Description

Technical Field

[0002] With the development of digital construction, space-time information, positioning and navigation services have become important new infrastructures, and the Beidou navigation satellite system has become a major strategic space-time infrastructure for various countries. At present, drone inspections in the power industry mainly rely on the Beidou navigation system for navigation and positioning, and use the Beidou ground-based augmentation system to provide drones with real-time centimeter-level location information and navigation and positioning.

[0003] As an important part of the drone, the mechanical properties of the control panel are directly related to the flight stability and safety of the drone. By conducting mechanical performance tests, the performance of the control panel when subjected to various mechanical stresses, including compression and tension resistance, can be evaluated. This helps ensure that the control panel will not fail under extreme flight conditions, thereby ensuring the flight safety of the drone.

[0004] When the control panel is tested for mechanical properties, in addition to tensile and extrusion tests, a pressure test is also required to determine the pressure resistance of the control panel. Since the control panel can only be tested at a single angle during the pressure test, some mechanical stress problems that only occur at specific angles will be missed, making it impossible to fully evaluate the mechanical properties of the control panel. Moreover, due to the limitation of the test angle, it may not cover all kinds of mechanical stress conditions that the control panel can withstand in actual use, which will cause some potential performance problems or safety hazards to be ignored, resulting in low accuracy of the test results. Summary of the invention

[0031] In the present invention, the test device is placed and fixed by the base 1, and the control panel of the drone to be tested is clamped and fixed by the first clamp 3 and the second clamp 5, and then the first hydraulic cylinder 43 arranged on the positioning plate 41 through the mounting frame 42 drives the second clamp 5 to move, so that the control panel between the first clamp 3 and the second clamp 5 is stretched, and the tensile force gauge 10 between the second clamp 5 and the output end of the driving component 4 can detect the tension data of the control panel during tensile deformation. When performing a pressure test on the control panel, the control panel to be tested is clamped and stabilized by the first clamp 3 and the second clamp 5, and then the power component 6 is used to adjust the lateral position of the pressure test component 9, and then the angle of the pressure test component 9 is adjusted by the cooperation of the mounting plate 8 and the bracket plate 7, so that the mechanical properties of the drone control panel under different force directions and angles can be comprehensively tested, and the pressure test component 9 performs a pressure test on the control panel.

[0032] Among them, Figure 2 and Figure 6As shown, the pressure testing assembly 9 includes a second hydraulic cylinder 91 arranged on the mounting plate 8, and a top head 93 is arranged on the output end of the second hydraulic cylinder 91 through a pressure gauge 92, and a connecting sleeve 921 is arranged on the pressure gauge 92. The top head 93 is detachably connected to the connecting sleeve 921 through a threaded end 931. When performing a pressure resistance test on the control panel of the drone, the second hydraulic cylinder 91 drives the top head 93 to press on the control panel to be tested. The pressure data of the control panel when it is deformed can be detected by the pressure gauge 92, so as to detect its pressure resistance. The top head 93 is screwed on the connecting sleeve 921 through the threaded end 931, which can facilitate the disassembly and installation of the top head 93, so that different top heads 93 can be conveniently replaced during testing to detect the pressure resistance of the control panel under different pressure structures.

[0033] It should be noted that if Figure 1 and Figure 8 As shown, the structures of the first clamp 3 and the second clamp 5 are the same. Both clamps include a fixing frame 31, on which a clamping plate 33 is provided through a screw 32, and a handle 34 is provided on the top of the screw 32. When clamping the control panel to be tested, the control panel is first placed on the fixing frame 31, and then the screw 32 is rotated by the handle 34 to move the clamping plate 33, thereby cooperating with the fixing frame 31 to clamp and fix the control panel to be tested.

At this time, rotate the positioning plate 82, so that the positioning plate 82 drives the mounting plate 8 to rotate through the connecting rod 81 to adjust the angle of the pressure test assembly 9 on the mounting plate 8. After the angle of the pressure test assembly 9 is adjusted, the positioning bolt 722 is passed through the positioning hole 83 of the positioning plate 82 at the corresponding position and then screwed onto the bracket plate 7 to achieve the adjustment of the angle of the pressure test assembly 9.

[0037] Among them, the bracket plate 7 is detachably mounted on the slide 64, and the motor 62 on the fixed plate 61 drives the screw 63 to rotate so that the slide 64 can move linearly on the screw 63, thereby driving the pressure test assembly 9 to move. After the control panel to be tested is clamped and fixed by the first clamp 3 and the second clamp 5, the power assembly 6 can drive the pressure test assembly 9 to move linearly, so that the pressure resistance test can be performed on different positions of the control panel to be tested, thereby improving the accuracy of the test results.
