[0026] As Figures 1-5 shown, an aircraft rain experiment device is proposed in an embodiment of the present application, including a control module, a water supply module 5 and a spray module; the above spray module includes a plurality of spray units; the above spray unit includes a seat body 1, a moving assembly 2 is arranged at the lower end of the seat body 1, a robotic arm assembly 3 is arranged at the upper end of the seat body 1, a spray assembly 4 is movably arranged at the upper end of the robotic arm assembly 3, and the water delivery end of the water supply module 5 is communicated with the spray assembly 4; the control module is used to control the start and stop of the water supply of the water supply module 5 and control the movement of the robotic arm assembly 3, and the spray assembly 4 adjusts the spray height and spray angle through the movement of the robotic arm assembly 3.

[0027] First of all, it should be stated that by freely moving the position of the moving assembly 2 of multiple spray units and adjusting the spray height and spray angle by the robotic arm assembly 3, the experimental state of aircraft of different specifications can be freely adjusted, and by adjusting according to the actual situation, it can be adapted to some aircraft with irregular shapes and large volumes for rain experiments, greatly improving the test application range; the volume of the entire experiment does not need to be adaptively designed according to the aircraft volume, reducing the space occupation of the entire device and reducing the transportation cost.

[0028] The above-mentioned robotic arm assembly 3 can be an existing hydraulic boom, which realizes lifting or attitude adjustment through multiple hydraulic mechanisms. Further, in order to simplify the structure of the entire robotic arm assembly 3 and thus reduce costs, the above-mentioned robotic arm assembly 3 includes a telescopic arm arranged at the upper end of the above-mentioned seat body 1. One end of the telescopic arm far from the above-mentioned seat body 1 is provided with a swing arm, and the above-mentioned spraying assembly 4 is arranged at one end of the swing arm far from the telescopic arm. Both the telescopic arm and the swing arm are electrically connected to the above-mentioned control module. It also includes a pneumatic driving device 8. The telescopic arm includes a pneumatic telescopic rod 31, the swing arm includes a cylinder 32, the telescopic end of the cylinder 32 is connected with a swing rod 33, and the swing rod 33 is rotatably connected to one end of the pneumatic telescopic rod 31 far from the above-mentioned seat body 1. The above-mentioned spraying assembly 4 is arranged at one end of the swing rod 33 far from the pneumatic telescopic rod 31; the output ends of the above-mentioned pneumatic driving device 8 are respectively connected to the pneumatic telescopic rod 31 and the cylinder 32; the above-mentioned pneumatic driving device 8 is used to respectively drive the pneumatic telescopic rod 31 and the cylinder 32 to achieve telescopic action; when the telescopic end of the cylinder 32 moves telescopically, it drives the swing rod 33 to swing relatively in the vertical plane; the above-mentioned pneumatic driving device 8 is electrically connected to the above-mentioned control module.

[0029] During operation, the control module controls the pneumatic device to drive and control the pneumatic telescopic rod 31 and the cylinder 32. The pneumatic telescopic rod 31 can be multiple telescopic rods, that is, formed by sequentially connecting multiple pneumatic cylinders to be multi-sectioned, and different connection angles are preset between the multiple telescopic rods, which can achieve the moving effect of extending from the side of the aircraft to the top of the aircraft; and the fixed end of the cylinder 32 is fixed to the pneumatic telescopic rod 31, and the telescopic end is hinged to the above-mentioned swing rod 33, and the middle of the above-mentioned swing rod 33 is hinged to the top of the pneumatic telescopic rod 31. When the cylinder 32 expands and contracts, it drives the swing rod 33 to rotate relative to the pneumatic telescopic rod 31 to realize the adjustment of the spraying angle; the telescopic structure realizes the adjustment of the spraying state of each spraying unit, simulating the rain test state under different weather conditions, and the pneumatic driving structure has the advantages of sensitive reaction and precise action, which is convenient for adjustment.

[0030] The above-mentioned water supply module 5 includes a water tank 51, the water tank 51 is communicated with a water pump 52, the water outlet end of the water pump 52 is communicated with a water supply pipe 53, a water valve is arranged on the water supply pipe 53, and the water supply pipe 53 is communicated with the above-mentioned spraying assembly 4; both the water pump 52 and the water valve are electrically connected to the above-mentioned control module. Moreover, a limiting structure for threading is arranged on the outer wall of the above-mentioned robotic arm assembly 3. When the height and angle of the robotic arm assembly 3 are adjusted, the water supply pipe 53 is pulled, and the water supply pipe 53 slides in the limiting structure, avoiding the situation that the water supply pipe 53 is stuck and broken when adjusting the robotic arm assembly 3. During operation, the control module controls the water pump 52 and the water valve to be normally opened, so that the water in the water tank 51 is pumped to the spraying assembly 4 under pressure, realizing fixed-angle and fixed-pressure spraying, and thus accurately simulating the state of the aircraft in the rain.

[0031] Moreover, to ensure real-time monitoring of the spraying state of the entire structure, the water supply module 5 is provided with a flow detection structure. By displaying the real-time spraying flow rate, the flow rate can be adjusted according to the actual situation to ensure the accuracy and stability of the entire experiment.

[0032] Among them, the spraying component 4 includes a nozzle arranged on the robotic arm component 3.

The automatic regulating valve is electrically connected to the control module; moreover, the nozzle is detachably arranged, and nozzles of different specifications and sizes can be replaced according to test requirements. Through the combined regulation of the water pump 52 and the automatic regulating valve, precise regulation of the spraying amount and spraying pressure is achieved, and the simulation of different state rainy days is realized.

[0033] In actual work, due to the excessive length of the water supply pipe 53, the water supply pipes 53 between multiple spraying units may become entangled with each other during the process of adjusting the position. To avoid the occurrence of the above situation, multiple reelers 7 are further included. The multiple reelers 7 correspond to the multiple spraying units one by one. The reelers 7 are used to reel in the water supply pipes 53 of the corresponding spraying units. The reelers 7 can be electric.

[0034] The control module includes a control panel 6 arranged on the base 1. A plurality of control buttons are arranged on the control panel 6. The control buttons are electrically connected to the PLC board. By pressing the control buttons, adaptive control of the robotic arm component 3, the water supply module 5, and the spraying component 4 is achieved.

The support columns 22 are used to adjust the height and then abut against the ground to position the base 1. The support columns 22 can stably achieve the positioning and supporting effect of the entire structure. After moving the entire spraying unit to the designated position, the support columns 22 are adjusted to abut against the ground to prevent the spraying unit from moving randomly and improve the stability during work.

The spray system is designed modularly, and the requirements of rainfall intensity and rainfall uniformity are comprehensively considered. The nozzles are selected, and a plurality of spray unit components are combined together according to the size of the spray surface to form a spray array to realize modular spraying. And to ensure the spraying uniformity, it is necessary to reasonably distribute each spray system module, so as to achieve a full coverage of the spray surface, and it is possible to realize the rain shower test of rainfall environment simulation for various sizes of aircraft and different parts.
