Description

Technical Field

[0001] The utility model relates to the technical field of airborne flame strip spreading, in particular to an airborne flame strip spreading bracket for an unmanned aerial vehicle (UAV). Background Art

[0002] Generally speaking, the equipment required for cloud seeding aircraft can be divided into four categories: meteorological detection equipment, cloud seeding equipment, air-to-ground data transmission equipment, and modification and supporting equipment. Cloud seeding equipment primarily includes airborne pyrotechnics and flare bombs. Each cloud seeding aircraft must be pre-equipped with external pyrotechnics to mount the necessary equipment.

[0003] Most of the existing drone-mounted flame strip spreading brackets are fixed structures, and the airborne flame strip mounting base is installed on the drone through the bracket. This fixing method makes it difficult to adjust the installation form of the airborne flame strip through the airborne flame strip bracket during operation, thereby improving the convenience of using the airborne flame strip. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide an airborne flame strip spreading bracket for a UAV to solve the technical problem that it is difficult to adjust the installation form of the airborne flame strip through the airborne flame strip bracket.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an unmanned aerial vehicle (UAV)-mounted flame strip spreading bracket, comprising a UAV, wherein upper brackets are provided under the wings on both sides of the UAV, one side of the bottom of the upper bracket is rotatably connected to a first connecting rod, and the other side of the bottom of the upper bracket is rotatably connected to a second connecting rod, a lower bracket is provided at the bottom ends of the first connecting rod and the second connecting rod, a first locking mechanism is provided between the lower bracket and the first connecting rod and the second connecting rod, and a spreader is fixedly connected to the bottom of the lower bracket.

[0006] By adopting the above technical solution, the spreader can be flexibly mounted on the UAV through the upper brackets arranged under the wings on both sides of the UAV, and the first connecting rod and the second connecting rod rotatably connected thereto. Due to the rotatable connection between the connecting rod and the upper bracket, the position and angle of the spreader can be easily adjusted to adapt to different spreading needs.

[0007] Furthermore, the first locking mechanism includes a rotating shaft, and mounting grooves are formed on both sides of the rotating shaft.

[0008] By adopting the above technical solution, the rotating shaft serves as the core component of the first locking mechanism, and the mounting groove provided therein provides an installation position for other locking components, making the locking mechanism more compact and stable.

[0009] Furthermore, a connecting plate is rotatably connected to the interior of the installation slot, and one end of the connecting plate is fixedly connected to a pressure plate.

[0010] By adopting the above technical solution, by rotating the connecting plate inside the installation groove, the locking mechanism is provided with greater flexibility and adjustment space, and the connecting plate can rotate freely in the installation groove, which makes it possible to better adapt to the requirements of different angles and positions during the locking process.

[0011] Furthermore, the bottom ends of the first connecting rod and the second connecting rod are both provided with a card slot, and a plurality of the card slots are provided.

[0012] By adopting the above technical solution, by providing multiple slots at the bottom ends of the first connecting rod and the second connecting rod, more locking position options are provided for the locking mechanism. No matter what angle or position the spreader needs to be adjusted to, a suitable slot can be found for locking, thereby greatly improving the flexibility and adaptability of the bracket.

[0013] Furthermore, a pressing arc surface is fixedly connected to one side of the pressing plate, and a clamping block is fixedly connected to the pressing arc surface.

[0014] By adopting the above technical solution, by fixing the compression arc surface on one side of the pressure plate, the pressure plate can better fit the surface of the first connecting rod or the second connecting rod when locking, increasing the contact area and thus improving the stability of the locking.

[0015] Furthermore, the pressing arc surface is adapted to the bottom ends of the first connecting rod and the second connecting rod, and the clamping block is adapted to the clamping slot.

[0016] By adopting the above technical solution, the clamping arc surface is adapted to the bottom ends of the first connecting rod and the second connecting rod, and the clamping arc surface can fit tightly to the bottom ends of the two connecting rods, thereby ensuring tightness and stability during locking.

[0017] Furthermore, auxiliary wings are fixedly connected to both ends of the rotating shaft.

[0018] By adopting the above technical solution, the auxiliary wings fixedly connected at both ends of the rotating shaft provide additional flight stability for the drone. The auxiliary wings can generate lift during flight, which helps to reduce the load of the drone and thus provide better flight control.

[0019] Furthermore, a second locking mechanism is provided between the lower hanger and the first connecting rod and the second connecting rod.

[0020] By adopting the above technical solution and setting up a second locking mechanism, another locking method is provided, so that the device can easily rotate the gear shaft when adjustment is required, thereby improving the convenience of adjustment.

[0021] Furthermore, the second locking mechanism includes a gear shaft, and racks are meshed on both the upper and lower sides of the gear shaft.

[0022] By adopting the above technical solution, the meshing design of the gear shaft and the rack in the second locking mechanism provides precise locking control for the UAV-mounted flame strip spreading bracket. Through the mutual engagement of the gear and the rack, the accuracy and stability of the locking can be ensured, effectively preventing the spreader from shifting or loosening during flight.

