Solar focus-fixing receiving arrangement for synchronously adjusting curvature and elevation angle

Abstract

The invention discloses a solar energy focus receiving device which can synchronously regulate curvature and elevation angle. The solar energy focus receiving device comprises a frame and a condenser and is characterized in that a condenser surface curvature regulation positioning point and a regulating rod for regulating the condenser surface curvature and the elevation angle are arranged on thecondenser. A condensing focus is arranged on an extended line of a longitudinal center line of a perspective rotation axis of the condenser. The frame comprises a frame casing and a lifter which is arranged in the frame casing. The device also comprises a sun tracing mechanism which drives a gear to rotate by a screw-type promoting chain. The solar energy focus receiving device reduces the manufacturing cost, improves the practicality, solves the problem that the solar energy can not be transmitted to the internal of a room or another place to be used by means of transmission method in a longtime and widens the high temperature heat collecting industrial application field. The solar energy focus receiving device can be used as a middle and high temperature heat source of a family for heating up water, cooking and heating and can also be used for heating and power generating for hot water engineering. The solar energy focus receiving device can be conveniently used for regularly arrayed and industrialized energy collection.

Description

Solar fixed-focus receiver capable of adjusting curvature and elevation angle synchronously Technical field The invention relates to the technical field of solar energy utilization, in particular to a heat collection device that collects solar energy and is used for high-temperature heating, hot water engineering and power generation. Background technique Traditional solar energy collectors generally use a single parabolic condenser as the condenser, and track the sun through a control system to make the incident direction of sunlight parallel to the main optical axis of the mirror, and the focus of the condenser moves with the movement of the condenser. Since the receiver is at the focus, it will move synchronously with the movement of the focus. This will have four insurmountable shortcomings. First, the receiver should not be too large. The receiver blocks the effective area of ​​the condenser to receive sunlight and affects the collection efficiency. In order to reduce t...

Another example is the invention patent application of 200610048636.9. Although the design of the fixed focus of the condenser is adopted, the entire condenser has to revolve around the focus, which requires a strong drive capability, complex structure, large energy consumption, large footprint, and wind resistance. Poor ability, it is difficult to enter the stage of actual development and application
