Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) take-off and landing platform technology, specifically, it relates to a UAV take-off and landing platform for photovoltaic power station inspection. Background Technology

[0002] Photovoltaic power stations are often built on rooftops, mountains, water surfaces, or deserts. While the sites are open, there are often no permanent take-off and landing facilities, forcing inspection drones to rely on temporary platforms, vehicle roofs, or simple folding tables as landing sites. These temporary solutions are essentially static structures of "flat panels with outriggers." When faced with the narrow-channel winds, thermal pressure winds, and seasonal gusts formed between the photovoltaic arrays, the airflow around the flat panel becomes turbulent, and crosswinds directly impact the drone's landing gear, causing yaw, rollover, or even propeller strikes. Traditional take-off and landing platforms often add counterweights, ground anchors, or raised railings to increase stability. However, counterweights make single-person transport difficult, ground anchors cannot be fixed on rooftops or hardened ground, and raised railings obstruct the drone's downdraft, exacerbating swaying. A more common approach is to use a single-sided windbreak or canvas windbreak. These fixed windbreak structures can only handle a single prevailing wind direction. Once the wind direction changes or a whirlwind appears, turbulence immediately forms on the leeward side, increasing the pressure difference between the front and back of the platform. The drone is "sucked" to one side the moment it takes off or touches down, resulting in a high accident rate. Due to the high frequency of photovoltaic area inspections and the long distances involved, maintenance personnel hope that the platform can be deployed and retracted at will. However, existing products suffer from trade-offs in terms of weight, wind direction adaptability, and structural complexity, failing to meet the needs of rapid relocation and stable flow in multiple wind directions. This has become a prominent shortcoming restricting the efficiency of intelligent photovoltaic inspections. Utility Model Content

[0003] In view of this, the present invention provides a take-off and landing platform for photovoltaic power station inspection drones, which solves the core problems of photovoltaic power station inspection drones being easily affected by crosswinds during take-off and landing in complex and variable crosswind environments, being prone to yaw and rollover, and the inability of traditional fixed windbreak structures to adapt to changes in wind direction in real time, leading to landing failures.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a take-off and landing platform for photovoltaic power station inspection drones, used for the take-off and landing of photovoltaic power station inspection drones, comprising:

[0006] The platform body has a horizontal load-bearing surface;

[0007] Multiple arc-shaped air guide plates are arranged around the outer periphery of the platform body and extend outward and upward along the edge of the platform body;

[0008] A torsion spring hinge connects the lower end of the arc-shaped air guide plate to the edge of the platform body in an elastic manner, so that the arc-shaped air guide plate can swing between the horizontal plane and the inclined plane relative to the platform body.

[0009] When subjected to crosswinds, the arc-shaped wind deflector can automatically adjust its tilt angle under the elastic action of the torsion spring hinge to guide the airflow downward, thereby forming a low-pressure area above the platform body and reducing the interference of crosswinds on the drone.

[0010] The technical effects of the photovoltaic power station inspection drone take-off and landing platform provided by this utility model are as follows: By floating and installing the arc-shaped wind guide plate on the outer periphery of the platform body through the torsion spring hinge, the wind guide plate can be deflected instantly under the action of crosswinds in any direction and guide the airflow downward, forming a relatively low-pressure area above the platform, thereby weakening the lateral thrust and tumbling torque of the crosswind on the drone, realizing pure mechanical adaptive flow stabilization without external power and sensors, and significantly reducing the landing difficulty and overturning risk in complex wind fields.

[0011] Based on the above technical solution, the photovoltaic power station inspection drone take-off and landing platform of this utility model can be further improved as follows:

[0012] The cross-section of the arc-shaped air guide plate is concave arc-shaped, with the concave surface facing the outer side of the platform body to enhance the airflow guiding effect.

[0013] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by using the concave arc-shaped plate surface, the airflow on the windward side is continuously compressed and discharged directionally along the concave surface, which further enhances the low-pressure suction effect, while suppressing airflow separation and vortex vibration, ensuring that the wind guide plate maintains stable and low-noise wind guiding performance under strong gusts.

