Description

Technical Field

[0001] This utility model relates to the field of continuous water supply technology for drones, and in particular to a continuous water supply device for fire-fighting drones. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. In practical applications, UAVs are often used for firefighting operations, which can extinguish fires from different angles and heights, and significantly improve the safety factor compared to human firefighting. When using UAVs for firefighting, they usually need to carry water tanks. The water stored in the tanks can provide a continuous water supply to the UAVs. When the UAVs land, the water tanks are the first thing to come into contact with the ground. However, due to the stability of the UAVs during flight, external wind direction, and the flatness of the ground, the water tanks may wobble and tip over upon landing, causing the UAVs to fall down through the rigging ropes. Therefore, it is necessary to maintain the stability of the water tanks upon landing.

[0003] Common continuous water supply devices for firefighting drones only include the function of continuous water supply, which can continuously supply water to the drone, but lack the function of stable landing. They cannot guarantee the stability of the water tank when landing. Due to the influence of external factors such as the stability of the drone's flight, external wind direction, and ground flatness, the water tank may shake and tip over when landing, thus pulling the drone down through the suspension rope, affecting the stability of the landing.

[0004] Therefore, to address the lack of a stable landing function in the aforementioned continuous water supply device for firefighting drones, a new continuous water supply device for firefighting drones can be designed. This device sends a start command to the PLC controller via the drone's remote control module. When the drone is descending and about to land, the PLC controller activates the air pump. The air pump delivers air into the annular airbag through a special-shaped air delivery pipe, causing the annular airbag to inflate. When the protective shell containing the water storage tank lands, the annular airbag is the first to contact the ground. The inflated annular airbag reduces the impact force on the protective shell upon landing. Once the protective shell has stabilized, the PLC controller opens the solenoid valve exhaust pipe, allowing the weight of the protective shell to compress the annular airbag. The air inside the annular airbag is then expelled through the solenoid valve exhaust pipe, ensuring the protective shell lands stably on the ground, thus achieving a stable landing. Utility Model Content

[0005] To overcome the common problem that fire-fighting drones' continuous water supply devices lack a stable landing function and cannot guarantee the stability of the water tank upon landing, the water tank is prone to shaking and tipping upon landing due to external factors such as the drone's flight stability, external wind direction, and ground flatness. This causes the drone to fall through the suspension rope, affecting the stability of the landing.

[0006] The technical solution of this utility model is as follows: a continuous water supply device for fire-fighting drones, including a protective shell; it also includes a supporting top plate, an annular airbag, an air pump, a special-shaped air delivery pipe and a solenoid valve exhaust pipe. The top of the protective shell is provided with a supporting top plate, and the bottom of the protective shell is provided with an annular airbag. The air pump is provided in the middle of the left side of the top of the supporting top plate. The output end of the air pump is connected to the special-shaped air delivery pipe. The end of the special-shaped air delivery pipe away from the air pump is connected to the front side of the annular airbag. The right end of the front side of the annular airbag is provided with a solenoid valve exhaust pipe.

[0007] Preferably, the drone's remote control module sends a start command to the PLC controller. When the drone is about to land, the PLC controller activates the air pump. The air pump delivers air into the annular airbag through a special-shaped air delivery pipe, causing the annular airbag to inflate. When the protective shell containing the water storage tank lands, the annular airbag is the first to contact the ground. The inflated annular airbag cushions the impact of the landing. Once the protective shell has stabilized, the PLC controller opens the solenoid valve exhaust pipe, allowing the weight of the protective shell to apply pressure to the annular airbag. When compressed, the air inside the annular airbag is discharged from the solenoid valve exhaust pipe, allowing the protective shell to be placed stably on the ground, achieving a stable landing function. This solves the problem of common fire-fighting drone continuous water supply devices, which only include continuous water supply function, can continuously supply water to the drone, but lack stable landing function, cannot guarantee the stability of the water tank when landing, and are prone to shaking and tipping when landing due to the influence of external factors such as the stability of the drone's flight, external wind direction, and ground flatness, thus pulling the drone down through the suspension rope and affecting the stability of the landing.

[0008] Preferably, a PLC controller is installed at the front end of the top right side of the support top plate, and a power supply battery is installed at the rear end of the top left side of the support top plate.

[0009] Preferably, a forklift fork is installed at the bottom of the protective shell, and a positioning frame is installed at the top of the forklift fork.

[0010] Preferably, the positioning frame is equipped with a water storage tank inside, with the bottom of the water storage tank placed on top of the forklift fork.

[0011] Preferably, a water supply interface is provided in the middle of the front side of the bottom of the water storage tank, and a water filling port is provided in the center of the top of the water storage tank.

