Fixed-point sampling type liquid detection device

Abstract

The invention, which relates to the field of detection devices, discloses a fixed-point sampling type liquid detection device comprising a device box. The lower end of the device box is fixedly connected with an outer detection cylinder; an inner detection cylinder is arranged in the outer detection cylinder; the upper end of the inner detection cylinder is connected with a rotary driving devicemounted in the device box; a movable ring cover is arranged at the lower end of the inner detection cylinder; and an elastic sealing device is arranged on the movable ring cover. A rotary driving device in the device box drives the inner detection cylinder to rotate in the outer detection cylinder. Under the rotary centrifugal effect of the inner detection cylinder, the elastic sealing device at the lower end of the inner detection cylinder is opened under the action of a centrifugal force; liquid at the detection point enters the inner detection cylinder; and the inner detection cylinder isfully and uniformly rotated by the inner detection cylinder and is detected by various detectors in the detector device box. The specific point position of the liquid can be directly detected throughthe device, interference of the liquid at other positions is avoided during detection; and the device is simple in structure, high in practicability and easy to use and popularize.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a liquid detection device for fixed-point sampling.

[0003] With the emergence and continuous upgrading of various liquid detectors, a variety of liquid detection devices have emerged. Liquid detection devices are often equipped with multiple liquid detection instruments with different functions to detect various indicators of the liquid to be detected. The existing liquid detection devices have the following problems during detection: 1. When the detection device detects a specific point, it needs to take a sample in advance, and it will be affected by the liquid outside the point to be measured if it is directly inserted into the liquid; 2. The measured liquid is often a mixed liquid, and the concentration of the detection point is often uneven, resulting in large errors in the detection indicators
