A water and air separation device for marine robots

Abstract

The invention belongs to the field of marine robots, and in particular relates to a water and air separation device for the marine robots. An air intake mast is sealedly connected with a front end cover of a water tank body through a mast seat, a front water baffle and a rear water baffle are respectively installed in the water tank body, and an intermediate partition is connected between the front and rear water baffles to form a gas flow field with the front and rear water baffles. A water flow field is formed between the lower part of the intermediate partition and the water tank body; an inner air intake pipe is installed on the front end, one end of the inner air intake pipe is connected with the air intake mast, and the other end of the inner air intake pipe passes through the frontwater baffle, and faces the rear water baffle, a through hole A is arranged at a position, on the rear water baffle, opposite to the other end of the inner air intake pipe. An inner air outlet pipe isinstalled on a rear end cover, one end is located outside the water tank body, and the other end passes through the rear water baffle, and faces the front water baffle. The water and air separation device fully utilizes the principle that the mass of water and the mass of the air differs greatly and the inertia of the water and the inertia of air greatly differs to achieve the separation of the in-taken air inlet and the liquid water, the structure is simple, and the processing technology is good.

Description

technical field [0001] The invention belongs to the field of marine robots, and specifically relates to a water-air separation device for marine robots, which is suitable for marine robots with high-speed airflow, especially for fuel-powered marine robots that directly exchange gas with the outside. Background technique [0002] For fuel-powered underwater unmanned robots, in poor sea conditions and rainy days, seawater or rainwater easily enters the intake pipe through the mast, and is splashed on the equipment in the cabin driven by high-speed airflow, which may cause a short circuit in serious cases and damage the equipment cause serious damage. Existing water-air separation technologies include barrier type (baffle type), gravity sedimentation type, centrifugal type and filter screen type, but marine robots require small size and light weight, and the diameter of the intake pipe is often limited, resulting in high-speed intake airflow ( 45m / s or more), the separation ef...

Existing water-air separation technologies include barrier type (baffle type), gravity sedimentation type, centrifugal type and filter screen type, but marine robots require small size and light weight, and the diameter of the intake pipe is often limited, resulting in high-speed intake airflow ( 45m / s or more), the separation effect of blocking type (baffle type), centrifugal type and gravity sedimentation type drops sharply, and the high-density filter screen has a large air intake resistance, which is not suitable for gas turbine systems
