are coaxially spaced apart and connected together by a number of support columns 102 evenly distributed circumferentially between them, forming the main frame structure.

[0051] As an example, an M42 right-hand threaded hole is made on one ring skeleton, and an M42 left-hand threaded hole is made on another ring skeleton. Similarly, positive and negative threads are machined on both sides of the support column 102. The connection strength is ensured by combining threaded connection and welding.

[0052] For ease of description, let the two circular frames be circular frame A101 and circular frame B103, with circular frame A101 located outside circular frame B103. A plurality of buckling-resisting rods 104 are evenly distributed circumferentially on the inner ring surface of circular frame A101; the other ends of the buckling-resisting rods 104 converge at a converging ring A105; the converging ring A105 is coaxial with circular frame A101 and located outside circular frame A101. Thus, the circumferential surface between the converging ring A105 and circular frame A101 is a frustum-shaped surface, and the buckling-resisting rods 104 are arranged along the generatrix of this frustum-shaped surface, i.e., the buckling-resisting rods 104 are arranged in a conical radial pattern. One end of each buckling-resisting rod 104 is welded to the inner ring surface of circular frame A101, and the other end is welded to the outer ring surface of converging ring A105. Adjacent buckling-resisting rods 104 are connected by struts, thus forming an umbrella-shaped support 108 by connecting several struts end to end. In this example, eight buckling-resisting rods 104 are evenly spaced along the circumference, so the umbrella-shaped support 108 is an octagonal structure formed by connecting eight struts end to end. This part of the structure can enhance the overall stability of the structure and prevent the circular frame from buckling due to the centripetal force during hoisting. At the same time, the buckling-resisting rods 104 are conical and radial, which can protect the internal equipment in the end face direction and facilitate the fixing of data acquisition cables, etc.

[0053] A crossbeam assembly 106 and a reinforcing crossbeam 107 are welded to the inner ring surface of the circular frame B103 to prevent buckling deformation due to the centripetal force during hoisting; the crossbeam assembly 106 and the reinforcing crossbeam 107 are arranged in a cross shape in the plane of the circular frame B103. The crossbeam assembly 106 includes a long crossbeam 1061, vertical supports 1062, diagonal supports A1063, and a converging ring B1064. Two long crossbeams 1061 are arranged side by side, and each end of the two long crossbeams 1061 is welded to the two opposite sides of the inner ring surface of the ring frame B103 through a connecting plate A1065. The converging ring B1064 is set at the center of the long crossbeam 1061. The converging ring B1064 is coaxial with the converging ring A5 and is located between the converging ring A5 and the ring frame B103. The two long crossbeams 1061 are connected to the converging ring B1064 through several vertical supports 1062. The outer ring surface of the converging ring B1064 is symmetrically provided with diagonal supports A1063. The other end of the diagonal support A1063 is connected to the connecting plate A1065 at the corresponding end of the long crossbeam 1061. In this example, two diagonal supports A1063 are provided on each of the two opposite sides of the converging ring B1064.

[0054] The reinforcing beam 107 includes several short beams 1071. One end of each short beam 1071 intersects perpendicularly with the long beam 1061, and the other end is welded to the inner ring surface of the circular frame B103. In this example, four short beams 1071 are provided, arranged symmetrically in pairs along the long beam 1061. Each short beam 1071 is connected to the outer ring surface of the converging ring B1064 through a diagonal support B1072.

[0055] Several positioning holes are provided on the end face of the circular frame B103 for connecting the double cone array 5.

[0056] like Figure 6 As shown, the anti-torsion component 2 includes four anti-torsion rods 201, a butterfly connector 202, and multiple reinforcing connectors 204. The anti-torsion rods 201 and the butterfly connector 202 are connected by threads, while the other parts are connected by welding. The four anti-torsion rods 201 are connected by the butterfly connector 202 to form a cross structure. The design shape is not a traditional vertical structure, but a 17-degree cross structure (that is, the included angle between two anti-torsion rods 201 on the same side is 17 degrees). While ensuring that the whole structure can withstand tensile force, it can also provide anti-torsion capability for the supporting structure.

[0057] There are two reasons for adopting this structural design for the anti-torsion component 2: First, after designing the overall mechanism based on the dimensions of the double-cone array, it was found that the overall structure would reach a height of over 10 meters with a huge span. The deflection of a single rod structure could not meet the design requirements, so four anti-torsion rods and butterfly connectors were designed to meet the structural strength requirements. Second, the double-cone array 5 is installed inside the support structure and is installed in a double-cone twisted configuration, which means that the force inside the support structure will be torsional. This makes the traditional vertical structure unable to meet the requirements, so a 17-degree cross structure was designed based on the actual dimensions.

