Embodiment Construction

[0019] In view of the fact that the benthic organism collectors in the prior art are not convenient for collecting benthic organisms according to demand in medium-shallow water bodies, the inventor conceived a benthic organism collector. The benthic organism collector comprises a collection box, a piston, a pull rod and a hollow collection box rod, the piston is placed in the collection box, one end of the collection box is provided with an opening and the other end of the collection box is connected to the collection box rod, and the collection box rod covers The pull rod is provided with a scale, one end of the pull rod is connected to the piston and the other end of the pull rod is placed outside the end of the collection box rod away from the collection box. When using the benthic organism collector to collect benthic organisms living in the mud at the bottom of the water body in a medium-shallow water body, the opening of the collection box can be inserted into the mud at ...

Abstract

The invention relates to the field of benthic organism sampling, in particular to a benthic organism sampler which comprises a sampling box, a piston, a pull rod and a hollow sampling box rod, wherein the piston is arranged in the sampling box; an opening is formed in one end of the sampling box; the other end of the sampling box is connected with the sampling box rod; the sampling box rod sleeves the pull rod; graduations are marked on the pull rod; one end of the pull rod is connected to the piston; the other end of the pull rod is placed at the outer part of one end, far away from the sampling box, of the sampling box rod. When the benthic organism sampler is used for sampling benthic organisms surviving in soil at the bottom of the water body in a middle-shallow water body, the moving distance of the piston in the sampling box is read out conveniently by observing the graduations on the pull rod, so that the sampling depth is controlled. Since the cross-sectional area of the opening of the sampling box is given, the current sampling amount can be known easily by reading out the moving distance of the piston in the sampling box, and the sampling can be performed relatively accurately according to the quantity demanded.

Description

technical field [0001] The invention relates to the field of benthic organism collection, in particular to a benthic organism collector. Background technique [0002] At present, there are many types of benthic collectors on the market. However, in the process of studying the diversity of benthic organisms in water bodies, it is often necessary to collect them in some medium-shallow water channels, shallow water channels, channels with narrow water flow, or shallow water lakes. To collect benthic organisms living in mud, existing benthic organism collectors may not be suitable for sampling in such an environment, and they cannot accurately control the collection amount. That is to say, the benthic organism collector in the prior art is not convenient for collecting benthic organisms more accurately according to demand in medium-shallow water bodies. Contents of the invention [0003] The object of the present invention is to provide a benthic organism collector to improve...
