Critical piece function
Standard sample container is for holding the river to be measured after filtering silt, and sample container is for holding the river to be measured containing silt
And its dischargeable capacity is identical with standard sample container.Standard sample container and sample container such as can use at the bore hydrostatic column, arrange
Mutually level overfall position ensure that two containers have identical effective volume, extracts effective body of river to be measured i.e. every time
The river volume removing silt that is long-pending and that hold in standard sample container is equal, now weighs sample container with weighing instrument,
I.e. can get of poor quality.
Weighing instrument instructs quality (actually sample container and the mark under equal-volume to sample container according to what master controller sent
Quasi-sample container of poor quality) carry out weighing weighing result is returned to master controller simultaneously, water pump is according to the instruction of master controller
By in river suction sample container to be measured.
Master controller acts accordingly, simultaneously by weighing instrument for controlling water pump, weighing instrument and electromagnetic valve according to testing requirement
The data passed back are sent to neighbouring wireless data receiver by antenna, the number that master controller is sent by wireless data receiver
According to passing to PC host computer after signal processing, PC host computer includes the software program matched with wireless data receiver, uses
In typing field calibration data, measurement data is shown, record.
Operation principle and process
The present invention draws the sediment charge containing Shahe water to be measured indirectly by measurement is of poor quality, owing to using bascule structure,
The most first lever system adjustment and base horizontal adjustment the most first to be filtered to be measured containing Shahe water
Paper loads in standard sample container after filtering so that it is just till overfall overflows；Water pump is exported frequency variation signal by master controller
Drive pump motor to work, use pressure switch to realize closed loop control, constant pressure water supply simultaneously；Weighing instrument uses with high accuracy
The electronic balance (if maximum capacity quality is 300g, resolution is 0.01g) that resistance strain type sensor is measured as front end；
Master controller can use one chip microcomputer (abbreviation single-chip microcomputer), first brushes into program in single-chip microcomputer before using, and device makes
With front by the condition needed for the key-press input work on master controller；Master controller and water pump, electronic balance, electromagnetic valve
Being connected, it is to be measured containing Sha Heshui that master controller controls water pump extraction according to the working condition of input, makes in sample container muddy water from overflowing
Till head piece flows out, now sent instruction by master controller and allow electronic balance carry out weighing and return data, finally by wireless
Data sink upload to after having processed data PC host computer carry out showing, record.All working complete after by master controller
Sending instruction allows the electromagnetic valve of discharge outlet in sample container open, and treats that next time measures use closing valve after muddy water emptying.Lead
Water pipe and sample container overfall horizontal plane keep certain distance to be to prevent the vibration of aqueduct or moving influence from containing sample appearance
The gross mass of device.
If container volume is V, weighing instrument measurement to quality be m, standard sample container is equal with sample container effective volume,
The sand quality contained in muddy water in sample container is m1, in standard sample container with sand in sample container occupied by same volume
Liquid quality be m2, then have: m=m1-m2。
If density husky in muddy water is ρ1, the river density removing silt is ρ2, have
If θ is sand content in river water to be measured (mass content), can obtain
Comprehensive above equation can obtain after arranging:
ρ in above formula1And ρ2Being basically unchanged in identical location, can measure at the scene and once demarcate, typing is upper subsequently
Machine software and front-end detection device carry out measure batch.
