Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gradienter, specifically is a gradienter of water conservancy and hydropower investigation. BACKGROUND

[0002] The gradienter is a device for measuring the gradient, which can help engineers accurately understand the changes of the terrain and topography, especially the gradient conditions of key parts such as the dam and slope, so as to facilitate engineers to develop a reasonable design scheme according to the actual situation.

[0003] The patent with the authorized announcement number CN219223729U discloses a gradienter for water conservancy and hydropower investigation, which comprises a gradienter main body, a measuring cavity and a handle. The measuring cavity is arranged on one surface of the gradienter main body and is in the form of an annular groove. The handle is welded to one side of the gradienter main body. A scale disc is embedded on one surface of the gradienter main body. The scale disc is provided with a through hole on one surface. The position of the through hole is adapted to the position of the measuring cavity. A disc is embedded in the measuring cavity. A large gear is embedded on the circumferential surface of the disc. A small gear is engaged with one side of the large gear. The small gear is cooperated with an adjusting knob on the circumferential surface. The disc is rotatably connected with the measuring cavity. A level is embedded in the disc. The level is movably connected with the disc. The positioning rod and the connecting spring structure facilitate the installation and disassembly of the level, so as to facilitate the disassembly and replacement of the level when it is damaged, facilitate the subsequent use of the device and improve the work efficiency of the operator.

[0004] However, the following problems still exist in the use of the current gradienter:

[0005] When using the gradienter, the measurement data needs to be recorded, and after the measurement is completed, the gradienter needs to be put down for recording. In order to ensure the measurement accuracy, multiple measurements need to be performed near the same position. At this time, the measurement and recording need to be repeatedly picked up and put down, which is very time-consuming and laborious and affects the measurement speed. In addition, when using the gradienter, the bottom of the gradienter is directly in contact with the dam and slope for measurement. Since the area of the bottom of the gradienter is small, recesses are easily formed on part of the dam and slope during measurement. Since the bottom of the existing gradienter is in the form of a whole square structure, the position of the lower end of the gradienter is inclined due to the recess, and inaccurate measurement is easily caused.
