Description

Technical Field

[0001] This utility model relates to the field of drone firefighting equipment technology, and in particular to a drone-borne dry powder fire extinguishing bomb precision delivery device. Background Technology

[0002] In the field of fire fighting, the remote deployment of fire extinguishing bombs by drones has become an important means of dealing with complex scenarios such as high-rise fires and forest fires.

[0003] However, existing UAV-borne fire extinguishing bomb delivery devices mostly use a fixed mounting structure, which cannot flexibly adjust the delivery angle and limiting accuracy. When the fire extinguishing bombs are delivered, they are easily affected by airflow, resulting in problems such as deviation in landing point and jamming of the delivery channel, which leads to a decrease in fire extinguishing efficiency and makes it difficult to accurately target the core area of ​​the fire. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low accuracy in the existing technology due to the fixed launching angle and insufficient limiting precision of fire extinguishing bombs, and to propose a drone-borne dry powder fire extinguishing bomb precision launching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drone-borne dry powder fire extinguishing bomb precision delivery device, comprising a positioning frame and a guiding frame, wherein a triangular piece is fixedly installed at one end of the positioning frame, and a connecting plate is fixedly installed on one side of the end of the guiding frame, the triangular piece being rotatably connected to the connecting plate, and a support roller being rotatably installed at both ends of the guiding frame, wherein a positioning piece is fixedly installed on one side of the positioning frame and one side of the guiding frame, and a first electric cylinder is rotatably connected between the two positioning pieces, the first electric cylinder being close to the other end of the positioning frame.

[0006] Preferably, extension plates are fixedly installed on both sides of the middle section of the guide frame, and the two extension plates are arranged symmetrically.

[0007] Preferably, a guide tube is fixedly installed on one side of the extension plate, and the guide tube is perpendicular to the guide frame.

[0008] Preferably, a limiting frame is inserted inside the guide tube, and the limiting frame is located on one side of the guide frame.

[0009] Preferably, a second electric cylinder is fixedly connected to the other end of the limiting frame, and the second electric cylinder is fixedly mounted on another extension plate.

[0010] Preferably, bearing seats are fixedly installed at both ends of the positioning frame, and the central shaft of the support roller is rotatably installed inside the bearing seats.

[0011] Preferably, the guide frame and the limiting frame form a frame structure, and the fire extinguishing bomb is disposed between the guide frame and the limiting frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotational connection structure between the positioning frame and the guide frame, in conjunction with the first electric cylinder drive, enables flexible adjustment of the deployment angle. By adjusting the angle and extending the guide path, the movement path of the fire extinguishing bomb can counteract the resistance of the airflow. Combined with the drag reduction design of the support roller, the accuracy of the dry powder fire extinguishing bomb deployment is effectively improved, ensuring that the fire extinguishing bomb can accurately act on the core area of ​​the fire.

[0013] 2. In this utility model, an adjustable limiting mechanism is formed by an extension plate, a guide tube, a limiting frame and a second electric cylinder. The clamping space can be flexibly adjusted according to the size of the fire extinguishing bomb, which not only ensures the stability during transportation, but also allows for quick release to avoid jamming. At the same time, it is compatible with different specifications of fire extinguishing bombs, improving the versatility and reliability of the device. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a UAV-borne dry powder fire extinguishing bomb precision delivery device, including a positioning frame 1 and a guide frame 4. A triangular piece 8 is fixedly installed at one end of the positioning frame 1, and a connecting plate 9 is fixedly installed on one side of the end of the guide frame 4. The triangular piece 8 and the connecting plate 9 are rotatably connected. Support rollers 5 are rotatably installed at both ends of the guide frame 4. Positioning pieces 2 are fixedly installed on one side of the positioning frame 1 and one side of the guide frame 4. A first electric cylinder 3 is rotatably connected between the two positioning pieces 2. The first electric cylinder 3 is close to the other end of the positioning frame 1. Bearing seats 12 are fixedly installed at both ends of the positioning frame 1. The central shaft of the support roller 5 is rotatably installed inside the bearing seat 12.