[0012] As a preferred embodiment, four lifting rings are symmetrically arranged at the four corners of the top of the protective shell, and a diesel water pump is arranged at the top center of the supporting top plate.

[0013] Preferably, the input end on the right side of the diesel pump is connected to a special-shaped pumping pipe, and the end of the special-shaped pumping pipe away from the diesel pump is connected to the water supply interface.

[0014] The beneficial effects of this utility model are:

[0015] 1. The drone's remote control module sends a start command to the PLC controller. As the drone descends and approaches its final landing point, the PLC controller activates the air pump. The air pump delivers air through a special-shaped air delivery pipe into the annular airbag, causing it to inflate. When the protective outer shell containing the water storage tank lands, the annular airbag is the first to contact the ground. The inflated annular airbag cushions the impact of the landing. Once the protective shell has stabilized, the PLC controller opens the solenoid valve exhaust pipe, allowing the weight of the protective shell to further depress the annular airbag. When compressed, the air inside the annular airbag is discharged from the solenoid valve exhaust pipe, allowing the protective shell to be placed stably on the ground, achieving a stable landing function. This solves the problem of common fire-fighting drone continuous water supply devices, which only include continuous water supply function, can continuously supply water to the drone, but lack stable landing function, cannot guarantee the stability of the water tank when landing, and are prone to shaking and tipping when landing due to the influence of external factors such as the stability of the drone's flight, external wind direction, and ground flatness, thus pulling the drone down through the suspension rope and affecting the stability of the landing.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a continuous water supply device for a fire-fighting drone, including a protective shell 1; it also includes a supporting top plate 2, an annular airbag 3, an air pump 6, a special-shaped air delivery pipe 7, and a solenoid valve exhaust pipe 8. The supporting top plate 2 is located on the top of the protective shell 1, and the annular airbag 3 is located at the bottom of the protective shell 1. The air pump 6 is located in the middle of the left side of the top of the supporting top plate 2. The output end of the air pump 6 is connected to the special-shaped air delivery pipe 7. The end of the special-shaped air delivery pipe 7 away from the air pump 6 is connected to the front of the annular airbag 3. The solenoid valve exhaust pipe 8 is located at the right end of the front of the annular airbag 3. The drone's remote control module sends a start command to the PLC controller 4. When the drone is about to land, the PLC controller 4 controls the air pump 6 to start. The air pump 6 delivers air into the annular airbag 3 through the special-shaped air delivery pipe 7, thereby filling the annular airbag 3 with air and causing it to expand. When a water storage tank is installed... When the protective shell 1 of device 11 lands, the annular airbag 3 first contacts the ground. The inflated annular airbag 3 reduces the impact force when the protective shell 1 lands. After the protective shell 1 stabilizes, the PLC controller 4 controls the solenoid valve exhaust pipe 8 to open. The weight of the protective shell 1 then compresses the annular airbag 3, and the air inside the annular airbag 3 is discharged from the solenoid valve exhaust pipe 8, allowing the protective shell 1 to be placed stably on the ground. This achieves the function of a stable landing. This solves the problem of common fire-fighting drone continuous water supply devices, which only include the function of continuous water supply to the drone, but lack the function of stable landing. They cannot guarantee the stability of the water tank when landing. Due to the influence of external factors such as the stability of the drone's flight, external wind direction, and ground flatness, the water tank may shake and tip over when landing, causing the drone to fall through the suspension rope, thus affecting the stability of the landing.

[0023] Please see Figures 2-4In this embodiment, a water supply interface 12 is provided at the center of the front side of the bottom of the water storage tank 11, and a water inlet 16 is provided at the center of the top of the water storage tank 11. Four lifting rings 13 are symmetrically arranged at the four corners of the top of the protective shell 1. A diesel pump 14 is provided at the center of the top of the supporting top plate 2. A special-shaped water pump pipe 15 is connected to the input end on the right side of the diesel pump 14. The end of the special-shaped water pump pipe 15 away from the diesel pump 14 is connected to the water supply interface 12. Water is added into the interior of the water storage tank 11 through the water inlet 16. Then, the hoisting rope of the drone is connected to the four lifting rings 13. The drone nozzle is connected to the output of the diesel water pump 14. The drone is then taken off and lifted by the connection of the drone to the four lifting rings 13 via a sling. Once the drone reaches the designated location, it sends a fire extinguishing command to the drone's remote control module via a remote device. The drone's remote control module then controls the diesel water pump 14 to start. The diesel water pump 14 pumps water from the water storage tank 11 through the special-shaped water pipe 15 and delivers it to the drone's nozzle. Finally, the water is sprayed out through the drone's nozzle to extinguish the fire on site.

