Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV with a carrying mechanism. Background Technology

[0002] As a typical example of the integration of modern aviation and intelligent equipment, unmanned aerial vehicles (UAVs) achieve efficient and flexible mission execution through aerial platforms and can carry diverse payloads according to specific needs. They have been widely used in many fields, including agricultural plant protection, pesticide spraying and seeding, logistics and distribution, power line inspection, disaster relief, and forest fire and pest control and monitoring. In the field of fire emergency response and disaster prevention, fire extinguishing bombs are mounted on UAVs and dropped above the fire source to extinguish it. In existing technologies, an electric hook is installed on the bottom of the UAV, and the hook for attaching the fire extinguishing bomb is attached to the UAV hook. After reaching the appropriate position, the hook is opened to release the fire extinguishing bomb. However, this hook-attachment method is prone to instability during UAV flight. When the UAV accelerates, decelerates, or turns, the fire extinguishing bomb sways due to inertia, affecting the stability of the UAV's flight. Therefore, a UAV with a mounting mechanism is proposed that can stably carry and release fire extinguishing devices, thus solving the problem of the fire extinguishing device's swaying affecting the UAV's flight. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a drone with a mounting mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A drone with a mounting mechanism includes a drone body, a fixed base at the bottom of the drone body, a mounting plate at the bottom of the fixed base, and a fire extinguishing bomb below the mounting plate;

[0006] The mounting plate is provided with sliding grooves, and four sliding grooves are symmetrically arranged on the center line of the mounting plate;

[0007] A slider is slidably provided in the groove. The slider is I-shaped, and its upper and lower ends are in contact with the upper and lower ends of the mounting plate, respectively.

[0008] The mounting plate is equipped with a drive assembly for driving the slider to slide within the groove;

[0009] The bottom of the slider is connected to a clamping plate, which is a telescopic structure, and a support block is provided at the bottom of the clamping plate. The clamping plate and the support block form an L-shape.

[0010] Two opposing sliders are provided with hanging rods, which are staggered in the horizontal direction.

[0011] Furthermore, the drive assembly includes a connecting plate, which is rotatably positioned at the center of the top of the mounting plate. The four corners of the connecting plate are rotatably connected to connecting rods, and the other end of the connecting rods is rotatably connected to the top of the slider. The connecting rods are L-shaped.

[0012] A bidirectional cylinder is fixedly mounted on the fixed base. Both output ends of the bidirectional cylinder are connected to drive blocks, and the two drive blocks are respectively connected to two sliders at opposite positions.

[0013] Furthermore, the clamping plate includes a fixed rod and a movable rod. The fixed rod is connected to the bottom of the slider, and a movable groove is provided at the bottom of the fixed rod. The upper end of the movable rod is slidably disposed in the movable groove, and the support block is connected to the bottom of the movable rod.

[0014] An adjustment groove is provided on one side of the fixed rod, and the adjustment groove is connected to the moving groove;

[0015] One side of the moving rod is threaded with an adjusting nut, and one end of the adjusting nut is slidably disposed in the adjusting groove.

[0016] Furthermore, a limiting groove is provided on one side of the fixed rod in a linear array, and the limiting groove is located on both sides of the adjustment groove and communicates with the adjustment groove;

[0017] The adjusting nut is T-shaped and its protruding end engages with the limiting groove.

[0018] Furthermore, the fixing rod has an arc-shaped structure on the side near the fire extinguishing bomb.

[0019] Furthermore, one side of the curved surface of the fixing rod is provided with anti-slip texture.

[0020] Furthermore, one of the hanging rods has a slot on the side near the other hanging rod; the other hanging rod has a corresponding insert on its side.

[0021] When the two hanging rods are close together, the plug is inserted into the corresponding slot.

[0022] Furthermore, the bottom of the mounting plate is provided with a limiting frame, and two limiting frames are symmetrically arranged on both sides of the hanging ring of the fire extinguishing bomb;

[0023] The two hanging rods can pass through the interior of the limiting frame when they move.

[0024] This utility model has the following beneficial effects:

[0025] 1. Attach the hanging ring of the fire extinguishing bomb to one of the hanging rods. Then, the drive assembly moves the four sliders synchronously closer to the fire extinguishing bomb. The sides of the two hanging rods contact each other to form a sealing frame. The hanging ring of the fire extinguishing bomb slides on the two hanging rods. One of the clamping plates pushes the fire extinguishing bomb to the middle position of the mounting plate. The four clamping plates clamp the sides of the fire extinguishing bomb and the support block supports the bottom of the fire extinguishing bomb, thereby stably clamping the fire extinguishing bomb and ensuring that it will not shake when the drone is flying.

