Description

Technical Field

[0001] This invention relates to the technical field of aircraft ground facilities, specifically a vehicle-mounted aerodynamic unidirectional jet de-icing device and its de-icing method. Background Technology

[0002] Airplanes, as an important tool of modern transportation, have greatly shortened the time people spend traveling long distances, bringing immense convenience to travel. However, in actual flight, aircraft fuselages are prone to icing, especially under adverse weather conditions, where fuselage icing is even more common. Ice on the fuselage can pose flight safety hazards. Specifically, the adhesion of ice alters the aircraft's aerodynamic shape. Aircraft design is based on precise aerodynamic principles to ensure sufficient lift and stable flight attitude during flight. However, the adhesion of ice disrupts the integrity of this design, increasing drag and reducing the lift coefficient. Secondly, uneven distribution of ice can cause a shift in the aircraft's center of gravity, requiring pilots to exert more effort to maintain balance. Furthermore, ice can cover critical aircraft components such as sensors, antennas, and engine air intakes, affecting their normal function.

[0003] Therefore, ice on the aircraft posed a serious threat to flight safety. De-icing was not only a crucial step in ensuring flight safety but also a necessary measure to ensure the normal operation of the aircraft.

[0004] Aircraft fuselages typically have a curved shape. In actual flight environments, water droplets tend to accumulate towards the bottom of the fuselage due to gravity, resulting in a relatively thick ice layer there. Most existing de-icing methods employ high-speed airflow to melt the ice. However, this method has significant drawbacks. Firstly, the airflow needs to completely cover the ice layer, gradually melting it from thick to clear, and the airflow needs to be applied to every part of the fuselage for a sufficient duration, making the entire process time-consuming and inefficient. Secondly, it's easy to miss areas during the process, leading to incomplete de-icing and potential safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted pneumatic unidirectional jet de-icing device and method for de-icing the fuselage, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vehicle-mounted pneumatic unidirectional jet de-icing device for aircraft bodies includes a base mounted on a vehicle, and further includes:

[0008] The telescopic arm assembly is connected to the base. The end of the telescopic arm assembly away from the base is connected to a cross platform, and a nozzle for spraying high-speed airflow is inclinedly installed on the cross platform. The telescopic arm assembly can move relative to the base to change the position of the nozzle.

[0009] The assembly seat is slidably mounted on the horizontal platform, and the nozzle is movably mounted on the assembly seat. The horizontal platform is provided with a slide rail to guide the assembly seat. The two ends of the slide rail are the first working point and the second working point of the nozzle, respectively. The nozzle can be driven by the power mechanism mounted on the horizontal platform to move back and forth between the first working point and the second working point.

[0010] A swing mechanism is mounted on the mounting base and connected to the nozzle. The swing mechanism is used to drive the nozzle to swing back and forth at the first working point and the second working point. The nozzle is also connected to a deflection drive mechanism. When the nozzle reaches the second working point, the deflection drive mechanism is triggered, which can cause the nozzle to perform a deflection action to change the direction of the nozzle.

[0011] As a further embodiment of the present invention: the telescopic arm assembly includes a first long arm rotatably mounted on the base and a second long arm slidably fitted with the first long arm, and a first hydraulic cylinder is rotatably mounted on the base, the movable end of the first hydraulic cylinder being hinged to the first long arm.

[0012] A second hydraulic cylinder is provided on the first long arm, and the movable end of the second hydraulic cylinder is fixed to the second long arm. The cross platform is rotatably installed on one end of the second long arm away from the base, and a third hydraulic cylinder is rotatably installed on the second long arm, with the movable end of the third hydraulic cylinder hinged to the cross platform.

[0013] As a further embodiment of the present invention: the swing mechanism includes a guide structure disposed on the mounting base and a reciprocating movable component connected to the guide structure, the guide structure being connected to the nozzle, and the reciprocating movable component being able to move on the mounting base in a direction perpendicular to the slide.

[0014] As a further embodiment of the present invention: the guide structure includes an arc-shaped component fixedly installed on the mounting base, the arc-shaped component is provided with a guide groove, a slider is slidably fitted in the guide groove, the nozzle is rotatably installed on the slider, and the axial direction of the nozzle rotation axis is perpendicular to the slide rail;

[0015] The reciprocating motion component is connected to the slider, and the deflection drive mechanism is installed on the side of the slider and connected to the rotation shaft of the nozzle.

