Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a throwing device for UAVs. Background Technology

[0002] In today's society, with the acceleration of urbanization, urban buildings are becoming increasingly dense and taller. At the same time, the vast areas of natural regions such as forests and grasslands are significantly increasing the frequency and complexity of fire accidents. Drones, with their high mobility and rapid response, are widely used in firefighting. Drones can quickly reach the fire scene and drop fire extinguishing bombs, effectively controlling the fire and keeping firefighters away from dangerous areas, ensuring their safety.

[0003] Currently, drones typically carry multiple fire extinguishing bombs when performing firefighting missions. These bombs are deployed using a throwing mechanism. However, in existing technologies, each throwing mechanism generally requires a separate drive source, which not only increases space occupation and operating costs but also raises the risk of malfunctions. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a throwing device for unmanned aerial vehicles (UAVs).

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drone-mounted throwing device includes: a drone body; brackets mounted on both sides of the bottom of the drone body; a base plate mounted between the two brackets; four storage bins coaxially arrayed on the bottom of the base plate; bin lids hinged to the bottom of each storage bin; and insertion holes formed on the side of each bin lid away from its hinge. A fixing block is mounted on the outer surface of each storage bin facing its array axis; and a plug rod is mounted on the fixing block via an elastic mechanism to engage with the insertion hole. The elastic mechanism applies a force to the plug rod in the direction of the insertion hole. An unlocking mechanism is provided between the four storage bins, which pulls the four plug rods out of the insertion holes.

[0006] The beneficial effects of this utility model are as follows: the elastic mechanism allows the insert rods to be stably inserted into the insertion holes, and the lid is fixed to the bottom of the storage bucket to support the fire extinguishing bombs. When the unlocking mechanism drives the four insert rods to be pulled out of the insertion holes, the lid automatically opens under the action of gravity and the fire extinguishing bombs fall down, thereby achieving the purpose of throwing four fire extinguishing bombs with one drive source. This not only reduces space occupation and usage costs, but also reduces the risk of failure due to the single drive source.

[0007] Furthermore, the elastic mechanism includes a guide post mounted on the outer surface of the fixed block, with an end cap installed at one end. A wedge-shaped sliding plate is slidably mounted on the outer surface of the guide post, and an insertion rod is installed at one end of the wedge-shaped sliding plate, sliding through the interior of the fixed block. A spring is sleeved on the outer surface of the guide post, with both ends of the spring abutting against the end cap and the wedge-shaped sliding plate, respectively. The spring pushes the insertion rod into the insertion hole, thus securing the lid.

[0008] Furthermore, the unlocking mechanism includes a mounting plate installed between the four storage bins. A servo electric cylinder is mounted on the bottom of the mounting plate, and a disc is mounted on the telescopic end of the servo electric cylinder. Four wedge-shaped compression rods are coaxially arrayed on the upper surface of the disc, with each of the four wedge-shaped compression rods corresponding vertically to one of the four wedge-shaped sliding plates. The servo electric cylinder drives the wedge-shaped compression rods and the bottom of the wedge-shaped sliding plates to apply thrust, which can drive the insertion rod to be pulled out of the insertion hole, achieving the purpose of throwing.

[0009] Furthermore, the four wedge-shaped compression rods are progressively taller, with the highest and second-highest rods symmetrically distributed along the axis of the disk. This allows the four fire extinguishing bombs to be launched diagonally, reducing the degree of center of gravity shift and improving the stability of the drone.

[0010] Furthermore, a guide rod is connected to the bottom of the disc, which slides through to the bottom of the mounting plate. This guide rod limits the movement of the disc, preventing lateral forces from damaging the servo electric cylinder.

[0011] Furthermore, the storage container includes a cylinder and a door. One side of the door is hinged to the cylinder, and the other side of the door is fixedly connected to the cylinder by connecting bolts. This facilitates the loading of fire extinguishing bombs into the cylinder.

[0012] Furthermore, the wedge-shaped slide has evenly distributed ball bearings inside, which roll in contact with the outer surface of the guide post. This allows the wedge-shaped slide to smoothly and effortlessly pull the insert rod out of the insertion hole to complete the throwing operation. Attached Figure Description

[0020] Example 1 Figure 1 This utility model provides a structural diagram of a throwing device for a drone. Figure 2 This is a schematic diagram of the substrate structure in this utility model. Figure 3 This is a cross-sectional structural diagram of the storage container in this utility model. Figure 1 , Figure 2 and Figure 3As shown, the device includes: a drone body 1; brackets 101 are mounted on both sides of the bottom of the drone body 1; a base plate 102 is mounted between the two brackets 101; four storage bins 2 are coaxially arrayed on the bottom of the base plate 102; a lid 3 is hinged to the bottom of the storage bin 2; and an insertion hole 301 is provided on the side of the lid 3 away from its hinge. A fixing block 4 is mounted on the outer surface of the storage bin 2 facing its array axis; an insertion rod 401 that engages with the insertion hole 301 is mounted on the fixing block 4 via an elastic mechanism 5; the elastic mechanism 5 applies a force to the insertion rod 401 in the direction of the insertion hole 301. An unlocking mechanism 6 is provided between the four storage bins 2; the unlocking mechanism 6 is used to pull the four insertion rods 401 out of the insertion hole 301.

