The invention discloses a device for measuring the flow in a gravity flow vertical pipe in real time. The device comprises a filling head, a measuring pipe arranged below the filling head and a single chip microcomputer, the back of the top of the filling head is hinged to a sealing cylinder through a hinge. The invention relates to the technical field of gravity flow measurement. According to the device for measuring the flow in a gravity flow vertical pipe in real time, a first telescopic rod is used for pushing an extrusion plate to accelerate gravity flow to flow into a flow guide pipe and a measuring pipe, and after the flow guide pipe and the measuring pipe are filled with a certain amount of gravity flow, a measuring plate directly cuts off the gravity flow in a filling head; the gravity flow in the flow guide pipe and the measuring pipe moves downwards under the action of gravity, the descending height of the gravity flow can be measured through the laser ranging module, the flow of the gravity flow can be obtained through calculation, non-contact measurement is achieved, the measurement result is more accurate, the flow of the gravity flow can be measured in real time, use is convenient, multiple sets of data can be conveniently obtained, and a more detailed data support is provided for the research of gravity flow.
Description
technical field [0001] The invention relates to the technical field of gravity flow measurement, in particular to a real-time flow measurement device in a gravity flow standpipe. Background technique [0002] The airflow and water flow caused by gravity are called gravity flow. The concept of gravity flow is non-Newtonian fluid, which is mixed and transported as a whole by sedimentary medium and sediment (also known as density flow and block flow, with large overall turbidity). The main method is transport (high-density fluid dispersed with a large amount of sediment). [0003] For the measurement of gravity flow flow, gravity flow sensor is usually used for measurement. This kind of setting method can only measure the position where the sensor is installed. Contact with gravity flow increases the resistance to gravity flow and affects the accuracy of flow measurement. For this reason, a real-time measurement device for flow in the vertical pipe of gravity flow is specially...
