Abstract
The invention discloses a full-automatic metering instrument for accurately measuring the water surface evaporation amount by using a national standard specification E610B evaporation pond mainly matched with applications in the fields of meteorology and hydrology. The invention provides a water-medium ultrasonic water surface evaporation metering device which is high in precision and resolution and does not destroy a spontaneous evaporation environment field; and a water-media ultrasonic transducer and a temperature sensor are immersed in a water body, at relatively stable temperature, in the E601B evaporation pond and are not irradiated by sunlight directly to result in compensation temperature deviation, so that the measurement precision is guaranteed effectively. On the basis of accurate measurement, a water-media ultrasonic processor is used for simultaneously controlling a water make-up and discharge system to make up water and discharge water automatically according to the elevation of a water level in the evaporation pond, and the full-automatic unmanned guard is realized effectively.
Description
Affiliated technical field
The present invention relates to a kind ofly mainly use, cooperate national standard standard E610B evaporation tank to carry out the fully automatic culculating instrument that water surface evaporation accurately measures by meteorological, hydrology field.
Figure viewed from behind technology
At present, along with the variation of climatic environment, country has strengthened the monitoring of atmosphere water yield round-robin, and the earth water surface evaporation is one of its important indicator.Water surface accumulative total vaporization loss in a certain under field conditions (factors) period is mainly observed in evaporation from water surface, rejects precipitation or other recruitment simultaneously, on surface level, shows as the reduction value of height of water level.Current evaporation from water surface measuring method; Be as the simulating nature evaporitic environment with the E610B evaporation tank; In the interval time of regulation, carrying out water level (accuracy requirement 0.1mm) and reduce DATA REASONING, generally is that manual pick is measured observation with vernier height gauge as survey instrument.Also there is the gas medium ultrasonic method of a small amount of employing to measure; Because gas medium ultrasonic sensor and corresponding protection annex equal-volume are big; Must hang on E610B evaporation tank water surface top again and use, directly influence sunshine to the irradiation of disengaging surface, also influence the evaporating field environment that air circulates naturally; Simultaneously, ultrasonic sensor receives sun direct projection and influence of temperature change, and accuracy error is very big; In addition, the gas medium ultrasonic sensor is from external import, because the factor of exchange of technology aspect can't realize robotization benefit, drain function on the automatic measurement basis.So this field never has the suitable instrument that accurately measures and realizes its automatic observation.
Summary of the invention
In order to improve the stability of measuring accuracy and continuous data; Overcome the end that covers of using instrument in the above-mentioned application, the present invention provides a kind of high precision, high resolving power and does not change the evaporator area of standard and the aqueous medium ultrasound wave evaporation from water surface WT-MSR of structural form.Aqueous medium ultrasonic transducer and temperature sensor are immersed in the metastable E601B evaporation tank of the temperature water body, can not receive solar radiation influence and cause the compensation temperature deviation, have effectively guaranteed measuring accuracy; The not enough 1.5cm of the thin walled tube sectional area of the 30mm that is fixedly connected with temperature sensor with the aqueous medium ultrasonic transducer
2Can not destroy standard evaporitic environment field, simultaneously, the thin walled tube of Φ 30mm plays the hydrostatic pipe, guarantees to measure water body and not influenced by stormy waves, and its structure and installation and maintenance are all very simple.
On the accurate based measurement of aqueous medium processor for ultrasonic wave, can mend draining automatically according to the water level elevation of evaporator sump by benefit, the unwatering system of its control, effectively realize the robotization unmanned.
The invention has the beneficial effects as follows, improve the precision of evaporation from water surface, grasp atmosphere water yield circulation law, realize the unmanned automatic monitoring.

Fig. 2 is the practical application picture of aqueous medium ultrasonic meter in the E601B evaporation tank
Specific embodiments
The upper edge of E601B evaporation tank (4) is fixing with hydrostatic pipe (2) through hydrostatic pipe hanger frame (1); The aqueous medium ultrasonic transducer (3) of hydrostatic pipe (2) bottom and the inner temperature sensor that embeds; Be immersed in the water body (9) of the metastable E601B evaporation tank of temperature (4), the water level in the hydrostatic pipe (2) is through water body (9) balance in liquid level through hole (11) and the E601B evaporation tank (4).
When ultrasonic measurement processor (7) and aqueous medium ultrasonic transducer (3); After the current water level (11) of E601B evaporation tank (4) measured; The waterlevel data that ultrasonic measurement processor (7) will last time be measured and store compares calculating, data is stored and is exported after drawing evaporation number.Subsequently; Ultrasonic measurement processor (7) is decision making according to current water level (10), and when being lower than the setting value of code requirement as if water level (10), ultrasonic measurement processor (7) and aqueous medium ultrasonic transducer (3) will continue surveying work; Simultaneously; Startup and control water charging system (8) carry out moisturizing to E601B evaporation tank (4) and evaporation tank adapted hydrosphere (5), and when mending setting value, water charging system is closed in ultrasonic measurement processor (7) control.Thus, aqueous medium ultrasonic measurement processor (7) realizes accurately measuring and realizing that unmanned is full-automatic under the situation that does not change evaporator regulation water area and structural form.
