Description

Technical Field

[0001] The present invention relates to the technical field of waterproof detection of tent fabrics, and in particular to a waterproof detection device for fabrics used in outdoor tents. Background Art

[0002] Outdoor tent fabrics are specialized textile materials designed for outdoor activities such as camping and mountaineering. Their core performance requirements include lightweight, abrasion resistance, tear resistance, and excellent water resistance. The waterproofness of tent fabrics is directly related to user comfort and safety. Inadequate waterproofing can lead to internal water seepage, especially in rainy or humid environments, affecting user experience and even posing a safety hazard. Currently, mainstream tent fabrics are mostly based on polyester or nylon, coated with waterproof coatings such as polyurethane (PU) or polytetrafluoroethylene (PTFE), or laminated with a waterproof membrane. The waterproof performance of these materials must be verified using professional testing equipment to ensure they meet design standards in actual use.

[0003] However, existing waterproof testing devices have significant shortcomings. Conventional equipment can usually only perform single-sided waterproof testing on fabrics, that is, it can only simulate water pressure or water drop impact in a single direction, and cannot fully reflect the double-sided water immersion that the fabric may encounter in actual use. For example, the top of a tent needs to withstand external rain, while the interior may cause reverse infiltration due to the accumulation of condensation water, but existing devices make it difficult to switch between single-sided and double-sided testing modes in the same test. In addition, the traditional testing process relies on manual operations, such as manually flipping the fabric or adjusting the test components, resulting in low efficiency and the test results are easily interfered with by human factors.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1-8 , Embodiment 1, a waterproof detection device for fabrics for outdoor tents, comprising a detection platform 1, a support plate 2 is welded to the inner wall of one side of the detection platform 1, and the outer wall of the top of the support plate 2 is fixedly connected to a cylinder 3 by screws, the piston rod of the cylinder 3 is fixedly connected to a mounting plate 4, and the mounting plate 4 is fixedly connected to a servo motor 5 by screws, the output shaft of the servo motor 5 is fixedly connected to a plate seat 6, and the top and bottom of the inner wall of the plate seat 6 are both slidably connected to positioning plates 7, spheres 8 are provided at the centers of the outer walls on both sides of the positioning plate 7, and a telescopic spring 9 is fixedly connected between the positioning plate 7 and the plate seat 6, a waterproof test assembly 10 is screwed on the inner wall of the positioning plate 7 away from the plate seat 6, a fixing tube 11 is fixedly connected to the inner wall of the other side of the detection platform 1, and a passive flip assembly 12 is rotatably connected to the inner wall of the fixing tube 11, and a traction assembly 13 is provided on the outer wall of the passive flip assembly 12.

[0030] Cylinder 3, via its piston rod, drives mounting plate 4 horizontally. Mounting plate 4 is rigidly connected to servo motor 5, whose output shaft rotates plate base 6. Positioning plates 7 at the top and bottom of plate base 6 are elastically retracted and retracted by telescopic springs 9. Balls 8 on either side of these plates flexibly engage with the traction frame 133 of traction assembly 13, ensuring uniform force during fabric clamping. A waterproof test assembly 10 mounted on positioning plate 7 applies water pressure via a water reservoir 101. A passive flip assembly 12 is housed within a fixed tube 11 on the other side of test platform 1. Its fabric placement ring 123 is used to hold the fabric to be tested.

[0031] This embodiment enables flexible switching between single- and double-sided testing, improving comprehensive testing. It also features automated operation and precise control, reducing human error. Furthermore, the passive flip assembly 12 automatically resets the fabric using a torsion spring 122. Furthermore, the traction assembly 13, in conjunction with the sphere 8, controls the flexible grip of the water storage cylinder 101, adapting to fabrics of varying thicknesses and materials. This expands the device's applicability and reduces maintenance costs.

