Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting drones, and particularly to a fire-fighting drone capable of switching fire-extinguishing media. Background Art

[0002] With the development of technology, drone technology has become increasingly mature. Drones are widely used due to their fast speed and flexible operation, and are introduced into the field of fire-fighting. Fire extinguishing is achieved by using drones to carry and drop fire-extinguishing bombs at the fire scene.

[0003] Chinese Patent Publication No. CN118289207B discloses a fire-fighting drone for fire-fighting, including a fuselage. A first support plate is connected below the fuselage. The first support plate is horizontally arranged. Opposite sides of the lower surface of the first support plate are fixedly connected with second support plates. The second support plates are perpendicular to the first support plate. A bomb-dropping box is rotatably connected between the two second support plates. A rotating assembly for driving the bomb-dropping box to flip up and down is arranged at the second support plate. An ejection port is opened on one side wall of the bomb-dropping box. An ejection assembly for ejecting the fire-extinguishing bomb towards the ejection port is arranged in the bomb-dropping box.

[0004] In this existing design, although the bomb-dropping box can be driven to rotate by the rotating assembly, so that the fire-extinguishing bomb can fly obliquely upward or downward, thereby improving the applicability of the fire-fighting drone. Through the guiding action of the first guiding plate and the second guiding plate on the fire-extinguishing bomb, it is ensured that multiple fire-extinguishing bombs are not easily confused during movement. Through the setting of the second closing door, it is ensured that the fire-extinguishing bomb is not easily removed from the bomb-dropping box when the fire-extinguishing bomb does not need to be launched.

[0032] In order to more clearly understand the above - mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0034] Embodiment 1

[0035] In the prior art, an existing fire - fighting unmanned aerial vehicle includes an airframe 1. A first support plate 101 is installed below the airframe 1. Two groups of second support plates 102 are symmetrically installed below the first support plate 101. A bomb - dropping box 2 is rotatably connected between the two groups of second support plates 102. A bomb - dropping port 201 is opened inside the bomb - dropping box 2. This fire - fighting unmanned aerial vehicle also has a rotating component at the second support plate for driving the bomb - dropping box to turn up and down. An ejection port is opened on one side wall of the bomb - dropping box. An ejection component for ejecting fire - fighting bombs in the direction of the ejection port is arranged inside the bomb - dropping box. By driving the bomb - dropping box to rotate through the rotating component, the fire - fighting bombs can fly obliquely upward or downward, thereby improving the applicability of the fire - fighting unmanned aerial vehicle. Through the guiding action of the first guiding plate and the second guiding plate on the fire - fighting bombs, it is ensured that the multiple fire - fighting bombs are not prone to chaos during the movement process. Through the setting of the second closing door, it is ensured that the fire - fighting bombs are not easily removed from the bomb - dropping box when there is no need to launch the fire - fighting bombs.

[0036] This application combines the above - mentioned prior art, as Figures 1-7As shown in the figure, the present invention provides a technical solution: a fire-fighting unmanned aerial vehicle capable of switching fire-extinguishing media. A material distribution component 3 is arranged inside the bomb dropping box 2. An annular groove 4 is formed on the top surface of the bomb dropping box 2. A fixing block 5 is installed on the top surface of the bomb dropping box 2. A positioning component 6 is arranged inside the fixing block 5;

[0037] The material distribution component 3 includes a storage tank 301 which is rotatably connected inside the bomb dropping box 2. A partition plate 302 is installed inside the storage tank 301. Two discharge ports 303 are installed on the bottom surface of the storage tank 301. A connecting rod 304 is installed on the top of the storage tank 301. A scraping plate 305 is installed on the bottom of the storage tank 301;

[0038] The positioning component 6 includes a plug rod 601 and a limiting groove 602. The plug rod 601 is inserted into the fixing block 5. The limiting groove 602 runs through the surface of the fixing block 5. A spring 603 is sleeved on the surface of the plug rod 601. A pulling plate 604 is installed at the top of the plug rod 601. A limiting block 605 is installed at the bottom of the plug rod 601.

