Abstract
The invention belongs to the field of environmental engineering and environmental ecology, and particularly relates to a simple device for removing submerged plants in bottom sediments of a shallow lake by utilizing water pressure. The simple device comprises four main parts, i.e., a suctioning device, a water spraying device, a collecting device and a fixed device, and can be arranged on any ship body. When a self-sucking pump works, lake water is sucked by a filter net, enters a water suctioning pipe, and then enters a water guiding pipe after flowing through a connecting pipe, a fixed rod and a connecting arm. A pressurized water column is sprayed out along a spraying nozzle to wash the bottom sediments of a surface layer, so that the submerged plants are washed out of a bottom-sediment layer and are collected by a collecting net. The simple device is not limited by the areas of the ship body and a water body, is economic and high-efficiency, can remove the submerged plants completely and is convenient for promotion.
Description
Technical field
The invention belongs to Environmental Engineering, environmental ecology field, particularly a kind of easy device of utilizing hydraulic pressure that submerged plant in the shallow lake bed mud is removed.
Background technology
Large-scale submerged plant plays key effect to the ecological characteristic of shallow lake, through growth, growth, death and the decomposable process of himself, the nutritional status and the nutrition circulation of water body is exerted an influence.Present stage, the submerged plant of domestic and international a plurality of lake and marshlands spreads present situation by play-by-play, and the method that excessively spreads submerged plant for control mainly comprises control lake nutriment level and two aspects of mechanical harvesting.Wherein, mechanical harvesting is because characteristics such as its ecological safety, instant effect and extensively being adopted.The patent No. is that the utility model patent of ZL 200320122835.1 has been announced a kind of water plant of stepped type under water reaping apparatus; Form by box body device, mowing-apparatus, hydraulic means, four major parts of running gear, be adapted to the harvesting operation of environment such as bed mud and swamp land under water; The patent No. is that the patent of invention of ZL03820328.6 has been announced a kind of harvester waterborne, comprises major parts such as waterborne vessel, harvester waterborne, arm, control device, is applicable to the harvesting operation of the big water surface; Application number is that 201110144606.9 patent of invention has announced that a kind of shoal combined type drives water plant harvesting ship; Comprise parts such as hull, drive system, gathering-device, storage device, transport, driving running gear, control device, be applicable to profundal zone, shoal area, swamp land effect.Mostly the reaping apparatus of present stage is harvesting ship shape formula, mainly is applicable to the submerged plant harvesting operation of the big water surface, is difficult in irrigation canals and ditches and river course, gather in; Reaping apparatus is main with the blade form mainly, is difficult to realize the collection of root system, can not eliminate the accumulation of root system at lakebed; Simultaneously, harvesting ship structure relative complex needs to drop into the construction that a large amount of financial resources are used to gather in ship early stage, promotes in vast rural area to have certain limitation.
To the limitation of original method, the invention provides a kind of water jet scavenge unit that utilizes hydraulic pressure that submerged plant is removed, this apparatus structure is simple, and is economic and practical, can submerged plant be carried out complete collection, is convenient to promote.
Summary of the invention
The objective of the invention is to: according to the deficiency of existing submerged plant reaping apparatus; A kind of water jet submerged plant scavenge unit that can on any motor-driven or wooden boat, use is provided; Realize freely gathering in of the interior submerged plant of shallow lake, especially bay, effectively prevent the biofouling in lake.
The present invention is made up of aspirator, water injector, gathering-device and four major parts of fastening devices.Lake water gets in the water injector after aspirator is drawn and pressurizeed, and by the pressurization water column of shower nozzle ejection submerged plant is gone out sediment layer, by gathering-device plant integral body is collected.Because the current in the pipe have bigger pressure, are fixed on the hull through fastening devices.
Aspirator is made up of self priming pump, suction water pipe and screen pack.Be convenient open-air the use, self priming pump is selected the diesel oil self priming pump, and its power is in time adjusted according to the soft degree and the depth of water of bed mud.Suction water pipe one end links to each other with self priming pump, and an end links to each other with screen pack, and the water inlet bore of aperture and self priming pump is complementary, and length is positioned at the height more than the following submerged plant layer of the water surface to guarantee screen pack between 2-3m.Water injector is made up of aqueduct, solid hopkinson bar and shower nozzle.When the current of pressurization after linking arm gets into aqueduct, through the shower nozzle on the aqueduct lakebed top layer bed mud is washed away.Current can produce reaction force upwards in the process of spraying, therefore in the middle of aqueduct, embed solid hopkinson bar, increase gravity, the reaction force that receives with the balance aqueduct.Solid hopkinson bar is fixed in aqueduct inside through the locking cap at aqueduct two ends.Gathering-device is made up of the support of collecting net net, collecting net fixed bar and collecting net.The length of collecting net fixed bar is greater than aqueduct 1m, effectively to control the submerged plant that floats in the water body.The support of collecting net net is used for fixing collecting net, and collecting net selects for use common fishing net to make, aperture 3-5cm.Fastening devices is made up of support and retainer ring, and retainer ring can free folding, is convenient to the dismounting of fixed bar.
The present invention has the following advantages owing to take above technical scheme:
1, can place on any power ship or the wooden boat and use, not receive the restriction of hull;
2, can be according to water channel width adjustment device length, even in narrow water channel, still can use;
3, can plant overground part and root system be removed from bed mud fully, farthest reduce the biofouling in lake;
4, this equipment is formed simply, and early stage, economic input was less, helped promoting the use of in vast rural area.
