Problems solved by technology

[0005] 1. In-situ measurement cannot be realized, and it is necessary to collect samples of submerged plant leaves into the detection container. This process will easily lead to changes in the natural environment near the submerged plant leaves, resulting in a discrepancy between the dissolved oxygen of the submerged plant leaves and the actual situation. match;
[0006] 2. Only one dissolved oxygen micro-optical probe can be controlled at a time to detect the dissolved oxygen at a certain height of a certain position of the leaves of submerged plants. For the dissolved oxygen at other heights of the leaves of submerged plants, it can only be obtained through multiple measurements. However, multiple measurements will have a large time span and cannot reflect the real situation;
[0007] 3. For a single measurement, only one side of the submerged plant leaf can be selected for measurement, and the dissolved oxygen on the front and back sides of the leaf cannot be measured at the same time.

Abstract

The invention discloses a device for detecting dissolved oxygen at different heights of submerged plant leaf and water interface simultaneously through in-situ measurement. The device comprises a dissolved oxygen micro-optrode main unit connected with multiple detection probes, wherein probe pins used for detecting dissolved oxygen can extend out of the detection probes; the detection device further comprises a leaf clamp; the leaf clamp comprises an upper chuck, a lower chuck, an articulated shaft and a clamp handle, a plurality of water passing cavities penetrating through the chuck backs and the chuck surfaces are formed in the upper chuck and the lower chuck, and a plurality of inserting slots horizontally extending towards the corresponding chucks are formed in the upper chuck and the lower chuck; the detection device comprises a plurality of inserting slices, probe slots are formed in the inserting slices, the detection probes can be placed in the probe slots to be fixed, the inserting slices can be inserted and fixed in the inserting slots, and the probes extending out can be located in different water passing cavities by adjusting the depths of the inserting slices inserted into the inserting slots. The device has the advantages that dissolved oxygen at different heights of the front sides and back sides of submerged plant leaves can be measured simultaneously, repeated tests are avoided and time is saved.

Description

technical field [0001] The invention relates to the technical field of dissolved oxygen detection equipment, in particular to a detection device and a detection method for simultaneous in-situ measurement of dissolved oxygen at different heights of submerged plant leaf-water interfaces. Background technique [0002] Dissolved oxygen micro-optopole is a one-dimensional microprobe technology that can realize the measurement of dissolved oxygen concentration at a certain point of submerged plant leaves. It is an optical fiber information exchange sensor based on the principle of fluorescence quenching. Since oxygen is the natural quencher of some fluorescent indicators, it makes an oxygen sensitive fluorescent indicator into an oxygen sensing film and couples it to the end of the optical fiber. It uses a high-brightness light-emitting diode As a light source and miniature photodiode detection system, the oxygen concentration is determined through the optical fiber conduction fl...
