Embodiment

[0033] Step 1: Tie the cable to the lifting ring 1-3 on the sampling ship, one end of the cable is connected to the vibrator 1 through the watertight joint 1-2, the signal line at the other end is connected to the host computer 5 through the USB interface, and the power supply line is connected to the generator. Power the instrument on board and turn on the upper computer 5 to check the working conditions of the vibrator 1, the governor 1-5, the pressure sensor 1-6, and the single-chip microcomputer control module 1-8. After all checks are correct, connect the vibrator 1, The rod 2, the support frame 3, and the sampling tube 4 are assembled and fixed, and the instrument is slowly put into the water.

[0034] Step 2: During the water entry process of the instrument, the pressure sensor 1-6 continuously detects the water entry pressure signal, reads the signal through the single-chip microcomputer control module 1-8 and converts it into a corresponding depth value and transmits i...

Abstract

The invention discloses a self-controlled vibration sediment sampler, which belongs to the field of measurement and control technology and underwater sediment collection. The sampler is mainly composed of a vibrator, a connecting rod, a sampling tube, a support frame and a control unit. The vibrator provides the power source for the sampler. The support frame is used to ensure the vertical drop of the sampler. The depth of the instrument is detected by the pressure sensor. The single-chip control module sends the signal to the upper computer for display, and at the same time controls the start and stop of the vibrator. The frequency of the vibrator can be adjusted online through the governor. The invention has the beneficial effects of high sampling efficiency, stable operation and small disturbance. The utility model has the characteristics of controllable underwater operation of the sampler, simple structure, convenient installation, and collection of undisturbed layered sediment samples. It is suitable for sediment collection in inland waters such as reservoirs, rivers, and lakes.

Description

technical field [0001] The invention belongs to the field of measurement and control technology and underwater sediment collection, and relates to a sampler used for underwater sediment collection, in particular to a sampler for inland water bottom sediment collection when the water depth is relatively large. Background technique [0002] Bottom sediments are an important part of water bodies in reservoirs and other water sources. Due to the cumulative effect of pollutants over the years, pollutants from river basins accumulate in sediments for a long time, posing a threat to water bodies and their environment. Affected by sedimentary characteristics and pollution sources, the composition and concentration of sediments at different depths are different. With the growth of time, the bottom sediments present a bedding structure. Therefore, it is necessary to study the characteristics of sediments in depth, and the key is to obtain undisturbed stratified sediment samples. [0...