[0023] Furthermore, one end of the rack is fixedly connected to the pressing arc surface, and a supporting gear is provided on one side of the rack.

[0024] By adopting the above technical solution, by fixedly connecting one end of the rack to the clamping arc surface, when the rack moves, the clamping arc surface can lock the first connecting rod or the second connecting rod, thereby automatically adjusting the locking state of the second locking mechanism.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The utility model combines stability, adjustability and ease of operation by providing an upper hanger, a first connecting rod, a second connecting rod, a lower hanger and a first locking mechanism, providing an efficient and reliable solution for spreading operations, achieving secure installation and flexible adjustment of the spreader. At the same time, the coordinated use of the auxiliary wings and the locking mechanism simplifies the operation process and improves flight stability and safety, making the UAV's spreading operation more accurate and reliable, and suitable for different spreading needs.

[0027] 2. The utility model provides an auxiliary wing. When the aircraft takes off, the airflow will blow the auxiliary wing, which provides an automatic locking mechanism for the pylon system. The design of the auxiliary wing cleverly utilizes the airflow during flight to achieve a dynamic adaptive locking function. Because the lift distribution of the auxiliary wing is uneven, with greater lift on the front side, the auxiliary wing will deflect around the rotation axis during flight, further driving the outward movement of the connecting plate and the pressure plate, thereby enhancing the locking effect and ensuring that the spreader always remains in a securely locked state.

[0028] 3. The utility model provides another locking method by setting a second locking mechanism, which increases the diversity and redundancy of locking. While improving the stability of the hanger system, it also increases the flexibility and safety of operation. The transmission method is simple and reliable, easy to operate and maintain, and improves the efficiency and reliability of the locking mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Example 1:

[0038] A UAV-mounted flame strip spreading rack, such as Figures 1-4 As shown, it includes a drone 1, and an upper pylon 9 is provided under the wings 2 on both sides of the drone 1. One side of the bottom of the upper pylon 9 is rotatably connected to the first link 3, and the other side of the bottom of the upper pylon 9 is rotatably connected to the second link 4. A lower pylon 5 is provided at the bottom end of the first link 3 and the second link 4, and a first locking mechanism 6 is provided between the lower pylon 5 and the first link 3 and the second link 4. A spreader 10 is fixedly connected to the bottom of the lower pylon 5. Through the upper pylons 9 provided under the wings 2 on both sides of the drone 1 and the first link 3 and the second link 4 rotatably connected thereto, the spreader 10 is flexibly mounted on the drone 1. Due to the rotatable connection between the link and the upper pylon 9, the position and angle of the spreader can be easily adjusted to adapt to different sowing requirements. At the same time, the first locking mechanism 6 provided between the lower pylon 5 and the first link 3 and the second link 4 provides stability and safety for the spreader 10 during flight, and can effectively prevent the spreader from shifting due to flight vibration or airflow, thereby ensuring the accuracy of sowing and the reliability of operation.

[0039] See Figure 2 and Figure 3The first locking mechanism 6 includes a rotating shaft 601, and mounting grooves 602 are provided on both sides of the rotating shaft 601. The rotating shaft 601 serves as the core component of the first locking mechanism 6. The mounting grooves 602 provided therein provide mounting positions for other locking components, making the locking mechanism more compact and stable. At the same time, the opening of the mounting grooves 602 also enables the rotating shaft 601 to better cooperate with other components to improve the locking effect, thereby ensuring the stability and safety of the spreader 10 during the flight of the UAV 1, and providing more reliable protection for the UAV-mounted flame strip spreading operation.

[0040] See Figure 2 and Figure 3 The interior of the mounting groove 602 is rotatably connected to a connecting plate 603, and one end of the connecting plate 603 is fixedly connected to a pressure plate 604. By rotating the connecting plate 603 inside the mounting groove 602, the locking mechanism is provided with greater flexibility and adjustment space. The connecting plate 603 can rotate freely within the mounting groove 602, which makes it possible to better adapt to the requirements of different angles and positions during the locking process. At the same time, the pressure plate 604 fixedly connected at one end of the connecting plate 603 further enhances the locking effect. The pressure plate 604 can fit tightly on the first connecting rod 3 or the second connecting rod 4, and by increasing friction or pressure, ensure that the connecting rod will not move due to vibration or external force during flight, thereby ensuring the stability and safety of the spreader 10.

[0041] See Figure 2 and Figure 3 The bottom ends of the first link 3 and the second link 4 are both provided with a slot 606, and there are multiple slots 606. By providing multiple slots 606 at the bottom ends of the first link 3 and the second link 4, the locking mechanism is provided with more locking position options. No matter what angle or position the spreader 10 needs to be adjusted to, a suitable slot 606 can be found for locking, thereby greatly improving the flexibility and adaptability of the bracket. At the same time, the provision of multiple slots 606 also increases the stability of the locking, because the most suitable slot 606 can be selected for fixing, which not only can adjust the angle, but also can ensure that the spreader 10 will not loosen or shift due to factors such as vibration or airflow during flight.

