[0028] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments. Embodiment 1

[0029] As Figure 1-2 shown, a marine seacock valve structure includes an outer hull plate 1, a seacock 11 is opened on the outer hull plate 1, several fixed plates 12 are installed on the inner side edge of the seacock 11, fixed studs are fixedly arranged on the fixed plates 12, and fixed nuts are threadedly connected to the fixed studs. A grille cover 13 is installed in the seacock 11, perforations are opened at the relative positions of the grille cover 13, and the grille cover 13 is detachably installed on the fixed plate 12 through the fixed nuts.

[0031] One open side of the seawater tank 3 is installed inside the outer hull plate 1 of the ship, and the sea valve 11 is located inside the seawater tank 3;

[0032] The seawater tank 3 is provided with mounting holes, the water inlet pipe head 31 is fixedly arranged in the mounting holes, and one end of the water inlet pipe head 31 extends out of the mounting holes and extends to the outside of the seawater tank 3.

[0033] The lower end flange of the seawater pipe 6 is connected with a connecting pipe 5. The upper end of the water inlet pipe head 31 is provided with a first external thread, and the lower end of the connecting pipe 5 is provided with a second external thread. The water inlet pipe head 31 and the connecting pipe 5 are vertically aligned. The lower end of the connecting pipe 5 is threadedly connected with a compression sleeve 4. The lower end of the compression sleeve 4 is provided with a flange 41. When the compression sleeve 4 is rotated downward, there is at least one position where the flange 41 contacts the seawater tank 3.

[0034] A sea valve 61 is installed on the seawater pipe 6, and the other end of the seawater pipe 6 is connected to the pipeline of the ship's cooling water.

[0035] The flow guide block 2 is arranged on the outer hull plate 1 behind the sea valve 11, and the flow guide block 2 is in an inclined shape with the front higher than the rear.

[0036] When the ship floats on the water surface, seawater enters the seawater tank 3. Open the sea valve 61 and start the seawater pump. The seawater sequentially passes through the water inlet pipe head 31 and the connecting pipe 5 and flows into the seawater pipe 6. The grid cover 13 can block larger sea organisms and impurities from entering the seawater tank 3. Smaller sea organisms and impurities will gradually accumulate in the seawater tank 3 and the water inlet pipe head 31. Therefore, it is necessary to clean them regularly. At this time, only the connecting pipe 5 between the seawater pipe 6 and the water inlet pipe head 31 needs to be removed. By rotating the compression sleeve 4 upward, the water inlet pipe head 31 and the connecting pipe 5 are separated, and then the connecting pipe 5 is removed, and the water inlet pipe head 31 can be cleaned, and the operation is simple; in addition, a flow guide block 2 is arranged outside the sea valve 11. When the ship is sailing, the seawater flows from front to back.

A plurality of brushes 73 are provided on one side of the U-shaped bracket 72 close to the filter cover 32.

[0041] The filter cover 32 provided in the seawater tank 3 can prevent smaller impurities from entering the connecting pipe 5. When the ship is sailing, it drives the rotating vane plates 71 at the lower end of the rotating shaft 7 to rotate, and then drives the U-shaped bracket 72 to rotate around the filter cover 32, and uses the brushes 73 to clean the impurities attached to the outside of the filter cover 32, avoiding blockage of the filter cover 32 and affecting the seawater flow rate. At the same time, it saves the trouble of manual cleaning and is time-saving and labor-saving. Embodiment 3
