Description

Technical Field

[0001] This invention belongs to the field of helipad technology and relates to a mobile helipad with a pneumatic deflector deck. Background Technology

[0002] With the increasing use of helicopters in emergency rescue, field operations, and military operations, the demand for temporary take-off and landing sites is becoming more and more urgent. Traditional fixed helipads are limited by long construction cycles and fixed locations, and cannot meet the needs of rapid deployment and flexible relocation. Therefore, mobile helipads have gradually become a research hotspot.

[0003] However, existing mobile helipads have significant drawbacks in practical use: helicopter takeoffs and landings generate high-intensity downwash airflow, which, upon impacting the helipad deck surface, easily creates turbulent airflow. This not only causes a sudden increase in deck surface pressure, triggering severe vibrations and affecting the structural stability and service life of the helipad, but also may interfere with helicopter takeoff and landing attitudes, increasing safety risks. Furthermore, while some mobile helipads attempt to incorporate simple airflow guiding structures, the guiding paths are fixed and cannot be adjusted according to airflow intensity, resulting in limited guiding effects. They also lack centralized airflow guidance and pressure stabilization designs, making it difficult to fundamentally solve the turbulence and vibration problems. In addition, the auxiliary structures of existing mobile helipads (such as towing components) mostly only have mobility functions and do not coordinate with the airflow guiding system, further reducing overall performance. Therefore, there is an urgent need to design a mobile helipad with an aerodynamic airflow guiding deck that can overcome these shortcomings.

[0004] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a mobile helipad [application number: 202022692685.4], which consists of a trailer mobile platform and a container body. The trailer mobile platform includes a trailer chassis and drive wheels. The container body is bolted to the upper surface of the trailer chassis. The traction end on the upper surface of the trailer chassis is equipped with an auxiliary mechanism for assisting in the disassembly and assembly of the container body. Several telescopic support columns are provided on the lower surface of the trailer chassis. This mobile helipad uses a tractor unit to tow the trailer chassis, which conforms to existing trailer towing methods. However, this solution still cannot achieve efficient guidance and pressure stabilization of airflow during helicopter take-off and landing, and cannot significantly reduce turbulence and vibration on the deck surface, resulting in poor safety, stability, and applicability of the mobile helipad. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a mobile helipad with a pneumatic airflow deck.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: A mobile helipad with a pneumatic airflow guide plate includes a mobile frame with several drive wheels at its bottom and auxiliary traction plates at its front and rear ends. A helipad is mounted on the mobile frame, and the helipad contains several airflow guide holes arranged in a circular array along its center point. The helipad also contains a rotatable and adjustable pneumatic airflow guide structure, the position of which corresponds to the airflow guide holes. The mobile frame has a cavity, and the auxiliary traction plates contain auxiliary airflow guides. A central pressure-stabilizing base plate is located at the bottom of the mobile frame. A supporting airflow guide assembly is located within the cavity to support the adjustable pneumatic airflow guide structure and guide airflow to the central pressure-stabilizing base plate. When the adjustable pneumatic airflow guide structure rotates downwards and abuts against the supporting airflow guide assembly, the helipad and the cavity within the mobile frame form an airflow channel.

[0007] In the aforementioned mobile landing pad with a pneumatic guide deck, the adjustable pneumatic guide structure includes several guide vanes installed within the landing deck, and the guide vanes are driven by a forward and reverse reversing motor.

[0008] In the aforementioned mobile parking apron with a pneumatic guide vane, the parking vane is provided with a blade support surface, and a rubber pad is provided on the blade support surface. When the guide vane rotates downward, the rubber pad and the support guide assembly respectively abut against the guide vane, and the position of the guide vane corresponds to the guide hole.

[0009] In the aforementioned mobile apron with a pneumatic flow guide plate, the supporting flow guide assembly includes a support seat disposed in a cavity, the support seat is provided with several supporting inclined surfaces corresponding to the positions of the flow guide plates, the support seat has an internal flow guide cavity, the mobile frame has a bottom flow guide channel connected to the internal flow guide cavity, and the middle pressure stabilizing base plate is located below the bottom flow guide channel.

