[0002] During the construction of power transmission lines in mountainous and hilly areas, slope monitoring equipment is typically installed along the line to monitor geological changes in real time, preventing geological disasters such as landslides and collapses from affecting the safety of the lines. Since the monitoring points are mostly located in remote areas lacking municipal power supply, photovoltaic power generation devices are commonly used as independent power supply systems.

[0003] Most existing photovoltaic power supply systems adopt fixed or single-axis adjustable support structures, and the angle of the photovoltaic panels can only be adjusted within a limited range in the pitch direction, without the ability to flexibly adjust the azimuth direction. When the slope orientation or terrain undulation changes, it is difficult for the photovoltaic panels to be aligned with the direction of sunlight, resulting in a decrease in sunlight utilization and a significant reduction in power generation efficiency, which in turn affects the continuous power supply stability of the monitoring equipment.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figure 1 as well as Figure 2 A power supply device for slope monitoring equipment of transmission line engineering based on photovoltaic panels includes an anchoring base 1, a photovoltaic panel assembly 2, a ball joint assembly 3 and a locking collar 4; The ball joint assembly 3 includes a ball joint head 31 and a ball cup seat 32 that are hinged to each other; the ball joint head 31 is fixedly connected to the lower end face of the photovoltaic panel assembly 2, and the ball cup seat 32 is fixedly connected to the anchor base 1. The locking collar 4 is rotatably connected to the outer surface of the spherical bowl seat 32. When the locking collar 4 rotates to the first position, the locking collar 4 is pressed and connected to the spherical bowl seat 32 and used to lock the spherical bowl seat 32 and the spherical joint head 31. When the locking collar 4 rotates to the second position, the locking collar 4 is movably connected to the spherical bowl seat 32 and used to release the spherical bowl seat 32 and the spherical joint head 31.

[0019] As described above, the beneficial effects of this utility model are as follows: The photovoltaic panel assembly 2 and the anchoring base 1 are omnidirectionally connected via the ball joint assembly 3, allowing continuous adjustment of the photovoltaic panel 21 in both pitch and azimuth directions. The locking collar 4 and the spherical cup seat 32, when tightened, generate radial clamping force, enabling stable positioning at any angle. The convertibility of the tightness state allows the photovoltaic panel 21 to flexibly adapt to different terrains and multi-directional incident light conditions, ensuring maximum light utilization in complex slope environments. The anchoring base 1 provides stable support, ensuring the photovoltaic module maintains its posture stability under long-term external forces such as wind load, rain erosion, and temperature differences, thereby improving the continuous power supply reliability of the slope monitoring equipment.

[0020] Please refer to Figure 2 and Figure 3 In some embodiments, the top of the spherical bowl seat 32 is provided with at least two partition openings 321, which divide the spherical bowl seat 32 into a plurality of arc-shaped pressure plates 322; the outer surface of the arc-shaped pressure plate 322 is rotatably connected to the locking collar 4.

[0021] As described above, by setting a partition opening 321 at the top of the spherical bowl seat 32 to form an arc-shaped pressure plate 322, the spherical bowl seat 32 has a radially deformable split structure, which can achieve adaptive deformation during locking or releasing. This structure allows the locking collar 4 to evenly compress each arc-shaped pressure plate 322 when tightened, thereby forming an all-round enveloping clamp on the spherical joint head 31 and improving locking stability; when released, the arc-shaped pressure plate 322 rebounds to create a gap, allowing the photovoltaic panel assembly 2 to smoothly adjust its angle, improving structural durability and adjustment smoothness, avoiding structural damage caused by single-point force, and extending the service life of the ball joint components.

[0022] In some embodiments, each of the arc-shaped pressure plates 322 is provided with a groove 323, and the locking collar 4 is provided with a protrusion that matches the groove 323.

[0023] As described above, a groove 323 is provided on the outer surface of the arc-shaped pressure plate 322, and a protrusion matching the groove 323 is provided on the inner side of the locking collar 4, forming a precise mechanical positioning fit. When the collar rotates, the relative position change between the protrusion and the groove 323 enables a smooth transition from loosening to locking, thus avoiding sudden jamming or uneven wear phenomena in traditional friction locking structures. Furthermore, through the cooperation between the protrusion and the groove 323, the user can intuitively judge the current locking status by the rotation angle, improving the operational safety and maintenance convenience of the device.

