[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figures 1 to 6 , the dynamic submarine cable auxiliary device and shallow water floating photovoltaic system provided by the embodiments of the present invention are described in detail through specific embodiments and their application scenarios.

[0026] First, as Figure 1 As shown, this embodiment provides a dynamic submarine cable auxiliary device 1, including: a body 11, a clamp 12, a buoyancy chamber 13, a propulsion assembly 14 and a mooring assembly 15.

[0027] The body 11 has a hollow inner cavity, and the buoyancy chamber 13 is arranged in the inner cavity of the body 11 so that the body 11 floats on the sea surface; the mooring component 15 is arranged at the bottom of the body 11, and the mooring component 15 is used to moor and position the body 11.

[0028] The clamp 12 is disposed at the top of the body 11 and is used to clamp the dynamic submarine cable 2. The propulsion assembly 14 is installed on the body 11 and is used to propel the body 11 to the installation position and drive the dynamic submarine cable 2 to form a preset line shape.

[0029] It can be understood that the density of the buoyancy chamber 13 is less than the density of seawater. The buoyancy chamber 13 provides buoyancy to the dynamic submarine cable 2. One end of the mooring component 15 is connected to the main body 11, and the other end of the mooring component 15 is fixedly connected to the seabed. The mooring component 15 provides pulling force to the dynamic submarine cable 2. The combined action of the buoyancy chamber 13 and the mooring component 15 on the dynamic submarine cable 2 constructs the dynamic submarine cable 2 into an S-shaped line floating on the sea surface. When the sea surface environment is relatively harsh, the deformation of the crests and troughs constructed by the S-shape can alleviate the tension on the dynamic submarine cable 2, so that the dynamic submarine cable 2 maintains stability.

[0030] The clamp 12 of this embodiment is used to fix the dynamic submarine cable 2, and clamps the dynamic submarine cable 2 on the main body 11, so that the dynamic submarine cable auxiliary device 1 can apply force to the dynamic submarine cable 2. Specifically, the clamp 12 can use two clamping heads to clamp the dynamic submarine cable 2 together, or a cylindrical clamping head sleeve can be set on the dynamic submarine cable 2.

[0031] Specifically, the main body 11 of the present embodiment is a rectangular parallelepiped structure with a hollow inner cavity. The buoyancy chamber 13 is also a rectangular parallelepiped structure. The volume of the buoyancy chamber 13 is smaller than the volume of the main body 11. Two buoyancy chambers 13 are installed in the inner cavity of each main body 11. The two buoyancy chambers 13 are arranged at intervals and are arranged at both ends of the inner cavity.

[0032] There are multiple dynamic submarine cable auxiliary devices 1, and the multiple auxiliary devices 1 are arranged at intervals along the axial direction of the dynamic submarine cable 2 to construct the dynamic submarine cable 2 into a preset line shape.

[0033] The propulsion assembly 14 can apply a propulsion force to the main body 11. When the dynamic submarine cable 2 is installed, the propulsion assembly 14 can push the main body 11 to move along the extension direction of the dynamic submarine cable 2 until the main body 11 moves to a preset installation position. At this time, multiple auxiliary devices 1 are arranged at intervals on the dynamic submarine cable 2, and the dynamic submarine cable 2 is arranged in a straight line. Then, the propulsion assembly 14 can also drive the dynamic submarine cable 2 to move radially along the dynamic submarine cable 2 to construct a preset line shape, so that the dynamic submarine cable 2 is arranged in an S shape, so as to achieve the purpose of quickly and effectively constructing a preset linear shape.

[0034] Specifically, the propulsion assembly 14 may be propulsive by blades or by water jets.

[0035] The dynamic submarine cable auxiliary device 1 provided by the present invention is provided with a clamp 12, a buoyancy chamber 13, a propulsion assembly 14 and a mooring assembly 15 on a main body 11, and the clamp 12 is used to fix and clamp the dynamic submarine cable 2, the buoyancy chamber 13 provides buoyancy to the dynamic submarine cable 2, and the mooring assembly 15 provides pulling force to the dynamic submarine cable 2. When the dynamic submarine cable 2 is installed and constructed, the propulsion assembly 14 is used to push the main body 11 to move along the axial direction of the dynamic submarine cable 2, so that a plurality of main bodies 11 are arranged at intervals along the axis. The propulsion assembly 14 can also drive the dynamic submarine cable 2 to move radially, so that the dynamic submarine cable 2 constructs an S-shaped preset linear shape. Based on the control of the direction and speed of the propulsion assembly 14, the movement of the main body 11 along the preset path is realized, so that the main body 11 can be installed quickly and effectively relative to the dynamic submarine cable 2. Without repeated manual adjustment, the dynamic submarine cable 2 can be automatically installed, thereby improving the installation efficiency of the dynamic submarine cable 2, reducing the construction cost, and shortening the installation time.