[0010] In the aforementioned mobile helipad with a pneumatic guide deck, the central pressure stabilizing base plate includes a pressure stabilizing base plate disposed at the bottom of the mobile frame. The pressure stabilizing base plate is connected to the mobile frame via a connecting rod. The pressure stabilizing base plate is provided with an adjustable sliding plate that can slide up and down and engages with the mobile frame.

[0011] In the aforementioned mobile landing pad with a pneumatic guide deck, the cross-section of the pressure stabilizing base plate is annular, and the adjusting slide plate includes a sliding ring plate disposed on the pressure stabilizing base plate. The sliding ring plate and the pressure stabilizing base plate are slidably engaged through a limiting block, and the top of the sliding ring plate can be interference-fitted with the bottom slot of the mobile frame.

[0012] In the aforementioned mobile landing pad with a pneumatic guide deck, the auxiliary guide section includes a plurality of auxiliary guide inclined holes disposed within the auxiliary traction deck, the auxiliary guide inclined holes being arranged at an inclination.

[0013] In the aforementioned mobile helipad with a pneumatic flow guide deck, the mobile vehicle frame has connecting flow guide ports at both the front and rear ends, and the connecting flow guide ports are located between the cavity and the auxiliary flow guide oblique holes.

[0014] In the aforementioned mobile landing pad with a pneumatic guide deck, the top of the connecting guide port has a slope.

[0015] In the aforementioned mobile parking apron with a pneumatic guide deck, the bottom of the auxiliary traction deck is equipped with rotatable auxiliary rollers.

[0016] Compared with existing technologies, the advantages of this invention are: 1. During use, the present invention, through the cooperation of the adjustable aerodynamic guide structure and the supporting guide component, can drive the guide vanes to rotate by a forward and reverse motor according to the helicopter model and the airflow intensity during takeoff and landing. This allows for flexible control of the opening size of the guide channel and the airflow guidance angle. Compared with the traditional fixed guide structure, it can guide the airflow more accurately and avoid the accumulation of airflow on the deck surface to form turbulence.

[0017] 2. In this invention, after the airflow enters the cavity through the guide channel, part of it is guided by the internal guide cavity of the supporting guide assembly and the bottom guide channel to the middle pressure stabilizing base plate. The annular structure of the pressure stabilizing base plate is used to achieve uniform airflow diffusion and reduce local airflow pressure. The other part is guided by the auxiliary guide inclined hole of the auxiliary traction deck through the guide port to achieve secondary dispersion of airflow, further reducing the airflow impact and vibration on the deck surface.

[0018] The central stabilizing base plate in this invention is connected to the mobile frame via a connecting rod, and the adjustable sliding plate can slide up and down and is interference-fitted with the bottom slot of the mobile frame. This not only enhances the contact stability between the helipad and the ground through the stabilizing base plate, but also adapts to different ground flatness by adjusting the sliding plate to prevent the helipad from tilting. At the same time, the drive wheels at the bottom of the mobile frame cooperate with the auxiliary rollers at the bottom of the auxiliary traction deck to ensure that the helipad can move and turn flexibly to meet the needs of rapid deployment.

[0019] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, a mobile helipad with a pneumatic airflow guide plate includes a mobile frame 1. The bottom of the mobile frame 1 is provided with several drive wheels 2. The front and rear ends of the mobile frame 1 are provided with auxiliary traction plates 3. The mobile frame 1 is provided with a helipad 4. The helipad 4 has several airflow guide holes 5 arranged in a ring array along the center point of the helipad 4. The helipad 4 is also provided with a rotatable and adjustable pneumatic airflow guide structure 6. The position of the adjustable pneumatic airflow guide structure 6 corresponds to the position of the airflow guide holes 5. The mobile frame 1 has a cavity 7. The auxiliary traction plate 3 has an auxiliary airflow guide part 8. The bottom of the mobile frame 1 is also provided with a central pressure stabilizing base plate 9. The cavity 7 is provided with a supporting airflow guide assembly 10 for supporting the adjustable pneumatic airflow guide structure 6 and guiding the airflow to the central pressure stabilizing base plate 9. When the adjustable pneumatic airflow guide structure 6 rotates downward and abuts against the supporting airflow guide assembly 10, the helipad 4 and the cavity 7 in the mobile frame 1 form an airflow guide channel.

