Problems solved by technology

[0005] In the foreign journal "Solar Energy", the test device designed with the title "Performance enhancement of parabolic trough collectors by solar flux measurement in the focal region" consists of a bracket structure, a sliding mechanism and a semi-transparent Lambert property of the photoelectric sensor installed on the back. target, and installed on the outer surface of the collector for measurement, rather than the position of the focal axis, the final result obtained in this way has a large error, and the energy absorbed by the actual collector cannot be accurately evaluated, so it is impossible to evaluate the concentration. performance of optics

Abstract

A solar energy flow measurement instrument for a trough light condenser comprises a main body part, a supporting part and a transmission part, wherein the main body part consists of a lambert target, energy flow bases and two energy flow meters; the supporting part consists of a first end seat, an aviation plug, a drag chain fitting seat, five aluminum profiles, a cable drag chain and a second end seat; and the transmission part consists of two sliding rails, two sliders, a gear stand, a gear, a rack, a stepping motor, a coupler and a spool. The stepping motor (8) is connected with the gear (6) by the coupler (7), and the gear (6) is driven by the stepping motor (8) to do reciprocating movement on the rack (4). The slider (5), the coupler (7), the stepping motor (8), the gear stand (9), the cable drag chain (10), the spool (11) and the lambert target (12) which are combined as a whole do the reciprocating movement on the sliding rails (3) by the lambert target (12) and the cable drag chain (10) which are connected with the gear stand (9) through the driving of the gear (6).

Description

Technical field [0001] The invention relates to a trough type concentrator solar energy flow density measuring instrument. Background technique [0002] The measurement of the energy flow density distribution of the focused spot of the condenser plays a key role in optimizing the efficiency of the system. The optimization degree of the system depends on the position of the receiver in the condenser and the energy flow density distribution on the surface of the receiver, and these factors are through It is determined by modifying the tracking parameters and the curvature of the reflecting surface. Changing the position of the receiving surface of the optical axis of the concentrator and accurately measuring the distribution of energy flow density on the receiving surface can lay the foundation for the future development of the concentrator system. The receiver efficiency is calculated by the ratio of the output thermal energy on the receiver to the input radiant energy incident o...
