Method for remotely measuring river flow or channel flow on line and special tracking flow rate measurement device

Abstract

The invention relates to a method for remotely measuring river flow or channel flow on line and a special tracking flow rate measurement device, and belongs to the technical field of perpendicular measurement of river or channel flow rate, on-line remote measurement of flow rate, flow metering and data remote transmission. The technical scheme is that: the device comprises a suspension cable (1) and a tracking ship (2), wherein the suspension cable is arranged on water surface of the river or channel; the tracking ship can move along the suspension cable and float on the water surface; the tracking ship is connected with the suspension cable through two parallel adjustable connecting rods; because the two connecting rods (13) are kept in parallel, the distance from the tracking ship to the suspension cable is ensured to be equal all through; and the tracking ship is provided with a flow rate measurement system, a driving system, a power supply system, a control system and a data acquisition and transmission system. The method and the device have the advantages that: (1) each part of the invention can be manufactured in factories in batches and is very convenient to install at site; (2) situ manual control can be realized by using a wireless handheld parameter instrument and automatic acquisition and remote transmission can also be realized; (3) a solar cell is used for supplying power, so that the method and the device are fully suitable for outdoor environment; and (4) the device can be disassembled together with a supporting rod and a steel cable at the end of water discharge so as to prevent damage and loss.

Description

Technical field: [0001] The invention relates to a method for telemetry and on-line measurement of river or channel flow and a special-purpose navigating flow velocity measuring device, belonging to the technical fields of measurement of flow velocity of river or channel, on-line telemetry of flow velocity, flow measurement and remote data transmission. Background technique: [0002] At present, the current measurement methods for the flow of wider rivers or channels mostly use the velocity area method, and the methods and equipment used mainly include the following three types: ①Hand-held propeller velocity meter, through the hand-held propeller velocity meter, point by point according to different depths Carry out manual measurement; ②Sling-type current meter, install slings at both ends of the river or channel, hang the current meter on the sling, set traction, driving, and manipulation mechanisms on the shore, and let people control the current meter on the sling point by...

AI Technical Summary

Problems solved by technology

The above three methods cannot be operated on site without human beings, and cannot realize long-term online automatic detection of flow velocity; the V-ADCP Doppler profile velocity meter is not only expensive, generally 300,000 yuan, but also affected by the sediment content of the measured water, Cannot be used in most yellow irrigation areas

In addition, long-term automatic detection of traffic in the field requires someone to be on duty, but it is a waste of manpower and material resources, and it is difficult to realize; if no one is on duty, the problem of anti-theft is always a problem that plagues those skilled in the art
