Description

Water quality sampler for aquaculture Technical Field The utility model belongs to the technical field of aquaculture, and particularly relates to a water sampler for aquaculture. Background Aquaculture is an industry for cultivating aquatic economic animals and plants by manually controlling water area environments (such as ponds, lakes, factory workshops and the like), and aims to meet the requirements of aquatic products and promote green agricultural development. The method is characterized in that natural ecological conditions are simulated, efficient production is realized through scientific management, and in the process, water quality sampling detection is a key link for guaranteeing production benefits and ecological safety. In the prior art, when detecting the quality of water of aquatic products, need sample the quality of water of different degree of depth, but current device needs many times operation just can accomplish, unable disposable sample, and quality of water sampling efficiency is lower. Therefore, the utility model provides a water quality sampler for aquaculture. Disclosure of utility model In order to make up for the deficiencies of the prior art, the problems presented in the background art are solved. The water quality sampler for aquaculture comprises a column body, wherein the top end of the column body is fixedly connected with a disc, a group of first cavities are formed in the column body, a group of first through holes are formed in the outer side wall of the column body and are communicated with each other, the first through holes are close to the lower portion of the bottom end of the first cavities, a piston is connected in the first cavities in a sealing sliding mode, the pistons are connected through lifting columns, the top ends of the lifting columns penetrate through the column body and the disc, the lifting columns move up and down through lifting pieces, a first pipeline is fixedly connected to the outer side wall of the column body, the first pipeline is communicated with the first through holes, and a handle rod is fixedly connected to the outer side wall of the disc.
