[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, a fixed adjustable photovoltaic (PV) bracket includes a mounting component 3, a support component 1, and an adjusting component 2. The support component 1 serves as the bottom support structure of the PV bracket. The mounting component 3 is positioned above the support component 1, with its lower part hinged to one end of the support component 1, and is used to mount PV panels. The adjusting component 2 is positioned between the support component 1 and the mounting component 3, and is hinged to both the support component 1 and the mounting component 3. The adjusting component 2 is used to adjust and fix the angle between the mounting component 3 and the support component 1. This design allows the PV bracket to combine the advantages of adjustable tilt angle for power generation gain with structural stability, enabling flexible adjustment and reliable fixation of the angle between the mounting component 3 and the support component 1, adapting to changes in solar altitude angle in different seasons and the irradiance conditions of the project site.

[0028] In this embodiment, the adjusting member 2 includes a first rear column 24, a second rear column 23, a third rear column 25, a push rod 21, and a locking part 22. The push rod 21 is an existing electric / manual adjusting component capable of length adjustment. The lower end of the first rear column 24 and the upper end of the second rear column 23 are hinged to one end of the push rod 21, and the other end of the push rod 21 is hinged to the support member 1. The upper end of the first rear column 24 is hinged to the mounting member 3. The upper end of the third rear column 25 is hinged to the first rear column 24. The lower end of the second rear column 23 is hinged to the support member 1. Two locking parts 22 are provided. One locking part 22 is mounted on the support member 1 to limit the lower end of the third rear column 25 to the support member 1. The other locking part 22 is mounted on the second rear column 23 to limit the lower end of the third rear column 25 to the second rear column 23. The hinged linkage design of multiple rear columns, combined with the limiting function of two locking parts 22, improves the stability of the bracket adjustment process and the structural strength after locking, effectively resists the overturning moment generated by high wind pressure, avoids structural deformation, breakage or loosening, and is suitable for high wind pressure environments.

[0029] In this embodiment, the locking part 22 includes a base 223 and a locking tongue 224; the base 223 and the locking tongue 224 are hinged together by a pin 227; a torsion spring is sleeved on the pin 227, one end of the torsion spring is fixed to the base 223, and the other end is fixed to the locking tongue 224; a first locking groove 222 is provided on the base 223, and a second locking groove 221 that cooperates with the first locking groove 222 is provided on the locking tongue 224; a locking rod is fixedly provided at the lower end of the third rear column 25; the locking rod is inserted into the first locking groove 222 and the second locking groove 221, and the locking rod is restricted to the base 223 by the locking tongue 224. The elastic force of the torsion spring ensures a tight fit between the locking tongue 224 and the base 223, achieving a stable fixation of the locking rod of the third rear column 25. At the same time, the hinge structure ensures smooth locking and unlocking actions, avoiding jamming, wear, or locking problems caused by wind and sand intrusion, adapting to windy and sandy environments, and reducing the failure rate of operation and maintenance.

[0030] In this embodiment, an arc-shaped guide surface 226 is provided on the end face of the latch 224 near the first lock groove 222, with one end of the arc-shaped guide surface 226 facing inward towards the first lock groove 222. When it is necessary to fix the locking rod of the third rear column 25 through the locking part 22, the locking rod of the third rear column 25 is placed on the arc-shaped guide surface 226. Relying on the weight of the third rear column 25, pressure is applied to the inward direction of the second lock groove 221 through the locking rod. When the locking rod of the third rear column 25 presses against the arc-shaped guide surface 226, the locking rod slides relative to the arc-shaped guide surface 226, and the latch rotates around the axis of the pin 227. The opening directions of the first locking groove 222 and the second locking groove 221 gradually coincide until the locking rod enters the first locking groove and the second locking groove. The torsion spring drives the locking tongue 224 to rotate and reset. The openings of the first locking groove 222 and the second locking groove 221 are misaligned. The weight of the third rear column 25 is transferred to the locking rod, pressing the locking tongue 224 against the base 223 to complete the self-locking of the locking part 22. During the installation process, the locking tongue 224 does not need to be manually opened to achieve the locking and fixing of the third rear column 25. When it is necessary to move the locking rod of the third rear column 25 out of the locking part 22, the locking tongue 224 can be manually lifted to move the locking rod of the third rear column 25 out of the locking part 22.

