[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A device for detecting the waterproofness of oil-resistant and water-repellent polyester-cotton fabrics comprises a support frame 1, the upper end of the support frame 1 is fixedly connected to a liquid storage tank 2, the front end of the support frame 1 is sleeved with a transparent protective frame 3, the upper frame wall inside the support frame 1 is fixedly connected to a No. 1 cylinder 4, the output end of the No. 1 cylinder 4 is fixedly connected to a humidity detection sensor 6, the upper frame wall inside the support frame 1 is fixedly connected to two high-pressure nozzles 5, the lower ends of the two high-pressure nozzles 5 are both passed through and fixedly connected to a high-pressure nozzle 7, the No. 1 cylinder 4 is located between the two high-pressure nozzles 5, and the rear part of the upper frame wall inside the support frame 1 is fixedly connected to a support assembly 8.

[0028] In this embodiment, the support frame 1 includes a frame body 11, a card slot 13 is opened at the front upper end of the frame body 11, two insertion rods 14 are fixedly connected to the lower groove wall of the card slot 13, and two sliding grooves 12 are opened on the left groove wall and the right groove wall of the frame body 11. The frame body 11 is fixedly connected to the support assembly 8; the two insertion rods 14 are both connected with the transparent protective frame 3 through the card slot 13 and the transparent protective frame 3 is sleeved; the liquid storage tank 2 is connected with the two high-pressure nozzles 5 through a pipeline.

[0029] Through the above scheme: the support assembly 8 is supported by setting a support frame 1, and the support frame 1 contains water for testing. The two sets of two horizontal slide grooves 12 can provide limit support for the height adjustment process of the support assembly 8. The two insertion rods 14 are connected to the transparent protective frame 3 through an interlaced connection, and the transparent protective frame 3 is connected to the card slot 13 through an interlaced connection. The transparent protective frame 3 can be positioned to protect the water sprinkling process, avoid splashing of the testing water during the detection process, and improve safety.

[0030] In this embodiment, the support assembly 8 includes a No. 2 cylinder 81, and the output end of the No. 2 cylinder 81 is fixedly connected to a connecting frame 82. Two sliders 83 are fixedly connected to the upper left end and the upper right end of the connecting frame 82. A groove 84 is opened on the lower frame wall inside the connecting frame 82. The four corners of the upper end of the connecting frame 82 are all inserted and connected with limiting screws 85. The No. 2 cylinder 81 is fixedly connected to the support frame 1; the four sliders 83 are respectively inserted and connected with the four slide grooves 12.

[0031] Through the above scheme: the polyester-cotton fabric is supported and positioned by the support component 8, the polyester-cotton fabric to be tested is placed in the groove 84, and the four limiting screws 85 pass through the connecting frame 82 and contact the polyester-cotton fabric placed in the groove 84, so that the polyester-cotton fabric can be positioned and the stability is improved.

[0032] It should be noted that the present invention is a device for detecting the waterproofness of oil-resistant and water-repellent polyester-cotton fabrics. During use, first, the oil-resistant and water-repellent polyester-cotton fabric to be tested is placed at a specific position of the detection device (such as in the groove 84), so that the fabric naturally forms a concave shape. This shape helps to better simulate the waterproof effect in actual use scenarios. Subsequently, four limiting screws 85 are respectively passed through the connecting frame 82 to contact the polyester-cotton fabric placed in the groove 84. The purpose of this step is to accurately position the polyester-cotton fabric to improve its stability during the detection process and ensure the accuracy of the test results. Two high-pressure nozzles 5 and the high-pressure nozzles 7 thereon are used to spray the polyester-cotton fabric placed in the support assembly 8. This step simulates the impact of rain or other liquids on the fabric. By observing whether the lower part of the polyester-cotton fabric is leaking, its waterproof performance can be preliminarily judged. After completing the high-pressure spraying test, the high-pressure nozzle 5 is closed, and the water on the polyester-cotton fabric is sucked dry. The No. 2 cylinder 81 is controlled by an external controller to push the connecting cylinder 81. The connecting frame 82 extends into the water in the supporting frame 1. At this time, the water will not overflow the edge of the concave structure formed by the polyester-cotton fabric, so that it is possible to further observe whether the upper part of the polyester-cotton fabric is water-seeping. This step simulates the waterproof performance of the fabric under long-term immersion. During the high-pressure spraying and immersion test, the detection process can be observed through the transparent protective frame 3 to ensure safety while intuitively understanding the water seepage of the polyester-cotton fabric. When the observation is completed, the connecting frame 82 is retracted by the No. 2 cylinder 81, and the No. 1 cylinder 4 is used to push the humidity detection sensor 6 to perform humidity detection on the polyester-cotton fabric. This step can quantify the humidity change of the fabric and provide more accurate data support for the waterproof performance. The oil-resistant and water-repellent polyester-cotton fabric waterproofness detection device comprehensively evaluates the waterproof performance of the polyester-cotton fabric through precise positioning, high-pressure spraying and immersion tests that simulate actual usage scenarios, and intuitive water seepage observation and humidity detection. This detection device not only improves the accuracy and reliability of the detection, but also improves the safety and efficiency of the detection process.
