Intelligent multi-cabin suspended sediment sand content sampling system

Abstract

The invention discloses an intelligent multi-cabin suspended sediment sand content sampling system which comprises a multi-cabin collector, a fish lead and a control unit, wherein the multi-cabin collector comprises an installation frame and a plurality of samplers arranged on the installation frame, the control unit comprises a control cabin fixedly arranged on the installation frame, the controlcabin is a cylinder, the two ends of the cylinder are sealed, a power supply and a programmable logic controller are arranged in the control cabin, a temperature sensor and a water depth sensor whichare respectively and electrically connected with the programmable logic controller are arranged at one end of the control cabin, the plurality of the samplers are respectively and electrically connected with the programmable logic controller, the programmable logic controller can control the samplers to be turned on and off, a vertical connection rod is fixedly arranged at the top end of the fishlead, a horizontal shaft is fixedly arranged at the top end of the connection rod, the horizontal shaft is arranged in a vertical sliding groove at the bottom of the installation frame in a sliding mode, and a bottom touch sensor electrically connected with the programmable logic controller is fixedly arranged at the top of the vertical sliding groove. The intelligent multi-cabin suspended sediment sand content sampling system disclosed by the invention greatly improves sampling efficiency and ensures safety of workers.

Description

technical field [0001] The invention relates to the technical field of sampling suspended sediment content, in particular to an intelligent multi-bin suspended sediment content sampling system. Background technique [0002] Suspended sediment refers to the finer sediment and colloidal substances suspended in the flowing water of the river and moving downward with the flowing water. The determination of the amount of sediment is particularly important, and the determination of the suspended sediment content first requires sampling. At present, the sampling of suspended matter is carried out directly in the river water by the staff on the survey ship holding a single-compartment manual sampler. It is inconvenient to use, the labor intensity of the staff is high, and the sampling efficiency is low. Unnecessary potential safety hazards, and the sampling of suspended matter at different water depths at a single specific location cannot be realized, and the specific water depth o...
