Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a bomb-throwing device for a fire-fighting bomb-throwing UAV. Background Technology

[0002] In fire rescue operations, the rapid and effective delivery of fire extinguishing bombs or agents is crucial for controlling the fire. Firefighting bomb-dropping drones are specialized equipment designed for fighting fires at high altitudes or in complex terrain. They carry fire extinguishing bombs and drop them on target areas to quickly reduce the fire's intensity and minimize personnel risk. Compared to traditional ground-based firefighting methods, firefighting bomb-dropping drones offer advantages such as high mobility, rapid response, and adaptability to complex environments, making them particularly suitable for high-rise building fires, forest fires, and inaccessible fire sites. To achieve precise delivery, firefighting bomb-dropping drones are typically equipped with specialized throwing devices to ensure the fire extinguishing bombs are dropped at designated locations, improving firefighting efficiency.

[0003] Existing fire-fighting bomb-dropping drones primarily employ mechanical clamping, sliding rail release, or electromagnetic adsorption for deployment. For instance, some devices use mechanical claws or clamping mechanisms to secure the fire extinguishing bombs, releasing them upon deployment. Others utilize sliding rails or chutes, allowing the bombs to slide down under gravity. However, existing deployment devices often involve a single, one-time deployment, making timely adjustments difficult when deviations occur, thus reducing the efficiency of firefighting operations. Therefore, this paper proposes a new deployment device for fire-fighting bomb-dropping drones to address these issues. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a throwing device for a fire-fighting bomb-throwing drone, which aims to improve the problem that existing technologies often involve one-time throwing and it is difficult to make timely adjustments when there is a throwing deviation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A throwing device for a fire-fighting bomb-throwing drone includes a drone body. A throwing mechanism is connected to the bottom of the drone body via an installation mechanism. The throwing mechanism includes a magazine, with a magazine cover fixedly connected to the top. The magazine contains a cross-shaped lever that divides the magazine into four storage chambers. A rotating shaft is coaxially fixedly connected to the top of the lever, passing through the magazine cover and rotatably engaging with it. A slotted plate is fixedly connected to the upper end of the rotating shaft, and four radially extending slots are evenly spaced along the circumference of the slotted plate. A [missing information - likely a device or mechanism] is fixedly installed on the magazine cover. The motor has a rotating plate fixedly connected to its output end, and a connecting plate fixedly connected to the top of the rotating plate. The end of the connecting plate away from the rotating plate has a vertical column adapted to the opening slot. The bottom plate of the ammunition magazine has a drop hole located below one of the ammunition storage chambers. When the motor drives the rotating plate and the connecting plate to rotate continuously, the vertical column inserts into one of the opening slots and pushes the slot plate to rotate 90 degrees before disengaging, thereby driving the lever to rotate intermittently so that the fire extinguishing ammunition in the ammunition storage chamber moves to the position of the drop hole and falls.

[0007] As a further description of the above technical solution:

[0008] The cover is fixedly connected to a cartridge for storing fire extinguishing shells. The bottom of the cartridge is connected to the storage chamber inside the magazine. The height of the magazine cavity is adapted to the size of a fire extinguishing shell.

[0009] As a further description of the above technical solution:

[0010] The lever plate has a through-hole for each ammunition storage chamber, the through-hole is adapted to the size of a single fire extinguishing ammunition, and the ammunition tube, the through-hole and the drop hole are arranged coaxially along the vertical axis.

[0011] As a further description of the above technical solution:

[0012] The installation mechanism includes a fixed column fixedly connected to the UAV body and a connecting column fixedly connected to the missile magazine. The fixed column and the connecting column correspond one-to-one. The top of the connecting column is provided with a threaded groove. The side wall of the fixed column is rotatably fitted with a threaded cap. The internal thread of the threaded cap is adapted to the threaded groove. The fixed column and the connecting column are fixedly connected by tightening the threaded cap and the threaded groove.

[0013] As a further description of the above technical solution: a plug is provided at the top of the connecting column, and a socket adapted to the plug is provided at the bottom of the fixing column. The plug is inserted into the socket to achieve the positioning of the connecting column and the fixing column.

[0014] As a further description of the above technical solution:

[0015] The side wall of the ammunition magazine is fixedly connected to a side plate, and the bottom of the connecting column is fixedly connected to the side plate.

[0016] As a further description of the above technical solution: multiple anti-slip strips are fixedly connected to the side wall of the threaded cap, and the anti-slip strips are evenly distributed along the circumference of the threaded cap.

[0017] As a further description of the above technical solution: the installation structure is arranged in a rectangular array between the ammunition magazine and the UAV body to enhance the installation stability of the delivery mechanism.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the rotating plate is driven by the starting motor, which causes the slot plate to drive the deflector plate to rotate intermittently. As the rotation proceeds, when the ammunition inside the magazine moves above the drop hole, the ammunition falls downward, thereby achieving intermittent delivery. This avoids the problem of uneven target coverage caused by the simultaneous delivery of multiple ammunition, and improves the accuracy and continuity of delivery. The transmission mechanism is simple and does not require complex gear sets or sensor control, thus reducing the failure rate.

