Aiming at the deicing work of high voltage transmission lines, the existing deicing robots for high voltage transmission lines are analyzed using TRIZ theory,and the technical contradictions that exist in the deicing robots that are unable to surmount obstacles or difficult to control and dangerous in the process of surmounting obstacles are summarized. Applying 39 engineering parameters to establish the corresponding contradiction matrix to find the appropriate invention principle,using the invention principle to carry out innovative design and establish the corresponding dwarf model for analysis, a new type of intelligent deicing robot with strong obstacle surmounting ability for high-voltage transmission lines is designed, which is used to solve the low efficiency, long time and high risk of artificial deicing method; The heating and ice melting method has high energy consumption and harsh service conditions. The three-dimensional modeling software Soildworks is used to model and assemble the deicing robot, and the finite element analysis method is used to verify the feasibility of the structure of the key components, which provides a feasible idea for the further design of the intelligent deicing robot for high-voltage transmission lines.
To improve the efficiency of the submersible pump, a small diameter 25mm pump was developed. At the same time, a laboratory test platform was established to test the performance of the pump and verify the rationality and feasibility of the submersible pump design. The influence of the sinking rate and the liquid level ratio on the submersible pump performance is mainly discussed. The pumping test platform provides test guarantee for the research of efficient pumping equipment, shortens the research cycle and has important influence on field production and efficiency improvement.
