Problems solved by technology
On the other hand, when the pressure sensor is used in the measurement of muddy water, the sensor probe part is also very easily blocked by sediment particles and fails
For high-precision, long-term measurement, the problems of time drift and temperature drift of the pressure sensor are also difficult to solve

The invention relates to a muddy water pressure measuring device, and belongs to the technical field of water conservancy measurement. The device mainly comprises a pressure measurement container, a pressure measurement probe, a hose, a pressure measurement pipe, a pressure measurement plate, a camera and a computer, wherein the pressure measurement container is used for accommodating to-be-measured muddy water; a pressure measurement hole is formed in the side wall of the pressure measurement container, and the pressure measurement probe is mounted in the pressure measurement hole; two ends of the hose are connected with the probe and the pressure measurement pipe respectively to form a communication pipeline used for accommodating clear water, and the clear water and the muddy water are isolated by a film in the pressure measurement probe; the pressure measurement pipe is perpendicularly fixed on the surface of the vertically mounted pressure measurement plate, and a chessboard pattern calibrating plate is attached to the surface of the pressure measurement plate; the camera is aligned to the liquid level of the clear water in the pressure measurement pipe and connected with the computer; the camera shoots the liquid level of the clear water in the pressure measurement pipe and returns an image to the computer in real time; and the computer calculates the pressure of the to-be-measured muddy water according to the height of the liquid level. The device can measure the pressure of muddy water in a high-accuracy, high-frequency and automatic manner, and the comprehensive measurement accuracy is higher than that of conventional pressure measurement equipment.
Description
technical field [0001] The invention belongs to the technical field of water conservancy measurement, in particular to a new device for measuring muddy water pressure. Background technique [0002] Pressure is the water pressure that water acts on per unit area, and it is one of the most basic characteristic variables to describe the movement of water. In the fields of engineering practice and scientific experiments, pressure is mainly obtained by theoretical calculation and measurement. Among them, theoretical calculation is only applicable to static homogeneous water bodies, while the pressure in moving or heterogeneous water bodies can only be obtained by measurement methods. [0003] The piezometric tube is the most widely used pressure measuring device in the field of hydraulic model tests. The device is based on the formula p=ρgh (ρ is the density of the water body to be measured, g is the acceleration of gravity, and h is the water depth of the point to be measured). ...