[0014] Furthermore, the torsion spring hinge includes a hinge shaft and a torsion spring. The torsion spring is sleeved on the hinge shaft, with one end connected to the platform body and the other end connected to the arc-shaped air guide plate, for providing a reset torque.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the torsion spring hinge integrates the hinge shaft and the torsion spring into one piece, which not only provides a reliable rotation center for the air guide plate, but also achieves an instantaneous response of "turning when the wind comes and returning when the wind stops" through the reset torque stored in the torsion spring, avoiding the wear and jamming caused by the use of sliding pairs or gear mechanisms, and requiring no maintenance for a long time.

[0016] Furthermore, the arc-shaped air guide plates are arranged at equal intervals along the circumference of the platform body to form a ring-shaped air guide structure.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the wind deflectors are evenly spaced around the perimeter, so that the platform has symmetrical wind guiding and pressure reduction capabilities in any wind direction, eliminating the wind direction dead angle caused by the traditional single-sided wind deflector, and ensuring that the UAV can obtain a consistent stable flow environment when entering from any direction.

[0018] Furthermore, the upper end of the arc-shaped wind guide plate extends outward at an angle that adaptively adjusts with changes in wind direction and speed.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the upper end of the wind guide plate extending outwards allows it to generate an effective windward area even in the initial light wind, quickly establish deflection torque, and shorten response lag; at the same time, the inclined extension section can also serve as an "airflow extension guide channel", reducing the downwash turbulence formed after the airflow crosses the top of the plate and improving landing stability.

[0020] Furthermore, a gap is provided between the lower end of the arc-shaped wind guide plate and the edge of the platform body to allow the torsion spring hinge to rotate under the action of wind force.

[0021] The platform body has a downward-bent flange on its outer perimeter, with a ring-shaped support plate extending horizontally outward from the lower end of the flange. An "L"-shaped inner flange is welded to or integrally formed on the inner side of the lower end of the arc-shaped air guide plate, and this inner flange is located above and parallel to the ring-shaped support plate. The hinge axis of the torsion spring hinge is vertically fixed to the ring-shaped support plate, allowing the arc-shaped air guide plate to rotate around this axis. A vertical distance H is maintained between the inner flange and the ring-shaped support plate, forming a continuous circumferential gap.

[0022] When the gap is too small (<1mm), sand and dust are easily trapped; when it is too large (>10mm), the air guiding efficiency is reduced and vortex noise is generated. Therefore, the gap is preferably 2-6mm, and more preferably 3-4mm. This range ensures that the air guide plate can swing freely ±30°, and also prevents foreign objects such as gravel and bird droppings from entering the hinged part.

[0023] Furthermore, the platform body is a rigid flat plate structure with downward-facing flanges on its edges to enhance structural strength and provide a mounting base for the torsion spring hinge.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the edge of the main body of the platform is turned down and extended into a ring-shaped support plate, which not only significantly increases the overall torsional stiffness, but also provides a flat and continuous installation reference for the torsion spring hinge, so that the load is evenly transferred to the platform after the air guide plate is subjected to force, avoiding sealing failure caused by local warping or loose bolts.

[0025] Furthermore, the arc-shaped wind guide plate is a thin-walled structure made of lightweight metal or composite material, which has sufficient rigidity to maintain its shape, while also having elasticity to adapt to changes in wind force.

[0026] Examples of materials: 5052-H32 aluminum alloy sheet; AZ31B magnesium alloy sheet; fiber reinforced composite materials: glass fiber / epoxy laminate (G10), or carbon fiber / epoxy prepreg; SUS301-EH stainless steel spring steel strip, for high-wind scenarios requiring higher fatigue life.

[0027] The aforementioned material, with a wall thickness ranging from 0.5 to 1.2 mm, exhibits sufficient bending stiffness. The curved surface remains free from permanent deformation under crosswinds, while the elastic modulus E≤70GPa (aluminum alloy) allows the wind guide plate to generate 2-5mm elastic deflection when impacted by gusts, thereby instantly releasing wind pressure and preventing overload of the torsion spring hinge.

