Description

Technical Field

[0001] This utility model relates to the field of drone rainmaking technology, specifically to a drone used for artificial rainmaking. Background Technology

[0002] In recent years, with the rapid development of drone technology, drones have been increasingly used in special scenarios such as search and rescue and rainmaking. In particular, drones can also be used to carry out artificial rainmaking operations. Artificial rainmaking is generally carried out by launching shells from helicopters. The cost of carrying out one artificial rainmaking operation is several million yuan, of which the cost of just deploying catalysts that directly act on the cloud layer is hundreds of thousands of yuan. The high cost prevents artificial rainmaking from being widely implemented.

[0003] The existing method involves using drones to carry rain-generating shells for artificial rainmaking. As the shells are launched, the drones move forward while the shells release the catalyst into the clouds.

[0004] Although the above equipment can induce artificial rain, the rain-spreading shells can only spread the catalyst in the direction of the drone's flight, and can only spread the catalyst in a small area. This requires multiple repetitions of spreading, which is quite time-consuming. Utility Model Content

[0005] In view of this, the present invention provides a drone for artificial rainmaking, which can release catalyst over a large area, reducing the need for drones to repeatedly spread catalyst.

[0006] To solve the above-mentioned technical problems, this utility model provides a drone for artificial rainmaking, including a drone with a pair of front wings on both sides. An internal cavity is provided inside the drone, containing a rainmaking catalyst storage box. Guide pipes are provided on both sides of the bottom of the rainmaking catalyst storage box, and the guide pipes are fixed to the bottom of the rainmaking catalyst storage box by flange rings. A ducting fan is provided on the side of each pair of front wings closest to the drone, and the ducting fans are fixed to the bottom of the pair of front wings by bolts. The suction port of the ducting fan is connected to one end of the guide pipe, and the suction force generated by the ducting fan draws the ducting fan into the guide pipe. Inside the drone, a conveying and dispersing assembly is located on the side of the induced flow fan. This assembly includes guide pipes positioned at the bottom of a pair of front wings. These guide pipes connect to the discharge port of the induced flow fan, allowing the fan to discharge the catalyst into the guide pipes. Multiple holes are laterally arranged on the arc-shaped surface at the bottom of the guide pipes, allowing the catalyst to fall through. A conveying component is installed inside the guide pipes to transport the catalyst within. Specifically, the rain-inducing catalyst is first loaded into a rain-inducing catalyst storage tank inside the drone. When the drone reaches the target area, the guide pipe at the bottom of the rain-inducing catalyst storage tank begins operation. At this time, the induced flow fan starts, using its powerful suction to draw the catalyst from the guide pipe. The drawn-in catalyst is then discharged by the induced flow fan into the guide pipe connected to its side. The guide tubes are located at the bottom of the front wings on both sides of the drone. They are designed with an arc-shaped surface and multiple holes arranged laterally. As the conveyor is driven, the catalyst moves in the guide tubes, is evenly dispersed, and falls continuously from these holes, releasing the catalyst over a large area and reducing the need for the drone to repeatedly spread the catalyst.

[0007] The conveying and dispersing assembly also includes a discharge pipe at the end of the guide pipe; that is, the catalyst that fails to be discharged in the guide pipe can be conveyed and discharged.

[0008] The conveying component also includes a spiral conveying plate disposed inside the guide tube. A rotating rod is disposed through the middle of the spiral conveying plate and is fixed to the spiral conveying plate by welding. One end of the rotating rod passes through the side wall of the feed pipe, thus facilitating the conveying of the catalyst by the spiral conveying plate.

[0009] The conveying component also includes a motor located near the feed pipe. The upper surface of the motor is fixed to the bottom of the front wing, and the output shaft of the motor is fixed to one end of the rotating rod; that is, the motor provides drive for the rotating rod.

[0010] The rain catalyst storage box is equipped with a V-shaped inclined plate, which is fixed inside the rain catalyst storage box by welding; this facilitates the sliding of the catalyst inside the rain catalyst storage box.

[0011] The outer surface of the rain catalyst storage box is equipped with a support plate, and the bottom of the support plate is fixed to the bottom of the inner cavity of the drone through a support column; thus providing support and stability for the rain catalyst storage box.

[0012] Two fixing blocks are provided at the bottom of the pair of forewings and are fixed to the bottom of the forewings by welding. The arc surfaces of the two fixing blocks are fixed to the arc surfaces of the guide tubes, and the arc surfaces on the fixing blocks are welded to the guide tubes; thus providing support for the guide tubes.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. Driven by a duct fan, suction is generated inside the feed pipe, indirectly drawing the catalyst from the catalyst storage tank into the feed pipe. The feed pipe then provides guidance, transporting the catalyst to the guide tube. The motor drives the rotating rod, which in turn drives the spiral conveyor plate, causing it to rotate within the guide tube. This ensures the catalyst is smoothly released from the orifices of the guide tube, allowing for large-area catalyst release.

