Embodiment Construction

[0018] The multifunctional sampling shovel of the invention is used for collecting samples of attached organisms such as freshwater shellfish in water pipelines and samples of benthic organisms in shallow water bottom mud. The multi-functional sampling shovel effectively controls the opening and closing of the cover through the cover closing spring and the control cable, so as to realize the protection of the collected samples and avoid the loss of samples during the collection and recovery process, and adjust the handle angle Bolts are used to control the angle between the handle and the sampling chamber to achieve the most labor-saving and comfortable sampling process.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

Abstract

The present invention relates to an aquatic organism sampling device, and specifically is a sampling shovel for easy acquisition of freshwater mussels attached in water pipes and benthic organisms in shallow water sediments. The sampling shovel is composed by a sampling container, an open and close device for a sampling container cover, and an angle adjustment device. By a self-closing device and a pulling open device, the open and the close of the sampling container can be controlled, and the angle between a holding rod and the sampling container can be adjusted. The sampling shovel of the invention has the advantages of simple structure, convenient operation, high controllability, reliable and flexible operation, and low cost. The sampling shovel can be applied for the operation processes of acquiring the freshwater mussels attached in the water pipes and such unavailable samples at high places, and sampling the benthic organisms in the shallow water sediments.

Description

technical field [0001] The invention relates to a sampling device for aquatic organisms, in particular to a sampling shovel which is convenient for collecting attached organisms such as freshwater shellfish in water pipelines and benthic organisms in shallow water bottom mud. Background technique [0002] In recent years, the research and control of freshwater shellfish have been paid more attention. Freshwater shellfish can grow in large quantities in the freshwater environment, and a large number of attachments in the water pipeline will increase the resistance of water delivery, corrode the pipe wall, affect water quality, interfere with the natural ecosystem, and cause ecological disasters. As a precautionary measure, samples must be taken in water pipelines. However, it is difficult to collect samples at the top of the pipeline in a water pipeline with a diameter of several meters. At present, there is no corresponding collection tool, and the sample will be lost durin...