[0016] As a further embodiment of the present invention: the reciprocating moving component includes a guide rail disposed on the mounting base and a drive block slidably fitted on the guide rail, the drive block being connected to a threaded drive structure disposed on the mounting base;

[0017] The side of the slider is rotatably connected to a first follower arm via a shaft, and the side of the drive block is provided with a second follower arm. The first follower arm and the second follower arm are slidably connected. The side of the arc-shaped component is also provided with an arc-shaped through groove for the shaft to move.

[0018] As a further embodiment of the present invention: the deflection drive mechanism includes an elastic telescopic component disposed on the side of the slider and two sets of transmission structures connected to the elastic telescopic component, the two sets of transmission structures being respectively connected to both ends of the nozzle rotation shaft.

[0019] As a further embodiment of the present invention: the elastic telescopic component includes a guide cylinder fixed to the slider and a telescopic rod slidably fitted with the guide cylinder. A cylindrical spring is also provided inside the guide cylinder, and one end of the cylindrical spring is connected to the inner wall of the guide cylinder, and the other end is connected to the telescopic rod. A ball bearing is also provided at the end of the telescopic rod away from the slider.

[0020] The ball bearing cooperates with a limiting member disposed on the horizontal platform. The limiting member is arc-shaped and concentric with the arc-shaped member.

[0021] As a further embodiment of the present invention: the transmission structure includes a toothed plate fixedly connected to the telescopic rod and a gear fixed to the rotating shaft of the nozzle, wherein the toothed plate meshes with the gear.

[0022] A fuselage de-icing method, employing the aforementioned vehicle-mounted pneumatic unidirectional jet de-icing device, includes the following steps:

[0023] Step 1: Check the stability of the connection between the base and the vehicle roof, and test the mobility of the telescopic boom assembly;

[0024] Step 2: Move the vehicle to the work position and control the telescopic boom assembly to move the nozzle to the work position;

[0025] Step 3: The swing mechanism operates, driving the nozzle to swing back and forth at the first working point.

[0026] Step four: The power mechanism drives the nozzle to move to the second working point, and the deflection drive mechanism drives the nozzle to change its orientation.

[0027] Step 5: Use nozzles to blow the ice layer at the first and second working points until the ice layer slides off automatically.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This application uses an inclined nozzle, and a first working point and a second working point of the nozzle are formed on the horizontal platform. When the nozzle works at the first working point and the second working point, it can reduce the connection area between the ice layer and the machine body on that side. Thus, it can weaken the connection strength between the ice layer and the machine body from both sides. Finally, as the connection area between the ice layer and the machine body decreases, the ice layer will automatically slide off due to gravity, thus achieving the purpose of de-icing.

[0030] The de-icing principle of this application is to reduce the connection area between the ice layer and the machine body on both sides, gradually weakening the connection strength between the ice layer and the machine body. When the connection strength between the ice layer and the machine body can no longer bear the weight of the ice layer, the ice layer is forced to slide off automatically. Therefore, during operation, the airflow does not need to cover the entire ice layer to achieve the de-icing effect. On the one hand, it can effectively reduce the time spent on de-icing operations and improve efficiency. On the other hand, the nozzle only needs to operate at two points, avoiding the omissions caused by the full coverage of the ice layer, which would lead to incomplete de-icing and leave safety hazards.

[0042] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0044] Please see Figures 1-10 In this embodiment of the invention, a vehicle-mounted pneumatic unidirectional jet de-icing device includes a base 1 mounted on a vehicle, and further includes:

[0045] The telescopic arm assembly is connected to the base 1. The end of the telescopic arm assembly away from the base 1 is connected to the cross platform 7, and the cross platform 7 is inclinedly provided with a nozzle 14 for spraying high-speed airflow. The telescopic arm assembly can move relative to the base 1 to change the orientation of the nozzle 14.

[0046] The mounting base 11 is slidably mounted on the horizontal platform 7, and the nozzle 14 is movably mounted on the mounting base 11. The horizontal platform 7 is provided with a slide rail 701 to guide the mounting base 11. The two ends of the slide rail 701 are the first working point and the second working point of the nozzle 14, respectively. The nozzle 14 can be driven by a power mechanism mounted on the horizontal platform 7 to move back and forth between the first working point and the second working point. Specifically, the mounting base 11 is slidably fitted into the horizontal platform 7 through the slide rail 701.

