Description

Technical Field

[0001] This utility model relates to the field of mountain photovoltaic support technology, specifically an angle-adjustable mountain photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting brackets are special supports used to place, install, and fix solar panels in a solar photovoltaic (PV) power generation system. They support the main power generation component of the PV power plant and are an important part of the system. The design of PV mounting brackets needs to consider geographical location, climate, and solar energy resource conditions to ensure that the PV modules are arranged and fixed in the optimal orientation and angle.

[0003] Chinese utility model patent CN219893252U discloses a photovoltaic bracket, including a limiting support plate. The limiting support plate is movably hinged to an adjusting support device consisting of an angle adjusting cylinder and an electric telescopic rod. Two support blocks are symmetrically arranged on the limiting support plate, and several water guide grooves are evenly formed within each support block. A limiting device is located inside each water guide groove. A positioning plate adapted to the angle adjusting cylinder is provided at the bottom of the limiting support plate, and several adjusting through holes adapted to positioning through holes are formed on the positioning plate. This design aims to solve the problems of inconvenient installation, maintenance, and replacement of solar panels, as well as angle adjustment issues. Specifically, it uses a pneumatic method to drive the angle adjusting cylinder to change the tilt angle of the solar panel, and uses an electric telescopic rod for locking and positioning.

[0004] However, this technical solution still has the following drawbacks:

[0005] 1. Complex structure, high cost and dependence on external energy: Its angle adjustment relies on power components such as pneumatic cylinders and electric telescopic rods, which not only increases the complexity and manufacturing cost of the system, but also requires a location with air or electricity to operate, which greatly limits its application in remote mountainous environments lacking infrastructure.

[0006] 2. Inconvenient maintenance: Pneumatic and electric components are prone to failure in harsh outdoor environments (such as wind, rain, sand, high and low temperatures), requiring high maintenance and increasing the cost and difficulty of later operation and maintenance. Overall reliability is insufficient for long-term mountain applications.

[0007] 3. Inconvenient angle adjustment: When adjusting the angle, not only does the angle adjustment cylinder need to extend and retract, but the electric telescopic rod also needs to be selectively inserted into the adjustment through hole. This presents the problem that the extension and retraction height of the adjustment cylinder must meet the alignment of the electric telescopic rod with the corresponding adjustment through hole, which makes angle adjustment inconvenient. Utility Model Content

[0008] The purpose of this invention is to provide an angle-adjustable photovoltaic support for mountainous areas, in order to solve the problems of high cost and inconvenient angle adjustment of photovoltaic panels in existing technologies.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an angle-adjustable mountain photovoltaic support bracket, comprising a connecting base plate and a mounting bracket for installing photovoltaic panels. A vertically extending support column is fixed at one end of the connecting base plate, and a vertically extending stabilizing column is fixed at the other end. The mounting bracket is supported on the top of the support column and the stabilizing column. The support column includes a first connecting column and a second connecting column axially movably fitted inside the first connecting column. The second connecting column has multiple positioning grooves along its length extension direction. Limiting holes are opened on the first connecting column at positions corresponding to the positioning grooves. Limiting bolts pass through the limiting holes and lock the first connecting column and the second connecting column with the corresponding positioning grooves. A bearing block is rotatably connected to the top of the stabilizing column. The mounting bracket is supported on the bearing block and detachably connected to the bearing block. A limiting block is rotatably connected to the top of the second connecting column. A sliding groove adapted to the limiting block is provided at the bottom of the mounting bracket. The limiting block is movably inserted into the sliding groove.

[0010] Furthermore, a rubber sealing ring is provided between the top end of the first connecting post and the second connecting post, and the rubber sealing ring is engaged with the first connecting post.

[0011] Furthermore, the positioning grooves are equally spaced on the second connecting post.

[0012] Furthermore, the mounting bracket includes a mounting support rod and a stabilizing support rod. The stabilizing support rod is provided on both sides of both ends of the mounting support rod. All stabilizing support rods are coplanar and each stabilizing support rod is inclined to the mounting support rod. The opposite ends of the stabilizing support rods connected to the mounting support rods are provided with mounting screws. The sliding groove is provided at the bottom of the mounting support rod and extends through the end where the support column is located along the length of the mounting support rod.

[0013] Furthermore, the longitudinal section of the limiting block is a "T"-shaped structure, and its "T" head is slidably connected to the groove of the mounting support rod.

