Cylindrical Cable Net Reflection System Driven by Single Telescopic Rod Turntable

Abstract

The invention discloses an annular cylinder type cable net reflecting system driven by a single telescopic rod turntable. The annular cylinder type cable net reflecting system comprises an outer ring (1), a central supporting column (3), a net surface cable (9), a traction cable (10), a linear telescoping device (4), a fixed supporting rod (5), a lower rotating platform (6), a supporting bracket (7) and an upper platform (13). The central supporting column is fixed at the center of the outer ring (1) by means of a supporting cable (12). The top of the central supporting column is provided with a feed source (2). A fastening cable (8) is arranged between the net surface cable and the traction cable. Deformation of the net surface cable can be controlled through adjusting the length of the fastening cable, thereby changing shape of the reflecting surface. The length of the linear telescoping device (4) is adjusted so that the upper platform tracks pitch angle change. An azimuth angle is tracked through rotation of the lower rotating platform (6), thereby satisfying a requirement for a gesture which is required by the system. The annular cylinder type cable net reflecting system has advantages of simple structure, small weight and high flexibility. Accurate control for azimuth and pitch of the reflection system can be realized. The annular cylinder type cable net reflecting system can be used for reflection or converging of light energy or electric energy.

Description

technical field [0001] The invention belongs to the technical field of electromechanical drive, and in particular relates to a ring-column type cable-net reflective system that realizes azimuth and pitch control through the drive of a single telescopic rod turntable, which can be used for the reflection or convergence of electromagnetic energy or light energy. Background technique [0002] At present, large-scale reflection systems are not only widely used in the field of electronic information technology, but also gradually expanded and applied to the field of solar energy application technology, which can provide a strong technical guarantee for the application of next-generation clean energy. Existing large-scale reflective systems usually include reflectors and tracking and positioning mechanisms.

Since the gravity of the space environment is close to zero, this soft structure of rigid-flexible combination can form the desired surface accuracy, and the weight is ultra-light. Usually, its caliber surface density does not exceed 0.4Kg / m 2 , the construction cost and material cost of this structure are very low, but this cable net structure cannot be used directly on the ground, because the surface accuracy of the reflective surface will be greatly reduced after being affected by external loads such as gravity and wind on the ground , cannot meet the requirement of using

[0006] On the pitch and azimuth angle adjustment control device, that is, the tracker, the traditional two-axis series tracker is common at present, which controls the azimuth and pitch angles through two axes, and realizes tracking and positioning through the change of angles in turn. This kind of tracker has a complex structure, poor flexibility and stability, high processing and maintenance costs, low installation efficiency, and the cumulative errors generated at the same time are difficult to eliminate
