Description

Technical Field

[0001] This utility model belongs to the field of measuring device technology, specifically a measuring device for wind power civil engineering measurement. Background Technology

[0002] During the civil engineering surveying process for wind power projects, it is necessary to measure the distance between the wind turbine bases so that the wind turbine bases can be installed at the specified distances, ensuring that the distance between adjacent bases is fixed and that they can work together. This requires the use of a measuring device for measurement.

[0003] Existing measuring devices have relatively complete structures and functions, and can meet basic usage requirements, but they still have the following problems:

[0004] In actual use, the measuring tape is prone to loosening during measurement. A loose measuring tape will result in an error in the measured distance, making the measurement result too large. This will lead to inaccurate measurement of the distance between the machine bases, affecting the interaction between the subsequent machine bases, which is very inconvenient. Utility Model Content

The two ends of the torsion spring 29 are fixedly connected to the second circular plate 28 and one of the trapezoidal plates 21, respectively. A limiting and leveling structure 3 is provided between the measuring tape 24 and the base 1. The limiting and leveling structure 3 includes a fixing plate 31. A rectangular through hole 32 is opened on one side of the fixing plate 31. The measuring tape 24 is inserted into the inner wall of the rectangular through hole 32. The measuring tape 24 can be inserted into the inner wall of the rectangular through hole 32, thereby limiting the measuring tape 24.

[0027] Specifically, such as Figures 2-4As shown, the other end of the rotating rod 22 is fixedly connected to a first circular plate 25. A threaded locking rod 26 is threadedly connected to one side of the first circular plate 25. A threaded locking hole 27 is opened on one side of another trapezoidal plate 21. The threaded locking rod 26 can cooperate with the threaded locking hole 27 to fix the first circular plate 25. A U-shaped plate 210 is fixedly connected to the top of the two trapezoidal plates 21. A sliding rod 211 is slidably connected to the top of the U-shaped plate 210. The bottom end of the sliding rod 211 is fixedly connected to... There is an arc-shaped pressure plate 212, and a sliding rod 211 can cooperate with the arc-shaped pressure plate 212 to limit the measuring tape 24. A circular block 213 is fixedly connected to the top of the sliding rod 211, and an operating handle 215 is fixedly connected to the top of the circular block 213. A spring 214 is sleeved on the outer surface of the sliding rod 211. The spring 214 allows the arc-shaped pressure plate 212 to fit against the measuring tape 24 on the winding roller 23.
