Description

Technical Field

[0001] The present invention belongs to the field of connecting structures, and particularly relates to an arc-shaped semi-automatic connecting structure for a detachable double-hull target ship. Background Art

[0002] Existing target ships are usually retired warships. For example, small warships such as Type 037 anti-submarine corvettes, Type 62 gunboats, and Type 6610 minesweepers are used as target ships after retirement. After some structures of these target ships converted from warships are damaged during a single test, only the whole ship can be recovered or the slightly damaged area can be repaired and then put into use to carry out the practicality test of weapons and equipment. There are problems such as low repair efficiency, inability to adapt to the modern battlefield environment and actual combat requirements. And using retired warships as target ships has the problem of fixed target size, unable to effectively simulate the ship structures of various target scales, which affects the actual combat exercise effect to a certain extent and limits the comprehensiveness of test data.

[0003] In addition, most of the existing semi-automatic connecting structures of target ships are cube-shaped structures. During the connection process, it takes a long time to align the connecting parts and the fixing parts, and they can only be fixed in four degrees of freedom, with high operation difficulty, high time cost and low structural stability.

[0004] Therefore, an arc-shaped semi-automatic connecting structure for a target ship is needed, which can not only solve the problem of limited target ship size, but also solve the problems of high alignment accuracy requirements, long assembly time and low structural stability of existing connecting parts.

[0005] The invention patent with the patent number CN118705944A is a detachable double-hull target ship, which is a target ship formed by connecting two main hulls through a bow deck, a midship deck, a stern deck and a plate-frame connecting bridge located between the decks.

[0006] The invention patent with the patent number CN115705784A is a suspended double-hull target ship, which is composed of a hull deck, a suspension structure and two buoyancy monomers. The suspension structure is connected to the upper sides of the two buoyancy monomers, and the hull deck is installed on the suspension structure. Summary of the Invention

[0007] In view of this, in order to solve the problems that after the existing target ship is damaged, it can only be recovered as a whole ship, the damaged ship surface is repaired and then put into use again, resulting in low repair efficiency, high repair cost, inability to adapt to the modern battlefield environment and actual combat requirements, and the existing cube - type connection structure, which takes a long time to align the connecting parts and the fixing parts during the connection process, has high alignment accuracy requirements, and only has four degrees of freedom. The present invention provides an arc - shaped semi - automatic connection structure for a detachable catamaran target ship, which optimizes the traditional cube structure into an arc - shaped surface, optimizes the existing shell - type connection structure into a mortise - and - tenon connection structure, and controls the connection relationship between the fixing parts and the connecting parts by raising or lowering the semi - automatic buckle, so as to complete the rapid connection between structures and the rapid repair of damaged cabin sections. At the same time, two additional front - and - rear degrees of freedom restrictions are added to the four degrees of freedom to achieve all - round fixation of the structure.

[0008] To achieve the above object, the present invention adopts the following technical solutions: An arc - shaped semi - automatic connection structure for a detachable catamaran target ship, including a fixing part and an arc - shaped connecting part. Four buckle grooves are arranged on the upper and lower surfaces of the arc - shaped connecting part, and buckles are installed in the buckle grooves. A semi - arc - shaped protrusion is arranged on the side of the buckle and can move up and down along the buckle groove according to the connection needs. A pressure sensor is arranged on the back of the buckle. Upper and lower top plates are arranged on the upper and lower sides of the fixing part, and upper and lower limiting holes are arranged on the inner sides of the upper and lower top plates.

[0009] Furthermore, the buckle is in the shape of a claw hammer, and the semi - arc - shaped protrusion part of the claw hammer is a quarter - cylinder.

[0010] Furthermore, when the claw - hammer - shaped buckle descends to the bottom of the buckle groove, the right - angled lower surface of its quarter - cylinder can just be tangent to the upper surface of the arc - shaped connecting part.

[0011] Furthermore, the pressure sensor can receive a pressure signal from the buckle groove when the rounded surface of the quarter - cylinder of the buckle is subjected to pressure from the top plate of the fixing part, so as to control the buckle to continuously descend to the bottom of the buckle groove.

