Abstract
The utility model provides a skip type rain telegauge which is suitable for the rainfall observing and measuring of the hydrotechnics river channel in the high-water season. The utility model is composed of a skip rainfall section which can drive the swinging of magnetic steel to cause a magnetic induction switch to be operated, and a digital display section which can be arranged indoors to be observed. The utility model has the advantages of convenient installation and operation, simple structure, low cost, and less power consumption. Compared with the skip type rainfall gauge for weather, the utility model uses the digital display to replace a mechanical count and a recording instrument, while five batteries in size five are enough to be used for one year, and the circuits can store the rainfall data for one year.
Description
The utility model relates to a kind of instrument of improved mensuration rainfall amount, is specially adapted to the tipping bucket type telemetering rain ga(u)ge of water conservancy river course rainfall in flood season observation usefulness.
Measuring the amount of rainfall flood season in the water conservancy river course and generally adopting diameter is the udometer of 20 centimetres round metal tubular, and it is necessary.Observation station braves the rain to measure, and uses not only inaccurate but also inconvenient.Meteorologic analysis rainfall amount specialized equipment tipping-bucket rain-gauge adopts mechanical count, the cost height, and volume is big, is not suitable for general flood control unit and uses.
Task of the present utility model provides a kind of suitable night-time observation, tipping bucket type telemetering rain ga(u)ge easy to install.
Task of the present utility model is that following mode is finished, and it forms the tipping bucket rainfall part and the electronic digit display part of magnetic induction switch action by driving the magnet steel swing, and digital display portion can be placed on indoor observation, and is easy to install.Compare with tilting bucket rain with meteorology, show with numeral to replace mechanical count and registering instrument, cost is low, and suitable basic unit observation station is used.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1.Oblique view for an embodiment of the present utility model.
Fig. 2.Electric functional-block diagram for an embodiment of the present utility model.
Fig. 3.Electrical schematic diagram for an embodiment of the present utility model.
As shown in Figure 1, this rain gage is made up of tipping bucket udometer part 1 and electronic digit display part 2.Tipping bucket udometer part 1 is installed in test point, and electronic digit display part 2 is installed in indoor.
The electricity principle is seen Fig. 2. Fig. 3. shown in, be connected to pulse signal of on-off circuit 10 generations of electronic digit display part 2 from the magnetic induction switch J of tipping bucket rainfall part 1, enter monostable circuit 20 then, enter bistable circuit 30 again, bistable circuit 30 outputs divide three the tunnel, one the road to decimal counting circuit 70, it outputs to the sound equipment part 80 of raining, whenever the rainwater that falls some produces a sound equipment, another road makes the binary bit counting show 0.5 to decimal circuit 40, and Third Road is counted/deposited/latch/decipher/driving circuit 51 to three successively, 52,53, show by display board 60, manually and automatically show by time-delay display circuit 90 control display boards 60.
During work, first power turn-on K switch
1Push switch K
4K
6Make decimal put " 0 ", each counting circuit 70,51,52,53 is put " 0 ", when the external world has rainfall to make the tipping bucket upset, owing to drive the magnet steel swing, makes magnetic induction switch J action, makes the BG that is in cut-off state at ordinary times
1Conducting rapidly is in resistance R
1Last generation one high level triggers the monostable circuit of being made up of d type flip flop 20, makes it be in temporarily steady state, Q
1Be low level, Q
1Be high level, reply ortho states through monostable circuit behind the certain hour 20, it keeps receiving only a pulse signal within a certain period of time, avoids magnetic induction switch J at the instantaneous repeatedly closed disturbing pulse that produces.Press K
6Key makes all numeration circuit zero clearings, and presses K
4Key makes the Q of bistable circuit 30 binary bits 1 of d type flip flop composition
2Be high level, Q
2Be low level, it is for showing that rainfall amount is provided with.Every bucket rain is 0.511 rainfall amount.When monostable circuit 20 recovers ortho states Q
1During for high level, bistable circuit 30 upset Q
2Be low level, Q
2Be high level, at this moment BG
2Base stage obtains noble potential, makes the decimal place of display circuit 60 show " " and " 5 "; Simultaneously by diode D
1Trigger high level for the CP end one of decimal counting circuit 70, make r
1End is high level, triggers music integrated circuit 80 playing musics by C.After the magnetic induction switch closure second time, the Q of bistable circuit 30
2Be high level, Q
2Be low level, triode BG
2End, decimal does not show, Q
2The high level rising edge trigger ten to advance to count/deposit/latch/decipher/driving circuit 51,52,53 is respectively ten and hundred figure places, K
2Be the digital latch switch.D
2-D
6Be buck diode, for music integrated circuit 80 provides 3V operating voltage, as rainfall and when counting, that will accuse is rainy like this, and tipping bucket upset 20 times, just plays once when promptly rainfall amount is 10mm.
Its adopts 7.5V power supply, and five joint No.5 cells get final product, is prolongation battery service time, by triode BG
3Formed timing relay power amplifier 90, delay time ten seconds is convenient to observation, works as BG
3Base stage when being noble potential, BG
3Conducting, relay J
1Adhesive, its normally opened contact J
1Make digital the demonstration, by K switch
5And K
3Control is digital manually to be shown or shows automatically.It is one group that this number display board adopts three luminotrons, as one section that counts, seven groups of bits per inch words, decimal is used six groups, only shows radix point and " 5 ", and this circuit adopts the CMOS integrated circuit, can make working current minimum, five joint No.5 cells can use about 1 year, and the maximum count of this circuit is 999, can deposit the rainfall data in 1 year.
Claims (2)
