Background technology
The IT application to agriculture management of China also is in the starting stage, and the automaticity of field irrigation and management are also very backward, also are in manually-operated traditional approach for a long time.At present, flow instrument on the market and the installation of conventional water meter need on-site cutting and welded pipe line or flange, and the installation site that precision prescribed ensures, very high in the requirement of reinstalling the flow water meter for mounted pipeline, and the scene is difficult to satisfy condition sometimes, the later maintenance cost height.Especially aspect the data statistics of farmland irrigation water amount, almost without any the device of metering and data statistics.Now, this conventional water meter exists short, shortcomings such as cost of investment is high, installation is complicated, later maintenance difficulty of life-span if use under the environment of agriculture water supply well.
In addition, in the central water conservancy working conference of Held in Beijing, have all proposed in file of central authorities in 2011 and 8 to 9 July in 2011 to implement the strictest water resources management water gaging in advance, China's water supply well dry point quantity is very big, if adopt existing flow instrument investment huge, and later maintenance cost height.
Summary of the invention
The present invention be directed to the defective that prior art exists, provide a kind of simple in structure, Installation and Debugging make things convenient for, measure water supply well flow sensor accurately.
Realize above-mentioned purpose by the following technical solutions: a kind of water supply well flow sensor, the sensor body that comprises sensor outer housing and be installed in enclosure also comprises connecting pipe nipple, impeller and impeller support; Described sensor body is non-magnetic sensor, and this non-magnetic sensor is provided with the chip for pulse signal and serial data conversion output; Described connection pipe nipple is arranged on the two ends of sensor outer housing by web member; The impeller support comprises cradling piece and the sleeve that fixes as one, and cradling piece is fixed on the sensor outer housing inwall; Impeller comprises impeller housing, blade and the impeller shaft that is fixed together, and described impeller shaft is connected with sleeve set, is connected with the rotating speed induction metal plate on the impeller housing.
Adopt technique scheme, compare with traditional flowmeter, cost of the present invention is low, install, debugging is simple to operation, not restricted by the site environment factor, saved the equipment input, convenient later maintenance has been saved required inputs such as human and material resources of later stage.Use the present invention, can conveniently simplify calculating and the management of the complexity that the flowmeter water meter brings, use easy to operate, the transmission of data; It is simple to operate that mounted pipeline increases flow device again, reduced the input of a large amount of material resources, manpower; Accurately grasp data messages such as the water yield.

Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-8, in the present embodiment, this water supply well flow sensor comprises sensor outer housing 1 and the sensor body that is installed in enclosure, also comprises connecting pipe nipple 9, impeller and impeller support.Sensor body is non-magnetic sensor, it is installed in the groove on sensor outer housing 1 circumference, this non-magnetic sensor is provided with the chip for pulse signal and serial data conversion output, and this chip is used for commutation pulse signal and serial data, can reach output simultaneously.Connect pipe nipple 9 is arranged on sensor outer housing 1 by the high-strength bolt as web member two ends.The impeller support comprises cradling piece 2 and the sleeve 3 that fixes as one, and cradling piece 2 is fixed on sensor outer housing 1 inwall.Impeller comprises impeller housing 5, blade 6 and the impeller shaft 7 that is fixed together, and impeller shaft 7 is connected with sleeve 3 suits, is connected with the rotating speed induction metal plate on the impeller housing 5.Cradling piece 2 is that the cross section is leg-of-mutton rod-like structure.The rotating speed induction metal plate is convex structure, at least be connected with two these sheet metals on each impeller housing, sheet metal in the present embodiment comprises big sheet metal 4 and lamellule 8, and their arc angles of two are that 120 degree and 60 are spent, and can tell the rotating of impeller blade like this.At least be provided with three blades on the impeller, the section of blade 6 is the class wing-shaped structure.The width of blade 6 is made according to actual conditions, makes this sensor can be applicable to the flow metering of pipelines commonly used such as DN50, DN80, DN100, DN150, DN200 at least.This flow sensor is arranged on pump head, also can be arranged on the pipeline of any level or vertically placement.The pipe nipple at these flow sensor two ends is plugged in pipe interior, namely can directly insert the pipeline of installing, and pipe flange is connected and fixed this flow sensor to folder.
The class wing-shaped structure of described blade, it is the shape of the similar airfoil formed according to the numerous key points that experiment draws, the blade that is fit to the pipeline of each bore all has maximum outline and minimum outline, wherein the blade coordinate has certain scope, blade with impeller on the DN80 pipeline is example, its coordinate range as shown in Figure 9, and the blade shape that constitutes according to the key point of this coordinate range is as shown in Figure 10.Blade adopts the formed class wing-shaped structure of this coordinate range, and the string of a musical instrument of blade becomes 44.55 degree angles with the center line of impeller, guarantees that pipeline mean flow rate and wheel speed are strict linear relationship, more can measure flow accurately.
What this sensor adopted is that interpolation adds the formula syndeton, and it is first or arbitrarily on level or the pipeline that vertically arranges to be installed in pump.Pipeline inserts pipeline with being connected directly of this sensor by pipe nipple, and pipe flange is connected and fixed folder and gets final product, and has solved when install the working-yard to change original pipeline configuration and complicated cutting welding sequence.What the present invention adopted is that no magnetic, untouchable sensor detect wheel speed, like this can the effectively preventing magnetic medium to the interference of its generation, the precision of raising flow metering.
