Description

Technical Field

[0001] This invention relates to the field of drone nest technology, and in particular to a large-stroke photovoltaic nest top cover opening and closing mechanism and the nest thereof. Background Technology

[0002] With the widespread adoption and in-depth application of drone technology in various fields such as logistics delivery, power line inspection, and environmental monitoring, the industry has put forward increasingly stringent requirements for the intelligence level, multi-task carrying capacity, green energy-saving performance, and adaptability to complex environments of drone landing pads.

[0003] However, most drone hangars on the market are currently single- or dual-drone positions, and their top cover opening and closing mechanisms typically use conventional drawer-type rails. Due to limitations in the material properties and structural design of the rails, when the top cover opening and closing stroke exceeds 1.5 meters, the load-bearing capacity of the rails decreases sharply, easily leading to malfunctions such as rail bending and slippage, thus affecting the normal use of the helipad. Furthermore, the short-stroke top cover opening and closing mechanism restricts the deployment of multiple drone positions within a single hangar, resulting in poor adaptability to multi-drone collaborative operation scenarios and difficulty in meeting the needs of batch operations. Therefore, it is evident that the existing drone helipads are no longer adequately designed in terms of structure and function to meet the current development needs of the industry. Summary of the Invention

[0004] This invention proposes a large-stroke photovoltaic (PV) housing top cover opening and closing mechanism and the housing itself, to overcome the shortcomings of the prior art. This mechanism enables the housing top cover to have a large-stroke, stable opening and closing capability, allowing the housing to support multiple drone positions and meeting the needs of batch PV operations. The technical solution of this invention is: a large-stroke photovoltaic cell top cover opening and closing mechanism for slidingly opening and closing two top covers on the cell body, wherein the top covers have longitudinal connecting edges on both sides in the sliding direction, characterized in that the opening and closing mechanism includes: The load-bearing angle steel support beam is L-shaped and is located on the inner side of the connecting edge on the top cover. The load-bearing angle steel support beam has a first part and a second part that are perpendicular to each other. The first sliding member includes a first slider disposed on the first part of the load-bearing angle steel support beam and a first guide rail disposed on the second part. The length of the first guide rail is greater than the length of the top cover. The first guide rail extends out from the opposite side of the two top covers, and the two opposite first guide rails are staggered vertically. The second sliding member includes a second guide rail disposed at the top of the nest and a second slider disposed on the outer wall of the nest. The first slider is slidably connected to the second guide rail, and the second slider is slidably connected to the first guide rail. The drive unit is located on the nest body and is used to drive the top cover to slide.

[0005] In at least one embodiment of the present invention, the driving component includes: a rack and a servo motor, the rack being disposed on the first part of the load-bearing angle steel support beam; the servo motor being disposed on the inner side wall of the nest, a reducer being connected to the output shaft of the servo motor, and a gear meshing with the rack being disposed on the output shaft of the reducer.

[0006] In at least one embodiment of the present invention, a proximity switch is provided on the inner sidewall of the nest along its length, and a sensing plate opposite to the proximity switch is provided on the load-bearing angle steel support beam.

[0007] In at least one embodiment of the present invention, there are multiple first sliders and second sliders, and each of the first sliders and second sliders is provided with a T-shaped groove. The first sliders and second sliders are respectively mounted on the first guide rail and the second guide rail.

[0008] The present invention also proposes a solar cell, including the above-mentioned large-stroke solar cell top cover opening and closing mechanism, wherein the cell body is provided with multiple landing pads along its length.

[0009] In at least one embodiment of the present invention, the top cover is provided with an RTK locator.

[0010] In at least one embodiment of the present invention, a photovoltaic panel is provided on the top cover, a drag chain bracket is horizontally arranged on the inner side wall of the nest, a connecting frame is provided on the top cover, a drag chain connected to the connecting frame is provided on the drag chain bracket, and the cable of the photovoltaic panel passes through the drag chain.

[0011] Compared with the prior art, the beneficial effects of the present invention are: The large-stroke photovoltaic cell top cover opening and closing mechanism proposed in this invention features an L-shaped load-bearing angle steel support beam located on the inner side of the top cover connecting edge. A first slider and a first guide rail are respectively arranged in the first and second perpendicular parts of the beam. Simultaneously, a second guide rail and a second slider are correspondingly arranged on the top and outer wall of the cell, allowing the first slider and second guide rail to slide together, forming a double-sided, double-dimensional composite sliding support structure. Furthermore, because the length of the first guide rail is greater than the length of the top cover and extends from opposite sides of the two top covers, and the two opposing first guide rails are staggered vertically, even after the top cover is fully opened, the first guide rail can still maintain effective sliding support with the second slider over a large stroke, preventing the guide rail ends from being suspended or unevenly loaded. The staggered design also eliminates spatial interference between the first guide rails during the opening process of the two top covers, further improving the stability of movement and structural safety under extreme stroke conditions. The above structure transforms the load-bearing capacity during the opening and closing of the top cover from the conventional unidirectional guide rail force to a multi-directional distributed transmission between the angle steel support beam, the slider and the guide rail. This significantly improves the structural rigidity and load-bearing stability during the large stroke sliding process, effectively avoids guide rail bending and sliding jamming, and thus achieves stable opening and closing with a large stroke of ≥2m, providing a reliable motion foundation for the layout of multiple machine positions inside the machine nest.

