Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, and specifically, to a measuring device for wind power generation construction. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electric energy. Utilizing wind power generation is very environmentally friendly, and the wind energy reserve is huge, so it has been increasingly valued by countries around the world. Before wind power generation construction, it is necessary to use measuring tools to measure the distance between each wind turbine to determine the installation position of the wind turbines. If the distance between two wind turbines is too small, they will affect each other. If the distance between two wind turbines is too large, it is not conducive to the utilization of land space.

[0003] After retrieval, the utility model patent with the publication number CN214149024U discloses a measuring device for wind power generation construction, including a housing and a tape measure. A square opening is installed at the upper part of the left end of the housing, and the square opening communicates with the housing. A winding wheel is arranged inside the housing, and a tape measure is wound around the outer surface of the winding wheel. A rotating shaft is arranged in the middle of the winding wheel, and the front end of the rotating shaft is rotatably connected to the inner wall of the housing. A micro motor is installed at the rear end of the housing, and the micro motor is fixedly connected to the rear end of the rotating shaft. One end of the tape measure is installed with a plug board, a stepping pedal is installed at the upper end of the plug board, a limiting board is sleeved on the outer surface of the plug board, and the limiting board is located below the connection between the tape measure and the plug board. An alignment board is vertically installed at the upper right part of the stepping pedal, a laser lamp is installed at the upper end of the housing, and several clamping blocks are sleeved on the outer surface of the square opening; this device is convenient to carry, and one person can complete the measurement task. One end of the tape measure is firmly fixed by the plug board to prevent the starting point from shifting during measurement and affecting the measurement result. The size is marked by the clamping blocks, which is convenient for recording data, fast and convenient, saving time and effort.

[0004] However, the above patent still has the following deficiencies: when the tape measure is stretched, the middle section of the tape measure will bend due to its own weight, affecting the measurement accuracy; and although the clamping blocks can mark the size, it is not convenient to record specific information at a suitable position. Therefore, we propose a measuring device for wind power generation construction. Content of the Utility Model
