Controller is thought to have been carried out, not within the utility model.It should be noted that moisturizing change water installations can be at regular time and quantity
Moisturizing, overflow mechanism being capable of accurate measurement spillway discharges.
1, measuring device:
It is 200mm side bucket 7 that a diameter, which is arranged, in 2 side of E601B evaporator, and a connecting pipe 3 and evaporation is arranged in lower part
Device 2 is connected to, and side bucket 7 is fixed on the base.2 lower part of evaporator should be set communicating pipe 3, communicating pipe 3 use 6 distributive pipes,
Pipe range is appropriate, and the viscosity of water is avoided to impact test precision.Solenoid valve 4 is set on communicating pipe 3, in side bucket 7
Outlet pipe 8 is arranged in appropriate height and position, and outlet pipe 8 installs solenoid valve 9；Setting weighing bucket 12, outlet pipe 8 at outlet pipe 8
Water be discharged into weighing bucket 12 and do not contacted with weighing bucket 12, weighing 12 lower part of bucket installation drainpipe 13 and solenoid valve
14, for exhausting the water in weighing bucket 12, weighing bucket 12 is placed on weighing apparatus 11.When needing to monitor, connection is closed
Solenoid valve 4 on pipe 3 opens the solenoid valve 9 on outlet pipe 8, and the water of 8 or more outlet pipe enters weighing bucket in side bucket 7
12, water is obtained by weighing apparatus 11,2 water level of evaporator can be calculated by the weight of water, when the water-head monitored twice is
Section evaporation capacity.Protection cylinder 5 and protection cylinder 10 are respectively set outside side bucket 7, weighing bucket 12 and weighing apparatus 11, protects cylinder
Heat insulation layer is set on 10 barrel, avoids side from setting moisture in bucket and evaporates, while rainfall being avoided to influence.
2, working system:
According to evaporation from water surface observation criteria, when evaporation from water surface mainly monitoring daily evaporation amount, the i.e. same day 8 to second day 8
Evaporation capacity, therefore, under normal conditions daily 8 when monitoring can once meet needs.Set evaporator overflow hole bottom or less
Evaporator water level is zero at 230mm, then overflow hole bottom water position is 230mm, it is that water is set at 150 mm in evaporator water level
Bit flag line.It is at 50mm that water level, which is preferably arranged in, in side bucket water outlet.In first operation, when the same day 8 before, infused to evaporator
At water to 150 mm of water level, communicating pipe solenoid valve is closed, measures evaporator accurate water level with stylus, input controller was as the same day
Originate water level.Then side bucket outlet valve is opened, so that the water for being higher than water outlet or more is discharged into weighing bucket, then weighs and count
Calculate water level.The water level and calculating water level adjustment side bucket water outlet bottom water place value measured according to stylus, input controller.
Hereafter daily 8 when, open communicating pipe solenoid valve, so that evaporator and side bucket water level is reached stable and consistent, then
Closing communicating pipe solenoid valve, opening are other to set bucket outlet valve, so that the water for being higher than water outlet or more is discharged into weighing bucket, then weighs
And calculate water level；Weighing bucket drain valve is opened, the water of weighing bucket is completely exhausted out, closes solenoid valve.
Information collection is automatically performed by device.Evaporator moisturizing and overflow metering are automatically performed by system, and the part is
There is ready-made device, is repeated no more.When evaporator 8, water level is less than or equal to 90mm, water replanishing device quantitative water compensating 18kg makes
Evaporator water level reaches about 150mm, then primary according to above method monitoring water level, originates water level as the same day.Due to this
In monitoring process, the water in evaporator often updates device, can guarantee that water body does not become morally degenerate, thus the present apparatus without
Water need to be changed.
3, evaporator water level and daily evaporation amount calculation method:
If originating water level when the evaporator same day 8 is H1(mm), the weight of weighing bucket water is W1, latter day 8:00 water level is
H2, the weight of weighing bucket water is W2, side bucket overflow hole bottom water bit constant is H0(mm)；Daily evaporation amount is E, intra day ward
For P, it is WY that spillway discharge, which is converted into the evaporator depth of water, and E, P and WY unit are millimeter, and unit of weight is gram to retain a decimal.
If side bucket internal diameter cross-sectional area is f (cm2), evaporator internal diameter cross-sectional area is F (cm2)。
(1) initial water level calculates:
Water level is originated when the first day (starting first day monitored automatically) 8 are as follows:
H1=H0+10W1/f
Monitoring or calculated value when non-first day initial value is upper one day 8, it may be assumed that
W1= W2
H1=H2
(2) same day is there is no when precipitation, water level and evaporation capacity calculation formula are as follows:
H2=H0+10W2(1/f+1/F)
That is, E=H1-H2=10[W1/f-W2(1/f+1/F))]
(3) there is precipitation but when without overflow
E=H1-H2=10[W1/f-W2(1/f+1/F))]+P
(4) when there is overflow in the same day
E=H1-H2=10[W1/f-W2(1/f+1/F))]+P-WY.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
