Depth measuring device

Abstract

The invention discloses a water depth measurement device, which belongs to the technical field of water depth measurement, and particularly relates to a water depth measurement device which is convenient to use and simple in structure. The water depth measurement device provided by the invention comprises a telescopic paying-off rod and a circular buoy plate, wherein the telescopic paying-off rod comprises an outer sleeve rod; a middle sleeve rod is arranged in the outer sleeve rod; an inner rod is arranged in the middle sleeve rod; a spool is arranged at the rear side part of the outer sleeve rod; a crank is arranged at the outer end of the spool. The water depth measurement device is structurally characterized in that a support rod is arranged on the rear end of the outer sleeve rod; a first guide roller is arranged on the support rod; a second guide roller is arranged on the middle part of the outer sleeve rod; a first line position adjustment element is arranged on the outer sleeve rod at the rear side of the second guide roller; a second line position adjustment element is arranged on the outer sleeve rod at the front side of the second guide roller; a third line position adjustment element is arranged at the front end of the outer sleeve rod; a fourth line position adjustment element and a third guide roller are arranged at the front end of the inner rod.

Description

technical field [0001] The invention belongs to the technical field of water depth measurement, in particular to a water depth measurement device. Background technique [0002] The rod scale that most people use to measure water depth at present has the following deficiencies. [0003] 1. It is inevitable that there will be deviation caused by inclination when directly placed and measured. [0004] 2. When the measurer cannot reach the position to be measured, the measurer cannot use the ruler to measure the water depth. [0005] 3. When the water level to be measured is too deep, the rod-type scale cannot be measured due to insufficient length, and it will cost more to prepare a longer scale. [0006] 4. Precision instruments such as sonar are expensive and bulky, and are not suitable for promotion and use among the general public. Contents of the invention [0007] The present invention aims at the above problems and provides a water depth measuring device which is ea...