[0031] In this embodiment, the locking part 22 further includes a first linkage member 225. When multiple photovoltaic brackets are used in parallel intervals, the locking tongues 224 at corresponding positions on the adjusting member 2 are connected in series and fixed by the first linkage member 225, controlling the synchronous movement of multiple locking tongues 224. This enables the synchronous movement of the locking tongues 224 of multiple photovoltaic brackets arranged in parallel intervals, significantly improving the operational efficiency of angle adjustment and reducing the intensity of manual operation. At the same time, the self-weight of the first linkage member 225 applies a pre-tightening force, strengthening the locking reliability of the locking part 22 and further improving the wind resistance performance of the bracket in the locked state.

[0032] In this embodiment, the adjusting component 2 also includes a second linkage component 26; when multiple photovoltaic brackets are used in parallel intervals, the third rear column 25 at the corresponding position on the adjusting component 2 is connected in series and fixed by the second linkage component 26, so as to control the synchronous movement of multiple third rear columns; the operator only needs to pull the second linkage component 26 to synchronously control the movement of multiple third rear columns 25, which makes it easy to switch the setting angle of the fixed adjustable photovoltaic bracket.

[0033] In this embodiment, both the first linkage component 225 and the second linkage component 26 are square tubes.

[0034] In this embodiment, the mounting component 3 includes a purlin 32 and a diagonal beam 31; the diagonal beam 31 is used to connect the adjusting component 2 and the supporting component 1; the purlin 32 is fixed on the diagonal beam 31 and used to install the photovoltaic panel. The diagonal beam 31 achieves a stable connection between the adjusting component 2 and the supporting component 1, provides a solid installation foundation for the purlin 32, ensures the structural integrity of the photovoltaic panel after installation, and ensures the continuity of the photovoltaic power generation process.

[0035] In this embodiment, multiple purlins 32 are configured; the multiple purlins 32 are arranged in parallel at intervals along the length direction of the inclined beam 31. This increases the connection area between the photovoltaic panel and the mounting component 3, improves the stability of the photovoltaic panel installation, ensures that the photovoltaic panel is not easily detached in extreme environments, and optimizes the stress distribution of the photovoltaic panel to ensure the stability of the photovoltaic power generation process.

[0036] In this embodiment, the support member 1 includes a first base 14, a second base 11, a front column 13, and a diagonal brace 12; the first base 14 and the second base 11 are spaced apart; the lower end of the front column 13 is fixed to the first base 14; one end of the diagonal brace 12 is hinged to the second base 11, and the other end is hinged to the upper part of the front column 13; the upper end of the front column 13 is hinged to the mounting member 3 and the adjusting member 2. Through the spaced arrangement of the bases and the supporting effect of the diagonal brace 12, the overall load-bearing capacity and anti-overturning performance of the support member 1 are enhanced, providing a stable support foundation for the mounting member 3 and the adjusting member 2, ensuring long-term stable operation of the support under high wind pressure.

[0037] Working principle:

[0038] This fixed adjustable photovoltaic bracket achieves dual-angle switching adjustment between the mounting component 3 and the support component 1 through the adjusting component 2. When switching from a large angle to a small angle, the locking part 22 installed on the second rear column 23 is unlocked, the third rear column 25 is released, and the push rod 21 is driven to rotate, causing the first rear column 24 and the second rear column 23 to move synchronously. After rotating to the preset angle, the locking rod of the third rear column 25 is inserted into the first locking groove 222 and the second locking groove 221 of the locking part 22 installed on the support component 1. The locking rod is fixed to the base 223 by the locking tongue 224, completing the locking after the small angle adjustment, as shown in the figure. Figure 5As shown. When switching from a small angle to a large angle, first unlock the locking part 22 installed on the support 1, release the third rear column 25, drive the push rod 21 to rotate, causing the first rear column 24 and the second rear column 23 to move synchronously; after rotating to the preset angle, insert the locking rod of the third rear column 25 into the first locking groove 222 and the second locking groove 221 of the locking part 22 installed on the second rear column 23, and fix the locking rod to the base 223 by the locking tongue 224, completing the locking after the large angle adjustment, as shown. Figure 6 As shown. When multiple photovoltaic brackets are used in parallel intervals, the first linkage component 225 connects and fixes the locking tongues 224 at corresponding positions on each adjusting component 2 in series, so as to realize the synchronous movement of multiple locking tongues 224. In the non-operating state, the self-weight of the first linkage component 225 applies a pre-tightening force to the locking structure to ensure the reliability of locking.