[0028] In this embodiment, when the helicopter is preparing to land, the adjustable aerodynamic guide structure 6 rotates downward until its bottom abuts against the top of the support guide assembly 10. At this time, the guide hole 5 of the landing deck 4 is connected to the inlet of the support guide assembly 10, and the lower surface of the landing deck 4 and the top of the cavity 7 form a closed guide channel. After the airflow enters the guide channel through the guide hole 5, part of it flows to the support guide assembly 10 and is finally guided to the central pressure stabilizing base plate 9, and the other part flows to the auxiliary traction deck 3 through the communication structure between the cavity 7 and the auxiliary guide part 8. Traditional mobile helipads lack a complete airflow channel design, leading to turbulent airflow on the deck surface. This device, through a combination of "airflow guide hole 5 + adjustable pneumatic airflow guide structure 6 + supporting airflow guide component 10 + cavity 7", constructs an openable / closeable and adjustable airflow guide channel, guiding the airflow from the deck surface to the interior and bottom of the helipad, reducing turbulence at the source. At the same time, the addition of auxiliary airflow guide 8 and central pressure stabilizing base plate 9 breaks the functional limitation of the traditional "single deck" helipad, achieving multi-path dispersion of airflow and further improving the pressure stabilization effect.

[0029] Combination Figure 1-5 As shown, the adjustable pneumatic guide structure 6 includes several guide vanes 11 disposed in the parking deck 4, and the guide vanes 11 are driven by a forward and reverse reversing motor.

[0030] Specifically, the adjustable aerodynamic guide structure 6 includes guide vanes 11 and a forward / reverse motor (not shown in the figure, preferably a servo motor). The number of guide vanes 11 is the same as the number of guide holes 5, and the size of each guide vane 11 is slightly larger than the diameter of the guide hole 5 (to ensure complete coverage of the guide hole 5). The forward / reverse motor is fixed in a mounting slot inside the landing deck 4 by a bracket, and the motor output shaft is connected to the rotation shaft of the guide vane 11 by a coupling. The forward / reverse motor receives control signals (which can be triggered by a remote controller or helicopter landing sensor) and drives the guide vane 11 to rotate around the rotation shaft. Clockwise or counterclockwise rotation: When the motor rotates clockwise, the guide vane 11 flips downward and gradually approaches the supporting guide assembly 10; when the motor rotates counterclockwise, the guide vane 11 flips upward and gradually covers the guide hole 5, closing the guide channel. By using a forward and reverse motor to drive the guide vane 11, the guide angle can be infinitely adjusted (for example, when the airflow intensity is high, the guide vane 11 is fully opened to increase the guide area; when the airflow intensity is low, the guide vane 11 is partially opened to avoid excessive guide flow leading to negative pressure on the deck), achieving dynamic adaptation of the guide effect and improving applicability in different scenarios.

[0031] The parking deck 4 is provided with a blade support surface 12, and a rubber pad 13 is provided on the blade support surface 12. When the guide blade 11 rotates downward, the rubber pad 13 and the support guide assembly 10 respectively abut against the guide blade 11. The guide blade 11 is positioned corresponding to the guide hole 5.

[0032] In this embodiment, when the guide vane 11 rotates downward to the working position, its bottom edge abuts against the supporting inclined surface of the guide assembly 10, while its top edge is tightly fitted with the rubber pad 13 on the vane support surface 12. The rubber pad 13 forms an elastic buffer layer between the guide vane 11 and the vane support surface 12, and fills the gap between them. In traditional guide structures, the vane and the support surface are mostly in hard contact, which is prone to increased gap and airflow leakage due to vibration, and is also prone to wear due to long-term collision. This application adds the rubber pad 13 to achieve a sealed fit between the guide vane 11 and the vane support surface 12, and avoids airflow leakage from the gap, which affects the guide efficiency.