[0039] In this implementation scheme: The material distribution component 3 is provided. Through the partition plate 302, the internal space of the storage tank 301 is divided into independent areas, which can accommodate two fire-extinguishing media at the same time, facilitating adaptation to different fire types. There is no need for the unmanned aerial vehicle to return to base to replace the fire-extinguishing media, which can improve the rescue efficiency to a certain extent. By rotating the storage tank 301, different discharge ports 303 can be switched to align with the bomb dropping port 201, realizing the rapid switching of fire-extinguishing media, which can improve the applicability and operation efficiency of the fire-fighting unmanned aerial vehicle. The scraping plate 305 is also provided. When the fire-extinguishing media in the storage tank 301 is switched, the bottom of the storage tank 301 is cleared to avoid the mixing of fire-extinguishing media or blockage, which may affect the dropping accuracy. The positioning component 6 is provided. Through the mechanical locking of the spring 603, the fixing block 5 and the limiting block 605, the storage tank 301 can be fixed at the selected position, avoiding mis-switching caused by vibration of the airframe 1 during flight and improving the operation accuracy. At the same time, by simply pulling the pulling plate 604, the limit of the storage tank 301 can be released, facilitating the rotation of the storage tank 301.

[0040] Combined with the above scheme:

[0041] Furthermore:

[0042] As Figures 2 to 4 shown;

[0043] In an alternative embodiment, in order to store the arc extinguishing medium in separate chambers, the storage tank 301 is evenly divided into two chambers by the partition plate 302, and the two discharge ports 303 are symmetrically arranged on the bottom surface of the storage tank 301 on both sides of the partition plate 302.

[0044] In this embodiment, the storage tank 301 is evenly divided into two chambers by a partition plate 302, which facilitates the storage tank 301 to store two fire extinguishing media simultaneously, so as to adapt to different types of fires and improve the rescue efficiency.

[0045] Combined with the above solution:

[0046] Furthermore:

[0047] As Figures 2 to 5 shown;

[0048] In an alternative embodiment, in order to facilitate the dispensing of the fire extinguishing medium, the shapes and sizes of the two sets of discharge ports 303 match the shapes and sizes of the bomb dropping ports 201.

[0049] In this embodiment, the shapes and sizes of the two sets of discharge ports 303 match the shapes and sizes of the bomb dropping ports 201. When the storage tank 301 is rotated, the discharge ports 303 and the bomb dropping ports 201 can be completely aligned, facilitating the dispensing of the fire extinguishing medium.

[0050] Combined with the above solution:

[0051] Furthermore:

[0052] As Figures 2 to 5 shown;

[0053] In an alternative embodiment, in order to facilitate the rotation of the storage tank 301, the connecting rod 304 is slidably connected to the inside of the annular groove 4, and the storage tank 301 is rotatably connected to the inside of the bomb dropping box 2 through the connecting rod 304.

[0054] In this embodiment, the connecting rod 304 is slidably connected to the inside of the annular groove 4. When the storage tank 301 is rotated, the storage tank 301 can drive the connecting rod 304 to slide in the annular groove 4. Since the shape of the annular groove 4 is annular, the storage tank 301 can be rotated, so as to rotate the storage tank 301.

[0055] Combined with the above solution:

[0056] Furthermore:

[0057] As Figures 2 to 4 shown;

[0058] In an alternative embodiment, in order to facilitate the rotation of the storage tank 301, a plurality of groups of grooves 306 are formed on the outer surface of the top end of the storage tank 301, and the plurality of groups of grooves 306 are arranged in a circumferential array on the top end of the storage tank 301.

[0059] In this embodiment: A number of groups of grooves 306 are formed on the outer surface of the top end of the storage tank 301, and the number of groups of grooves 306 are arranged in a circumferential array on the top end of the storage tank 301. When the storage tank 301 is rotated, the hand contacts the grooves 306 at the top end of the storage tank 301, which can increase the friction between the hand and the storage tank 301, thereby facilitating the rotation of the storage tank 301.

[0060] Combined with the above solution:

[0061] Furthermore:

[0062] As Figure 2 、 Figure 5 and Figure 6 shown;

[0063] In order to fix the storage tank 301, in an alternative embodiment, one end of the spring 603 is fixedly connected to the top surface of the limiting block 605, and the other end of the spring 603 is fixedly connected to the inner wall of the fixing block 5.

