Embodiment：
A kind of high-accuracy water leveling ruler calibrating installation based on sine, as shown in figure 1, by detection platform 1, pedestal 3, detection platform 1 is connected at one end through rotary shaft 5 with pedestal, and surrounding is four levelling foots 7 below the pedestal, and the levelness of detection platform 1 and pedestal 3 can be adjusted.Detection platform 1 can be to be rotated upwardly and downwardly by rotary shaft 5；The other end of detection platform 1 and pedestal 3 is connected by adjusting nut 6, and rotation adjusting nut 6 can rotate upwardly and downwardly detection platform；Side close to adjusting nut in the detection platform is fixed with displacement transducer 2, the upper surface of the gauge head contact pedestal 3 of displacement transducer 2, the measuring staff axial line distance of displacement transducer 2 1m away from the axle center of rotary shaft 5.
Detection platform 3 is fixed on by screw for fixed tested horizon rule pressing plate and support 4, gauge 11 as shown in Fig. 2 having in the detection platform 1, there is air level 10 at the middle part of detection platform 3, and the detection platform 3 is locating piece 8 close to the side of rotary shaft 5；
As shown in Figures 3 and 4, accessory has 45 ° of locating rods and 90 ° of location-plates, has screw 13 in detection platform side, and for the fixation of 45 ° of locating rods 14, there is screw 16 detection platform and pedestal side, the fixation for 90 ° of location-plates 15.
As shown in fig. 6, displacement transducer 2 can be connected by data wire 17 with computer 18.
The mode that the present invention is used for horizon rule calibrating is as follows：
(1) leveling of the invention
Such as Fig. 3, during use, first adjust levelling foot 7, rotating adjusting nut 6 again, until the spirit bubble 10 in detection platform 1 is stable in center, it is ensured that the level of itself of detection platform 1, then displacement transducer 2 is returned to zero, tested horizon rule 12 is placed on horizon rule calibrating installation afterwards, the side of horizon rule is critical to lean on locating piece 8, is finally fixed with pressing plate 4.
