Description
Technical field
The invention belongs to the Key experiments device in water-saving irrigation irrigation sprinkler head performance measurement, refer in particular to a kind of assay device that can accurately measure nozzle rotating angle.
Background technology
Sprinkling irrigation is the irrigation technique of a kind of advanced person, is widely used in recent years in the agricultural irrigation of countries in the world.Shower nozzle is the key equipment affecting quality of pouring water.Shower nozzle wide variety, relatively broad with the application of the rotating sprinkler such as impact driven sprinkler and fluidics sprinkler.The feature of this type of shower nozzle is, discontinuous rotation in rotary course, and the effect batch (-type) stepping being driven power rotates.Shower nozzle is in rotation process, and the step angle of shower nozzle is the important parameter weighing shower nozzle behavior in service, provides important evidence for studying size and the structure improvement etc. of shower nozzle driving force.But in existing measurement means, the measurement to shower nozzle step angle and rotation angle parameter the most well solves.Therefore, develop a kind of assay device that can accurately measure nozzle rotating angle and there is important Practical significance.
Through retrieval, currently without relevant document report.
Summary of the invention
It is an object of the invention to provide a kind of assay device that can accurately measure nozzle rotating angle, make shower nozzle in rotary course, it is possible to measure sprinkler rotation angle accurately.
The technical scheme that the present invention takes is: a kind of assay device that can accurately measure nozzle rotating angle, including jet pipe and installation standpipe, the shower nozzle collar it is cased with on described jet pipe, it is fixed with Long pointer on the described shower nozzle collar, it is cased with, on described installation standpipe, the set that is located by connecting, described be located by connecting to be enclosed within the one side of the corresponding described shower nozzle collar be fixed with angulometer, the arrow of described Long pointer is perpendicularly oriented to the scale on described angulometer surface.
In such scheme, between arrow and the scale of described angulometer of described Long pointer, keep the distance of 2-3mm.
In such scheme, described angulometer is annular, and the scale set-up mode on described angulometer: 2 degree is little lattice, and 10 degree is lattice in, 30 degree is big lattice.
In such scheme, described angulometer uses with the described set that is located by connecting threadeds.
In such scheme, the side of the described shower nozzle collar is provided with the described location hole b that is connected by of some location hole b, the described shower nozzle collar and described jet pipe and realizes with coordinating of screw.

Fig. 1 is apparatus of the present invention structural representation.
Fig. 2 be in Fig. 1 A-A to profile.
Fig. 3 is the nested structure schematic diagram that is located by connecting.
Fig. 4 is the schematic front view of angulometer.
Fig. 5 is that intention overlooked by angulometer.
In figure, be 1. located by connecting set, 2. angulometer, 3. Long pointer, 4. the shower nozzle collar, 5. jet pipe, 6. external screw thread, 7. location hole a, 8. internal diameter, 9. female thread, 10. location hole b, and 11. install standpipe.
Detailed description of the invention
As shown in Fig. 1 Fig. 5, the present invention includes the set 1 that is located by connecting, angulometer 2, Long pointer 3, the shower nozzle collar 4, jet pipe 5, external screw thread 6, positions hole a 7, internal diameter 8, female thread 9, location hole b 10 and installation standpipe 11, wherein, the set 1 that is located by connecting uses location hole a 7 to be connected with screw with installation standpipe 11, location hole a 7 is evenly distributed in set 1 side that is located by connecting, and is held in position adapter sleeve 1 and installs standpipe on same centrage；Being located by connecting set 1 internal diameter 8 slightly larger than installing standpipe external diameter, regulates screw, the set 1 that makes to be located by connecting is fixed on installation standpipe.The internal thread hole 9 of angulometer 2 is connected with the external screw thread 6 of the set 1 that is located by connecting, and internal thread hole 9 diameter of angulometer 2 overlaps external screw thread 6 equal diameters of 1 with being located by connecting；Angulometer 2 circular scale totally 360 degree, it is little lattice that the graduation mark on angulometer 2 is 2 degree, and 10 degree is lattice in, and 30 degree is big lattice, and graduation mark is 0.3-0.5mm deeply；The shower nozzle collar 4 is annular, and the shower nozzle collar 4 uses screw to be connected by location hole b 10 with jet head 5, and location hole b 10 is evenly distributed in the shower nozzle collar 4 side, and the shower nozzle collar 4 rotates together along with jet head 5；Long pointer 3 welds with the shower nozzle collar 4, and Long pointer 3 is perpendicular to angulometer 2, and Long pointer 3 low side and angulometer 2 keep the distance of 2-3mm, its object is to ensure accuracy of reading and without frictional resistance.
Work process is as follows: during measurement, as it is shown in figure 1, be connected by the external screw thread 6 of the female thread 9 of angulometer 2 with the set 1 that is located by connecting, and is enclosed within installation standpipe 11, uses location hole a
7 position with screw.Different installation standpipes 11 can use different set 1 internal diameters 8 that is located by connecting to be attached.The shower nozzle collar 4 use screw by location hole b
10 are connected with jet head 5.Shower nozzle is during rotating, and the collar 4 rotates together along with shower nozzle.Long pointer 3 rotates together along with shower nozzle.During record sprinkler rotation initial, the arrow indication angle of Long pointer 3, when shower nozzle turns over certain angle or stepping certain angle, can read angle shown in the angulometer 2 corresponding to the arrow of Long pointer 3, completes the measurement of shower nozzle step angle or the anglec of rotation.