[0064] In this embodiment: One end of the spring 603 is connected to the top surface of the limiting block 605, and the other end of the spring 603 is connected to the inner wall of the fixing block 5. When the pull plate 604 is pulled, the pull plate 604 drives the limiting block 605 to move, and the limiting block 605 squeezes the spring 603 at this time. When the pull plate 604 is released, under the action of the self-elastic force of the spring 603, the limiting block 605 can be driven to move downward, thereby driving the insertion rod 601 to fix the storage tank 301.

[0065] Combined with the above solution:

[0066] Furthermore:

[0067] As Figures 5 to 6 shown;

[0068] In order to prevent the storage tank 301 from shaking, in an alternative embodiment, the shapes of the limiting block 605 and the limiting groove 602 are both cross-shaped.

[0069] In this embodiment: The shapes of the limiting block 605 and the limiting groove 602 are both set to be cross-shaped, which facilitates the sliding of the limiting block 605 through the limiting groove 602 in the fixing block 5. At the same time, the limiting block 605 can limit the insertion rod 601 to prevent the insertion rod 601 from rotating when the pull plate 604 is pulled, which affects the fixing effect of the storage tank 301.

[0070] Combined with the above solution:

[0071] Furthermore:

[0072] As Figures 1 to 2 shown;

[0073] In order to facilitate the rotation of the storage tank 301, in an alternative embodiment, the storage tank 301 is fixed by a positioning assembly 6.

[0074] In this embodiment: By fixing the storage tank 301 with the positioning assembly 6, it is convenient to fix the storage tank 301. Just by pulling the plate 604, the limit on the storage tank 301 can be released, thus facilitating the rotation of the storage tank 301.

[0075] Combined with the above solution:

[0076] Furthermore:

[0077] As Figure 1 、 Figure 2 and Figure 7 shown;

[0078] In order to observe the remaining capacity in the storage tank 301, in an alternative embodiment, two groups of indicating assemblies 7 are symmetrically arranged on the top surface of the storage tank 301. The indicating assembly 7 includes a long rod 701 which is slidably connected to the inside of the storage tank 301. A stopper 702 is installed at the top end of the long rod 701, and a floating ball 703 is installed at the bottom end of the long rod 701.

[0079] In this embodiment: The indicating assembly 7 is provided. Through the floating ball 703 and the long rod 701, the remaining stock of the fire extinguishing medium in the storage tank 301 can be monitored in real time, which is convenient for timely replenishment of the fire extinguishing medium, reducing ineffective delivery, and avoiding affecting the fire extinguishing effect.

[0080] Combined with the above solution:

[0081] Furthermore:

[0082] As Figure 7 shown;

[0083] In order to facilitate the quick inspection of the stock of the fire extinguishing medium, in an alternative embodiment, a scale groove 704 is formed on the surface of the long rod 701.

[0084] In this embodiment: By forming the scale groove 704 on the surface of the long rod 701, it is convenient to quickly inspect the stock of the two fire extinguishing media in the storage tank 301.

[0085] Working principle: When switching the fire extinguishing medium, pull the pull plate 604. The pull plate 604 drives the insertion rod 601 to move. The insertion rod 601 drives the limit block 605 to slide upward in the limit groove 602. At the same time, the limit block 605 squeezes the spring 603 until the insertion rod 601 is taken out of the storage tank 301. Rotate the storage tank 301. The storage tank 301 drives the connecting rod 304 to slide in the annular groove 4. At this time, the storage tank 301 can rotate in the bomb dropping box 2. When the storage tank 301 rotates, it drives the scraper 305 at its bottom to scrape the inside of the bomb dropping box 2, and at the same time drives the discharge port 303 to move until the bomb dropping port 201 and another group of discharge ports 303 are opposite. At this time, the fire extinguishing medium can be switched to adapt to different types of fires. When the fire extinguishing medium is consumed, the floating ball 703 drives the long rod 701 to slide on the top of the storage tank 301. By observing the scale groove 704, the remaining stock of the fire extinguishing medium in the storage tank 301 can be monitored in real time, so as to replenish the fire extinguishing medium in time and avoid affecting the rescue efficiency.

[0086] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
