Description

Technical Field

[0001] This utility model relates to the field of firefighting drone technology, and more specifically, to a throwing-type firefighting drone. Background Technology

[0002] With the continuous development of drone technology, drones are increasingly being applied to fire protection systems. Currently, Chinese Patent Publication No. CN120114787A discloses a fire-fighting drone. This drone includes a main body, a water tank fixedly mounted at the bottom, a mounting plate fixedly mounted on the water tank, and a water nozzle fixedly mounted on the outer surface of the water tank. The water nozzle works in conjunction with the water tank. The water tank has a water storage chamber inside and a spraying assembly inside, which works in conjunction with the water nozzle. A camera body is slidably mounted on the mounting plate for spraying... The components include a flexible hose running through the inside of a water tank, with a pressure pump fixedly inserted at one end of the hose inside the tank, an air pump fixedly installed at the bottom of the outer surface of the water tank, and a first bend pipe inserted at the output end of the air pump. A ring pipe is fixedly fitted on the outer surface of the water gun nozzle, and a spray nozzle is opened inside the water gun nozzle. A flexible hose is fixedly inserted on the pressure pump. When this fire-fighting drone is in use, it extinguishes fires by spraying water. However, the drone itself has a limited payload, and it can only carry a small amount of fire-fighting water at a time, resulting in poor fire-extinguishing effect and limited fire-fighting capacity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a throwable fire-fighting drone, which extinguishes fires by throwing fire extinguishing bombs, and has the advantages of good fire extinguishing effect and rapid fire extinguishing.

[0004] This utility model provides a throwable firefighting drone, including a drone body and a controller connected to the drone body; the throwable firefighting drone also includes a storage compartment, the upper end of which is fixed to the bottom of the drone body; the inner side of the storage compartment is provided with several storage cavities arranged in an array and open at the bottom, each storage cavity is used to store several vertically arranged fire extinguishing bombs; an electrically controlled limiting component is fixed on the outer wall of the storage compartment, corresponding to each of the several storage cavities, the limiting component is electrically connected to the controller, each limiting component is used to prevent several fire extinguishing bombs in the corresponding storage cavity from falling freely from the storage cavity, and during fire extinguishing, each limiting component is used to control the several fire extinguishing bombs in the corresponding storage cavity to fall one by one.

[0005] By adopting the above-mentioned structure, this utility model extinguishes fires by throwing fire extinguishing bombs, thus having the advantages of better fire extinguishing effect and faster fire extinguishing compared with traditional fire-fighting drones that use water spraying.

[0006] In one possible implementation, each limiting component includes several servos vertically spaced and fixed to the outer wall of the storage compartment. The number of servos in each limiting component is the same as the number of fire extinguishing bombs in the corresponding storage compartment. Each servo has a baffle fixed to its output end. The side wall of the storage compartment has through holes corresponding to each baffle for the baffle to enter or exit the storage compartment. Each baffle is used to abut against the lower edge of the fire extinguishing bomb at the corresponding position to prevent the fire extinguishing bomb from falling freely from the storage compartment. Each servo is electrically connected to the controller. In this embodiment, each storage compartment is used to store two fire extinguishing bombs distributed vertically, and correspondingly, the number of servos in each limiting component is also two. By using this limiting component, the UAV body and the storage compartment are first inverted, and the controller controls the servos to rotate the baffles. To allow the baffle to exit the storage chamber, two fire extinguishing bombs are inserted into each storage chamber. The controller then controls the servo motor to drive the free end of the baffle into the storage chamber. The drone body and storage compartment are then uprighted, so that the storage compartment is at the bottom of the drone body. Due to the baffle, each fire extinguishing bomb is blocked in its corresponding storage chamber. When the ground control personnel operate the fire-fighting drone to drop the fire extinguishing bombs, firstly, the lower servo motor in each limiting assembly drives the corresponding baffle to exit the storage chamber. At this time, the lower fire extinguishing bomb can fall from the storage chamber to the fire source to extinguish the fire. After the lower fire extinguishing bomb falls, the upper servo motor drives the corresponding baffle to exit the storage chamber. At this time, the upper fire extinguishing bomb can fall from the storage chamber to the fire source to extinguish the fire.

[0007] In one possible implementation, the lower end of the storage compartment is provided with a flared section that expands outward from top to bottom. The inner sidewall of the upper end of the flared section forms a conical surface at the junction with the lower end of each storage cavity. The conical surface is used to guide the fire extinguishing bomb by engaging with the outer wall of the fire extinguishing bomb so that the fire extinguishing bomb can be inserted into the storage cavity. With the flared section, when the fire-fighting drone is on standby, the storage compartment can be supported on the ground by the flared section. Since the flared section expands outward from top to bottom, the fire-fighting drone can be reliably and stably supported on the ground. Furthermore, since the inner sidewall of the upper end of the flared section forms a conical surface at the junction with the lower end of each storage cavity, the outer wall of the fire extinguishing bomb can engage with the conical surface to guide the fire extinguishing bomb into the storage cavity during the insertion process, which facilitates the loading of the fire extinguishing bomb.

