Description

Technical Field

[0001] This invention relates to the field of drone mounting equipment technology, and in particular to a drone water gun with a self-detachable water hose. Background Technology

[0002] Drone water guns are specialized functional mounting devices in the field of drone equipment technology. They are core mounting components that enable liquid spraying operations based on the drone flight platform. They can be adapted and installed with various drones through a dedicated connection structure. Some models are also equipped with matching adjustment mechanisms such as angle adjustment, displacement control, and reaction force buffering. They can adjust water pressure and spray angle according to the drone's operational needs. Their overall design and adaptability are customized based on the drone's flight characteristics and payload capacity. They can be used with drones to complete operations in high-altitude and complex terrain scenarios. At present, they are mainly mounted on fire-fighting and cleaning drones in the form of high-pressure spray to achieve functions such as fire fighting and high-altitude curtain wall cleaning. They are important mounting equipment for expanding the operational capabilities of drones in various application fields. Their technological research and development and upgrades always keep in line with the adaptability and collaborative technical requirements of drone mounting equipment.

[0003] When drones are used for firefighting, their rotorcraft, which relies on propeller rotation to generate lift, is highly sensitive to airflow disturbances. Approaching a fire at close range, they face multiple unstable factors, including severe air turbulence, heat waves, and crosswinds. Furthermore, operating under load, they are highly susceptible to loss of control and even crashes. If the water or foam hoses cannot be disengaged in time, this instability will further exacerbate the drone's instability, potentially leading to wider personal injury and property damage. However, current technology lacks a reliable connection between the hose and the nozzle. The dynamic detachment mechanism is prone to response failure under special working conditions such as high temperature and vibration, which affects the reliable detachment of the hose. Although some solutions use multiple sets of safety redundancy servo motors to improve reliability, when one or more sets of servo motors fail, the thrust of the remaining servo motors often concentrates on one side of the hose joint, resulting in an uneven axial thrust on the hose. The joint is prone to tilting to the other side and deviating from the joint axis, thereby increasing the frictional resistance of the contact surface on the other side. This may still hinder the smooth detachment of the hose and reduce the safety and reliability of UAV firefighting operations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, the automatic hose detachment mechanism of the drone fire extinguishing is prone to response failure under harsh working conditions such as high temperature and vibration. Moreover, when multiple redundant servo motors fail, uneven thrust distribution will cause the joint to be skewed and the frictional resistance to increase, thereby affecting the reliable detachment of the hose and reducing the safety and stability of the drone fire extinguishing operation. Therefore, we propose a drone water gun with a self-detaching hose.

[0005] To achieve the above objectives, this application adopts the following technical solution: a drone water gun with a self-detachable hose, comprising: an outer interface, a water gun connector fixedly inserted on one side of the inner side of the outer interface, and a hose connector inserted on the other side of the inner side of the outer interface; a force-bearing component installed around the end of the hose connector; the force-bearing component includes three sets of force-bearing blocks arranged in a ring around the hose connector, and the force-bearing blocks are fixedly connected to the hose connector; a pulling component is installed inside the outer interface, and the pulling component is disposed between the hose connector and the water gun connector; the pulling component includes a pull ring sleeved inside the outer interface; a sealing ring is fixedly connected to the side of the pull ring; three sets of connecting blocks are arranged in a ring around the pull ring; a pulling block is fixedly connected to the end of each connecting block; and an inward pushing group is provided on the side of the pulling block away from the connecting block. The internal push assembly includes three sets of push blocks arranged in a ring array. A slider is fixedly connected to the outer wall of each push block, and a spring is fixedly connected to the side of each slider. An external push assembly is fitted around the sealing ring, including a spring, with three sets of push blocks arranged in a ring array at the end of the spring. When the hose connector is inserted into the external interface and secured, the force-bearing block aligns with the push block, and the spring provides a pushing force towards the hose connector through the push block. The pull block aligns with the push block, and the spring provides a pushing force towards the hose connector through the push block. When the hose connector needs to be detached from the external interface, the hose connector rotates to align the force-bearing block with the push block, and the spring provides a pushing force towards the hose connector through the push block, assisting the hose connector in detaching from the external interface.

