[0035] The working principle of this easy-to-install protective marine dynamic cable will be explained in detail below.
[0036] like Figure 1 - Figure 10 As shown, in use, firstly, the S-shaped docking plate 13 and S-shaped docking plate 2 14 included in the scissor locking plate assembly 6 are docked with the umbilical cable 1 at the position where it needs to be fixed. At this time, the opening positions of S-shaped docking plate 13 and S-shaped docking plate 2 14 are aligned with each other, forming the shape of the number "8". Then, S-shaped docking plate 13 and S-shaped docking plate 2 14 are rotated around the shaft 15 in a direction away from each other, so that the top is fitted onto the outer wall of the umbilical cable 1, maintaining the fitted state. At this time, the umbilical cable 1 is equivalent to being inserted into the ring at the top of the number "8". Then, the collar formed at the bottom of S-shaped docking plate 13 and S-shaped docking plate 2 14 can be docked with the built-in insertion tube 12 on the trapezoidal receiving base 4. One end of the built-in insertion tube 12 is fixed on the trapezoidal receiving base 4, and the other end is suspended in the air, and the whole is parallel to the bottom surface of the trapezoidal receiving base 4.
[0037] After the bottom annular structures of S-shaped docking plates 13 and 14 are fitted onto the internal insertion tube 12, a receiving arc plate 11 is fixed to the inner wall of the trapezoidal receiving base 4 below the internal insertion tube 12. The top of the trapezoidal receiving base 4 has a groove that matches the receiving arc plate 11. The receiving arc plate 11 restricts the annular structures at the bottom of S-shaped docking plates 13 and 14, preventing them from rotating and opening. Consequently, the annular structures at the top of both plates, which are fitted onto the outer wall of the umbilical cable 1, also cannot open. This completes the connection between the umbilical cable 1 and the trapezoidal receiving base 4.
[0038] Then, the side sealing block 5 is connected to one end of the trapezoidal receiving base 4. A disc structure is fixed on the top of the side sealing block 5. A limiting ring 17 is fixedly connected to the side of the disc structure near the internal insertion tube 12, and a side insertion rod 16 is fixed in the center of the disc structure. The side insertion rod 16 will be inserted into the inner wall of the internal insertion tube 12, and the limiting ring 17 will be sleeved on the outer wall of the internal insertion tube 12 to fill the gap between the internal insertion tube 12 and the receiving arc plate 11, ensuring the structural firmness of the internal insertion tube 12.
[0039] Two symmetrical side position insertion plates 10 are fixed on the side surface of the side position closing block 5 near the bottom end. The trapezoidal receiving base 4 is provided with a horizontal insertion slot 9 corresponding to the side position closing block 5 near one end of the side position closing block 5. After the side position closing block 5 is connected to the trapezoidal receiving base 4, the side position insertion plate 10 is inserted into the horizontal insertion slot 9. The side inclined surface of the trapezoidal receiving base 4 is provided with a right-angle slot, which is communicated with the horizontal insertion slot 9. The inner wall bottom of the right-angle slot and the side position insertion plate 10 are both provided with a base insertion hole 8. After the side position insertion plate 10 is connected to the trapezoidal receiving base 4, the seabed anchor rod 7 is sequentially inserted into the base insertion hole 8 of the side position insertion plate 10 and the base insertion hole 8 of the trapezoidal receiving base 4 and is anchored into the seabed. In this way, the umbilical cable 1 can be fixed.
[0040] After the shear type locking plate group 6 is sleeved on the umbilical cable 1 and the built-in insertion tube 12, the annular structure at the bottom end of the S-shaped butt joint plate one 13 and the S-shaped butt joint plate two 14 can rotate 0-10° around the built-in insertion tube 12, avoiding rigid fixation of the umbilical cable 1. When the umbilical cable 1 is shaken by seawater impact, excessive wear and tear of the umbilical cable 1 shell is avoided. After the installation assembly 2 fixes the umbilical cable 1, the two sets of arc-shaped clamping plates 20 included in the protection assembly 3 are symmetrically sleeved on the outer wall of the umbilical cable 1. At this time, the arc-shaped clamping plates 20 can be placed at one end of the installation assembly 2. Then, one end of the arc-shaped clamping plate 20 is locked by the locking ring hoop 21. The inner wall of the locking ring hoop 21 is fixed with an inner built-in arc-shaped strip 36 corresponding to the clamping limiting arc-shaped slot 35.
