Description

Technical Field

[0001] The invention belongs to the field of photovoltaic brackets. Background Art

[0002] The side facade (exterior facade) of the building has a certain lighting area. If it can be utilized, it can effectively make up for the insufficient installation area caused by limited space on the roof of a high-rise building, thereby improving the overall energy utilization efficiency of the building. Due to the vertical structural characteristics of the side facade of the building, in order to facilitate debugging and maintenance, the driving structure used to drive the change of the elevation and azimuth of the photovoltaic panels is best at the bottom or top of the building. Therefore, the azimuth adjustment and elevation adjustment systems of the photovoltaic bracket need to be redesigned to ensure the stability and wind resistance of the light chasing, so as to truly play its due performance. Summary of the invention

[0005] The azimuth and elevation synchronous adjustment shaft has a number of thread segments distributed from top to bottom, there is a bare rod segment between any two adjacent thread segments, and the thread rotation directions of any two adjacent thread segments are opposite; the upper and lower adjacent thread segments are respectively recorded as an upper thread segment and a lower thread segment;

[0006] The bracket unit includes an upper holding tube, a lower holding tube, a first swing arm and a second swing arm; an upper transmission nut and a lower transmission nut are coaxially fixed in the upper holding tube and the lower holding tube respectively; the upper transmission nut and the lower transmission nut are threadedly matched with the upper thread section and the lower thread section respectively.

[0007] Furthermore, an upper fixing sleeve and a lower fixing sleeve are coaxially rotatably mounted outside the polished rod section between the upper threaded section and the lower threaded section through a bearing; the upper fixing sleeve and the lower fixing sleeve are fixed structures.

[0009] Furthermore, a first hinge hole is arranged at the upper end of the second swing arm, and a second hinge hole is arranged at the middle part of the first swing arm. Both the first hinge hole and the second hinge hole are hinged on the same floating hinge shaft.

[0010] Furthermore, from the axial perspective of hinge a, hinge b and floating hinge axis, the connecting lines of hinge a, hinge b and floating hinge axis form an isosceles triangle, and the length of the connecting line between hinge a and floating hinge axis is equal to the length of the connecting line between hinge b and floating hinge axis.

[0011] Furthermore, a lock ring is rotatably installed on a section of the bare rod between the upper fixed sleeve and the lower fixed sleeve through a bearing; a plurality of lock holes are distributed in a fan-shaped array on the edge of the lock ring, a vertical electromagnetic retractor is fixedly installed on one side of the upper fixed sleeve, and a retractable tongue is provided at the lower end of the electromagnetic retractor. During the rotation of the lock around the axis, the plurality of lock holes correspond to the retractable tongue above one by one, and the retractable tongue extends downward into the corresponding lock hole;

[0012] A pair of horizontal and parallel adaptive telescopes are fixedly installed on both sides of the locking ring through a fixing seat. Under normal conditions, the telescopic rods of the adaptive telescopes adaptively extend and retract under the action of external force. The adaptive telescopes are provided with a locking device that can lock the telescopic rods; the ends of the two telescopic rods are respectively and vertically fixedly connected to the two ends of the floating hinge shaft.

[0013] Furthermore, a photovoltaic panel mounting plate is fixedly mounted parallel to the outer side of the first swing arm, and a photovoltaic panel can be fixedly mounted on the photovoltaic panel mounting plate.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] As attached Figures 1 to 5 The azimuth and elevation synchronous adjustment system of the photovoltaic panel bracket shown includes a vertical wall fixing plate 3, which is longitudinally fixed on the facade of the building, and also includes an azimuth-elevation synchronous adjustment axis 4 parallel to the wall fixing plate 3. The driving device at the upper or lower end of the azimuth-elevation synchronous adjustment axis 4 can drive the azimuth-elevation synchronous adjustment axis 4 to rotate along the axis; a plurality of bracket units 2 are evenly distributed on the azimuth-elevation synchronous adjustment axis 4 from top to bottom; the driving device can be a driving motor installed at the top or bottom of the building. The feature of this case is that the driving device is at the top and bottom of the building, which is conducive to maintenance. At the same time, one motor as the main power device can simultaneously control the elevation and azimuth of several bracket units 2. The detailed structure is as follows.