[0014] Furthermore, auxiliary connecting blocks are provided on both sides of the mounting rod. The auxiliary connecting blocks on each side of the mounting rod are installed between the corresponding stabilizing support rods by mounting screws. The photovoltaic housing plate used to install the photovoltaic panel is installed on the auxiliary connecting blocks.

[0015] Furthermore, a stabilizing support plate is provided on the mounting rod and fixed between the photovoltaic panel and the photovoltaic outer shell. Connecting supports are provided on the top surface of both ends of the mounting rod. The two ends of the stabilizing support plate are detachably connected to the mounting rod through the connecting supports.

[0016] Furthermore, the connecting support includes a first connecting piece and a second connecting piece. The first connecting piece is installed on the top surface of the mounting rod, and the second connecting piece is installed on the bottom surface of the stabilizing plate. The first connecting piece and the second connecting piece are connected by connecting bolts.

[0017] Furthermore, the first connecting piece has an L-shaped structure, and the second connecting piece has a groove-shaped structure.

[0018] Furthermore, the stabilizing column includes a first stabilizing bar and a second stabilizing bar.

[0019] The present invention has the following advantages: the height of the bracket can be adjusted by the sliding cooperation between the first connecting column and the second connecting column; the limiting block rotates at the top of the second connecting column and slides at the lower end of the mounting rod, thereby adjusting the tilt angle of the installed photovoltaic panel; and the angle can be fixed accurately and reliably in multiple positions by the equally spaced positioning grooves and bolt locking, so as to adapt to the light requirements of different seasons and latitudes.

[0020] The structure, consisting of a first stabilizer bar, a second stabilizer bar, and an inclined stabilizing support bar, forms a multi-triangular stabilizing structure with excellent mechanical properties, effectively resisting strong mountain winds.

[0021] The use of L-shaped and groove-shaped connecting plates in conjunction with bolts makes assembly and disassembly easy, greatly simplifying the installation, replacement, and maintenance process of photovoltaic panels and improving work efficiency.

[0022] It is assembled entirely using mechanical parts such as screws, bolts, and sliders, requiring no pneumatic or electric components. Its simple structure and low manufacturing cost, along with the absence of electrical or pneumatic circuit failure risks, make it particularly suitable for long-term use in harsh environments and inconvenient maintenance, such as mountainous areas.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0035] It should be understood that in the description of the embodiments of this utility model, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order. In the embodiments of this utility model, "multiple" refers to two or more.

[0036] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, B existing alone, or both A and B existing simultaneously. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0037] like Figure 1-8 As shown, the angle-adjustable mountain photovoltaic support disclosed in this utility model includes a connecting base plate 1 and a mounting bracket for mounting photovoltaic panels 20. A vertically extending support column is fixed to one end of the connecting base plate 1, and a vertically extending stabilizing column is fixed to the other end. The mounting bracket is supported on the top of the support column and the stabilizing column. The support column includes a first connecting column 4 and a second connecting column 6 axially movably fitted inside the first connecting column 4. The bottom end of the first connecting column 4 is connected to the connecting base plate 1, and the second connecting column 6 is slidably fitted inside the first connecting column 4. That is, the support column formed by the first connecting column 4 and the second connecting column 6 is telescopic. The first connecting column 4 and the second connecting column 6 are connected in a sliding manner. The sliding of the two drives the mounting bracket to rotate around the top of the stabilizing column, thereby adjusting the angle. Figure 3 , Figure 4 and Figure 5 As shown, the second connecting post 6 has multiple positioning grooves 7 along its length extension direction, and the first connecting post 4 has limit holes at the corresponding positions of the positioning grooves 7. The limit bolts pass through the limit holes and selectively cooperate with the positioning grooves 7 at different heights to lock the first connecting post 4 and the second connecting post 6, thus fixing the second connecting post 6 at the required height.

[0038] The bottom end of the stabilizing column is connected to the connecting base plate 1, and the top end of the stabilizing column is rotatably connected to a bearing block 16. The mounting bracket is supported on the bearing block 16. Specifically, the stabilizing column includes a first stabilizing rod 2 and a second stabilizing rod 3. The second stabilizing rod 3 is connected to the top end of the first stabilizing rod 2, and the bearing block 16 is rotatably connected to the top end of the second stabilizing rod 3. Thus, by rotating the bearing block 16 around the top end of the stabilizing column, the mounting bracket supported on the bearing block 16 can rotate around the top end of the stabilizing column, thereby allowing the photovoltaic panel 20 installed on the mounting bracket to rotate around the top end of the stabilizing column, adjusting the installation angle. The stabilizing column adopts a combination design of the first stabilizing rod 2 and the second stabilizing rod 3. The first stabilizing rod 2 is responsible for firmly connecting to the connecting base plate 1, serving as the foundation of the entire structure together with the connecting base plate. The second stabilizing rod 3 is responsible for connecting the upper moving structure with the lower fixed structure and guiding the movement trajectory. Of course, the combination design of multiple rods also facilitates production, transportation, and installation. Shorter rods are easier to handle, and if a part is damaged, it is easier to replace without replacing the entire structure. The top of the stabilizing column is detachably connected to the bearing block 16. The bearing block 16 can be removed as needed. Specifically, the bearing block 16 can be connected to the mounting bracket by screws or other connectors.