[0012] Furthermore, the fixing part includes a top plate, an upper limiting hole of the fixing part, a lower limiting hole of the fixing part, an upper top plate of the fixing part and a lower top plate of the fixing part. The upper and lower top plates of the fixing part are respectively installed above and below the top plate. The upper limiting hole of the fixing part is arranged on the inner side of the upper top plate of the fixing part, and the lower limiting hole of the fixing part corresponding to the upper limiting hole is arranged on the inner side of the lower top plate of the fixing part. The two sides of the top plate are the main cabin walls.

[0013] Furthermore, the top plate of the fixing part and the semi - arc - shaped protrusion arranged on the buckle can be linearly fitted to avoid structural stress concentration.

[0014] Furthermore, the arc-shaped connecting member includes an arc-shaped connecting member body, a semi-automatic buckle on the upper right of the connecting member, a semi-automatic buckle on the lower right of the connecting member, a semi-automatic buckle on the upper left of the connecting member, a semi-automatic buckle on the lower left of the connecting member, and four buckle grooves. Four buckle grooves are arranged inside the four corners of the arc-shaped connecting member body, and the semi-automatic buckle on the upper right of the connecting member, the semi-automatic buckle on the lower right of the connecting member, the semi-automatic buckle on the upper left of the connecting member, and the semi-automatic buckle on the lower left of the connecting member move up and down along the four buckle grooves respectively.

[0015] Furthermore, pressure sensors are arranged at the contact parts of the semi-automatic buckle on the upper right, the semi-automatic buckle on the lower right of the connecting member, the semi-automatic buckle on the upper left of the connecting member, and the semi-automatic buckle on the lower left of the connecting member with the arc-shaped connecting member body.

[0016] Compared with the prior art, the beneficial effects of the arc-shaped semi-automatic connection structure of the detachable catamaran target ship described in the present invention are as follows:

[0017] 1. The arc-shaped semi-automatic connection structure of the detachable catamaran target ship described in the present invention can reduce the docking difficulty through the arc surface when the damaged cabin section needs to be disassembled separately for repair or assembled, and improve the assembly and disassembly efficiency. The specific manifestation of this beneficial effect is that the arc-shaped protrusions on the side of the fixing member and the rounded corners of the semi-automatic buckle can effectively reduce the requirements for alignment accuracy of the two components in the left, right, upper, and lower directions, especially improve the smoothness of the connection process of each cabin section, save the target ship assembly and recovery time, and the mortise and tenon structure can ensure the overall stability of the connection structure.

[0018] 2. The present invention can also meet the function of the traditional semi-automatic target ship connection structure that when part of the hull is damaged, the damaged cabin section can be disassembled separately for repair and a brand-new cabin section with the same specifications can be installed to continue the test, ensuring its assembly efficiency and structural strength from three aspects: the accuracy required for disassembly and assembly, structural stability, and semi-automatic connection structure.

[0019] 3. The present invention optimizes the traditional cubic structure into an arc surface and optimizes the existing shell-type connection structure into a mortise and tenon connection structure. By controlling the connection relationship between the fixing member and the connecting member through the rising or falling of the semi-automatic buckle, the rapid connection between structures and the rapid repair of damaged cabin sections are completed, greatly reducing the docking difficulty.

[0020] 4. After the buckle enters the buckle groove, it cannot move left and right, front and back. Due to the design of the buckle in the up and down directions, it cannot slide either, adding additional front and back degree-of-freedom restrictions in the four degrees of freedom to achieve six-degree-of-freedom all-round fixation of the structure.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Refer to Figures 1-4 To illustrate this embodiment, an arc-shaped semi-automatic connection structure for a detachable catamaran target ship includes a fixing piece and an arc-shaped connecting piece. Four buckle grooves are provided on the upper and lower surfaces of the arc-shaped connecting piece, and buckles are installed in the buckle grooves. A semi-circular protrusion is provided on the side of the buckle and can move up and down along the buckle groove according to the connection needs. A pressure sensor 13 is provided on the back of the buckle. Upper and lower top plates are provided on the upper and lower sides of the fixing piece, and upper and lower limit holes are provided on the inner sides of the upper and lower top plates.

