Referring to fig. 3, the first party may be a telescoping base 32. I.e. telescopic base 32 is hinged to upright 1, and in particular telescopic base 31 is hinged to upright 1 at bottom 311 (shown in fig. 4) opposite to telescopic rod 33, in particular free end 331.

As mentioned above, the first bearing assembly 10a, i.e. the upright 1 and the cross beam 2, are connected by the manual push rod 3 to form the bearing assembly 10 of the triangular support, and the second bearing assembly 10b is the bearing assembly 10 of the upright 1 and the cross beam 2, which are connected by the adjusting stay rod 4 to form the triangular support.

The manual inclination angle adjustable support 100 can realize the inclination angle adjustment of the manual inclination angle adjustable support 100 by using the linear driving mode of the manual push rod 3 without a complex driving device, and simultaneously, the manual inclination angle adjustable support 100 is combined with the adjusting support rod 4 for use, so that the whole manual inclination angle adjustable support 100 has better wind resistance. In non-adjustment time, the adjusting support rod 4, the cross beam 2 and the upright post 1 can be in rigid triangular connection, so that the structural stability of the bracket under the working condition of strong wind can be realized, the impact of the strong wind on the manual push rod is reduced, and the stability and the service life of the push rod can be effectively improved.

In the illustrated embodiment, of the plurality of support assemblies 10, there are at least two first support assemblies 10a. Of the at least two first bearing assemblies 10a, the manual push rods 3 corresponding to the adjacent two first bearing assemblies 10a may be connected to each other by the driving lever 5.

The linear driving mode of the manual push rod 3 is matched with the transmission rod 5 to realize the synchronous motion of the manual push rod 3, and the single-person inclination angle adjustment of the bracket can be realized without a complex driving device.

In one embodiment, both ends of the transmission rod 5 may be respectively connected to the driving members 32 of the corresponding manual push rods 3. The transmission rod 5 can be a square tube, for example, and is sleeved outside a square shaft as the driving part 32, and in the same group of brackets, the manual push rod 3 is connected through the transmission rod 5, so that synchronous adjustment can be realized.

It is understood that the use of particular words herein to describe embodiments of the invention, such as "one embodiment," "another embodiment," and/or "some embodiments" means that a particular feature, structure, or characteristic described in connection with at least one embodiment of the invention is included. Therefore, it is emphasized and should be appreciated that two or more references to "one embodiment" or "another embodiment" in various places throughout this specification are not necessarily to the same embodiment. Furthermore, certain features, structures, or characteristics may be combined as appropriate in one or more embodiments of the invention.

In the illustrated embodiment, of the plurality of support assemblies 10, two support assemblies 10 located outermost in the east-west direction are each the second support assembly 10b.

A second support assembly 10b may be disposed between adjacent two of the first support assemblies 10a. This applies when the total number of the support assemblies 10 is odd and not less than five. For example, when there are five columns, a manual push rod 3 can be installed at the second and fourth columns, an adjusting brace 4 is installed in each of the other columns, and the manual push rods 3 of the second and fourth columns are connected by a transmission rod 5, so as to realize synchronous rotation adjustment. When the total number of the support assemblies 10 is even and not less than four, the two support assemblies 10 positioned at the middlemost in the east-west direction may be both the first support assemblies 10a. For example, in the illustrated embodiment, the total number of the supporting assemblies 10 is four, the manual push rods 3 are installed between the middle two upright posts 1 and the cross beam 2, the adjusting support rods 4 are installed between the upright posts 1 and the cross beam 2 at the two ends, and the transmission rod 5 is installed between the middle two manual push rods 3, so that synchronous transmission adjustment is facilitated. For another example, when three columns are used in each row, a manual push rod 3 can be installed at the middle column, and the adjusting stay bars 4 can be installed at the two side columns.

Further, of the plurality of support assemblies 10, only two support assemblies 10 located outermost in the east-west direction may be the second support assembly 10b. That is, in the plurality of bearing assemblies 10, the columns 1 and the beams 2 of other bearing assemblies 10 are not triangularly supported by the adjusting brace 4, for example, the first bearing assembly 10a of other bearing assemblies 10.

