[0023] The features and performance of the jet-type integrated wind and rain simulation device of this application will be further described in detail below with reference to the embodiments.

[0024] Example 1 like Figure 1 , Figure 2 and Figure 3As shown in the figure, this application embodiment provides a jet-type integrated wind and rain simulation device, which includes a bottom support 100 and a fan 140. Angle steel 101 is connected to the four corners of the bottom of the bottom support 100. Each angle steel 101 is connected to two fixing bolts 102 for connecting it to the ground. A connecting flange 103 is connected to the top surface of the bottom support 100. A support seat 110 is connected to the top of the connecting flange 103 by six bolts arranged at intervals along its circumference. A rotating seat 120 is connected to the top of the support seat 110. A U-shaped fan bracket 130 is connected to the top of the rotating seat 120. Two coaxially arranged rotating shafts 141 are connected to the two sides of the fan 140. The two rotating shafts 141 are rotatably connected to the two ends of the fan bracket 130. An annular spray pipe 150 is connected to the air outlet of the fan 140. The spray pipe 150 is coaxially arranged with the air outlet of the fan 140. Spray holes arranged at intervals along the circumference are provided on the inner side of the spray pipe 150.

[0025] A water pump 160 is connected to the bottom of the bottom support 100. The inlet of the water pump 160 is connected to the inlet pipe 170 through a 6-point male thread double thread direct connector. The inlet pipe 170 is connected to the filter 220. The outlet of the water pump 160 is connected to the outlet pipe 190 through a 6-point thread elbow. The outlet pipe 190 is connected to the spray pipe 150. A flow control valve 180, a heater 200 and a temperature sensor 210 are sequentially arranged on the outlet pipe 190 away from the water pump 160.

[0026] The jet-type wind and rain simulation integrated device provided in this application embodiment uses a water pump 160 to introduce water from an external water source through an inlet pipe 170 and an outlet pipe 190 into an annular spray pipe 150 connected to the air outlet of a fan 140. This causes water to spray out from spray holes opened on the inner wall of the spray pipe 150. The air generated by the fan 140 blows the water droplets sprayed from the spray holes on the spray pipe 150 forward to create a wind and rain environment for drone testing. The flow control valve 180 set on the outlet pipe 190 can control the flow rate of water flowing through the outlet pipe 190 into the spray pipe 150 to control the amount of droplets sprayed through the spray holes. The heater 200 heats the water flowing through the outlet pipe 190 into the spray pipe 150, and the temperature sensor 210 detects the temperature of the water flowing through the outlet pipe 190 into the spray pipe 150, thereby controlling the temperature of the water droplets sprayed from the spray holes on the spray pipe 150 and simulating the effect of water droplets of different temperatures on the flight of the drone.

[0027] In addition, the inlet pipe 170 is connected to a filter 220 to filter the water entering the water pump 160, preventing large particles in the water from damaging the water pump 160. Angle steel 101 is connected to each of the four corners of the bottom support 100. Each angle steel 101 is connected to two fixing bolts 102 for connecting it to the ground. The fixing bolts 102 connected to the angle steel 101 can stably fix the bottom support 100 to the ground, improving the operational stability of the jet-type wind and rain simulation integrated device. A U-shaped fan bracket 130 is connected to the top of the rotating base 120. The two sides of the fan 140 are connected to the two ends of the fan bracket 130 via rotating shafts 141 that can rotate around a horizontal axis. This allows operators to easily control the fan 140 to rotate relative to the fan bracket 130 in a vertical plane to adjust the pitch angle for testing wind and rain spraying in areas at different heights. The rotating base 120 connected to the bottom of the fan bracket 130 is bolted to the connecting flange 103 via a support base 110. Operators can loosen the bolts and rotate around the fan bracket 130 to test the spraying of wind and rain. After the vertical axis rotating support 110, rotating seat 120, fan bracket 130 and fan 140 are rotated to a preset angle, the support 110 is reconnected to the connecting flange 103 using bolts. The preset angle can be 60 degrees, 120 degrees, 180 degrees and 240 degrees, so that the operator can easily control the fan 140, fan bracket 130 and rotating seat 120 to rotate relative to the support 110 around the vertical axis to adjust the direction of the fan 140 to spray wind and rain in different areas for testing.

