Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic installation technology, and more specifically, it relates to an adjustable tilt angle photovoltaic module mounting bracket. Background Technology

[0002] With the rapid development of the global new energy industry, photovoltaic power generation, as an important form of clean and renewable energy utilization, is finding increasingly widespread applications. A photovoltaic module mounting bracket is required during the installation process. Existing photovoltaic module mounting brackets typically consist of core components such as a fixed base, connecting frames, and support frames. During installation, a fixed base is first formed by pouring concrete, providing a stable foundation for the entire bracket system. Then, using bolts and other connectors, the connecting frames are sequentially fastened to the fixed base and the supporting frames, forming a complete load-bearing frame. Finally, multiple photovoltaic panels are neatly arranged and fixed to the surface of the support frame using bolts, ensuring that the photovoltaic modules can receive solar radiation at a preset angle.

[0003] Existing application number CN202321527495.4 discloses a photovoltaic module mounting bracket, including a fixed bracket and a movable bracket. A base plate is fixedly connected to the bottom of the fixed bracket, and a fixing block is fixedly connected to the front of the movable bracket. Photovoltaic panels are mounted on the surfaces of both the fixed and movable brackets. A groove is formed on the side of the photovoltaic panel near the fixing block. An adjustment mechanism, including a telescopic spring, is provided on the front of the fixing block. The top of the telescopic spring is fixedly connected to the fixing block. The beneficial effect of this utility model is that by pulling the handle upwards, the telescopic spring contracts, causing the movable bracket to move upwards, thus detaching the rubber pad from the base plate. Pulling the handle adjusts the distance between the fixed and movable brackets to the desired position. Releasing the handle allows the photovoltaic panel to be installed on the fixed and movable brackets, thus enabling the installation of photovoltaic panels of different sizes.

[0004] Based on the above, existing photovoltaic module mounting brackets mostly consist of fixed-size metal structures for their load-bearing frames. Due to significant differences in solar altitude angles across different latitudes and longitudes, photovoltaic modules require different installation tilt angles to maximize sunlight utilization. This necessitates the use of brackets of various sizes to adapt to different scenarios. Therefore, the diverse brackets not only increase the difficulty of categorized storage but also raise the cost of warehousing space and management complexity. Furthermore, in rainy and humid regions, the bracket fixing bolts are prone to corrosion due to prolonged exposure to high humidity, which not only reduces tightening performance and affects bracket stability but also increases the difficulty of maintenance and disassembly, and even raises operation and maintenance costs due to frequent bolt replacements. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable tilt photovoltaic module mounting bracket, which solves the problem that existing photovoltaic module mounting brackets mostly have fixed-size metal structures for their load-bearing frames. Due to significant differences in solar altitude angles across different latitudes and longitudes, photovoltaic modules need to be installed at different tilt angles to maximize sunlight utilization. This necessitates the use of brackets of various sizes to adapt to different scenarios. Therefore, the diverse brackets not only increase the difficulty of categorized storage but also raise the cost of warehousing space and management complexity. Furthermore, in rainy and humid areas, the bracket fixing bolts are prone to corrosion due to prolonged exposure to high humidity, which not only reduces fastening performance and affects bracket stability but also increases the difficulty of maintenance and disassembly, and even raises maintenance costs due to frequent bolt replacements.

[0006] The purpose and effect of this utility model, an adjustable tilt angle photovoltaic module mounting bracket, are achieved by the following specific technical means: An adjustable tilt photovoltaic module mounting bracket includes a fixed base, a front mounting bracket, a rear mounting bracket, a first support bracket, a second support bracket, a mounting frame, an adjustment component, and a protective component.

[0009] Furthermore, the protective component includes: mounting holes and sliding grooves. The mounting holes are provided in multiple sets, which are respectively opened inside the front mounting bracket, the rear mounting bracket, the first support bracket, and the mounting frame. The sliding grooves are provided in multiple sets, which are respectively opened inside the front mounting bracket, the rear mounting bracket, the first support bracket, and the mounting frame.