[0020] 2. In this utility model, the plug at the top of the connecting column is inserted into the fixed column, and then the threaded cap is slid down and twisted to make it twist through the threaded groove to the top of the connecting column, thus connecting the fixed column and the connecting column, thereby completing the installation of the delivery mechanism. Through the cooperation between the above structures, the ammunition magazine and the UAV body can be quickly disassembled and assembled, which is convenient for changing the ammunition magazine in the fire scene. At the same time, through the modular design, the equipment can be installed with delivery mechanisms of different specifications to adapt to different types of fire extinguishing bombs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 One embodiment of this utility model is a throwing device for a fire-fighting bomb-throwing drone, which includes a drone body 1. A throwing mechanism is provided at the bottom of the drone body 1. The throwing mechanism is connected to the frame of the drone body 1 through an installation mechanism. The installation structure is arranged in a rectangular array to make the installation of the throwing mechanism more stable.

[0029] The delivery mechanism includes a magazine 2, with a magazine cover 6 fixedly connected to the top of the magazine 2. Inside the magazine 2, a cross-shaped lever 4 divides the magazine 2 into four storage chambers. A rotating shaft 3 is coaxially fixedly connected to the top of the lever 4, passing through the magazine cover 6 and rotating in cooperation with it. A slotted plate 7 is fixedly connected to the upper end of the rotating shaft 3, with four radially extending slots evenly spaced around its circumference. A motor 8 is fixedly mounted on the magazine cover 6, with a rotating plate 9 fixedly connected to the output end of the motor 8. A connecting plate 1 is fixedly connected to the top of the rotating plate 9. 0. The end of the connecting plate 10 away from the rotating plate 9 is provided with a vertical column that is adapted to the opening slot; the bottom plate of the ammunition compartment 2 is provided with a drop hole 12, which is located below one of the ammunition storage chambers; when the motor 8 drives the rotating plate 9 and the connecting plate 10 to rotate continuously, the vertical column is inserted into one of the opening slots and pushes the slot plate 7 to rotate 90 degrees and then disengage. The slot plate 7 rotates 1 / 4 turn after the rotating plate 9 rotates one turn, thereby driving the lever 4 to rotate intermittently so that the fire extinguishing ammunition in the ammunition storage chamber moves to the position of the drop hole 12 and falls.

[0030] A cartridge 11 for storing fire extinguishing shells is fixedly connected to the magazine cover 6. The bottom of the cartridge 11 communicates with the storage chamber inside the magazine 2. The height of the inner cavity of the magazine 2 is adapted to the size of a single fire extinguishing shell. A lever 4 has a through-hole 5 corresponding to each storage chamber. The through-hole 5 is adapted to the size of a single fire extinguishing shell, and the cartridge 11, the through-hole 5, and the drop hole 12 are arranged coaxially along the vertical axis. The cartridge 11 can automatically fill the storage chamber with a fire extinguishing shell. When the ammunition inside the storage chamber moves above the drop hole 12, the ammunition will fall downwards.

[0031] Reference Figure 1 and Figure 4 The installation mechanism includes a fixed post 17 fixedly connected to the UAV body 1 and a connecting post 14 fixedly connected to the ammunition magazine 2, with each fixed post 17 corresponding to the other. A side plate 13 is fixedly connected to the side wall of the ammunition magazine 2, and the bottom of the connecting post 14 is fixedly connected to the side plate 13. A plug 15 is provided at the top of the connecting post 14, and a socket adapted to the plug 15 is provided at the bottom of the fixed post 17. The plug 15 is inserted into the socket to position the connecting post 14 and the fixed post 17. A threaded groove 16 is provided at the top of the connecting post 14, and a threaded cap 18 is rotatably fitted onto the side wall of the fixed post 17. The internal thread of the threaded cap 18 is adapted to the threaded groove 16. The fixed connection between the fixed post 17 and the connecting post 14 is achieved by tightening the threaded cap 18 and locking it in place with the threaded groove 16. Multiple anti-slip strips 19 are evenly distributed circumferentially on the side wall of the threaded cap 18, facilitating the twisting of the threaded cap 18.

[0032] Working principle: When installing the delivery mechanism, first insert the plug 15 at the top of the connecting column 14 into the insertion hole at the bottom of the fixing column 17, then slide the threaded cap 18 downwards and twist it through the threaded groove 16 to the top of the connecting column 14, connecting the fixing column 17 and the connecting column 14, thus completing the installation of the delivery mechanism. When the equipment is in use, the drone body 1 is hovered above the fire point. The fire extinguishing bullet at the bottom inside the ammunition canister 11 will fall into the ammunition chamber 2. Then, the motor 8 is started to drive the rotating plate 9 to rotate. After the rotating plate 9 rotates one revolution, the slot plate 7 rotates 1 / 4 revolution under the action of the connecting plate 10. After the bottom fire extinguishing bullet enters the ammunition chamber 2, the fire extinguishing bullet above will move downwards. With the rotation of the lever 4, the fire extinguishing bullet will enter the ammunition chamber 2 through the concave hole 5. As the rotation continues, when the ammunition inside the ammunition chamber 2 moves above the drop hole 12, the ammunition will fall downwards, achieving the effect of intermittent delivery and improving the accuracy and continuity of delivery.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
