Multi-freedom degree base for large-scale sewage purifying robot

Abstract

The invention relates to a multi-freedom degree base for a large-scale sewage purifying robot. The multi-freedom degree base comprises a land walking device, two water surface walking devices, a lifting device and a delta parallel connection mechanism, wherein the two water surface walking devices are separately positioned on the left side and the right side of the land walking device, and are connected with the land walking device; the lifting device is positioned directly over the land walking device, and the lower end of the lifting device is connected with the upper end of the land walking device; and the delta parallel connection mechanism is positioned directly over the lifting device, and the lower end of the delta parallel connection mechanism is connected with the lifting device. The multi-freedom degree base disclosed by the invention has the functions of walking on the land, walking on the water surface and adjusting directional angles; the walking is quick and convenient, and the directional angles are convenient and flexible to adjust; and the problem that a base of a conventional sewage purifying robot is low in movement flexibility, narrow in adaptation range and low in stability is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-degree-of-freedom base for a large-area sewage purification robot. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemical substances, the acid, alkali, oxidant, copper, cadmium, mercury, arsenic and other compounds contained in polluted water and sewage, as well as benzene, dichloroethane, ethylene dichloride, etc. Alcohol and other organic poisons will kill aquatic organisms and affect drinking water sources and scenic spots; when organic matter in sewage is decomposed by microorganisms, it will consume oxygen in water and affect the life of aquatic organisms. After the dissolved oxygen in water is exhausted, organic matter will be anaerobic. Decomposition produces unpleasant gases such as hydrogen sulfide and mercaptan, further deteriorating water quality. China is a country with shortage of ...

Problems solved by technology

[0003] At present, there are physical methods, chemical methods and biological methods for sewage treatment. The chemical method of sewage treatment is to put chemical drugs into the sewage, and use chemical reactions or physical and chemical effects to purify sewage. At present, for reservoirs, lakes, rivers, ponds and other places The current chemical method of purifying sewage is to manually inject chemical drugs into the sewage by boat, which not only takes up a lot of labor, but also has low efficiency and certain dangers.