[0006] Preferably, a force-bearing slider is fixedly connected to the outer wall of the force-bearing block, and a groove is provided inside the outer interface, with the force-bearing slider slidably connected inside the groove.

[0007] Preferably, the outer interface is further provided with an annular groove, and the sliding groove is connected to the annular groove. When the water hose connector rotates, the force-bearing slider slides along the annular groove.

[0008] Preferably, a connecting rubber ring is fixedly connected to the side of the pull ring away from the sealing ring, and the side of the connecting rubber ring away from the pull ring is fixedly connected to the end face of the water gun connector.

[0009] Preferably, the second slider is slidably connected to the inner wall of the outer interface, and the end of the second spring away from the second slider is fixedly connected to the outer interface.

[0010] Preferably, the end of the spring away from the push block is fixedly connected to the outer interface, and a slider is fixedly connected to the outer wall of the push block, and the slider is slidably connected to the inside of the outer interface.

[0011] Preferably, a sealing ring 2 is fixedly connected to one end face of the water hose connector inserted into the external interface portion, and a water supply hose is fixedly connected to the other end of the water hose connector.

[0012] Preferably, a water gun bend is fixedly connected to the end of the water gun connector away from the external interface, and a water gun extension tube is fixedly connected to the end of the water gun bend away from the water gun connector. An adjustable water gun nozzle is installed at the end of the water gun extension tube.

[0013] Preferably, the water hose connector is externally fixedly fitted with a support plate, and a clamping assembly is installed on the side of the support plate. The clamping assembly includes a clamping ring fixedly connected to the side of the support plate. The side of the clamping ring has an insertion slot in a circular array. A clamping block is engaged internally with the clamping ring, and the clamping block is fixedly connected to the end of the external interface.

[0014] Preferably, the outer wall of the external interface is provided with three sets of safety disengagement servos in a ring array. Each safety disengagement servo includes a servo controller, a swing push rod is installed on the side of the servo controller, a rotating mechanism is installed at the end of the servo controller, and an elastic telescopic link is fixedly connected to the bottom of the rotating mechanism. A toggle block is fixedly connected to the bottom end of the elastic telescopic link, and a toggle latch is engaged on the side of the toggle block. The end of the toggle latch is fixedly connected to the support plate. The outer cover of the safety disengagement servo is provided with a protective cover.

[0015] The technical effects and advantages of this invention are as follows: This invention significantly improves the reliability of hose detachment and the safety of drone operations under harsh conditions such as high temperature, strong vibration, and complex airflow by combining a three-set safety detachment servo motor in a ring array with an outward thrust component at the hose-gun joint of the drone. The three sets of safety detachment servo motors form a multi-redundant structure, so even if some safety detachment servo motors fail, the remaining safety detachment servo motors can still provide sufficient thrust. Combined with the axial auxiliary thrust uniformly applied to the end of the hose joint by the internal outward thrust component, it effectively fills the thrust loss on the fault side, reduces the risk of deflection and jamming of the hose joint due to unilateral force, and ensures that the hose can still detach smoothly under non-ideal conditions. At the same time, the combination of the external clamping component's clamping and locking with the opposing extrusion force of the outward and internal thrust components on the two sets of sealing strips enhances the sealing performance and connection stability of the joint, effectively compensates for processing errors and wear, reduces high-pressure water leakage, and improves the overall reliability and durability of drone firefighting operations.

Detailed Implementation

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figure 1 and Figure 3 As shown, the present invention provides a technical solution: a drone water gun with a self-detachable water hose, comprising: an external interface 3, a water gun connector 2 fixedly inserted on one side of the interior of the external interface 3, and a water hose connector 1 inserted on the other side of the interior of the external interface 3, a sealing ring 16 fixedly connected to one end of the water hose connector 1 inserted into the external interface 3, and a water supply hose 11 fixedly connected to the other end of the water hose connector 1, a water gun bend 12 fixedly connected to one end of the water gun connector 2 away from the external interface 3, and a water gun extension tube 13 fixedly connected to one end of the water gun bend 12 away from the water gun connector 2, and an adjustable water gun nozzle 14 installed at the end of the water gun extension tube 13; the water gun extension tube 13 is fixed on the drone, and the water supply hose 11 is used to provide a water source.

