The invention discloses a Yangtze
estuary bottom sand transport rate measuring
system and
observation method, and the
system comprises a sand collection
barrel which is used for being buried in an
observation point to collect bottom sand; a weight
measuring instrument, used for acquiring the weight of the bottom sand in the sand collecting
barrel; a
dynamic balance module, used for keeping the sand collecting
barrel in a set state; a pressure meter, used for acquiring
water pressure in the sand collecting barrel; a waterproof acquisition module, used for acquiring data of the weight
measuring instrument, the
dynamic balance module and the pressure instrument; a
wireless transmission module, used for sending the measurement data to an upper computer; a power supply module providing
electric energy for components; and a high-pressure waterproof box, used for protecting all electric components from being damaged and wetted by
water pressure. The sand collecting barrel and the sand quilt skirt are combined, and the weight
measuring instrument, the
dynamic balance module, the
data acquisition instrument, the
wireless transmission module and the power supply module are combined, so that the problems that a traditional
sediment transport amount measuring
system is poor in measuring precision, is greatly influenced by terrains and cannot observe the
sediment transport amount in real time are solved, and the system is better applied to relevant scientific research projects of hydrological survey.
