The state of the suit is comprehensively photographed, and the control device controls the connection and identification camera to obtain the status image of the protective suit entering the water obtained by the identification camera, and automatically identifies it to identify whether the protective suit immersed in the water has corresponding blisters. , to test the waterproof performance of protective clothing.

Here is a further description of the process of using the waterproof performance testing device with such a structure to test the waterproof performance of the protective clothing.

First fill the water storage device in the test device with the required amount of water.

Then, the main part of the protective suit to be tested is placed in the water storage device, and the opening part is connected and matched with the inflatable device through the clamping device.

Then, the inflation device is controlled to inflate the protective clothing to form a certain air pressure in the protective clothing to form a test state.

Then, when the air pressure in the protective suit reaches the requirement, the inflation device is controlled to stop inflating, and the clamping device is controlled to clamp the opening of the protective suit for sealing. At this time, the inflatable protective suit floats horizontally on the water surface of the water storage device as a whole.

Next, after the clamping device clamps and seals, the pressing device moves toward the protective clothing on the water storage device until the entire protective clothing is horizontally pressed into the water. This can ensure that the air pressure inside the protective clothing entering the water is relatively balanced, thereby improving the accuracy of later detection. The depth of pressing into the water depends on the test requirements and is not limited here.

Finally, the identification device performs real-time monitoring and identification of the state of the protective clothing that is inflated inside and immersed in water as a whole, so as to identify the state of bubbles generated by the protective clothing. As an example, whether the protective clothing has blisters and the state of the blisters are identified here, thereby judging the waterproof performance of the protective clothing.

In addition, according to the need, the device can be identified by the naked eye without using the identification device, which can also achieve the effect of rapid detection.
