A double-barrel suspended sediment and water sample sampler

Abstract

The invention discloses a double-barrel suspended sediment and water quality sample sampler, which belongs to the technical field of water environment monitoring and analysis and hydrological sediment testing. The sampler is provided with two sampling cylinders, which are installed on both sides of the installation body, two cylinder covers are installed at both ends of the sampling cylinder, the two cylinder covers of each sampling cylinder are connected by a second spring, and the cover plate is fixedly installed on the On the top of the installation body, the lateral block of the door closing body is slidably arranged in the sliding cavity of the installation body, the vertical block is slidably inserted into the sliding hole of the installation body, the orientation block is movably arranged at the top of the vertical block, and the two ends of the first spring They are respectively connected to the bottom of the orientation block and the sliding hole, the door closing pin is slidably inserted in the guide hole of the installation body, and protrudes from the guide hole. on the closing latch. The present invention can be carried out automatically, can ensure the capacity and quality of sampling samples, and can adapt to sampling work under different conditions.

Description

technical field [0001] The invention belongs to the technical fields of water environment monitoring and analysis and hydrological sediment testing, and in particular relates to a double-barrel suspended sediment and water quality sample sampler. Background technique [0002] At present, the methods used by various departments in our country to obtain hydrological sediment and water quality samples are generally to first row the boat to a certain water area, and then use sampling containers such as bottles or barrels to obtain a certain amount of sediment and water quality samples in different areas. [0003] In the process of realizing the present invention, the applicant finds that there are following deficiencies in the prior art: [0004] The hydrological sediment and water quality sample acquisition methods in the prior art are mostly carried out manually or semi-automatically, which are only suitable for sampling a small amount of samples under the conditions of low fl...

AI Technical Summary

Problems solved by technology

[0004] The hydrological sediment and water quality sample acquisition methods in the prior art are mostly carried out manually or semi-automatically, which are only suitable for sampling a small amount of samples under the conditions of low flow rate and medium water depth rivers. Sampling a large number of samples is time-consuming and laborious, and there are certain safety hazards. If the water flow is slightly larger, the door of the sampling container cannot be closed, and the quality of the sample taken cannot be guaranteed.