[0024] In some embodiments, when the locking collar 4 is rotated to the first position, a portion of the protrusion engages with the groove 323, and another portion presses against the outer surface of the arc-shaped pressure plate 322; when the locking collar 4 is rotated to the second position, the entire protrusion is located in the groove 323.

[0025] As described above, the relative engagement of the protrusion and groove 323 in two positional states achieves a bistable function of locking and releasing. In the first position, the protrusion is embedded in the groove 323 and presses against the outer surface of the arc-shaped pressure plate 322, generating a radial clamping force. In the second position, the protrusion is fully inserted into the groove 323, creating a gap between the ball joint head 31 and the ball cup seat 32, thereby releasing the restriction. By switching between the two stable states, it is ensured that the photovoltaic panel 21 has moderate damping during angle adjustment, high seismic resistance after locking, and can maintain attitude stability under outdoor wind vibration and temperature change environments, avoiding angle drift.

[0026] Please refer to Figure 1 and Figure 4 In some embodiments, the anchoring base 1 includes a base plate 11 and an anchor rod 12, the anchor rod 12 passing through the base plate 11 and being assembled and connected to the base plate 11.

[0027] As described above, the anchoring base 1 consists of a base plate 11 and an anchoring rod 12 penetrating the base plate 11, with a locking nut 16 used for axial clamping. The base plate 11 limits and distributes the force on the anchoring rod 12, forming an effective load transfer path between the surface layer and the underlying soil. Through a detachable assembly method, the embedment depth and direction can be adjusted according to the slope geological conditions during on-site construction, achieving a better stress angle and pull-out resistance. The overall connection maintains stability under long-term loads, preventing overturning due to foundation deformation.

[0028] In some embodiments, the anchoring base 1 further includes a helical blade 13, a mating hole 14, and a pressure-resistant plate 15; the helical blade 13 is circumferentially fixedly connected to the anchor rod 12, the pressure-resistant plate 15 is located above the helical blade 13 and is fixedly connected to the anchor rod 12, and the mating hole 14 is located on the circumferential wall of the anchor rod 12 and is located between the pressure-resistant plate 15 and the base plate 11.

[0029] As described above, the spiral blade 13 creates a cutting and compacting effect when the anchor rod 12 is screwed into the soil, increasing the density of the surrounding soil and thus enhancing the pull-out bearing capacity. The compression plate 15, located above the blade, can disperse stress under axial pressure and prevent local buckling of the rod. The butt hole 14 allows the anchor rod 12 to be quickly connected to the construction equipment, facilitating screwing in or pulling out operations.

[0030] Please refer to Figure 5and Figure 6 In some embodiments, the anchor rod 12 is provided with a locking nut 16 at the top, and the locking nut 16 is provided with a limiting notch 17 at the top; The anchoring base also includes a connecting rod 18, the two ends of which are respectively engaged with the limiting notches 17 of the two anchoring rods 12.

[0031] As described above, the locking nut 16 at the top of the anchor rod 12 is equipped with a limiting notch 17, which forms a lateral connection with adjacent anchor rods 12 via a connecting rod 18. The connecting rod 18 can connect multiple anchor bases 1 of the aforementioned device, and these multiple anchor bases 1 form a spatial constraint frame. After the connecting rod 18 is inserted into the limiting notch 17, it can restrict the relative displacement of the anchor rods 12, forming an integral force-bearing system. When local slippage occurs on the slope, the anchor units can share the external force, reducing the risk of single-point load. Lateral linkage enhances the overall anti-slip and seismic performance, slows the propagation speed of surface slippage, and provides a longer emergency response time for the monitoring system.

[0032] Please refer to Figure 1 In some embodiments, a control box 5 is also included, which is fixedly connected to the photovoltaic assembly and is used to receive the electrical energy generated by the photovoltaic assembly.

[0033] As described above, the control box 5 is fixedly installed with the photovoltaic panel assembly 2, which shortens the power transmission path and reduces the number of external connectors. The photovoltaic current completes energy harvesting and management upon entering the control box 5, avoiding voltage loss and protection risks associated with long-distance transmission. As a power management unit, the control box 5 can directly interface with monitoring equipment, achieving a compact layout. Simultaneously, the centralized arrangement of electrical components facilitates overall encapsulation, improving waterproofing, dustproofing, and electromagnetic interference resistance, ensuring continuous and stable power supply in outdoor environments.

[0034] In some embodiments, the control box 5 includes a charge / discharge controller 51 and a battery 52, the transmission end of the photovoltaic assembly is electrically connected to the charge / discharge controller 51, and the charge / discharge controller 51 is electrically connected to the battery 52.

