[0023] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by technicians in the technical field of the present invention.
[0024] Example 1
[0025] like Figure 1-6 As shown, this embodiment is an inclination static level, including a level body 8 and an automatic balancing bracket, and the level body 8 is arranged on the automatic balancing bracket; the automatic balancing bracket includes a base 1, a connecting ring 4 and a movable seat 5, a pillar 2 is provided on the base 1, a U-shaped support plate 3 is provided on the top of the pillar 2, a first mounting hole 31 is provided on the top of the U-shaped support plate 3, the connecting ring 4 cooperates with the first mounting hole 31 through a first rotating shaft 41, and can be rotatably installed inside the U-shaped support plate 3; a second mounting hole 42 is provided on the connecting ring 4, and the movable seat 5 cooperates with the second mounting hole 42 through a second rotating shaft 51, and can be rotatably installed inside the connecting ring 4; an inclination sensor 6 is also provided on the automatic balancing bracket.
[0026] In this embodiment, there are two inclination sensors 6, which are respectively mounted on the first rotating shaft 41 and the second rotating shaft 51. The first rotating shaft 41 and the second rotating shaft 51 are kept perpendicular.
[0027] In this embodiment, the base 1 is an L-shaped flat plate with fixing holes provided therein. Bolts engaging the fixing holes can be used to secure the base 1 to the measurement point. The support 2 is removably fixed to the base 1, such as by a threaded connection.
[0028] In this embodiment, the outer contour of the connecting ring 4 is a regular octagon, and the inner contour is a circle. An adjustment mechanism 7 is provided on the connecting ring 4. This adjustment mechanism 7 is used to maintain balance between the connecting ring 4 and both sides of the first rotating shaft 41 during initial installation. The adjustment mechanism 7 comprises a screw 71 disposed on the outer side of the connecting ring 4, and a nut 72 attached to the screw 71. During adjustment, the center of gravity of the entire connecting ring 4 can be adjusted by simply rotating the nut 72 to displace it on the screw 71. Similarly, the same adjustment mechanism 7 can also be provided on the movable seat 5 to ensure the initial balance of the movable seat 5.
[0029] In this embodiment, the level body 8 adopts an existing liquid level type static level.
[0030] The inclination static level in this embodiment is used in the same manner as in existing methods. It can be fixed to the measuring point via an automatic balancing bracket. Its advantage lies in that inclination sensors 6 are provided on both rotating shafts of the automatic balancing bracket to respectively measure the inclination angles in the two rotating shaft directions, i.e., the inclination in the corresponding directions at the measuring point. Furthermore, the automatic balancing bracket ensures that the level body 8 remains horizontal at all times, thereby ensuring that the movement direction of the float inside the liquid-level static level body 8 remains vertical. This allows the float's vertical movement to more accurately reflect the settlement of the measuring point, thereby improving measurement accuracy.
[0031] The above are only some embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have combinations and variations of the aforementioned technical features. Without departing from the spirit and scope of the present invention, those skilled in the art can improve, modify, or replace the present invention with equivalents, or apply the structure or method of the present invention to other fields to achieve the same effect, which all fall within the scope of protection included in the present invention.
