Abstract

The utility model discloses a venturi automation water measuring device, relating to a device for measuring water flow in a water channel. The device is composed of a venturi water tank, ultrasonic water-level sensors, a computer and a monitor, wherein the venturi water tank is arranged in the water channel to divide the water channel into two parts; one of the two ultrasonic water-level sensors is arranged in the water channel wall in front of the water inlet of the venturi water tank, and the other ultrasonic water-level sensor is arranged in the tank wall of the venturi water tank; the two ultrasonic water-level sensors are respectively connected with the computer to collect and store data; and the monitor is connected with the computer. The working method of the device is as follows: when water in the water channel flows the venturi water tank, the water can generate certain drop. The two ultrasonic water-level sensors can measure out corresponding water level, and the computer calculates out the drop. Then, the flow speed and the flow of water are calculated out by the drop and are stored in the computer for looking up at any time. The device can measure the flow of the water channel in an all-weather and full-automatic mode, so the error is small, and manual duty is not needed.

Description

Venturi robotization water gaging device
Technical field
A kind of venturi robotization water gaging device relates to the device of measuring discharge in the water channel.
Background technology
At present current meter is adopted in the measurement of discharge in the water channel more.Since Plain Irrigation District final stage channel have flow little, change frequently, luffing is big, high concentration of sediment, many impurity, gradient are slow, adopts instantaneous delivery that current meter is surveyed to inquire into the existence of whole day flow than mistake.Workload is also very big, and automaticity is not high, and the peasant monitors difficult, introduces the more advanced water measure equipment of exploitation so be badly in need of research.
The utility model content
The purpose of this utility model provide a kind of can be automatically, the device of discharge in the measure water canal.
This device is made of venturi flume, ultrasonic water level sensor, computing machine and monitor; Venturi flume is built in the water channel, with the water channel separated into two parts; One of two ultrasonic water level sensors is contained in the preceding water channel wall of venturi flume water inlet, and another is contained in the cell wall of venturi flume; Two ultrasonic water level sensors link with computing machine respectively, are used for image data and storage, and monitor and computing machine link.
The method of work of this device is: when the water in the water channel flows through venturi flume, can produce certain drop.Two ultrasonic water level sensors can be measured corresponding water level, and by computing machine calculate drop.Then, calculate the flow velocity and the flow of water by drop, and be stored in the computing machine, in order to checking at any time.This device can carry out round-the-clock to the flow of water channel, full automatic measurement, thereby error is little, need not manually on duty.Data can be checked at any time.
Description of drawings
Fig. 1 is the schematic side view of this venturi robotization water gaging device;
Fig. 2 is the schematic top plan view of this venturi robotization water gaging device.
Embodiment
This device is made of venturi flume 3, ultrasonic water level sensor 1, computing machine 4 and monitor 5; Venturi flume 3 is built in the water channel 6, divides 6 one-tenth two parts with water channel; One of two ultrasonic water level sensors 1 is contained in preceding water channel 6 walls of venturi flume 3 water inlets, and another is contained in the cell wall of venturi flume 3; Two ultrasonic water level sensors 1 link with computing machine 4 respectively, are used for image data and storage, and monitor 5 links with computing machine 4; 2 is the water surface.

Claims (1)