[0021] Please see Figure 11 As shown, a support plate 10 is fixedly sleeved on the outside of the hose connector 1. A clamping assembly 9 is installed on the side of the support plate 10. The clamping assembly 9 includes a clamping ring 901 fixedly connected to the side of the support plate 10. Insertion slots 902 are opened in an annular array on the side of the clamping ring 901. A clamping block 903 is engaged inside the clamping ring 901 and is fixedly connected to the end of the outer interface 3. The clamping block 903 is inserted into the insertion slot 902. After rotation, the clamping block 903 and the clamping ring 901 are aligned and clamped, thereby realizing the fixed connection between the hose connector 1 and the outer interface 3.

[0022] When drones perform firefighting missions, their flight attitude is extremely sensitive to surrounding airflow disturbances due to the high-speed rotation of their rotor blades, making them more susceptible to changes in external airflow compared to fixed-wing aircraft. Furthermore, during firefighting operations, drones need to approach the fire scene at close range. The intense thermal convection caused by the high temperature of the fire, updrafts, and air turbulence caused by complex building structures further destabilize the drone's flight environment. Simultaneously, when flying with loads such as water cannons and hoses, the drone's maneuverability and wind resistance are further reduced. If it encounters a sudden crosswind or heat wave, it is highly susceptible to loss of control, shaking, or even a crash. If, in this uncontrolled state, the water supply hose 11 connecting the drone to the ground water supply system fails to detach in time, it will create a continuous drag force, further exacerbating the drone's instability and potentially causing it to be pulled towards the ground or buildings, leading to secondary accidents and causing wider casualties and property damage. To address this technical problem and prevent damage to the drone caused by the failure of the water supply hose 11 to detach, this application makes the following improvements: Please refer to... Figure 2 and Figure 12As shown, the outer wall of the external interface 3 is equipped with three sets of safety detachment servos 4 in a ring array. Each safety detachment servo 4 includes a servo controller 401, a swing push rod 402 mounted on the side of the servo controller 401, a rotating mechanism 403 mounted at the end of the servo controller 401, and an elastic telescopic connecting rod 404 fixedly connected to the bottom of the rotating mechanism 403. A toggle block 405 is fixedly connected to the bottom end of the elastic telescopic connecting rod 404, and a toggle latch 406 is engaged on the side of the toggle block 405. The end of the toggle latch 406 is fixedly connected to the support plate 10. The safety detachment servo 4 is covered with a protective cover 15. When it is necessary to detach the water supply hose 11... When the device is released, the servo controller 401 receives a command and pushes the support plate 10 to rotate through the toggle block 405 and the toggle latch 406, so that the insertion latch 902 is aligned with the clamping block 903 again. Then, the swing push rod 402 rotates outward to provide a thrust to the support plate 10, causing the support plate 10, the hose connector 1, and the water supply hose 11 to detach. In the high temperature, strong vibration, and complex airflow environment of actual fire fighting operations, the servo may experience response delay or failure. The three sets of safety release servos 4 work independently to form a multi-redundant structure. Even if one or two sets fail, the remaining safety release servos 4 can still provide sufficient thrust to detach the water supply hose 11.

[0023] However, once one or more sets of safety release servos 4 in the ring array fail to function properly, the thrust provided by the remaining safety release servos 4 will no longer be evenly distributed circumferentially along the hose connector 1, but will be concentrated on one side of the hose connector 1. The hose connector 1 at the location where the safety release servo 4 fails on the other side will not receive thrust. This unilateral force can easily cause the hose connector 1 to shift laterally or tilt during the release process, causing its axis to no longer align with the release direction. This results in uneven distribution of contact pressure between the hose connector 1 and the external interface 3, increasing local frictional resistance, and even causing jamming, which may still hinder the timely release of the water supply hose 11. To solve this technical problem, this application makes the following improvements: Please refer to Figure 9 and Figure 10 As shown, a force-bearing component 5 is installed on the periphery of the end of the hose connector 1. The force-bearing component 5 includes three sets of force-bearing blocks 501 arranged in a ring around the periphery of the hose connector 1. The force-bearing blocks 501 are fixedly connected to the hose connector 1. A force-bearing slider 502 is fixedly connected to the outer wall of the force-bearing block 501. A groove 503 is opened inside the outer interface 3. The force-bearing slider 502 is slidably connected to the inside of the groove 503. An annular rotating groove 504 is also opened inside the outer interface 3. The groove 503 and the annular rotating groove 504 are connected. When the hose connector 1 rotates, the force-bearing slider 502 slides along the annular rotating groove 504. The ends of the force-bearing blocks 501 are all rounded.

