An instrument for collecting and measuring sedimentation in a water-fluctuation zone

Abstract

The invention provides an accumulated sediment collecting tester for a hydro-fluctuation belt. The tester includes a fixing column, multiple sampling cylinders are installed on the fixing column, a supporting disc is installed on the fixing column, and multiple fixing grooves are formed in the supporting disc and distributed in the circumferential direction of the supporting disc; openings are formed in the tops of the fixing grooves, the sampling cylinders are placed in the corresponding fixing grooves from the corresponding openings, a detachable sealing cover is arranged on the top of eachsampling cylinder, and a fastening mechanism used for fastening the corresponding sampling cylinder is installed on each fixing groove; a sampling cylinder pulling rope for pulling out the corresponding sampling cylinder from the corresponding fixing groove is arranged on the top of each sampling cylinder, and a sealing cover pulling rope for opening the corresponding sealing cover is arranged oneach sealing cover. The tester is simple in structure, and accumulated sediment can be collected within a certain time period according to actual demands; the tester has the advantages of a stable structure and firm support.

Description

technical field [0001] The invention mainly relates to the technical field of sedimentation collection in a hydrofluctuation zone, in particular to an instrument for collecting and measuring sedimentation in a hydrofluctuation zone. Background technique [0002] The ebb and flow zone is the seasonal water level fluctuation area formed after the operation of the reservoir. It is of great significance to study the sediment deposition in the water-fluctuation zone. The traditional sedimentation measuring instrument generally only adopts a fixed rod, and a sampling cylinder is installed on the fixed rod for use. However, the measuring instrument with traditional structure has the following problems in actual use: it can only measure the sedimentation situation of one cycle at one time, and cannot measure the sedimentation situation in sections within one cycle, that is, it cannot measure the sedimentation situation of a certain period in one cycle. The specific sedimentation s...

Problems solved by technology

However, the measuring instrument with traditional structure has the following problems in actual use: it can only measure the sedimentation situation of one cycle at one time, and cannot measure the sedimentation situation in sections within one cycle, that is, it cannot measure the sedimentation situation of a certain period in one cycle. The specific sedimentation situation in a period of time; the fixed rod of the traditional structure is generally directly inserted into the fading zone, and the support strength is not enough. During the process of water level fluctuation or as the amount of sedimentation increases, it is prone to tilting and dumping and so on