[0033] Combination Figure 1 , Figure 2 As shown, the support and guide assembly 10 includes a support seat 100 disposed in the cavity 7. The support seat 100 is provided with a plurality of support inclined surfaces corresponding to the positions of the guide vane 11. The support seat 100 has an internal guide cavity 101. The mobile frame 1 has a bottom guide channel 14 connected to the internal guide cavity 101. The middle pressure stabilizing base plate 9 is located below the bottom guide channel 14.

[0034] In this embodiment, the support and guide assembly 10 includes a support base 100, an internal guide cavity 101, and a bottom guide channel 14. The support base 100 is a hollow conical structure fixed to the bottom of the cavity 7. Its top has a support ramp (with an angle of 30°-45°, adapting to the rotation angle of the guide vane 11) corresponding to the positions of the guide vane 11. The internal guide cavity 101 is a hollow channel inside the support base 100 (connected to the opening of the support ramp). The bottom guide channel 14 is a strip-shaped channel located at the bottom of the mobile frame 1, with one end connected to the bottom of the internal guide cavity 101 and the other end extending directly above the central pressure-stabilizing base plate 9. Airflow passes through the guide vane. After being guided by 11, the airflow flows into the internal guide cavity 101 along the support slope of the support base 100. Due to the conical structure of the support base 100, the airflow converges and accelerates in the internal guide cavity 101. Then, it flows smoothly to the middle pressure stabilizing base plate 9 through the bottom guide channel 14. The support base 100 is designed as a "conical + internal guide cavity 101" structure, which enables it to have the dual functions of "supporting the guide vane 11" and "guiding the airflow". The bottom guide channel 14 accurately guides the airflow to the middle pressure stabilizing base plate 9, avoiding disorderly diffusion of the airflow in the cavity 7.

[0035] The central pressure stabilizing base plate 9 includes a pressure stabilizing base plate 15 disposed at the bottom of the mobile frame 1. The pressure stabilizing base plate 15 is connected to the mobile frame 1 by a connecting rod. The pressure stabilizing base plate 15 is provided with an adjusting slide plate 16 that can slide up and down and engages with the mobile frame 1.

[0036] In this embodiment, the central pressure-stabilizing base plate 9 includes a pressure-stabilizing base plate 15, connecting rods (not shown in the figure, preferably metal screws, in quantity 4-6), and an adjusting slide plate 16. The adjusting slide plate 16 is a ring-shaped plate structure, sleeved on the outside of the pressure-stabilizing base plate 15 and can slide up and down along the pressure-stabilizing base plate 15. The bottom of the mobile frame 1 has a slot corresponding to the top of the adjusting slide plate 16. When the helipad needs to be fixed, the connecting rod is rotated to shorten its length, causing the pressure-stabilizing base plate 15 to move downward until it contacts the ground. Then, the adjusting slide plate 16 is pushed upward so that its top is pressurized and engaged with the slot at the bottom of the mobile frame 1, thereby locking the position of the pressure-stabilizing base plate 15. When the helipad needs to be moved, the adjusting slide plate 16 is pulled downward to disengage from the slot, and the connecting rod is rotated to extend its length, causing the pressure-stabilizing base plate 15 to move upward and lift off the ground, avoiding interference with the drive wheel 2.

[0037] Combination Figure 1-5 As shown, the cross-section of the voltage stabilizing base plate 15 is annular, and the adjusting slide plate 16 includes a sliding ring plate 17 disposed on the voltage stabilizing base plate 15. The sliding ring plate 17 and the voltage stabilizing base plate 15 are slidably engaged through a limiting block 18. The top of the sliding ring plate 17 can be interference-fitted with the bottom slot of the mobile frame 1.

[0038] In this embodiment, the sliding ring plate 17 slides in conjunction with the limiting block 18 of the pressure stabilizing base plate 15 through the sliding groove, and can only move up and down along the axial direction of the pressure stabilizing base plate 15, but cannot rotate; when the sliding ring plate 17 slides upward to the limit position, the protrusion at its top is pressurized into the annular groove at the bottom of the mobile frame 1, and the friction of the pressurized fit is used to fix the sliding ring plate 17; when it is necessary to unlock, applying a downward external force can make the protrusion disengage from the groove.

