Device and method for measuring water depth

Abstract

The invention relates to the technical field of water depth measurement, and provides a measuring device and a measuring method for water depth. The measuring device comprises a diving part, a floating part, a hand-held control part, a measuring rope. The diving part sneaks into the depth of the water to control a travel direction and a travel distance by a corresponding remote control part; the floating part floats on the water; the hand-held control part is controlled by the measurer standing on the shore; the measuring rope extends from the hand-held control port, penetrates the floating port and is connected to the diving port; and the floating port floats on the water surface as the diving port travels to ensure that the floating port and the diving port are maintained in the same vertical direction. The water depth measuring device provided by the invention sneaks into the deep bottom of the water through the diving part, and drives one end of the measuring rope to reach the deepbottom of the water, the measuring rope penetrates the floating part floating on the water surface, and a distance of the measuring rope between the diving part and the floating part is the depth ofthe waters. In this way, the measurer can know the depth of the water by reading a water inlet distance of the measuring rope.

Description

technical field [0001] The invention relates to the technical field of water depth measurement, in particular to a water depth measurement device and measurement method. Background technique [0002] At present, in the course of various basic surveying and mapping field work, various large and small water bodies are often encountered, and their depths need to be measured. The traditional methods of measuring the depth of waters can be summarized into the following two categories: the first category requires the use of ships or other large water vehicles, supplemented by traditional surveying and mapping tools for measurement, and the inconvenience of carrying and manipulation of ships is relatively difficult Control will increase the complexity and inconvenience of surveying work and affect the safety of surveying and mapping work; the second category is to use manual launching operations for direct measurement, but due to the unknown underwater environment, it will affect t...

Problems solved by technology

[0004] However, this patent calculates the water depth by the difference between the water pressure at the measured point and the atmospheric pressure. The atmospheric pressure is different due to the difference in geographical location, which brings a certain error to the calculation of the water depth, resulting in inaccurate measurement results.
