A heliostat single-axis sun tracking device for solar power stations

Abstract

The invention discloses a heliostat single-axis tracking device for a solar power station, which comprises a support rod and a housing fixedly connected to the upper end of the support rod. One end outside the casing is fixedly connected with a heliostat, and a geared motor is installed on the inner wall of the casing. The invention drives the heliostat to rotate through the deceleration motor, so that the heliostat always faces the sun, so that the heliostat can receive more light; the rotating shaft drives the winding roller to rotate, the winding roller rotates, and the traction line drives the slider to move , the slider moves so that the air in the telescopic airbag enters the round cavity through the air guide cavity, and is ejected through the air nozzle. The high-speed airflow ejected through the air nozzle rotates the blade, and the impeller rotates through the connecting shaft to drive the bristles to set the sun. The surface of the heliostat is cleaned; the air in the cavity is discharged through the exhaust port, and the dust under the brush is blown away, which ensures the long-term cleaning of the heliostat.

Description

technical field [0001] The invention relates to the technical field of new energy applications, in particular to a heliostat single-axis solar tracking device for a solar power station. Background technique [0002] The problem of energy shortage and environmental pollution is becoming more and more serious, and the fundamental way to solve the problem is to develop new energy, especially renewable energy. In terms of large-scale power generation, tower solar thermal power generation will be the lowest cost of all solar power generation technologies. The heliostat is one of the key components of the tower-type solar thermal power station, and it is also the main investment part of the station, accounting for 52% of the total investment of the station. However, the utilization rate of the light energy of the existing heliostat is low. The sun is always moving, and the heliostat cannot always face the sun. At the same time, the dust on the heliostat will also reduce the light...

The heliostat is one of the key components of the tower-type solar thermal power station, and it is also the main investment part of the station, accounting for 52% of the total investment of the station. However, the utilization rate of the light energy of the existing heliostat is low. The sun is always moving, and the heliostat cannot always face the sun. At the same time, the dust on the heliostat will also reduce the light setting efficiency of the heliostat, and the daily cleaning cost of the heliostat is high. How to make the heliostat receive more It has always been a difficult problem in this field to obtain more light and improve the reflection efficiency of heliostats
