The invention has the advantages that:
1, because the present invention uses the electromagnetic valve switch on the different sampling bottles to distribute rainwater in each sampling bottle, do not have rotary distribution apparatus, do not require high-accuracy mechanical and electronic installation, reliability is higher;
2, be fit to open-air and do not have the occasion of AC power.Solenoid valve adopts direct current 24V, but adopts storage battery power supply continuous working 240 hours.Also can finish the automatic control of teletransmission data, the operate as normal when guarantee operating personnel's safety or unmanned;
3, connect rain drain bucket and submersible pump pumping two cover rainwater collector units because the present invention has adopted, both can collect natural rainfall, also can collect rainfall runoff, be fit to the collection of rainwater under the various situations, the applicability of device is stronger.