[0015] 2. The rain catalyst storage box is equipped with a V-shaped inclined plate, which makes it easy for the rain catalyst to slide into the left and right side guide pipes, thus facilitating the continuous feeding of the rain catalyst. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown: This embodiment provides a drone for artificial rainmaking, including a drone 100. The drone 100 has a pair of forewings 101 on both sides. An inner cavity 102 is provided inside the drone 100, and a rainmaking catalyst storage box 103 is provided within the inner cavity 102. This rainmaking catalyst storage box 103 is used to store rainmaking catalysts, such as silver iodide. These catalysts can promote the condensation of water droplets in clouds, thereby triggering rainfall. Guide pipes 105 are provided on both sides of the bottom of the rainmaking catalyst storage box 103. The guide pipes 105 are installed at the bottom of the rainmaking catalyst storage box 103 via flanges. These pipes are responsible for guiding the catalyst inside the rainmaking catalyst storage box 103. A guide fan 106 is provided on the side of each pair of forewings 101 closest to the drone 100. The guide fans 106 are bolted to the forewings 101. The suction port of the guide fan 106 is connected to the guide fan... One end of the pipe 105 is connected to the feed pipe 105, which is responsible for drawing the catalyst in. The side end of the induced draft fan 106 is provided with a conveying and dispersing component 200. The conveying and dispersing component 200 includes a guide pipe 202 provided at the bottom of a pair of front wings 101. The guide pipe 202 is connected to the discharge port of the induced draft fan 106. The bottom arc surface of the guide pipe 202 is provided with multiple holes 201. These holes 201 allow the catalyst to be evenly dispersed into the cloud during flight. A conveying component 300 is provided inside the guide pipe 202. The conveying component 300 is used to convey the catalyst inside the guide pipe 202 and push the catalyst inside the guide pipe 202 to ensure that the catalyst can be released smoothly from the holes 201 of the guide pipe 202, thereby releasing the catalyst over a large area and reducing the need for the drone to repeatedly spread the catalyst.

[0027] First, the rain-reducing catalyst is loaded into the rain-reducing catalyst storage box 103 inside the drone 100. When the drone 100 reaches the target cloud area, the guide pipe 105 at the bottom of the rain-reducing catalyst storage box 103 starts working. The catalyst in the guide pipe 105 is drawn in by the powerful suction of the guide fan 106. The catalyst drawn in by the guide fan 106 enters the guide pipe 202 in the conveying and dispersing assembly 200. The conveying component 300 in the guide pipe 202 starts working, pushing the catalyst forward in the guide pipe 202. As the catalyst moves, it gradually approaches the multiple holes 201 on the arc-shaped surface at the bottom of the guide pipe 202. These holes 201 allow the catalyst to fall out from the holes 201 during the conveying process and fall into the cloud, thereby more effectively promoting the condensation of water droplets in the cloud.

[0028] Conveying and dispersing components 200 such Figure 4 As shown,

[0029] The conveying and dispersing assembly 200 also includes a discharge pipe 203 provided at the end of the guide pipe 202, through which catalyst that has not completely fallen out of the guide pipe 202 can be discharged.

[0030] Conveyor 300 Figure 5 As shown,

[0031] The conveying component 300 also includes a spiral conveying blade 301 disposed in the guide tube 202. A rotating rod 302 is disposed through the middle of the spiral conveying blade 301. One end of the rotating rod 302 passes through the side wall of the feed tube 203, so that the rotating rod 302 is welded and fixed to the spiral conveying blade. When the rotating rod 302 rotates, it can drive the spiral conveying blade 301 to rotate in the guide tube 202, thereby conveying the catalyst.

[0032] The conveyor 300 also includes a motor 303 disposed on the side near the feed pipe 203. The upper surface of the motor 303 is fixedly disposed with the bottom of the front wing 101. The output shaft of the motor 303 is fixedly disposed with one end of the rotating rod 302. The motor 303 provides drive for the rotating rod 302.

[0033] First, the outlet of the induced draft fan 106 discharges the catalyst into the guide tube 202. Then, the motor 303 drives the rotating rod 302, causing the rotating rod 302 to drive the spiral conveyor plate 301 to rotate within the guide tube 202, thereby promoting the catalyst within the guide tube 202.

[0034] Rainfall catalyst storage box 103 Figure 4 As shown,

[0035] The rain catalyst storage box 103 is equipped with a V-shaped inclined plate 107. The V-shaped inclined plate 107 is fixed to the center of the rain catalyst storage box 103 by welding, so that the rain catalyst can slide into the left and right guide pipes 105, thus facilitating the continuous feeding of the rain catalyst.

[0036] Rainfall catalyst storage box 103 Figure 4 As shown,

[0037] A support plate 104 is provided on the outer surface of the rain catalyst storage box 103. The support plate 104 is welded to the outer surface of the catalyst storage box. The bottom of the support plate 104 is fixed to the bottom of the inner cavity 102 of the drone 100 through a support column, thereby providing support for the support plate 104.

[0038] Fixed block 107 Figure 5 As shown,

[0039] Two fixing blocks 108 are provided at the bottom of a pair of front wings 101. The arc surfaces of the two fixing blocks 108 are fixedly set with the arc surfaces of the guide tube 202. The arc surfaces of the two fixing blocks 108 and the arc surfaces of the guide tube 202 are welded together, which facilitates the fixation and support of the guide tube 202.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
