The invention discloses an offshore pile foundation anode block mounting device which comprises an underwater moving carrier, an anode block fixing device, an anode block fixing device, an anode block fixing device, an anode block fixing device, an anode block fixing device, an anode block fixing device, an anode block fixing device and an anode block fixing device. The positioning assembly is arranged on the carrier framework and used for holding and fixing the equipment on the pile foundation; the anode block conveying and loading mechanism is arranged on the carrier framework and used for clamping and conveying the anode block and pressing and fixing the anode block to a preset position on the outer wall of the pile foundation; and the anode block welding mechanism is arranged on the carrier framework and is used for automatically welding the anode block fixed on the pile foundation. The device can completely replace underwater operation of divers, and the winding risk caused by eddy current around a pile foundation, the scratch risk caused by construction sundries and the specific risks such as underwater oxygen deficit and decompression sickness of the divers are avoided; operators do not need to be in contact with the underwater dangerous environment, and diver casualty accidents frequently occurring all year round during pile foundation anode block installation operation are fundamentally eradicated.

The invention belongs to the technical field of diving safety, and particularly relates to a diver-oriented intelligent pressure reduction stop point dynamic planning and real-time navigation method, which comprises the following steps of: acquiring and processing dynamic information such as ocean current, water body parameters and physiological states of divers in real time to construct a three-dimensional dynamic environment field model; the environmental disturbance is quantitatively analyzed, so that the decompression stop point position of the diver is dynamically adjusted to adapt to the environmental change; meanwhile, acoustic positioning and inertial navigation technologies are combined, the real-time position of the diver is accurately corrected, and the navigation accuracy is ensured; the system intelligently selects an optimal ascending path according to physiological data such as blood oxygen saturation of the diver, decompression sickness is avoided, and the safety of diving operation is further improved; therefore, through real-time analysis and comprehensive application of multi-dimensional data, dynamic changes in a complex underwater environment are effectively dealt with, and the safety and efficiency of diving operation are remarkably improved.

The application provides an emergency floating lifesaving device, belonging to the technical field of lifesaving devices at sea, comprising a wearable base, which contains a folding floating airbag in a cabin. The base is internally provided with an inflation assembly, a double trigger mechanism and a constant-speed damping release mechanism; the bottom of the floating airbag is connected with the constant-speed damping release mechanism through a traction rope. The double trigger mechanism comprises a manual pull ring and a hydrostatic pressure self-starting assembly, which can automatically trigger the inflation assembly when a person loses consciousness and sinks, so that high-pressure gas is instantaneously filled into the airbag to generate a huge buoyancy. When the airbag floats, the traction rope is pulled, the winding drum of the damping mechanism is rotated, the internal centrifugal flyweights are thrown out by centrifugal force and generate dynamic damping with the friction inner ring, so that the safe floating speed is forcibly limited. The application realizes automatic self-rescue triggering and constant-speed safe floating in a passive environment, and effectively prevents decompression sickness.
