Description

Technical Field

[0002] Forest fires often pose a serious threat to human life, property and ecological environment, and have gradually attracted public attention in recent years. However, due to the high requirements for firefighters, the rapid spread of fire, and the complex fire terrain, traditional fire fighting systems are difficult to meet the requirements of forest fire fighting. In addition, the outbreak of forest fires is often accompanied by suddenness and randomness. These factors make forest fire fighting difficult and pose a serious threat to the life safety of firefighters. The economic burden caused by wildfires is huge every year. Therefore, it is particularly important to find a more efficient fire extinguishing method to reduce the risk of forest fire fighting;

At the same time, amphibious aircraft have obvious advantages in forest fire fighting and fire rescue, including strong maneuverability, high fire fighting accuracy, and no restrictions on terrain and personnel.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 , the present invention provides a technical solution:

[0033] An aircraft water-drawing device comprises a main water pipe 3, the upper end of the main water pipe 3 is connected and fixed with two water branch pipes 2, and the two ends of the two water branch pipes 2 are respectively connected with water tanks 1 in a rotatable manner, a flow-dividing regulating mechanism 4 is arranged inside the main water pipe 3, and a storage regulating mechanism 8 is arranged at the upper end of the water branch pipe 2; the lower end of the main water pipe 3 is fixedly connected with a water suction pipe 5, and the lower end of the water suction pipe 5 is provided with a water suction port 7;

[0035] The diversion regulating mechanism 4 includes a sleeve 42 fixed to the outside of the main water pipe 3, a micro motor 41 is fixed to the outside of the sleeve 42, and a diversion plate 1 44 and a diversion plate 2 46 are arranged in the main water pipe 3, wherein the micro motor 41 is transmission-connected to the diversion plate 2 46;

[0036] The storage and adjustment mechanism 8 includes a fixed plate 83 fixed in the middle of the water distribution pipe 2, a servo motor 82 is fixed in the fixed plate 83, and connecting rods 81 are fixed to the output shafts at both ends of the servo motor 82. The end of the connecting rod 81 away from the servo motor 82 is transmission-connected to the water distribution pipe 2, and the water distribution pipe 2 is rotationally connected to the water tank 1.

[0037] By adopting the above technical scheme, the present invention can drive the adjustment angle of the main water pipe 3 and the water branch pipe 2 through the storage adjustment mechanism 8, so as to realize the angle adjustment and storage of the lower side water suction pipe 5, so that when the device is installed on the aircraft, the water suction angle of the water suction pipe 5 and the water suction port 7 can be changed according to the water suction terrain and the surrounding environment, thereby improving the application scope and use efficiency of the device; the water volume drawn from the water tanks 1 on both sides can be automatically adjusted through the diversion adjustment mechanism 4, so that the water volume of the water tanks 1 on both sides is consistent, and the device can automatically adjust the water suction flow rate of the water tanks 1 on both sides according to the water suction volume of the water tanks 1 on both sides, so that the water suction volume of the water tanks 1 on both sides is balanced and uniform.

[0038] As an embodiment of the present invention, Figure 5 As shown, a spiral diverter plate 31 is fixed inside the main water pipe 3 at the lower side of the diverter regulating mechanism 4, and the spiral diverter plate 31 is made of stainless steel metal material, and the spiral diverter plate 31 has a three-section structure design, and the angle between each section is 90°.

[0039] By adopting the above technical solution, the water sucked into the water suction pipe 5 can be spirally diverted to reduce the entry of air, with the aim of increasing the turbulence of the water flow basin and reducing the impact of the water flow.

[0040] As an embodiment of the present invention, Figure 5 and Figure 6 as well as Figure 7 As shown, the outer ring side of the diverter disc 1 44 in the diverter regulating mechanism 4 is fixed to the inner wall of the main water pipe 3, and the outer ring side of the diverter disc 2 46 is fixed with an annular slide rail, and the inner wall of the main water pipe 3 and the diverter disc 2 46 are provided with a slide groove at the corresponding position, and the diverter disc 2 46 is rotatably connected to the main water pipe 3 through the slide rail and the slide groove, and the adjacent surfaces of the diverter disc 1 44 and the diverter disc 2 46 are fitted, and the upper end surface of the diverter disc 1 44 is symmetrically provided with a diverter port 1 45, and the upper end of the diverter disc 2 46 is provided with a diverter port 1 A second diversion port 47 is symmetrically provided on the surface, and the diversion port 1 45 is staggered with the diversion port 2 47, and the diameters of the two are inconsistent. A gear 1 461 is fixedly connected to the middle of the lower end surface of the diversion plate 2 46, and a transmission rod 48 is meshingly connected to one side of the gear 1 461. A spiral blade 49 is fixed to the outside of the transmission rod 48, and the transmission rod 48 is meshed with the gear 1 461 through the spiral blade 49. The other end of the transmission rod 48 is fixed to the output shaft of the micromotor 41.

[0041] By adopting the above technical solution, the present invention sets water level sensors in the water tanks 1 on both sides, and then sets a control module and a battery assembly outside the water tanks 1. When the device draws water through the water suction pipe 5 and injects water into the water tanks 1 on both sides through the main water pipe 3, the diversion regulating mechanism 4 and the water diversion pipe 2, once there is an error in the water volume in the water tanks 1 on both sides, such as the water volume in the left water tank 1 is lower than that in the right water tank 1, the control module controls the micro motor 41 to rotate counterclockwise, thereby driving the transmission rod 48 and the spiral blade 49 to rotate. At this time, the transmission connection 49 meshes with the spiral blade 49 outside the transmission rod 48. The connected gear 1 461 rotates, and at this time, the diverter plate 2 46 rotates clockwise inside the main water pipe 3 through the slide rail and the slide groove, and then the left diverter port 1 45 and the diverter port 2 47 gradually overlap, and the aperture through which the water flows becomes larger, while the right diverter port 1 45 and the diverter port 2 47 gradually misalign, and the aperture through which the water flows becomes smaller. Therefore, the amount of water flowing through the water diverter pipes 2 on both sides is adjusted and changed, thereby supplementing the water inlet of the left water tank 1 and achieving balanced water inlet of the water tanks 1 on both sides. Conversely, the micromotor 41 is driven in the reverse direction to rotate, so as to supplement the right water tank 1 and adjust the water inlet flowing through the water diverter pipes 2 on both sides.