[0024] Please see Figure 6As shown, a pulling component 7 is installed inside the external interface 3, and the pulling component 7 is located between the hose connector 1 and the water gun connector 2. The pulling component 7 includes a pull ring 703 sleeved inside the external interface 3. A sealing ring 704 is fixedly connected to the side of the pull ring 703. Three sets of connecting blocks 702 are arranged in a ring array around the pull ring 703. A pull block 701 is fixedly connected to the end of the connecting block 702. The end of the pull block 701 is also rounded, and the thickness of the pull block 701 is consistent with the thickness of the force-bearing block 501. A connecting rubber ring 705 is fixedly connected to the side of the pull ring 703 away from the sealing ring 704. The side of the connecting rubber ring 705 away from the pull ring 703 is fixedly connected to the end face of the water gun connector 2.

[0025] Please see Figure 8 As shown, an inner push component 8 is provided on the side of the pull block 701 away from the connecting block 702. The inner push component 8 includes three sets of push blocks 801 arranged in a circular array. The two ends of the push blocks 801 are provided with receiving inclined surfaces on the side near the pull component 7, and each corner is rounded. A slider 802 is fixedly connected to the outer wall of the push block 801, and a spring 803 is fixedly connected to the side of the slider 802. The slider 802 is slidably connected to the inner wall of the outer interface 3. The end of the spring 803 away from the slider 802 is fixedly connected to the outer interface 3, and the spring 803 is in a pre-compressed state.

[0026] Please see Figure 7 As shown, an external push assembly 6 is sleeved on the outside of the sealing ring 704. The external push assembly 6 includes a spring 601, and three sets of push blocks 602 are arranged in a ring array at the end of the spring 601. The end of the spring 601 away from the push block 602 is fixedly connected to the outer interface 3. A slider 603 is fixedly connected to the outer wall of the push block 602, and the slider 603 is slidably connected to the inside of the outer interface 3. During the process of inserting the hose connector 1 into the outer interface 3, the force-bearing block 501 is aligned with the push block 602. When the hose connector 1 is fully inserted and needs to be tightened, the hose connector 1 is rotated so that the force-bearing block 501 gradually rotates from being aligned with the push block 602 to being aligned with the push block 801.

[0027] Please see Figure 5As shown, when the hose connector 1 is inserted into the external interface 3 and locked in place, the force-bearing block 501 aligns with the push block 801, and the spring 803 provides a pushing force towards the hose connector 2 through the push block 801. The pull block 701 aligns with the push block 602, and the spring 601 provides a pushing force towards the hose connector 1 through the push block 602. The mechanical locking structure achieved externally by the locking assembly 9 ensures that the sealing ring 16 and the sealing ring 704 are tightly attached. Furthermore, the internal pushing assembly 8 and the pulling assembly 7 further... Sealing ring 16 and sealing ring 704 are subjected to opposing pushing forces, which apply continuous and relative compressive forces to both of them, ensuring that sealing ring 16 always remains in close contact with the end face of sealing ring 704. This effectively compensates for wear caused by processing errors, assembly gaps, or long-term use, enhances the sealing effect under the impact of high-pressure water flow, and reduces the risk of leakage. At the same time, the flexible support of the spring can buffer the vibration and pulling of the water supply hose 11 during the flight of the UAV, thereby improving the stability and durability of the connection between the hose connector 1 and the water gun connector 2 under complex working conditions.

