Description

Technical Field

[0001] This utility model relates to shipwreck salvage technology, and in particular to an underwater mud-tapping device suitable for salvaging shipwrecks in shallow inland waters. Background Technology

[0002] In recent years, with the continuous development of my country's economic construction, waterway freight transportation has become an inevitable choice. While waterways are becoming increasingly busy, the risk of ship collisions and sinkings is also rising. How to quickly, safely, and effectively salvage sunken ships to minimize losses has become a top priority. The "bottom-penetrating jack method" is a commonly used method in current shipwreck salvage, which involves passing a jack (steel cable) through the bottom of the ship to be salvaged to lift it. However, existing underwater drilling rigs require a mother ship and a floating platform, which limits the deployment of the equipment and also poses significant risks to construction and navigation safety. Especially when the sunken ship is deeply buried, the drilling angle is large, or construction is carried out during the dry season when the water depth does not meet the site layout requirements, the bottom-penetrating jack method is difficult to handle in such complex construction environments. Furthermore, the high equipment investment cost limits its applicability. Utility Model Content

In one or more embodiments, the front end wall of the terminal injection pipe 8 is evenly distributed with multiple pipe holes 9 serving as compressed air outlets. Multiple intermediate injection pipes are provided between the front-end injection pipe 1 and the terminal injection pipe 8.

[0024] The mud-tapping device connector is provided with a water inlet 3 connected to an external water source, and an inlet switch 4 is provided on the water inlet 3 pipeline; the mud-tapping device connector is provided with a pressurization port 5 connected to a fire hose, and the outlet of the pressurization port 5 is connected to the output end of the water inlet 3 and the inlet of the front spray pipe 1 respectively; the mud-tapping device connector is provided with an air inlet 6 connected to an external air source, and the outlet of the air inlet 6 is connected to the output end of the water inlet 3 and the inlet of the front spray pipe 1 respectively, and an air inlet switch 7 is provided on the air inlet 6 pipeline; in one or more embodiments, the pressurization port 5 and the air inlet 6 are located on both sides of the water inlet 3, and the mud-tapping device connector is generally shaped like a mountain.

[0025] The technical principle of this utility model is as follows:

[0026] Pressure port 5: Can be connected to an external fire hose 10, which can increase water pressure and enhance the water flow penetration effect.

[0027] Inlet 3: The injected water flow disperses the sand pile, allowing the diver 11 to feed the underwater mud-attacking device 12 and extend the pipeline.

[0028] Inlet switch 4: Controls the water flow into the underwater mud-tapping device 12.

[0029] Air inlet 6: Compressed air is introduced, and bubbles 13 emerge from the pipe hole 9 on the last jet pipe 8, which makes it convenient for the diver 11 and the diver 11 on the opposite working well, as well as the shore personnel, to grasp the actual penetration situation, so as to control the penetration direction and realize the threading of the steel cable.

[0030] Air inlet switch 7: controls the intake of compressed air into the underwater mud-tapping device 12.

[0031] Front jet pipe 1: One end is connected to the mud-tapping device connector, and the other end is connected to the intermediate jet pipe (the number of intermediate jet pipe sections can be increased according to the actual width of the bottom of the sunken ship 14). Compressed air or high-pressure water jets are delivered to the next jet pipe section through the front jet pipe 1.

[0032] Terminal injection pipe 8: The final injection pipe with pipe holes 9. Compressed air or high-pressure water jet is delivered along this pipe to the end nozzle 2.

[0033] Pipe hole 9: Located on the end jet pipe 8, it allows compressed air bubbles 13 to emerge from here, making it easier for divers, divers 11 on the opposite working well, and shore personnel to monitor the actual penetration situation, so as to control the penetration direction and realize the threading of the steel cable.

[0034] Nozzle 2: Located at the front port of the end spray pipe 8, from which high-pressure water jets and compressed air flow out.

[0035] See Figure 2 This utility model is applicable to the underwater mud-tapping tool for salvaging sunken ships in shallow inland waters. Detailed underwater operation steps are as follows:

[0036] 1. Positioning Measurement

[0037] According to the predetermined locations of the bottom jack holes in the construction plan, the air supply pipe 15 of the diver on the workboat 16 is connected to the diving suit of the diver 11. The diver 11 moves along the bow and stern of the sunken ship 14, accurately measures the location of each jack hole, and marks it.

[0038] 2. Excavation of the working well

[0039] ① Divers used high-pressure water guns to spray the 14th side of the sunken ship.

[0040] ② The excavation depth must be lower than the bottom reference surface of the sunken ship 14, and the length and width dimensions must meet the operational needs of diver 11;

[0041] ③ Simultaneously excavate working wells of the same specifications at symmetrical positions on the sunken ship 14 to ensure symmetrical working surfaces on both sides.

[0042] 3. Mud removal operation

[0043] (1) Connect the fire hose 10 and the mud-tapping device supply pipe 17 on the workboat 16 to the underwater mud-tapping device 12;

[0044] (2) Diver 11 uses underwater mud-tapping tool 12 to perform directional drilling operations in the working well;

[0045] (3) Use the high-pressure water jet ejected from the nozzle at the end of the underwater mud-attacking device 12 to impact the mud and sand at the bottom of the ship to form a channel;

[0046] (4) The end jet pipe 8 reflects water holes to continuously discharge the dispersed mud and sand, keeping the channel unobstructed;

[0047] (5) After each intermediate jet pipe section is completed, the direction is immediately checked, and any deviation is adjusted in time to ensure the accuracy of the perforation path.

[0048] 4. Cable threading operation

[0049] (a) Air tightness test

[0050] After advancing the predetermined number of intermediate injection pipe sections, connect the compressed air system. By observing the bubbles 13 emerging from the end pipe, the overflow of bubbles 13 from the opposite working well confirms that the channel is connected.

[0051] (II) Traction Construction

[0052] The diver on the opposite side positions the front end of the underwater mud-tapping tool 12, and the connecting guide wire adopts a staged traction process:

[0053] a) The first stage involves traction of the thin steel wire across the bottom;

[0054] b) The second stage involves pulling the thick steel wire cable with a thin steel wire;

[0055] c) Repeat the operation until the steel cable that meets the load-bearing capacity requirements is in place.
