Description

TECHNICAL FIELD

[0001] The present application relates to geological exploration hole measuring technology, and particularly to a geological exploration hole measuring device. BACKGROUND

[0002] In the process of geological exploration, the depth of the geological exploration hole usually needs to be measured.

[0003] At present, the depth of the geological exploration hole is usually measured by using a measuring rope with scales. When measuring, the end of the measuring rope is connected with a lead sinker, and then the lead sinker is put into the geological exploration hole, and the measuring rope is lowered, the lead sinker pulls the measuring rope to move to the bottom of the geological exploration hole, and finally the worker observes whether the lead sinker contacts the bottom of the geological exploration hole with naked eyes. When the lead sinker contacts the bottom of the geological exploration hole, the lowering of the measuring rope is stopped, and at this time, the scales of the measuring rope can be observed to determine the depth of the geological exploration hole.

[0004] In the actual measuring process, when the geological exploration hole is deep, the worker cannot directly observe the bottom contact of the lead sinker with naked eyes, and usually a too long measuring rope is first lowered into the geological exploration hole to ensure that the lead sinker contacts the bottom. Then the worker manually straightens the measuring rope. However, when straightening the measuring rope, if the straightening force is small, the lead sinker contacts the bottom of the geological exploration hole and the measuring rope is not completely straightened. If the straightening force is large, the measuring rope is completely straightened and the lead sinker is pulled to the top of the bottom of the geological exploration hole, that is, the lead sinker does not contact the bottom of the geological exploration hole, and thus it is inconvenient for the worker to judge whether the lead sinker contacts the bottom of the geological exploration hole and whether the measuring rope is straightened, and the measuring precision is prone to be inaccurate.
