Description
Technical field
The present invention relates to a kind of hydrographic survey device, particularly a kind of ultrasonic water level automated watch-keeping facility that adopts ultrasound wave automatically to monitor river level.
Technical background
Hydrology department is observed hydraulic condition of river information throughout the year, and wherein, the waterlevel data in river course is important hydrographic information.Traditional Level monitor generally adopts gauge mode, and the position in river course near bank arranges gauge, and general relatively more steady, the little feature of wave of position current of utilizing river course to pull in to shore is directly carried out reading on gauge.This gauge metering system cost is low, but needs artificial reading, cannot provide continuous measurement data, and the in the situation that of bad weather, read-around ratio is more difficult.
Adopt in addition the measuring method of float-type, in river course, one side is offered vertical measuring well, and the bottom of measuring well is communicated with river course, forms linker, a float is set on the water surface of measuring well, obtains water level information by the float driving mechanical meter deflection of floating.Although this metering system is stable, construction cost is high, is not suitable for extensive multipoint application.Therefore most places level measuring still adopts the mode of gauge.
Utilize in addition at present ultrasonic transducer to measure water level, as the Chinese patent CN202599479U of bulletin on Dec 12nd, 2012, name is called a kind of river water level monitor, this device comprises firm banking, support and suspension rod, described support is arranged on firm banking, suspension rod is arranged on the top of support, mid-stent is also arranging circuit box, support top is provided with alarm lamp harmony alarm, one of suspension rod is provided with measuring cylinder, and described measuring cylinder inside is provided with ultrasonic transducer and temperature sensor.This device is chosen sky by ultrasonic transducer and is arranged on water surface top, utilize water-reflected to obtain waterlevel data, ultrasound wave is propagated in air, airborne temperature, humidity can produce larger impact to the precision of ultrasonic measurement, when especially humidity is higher, can form droplet at ultrasonic transducer probe, measuring accuracy is affected greatly, and due to the situation of change complexity of temperature humidity in air, measurement mechanism is larger apart from the water surface error producing far away, precision is lower.The west area such as in Xinjiang of China, river water level height change is little, according to waterlevel data over the years, high and the minimum fluctuation of water level is even in 5 meters, said apparatus can be arranged on 5 meters of left and right of the water surface and can ensure can not be submerged, and this ground weather is throughout the year comparatively dry, adopt said apparatus can obtain higher measuring accuracy.And in the southeast such as Zhejiang, Jiangsu, some river water level amplitude of variation even can reach more than 20 meters, it is very high that corresponding measurement mechanism must arrange, even reach 30 meters apart from the water surface, and air themperature humidity changes greatly, utilize water-reflected ultrasonic measurement waterlevel data can produce very large error.
Summary of the invention
The object of the invention is to solve ultrasonic water level measurement mechanism that the existing water surface chooses sky formula above and change large regional measuring error problem greatly at temperature, humidity, river water level, a kind of ultrasonic water level automated watch-keeping facility of underwater ultrasound level measuring is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ultrasonic water level automated watch-keeping facility, comprise the column being arranged on riverbank, the top of column is provided with chooses sky and sets up the crossbeam of river course top, on the riverbed of described crossbeam below, water the concrete foundation of the level of being provided with, between crossbeam and concrete foundation, be provided with at least two vertical guide lines, guide line is provided with and swims in water surface upper floating ball, ball float is hermetic water-proof structure, middle part, ball float bottom surface is provided with cavity, ultrasonic transducer is set in cavity, in ball float, be also provided with the accumulator that electric energy is provided, deal with data the telemetering terminal transmitting, ball float is also provided with the solar panels into charge in batteries towards a southern side.Ball float is subject to the restriction of guide line, floats on the surface and slides up and down with water level, and concrete foundation is not only as the fixing basis of guide line, and is the benchmark that level measuring converts, and between fixing concrete foundation and riverbed water level, has fixing conversion relation.The ultrasonic transducer of ball float bottom sends the reflection of signal through the concrete foundation on riverbed, or measurement data, then can accurately obtain waterlevel data after converting.Ultrasonic propagation medium is taking water body as medium, air dielectric relatively, water body medium character is stable, and the impact that ultrasonic propagation is caused is fixed substantially, with easily calibration, be more suitable for that air humidity, temperature variation are large, the river water level discrepancy in elevation changes area greatly.The data that ultrasonic transducer records, after the rough handling of telemetering terminal, are wirelessly transmitted in hydrometric station.Solar panels are charge in batteries in having sunlight, meet overall operation demand.
As preferably, described guide line is two that walk abreast, and ball float both sides are respectively equipped with two guide lines and are socketed the collar coordinating.
As preferably, the top of described ball float is provided with the antenna being connected with telemetering terminal.
As preferably, the position that described cross bar is corresponding with guide line is provided with back-moving spring, and the upper end of guide line is fixed in the bottom of column through behind the lower end of back-moving spring.Back-moving spring can provide long fastening effect, avoids guide line loosening.
As preferably, described ball float is bottom surface plane, and top is hemispherical semisphere, and ball float hemisphere face is provided with maintenance window with too can a plate relative side, and maintenance window periphery is provided with O-ring seal.
As preferably, the hemisphere face of described ball float adopts fiberglass to make.
Basis, ball float ultrasonic measurement riverbed to the altitude information between the water surface that utilization of the present invention swims in the water surface is converted into waterlevel data, utilize the water body of stable in properties as ultrasonic medium, the impact of having avoided air humidity, temperature variation to propagate ultrasonic signal, makes ultrasonic measurement workable moisture, temperature, the water level discrepancy in elevation change area greatly.
