Description of drawings
Fig. 1 is the fundamental diagram of the embodiment of the described a kind of full-automatic evaporate station of the utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment
A kind of full-automatic evaporate station; As shown in Figure 1; Comprise rain gage 15, evaporating dish 6 and evaporation level measuring and control device, be connected with water replanishing device and overflow mechanism on the evaporating dish 6, evaporation level measuring and control device are connected with rain gage 15, water replanishing device and overflow mechanism respectively.
Water replanishing device comprises water butt 1, small pump 2 and filling pipe 3, and small pump 2 is installed on the water butt 1, and filling pipe 3 one ends connect small pump 2, and the other end connects evaporating dish 6.
Overflow mechanism comprises flood pump 4 and run-down pipe 5, and flood pump 4 is installed on the evaporating dish 6, and run-down pipe 5 one ends connect flood pump 4, and the other end is connected with hydrosphere 8.
Evaporation level measuring and control device comprise hand valve 9, communicating pipe 10, hydrostatic bucket 11, kickboard 12, laser range sensor 13 and data acquisition controller 14; Kickboard 12 is installed in hydrostatic bucket 11 tops; Laser range sensor 13 is installed in kickboard 12 tops with data acquisition controller 14, communicating pipes 10 1 end connection hydrostatic bucket 11, and the other end penetrates into evaporating dish 6 inside; An end that penetrates evaporating dish 6 communicating pipe 10 is provided with clipper tube 7, and hand valve 9 was installed on communicating pipe 10.
During work; The water yield, the flooding process of flood pump 4 and the moisturizing process of small pump 2 in 13 pairs of evaporating dishes of laser range sensor 6 are observed; Be sent to data acquisition controller 14 to the data that observe then; Data acquisition controller 14 is gathered automatically, is handled, and shows the information of evaporation, precipitation, flooding process then, controls the course of work of laser range sensor 13, flood pump 4, small pump 2 more automatically.Data acquisition controller 14 is connected with language profit telemetry terminating machine through the RS232 communication interface, utilizes language profit telemetry terminating machine can realize the remote monitoring and the data reorganization warehouse-in of evaporation from water surface procedural information.
Below to use the E601B evaporating dish to specify the course of work of the full-automatic evaporate station of the utility model as example.Evaporating dish 6 is that area is 3000cm 2The E601B evaporating dish, be that the hydrostatic bucket 11 of 250mm is communicated with measurement with diameter, so the value that measures through laser range sensor 13 need multiply by reduction coefficient y, y=(3000+12.5 when carrying out data operation 2* π)/3000=1.16.
Operating evaporate station evaporating dish 6 heights of water level should remain on the water-line target line.No precipitation is during day, and data acquisition controller 14 is gathered water surface elevation change calculations evaporation capacity in the evaporating dish 6 automatically.When water surface elevation is reduced to the following 10mm of water-line target line of " evaporation from water surface observation standard " regulation in evaporating dish 6; 2 work of data acquisition controller 14 control small pumps; Give evaporating dish 6, hydrosphere 8 automatic water supplements, make evaporating dish 6 middle water levels return to water-line target line height.The stable back of water surface data acquisition controller 14 is gathered the waterlevel data that laser range sensor 13 is measured, and the water-head reduction coefficient with 1.16 on duty before and after small pump 2 work is exactly a rate of water make-up so.
In precipitation day; More than evaporating dish 6 water levels are increased to the water-line target line of " evaporation from water surface observation standard " regulation during 10 mm; 4 work of data acquisition controller 14 control flood pumps; Flooding process finishes when making evaporating dish 6 middle water levels return to water-line target line height, and the stable back of water surface data acquisition controller 14 is gathered the waterlevel data that laser range sensor 13 is measured, and the water-head reduction coefficient with 1.16 on duty before and after flood pump 4 work is exactly the overflow value so.
According to " evaporation from water surface observation standard " and National Meteorological Bureau's " surface weather observation standard " regulation, the computing formula of evaporation capacity is:
Evaporation capacity=(evaporating dish water level value of starting at-evaporating dish level measuring value) * reduction coefficient+quantity of precipitation-spillway discharge+rate of water make-up;
