Abstract
Description
Technical Field
[0001] The invention belongs to the field of unmanned aerial vehicle storage, and in particular relates to a detachable fixed-wing unmanned aerial vehicle parking cabin. Background Art
[0002] In recent years, domestic drone technology has continued to mature, the industry has developed rapidly, and drones have played an important role in various fields such as electricity, communications, security, and environmental protection. According to the flight platform configuration, it can be divided into rotary-wing drones, fixed-wing drones, paraglider drones, flapping-wing drones, etc., among which rotary-wing and fixed-wing drones are more commonly used. Fixed-wing drones require the use of runways, catapults or hand throws for assisted takeoff. Rotary-wing drones have short battery life and small load capacity, so they are relatively limited in industrial applications. Vertical-takeoff fixed-wing drones have the advantages of both, with large load capacity, long flight time, long cruising distance, strong wind resistance, one-button takeoff, and are not restricted by the geographical environment. They are currently widely used in various industries such as aerial surveying and mapping, oil pipeline inspections, and police reconnaissance.
[0003] During the outdoor inspection of fixed-wing drones, in order to facilitate the charging and maintenance of drones, improve the efficiency of inspection work, and reduce the input of operators, multiple drone parking cabins can be placed in the inspection area to store and charge drones. Unmanned drone parking cabins are generally composed of door structures, centering mechanisms, lifting mechanisms, autonomous charging and power-off structures, etc. At present, the storage objects of the parking cabins on the market are mostly multi-rotor drones, and there are few parking cabins for large wingspans such as fixed-wing drones. The pitot tube is an extremely important measurement tool in the fixed-wing drone system. The measured static pressure and dynamic pressure or total pressure values can directly reflect the flight status of the drone, which plays a very important role in the safe flight of the drone. According to the flight characteristics, fixed-wing UAVs have greater wind resistance during flight and need to adjust the landing direction according to the wind direction when landing. Unlike rotary-wing UAVs, which maintain the same landing direction every time, fixed-wing UAVs generally have a longer wingspan. If the cabin structure design is based on the traditional rotary-wing UAV, the cabin dimensions will be relatively large, while the width of a standard van is generally 1.8m, 2.1m, or 2.2m, making the fixed-wing UAV cabin difficult to transport.
[0004] Invention patent CN108502201 A discloses a hangar including a helipad and an automatic charging device. The parking cabin realizes the landing positioning of the UAV through the movement of the lateral support rod and the longitudinal guide rod. The helipad landing plate needs to have two long grooves, and it is difficult to ensure its integrity and rigidity requirements. Invention patent CN108502201A discloses a drawer-type UAV hangar, in which the alignment guide device arranged in the middle includes a U-shaped indicator light, a QR code, a circular outline and an I-shaped mark within the circular outline.
[0005] The existing drone parking cabins are small in size and light in weight. They are generally used to store multi-rotor drones. If fixed-wing drones with large wingspans are stored, the size of the parking cabin will be relatively large. In addition, standard vans are of fixed size, making it difficult to transport large-sized parking cabins and thus unable to be widely promoted and applied. The existing drone parking cabins lack airspeed detection systems for fixed-wing drone airspeed tubes, and lack basic guarantees for the safe flight of fixed-wing drones. If operated by operators, this will increase human resources for the entire parking cabin, and the cabin cannot be truly unmanned. Summary of the invention

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0040] like Figure 1-9As shown, a detachable fixed-wing UAV parking cabin comprises a box body 1, a wing shield assembly 5, a UAV storage system 3, a pitot tube detection system 4 and a cabin door 2, wherein the cabin door 2 is slidably covered at the top opening of the box body 1, the wing shield assembly 5 comprises a wing shield upper cover 501 and a wing shield bottom box 502, through holes are symmetrically opened on both sides of the outer wall of the box body 1, the wing shield bottom box 502 is installed on the edges of the through holes on both sides of the box body 1, and the wing shield upper cover 501 is installed on both sides of the cabin door 2, and moves with the opening or closing of the cabin door 2. When the cabin door 2 is closed, the wing shield upper cover 501 overlaps with the wing shield bottom box 502 to form a fixed UAV storage cabin. In order to maintain the supporting effect of the wing shield upper cover 501, a rib plate with supporting effect is arranged on the inner wall of the wing shield upper cover 501. When the staff needs to install the wing shield assembly 5, the wing shield assembly 5 is respectively installed on the edge of the through hole of the cabin door 2 and the box body 1 by bolts, and the UAV lands on the UAV parking platform 302 in the parking cabin. Since the wing shield assemblies 5 protruding from the outside of the box body 1 for placing the wings are arranged on both sides of the parking cabin box body 1, the fixed-wing UAV can be placed in the parking cabin without expanding the capacity of the parking cabin, and it can be compatible with various models of UAVs.
