Description

Technical Field

[0001] This invention belongs to the field of conventional weapon combat automation, specifically relating to a signal connection device and wiring method for a naval gun electrical system. Background Technology

[0002] like Figure 10 As shown, the equipment required for the ship's gun electrical system includes under-gun equipment and on-gun equipment;

[0003] The equipment under the gun is fixed to the floor, including the gun control cabinet, servo drive cabinet, firing drive cabinet, and servo power supply cabinet. The equipment on the gun is fixed to the gun, including the azimuth / elevation angle limiter, the combined analysis box (including the synchro and cam), the navigation restraint, the fire control valve, the azimuth / elevation motor, and the fire control motor. Currently, the on-gun and under-gun equipment are connected by direct cable connection, which has the following drawbacks:

[0004] 1. The plugs, sockets, and cables of the gun-mounted equipment are easily damaged during operation. The total weight of the cables directly connecting the gun-mounted and unmounted equipment exceeds 150KG. At this weight, the tensile force generated by the cables is directly applied to the plugs or sockets of the gun-mounted equipment, which can easily cause damage to the stressed plugs or sockets. When the gun moves in azimuth or elevation, the gun will move synchronously with the gun-mounted equipment, which will further increase the tensile force of the cables on the gun-mounted equipment, making it even easier to damage the plugs, sockets, and cables of the gun-mounted equipment.

[0005] 2. There is a lack of a device for recombining the core wires of the gun-mounted cables and the gun-mounted cables. Taking gun position information as an example, the gun position information fed back by the synchro in the gun-mounted equipment's analysis box is transmitted through two gun-mounted cables. One cable contains two azimuth position information channels: azimuth channel A and azimuth channel B; the other cable contains two elevation position information channels: elevation channel A and elevation channel B. However, the gun position information required by the gun-mounted equipment is transmitted through two gun-mounted cables: one containing azimuth and elevation channel A, and the other containing azimuth and elevation channel B. Since the core wire contents of the gun-mounted and gun-mounted cables are different, the core wires of the cables need to be recombined for use by the gun-mounted equipment.

[0006] 3. Troubleshooting cable faults is time-consuming and difficult. Because the cables connecting the gun's equipment and the equipment below the gun are subject to tension from movement, they frequently fail. Therefore, these cables are a crucial point to check when troubleshooting the gun's electrical system. However, checking the cables requires disassembling them, increasing the time and difficulty of the investigation and causing significant inconvenience.

[0007] Therefore, it is essential to design a signal swivel device and wiring method for the ship's gun electrical system. Summary of the Invention

[0008] The purpose of this invention is to solve the problems of existing technologies, such as cables being easily pulled, cables being difficult to assemble, and cables being difficult to inspect. To this end, an electrical signal swivel device and wiring method for naval guns are provided.

[0009] To achieve the above objectives, the technical solution provided by this invention is:

[0010] A signal coupling device for a naval gun electrical system, characterized in that...

[0011] Includes swivel brackets and signal adapter boxes;

[0012] The rotating bracket is located below the gun bed and is coaxial with the gun's rotation axis.

[0013] The signal adapter box includes a box body, multiple support frames, and multiple wiring devices;

[0014] The enclosure is a cuboid; the top and bottom surfaces of the enclosure are provided with multiple inlet holes and multiple outlet holes; the front of the enclosure is a removable cover, and the inner side of the back of the enclosure is provided with multiple support bracket mounting holes; the back of the enclosure is mounted on a rotating bracket.

[0015] The multiple support frames are fixedly connected in parallel to the inner side of the back of the housing; the wiring device is fastened to the support frame and is used to connect the gun upper cable and the gun lower cable; the gun upper cable and the gun lower cable pass through the inlet hole and the outlet hole respectively and are installed on the wiring device.

[0016] Furthermore,

[0017] The wiring device includes a terminal block, bolts, nuts, fastening screws, a longitudinal terminal block, and a transverse terminal block;

[0018] The terminal block is elongated and has two rows of first threaded through holes along its length, and second threaded through holes at both ends; the bottom end of the terminal block has a groove.

[0019] The bolt is a second-order shaft bolt with a threaded head and a cylindrical tail. The bolt is installed in the first threaded through hole of the terminal block with its tail pointing towards the box cover. The bolt head height is less than the groove depth. The cylinder is a terminal block, and the top of the cylinder does not contact the box cover.

[0020] The longitudinal terminal block is a thin metal plate, and the longitudinal terminal block is provided with two first through holes. The size and relative position of the two first through holes are matched with the first threaded through holes in the same row of two columns of first threaded through holes. The longitudinal terminal block passes through two bolts and is pressed into the top surface of the terminal block by two nuts.