[0041] When one end of the two sets of arc-shaped clamping plates 20 is fixed, the wing type damping member one 18 and the wing type damping member two 19 included in the protection assembly 3 are sequentially installed on the arc-shaped clamping plate 20. The two ends of the wing type damping member two 19 are symmetrically distributed with the wing type damping member one 18. The wing type damping member one 18 includes wing type block one 22 and wing type block two 23 symmetrically distributed with the center axis of the umbilical cable 1. The wing type block one 22 and the wing type block two 23 both present a C-shaped structure. The inner wall of the wing type block two 23 is fixedly connected with an inner built-in arc-shaped block two 25. The inner wall of the wing type block one 22 is fixedly connected with an inner built-in arc-shaped block one 24. One end of the inner built-in arc-shaped block two 25 is fixed with an extension arc-shaped plate one 26, and the other end is fixed with an extension arc-shaped plate two 27. The wing type block one 22 and the wing type block two 23 have the same structure. Therefore, after the wing type block one 22 and the wing type block two 23 are connected, the extension arc-shaped plate two 27 on the inner wall of the wing type block one 22 is attached to the outer wall of the extension arc-shaped plate one 26 on the wing type block two 23, and the extension arc-shaped plate one 26 on the wing type block one 22 is attached to the inner wall of the extension arc-shaped plate two 27 on the wing type block two 23.
[0042] The built-in arc block one 24 and the built-in arc block two 25, together with the corresponding extended arc plate one 26 and the extended arc plate two 27, form a double-layered structure similar to a ring, which is wrapped around the outer wall of the arc-shaped clamping plate 20. Moreover, the outer wall of the extended arc plate one 26 on the built-in arc block two 25 is installed with the outer permanent magnet strip 28, and the inner wall of the extended arc plate two 27 is installed with the inner permanent magnet strip 29. The extended arc plate one 26 on the built-in arc block one 24 is also installed with the outer permanent magnet strip 28 and the inner permanent magnet strip 29, which are distributed in a staggered manner with the built-in arc block two 25.
[0043] Therefore, when the wing-shaped blocks one 22 and two 23 are impacted by seawater, due to the similar NACA airfoil shape, the bottom of the wing-shaped block one 22 has a large flow rate and a small pressure, and the top has a relatively increased pressure, which drives the built-in arc block one 24 to rotate around the outer wall of the extended arc plate one 26 and the inner wall of the extended arc plate two 27. During the rotation, the repulsive force between the two groups of outer permanent magnet strips 28 and inner permanent magnet strips 29 counteracts the impact of seawater. At the same time, the bottom arc surface of the wing-shaped block one 22 is provided with a flow guide groove 32, the inner wall of which is provided with two lateral drainage holes 33, and the upper arc surface of the wing-shaped block one 22 is provided with a receiving groove 34. The arrangement of the wing-shaped damping members one 18, two 19, and one 18 is from left to right.
[0044] The lateral drainage holes 33 on the wing-shaped damping member two 19 are in communication with the receiving grooves 34 on the wing-shaped damping member one 18. Therefore, when seawater impacts, the upper arc surface of the wing-shaped damping member two 19, which meets seawater, has a large flow rate, while the upper arc surface of the wing-shaped damping member one 18 has a reduced flow rate due to the obstruction of the receiving grooves 34. Seawater also flows into the receiving grooves 34 through the lateral drainage holes 33, thereby disturbing the flow direction of the impacting seawater and reducing the impact force. When the wing-shaped damping member one 18 and the wing-shaped damping member two 19 are end-to-end connected, the side arc grooves 30 on one end of the built-in arc block one 24 and the built-in arc block two 25, and the fixed side arc blocks 31 on the other end, are inserted, which ensures that the wing-shaped damping member one 18 and the wing-shaped damping member two 19 can be stably connected when they are connected.
[0045] The side arc-shaped block 31 can move in the inner wall of the side arc-shaped groove 30, and will not affect the relative rotation of the built-in arc-shaped block one 24 and the built-in arc-shaped block two 25. When the built-in arc-shaped block one 24 and the built-in arc-shaped block two 25 are installed on the arc-shaped clamping plate 20, the built-in arc-shaped block one 24 and the built-in arc-shaped block two 25 are misaligned and then combined with each other to form a ring structure sleeved on the outer wall of the arc-shaped clamping plate 20. Then the other end of the arc-shaped clamping plate 20 is fixed by the locking ring 21. After the installation assembly 2 and the protection assembly 3 are installed, when multiple groups of installation assemblies 2 and protection assemblies 3 are installed, the installation assemblies 2 and the protection assemblies 3 are installed alternately along the umbilical cable 1. In this way, the stability of the installation of the umbilical cable 1 is ensured, and the impact of seawater on the umbilical cable 1 is reduced. At the same time, the protection assembly 3 can protect the outer wall of the umbilical cable 1.