[0028] Furthermore, the torsion spring stiffness of the torsion spring hinge is set such that the arc-shaped wind guide plate can maintain a certain tilt angle under normal wind conditions, and allows further deflection to release wind pressure under strong wind conditions.

[0029] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the torsion spring stiffness is set so that the wind deflector can maintain the optimal wind deflection angle in the normal wind range, while allowing the deflection surface to further deflect to "yield the wind" under sudden strong winds. By increasing the area of ​​the unloading channel, the wind load growth is automatically limited, forming a mechanical "flexible load limiting" effect, which protects the structure from overload damage and prevents the drone from overturning due to sudden crosswinds.

[0030] Furthermore, the arc-shaped wind guide plate is vertical or slightly tilted outward relative to the platform body when stationary, and can deflect outward to a near-horizontal position when exposed to wind, and automatically reset after the wind force weakens.

[0031] The slightly outward tilt state can be understood as follows: when the wind guide plate is still and there is no wind, the upper edge tilts outward by 2° to 3° to a near-vertical state, so as to ensure that the wind direction adaptive mechanism responds immediately and does not affect the reset function.

[0032] Compared with existing technologies, the beneficial effects of the photovoltaic power station inspection drone take-off and landing platform provided by this utility model are as follows: This utility model proposes a wind-direction adaptive wind-guiding take-off and landing platform, integrating the "wind guidance-pressure relief-reset" function into a purely mechanical structure, completely eliminating the dependence on power supply, sensors, and manual adjustment. A ring of torsion spring-hinged arc-shaped wind guide plates is arranged around the outer perimeter of the platform. When there is no wind, the plate surface is close to vertical, hardly increasing the platform's overall dimensions, making it convenient for handling and storage. When a crosswind occurs, each wind guide plate automatically deflects outward under the action of wind pressure, and the concave surface of the plate guides the airflow downward, forming a relatively low-pressure area above the platform. The drone is in a stable flow environment of "upward suction and downward support," and the lateral thrust is significantly weakened. During the deflection process, the torsion spring continuously provides reverse torque. The greater the wind force, the larger the deflection angle, and the wind relief channel expands accordingly. The wind load will not increase indefinitely, achieving a self-protection effect of "flexible load limiting." After the wind force weakens, the torsion spring drives the wind guide plate to slowly reset, and the platform returns to its compact shape, which can be easily loaded into the trunk of a vehicle. Because the wind deflectors are evenly distributed circumferentially, wind from any direction can be intercepted and guided by the nearest panel, eliminating the dead-angle problem of traditional single-sided windbreaks and eliminating the need for on-site orientation adjustments. The entire work cycle requires no locking, plugging, or tightening; maintenance personnel simply place the platform between the photovoltaic channels to immediately perform take-off and landing tasks, significantly shortening relocation time. The platform's weight increase is minimal, making it equally suitable for load-bearing sensitive scenarios such as rooftops and floating pontoons. Both the curved panels and hinges are made of weather-resistant materials, maintaining elasticity and strength even after exposure to salt spray, dust, and UV radiation. They require no lubrication or replacement throughout their lifespan, significantly reducing total life-cycle maintenance costs. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0040] like Figures 1-3 The diagram shown is an example of a take-off and landing platform for a photovoltaic power station inspection drone provided by this utility model, used for the take-off and landing of a photovoltaic power station inspection drone, comprising:

[0041] Platform body 10, platform body 10 has a horizontal bearing surface 11;

[0042] Multiple arc-shaped air guide plates 20 are arranged around the outer periphery of the platform body 10 and extend outward and upward along the edge of the platform body 10;

[0043] A torsion spring hinge connects the lower end of the arc-shaped air guide plate 20 to the edge of the platform body 10 elastically, allowing the arc-shaped air guide plate 20 to swing between the horizontal and inclined planes relative to the platform body 10.

[0044] When subjected to crosswinds, the arc-shaped wind deflector 20 can automatically adjust its tilt angle under the elastic action of the torsion spring hinge to guide the airflow downward, thereby forming a low-pressure area above the platform body 10 and reducing the interference of crosswinds on the UAV.