[0021] The horizontal terminal block is a thin plate, and its shape matches that of the terminal block. It has second through holes at both ends. The horizontal terminal block is placed on the bottom surface of the terminal block and seals the groove. The fastening screws pass through the second threaded through hole and the second through hole in sequence to fasten the horizontal terminal block and the terminal block to the support frame.

[0022] Furthermore,

[0023] The rotating support adopts a basket; the basket has a prism frame structure, and the center of the top surface and the center of the bottom surface of the basket are provided with a central through hole coaxial with the rotating shaft of the ship gun; a wire-laying post is provided between the hole wall of the central through hole on the bottom surface of the basket and the bottom edge of the basket; a mounting platform is provided at each of the four corners of the side of the basket, and the four corners of the back of the signal adapter box are provided with box mounting holes; the four mounting platforms cooperate with the four box mounting holes to fix the signal adapter box to one side surface of the basket.

[0024] A wiring method for using the aforementioned signal swivel device of the naval gun electrical system is characterized by the following steps:

[0025] Step 1: Expose the core wire of the cannon's cable at one end of the signal adapter box;

[0026] Step 2: Pass the gun cable through the signal adapter box inlet hole and install the core wire on a row of terminals;

[0027] Step 3: Connect the other end of the gun cable to the gun equipment;

[0028] Step 4: Expose the core wire at one end of the cable signal adapter box under the blaster;

[0029] Step 5: Pass one end of the cable under the blaster through the center hole on the bottom of the cradle, place it on the cable tie post of the cradle, then pass it through the outlet hole of the signal transfer box, and install the core wire on another row of terminals.

[0030] Step 6: Connect the other end of the under-barrel cable to the under-barrel equipment.

[0031] The concept of this invention:

[0032] To address the shortcomings of existing technologies, a signal coupling device for a naval gun electrical system was designed, comprising a hopper and a signal junction box; wherein, for example... Figure 1 As shown, the suspended platform 8 bears the weight of the cable through the cable tie posts 10, and also bears the tensile force exerted by the cable on the plug and socket due to gravity. Due to limited space below the naval gun, it needs to be installed on one side of the suspended platform 8, and multiple cables are centrally connected and branched within a signal transfer box with a maximum space of 690mm×550mm×1600mm (length×width×height). Therefore, the following design was implemented... Figure 2The signal junction box shown improves overall space utilization by centrally arranging multiple sets of terminals to centralize the wiring, switching, and branching functions of cables.

[0033] The advantages of this invention are:

[0034] 1. This method hangs the gun's under-gun cable on the cable tray's connecting post, reducing the pulling force on the cable; this equipment installs the signal transfer box on the tray, placing the signal transfer box close to the gun's rotation axis, reducing the cable's rotation radius, further reducing the pulling force on the cable, and improving the reliability of the entire gun's electrical system.

[0035] 2. This equipment utilizes the internal space of the naval gun to centrally arrange multiple sets of terminal blocks, centralizing the connection, transfer and branching functions of cables. It has a compact structure and improves the overall space utilization rate.

[0036] 3. During testing, this equipment only requires opening the cover of the signal adapter box and directly measuring the longitudinal terminal block and terminals with measuring instruments. It can quickly measure cable faults without disassembling the cable, thus improving the efficiency of fault diagnosis and repair. Attached Figure Description

Detailed Implementation

[0048] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. These embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0049] like Figures 1-9 A signal coupling device for a naval gun electrical system, comprising a basket and a signal transfer box;

[0050] like Figure 1 The basket 8 shown is a prismatic frame structure. In this embodiment, a pentagonal prismatic frame structure is used, and the prismatic surfaces are all hollow structures for weight reduction. The center of the top surface and the center of the bottom surface of the basket 8 are provided with a central through hole coaxial with the rotating axis of the ship gun. A cable-laying post 10 is provided between the hole wall of the central through hole on the bottom surface of the basket 8 and the bottom edge of the basket 8 for connecting cables, bearing the weight of the cables, and preventing the ship gun from excessively pulling the cables and signal conversion box during operation. The basket 8 is set below the gun bed of the ship gun and is coaxial with the rotating axis of the ship gun. When the ship gun moves in the azimuth or elevation direction, it drives the basket 8 to move synchronously. There is a mounting platform 9 at each of the four corners of the side of the basket. The four mounting platforms 9 cooperate with the four box mounting holes. The signal conversion box is fixed to the side surface of the basket by screws.