[0058] Several reinforcing connectors 204 are provided at intervals along the length of two anti-torsion bars 201 on the same side for connection. Each anti-torsion bar 201 has a connecting plate 203 at its end for connection with the circular frame 1, such as... Figure 7 As shown. In this example, the two anti-torsion bars 201 on the same side are connected by three reinforcing connectors 204 of unequal length. The anti-torsion bars 201 and the reinforcing connectors 204 are all bars with a diameter of 20-30mm.

[0059] Two anti-torsion rods 201 at one end of the anti-torsion component 2 are connected to one of the circular frame 1 via a connecting plate 203, and two anti-torsion rods 201 at the other end are connected to another circular frame 1 via a connecting plate 203. The eight anti-torsion components 2 are evenly spaced along the circumference of the circular frame 1.

[0060] The anti-torsion component 2 and the circular frame 1 are connected by bolt group 4 on the connecting plate 203. The connecting plate 203 has through holes, and the circular frame 1 has threaded holes. Spring washers, flat washers, and bolts are sequentially inserted from the bottom side of the connecting plate 203. Nuts are also provided on one side of the circular frame 1. This connection method effectively ensures the connection strength between modules. Furthermore, ribs 205 are provided on the connector 204 to achieve structural reinforcement.

[0061] The reinforcing connection component 3 is used in conjunction with the reinforcing connector 204 in the anti-torsion component 2 to support the eight sets of anti-torsion components 2 after molding, thereby enhancing structural stability. Figure 8 As shown, after the two circular frame 1 and eight anti-torsion components 2 are fixed, the two adjacent anti-torsion components 2 are connected by the reinforcing connection component 3.

[0062] In this example, the reinforcing connection assembly 3 includes a connecting rod 302 and a T-shaped clamp 301. Both ends of the connecting rod 302 are connected to the anti-torsion rods 201 of two adjacent anti-torsion assemblies 2 via the T-shaped clamps 301, thereby achieving a reinforcing connection of the anti-torsion assemblies 2. Figure 8 As shown, the butterfly connectors 202 of the connected anti-torsion components 2 are connected by a reinforcing connector 3. Adjacent anti-torsion components 2 are connected by several parallel reinforcing connectors 3, thus forming multiple sets of circular supports. This ensures the structural stability of the anti-torsion components 2 under large-span horizontal conditions, during vertical placement, and during marine testing, guaranteeing that the anti-torsion components do not deform under stress. The connecting rod 302 is a bar with a diameter of 20-30mm.

[0063] As an example, a reinforcing connection component 3 is provided at an adjacent position to each reinforcing connector 204; thereby forming seven sets of circular supports.

[0064] Both the anti-torsion component 2 and the reinforcing connection component 3 are designed with rods of 20-30mm in diameter, connected in a cross-structure, and have a small cross-sectional area, thus avoiding uncorrectable sound blockage in the central dense array element area. Tests show that this structural form of the anti-torsion component 2, with a span of nearly 10 meters and the anti-torsion rod 201 having a diameter of only 20-30mm, and the seven sets of circular supports formed by the reinforcing connection group, can ensure the deflection of the anti-torsion component and the stability of the overall structure.

[0065] During sea trials, the structure will be in a vertical position with a maximum height of 10073mm. After entering the water, it will be kept in a "pull-up and drop-down" state using floats and counterweights. The structure can withstand extremely strong tensile strength, ensuring that the double-cone array formation remains within the error range.

[0066] The installation steps for this modular support structure are as follows:

[0067] (1) First, fix the two sets of circular ring frames 1 onto the auxiliary fixture. The overall installation of this structure requires the use of auxiliary fixtures. The purpose of the auxiliary fixtures is to fix the two sets of circular ring frames 1 to ensure their coaxiality, parallelism and distance tolerance.

[0068] (2) Fixing anti-torsion component 2: Connect eight anti-torsion components 2 in sequence between the two sets of circular frame 1, and connect them through bolt group 4. Use a torque wrench to pre-tighten all bolts to the pre-calculated torque value range.

[0069] (3) Fixing and reinforcing connection component 3: Fix several connecting rods 302 to two adjacent anti-torsion components 2 by using T-type clamps 301, and tighten the bolts on the T-type clamps 301 to complete the connection.

[0070] (4) Finally, the double-cone array 5 is connected to the pre-machined positioning holes of the circular frame 1 according to the theoretical array angle through threaded connection, thus completing the double-cone array forming work. Figure 9 As shown, the double cone array 5 is installed inside the support structure (inside the annular space enclosed by the anti-torsion component 2 and the reinforcing connection component 3), and is located between the two circular frames 1 at both ends.

[0071] In summary, the invention includes, but is not limited to, the above embodiments. Any equivalent substitutions or partial improvements made under the spirit and principles of this invention shall be considered to be within the protection scope of this invention.
