Description

Technical Field

[0001] This invention relates to an underwater delivery tool for precise positioning of underwater interlocking concrete delivery, and more particularly to a high-precision underwater interlocking concrete delivery tool. Background Technology

[0002] Currently, when constructing submarine cable protection systems, a type of concrete interlocking slab is commonly used to cover and protect the cables. The typical method for deploying these slabs involves roughly locating the deployment point, then using a crane vessel to lift and lower the slab directly from the point. Finally, divers or other underwater observation methods are used to monitor the deployment. However, due to the lack of direct observation and precise control over the slab's position during deployment, and its susceptibility to external forces such as ocean currents during descent, the traditional method suffers from poor deployment accuracy. This is especially true in deep water areas, where precise deployment in a single attempt is often difficult, requiring increased quantity and density of slabs to achieve the desired protective effect. This results in wasted construction materials, increased construction time, and increased safety hazards.

[0003] In view of the above, there is a need for a tool that can accurately locate, observe, and provide a certain degree of deviation correction capability during the deployment of underwater interlocking concrete slabs. Summary of the Invention

[0004] The present invention provides a high-precision underwater concrete interlocking pump delivery tool to solve the problem of accurate underwater concrete interlocking pump delivery.

[0005] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is: a high-precision underwater concrete interlocking delivery tool, including a central module, planetary modules, and a power supply and control module. The central module is connected to multiple planetary modules through planetary frame connecting arms. The power, communication and control systems of the planetary modules are aggregated to the power and control pod of the central module through a dedicated bus. The central module is connected to the power supply and control module through an umbilical cable to obtain power supply and communication control, thus forming a high-precision underwater concrete interlocking delivery tool.

[0006] Furthermore, the central module consists of a central frame, planetary frame connecting arms, a power and control pod, and an underwater positioning module. The planetary frame connecting arms extend outward from the four ends of the central frame to connect the planetary module. The power and control pod is located at the center of the central frame, and the underwater positioning module is located above the power and control pod to provide underwater positioning functionality for the high-precision underwater concrete interlocking delivery tool.

[0007] Furthermore, the planetary module consists of a planetary frame, a buoyancy chamber, and an underwater thruster. The buoyancy chamber is installed on the planetary frame, which provides buoyancy for the entire high-precision underwater concrete interlocking delivery fixture to reduce the underwater weight of the entire fixture. The underwater thruster is installed on the outer frame of the planetary frame, which provides the entire high-precision underwater concrete interlocking delivery fixture with the ability to translate, rotate, tilt, and pitch underwater.

[0008] Furthermore, the upper part of the planetary frame is equipped with a lifting ring, which is connected to the lifting slings using shackles and wire ropes to lift the entire high-precision underwater concrete interlocking delivery tooling.

[0009] Furthermore, a load-bearing ring is installed at the bottom of the buoyancy chamber to suspend construction loads.

[0010] Furthermore, the buoyancy chamber is connected to the lower interlocking frame-type lifting device via a load lifting ring, which is used for the precise sinking of the underwater concrete interlocking block.

[0011] Furthermore, an underwater sensor mounting platform is provided on the planetary frame, on which various underwater sensors can be installed as needed.

[0012] Furthermore, different types of buoyancy chambers and underwater propulsion units can be removed, added, or replaced on the planetary framework as needed for the mission.

[0013] Furthermore, the high-precision underwater concrete interlocking delivery tool is connected to the lifting slings and the lifting equipment on the construction vessel via steel wire ropes. The two ends of the umbilical cable are respectively connected to the power and control pod and the power supply and control module placed on the deck of the construction vessel. The umbilical cable is responsible for transmitting the power supply and control signals of the power supply and control module and the sensor feedback information on the high-precision underwater concrete interlocking delivery tool.

[0014] The beneficial effects of this invention are:

[0015] This invention can solve the problems of difficulty in accurately positioning protective materials such as concrete interlocking panels for submarine cable protection during the lifting and sinking process in water, and the sinking position is easily deviated by factors such as ocean currents. At the same time, it solves the problem of difficulty in real-time observation and correction of protective materials such as concrete interlocking panels during sinking construction.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 9 As shown, the high-precision underwater concrete interlocking delivery tool 1 of the present invention includes a central module 2, a planetary module 3, an umbilical cable 4, and a power supply and control module 5.

