Description
Technical Field
[0001] This utility model relates to a rainproof device for a vertical take-off and landing aircraft platform, belonging to the field of platform rainproof technology. Background Technology
[0002] As traffic congestion in major cities worsens, the demand for air cargo transport and air travel is becoming increasingly urgent, giving rise to the low-altitude economy. The low-altitude economy refers to low-altitude flight activities within low-altitude airspace, centered on civilian manned and unmanned aerial vehicles, encompassing passenger transport, cargo transport, and other operations. With the rapid development of the low-altitude economy, short-haul helicopter travel has become increasingly common, and the use of drones for express delivery, medical supply transport, and other cargo pickup and delivery services has become more convenient and efficient. For this new mode of low-altitude economic transportation, the construction of facilities capable of accommodating the take-off, landing, and parking of small manned helicopters and drones with vertical take-off and landing capabilities is an indispensable infrastructure guarantee for meeting the needs of low-altitude flight.
[0003] Currently, the infrastructure for the low-altitude economy includes ground helipads and rooftop parking platforms. Helicopters or drones can be parked on ground helipads or rooftop platforms. On ground helipads, each aircraft is laid flat, occupying a large space and requiring a large area of land, which is especially difficult to achieve in many cities with limited land. In existing cities, there are many tall buildings, and currently, most aircraft are parked on rooftop platforms. However, these platforms are usually open-air, and aircraft stored in the open are exposed to wind and sun, which can affect their lifespan over time.
[0004] As a platform specifically designed for vertical takeoff and landing (VTOL) aircraft, the aircraft takes off and lands on the top-floor platform. When not in use, the VTOL aircraft can be moved to the next floor for storage or maintenance via an elevator, essentially parking it inside the building. In this case, the atrium on the top floor used for the elevator needs a rainproof cover. Installing a conventional roller shutter is one solution, but it has the following drawbacks: firstly, the roller shutter device is relatively bulky, slow to operate, and energy-intensive; secondly, existing roller shutters use aluminum alloy panels, which do not provide true rain protection. Furthermore, due to the height restrictions around the aircraft's elevator platform, the large size of the roller shutter makes installation inconvenient. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a rainproof device for vertical take-off and landing aircraft platforms.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rainproof device for a vertical take-off and landing aircraft platform, the platform including a platform body and a skylight provided on the platform body, the rainproof device including a telescopic roller shutter, a roller shutter tube and guide rails provided on the left and right sides of the telescopic roller shutter, the telescopic roller shutter including multiple roller shutter beams arranged in parallel, the roller shutter beams being provided with a rainproof cloth, the two ends of the roller shutter beams being respectively provided with sliders that can slide on the guide rails, and also including a pull-out drive mechanism; The pull-out drive mechanism includes a pair of driving wheels located at the front end of the guide rail and a pair of driven wheels located at the rear end of the guide rail. The driving wheels and driven wheels are connected by an annular transmission belt. A pull-out motor is provided on the outside of the driving wheels. The pull-out motor is connected to the wheel axle of the driving wheels through a pull-out clutch. The annular conveyor belt is located outside the slider, and the roller blind beam includes a tail beam, with both ends of the tail beam extending outward and connecting to the annular conveyor belt.
[0007] The beneficial effects of this utility model are as follows: Compared with conventional roller shutters, the rainproof device of this platform ensures the waterproof function of the retractable roller shutter through the cooperation between the rainproof cloth and the roller shutter crossbeam. The cooperation between the pull-out drive mechanism and the tail beam makes it more convenient and faster to unfold the retractable roller shutter to cover the atrium. The retractable roller shutter has a lightweight structure, is easy to drive, and consumes little energy, solving the problems of heavy, slow-drive, and energy-intensive roller shutters. Because a rainproof cloth is used as the roller shutter, the size of the roller shutter tube can be greatly reduced, thus reducing the volume of the components used to store the roller shutter tube. The pull-out motor and the drive wheel are coaxially arranged, reducing the height space occupied by the motor compared to a vertically installed motor. This meets the aircraft's height restrictions around the platform body, solving the problem of inconvenient installation due to height restrictions around the aircraft's lifting platform, and improving the convenience and reliability of the rainproof device.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, both the driving wheel and the driven wheel are sprockets, and the annular transmission belt is a chain.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the sprocket and chain transmission has the advantages of high transmission accuracy and strong load-bearing capacity. During the operation of the rainproof device on the vertical take-off and landing aircraft platform, it can ensure stable power transmission between the driving wheel and the driven wheel, making the roll-up curtain unfolding action more accurate and avoiding problems such as curtain jamming caused by transmission errors. The overall operation of the rainproof device is stable and reliable.
[0011] Furthermore, both the driving wheel and the driven wheel are synchronous wheels, and the annular transmission belt is a synchronous belt.