[0021] In use, the fire extinguishing bomb is placed into the storage container 2, and the lid 3 is closed to the storage container 2. The elastic mechanism 5 applies elastic force to the insertion rod 401, making the insertion rod 401 stably inserted into the insertion hole 301. The lid 3 is then fixed to the bottom of the storage container 2, thus completing the loading of the fire extinguishing bomb. When the drone body 1 carrying the fire extinguishing bomb flies to above the fire, the unlocking mechanism 6 drives the four insertion rods 401 to be pulled out of the insertion hole 301. Under the action of gravity, the lid 3 automatically opens and the fire extinguishing bomb falls, thus achieving the purpose of throwing four fire extinguishing bombs with one drive source. This not only reduces space occupation and usage costs, but also reduces the risk of malfunction due to the single drive source.

[0022] Figure 4 for Figure 3 An enlarged diagram of A in the diagram. Figure 6 This is a schematic diagram of the unlocking mechanism in this utility model. Figure 4 and Figure 6 As shown, the elastic mechanism 5 includes a guide post 501 mounted on the outer surface of the fixed block 4. An end cap 502 is mounted at the end of the guide post 501. A wedge-shaped sliding plate 503 is slidably mounted on the outer surface of the guide post 501, and an insertion rod 401 is mounted at one end of the wedge-shaped sliding plate 503, sliding through the interior of the fixed block 4. A spring 504 is sleeved on the outer surface of the guide post 501, with both ends of the spring 504 abutting against the end cap 502 and the wedge-shaped sliding plate 503, respectively. The unlocking mechanism 6 includes a mounting plate 601 mounted between the four storage bins 2. A servo electric cylinder 602 is mounted at the bottom of the mounting plate 601. A disc 603 is mounted at the end of the telescopic end of the servo electric cylinder 602. Four wedge-shaped compression rods 604 are coaxially arrayed on the upper surface of the disc 603, with the four wedge-shaped compression rods 604 corresponding one-to-one with the vertical positions of the four wedge-shaped sliding plates 503.

[0023] When the lid 3 is fixed to the bottom of the storage bucket 2, the wedge-shaped slide plate 503 is first slid on the guide post 501 and the spring 504 is compressed, which causes the insertion rod 401 to retract. Then, after the lid 3 is closed, the wedge-shaped slide plate 503 is released. At this time, the compressed spring 504 releases its elasticity and pushes the wedge-shaped slide plate 503 to reset. The wedge-shaped slide plate 503 drives the insertion rod 401 to automatically insert into the insertion hole 301, thereby fixing the lid 3.

[0024] When the servo electric cylinder 602 pushes the disc 603 upward, the disc 603 drives the wedge-shaped extrusion rod 604 and the bottom of the wedge-shaped slide plate 503 to apply a thrust. Under the action of the inclined plane, the wedge-shaped slide plate 503 is driven to slide on the guide post 501, and the insertion rod 401 is pulled out from the insertion hole 301. At this time, the barrel cover 3 is released from fixation, and the fire extinguishing bomb falls under the action of gravity, achieving the purpose of throwing.

[0025] Figure 4 for Figure 3 An enlarged diagram of A in the diagram. Figure 6 This is a schematic diagram of the unlocking mechanism in this utility model. Figure 4 and Figure 6 As shown, a guide rod 605 is connected to the bottom of the disc 603, and the guide rod 605 slides through to the bottom of the mounting plate 601. Rolling balls are evenly distributed inside the wedge-shaped slide plate 503, and these balls roll in contact with the outer surface of the guide post 501.

[0026] The guide rod 605 limits the movement of the disc 603, preventing lateral forces from damaging the servo electric cylinder 602 and extending its service life. The ball bearings reduce the resistance of the wedge-shaped slide plate 503 sliding on the guide post 501, allowing it to smoothly and effortlessly pull the insertion rod 401 out of the insertion hole 301 under the action of the wedge-shaped compression rod 604 to complete the throwing operation.

[0027] Example 2 Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 6 As shown, the height of the four wedge-shaped extrusion rods 604 increases sequentially, and the highest and second highest wedge-shaped extrusion rods 604 are symmetrically distributed along the axis of the disk 603.

[0028] First, since the four wedge-shaped compression rods 604 are at different heights, the four fire extinguishing bombs can be thrown in sequence to extinguish different fire points and increase the fire extinguishing range.

[0029] Secondly, the combustion of fire sources releases a large amount of heat, raising the temperature of the surrounding air. According to the principle of thermal expansion and contraction, the hot air expands in volume and decreases in density, thus generating upward buoyancy. This buoyancy drives the hot air upward, forming an upward airflow. When the drone body 1 drops the fire extinguishing bombs, it is directly above the airflow. After dropping the fire extinguishing bombs, the overall center of gravity shifts. Under the combined effect of the airflow and the shift in the center of gravity, the drone body 1 may fall. Therefore, by symmetrically distributing the highest and second highest wedge-shaped compression rods 604 along the axis of the disk 603, the four fire extinguishing bombs can be dropped in a diagonal sequence, thereby reducing the degree of shift in the center of gravity and improving the stability of the drone body 1.

[0030] Example 3 Based on Embodiment 2, the present invention can be further improved in the following ways, such as... Figure 5 As shown, the storage bucket 2 includes a cylinder 201 and a bucket door 202. One side of the bucket door 202 is hinged to the cylinder 201, and the other side of the bucket door 202 is fixedly connected to the cylinder 201 by connecting bolts 203.

[0031] After unscrewing the connecting bolt 203, the barrel door 202 can be opened, making it convenient to load fire extinguishing bombs into the cylinder 201. After loading the fire extinguishing bombs, the barrel door 202 is closed and secured again. When the fire extinguishing bombs are thrown, the inner walls of the cylinder 201 and the barrel door 202 can act as limiting guides, ensuring that the fire extinguishing bombs are vertically downward and improving the throwing accuracy.
