[0014] The present invention provides a device for detecting the anti-penetration of waterproof membranes for building roofs. The device has the following beneficial effects: (1) The invention can detect the penetration of the bottom of the waterproof roll material through the camera in the detection module. When the telescopic rod moves downward, the telescopic rod can drive the circular plate to move downward. When the circular plate moves downward, the circular plate will drive the pressure plate to move downward. When the pressure plate moves downward, the pressure plate can press the waterproof roll material to prevent the waterproof roll material from deviating and affecting the test results. When the triangular inclined block moves downward, the triangular inclined block will drive the scraper to scrape the upper surface of the waterproof roll material. When the scraper scrapes the upper surface of the waterproof roll material, the scraper can clean the impurities on the top of the waterproof roll material. When the triangular inclined block moves upward, the triangular inclined block will break away from the contact with the scraper. At this time, the scraper will return to its original position under the elastic force of spring 2. When the scraper returns to its original position, the scraper will clean the rainwater on the top of the waterproof roll material, which can prevent the sulfuric acid and nitric acid in the water from being harmful to the human body.

[0015] (2) In the invention, when the rotating plate is pushed downward by the short plate, the rotating plate will drive the supporting rod to rotate. When the supporting rod rotates, the supporting rod will drive the long roller to rotate. When the long roller rotates, the long roller will pull the waterproof membrane to both sides to prevent wrinkles from forming and causing rainwater accumulation to affect the test results. When the cross bar contacts the waterproof membrane, the cross bar can fix the middle part of the waterproof membrane. When the long roller rotates, it can prevent the long roller from pulling the waterproof membrane to one side and prevent the position of the waterproof membrane from shifting.

[0016] (3) In this invention, when the circular notches on the upper and lower surfaces of the skateboard coincide with the cross-section of the water extraction pipe, the precipitation module will extract the water at the bottom inside the machine body. After the precipitation module extracts water, precipitation will occur to detect the anti-permeability. By rotating the long roller to drive the start of the precipitation module, it can effectively prevent the test results from being affected when the anti-crease pulling is not completed. When sulfuric acid and nitric acid liquids are incorporated into the water inside the machine body, the acidity and alkalinity of the water can be increased to mimic acid rain, and the anti-dissolubility of the waterproof coiled material can be tested.