[0026] 2. By synchronously extending and retracting both ends of the bidirectional cylinder, the slider connected to the drive block moves. The movement of the slider causes the connecting rod to rotate, which in turn drives the connecting plate to rotate, thereby driving the other two connecting rods to rotate and the other two sliders to move. This achieves synchronous movement of the four sliders, which in turn drives the clamping plate to clamp the fire extinguishing bomb. Attached Figure Description

[0043] like Figure 1-4As shown, a drone with a carrying mechanism includes a drone body 1, which is existing technology and includes a support frame and a propeller driven by a drive motor. It can carry items for transportation. The specific structure is not described in detail in this case. The drone body 1 has a fixed base 2 at its bottom, and a mounting plate 3 at the bottom of the fixed base 2. The upper surface of the mounting plate 3 is square, and four grooves 31 are symmetrically arranged on the center line of the mounting plate 3, that is, at the center line of the four sides of the mounting plate 3 and extending through the bottom of the mounting plate 3. A slider 32 slides within the grooves 31. The slider 32 is I-shaped, and its upper and lower ends contact the upper and lower surfaces of the mounting plate 3, respectively. The middle position of the slider 32 slides within the grooves 31, allowing the slider to... For more stable movement, the mounting plate 3 is equipped with a drive assembly 4, which drives the four sliders 32 to slide synchronously in the corresponding grooves 31. A fire extinguishing bomb 9 is located below the mounting plate 3. The bottom of the sliders 32 is connected to a clamping plate 5. The four clamping plates 5 are used to clamp the sides of the fire extinguishing bomb 9. The clamping plates 5 are telescopic structures and their length can be adjusted according to the model of the fire extinguishing bomb 9. The bottom of the clamping plate 5 is equipped with a support block 6. The clamping plate 5 and the support block 6 form an L-shape. The support block 6 supports the bottom of the fire extinguishing bomb 9. Two opposing sliders 32 are equipped with hanging rods 7, which are located on opposite sides of the two sliders 32. The two hanging rods 7 are staggered in the horizontal direction, and when the two hanging rods 7 are close together, their opposite sides are in contact. The hanging rods 7 are used to hang the hanging ring 91 of the fire extinguishing bomb 9. Before use, adjust the length of the clamping plate 5 according to the model of the fire extinguishing bomb 9 to be mounted. Hang the hanging ring 91 of the fire extinguishing bomb 9 on one of the hanging rods 7. Then, the drive component 4 drives the four sliders 32 to move synchronously closer to the fire extinguishing bomb 9. The two hanging rods 7 first overlap in the horizontal direction, and the sides of the two hanging rods 7 contact each other to form a sealing frame. As the movement continues, the hanging ring 91 of the fire extinguishing bomb 9 slides on the two hanging rods 7. One of the clamping plates 5 pushes the fire extinguishing bomb 9 to the middle position of the mounting plate 3. The four clamping plates 5 clamp the sides of the fire extinguishing bomb 9 and the support block 6 supports the bottom of the fire extinguishing bomb 9, thereby stably clamping the fire extinguishing bomb 9 and ensuring that the drone will not shake when flying. After flying to the corresponding position, the drive component 4 drives the slider 32 to move in the direction, and the two hanging rods 7 also separate, so that the fire extinguishing bomb 9 can fall to extinguish the fire.

[0044] Preferably, the drive assembly 4 includes a connecting plate 41, which is square and rotatably positioned at the center of the top of the mounting plate 3. The four corners of the connecting plate 41 are rotatably connected to the connecting rods 42, and the other end of the connecting rods 42 is rotatably connected to the top of the sliders 32. The connecting rods 42 are L-shaped. A bidirectional cylinder 43 is fixedly mounted on the fixed base 2. Both output ends of the bidirectional cylinder 43 are connected to drive blocks 44. The two drive blocks 44 are respectively connected to two sliders 32 in opposite positions. By synchronously extending and retracting both ends of the bidirectional cylinder 43, the sliders 32 connected to the drive blocks 44 are moved. The movement of the sliders 32 causes the connecting rods 42 to rotate, which drives the connecting plate 41 to rotate, thereby driving the other two connecting rods 42 to rotate and driving the other two sliders 32 to move. This achieves synchronous movement of the four sliders 32. The bidirectional cylinder 43 can reduce the vibration of the fixed base 2 and have less impact on the flight of the UAV body 1.