[0041] The inner wall at the bottom of the box body 1 is provided with a wing shield placement slot 503 and a control box 7. The wing shield placement slot 503 is located on one side of the control box. The wing shield placement slot 503 includes two cross beams and two longitudinal beams. The two ends of the two cross beams are respectively fixedly connected to the two ends of the two longitudinal beams to form a rectangular frame structure. The width of the wing shield placement slot 503 is greater than the width of the wing shield bottom box 502. When the parking cabin is used, the wing shield assembly 5 needs to be disassembled. At this time, the disassembled wing shield assembly 5 is placed into the wing in the box body 1. The wing shield placement slot 503 is placed in the wing shield placement slot 503. Since the width of the wing shield placement slot 503 is greater than the width of the wing shield bottom box 502, the wing shield bottom box 502 is first placed in the wing shield placement slot 503. Since the width of the wing shield bottom box 502 is greater than the width of the wing shield upper cover 501, the wing shield upper cover 501 is then placed in the wing shield bottom box 502. The wing shield assembly 5 can be disassembled and stored in the parking cabin. During transportation, the wing shield can be disassembled and stored in the parking cabin, which saves space and is convenient for installation and transportation.
[0042] A plurality of drainage holes are provided at the bottom of the wing shield bottom box 502, which has a good waterproof effect. When outdoor rainwater enters the wing shield bottom box 502, the rainwater is discharged from the wing shield bottom box 502 along the drainage holes because of the drainage holes, so as to prevent the wing shield bottom box 502 from storing rainwater or water entering in other ways from entering the box body 1. The wing shield upper cover 501 and the cabin door 2, and the wing shield bottom box 502 and the box body 1 are fixedly connected by screws respectively. Sealing strips are provided between the wing shield upper cover 501 and the cabin door 2, and between the wing shield bottom box 502 and the box body 1 respectively. The sealing strips are made of rubber or silicone material and have a certain elasticity, so as to further enhance the sealing effect between the wing shield upper cover 501 and the cabin door 2, and between the wing shield bottom box 502 and the box body 1.
[0043] When the staff needs to land the fixed-wing UAV in the parking cabin, first take out the wing shield assembly 5 from the cabin, fix the wing shield upper cover 501 to the cabin door 2 by bolts, and fix the wing shield bottom box 502 to both sides of the box body 1 by bolts. When the fixed-wing UAV lands on the lifting plate, the fixed-wing UAV is placed in the cabin through the lifting mechanism. At the same time, the wing of the fixed-wing UAV is placed just in the wing shield bottom box 502, the cabin door is closed, and the wing shield upper cover 501 and the wing shield bottom box form an overlap.
[0044] The box body 1 is provided with an inner wall and an outer wall, and a layer for placing a pitot detection system 4 is provided between the inner wall and the outer wall of the box body 1. The pitot detection system 4 includes a fan 402, an air duct 403 and an air inlet 404. One end of the air duct 403 is connected to the box body 1, and the other end is connected to the air outlet of the fan 402. The air inlet of the fan 402 faces the outer wall of the box body 1, and a plurality of air inlet holes 404 are provided on the outer wall of the box body 1. The fan 402 is connected to the support frame 406 through a mounting seat 405. The pitot detection system 4 performs a status detection on the pitot of the fixed-wing UAV before flight, reduces the on-site operation of the operator, reduces the flight accident rate of the UAV, enhances the safety flight guarantee, and ensures the safety and reliability of the UAV flight.
