Description

Technical Field

[0001] This invention belongs to the field of connecting structures, and in particular relates to an arc-shaped semi-automatic connecting structure for a detachable catamaran target ship. Background Technology

[0002] Existing target ships are typically decommissioned vessels, such as the Type 037 submarine chaser, Type 62 gunboat, and Type 6610 minesweeper. These converted target ships, after suffering structural damage in a single test, can only be used for practical weapons testing by either complete ship recovery or repair of minor damage. This results in low repair efficiency and an inability to adapt to modern battlefield environments and combat requirements. Furthermore, using decommissioned ships as target ships presents the problem of fixed target sizes, failing to effectively simulate ship structures of various target scales, which to some extent affects the effectiveness of live-fire exercises and limits the comprehensiveness of test data.

[0003] In addition, the existing semi-automatic connection structure of target ships is mostly a cubic structure. The alignment of the connecting parts and the fixing parts during the connection process takes a long time, and the fixing can only be performed in four degrees of freedom. This makes the operation difficult, time-consuming, and structurally unstable.

[0004] Therefore, an arc-shaped semi-automatic connection structure for the target ship is needed, which can solve the problem of limited target ship size, as well as the problems of high alignment accuracy, long assembly time, and low structural stability of existing connectors.

[0005] The invention patent with patent number CN118705944A is a detachable catamaran target ship, which is a target ship connected by two main hulls through bow deck, midship deck, stern deck and plate frame connecting bridge located between each deck.

[0006] The invention patent with patent number CN115705784A is a suspended catamaran target ship, which consists of a hull deck, a suspension structure and two buoyancy units. The suspension structure is connected to the upper side of the two buoyancy units, and the hull deck is mounted on the suspension structure. Summary of the Invention

[0007] In view of this, to address the shortcomings of existing target ships, which require complete recovery and repair of the damaged decks after damage, resulting in low repair efficiency, high repair costs, inability to adapt to modern battlefield environments and combat requirements, and the drawbacks of existing cubic connection structures with time-consuming alignment of connectors and fasteners, high alignment accuracy requirements, and only four degrees of freedom, this invention provides an arc-shaped semi-automatic connection structure for a detachable catamaran target ship. It optimizes the traditional cubic structure into an arc-shaped surface and the existing shell-type connection structure into a mortise and tenon joint structure. The connection relationship between fasteners and connectors is controlled by the raising or lowering of semi-automatic latches, thereby achieving rapid connection between structures and rapid repair of damaged sections. Simultaneously, two additional forward and backward degrees of freedom are added to the four degrees of freedom, achieving omnidirectional structural fixation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an arc-shaped semi-automatic connection structure for a detachable catamaran target ship, comprising a fixing component and an arc-shaped connector. The upper and lower surfaces of the arc-shaped connector are provided with four snap-fit ​​grooves, and snap-fits are installed in the snap-fit ​​grooves. The snap-fits are provided with semi-arc-shaped protrusions on their sides, and can move up and down along the snap-fit ​​grooves as needed for connection. A pressure sensor is provided on the back of the snap-fits. The upper and lower sides of the fixing component are provided with upper and lower top plates, and the inner sides of the upper and lower top plates are provided with upper and lower limit holes.

[0009] Furthermore, the buckle is shaped like a ram's horn, and the semi-circular protrusion of the ram's horn is a quarter-cylinder.

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

[0011] Furthermore, the pressure sensor can receive a pressure signal from the buckle groove when the rounded corner surface of the quarter cylinder of the buckle is subjected to pressure from the top plate of the fastener, thereby controlling the buckle to continue to descend to the bottom of the buckle groove.

[0012] Furthermore, the fastener includes a top plate, a fastener upper limit hole, a fastener lower limit hole, a fastener upper top plate, and a fastener lower top plate. The top plate is equipped with the fastener upper top plate and the fastener lower top plate, respectively. The fastener upper limit hole is provided on the inner side of the fastener upper top plate, and the fastener lower limit hole is provided on the inner side of the fastener lower top plate at a position corresponding to the fastener upper limit hole. The two sides of the top plate are the bulkhead body.

[0013] Furthermore, the top plate of the fastener and the semi-circular protrusion on the buckle can fit in a linear fit, avoiding structural stress concentration.