[0051] like Figure 2 , Figure 3 As shown, the signal adapter box includes a housing 1, multiple support frames 2, and multiple six-pin terminal blocks 3;

[0052] like Figure 4 As shown, the enclosure 1 is a cuboid. The top and bottom surfaces of enclosure 1 have multiple inlet and outlet holes. The inner side of the back of enclosure 1 has multiple support bracket mounting holes 11. The four corners of the back of enclosure 1 have mounting holes that mate with four mounting platforms 9. The front of enclosure 1 is a removable cover. Figure 5 As shown, the support frame 2 is long and narrow, with two support plate mounting holes at both ends; "L"-shaped mounting plates extend downward from both ends of the support frame 2 to ensure sufficient operating space below the support frame; the bottom surface of the "L"-shaped mounting plate is provided with a third threaded through hole 14, and the third threaded through hole 14 cooperates with the support frame mounting hole 11; multiple support frames 2 are fixedly connected in parallel to the inner side of the back of the box by screws.

[0053] like Figure 6 As shown, in this embodiment, the wiring device is a six-post terminal block 3, which includes a terminal block 4, bolts 5, nuts, fastening screws, a longitudinal terminal block 6, and a transverse terminal block 7. The six-post terminal block 3 is fastened to the top surface of the support frame 2, and the distance from the six-post terminal block to the side wall of the box is not less than 30mm.

[0054] The terminal block 4 is long and has two rows of first threaded through holes 12 along its length, with a total of six first threaded through holes 12 in each row; the terminal block 4 has second threaded through holes 13 at both ends; the bottom end of the terminal block 4 has a groove, the length of which is greater than the longest length of a row of bolt heads installed on the terminal block, and the depth of which is greater than the height of the bolt heads.

[0055] like Figure 7 As shown, the bolt is a second-order shaft bolt with a long threaded head and a short cylindrical tail. The bolt is installed in the first threaded through hole 12 of the terminal block and the tail points towards the box cover. The cylindrical tail is the terminal block, and the adapter cable is connected to the terminal block to facilitate the installation and removal of the adapter cable, prevent the threads from scratching the cable, and ensure that the top of the cylindrical tail does not contact the box cover to avoid short circuit.

[0056] like Figure 8 As shown, the longitudinal terminal block 6 is a thin metal plate used for signal transfer between two adjacent terminals; the longitudinal terminal block 6 is provided with two first through holes 15, the size and relative position of the two first through holes 15 are matched with the same row of first threaded through holes 12 in the two columns; the longitudinal terminal block 6 passes through two bolts and is pressed onto the top surface of the terminal block 4 by two nuts;

[0057] like Figure 9 As shown, the horizontal terminal block 7 is an insulating bakelite sheet with second through holes 16 at both ends, and its shape matches that of the terminal block 4. The horizontal terminal block 7 is installed on the bottom surface of the terminal block 4 and seals the groove to prevent the bolt 5 from contacting the support frame 2 and conducting electricity, thus providing insulation. The fastening screws pass through the second threaded through hole 13 and the second through hole 16 in sequence to fasten the horizontal terminal block 7 and the terminal block 4 to the support frame.

[0058] The wiring method for the signal swivel equipment of the ship's gun electrical system is as follows:

[0059] Step 1: Strip the outer sheath of the cable on the cannon at one end of the signal adapter box to expose the core wire;

[0060] Step 2: Pass the cable on the gun through the center through hole above the basket and the inlet hole of the signal transfer box, and install the core wire on a row of terminals;

[0061] Step 3: Connect the other end of the gun cable to the gun equipment;

[0062] Step 4: Strip the outer sheath of the cable under the cannon at one end of the signal adapter box to expose the core wire;

[0063] Step 5: Pass one end of the cable under the cannon through the central through hole at the bottom of the basket 8, hang it on the connecting post 10 of the basket 8, and then pass it through the outlet hole of the signal transfer box to install the core wire on another row of terminals.

[0064] Step 6: Connect the other end of the under-barrel cable to the under-barrel equipment.

[0065] By using the above wiring method, the gun's cable is hung on the connecting post 10 of the cradle 8, which bears the weight of the cable and reduces the pulling force on the plug and socket. As the gun rotates, the cradle 8 rotates, which in turn drives the signal transfer box to rotate. The cable inside the signal transfer box is approximately parallel to and close to the gun's rotation axis, reducing the cable's rotation radius and further reducing the pulling force on the cable, thus improving the reliability of the entire gun's electrical system.

[0066] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the scope of the technology disclosed in the present invention, and such modifications or substitutions should all be covered within the scope of protection of the present invention.
