Device for solving problems of lower salvage efficiency of duckweed in river channels and overhigh water content of duckweed

Abstract

The invention relates to the technical field of ecological restoration, and discloses a device for solving the problems of lower salvage efficiency of duckweed in river channels and overhigh water content of the duckweed. The device comprises a salvage net, duckweed and algae are automatically salvaged through the salvage net, a supporting rod is movably connected to the upper portion of the salvage net, the salvage net is supported and limited through the supporting rod, and the surface of the supporting rod is movably connected with a limiting plate. Through cooperative use of the supporting rod, the limiting plate, a special-shaped disc and a partition plate, water is automatically drained after the algae or duckweed in the river channels is salvaged, the draining efficiency is improved through vibration, more time and labor are saved, and the situation that the salvaged duckweed is difficult to collect due to the fact that the water content of the salvaged duckweed is too large is avoided; and through cooperative use of a first disc, a fixing rod, a second disc and a push rod, when the duckweed and algae are salvaged, the duckweed and algae can be salvaged automatically through vertical movement, manual salvage through a long rod is replaced, more time and labor are saved, and the working efficiency during salvage is improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a device for solving the problems of low duckweed fishing efficiency in rivers and excessive water content of duckweed. Background technique [0002] With the development of social production, rivers all over the world are facing different degrees of pollution from industry, agriculture, life, etc. Landscape water bodies such as lakes and rivers in cities are important components of urban human settlements, but due to their Easy to pollute, small water environment capacity, poor water self-purification ability, etc. When a large amount of industrial wastewater, domestic sewage, and plant nutrients in farmland runoff are discharged into slow-flowing water bodies such as lakes and rivers, aquatic organisms, especially algae, will multiply in large numbers , destroying the ecological balance. [0003] Therefore, in order to carry out ecological restoration, it is usu...

Problems solved by technology

[0002] With the development of social production, rivers all over the world are facing different degrees of pollution from industry, agriculture, life, etc. Landscape water bodies such as lakes and rivers in cities are important components of urban human settlements, but due to their Easy to pollute, small water environment capacity, poor water self-purification ability, etc. When a large amount of industrial wastewater, domestic sewage, and plant nutrients in farmland runoff are discharged into slow-flowing water bodies such as lakes and rivers, aquatic organisms, especially algae, will multiply in large numbers , destroying the ecological balance

[0003] Therefore, in order to carry out ecological restoration, it is usually necessary to salvage algae and duckweed by special personnel. However, the existing salvage devices are relatively simple. Usually, special personnel use long poles and other devices to stand on the bow of the ship to salvage. There may be a phenomenon of tilting of the hull, so there are a series of safety hazards such as capsizing

At the same time, after the algae or duckweed are salvaged, the water content is too high, and the water usually needs to be drained, but it will take a long time to drain, resulting in low overall work efficiency

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device that solves the problem of low duckweed fishing efficiency in rivers and excessive water content of duckweed. The time-consuming and labor-intensive problem ensures that the device can be automatically salvaged when operating, and the vibration is used to speed up the draining efficiency of water, which saves time and effort and improves the overall work efficiency