[0039] The auxiliary flow guiding section 8 includes a plurality of auxiliary flow guiding inclined holes 19 disposed in the auxiliary traction deck 3, and the auxiliary flow guiding inclined holes 19 are inclined.

[0040] In this embodiment, part of the airflow in the cavity 7 that does not flow to the supporting guide assembly 10 flows to the auxiliary guide inclined hole 19 through the communication area between the movable frame 1 and the auxiliary traction deck 3. Due to the inclined structure of the auxiliary guide inclined hole 19, the airflow is guided to the lower outer side of the auxiliary traction deck 3, avoiding the airflow from flowing upward and impacting the deck surface.

[0041] Combination Figure 1-5 As shown, the mobile frame 1 has connecting guide ports 20 at both the front and rear ends, and the connecting guide ports 20 are located between the cavity 7 and the auxiliary guide inclined hole 19.

[0042] In this embodiment, the airflow in the cavity 7 flows from the inside of the mobile frame 1 to the inside of the auxiliary traction deck 3 through the connecting guide port 20. The connecting guide port 20 serves as a transition channel for the airflow, guiding the lateral airflow of the cavity 7 to the longitudinal inlet of the auxiliary guide inclined hole 19, thereby achieving a smooth conversion of the airflow direction.

[0043] Combination Figure 1-5 As shown, the top of the connecting guide port 20 has a slope.

[0044] In this embodiment, when the airflow flows from the cavity 7 to the connecting guide port 20, the inclined surface at the top of the connecting guide port 20 can guide the airflow to flow smoothly downward along the inclined surface, avoiding the airflow from hitting the top edge of the connecting guide port 20 and causing turbulence.

[0045] Combination Figure 1-5 As shown, the bottom of the auxiliary traction deck 3 is equipped with a rotatable auxiliary roller 21.

[0046] In this embodiment, the bottom of the auxiliary towing deck 3 is equipped with rotatable auxiliary rollers 21 (preferably omnidirectional wheels with braking function, 2-3 in number at the bottom of each auxiliary towing deck 3). The auxiliary rollers 21 are bolted to the bottom of the auxiliary towing deck 3 via brackets. When the mobile frame 1 moves via the drive wheels 2, the auxiliary rollers 21 at the bottom of the auxiliary towing deck 3 rotate in the direction of movement. If turning is required, the auxiliary rollers 21 can rotate 360° around the brackets to achieve flexible turning of the helipad. When the helipad is fixed, the position of the rollers can be locked by stepping on the brake device of the auxiliary rollers 21.

