Description

Technical Field

[0001] This utility model relates to the field of fire-fighting drone technology, specifically a rapid water intake device for high-altitude fire-fighting drones. Background Technology

[0002] During firefighting operations, a device is installed at the bottom of the drone to collect water. The ease of use of the water collection device can greatly improve the firefighting effect, and the rapid water collection device for drones can greatly reduce the risk of human rescue and improve the efficiency of firefighting. However, the existing rapid water collection devices for firefighting drones still have some defects in use. When the existing device collects water, a large amount of air is trapped inside the water tank, and it relies on its own gravity to collect water, which makes the water filling process very slow and cannot achieve rapid water filling. Patent publication number CN119607459A discloses a rapid water-collecting device for a drone used in fire rescue. A lifting screw controls the lifting ring, allowing for angle adjustment of nine drainage blocks. This adjusts the angle of the water discharged from the top during firefighting, and the area to be extinguished can be adjusted according to the size of the fire. During water collection, two drive pumps operate, rapidly extracting air from the water storage chamber through exhaust vents, accelerating the water collection process. After water collection, the drone rises, the sealing plate descends and closes with the sealing plate groove to prevent water leakage. The top drive motor drives two driven bevel gears to rotate via drive bevel gears, and two traction rope rollers rotate to release the traction ropes. Two water tanks descend to the water surface. Upon contact with the water surface, the float at the bottom lifts the internal sealing plate, allowing water to enter the water storage chamber. Two spray tanks are designed to open during water collection for easy access and close after collection, effectively protecting the internal water tanks. The bottom spray components also improve firefighting efficiency. In the aforementioned patent, the rapid water-collecting device for fire-fighting drones solves the problems mentioned above. However, the rapid water-collecting device for drones in this patent also has the following problems: during the water-collecting process, the float needs to push the sealing plate upward to separate from the bottom water-inlet ring and create a gap so that the water can enter the interior of the water tank. However, the water-collecting speed of the rapid water-collecting device is affected by the weight of the water tank body and also by the gap between the bottom water-inlet ring and the sealing plate, resulting in a slow water-collecting speed, which can easily affect the fire-fighting effect of the water-collecting device.

[0003] To address the aforementioned issues, an innovative design is urgently needed based on the existing water intake device structure. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid water intake device for high-altitude fire-fighting drones, in order to solve the problem that the water intake speed of the drone rapid water intake device mentioned in the background art is affected by the weight of the water tank body and also by the gap between the water intake bottom ring and the sealing plate, resulting in the water intake speed of the water intake device being too slow, which easily affects the water intake fire-fighting effect of the water intake device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid water intake device for a high-altitude firefighting drone, comprising a mounting plate and a sliding plate that slides on the upper end of the mounting plate; A traction rope is fixedly installed on the outer side of the sliding plate. An upper connecting ring is installed on the mounting plate through a fixed rod fixedly installed at its lower end. A connecting rope is fixedly installed at the lower end of the upper connecting ring, and a lower connecting ring is fixedly installed at the lower end of the connecting rope. The lower end of the lower connecting ring is fixedly installed with an upper fixing ring by a load-bearing rope. The lower end of the upper fixing ring is fixedly installed with a waterproof cylinder, and the lower end of the waterproof cylinder is fixedly installed with a lower fixing ring.

[0006] Preferably, the waterproof tube is made of flexible waterproof fabric, and the opening of the lower fixing ring at the lower end of the waterproof tube is smaller than the opening of the upper fixing ring, and the upper fixing ring, the upper connecting ring and the lower connecting ring are located outside the traction rope.

[0007] Preferably, a circular sealing plate is rotatably mounted on the upper end of the lower fixing ring and sealed therewith, and a lower magnetic ring is nested on the upper end of the lower fixing ring.

[0008] Preferably, an upper magnetic ring that attracts the lower magnetic ring is fixedly installed at the lower end of the circular sealing plate, and the upper end of the circular sealing plate is fixedly connected to the end of the traction rope away from the sliding plate.

[0009] Preferably, an electric push rod connected to the sliding plate is fixedly installed on the upper end of the mounting plate, and the two sets of electric push rods are located on both sides of the traction rope at the upper end of the mounting plate.

[0010] Preferably, two sets of fixing plates are fixedly installed on the upper end of the mounting plate, and the two sets of fixing plates are respectively located on both sides of the sliding plate, and a guide rod that is slidably connected to the sliding plate is fixedly installed between the two sets of fixing plates.

[0011] Preferably, a square tube is fixedly installed at the lower end of the mounting plate, and a square rod is slidably installed inside the square tube. A hook is fixedly installed at the end of the square rod away from the square tube, and a return spring is sleeved on the outer side of the end of the square rod close to the square tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By utilizing the elastic compression of the return spring to press the square rod, the square rod can slide inside the square tube, thereby allowing the hook to be stably fastened to the outside of the horizontal support rod at the lower end of the drone, ensuring the shock absorption effect of the water collection device during installation and use, and thus ensuring the stability of the water collection device during installation and use. 2. By using a drone to slide the waterproof cylinder inside the water surface, water can quickly enter the interior of the waterproof cylinder through the upper fixed ring, thereby shortening the time required for the device to collect water. Furthermore, during firefighting and rescue operations, the lower magnetic ring can be separated from the upper magnetic ring by opening the circular sealing plate, and the process of water being sprayed out of the device can be completed quickly, thereby improving the water collection and firefighting effect of the device. 3. Furthermore, by controlling the distance the sliding plate moves the traction rope, the size of the opening between the circular sealing plate and the lower fixed ring can be controlled, thereby controlling the water output of the device. This allows the device to provide limited fire extinguishing for fires of different sizes, ensuring its practicality. Attached Figure Description

[0015] 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.

