Crank shaft mandril type transmission system of solar photo-thermal giant bracket mirror field

Abstract

The invention discloses a crank shaft mandril type transmission system of a solar photo-thermal giant bracket mirror field, which comprises a main helical mandril mechanism, an auxiliary helical mandril mechanism and a crank and crank shaft transmission mechanism, wherein the main helical mandril mechanism comprises a main mandril, the auxiliary helical mandril mechanism comprises an auxiliary mandril, the crank and crank shaft transmission mechanism comprises a main crank, an auxiliary crank and a crank shaft, fixed ends of the main crank and the auxiliary crank are arranged on the crank shaft, the movable end of the main crank is movably connected with the movable end of the main mandril, the movable end of the auxiliary crank is movably connected with the movable end of the auxiliary mandril, the main crank and the auxiliary crank are arranged in a staggered along the rotation direction of the main crank and the auxiliary crank, and the main mandril and the auxiliary mandril push or pull corresponding main crank and auxiliary crank to rotate for completing output of torque. By adopting a pure mechanical transmission mode, the crank shaft mandril type transmission system has the characteristics of large speed reduction ratio, stable operation, capability of self locking, large output torque, and the like, and meets the transmission use requirement of a photo-thermal power generation sun-fixing tracking system.

Description

technical field [0001] The invention relates to a crankshaft ejector rod type transmission system of a giant bracket mirror field for solar thermal power generation. Background technique [0002] At present, domestic and foreign trough solar thermal power generation tracking drive systems mostly use hydraulic levers, hydraulic motors and other transmission methods. Using hydraulic transmission, the structure is complex, the volume is huge, and there are many auxiliary equipment. Due to the high-pressure state, the requirements for the material and connection method of the pipeline are very high. The phenomenon of leaking, leaking, leakage occurs from time to time, and the pressure on safety and fire prevention is very high. The high-pressure oil pump needs Regular maintenance and high failure rate, difficult maintenance, heavy maintenance workload, and large energy consumption. At present, there are also some purely mechanical drive methods, such as worm gear reducer drive,...

Problems solved by technology

Using hydraulic transmission, the structure is complex, the volume is huge, and there are many auxiliary equipment. Due to the high-pressure state, the requirements for the material and connection method of the pipeline are very high. The phenomenon of leaking, leaking, leakage occurs from time to time, and the pressure on safety and fire prevention is very high. The high-pressure oil pump needs Regular maintenance and high failure rate, difficult maintenance, heavy maintenance workload, and large energy consumption

At present, there are also some purely mechanical drive methods, such as worm gear reducer drive, which are not mainstream products at present, and there are not many market applications, and there are certain limitations in their use and application.
