Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Depend on Figure 1 to Figure 8 It can be seen that the present invention includes a remote-control-driven hull 1, and the hull 1 is provided with a piston cylinder 2 that is placed vertically and has an open lower end. A water pipe 3, the inner end of the water pipe 3 passes through the upper end of the side wall of the piston cylinder 2 and communicates with it, the outer end is connected with a counterweight 4, the upper end of the piston cylinder 2 is provided with a high-pressure gas cylinder 5, and the valve 6 of the high-pressure gas cylinder 5 Placed in the piston cylinder 2, the piston cylinder 2 is provided with a piston 7 that can only move up and down and cannot rotate. The other end of the air hole faces the valve 6. When the piston 7 moves to the uppermost position, the inner end of the water pipe 3...

Abstract

The invention relates to a stratified sampling device for water, and effectively solves the problem of tedious operation of an existing water sampling device. According to the technical scheme, the stratified sampling device comprises a ship body, wherein a rotatable piston cylinder is arranged on the ship body and wound with a water pipe, the inner end of the water pipe is communicated with the piston cylinder, and the outer end is connected with a balancing weight; a high-pressure cylinder is arranged at the upper end of the piston cylinder; a piston is arranged in the piston cylinder; a ring groove is formed in the excircle surface of the piston, an L-shaped air hole is formed in the middle of the piston, and one end of the L-shaped air hole is communicated with the ring groove; a piston rod is arranged at the lower end of the piston, a rotatable disc is arranged on the left side of the piston rod, and multiple sampling bottles are circumferentially and uniformly distributed on thedisc; a through hole is formed in the left side of the piston, a seal cover is arranged at the upper end of the through hole, a polish rod is coaxially fixed at the lower end of the piston rod, a thread is formed at the lower end of the polish rod, a ratchet and pawl structure is arranged below the polish rod, an internal thread matched with the thread on the polish rod is arranged on the inner edge surface of a ratchet, and the disc can be driven to rotate by rotation of a pawl.

Description

technical field [0001] The invention relates to the field of water body equipment, in particular to a water body layered sampling device. Background technique [0002] The collection of water body samples is an important means of hydrological scientific research and water body management. Accurate and efficient collection of water body samples at different depths is an important basis and premise for the smooth development of various related work. The formation of each layer is obviously different, which is called stratification effect. There are differences in the hydrological, chemical, biological and other information of different water layers. This difference is an important representation of water body characteristics and is also a crucial basic data in various researches. . [0003] The traditional stratified sampling of water body needs to drop different sampling bottles to different depths and then open the sampling bottles for sampling. This sampling method is not ...
