Technical Field

[0001] This utility model relates to the field of marine ventilation equipment technology, specifically a marine sound-absorbing ventilation louver. Background Technology

[0002] Ventilation louvers are an important component of ship cabin ventilation systems. Existing ship ventilation louvers mainly consist of a frame and louvers fixed within the frame. Their primary function is to regulate airflow within the cabin, effectively remove harmful gases and overheated air, and maintain fresh air inside the cabin. However, due to the special nature of ships, facilities such as fans on board generate a significant amount of noise, affecting the physical and mental health of people on board. Therefore, there is an urgent need for a shipboard sound-absorbing ventilation louver that can both facilitate airflow and reduce noise transmission. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the prior art and provide a marine sound-absorbing and ventilation louver that can not only facilitate air circulation but also reduce noise transmission and reduce the noise emitted by facilities such as fans, thereby greatly improving the working environment on board.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A marine sound-absorbing and ventilation louver includes a louver frame, in which a plurality of louvers are arranged sequentially from top to bottom. Each louver includes an arc-shaped louver plate with its convex surface facing upward, and a sound-absorbing component is provided on the bottom surface of the louver plate.

[0006] Preferably, the sound-absorbing component includes glass wool, glass cloth and aluminum alloy perforated plate arranged sequentially from top to bottom. The top and bottom surfaces of the glass wool are both arc-shaped, and the aluminum alloy perforated plate is an arc-shaped perforated plate with the concave surface facing upward.

[0007] Preferably, the left and right inner walls of the louver frame are provided with U-shaped grooves for installing louvers, and the ends of the louvers are riveted to the U-shaped grooves.

[0008] Preferably, the bottom of the louver frame is provided with a drain outlet.

[0009] Preferably, the drain outlet includes an internal threaded connector, an external threaded connector, and an internal threaded elbow arranged sequentially from top to bottom, with the internal threaded connector connected to the louver frame.

[0010] Preferably, the front side of the louver frame is provided with a bird-proof net.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The louver of this utility model consists of an arc-shaped louver plate and a sound-absorbing component set on the bottom surface of the louver plate, which gives the louver the function of noise reduction. It can not only complete the air circulation, but also reduce the transmission of noise and reduce the noise transmitted from facilities such as fans, thus greatly improving the working environment on the ship.
