[0017] The utility model provides a kind of water conservancy project deep hole inclination measuring device. With the following beneficial effects:

[0018] (1) After drilling and installing the deep hole casing, the operator places the support at the ground level above the borehole opening and places the liquid cylinder horizontally above the support, ensuring that the center of the liquid cylinder is basically aligned with the center of the borehole. Then, the positions of the weight, connecting line, and liquid cylinder are determined. The operator can then directly rotate the turntable, which drives the rotating rod and the winding roller to rotate. After the winding roller rotates, it will cause one end of the weight and connecting line to descend. Finally, the weight is slowly placed into the bottom of the hole, but does not touch the bottom, ensuring that the weight is in a free and suspended state. At this time, check whether the float in the liquid cylinder touches the wall of the liquid cylinder and exhibits a wall-sticking phenomenon. If a wall-sticking phenomenon occurs, adjust it in time. The relative position of the center of the connecting line and the center of the orifice is determined to ensure that the float is not in a free and non-adherent state. After a short while, once the float and the liquid cylinder are stable, the plumb line is established. The inclination of the hole is calculated using the angle deviation between the plumb line and the actual centerline of the formed hole (i.e., the axial line formed by connecting the center of the orifice and the center of the bottom of the hole). This principle can be used to correct the inclination of the drilled hole in a timely manner to ensure the verticality of the drilled hole. Then, the inclination angle is calculated using the formula: α = arctan(L / H). This solves the problem that some existing measuring devices have complex structures and require a lot of manpower and time to install and operate in deep holes, thus reducing measurement efficiency.

[0019] (2) When the operator needs to adjust the position of the connecting line and the counterweight to lower the device, the position of the limiting block can be moved. The limiting block will slide on the side wall of the positioning rod and squeeze one end of the compression spring. When the position of the limiting block moves downward and does not contact the side wall of the turntable, the operator can directly rotate the position of the turntable. By setting an auxiliary mechanism, the rotation of the turntable can be limited, thereby facilitating the operator to adjust the position of the connecting line and the counterweight and improving the performance of the device.