[0036] In some embodiments, Figure 1 As shown, the propulsion assembly 14 of this embodiment includes a water jet propulsion device 141 and a rotating platform 142 .

[0037] The rotating platform 142 is rotatably mounted on the bottom of the body 11 , and the water jet propulsion device 141 is disposed on the rotating platform 142 .

[0038] It can be understood that the water jet propulsion device 141 is a propeller that uses the reaction force generated by the jet water flow to propel the main body 11 forward. It uses a water pump to suck in water and then sprays the water at high speed through a nozzle to generate thrust to propel the main body 11 forward. The water jet propulsion device 141 has high efficiency, excellent steering performance, safety and durability, and can accurately propel the main body 11 forward along a preset path.

[0039] Since the water jet propeller 141 can only spray water toward its rear, the rotating platform 142 of this embodiment can adjust the water spraying direction of the water jet propeller 141, so that when constructing an S-shaped line, the water spraying direction of each water jet propeller 141 is required to be different. The water spraying direction of each water jet propeller 141 can be adjusted by simply controlling the rotating platform 142 to rotate at a preset angle.

[0040] Specifically, in this embodiment, a rotary driver can be provided to drive the rotation of the rotating table 142. The rotary driver is provided on the main body 11, and the rotary driver is transmission-connected to the rotating table 142. A controller can also be provided on the main body 11, and the controller is electrically connected to the rotary driver. The controller is communication-connected to the master control platform. The master control platform feeds back control information to each controller. The controller controls the rotary driver to drive the rotating table 142 to rotate to a preset angle, thereby realizing the adjustment of the water spraying angle and water spraying amount of each water jet propulsion device 141.

[0041] In some embodiments, Figure 1 As shown, the dynamic submarine cable auxiliary device 1 of this embodiment further includes: a damping component 16.

[0042] The damping assembly 16 is disposed on the body 11 , and is used to increase the motion damping of the body 11 to reduce the swaying of the dynamic submarine cable 2 .

[0043] It is understandable that the damping component 16 can absorb and consume the energy of waves, thereby reducing the vibration of the wave on the main body 11, so as to reduce the swaying of the wave on the dynamic submarine cable 2, thereby reducing the structural fatigue of the dynamic submarine cable 2 and increasing the service life of the dynamic submarine cable 2. In addition, the damping component 16 can enable the main body 11 to reach a new stable state more quickly under the impact of waves, and prevent the main body 11 from continuing to oscillate after receiving a disturbance and causing the dynamic submarine cable 2 to continue to oscillate. Based on the absorption of the impact energy of the wave by the damping component 16, the main body 11 can also be protected from damage, thereby ensuring the reliable use of the main body 11.

[0044] Specifically, the damping component 16 may absorb the energy of the waves by using inclined multi-layer perforated plates, or may use viscoelastic materials to absorb the energy of the waves.

[0045] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, the damping assembly 16 of this embodiment includes: a frame 161 , a damping plate 162 and a fixing rod 163 .

[0046] The frame 161 is sleeved on the body 11 , and the frame 161 is connected to the body 11 via a fixing rod 163 .

[0047] The damping plate 162 is covered on the frame 161 and is a mesh structure.

[0048] It can be understood that the frame 161 of this embodiment is a rectangular three-dimensional structure, and the frame 161 is mounted on the outside of the main body 11. When the main body 11 and the frame 161 are both rectangular structures, the frame 161 of this embodiment corresponds to six damping plates 162, and the six damping plates 162 are arranged on the six sides of the frame 161 to form a full-dimensional damping protection for the six sides of the main body 11.

[0049] The mesh structure has multiple pores. When waves pass through the mesh, the multiple pores increase the interaction between the waves and the mesh, so that the wave energy is absorbed and dissipated when passing through the mesh, and the wave absorption effect is improved. The mesh structure of the frame 161 and the damping plate 162 is combined to help improve the damping performance of heave and roll motion, effectively reduce the impact of waves, and improve the stability and safety of the dynamic submarine cable 2.

