Azimuth transmission device of heliostat

Abstract

The invention discloses an azimuth transmission device of a heliostat. The azimuth transmission device of the heliostat comprises a main box, a worm gear mechanism, a drive motor, an inner gear ring, a planet carrier, a planet gear assembly and an output flange, wherein the worm gear mechanism is arranged inside the main box, an worm gear assembly of the worm gear mechanism is coaxially connected with an output-stage sun gear shaft; the drive motor is connected with the worm shaft of the worm gear mechanism through a speed reduction device; the inner gear ring is arranged inside the main box; the planet carrier is rotatably arranged on the main box and provided with a planet gear shaft, the planet gear assembly is rotataby arranged on the planet gear shaft and is respectively engaged with the inner gear ring and the sun gear on the output-stage sun gear shaft; and the output flange is connected with the planet carrier. The azimuth transmission device of the heliostat avoids the problems of large size, large stress, large abrasion during long-time operation, influence on the positioning accuracy due to the fact that a worm gear pair serves as the output stage.

Description

technical field [0001] The invention relates to the technical field of solar tower power generation systems, and more specifically, to a heliostat azimuth transmission device. Background technique [0002] The application of solar tower power generation is a tower system, which is also called a centralized system. It is equipped with many large solar reflectors on a large area, usually called heliostats, each equipped with a tracking mechanism to accurately reflect sunlight to a receiver on the top of a high tower. The light-gathering magnification on the receiver can exceed 1000 times. Here, the absorbed solar light energy is converted into heat energy, and then the heat energy is transferred to the fluid working fluid in the receiver pipeline. The type of working fluid can be: water, heat transfer oil, molten salt, air, etc. [0003] The working fluid takes water as an example. When the water is heated to several hundred degrees, it is sent to a high-temperature storage ...

AI Technical Summary

Problems solved by technology

At present, the main solution at home and abroad is "multi-stage planetary reduction component + worm gear pair + worm gear anti-backlash mechanism". , affecting the positioning accuracy

[0006] In addition, the complex structure of the worm gear anti-backlash mechanism reduces the efficiency of the system, and the simple structure of the spring-type worm gear anti-backlash mechanism will cause fatigue failure after repeated use and poor durability

[0007] Therefore, how to avoid the problems that the worm gear and worm pair as the output stage bring about larger volume, greater force, greater wear and tear during long-term operation, and affect positioning accuracy has become a technical problem to be solved urgently by those skilled in the art.
