Title:
MARINE VENTILATION RESISTANCE REDUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/216375
Kind Code:
A1
Abstract:
A marine ventilation resistance reduction device, comprising a main housing (1), an air inlet pipe (2), a partition plate assembly (3), a left rectification assembly (4), and a right rectification assembly (5). An air chamber (11) is formed in the main housing (1). The air inlet pipe (2) is inserted into the main housing (1), and is kept in communication with the air chamber (11). The partition plate assembly (3) is composed of a left vertical partition plate (31) and a right vertical partition plate (32) which are provided in the air chamber (11). The left vertical partition plate (31) and the right vertical partition plate (32) cooperate to divide the air chamber (11) into a left air sub-chamber (111), a lower ventilation seam (112), a first flow channel (113), an upper ventilation seam (114) and a right air sub-chamber (115) which are communicated in sequence. The left rectification assembly (4) used for performing primary rectification operation and the right rectification assembly (5) used for performing secondary rectification operation are arranged in one-to-one correspondence in the left air sub-chamber (111) and the right air sub-chamber (115). High-pressure air is rectified in the circulation process of the air chamber, thereby reducing the turbulence degree of the high-pressure air when the high-pressure air is introduced into the bottom of a hull, and facilitating the formation of a stable isolation air layer.