[0014] Furthermore, the arc-shaped connector includes an arc-shaped connector body, an upper right semi-automatic buckle, a lower right semi-automatic buckle, an upper left semi-automatic buckle, a lower left semi-automatic buckle, and four buckle slots. The four corners of the arc-shaped connector body are provided with four buckle slots. The upper right semi-automatic buckle, the lower right semi-automatic buckle, the upper left semi-automatic buckle, and the lower left semi-automatic buckle move up and down along the four buckle slots respectively.

[0015] Furthermore, pressure sensors are provided at the contact portions of the upper right semi-automatic buckle, the lower right semi-automatic buckle of the connector, the upper left semi-automatic buckle of the connector, and the lower left semi-automatic buckle of the connector with the arc-shaped connector 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 this invention are:

[0017] 1. The arc-shaped semi-automatic connection structure of the detachable catamaran target vessel described in this invention reduces the difficulty of docking and improves assembly and disassembly efficiency when damaged sections need to be disassembled for repair or reassembled. Specifically, the arc-shaped protrusions on the sides of the fasteners and the rounded corners of the semi-automatic latches effectively reduce the alignment accuracy requirements of the two components in the left, right, up, and down directions, especially improving the smoothness of the docking process between sections, saving target vessel assembly and recovery time. Furthermore, the mortise and tenon structure ensures the all-around stability of the connection structure.

[0018] 2. This invention also fulfills the function of traditional semi-automatic target ship connection structures that allow for the separate disassembly and repair of damaged sections when the hull is damaged, and the installation of new sections with the same specifications for continued testing. It ensures assembly efficiency and structural strength in terms of the required precision for disassembly and assembly, structural stability, and semi-automatic connection structure.

[0019] 3. This invention optimizes the traditional cubic structure into an arc-shaped surface and the existing shell-type connection structure into a mortise and tenon connection structure. The connection relationship between the fixing parts and the connecting parts is controlled by the raising or lowering of the semi-automatic buckle, thereby completing the rapid connection between structures and the rapid repair of damaged sections, greatly reducing the difficulty of docking.

[0020] 4. Once the buckle is inserted into the buckle slot, the present invention cannot move left, right, forward, or backward. It also cannot slide up or down due to the buckle design. This invention adds additional forward and backward freedom restrictions to the four degrees of freedom, achieving six degrees of freedom omnidirectional fixation of the structure.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0028] See Figure 1-4 This embodiment describes an arc-shaped semi-automatic connection structure for a detachable catamaran target ship, comprising a fixing component and an arc-shaped connector. The upper and lower surfaces of the arc-shaped connector are provided with four snap-fit ​​grooves, and snap-fits are installed in the snap-fit ​​grooves. The snap-fits are provided with semi-arc-shaped protrusions on their sides, and can move up and down along the snap-fit ​​grooves as needed for connection. A pressure sensor 13 is provided on the back of the snap-fits. The upper and lower sides of the fixing component are provided with upper and lower top plates, and the inner sides of the upper and lower top plates are provided with upper and lower limit holes.

[0029] The present invention uses the pressure sensor 13 on the back of the semi-automatic buckle to be triggered by the upper and lower ends of the semi-automatic buckle of the connector and the upper and lower baffles of the fixing part. This controls the rise or fall of the ram's horn-shaped semi-automatic buckle on the upper and lower surfaces of the arc-shaped connector, so that the ram's horn-shaped semi-automatic buckle engages or disengages with the upper and lower limit holes provided on the upper and lower baffles of the fixing part, thereby realizing the connection or separation of the connector and the fixing part.

[0030] The semi-circular protrusions on the top plate of the fastener and the arc-shaped connector can fit linearly together, which can effectively avoid stress concentration in the structure.

[0031] In the connected state, the upper limit hole 3 of the fastener, the upper right semi-automatic buckle 6 of the connector, and the lower right semi-automatic buckle 7 of the connector adopt a tenon-and-mortise meshing, which has high stability in all six degrees of freedom.

[0032] In the connected state, the top plate 2 is tangent to the arc-shaped part of the arc-shaped connector body 5, eliminating the need for alignment precision and reducing the difficulty of docking.

[0033] The semi-automatic buckle of the arc-shaped connector is shaped like a ram's horn, and the ram's horn-shaped protrusion is a quarter-cylinder.

[0034] The four snap-fit ​​slots of the arc-shaped connector allow four ram's horn-shaped snaps to move up and down within the slots. When the ram's horn-shaped snaps descend to the bottom of the snap-fit ​​slots, the right-angled lower surface of their quarter-cylinder is exactly tangent to the upper surface of the arc-shaped connector.

