Description
Technical field
The present invention relates to a kind of photovoltaic ball bearing tumbler suitable for flat uniaxial tracking bracket, belong to flat single shaft with
Track field of stents.
Background technology
With greatly developing for photovoltaic industry, solar bracket is also constantly changing, flat list currently used in the market
Axle tracking mount approach species is more, but few products suitable for mountain region project, it is adaptable to which the product of level land project is needed
Make and definitely change and could be installed on mountain region, still, all more or less there are problems that for these schemes.
For a mountain region photovoltaic project, the size of the mountain region gradient is often complex, is not certain single slope
Degree, existing flat uniaxial tracking bracket needs to be designed one by one according to the different gradient in mountain region to meet the installation need at scene
Ask, design efforts would and on-site installation work amount are very big.
The rotary centerline that support girder is for example tracked in segmentation scheme is the axis of girder, and rotary centerline is from system weight
Heart linear distance is larger, and the eccentric throw produced during rotation by gravity is larger, i.e., the additional moment produced by gravity is larger, rubs simultaneously
The additional moment that power is produced is also larger, it is therefore desirable to which larger external motivating force can just meet the job requirement of system.In order to gram
The problem of taking such, the reduction girder eccentricity of rotation of appearance of the prior art from flat uniaxial tracking bracket scheme obtain
Use, but the rotation connection structure of currently existing scheme middle girder structure uses bearing pin scheme, it is the face of cylinder to rotate contact surface,
The center line of cylinder is the rotary centerline of main beam structure, once after rotation connection structure fixation, tracks support main beam structure
Rotary centerline will also be defined, if infield for a variety of gradients mountain region when, need according to terrain slope
Size is designed corresponding rotation connection structure one by one, and workload is big to be difficult to imagine；In addition, the program is acclive
When table is installed, the hardness of weight component of the whole system along girder direction all at the top of a certain or a few root posts is even
Connect and overcome, all weight components compare concentration, the lateral force of column is unfavorable, chronically being rotated under hard contact to lead
Cause structural fatigue or serious abrasion occur.
The content of the invention
, can it is an object of the invention to provide a kind of photovoltaic ball bearing tumbler suitable for flat uniaxial tracking bracket
Effectively solve existing flat uniaxial tracking bracket tumbler in the mountain region of a variety of gradients with when the technical problem that exists, the dress
Put simple in construction, with Self-aligning and Self-balancing, the angle of tracking support girder will be automatically parallel with surface slope, install
It is very convenient.
The technical solution adopted in the present invention includes oscillating bearing, bulb pivot pin 6, flange；The oscillating bearing includes handle
Shoulder 2, inner ring bulb 4, outer race shaft bearing sleeve 3；The outer race shaft bearing sleeve 3 is fixed in handle shoulder 2；The inner ring bulb 4 is embedded in outside
Enclose in bearing holder (housing, cover) 3；The bulb pivot pin 6 is passed through inside inner ring bulb 4；Flange 5 is provided with the bulb pivot pin 6；The ball
Head pivot pin 6 line centered on x-axis in angle [alpha] makees 360 ° of tilt rotations, and angle [alpha] is 60 °~120 °.
The flange is provided with 3, wherein 2 two ends for being separately positioned on bulb pivot pin 6, another 1 is arranged on the upper of handle shoulder 2
Side.

The anchor ear 8 is provided with 2.
2 anchor ears 8 have been bolted girder 9, make the stress balance of photovoltaic ball bearing.
The oscillating bearing can also can make the part that spherical pivot pin is rotated with differing tilt angles for other.
The oscillating bearing is knee bulb joint bearing or straight-bar bulb joint bearing.
The oscillating bearing is the oscillating bearing of other sphere-contact forms.
The flange of the top of handle shoulder 2 is connected with arm 10 in embodiments of the present invention；The arm 10 passes through supporting plate 11
It is connected with column 12.
In embodiments of the present invention, there are a motor and rotary reducer, the motor driving revolution on the column 12
Reductor, rotary reducer is connected with motor, so as to reach the purpose of driving girder.
The present invention also provides a kind of application of photovoltaic ball bearing tumbler on flat uniaxial tracking bracket；When flat single shaft
When the gradient for tracking the infield of support is the mountain region of x degree, controlled during foundation construction the line angle of basic end face center with
The mountain region gradient is consistent, and control capital is wired to x degree after column installation, and arm at the top of girder and column is attached
Afterwards, the flange on handle shoulder is installed on arm one by one, the mounting distance of control handle shoulder is consistent during connection；So far, flat single shaft with
The angle of inclination of track support girder is then automatically adjusted as x degree by oscillating bearing, the α angles of oscillating bearing will automatically adjust for
X degree；There are a motor and rotary reducer on column, rotary reducer is connected with motor, motor driving rotary reducer, from
And girder is driven, girder is rotated in the presence of motor around sun altitude, and the angular range of rotation is ± 60 °.
A kind of photovoltaic ball bearing tumbler that the present invention is provided can also be applied on oblique single shaft.
The installation site by adjusting photovoltaic ball bearing reaches tracking mounting system center of gravity line and the spherical axle of photovoltaic
Center line coincidence is held, makes the required driving force reduction of tracking mounting system.
The beneficial effects of the invention are as follows：
(1) using photovoltaic ball bearing as the rotation connection structure of flat uniaxial tracking bracket girder can make flat single shaft with
A standard universal type product of product formation of track support, significantly reduces design efforts would.The universal product can be on different slopes
Installed on the mountain region of degree, and rotation connection structure has Self-aligning and Self-balancing, installs tracking support girder
Angle will be automatically parallel with surface slope, and it is very convenient to install.
(2) way of contact due to photovoltaic ball bearing in the range of random working angle is sphere-contact, therefore light
Volt ball bearing can bear the axle power on random working angle direction, and the axle power is entered between the contact sphere by both
Photovoltaic ball bearing and girder, are attached by row transmission by attachment structure, so as to by flat uniaxial tracking bracket system
The component of gravity is transferred uniformly into each root post, and whole system stress is more reasonable.
(3) because the photovoltaic ball bearing rotation friction is small, the arm of force of friction moment is also very short, is produced by frictional force
Additional moment can be ignored.And the center of rotation of tracking support girder is the position of center line of photovoltaic ball bearing, Ke Yitong
The installation site for overregulating photovoltaic ball bearing reaches that the center of gravity line of tracking mounting system is overlapped with photovoltaic ball bearing center line,
Reach " zero is eccentric " state；So driving force required during system work is with regard to very little, the motor of tracking support needs and revolution
The specification of reductor is relatively small, and cost has obtained significantly reducing.
