The utility model provides a silencing elbow with circular seawater-proof horizontal inlets and outlets, as shown in figures 1-5, comprising: barrel shell 1, sound absorption filler 2, water inlet 3, interior barrel 4, elbow circulation passageway 5, sound absorption core 6, the welding has in the barrel shell 1 interior barrel 4, barrel shell 1 intussuseption is filled with sound absorption filler 2, the interval is provided with arc water conservancy diversion sound absorption core 6 in the interior barrel 4, forms elbow circulation passageway 5 between the adjacent arc sound absorption core 6, be provided with water inlet 3 on the inner wall of elbow circulation passageway 5, the one end of interior barrel 4 is provided with first circular mouth 7, the other end of interior barrel 4 is provided with second circular mouth 8. The bottom of the elbow flow channel 5 and the bottom of the arc-shaped diversion sound absorption core 6 are provided with waterproof edges 9. A water flowing gap 10 is arranged on one side, far away from the water flowing port 3, of the inner wall of the elbow flow channel 5, an inner cavity is arranged at the bottom of the inner cylinder 4, and the water flowing port 3 and the water flowing gap 10 are communicated with the inner cavity. The bottom of the cylinder shell 1 is provided with a drain hole 11, the drain hole 11 is communicated with the inner cavity, and the drain hole 11 is provided with a flange. The cylinder shell 1 is square box-shaped.

The technical scheme has the working principle and beneficial technical effects that: when the high-speed air flow enters the silencing elbow, the air flow is split into an elbow circulation channel 5 under the guidance of the arc-shaped diversion sound absorption core 6 through the second circular port 8 as shown in fig. 4; the air flow moves forward along the elbow flow channel 5 and is influenced by the structure of the arc-shaped diversion sound absorption core 6, so that the air flow is turned; finally, the air enters a first round opening 7 of the silencing elbow until the end of the air outlet forms a confluence, and the high-speed air flow is discharged out of the silencing elbow together; meanwhile, noise and air flow alternating noise generated in the flowing process of high-speed air flow are eliminated or degraded to meet a certain index noise reduction amount under the action of the sound absorption filler 2 between the silencing section of the arc-shaped diversion sound absorption core 6 and the inner cylinder 4 and the outer cylinder shell 1, so that the work flow of primary air inlet and noise reduction is completed, and circulation is continued. When meeting the seawater, the seawater is acted by gravity and flows into the water flowing port 3 along the elbow flow channel 5; enters the inner cavity under the guidance of the water flowing port 3 and the water flowing gap 10, finally discharges the seawater outside the silencing elbow through the water discharging hole 11, completes the primary seawater discharging flow, and then the circulation is continued. When the seawater generates water level, the waterproof edge 9 resists the seawater, so that the seawater is prevented from entering the sound absorption layer and the inside of the arc-shaped diversion sound absorption core body 3; the silencing elbow has the advantages of simple structure, convenient use and manufacture, and functions of effectively preventing or reducing the influence of noise generated at high speed on the outside, and enabling high-speed airflow to smoothly enter the silencing elbow and preventing seawater.