[0028] In other alternative embodiments, the jet-type wind and rain simulation integrated device may also include a water tank connected to the filter 220 via a hose and a refrigeration unit connected to the water tank. The refrigeration unit is used to cool the water before it is introduced into the water tank, so that the water in the water tank passes through the filter 220 and enters the inlet pipe 170, the water pump 160 and the outlet pipe 190 and is then sprayed into the annular spray pipe 150 connected to the air outlet of the fan 140, thereby simulating the impact of water droplets with a wider temperature range on the flight of the drone.

[0029] Example 2 like Figure 4 , Figure 5 and Figure 6 As shown, this application provides a jet-type integrated wind and rain simulation device, which has a structure that is roughly the same as the jet-type integrated wind and rain simulation device provided in Embodiment 1. The difference is that in this embodiment, a square adjustment frame 230 and three square adjustment screens 240 are provided on the outer side in front of the air outlet of the fan 140. The mesh diameter of the three adjustment screens 240 increases from small to large. One of the adjustment screens 240 is detachably connected to the adjustment frame 230 to adjust the size of the raindrops sprayed from the air outlet of the fan 140.

[0030] The top of the fan 140 is connected to an L-shaped support rod 250. The end of the support rod 250 away from the fan 140 is connected to a vertically arranged threaded sleeve 280. The threaded sleeve 280 is connected to a screw 290 by threads. The bottom of the screw 290 is connected to a ball seat 260. The ball seat 260 is connected to a rotatable ball head 270 through a ball groove 261. The top of the adjusting frame 230 is connected to the ball head 270 through a connecting column.

[0031] An annular mounting groove 300 is formed by an indentation on the inner side of the surface of the adjusting frame 230 away from the fan 140. An annular mounting plate 310 is provided in the mounting groove 300. The mounting plate 310 is used to press and fix the outer edge of the adjusting screen 240 into the mounting groove 300. Eight limiting bolts 320 are also connected to the outer wall of the mounting groove 300. The eight limiting bolts 320 are arranged at intervals along the circumference of the mounting groove 300 to press and limit the position of the mounting plate 310.

[0032] The jet-type integrated wind and rain simulation device provided in this application embodiment blocks and filters raindrops sprayed from the air outlet of the fan 140 by setting an adjustment frame 230 connected to an adjustment screen 240 on the outer side in front of the air outlet of the fan 140. At the same time, the operator can replace the adjustment screen 240 with different screen sizes and connect it to the adjustment frame 230 to form raindrops of different sizes to conduct flight tests on the drone, thereby testing the flight performance of the drone under different intensities of rain. The top of the fan 140 is connected to a vertically arranged threaded sleeve 280 via a support rod 250. The threaded sleeve 280 is threadedly connected to a screw 290. The bottom of the screw 290 is connected to a ball seat 260. The ball seat 260 is connected to a rotatable ball head 270 via a ball groove 261. The top of the adjusting frame 230 is connected to the ball head 270 via a connecting post. When the operator adjusts the pitch angle of the fan 140, the operator can rotate the screw 290 so that the screw 290 moves along the threaded sleeve 280. The height of the ball seat 260, ball head 270 and adjusting frame 230 is adjusted by moving the ball 80, so that the adjusting screen 240 connected to the adjusting frame 230 is aligned with the air outlet of the fan 140 at different pitch angles. At the same time, the top of the adjusting frame 230 is rotatably connected to the ball groove 261 on the ball seat 260 at the bottom of the screw 290 via the ball head 270. This allows the operator to easily rotate the ball head 270 relative to the ball seat 260 to adjust the angle of the adjusting frame 230 to adapt it to the air outlet of the fan 140.

[0033] An annular mounting groove 300 is formed by the inner recess of the surface of the adjusting frame 230 away from the fan 140. The operator can place the adjusting screen 240 on the surface of the adjusting frame 230 away from the fan 140, and make the four sides of the adjusting screen 240 respectively located in the annular mounting groove 300. The annular mounting plate 310 is placed into the mounting groove 300 to press and fix the four sides of the adjusting screen 240 into the mounting groove 300. Then, eight limiting bolts 320 are connected to the outer wall of the mounting groove 300 respectively. The eight limiting bolts 320 are used to press and limit the position of the mounting plate 310, so that the mounting plate 310 presses and fixes the adjusting screen 240 into the mounting groove 300 for stable testing.