[0016] In a specific embodiment, such as Figures 1-4 The process of installing the water intake device on the horizontal support rod at the lower end of the drone is shown in the figure. Mounting plate 1 and sliding plate 2 that slides on the upper end of mounting plate 1; a traction rope 3 is fixedly installed on the outer side of sliding plate 2; an upper connecting ring 5 is installed on mounting plate 1 through a fixed rod 4 fixedly installed at its lower end, and a connecting rope 6 is fixedly installed at the lower end of the upper connecting ring 5, and a lower connecting ring 7 is fixedly installed at the lower end of the connecting rope 6; two sets of fixed plates 16 are fixedly installed on the upper end of mounting plate 1, and the two sets of fixed plates 16 are respectively located on both sides of sliding plate 2, and a guide rod 17 that slides and connects with sliding plate 2 is fixedly installed between the two sets of fixed plates 16; a square cylinder 18 is fixedly installed on the lower end of mounting plate 1, and a square rod 19 is slidably installed inside the square cylinder 18, and a hook 20 is fixedly installed on the end of the square rod 19 away from the square cylinder 18, while a return spring 21 is sleeved on the outer side of the end of the square rod 19 close to the square cylinder 18. When using the rapid water collection device for high-altitude firefighting drones, the hook 20 needs to be hung on the outside of the two sets of horizontal support rods at the bottom of the drone first. Then, water can be collected for firefighting through the device. During the installation of the water collection device, the square rod 19 needs to be stretched and slid inside the square cylinder 18. As the square rod 19 slides, it will drive the hook 20 to move. At the same time, the return spring 21 will be compressed by the square rod 19 and the hook 20 and will engage with the horizontal support rod at the bottom of the drone. At this time, the return spring 21 is in a contracted state, so that the water collection device can be stably installed at the bottom of the drone. The amount of contraction of the return spring 21 can control the movement distance of the hook 20, so that the water collection device can be installed and used on the horizontal support rods of drones of different sizes, effectively improving the convenience of using the water collection device.

[0017] In one specific embodiment, such as Figures 1-6 The process by which the water-collecting device can quickly collect water is shown in the diagram. The lower end of the lower connecting ring 7 is fixedly installed with an upper fixing ring 9 via a load-bearing rope 8. The lower end of the upper fixing ring 9 is fixedly installed with a waterproof cylinder 10, and the lower end of the waterproof cylinder 10 is fixedly installed with a lower fixing ring 11. The waterproof cylinder 10 is made of flexible waterproof fabric, and the opening of the lower fixing ring 11 at the lower end of the waterproof cylinder 10 is smaller than the opening of the upper fixing ring 9. The upper fixing ring 9, the upper connecting ring 5, and the lower connecting ring 7 are located outside the traction rope 3. The upper end of the lower fixing ring 11 is rotatably installed with a circular sealing plate 12 that is sealed to it, and the upper end of the lower fixing ring 11 is nested with a lower magnetic ring 13. The lower end of the circular sealing plate 12 is fixedly installed with an upper magnetic ring 14 that attracts the lower magnetic ring 13, and the upper end of the circular sealing plate 12 is fixedly connected to the end of the traction rope 3 away from the sliding plate 2. The upper end of the mounting plate 1 is fixedly installed with an electric push rod 15 that is connected to the sliding plate 2, and the two sets of electric push rods 15 are located on both sides of the traction rope 3 at the upper end of the mounting plate 1.

[0018] When using the high-altitude firefighting drone's rapid water-collecting device, the drone can directly slide the water-collecting device on the upper part of the water surface. During this process, the waterproof cylinder 10 will move on the water surface, and the water will enter the interior of the waterproof cylinder 10 through the upper fixing ring 9. The connecting rope 6 will bend, causing the waterproof cylinder 10 to tilt inside the water flow. By controlling the height of the drone on the upper part of the water surface, the waterproof cylinder 10 can slide to the lower part of the water surface, allowing the interior of the waterproof cylinder 10 to quickly fill with water. During this process, the circular sealing plate 12 will be sealed with the lower fixing ring 11. After the interior of the waterproof cylinder 10 is filled with water, the drone will quickly take off, causing the waterproof cylinder 10 to separate from the water surface and transport the water inside to the fire site for firefighting. After the water intake device moves to the upper part of the fire, it can spray the water inside the waterproof cylinder 10. During this process, the electric push rod 15 needs to move and push the sliding plate 2. The electric push rod 15 is powered by the drone. The sliding plate 2 slides on the outside of the guide rod 17 and drives the traction rope 3 to move. The traction rope 3 moves inside the upper connecting ring 5 and the lower connecting ring 7 and pulls the circular sealing plate 12 to rotate. The circular sealing plate 12 rotates at the upper end of the lower fixing ring 11, creating a gap between the lower fixing ring 11 and the circular sealing plate 12. At this time, the water inside the waterproof cylinder 10 will be discharged through the gap between the lower fixing ring 11 and the circular sealing plate 12, so that the water can extinguish the fire. By controlling the distance that the sliding plate 2 drives the traction rope 3 to move, the rotation angle of the circular sealing plate 12 can be controlled, thereby controlling the water discharge speed of the waterproof cylinder 10, thus improving the fire extinguishing effect of the water intake device and increasing its overall practicality.
