At present, the conventional pit-flushing measurement comprises a direct observation method, a laser profiler observation method, a sonar observation method and a sounding floating ball observation method, wherein the direct observation method uses an image recording device to flush the pit shape, and generally adopts a camera, so that the image observation effect is realized when the water environment becomes turbid in the pit-flushing process; the laser profiler system is complex and has high cost; the sonar has high observation precision, but has higher requirement, complex system and high cost; the observation method of the sounding floating ball has poor measurement precision and is mainly used for large-scale pit-flushing measurement.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is, overcome the above-mentioned defect that prior art exists, provide a low cost, the simple operation, and easily accurate measurement dashes the hole form measuring apparatu that dashes of the interior form of hole.

The utility model provides a technical scheme that its technical problem adopted is: the pit punching form measuring instrument comprises a cover plate and supporting legs respectively arranged at four corners of the cover plate, wherein through holes are uniformly formed in the cover plate, and probes are movably inserted in the through holes; the probe can freely fall in the through hole, and the bottom end of the probe contacts the inner surface of the punching pit, so that the morphological characteristics of the punching pit, such as the diameter, the depth and the like, are recorded.

Furthermore, the diameter of the upper part of the through hole is slightly larger than that of the lower part of the through hole, and a fixing plug sleeved with the probe is clamped at the upper part of the through hole; when the fixing plug is pulled out of the through hole, the probe can freely fall down, and then the fixing plug is clamped in the through hole, so that the probe is fixed.

Further, the bottom of probe is provided with the button head, and the arcwall face contact through the button head dashes the pit internal surface, the degree of depth that can be more accurate this point of acquireing.

Further, the cover plate is evenly provided with a track groove, a base with an upper part connected with the scale is clamped in the track groove, the base can be clamped in the track groove and can translate in the track groove, and the height value of each probe can be approached and measured.

Furthermore, the track groove is a T-shaped groove, and the bottom end of the base is matched with the T-shaped groove.

Furthermore, the cover plate is composed of an upper cover plate and a lower cover plate which are mutually attached.

Furthermore, the track groove is composed of a plurality of transverse track grooves and a vertical track groove communicated with the transverse track grooves.

Further, the height of the probe is smaller than the sum of the heights of the scale and the support leg.

Furthermore, the bottom end of the supporting leg is provided with a foot pad, and the foot pad can enhance the stability of the supporting leg.

The using method comprises the following steps: the utility model is placed above the punching pit, the fixing plug is pulled out to lead the probe to freely fall, the fixing plug is tightly clamped in the through hole after the probe is stabilized, and then the probe is fixed, thus leading the form of the punching pit formed on the upper part of the probe to be kept unchanged; then moving the scale and measuring the displacement value of the probe; the displacement value of the probe, i.e., the depth of the punched pit, and the diameter of the punched pit can be measured from the gap and the number of the probes.

The utility model has the advantages that the form of the pit can be conveniently copied through the probe which can freely fall, then the probe is fixed through the fixing plug, the depth value of each probe can be accurately measured through the movement and measurement of the scale in the track groove, and the form characteristics such as the diameter and the depth of the pit can be very conveniently obtained; the device has the advantages of low cost, convenient operation, adjustable instrument specification, adaptability to different levels of pit flushing and wide application range.