[0012] The beneficial effects of adopting the above-mentioned further solution are that during the operation of the rainproof device of the vertical take-off and landing aircraft platform, the synchronous pulley and synchronous belt cooperate to drive smoothly, which can meet the stable deployment requirements of the telescopic roller shutter, with low noise and low maintenance cost.
[0013] Furthermore, the rainproof cloth is a non-woven fabric or a plastic film.
[0014] The advantages of adopting the above-mentioned further solutions are that non-woven fabric is lightweight, yet possesses a certain degree of strength and durability, enabling it to reduce the impact on the overall weight of the aircraft platform while providing rain protection. Its softness also makes the roll-up shutter's unfolding and retraction smoother and less prone to damage. Plastic film, on the other hand, has excellent waterproof performance and good flexibility, effectively blocking rainwater penetration. It can closely conform to the shape of the roll-up shutter, and its relatively low cost and ease of replacement further enhance the practicality and economy of the rainproof device.
[0015] Furthermore, it also includes a roller shutter box, in which the roller shutter is rotatably installed. The roller shutter rotates under the action of a roller shutter drive mechanism, which includes a roller shutter motor connected to the roller shutter via a roller shutter clutch.
[0016] The beneficial effect of adopting the above-mentioned further solution is that the roller shutter box provides storage space for the roller shutter tube, effectively protecting the roller shutter tube and its drive components from interference and damage from the external environment. The roller shutter motor, as the power source, is connected to the roller shutter tube via a roller shutter clutch. When the roller shutter tube needs to be retracted, the roller shutter clutch connects the roller shutter motor to the roller shutter tube's shaft, realizing power transmission to the roller shutter tube. The roller shutter motor operates, and the roller shutter tube's shaft rotates to complete the retraction of the retractable roller shutter. When the roller shutter needs to be unfolded, the roller shutter clutch disconnects the roller shutter motor from the roller shutter tube's shaft, and the pull-out clutch connects the pull-out motor to the drive wheel. The pull-out motor operates, and the annular conveyor belt drives the tail beam to move towards the tail end of the guide rail, thereby unfolding the retractable roller shutter. This allows the retractable roller shutter to cover the atrium, protecting it from or even reducing the entry of rainwater.
[0017] Furthermore, it also includes an electronic control system, which includes a controller and an angle encoder. The angle encoder is mounted on the pull-out motor, and the controller is used to receive signals from the angle encoder and control the operation of the pull-out clutch, the pull-out motor, the drum clutch, and the drum motor.
[0018] The beneficial effect of adopting the above-mentioned further solution is that, by setting up an electronic control system, the pull-out clutch, pull-out motor, drum clutch, and drum motor can be precisely controlled to operate according to a program, realizing the automated operation of the retractable roller shutter's unfolding and retraction. Angle encoders can provide real-time feedback on the rotation angle information of the pull-out motors on both sides of the guide rail. The controller precisely controls the movement of the pull-out motors on both sides based on these signals, ensuring that the retractable roller shutter can be accurately unfolded to the required position. This greatly improves the operational accuracy and reliability of the rainproof device, further enhancing the vertical take-off and landing aircraft platform's protective capabilities in rainy weather. Furthermore, the upper surface of the roller shutter box is flush with the guide rail, and the height difference between the guide rail and the platform body is less than 200mm.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the roller shutter box is suspended on the platform body, its upper plane is level with the guide rail, and the height difference between the guide rail and the platform body is less than 200mm. Considering that the vertical take-off and landing aircraft does not allow any buildings higher than 250mm above the platform body within a distance of at least three meters around the platform body, the height space occupied by the roller shutter box and guide rail on the platform body is reduced, thus avoiding interference with the take-off and landing of the vertical take-off and landing aircraft.
[0020] Furthermore, the roller blind beam includes an upper beam and a lower beam, and the rainproof cloth is held between the upper beam and the lower beam.
[0021] The beneficial effect of adopting the above-mentioned further solution is that it makes the crossbeam support stronger, which can achieve stable support for the rainproof cloth, ensure the reliability of the deployment and storage of the rainproof device, and thus better protect the vertical take-off and landing aircraft platform.
[0022] Furthermore, the annular conveyor belt includes a conveying section and a return section located below the conveying section, and the two ends of the tail beam are respectively connected to the return section.
[0023] The beneficial effect of adopting the above-mentioned further solution is that by connecting the tail beam to the return section of the circular conveyor belt, the position of the telescopic roller shutter is lowered as much as possible, so that the telescopic roller shutter is located at the lower part of the guide rail, and the unfolding and retraction of the telescopic roller shutter is more stable.