[0035] As described above, the integrated arrangement of the charge / discharge controller 51 and the battery 52 forms a closed-loop system encompassing photovoltaic power generation, energy storage, and output control. The charge / discharge controller 51 automatically adjusts the charging state through real-time voltage and current monitoring to prevent overcharging or over-discharging, thereby improving battery lifespan. The battery 52, an energy storage unit, provides backup power during periods of insufficient sunlight or at night, maintaining continuous operation of the monitoring equipment. Through intelligent energy management, efficient energy conversion and stable power output are achieved, ensuring the all-weather power supply stability of the slope monitoring system.

[0036] In some embodiments, the photovoltaic panel assembly 2 includes a photovoltaic panel 21 and a backplate frame 22, wherein the photovoltaic panel 21 is fitted and connected to the backplate frame 22, and the lower end face of the backplate frame 22 is fixedly connected to the ball joint head 31.

[0037] As described above, the photovoltaic panel 21 and the backsheet frame 22 are connected by a fitted fixing method. The backsheet frame 22 provides circumferential support and restricts the deformation of the photovoltaic panel 21. The fitted connection can achieve high-strength fixation without adding additional fasteners, reducing vibration stress concentration. The lower end face of the backsheet frame 22 is directly connected to the ball joint head 31, which can maintain the stability of the photovoltaic module's posture when subjected to force transmission, preventing edge warping or glass plate cracking. The surface of the photovoltaic panel 21 receives light uniformly, and the power generation efficiency remains stable, meeting the structural safety and performance reliability requirements in long-term outdoor environments.

[0038] Please refer to Figures 1 to 6 Embodiment 1 of this utility model is as follows: A power supply device for slope monitoring equipment of a power transmission line project based on photovoltaic panels includes an anchoring base 1, a photovoltaic panel assembly 2, a ball joint assembly 3, a locking collar 4, and a control box 5.

[0039] The anchoring base 1 includes a base plate 11 and anchor rods 12. The anchor rods 12 penetrate the base plate 11 and are fixed by locking nuts 16. The base plate 11 serves as a load-bearing and limiting component, bearing the load transfer function of the upper components. The anchor rods 12 are arranged along the normal direction of the base plate 11, with their bottom ends extending below the ground surface to achieve stable fixation of the overall device. Each anchor rod 12 is fixedly provided with a helical blade 13 on its outer periphery. The blades are distributed in a helical pattern along the circumference and are used to cut and compact the surrounding soil during screwing, thereby enhancing the frictional engagement force with the foundation. A pressure-resistant plate 15 is fixed above the helical blades 13. The pressure-resistant plate 15 and the anchor rod 12 form an integral force-bearing surface, used to distribute axial loads and prevent buckling of the rod. The circumferential wall of the anchor rod 12 is provided with a docking hole 14, which can be docked with external mechanical construction equipment to realize operations such as screwing in, pulling out, or angle correction.

[0040] The top of the anchor rod 12 is equipped with a locking nut 16, and multiple limiting notches 17 are opened circumferentially on the nut. Multiple anchor bases 1 are interconnected by connecting rods 18, and the two ends of the connecting rods 18 are respectively inserted into the limiting notches 17 of adjacent anchor rods 12 to form a transverse linkage frame. Multiple anchor units form an overall constraint system in space. When the slope slides or vibrates, each anchor unit can share the stress, realize anti-sliding and anti-seismic effects, thereby delaying the propagation of surface slippage and providing a stable foundation for monitoring equipment.

[0041] The ball joint assembly 3 is installed above the base plate 11 of the anchoring base 1 to connect the photovoltaic panel assembly 2 to the base. The ball joint assembly 3 consists of a spherical joint head 31 and a spherical cup seat 32, with their spherical surfaces matching each other. The spherical joint head 31 is fixedly connected to the lower end face of the photovoltaic panel assembly 2, and the spherical cup seat 32 is fixedly connected to the anchoring base 1, allowing the photovoltaic panel assembly 2 to achieve full-angle rotational adjustment in the pitch and azimuth directions. A locking collar 4 is fitted on the outside of the spherical cup seat 32, and the collar and the outer surface of the spherical cup seat 32 can rotate relative to each other. When the locking collar 4 rotates to the first position, its inner wall forms a radial clamping force on the spherical bowl seat 32, thereby clamping and fixing the spherical joint head 31, and realizing the stable locking of the angle of the photovoltaic panel 21; when the locking collar 4 rotates to the second position, a gap is formed between the inner wall of the collar and the outer surface of the spherical bowl seat 32, allowing the spherical joint head 31 to rotate freely within the spherical bowl seat 32, thereby completing the angle adjustment.

