Abstract

The utility model relates to a device for accurately collecting litters in a wet land. The device comprises a square framework, a net bag and a floater, wherein one end of the net bag is fixedly connected to the square framework, and the other end of the net bag is fixedly connected with the floater. The square framework is inserted into the earth, so as to fix the whole device; furthermore, the whole device needs to be in full contact with the ground and is completely closed; the height of the net bag is set according to the actual situation of the wet land; and dead litters can be prevented from flowing out of the device from the water bottom to the water surface.

Description

Accurately collect the device of wetland Litter-fall

Technical field

The utility model relates in a kind of accurate collection aquatic system the device because of the dead Litter-fall of water logging, has important using value in the Study of Material Cycle of aquatic system and system management.

Background technology

In recent years, irrational water resource, soil utilization and climate change make the aquatic system hydrology Dynamic Generation marked changes such as northern area river, wetland: dry season water level low even cutout and longer duration, and the high water stage duration of wet season is short.When therefore anhydrous, plant growth is in great numbers, is easy to be subjected to drowned dying after rainy season set.Entering in decomposable process after plant death, relate to the impact on many aspects such as water body environment, material recycle and energy flows, is research contents important in aquatic system ecology.

The disaggregate approach of existing wetland Litter-fall utilizes the naturally-aged Litter-fall more, adopts the mesh bag method to carry out.Because its constituent of Litter-fall of naturally-aged, structure of matter etc. are all different from the plant that is in vigorous growth, so also there are notable difference in its decomposable process, material recycle.Think more accurately and to inquire into the ecological effect that decomposed by the drowned plant that dies, at first should choose these and be subjected to drowned plant body of dying as analyzing working sample.

And existing method and technology are negligent of paying close attention to the collection that is subjected to the drowned plant body of dying, and most Litter-fall runs off with water body, causes the apparent error of data.In this problem in science, how accurately to collect the Litter-fall on unit area, and then study its decomposable process, nutrient dynamics and be the key of scientific management system on the impact of environment, but currently lack ready-made accurate method.

The utility model content

The utility model provides a kind of device of accurate collection wetland Litter-fall for above-mentioned the deficiencies in the prior art, and very convenient collection is subjected to the drowned plant body of dying.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of device of accurate collection wetland Litter-fall, include quadra, mesh bag and float, and mesh bag one end is fixedly connected on quadra, and the other end is fixedly connected with float.

Preferably, this mesh bag is straight-tube shape.

Preferably, this square framework is 30cm * 30cm * 30cm.

Preferably, this square framework is spliced by four splices, and each splice is made of flat board, steel pipe and iron staff, and weld with steel pipe and iron staff respectively dull and stereotyped both sides, and the side of this steel pipe is provided with vertically is convenient to another dull and stereotyped groove that inserts.

Preferably, this float is sheet, and periphery is connected with mesh bag.

Compared with prior art, the advantage that the utlity model has: this product is complete core structure, quadra is followed closely in water bottom, thereby intactly the plant body of death just can be retained in device fully from the water bottom to the water surface, sample in installing when taking a sample is fetched, and cleans, dries, pulverizes and can measure its quality and nutrient.

In the utility model, quadra inserts in soil, and whole device is fixed, and should keep simultaneously and the contacting fully and sealing of ground; The height of mesh bag can arrange according to local conditions, prevents that dead Litter-fall from flowing out this device from the bottom to the water surface.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of quadra;

Fig. 3 is the structural representation of column.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

The device of a kind of accurate collection wetland Litter-fall as shown in Figure 1 includes quadra 1, mesh bag 2 and float 3, and mesh bag 2 one ends are fixedly connected on quadra 1, and the other end is fixedly connected with float 3.

Quadra 1 as shown in Fig. 2 and 3 is spliced by four splices, each splice is made of flat board 12, steel pipe 11 and iron staff 13, weld with steel pipe 11 and iron staff 13 respectively dull and stereotyped 12 both sides, and the side of this steel pipe 11 is provided with vertically is convenient to another dull and stereotyped groove that inserts.Quadra 1 is 30cm * 30cm * 30cm.

Whole device forms a complete core structure, in use quadra 1 is followed closely at the bottom, therefore from the water bottom to the water surface, dead plant body just can be retained in device fully, sample in installing when taking a sample is fetched, and cleans, dries, pulverizes and can measure its quality and nutrient.

After water level increases to mesh bag 2 and stretches fully, should suitably improve the crystallized ability of fixed frame and the buoyancy of float 3, float 3 can be made as tabular, whole device is changed into remaining silent get final product.

The beneficial effects of the utility model are, can accurately collect to be subjected to drowned Litter-fall of dying in aquatic system, measure that it decomposes dynamically, nutrient dynamics, thereby provide foundation for the scientific management aquatic system.

The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