[0028] like Figures 2 to 5The azimuth and elevation synchronous adjustment shaft 4 is provided with a plurality of threaded sections 6 distributed from top to bottom, and there is a bare rod section 5 between any two adjacent threaded sections 6, and the threaded rotation directions of any two adjacent threaded sections 6 are opposite; the upper and lower adjacent threaded sections 6 are respectively recorded as an upper threaded section 6.1 and a lower threaded section 6.2; the bare rod section 5 between the upper threaded section 6.1 and the lower threaded section 6.2 is provided with an upper fixing sleeve 32 and a lower fixing sleeve 27 for coaxial rotation through a bearing, and the upper fixing sleeve 32 and the lower fixing sleeve 27 are fixed structures; the upper fixing sleeve 32 and the lower fixing sleeve 27 are respectively fixedly connected to the wall fixing plate 3 through an upper fixing arm 12 and a lower fixing arm 13.

[0029] The bracket unit 2 includes an upper holding tube 10, a lower holding tube 15, a first swing arm 19 and a second swing arm 18; a photovoltaic panel mounting plate 33 is fixedly installed parallel to the outer side of the first swing arm 19, and a photovoltaic panel can be fixedly installed on the photovoltaic panel mounting plate 33; an upper transmission nut 34 and a lower transmission nut 35 are coaxially fixed in the upper holding tube 10 and the lower holding tube 15 respectively; the upper transmission nut 34 and the lower transmission nut 35 are threadedly matched with the upper thread segment 6.1 and the lower thread segment 6.2 respectively; the upper holding tube 10 and An upper clamp 8 and a lower clamp 16 are fixedly mounted on the outside of the lower clamp tube 15; the upper end of the oblique first swing arm 19 is hinged to the outer wall of the upper clamp 8 through a hinge 9; the lower end of the oblique second swing arm 18 is hinged to the outer wall of the lower clamp 16 through a hinge 17; a first hinge hole 21 is provided at the upper end of the second swing arm 18, and a second hinge hole 20 is provided in the middle of the first swing arm 19, and the first hinge hole 21 and the second hinge hole 20 are both hinged on the same floating hinge shaft 22.

[0030] Attached Figure 2 , from the axial perspective of the a-hinge 9, the b-hinge 17 and the floating hinge shaft 22, the connecting lines of the a-hinge 9, the b-hinge 17 and the floating hinge shaft 22 form an isosceles triangle, and the connecting length of the a-hinge 9 and the floating hinge shaft 22 is equal to the connecting length of the b-hinge 17 and the floating hinge shaft 22; under the restriction of this geometric relationship, no matter whether the upper holding tube 10 and the lower holding tube 15 move closer to or farther away from each other, the height of the floating hinge shaft 22 remains unchanged.

[0031] A lock ring 30 is rotatably mounted on the outside of a section of the bare rod section 5 between the upper fixed sleeve 32 and the lower fixed sleeve 27 through a bearing; a plurality of lock holes 28 are distributed in a fan-shaped array on the edge of the lock ring 30, and a vertical electromagnetic retractor 31 is fixedly mounted on one side of the upper fixed sleeve 32, and the lower end of the electromagnetic retractor 31 is a retractable tongue 29. During the rotation of the lock ring 30 around the axis, the plurality of lock holes 28 correspond to the retractable tongue 29 above one by one, and the retractable tongue 29 extends downward into the corresponding lock hole 28; a pair of horizontal and parallel adaptive retractors 25 are fixedly mounted on both sides of the lock ring 30 through a fixed seat 26. Under normal conditions, the telescopic rod 23 of the adaptive retractor 25 is adaptively extended and retracted under the action of external force. A locking device capable of locking the telescopic rod 23 is provided on the adaptive retractor 25. When the telescopic rod 23 is locked, it cannot be freely extended and retracted, and its locking device is controlled by a controller; the ends of the two telescopic rods 23 are respectively vertically fixedly connected to the two ends of the floating hinge shaft 22, and the adaptive retractor 25 does not need to do external work during the adaptive extension and retraction process.

[0032] Working principle:

[0033] Elevation adjustment:

[0034] Taking a single bracket unit 2 as an example, in the initial state, the telescopic tongue 29 of the electromagnetic telescope 31 extends downward into a lock hole 28 on the lock ring 30, so that the lock ring 30 enters a locked state where it cannot rotate. Once the lock ring 30 cannot rotate, the upper and lower holding tubes 10 and 15 and the upper transmission nuts 34 and lower transmission nuts 35 in the upper and lower holding tubes 10 and 15 cannot rotate around the axis, so that the photovoltaic panel mounting plate 33 cannot rotate around the axis of the upper and lower holding tubes 10 and 15, thereby achieving the locking state. The azimuth of the photovoltaic panel mounting plate 33 is fixed; at this time, if the driving device does not drive the azimuth elevation synchronous adjustment shaft 4 to rotate, the photovoltaic panel mounting plate 33 is in a stationary state; if the driving device drives the azimuth elevation synchronous adjustment shaft 4 to rotate, since the thread rotation directions of any two adjacent thread segments 6 are opposite, and since the upper transmission nut 34 and the lower transmission nut 35 in the upper holding tube 10 and the lower holding tube 15 cannot rotate, under the action of the thread transmission, the upper holding tube 10 and the lower holding tube 15 will move in opposite directions of approaching or moving away from each other. The movement of the a-joint 9, the b-joint 17 and the floating hinge shaft 22 is carried out, and because the connecting lines of the a-joint 9, the b-joint 17 and the floating hinge shaft 22 form an isosceles triangle from the axial perspective of the a-joint 9, the b-joint 17 and the floating hinge shaft 22, and the length of the connecting line of the a-joint 9 and the floating hinge shaft 22 is equal to the length of the connecting line of the b-joint 17 and the floating hinge shaft 22. Under the restriction of the geometric relationship, no matter the upper holding tube 10 and the lower holding tube 15 move closer to or farther from each other, the height of the floating hinge shaft 22 remains unchanged, and the expansion and contraction of the adaptive telescoping device 25 is The rod 23 is adaptively extended and retracted; therefore, under the rotation drive of the azimuth and elevation synchronous adjustment shaft 4: when the upper holding tube 10 and the lower holding tube 15 move towards each other, the first swing arm 19 swings upward around the a-joint 9, and the telescopic rod 23 of the adaptive telescopic device 25 is adaptively extended; when the upper holding tube 10 and the lower holding tube 15 move away from each other, the first swing arm 19 swings downward around the a-joint 9, and the telescopic rod 23 of the adaptive telescopic device 25 is adaptively shortened; thereby realizing the elevation adjustment of the first swing arm 19.

[0035] Azimuth adjustment;

[0036] Taking a single bracket unit 2 as an example, the adaptive telescopic device 25 is first controlled to lock the telescopic rod 23, and then the telescopic tongue 29 of the electromagnetic telescopic device 31 is controlled to retract upward, thereby releasing the locking state of the lock ring 30; at this time, since the telescopic rod 23 in the locked state cannot be adaptively extended and retracted, the position of the floating hinge shaft 22 is fixed, and since the rotation directions of the upper transmission nut 34 and the lower transmission nut 35 are opposite, the upper transmission nut 34, the lower transmission nut 35, the upper clamp 10, the lower clamp 15, the upper clamp 8, the lower clamp 16, the first swing arm 19, the second swing arm 18, the adaptive telescopic device 25 and the lock ring 30 together constitute a mutually synchronized interlocking structure; at this time, if the driving device does not drive the azimuth elevation synchronous adjustment shaft 4 to rotate, the photovoltaic panel The mounting plate 33 is in a stationary state; if the driving device drives the azimuth-elevation synchronous adjustment shaft 4 to rotate, the upper transmission nut 34, the lower transmission nut 35, the upper clamping tube 10, the lower clamping tube 15, the upper clamping hoop 8, the lower clamping hoop 16, the first swing arm 19, the second swing arm 18, the adaptive telescopic device 25 and the locking ring 30 together constitute a mutually synchronized interlocking structure and synchronously rotate around the axis of the azimuth-elevation synchronous adjustment shaft 4, thereby realizing the azimuth adjustment of the first swing arm 19; it should be noted that the azimuth adjustment in this case is not an infinitely variable adjustment (if necessary, it can also be designed as an infinitely variable adjustment structure). At the end of each azimuth adjustment, a lock hole 28 on the locking ring 30 is required to be aligned with the telescopic tongue 29, so as to facilitate switching to the "elevation adjustment" mode.

[0037] The process of synchronously adjusting axis 4 in the windproof state with locked azimuth and elevation:

[0038] In severe windy weather, it is necessary to suspend the elevation adjustment and azimuth adjustment processes. At the same time, in order to prevent the azimuth elevation synchronous adjustment shaft 4 from being forced to rotate under the influence of strong environmental wind, taking a single bracket unit 2 as an example, on the basis of controlling the adaptive telescopic device 25 to lock the telescopic rod 23, the telescopic tongue 29 of the electromagnetic telescopic device 31 extends downward into a lock hole 28 on the locking ring 30; thereby, the upper transmission nut 34, the lower transmission nut 35, the upper clamping tube 10, the lower clamping tube 15, the upper clamping hoop 8, the lower clamping hoop 16, the first swing arm 19, the second swing arm 18, the adaptive telescopic device 25 and the locking ring 30 together constitute a mutually synchronized interlocking structure that is synchronized with the upper fixed sleeve 32 in the fixed state, thereby achieving the effect of locking the azimuth elevation synchronous adjustment shaft 4.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
