Embodiment 1

[0053] A specific embodiment of the present invention discloses a monitoring device for isotope fractionation effect of modern sediments in caves, such as Figure 1 to Figure 3 As shown, it includes a flat plate 1, which is provided with a plurality of protrusions, and a water flow channel is formed between the protrusions; wherein, the protrusions include a main protrusion 2 and at least one secondary protrusion 3, and the main protrusion 2 is the drip center Point position, the main protrusion 2 is preferably arranged at the center of the plate 1, the top surface of the main protrusion 2 is used to receive the dripping water, and the main protrusion 2 is surrounded by a plurality of secondary protrusions 3 for receiving splash water . Wherein, the plate 1 is a smooth glass plate or a frosted glass plate.

[0054] Considering that the positions where the dripping water falls on the plane after splashing are distributed in a circle, the secondary protrusions 3 are arranged at...

Embodiment 2

[0068] Another specific embodiment of the present invention discloses a method for monitoring the isotope fractionation effect of modern cave deposits, using the monitoring device for isotope fractionation effect of modern cave deposits in Example 1, specifically comprising the following steps:

[0069] Step 1: Place the monitoring device for the isotope fractionation effect of modern sediments in the cave under the dripping device, so that the dripping port of the dripping device is aligned with the center of the main protrusion 2 . Place the plate 1 at the position of the research point, keep the plate 1 level, and the dripping water can directly fall on the main protrusion 2 located in the center of the plate 1 dripping water.

[0070] Step 2: Turn on the dripping device to conduct a preliminary drip test. The dripping water on the main protrusion 2 will splash. Adjust the distance between the secondary protrusion 3 and the center of the main protrusion 2 according to the dr...

Abstract

The invention relates to a monitoring device and monitoring method for the isotope fractionation effect of cave modern sediments and belongs to the technical field of karst water monitoring. Accordingto an an existing cave modern sediment isotope fractionation effect monitoring device, a flat ground glass sheet is adopted, and as a result, sediment formation cause types cannot be distinguished, the isotope fractionation effect monitoring result of a calcium carbonate sediment is inaccurate, and the isotope fractionation effect of the cave modern calcium carbonate sediment cannot be accuratelydetermined. With the monitoring device and monitoring method of the invention adopted, the above problems can be solved. The monitoring device for the isotope fractionation effect of the cave modernsediments comprises a flat plate; a plurality of protrusions are arranged on the flat plate; and water flowing channels are formed among the protrusions; the protrusions comprise a main protrusion andauxiliary protrusions; the main protrusion is a dripping center point position; the top end face of the main protrusion is used for receiving dripping water; and the auxiliary protrusions are arranged on the periphery of the main protrusion and used for receiving splashing water. According to the monitoring device and monitoring method of the invention, the isotope fractionation effect and influence factors of the cave modern calcium carbonate sediments can be accurately interpreted.

Description

technical field [0001] The invention relates to the technical field of karst water monitoring, in particular to a monitoring device and a monitoring method for the isotope fractionation effect of modern cave sediments. Background technique [0002] At present, the current collection of modern calcium carbonate deposits in caves mainly uses flat ground glass sheets. The monitoring results show that with the change of the distance from the drip point, the calcium carbonate deposits δ 18 O and delta 13 Fractionation of different degrees appears in the C value. Fractionation is thought to result from changes in drip saturation, kinetic fractionation, and evaporation effects. After years of research, the inventor found that in actual monitoring, when dripping water from a cave falls onto a flat frosted glass sheet, the dripping water will splash in all directions, forming deposits not only at the center of the dripping water, but also at different positions from the center of t...