[0010] Furthermore, the protective component also includes: fixing bolts and limiting grooves, wherein multiple sets of fixing bolts are provided and multiple sets of fixing bolts are installed inside multiple sets of mounting holes; multiple sets of limiting grooves are provided and multiple sets of limiting grooves are respectively opened on the outside of multiple sets of fixing bolts.

[0011] Furthermore, the protective assembly also includes: a transmission plate and a sealing plate, wherein multiple sets of transmission plates are provided, and the multiple sets of transmission plates are slidably connected inside multiple sets of sliding grooves; and multiple sets of sealing plates are provided, and the multiple sets of sealing plates are fixedly installed on the top of the multiple sets of transmission plates.

[0012] Furthermore, the protective component also includes: a limiting block and a return spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this invention features an adjustment component. Height adjustment is achieved by sliding a sliding rod within the second support frame, which in turn rotates the first support frame to change the tilt angle of the mounting frame. Combined with multiple sets of limiting holes and bolts for fixation, it can flexibly adapt to the solar altitude angle requirements of different latitude and longitude regions. Simultaneously, the reinforcing rod, through its cooperation with the first limiting hole, forms an oblique support, improving structural stability. This eliminates the need for various sized supports, reducing storage difficulty and management costs.

[0014] Secondly, this invention features a protective component. A return spring drives a sealing plate to automatically seal the mounting hole, isolating moisture and impurities to reduce the risk of bolt corrosion. The locking mechanism between the limiting block and the outer limiting groove of the bolt forms a mechanical locking structure, preventing the bolt from loosening due to vibration. The localized opening design at key connection points reduces machining and material consumption while ensuring strength, thus lowering production costs.

[0015] This invention has the advantages of easy adjustment, stable support, and convenient maintenance. It is suitable for various terrains and climates, and extends the service life of equipment while reducing operation and maintenance costs. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0023] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides an adjustable tilt photovoltaic module mounting bracket, including a fixed base 1, a front mounting bracket 2, a rear mounting bracket 3, a first support bracket 4, a second support bracket 5, a mounting frame 6, and an adjustment component. The front mounting bracket 2 is fixedly installed inside the fixed base 1; the rear mounting bracket 3 is fixedly installed inside the fixed base 1; the top end of the first support bracket 4 is hinged to the inside of the front mounting bracket 2; the end of the second support bracket 5 is hinged to the inside of the rear mounting bracket 3; the mounting frame 6 is bolted to the upper part of the first support bracket 4; and the adjustment component is disposed on the upper part of the fixed base 1.

[0024] The adjustment assembly includes a reinforcing rod 401 and a limiting head 402. The end of the reinforcing rod 401 is hinged inside the rear mounting bracket 3. The limiting head 402 is fixedly installed on the top of the reinforcing rod 401.

[0025] The adjustment assembly also includes: a first limiting hole 403, a sliding rod 501, and a second limiting hole 502. Multiple sets of first limiting holes 403 are provided, and multiple sets of first limiting holes 403 are opened inside the first support frame 4. The sliding rod 501 is slidably connected inside the second support frame 5, and the top end of the sliding rod 501 is hinged to the end of the first support frame 4. Multiple sets of second limiting holes 502 are provided, and multiple sets of second limiting holes 502 are opened inside the sliding rod 501.

[0026] The specific usage and function of this embodiment are as follows: When the tilt angle of the mounting frame 6 needs to be adjusted according to the lighting conditions in different regions to achieve efficient light collection by the photovoltaic panels, the sliding rod 501 is first stretched so that it slides along the inside of the second support frame 5 to adjust the height. As the sliding rod 501 extends and retracts, the first support frame 4, which is hinged at its top, will rotate synchronously until the mounting frame 6 reaches the preset optimal tilt angle. At this time, the bolt is passed through the preset hole at the top of the second support frame 5 and fastened to the corresponding second limiting hole 502 on the sliding rod 501, thus completing the relative fixation of the sliding rod 501 and the second support frame 5. Subsequently, the reinforcing rod 401 is swung to the appropriate angle, and the bolt is passed through the reserved hole of the limiting head 402 at the top of the reinforcing rod 401 and locked and fixed with the first limiting hole 403 at the corresponding position on the first support frame 4. The oblique support of the reinforcing rod 401 can significantly improve the structural stability and load-bearing capacity of the first support frame 4 and avoid tilting deviation caused by the self-weight of the photovoltaic panel or external load. Example 2

[0027] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a protective component, which is disposed on the upper part of the fixed base 1.