[0045] In the above technical solution, the cross-section of the arc-shaped air guide plate 20 is concave arc-shaped, with the concave surface facing the outside of the platform body 10, in order to enhance the airflow guiding effect.

[0046] Furthermore, in the above technical solution, the torsion spring hinge includes a hinge shaft and a torsion spring. The torsion spring is sleeved on the hinge shaft, with one end connected to the platform body 10 and the other end connected to the arc-shaped air guide plate 20, for providing a reset torque.

[0047] Furthermore, in the above technical solution, the arc-shaped air guide plates 20 are arranged at equal intervals along the circumference of the platform body 10 to form a ring-shaped air guide structure.

[0048] Furthermore, in the above technical solution, the upper end of the arc-shaped wind guide plate 20 extends outward at an angle that adaptively adjusts with changes in wind direction and wind speed.

[0049] Furthermore, in the above technical solution, a gap is provided between the lower end of the arc-shaped wind guide plate 20 and the edge of the platform body 10 to allow the torsion spring hinge to rotate under the action of wind force.

[0050] Furthermore, in the above technical solution, the platform body 10 is a rigid flat plate structure with downward flanges on its edges to enhance structural strength and provide a mounting base for the torsion spring hinge.

[0051] Furthermore, in the above technical solution, the arc-shaped wind guide plate 20 is a thin-walled structure made of lightweight metal or composite material, which has sufficient rigidity to maintain its shape, while also having elasticity to adapt to changes in wind force.

[0052] Furthermore, in the above technical solution, the torsion spring stiffness of the torsion spring hinge is set such that the arc-shaped wind guide plate 20 can maintain a certain tilt angle under normal wind conditions, and can be further deflected to release wind pressure under strong wind conditions.

[0053] Torsional spring stiffness represents the torque required per unit angular displacement. Preset normal wind operating range: average wind speed at a height of 10m above ground. Corresponding wind pressure ;

[0054] Preset strong wind unloading zone: gusts Corresponding wind pressure ;

[0055] Calculate wind load torque: A represents the projected area of ​​the wind guide plate. θ is the distance from the center of wind pressure to the hinge axis, and θ is the angle between the plate surface and the vertical plane.

[0056] Select initial angle (Maintaining tilt angle under normal wind conditions) requires Solving for ;

[0057] Checking the limiting angle If the value exceeds the limit, k can be reduced by increasing the effective number of turns n or decreasing the wire diameter d to ensure that the plate can continue to deflect and relieve pressure during strong winds.

[0058] The material example is 65Mn spring steel wire, with a diameter of... Mean diameter D = 12-18mm, effective number of turns n = 8-15 turns, surface electrophoretic corrosion protection.

[0059] Furthermore, in the above technical solution, the arc-shaped wind guide plate 20 is vertical or slightly tilted outward relative to the platform body 10 when stationary, and can deflect outward to a near-horizontal position when exposed to wind, and automatically reset after the wind force weakens.

[0060] Specific Implementation Example 1: In an inland mountain photovoltaic power station, the photovoltaic strings are arranged in a staggered pattern along the ridge, with the wind direction influenced by the valley and alternating between day and night. The main body of the platform is made of rectangular aluminum alloy checkered plate, with four arc-shaped wind guide plates on each of the two outer sides of the long side. The height of the plate is approximately six times the thickness of the platform, and the concave radius matches the length of the plate. The lower end of the arc-shaped wind guide plate is folded out into a horizontal inward folded edge, and a hinge seat is welded to the outer edge of the platform. The hinge shaft passes vertically through a torsion spring and is fixed to the seat wall. One end of the torsion spring is inserted into the bottom of the seat, and the other end abuts against the inward folded edge. The pre-tightening angle causes the plate surface to tilt outward by about two degrees when there is no wind.

