Description

Water supply well is used flow sensor
Technical field
The present invention relates to a kind of measurement water flow, the isoparametric sensor of flow velocity.Specifically a kind of water supply well is used flow sensor.
Background technology
The IT application to agriculture management of China also is in the starting stage, and the automaticity of field irrigation is also very backward with management, also is in manually-operated traditional approach for a long time.At present; The 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 for mounted pipeline in the requirement of reinstalling the flow water meter, and the scene is difficult to satisfy condition sometimes, and later maintenance cost is high.Especially aspect the data statistics of farmland irrigation water amount, almost has no 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 under the environment of agriculture water supply well, use.
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 is high.
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 are convenient, measure accurately water supply well uses flow sensor.
Realize that above-mentioned purpose adopts following technical scheme: a kind of water supply well is used flow sensor, and the sensor body that comprises sensor outer housing and be installed in enclosure also comprises connecting pipe nipple, impeller and impeller support; Said sensor body is a non-magnetic sensor, and this non-magnetic sensor is provided with the chip that is used for pulse signal and serial data conversion output; Said connection pipe nipple is arranged on the two ends of sensor outer housing through 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 said 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 the calculating and the management of the complicacy 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
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Referring to accompanying drawing 1-8, in the present embodiment, this water supply well is used 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 a non-magnetic sensor; It is installed in the groove on sensor outer housing 1 circumference; This non-magnetic sensor is provided with the chip that is used for pulse signal and serial data conversion output, and this chip is used for commutation pulse signal and serial data, and it can be exported simultaneously.Connect pipe nipple 9 is arranged on sensor outer housing 1 through the high-strength bolt as web member two ends.The impeller support comprises the cradling piece 2 and 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 a 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 are spent with 60, can tell the rotating of impeller blade like this.At least be provided with three blades on the impeller, section type of the being wing-shaped structure of blade 6.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, promptly can directly insert the pipeline of being installed, and pipe flange connects fixing 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, and wherein the blade coordinate has certain scope, is example with the blade of impeller on the DN80 pipeline; Its coordinate range shown in accompanying drawing 9, and according to the blade shape that key point constituted of this coordinate range shown in accompanying drawing 10.Blade adopts formed type of 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 interior inserting adds the formula syndeton, can be installed on the pump pipeline first or that level perhaps vertically is provided with arbitrarily.Pipeline inserts pipeline with being connected directly of this sensor through pipe nipple, and pipe flange connects fixing getting final product to folder, has solved when install the working-yard to change original pipeline configuration and complicated cutting welding sequence.The present invention adopts is no magnetic, untouchable sensor wheel speed, like this can the effectively preventing magnetic medium to the interference of its generation, the precision of raising flow metering.
