Conical rotor and pipeline electric generator

Abstract

The invention relates to the technical field of motors and provides a conical rotor and a pipeline electric generator. The conical rotor comprises a rotor body. The rotor body comprises a constant diameter section and a conical section. The constant diameter section comprises a first end and a second end opposite to the first end. The conical section comprises a third end and a fourth end. The third end is connected with the second end. The diameter of the conical section is gradually reduced from the third end to the fourth end. At least two flow guiding grooves are formed in the outer wall of the conical section. Each flow guiding groove is sunken inwards from the outer wall of the conical section and provided with a bottom surface and a stress surface connected with the bottom surface, the stress surface and the axial lead of the rotor body intersect, and the included angle of the stress surface and the axial lead of the rotor body is an acute angle or an obtuse angle. Through the conical rotor, the operation cost can be greatly reduced. The pipeline electric generator comprises the conical rotor and a pipeline body arranged on the conical rotor in a sleeving mode. The pipeline body is provided with a feeding inlet arranged at the fourth end in a sleeving mode, and the fourth end and the feeding inlet are the same in shape. The pipeline electric generator is suitable for micro voltage and low fluid electric generation.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a conical rotor and a pipeline generator. Background technique [0002] Because of its heavy weight, the solid rotor needs to provide a large driving force to realize its rotation and power generation.

Problems solved by technology

[0002] Because of its heavy weight, the solid rotor needs to provide a large driving force to realize its rotation and power generation. In this way, it needs to consume a lot of original energy, and it can only work under a certain starting energy. In the state of micro flow and small flow It cannot be started under the environment, so the scope of application is limited, and its cost is high, cost consumption is large, and the efficiency of power generation is low. The operating cost and efficiency including transportation, installation, maintenance, etc. will be seriously affected. Compared with solid rotors, The weight of the hollow rotor is reduced, avoiding the above problems

[0003] However, although compared with the solid rotor, the weight of the usual hollow rotor is reduced, which improves the situation that requires a large driving force to realize its rotation and power generation. However, under the condition of small flow, the fluid flows through the gap of the hollow rotor. If the flow that is not enough to push the rotor is reached, the rotor cannot run, so the purpose of power generation cannot be achieved, and its cost and cost consumption are still not low, and the operating cost and efficiency are still high, especially in the case of micro-flow and initial flow. power generation under conditions