Referring to fig. 7, the adjusting stay 4 may be provided with an elongated slot 40 extending in the rod length direction L4. The plurality of hole sites A1 may be formed at a plurality of different locations along the rod length direction L4 of the elongate slot 40.

Referring to fig. 6, the fastener 6 may include a fastening bolt 61 and a fastening nut 62. The fastening bolt 61 can be threaded through the column 1 and the elongated slot 40 to the fastening nut 62.

The fastening nut 62 can be screwed or unscrewed with respect to the fastening bolt 61, whereby switching of the adjusting stay 4 between the aforementioned locked state and the aforementioned active state is achieved. That is, the tightening nut 62 is tightened with respect to the tightening bolt 61, so that the adjustment stay 4 can be in a locked state, and the tightening nut 62 is loosened with respect to the tightening bolt 61, so that the adjustment stay 4 can be in an active state.

Referring to fig. 7, the elongated slot 40 may have a plurality of wide slot segments 401 distributed along the rod length direction L4 and respectively constituting the aforementioned plurality of hole sites A1. Two adjacent wide slot segments 401 may be connected by a narrow slot segment 402. The slot width of the narrow slot segment 402 may be smaller than the slot width of the wide slot segment 401.

The fastening bolt 61 can be passed through the column 1 into one of the wide groove sections 401 of the adjusting stay 4. The fastening nut 62 may have a cylindrical section 621 and a flange section 622. The cylindrical section 621 has a free end 6211 and a connected end 6212.

The flange segment 622 may connect the connecting end 6212 of the cylindrical segment 621 and project laterally relative to the cylindrical segment 621. That is, the flange section 34 has a larger lateral dimension than the cylinder section 32. In the illustration, the flange section 34 is also a cylinder having an outer diameter greater than the outer diameter of the cylinder section 32.

In the aforementioned locked state, the free end 6211 of the cylindrical section 621 of the fastening nut 62 can penetrate the aforementioned one wide groove section 401 to be screwed with the fastening bolt 61. The narrow groove section 402 can stop the cylindrical section 621 so that the cylindrical section 621 is held in the aforementioned one of the wide groove sections 401, and the flange section 622 abuts against the adjustment stay 4. That is, the flange section 622 restricts the movement of the fastening nut 62 in the groove depth direction of the elongated groove 40, and the narrow groove section 402 restricts the movement of the fastening nut 62 in the groove length direction of the elongated groove 40 by restricting the cylindrical section 621, and therefore, the fastening nut 62 together with the fastening bolt 61 allows the entire fastener 6 to be locked in this wide groove section 401.

In the aforementioned active state, the cylindrical section 621 of the fastening nut 62 is disengaged from the aforementioned one wide groove section 401 in the groove depth direction of the elongated groove 40. The narrow groove section 402 allows the fastening bolt 61 to pass through in the rod length direction L4 to switch between the adjacent two wide groove sections 401.

That is, the slot section 402 is sized to allow the fastening bolt 61 to pass therethrough in the rod length direction L4 without allowing the cylindrical section 621 of the fastening nut 62 to pass therethrough. In other words, the narrow groove section 402 has a groove width between the cylindrical section 621 of the fastening nut 62 having a larger diameter and the fastening bolt 61 having a smaller diameter.

Wide slot segment 401 and narrow slot segment 402 are two segments of relatively wide and narrow slot widths, respectively, and do not limit the specific length of each slot segment, e.g., narrow slot segment 402 may be a point along the slot length direction of elongate slot 40, i.e., the rod length direction L4. Nor is the groove width required to be the same throughout each groove segment. For example, the groove width of each wide groove section 401 in the rod length direction L4 may vary. As shown in fig. 6, two groove side surfaces constituting the same wide groove section 401 may be arc cylindrical surfaces respectively, and the two groove side surfaces may extend to form the same cylindrical surface in the form of a grape hole.

