Description

Self-balancing fixed adjustable bracket

Technical Field

The utility model relates to the field of photovoltaic power generation, in particular to self-balancing of an adjustable bracket.

Background

In solar energy utilization, photovoltaic power generation is all converted from solar radiation energy to electrical energy by a panel assembly. Whether fixed, adjustable or tracking, is determined by the corresponding stent configuration.

The fixed support has the advantages of good stability, simple structure, material saving, convenient installation and low cost, and is unnecessary to adjust in the life cycle. The tracking type photoelectric conversion device has the advantages that the photoelectric conversion efficiency is high in unit area, but the support structure is complex, the tracking and reciprocating motion is frequent, and the abrasion of a movable part is increased to influence the service life. The tracking movement is reinforced and the controller and the driving member are additionally arranged, so that the cost is greatly increased.

The adjustable support is arranged between the two, the support structure of the adjustable support eliminates the frequent tracking of azimuth angles moving along with the sun at any time, and the adjustable push rod is manually operated only by manpower to track the noon altitude of the sun for micro adjustment along with the seasonal variation. Only a few adjustments (which may be selected as accuracy is needed) are needed during the year. Thus the structure of the adjustable fixing bracket is greatly simplified. Therefore, the solar azimuth tracking device is simpler than a flat single-axis, oblique single-axis and double-axis tracking bracket structure for solar azimuth tracking; although the photoelectric conversion efficiency is relatively lowered, the efficiency is remarkably improved compared with that of the fixed bracket. Is an economical type of quasi-tracking.

The traditional adjustable bracket is characterized in that components are uniformly and symmetrically arranged on two sides of the main beam. Under the normal condition, the support barycenter skew greatly leads to the eccentricity great, and it is more laborious to adjust the support inclination through the push rod, and this design has optimized the support barycenter position with adjustable, adjusts the support upper portion structure installation relative position with adjustable, reduces the eccentricity of adjustable support, has effectively reduced the required power when the push rod promotes the subassembly upset.

Disclosure of Invention

The utility model aims at: aiming at the problems, the self-balancing adjustable bracket solves the problem of labor-consuming rotation of the push rod caused by larger eccentricity in the prior art.

The technical scheme adopted by the utility model is as follows:

the utility model provides a fixed adjustable support of self-balancing, fixed adjustable support of self-balancing mainly comprises panel subassembly, purlin, bracing, girder, stand, bearing housing, purlin up end in the fixed adjustable support of self-balancing is provided with the bolt through-hole, and the bolt through-hole passes through the bolt external member rigid coupling along purlin length direction center asymmetric arrangement, panel subassembly and purlin up end, and its mounted position is along purlin length direction toward one end skew.

In the structure, bolt through holes are formed in the lower end face of the purline in the self-balancing fixed adjustable support, the lower end face of the purline is connected with bolt holes on two sides of the diagonal brace through bolt assemblies, the bolt through holes are formed in the lower end face of the purline in the self-balancing fixed adjustable support, the lower end face of the purline is connected with the diagonal brace through bolt assemblies, and the purline and the diagonal brace form a whole.

In the structure, the purline and the inclined strut form a whole body which is uniformly arranged on the main beam, the main beam penetrates through the bearing sleeve in the self-balancing fixed adjustable bracket, the main beam is clamped by the high polymer bearing arranged in the bearing sleeve, the retaining rings are arranged on two sides of the bearing sleeve to prevent the high polymer bearing from sliding out of the bearing sleeve, and the bearing sleeve is arranged on the top end of the upright post in the self-balancing fixed adjustable bracket.

The utility model provides a fixed adjustable support of self-balancing formula, fixed adjustable support of self-balancing formula is superstructure mounted position skew, and support focus changes, and in support inclination adjustment process, the barycenter is near the rotation center all the time removed, and the eccentricity reduces for adjustable support becomes comparatively light when rotating the push rod.