[0047] In detail, an assembly box 8 is fixedly installed on the cross platform 7. The power mechanism includes a first lead screw rotatably installed in the assembly box 8 and a movable block 9 slidably installed in the assembly box 8 and threadedly connected to the first lead screw. A first motor is also installed in the assembly box 8. The output end of the first motor is connected to the first lead screw. The movable block 9 is fixed to the assembly base 11 through a connecting arm 10. The side of the assembly box 8 is also provided with a strip groove for the connecting arm 10 to move.

[0048] When it is necessary to change the working position of the nozzle 14, the first motor drives the first lead screw to rotate, and the movable block 9 slides within the assembly box 8 through threaded engagement with the first lead screw. Correspondingly, the movable block 9 can drive the assembly seat 11 to slide along the slide rail 701 through the connecting arm 10, so that the nozzle 14 can be switched from the first working position to the second working position or from the second working position to the first working position.

[0049] A swing mechanism is provided on the mounting base 11 and connected to the nozzle 14. The swing mechanism is used to drive the nozzle 14 to swing back and forth at the first working point and the second working point. The nozzle 14 is also connected to a deflection drive mechanism. When the nozzle 14 reaches the second working point, the deflection drive mechanism is triggered, which can cause the nozzle 14 to perform a deflection action so as to change the orientation of the nozzle 14.

[0050] It should be further explained that, in actual operation, the horizontal platform 7 will be equipped with an air supply end connected to the nozzle 14. Specifically, the air supply end is equipped with an air pump, which can blow high-speed airflow onto the ice layer on the machine body through the nozzle 14 to melt the ice layer.

[0051] Preferably, in order to increase the melting rate of the ice layer, a heating wire can be installed at the outlet of the air pump to heat the airflow, so that the airflow blown towards the ice layer has a certain temperature and improves the de-icing efficiency.

[0052] In detail, during operation, the base 1 is stably fixed on the top of the vehicle. When the vehicle moves to a suitable working position, the telescopic boom moves relative to the base 1 and the vehicle until the nozzle 14 can face the ice surface and is in a suitable working position.

[0053] With attachment Figure 2 Taking the state shown as an example, initially, the nozzle 14 is at the first working point and the nozzle 14 is tilted towards the center of the horizontal platform 7. The swing mechanism moves, driving the nozzle 14 to swing back and forth. Thus, the high-speed airflow blown by the nozzle 14 can gradually melt the ice layer. Since the nozzle 14 is in a tilted state, the high-speed airflow is not perpendicular to the ice layer. The high-speed airflow is in a slanted blowing form, which makes the connection area between the ice layer on the side of the first working point and the machine body gradually decrease.

[0054] After the first work point is completed, the mounting base 11 slides along the slide rail 701 on the horizontal platform 7 to the second work point. During this process, the deflection drive mechanism is triggered in the latter part of the stroke of the nozzle 14, causing the nozzle 14 to perform a deflection action. As a result, the nozzle 14 changes its orientation and can continue to deflect towards the center side of the horizontal platform 7. Subsequently, the nozzle 14 continues to spray ice, thereby reducing the connection area between the ice layer on the side of the second work point and the machine body.

[0055] Furthermore, this application uses an inclined nozzle 14, and a first working point and a second working point of the nozzle 14 are formed on the cross platform 7. When the nozzle 14 works at the first working point and the second working point, it can reduce the connection area between the ice layer and the machine body on that side. Thus, it can weaken the connection strength between the ice layer and the machine body from both sides. Finally, as the connection area between the ice layer and the machine body decreases, the ice layer will automatically slide off due to gravity, achieving the purpose of de-icing.

[0056] In response, the de-icing principle of this application is to reduce the connection area between the ice layer and the fuselage on both sides, gradually weakening the connection strength between the ice layer and the fuselage. When the connection strength between the ice layer and the fuselage can no longer bear the weight of the ice layer, the ice layer is forced to slide off automatically. Therefore, during operation, the airflow does not need to cover the entire ice layer to achieve the de-icing effect. On the one hand, it can effectively reduce the time spent on de-icing operations and improve efficiency. On the other hand, the nozzle 14 only needs to operate at two points, avoiding the omissions caused by the full coverage of the ice layer, which would lead to incomplete de-icing and leave safety hazards.

