Traction device fixing structure of solar chasing system

The present invention relates to a traction device fixing structure of a solar solar chasing system; in particular, a collecting system that uses a flexible traction device to drive a photovoltaic module or a solar energy conversion mechanism, and is provided with an auxiliary fixing structure. Means.

It is a well-known skill to apply solar collector modules and power modules to collect solar thermal energy and convert it into electrical energy for use in live and industrial systems; for example, US 2010/0180883 A1 "Actuated feedforward controlled solar tracking" System, KR 10-1085172 "Sun Tracking Device" patent, etc., provide a typical embodiment.

Basically, the KR 10-1085172 case discloses a base column directly embedded in the ground and a horizontal tracking device and a light collecting plate disposed on the base column; the horizontal tracking device combines at least one hydraulic cylinder actuator; and, the oil pressure The cylinder actuator is pivotally connected to the light collecting plate. The horizontal tracking device and the hydraulic cylinder actuator drive the concentrating plate to move together with the encoder for detecting the rotation angle, the optical coupler for detecting the rotational azimuth reference address, and the main control portion.

The US 2010/0180883 A1 case discloses a base column and a light collecting plate disposed on the base column; a cross type base is arranged at the bottom of the base column; and a plurality of hydraulic cylinders are arranged between the light collecting plate and the cross type base Actuator. With the computer control platform that stores various parameters or data, the hydraulic cylinder actuator drives the concentrating plate to be different with the sun address. Tilt in direction or angle.

It can be understood that in order to stabilize the load or support the entire light collecting system, the cross-shaped base must have a large enough area or volume; in contrast, the weight becomes relatively heavy. As will be appreciated by those skilled in the art, this will increase the difficulty of transporting and assembling the entire solar collector system.

The prior art has also revealed a technical means for applying flexible cable traction to the light-collecting plate; for example, Taiwan No. 86221611 "Reversible Solar and Wind Power Generation Device", No. 94112215 "Supporting Device for Solar Battery Support Plate" Patent Cases, etc., provide a feasible embodiment. The solar concentrating system has one end of the flexible cable fixed on the light collecting plate, the other end bypassing the pulley, and then wound around a rotating wheel; the pulley is fixed on the ground and the base with a fixing device (for example, a screw pile structure) Or other equivalent surface positioning body, as a fulcrum of the flexible cable traction motion. The control part of the solar light collecting system drives the rotating wheel to cause the flexible cable to pull the light collecting plate to generate different directions or angular movements.

A topic related to the structural design and application of such a solar-powered sun-collecting or concentrating system is that when the flexible cable cooperates with the rotating wheel and the pulley is used as a fulcrum to pull the concentrating plate to move, the concentrating plate will have a reaction to the flexible cable. Force, transmitted to the pulley. The vertical component of the reaction force creates the effect of pulling the pulley off the ground; the horizontal component of the reaction force forces the pulley to load the force of the lateral displacement. Therefore, after the solar chasing system is used for a long time, the vertical component and the horizontal component of the reaction force gradually loosen the fixing mechanism established between the anchoring device and the positioning body, causing the traction device to slip during operation or The stationing device is pulled out, affecting the effect of the traction device driving the light collecting plate; this situation is not what we would expect.

Typically, these references show the use and structural design of solar solar tracking or collection systems and their associated components. If the redesign considers the solar chasing system or the flexible traction device and related component structure, and the above application scenarios, making it different from the conventional one, it will be able to change its usage pattern and increase its application range, and different. In the old law.

For example, under the condition of having a stable load or supporting the entire light collecting system, the base of the prior art must have a large enough area or volume, a large weight, is not conducive to transportation and assembly work, and the like, and a significant improvement is obtained; Further providing a fixing structure to resist and prevent an external force or reaction force pulling and fixing mechanism which may be generated between the flexible traction device and the light collecting plate during operation, causing the fixing mechanism to loosen, causing the traction device to slip or destroy the traction device to drive the light collecting plate during operation. The role of the situation. None of these topics have been specifically taught or disclosed in the above references.

Therefore, the main purpose of this creation is to provide a traction device fixing structure for the solar chasing system, which provides a strengthening and stabilizing effect to prevent the fixing mechanism from being loosened or pulled out.
