Description

Technical Field

[0001] The invention belongs to the technical field of water treatment auxiliary machinery, and in particular relates to a mechanical arm pipeline system for a device for removing algae grown on a channel slope. Background Art

[0002] Most inter-basin water transfer projects are connected through artificial channels, but the ecosystem of newly built artificial channels is simpler than that of natural rivers and lakes, and it takes a certain amount of time to reach a balanced and stable state. In the water bodies of artificially constructed water transfer projects, abnormal proliferation of algae occurs from time to time, which may affect the safety of water supply and water quality to a certain extent. Therefore, cleaning the algae attached to the channel slopes and eliminating the risks and hidden dangers that may be caused by the proliferation of algae are technical problems that need to be solved urgently, which have important ecological and environmental significance.

[0003] In order to avoid secondary pollution of water quality, at present, the removal technology of algae on the hard channel slopes at home and abroad often adopts physical removal methods, mainly including manual cleaning, mechanical friction cleaning and other methods. Manual cleaning is not only labor-intensive and inefficient, but also causes a large amount of algae flocs to enter the water, causing secondary impacts, and cannot completely remove the algae buried in deep water and located in the visual blind spot. The mechanical friction cleaning method is widely used and has obvious effects. It can directly remove part of the algae attached to the channel slope. However, the mechanical arm of the existing mechanical removal device is in the form of a traditional mechanical arm plus a hose, which has the disadvantages of complex equipment structure, low operating efficiency, and difficult transportation of the removed algae. Therefore, there is a need for a mechanical arm pipeline system for the removal device of algae on the channel slope, which has a simple structure, is easy to operate, is conducive to improving the removal efficiency, and is convenient for transporting the removed algae.