[0042] As an embodiment of the present invention, Figure 6 As shown, a diverter plate 43 is fixed on the upper end surface of a diverter disk 44 in the diverter regulating mechanism 4 inside the main water pipe 3, and the diverter plate 43 is designed in a wave-like structure.

[0043] By adopting the above technical solution, the diverter plate 43 with a wavy structure can evenly separate the water flowing through the diverter regulating mechanism 4, and the diverter plate 43 with a wavy structure can reduce the generation of bubbles in the flowing water and reduce the amount of excess air in the water tank 1 that touches the red line.

[0044] As an embodiment of the present invention, Figure 3 and Figure 4 As shown, the storage and adjustment mechanism 8 includes a fixed shell 86 rotatably connected to the interface of the water tank 1, and the outside of the fixed shell 86 is fixedly connected with a gear three 85. One end of the connecting rod 81 is rotatably connected to the water tank 1, and the connecting rod 81 is located on the upper side of the gear three 85. The outer surface of the connecting rod 81 is sleeved and fixed with a gear two 84 at a position corresponding to the gear three 85, and the gear three 85 is meshingly and transmission-connected with the gear two 84.

[0045] By adopting the above technical scheme, when the device is working, since the device is installed on the aircraft, the environment of the water source, the changes in water flow and terrain will affect the water drawing efficiency. Therefore, by controlling the rotation of the servo motor 82, the connecting rod 81 is driven to rotate. At this time, the gear two 84 connected to the connecting rod 81 is meshed with the gear three 85, thereby driving the gear three 85 to rotate. At this time, the fixed shell 86 rotates, driving the water distribution pipe 2 and the main water pipe 3 and the water suction pipe 5 fixed to the fixed shell 86 to rotate as a whole, thereby realizing the change of the angle of the water suction port 7 on the lower side of the water suction pipe 5 to meet the water drawing conditions. The present invention can drive the adjustment angle of the main water pipe 3 and the water distribution pipe 2 through the storage adjustment mechanism 8, and realize the angle adjustment and storage of the lower side water suction pipe 5, so that when the device is installed on the aircraft, the water drawing angle of the water suction pipe 5 and the water suction port 7 can be changed according to the water drawing terrain and the surrounding environment, thereby improving the application range and use efficiency of the device.

[0046] Working principle: The present invention sets water level sensors in the water tanks 1 on both sides, and then sets a control module and a battery assembly outside the water tanks 1. When the device draws water through the water suction port 7 at the lower end of the water suction pipe 5 according to the difference between the flight speed of the aircraft and the displacement of the water surface, and injects water into the water tanks 1 on both sides through the main water pipe 3, the diversion regulating mechanism 4 and the water diversion pipe 2, once there is an error in the water volume in the water tanks 1 on both sides, such as the water volume in the left water tank 1 is lower than that in the right water tank 1, the control module controls the micro motor 41 to rotate counterclockwise, thereby driving the transmission rod 48 and the spiral blade 49 to rotate. At the same time, the gear 1 461 meshing with the spiral blade 49 on the outside of the transmission rod 48 rotates, and the diverter plate 2 46 rotates clockwise inside the main water pipe 3 through the slide rail and the slide groove, and then the diverter port 1 45 on the left side gradually overlaps with the diverter port 2 47, and the aperture through which the water flows becomes larger, while the diverter port 1 45 on the right side gradually misaligns with the diverter port 2 47, and the aperture through which the water flows becomes smaller. Therefore, the amount of water flowing through the water diverter pipes 2 on both sides is adjusted and changed, thereby supplementing the water inlet of the left water tank 1, and achieving balanced water inlet of the water tanks 1 on both sides. Conversely, the micro motor 41 is driven in the reverse direction to rotate, and the right side is adjusted. The water tank 1 is replenished to adjust the water inflow through the water diversion pipes 2 on both sides. The wave-shaped diversion plate 43 evenly separates the water flowing through the diversion adjustment mechanism 4, and the wave-shaped diversion plate 43 can reduce the generation of water bubbles flowing through the water, and reduce the excess air in the water tank 1 from touching the red line. When working, since the device is installed on the aircraft, the water source environment, water flow and terrain changes will affect the water drawing efficiency. Therefore, by controlling the servo motor 82 to rotate, the connecting rod 81 is driven to rotate. At this time, the gear 2 84 connected to the connecting rod 81 is meshed with the gear 3 85, and the water is drawn. When the driving gear 3 85 rotates, the fixed shell 86 rotates, driving the water distribution pipe 2, the main water pipe 3 and the water suction pipe 5 fixed to the fixed shell 86 to rotate as a whole, thereby changing the angle of the water suction port 7 on the lower side of the water suction pipe 5 to meet the water drawing conditions. The present invention can drive the main water pipe 3 and the water distribution pipe 2 to adjust the angle through the storage adjustment mechanism 8, thereby achieving the angle adjustment and storage of the lower side water suction pipe 5, so that when the device is installed on an aircraft, the water drawing angle of the water suction pipe 5 and the water suction port 7 can be changed according to the water drawing terrain and the surrounding environment, thereby improving the application range and use efficiency of the device.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
