Embodiment 1

[0040] When the safety performance of the positive pressure protective clothing is dynamically tested in a bioaerosol environment, the simulated motion detection dummy 6 is first removed from the auxiliary motion platform 44, and the positive pressure protective clothing to be tested is placed on the simulated motion detection On the dummy 6, the positive pressure protective clothing has a hole of the same size at the first sealing disc 17, the first sealing disc 17 passes through this hole and is connected with the suspension system 23 and tightens the second sealing disc to compress the protective The clothing realizes sealing, and the limbs of the simulated motion detection dummy 6 are connected and fixed by the fixed plate 27 on the swing arm 29 and the Velcro 28. Open the positive pressure protective clothing air supply system, open the control system and adjust the swing arm 29 to get back to zero. Open the mixing fan 30, close the inflatable airtight door 14 of the airt...

Embodiment 2

[0042] When dynamically testing the safety performance of protective clothing in a liquid spray environment, first check the water-absorbent indicator clothing and protective clothing to ensure that they are completely dry. Put the water-absorbent indicating clothing on the simulated spray test dummy 5. After putting on the protective clothing, the feet of the simulated spray detection dummy 5 are fixed on the turntable 37 . Close the inflatable airtight door 14 on the airtight experimental chamber 34, turn on the control system, the turntable 37 automatically rotates to the baseline position, the spray solenoid valve opens, the baseline position spraying starts, and the automatic timing is 15 minutes. After the time is up, the spraying stops, the spraying solenoid valve is closed, the turntable 37 rotates at an angle of 45°, the spraying system is started again, and the spraying is continued for 15 minutes. The turntable 37 takes 45° as the rotation angle, and rotates to 4 p...

Abstract

The invention discloses a positive-pressure protection suit dynamic detection platform. The positive-pressure protection suit dynamic detection platform comprises an airtight experiment cabin, a simulated motion detection dummy, a simulated spraying detection dummy, an auxiliary motion platform and a control system, wherein the auxiliary motion platform is arranged in the airtight experiment cabin; the simulated motion detection dummy is connected to the auxiliary motion platform; the simulated spraying detection dummy is connected to a rotating disk in the airtight experiment cabin; a spraying system and a ventilation system are arranged in the airtight experiment cabin; the control system is arranged outside the airtight experiment cabin, and is connected with the airtight experiment cabin. By adopting the positive-pressure protection suit dynamic detection platform disclosed by the invention, harm to the health of a real person caused by experiments can be avoided, the simulation accuracy is increased, pressure fluctuation inside a protection suit can be detected in real time, biological aerosol can be sampled in order to detect the safety performance of the biological aerosol, and more accurate detection results and more reliable data area achieved.

Description

technical field [0001] The invention relates to the technical field of protective clothing safety detection, in particular to a dynamic detection platform for positive pressure protective clothing. Background technique [0002] Medical workers and scientific researchers engaged in research on severe infectious diseases are often exposed to high-risk biological contamination environments. Staff need to wear protective clothing to ensure they are not harmed. Among them, positive pressure protective clothing is one of the personal protective equipment with the highest protection factor. Safety performance and thermal comfort are two important indicators of positive pressure protective clothing, which are related to the life and health, work efficiency and accuracy of operators. [0003] Most of the currently developed positive pressure biological protective clothing adopts or improves the design of the old positive pressure protective clothing, and whether its safety performanc...
