Description

Technical Field

[0001] This invention belongs to the field of underwater acoustics and relates to a device for threading the core sheath of an underwater acoustic linear array that can be applied to different sheath diameters and lengths. Background Technology

[0002] In recent years, with the increasingly prominent economic and military status of the ocean, the level of marine exploration technology has been developing rapidly. Underwater acoustic signal analysis is the most basic and effective technical means in marine exploration activities, and linear array is the most commonly used acoustic signal receiving equipment in underwater acoustic signal analysis. It has been widely used in modern anti-submarine warfare, underwater defense, resource exploration, marine monitoring, marine experiments, ship navigation, shore-based counter-terrorism, underwater target search, and so on.

[0003] A linear array is an underwater acoustic signal acquisition device composed of several hydrophone units arranged at predetermined intervals. Its length can range from several meters to several kilometers, depending on the number of array elements and testing requirements. For long linear arrays with multiple elements of different sheath diameters and lengths, the structure is large and complex, and the signal transmission distance of the hydrophone units is relatively long. Therefore, an amplifier circuit is usually connected at the front end of the hydrophone to amplify the received underwater acoustic signal before transmission, ensuring the quality of the received signal at the dry end. The amplifier circuit requires DC power, making the power supply system a key technical aspect for ensuring the normal operation of the linear array. To obtain higher spatial gain and more precise and accurate test results, the number and length of array elements in long linear arrays are constantly increasing. The element sizes of long linear arrays vary depending on the specific requirements. These components, as the main components of the long linear array core, also determine the different diameters of the sheath tubes. In this case, a long linear array sheath tube insertion device is necessary to insert array cores of different diameters and lengths into the long linear array sheath tubes. Therefore, how to quickly, efficiently, and reliably insert the core of the long linear array into the sheath tube of the long linear array has become a key problem that must be solved. Summary of the Invention

[0004] The technical problem to be solved

[0005] This invention provides a long linear array sheathing tube insertion device, offering a more convenient and faster method for inserting underwater acoustic long linear array cores of different diameters and lengths into the sheathing tube. This solves the problem of inserting long linear array cores into the sheathing tube.

[0006] Technical solution

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] A long linear array sheathing pipe threading device comprises: two 1-ton tension winches, two fixing frames, bolts, steel wire ropes, steel wire rope locks, support bases, stainless steel pipe clamps, rubber U-shaped clips, three fixed pulleys, and PU sheathing pipes. The two fixing frames are bolted to load-bearing walls spaced 100 meters apart, ensuring they are aligned in a straight line. The two winches are then welded to the fixing frames, again ensuring they are in a straight line. Each winch contains a 220-meter-long steel wire rope.

[0009] During assembly, the fixed pulleys at both ends of the fixed bracket are secured with bolts. The left fixed pulley is positioned 20 cm above the winch, and a ground pulley parallel to the ground is fixed above it. The right fixed pulley is also positioned 20 cm above the winch. Its function is to allow the wire rope released from the right winch to be stretched through the fixed pulleys, then through the parallel fixed pulley on the left fixed bracket, and finally return to the fixed position at the right winch end for securing. The right winch then tightens the wire rope, forming an O-shaped loop, which secures the support base. The support base has holes on both sides for securing wire rope locks. The support base is secured to two wire ropes every 0.5 meters using the locks, ensuring they are perpendicular to the ropes and parallel to each other. The stainless steel clamp bracket is fixed to the support base using slots, and then rubber U-shaped clips are fixed into the stainless steel clamp bracket. Locking bolts are then placed in the bolt holes of the stainless steel clamp bracket.

[0010] When using, place the PU sheath tube into the rubber U-shaped buckle from left to right to make the PU sheath tube straight. Then, use the locking bolt to lock the stainless steel clamp bracket, so that the rubber U-shaped buckle completely fixes the PU sheath tube above the bracket base. Pass the unused wire rope from the winch on the other end through the PU sheath tube and fix it to the long line array core. Use the tension of the wire rope recovered by the winch to slowly pull the array core into the PU sheath tube, thereby realizing the function of guiding the long line array core into the sheath tube.

[0011] The beneficial effects of this invention are: a long linear array sheath threading device has a simple and reliable structure, can be assembled and disassembled at any time, is flexible in use, has low cost, is suitable for threading underwater acoustic linear array core sheaths of different sheath diameters and lengths, saves manpower and improves work efficiency. Attached Figure Description

[0012] Figure 1 This is a top view of the present invention.

[0013] Figure 2 This is a side view of the present invention.

[0014] The components include: two winches (1 and 13), locking bolts (2), rubber U-shaped clips (3), wire rope locks (4), two sets of wire ropes (5 and 8), two fixed pulleys (6, 11 and 15), two sets of fixed frames (7 and 12), stainless steel clamp brackets (9), PU sheathing tubes (10), and bracket bases (14). Detailed Implementation

[0015] The present invention will now be described in conjunction with embodiments.

[0016] A long linear array sheathing pipe threading device comprises: 1-ton pulling winches 1 and 13, fixing frames 7 and 12, locking bolts 2, steel wire ropes 5 and 8, steel wire rope locks 4, support base 14, stainless steel pipe clamp brackets 9, rubber U-shaped buckles 3, fixed pulleys 6, 11, and 15, and PU sheathing pipe 10, etc. The two fixing frames at both ends are fixed to load-bearing walls spaced 100 meters apart by bolts, ensuring that the two fixing frames 7 are on the same straight line. The two winches 1 and 13 are fixed to the two fixing frames 7 and 12 at both ends by electric welding, again ensuring that the winches 1 and 13 are on the same straight line. Each winch 1 and 13 has a 220-meter-long steel wire rope wound inside.

[0017] During assembly, the fixed pulleys 6, 11, and 15 are secured to the upper positions of the two end fixing brackets 7 and 12 with bolts. The left fixed pulley 15 is positioned 20 cm above the winch, and a fixed pulley 6 parallel to the ground is fixed above it. The right fixed pulley 11 is also positioned 20 cm above the winch. Its function is to allow the wire rope 5 released from the right winch 13 to be stretched through the fixed pulley 11, then through the parallel fixed pulley 6 on the left fixing bracket 7, and finally return to the fixed position of the right winch 13 for fixation. The right winch 13 then tightens the wire rope 5, forming an O-shaped loop, which serves to fix the support base 14. The support base 14 has holes on both sides for fixing wire rope locks 4. The support base 14 is fixed to two wire ropes 5 with wire rope locks 4, one every 0.5 meters, and is made perpendicular to the wire ropes 5, with each support base 14 parallel to each other. The stainless steel pipe clamp bracket 9 is fixed to the bracket base 14 by a slot, and then the rubber U-shaped buckle 3 is fixed in the stainless steel pipe clamp bracket 9, and the locking bolt 2 is placed in the bolt hole of the stainless steel pipe clamp bracket 9.

[0018] In use, place the PU sheath tube 10 into the rubber U-shaped buckle 3 from left to right, so that the PU sheath tube 10 is in a straight line. Then, use the locking bolt 2 to lock the stainless steel clamp bracket 9, so that the rubber U-shaped buckle 3 completely fixes the PU sheath tube 10 above the bracket base 14. Pass the unused wire rope 8 on the other end of the winch 1 through the PU sheath tube 10 and fix it to the long line array core. By using the tension of the wire rope recovered by the winch 1, the array core is slowly pulled into the PU sheath tube 10, thereby realizing the function of the long line array core being inserted into the sheath tube.
