Description

Technical Field

[0001] The present invention relates to a helipad technology, in particular to a helicopter helipad landing assist system. Background Art

[0002] A rooftop helipad is a facility located on a building's rooftop for helicopter takeoff, landing, and parking. Some hospitals and other medical institutions are gradually installing helipads on their rooftops to facilitate multi-channel emergency medical rescue. Existing hospital rooftop helipads facilitate the transportation of patients and medical staff, increasing transport efficiency.

[0003] Traditional helipad signal lights and transmitters are installed on the landing pad. This reduces their service life when not in use or in inclement weather. Furthermore, the signal lights and transmitters are tightly packed together, making wiring difficult and hindering automatic centering for helicopter landings.

[0004] CN208337958U discloses a helicopter landing pad that uses external signal lights. This design not only affects helicopter landing but can also damage sensors or signal lights in the middle. Furthermore, the exposed signal lights or signal transmitters are exposed to the elements, directly reducing their service life and affecting the helicopter's automatic centering landing.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] like Figures 1 to 13 As shown, the helipad landing assist system of the present invention includes a helipad surface 1 and a signaling mechanism 2. The signaling mechanism 2 is used to enable a helicopter to automatically and smoothly land on the helipad surface 1 in a centered manner. When not in use, the through-hole 4 is covered by a cover plate 3, thereby concealing the adjustment assembly 5. This protects the adjustment assembly 5 and prevents it from being affected or interfered with by external environmental factors, thereby extending the service life of the signal light or signal device.

[0042] The apron surface 1 is composed of an inner apron surface 6 and an outer apron surface 7 , and a sign 8 is provided in the middle of the inner apron surface 6 .

[0043] Signal mechanism 2, used to assist the helicopter in automatic centering landing, is located at the lower end of outer landing surface 7. Signal mechanism 2 consists of an adjustment assembly 5 that can be converted into a signal indicator or signal light, and a movable assembly 9 that can keep the adjustment assembly 5 hidden. The movable assembly 9 is connected to the adjustment assembly 5 by a connecting rod 10.

[0044] When the adjusting assembly 5 is moved toward the movable assembly 9 by an external force, the movable assembly 9 will be kept moving downward during the forward movement, so that the adjusting assembly 5 reaches the position where the movable assembly 9 originally stopped. As a result, the cover plate 3 is pushed to the lower end of one side of the through hole 4, and the mounting member 11 is pushed to the right lower end of the through hole 4, so that the signal lamp installed on the mounting member 11 can illuminate the light or the signal device can emit an indication signal.

[0045] Moreover, when it is not in need of operation, the cover plate 3 can be kept covering the through hole 4, so that the mounting part 11 is hidden, which is beneficial to the cleanliness of the apron surface 1 and keeps the signal mechanism 2 in a hidden state, so that the signal mechanism 2 will not be damaged due to improper operation.

[0046] The adjustment assembly 5 includes a mounting member 11, a guide rail 12, a drive assembly 13, and a pusher 14. The mounting member 11 is used to mount the signal light and annunciator. The guide rail 12 is used to provide the mounting member 11 with horizontal movement. The drive assembly 13 is used to drive the mounting member 11 to move toward the movable assembly 9. The pusher 14 is used to maintain the mounting member 11 to receive the external force of the drive assembly 13. One end of the pusher 14 is hinged to the first hinge seat 15, and the other end is hinged to the rotating shaft 16.

[0047] One end of the mounting member 11 is provided with symmetrical rollers 17, and the other end is provided with a first hinge seat 15. The rollers 17 are arranged at the hinge of a vertical surface 18 and a horizontal surface 19, and the first hinge seat 15 is installed on the horizontal surface 19.

