The invention discloses an underwater self-release detacher comprising a self-release structure, a shell, a connecting block and a supporting block. The self-release structure is arranged in the shell. One end of the connecting block is arranged at the top of the shell. The connecting block is arranged on the supporting block. The supporting block is rotatably connected with the connecting block.The other end of the connecting block is provided with an iron ball. A lifting rope connected with a heavy object hangs on a hook body, and the hook body bears the force to be pressed down to drive arotating rod, a sliding rod, a driven rod, a connecting rod and a limiting rod to do motion, so that the limiting rod locks the hook body; and when the hoisted object touches the ground and accordingly does not bear gravity, a spring arranged on the hook body rebounds to drive the hook body to move upwards, so that the limiting rod unlocks the hook body. The underwater self-release detacher can realize self release under the condition of not bearing the gravity, so that the hoisting efficiency is improved; and meanwhile taking the hook manually by a diver is not needed, thereby avoiding hiddendanger of accidental injuries to the diver during the underwater hoisting process, and increasing the safety factor of the diver.
Description
technical field [0001] The invention belongs to the technical field of hoisting equipment, in particular to an underwater self-decoupling device. Background technique [0002] Hoisting refers to the general term for the installation and positioning of equipment by cranes or lifting equipment. In the process of overhaul or maintenance, various hoisting tools are used to lift equipment, workpieces, utensils, materials, etc. to change their positions. In the process of underwater construction, underwater hoisting operations of structures are often encountered. [0003] The hoisting equipment cannot be unhooked underwater, and it is necessary to cooperate with divers to unhook the hoisting equipment and the hoisted object under water. However, the process of divers unhooking increases the safety factor of divers themselves, and there is a hidden danger of accidental diver injury. Contents of the invention [0004] The purpose of the present invention is to solve the above-men...
