Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically to a direct-spray water gun suitable for drones. Background Technology

[0002] With the widespread application of drone technology in firefighting, drones equipped with water spray equipment have become important tools for dealing with fires in high-rise buildings and complex terrain. However, similar direct-spray water guns on the market have many limitations: First, they lack dedicated quick-locking and unlocking mechanisms, making it impossible for drones to quickly detach from fire hoses in case of emergencies during high-altitude operations, posing a safety hazard; second, some key load-bearing components are assembled from multiple parts, resulting in insufficient structural strength, poor reliability, and cumbersome assembly; third, the anti-drop mechanism for the retractable nozzle often uses elastic clips and slots, requiring high installation precision, having low production error tolerance, and experiencing mechanical wear, leading to short service life and inconvenient disassembly and assembly. These problems seriously affect the safety, efficiency, and durability of firefighting operations, necessitating a structurally optimized direct-spray water gun adapted to the firefighting needs of drones. Utility Model Content

[0003] The purpose of this invention is to provide a direct-spray water gun suitable for drones.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A direct-spray water gun suitable for drones includes a first component, a second component, a quick-lock and first-unlock mechanism, a quick-lock and second-unlock mechanism, a magnetic anti-drop mechanism, a drone connection structure, and a nozzle assembly. The first component is formed by gluing a second pipe connector, a second carbon fiber tube, and a third pipe connector together. The first component also includes an internal hexagon countersunk head, which is fixed to one end of the third pipe connector by a square steel plate. The second component is formed by gluing a neodymium magnet, a first pipe connector, a first carbon fiber tube, and a straight connector together. The quick-lock and first-unlock mechanism consists of an electric push rod, a quick-release female head, a quick-lock pressure plate, and a quick-release male head. The quick-lock and second-unlock mechanism consists of a pipe hanging plate, a telescopic positioning pin, and a hanging bracket tray.

[0005] Preferably, in the quick-release locking and first unlocking mechanism, the quick-release female head is a quick-release connector containing a sealing ring and a spring piece, and the fire hose is connected to the water supply through the quick-release female head; when the quick-release pressure plate is reset upward, it pushes the quick-release female head to quickly lock and lock; the electric push rod is an electric push rod, which pushes the quick-release pressure plate downward after receiving the unlocking signal to unlock and separate the quick-release female head.

[0006] Preferably, in the quick-lock and second unlocking mechanism, the telescopic positioning pin is an elastic telescopic pin shaft, which is fixed to the hanging tray by a threaded connection; the hanging tray is an integrally machined structure, which is used to improve the overall structural strength.

[0007] Preferably, the magnetic anti-drop mechanism is adapted to the telescopic retraction of the first component. The first component and the nozzle are fixed by a threaded connection. The second pipe joint contacts the rubber ring to achieve the anti-leakage function. The second pipe joint cooperates with the first pipe joint to play a limiting role, preventing the first component from falling to the left when the water gun is working. The nozzle cooperates with the first pipe joint to achieve the limiting positioning of the first component after it is retracted.

[0008] Preferably, both the first carbon tube and the second carbon tube are made of carbon fiber tubes, and the first bracket tube and the second bracket tube are fixedly connected to the UAV through positioning holes and screw mounting holes.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] This utility model provides a direct-spray water gun suitable for drones. The first component is formed by gluing together a second pipe connector 23, a second carbon tube 26, and a third pipe connector 29. A square steel plate 30 is fixed to the countersunk head 31 with screws. The second component is formed by gluing together a neodymium magnet 1, a first pipe connector 2, a first carbon tube 3, and a straight connector 21. These two components are the core functional integrated parts of the water gun. The first component is fixed to the nozzle 28 by a threaded connection. During operation, the first component can withstand water pressure and move to the left. The second pipe connector 23 is in close contact with the rubber ring 27 to ensure no water leakage during water delivery. The third pipe connector 29 and the first pipe connector 2 form a double limit to prevent the first component from falling off to the left under water pressure. The nozzle 28 cooperates with the first pipe connector 2 to ensure that the first component is accurately positioned to the designated position when retracted.

[0019] The quick-release locking and first unlocking mechanism are key structures for connecting fire hoses. The quick-release female connector 15, as a quick-release joint, contains a sealing ring and a spring to achieve a sealed connection with the fire hose and a stable water supply. When the quick-release plate 16 is reset upwards, it can be manually pushed upwards to lock, ensuring the reliability of the connection. When the drone is in a sudden emergency, the electric push rod receives the unlocking signal and pushes the quick-release plate 16 downwards to release the locking state of the quick-release female connector 15, which can quickly separate the fire hose and prevent the hose from dragging and affecting the drone's emergency response.

[0020] In the quick-locking and second unlocking mechanism, the telescopic positioning pin 5 and the hanging tray 12 are fixed by threads to form a stable locking structure. The hanging tray 12 is integrally processed and formed. Compared with the traditional multi-part splicing design, it not only simplifies the assembly process, but also significantly improves the structural strength and load-bearing capacity, making it suitable for complex working conditions at height.

[0021] The second carbon tube 26 and the first carbon tube 3 are made of carbon fiber, minimizing the overall weight of the equipment while ensuring structural strength, thus avoiding increased flight load on the drone. The first and second bracket fittings are fixed to the drone fuselage through positioning holes and screw mounting holes, ensuring a secure connection and easy assembly and disassembly, allowing for quick assembly of the water gun and drone. The nozzle 28 is a replaceable nozzle, allowing users to replace it with different sizes according to the size of the fire and the required fire suppression range, improving the equipment's adaptability.

[0022] The components of this invention work together to ensure the safety and stability of high-altitude firefighting operations, simplify the installation and maintenance process, extend the service life of the equipment, and fully meet the actual needs of drone firefighting operations.

[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
