Problems solved by technology

However, for grass-type lakes, these mud collectors cannot collect submerged plants and surface mud samples at the same time, or the collection effect is very poor
All in all, the current collectors for benthic fauna can no longer meet the needs of collecting benthic fauna in grass-type lakes in the current research on aquatic ecosystems

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0032] Such as Figure 1 to Figure 7 As shown, the present invention proposes a grass-type lake benthic animal collector, comprising a shell 1, a net bag 2, a load-bearing clamp 3, a double stay rope 4 and a cutting board 10;

[0033] The shell 1 is made of stainless steel, and the shell 1 is a hollow structure. The front wall and the rear wall of the shell 1 are hollow with interlayers. The four legs on the upper part of the shell 1 are provided with pull rings 6. The left two pull rings 6 are equipped with left shell steel wire pull wires 501 , the right casing steel wi...

Abstract

The invention discloses a grass-type lake benthonic animal collector, which comprises a shell, a cutting plate, a net bag, a load-bearing clamping plate and a double pull rope. The shell is fixed below the net bag, the upper portion of the shell is connected with the double pull rope, the cutting plate is installed in the shell, and the outer portion of the shell is connected with the load-bearing clamping plate. The cutting plate can be matched with the double pull rope to complete cutting of surface sediments. The net bag can prevent the benthonic animals from escaping in the sample collection process, and can also be used for primary screening of the samples. The load-bearing clamping plate can determine the thickness of surface sediments collected by the collector according to scale marks outside the shell. The double pull rope is separately connected with the shell and the cutting plate and completes descending and ascending operations of the collector. The grass type lake benthonic animal collector is convenient to operate, and can be used for simultaneously collecting submerged plants in a grass-type lake and benthonic animals in surface sediments, and improving the sampling accuracy and efficiency.

Description

technical field [0001] The invention relates to the field of water ecological environment, in particular to a collector for benthic animals in grass-type lakes. Background technique [0002] Benthic animals are groups of animals that live at the bottom of a body of water. Except for settled and active life, the forms of habitat are mostly fixed on hard substrates such as rocks and buried in soft substrates such as sand. In addition, there are those attached to the body surface of plants or other benthic animals. Most benthic animals live in the bottom mud for a long time, and have the characteristics of strong regionality and weak migration ability. They usually have little ability to avoid environmental pollution and changes, and the destruction and reconstruction of their communities take a relatively long time; and most species of individuals At the same time, different types of benthic animals have different adaptability to environmental conditions and tolerance and se...
