A fixed maintenance device based on Doppler open channel flowmeter installation

Abstract

The invention relates to the technical field of agriculture, in particular to an installation, fixation and maintenance device based on a Doppler open channel flowmeter. The installation, fixation andmaintenance device comprises a bottom plate, wherein the upper surface of the bottom plate is fixedly provided with an outer shell, the middle portion of a rotating shaft is fixedly sleeved with a worm wheel, a rotating plate is installed on the upper surface of the outer shell, a clamping groove matched with the upper end of the rotating shaft is formed in the middle portion of the lower surfaceof the rotating plate, a lifting device is installed on the upper surface of the rotating plate, one end of the connecting rod is provided with a box base, one side of the ground is provided with anopen channel, a fixation member is installed on the upper surface of the box base by means of a bolt, a probe is installed between the fixation member and the box base, and a cleaning device is installed inside the box base. The installation, fixation and maintenance device has the advantages of being simple in structure and convenient to use, being capable of improving measurement precision, prolonging service life, being simple in operation, saving time and labor, greatly reducing labor intensity, having good use effect, and being worthy of popularization and use.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a fixed maintenance device based on Doppler open channel flowmeter installation. Background technique [0002] Doppler open channel (non-full pipe, underground channel) flowmeter is an ultrasonic flow meter that calculates the flow value by measuring the average flow velocity and liquid level (sectional area) of the liquid. With the rapid development of industry, agriculture and cities and the pollution of water resources, the gap of water that can be directly used is increasing. The channel flow measurement method is widely used and valued. [0003] When the existing flowmeter is installed and used, its surface is easily covered by silt, which reduces the measurement accuracy of the flowmeter and reduces the service life of the flowmeter. At the same time, the flowmeter is fixedly installed at the bottom of the open channel. , is inconvenient, time-consuming and labor-in...

Problems solved by technology

[0003] When the existing flowmeter is installed and used, its surface is easily covered by silt, which reduces the measurement accuracy of the flowmeter and reduces the service life of the flowmeter. At the same time, the flowmeter is fixedly installed at the bottom of the open channel. , is inconvenient, time-consuming and labor-intensive, and greatly increases the labor intensity. In view of the above situation, we propose a fixed maintenance device based on Doppler open channel flowmeter installation