[0039] The stabilizing column and the supporting column together provide support for the mounting bracket. To ensure the supporting column provides support while facilitating adjustment of the mounting bracket's tilt angle, a limiting block 8 is rotatably connected to the top of the second connecting column 6. The limiting block 8 connects the second connecting column 6 to the mounting bracket. Unlike the bearing block 16, which is fixed to the mounting bracket with screws or other fasteners, the limiting block 8 is not locked to the mounting bracket. Instead, the bottom of the mounting bracket has a groove 17 that fits the limiting block 8, and the limiting block 8 is movably inserted into the groove 17. It should be noted that the axis of rotation of the bearing block 16 at the top of the stabilizing column is parallel to the axis of rotation of the limiting block 8 at the top of the second connecting column 6, and both are perpendicular to the supporting column and the stabilizing column. If a rectangular coordinate system is established, with its Z-axis parallel to the axis of rotation of the bearing block 16 and its X-axis parallel to the plane containing the axial directions of the supporting column and the stabilizing column, as well as the plane containing the photovoltaic panel 20, then the extension direction of the groove 17 is parallel to the X-axis. Thus, when the height of the support column is adjusted, the limiting block 8 not only rotates but also moves within the slide groove 17 along its extension direction, thereby achieving height adjustment. Throughout the adjustment process, only the height of the support column needs to be adjusted, making the operation simple, easy, and convenient. Furthermore, the entire structure is a mechanical structure, requiring no external power, offering high reliability and low cost, making it ideal for mountainous environments.

[0040] A rubber sealing ring 5 is provided between the top of the first connecting post 4 and the second connecting post 6, and the rubber sealing ring 5 is engaged with the first connecting post 4. The rubber sealing ring 5 can effectively prevent mud, rainwater and dust from entering between the sliding mating surfaces of the first connecting post 4 and the second connecting post 6, reduce wear and corrosion, avoid jamming, significantly extend the service life and maintenance cycle of the bracket, and enhance its adaptability in harsh mountain environments.

[0041] The design of multiple positioning slots 7 provides multiple reliable and repeatable fixed positions, allowing users to easily select the optimal tilt angle based on the season and latitude / longitude. If the spacing between the positioning slots 7 is unequal, it will cause inconvenience in processing. Therefore, in this embodiment, the positioning slots 7 are equally spaced on the second connecting column 6.

[0042] The mounting bracket is mainly used to support the photovoltaic panel 20. It can adopt various structural forms, such as the square frame structure in existing technologies. In this utility model, the mounting bracket includes a mounting support rod 9 and a stabilizing support rod 14. The stabilizing support rod 14 is respectively provided on both sides of the mounting support rod 9. All stabilizing support rods 14 are coplanar, and each stabilizing support rod 14 is inclined to the mounting support rod 9. Mounting screws 15 are installed on the opposite ends of the stabilizing support rods 14 that connect to the mounting support rod 9. Figure 8As shown, the groove is located at the bottom of the mounting rod 9 and extends through the end of the support column along the length of the mounting rod 9. With the mounting rod 9 as the backbone, together with the second connecting column 6, the stabilizing support rod, and the second stabilizing rod, a stable triangular support system is formed. The support system structure is simple, stable, and reliable.

[0043] The longitudinal section of the limiting block 8 is T-shaped, and its T-head is slidably connected to the groove of the mounting rod 9. The T-shaped limiting block 8 and the mounting rod 9 are slidably connected, forming a reliable guiding and limiting mechanism. It ensures that the second connecting column 6) can only move vertically during the sliding process, preventing it from rotating or shaking, making the adjustment process more stable and precise, and also enhancing the structural rigidity and stability of the entire top of the support.