[0045] Preferably, the clamping plate 5 includes a fixed rod 51 and a movable rod 52. The fixed rod 51 is connected to the bottom of the slider 32. The side of the fixed rod 51 near the fire extinguishing bomb 9 has an arc-shaped structure. One side of the arc-shaped surface of the fixed rod 51 is provided with anti-slip texture. A movable groove 53 is opened at the bottom of the fixed rod 51. The upper end of the movable rod 52 is slidably disposed in the movable groove 53. The support block 6 is connected to the bottom of the movable rod 52. An adjustment groove 54 is opened on one side of the fixed rod 51. The adjustment groove 54 is connected to the movable groove 53. An adjustment nut 55 is threadedly connected to one side of the movable rod 52. One end of the adjustment nut 55 is slidably disposed in the adjustment groove 54. A limiting groove 56 is linearly arrayed on one side of the fixed rod 51. The limiting groove 56 is disposed on both sides of the adjustment groove 54 and is connected to the adjustment groove 54. The adjusting nut 55 is T-shaped and the protruding end of the adjusting nut 55 is engaged with the limiting groove 56. The moving rod 52 and the fixed rod 51 are fixed by turning the adjusting nut 55, and the adjusting nut 55 is engaged with the limiting groove 56, which further improves the stability of the moving rod 52 and the fixed rod 51 and prevents the moving rod 52 from sliding due to insufficient tightness of the adjusting groove 54 when the adjusting nut 55 is loose.

[0046] Preferably, one of the hanging rods 7 has a slot 71 on the side near the other hanging rod 7; the other hanging rod 7 has a corresponding insert 72 on its side; when the two hanging rods 7 are close together, the insert 72 and the slot 71 are inserted into each other. The bottom of the mounting plate 3 has a limiting frame 73, and the two limiting frames 73 are symmetrically arranged on both sides of the hanging ring 91 of the fire extinguishing bomb 9; the two hanging rods 7 can pass through the inside of the limiting frame 73 when they move. Before use, the four sliders 32 are driven to move so that the two hanging rods 7 pass through the limiting frame 73 but the two hanging rods 7 do not contact each other and do not form a sealed frame shape. Then, the hanging ring 91 of the fire extinguishing bomb 9 is hung on one of the hanging rods 7 and is located between the two limiting frames 73. Then the fire extinguishing bomb 9 is clamped. When the fire extinguishing bomb 9 is released, the two hanging rods 7 move in opposite directions. If the fire extinguishing bomb 9 is hung on one of the hanging rods 7, it will be blocked by the limiting frame 73 when it passes through the limiting frame 73. When the hanging rod 7 is completely moved out of the limiting frame 73, the hanging ring 91 is disengaged from the hanging rod 7 and can fall.

[0047] The working principle of this utility model is as follows: Before use, adjust the length of the clamping plate 5 according to the model of the fire extinguishing bomb 9 to be mounted. Tighten the adjusting nut 55 so that the protruding end of the adjusting nut 55 moves out of the limiting groove 56. Then, drive the moving rod 52 to slide in the moving groove 53 to adjust the length. Then tighten the adjusting nut 55 so that the output end of the adjusting nut 55 is inserted into the corresponding limiting groove 56. First, drive the four sliders 32 to move so that both hanging rods 7 pass through the limiting frame 73 but the two hanging rods 7 do not contact each other. Hang the hanging ring 91 of the fire extinguishing bomb 9 on one of the hanging rods 7. Then, drive the drive assembly 4 to drive the four sliders 32 to move synchronously. Approaching the fire extinguishing bomb 9, the sides of the two hanging rods 7 contact each other to form a sealing frame shape, and the insert block 72 is inserted into the slot 71. The hanging ring 91 of the fire extinguishing bomb 9 slides on the two hanging rods 7. One of the clamping plates 5 pushes the fire extinguishing bomb 9 to the middle position of the mounting plate 3. The four clamping plates 5 clamp the sides of the fire extinguishing bomb 9 and the support block 6 supports the bottom of the fire extinguishing bomb 9, thereby stably clamping the fire extinguishing bomb 9 and ensuring that the drone will not shake when flying. After flying to the corresponding position, the drive component 4 drives the slider 32 to move in the direction, the two hanging rods 7 also separate, and under the blocking action of the limit frame 73, the fire extinguishing bomb 9 can fall to extinguish the fire.

[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
