Abstract
The invention relates to a telescopic fixed-depth water sample collector. The collector is installed in a positioning sleeve and positioned by a cylinder positioning mechanism, a connection part is fixed at the upper part of the collector, and a water drawing mechanism is arranged under the collector; and the positioning sleeve is uniformly installed at the outer side of a rotary table through bolts, a hydraulic piece is arranged at the upper part of the rotary table, and a connection head is fixed under the hydraulic piece. During water sample collection, the rotary table rotates to buckle the connection part and the connection head, the hydraulic piece works to make the collector decline to a certain depth, a pressure generator senses the certain depth and works, and a piston performs upward drawing operation, so that a water sample moves to the underside space of the collector through an underside water drawing port until an underside plug contacts and seals a conical surface. After the water sample is collected, the hydraulic piece makes the collector move upwards into the positioning sleeve and be fixed, and the rotary table rotates to separate the connection head and the connection part, so that water sample collection can be further performed in other regions. By switching the collector through the rotary table, multi-point fixed-depth water sample collection can be realized by means of other combined movements.