[0014] The accompanying drawings in this invention are not strictly drawn to scale, and the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this invention are merely structural schematic diagrams.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "inner," "outer," "upper," "lower," "far," "near," "front," and "rear" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0017] However, current drone helipads on the market still have many technical shortcomings, making them difficult to adapt to large-scale, automated operation scenarios: First, the design of the helipads is relatively simple, mostly single or dual-position, which is not well adapted to scenarios where multiple drones work together, and cannot meet the needs of batch operations; Second, the structural design has limitations. Most helipads use conventional drawer-type guide rails to open and close the top cover. Due to the limitations of the guide rail material and structural design, when the opening and closing stroke of the top cover exceeds 1.5m, the load-bearing capacity of the guide rail will decrease sharply, and faults such as guide rail bending and sliding jamming are prone to occur, affecting the normal use of the helipad.

[0018] In summary, the existing structure and function design of drone landing pads can no longer meet the needs of industry development. Developing an intelligent landing pad with multi-position support, long-stroke stable opening and closing, and high-precision guidance has become a key technical problem that urgently needs to be solved in the current field of drone applications.

[0019] Combination Figures 1 to 6 As shown, a large-stroke photovoltaic cell top cover opening and closing mechanism is used to slide open and close two top covers 2 on the cell body 1. The top covers 2 have longitudinal connecting edges on both sides in the sliding direction. The opening and closing mechanism is characterized by comprising: The load-bearing angle steel support beam 3 is L-shaped and is set on the inner side of the connecting edge on the top cover 2. The load-bearing angle steel support beam 3 has a first part and a second part that are perpendicular to each other.

[0020] The first sliding component includes a first slider 4 set on the first part of the load-bearing angle steel support beam 3 and a first guide rail 5 set on the second part. The length of the first guide rail 5 is greater than the length of the top cover 2. The first guide rail 5 extends out from the opposite side of the two top covers 2, and the two opposite first guide rails 5 are staggered vertically. The purpose of the above design is to reduce the local load-bearing capacity of the top cover 2 after it is fully opened.

[0021] The second sliding component includes a second guide rail 6 disposed on the top of the nest body 1 and a second slider 7 disposed on the outer wall of the nest body 1. The first slider 4 is slidably connected to the second guide rail 6, and the second slider 7 is slidably connected to the first guide rail 5. The first guide rail 5 and the second guide rail 6 are industrial-grade linear guide rails: mechanical transmission components with high load-bearing capacity and high-precision guiding function. Compared with conventional drawer-type guide rails, they can achieve stable sliding with a larger stroke (≥2m). The driving component 8 is installed on the nest body 1 and is used to drive the top cover 2 to slide. The above structure transforms the load-bearing capacity of the top cover 2 during opening and closing from the conventional unidirectional guide rail force to the multi-directional distributed transmission between the angle steel support beam 3, the slider and the guide rail. This significantly improves the structural rigidity and load-bearing stability during the large stroke sliding process, effectively avoids guide rail bending and sliding jamming, and thus achieves stable opening and closing of a large stroke of ≥2m, providing a reliable motion basis for the layout of multiple machine positions inside the nest.

[0022] As an alternative embodiment, the drive component 8 includes a rack 81 and a servo motor 82. The rack 81 is mounted on the first part of the load-bearing angle steel support beam 3. The servo motor 82 is mounted on the inner wall of the nest body 1. A reducer 821 is connected to the output shaft of the servo motor 82, and a gear 822 meshing with the rack is mounted on the output shaft of the reducer 821. In specific operation, when the top cover 2 is opened, the front and rear servo motors 82 receive a command and start the motors simultaneously. Through the reduction transmission of the reducer 821, the gear 822 drives the rack 81 and the load-bearing angle steel support beam 3, together with the top cover 2 above, to move outward until it is opened to the maximum opening position. When the top cover 2 is closed, the servo motors 82 receive a command and start the motors simultaneously, driving the rack 81 to move inward with the front and rear load-bearing angle steel support beams 3, together with the top cover 2 above, until the left and right photovoltaic tops are closed. Cover 2 is fully closed; as another possible method for the drive component 8, the transmission method of gear 822 and rack 81 can be replaced by synchronous belt-synchronous pulley transmission. The synchronous belt is made of polyurethane material (steel wire core), and the module of the synchronous pulley matches that of the synchronous belt. It can also achieve stable opening and closing with a large stroke, and the transmission noise is lower. However, the positioning accuracy and load-bearing capacity of rack-gear transmission are better, making it suitable for scenarios with high precision requirements. Furthermore, the first guide rail 5 and the second guide rail 6 both use industrial-grade linear guide rails instead of conventional drawer-type guide rails. With rack 81-gear 822 transmission, the opening and closing stroke is increased from ≤1.5m to ≥2m, and the load-bearing capacity is increased from ≤50kg / m to ≥100kg / m. It can support heavier photovoltaic panels 22 and equipment, and the sliding stability is higher, avoiding jamming and deformation under large stroke.

