Clock type solar simple tracking apparatus

Abstract

This invention relates to a clock type solar energy simple tracking rotation device. It includes solar energy heat collecting board, moving support for assembling the solar energy heat collecting board, base, vertical shaft connecting to the base, rotating spigot shaft matching the vertical shaft and clock mechanism which undertakes solar energy hour angle tracking control. Transmissions are respectively arranged on the moved rotating arm and fixed base. They control electric engine to output torque through clock power source and controlling element. The torque drives moving support and solar energy heat collecting board to carry out solar energy hour angle reciprocating tracking rotation along the vertical shaft. It makes the moment of resistance and driving power dissipation lowest. This invention is lighter and smaller. It is adequate for portable and movable equipments.

Description

technical field [0001] The invention belongs to the field of solar energy applications, in particular to a clock-type simple tracking device for solar energy. Background technique [0002] A large number of existing solar applications require solar energy utilization systems in remote areas, mainly such as miniaturized and cheap solar photovoltaic power generation systems, etc., to solve the energy supply problem in remote areas. Among them, the use of tracking devices can improve the light absorption of solar devices The efficiency is as high as 37%, and according to the relationship between the incident angle of the sun and the light absorption efficiency, when the deviation of the incident angle of the sun is not more than ±5%, the loss of the light absorption efficiency is within 3%. Therefore, it should be as possible as possible A simple tracking device for solar energy is used to greatly improve the cost performance of solar energy installations. For this kind of sim...

AI Technical Summary

Problems solved by technology

This kind of device has many control links, the tracking operation passes through the sensor signal, the control circuit structure is complex, and the tracking transmission mechanism is bulky, which will inevitably result in a large rotational resistance torque under wind load. Increasing the power of the motor will increase the power consumption. Stepping motor control and worm gear one-way transmission can only carry out continuous stepping and turning motion, which makes the device cost and operating cost high, and the performance cost price ratio of the device is low. It is only suitable for scientific research and other occasions that need to accurately track sunlight. ; In addition, this device also has the reliability defects of poor wind resistance and large jitter; and the system is heavy and not easy to move or carry; tracking rotation in the longitude and latitude directions using worm gear precision transmission is not suitable for direct Long-term use and mass promotion and application in outdoor occasions
