Background technology
Silt-determination measure is the important component part of hydrologic survey work, and the silt data is the important evidence of flood control and disaster reduction, fwaater resources protection and engineering design.From the 1950's, the hydrologist just crosses many silt-determination measure instruments with domestic relevant R&D institution cooperation research and development.After the reform and opening-up, also attempt from some silt-determination measure instruments of external introduction.But the silt-determination measure instrument to the Yellow River never is well solved.The silt-determination measure of the Yellow River hydrology system overwhelming majority is at present still being used instantaneous formula sampling thief sampling, handles through methods such as displacements and calculates silt content.This method not only labour intensity is big, and measuring error is big, and is controlled poor, the data processing trouble.And change procedure that can not continuous monitoring natural river course silt content.For this reason, Hydrological Bureau of yellow committee project verification development silt on-line monitoring instrument.Online silt-determination measure instrument, can promptly monitor with the continuous acquisition natural river course in the silt content data, and the silt content data transmission that will survey to the Yellow River the flood control command center, solve the ageing of silt-determination measure effectively.Silt on-line monitoring instrument need carry out staking-out work before using, and the main contents of its staking-out work are exactly to set up the relation that receives factors vary such as temperature according to situation such as the water quality of survey station section current, silt contents, so that instrument normally drops into application at survey station.Degree of stability to water temperature in the demarcation is had relatively high expectations, and does not have suitable caliberating device at present, need research and develop.
Summary of the invention
The utility model is invented a kind of hydrologic and silt marking apparatus; This hydrologic and silt marking apparatus can stir the silt in the container according to the requirement that " silt on-line monitoring instrument " demarcated; Test request is satisfied in water temperature variation in the test process; Bubble does not affect greatly test result in the water body, and water velocity and water sample concentration (silt content) satisfy testing requirements, and the apparatus structure design can make things convenient for sampling operation.Current flow in a looping fashion in the marking apparatus, so claim " circulating hydrologic and silt marking apparatus ".The present invention is an online silt-determination measure instrument development " booster rocket ", is the important step that online silt-determination measure instrument development successfully reaches effective application.
The technical matters that the utility model will solve:
1. disturb husky concentration: instrument satisfies the silt content index of demarcating; 2. sediment size: satisfy the thickness degree of demarcating silt; 3. test the size of water body: the acquisition capacity of satisfied demarcation silt and stated accuracy, representativeness; 4. in the calibration process, the situation of change of water temperature satisfies instrument requirement; 5. satisfy test event, method of testing, power of test requirement in the calibration process; 6. in the calibration process, should not influence the effect of instrumental calibration to the disturbance of water body.
Technical scheme
The utility model solves the technical scheme that its technical matters adopted: instrument primary structure test water tank, preceding mozzle, back mozzle, middle mozzle connect for the horizontal annular structure, form tank.Tank divides tubular and water tank shape two parts.Barrel portion designs for enclosed construction, mainly carries out current and quickens and stir silt; Water tank partly designs for hatch frame, and test water tank sidewall is made with clear glass, mainly makes things convenient for the installation test instrument and is convenient to test operation.Tank limit wall is designed to streamlined or the smooth transition type.But level of barrel portion indoor design promotes the screw propeller of current, and horizontal propeller is a side entering type, and mozzle was inner before rotation axis one end stretched into, and an end is at preceding mozzle lateral wall.Screw propeller power is provided by exterior motor.The rotation thrust of screw propeller promotes current and flows along annular water tank, and the silt that adds in the water tank is stirred.For obtaining different water velocities, motor adopts Frequency Converter Control speed.
The beneficial effect of the utility model is: 1. inner water body flows complete in the streamline structural design, has guaranteed to stir the phenomenon that husky process can not have sedimentation; 2. the horizontal propeller side entering type advances water movement, makes the silt in the water body be in the turbulent fluctuation state constantly, forms evenly higher carrying water body; 3. the VFC motor speed is adopted in power design, to adapt to the power demand of different carrying water bodys, stirs husky range and reaches more than the 800Kg/m3; 4. adopt the heavy design of cooling down of pressing, bubble is to the influence of measuring accuracy and accuracy when having prevented to stir silt.5. the instrument test case is transparent, and current water observation is clear, and volume is little, conveniently moving.
