Depth sampler

Abstract

The invention discloses a depth sampler which comprises a bottle body, wherein a baseplate is mounted on the bottle body, a tapered platform-shaped water inlet is formed in the baseplate, the water inlet of the baseplate is butted with the water inlet of the bottle body, a tapered platform-shaped piston is arranged at the water inlet of the baseplate, a base frame is arranged on the baseplate, a spacing hole is formed in the base frame, the piston rod of the piston is placed inside the spacing hole, the piston rod is sleeved with pressure springs, one ends of the pressure springs are fixed on the base frame, the other ends of the pressure springs are fixed on the piston, a miniature submersible motor is further mounted on the baseplate, the rotating shaft of the miniature submersible motor is connected with the piston through a pull rope, a tube rope is further connected to the base frame, and the end of the power cord of the miniature submersible motor penetrates through the tube rope and is connected with a power supply plug. The depth sampler provided by the invention can be used for collecting water body samples in deep, and then carrying out water quality analysis, is free from influences caused by water depth, has a simple structure, is low in manufacturing cost and is very convenient to use.

Description