[0050] Furthermore, the fixing rod 163 is used to connect and fix the frame 161 and the main body 11. In this embodiment, a plurality of fixing rods 163 are provided, and the plurality of fixing rods 163 are arranged on six side surfaces of the frame 161. The plurality of fixing rods 163 are fixedly connected to the frame 161 from the six side surfaces of the main body 11, thereby enhancing the stability of the connection between the frame 161 and the main body 11.

[0051] In this embodiment, a frame 161, a damping plate 162 and a fixing rod 163 are provided in the damping assembly 16, so that the frame 161 is sleeved and fixed to the outside of the main body 11 through the fixing rod 163, and a damping plate 162 with a mesh structure is covered on the outer side of the frame 161, so that the damping plate 162 can reduce the impact energy of the waves to a certain extent. The structure is simple and easy to install, and a good wave reduction effect is achieved.

[0052] In some embodiments, Figure 4 As shown, the mesh structure of this embodiment is a regular hexagonal mesh 1621.

[0053] It can be understood that the mesh structure is arranged in a regular hexagon. Due to the geometric symmetry of the regular hexagon, the force exerted by the wave on the mesh can be distributed more evenly. In addition, the regular hexagonal mesh 1621 can provide a larger surface area for interaction with waves, thereby increasing the dissipation of wave energy and improving the wave breaking effect. Based on the structural stability of the regular hexagonal mesh 1621, it helps the damping plate 162 to maintain its integrity when subjected to wave impact. At the same time, the regular hexagonal mesh 1621 has a regular structure and can be arranged closely, which is more economical in occupying space.

[0054] In some embodiments, Figure 1 As shown, the clamp 12 of this embodiment includes a first clamping member, a second clamping member and a fastener.

[0055] The first clamping member and the second clamping member are arranged opposite to each other along the height direction of the body 11 , and a clamping opening for clamping the dynamic submarine cable 2 is formed between the first clamping member and the second clamping member.

[0056] The fastener is used to fix the side edges of the first clamping member and the second clamping member.

[0057] It can be understood that the first clamping member and the second clamping member form a clamping opening along the horizontal direction, and the clamping opening can clamp the dynamic submarine cable 2. The fasteners are fixedly connected from the sides of the first clamping member and the second clamping member, so that the first clamping member and the second clamping member are firmly connected, so that the clamping opening forms an enclosed space, preventing the dynamic submarine cable 2 from slipping out of the clamping opening, and ensuring the reliability and stability of the first clamping member and the second clamping member in clamping the dynamic submarine cable 2.

[0058] Specifically, the fasteners may be bolts and nuts, the bolts are passed through threaded holes on the first clamping member and the second clamping member, and the nuts are used to fix the first clamping member and the second clamping member together.

[0059] Furthermore, the first clamping member and the second clamping member may be metal members, and in order to resist corrosion from seawater, anti-rust paint is applied on the outer wall surfaces of the first clamping member and the second clamping member.

[0060] In some embodiments, Figure 1 As shown, the clamp 12 of this embodiment further includes: an anti-slip washer.

[0061] The anti-skid washer is arranged on the inner side of the clamping opening, and the anti-skid washer is clamped between the first clamping piece, the second clamping piece and the dynamic submarine cable 2 .

[0062] It is understandable that the anti-skid gasket is used to increase the friction between the first clamping member, the second clamping member and the dynamic submarine cable 2, and when waves hit, the anti-skid gasket can absorb part of the energy, reduce the direct impact of the waves on the first clamping member and the second clamping member, and play a shock-absorbing role.

[0063] Specifically, the anti-slip gasket may be a rubber gasket.

[0064] In some embodiments, Figure 1 As shown, the mooring assembly 15 of this embodiment includes: a rotating wheel, a mooring rope and a mooring anchor.

[0065] The rotating wheel is rotatably disposed at the bottom of the body 11, one end of the mooring rope is wound around the rotating wheel, and the other end of the mooring rope is connected to the mooring anchor.

[0066] It is understandable that the rotating wheel is installed at the bottom of the body 11 through a bracket, and one end of the mooring rope can rotate around the rotating wheel to achieve the collection and release of the mooring rope. The other end of the mooring rope is connected to a mooring anchor, which is used to be fixed to the seabed.