[0023] As an alternative embodiment, a proximity switch 9 is provided on the inner sidewall along the length of the housing 1, and an induction plate 91 opposite to the proximity switch 9 is provided on the load-bearing angle steel support beam 3. The proximity switch 9 and the induction plate 91 together constitute the position detection and limit control component for the opening and closing stroke of the top cover 2. Its core function is: when the photovoltaic top cover 2 moves to the preset maximum open position or fully closed position under the drive of the servo motor 82, the induction plate 91 installed on the load-bearing angle steel 3 will move accordingly and trigger the proximity switch 9 installed at the corresponding position on the housing 1, thereby sending a positioning signal to the control system to control the motor to stop running or change the direction of movement. This mechanism ensures the precise control and safe limit of the opening and closing stroke of the top cover 2, avoiding structural collisions, guide rail damage, or motor overload caused by overtravel operation, and is an important guarantee for realizing the large-stroke automatic opening and closing function.

[0024] As an alternative embodiment, multiple first sliders 4 and second sliders 7 are provided, and T-slots are provided on both first sliders 4 and second sliders 7. The first sliders 4 and second sliders 7 are respectively mounted on the first guide rail 5 and the second guide rail 6. By providing T-slots on the first sliders 4 and second sliders 7 and respectively mounting them on the first guide rail 5 and the second guide rail 6, a mechanical interlocking sliding fit is formed between the T-slots and the guide rails. This effectively prevents the sliders from derailing or laterally swaying during sliding, significantly improving the sliding stability and resistance to lateral loads of the top cover 2 during large-stroke opening and closing, while ensuring the fitting accuracy and reliability of the first slider and the second slider in long-term reciprocating motion.

[0025] The present invention also proposes a drone nest, including the above-mentioned large-stroke photovoltaic drone nest top cover opening and closing mechanism. The nest body 1 is provided with multiple landing pads 11 along its length direction. Preferably, three landing pads 11 are provided along its length direction. Compared with the existing dual-position landing pads, the number of positions is increased by 50%, which can meet the docking and maintenance needs of 3 drones at the same time, greatly improving the operation efficiency. It is especially suitable for multi-drone collaborative operation scenarios such as logistics distribution and cluster inspection.

[0026] As an alternative embodiment, the top cover 2 is equipped with an RTK locator 21. The main function of the RTK locator 21 is positioning, which can control the landing error of the aircraft within ±5cm. The RTK locator 21 can be replaced by a "visual guidance module", which uses a high-definition camera to collect images of the drone and combines them with image recognition algorithms for positioning guidance. It can also achieve accurate docking and is not limited by lighting conditions. It is suitable for indoor or low-light environments, but the RTK guidance has a faster response speed and better stability in outdoor strong light environments. As an alternative embodiment, the top cover 2 is also equipped with an image transmission antenna 25, an ultrasonic sensor 26, and a camera 27. Specifically, the image transmission antenna 25 is mainly used to receive images and other data transmitted back during the drone's mission. The ultrasonic sensor 26 is used to monitor real-time weather conditions, such as temperature, wind direction, wind force, and humidity, in order to determine whether to take off and to obtain environmental information. The camera 27 is used to monitor information such as drone landing and can also monitor the external situation of the drone nest in real time. Installing them on the top of the drone nest can maximize their functionality, prevent interference from other devices, and improve their integration (traditionally, they are usually installed on separate brackets at a high place near the drone nest).

[0027] As an alternative embodiment, the top cover 2 is equipped with a photovoltaic panel 22, a drag chain bracket 12 is horizontally arranged on the inner side wall of the nest 1, the top cover 2 is equipped with a connecting frame 23, and the drag chain bracket 12 is equipped with a drag chain 24 connected to the connecting frame 23. The cable of the photovoltaic panel 22 passes through the drag chain 24. The integration of photovoltaic modules enables the helipad to get rid of dependence on the external power grid and can be used normally in remote areas, field operations and other areas without power grid coverage. Moreover, solar energy, as a renewable energy source, is in line with the trend of green energy development and reduces the cost of use.

[0028] As an alternative embodiment, a warning light strip is provided on the outer wall of the connecting edge 21 on the top cover 2. When the top cover of the machine nest is opened, the warning light strip flashes to serve as a warning to prevent personnel from getting close and being accidentally injured. The operating status of the machine nest equipment can also be judged by the color of the warning light.

[0029] The above embodiments are merely specific implementations of the present invention, used to illustrate the technical solutions of the present invention, and not to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed in the present invention, or make equivalent substitutions for some of the technical features; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions implemented in the present invention, and should all be covered within the protection scope of the present invention.
