Abstract

The invention discloses a benthal deposit collecting system and method. The benthal deposit collecting system comprises a platform extending out of a ship, a vertical column arranged on the platform,a vertical cylinder with the open lower end, a plurality of ultrasonic ranging sensors arranged on the peripheral face of the vertical cylinder, and a plurality of drainage cylinders arranged on the vertical cylinder and arrayed in the circumferential direction of the peripheral face of the vertical cylinder, wherein the vertical cylinder is rotationally connected with the vertical column; the benthal deposit collecting system further comprises a supporting column arranged on the ship, an L-shaped corbel arranged on the supporting column, and a pallet arranged on the corbel; and a corbel motorused for driving the L-shaped corbel to rotate is arranged in the supporting column, and the corbel motor is electrically connected with a controller. The benthal deposit collecting system has the characteristics that automatic lifting can be achieved, a deposit layer can be taken out from benthos completely, operation is convenient, and the influence on the benthal environment is small.

Description

technical field [0001] The invention relates to the technical field of sampling tools, in particular to an underwater sediment collection system and method with simple operation, high reliability and high sampling efficiency. Background technique [0002] The various sources of sediment deposited on the bottom of the water include suspended matter such as sediment entrained in rivers, rivers, lakes, and sea water; the remains of aquatic organisms and their decomposition products; water pollutants, especially mercury, cadmium, lead, zinc, Heavy metals such as nickel and organic substances with strong adsorption. Through the analysis of the physical, chemical, and biological characteristics of the bottom sediments, as well as the study of the depositional environment, it is possible to find out the types of pollutants in the past, determine the degree of pollution, and determine the location of the pollution source. [0003] At present, the sediment collection device is mainl...