[0067] When the dynamic submarine cable auxiliary device 1 is being installed, the mooring rope is in a state of being reeled in, and the mooring anchor moves to a preset position as the main body 11 moves. Then, the rotating wheel is rotated to release the mooring rope, so that the mooring anchor can move from the main body 11 to the seabed and be fixed on the seabed, completing the mooring positioning of the main body 11. The mooring rope generates a pulling force on the main body 11, realizing the S-shaped structural operation of the dynamic submarine cable 2.

[0068] In this embodiment, a rotating wheel, a mooring rope and a mooring anchor are arranged in the mooring assembly 15, the rotating wheel is used to realize the retraction and release of the mooring rope, and the mooring anchor is used to realize the mooring fixation of the mooring rope on the seabed, so that the mooring system can switch between the installation state and the mooring state, thereby achieving a good mooring effect.

[0069] In some embodiments, Figure 1 As shown, the dynamic submarine cable auxiliary device 1 of this embodiment further includes: a warning component 17.

[0070] The warning component 17 is disposed at a corner of the top end of the body 11 , and the warning component 17 is used to sound an alarm when a foreign object approaches the dynamic submarine cable 2 .

[0071] It is understandable that after the dynamic submarine cable auxiliary device 1 is installed, the warning component 17 is activated. When a foreign ship or creature approaches the dynamic submarine cable 2, the warning component 17 triggers an alarm to warn the foreign ship or creature to avoid accidental damage to the dynamic submarine cable 2, thereby ensuring the stability of the dynamic submarine cable 2 and increasing the service life of the dynamic submarine cable 2.

[0072] Optionally, the warning component 17 of this embodiment can be an infrared alarm system, which can realize non-contact detection, has high sensitivity and rapid responsiveness, can continuously emit infrared rays, and automatically alarm when detecting foreign objects approaching the dynamic submarine cable 2, thereby improving the safety of the dynamic submarine cable 2.

[0073] Furthermore, in some embodiments, Figure 1 As shown, the buoyancy chamber 13 of this embodiment can be made of glass beads or anti-sinking and buoyant materials. In addition, two buoyancy chambers 13 of this embodiment are provided, and the two buoyancy chambers 13 are arranged in the inner cavity of the body 11 at intervals. The buoyancy chambers 13 provide buoyancy for the body 11 and the dynamic submarine cable 2, so that the dynamic submarine cable 2 can float on the sea surface.

[0074] In a second aspect, in some embodiments, as Figure 5 and Figure 6 As shown, this embodiment provides a shallow water floating photovoltaic system, including: a dynamic submarine cable 2, a floating photovoltaic 3 and the above-mentioned dynamic submarine cable auxiliary device 1.

[0075] Specifically, since the shallow water floating photovoltaic system includes a dynamic submarine cable auxiliary device 1, the specific structure of the dynamic submarine cable auxiliary device 1 refers to the above embodiment, and the shallow water floating photovoltaic system shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0076] It is understandable that the floating photovoltaic 3 floats on the sea surface through a floating platform and is moored to the seabed through a mooring device.

[0077] One end of the dynamic submarine cable 2 is connected to the floating photovoltaic 3, and the other end of the dynamic submarine cable 2 is connected to a fixed wind turbine or connected to the shore to achieve power transmission. The dynamic submarine cable auxiliary device 1 is used to construct the dynamic submarine cable 2 into an S-shaped setting. The dynamic submarine cable auxiliary device 1 is used to quickly construct the S-shaped setting during the construction of the dynamic submarine cable 2 to resist the pulling force on the dynamic submarine cable 2 caused by the movement of the floating photovoltaic 3 due to the coupling of wind, waves and currents, thereby ensuring the safety of the dynamic submarine cable 2.

[0078] In the actual installation process, if Figure 5 As shown, when installing the auxiliary device 1 on the dynamic submarine cable 2, one end of the dynamic submarine cable 2 is connected to the floating photovoltaic 3, and the dynamic submarine cable 2 is arranged in a straight line. The clamp 12 is first pre-installed on the dynamic submarine cable 2, and the fasteners are not completely tightened. The pushing assembly 14 pushes the body 11 onto the dynamic submarine cable 2, so that multiple auxiliary devices 1 are arranged on the dynamic submarine cable 2 at intervals, and then the fasteners are tightened, and the auxiliary device 1 is firmly fixed on the dynamic submarine cable 2. Figure 6 As shown, the rotating platform 142 on the propulsion assembly 14 rotates according to a preset angle, the propulsion assembly 14 pushes the body 11 to a set position according to a preset line, the mooring assembly 15 performs mooring positioning, and finally, the warning assembly 17 is activated to complete the installation.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