[0029] In the present invention, the upper and lower ends of the semi-automatic buckle of the connecting member and the upper and lower baffles of the fixing member squeeze and trigger the pressure sensor 13 on the back of the semi-automatic buckle, controlling the rise or fall of the claw-hammer-shaped semi-automatic buckle on the upper and lower surfaces of the arc-shaped connecting member, so that the claw-hammer-shaped semi-automatic buckle engages or disengages with the upper and lower limit holes provided on the upper and lower baffles of the fixing member, realizing the connection or separation of the connecting member and the fixing member.

[0030] The top plate of the fixing member and the semi-circular protrusion provided on the arc-shaped connecting member can be linearly fitted, effectively avoiding structural stress concentration.

[0031] In the connected state, the upper limit hole 3 of the fixing member, the upper right semi-automatic buckle 6 of the connecting member, and the lower right semi-automatic buckle 7 of the connecting member are engaged in a mortise and tenon manner, having high stability in six degrees of freedom.

[0032] In the connected state, the top plate 2 is tangent to the arc-shaped part of the arc-shaped connecting member body 5, without requiring alignment accuracy, which can reduce the docking difficulty.

[0033] The semi-automatic buckle of the arc-shaped connecting member is claw-hammer-shaped, and the protruding part of the claw-hammer is a quarter cylinder.

[0034] The four buckle grooves of the arc-shaped connecting member enable the four claw-hammer-shaped buckles to move up and down in the grooves. When the claw-hammer-shaped buckle descends to the bottom of the buckle groove, the right-angled lower surface of its quarter cylinder can just be tangent to the upper surface of the arc-shaped connecting member.

[0035] The upper and lower limit holes provided inside the upper and lower baffles of the fixing member can be fully engaged with the claw-hammer-shaped semi-automatic buckles on the upper and lower surfaces of the arc-shaped connecting member. The upper and lower buckles of the arc-shaped connecting member and the upper and lower limit holes of the fixing member form a complete fitting structure.

[0036] The pressure sensor provided on the back of the semi-automatic buckle can receive the pressure signal from the buckle groove when the rounded surface of the quarter cylinder of the semi-automatic buckle is subjected to the pressure from the top plate of the fixing member, thereby controlling the buckle to continuously descend to the bottom of the buckle groove.

[0037] The fixing member 10 includes a top plate 2, an upper limit hole 3 of the fixing member, a lower limit hole 4 of the fixing member, an upper top plate 8 of the fixing member, and a lower top plate 9 of the fixing member. The upper and lower parts of the top plate 2 are respectively provided with the upper top plate 8 of the fixing member and the lower top plate 9 of the fixing member. The upper limit hole 3 of the fixing member is provided inside the upper top plate 8 of the fixing member. The lower limit hole 4 corresponding to the upper limit hole 3 of the fixing member is provided inside the lower top plate 9 of the fixing member. Both sides of the top plate 2 are the bulkhead main body 1.

[0038] The arc-shaped connecting piece includes an arc-shaped connecting piece body 5, a semi-automatic upper right buckle 6 of the connecting piece, a semi-automatic lower right buckle 7 of the connecting piece, a semi-automatic upper left buckle 11 of the connecting piece, a semi-automatic lower left buckle 12 of the connecting piece, and four buckle slots. Four buckle slots are arranged inside the four corners of the arc-shaped connecting piece body 5. The semi-automatic upper right buckle 6 of the connecting piece, the semi-automatic lower right buckle 7 of the connecting piece, the semi-automatic upper left buckle 11 of the connecting piece, and the semi-automatic lower left buckle 12 of the connecting piece move up and down along the four buckle slots respectively.

[0039] Pressure sensors 13 are arranged at the contact parts between the semi-automatic upper right buckle 6, the semi-automatic lower right buckle 7, the semi-automatic upper left buckle 11, and the semi-automatic lower left buckle 12 of the connecting piece and the arc-shaped connecting piece body 5.

[0040] The present invention discloses an arc-shaped semi-automatic connection structure for a detachable catamaran target ship. The main innovation lies in an arc-shaped connection surface that can reduce the connection difficulty and the required alignment accuracy, and adopts a mortise and tenon connection, which can restrict the structure in six degrees of freedom. This is quite different from the structure style, principle, and specific functional effects involved in the invention patent with the patent number CN118705944A.

