Zusammenfassung: | The invention discloses a sampling device for precise water depth measurement sediment analysis. The device comprises a sampling chamber, a lowering rope is correspondingly arranged on the outer sideof the upper end of the sampling chamber, and a counter weight is correspondingly arranged on the outer side of the lower end of the sampling chamber; a sealing chamber is correspondingly arranged onthe inner side of the upper end of the sampling chamber, a driving device is correspondingly arranged in the sealing chamber, and a driving rod of the driving device vertically extends downwards intothe sampling chamber and extends downwards to be provided with a sealing plate. When the sampling device is put down, the driving device drives the sealing plate to be pressed on the bottom plate of the sampling chamber; therefore, all the sampling holes are blocked; the lowering rope and a balance weight are matched to be lowered to a specified depth; at the moment, the driving rod and the sealing plate are controlled by t |