[0042] The top of the spherical bowl seat 32 is provided with multiple partition openings 321, which divide the spherical bowl seat 32 into several arc-shaped pressure plates 322 along the circumference. The outer surface of the arc-shaped pressure plate 322 is in close contact with the inner surface of the locking collar 4. During the locking process, it can undergo slight elastic deformation in the radial direction to achieve uniform compression. When the locking collar 4 is tightened, each arc-shaped pressure plate 322 retracts synchronously, generating a circumferential covering force, so that the spherical joint head 31 is stably fitted in the spherical bowl seat 32. When the locking collar 4 is loosened, the arc-shaped pressure plates 322 rebound, forming a gap, which facilitates the angle adjustment of the photovoltaic panel assembly 2. Each arc-shaped pressure plate 322 has a groove 323 on its outer surface, and the inner wall of the locking collar 4 has a protrusion that matches the groove 323. By changing the relative position of the protrusion and the groove 323, a smooth transition from the released state to the locked state is achieved. In the first position, the protrusion is embedded in the groove 323 and presses against the outer surface of the arc-shaped pressure plate 322, generating a radial clamping force. In the second position, the protrusion is fully inserted into the groove 323, and a gap is formed between the ball joint head 31 and the ball cup seat 32, restoring the adjustable state. Through the cooperation between the protrusion and the groove 323, the locking and releasing process has bistable characteristics, the angle adjustment damping is moderate, the positioning is accurate, and the vibration resistance is strong.

[0043] The photovoltaic panel assembly 2 includes a photovoltaic panel 21 and a backsheet frame 22, with the photovoltaic panel 21 fitted inside the backsheet frame 22. The backsheet frame 22 provides circumferential structural support, limiting the deformation of the photovoltaic panel 21 and preventing warping of the glass panel due to wind vibration or temperature differences. The lower end face of the backsheet frame 22 is fixedly connected to a ball joint head 31, ensuring a continuous and stable force path. Under external wind pressure, the force can be transmitted to the anchor base 1 through the ball joint assembly 3, thereby ensuring the structural stability of the overall device and the accuracy of the light-receiving posture.

[0044] The control box 5 is fixedly installed with the photovoltaic panel assembly 2 and is used to collect and manage the electrical energy output by the photovoltaic panel 21. The control box 5 integrates a charge / discharge controller 51 and a battery 52. ​​The output terminal of the photovoltaic panel 21 is electrically connected to the input terminal of the charge / discharge controller 51, and the output terminal of the charge / discharge controller 51 is electrically connected to the battery 52 for energy storage and release. The control box 5 has a power input interface on its outer wall to provide power to external slope monitoring equipment. The charge / discharge controller 51 monitors the voltage and current status in real time and automatically adjusts the charging process to prevent overcharging or over-discharging. The battery 52 provides backup power during periods of insufficient sunlight or at night to ensure continuous operation of the monitoring equipment. The centralized arrangement of electrical units shortens the transmission path, reduces energy loss, and enhances waterproof and dustproof performance, making it suitable for long-term outdoor working environments.

[0045] When installed on a power transmission line slope, the anchoring base 1 can be mechanically screwed into place. After tightening the locking ring 4, the photovoltaic panel 21 is adjusted to the optimal incident angle according to the slope orientation. After the control box 5 is connected to the monitoring equipment, the system can achieve autonomous power supply and energy dispatch. The entire device maintains stable operation under multi-directional stress environments and can provide continuous power support under long-term outdoor conditions, achieving highly reliable power supply for the slope monitoring equipment.

[0046] Embodiment two of this utility model is as follows: The difference from Embodiment 1 is that the outer surface of the spherical cup seat 32 is provided with external threads, the locking collar 4 is generally conical, the locking collar 4 is provided with internal threads that mate with the outer surface of the spherical cup seat 32, and its upper end is provided with an inwardly contracting conical body. When the locking collar 4 is rotated downward, the conical body will press the arc-shaped pressure plate 322 of the spherical cup seat 32, thereby locking the ball joint assembly 3; when the locking collar 4 is rotated upward, the conical body will release the arc-shaped pressure plate 322 of the spherical cup seat 32, thereby realizing the free rotation of the ball joint assembly 3.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
