Problems solved by technology

[0003] In the existing lakes, garbage pollution is serious, and there are a lot of garbage such as aquatic plants and plastic bags in the water. When the propeller is in use, the rotating rod is easy to be entangled with garbage. After a long period of accumulation, it will affect the rotation of the propeller and it is difficult to clean it. , we propose an emergency protection device for underwater power mechanism

Abstract

The underwater power mechanism emergency protection device comprises a propeller body, a rotating rod is rotationally connected to the bottom of the propeller body, and fan blades are fixedly connected to the end of the rotating rod; the cleaning and scraping assembly is used for cutting garbage wound on the rotating rod, and the rotating rod is sleeved with the cleaning and scraping assembly; the push-out assemblies used for pushing the scraped garbage away from the rotating rod are arranged on the two sides of the scraping assembly, the garbage wound around the outer surface of the rotating rod is cut through a sleeve doing reciprocating motion back and forth, the garbage is crushed into multiple blocks, winding of the garbage to the rotating rod is relieved, and the garbage can be scraped away from the rotating rod. And the rotating movable plate drives the movable strip to enable the cut garbage to be away from the rotating rod, the crushed garbage is flushed out under the action of water flow, the device is good in cleaning effect, and the situation that garbage is stacked and wound on the rotating rod, and rotation of the propeller is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of underwater propellers, in particular to an emergency protection device for underwater power mechanisms. Background technique [0002] The most used equipment in lakes and rivers is the underwater electric propeller for ships. When the propeller is running, the impeller rotates to propel the liquid forward, and at the same time accelerates the disturbance between the layers of the water body to make it mix quickly to improve the hydrodynamic conditions. , its working principle is that the motor drives the impeller to rotate through the direct-coupled reduction device, the rotating impeller makes the liquid produce a swirling jet, and the shear force along the jet surface makes the liquid mix, so that the liquid outside the flow field undergoes friction. The mixing of water bodies is called, and at the same time, with the formation of volume flow, the controlled fluid is continuously pushed forward. [000...