[0032] In the second embodiment, the waterproof test assembly 10 includes a water storage cylinder 101, a sealing cover 102, a water baffle 103, a water permeable pipe 104, a solenoid valve 105 and a water drop sensor 106, wherein the water storage cylinder 101 includes two, and the two water storage cylinders 101 are symmetrically distributed up and down, the water storage cylinder 101 is screwed on the inner wall of the positioning plate 7, the sealing cover 102 is screwed on the outer wall of the water storage cylinder 101, and the water baffle 103 is fixedly connected to the inner wall of the water storage cylinder 101. On the wall, the permeable pipe 104 is installed on the inner wall of the water baffle 103, the solenoid valve 105 is installed on the outer wall of the permeable pipe 104, and the solenoid valve 105 is located at the bottom of the water baffle 103, and the water drop sensor 106 is installed on the bottom inner wall of the water baffle 103. The waterproof test assembly 10 also includes a limiting ring 107, wherein the limiting ring 107 is arranged on the outer wall of the water storage cylinder 101, and the limiting ring 107 is tightly attached to the outer wall of the positioning plate 7.

[0033] The core of the waterproof testing assembly 10 is a symmetrically arranged water storage cylinder 101, separated by a baffle 103 into a water storage area and a testing area. A permeable pipe 104 runs through the baffle 103. A solenoid valve 105 controls the water flow, and a water drop sensor 106 monitors the amount of water seeping through in real time. For top-side testing, the solenoid valve 105 in the upper water storage cylinder 101 opens, allowing water to flow through the permeable pipe 104 and impact the fabric surface. For bottom testing, the water flows to the lower water storage cylinder 101. A retaining ring 107 ensures secure positioning between the water storage cylinder 101 and the positioning plate 7, preventing loosening. The removable sealing cap 102 facilitates cleaning and maintenance. The symmetrical layout of the two water storage cylinders 101 enables the device to quickly switch between single- and double-sided testing modes. After the servo motor 5 drives the plate base 6 to rotate 180°, the upper and lower water storage cylinders 101 swap positions, simulating a double-sided immersion scenario.

[0034] In this embodiment, the symmetrically arranged water storage cylinders 101 and the fabric placement ring 123 are linked to each other to apply water pressure to the top and bottom of the fabric. For single-sided testing, only the solenoid valve 105 of the single water storage cylinder 101 needs to be activated. For double-sided testing, the servo motor 5 flips and swaps the positions of the two water storage cylinders 101, simulating a double-sided immersion of the fabric. This solves the problem of conventional devices' inability to flexibly switch test modes, effectively improving the test coverage and accuracy of the fabric. The linked design of the two water storage cylinders 101 enables single-sided or double-sided water pressure loading through independent control of the solenoid valves 105. The highly sensitive detection of the water droplet sensor 106 ensures that even small leaks are recorded. The automatic reset function of the passive flip assembly 12 reduces manual intervention, and the flexible clamping of the traction assembly 13 prevents fabric damage. The entire device, through the combination of precision mechanical structure and automated control system, significantly improves testing efficiency and reliability.

[0035] Embodiment 3, the passive flip component 12 includes a rotating column 121, a torsion spring 122 and a cloth placement ring 123, wherein the rotating column 121 is rotatably connected to the inner wall of the fixed tube 11, the torsion spring 122 is located outside the rotating column 121 and the fixed tube 11, and the torsion spring 122 is fixedly connected between the rotating column 121 and the fixed tube 11, and the cloth placement ring 123 for placing outdoor tent cloth is welded to the outer wall of one end of the rotating column 121, and the traction component 13 includes a circular plate 131, a T-shaped plate 132 and a traction frame 133, wherein the circular plate 131 is welded to the outer wall of the rotating column 121, and the T-shaped plate 132 is welded to the outer walls on both sides of the circular plate 131, the traction frame 133 includes two groups, and each group of traction frames 133 includes two, and the two traction frames 133 of each group are respectively welded to the outer walls at both ends of the T-shaped plate 132.

[0036] The passive flip assembly 12 adjusts the fabric position through the rotational connection between the rotating column 121 and the fixed tube 11. After the test, the torsion spring 122 automatically resets the rotating column 121, returning the fabric placement ring 123 to its initial position. The circular plate 131 of the traction assembly 13 forms a rigid connection with the T-shaped plate 132. The traction frame 133 limits the movement of the positioning plate 7 and assists the two water storage cylinders 101 in clamping the fabric edges and securing them. When the servo motor 5 drives the plate holder 6 to rotate, the positions of the two water storage cylinders 101 can be interchanged.

