A plurality of side wall flushing pipes 3 are evenly distributed on the main water pipe 2. One end of the side wall flushing pipe 3 away from the main water pipe 2 points to the inner wall of the sewage tank A.

[0042] The present embodiment provides a sewage tank flushing device, which flushes the inner wall of the sewage tank A through the side wall flushing pipe 3, thereby removing dirt on the inner wall of the sewage tank A, and scrapes the bottom of the sewage tank A through the scraping mechanism, thereby removing dirt deposited at the bottom of the sewage tank A. There is no need to arrange cleaning personnel to enter the sewage tank A for cleaning. Under the premise of ensuring the normal operation of the sewage tank, the labor intensity of the cleaning personnel is reduced.

The water inlet pipe 10 is connected to the water supply pipeline on the ship through the single-sided seat plate 9, thereby supplying water to the main water pipe 2.

[0054] In a specific embodiment, Figure 5 As shown, the pipeline support 1 includes an angle steel 101, a U-shaped pipe clamp 102 and a nut 103;

[0055] One end of the angle steel 101 is welded and fixed on the sewage tank A, and the other end of the angle steel 101 is provided with a hole for installing a U-shaped pipe clamp 102. Both the main water pipe 2 and the valve flushing pipe 8 can be fixed on the angle steel 101 through the U-shaped pipe clamp 102 and the nut 103;
