Underwater sludge sampling device with diving function

Abstract

The invention discloses an underwater sludge sampling device with a diving function. The device comprises a device main body, a diving device motor, a filtering device, a sludge sampling pipe and a propeller, wherein a central storage column is mounted in the center of the interior of the device main body; a battery bin is formed in the lower part of the central storage column; a diving device motor bin is arranged above the battery bin; the diving device motor is placed in the diving device motor bin; a wire coil connecting rod is connected to the upper part of the diving device motor; and the upper part of the wire coil connecting rod is connected with an iron cable wire coil. According to the invention, the sludge sampling pipe is mounted below the diving device; the sludge sampling pipe can be inserted into sludge through pressure generated when the device main body sinks, so that a sampling pipe baffle rotates upwards to enable the sludge to enter the sampling pipe, and the sampling pipe baffle cannot rotate downwards due to the fact that the area of the baffle is larger than that of the sampling pipe when the sampling pipe ascends after sampling is completed, so that the sludge is prevented from leaking out.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an underwater mud sampling device with a diving function. Background technique [0002] Silt is unconsolidated soft fine-grained or very fine-grained soil deposited in still water or slow flowing water environment, formed by physical, chemical and biochemical actions, and the silt of polluted lakes also contains quantitative pollutants, which can pass through The pollutants in the silt in the lake are used to analyze the cause of the lake's pollution. [0003] The existing sampling method for underwater silt is mainly to take a boat to the center of the lake to salvage and sample the silt with traditional tools, but the salvage efficiency is low, and the silt layer after salvage is chaotic, and the formation time of each layer of silt cannot be determined. for analysis. Contents of the invention [0004] The object of the present invention is to provide a kind o...
