Description

Technical Field

[0001] The utility model relates to the technical field of leak testing devices, in particular to a leak testing device for detecting waterproof coiled materials. Background Art

[0002] In the construction industry, the sealing and waterproofness of waterproof membranes are important factors to ensure the safety of building structures and extend their service life. Therefore, in real life, waterproof membranes are effectively tested through leak testing devices. Leak testing devices for waterproof membrane testing usually include components such as closed containers, pressure sensors, high-pressure air sources, data acquisition and analysis systems, and lighting devices. However, when most of the existing leak testing devices test the leakage of waterproof membranes, water can easily seep out from the contact point between the waterproof membrane and the test device, resulting in poor waterproof sealing effect, which in turn causes the test device to be unable to accurately obtain the leakage test results of the waterproof membrane.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN219474894U proposes a waterproof membrane leak test device, which spreads the cut waterproof membrane flat on the top surface of the test tube, drives the pressurized tube and the test tube close to each other through the lifting component to initially clamp the waterproof membrane, and then inflates the annular airbag through an external air source to expand it. The inflated annular airbag presses the waterproof membrane to be tested tightly against the inner wall of the annular groove to complete the secondary clamping, and then the lifting component drives the pressurized tube and the test tube to be close to each other to complete the final clamping, thereby improving the overall sealing effect.

[0004] However, although the above-mentioned waterproof roll material leak test device can improve the sealing between the pressurizing cylinder and the test cylinder by adding an annular airbag, the waterproof roll material leak test device can only detect a single piece of waterproof roll material at a time. When there are many waterproof roll materials that need to be tested, it takes a lot of time, resulting in low efficiency in waterproof roll material detection. Therefore, the utility model provides a leak test device for waterproof roll material detection to meet the demand. Utility Model Content

[0032] like Figures 1 to 6 As shown, an embodiment of the utility model provides a leak test device for detecting waterproof coiled materials, including a cylinder 1, a cylinder cover 2 being detachably connected to the top thereof, a fixed column 5 being provided at the center inside the cylinder 1, a plurality of slide rods 14 being provided along the circumference direction of the fixed column 5, an inspection port 3 being equal to the slide rod 14 penetrating the cylinder 1 relative to the slide rod 14, a clamping groove 20 connected to the inspection port 3 being provided in the cylinder 1, a plurality of sliding sleeves 15 being respectively sleeved and slidably provided on the plurality of slide rods 14, a plurality of connecting rods 16 being provided on the sliding sleeve 15 along the circumference direction thereof, a clamping ring 17 being provided at one end of the plurality of connecting rods 16 facing away from the sliding sleeve 15 and being capable of limiting the coiled material 18 in the clamping groove 20, and a driving component 9 for driving the sliding sleeve 15 to slide along the sliding rod 14 being provided in the cylinder 1.

[0033] Specifically, the coils 18 to be tested are placed into the clamping groove 20 in sequence, and then the driving assembly 9 drives the multiple sliding sleeves 15 to move along the sliding rod 14 toward the clamping groove 20, so that the clamping ring 17 presses the coils 18 to the clamping groove 20. At this time, the positioning of the multiple coils 18 is achieved, and then water is added to the cylinder 1, and the cylinder cover 2 is connected and sealed to the cylinder 1. After that, the coils 18 can be tested by external equipment. The overall operation is simple, and it is easy to realize the simultaneous testing of multiple coils 18, which saves the testing time and improves the testing efficiency. It solves the problem that the existing waterproof coil leak testing device can only test a single piece of waterproof coil at a time. When there are many waterproof coils to be tested, it takes a lot of time, resulting in low efficiency in waterproof coil testing.

[0034] It should be noted that when inspecting the coil 18 in the cylinder 1, the probe of the pressure sensor can be inserted into the cylinder 1 by penetrating the cylinder cover 2. At the same time, the through pipe of the external pressurizing device can be inserted into the cylinder 1 by penetrating the cylinder cover 2, and gas can be injected into the container through the pressurizing device to increase the water pressure in the container to the set value. The pressure sensor monitors the water pressure change in real time and transmits the data to the data acquisition and analysis system. Once an abnormal pressure drop is detected, it indicates that there is a leak point. At the same time, the lighting device is started to illuminate the suspected leakage area of ​​the detection port for easy observation and recording. The leakage position of the waterproof coil can be accurately found through data comparison and image recording of the analysis system. The installation and connection methods of the above detection equipment are all existing technologies. For details, please refer to the Chinese patent with announcement number CN219474894U, which proposes a waterproof coil leak test device, which will not be described in detail here.

The overall operation is simple, and it is easy to realize the simultaneous testing of multiple coils 18, which saves the testing time and improves the testing efficiency. It solves the problem that the existing waterproof coil leak testing device can only test a single piece of waterproof coil at a time.
