Abstract

A horizontal solar tracker is provided for solar tracker and solar moduli. The horizontal solar tracker uses a truss device to enhance bending moment endurance. The truss device has good stress strength. Thus the present invention can resist deformation.

Description

FIELD OF THE INVENTION

The present invention relates to solar tracker; more particularly, relates to setting solar trackers/solar moduli on a horizontal solar tracker apparatus with structure strengthened by a support body of staggered rectangular beams to prevent from deformation.

DESCRIPTION OF THE RELATED ART

In FIG. 8 a prior art mainly has a stud 90 set in a foundation 92. The stud 90 is a hollow thick wall tube. Solar moduli are combined with a tube 91 under a solar tracker to be set on the stud 90 for generating power. Although the prior art carries solar trackers/solar moduli 93 the stud 90 simply has a stud bracing design. Under shear effect of strong wind, the stud 90 does not have resistance to keep angle of inlet light for obtain enough solar density shown on the solar trackers/solar moduli 93 and thus the prior art does not generate power effectively. In a word under strong wind, bending moment of the stud 90 may be deformed and power is not generated effectively. Hence, the prior art does not fulfill all users' requests on actual use.

The main purpose of the present invention is to set solar trackers/solar moduli on a horizontal solar tracker apparatus with structure strengthened by a support body to prevent from deformation.
Another purpose of the present invention is to obtain effective stress resistance and bending moment endurance under shear effect of strong wind by using a truss device of staggered rectangular beams to enhance stress strength.
To achieve the above purposes, the present invention is a horizontal solar tracker apparatus, comprising a support body, a combining part, a solar modulus crutch a trig forks elevator and an azimuth (AZ) bearing device, where the support body comprises a support stud and a support part; the support body processes motion and improves structural strength; the combining part combines the support body; the solar modulus crutch has solar trackers/solar moduli on the solar modulus crutch; the trig forks elevator together with the solar modulus crutch is placed on the support body; the trig forks elevator processes a motion having an elevation angle to the solar modulus crutch; the AZ bearing device is located between the combining part and the support body; and the AZ bearing device drives the support body to process a rotation having an AZ angle to the solar modulus crutch. Accordingly, a novel horizontal solar tracker apparatus is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.
Please refer to FIG. 1 which is a perspective view showing a structure of a preferred embodiment according to the present invention. As shown in the figure, the present invention is a horizontal solar tracker apparatus, comprising a support body 1, a combining part 2, a solar modulus crutch 3, a trig forks elevator 4 and an azimuth (AZ) bearing device 5, where a truss device of staggered rectangular beams is used to enhance durability of flexural strength.
The support body 1 comprises a support stud 11 and a support part 12, where the support stud 11 is combined with a plurality of prop stands 111 for positioning; and the support part 12 is a truss device of staggered rectangular beams 121 to enhance structural strength.
The combining part 2 is combined with the support body 1 where the combining part 2 is penetrated by the support stud 11 of the support body 1 or is fixed upon the support part 12 of the support body 1 for fixing and combining the support part 12 and the support stud 11.
The solar modulus crutch 3 is fixed on the support body 1 to set solar trackers/solar moduli 6 on the solar modulus crutch 3.
The trig forks elevator 4 together with the solar modulus crutch 3 is fixed on the support body 1 to process a motion having an elevation angle to the solar modulus crutch 3.
The AZ bearing device 5 is located between the combining part 2 and the support body 1 for driving the support body 1 to process a rotation having an AZ angle to the solar modulus crutch 3. Thus, a novel horizontal solar tracker apparatus is obtained.
On using the present invention solar trackers/solar moduli 6 are set on the horizontal solar tracker apparatus. The trig forks elevator 4 moves on the support body 1. The AZ bearing device 5 rotates between the combining part 2 and the support body 1. The support part 12 is a truss device to enhance durability of flexural strength and to be raised on the support stud 11 even when solar trackers/solar moduli 6 are increased in number. Besides, by using the truss device of staggered rectangular beams 121 to enhance stress strength, effective stress resistance and bending moment endurance are obtained under shear effect of strong wind. Thus the horizontal solar tracker apparatus has a strong structure with enhanced resistance and is prevented from deformation.
Please refer to FIG. 2 to FIG. 4, which are a perspective view, a top view and a side view showing a support body. As shown in the figures, a support part 12 of a support body 1 is a truss device made of staggered rectangular beams 121, where the support part 12 has a T shape at a top-down view and a step shape at a side view.
Please further refer to FIG. 5 to FIG. 7 which are a perspective view and a side view showing a trig forks elevator; and a side view showing joints of the trig forks elevator. As shown in the figures, a trig forks elevator 4 is a parallel amplifying device having a trig forks part to fix the support body 1 and a solar modulus crutch with casters at caster locations 7.
In FIG. 7, the trig forks elevator 4 comprises the trig forks part and a hydraulic cylinder 8 and the trig forks part comprises at nearest a first linkage 41, a second linkage 42, a third linkage 43 and a fourth linkage 44, where the trig forks part is linked to the support part 12 at a first joint J1 connecting the hydraulic cylinder 8 and further the support part 12 and a second joint J2 connecting the first linkage 41 and the support part 12; and the second joint J2 is horizontally located higher than the first joint J1.