[0025] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0026] like Figures 1-10 As shown, a rainproof device for a vertical take-off and landing aircraft platform is provided. The platform includes a platform body 1 and a skylight provided on the platform body 1. The rainproof device includes a telescopic roller shutter, a roller shutter tube 5, and guide rails 4 provided on the left and right sides of the telescopic roller shutter. The telescopic roller shutter includes multiple roller shutter beams 2 arranged in parallel. A rainproof cloth 3 is provided on the roller shutter beams 2. The two ends of the roller shutter beams 2 are respectively provided with sliders 12 that can slide on the guide rails 4. The device also includes a pull-out drive mechanism provided on the guide rails 4. The pull-out drive mechanism includes a pair of driving wheels 6 located at the front end of the guide rail 4 and a pair of driven wheels 7 located at the rear end of the guide rail 4. The driving wheels 6 and driven wheels 7 are connected by an annular transmission belt 8. A pull-out motor 9 is provided on the outside of the driving wheels 6. The pull-out motor 9 is connected to the axle of the driving wheels 6 through a pull-out clutch 10. The axle of the driving wheels 6 passes through the guide rail 4 and is connected to the pull-out clutch 10.
[0027] The annular conveyor belt 8 is located outside the slider 12, and the roller shutter beam 2 includes a tail beam 11, with both ends of the tail beam 11 extending outward and connecting to the annular conveyor belt 8.
[0028] Both the driving wheel 6 and the driven wheel 7 are sprockets, and the annular transmission belt 8 is a chain. The combination of sprockets and chains provides high transmission accuracy and strong load-bearing capacity. During the operation of the rainproof device on the vertical take-off and landing aircraft platform, it ensures stable power transmission between the driving wheel 6 and the driven wheel 7, making the roll-up curtain's unfolding action more accurate and avoiding problems such as curtain jamming caused by transmission errors. The overall operation of the rainproof device is stable and reliable.
[0029] Both the driving wheel 6 and the driven wheel 7 are synchronous pulleys, and the annular transmission belt 8 is a synchronous belt. During the operation of the rainproof device on the vertical take-off and landing aircraft platform, the coordinated transmission between the synchronous pulleys and the synchronous belt ensures smooth transmission, meets the stable deployment requirements of the telescopic shutter, has low noise, and low maintenance costs.
[0030] The rainproof cloth 3 is made of non-woven fabric or plastic film. Non-woven fabric is lightweight, yet possesses a certain strength and durability, enabling it to provide rain protection while reducing its impact on the overall weight of the aircraft platform. Its softness also makes the roll-up curtain easier to unfold and retract, reducing the likelihood of damage. Plastic film, on the other hand, offers excellent waterproof performance and good flexibility, effectively preventing rainwater penetration. It can closely conform to the shape of the roll-up curtain, and its relatively low cost and ease of replacement further enhance the practicality and economy of the rainproof device.
[0031] It also includes a roller shutter box 13, within which the roller shutter tube 5 is rotatably mounted. The roller shutter tube 5 rotates under the action of a roller drive mechanism, which includes a roller motor 14 connected to the roller shutter tube 5 via a roller clutch 15. The roller shutter box 13 provides storage space for the roller shutter tube 5, effectively protecting the roller shutter tube 5 and its drive components from external environmental interference and damage. The roller motor 14 serves as the power source and is connected to the roller shutter tube 5 via the roller clutch 15. When the roller shutter tube 5 needs to be retracted, the roller clutch 15 can connect the roller motor 14 and the roller shutter tube 5's shaft, realizing the power transmission of the roller shutter tube 5. The roller motor 14 operates, and the roller shutter tube 5's shaft rotates to complete the retraction of the roller shutter. When the roller shutter needs to be unfolded, the roller clutch 15 disconnects the roller motor 14 from the roller shutter tube 5's shaft, and the pull-out clutch 10 connects the pull-out motor 9 and the drive wheel 6. The pull-out motor 9 operates, and the annular conveyor belt 8 drives the tail beam 11 to move towards the tail end of the guide rail 4, thereby unfolding the retractable roller shutter. This allows the retractable roller shutter to cover the atrium, protecting it from or even reducing the entry of rainwater.
[0032] The system also includes an electronic control system, comprising a controller and an angle encoder 16. The angle encoder 16 is mounted on the pull-out motor 9. The controller receives signals from the angle encoder 16 and controls the actions of the pull-out clutch 10, the pull-out motor 9, the drum clutch 15, and the drum motor 14. By implementing this electronic control system, the pull-out clutch 10, the pull-out motor 9, the drum clutch 15, and the drum motor 14 can be precisely controlled to operate according to a program, automating the unfolding and retraction of the telescopic roller shutter. The angle encoder 16 provides real-time feedback on the rotation angle information of the pull-out motors 9 on both sides of the guide rail 4. Based on these signals, the controller precisely controls the actions of the pull-out motors 9 on both sides, ensuring that the telescopic roller shutter can be accurately unfolded to the required position. This significantly improves the operational accuracy and reliability of the rainproof device, further enhancing the protective capabilities of the vertical take-off and landing aircraft platform in rainy weather.
