A first protective plate 112 is rotatably connected to the top of the two first hinges 111. A protective airbag 113 is fixedly installed around the inside of the test protection box 101. The lifting motor 104 drives the sprocket transmission assembly 105 and the lifting threaded rod 106 to rotate, so that the lifting threaded sleeve 107 drives the test bench body 108 to move up and down. This can move the concrete component to be exploded into the inside of the test protection box 101. At the same time, under the action of the first hinge 111, the first protective plate 112 is retracted into the inside of the test protection box 101 to provide initial protection for the test protection box 101. The protective airbag 113 inside the test protection box 101 provides secondary protection for the test protection box 101, further improving the safety of the static explosion experiment.

The elastic force of the second protective spring 210 can effectively reduce the impact force generated by the explosion, thereby improving the protective effect of the protective cover 211.

[0033] Working principle: Before using this static explosion test stand with safety protection functions, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6As shown, firstly, the concrete component to be tested in the explosion experiment is placed on top of the test bench body 108. The lifting motor 104 drives the sprocket transmission assembly 105 and the lifting threaded rod 106 to rotate, causing the lifting threaded sleeve 107 to move the test bench body 108 up and down. This moves the concrete component to be exploded into the interior of the test protective chamber 101. Simultaneously, under the action of the first hinge 111, the first protective plate 112 retracts into the interior of the test protective chamber 101, providing initial protection. The protective airbag 113 inside the test protective chamber 101 provides secondary protection, further improving the safety of the static explosion experiment. Secondly, during the retraction and descent of the first protective plate 112, the first connecting support 118 and the connecting spring... Spring 119 and the second connecting support 120 can drive the protective cover 115 to rotate, thus sealing the test protective chamber 101. The top of the test protective chamber 101 is protected by the first buffer spring 116 and the second protective plate 117, improving the safety of the explosion experiment. Finally, the protective motor 204 drives the protective rotating rod 205 and the bevel gear transmission assembly 206 to rotate, causing the bevel gear transmission assembly 206 to drive the protective threaded rod 207 to rotate. At the same time, the protective threaded sleeve 208 drives the protective lifting plate 209 to move up and down, lowering the protective cover 211 to the outside of the test protective chamber 101, thereby protecting the test protective chamber 101. The elastic force of the second protective spring 210 can effectively reduce the impact force generated by the explosion, thereby improving the protective effect of the protective cover 211.
