Abstract
The utility model provides a marine motor muffler, the technical proposal of which is that: an inlet pipe and an outlet pipe of the muffler are longer, which makes a shell of the muffler in water fully and in a U shape. A tank of the muffler is provided with a plurality of slant silencing plates. As the tank is provided with a plurality of silencing plates, the course that the gas discharged by motor of a vessel enters into the tank of the muffler increases the silencing effect. As the shell of the muffler is fully in water, most of the noises, oscillating waves are absorbed by water, thus reducing noise pollution of motor of the vessel.
Description
One, technical field: the utility model relates to a kind of internal combustion engine noise elimination device, particularly a kind of motor silencing apparatus peculiar to vessel.
Two, background technique: existing ship is exposed to the space basically with the main muffler part of motor silencing apparatus, and noise is big, and noise transmission is also far away, and the noise pollution that causes has thus had a strong impact on people's life.
Three, summary of the invention: the utility model is exactly at the problems referred to above, a kind of motor silencing apparatus peculiar to vessel is provided, its technological scheme is: suction tude, the outlet pipe of silencing apparatus are longer, make muffler shell fully in water, take the shape of the letter U, the silencing apparatus inner bag is provided with a plurality of oblique acoustical panels, and acoustical panel is provided with bloop, acoustical panel and wall of inner container are 15-90 degree angle, and the suction port of silencing apparatus and relief opening are at same horizontal line.The gas that boat motor is discharged enters in the process of silencing apparatus inner bag, because of inner bag is provided with a plurality of acoustical panels, has increased the erasure effect of silencing apparatus.Because in water, most of noise, shock wave are absorbed by water the shell of this silencing apparatus, thereby alleviate the noise pollution of boat motor fully.
Four, description of drawings: accompanying drawing is a structural representation of the present utility model;
Among the figure: 1. suction port, 2. suction tude, 3. shell, 4. inner bag, 5. acoustical panel, 6. outlet pipe, 7. relief opening.
Five, embodiment: the suction tude of silencing apparatus (2), outlet pipe (6) are longer, make muffler shell (3) fully in water, take the shape of the letter U, silencing apparatus inner bag (4) is provided with a plurality of oblique acoustical panels (5), acoustical panel (5) is provided with bloop, acoustical panel (5) is 15-90 degree angle with inner bag (4), and suction port of silencing apparatus (1) and relief opening (7) are at same horizontal line.
Claims (2)
1, a kind of silencing apparatus peculiar to vessel is characterized in that the suction tude of silencing apparatus, outlet pipe are longer, makes muffler shell fully in water, takes the shape of the letter U, and the silencing apparatus inner bag is provided with a plurality of oblique acoustical panels.
2, a kind of silencing apparatus peculiar to vessel according to claim 1 is characterized in that acoustical panel and inner bag are 15-90 degree angle.
