Problems solved by technology

[0005] The heat collectors in the prior art often adopt a fixed structure, which can only ensure the collection of solar energy when the sun directly shines on the heat collector during the day. Once the sun cannot directly shine on the heat collector, the heat collector thermal efficiency will decrease

Abstract

The invention discloses an automatic tracking solar heat collector pedestal, and belongs to the energy collection field; the automatic tracking solar heat collector pedestal comprises a H-shape support and a pedestal; a sensitization assembly can monitor the sun mobile conditions, and sends the mobile conditions to a motor control module, thus respectively controlling a rotary motor and a lifting motor, arranged in the solar heat collector pedestal, to operate; therefore, the solar heat collector carried by the solar heat collector pedestal can be directly irradiated by the sun in a long time, thus prolonging sun light irradiation reception time, and improving heat collector thermal-arrest efficiency.

Description

technical field [0001] The invention relates to the field of energy collection, in particular to an automatic tracking solar heat collector base. Background technique [0002] Today, as fossil fuels are becoming increasingly depleted, solar energy, as a renewable energy source, has become an important part of human energy utilization. In recent years, solar thermal utilization has developed particularly rapidly. Heat collectors are the basic components of solar thermal utilization systems. It directly determines the collection of solar light and heat by the system, so it is of great significance to improve the heat collection efficiency of the heat collector. [0003] Flat-plate collectors and vacuum tube collectors are currently the most widely used forms of solar collectors. When the two types of collectors are placed, the deviation angle from the due south direction is required to be no more than 15°, and they are generally placed in a fixed position due to the south. Bo...
