Abstract
Description
Technical Field
[0001] This invention relates to the field of roll material testing technology, and specifically to a waterproof roll material testing device. Background Technology
[0002] Waterproof membranes are the core material of waterproofing systems in building roofs, underground projects, transportation tunnels and other fields. Their waterproofing performance under two core service conditions—dynamic rainwater erosion and static water immersion—directly determines the waterproofing safety and structural durability of the project.
[0003] Currently, the industry uses two independent technical systems and equipment for testing the static waterproofing performance and dynamic erosion resistance performance of waterproof membranes. Existing testing equipment can only perform performance tests under single working conditions, and cannot simultaneously or continuously complete the waterproofing performance evaluation of the same pressure test point of the membrane under both dynamic erosion and static immersion conditions.
[0004] During the testing process, the test points may shift when the specimens are transferred between different devices or re-clamped, making it impossible to lock the same weak point for continuous testing. This results in a lack of correlation and comparability between the dual-condition test results. Furthermore, the single-condition independent testing mode is seriously out of sync with the actual service environment of the project, and cannot reproduce the real scenario of the same area of the roll being subjected to alternating scouring and soaking. The test results deviate significantly from the actual performance of the roll in the project, making it difficult to accurately predict its long-term waterproof service life. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes a waterproof membrane testing device to solve the technical problem mentioned in the background art: existing testing devices are unable to simultaneously or continuously complete the waterproof performance evaluation of the membrane under both dynamic scouring and static immersion conditions at the same pressure test point.

After multiple rotations, the transmission mechanism can cause the side stop mechanism to descend and then rise again after a period of time. The reciprocating sliding of the pushing component can drive the transmission mechanism to rotate multiple times. The winding mechanism, the lifting component, and the water tank are periodically activated for water discharge.

[0009] Furthermore, the side-turning assembly includes a fixed rod and a side-turning gear; the fixed rod is fixed to the side pressure plate, and the side-turning gear is rotatably connected to the fixed rod. The sliding of the pushing assembly can drive the side-turning gear to rotate, and the rotation of the side-turning gear can drive the baffle assembly to rotate.
[0010] Furthermore, the baffle assembly includes a baffle telescopic component, a connecting sleeve, a baffle rotating rod, a side baffle, and an elastic rope; the baffle telescopic component is disposed on the side pressure plate and controlled by a tactile switch; after multiple rotations, the transmission mechanism can squeeze and trigger the tactile switch, causing the baffle telescopic component to retract and then rise after intervals; the connecting sleeve is disposed on the telescopic end of the baffle telescopic component, and the baffle rotating rod is rotatably disposed within the connecting sleeve; the rotation of the side rotating gear can drive the baffle rotating rod to rotate; the side baffle is fixed on the baffle rotating rod and connected to the side pressure plate through the elastic rope, and the elastic rope allows the side baffle to abut against the side pressure plate.
[0011] Furthermore, the spray assembly includes a connecting pipe, a spray box, a spray rod, and a transmission belt; the connecting pipe is connected to the flow meter and passes through the side pressure plate; one end of the spray box is rotatably connected to the connecting pipe, and the other end is fixed with the spray rod; the spray rod is rotatably mounted on the side pressure plate; the rotation of the transmission mechanism can drive the spray rod to rotate through the transmission belt.
[0012] Furthermore, the transmission mechanism includes a transmission component, a driven component, and a one-way component; the transmission component, the driven component, and the one-way component are rotatably mounted on the side pressure plate, the reciprocating push of the pushing component can drive the transmission component to reciprocate, the rotation of the transmission component can drive the spray component and the driven component to reciprocate, the reciprocating rotation of the driven component can intermittently drive the one-way component to rotate, and the one-way component can squeeze the tactile switch after multiple rotations.
[0013] Furthermore, the transmission assembly includes a fixed plate, a transmission shaft, a transmission gear, and a transmission bevel gear; the fixed plate is fixedly mounted on the side pressure plate, the transmission shaft is rotatably connected to the fixed plate, and the two ends of the transmission shaft are coaxially fixedly connected to the transmission gear and the transmission bevel gear, respectively. The sliding of the pushing assembly can drive the transmission gear to rotate, and the rotation of the transmission bevel gear can drive the driven assembly to rotate.
[0014] Furthermore, the driven assembly includes a driven shaft, a driven bevel gear, a driven plate, a pawl, and a driven spring. The driven shaft is rotatably connected to the side pressure plate. The driven bevel gear and the driven plate are coaxially fixed on the driven shaft. The driven bevel gear meshes with the transmission bevel gear. The pawl is rotatably and eccentrically mounted on the driven plate and connected to the driven plate through the driven spring.

