A precision welding method for a new energy ship hull, which is applied to a new energy ship hull according to any one of claims 1 to 9, characterized in that: The welding method steps are as follows: Step 1: According to the measurement in advance, the strip plugs (74) are welded on both sides, front side and rear side of the inner cavity of the battery storage compartment (2), and then the strip steel plate (61) is welded to the bottom of the inner cavity of the new energy ship (1), and the movable seat (62) is put on the surface of the slide seat (610), and then the steel plate spring (64) is put on the surface of the steel column (63) on the two horizontal movable seats (62), and then the gasket nut (66) is tightened on the steel column (63), and then the steel frame (3) and the column (4) are placed on top of the four steel plate springs (64), and the steel plate spring (64) is moved so that the movable seat (62) is ) moves on the surface of the slide seat (610), so that the steel leaf spring (64) is aligned with the crossbeam on the steel frame (3), and then the fastening bolt (612) is screwed, so that the fastening bolt (612) moves downward due to the thread, and then the fastening bolt (612) is pressed against the slide seat (610), and then the movable seat (62) is fixed on the strip steel plate (61), and a U-shaped clamp (67) is put on the surface of the steel leaf spring (64) and the steel frame (3), and then the sleeve (68) is put on and the washer nut (69) is tightened, so that the steel leaf spring (64) and the steel frame (3) are fixed; Step 2: Lay the porous elastic plate (9) on the top of the steel frame (3), and then connect it to the circular hole (82) on the top fixing plate (81) of the battery body (5) by a forklift or a lifting device. Then, lift the battery body (5) to the top of the steel frame (3) and place it on the top of the porous elastic plate (9). Remove the device in the circular hole (82), then pick up the connecting block (89) and the limiting plate (810), pass through the circular hole (82), and then put the limiting plate ( 810) is aligned, and then the threaded column (84) is operated to rotate. Due to the thread, the moving block (85) moves downward in the inner cavity of the fixed frame (83), and the moving block (85) drives the pulling plate (86) to move downward. The pulling plate (86) pulls the connecting block (89) and the limiting plate (810) through the steel chain (88) until the steel chain (88) is tightened and the limiting plate (810) is against one side of the fixed plate (81), so that the battery body (5) can be fastened to the steel frame (3); Step 3: Pick up the vertical plate (71), push the movable plate (73) toward the vertical plate (71) and compress the spring (72), reduce the distance between the movable plate (73) and the vertical plate (71), and then make the strip slot (75) on the vertical plate (71) fit on the strip plug (74) until the vertical plate (71) completely enters the inner cavity of the battery storage compartment (2), cancel the pressure on the movable plate (73), and the restoring force of the spring (72) makes the movable plate (73) press against the outer side of the column (4), and move the vertical plates on the four sides. (71) are all installed in this way. The side protection components (7) on the four sides of the battery body (5) and the four lower protection components (6) at the bottom of the battery body (5) protect the battery body (5). The battery body (5) is protected, thereby preventing the battery body (5) from shaking and hitting the side of the battery storage compartment (2) due to the movement of the new energy ship (1), thereby preventing the battery body (5) from being damaged by collision, ensuring the safety of the battery body (5) and extending the service life of the battery body (5).
