[0018] like Figure 1 The figure shows a specific embodiment of a test device for evaluating the protective performance of explosive ordnance disposal equipment according to the present invention. The test device comprises a data acquisition module, a protective assembly, and a dummy lifting platform. The protective assembly is used to install explosion-proof glass, and the dummy lifting platform is used to install a dummy. The dummy is used to test explosive ordnance disposal equipment. The data acquisition module includes a display 1, a controller 2, and a sensor mounted on the dummy. The controller 2 is used to control the explosives, and the sensor is used to detect the impact pressure of the dummy when it is subjected to the blast wave. The display 1 is used to display the impact pressure. The dummy lifting platform is located on one side of the protective assembly and includes a dummy base 11, a crossbeam 13, and a telescopic bracket 14. The dummy base 11 has threaded holes 12 for securing the dummy. The crossbeam 13 is located below the dummy base 11, and the telescopic bracket 14 is located below the crossbeam 13. An upwardly extending lever 10 is located on one side of the dummy base 11. The telescopic bracket 14 can be fixed at different heights using a pin 15 to a perforated metal plate to achieve a telescopic function. During the test, bomb disposal equipment is used in conjunction with a dummy. Sensors are used to detect the impact force of the dummy during the explosion and visually inspect the degree of surface damage on the dummy.

[0019] There is a preset distance between the crossbeam 13 and the dummy base 11 so that the dummy can be installed through the threaded hole 12. A pulley 16 is provided at the bottom end of the telescopic bracket 14 to facilitate movement and position adjustment.

[0020] like Figure 1 As shown, the protective assembly includes a protective frame 8 and a telescopic rod 7. The protective frame 8 is used to install the bulletproof glass 9. The telescopic rod 7 is horizontally installed at the top of the protective frame 8. The end of the telescopic rod 7 is connected to the explosive tray 5 through a flexible member 6. The flexible member 6 can be a thin rope. The controller 2 is connected to the explosive tray 5 through a connecting line 17.

[0021] The display 1 and the controller 2 are integrated in a control cabinet, and the control cabinet is arranged on the other side of the protective component.

[0022] The control cabinet is provided with a folding rod 3, and the folding rod 3 has a vertical support rod and a horizontal support rod. The bottom end of the vertical support rod is connected to the control cabinet, and the top end of the vertical support rod is connected to the horizontal support rod. The horizontal support rod is provided with a rangefinder 4, which can slide on the horizontal support rod. The rangefinder 4 can be an infrared sight or a telescopic steel ruler, which is used to measure the distance between the explosives and the test equipment to evaluate the impact force of different distances on the bomb disposal equipment.

[0023] When using the test device for evaluating the protective performance of bomb disposal equipment of the present invention for testing, the control cabinet and the dummy lifting platform are placed on both sides of the protective component, the length of the thin rope is adjusted so that the explosives tray and the explosives are suspended at a height of 1m from the ground, and the bolts at the bottom of the dummy are installed in the threaded holes in the dummy lifting platform. At this time, the bottom part of the dummy is embedded in the dummy base, and the baffle has a certain supporting effect on the dummy. The height of the telescopic bracket and the rolling pulley are adjusted so that the line of sight of the dummy's eyes is directed to the explosives or the midpoint of the sensitive surfaces of the two pressure sensors installed horizontally and symmetrically at the lower end of the dummy's sternum is 3m±0.01m away from the explosives in a straight line. The bomb disposal equipment is worn on the dummy, and after the test system is debugged and tested, the controller is started to trigger the explosion of the explosive. The impact of the explosive acts on the sensor through the protective component and the bomb disposal equipment in turn, the impact force value of the dummy is obtained, the curve collected by the sensor is recorded, and the degree of surface damage of the dummy is visually inspected.

[0024] The utility model provides a test device for evaluating the protective performance of bomb disposal equipment, which can reduce costs, simplify procedures, provide a support seat for a dummy, and has a simple structure, convenient operation, and reliable testing.