[0028] The protective components include: mounting holes 7 and sliding grooves 8. Multiple sets of mounting holes 7 are provided, and the multiple sets of mounting holes 7 are respectively opened inside the front mounting frame 2, the rear mounting frame 3, the first support frame 4 and the mounting frame 6. Multiple sets of sliding grooves 8 are provided, and the multiple sets of sliding grooves 8 are respectively opened inside the front mounting frame 2, the rear mounting frame 3, the first support frame 4 and the mounting frame 6.

[0029] The protective component also includes: fixing bolts 701 and limiting grooves 702. Multiple sets of fixing bolts 701 are provided, and multiple sets of fixing bolts 701 are installed inside multiple sets of mounting holes 7. Multiple sets of limiting grooves 702 are provided, and multiple sets of limiting grooves 702 are respectively opened on the outside of multiple sets of fixing bolts 701.

[0030] The protective components also include: a transmission plate 801 and a sealing plate 802. Multiple sets of transmission plates 801 are provided, and the multiple sets of transmission plates 801 are slidably connected inside multiple sets of sliding grooves 8. Multiple sets of sealing plates 802 are provided, and the multiple sets of sealing plates 802 are fixedly installed on the top of the multiple sets of transmission plates 801.

[0031] The protective components also include: a limiting block 803 and a return spring 804. Multiple sets of limiting blocks 803 are provided, and the multiple sets of limiting blocks 803 are respectively fixedly installed on the left side of multiple sets of transmission plates 801. Multiple sets of return springs 804 are provided, and one end of each set of return springs 804 is fixedly connected to the inner side of the transmission plate 801 on the same side, and the other end of each set of return springs 804 is fixedly connected to the inside of the sliding groove 8 on the same side.

[0032] The specific usage and function of this embodiment are as follows: In its natural state, the preload of the return spring 804 pushes the transmission plate 801 inward along the sliding groove 8 until the sealing plate 802 completely covers the mounting hole 7, forming a physical barrier to prevent moisture and dust from entering. When component connection is required, the sealing plate 802 is pushed outward to compress the return spring 804, fully exposing the mounting hole 7. At this time, the fixing bolt 701 can be passed through the mounting hole 7 and screwed into the threaded hole of the corresponding component, completing key connection operations such as connecting the photovoltaic panel to the mounting frame 6.

[0033] After tightening, the sealing plate 802 is loosened, and the elastic restoring force of the return spring 804 drives the transmission plate 801 to reset, causing the sealing plate 802 to re-seal the mounting hole 7. Simultaneously, the limiting block 803 on the outer side of the transmission plate 801 precisely engages in the limiting groove 702 of the fixing bolt 701, forming a circumferential constraint. This structural design not only effectively isolates external corrosive media but also significantly improves the bolt's vibration resistance through a mechanical interlocking mechanism, ensuring long-term reliability of the connection under complex working conditions such as strong winds and temperature variations.

[0034] Specifically, mounting holes 7 and sliding grooves 8 are only opened at key connection positions between the first support frame 4 and the mounting frame 6, such as load-bearing nodes that are in direct contact with the photovoltaic panel and the mounting frame 6, and load-bearing nodes between the first support frame 4 and the mounting frame 6. The remaining positions are fixed with ordinary bolts. This local optimization design reduces processing time and material waste while ensuring structural strength.

[0035] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0036] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment. Therefore, the protection scope of this embodiment should be determined by the protection scope of the claims.