[0016] The advancements of this application compared to existing technologies are as follows: In this application, the winding mechanism drives the waterproof membrane to move periodically. The lifting component, in coordination with the movement of the winding mechanism, uses the side pressure plate to press the membrane against the frame and tighten it. Then, the valve of the water tank is opened. When the flow meter detects water flow, it activates the pushing component to make it slide back and forth. The back and forth sliding of the pushing component drives the spraying component and the side baffle mechanisms to rotate, realizing the cyclic water spray detection on both sides of the membrane. After the flow meter detects sufficient water spray volume, it stops the pushing mechanism and resets. The spraying mechanism and the side baffle mechanism stop rotating. After being pushed multiple times by the pushing mechanism, the transmission mechanism causes the side baffle mechanism to descend and press against the membrane. As the water tank continues to drain, a sealed water pressure is formed above the membrane, thereby realizing the hydrostatic pressure detection. After a period of time, the water tank stops draining, the side baffle mechanism resets and rises, the lifting component retracts, and the winding mechanism starts again, and the cycle repeats.
[0017] In existing technologies, spray testing and hydrostatic pressure testing of waterproof membranes often employ a multi-instrument parallel zoned testing approach. This involves setting up separate spray and hydrostatic pressure structures to perform different tests on different locations of the waterproof membrane. This approach makes it difficult to simultaneously assess the waterproof performance of the same pressure point under both dynamic rainwater erosion and static water immersion conditions. It also makes it difficult to accurately locate weak points in the membrane under pressure, leading to missed detections. This application addresses this issue by adding a closed-loop water filling test to the same pressure area after the spray test, forming a two-step progressive testing process of "spray first, then fill with water." This approach can differentiate the failure conditions of weak points in the membrane, reduce the missed detection rate, and provide test results that better reflect actual engineering scenarios.
[0018] In addition, the spraying test in this application is conducted by reciprocating the rotation of the spraying mechanism, which further simulates the actual rainwater falling situation and makes the test data closer to reality. Attached Figure Description

Detailed Implementation
[0022] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0023] Please refer to the following: Figures 1-5 This embodiment provides a waterproof membrane testing device, including a winding mechanism 10, a frame 1, a lifting component 2, a side pressure plate 3, a water tank 4, a flow meter 5, a spray assembly 6, a side baffle mechanism 7, a pushing assembly 8, and a transmission mechanism 9; The lifting component 2 is mounted on the frame 1, and the telescopic end of the lifting component 2 is provided with a side pressure plate 3; It should be understood that the winding mechanism 10 is located on both sides of the frame 1. The roll material is sleeved on one end of the winding mechanism 10, and the free end of the roll material passes through the frame 1 and is connected to the other end of the winding mechanism 10. The activation of the winding mechanism 10 enables the roll material to be wound from one side to the other side. The lifting component 2 can extend to allow the side pressure plate 3 to press the roll material onto the frame 1. The frame 1 is equipped with a humidity detection mechanism at the corresponding position of the side pressure plate 3, which detects water seepage from the roll material. Specifically, the side pressure plate 3 is a U-shaped plate. After the side pressure plate 3 is lowered, it can tighten and press the roll material above the frame 1 against the frame 1. The lifting component 2 is an electric telescopic rod or cylinder, etc., that can extend and retract.
[0024] Water tank 4 is mounted on frame 1, flow meter 5 is mounted on side pressure plate 3, one end of flow meter 5 is connected to water tank 4 via hose, and the other end is connected to spray assembly 6, spray assembly 6 is rotatably mounted on side pressure plate 3; it should be understood that water tank 4 controls water output time via valve, and hose is preferably a retractable corrugated pipe.
[0025] The side baffle mechanism 7 is rotatably and liftably mounted on both sides of the side pressure plate 3. The push assembly 8 is slidably mounted on the side pressure plate 3 and can drive each side baffle mechanism 7 and the spray assembly 6 to rotate. The flow meter 5 can control the start and stop of the push assembly 8. Specifically, the flow meter 5 can accumulate readings. When the flow meter 5 detects water flowing through it, the control circuit activates the push component 8 to make the push component 8 slide back and forth. After detecting X amount of water, the control circuit stops and resets the push component 8. After accumulating Y amount of water based on X, the flow meter 5 returns to zero. Among them, X amount of water is used to simulate the spray waterproof test of rainwater erosion, and Y amount of water is used to simulate the hydrostatic pressure test of long-term water accumulation.
[0026] The transmission mechanism 9 is rotatably mounted on the side pressure plate 3. After multiple rotations, the transmission mechanism 9 can cause the side stop mechanism 7 to descend and then rise again after a period of time. The reciprocating sliding of the pushing component 8 can drive the transmission mechanism 9 to rotate multiple times. Specifically, after the two baffle mechanisms descend, they form a tubular structure that seals the roll material with the side pressure plate 3. When the sliding component 8 stops, it triggers the descent switch of the side baffle mechanism 7, causing the side baffle mechanism 7 to descend. After maintaining the descending state for a period of time, it automatically rises again. The time it maintains the descending state is not less than the time it takes for the water tank 4 to release Y units of water. The specific values of X and Y can be set as needed.
[0027] The winding mechanism 10, the lifting component 2, and the water tank 4 are periodically activated for water discharge.
