Abstract
The utility model discloses a measure sensor device of rotation type shower nozzle rotating characteristic and rotational speed, including installing the disc on the shower nozzle base of rocking arm formula shower nozzle, evenly be fixed with several tongue tube or hall switch on the disc, and fix the cantilever on the shower nozzle body of rocking arm formula shower nozzle, install the magnet steel on the cantilever, make the equipartition at shower nozzle several tongue tube or hall switch all around closed in proper order at the pivoted in-process through the magnet steel of fixing on the shower nozzle body, send pulse signal, can reach the measurement to shower nozzle rotating characteristic and rotational speed through the measurement to pulse signal time interval. The utility model has the advantages of being scientific and reasonable in design, simple structure has overcome existing rotation type shower nozzle tachometer and can not rotate the shortcoming that the adversion variable property of round carries out the measurement to the shower nozzle rotating characteristic and rotational speed to the shower nozzle in the shower nozzle is experimental.
Description
One, affiliated technical field
The utility model belongs to a kind of improvement of existing rotating sprinkler rotation-speed measuring device, relates to a kind of sensor of sprinkling irrigation with rotating sprinkler rotational characteristic and rotating speed that be used to measure.
Two, background technology
Sprinkler irrigation technique has played huge impetus as a kind of advanced person's water-saving irrigation technique to the development of world agriculture.Shower nozzle is one of critical component of spray irrigation system, and the quality of its performance will directly influence the quality of system.So each state all drops into a large amount of energy on the experimental study of shower nozzle and improvement in performance.Rotating sprinkler is to adopt one of maximum shower nozzle in the present sprinkler irrigation technique, and its rotational characteristic and rotating speed are one of principal elements that influences its performance, so its measurement becomes one of main task in the sprinkler performance experimental study.
The sensor of existing measurement rotating speed is more, but the sensor that is applied to separately spray with rotating sprinkler rotational characteristic and tachometric survey is seldom arranged.Existing at present sprinkling irrigation with adopting universal velocity gauge in the rotating sprinkler rotation-speed measuring device more.High-revolving measurement during these velocity gauges generally are applicable to is changeed to several thousand as the per minute hundreds of.Sprinkling irrigation is generally very low with the rotating speed of rotating sprinkler, and per minute has only several commentaries on classics, so these velocity gauges are on measurement range and be not suitable for.In addition, these velocity gauges can not be measured shower nozzle change in rotational speed characteristic in rotating a circle.
Three, summary of the invention
At defective or the deficiency that above-mentioned prior art exists, the purpose of this utility model is, provides a kind of being exclusively used in to measure the sensor device of sprinkling irrigation with the rotating sprinkler rotating speed.
To achieve these goals, the technical scheme that the utility model is taked is, this is used to measure the sensor of sprinkling irrigation with rotating sprinkler rotational characteristic and rotating speed, be characterized in, it comprises: a disk, disk is fixedly installed on the showerhead base of impact driven sprinkler, evenly is fixed with several tongue tubes on the disk, and the two ends of all tongue tubes are connected in parallel;
Also include a cantilever, cantilever is fixed on the sprayer body of impact driven sprinkler, and the end of cantilever is equipped with magnet steel.
Above-mentioned tongue tube can use Hall switch to replace.The number of tongue tube is 6～24.
Described magnet steel be positioned at each tongue tube directly over, closed under the effect of magnetic force with tongue tube 3, the conducting metering circuit is also sent pulse signal.
This sensor of the present utility model is very suitable for spraying and uses the test of low rotating speed of rotating sprinkler, and this sensor can be measured the change in rotational speed situation of shower nozzle in rotating a circle.This sensor adopts common material, and its cost can be reduced to 1/tens of existing velocity gauge, and can guarantee measuring accuracy, and is reliable and practical.
Four, description of drawings
Fig. 1 is rotating sprinkler rotational characteristic and rotational speed sensor device synoptic diagram.
Fig. 2 is the circuit connection diagram of rotating sprinkler rotational characteristic and speed probe and pick-up unit.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The sensor device that is used to measure sprinkling irrigation usefulness rotating sprinkler rotational characteristic and rotating speed of the present utility model, its technical characterstic is to have adopted tongue tube, in rotating process, make several tongue tubes that are distributed on around the shower nozzle closed successively by being fixed on magnet steel on the sprayer body, the conducting metering circuit, send pulse signal, the measurement by the pulse signal pick-up unit pulse signals time interval can reach the measurement to shower nozzle rotational characteristic and rotating speed.
Referring to Fig. 1 and Fig. 2, disk 2 is fixed on the showerhead base 1, evenly be fixed with several tongue tubes 3 on the disk 2, cantilever 4 is fixed on the sprayer body 5, magnet steel 6 is installed in the end of cantilever 4, magnet steel 6 be positioned at tongue tube 3 directly over, with tongue tube 3 certain interval is arranged, when the size in gap turned to directly over the tongue tube 3 can make magnet steel 6, tongue tube 3 closure under the effect of magnetic force was advisable.The two ends of all tongue tubes 3 are connected in parallel, and series connection inserts in the pulse signal pick-up unit 7.Shower nozzle is in rotation process, and the cantilever 4 and the magnet steel 6 that are fixed on the sprayer body rotate thereupon, and in the time of directly over magnet steel 6 turns to each tongue tube 3, tongue tube 3 is closed successively under the effect of magnetic force, and the conducting metering circuit is sent pulse signal.The time interval that the pulse signals that gets final product pulse signal pick-up unit 7 takes place measures, thereby determines the rotational characteristic and the rotating speed of shower nozzle.The requirement of how much depending on shower nozzle rotational characteristic measuring accuracy of tongue tube 3 quantity is generally 6 to 24.
Tongue tube described in the utility model can also replace with Hall switch.
The utility model is simple in structure, and is scientific and reasonable, economical and practical, dependable performance.Satisfying under the condition of measuring accuracy, having overcome existing rotating sprinkler tachometric survey instrumentation weight range does not conform to, can not rotate the shortcoming measured of rotation speed change characteristic in the circle to shower nozzle, real satisfy sprinkling irrigation with in the rotating sprinkler experimental study to the measurement purpose of rotational characteristic and rotating speed.