[0037] The two water storage cylinders 101 are respectively located at the top and bottom of the fabric placement circle 123. The water storage cylinder 101 with the opening facing upward is located at the bottom of the fabric placement circle 123, and the water storage cylinder 101 with the opening facing downward is located at the top of the fabric placement circle 123. The outer diameter of the fabric placement circle 123 is adapted to the outer diameter of the water storage cylinder 101.

[0038] A symmetrically distributed first guide rod 14 is fixedly connected to the inner wall of the plate seat 6 away from the telescopic spring 9, and a first linear bearing is fixedly connected to the inner wall of the end of the positioning plate 7 away from the water storage cylinder 101, and the first guide rod 14 is slidably connected to the inner wall of the first linear bearing. A second linear bearing is installed on the inner wall of one side of the support plate 2, and a second guide rod 15 is slidably connected to the inner wall of the second linear bearing, and the outer wall of one end of the second guide rod 15 is fixedly connected to the outer wall of the mounting plate 4.

[0039] The first guide rod 14 and the second guide rod 15 respectively constrain the movement tracks of the positioning plate 7 and the mounting plate 4 through the first linear bearing and the second linear bearing to ensure the movement accuracy.

[0040] The top outer wall of the detection platform 1 is fixedly connected to a PLC controller 16 by screws, and the PLC controller 16 is connected to the cylinder 3, the servo motor 5, the solenoid valve 105 and the water drop sensor 106 by signal lines.

[0041] The PLC controller 16 integrates control of the cylinder 3, servo motor 5, and solenoid valve 105, automating the entire process of fabric clamping, flipping, water injection, and testing. For example, the servo motor 5 rotates the plate holder 6 to adjust the test angle, while the water droplet sensor 106 monitors the penetration status in real time and provides feedback. For example, the water pressure application time can be extended or the test surface can be switched to comprehensively assess the fabric's waterproof performance. Compared to equipment that relies on manual operation, this device reduces human intervention and improves testing efficiency and consistency.

[0042] Working principle:

[0043] After the device is started, both water cylinders 101 are pre-filled with water, and the upper water cylinder 101 is sealed with water through the sealing cover 102, and water is directly poured into the lower water cylinder 101. During the test, the cloth is cut into a circular shape and placed on the cloth placement ring 123;

[0044] The PLC controller 16 then controls the cylinder 3 to drive the mounting plate 4 to translate, so that the water storage cylinder 101 approaches the fabric placement circle 123. With the cooperation of the traction frame 133 and the sphere 8, the two positioning plates 7 continue to move closer until the two water storage cylinders 101 are close to and fixed on the fabric to be tested on the fabric placement circle 123.

[0045] The servo motor 5 adjusts the rotation angle of the plate base 6, depending on the test mode, to align the opening of the corresponding water reservoir 101 with the test surface of the fabric. If a single-sided test is required, the PLC controller 16 opens the solenoid valve 105 of the designated water reservoir 101. Water from the upper layer flows through the permeable pipe 104 and is evenly applied to the fabric surface. The water droplet sensor 106 in the lower layer monitors the water seepage in the lower water reservoir 101 in real time and provides feedback. If a double-sided test is required, the servo motor 5 drives the plate base 6 to rotate 180°, swapping the positions of the upper and lower water reservoirs 101. The solenoid valve 105 of the upper water reservoir 101 is opened, and the test is repeated to simulate a double-sided immersion environment.

[0046] During the test, the traction frame 133 of the traction assembly 13, through the flexible connection of the sphere 8, adaptively adjusts the fabric tension to prevent excessive stretching. After the test is completed, the cylinder 3 resets and raises the waterproof test assembly 10. The torsion spring 122 of the passive flip assembly 12 automatically rotates and resets the fabric placement ring 123. The PLC controller 16 summarizes the sensor data and generates a test report.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