[0042] See Figure 2 and Figure 3, one side of the pressure plate 604 is fixedly connected with a clamping arc surface 607, and a clamping block 608 is fixedly connected to the clamping arc surface 607. By fixing the clamping arc surface 607 on one side of the pressure plate 604, the pressure plate 604 can better fit the surface of the first connecting rod 3 or the second connecting rod 4 when locking, increasing the contact area, thereby improving the stability of the locking. At the same time, the clamping block 608 fixedly connected on the clamping arc surface 607 can be embedded in the clamping groove 606, further enhancing the locking effect. The cooperation between the clamping block 608 and the clamping groove 606 enables the locking mechanism to remain stable when subjected to external force, effectively preventing the spreader 10 from shifting or falling off, and improving the stability and safety of the UAV airborne flame strip spreading bracket.

[0043] See Figure 2 and Figure 3 The tightening arc surface 607 is adapted to the bottom ends of the first connecting rod 3 and the second connecting rod 4, and the clamping block 608 is adapted to the clamping slot 606. The tightening arc surface 607 is adapted to the bottom ends of the first connecting rod 3 and the second connecting rod 4, and the tightening arc surface 607 can fit tightly to the bottom ends of the two connecting rods, thereby ensuring the tightness and stability during locking. At the same time, the adaptability of the clamping block 608 and the clamping slot 606 enables the clamping block 608 to be accurately embedded in the clamping slot 606, further enhancing the stability of the locking mechanism and improving the stability and safety of the UAV airborne flame strip spreading bracket during use.

[0044] See Figure 2 and Figure 3 The two ends of the rotating shaft 601 are fixedly connected with auxiliary wings 7. The auxiliary wings 7 fixedly connected at both ends of the rotating shaft 601 provide additional flight stability for the UAV 1. The auxiliary wings 7 can generate lift during flight, which helps to reduce the load of the UAV 1 and thus provide better flight control. At the same time, the design of the auxiliary wings 7 also increases the rotational inertia of the rotating shaft 601, so that the locking mechanism can remain stable when subjected to external force and is not easily disturbed, thereby enhancing the stability of the locking mechanism and providing more reliable protection for the UAV-mounted flame strip spreading operation.

[0045] The implementation principle of the present invention is as follows: first, install the spreader 10 on the lower bracket 5 to ensure that it is firmly installed, then mount the upper bracket 9 under the 2 wings, then adjust the angles of the first link 3 and the second link 4 to achieve the required angle and height, then rotate the auxiliary wing 7, the auxiliary wing 7 drives the rotating shaft 601 to rotate, and then drives the connecting plate 603 and the pressure plate 604 to move outward, so that the block 608 on the pressure plate 604 can be inserted into the slot 606, and the first link 3 and the second link 4 are locked in the current position. When the aircraft takes off, the airflow blows the auxiliary wing 7. Since the lift of the auxiliary wing 7 is not uniform, the lift on the front side of the auxiliary wing 7 is larger, causing the auxiliary wing 7 to deflect around the rotating shaft 601, and continue to drive the connecting plate 603 and the pressure plate 604 to move outward, thereby improving the locking effect.

[0046] Example 2:

[0047] See Figure 4 and Figure 5 A second locking mechanism 8 is provided between the lower bracket 5 and the first connecting rod 3 and the second connecting rod 4. By providing the second locking mechanism 8, another locking method is provided, so that the equipment can easily rotate the gear shaft 801 when adjustment is required, thereby improving the convenience of adjustment. At the same time, the connection form of the gear rack is convenient for inspection and maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0048] See Figure 4 and Figure 5 The second locking mechanism 8 includes a gear shaft 801, and racks 802 are engaged on the upper and lower sides of the gear shaft 801. The meshing design of the gear shaft 801 and the rack 802 in the second locking mechanism 8 provides precise locking control for the UAV-mounted flame strip spreading bracket. The mutual engagement of the gear and the rack can ensure the accuracy and stability of the locking, and effectively prevent the spreader 10 from shifting or loosening during flight. At the same time, when the angle or position of the spreader 10 needs to be adjusted, it can be easily unlocked and re-locked in the new position by manually adjusting the angle or position of the spreader 10 by rotating the gear shaft 801, thereby improving the convenience and efficiency of operation.

[0049] See Figure 4 and Figure 5 One end of the rack 802 is fixedly connected to the pressing arc surface 607, and a supporting gear 803 is provided on one side of the rack 802. By fixing one end of the rack 802 to the pressing arc surface 607, when the rack 802 moves, the pressing arc surface 607 can lock the first connecting rod 3 or the second connecting rod 4, thereby automatically adjusting the locking state of the second locking mechanism 8. At the same time, the supporting gear 803 provided on one side of the rack 802 provides stable support for the rack 802, ensuring that the rack 802 can maintain a stable and accurate meshing state during the movement, thereby improving the locking effect and reliability of the UAV-mounted flame strip spreading bracket.

[0050] The implementation principle of the present invention is as follows: first, the second locking mechanism 8 uses the transmission mechanism of the gear shaft 801 and the rack 802 to drive the connecting plate 603 and the pressure plate 604 to move outward, and the supporting gear 803 can provide additional supporting force to reduce the sliding resistance of the rack 802.