[0044] Furthermore, auxiliary connecting blocks 21 are provided on both sides of the mounting rod 9. The auxiliary connecting blocks 21 on each side of the mounting rod 9 are installed between the corresponding stable support rods 14 by mounting screws 15. The photovoltaic shell plate 19 used to install the photovoltaic panel 20 is installed on the auxiliary connecting blocks 21.

[0045] The stabilizing support rod 14 is inclined, and the opposite end connecting to the mounting rod 9 is a slope, while the mounting surface of the photovoltaic housing panel 19 or photovoltaic panel 20 is usually flat. If a flat panel is directly bolted to the inclined rod end, poor point or line contact will result, leading to an unstable connection, stress concentration, and easy loosening or damage. The auxiliary connecting block 21 changes this situation. One side of it can perfectly fit or connect to the outer end of the inclined stabilizing support rod 14, while the other side provides a horizontal mounting surface for the photovoltaic housing panel 19. This achieves a smooth transition from the inclined rod to the horizontal mounting surface, creating the maximum contact area and making the connection stable and reliable.

[0046] The stabilizing support rod 14 primarily bears the pressure, gravity, and tensile wind loads from the photovoltaic panels. These forces are concentrated at the end of the rod. The auxiliary connecting block 21, as a rigid body, receives the concentrated force from the stabilizing support rod 14 and distributes the force over a larger area of ​​the photovoltaic housing 19 through its larger contact area. This avoids stress concentration, protects the expensive photovoltaic panels and their mounting frames from crushing or tearing, and greatly enhances the safety and durability of the entire support system.

[0047] The auxiliary connecting block 21 tightly connects the stabilizing support rod 14 to the structure above, which can effectively suppress the torsional deformation of the photovoltaic panel and improve the wind resistance of the support.

[0048] A stabilizing support plate 18 is provided on the mounting rod 9 and fixed between the photovoltaic panel 20 and the photovoltaic outer shell panel 19. Connecting supports are provided on the top surfaces of both ends of the mounting rod 9. The two ends of the stabilizing support plate 18 are detachably connected to the mounting rod 9 through the connecting supports.

[0049] The connecting support includes a first connecting piece 10 and a second connecting piece 11, such as Figure 2 , Figure 6 and Figure 7 As shown, the first connecting piece 10 is installed on the top surface of the mounting support rod 9, and the second connecting piece 11 is installed on the bottom surface of the stabilizing support plate 18 by means of threaded nails 13, and the first connecting piece 10 and the second connecting piece 11 are connected by connecting bolts 12.

[0050] The first connecting piece, the second connecting piece, and the photovoltaic outer casing provide the foundation for the rapid installation of photovoltaic panels. This solution features a simple structure, requires no external power source, and boasts high reliability due to its purely mechanical structure, making it ideal for mountainous environments.

[0051] The first connecting piece 10 has an L-shaped structure, and the second connecting piece 11 has a groove-shaped structure, that is, its cross-section is similar to a C-shape. Its top plate is installed on the photovoltaic panel, and its web plate is detachably connected to the first connecting piece 10. Then, by tightening the threaded nail 13, the second connecting piece 11 is connected to the stabilizing support plate 18. Then, by tightening the connecting bolt 12, the first connecting piece 10 and the second connecting piece 11 are connected, thereby installing the photovoltaic panel 20 and the photovoltaic bracket. At the same time, by rotating in the opposite direction to loosen the connecting bolt 12, the first connecting piece 10 and the second connecting piece 11 are separated, and the photovoltaic module can be disassembled, thereby disassembling and replacing the photovoltaic module for easy repair.

[0052] The combined design of the L-shaped first connecting piece 10 and the grooved second connecting piece 11, along with bolt connections, forms an efficient clamping mechanism, enabling modular installation and disassembly of photovoltaic panels. The operation is simple and quick, greatly facilitating on-site maintenance, replacement, and cleaning, and making it easy to disassemble and install photovoltaic modules.

[0053] After the mounting bracket is connected to the mountain, the height of the bracket needs to be adjusted due to the different angles of light. This is achieved by sliding the second connecting column 6 inside the first connecting column 4, while the positioning groove 7 rotates inside the limiting block 8. The limiting block 8 slides at the lower end of the mounting rod 9, and the longitudinal section of the limiting block 8 has a "T" shape, which makes the sliding more stable. This causes the photovoltaic panel 20 to tilt, thereby adjusting the angle. When the adjustment is in the appropriate position, the rotating bolt is turned so that the bolt passes through the appropriate positioning groove 7, thereby limiting the adjustment and increasing the stability after adjustment.

[0054] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
