Technical Field
The utility model relates to the technical field of stream ecological resource investigation, in particular to a stream benthonic animal sample collection device.
Background
Benthic organisms are an important group of life-forms in aquatic organisms, and stream benthic animals play a vital role in the stream ecosystem. They are the primary food sources for many fish and other aquatic animals, and also participate in the breakdown of organic matter, converting it into usable nutrients, thereby driving the circulation of matter and energy flow of the stream ecosystem. Benthonic animals also help to purify water by feeding and decomposing organic matter, reducing the likelihood of plankton and algae overgrowth. Some benthonic animals are able to stabilize river sediment, thereby reducing the re-suspension of sediment. In addition, certain benthonic animals are very sensitive to environmental changes and pollution, and therefore they are considered indicators of ecological health and water quality. Its presence or absence may reflect the health of the stream. Thus, benthonic animals are of great importance in the evaluation of stream health, providing us with direct information on stream environmental conditions. Protecting benthonic animals and their ecological environment is critical to maintaining stream health and the stability of the ecosystem.
Because the substrate of stream mainly is silt or rubble bottom, flat (soft bottom), traditional cable primary net or triangle trawl can not effectively get deep into the bottom and gather when gathering stream benthonic animal, inform because stream rubble and silt are too much, the sampling in-process washs loaded down with trivial details, and efficiency is lower, and causes the damage to benthonic animal easily.

Detailed Description
For a better description of the objects, technical solutions and advantages of the present utility model, the present utility model will be further described with reference to the following specific examples.
Example 1
The utility model provides a stream benthonic animal sample collecting device, which is shown in figures 1-3, and comprises a frame body 1, a collecting net 3 and a collecting net 4, wherein an opening 11 is arranged on the frame body 1, a detachable steel pipe handle 8 is arranged at the upper part of the upper end of a top frame of the frame body 1, guide plates 12 are arranged on two sides of the frame body 1, and the guide plates 12 are arranged on a frame through hinges and can rotate. The guide plate 12 is connected to the steel pipe handle 8 through a steel wire rope, the direction of the guide plate 12 can be changed by operating the steel wire rope according to the water flow condition during sampling, the resistance of sampling is reduced, and the phenomenon that the water flow washes away the sample which does not enter the collection net 3 is avoided.
The sample of the benthonic animal at the time of collection enters the collection net 3 through the opening 11. The collection net is nylon material, and the stiff end is double-deck thickening, through rivet fixation. The rear end of the opening 11 is connected with the collecting net 3 and the collecting net 4, the bottom of the collecting net 3 is provided with the filter screen 2, and the collecting net 3, the filter screen 2 and the collecting net 4 are detachably connected, such as a locking bolt, a zipper and the like. The pore size of the filter screen 2 is larger than that of the collecting net 3 and the collecting net 4. The contact position of the opening 11 and the bottom of the stream is provided with a plurality of bulges 5 which can be inserted into the bottom, and the bulges 5 are fixed in reserved holes at the edge of the opening 11 by screws before sampling. The protrusions 5 are saw-tooth-shaped. The protrusion 5 is inserted obliquely into the bottom of the stream, and the oblique direction is consistent with the moving direction during sampling. The contact position is provided with a tilting plate 6 extending towards the inside of the collecting wire 3, along which plate the sample enters the collecting wire 3 during sampling. Preferably, a plurality of protrusions 5 are arranged on both sides of the contact position between the opening 11 and the bottom of the stream, and the inclined plate 6 extends outwards to the middle of the contact position between the opening 11 and the bottom of the stream, and the inclined plate 6 is inserted into the bottom along with the protrusions 5 like a spade or a shovel.