[0048] Mounting member 11 comprises a horizontal surface 19, a vertical surface 18, and an arcuate surface 20. The angle between horizontal surface 19 and vertical surface 18 is 90°. Arcuate surface 20 faces upward and, when not in operation, is located to one side of the lower end of cover plate 3. Furthermore, the length of horizontal surface 19 is greater than that of vertical surface 18, so that arcuate surface 20 extending from one end of vertical surface 18 to one end of horizontal surface 19 is formed of arcs of different diameters. By forming arcs of different diameters, the distances from the arcs of different diameters to the central axis 24 of roller 17 can be maintained at different distances, thereby enabling signal lights or signal devices installed at different locations to illuminate light or transmit signals vertically upward at different angles.

[0049] like Figure 13 As shown, the arc surface 20 is composed of a first arc segment 21, a second arc segment 22 and a third arc segment 23, and the distances from the first arc segment 21, the second arc segment 22 and the third arc segment 23 to the central axis 24 of the roller 17 are P1, P2 and P3 respectively, wherein P1<P2<P3.

[0050] like Figure 12 As shown, the mounting member 11 is now positioned exactly at the lower end of the through hole 4. When six different components are positioned on the curved surface 20 of the mounting member 11, the six components are positioned at different distances from the central axis 24 of the roller 17, resulting in each component having a different upward angle. These are M1, M2, M3, M4, M5, and M6. The mounting member 11 has now been rotated to a certain angle, with M3 in the figure being perpendicular to the ground, enabling a better launch angle. The other five components are tilted, but the mounting member 11 can be rotated to maintain a vertical position, allowing the various components to be used either tilted or vertically.

[0051] A pressure member 25 is provided on the vertical surface 18. This pressure member 25 can maintain its deformation under the external force of the connecting rod 10. This pressure member 25 can cause the mounting member 11 to rotate, driving the connecting rod 10 downward, thereby also moving the cover plate 3 downward. Furthermore, the mounting member 11 can push the cover plate 3 downward, causing it to descend from the through hole 4 and shift position. The deformation capacity of the pressure member 25 is smaller than the elastic force of the reset member 26, allowing the pressure member 25 to compress the reset member 26 after reaching its deformation limit.

[0052] The mounting member 11 is mounted on the guide rail 12 via rollers 17. A support panel 27 is provided in the middle of the guide rail 12, connecting the symmetrical guide rails 12. A first fixing member 28 is provided at one end of the guide rail 12, and a second fixing member 29 is provided at the other end. The upper ends of the first fixing member 28 and the second fixing member 29 are both connected to the lower end of the outer floor 7. A notch 30 is provided in the middle of the first fixing member 28 for the cover plate 3 to pass through. The width of the notch 30 is greater than the width of the cover plate 3, making it easier for the cover plate 3 to pass through the notch 30.

[0053] The pusher 14 is composed, from top to bottom, of a first hinged end 31, a first connecting section 32, a second connecting section 33, a third connecting section 34, a fourth connecting section 35, and a second hinged end 36. The first hinged end 31 is connected to the rotating shaft 16, and the second hinged end 36 is connected to the first hinge seat 15. The first hinge seat 15 is provided with a second hinge shaft 37, and the second hinged end 36 is hinged to the second hinge shaft 37. An accommodating area 38 for accommodating the mounting member 11 is formed between the first connecting section 32, the second connecting section 33, the third connecting section 34, and the fourth connecting section 35.

[0054] The angle between the first connecting section 32 and the rotating member 39 is 0-70 degrees. The angle between the third connecting section 34 and the fourth connecting section 35 is 120-130 degrees, so that the third connecting section 34 and the fourth connecting section 35 are not arranged vertically or horizontally.

[0055] One end of the drive assembly 13 is hinged to the lower end of the outer deck 7. The other end is equipped with a rotating member 39. Rotating member 39 is equipped with a rotating shaft 16, which is mounted to the lower end of the outer deck 7 via a second hinge seat 40. The drive assembly 13 is a cylinder. The lower end of the outer deck 7 is equipped with a third hinge seat 41, and the lower end of the third hinge seat 41 is equipped with a fixed block 42. This fixed block 42 is connected to the drive assembly 13, allowing the drive assembly 13 to be fixed and rotated during operation.