[0033] The angle encoder 16 includes a first angle encoder and a second angle encoder. The pull-out motor 9 includes a first pull-out motor and a second pull-out motor. The first pull-out motor is located outside the right guide rail 4, and the second pull-out motor is located outside the left guide rail 4. The pull-out clutch 10 includes a first pull-out clutch and a second pull-out clutch. The first pull-out clutch is located between the first pull-out motor and the right drive wheel 6, and the second pull-out clutch is located between the second pull-out motor and the left drive wheel 6.
[0034] The upper surface of the roller shutter box 13 is flush with the guide rail 4, and the height difference between the highest point of the guide rail 4 and the platform body 1 is less than 200mm. The roller shutter box 13 is suspended on the platform body 1, its upper surface is flush with the guide rail 4, and the height difference between the guide rail 4 and the platform body 1 is less than 200mm. Considering that the vertical take-off and landing aircraft does not allow any buildings within a distance of at least three meters around the platform body 1 that are 250mm higher than the platform body 1, the height space occupied by the roller shutter box 13 and the guide rail 4 on the platform body 1 is reduced to avoid interfering with the take-off and landing of the vertical take-off and landing aircraft.
[0035] The roller shutter beam 2 includes an upper beam and a lower beam, with the rainproof cloth 3 sandwiched between the upper and lower beams. This increases the beam's support strength, providing stable support for the rainproof cloth 3 and ensuring the reliability of the rainproof device's deployment and retraction, thus better protecting the vertical take-off and landing aircraft platform. If the retractable roller shutter requires even stronger support, a more rigid roller shutter beam 2 can be used, and the spacing between adjacent roller shutter beams 2 can be reduced.
[0036] The annular conveyor belt 8 includes a conveying section and a return section located below the conveying section. Both ends of the tail beam 11 are connected to the return section. Connecting the tail beam 11 to the return section of the annular conveyor belt 8 lowers the position of the retractable roller shutter as much as possible, placing it below the guide rail 4, thus making the unfolding and retraction of the roller shutter more stable. To avoid affecting the sliding contact 12 on the beam against the guide rail 4, a connecting rod can be added between the tail beam 11 and the annular conveyor belt 8 to adjust the connection angle.
[0037] To ensure drainage, during installation, the front end of the guide rail 4 is higher than its rear end. Water on the rainproof cloth 3 can flow to the lower rear end of the guide rail 4. A water guide channel 17 can be installed on the platform body 1. Water on the rainproof cloth 3 will flow into the water guide channel 17 and then be discharged through the drainage pipes inside the building that are connected to the water guide channel 17. To facilitate water drainage, the water guide channel 17 can be higher in the middle and lower at both ends. In this way, the outlets at both ends can flow smoothly into the drainage pipes on both sides of the building, ensuring timely and effective drainage and preventing water accumulation on the platform body 1.
[0038] A drain outlet can also be provided on the roller shutter box 13. Water can be drained periodically, and water can be discharged into the building's drainage system through connecting pipes. When a small amount of water enters the roller shutter box 13 with the retractable roller shutter, it can be discharged in a timely manner.
[0039] During operation, when the retractable roller shutter needs to be retracted, the pull-out clutch 10 disengages, the drum clutch 15 engages, the drum motor 14 operates, and drives the roller shutter drum 5 to retract the roller shutter; when the retractable roller shutter needs to be pulled out, the pull-out clutch 10 engages, the drum clutch 15 disengages, the pull-out motor 9 operates, and drives the tail beam 11 to pull out the retractable roller shutter, thereby covering the atrium of the platform; angle encoders 16 are installed on the left and right pull-out motors 9 respectively, which can calculate the speed difference between the two sides through the controller, and then maintain synchronization between the left and right sides by adjusting the frequency of the inverter of the corresponding motor. The combination of the rainproof cloth 3 and the roller blind beam 2 in this utility model enables the telescopic roller blind to have a waterproof function. The combination of the pull-out drive mechanism and the tail beam 11 makes it more convenient and faster for the telescopic roller blind to unfold and cover the atrium. The telescopic roller blind has a lightweight structure, is easy to drive and consumes little energy. Using the rainproof cloth 3 as the roller blind can also greatly reduce the size of the roller blind tube 5, and reduce the volume of the roller blind box 13 that houses the roller blind tube 5. The pull-out motor 9 is set coaxially with the drive wheel 6, which reduces the height space occupied by the motor compared with the vertically installed motor. It can meet the height restrictions of the aircraft on the periphery of the platform body 1, solve the problem of inconvenient installation due to the height restrictions around the aircraft's lifting platform, and improve the convenience and reliability of the rainproof device.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