[0057] Please refer to it again. Figure 1 and Figure 6 The telescopic boom assembly includes a first long arm 2 rotatably mounted on the base 1 and a second long arm 3 slidably fitted with the first long arm 2. A first hydraulic cylinder 4 is rotatably mounted on the base 1, and the movable end of the first hydraulic cylinder 4 is hinged to the first long arm 2.

[0058] A second hydraulic cylinder 5 is provided on the first long arm 2. The movable end of the second hydraulic cylinder 5 is fixed to the second long arm 3. The cross platform 7 is rotatably installed on the end of the second long arm 3 away from the base 1. A third hydraulic cylinder 6 is rotatably installed on the second long arm 3. The movable end of the third hydraulic cylinder 6 is hinged to the cross platform 7.

[0059] In actual operation, the first hydraulic cylinder 4 operates, driving the first long arm 2 and the second long arm 3 to rotate relative to the base 1. Simultaneously, in coordination with the action of the second hydraulic cylinder 5, the second hydraulic cylinder 5 can drive the second long arm 3 to move towards the outside or inside of the first long arm 2. Furthermore, under the drive of the third hydraulic cylinder 6, the cross platform 7 can deflect relative to the second long arm 3. Therefore, before the formal de-icing operation, through the coordinated work of the first hydraulic cylinder 4, the second hydraulic cylinder 5, and the third hydraulic cylinder 6, the nozzle 14 can be adjusted to a suitable working position, maintaining a suitable distance and positional relationship between the nozzle 14 and the ice layer on the machine body, so as to facilitate the de-icing operation.

[0060] Please refer to it again. Figure 5 , Figure 9 as well as Figure 10 The swing mechanism includes a guide structure disposed on the mounting base 11 and a reciprocating movable component connected to the guide structure. The guide structure is connected to the nozzle 14, and the reciprocating movable component is movable on the mounting base 11 in a direction perpendicular to the slide rail 701. The guide structure includes an arc-shaped member 12 fixedly mounted on the mounting base 11. The arc-shaped member 12 is provided with a guide groove 1201, and a slider 13 is slidably fitted in the guide groove 1201. The nozzle 14 is rotatably mounted on the slider 13, and the axial direction of the rotation axis of the nozzle 14 is perpendicular to the slide rail 701. The reciprocating movable component is connected to the slider 13, and the deflection drive mechanism is mounted on the side of the slider 13 and connected to the rotation axis of the nozzle 14.

[0061] Furthermore, since aircraft fuselages typically have a curved shape, this application provides the aforementioned arc-shaped component 12. By sliding and engaging the slider 13 on the arc-shaped component 12, the reciprocating oscillating motion of the nozzle 14 is guided. Specifically, when the reciprocating component moves, it can drive the slider 13 to slide reciprocally within the guide groove 1201. Thus, the movement trajectory of the nozzle 14 can adapt to the curved shape of the aircraft fuselage. This allows the nozzle 14 to improve the consistency of the degree of spraying at each spraying point when spraying ice at the first and second working points, which is beneficial for the subsequent automatic sliding of the ice due to the reduced contact area between the sides and the fuselage.

[0062] The reciprocating moving component includes a guide rail 15 disposed on the mounting base 11 and a drive block 16 slidably fitted on the guide rail 15. The drive block 16 is connected to a threaded drive structure disposed on the mounting base 11. The side of the slider 13 is rotatably connected to a first follower arm 17 via a shaft 1301. The side of the drive block 16 is provided with a second follower arm 18. The first follower arm 17 and the second follower arm 18 are slidably connected. The side of the arc-shaped component 12 is also provided with an arc-shaped through groove 1202 for the shaft 1301 to move.

[0063] In detail, the threaded drive structure includes a second lead screw rotatably mounted on the mounting base 11, the second lead screw passing through the drive block 16, and the drive block 16 being threadedly connected to the second lead screw. A second motor is also mounted on the mounting base 11, and the output end of the second motor is connected to the second lead screw.

