The invention provides a rowing machine capable of adjusting the angle of a water tank, which comprises an underframe 100 and the water tank 200, wherein the water tank 200 is hinged with the underframe 100 and the arrangement angle of the water tank 200 is adjusted through an angle adjusting mechanism.
In the technical scheme of the invention, through the research on the arrangement angle of the water tank, the difference of the resistance and the change thereof caused by the arrangement of the water tank at different angles is found, and the specific results are shown in table 1 and fig. 3:
TABLE 1
| Unit: NM | Level1 | Level 2 | Level 3 | Level 4 | Level 5 | Level 6 |
| Level of | 291 | 293 | 295 | 297 | 298 | 301 |
| Inclined at 45 ° | 383 | 385 | 388 | 390 | 393 | 395 |
| Is vertical | 420 | 427 | 432 | 450 | 471 | 513 |

Table 1 shows test data obtained by performing resistance tests on the water tank in a horizontal, inclined at 45 °, and vertical state, respectively, under the same motor rotation speed, water tank, impeller, and water volume.
According to table 1, it can be seen that under the conditions of the same motor speed, the same water tank and the same impeller, the resistance generated by the water bucket inclined by 45 degrees is 10% -13% higher than that generated by the water bucket horizontally placed; the resistance value generated by the vertically placed water bucket in the movement process is 10 to 13 percent higher than that generated by the water bucket placed at an inclination angle of 45 degrees;
meanwhile, as can be seen from the resistance change diagram in fig. 3, when the horizontally placed bucket moves, the rotation of the impeller drives the continuous centrifugal flow of water in the bucket, and under the action of inertia, the resistance is weakened after the first paddling operation; when the bucket which is inclined by 45 degrees and the bucket which is vertically arranged move, the gravity can lead water to the bucket bottom belt, so that the inertia effect is small, and the resistance value of the first rowing operation is basically kept unchanged.