Referring to fig. 4 to 7, the upper portion of the adjusting brace 4 may have a connecting plate, the connecting plate has a circular hole, the connecting plate is connected to the supporting connecting plate hole of the cross beam 2 by a shaft or a bolt, the middle of the lower portion is an extension slot 40 with a certain length, the width of the extension slot 40 may be slightly larger than the diameter of the fastening bolt 61, so that the locking bolt 61 can freely slide in the extension slot 41, meanwhile, a continuous grape hole with a certain interval is arranged in the length direction of the extension slot 40, and the diameter of the grape hole may be slightly larger than the width of the extension slot. The length of the extension groove can meet the angle adjusting range of the bracket. The base of the post 1 for connecting the adjusting stay 4 may be welded with a hexagon socket plate 7 as shown in fig. 6 on the back surface of the connecting part of the adjusting stay 4, and the hexagon socket plate 7 has a hexagon socket hole 71 to install the fastening bolt 61, so that the fastening nut 62 can be rotated without a wrench on the head of the fastening bolt 61.

One end of the fastening nut 62 can be a cylindrical section 621 in the form of a short cylinder, the middle part is a flange section 622, namely a flange type gasket, the other end is a hexagon nut 623, the inside can be a through thread 624, the diameter of the cylindrical section 621 can be slightly smaller than the diameter of a grape hole on the adjusting stay bar and is larger than the width of the extending groove, the fastening nut is used for connecting the adjusting stay bar 4 and the stand column 1, the adjusting stay bar 4 and the stand column 1 can be tightly screwed and pressed by a bolt corresponding to the nut on the fastening nut 62, the cylindrical section 621 can be embedded in the grape hole in the adjusting stay bar 4, relative sliding of the adjusting stay bar 4 is limited, the adjusting stay bar 4 is fixed in position, firm connection is realized, and meanwhile, the fastening nut 62 is convenient to operate, and fixing and loosening of the adjusting stay bar 4 can be realized only by screwing or unscrewing the fastening nut 62. The fastening member 6 may therefore also be referred to as a locking member.

The above-mentioned adjusting stay 4, the fastening member 6, etc. may be referred to as a stay device. When the manual inclination angle adjustable bracket 100 needs to be adjusted, the fastening nuts 62 on the bases of the upright posts 1 on both sides are firstly unscrewed, so that the adjusting stay bar 4 can slide up and down along the direction of the extension slot 40, then the middle two linked manual push rods 3 are rotated to adjust to a required angle, and then the fastening nuts 62 on the bases of the upright posts 1 on both sides are screwed, so that the adjusting stay bar 4 and the upright posts 1 are locked again, and the angle adjustment is completed. The manual inclination angle adjustable support 100 can adjust the installation inclination angle between the surface of the photovoltaic module 200 and the horizontal plane within the range of 0-70 degrees according to the change rule of the solar altitude angle, can realize single-person operation, is convenient to continuously adjust, and greatly improves the overall wind resistance of the support.

Referring to fig. 3, the angle of the manual push rod 3 and the adjusting stay 4 with respect to the column 1 may be different. This also increases the bearing stability.

The locking mode of the adjusting stay bar is as follows, the fastening nut is screwed, the cylindrical section of the fastening nut is simultaneously embedded into the grape hole of the adjusting stay bar, the fastening bolt is prevented from sliding in the extending groove of the adjusting stay bar, and the adjusting stay bar is locked on the stand column. When needs switch, the cylinder section is followed and is pulled out at the grape hole when loosening fastening nut soon, and the regulation vaulting pole can slide from top to bottom, locks fastening nut again after the adjustment position. The embedding or the extraction of the cylindrical section on the fastening nut and the locking or the unscrewing of the fastening nut are completed at one time, so that the switching efficiency is greatly improved. The adjusting stay bar is locked and supported, the wind resistance is extremely strong, but the adjustment is not convenient without a manual push rod. The manual push rod and the adjusting support rod are combined for use, so that the adjustment is convenient, the manual push rod can be prevented from being impacted by strong wind, the stability and the service life of the manual push rod can be greatly improved, and the integral wind resistance of the support can be further improved.

