Description

Technical Field

[0001] The utility model relates to the technical field of shipwreck salvage, in particular to a connecting device for oil suction from a shipwreck. Background Art

[0002] Oil leaks from sunken ships often cause marine pollution. Oil is a highly polluting chemical and requires prompt treatment to minimize contamination. Drilling, pumping, and sealing are common methods for recovering sunken ships.

[0003] Underwater drilling operations are fundamental to shipwreck recovery, and the drilling method significantly impacts the structure and operation of drilling tools. Currently, drilling methods are primarily categorized as non-contact drilling and contact drilling. Some current underwater drilling equipment essentially integrates a drilling unit with an oil extraction unit, drilling the hole through the drilling unit, and pumping oil through the hole created by the drilling unit. However, the integration of these drilling units results in a complex structure and relatively high cost. Utility Model Content

When the elastic sheet moves upward, it will engage with the upper end of the connecting part, which is convenient for fixation.

[0011] Furthermore, a communicating flow cavity is provided in the sleeve and the mounting member.

[0012] Through the above improvements, the sleeve and the interior of the mounting piece are provided with a communicating flow cavity, so that the oil in the cabin can smoothly enter the oil suction device from the flow cavity, thereby preventing leakage.

[0013] Furthermore, a positioning buckle is provided on the mounting member, and the positioning buckle is arranged perpendicular to the mounting member.

[0014] Through the above improvements, a positioning buckle is provided on the mounting piece, and the positioning buckle can play a positioning effect after the mounting piece is fixedly connected.

[0015] Furthermore, the wrench includes a mounting ring and a force rod. The mounting ring is sleeved on the outside of the sleeve and fixed by threaded engagement. A plug-in slot is provided on the outside of the mounting ring. The force rod is provided in conjunction with the plug-in slot and connected by threaded engagement.

[0016] Through the above improvements, the wrench includes a mounting ring and a force rod. The mounting ring is arranged on the outside of the sleeve and is fixed to the sleeve through threaded cooperation, so that the mounting ring can be stably fixed on the sleeve. The force rod of the wrench is fixed on both sides of the mounting ring through threaded connection. The connection is stable, so that when the wrench is rotated, it can drive the expansion joint to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 3 The shown device is a connection device for sucking oil from a sunken ship, comprising a sleeve 1 and a wrench 2. The sleeve 1 is provided with a thread, and the wrench 2 is sleeved on the outside of the sleeve 1 through a threaded connection. The sleeve 1 comprises a connecting portion 1.1 and a plug-in portion 1.2. The connecting portion 1.1 is connected to the oil suction device. A mounting member 3 is provided at the lower end of the plug-in portion 1.2, and the mounting member 3 extends into the piercing plate. An expansion joint 4 is sleeved on the outside of the connecting portion 1.1, and the lower end of the expansion joint 4 abuts against the upper end of the wrench 2. After the insertion is completed, the wrench 2 is rotated to lift the expansion joint 4, and the expansion joint 4 is engaged with the connecting portion 1.1.

[0024] The sleeve 1 includes a connecting part 1.1 and a plug-in part 1.2. A mounting part 3 is provided at the lower end of the plug-in part 1.2. The mounting part 3 is fixed to the plug-in part 1.2 by a threaded connection, and the connection is relatively stable. A positioning buckle 3.1 is provided on the mounting part 3. The positioning buckle 3.1 is arranged perpendicular to the mounting part 3, so that after the device is connected to the cabin, the positioning buckle 3.1 can play a positioning effect, thereby confirming whether the connection is firm.

[0025] The sleeve 1 and the mounting member 3 are provided with a communicating flow cavity 1.3 inside, so that the oil in the cabin can smoothly enter the oil suction device from the flow cavity, thereby preventing leakage.

[0026] The wrench 2 is set on the outer wall of the sleeve 1 through a threaded connection on the outer wall of the sleeve 1. The wrench 2 includes a mounting ring 2.1 and a force rod 2.2. The mounting ring 2.1 is sleeved on the outside of the sleeve 1 and is fixed to the sleeve 1 through threaded cooperation, so that the mounting ring 2.1 can be stably fixed on the sleeve 1. A plug-in groove 2.11 is provided on the outside of the mounting ring 2.1, and a thread is also provided inside the plug-in groove 2.11. The force rod 2.2 of the wrench 2 is fixed on both sides of the mounting ring 2.1 through a threaded connection. The connection is stable, so that when the wrench 2 rotates, it can drive the expansion joint 4 to rotate.

[0027] An expansion joint 4 is also provided on the outside of the sleeve 1. The expansion joint 4 includes a shell 4.1 and a bearing part 4.2. The bearing part 4.2 is arranged in the mounting groove 4.11 of the shell 4.1. The upper end surface of the bearing part 4.2 is against the mounting groove 4.11, and the lower end is against the upper end of the mounting ring 2.1.
