Namely, a measurement datum plane is constructed among the transition measurement position, the inlet end measurement position and the outlet end measurement position by utilizing the first bottom plate 1, the second bottom plate 2 and the third bottom plate 3, and the irregular position measurement between the inlet end measurement position and the outlet end measurement position is converted into the vertical dimension measurement, so that the measurement result is more accurate, meanwhile, the first laser is horizontally emitted by utilizing the first measuring device 11 arranged on one of the first bottom plates 1, and is contacted with one end, far away from the second bottom plate 2, of one of the second measuring devices 21 arranged on the second bottom plate 2, and the characteristic that the first laser can be stably transmitted in a long distance is adopted, so that the difficulty in long-distance measurement operation by utilizing a tape measure and the artificial measurement error are avoided, the laser measurement process is simpler, and the result is more accurate.

Of course, in other embodiments, the first rod 111 may also be distributed along a vertical direction, and the corresponding influence size (such as a vertical distance from the first laser measuring instrument 112 to the first base plate 1) may be removed during calculation, for example, when the first rod 111 is horizontally irradiated into the pump room and blocked by a wall, the first rod 111 may be disposed along the vertical direction, so that the first laser measuring instrument 112 mounted thereon can be irradiated into the pump room. Wherein a first laser gauge 112 for measuring the vertical distance between the first floor 1 and the water level in the basin is located directly above the water level. Specifically, according to the size of the pool and the installation position of the first bottom plate 1, the number of the corresponding first rods 111 can be increased or decreased reasonably, so that the first laser measuring instrument 112 can be located right above the water level, the measuring accuracy is improved, and when the number of the first rods 111 is multiple, the first rods 111 can be connected in series through mutual hinging. It is noted that the water level may be used to indicate the water inlet position of the pump during experimental measurements due to the small change in water level over a short period of time.