The sloping beam as the cross beam 2 may support purlin pieces 5, with photovoltaic modules 200 supported on the purlin pieces 5. The rotation axis O1 of the sloping with respect to the vertical column 1 is located above the main body 21 of the sloping, and the rotation axis O1 is located at a central position in the elongation direction L2 of the sloping, whereby the center of gravity of the rotating portion of the manual reclining bracket 100, which rotates with the sloping with respect to the vertical column 2, coincides with the rotation axis O1. It is understood that the rotating portion includes the oblique beam itself as the cross beam 2, the purlin members 5, the photovoltaic module 200, and various connectors, etc. It will also be appreciated that the centre of gravity coincides with the axis of rotation O1, i.e. the centre of gravity lies on the axis of rotation O1 of the rotating part, and that a range of errors is also allowed, for example the distance between the centre of gravity and the axis of rotation O1 may be less than 5mm. Unless specifically stated otherwise, references herein to two directions being "perpendicular", "coincident", "parallel", etc. also do not require that the mathematically strict angular requirement be met, but rather allow for a range of tolerances, for example, within 20 ° compared to the mathematically required angle, whereas "in" a direction means within 45 ° and more preferably within 20 ° or even 5 ° of that direction.

The support can adopt a balanced support mode, so that the negative influence caused by additional bending moment of the rotating part of the support is fundamentally eliminated, and the tracking in the adjusting process is more portable and flexible.

In fig. 1, purlin condition 5 may include transverse purlins 51 extending in the east-west direction and longitudinal purlins 52 extending in the north-south direction. As shown in fig. 3, the transverse purlins 51 may be connected laterally to the stringers 2, the upper portions may be connected to the longitudinal purlins 52, and the upper portions of the longitudinal purlins 52 may be connected to the photovoltaic module 200. The transverse purlins 51 are C-shaped or square pipes, the longitudinal purlins are C-shaped or T-shaped sections, the upright posts 1 are H-shaped, C-shaped or rectangular sections, the inclined beams are square pipes, circular pipes, C-shaped steel or polygonal pipes, and the adjusting stay bars 4 are C-shaped, U-shaped or square pipe sections.

Meanwhile, the back surface is not shielded, so that the device is suitable for double-sided components.

As shown in fig. 9, the main body 21 of the oblique beam, i.e., the main portion of the oblique beam extending in the elongation direction L2, for example, the rotation axis O1 may be considered to be located above 90% of the portion of the oblique beam. For example, in fig. 9, the oblique beam as the cross beam 2 may have a connecting plate at the middle position P1, a bushing is provided above the connecting plate, and the connecting plate can be connected to the upper side of the upright post 1 by penetrating a rotating shaft, for example, a bushing is also provided above the upright post 1, so that the oblique beam and the components carried on the upper portion thereof can rotate around the rotating shaft, the two end portions of the oblique beam may have C-shaped or flat-shaped connecting plates, and the connecting plate may have mounting holes for connecting with the transverse purlins. The lower part in front of the oblique beam can be provided with a supporting connecting plate, the connecting plate is provided with a mounting hole which can be connected with a mounting hole above the manual push rod 3 or the adjusting support rod 4, and the position of the connecting plate can be determined according to the position and the length of the push rod or the support rod.

The lower part of the upright post 1 can be provided with a base connected with the manual push rod 3 or the adjusting support rod 4, and the side wall of the upright post 1 used for connecting the manual push rod 3 can be also provided with a hole used for penetrating the transmission rod 5.

In the illustrated embodiment, each row of manual inclination angle adjustable supports are arranged at intervals in the east-west direction by adopting a plurality of upright columns, the upper parts of the upright columns can be hinged with the oblique beam through single support bearings, and two transverse purlins are respectively installed at two ends of the oblique beam in a fixed connection mode. The longitudinal purlines are orthogonally arranged between the two transverse purlines, and the photovoltaic module is arranged on the longitudinal purlines. The manual push rod or the support rod is arranged between the oblique beam and the upright post on the south side, so that the oblique beam, the upright post and the manual push rod or the support rod form a stable triangular support.