[0041] At the same time, the present invention is composed of a hull main body, a fixing piece, and an arc-shaped connecting piece. The fixing piece and the arc-shaped connecting piece can be connected in a mortise and tenon manner, which is quite different from the structure utilization rate and application range of the invention patent with the patent number CN115705784A.

[0042] Embodiment 1: Installation

[0043] The arc-shaped semi-automatic connection structure of the detachable catamaran target ship includes a fixing piece 10 and an arc-shaped connecting piece. The semi-automatic upper left buckle 11 of the connecting piece, the semi-automatic lower left buckle 12 of the connecting piece, the semi-automatic upper right buckle 6 of the connecting piece, and the semi-automatic upper left buckle 7 of the connecting piece are arranged above and below the arc-shaped connecting piece body 5. Pressure sensors 13 are arranged between the semi-automatic buckles and the buckle slots.

[0044] There are four semi-automatic buckle slots on the upper surface 14 and the lower surface 15 of the arc-shaped connecting piece body 5. Among them, the upper right buckle slot 18 of the arc-shaped connecting piece and the lower right buckle slot 19 of the arc-shaped connecting piece are taken as examples in this embodiment.

[0045] The arc-shaped convex arc surface 20 of the arc-shaped connecting piece body 5 is a smooth curved surface, and the upper surface 21 and the lower surface 22 of the arc-shaped convex are both horizontal planes.

[0046] The upper right buckle slot 18 and the lower right buckle slot 19 of the above-mentioned arc-shaped connecting piece can allow the semi-automatic buckles 6 and 7 to rotate downward and upward along the arc surface by a small angle until the upper plane of the semi-automatic buckle fillet is tangent to the upper surface 14 and the lower surface 15 of the arc-shaped connecting piece body 5.

[0047] During the installation of the connecting piece, the fixing piece bodies 10 on both sides move inwards simultaneously, and the front ends of the upper top plate 8 and the lower top plate 9 of the fixing piece contact and squeeze their respective semi-automatic buckles 6 and 7 simultaneously.

[0048] The pressure sensor 13 on the back of the semi-automatic buckle receives the pressure signal from the buckle groove, causing the semi-automatic buckle to rotate downward until the rounded plane is tangent to the upper and lower surfaces 14 and 15 of the arc-shaped connector body 5. At this time, the rounded lower cut surface of the semi-automatic buckle just contacts the upper and lower surfaces 21 and 22 of the arc-shaped protrusion, and the semi-automatic buckles 6 and 7 are fixed in this position.

[0049] The upper top plate 8 and the lower top plate 9 continue to move until the front ends contact each other. At this time, the top plate 2 just contacts the arc-shaped raised surface 20 of the arc-shaped connector body 5. When the top plate 2 is in complete linear contact with the arc-shaped raised surface 20, the semi-automatic buckles 6 and 7 pop up. At this time, the semi-automatic buckles 6 and 7 are engaged with the upper and lower limit holes 3 and 4 of the upper top plate 8 and the lower top plate 9.

[0050] The square surfaces 23 of the semi-automatic buckles 6 and 7 press against the upper and lower limit holes 3 and 4 of the upper top plate 8 and the lower top plate 9, so that the main body of the arc-shaped connector is firmly fixed.

[0051] After the arc-shaped connecting piece is fixed, until the front ends of the upper top plate 8 and the lower top plate 9 are in contact, the square surfaces 23 of the semi-automatic buckles 6 and 7 can support the upper and lower limit holes of the upper top plate 8 and the lower top plate 9, which can ensure that the fixing pieces on both sides do not slide in the horizontal and vertical directions.

[0052] Until the front ends of the upper top plate 8 and the lower top plate 9 are in contact and the semi-automatic buckles 6 and 7 are completely inserted into the upper and lower limit holes 3 and 4 of the upper top plate 8 and the lower top plate 9, it can be ensured that the compartments on both sides do not slide vertically, and complete restriction in six degrees of freedom is achieved at this time.

[0053] Example 2: Disassembly

[0054] The semi-automatic buckles 6 and 7 rotate downward along the arc surface at a small angle until the rounded plane is tangent to the upper and lower surfaces 14 and 15 of the arc-shaped connector body 5. At this time, the fixing pieces on both sides can slide to both sides until they are separated from the arc-shaped connector body 5.

[0055] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
