Underwater wearable auxiliary robot

Abstract

The invention provides an underwater wearable auxiliary robot which comprises an air supply system, a buoyancy adjusting system and a controller, the buoyancy adjusting system is provided with a breathing adjuster, two sets of throttling valves and a buoyancy air bag, and the buoyancy air bag has a buoyancy state and an air leakage state; the breathing regulator can maintain the air pressure difference between the high-pressure chamber and the medium-pressure chamber, the buoyancy air bag can adjust the volume through inflation and deflation so as to adjust the buoyancy, and inflation and deflation are controlled by an air inlet throttling valve and an air outlet throttling valve respectively. Forward thrust is jointly provided by the propeller and the flipper pedaled by the diver, on one hand, the underwater moving speed is increased, the working range of underwater operation is expanded, on the other hand, the physical strength of the diver is saved, then the breathing gas consumption is saved, and the time of diving operation under the same gas cylinder capacity is prolonged.

Description

technical field [0001] The present invention relates to the field of underwater breathing systems for divers, in particular to an underwater wearable auxiliary robot. Background technique [0002] When scuba diving, divers need to be equipped with gas cylinders, breathing regulators, buoyancy adjustment devices, buoyancy adjustment equipment, counterweights, fins, diving computers and other equipment. The gas cylinder is filled with high-pressure air for breathing, etc., but people cannot directly inhale the high-pressure gas in the gas cylinder, which requires a breathing regulator to depressurize. Fins, also known as fins, have a larger area to increase the thrust of motion in the water. The buoyancy adjustment equipment and the counterweight work together to make the human body and equipment in a neutral buoyancy state. In addition, the diver needs to maintain a correct posture when moving underwater: the shoulders, hips and knees are basically in a horizontal line, and...

AI Technical Summary

Problems solved by technology

[0004] 1. The forward thrust is provided by the diver pedaling the fins, which not only has limited thrust, but also consumes a lot of physical strength, which will also increase the breathing air consumption

[0005] 2. Maintaining a correct underwater posture requires not only skilled skills, but also correct equipment settings, both of which are indispensable

[0007] Patent document CN213057449U discloses a dry suit with a diving aid, the dry suit with a diving aid is provided with a water resistance sheet, during use, when the diver's arm slides backwards, the water resistance sheet opens On, it increases the contact area between the human arm and the water. When the diver's arm is straightened forward, the water resistance sheet is closed, which reduces the water resistance. Wrong, resulting in more wasted physical effort, and the device has no additional power to help the diver move;

[0008] Patent document CN107336818A discloses a wearable underwater exoskeleton support system. Through the setting of buoyancy system, breathing system and propulsion system, this device can assist the human body to carry out activities underwater, so that the human body can swim faster when moving underwater. Fast and labor-saving, when the propulsion system loses power, it cannot provide labor-saving assistance to underwater divers