[0008] In one possible implementation, a number of connecting columns arranged in an array are provided between the storage compartment and the drone body. The upper end of each connecting column is fixed to the bottom of the drone body, and the lower end of each connecting column is fixed to the upper end of the storage compartment. With this structure, the storage compartment can be reliably fixed to the bottom of the drone body by the action of the connecting columns. Attached Figure Description

[0013] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] See Figure 1-4As shown in the figure, this application discloses a throwable firefighting drone, including a drone body 1 and a controller connected to the drone body 1; the throwable firefighting drone also includes a storage compartment 2, the upper end of which is fixed to the bottom of the drone body 1; the inner side of the storage compartment 2 is provided with a plurality of storage cavities 21 arranged in an array and open at the lower end, each storage cavity 21 is used to store a plurality of fire extinguishing bombs arranged vertically; an electrically controlled limiting component is fixed on the outer wall of the storage compartment 2, corresponding one-to-one with the plurality of storage cavities 21, the limiting component is electrically connected to the controller, each limiting component is used to prevent the plurality of fire extinguishing bombs in the corresponding storage cavity 21 from falling freely from the storage cavity 21, and during fire extinguishing, each limiting component is used to control the plurality of fire extinguishing bombs in the corresponding storage cavity 21 to fall one by one.

[0015] Each limiting component includes several servo motors 3 vertically spaced and fixed to the outer wall of the storage compartment 2. The number of servo motors 3 in each limiting component is the same as the number of fire extinguishing bombs in the corresponding storage cavity 21. Each servo motor 3 has a baffle 4 fixed to its output end. The side wall of the storage cavity 21 is provided with through holes 22 corresponding to each baffle 4 for allowing the baffle 4 to enter or exit the storage cavity 21. Each baffle 4 is used to abut against the lower edge of the corresponding fire extinguishing bomb to prevent the fire extinguishing bomb from falling freely from the storage cavity 21. Each servo motor 3 is electrically connected to the controller. In this embodiment, each storage cavity is used to store two fire extinguishing bombs distributed vertically. Correspondingly, the number of servo motors in each limiting component is also two. By using this limiting component, the UAV body and the storage compartment are first inverted, and the controller controls the servo motors to drive the baffles. The blades rotate to disengage the baffles from the storage chambers. Two fire extinguishing bombs are then inserted into each storage chamber. The controller then controls the servo motors to guide the free ends of the baffles into the storage chambers. The drone body and storage chamber are then uprighted, ensuring the storage chamber is located at the bottom of the drone body. Due to the baffles, each fire extinguishing bomb is blocked in its corresponding storage chamber. When the ground control personnel operate the fire-fighting drone to drop fire extinguishing bombs, firstly, the lower servo motor in each limiting assembly drives the corresponding baffle to disengage from the storage chamber. At this point, the lower fire extinguishing bomb falls from the storage chamber to the fire source to extinguish the fire. After the lower fire extinguishing bomb falls, the upper servo motor drives the corresponding baffle to disengage from the storage chamber. At this point, the upper fire extinguishing bomb falls from the storage chamber to the fire source to extinguish the fire.

[0016] The lower end of the storage compartment 2 is provided with a flared section 23 that expands outward from top to bottom. The inner sidewall of the upper end of the flared section 23 forms a conical surface 24 at the junction with the lower end of each storage cavity 21. The conical surface 24 is used to guide the fire extinguishing bomb by cooperating with the outer wall of the fire extinguishing bomb so that the fire extinguishing bomb can be inserted into the storage cavity 21. With the flared section, when the fire-fighting drone is on standby, the storage compartment can be supported on the ground by the flared section. Since the flared section expands outward from top to bottom, the fire-fighting drone can be reliably and stably supported on the ground. Moreover, since the inner sidewall of the upper end of the flared section forms a conical surface at the junction with the lower end of each storage cavity, the outer wall of the fire extinguishing bomb can cooperate with the conical surface to guide the fire extinguishing bomb into the storage cavity during the process of inserting the fire extinguishing bomb into the storage cavity, which can facilitate the loading of the fire extinguishing bomb.

[0017] Several connecting columns 5 arranged in an array are provided between the storage compartment 2 and the drone body 1. The upper end of each connecting column 5 is fixed to the bottom of the drone body 1, and the lower end of each connecting column 5 is fixed to the upper end of the storage compartment 2. With this structure, the storage compartment can be reliably fixed to the bottom of the drone body under the action of several connecting columns.

[0018] When using this invention, fire extinguishing bombs are first loaded into each storage cavity, and the fire extinguishing bombs in each storage cavity are limited by a limiting component. When a fire occurs, the ground flight controller controls the fire-fighting drone to fly above the fire source. Then, the ground flight controller wirelessly controls the controller on the drone body via remote control, so that the controller controls the limiting component to release the obstruction of the fire extinguishing bombs in the storage cavity. Subsequently, the fire extinguishing bombs in the storage cavity can fall from the storage cavity and extinguish the fire source. The aforementioned fire extinguishing bombs are existing products on the market. When they come into contact with the fire source, they can automatically explode and extinguish the fire.

[0019] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
