Problems solved by technology

[0003] As far as the sampling device is concerned, the common method currently used is to collect water with a counterweight bucket. In this way, only mixed water samples can be collected, and fixed water level sampling cannot be performed, or when fixed water level sampling is performed, the operation is particularly cumbersome and the positioning is inaccurate. question
For underwater sand sampling, currently most projects need to use special geological drill pipes for underwater sampling, which requires a lot of auxiliary equipment, and the equipment installation and operation process are very complicated, which is not conducive to efficient underwater sampling
At the same time, the above-mentioned sampling device has a single sampling function, and does not have two sampling functions of simultaneously and accurately collecting water samples or / and sand samples.

Abstract

The invention discloses a multifunctional underwater water sampling and sand sampling device. The device comprises a sampling barrel of which the bottom part is provided with a counterweight body, wherein an inner chamber of the sampling barrel is connected to an inner chamber of the counterweight body through a first one-way valve and a second one-way valve; an infrared water level detector is mounted in the sampling barrel, and a sampling window is arranged on the sidewall of the sampling barrel; a supporting frame is arranged on the top part of the sampling barrel; the supporting frame andthe sampling barrel are correspondingly connected to a bearing stranded wire; the inner chamber of the counterweight body is divided into a water sample collecting chamber and a sand sample colletingchamber; the sidewall of the water sample collecting chamber is a water permeating net pore wall; the inner chamber of the sampling barrel is communicated with the water sample collecting chamber through the first one-way valve; a sand sampling pipeline is arranged in the sand sample collecting chamber; an upper port of the sand sampling pipeline is connected to the inner chamber of the sampling barrel through the second one-way valve; a lower port of the sand sampling pipeline extends out of the bottom wall of the sand sample collecting chamber; an underwater sound wave generator, a receiverand an optical grating water level detector are arranged in the sand sample collecting chamber; a drilling rod is arranged in the sand sampling pipeline; a drill bit extends out of the lower port of the sand sampling pipeline; and vortex blades are arranged on the drilling rod. The device has the sand sample and water sample collecting functions.

Description

technical field [0001] The invention relates to the fields of hydrology, geological investigation, and water resource exploration, in particular to a multifunctional underwater water mining and sand mining device. Background technique [0002] At present, in hydrological survey, water resources survey and geological survey, it is often necessary to collect certain water samples or water samples with fixed water levels for indoor or field tests; when sampling and investigation of underwater geological conditions are required, sand samples are also required. In particular, underwater sand sampling is required. [0003] As far as the sampling device is concerned, the common method currently used is to collect water with a counterweight bucket. In this way, only mixed water samples can be collected, and fixed water level sampling cannot be performed, or when fixed water level sampling is performed, the operation is particularly cumbersome and the positioning is inaccurate. ques...