[0045] The box body 1 is also provided with a UAV lifting mechanism 301 and a UAV parking platform 302. The driving motor 3011 is fixed on the bottom plate of the box body 1 and is connected to the first commutator 3012 through a coupling. The first commutator 3012 is connected to the first adapter shaft 3013 through two left and right couplings. The first adapter shaft 3013 transmits the motion to the second commutator 3014 through the coupling. The two sides of the second commutator 3014 transmit the motion to the second adapter shaft 3015 through the coupling. The second adapter shaft 3015 is connected to the reducer 3016 through the coupling. The rotation of the four reducers 3016 drives the lead screw 3017 to rotate, thereby causing the UAV parking platform 302 connected to the lead screw nut 3018 to move up and down.
[0046] An environmental sensing system 5 is also provided on the outside of the box body 1, and the environmental sensing system 5 includes a wind speed and direction sensor, a rain sensor, a camera, etc. The rain sensor uses the model QS-1501, and the camera uses the model Hikvision DS-2CD3T47EDWD-L. The wind speed and direction sensor, the rain sensor, and the camera are all fixed on the external equipment support rod, and are used to confirm the external environment of the parking cabin, the parking cabin and the status of the drone.
[0047] The specific working process of the detachable fixed-wing UAV parking cabin of the present invention is as follows:
[0048] (1) Take-off phase S1: The host computer confirms the external environment of the parking cabin, the parking cabin and the status of the drone through the environment sensing system 6. After confirmation, it sends a cabin opening command, the cabin door is opened, and the drone is powered on. The pitot tube detection system works. When the fan does not rotate, the air inside the box 1 does not flow. The pitot tube collects the static pressure of the air inside the tube. When the fan rotates, the fan 402 blows air into the box 1. The air flow outside the parking cabin is sent into the box 1 through the fan and passes through the pitot tube 401. The pitot tube 401 is located in front of the nose of the aircraft. When the air flow rushes into the pitot tube, the sensor for detecting air pressure in the pitot tube will detect the dynamic pressure value of the air flow. The air flow rate is obtained by comparing the difference between the static pressure and the dynamic pressure. When the pitot tube detects that the wind speed of the air passing through is in the range of 5-10m / s, it means that there is no blockage such as ice inside the pitot tube, and the drone is ready for take-off. At this time, the drone lifting mechanism 301 lifts the lifting plate to the highest point, the drone takes off, and the cabin door 2 is closed.
[0049] (2) Standby stage S2: The cabin does not move and the drone operates along the scheduled route;
[0050] (3) Landing stage S3: The host computer first confirms the surrounding environment of the parking cabin, the parking cabin and the drone status through the environmental perception system 6. After confirmation, it sends an execution end task command, the cabin door 2 opens, the drone lands on the drone parking platform 302, and aligns the fixed wings on both sides of the drone with the wing shield assemblies on both sides of the box 1. The drone lifting mechanism 301 and the drone parking platform 302 descend. When the drone parking platform 302 descends to a certain extent, it stops moving, and the cabin door 2 is closed. Since the cabin door is fixedly connected to the wing shield upper cover 501, after the cabin door 2 is closed, the wing shield upper cover 501 and the wing shield bottom box 502 form a lapped structure, and at this time, a closed drone storage environment is formed in the box 1.
[0051] The parking cabin of the present invention can be produced and processed in batches and customized, and can also be promoted to various application occasions such as automobiles, sea, and air relays. Fig.10 For an example of an engine bay application in a car, see Fig.11 As an example of the application of the engine room at sea, the engine room described in the present invention innovatively adopts a split engine room box and adds a pitot tube detection system inside, which effectively improves the transportability of the engine room and the reliability of the drone operation, and has strong market competitiveness in unmanned products.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
