Description
Technical Field
[0001] This utility model relates to the field of underwater welding technology, and in particular to a retractable insulated operating arm for underwater welding. Background Technology
[0002] Underwater welding is a welding operation performed in an underwater environment, typically used to repair or construct underwater structures such as subsea pipelines, ship hulls, and platforms. This technology addresses equipment damage or structural repairs during underwater operations, especially in inaccessible areas like the deep sea. Underwater welding can be divided into wet and dry methods. Wet welding is performed directly in the water, while dry welding uses specific sealing devices to isolate the operating area from the outside environment. Manipulators are closely related to underwater welding, particularly in deep water or hazardous working environments. They are often used to remotely control welding tools, ensuring operational safety and precision. In summary, underwater welding is an important technology that addresses underwater engineering needs that traditional welding methods cannot meet by performing welding repairs in water, while manipulators enhance operational safety and flexibility.
[0003] The working principle of an underwater welding manipulator primarily relies on remote control technology. Through the collaborative work of the robotic arm and corresponding sensors and control system, an operator can remotely control welding tools from the water's surface to complete underwater welding tasks. The manipulator typically consists of multiple joints, enabling high-precision movement and positioning, and is usually equipped with video cameras to monitor the welding area in real time. The control system translates the operator's commands into precise mechanical movements, while transmitting power and signals via cable or wireless technology. The manipulator can connect to underwater welding equipment to perform tasks such as arc welding and cutting, ensuring safety and efficiency even in harsh environments. In this way, underwater welding operations can be completed in complex environments such as the deep sea, avoiding the risks of direct underwater welding work for divers.
[0004] In existing technologies, some underwater welding manipulators, when performing long-distance and complex work, are inconvenient for workers to perform welding work due to the fixed arm length principle of the equipment. When the equipment is in standby mode, most underwater welding manipulators, because they are designed to wrap the welding parts, may cause damage to the welding head when workers are performing other operations at the workstation due to equipment failure or accidental contact. Therefore, a telescopic insulated manipulator for underwater welding is proposed to solve the above problems. Utility Model Content

[0033] Working Principle: The device is fixed to the welding area via the main base 1. Then, through the cooperation of the square waterproof block 2, waterproof block 8, and waterproof block 13, the working direction adjustment motor 21, the working angle adjustment motor 7, and the working motor located inside the telescopic arm 10 are activated. Specifically, the square waterproof block 2 protects the working direction adjustment motor 21, the waterproof block 8 protects the working angle adjustment motor 7, and the waterproof block 13 protects the working motor inside the telescopic arm 10, preventing the risk of electric leakage during underwater operation. Simultaneously, the working direction adjustment motor 21 drives the adjustment block 3 to rotate, thus adjusting the operating arm base 4. This allows the device to adjust its working direction. Then, the position adjustment motor 5 starts, driving the robotic arm 6 to rotate, enabling the device to adapt to welding at different heights. Then, the working angle adjustment motor 7 starts, driving the connecting arm 9 to rotate, enabling the device to adapt to different welding angles. Meanwhile, the working motor inside the telescopic arm 10 drives the working arm 12 to rotate, allowing the device to weld different lengths. With the cooperation of the above structures, the device can adapt to different working environments. At the same time, the telescopic push rod 11 located inside the connecting arm 9 can push the telescopic arm 10 to slide, thereby extending the welding range and enabling the device to adapt to welding at different distances.
[0034] During welding, the clamping drive motor 14 starts, causing the adjusting screw 15 to rotate. The external thread of the adjusting screw 15 causes the sliding operating block 16 to slide. Then, with the cooperation of the rotating connecting block 17 and the jaw connecting block 18, the clamp 19 slides. Due to the restriction of the guide limiting block 20, the sliding of the clamp 19 is converted into rotation, causing the two clamps 19 to move closer to each other, and finally complete the clamping of the weldment, thus completing the welding function.