[0019] The specific settings and functions of this embodiment are described below. The positioning frame 1 serves as the core mounting base and is fixed to the drone body. The triangular piece 8 at its end forms a rotating connection structure with the connecting plate 9 on one side of the guide frame 4, providing a fulcrum for adjusting the angle of the guide frame 4. The extension and retraction of the first electric cylinder 3 can drive the guide frame 4 to flexibly rotate around the connection between the triangular piece 8 and the connecting plate 9, achieving precise control of the deployment angle. The presence of the positioning piece 2 provides sufficient space for the first electric cylinder 3 to ensure that the guide frame 4 can rotate to a vertical state. The bearing seat 12 provides a stable mounting base for the support roller 5. When dropping the bomb, the support roller 5 can effectively reduce friction. The deployment angle of the guide frame 4 can be flexibly adjusted according to the fire location and height, solving the deployment deviation problem caused by the fixed angle of traditional devices, and greatly improving the accuracy of the fire extinguishing bomb landing point. When the fire extinguishing bomb is deployed, it contacts the support roller 5, and rolling friction replaces sliding friction, significantly reducing deployment resistance, avoiding fire extinguishing bomb jamming, and ensuring a smooth and efficient deployment process. This not only improves the accuracy and stability of fire extinguishing bomb deployment but also adapts to the needs of different fire scenarios, effectively improving fire extinguishing efficiency.

[0020] Example 2: Figure 1 and Figure 2As shown, extension plates 6 are fixedly installed on both sides of the middle section of the guide frame 4. The two extension plates 6 are arranged symmetrically. A guide tube 10 is fixedly installed on one side of the extension plate 6. The guide tube 10 is perpendicular to the guide frame 4. A limiting frame 7 is inserted into the inside of the guide tube 10. The limiting frame 7 is located on one side of the guide frame 4. A second electric cylinder 11 is fixedly connected to the other end of the limiting frame 7. The second electric cylinder 11 is fixedly installed on another extension plate 6. The guide frame 4 and the limiting frame 7 form a frame structure. The fire extinguishing bomb is placed between the guide frame 4 and the limiting frame 7.

[0021] The overall effect of this embodiment is as follows: the extension plate 6 serves as a supporting structure to determine the position of the guide tube 10; the limiting frame 7 is inserted into the guide tube 10, and its other end is connected to the second electric cylinder 11; the extension and retraction of the second electric cylinder 11 can drive the limiting frame 7 to slide along the guide tube 10, so that the guide frame 4 and the limiting frame 7 form an adjustable frame structure, and the fire extinguishing bomb is confined within this frame space; the symmetrical arrangement of the extension plate 6 ensures structural balance and provides a stable installation base for the guide tube 10 and the second electric cylinder 11; the guide tube 10 guides the limiting frame 7, ensuring its smooth and accurate movement; the second electric cylinder 11 drives the limiting frame 7 to adjust its position, which can accommodate fire extinguishing bombs of different sizes; the frame structure securely holds the fire extinguishing bomb, preventing shaking during transportation; and it quickly retracts and releases during deployment, solving the jamming problem.

[0022] The usage and working principle of this device are as follows: First, the positioning frame 1 is fixedly installed to the drone body. The fire extinguishing bomb is attached to the side of the guide frame 4 and is limited by the limiting frame 7. When fixing the fire extinguishing bomb, the limiting frame 7 is driven to slide along the guide tube 10 by controlling the second electric cylinder 11, so that the limiting frame 7 fixes the fire extinguishing bomb. Then, the drone is controlled to fly to the target fire area. According to the specific location and height of the fire, the first electric cylinder 3 is controlled to extend and retract, driving the guide frame 4 to rotate around the connection between the triangular piece 8 and the connecting plate 9, adjusting to a suitable release angle. Finally, the piston rod of the second electric cylinder 11 is controlled to extend, driving the limiting frame 7 to leave the fire extinguishing bomb. The fire extinguishing bomb slides down the support rollers 5 at both ends of the guide frame 4 under the action of gravity to complete the release.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way.
