[0029] Working principle:

[0030] When sewage treatment of hydrogen energy ships is required, workers introduce the sewage on the hydrogen energy ship through the water inlet 6 onto the filter plate 7. The impurities in the sewage of the hydrogen energy ship are larger than the grid, so they will be blocked by the grid and stored on the filter plate 7, while the sewage of the hydrogen energy ship will pass through the grid and be introduced into the box body 1. Through the above method, the sewage of the hydrogen energy ship is filtered. After the sewage of the hydrogen energy ship is filtered, use an external sealing plug to seal the two water inlets 6, connect the external power supply of the heating plate 11 and start it. The heating plate 11 gradually increases the temperature and transfers the heat to the sewage of the hydrogen energy ship in the box body 1, thereby heating and sterilizing the sewage of the hydrogen energy ship. During the heating process of the sewage of the hydrogen energy ship, the pressure relief valve 12 can be opened to discharge the air pressure in the box body 1 outside the box body 1 to prevent the internal air pressure of the box body 1 from being too high. Through the above method, high-temperature sterilization work is carried out on the filtered sewage of the hydrogen energy ship. After the sewage of the hydrogen energy ship is sterilized, turn off the heating plate 11, and then open the water outlet 8 through the valve. The sewage of the hydrogen energy ship will be discharged outside the box body 1 through the water outlet 8, and then workers can use an external box to collect it;

[0031] After the sewage of the hydrogen energy ship is discharged outside the box body 1, connect the external power supply of the servo motor 302 and start it. The servo motor 302 drives the first gear 303 to rotate, and the first gear 303 drives the second gear 304 to rotate (the rotation directions of the first gear 303 and the second gear 304 are opposite), thereby causing the two rod bodies 305 to swing inward. The two rod bodies 305 drive the vertical plate 306 to move through the chute, thereby causing the cross bar 309 to move. The cross bar 309 drives the vertical block 10 to move (the movement mode of the right vertical block 10 is the same as that of the left vertical rod 10). The two vertical rods 10 move inward. During the movement of the two vertical rods 10, the rubber scraping layers at the lower ends of the two vertical rods 10 push the residual sewage of the hydrogen energy ship on the inner wall of the box body 1 to the water outlet 8 and discharge it outside the box body 1 (the working mode of the rubber scraping layer is similar to that of an automobile windshield wiper). After the residual sewage of the hydrogen energy ship is discharged outside the box body 1, reverse the two servo motors 302 according to the above method to reset the positions of the two vertical blocks 10. After the positions of the two vertical blocks 10 are reset, turn off the two servo motors 302. Through the above method, the residual sewage of the hydrogen energy ship on the inner wall of the box body 1 is discharged from the box body 1. Through the above method, the treatment work of the sewage of the hydrogen energy ship is completed;

[0032] When the filter plate 7 needs to be cleaned, turn the handle 202 clockwise. The handle 202 drives the rotating shaft 201 to rotate, and the rotating shaft 201 drives the vertical rod 203 to rotate. At this time, the torsion spring 204 forms a torque. Stop turning the handle 202 after the vertical rod 203 is separated from the filter plate 7. The limit on the position of the filter plate 7 is cancelled in the above way. Then take out the filter plate 7 from the box body 1. After the filter plate 7 is taken out from the box body 1, release the handle 202. According to the above way, the torsion spring 204 releases the torque to drive the vertical rod 203 to reset. Then clean the filter plate 7. After the filter plate 7 is cleaned, put the plate body 7 back into the box body 1 for reset. Then limit the position of the filter plate 7 again according to the above way to limit the plate body 7 in the box body 1 again. The cleaning work of the filter plate 7 is completed in the above way.
