Flow sensor for water source well

Abstract

The invention provides a flow sensor for a water source well, which comprises a sensor shell, a sensor body mounted at the inner part of the shell, connecting short sections, a vane wheel and a vane wheel bracket, wherein the sensor body is a nonmagnetic sensor; the connecting short sections are arranged at the two ends of the sensor shell through connecting pieces; the vane wheel bracket comprises a bracket rod and a sleeve which are fixedly connected to form a whole; the bracket rod is fixedly connected onto the inner wall of the sensor shell; the vane wheel comprises a vane wheel shell, vanes and a vane wheel shaft which are fixedly connected together; the vane wheel shaft is connected with the sleeve in a sleeved manner; and rotation speed induction metal sheets are fixedly connected onto the vane wheel shell. The flow sensor has low cost, is simple to mount and debug, is easy to operate and is not subjected to field environmental factors, the invested capital of equipment is saved, the later stage maintenance is convenient, later stage manpower and material resource input is saved, complex calculation and management brought along by a water meter of a flowmeter can be conveniently simplified, and service data can be easy to operate and transmit; and flow equipment is added to a mounted pipeline, the operation is simple, and material resource and manpower input is reduced;and water amount data information is accurately mastered.

Description

technical field [0001] The invention relates to a sensor for measuring parameters such as water flow and flow velocity. Specifically, it is a flow sensor for a water source well. Background technique [0002] my country's agricultural information management is still in its infancy, and the degree of automation and management of farmland irrigation is still very backward, and it has been in the traditional way of manual operation for a long time. At present, the installation of flow meters and traditional water meters on the market requires on-site cutting and welding of pipes or flanges, and requires a precision-guaranteed installation position. The requirements for reinstalling flow meters on already installed pipes are very high, and sometimes the site is very difficult. It is difficult to meet the conditions, and the maintenance cost is high in the later period. Especially in terms of data statistics of farmland irrigation water consumption, there is hardly any devi...

AI Technical Summary

Problems solved by technology

At present, the installation of flow meters and traditional water meters on the market requires on-site cutting and welding of pipes or flanges, and requires a precision-guaranteed installation position. The requirements for reinstalling flow meters on already installed pipes are very high, and sometimes the site is very difficult. Difficult to meet the conditions and high maintenance costs in the later period

Especially in terms of data statistics on farmland irrigation water consumption, there is almost no device for metering and data statistics

Now, if this kind of traditional water meter is used in the environment of agricultural water source wells, there are disadvantages such as short life, high investment cost, complicated installation, and difficult later maintenance.

[0003] In addition, the No. 1 Central Document in 2011 and the Central Water Conservancy Work Conference held in Beijing from July 8 to 9, 2011 both proposed to implement the most stringent water resources management and water quantity first, and the number of water intake points in my country's water source wells is extremely large , if the existing flow meter is used, the investment is huge, and the later maintenance cost is high