The included angle between the surface of the photovoltaic module and the horizontal plane can track and rotate from 0 degrees to south, and for example, the effective range of the inclination angle is between 0 degrees and 65 degrees. The cross section of the rotating part of the bracket is symmetrically arranged in structure, and the center of gravity of the rotating part of the bracket is positioned between the photovoltaic module and the oblique beam on the center line of the cross section. The rotating center of the supporting rotating shaft at the upper part of the upright post is arranged to coincide with the gravity center of the rotating part of the bracket, but when the push rod driving force is large enough and the structural integrity of the bracket is strong, the gravity center of the rotating part of the bracket and the center of the rotating shaft can not completely coincide, but the distance between the gravity center and the center of the rotating shaft is as small as possible, so that the rotating part of the bracket is in a balanced supporting state or a quasi-balanced supporting state (namely, the additional bending moment generated by the rotating part of the bracket does not influence the adjustment driving). And a manual push rod on the upright post is used for driving the rotating part of the bracket to rotate, so that the angle of the photovoltaic module surface can reach a preset position. And the adjusting stay bar is used for increasing the anti-vibration capability of the support when encountering wind gusts, when the support reaches a preset angle, a lower hole of the adjusting stay bar and a hole of the stand column base are penetrated with bolts and locked by fastening nuts, the adjusting stay bar, the stand column and the inclined beam form a triangular whole, and the position of the support is locked. When strong wind comes, the support becomes a fixed support, and the rigid support of the adjusting stay bar and the locking force of the push rod act together to ensure that the upper support structure is not damaged by the strong wind.

Actually, when the sloping beam and the upright post are connected by adjusting the push rod, in the design, when the adjusting push rod reaches the longest length (i.e. the stroke reaches the maximum), the surface of the photovoltaic module is set at the minimum angle or a state smaller than the minimum angle, when the adjusting push rod contracts, the surface of the photovoltaic module rotates towards the south, and when the adjusting push rod reaches the shortest length (i.e. the stroke reaches the minimum), the included angle between the surface of the photovoltaic module and the horizontal plane reaches the design set limit inclination angle, and the limit tracking angle can be comprehensively considered and selected according to the arrangement interval of the photovoltaic array, the local longitude and latitude and the like, and is not more than 65 degrees, for example. Therefore, the effective stroke of the adjusting push rod such as an electric push rod can be fully utilized, and the tracking and limiting effects can be achieved. A plurality of adjusting push rods are connected through a transmission rod to realize synchronous movement, and the surfaces of the photovoltaic modules are all in the same plane when the support is adjusted.

The adjusting stay bar is arranged on the upright post except for the upright post provided with the manual push rod, so that the rotating part of the bracket can be prevented from vibrating when strong wind exists, one section of the adjusting stay bar is connected to the oblique beam, and the other end of the adjusting stay bar is connected to the base of the upright post. When the photovoltaic module is designed, stroke allowances can be reserved at the upper and lower stroke positions of the grape hole of the adjusting stay bar, namely when the surface of the photovoltaic module is just in the minimum angle state, the adjusting stay bar and the upright post fastening bolt are close to the lowest end position of the grape hole, the adjusting stay bar moves downwards along with the contraction of the manual push rod, and when the included angle between the surface of the photovoltaic module and the horizontal plane reaches the designed limit tracking angle, the adjusting stay bar and the upright post fastening bolt are close to the uppermost end position of the grape hole. Before the adjustment, the fastening nut is unscrewed, and after the adjustment, the fastening nut is screwed. Generally, the above-mentioned manual adjustable support in inclination operation is convenient, and adjusting speed is fast, and supporting structure is stable.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention are within the scope of the present invention, as defined by the claims.
