Abstract

The invention discloses a sampling pump with an automatic angle change. The sampling pump comprises an operation board and a water quality sampling pump, wherein the operation board includes a storage battery, a step motor I, a step motor II, two take-up pulleys and two telescoping rods. The storage battery is located in the operation board; the step motors are connected to the storage battery in parallel; the two take-up pulleys are fixedly mounted on the step motor I and the step motor II, respectively; the two take-up pulleys are fixedly mounted at the rear ends of the two telescoping rods, respectively; and pulleys are installed at the front ends of the telescoping rods, respectively. The water quality sampling pump includes a step motor III, a sealed housing, a worm gear, a worm pricking pin tube, and a vacuum sampling tube, wherein the step motor III is installed in the sealed housing; the worm gear is fixed on the step motor III through a transmission shaft; and a worm pricking pin is connected to the worm gear and is fixed in a nut arranged at the upper end of the vacuum sampling tube. The beneficial effects of the invention are that automatic water sampling can be realized through the sampling pump and the accuracy of the sampling result can be ensured. A motor control rope is added on the sampling pump; multi-angle change of water sampling can be realized; and requirements of water sampling in deep water and shallow water can be realized.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an automatic angle-variable sampling pump. Background technique [0002] At present, most of the water sample collectors are closed cylindrical structures. Due to the unsatisfactory design of the water inlet structure and poor sealing performance, it is difficult for these water collectors to avoid the mixing of water samples taken from different layers of water, resulting in water samples The monitoring accuracy cannot be achieved, which increases the difficulty of monitoring work. In addition, the structure and material of the cylinder are not suitable for deep water sampling. [0003] Moreover, the angle cannot be changed during the sampling process and cannot be adapted to the use of different water areas at the same time, and automation cannot be realized during the sampling process. Contents of the invention [0004] Aiming at the deficiencies of the prior art, t...
