A mechanical recyclable automatic water sampling device

Abstract

A mechanical recyclable automatic water sampling device, including a sampler, the sampler includes a housing and a buoyancy cover; a buoyancy cover is provided on the upper part of the housing, and a sealing ring I is provided and fixedly connected between the housing and the buoyancy cover; There is a partition in the middle of the shell, and the partition is provided with a water inlet hole, and the partition is connected with the shell through screws; a water-absorbing rubber ring is installed under the partition, and a wedge is arranged on the outer periphery of the water-absorbing rubber ring. A sliding pin is installed in the side wall at the bottom of the housing, a base is provided under the water-absorbing rubber ring, a water inlet is provided at the upper end of the base, and a water inlet is provided at the side wall of the middle part of the base; between the housing and the base and A sealing ring III is installed under the limit pin Ⅰ; a cable is coiled in the upper part of the base, and a liner is installed under the cable. One end of the cable is connected to the partition, and the other end of the cable is connected to the liner. Inertia blocks, counterweights are installed at the bottom of the base through screws. The present invention ensures that the present invention sinks into the bottom of the water upright, and ensures that the sampler floats out of the water.

Description

technical field [0001] The invention belongs to the field of hydrogeology, and relates to a mechanical device capable of automatically collecting bottom water samples in a research area in water, in particular to a water sampling device that automatically floats out of the water after collecting water samples and can realize water surface positioning, and is convenient for salvage and recovery . Background technique [0002] With the rapid development of economy and society, the development and utilization of rivers, rivers, lakes, seas and groundwater resources have increased rapidly, and at the same time, the pollution and damage to water resources have also further increased. It is imperative to carry out water pollution investigation and strengthen water resource prevention and control. At present, most of the existing underwater sampling devices are electromechanical equipment, which require energy supply, and have the problems of large volume, complicated operation an...
