The utility model is implemented by following technical solution：Rainwash frequency conversion sampler comprising main body, the main body
It is interior to be equipped with sampling dish, several sampling bottles are placed in the sampling dish, the sampling dish drives by sampling electric rotating machine；Institute
It states and is connected with probe tube in main body, the outlet end of the probe tube is placed in across the main body above the sampling bottle, described to take
The input end of sample pipe is connect by sampling pump with suction hose；It includes float switch, transmissometer, frequency converter and controller, institute
It states float switch to be electrically connected with the sampling pump, the transmissometer and the sampling electric rotating machine respectively, the transmissometer and institute
Controller signals connection is stated, the controller is connect with the frequency converter signal, the frequency converter and the sampling electric rotating machine
Signal connects.
Further, the float switch includes mounting rod, and snap switch, the installation are fixed on the mounting rod
Sliding sleeve is connected to floating ball on bar, is equipped with annular magnet in the floating ball, the annular magnet is socketed in outside the mounting rod.
Further, a limit card block is separately installed on the mounting rod above and below the floating ball.
The advantages of the utility model：1, float switch monitors rainwash water, when earth's surface runoff water amount reaches predetermined value
When, float switch triggers sampling pump and transmissometer work, and sampling pump is sampled work, avoids the empty appearance for adopting problem, can carry
The efficiency of high sampling work；2, transmissometer is monitored the turbidity of rainwash, and is controlled by controller according to turbidity value
Frequency converter realizes the frequency conversion rotation of sampling electric rotating machine, further realizes the purpose of frequency conversion sampling, make sampling frequency can be according to reality
Rainwash border situation is changed, and improves the validity and accuracy of sampling work.
