The seawater is screened and filtered by the screening mechanism, the water is guided by the guide plate 26, the sand and gravel in the water flow are blocked and collected by the collection trough 27, and the filter screen cylinder 13 is rotated to screw the threaded sleeve 14 into the inside of the first threaded groove 12.

[0030] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first screening section also includes a servo motor 21 fixedly installed on the top of the water filter tank 10. The output shaft of the servo motor 21 is fixedly connected to one end of a set of second rotating rods 22 via a coupling. The guide plate 26 has two sets of holes inside. The second rotating rods 22 are arranged between the three sets of guide plates 26. A pulley 24 is fixedly installed on the outer wall of the second rotating rod 22. A transmission belt 25 is sleeved between the two sets of pulleys 24. When the servo motor 21 is started, it drives the second rotating rod 22 to rotate. Through the two sets of second stirring plates 23 and the pulley 24, it drives another set of second rotating rods 22 to rotate, which in turn drives the second stirring plates 23 to rotate, thus stirring the water and improving the water filtration efficiency.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, the second screening section also includes a hole at the top of the filter cylinder 13, with an inlet 15 fixedly installed inside the hole. A first rotating rod 16 is rotatably installed on the top inner side of the filter cylinder 13. Three sets of fixing sleeves 18 are fixedly installed on the outer wall of the first rotating rod 16, and two sets of first fixing plates 19 are fixedly installed on the outer wall of the fixing sleeves 18. A first stirring plate 20 is fixedly installed at the bottom of the first fixing plate 19. Water is introduced into the interior of the filter cylinder 13 through the inlet 15. The rotation of the first rotating rod 16 drives the fixing sleeves 18 to rotate, and the first stirring plate 20 is fixed by the first fixing plate 19.

[0033] Example 2: Based on Example 1, specifically as follows... Figure 1 and Figure 5 As shown, four sets of filter screen plates 17 are fixedly installed inside the filter screen cylinder 13, with the top of each set of filter screen plates 17 in close contact with the bottom of the two sets of first stirring plates 20. The first stirring plates 20 clean and move the sand and gravel on the filter screen plates 17.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, three sets of openings are provided on one outer wall of the water filter tank 10. A first hinged door plate 29, a second hinged door plate 30, and a third hinged door plate 31 are respectively hinged and installed in the openings. Opening the first hinged door plate 29, the second hinged door plate 30, and the third hinged door plate 31 allows the impurities filtered out from inside the water filter tank 10 to be output.

[0035] Based on the above, the structure of the filter screen plate 17, the first stirring plate 20, the first hinged door plate 29, the second hinged door plate 30 and the third hinged door plate 31 achieves the purpose of rapid material discharge from the device, improves the filter material efficiency of the device, and enhances the flexibility of the device in use.

[0036] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 and Figure 4 As shown, a sealing plate 32 is provided on one outer wall of the water filter tank 10, and the outer wall of one side of the sealing plate 32 is fixedly connected to the outer wall of one side of the three sets of second fixing plates 28. The sealing plate 32 seals one outer wall of the water filter tank 10.

[0037] Specifically, such as Figure 1 and Figure 5 As shown, the holes in the four sets of filter screens 17 decrease in size from top to bottom, and one end of the first rotating rod 16 is connected to one end of a set of second rotating rods 22 via a coupling. This improves the filtration effect of seawater.

[0038] In summary, the structure of the water filter box 10, the first rotating rod 16, the water filter screen 17, the second rotating rod 22, the second fixing plate 28, and the sealing plate 32 achieves the purpose of sealing the device, connecting the internal parts of the device, improving the linkage effect of the device, and improving the stability of the device in use.

[0039] Working principle: Seawater enters the filter cylinder 13 through the inlet 15. The holes in the filter screen plate 17 gradually decrease in size from top to bottom to improve the filtration effect. The first rotating rod 16 rotates inside the filter cylinder 13, driving the first stirring plate 20 on the fixed sleeve 18 and the first fixed plate 19 to rotate. The first stirring plate 20 agitates the top of the filter screen plate 17, cleaning and agitating sand and other impurities on the filter screen plate 17 to prevent clogging. One end of the first rotating rod 16 is connected to one end of a set of second rotating rods 22 through a coupling to realize power transmission. Inside the filter tank 10, three sets of guide plates 26 guide the seawater, dispersing the water flow and slowing down the flow rate to facilitate subsequent screening. The collection trough 27 at the top of the guide plates 26 is used to collect larger impurities such as sand and gravel in the water flow. The servo motor 21 drives a set of second rotating rods 22 to rotate via a coupling. The second stirring plate 23 on the second rotating rod 22 stirs the seawater to improve the water filtration efficiency. Through the pulley 24 and the transmission belt 25, another set of second rotating rods 22 is also driven to rotate, realizing dual-shaft stirring. The seawater that has been initially stirred enters the filter screen cylinder 13 through the inlet 15. The four sets of filter screen plates 17 inside the filter screen cylinder 13 perform fine filtration of the seawater to remove finer impurities. The holes of the filter screen plates 17 decrease in size from top to bottom to improve the filtration effect. When it is necessary to clean the impurities inside the filter tank 10, the first hinged door plate 29, the second hinged door plate 30 and the third hinged door plate 31 can be opened for output. The sealing plate 32 seals one side of the outer wall of the filter tank 10 to prevent seawater leakage.
