Problems solved by technology
This traditional emergency response cannot take advantage of the power system of the single-person atmospheric pressure diving suit itself in an emergency, and there is still a certain degree of blindness in forced recovery
In addition, if the dangerous situation encountered by the single-person atmospheric pressure diving equipment is that the neutral cable is entangled during the operation, which completely limits the mobility of the equipment itself, then the above-mentioned traditional emergency response cannot achieve emergency escape at all, and still cannot ensure Safety of underwater workers

Embodiment Construction
[0030] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0031] See figure 1 , figure 2 , image 3 , the present invention includes a shearing cylinder 2 and a pressurized cylinder 3 fixedly mounted on the body 1 of the single-person normal-pressure diving equipment, the first piston rod 201 of the shearing cylinder 2 passes through the mounting hole on the lifting rod 4, and is locked On the body 1 of the single-person atmospheric pressure diving equipment, the lifting rod 4 is connected to the cable joint 5 through the pin shaft 6, and the neutral cable 7 laid on the relay station passes through the cable joint 5 and the first rodless cavity of the shearing cylinder 2 in sequence. After 202, it is connected with the cabin body of the single-person atmospheric pressure diving equipment body 1; the first rodless chamber 202 of the shearing oil cylinder 2 is provided with a shearing knife 8, a...

A hydraulic shearing device for the emergency of a single person normal pressure diving apparatus comprises a shearing oil cylinder and a boosting oil cylinder which are fixedly arranged on a single person normal pressure diving apparatus body; a piston rod of the shearing oil cylinder penetrates through a hoisting rod and is locked on the single person normal pressure diving apparatus body; the hoisting rod is connected with a mooring rope connector; a medium cable placed on a relay station penetrates through the mooring rope connector and a rodless cavity of the shearing oil cylinder in sequence to be connected with a cabin body of the single person normal pressure diving apparatus body; a shearing cutter is arranged in the rodless cavity of the shearing oil cylinder and is fixedly connected with the piston rod of the shearing oil cylinder by a cutter rest; one end, extending out of the cylinder body of the boosting cylinder, of the piston rod of the boosting cylinder is connected with a handle; the piston rod of the shearing oil cylinder and the corresponding cylinder body as well as the piston rod of the boosting cylinder and the corresponding cylinder are both hermetically connected; a hydraulic oil pipeline is arranged between a rod cavity of the shearing oil cylinder and a rod cavity of the boosting oil cylinder. The external constraint of the apparatus can be relieved as the apparatus body and the relay station can be separated by cutting off the medium cable, so the emergency rescue of the apparatus is realized and the work is reliable.
Description
technical field [0001] The invention relates to the technical field of underwater operation devices, in particular to underwater operation devices applied to underwater cable-controlled moving bodies such as single-person atmospheric pressure diving equipment and cable remote-controlled underwater robots, and in particular to underwater operation devices applied to single-person atmospheric pressure diving When the equipment escapes, the equipment body is separated from the relay station by cutting off the neutral cable, so as to release the external restraint of the equipment and realize the hydraulic shearing device for emergency escape of the equipment. Background technique [0002] The single-person atmospheric diving system is mainly composed of three parts: the single-person atmospheric diving suit (ADS), the relay station (TMS) and the surface deployment recovery system (LARS). Among them, the single-person atmospheric pressure diving suit is a humanoid underwater ope...