[0064] When the nozzle 14 is located at the first working point or the second working point, the second motor drives the second lead screw to rotate in the forward or reverse direction. Correspondingly, the guide rail 15 guides the drive block 16, and the drive block 16 is threadedly engaged with the second lead screw, so that the drive block 16 slides back and forth along the guide rail 15. The drive block 16 drives the slider 13 to slide in the guide groove 1201 through the second follower arm 18 and the first follower arm 17, and the slider 13 rotates relative to the first follower arm 17, and the first follower arm 17 slides relative to the second follower arm 18.

[0065] Please refer to it again. Figures 7-10 The deflection drive mechanism includes an elastic telescopic component located on the side of the slider 13 and two sets of transmission structures connected to the elastic telescopic component. The two sets of transmission structures are respectively connected to both ends of the rotating shaft of the nozzle 14. The elastic telescopic component includes a guide cylinder 19 fixed to the slider 13 and a telescopic rod 20 slidably fitted with the guide cylinder 19. A cylindrical spring is also provided inside the guide cylinder 19, with one end of the cylindrical spring connected to the inner wall of the guide cylinder 19 and the other end connected to the telescopic rod 20. A ball bearing 2001 is also provided at the end of the telescopic rod 20 away from the slider 13. The ball bearing 2001 cooperates with a limiting member 23 provided on the horizontal platform 7. The limiting member 23 is arc-shaped and concentric with the arc-shaped member 12.

[0066] It should be further noted that two elongated protrusions are fixedly provided on the outer wall of the telescopic rod 20, and two elongated grooves adapted to the elongated protrusions are provided on the inner wall of the guide cylinder 19. The elongated protrusions and elongated grooves are arranged along the axial direction of the guide cylinder 19 and the telescopic rod 20, thereby providing guidance for the relative sliding of the telescopic rod 20 and the guide cylinder 19, and ensuring the accuracy of the transmission structure in transmitting the rotation shaft of the nozzle 14.

[0067] The transmission structure includes a toothed plate 21 fixedly connected to the telescopic rod 20 and a gear 22 fixed to the rotating shaft of the nozzle 14, and the toothed plate 21 meshes with the gear 22.

[0068] With attachment Figure 2 With appendix Figure 8 Taking the state shown as an example, at this time, the nozzle 14 is located at the first working point, the telescopic rod 20 is in a naturally extended state, and the limiting member 23 is located on one side of the second working point.

[0069] When the nozzle 14 moves from the first working point to the second working point, the ball bearing 2001 will contact the limiting member 23 during the latter part of the stroke. As the mounting base 11 continues to move, the telescopic rod 20 will slide relative to the guide cylinder 19, the cylindrical spring will be compressed, and the toothed plate 21 and the gear 22 will be positioned relative to each other. As a result, the toothed plate 21 and the gear 22 mesh, and the gear 22 rotates, causing the nozzle 14 to change its orientation after reaching the second working point. When the nozzle 14 is working at the second working point, since the limiting member 23 and the arc-shaped member 12 are concentric, the ball bearing 2001 will roll back and forth on the limiting member 23.

[0070] During the initial stroke of the nozzle 14 as it moves from the second working point to the first working point, the cylindrical spring rebounds, and the telescopic rod 20 and the guide cylinder 19 slide relative to each other again, causing the nozzle 14 to deflect in the opposite direction. Therefore, the nozzle 14 has different orientations when it is at the first working point and the second working point.

[0071] As another embodiment of the present invention, a fuselage de-icing method is also proposed, which employs the aforementioned vehicle-mounted pneumatic unidirectional jet de-icing device, and includes the following steps:

[0072] Step 1: Check the stability of the connection between base 1 and the top of the vehicle, and test the mobility of the telescopic boom assembly;

[0073] Step 2: Move the vehicle to the working position and control the telescopic boom assembly to move the nozzle 14 to the working position;

[0074] Step 3: The swing mechanism operates, driving the nozzle 14 to swing back and forth at the first working point.

[0075] Step four: The power mechanism drives the nozzle 14 to move to the second working position, and the deflection drive mechanism drives the nozzle 14 to change its orientation.

[0076] Step 5: Use nozzles 14 to spray the ice layer at the first and second working points until the ice layer automatically slides off.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