[0024] Please see Figures 1-4 In this embodiment, a PLC controller 4 is installed at the front end of the right side of the top of the supporting top plate 2, and a power supply battery 5 is installed at the rear end of the left side of the top of the supporting top plate 2. A forklift fork 9 is installed at the bottom inside the protective shell 1, and a positioning frame 10 is installed on top of the forklift fork 9. A water storage tank 11 is installed inside the positioning frame 10, and the bottom of the water storage tank 11 is placed on top of the forklift fork 9. After the fire extinguishing operation is completed, the drone is controlled to land via remote equipment. The drone's remote control module sends a start command to the PLC controller 4. When the drone is about to land, the PLC controller 4 controls the air pump 6 to start. The air pump 6 sends air into the annular airbag 3 through the special-shaped air delivery pipe 7, thereby making the inside of the annular airbag 3 filled with air. When the protective shell 1 containing the water storage tank 11 lands, it expands with air. The annular airbag 3 first contacts the ground, and the airbag 3 reduces the impact force when the protective shell 1 lands. After the protective shell 1 becomes stable, the PLC controller 4 controls the solenoid valve exhaust pipe 8 to open. The weight of the protective shell 1 then compresses the annular airbag 3, and the air inside the annular airbag 3 is discharged from the solenoid valve exhaust pipe 8, so that the protective shell 1 is placed stably on the ground. This achieves the function of a stable landing and prevents the water storage tank from shaking and tipping over when it lands due to external factors such as the stability of the drone's flight, external wind direction, and ground flatness. This would cause the drone to fall due to the suspension rope, affecting the stability of the landing.

[0025] During operation, water is added to the water storage tank 11 through the water inlet 16. The drone's sling is then connected to the four lifting rings 13, and the drone's nozzle connection pipe is connected to the output of the diesel pump 14. The drone then takes off, lifting the water storage tank 11 via the sling and lifting rings 13. Once the drone reaches the designated location, it sends a fire extinguishing command to the drone's remote control module via a remote device. The remote control module then starts the diesel pump 14, which pumps water from the water storage tank 11 through the special-shaped pumping pipe 15 and delivers it to the drone's nozzle. The water is then sprayed out through the drone's nozzle to extinguish the fire. After the fire extinguishing operation is completed, the drone is lowered back into position via the remote device. Upon landing, the drone's remote control module sends a start command to the PLC controller 4. As the drone descends and approaches its final destination, the PLC controller 4 activates the air pump 6. The air pump 6 delivers air into the annular airbag 3 through the shaped air delivery pipe 7, causing the annular airbag 3 to inflate. When the protective outer shell 1 containing the water storage tank 11 lands, the annular airbag 3 first contacts the ground. The inflated annular airbag 3 reduces the impact force of the protective outer shell 1 upon landing. Once the protective outer shell 1 stabilizes, the PLC controller 4 opens the solenoid valve exhaust pipe 8, allowing the weight of the protective outer shell 1 to compress the annular airbag 3. The air inside the annular airbag 3 is then expelled through the solenoid valve exhaust pipe 8, ensuring that the protective outer shell 1 is placed stably on the ground, thus achieving a stable landing.

[0026] Through the above steps, the remote control module of the drone sends a start command to the PLC controller 4. When the drone is about to land, the PLC controller 4 controls the air pump 6 to start. The air pump 6 sends air into the annular airbag 3 through the special-shaped air delivery pipe 7, causing the annular airbag 3 to be filled with air and inflated. When the protective shell 1 containing the water storage tank 11 lands, the annular airbag 3 is the first to contact the ground. The inflated annular airbag 3 reduces the impact force of the protective shell 1 upon landing. After the protective shell 1 stabilizes, the PLC controller 4 controls the solenoid valve exhaust pipe 8 to open, thereby allowing air to pass through the protective shell 1. The force of gravity compresses the annular airbag 3, and the air inside the annular airbag 3 is discharged from the solenoid valve exhaust pipe 8, so that the protective shell 1 is placed stably on the ground, realizing the function of stable landing. This solves the problem of common fire-fighting drone continuous water supply devices, which only have the function of continuous water supply, can continuously supply water to the drone, but lack the function of stable landing. They cannot guarantee the stability of the water tank when landing. Due to the influence of external factors such as the stability of the drone's flight, external wind direction and ground flatness, the water tank may shake and tip over when landing, thus pulling the drone down through the suspension rope, affecting the stability of the landing.
