Bottom mud suspending and sampling device for simulating ship disturbance

Abstract

The invention discloses a bottom mud suspending and sampling device for simulating ship disturbance and belongs to the technical field of water quality detection. The bottom mud suspending and sampling device comprises a supporting device, a connecting part connected with the supporting device, a driving part which is mounted at the bottom of the connecting part and is provided with an output end at the bottom, a propeller mounted at the output end at the bottom of the driving part, and a sampling part; through holes are formed in the middle of the propeller and the middle of the driving part, and the propeller and the driving part are communicated with each other; and the sampling part sequentially penetrates through the propeller and the driving part to be connected with the connecting part. According to the bottom mud suspending and sampling device for simulating ship disturbance, the situation that a ship is located at different river environments and sails at different allocated speeds is simulated, so that the effect of the suspending of bottom mud by the propeller can be observed, so that the condition of the pollution of the bottom mud can be embodied indirectly;data analysis and exploration are carried out from the radial and depth distances of the ship propeller, so that more possibilities are added for experimental results, and experimental data are more comprehensive.

Description

technical field [0001] The invention relates to a bottom mud lifting and sampling device for simulating ship disturbance, and belongs to the technical field of water quality detection. Background technique [0002] Under the impact of water flow, the sediment deposited at the bottom of the river will be eroded and suspended, and will be released from the endogenous source. The released trace elements, pollutants and other substances will cause changes in water quality. Endogenous release has a great impact on the water environment, which may lead to changes in microorganisms and the number of aquatic organisms. Therefore, it is necessary to study the sediment suspension technology, how to analyze the microscopic mechanism of sediment suspension, and study the influence of ship propeller disturbance on There is a lack of actual research on the effect of sediment suspension at this stage, and the combination of sediment suspension and propeller disturbance has certain theoreti...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a kind of bottom mud suspension and sampling device for simulating ship disturbance, by simulating the situation that the ship is located in different river environments and sailing at different paces, observe the impact of the propeller on the bottom mud The suspension effect indirectly reflects the pollution of the sediment. At the same time, data analysis and exploration is carried out from the radial and depth distances of the propeller of the ship, adding more possibilities to the experimental results and making the experimental data more comprehensive.