[0035] The upper and lower limiting holes inside the upper and lower baffles of the fixing component can fully engage with the ram's horn-shaped semi-automatic buckles on the upper and lower surfaces of the arc-shaped connector. The upper and lower buckles of the arc-shaped connector and the upper and lower limiting holes of the fixing component form a complete fitting structure.

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

[0037] The fastener 10 includes a top plate 2, a fastener upper limit hole 3, a fastener lower limit hole 4, a fastener upper top plate 8, and a fastener lower top plate 9. The fastener upper top plate 8 and the fastener lower top plate 9 are respectively installed on the top plate 2. The fastener upper top plate 8 is provided with the fastener upper limit hole 3 on its inner side, and the fastener lower top plate 9 is provided with the fastener lower limit hole 4 at the position corresponding to the fastener upper limit hole 3 on its inner side. The two sides of the top plate 2 are the bulkhead body 1.

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

[0039] Pressure sensors 13 are provided at the contact portions of the upper right semi-automatic buckle 6, the lower right semi-automatic buckle 7, the upper left semi-automatic buckle 11, and the lower left semi-automatic buckle 12 of the connector with the arc-shaped connector body 5.

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

[0041] Meanwhile, the present invention is composed of a hull body, fasteners, and arc-shaped connectors. The fasteners and arc-shaped connectors can be connected by mortise and tenon joints. The structure utilization rate and scope of application of the invention patent with patent number CN115705784A are quite different.

[0042] Example 1: Installation

[0043] The arc-shaped semi-automatic connection structure of the detachable catamaran target ship includes a fixing component 10 and an arc-shaped connector. The main body 5 of the arc-shaped connector is provided with a semi-automatic latch 11 on the upper left, a semi-automatic latch 12 on the upper left, a semi-automatic latch 6 on the upper right, and a semi-automatic latch 7 on the upper left. A pressure sensor 13 is provided between the semi-automatic latch and the latch groove.

[0044] The upper surface 14 and lower surface 15 of the arc-shaped connector body 5 have four semi-automatic snap-fit ​​slots, of which the upper right snap-fit ​​slot 18 and the lower right snap-fit ​​slot 19 of the arc-shaped connector are examples in this embodiment.

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

[0046] The upper right snap-fit ​​groove 18 and the lower right snap-fit ​​groove 19 of the aforementioned arc-shaped connector allow the semi-automatic snap-fit ​​6 and 7 to rotate downwards and upwards along the arc surface by a small angle until the upper plane of the rounded corner of the semi-automatic snap-fit ​​is tangent to the upper surface 14 and the lower surface 15 of the main body 5 of the arc-shaped connector.

[0047] During the installation of the connector, the main bodies 10 of the two fixing parts move inward at the same time, and the front ends of the upper top plate 8 and the lower top plate 9 of the fixing parts simultaneously contact and press their respective semi-automatic buckles 6 and 7.

[0048] The pressure sensor 13 on the back of the semi-automatic buckle receives a pressure signal from the buckle slot, causing the semi-automatic buckle to rotate downwards until the rounded corner plane is tangent to the upper and lower surfaces 14 and 15 of the arc-shaped connecting body 5. At this time, the rounded lower tangent of the semi-automatic buckle is in contact with 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 their front ends come into contact with each other. At this time, the top plate 2 just comes into contact with the arc-shaped protruding arc surface 20 of the arc-shaped connecting body 5. When the top plate 2 and the arc-shaped protruding arc surface 20 are in complete linear contact, the semi-automatic buckles 6 and 7 pop up. At this time, the semi-automatic buckles 6 and 7 engage 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 face 23 of the semi-automatic buckles 6 and 7 presses against the upper and lower limit holes 3 and 4 of the upper top plate 8 and lower top plate 9, so that the main body of the arc-shaped connector is firmly fixed.

[0051] After the arc-shaped connector is fixed, during the process until the front ends of the upper top plate 8 and the lower top plate 9 come into contact, the square surface 23 of the semi-automatic buckles 6 and 7 can abut against the upper and lower limit holes of the upper top plate 8 and the lower top plate 9, which can ensure that the fixing parts 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 latches 6 and 7 are fully engaged in 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 two side compartments do not slide vertically, thus achieving complete restriction in six degrees of freedom.

[0053] Example 2: Disassembly

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

[0055] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