[0047] The working principle of this invention is: Operators can activate the power system (such as a hydraulic motor or electric motor) of the drive wheel 2 at the bottom of the mobile frame 1 via a remote controller or on-site control panel, and simultaneously release the brake lock of the auxiliary roller 21 at the bottom of the auxiliary traction deck 3. At this time, the drive wheel 2 provides active traction force, and the auxiliary roller 21 (universal wheel structure) rotates passively with the direction of movement. The two work together to move the entire helipad along a preset path, which is suitable for scenarios that require rapid transfer, such as emergency rescue and field operations. After the helipad moves to the target take-off and landing area, the brake device of the auxiliary roller 21 is first depressed to lock the rotational freedom of the auxiliary roller 21; then the connecting rod (threaded connection structure) of the central stabilizing base plate 9 is rotated to shorten the length of the connecting rod, which drives the stabilizing base plate 15 to move downward until the stabilizing base plate 15 is completely in contact with the ground, increasing the contact area between the helipad and the ground.Finally, push the adjusting slide plate 16 upwards so that its top engages with the slot at the bottom of the mobile frame 1, fixing the height of the stabilizing base plate 15 and preventing the helipad from tilting due to uneven ground, thus providing a stable foundation for subsequent helicopter take-off and landing. When the helicopter enters the take-off and landing airspace (approximately 50-100 meters from the helipad deck 4), the helipad's sensing system (such as radar or infrared sensors) triggers a signal, controlling the start of the forward and reverse motors of the adjustable aerodynamic guide structure 6. The forward and reverse motors drive the guide vane 11 to rotate clockwise around the rotation axis, causing the guide vane 11 to gradually flip downwards until the bottom of the guide vane 11 abuts against the supporting inclined surface of the guide assembly 10, while the top of the guide vane 11 is tightly fitted with the rubber pad 13 of the vane support surface 12. At this time, the airflow guide holes 5 of the landing deck 4 are connected to the internal airflow guide cavity 101 of the supporting airflow guide assembly 10. The lower surface of the landing deck 4 and the cavity 7 of the mobile frame 1 form a closed main flow channel. When the helicopter lands, the high-intensity downwash airflow impacts the surface of the landing deck 4. Most of the airflow enters the main flow channel through the annular array of airflow guide holes 5. The airflow is guided by the guide vane 11, flows through the support slope of the support seat 100 and enters the internal airflow guide cavity 101. Due to the conical structure of the support seat 100, the airflow converges in the internal airflow guide cavity 101 and forms a stable airflow bundle. Then, it flows through the bottom guide channel 14 to the pressure stabilizing base plate 15 of the middle pressure stabilizing base plate 9. The annular structure of the pressure stabilizing base plate 15 makes the airflow evenly diffused to the ground, avoiding excessive local airflow pressure. Large airflows cause the helipad to lift or vibrate. A small amount of airflow that does not enter the supporting guide assembly 10 flows within the cavity 7 and enters the auxiliary traction deck 3 through the connecting guide ports 20 at both ends of the mobile frame 1 (the top slope guides the airflow smoothly to avoid eddies). Finally, the airflow is guided to the lower outer side of the auxiliary traction deck 3 through the inclined auxiliary guide holes 19, achieving secondary dispersion of the airflow and further reducing the impact of the airflow on the edge of the helipad 4. Through the synergistic effect of the main flow channel (bottom pressure stabilization path) and the auxiliary guide channel (auxiliary dispersion path), the helicopter downwash airflow is quickly guided to the bottom and outer side of the helipad, preventing the airflow from accumulating on the surface of the helipad 4 and forming turbulence. Compared with traditional mobile helipads without a guide structure, the turbulence on the deck surface is much stronger. The vibration intensity is reduced by 60%-70%, and the vibration amplitude is controlled within 0.1-0.3mm (meeting the vibration standards for helicopter take-off and landing). At the same time, the elastic buffering effect of the rubber pad 13 can absorb the small vibrations generated by the airflow impact of the guide vane 11, preventing the vibration from being transmitted to the parking deck 4 and affecting the stability of the helicopter. If the intensity of the downwash airflow changes due to changes in the helicopter's load (such as carrying rescue supplies), the operator can adjust the speed of the forward and reverse motors through the controller to fine-tune the rotation angle of the guide vane 11 (for example, when the airflow is stronger, the guide vane 11 is fully opened to increase the guiding area; when the airflow is weaker, the guide vane 11 is partially closed to reduce airflow loss), ensuring that the guiding effect always matches the airflow intensity and maintaining the airflow stability on the surface of the parking deck 4. After the helicopter takes off and departs, the sensing system detects that there is no airflow impact on the parking deck 4. It controls the forward and reverse motors to rotate counterclockwise, driving the guide vanes 11 to flip upwards until the guide vanes 11 completely cover the guide holes 5, closing the main flow channel. At this time, the parking deck 4 returns to a flat state, which can prevent debris from entering the cavity 7 through the guide holes 5 and affecting the internal components. The operator releases the brake of the auxiliary roller 21, rotates the connecting rod of the central pressure stabilizing base plate 9, and extends the length of the connecting rod to move the pressure stabilizing base plate 15 upwards and off the ground. At the same time, the operator pulls down the adjusting slide plate 16 to disengage it from the slot of the moving frame 1, restoring the freedom of movement of the pressure stabilizing base plate 15. Then, the drive wheel 2 is started. Through the cooperation of the drive wheel 2 and the auxiliary roller 21, the parking apron is moved to the next work area, completing a complete take-off and landing operation cycle.
