Abstract
The utility model discloses a water hyacinth captive breeding mesh, which is spliced by a plurality of hexagonal water meshes consisting of nylon meshes and velcroes. The nylon mesh has good water permeability, high fastness and no easy corrosion; the velcro is sewed at the bottom and side of the nylon mesh, namely the open side of the nylon mesh; the overcircle frame of the nylon mesh is sewed with foam plastics and leads the foam plastics to be uniformly distributed around the nylon mesh; a wood strip is placed in the nylon mesh for fixing the water mesh and the water hyacinth; and the water hyacinth is connected with the wood strip by a rope. The captive breeding mesh has simple structure, convenient manufacturing, convenient salvage, not only effectively controls the wild growth of the water hyacinth, but also takes the advantage of decontamination and protects the natural environment.
Description
Technical field
The utility model relates to the weter hyacinth containment net.
Background technology
Weter hyacinth has another name called Eichhornia crassipes, is aquatic upright or floating herbaceous plant, originates in american torrid zone.Introduce China the thirties in 20th century, promoted as feed for 60～seventies.But since phase early 1990s, the environmental pollution of China is serious day by day, and a large amount of nitrogen of generation, phosphorus nutrition salt and organic pollutant become the nutriment of the mad breeding of weter hyacinth.Particularly culminate at the beginning of late 1990s to 21 century, the situation of weter hyacinth outburst appears in ground such as south China, East China in succession.
In recent years, the weter hyacinth in Huangpu River and riverine medium and small river course is growth trend year by year, almost to the stage that can't contain.Weter hyacinth belongs to the exotic invasive species, and weter hyacinth generally begins breeding by the end of April, and 7,8, breed September in a large number, 8, can hold the flower of purple September.Its breeding in 5 days one, a weter hyacinth can be bred into 250,000 in 90 days.After winter, frost was beaten, the leaf on the water surface rotted, and stem and root continue to survive the winter under water, wait germination in 1 year.Songjiang area weter hyacinth large tracts of land is spread unchecked generally 9, October, this year is because the factor of weather, water plants such as duckweed, weter hyacinth has all done sth. in advance about about two months than former years, just duckweed is controlled by the end of July, weter hyacinth is new in Songjiang, each waters overgrowing of old town, particularly overflow in Zhang Jiabang, the Jing Tang river course, Shen of suburb of Shanghai Songjiang College Town, add that the weter hyacinth in basin, upstream flows into the local area basin with morning and evening tides, weter hyacinth has the gesture of covering the sky and the earth greatly.At this situation, relevant unit starts emergency preplan immediately, salvages weter hyacinth 250 ship tons average every day, and car fortune is 390 tons altogether after compression, and on average about 35--40 ton every day, workload is usual 4--5 times.
Meanwhile, the economic benefit of Eichhornia crassipes is extremely low, and cellulosic shortage makes it should not be used for papermaking; The artificial cost costliness of salvaging, make it lose competitiveness on the price of pig feed ... yet, as everyone knows, Eichhornia crassipes has the ability of well purifying waste water, just can remove 80% nitrogen-containing compound, 40% phosphorus-containing compound in two days, weter hyacinth accumulates in heavy metal, mercury in the fibr tissue simultaneously, eats up bacterium and suspension, remove stink, clean water is put into the downstream.
So we want by the overgrowing of a kind of method containment Eichhornia crassipes, the one side of polluted-water, simultaneously, utilize its good dirty removal capacities, try one's bit, design a kind of device and can control the weter hyacinth overgrowing and can utilize the advantage of its scrubbing to become again to press for for repairing water body.
The utility model content
Technical problem to be solved in the utility model is, a kind of weter hyacinth containment net is provided, and can control the situation that weter hyacinth spreads the overgrowing polluted-water, can utilize the advantage purified water source of weter hyacinth scrubbing again.
In order to address the above problem the technical solution of the utility model is such:
The weter hyacinth containment net, a hexagon network of rivers that is made of jointly nylon wire and velcro is the weter hyacinth containment net, the described hexagon network of rivers is big to utilization of space, and several identical hexagons can seamlessly connect, easily it is salvaged before so just can finishing in earlier stage and handle,, be attached to the method in another hexagon one side therefore adopted and to have opened in the life cycle of weter hyacinth, make its both splicing easily, also convenient the separation.
Described nylon wire good water permeability, firmly the degree height is not perishable; Described velcro is to make the opening edge that is nylon wire in the bottom surface and the side of described nylon wire;
The place of described nylon wire upper ring edge frame sews up foamed plastics, and it is uniformly distributed in around the nylon wire;
Place a batten in the described nylon wire, play the effect of the regulation network of rivers and weter hyacinth, weter hyacinth is linked to each other with described batten, around all the other rely on, its leaf is surfaced, and root is immersed in the water, so just can guarantee the weter hyacinth normal growth with rope.
Operation principle of the present utility model is: be similar to the weter hyacinth stable breeding, promptly use device is controlled at weter hyacinth in a certain comprehensive permeable container and grows.Whole device can move along with current, does not therefore influence the growing environment of weter hyacinth.Treat that Eichhornia crassipes closely covers with container, we can connect another same hexagon network of rivers, are attached thereto.And open " door " on one side, make weter hyacinth naturally long in second container.Shut " door " in good time, pack up first hexagon container and promptly finished salvaging.This process constantly repetitive cycling is carried out.
The beneficial effects of the utility model are that it is convenient to salvage, and effectively controls the weter hyacinth overgrowing, has protected natural environment, simple in structure, easy to make.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the vertical view of the utility model weter hyacinth containment net;
Fig. 2 is the flow chart of the utility model operation principle.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the weter hyacinth containment net comprises nylon wire 1 and velcro 2, and described nylon wire 1 and velcro 2 constitute a hexagon network of rivers, and the splicing of a plurality of hexagons network of rivers is promptly constituted the weter hyacinth containment net; The described hexagon network of rivers is big to utilization of space, and several identical hexagons can seamlessly connect, easily it is salvaged before so just can finishing in earlier stage and handle in the life cycle of weter hyacinth, therefore adopted one side has been opened, be attached to the method in another hexagon, make its both splicing easily, also convenient the separation.
