Water hyacinth salvage device and method

Abstract

The invention discloses a water hyacinth salvage device and method, and belongs to the field of water salvage. The water hyacinth salvage device comprises a salvage body, buoys connected to the salvage body, horizontal connecting ropes on the end parts of a plurality of skeletons for connecting the adjacent skeletons in sequence and fishing nets fixed to the skeletons and the horizontal connecting ropes; the salvage body comprises the multiple skeletons arranged in parallel; the skeletons on the two end parts of the salvage body are both connected to draw cords, the two ends of the skeletons on the end parts are separately connected to the two ends of the draw cords, and the length of the draw cords is greater than the length of the skeletons; and the buoys are mounted on the skeletons. The water hyacinth salvage device and method have the advantages such as high salvage efficiency, small occupied space, cost saving, simple operation and environmental protection.

Description

technical field [0001] The invention belongs to the field of water area salvage, and in particular relates to a water hyacinth fishing device and a water hyacinth fishing method thereof. Background technique [0002] Water hyacinth, also known as water hyacinth, is a floating aquatic plant with both asexual and sexual reproduction functions. It has a strong ability to restore and disperse populations, and can reproduce rapidly under suitable conditions. The rapid reproduction of water hyacinth intensifies intraspecific competition, which can cause a large number of water hyacinths to rot and die, resulting in eutrophication of water bodies, further promoting the growth of water hyacinth, forming a vicious circle. At the same time, the dense water hyacinth hinders sunlight from penetrating the water body and the flow of the water body, reducing the dissolved oxygen in the water body, and the growth of water hyacinth consumes a large amount of dissolved oxygen, which destroys ...

AI Technical Summary

Problems solved by technology

[0003] At present, water hyacinth treatment methods mainly include: manual salvage, professional salvage ship salvage, drug removal and introduction of natural enemies, etc., but these treatment methods are restricted by factors such as construction period, cost, working conditions, secondary hazards, etc., and each has its own limitations.

The efficiency of manual salvage is low, and water hyacinth has a strong reproductive ability, which is suitable for small-area water hyacinth salvage operations. For large-scale water hyacinth operations, manual salvage requires a large amount of manpower and high cost of auxiliary equipment at one time.

Professional salvage ships have fast salvage efficiency and good results, but the salvage price is high and have high requirements for operating space. Ensure that equipment is in and out of the field

Drug removal will affect water quality, cause secondary pollution, and aggravate water pollution

The introduction of natural enemies is based on the predation of organisms to remove water hyacinth, such as the introduction of water hyacinth weevil, but the effect is slow, and it usually takes 3-5 years to gradually appear.
