Description

Technical Field

[0001] This utility model relates to the field of earthwork excavation technology, and in particular to a device for accurately detecting the slope of riverbed earthwork excavation. Background Technology

[0002] Earthwork excavation is a crucial process in the initial stages and throughout the construction of a project. It involves loosening, breaking, excavating, and removing soil and rock. Based on the properties of the soil and rock, earthwork excavation is divided into earth excavation and rock excavation. Earthwork excavation is also classified according to the construction environment—open-air, underground, or underwater—into open-cut, tunnel, and underwater excavation. In hydraulic engineering, earthwork excavation is widely used for site leveling and slope cutting, foundation excavation for hydraulic structures (sluice gates, dams, spillways, hydroelectric powerhouses, pumping station buildings, etc.), excavation of underground chambers (hydraulic tunnels, underground powerhouses, various horizontal tunnels, vertical shafts, and inclined shafts), excavation and dredging of rivers, canals, and ports, quarrying of filling materials, building stone, and concrete aggregates, and demolition of temporary structures such as cofferdams or masonry and concrete structures.

[0003] In the prior art, patent document with publication number (CN208586593U) mentions an earthwork excavation slope detection and control device, including a first support rod and a second support rod. Both the first and second support rods have U-shaped cross-sections, and their open sides are positioned close to each other. The two side walls of one end of the second support rod are rotatably connected to the two side walls of one end of the first support rod via a first rotating shaft. A second rotating shaft is located at the end of the inner cavity of the first support rod away from the first rotating shaft, and a support rod is rotatably connected to one end of the first support rod via the second rotating shaft. The support rod has a hollow structure, and its end away from the second rotating shaft is open. A telescopic rod is movably connected to the support rod through the opening. In this prior art, the entire measuring device can be retracted into a long strip structure, making it easy to carry. Furthermore, during use, the angle formed by the support rod and telescopic rod with the first support rod can be freely adjusted within the range of 0-90 degrees, meeting the needs of earthwork excavation with different slopes. The adjustment method is simple and convenient, making it suitable for widespread use.

[0004] However, the existing technology described above is difficult to maintain a stable angle between the first support rod and the telescopic rod, which affects the measurement accuracy. Utility Model Content

[0021] In this specific embodiment, the connecting mechanism is disposed between the first rotating plate 1 and the second rotating plate 2. The central shaft 6 is rotatably connected to the first rotating plate 1 and the second rotating plate 2, and passes through the first rotating plate 1 and the second rotating plate 2. One end of the first rotating plate 1 and the second rotating plate 2 are respectively provided with a first cavity and a second cavity. The limiting shaft 7 is fixedly connected to the central shaft 6 and is located inside the cavity. A plurality of protrusions 8 are fixedly connected to the limiting shaft 7 and are evenly disposed on the outside of the limiting shaft 7. The spring 9 covers the surface of the central shaft 6 and is located on the limiting shaft 7. On one side, both the first cavity and the second cavity are adapted to the protrusions 8. The first rotating plate 1 is placed horizontally above the earthwork. The central shaft 6 is pressed, and the central shaft 6 drives the limiting shaft 7 to move, so that several of the protrusions 8 extend into the interior of the first rotating plate 1. The second rotating plate 2 is rotated, so that the second rotating plate 2 is pressed against the slope of the earthwork. The central shaft 6 is released, and the spring 9 pushes the limiting shaft 7, so that the protrusions 8 extend into the interior of the second rotating plate 2, fixing the positions of the first rotating plate 1 and the second rotating plate 2, improving stability and facilitating measurement.

[0022] The two ends of the connecting shaft 10 are rotatably connected to the first rotating plate 1 and the second rotating plate 2 respectively, and are located between the first rotating plate 1 and the second rotating plate 2.

According to the indication of the level 3, the threaded rod 16 is rotated, which drives the second support leg 15 to move, adjusting the first rotating plate 1 to a horizontal state. The central shaft 6 is pressed, which drives the limiting shaft 7 to move, causing several protrusions 8 to extend into the interior of the first rotating plate 1. The second rotating plate 2 is rotated, causing the second rotating plate 2 to press against the slope of the earthwork. The central shaft 6 is released, and the spring 9 pushes the limiting shaft 7, causing the protrusions 8 to extend into the interior of the second rotating plate 2, fixing the positions of the first rotating plate 1 and the second rotating plate 2. The pointer 12 rotates accordingly, pointing to the corresponding scale 13, which corresponds to the included angle between the first rotating plate 1 and the second rotating plate 2, i.e., the slope of the earthwork.