[0056] There is a distance difference between one end of the rotating member 39 and the other end. The rotating member 39 is connected to the drive assembly 13 via a first hinge shaft 43. When the first hinge shaft 43 is pushed by the drive assembly 13, it can drive the rotating shaft 16 to rotate, thereby maintaining the rotating shaft 16 to drive the pusher 14 to rotate. The rotating member 39 and the pusher 14 are fixed to the rotating shaft 16. The pusher 14 rotates the same angle as the rotating member 39.

[0057] like Figure 10 As shown, in addition, a vertical line 44 is set downward from the center line of the second hinge seat 40, and the distance between the vertical line 44 and the first hinge axis 43 is H1. The angle between the first connecting section 32 on the pusher 14 and the vertical line 44 is S1, and the angle range of S1 is 0-70°, so that the rotating member 39 can be changed between 0-70°, that is, the angle between the rotating member 39 and the first connecting section 32 is changed.

[0058] When the drive assembly 13 pushes the rotating member 39, H1 continues to shrink, and the mounting member 11 now rolls and translates on the guide rail 12, rather than rotating about the roller 17. Only after the first hinge axis 43 crosses the vertical line 44 does the pushing member 14 push the mounting member 11 to both roll and rotate, maintaining the upward lift of the horizontal plane 19. Components at different positions on the curved surface 20 also experience changes in angle, allowing different components to operate vertically upwards according to the extension and contraction of the drive assembly 13.

[0059] The movable component 9 is composed of a cover plate 3, a positioning rod 45 and a reset member 26. A through hole 4 for placing the cover plate 3 is provided on the outer floor surface 7. A through hole 46 for the positioning rod 45 to pass through is provided on the support panel 27. The reset member 26 is sleeved on the positioning rod 45. One end of the connecting rod 10 is hinged to the lower end of the cover plate 3, and the other end is hingedly connected to the mounting member 11.

[0060] One end of the connecting rod 10 is connected to the cover plate 3 via a fourth hinge seat 47 , and the other end is connected to the vertical surface 18 of the mounting member 11 via a fifth hinge seat 48 .

[0061] The cover plate 3 is provided with a first inclined surface 49 , and the through hole 4 is provided with a second inclined surface 50 that cooperates with the first inclined surface 49 . The cover plate 3 can be pushed with the assistance of the connecting rod 10 , thereby cooperating with the second inclined surface 50 to move the cover plate 3 downward.

[0062] Through-hole 46 is a strip-shaped hole, through which positioning rod 45 can slide. Positioning rod 45 is covered with a sliding sleeve 51, which is located at the lower end of reset member 26 and attached to support panel 27. The diameter of sliding sleeve 51 is larger than that of reset member 26. Reset member 26 can maintain the position of cover plate 3 and also reset it.

[0063] When a helicopter needs to land, the drive assembly 13 receives a signal from the control room and activates, moving in the direction of F1 while the rotating member 39 rotates in the direction of F2. This reduces the distance H1, causing the mounting member 11 to translate first. The drive assembly 13 then continues to rotate the rotating member 39, causing the mounting member 11 to transition from a translational state to a simultaneous translational state. The pusher 14 continues to push the mounting member 11 until it reaches the lower end of the through hole 4.

[0064] In addition, after the drive assembly 13 is activated, the cover plate 3 connected to the mounting member 11 will also be subjected to the thrust from the connecting rod 10. When the first hinge axis 43 crosses the vertical line 44, the pressure member 25 will contact the connecting rod 10. As the mounting member 11 continues to move, the pressure member 25 will deform, keeping the connecting rod 10 under downward force, thereby driving the cover plate 3 downward. Furthermore, the cooperation between the first inclined surface 49 and the second inclined surface 50 enables the cover plate 3 to move away from the mounting member 11 while moving downward, thereby opening the through hole 4, and the cover plate 3 moves into the notch 30 of the first fixing member 28, while the mounting member 11 moves to the exact lower end of the through hole 4, facilitating the illumination of a signal light or the transmission of a signal, thereby facilitating the automatic centering landing of the helicopter.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