[0061] In use, maintenance personnel transport the platform to the gaps in the array using a folding trolley, and unfold the support legs to complete the deployment. When mountain winds come from the side, the two curved air guides on the windward side first open outward under the force, and the concave surface guides the airflow diagonally downward, forming a low-pressure area above the platform; the leeward side plate slightly contracts inward due to negative pressure, similarly guiding the wake downward and preventing vortices from rising. During the drone's descent, the downwash airflow from the rotor blades overlaps with the downward-deflected airflow from the air guides, providing the drone with additional downward airflow buffer and reducing roll. After the gusts pass, the torsion springs synchronously reset the plates, and the platform returns to its compact shape, ready to be pushed to the next array for continued operation. Throughout the process, no orientation adjustment, external power supply, or ground anchor is required, making it suitable for ridge passages with slopes of less than ten degrees and narrow maintenance access roads.

[0062] Specific Implementation Example 2: The coastal tidal flat photovoltaic power station uses a pipe pile support structure. The modules are located high off the ground, on a soft beach with heavy salt spray, and experience frequent day-night transitions between sea and land breezes. The main body of the platform is a square carbon fiber sandwich panel, with detachable floating boxes fitted at the four corners to ensure stable floating during high tide. Five arc-shaped wind guide plates are arranged on each side, made of 0.8 mm thick 5052 aluminum alloy, with anodized and then coated with a ceramic coating to improve salt spray resistance. The torsion spring hinge uses a stainless steel hinge shaft and a double-layer parallel torsion spring structure. The double-layer torsion springs are wound in opposite directions, increasing stiffness while reducing wire diameter for the same installation length, thus reducing the risk of corrosion.

[0063] During deployment, the maintenance vessel tows the platform to the gap between the piles, and the pontoon is lowered, automatically leveling it. After low tide, the pontoon rests on the beach, while the platform remains level. When the sea wind suddenly changes direction, the curved wind deflectors on either side open outward under wind pressure, and double-layer torsion springs provide rebound force to ensure that the deflectors do not overturn excessively under strong gusts. The airflow folded down by the curved deflectors is reflected by the water layer on the beach, forming a secondary boundary layer, which further weakens the lateral eddies. After the UAV completes its inspection and takes off, the wind deflectors quickly return to their original position under the action of the torsion springs, and the platform can be towed to the next sub-array. This embodiment is suitable for coastal or surface photovoltaic fields with large tidal ranges, low foundation bearing capacity, and high-frequency wind direction changes, while meeting the requirements of rapid relocation and maintenance-free operation.

[0064] Specifically, the principle of this invention is as follows: the core of the platform's flow stabilization lies in the adaptive aerodynamic boundary formed by the arc-shaped plate, torsion spring, and hinge shaft. The concave surface of the arc-shaped plate is equivalent to a miniature guide vane with a fixed curvature. When the airflow impacts the plate surface, the flow velocity decreases and the pressure increases on the concave side, while the flow velocity increases and the pressure decreases on the convex side. This pressure difference pushes the plate surface to rotate outward around the hinge shaft. Simultaneously, the rotation compresses the torsion spring, and the torsion spring torque and the wind pressure torque reach a new equilibrium, causing the plate surface to stop at a certain deflection angle. At this time, the airflow is forced downward, and the kinetic energy is converted into downward momentum, which is equivalent to forming a "flexible wind curtain" around the platform. The upstream wind curtain blocks the external lateral flow, and the downstream wind curtain guides the residual turbulence away from the UAV, naturally creating a low-pressure stable flow zone at the center of the platform. Because the plate surface deflection angle automatically increases or decreases with the wind pressure, the unloading channel area increases synchronously with the wind load, and the maximum bending moment on the platform is limited to the material's allowable range, avoiding the linear deterioration phenomenon of "the stronger the wind, the higher the load" seen in traditional rigid windbreaks. When the gust of wind passes, the torsion spring releases its stored elastic potential energy, and the plate returns to its initial position at a constant speed, awaiting the next change in wind direction. The entire adjustment process relies solely on the real-time interplay between wind pressure and spring force, requiring no external energy input and eliminating the risk of electronic component failure. By changing the radius of curvature of the curved plate, the stiffness of the torsion spring, and the height of the hinge point, wind speed distributions in different regions can be matched during the design phase, achieving customized "one parameter per location," while the on-site usage steps remain unchanged—stable upon deployment and ready to take off immediately, enabling photovoltaic power station inspection drones to obtain consistent, reliable, and repeatable take-off and landing conditions in complex wind environments.
