Specific embodiment
Illustrate the principle of the present invention first: being fixed when 2 both ends of flexible link belt are fixed on the position that photovoltaic is fixed on bracket,
When driving the position of flexible link belt driving device 3 fixed, with the fixed bracket of photovoltaic as solar tracking angle is adjusted,
The distance between two fixing points and driving device summation can change, and when longest is 1.414 times most in short-term, when making flexibility
When connecting band 2 is in tensioned state, the support bracket fastened angle of photovoltaic could be regulated and controled, while can also make the fixed bracket of photovoltaic
In steady status.
As shown in Figure 1 and Figure 2, with activity branch between a kind of single-axis solar tracking bracket, including column 11 and column 11
The photovoltaic that point is connected fixed bracket, flexible link belt 2, flexible link belt driving device 3, the photovoltaic support bracket fastened two
Side is fixed with the both ends of flexible link belt 2, and the inclination angle between the fixed bracket of photovoltaic and column 11 is controlled by flexible link belt drive
Dynamic device 3, it further includes length compensation device that the flexible link belt driving device 3 is fixed relative to 11 position of column, described
Length compensation device when being used for the change of pitch angle between the fixed bracket of photovoltaic and column 11, keep flexible link belt 2 to be in
The state of tension.So-called length compensation refers to compensation the distance between two fixing points and driving device summation, with inclining
The variation at angle, when the sum of linear distance between two fixing points and driving device is shorter, by changing flexible link belt 2
Stroke changes the technological means of total length.
The length compensation device includes compensation point device and compensation fulcrum bracket, and the compensation fulcrum bracket connects
It connects the fixed bracket of photovoltaic and compensation point device, the compensation point device is touched with flexible link belt 2.I.e. by using branch
Frame heads on or hauls always flexible link belt 2 at different inclination angles, to realize that flexible link belt 2 is in tensioned state.
The compensation fulcrum bracket includes the rigid rod 41 that two tail ends are fixed on the fixed bracket of photovoltaic, two rigidity
The front end of stick 41 is mutually fixed with compensation point device.A nearly triangle is integrally formed in two rigid rods 41 and the fixed bracket of photovoltaic
The rock-steady structure of shape, intensity are higher.
As shown in Fig. 2, the quantity of the compensation point device and 2 contact point of flexible link belt is at least two.When connecing
When the quantity of contact is one, it is also able to achieve the purpose of the present invention in most cases, but contact unique in the case
Point and two rigid rods 41 will form a triangle, as the contact point of triangular front end, be adjusted to pole in some angles
In the case where limit, it is easy to collide with flexible link belt driving device 3.It, can be by adjusting contact when contact point is greater than one
The position of point, makes it all not encounter flexible link belt driving device 3 at any inclination angle.
As shown in figure 4, being equipped with idler wheel 42 on the compensation point device and 2 contact point of flexible link belt, can reduce
With the friction of flexible link belt 2, extend life of product.
Further include the compressed spring for being mounted on 42 rear side of idler wheel, gives idler wheel 42 to 2 direction thrust of flexible link belt.When inclining
When angle is adjusted to some extreme angles or when length caused by the reasons such as 2 aging of flexible link belt changes, pass through compression
Idler wheel 42 to being pushed forward, can be corrected lesser error by spring.The mounting means of compressed spring is simple, since its is small in size, In
It is not identified in diagram, situation of the those skilled in the art according to scene, it can be on rear side of idler wheel 42 in a number of different manners
It is installed.
The flexible link belt 2 is chain or cable wire.Chain and cable wire are the most common flexible link belts 2, simultaneously
Itself also has higher intensity.
Equipped with spring is coordinated on the flexible link belt 2, flexible link belt 2 is allow to stretch.Inclination maneuver is to some
When extreme angles or when length caused by the reasons such as 2 aging of flexible link belt changes, it can be corrected by coordinating spring
Lesser error.
The flexible link belt driving device 3 includes the shaft 31 made flexible connection attachment thereon and shaft driving dress
It sets, flexible link belt 2 is driven when shaft driving device drive shaft rotates.When flexible link belt 2 carries out different type selectings, choosing
Flexible link belt driving device 3 is also required to change therewith, and when such as using chain, flexible link belt driving device 3 uses tooth
Disk can make chain that fluted disc be followed to rotate, these selection modes are all the ordinary skill in the art, repeat no more.
As shown in figs. 3 and 5, equipped with the transmission shaft for connecting each shaft 31 between adjacent single-axis solar tracking bracket
5, the shaft driving device is speed reducer 32, and speed reducer 32 drives multiple single-axis solars to track simultaneously by transmission shaft 5
The shaft 31 of bracket.Drive speed reducer 32 when, can by rotating the shaft 31 of multiple solar energy tracking brackets, thus
The multiple solar energy tracking brackets of one secondary control synchronize adjustment.
The transmission shaft 5 is fixed on the column 11 below the fixed bracket of photovoltaic.When transmission shaft 5 is fixed on column 11
When, enough intensity can be obtained, and position is more stable, the variation of the distance between two fixing points and driving device summation
Curve is easier to be calculated.
The variation of sun declination is followed, the support bracket fastened angle of photovoltaic is being adjusted, and the position of idler wheel 42 also can be with
The angle be changed, thus realize tighten flexible link belt 2 purpose.And length, angle and the rolling of rigid rod 41
The position of wheel 42 needs to adapt to different single-axis solar tracking brackets and is changed, and a combination thereof mode is according to two fixing points
The change curve of the distance between driving device summation guides to calculate and be arranged as data.
Present invention saves materials, reduce power consumption, while realizing using flexible link belt 2 and realizing to photovoltaic bracket
Angle adjustment in length issue and the problem of rated wind velocity.