[0028] like Figure 6 As shown in Figure 7, the central module 2 consists of an underwater positioning module 7, a central frame 8, a power and control pod 9, and a planetary frame connecting arm 10. The planetary frame connecting arm 10 extends outward from the four ends of the central frame 8 and is used to connect with the planetary module 3; the power and control pod 9 is located at the center of the central frame 8, and the underwater positioning module 7 is located above the power and control pod 9.

[0029] like Figure 8As shown in Figure 9, the planetary module 3 consists of a planetary frame 11, a buoyancy chamber 12, an underwater thruster 13, an underwater sensor mounting platform 14, and an underwater sensor 15. The buoyancy chamber 12 is located at the center of the planetary frame 11. The underwater thruster 13 is installed on the outer frame of the planetary frame 11. The underwater sensor 15 is installed below the underwater sensor mounting platform 14. The upper part of the planetary frame 11 is provided with a frame upper lifting ring 16, which is connected to the lifting sling 21 by shackles 22 and wire ropes 23 to lift the entire high-precision underwater concrete interlocking deployment tool 1. The lower part of the buoyancy chamber 12 is provided with a load lifting ring 17 for suspending construction loads.

[0030] The high-precision underwater concrete interlocking delivery tool 1 is connected to the lifting sling 21 and the lifting equipment 27 on the construction vessel 26 via a steel wire rope 23. The two ends of the umbilical cable 4 are connected to the power and control pod 9 and the power supply and control module 5 placed on the deck of the construction vessel 26, respectively. The umbilical cable 4 is responsible for transmitting the power supply and control signals of the power supply and control module 5 and the sensor feedback information on the high-precision underwater concrete interlocking delivery tool 1.

[0031] like Figures 10 to 12 As shown, the high-precision underwater interlocking deployment tool 1 has load lifting rings 17 below its four planetary modules 3, which can be connected to the interlocking frame type lifting tool 6 and other construction loads via shackles 22 and wire ropes 23.

[0032] During construction operations, such as Figure 13 , 14 As shown, the concrete interlocking bar 24 is connected to the interlocking bar lifting ring 19 at the lower part of the interlocking bar frame type lifting device 6 through the automatic unhooking device 20. The interlocking bar frame type lifting device 6 is connected to the high-precision underwater interlocking bar deployment tool 1 through the upper lifting ring 18 of the upper frame type lifting device.

[0033] like Figures 15 to 17 As shown, the construction vessel 26 is positioned above the submarine cable 25 to be protected. The high-precision underwater interlocking deployment tool 1, carrying the concrete interlocking bar 24, is lifted by the lifting equipment 27. The high-precision underwater interlocking deployment tool 1 is used to lay the concrete interlocking bar 24 on the submarine cable 25. Then, the connection between the high-precision underwater interlocking deployment tool 1 and the concrete interlocking bar 24 is released by the automatic unhooking device 20. The lifting equipment 27 retrieves the high-precision underwater interlocking deployment tool 1 from the water to the deck of the construction vessel 26, and a new concrete interlocking bar 24 is re-suspended, so that the protection operation of the next section of the submarine cable 25 can be carried out.

[0034] like Figure 18As shown, during the sinking of the concrete interlocking barge 24, the high-precision underwater interlocking barge deployment tool 1 can confirm its own position and status at any time through the underwater positioning module 7, and can monitor the position of the submarine cable 25 in real time through various underwater sensors 15 installed on the underwater sensor installation platform 14. If the position of the high-precision underwater interlocking barge deployment tool 1 deviates significantly from the submarine cable 25 that needs to be protected, or if the high-precision underwater interlocking barge deployment tool 1 deviates from the deployment position due to water flow or other factors, the underwater thruster 13 installed on the planetary module 3 of the high-precision underwater interlocking barge deployment tool 1 can be activated to adjust the position and angle in real time to ensure accurate deployment.