[0028] Please see Figure 4 As shown, when the hose connector 1 needs to detach from the outer interface 3, the hose connector 1 rotates so that the force-bearing block 501 aligns with the push block 602. The spring 601 provides a pushing force towards the force-bearing block 501 through the push block 602, which is used to assist the hose connector 1 in detaching from the outer interface 3. The outward auxiliary thrust provided by the push assembly 6 and the force-bearing assembly 5 to the hose connector 1, together with the active thrust of the external safety disengagement servo 4, can significantly improve the reliability and response speed of the detachment of the hose connector 1 and the water supply hose 11. The thrust of the push assembly 6 can provide auxiliary power at the moment the safety disengagement servo 4 is activated, so that the hose connector 1 can quickly overcome frictional resistance and achieve separation. Especially when the thrust of the safety disengagement servo 4 is insufficient or partially malfunctioning, the elastic force provided by the push assembly 6 can still ensure that the hose connector 1 obtains sufficient initial separation force, effectively avoiding detachment failure due to insufficient thrust.

[0029] In the event of a partial servo motor malfunction leading to uneven thrust, the axial thrust provided by the external thrust assembly 6 can be evenly applied to the end of the hose connector 1 through the force-bearing assembly 5, effectively filling the thrust loss on the faulty side and significantly reducing the severe axial misalignment caused by the force-bearing assembly 5 being completely unforced on one side. This avoids the risk of a sharp increase in local friction and jamming due to excessive tilting between the hose connector 1 and the external interface 3, allowing the hose to detach smoothly even under non-ideal force conditions, thereby improving the fault tolerance and overall reliability of the hose detachment mechanism under fault conditions.

[0030] Working principle: Before the hose connector 1 is inserted into the outer interface 3, the pull block 701 is aligned with the push block 801. During insertion, the force-receiving slider 502 is aligned and slides into the groove 503. Then, the force-receiving locking block 501 contacts the push block 602 and continues to push, compressing the spring 601, causing the spring 601 to generate a spring restoring force towards the hose connector 1. When the force-receiving locking block 501 is aligned with the pull block 701, the force-receiving slider 502 is just aligned with the annular groove 504. At this time, the hose connector 1 is rotated, causing the force-receiving component 5 to rotate as well, so that the force-receiving locking block 501 rotates to align with the inner push component 8, and the spring 801... 803 provides a pushing force to the force-bearing block 501 towards the water gun connector 2 through slider 2 802 and push block 2 801, thereby driving the hose connector 1 and sealing ring 2 16 to move further towards the water gun connector 2. While rotating, the force-bearing block 501 pushes the pulling assembly 7 to rotate, causing the pulling block 701 to rotate to the position aligned with push block 1 602. At this time, the compressed spring 1 601 generates a pushing force towards the hose connector 1 through push block 1 602, which in turn, through connecting block 702 and pull ring 703, moves the sealing ring 1 704 towards the hose connector 1. The spring 2 803 and spring 1 601... Under the action of 1, the sealing ring 16 and the sealing ring 704 are subjected to opposing pushing forces, thereby further improving the stability of the contact between them; after the hose connector 1 is fully inserted into the outer interface 3, the clamping block 903 is also aligned with the insertion slot 902. When the hose connector 1 rotates, the clamping ring 901 rotates together with the support plate 10, so that the clamping block 903 and the insertion slot 902 are misaligned and locked together with the clamping ring 901 for fixation; when it is necessary to detach the hose, the servo controller 401 receives the command issued by the UAV, and the rotating mechanism 403 drives the elastic telescopic link 404 to rotate, its bottom The end pushes the latch 406 by the actuating block 405, which in turn pushes the support plate 10 and the water hose connector 1 to rotate together, so that the clamping block 903 is aligned with the insertion latch 902. At the same time as the water hose connector 1 rotates, it also drives the force-receiving component 5 to rotate. The force-receiving latch 501 rotates to align with the spring 601. At this time, the pushing force of the spring 601 and the push block 602 acts on the force-receiving component 5, which provides an outward pushing force to the water hose connector 1. At the same time, the swing push rod 402 rotates outward to push the support plate 10. The two interact to push the water hose connector 1 outward, so that the water hose connector 1 is detached from the water supply hose 11.

[0031] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
