Anti-current device for diver's underwater action

Abstract

The invention relates to diving equipment, in particular to a flow-resisting device for the underwater action of a diver. The flow-resisting device is characterized by comprising a cabin, a direct-current motor, a transmission mechanism, a circuit board, a battery pack, an output shaft, a winding drum, a shield and a controller. The direct-current motor is arranged in the cavity of the cabin and drives the output shaft to rotate through the transmission mechanism. The output shaft is rotatably connected with the cabin. The cavity of the cabin is a watertight cavity. The winding drum is fixedly connected with the extended section of the output shaft. The shield is rotatably connected with the output shaft. The shield wraps the winding drum. A cable outlet is formed in the lateral part of the shield. The first end of a traction rope is electrically connected with the controller, and the second end of the traction rope is electrically connected with the direct-current motor. The flow-resisting device has the advantages that the flow-resisting device can provide external force support for the underwater action of the diver under large flow speed, and the underwater operation capability of the diver can be increased; the flow-resisting device is light, portable, simple to operate and widely applicable to the diving operations in marine engineering, salvage engineering and underwater maintenance.

Description

technical field [0001] The invention relates to equipment for diving, in particular to an anti-flow device for divers' underwater actions. Background technique [0002] In salvage engineering, marine engineering and other fields, underwater operations of divers are the main construction means. When divers perform underwater operations, they will be seriously affected by the current, and even unable to dive or perform underwater operations. For this reason, the "Diving Rules" require that: for self-contained diving, the maximum applicable water flow rate is 1.0 knots; for tube-supplied diving, the maximum applicable water flow rate is 1.5 knots. In order to meet the requirements of the "Diving Rules" and ensure the safety of divers' underwater operations, they have to arrange the diver's underwater operation time according to the tidal law when performing underwater operations. Underwater operations. This will lead to two problems. On the one hand, due to the limitation of...

Problems solved by technology

This will lead to two problems. On the one hand, due to the limitation of underwater operation time, the operation efficiency is seriously affected; Factors such as day and night operations and poor visibility at night will pose a serious threat to the safety of divers' underwater operations

Even sometimes when carrying out underwater operations in narrow waterways and other sea areas with large currents, even in flat tides, the current velocity will still exceed the allowable flow velocity for divers' underwater operations, which will make the operation impossible to implement