[0028] Specifically, the valves of the winding mechanism 10, the lifting component 2, and the water tank 4 are controlled by a control circuit. There is a time difference between the opening and closing of the winding mechanism 10, the opening and closing of the lifting component 2 (i.e., extension and retraction), and the opening and closing of the water tank 4 valve. There is also a time difference between opening and reopening. When the winding mechanism 10 stops winding, the lifting component 2 extends and the water tank 4 valve opens to release water. When the winding mechanism 10 starts winding, the lifting component 2 retracts and the water tank 4 valve closes.
[0029] In other embodiments, the pushing assembly 8 includes a pushing member 81, a pushing slider 82, and a pushing rack 83; the pushing member 81 is telescopically mounted on the side pressure plate 3 and connected to the pushing slider 82, and the flow meter 5 can control the start and stop of the pushing member 81; the pushing slider 82 is slidably mounted on the side pressure plate 3 and connected to the pushing rack 83; the reciprocating sliding of the pushing rack 83 can drive the spray assembly 6, the transmission mechanism 9, and the two side baffle mechanisms 7 to rotate respectively.
[0030] Specifically, the pusher 81 is an electric telescopic rod, and its movable end is connected to the push slider 82 through a connecting plate. The movable end has three states: closest, middle, and farthest from the fixed end. In the initial state, the movable end is in the middle position. After the pusher 81 is started, its movable end switches back and forth between the three states, and after stopping, the movable end returns to the middle position. When the pusher 81 moves to one side, it drives the side baffle mechanism 7 on that side to rotate, and the spray assembly 6 rotates to that side together. When the pusher 81 moves to the other side, the side baffle mechanism 7 that rotated first resets, and the spray assembly 6 and the baffle mechanism on the other side rotate.
[0031] In other embodiments, the side-blocking mechanism 7 includes a baffle assembly 71 and a side-rotating assembly 72. The baffle assembly 71 is vertically and vertically mounted on the side pressure plate 3 and can rotate. The transmission mechanism 9 can lower the baffle assembly 71 after multiple rotations and automatically raise it after intervals. The side-rotating assembly 72 is rotatably mounted on the side pressure plate 3, and the movement of the pushing assembly 8 can drive the baffle assembly 71 to rotate through the side-rotating assembly 72. It should be understood that the side-blocking mechanism 7 has two sets of components, respectively located on the openings on both sides of the side pressure plate 3. The rotation of the pushing rack 83 drives the side-rotating assembly 72 to rotate, and the rotation of the side-rotating assembly 72 drives the baffle assembly 71 to rotate.
[0032] In other embodiments, the side-turning assembly 72 includes a fixed rod 721 and a side-turning gear 722. The fixed rod 721 is fixed to the side pressure plate 3, and the side-turning gear 722 is rotatably connected to the fixed rod 721. The sliding of the pushing assembly 8 can drive the side-turning gear 722 to rotate, and the rotation of the side-turning gear 722 can drive the baffle assembly 71 to rotate. Specifically, the side-turning gear 722 meshes with the pushing rack 83, and the side-turning gear 722 and the baffle assembly 71 are splined and always maintain the splined connection. When the baffle assembly 71 is not descending, it maintains the splined connection with the side-turning gear 722. At this time, the rotation of the side-turning gear 722 drives the baffle assembly 71 to rotate. The descent of the baffle assembly 71 does not drive the side-turning gear 722 to rotate.
[0033] In other embodiments, the baffle assembly 71 includes a baffle telescopic member 711, a connecting sleeve 712, a baffle rotating rod 713, a side baffle 714, and an elastic rope 715. The baffle telescopic member 711 is mounted on the side pressure plate 3 and is controlled by a tactile switch 73. After multiple rotations, the transmission mechanism 9 can squeeze and trigger the tactile switch 73, causing the baffle telescopic member 711 to retract and then rise after intervals. The connecting sleeve 712 is mounted on the telescopic end of the baffle telescopic member 711. The baffle rotating rod 713 is rotatably fitted inside the connecting sleeve 712. The rotation of the side rotating gear 722 can drive the baffle rotating rod 713 to rotate. The side baffle 714 is fixed on the baffle rotating rod 713 and is connected to the side pressure plate 3 via the elastic rope 715. The elastic rope 715 allows the side baffle 714 to abut against the side pressure plate 3.
[0034] Specifically, the baffle rod 713 and the side gear 722 are connected by a spline, allowing the baffle rod 713 to both rise and fall and rotate on its own axis driven by the side gear 722; the baffle telescopic component 711 is an electric telescopic rod with a delayed reset, the delay time being the time when the spray detection and hydrostatic pressure detection are completed. It should be understood that the elastic rope 715 can resist the outward pressure on the side baffle 714 during water injection, ensuring that the side baffle 714 always abuts against the openings on both sides of the side pressure plate 3.
[0035] In other embodiments, the spray assembly 6 includes a connecting pipe 61, a spray box 62, a spray rod 63, and a transmission belt 64. The connecting pipe 61 is connected to the flow meter 5 and passes through the side pressure plate 3. One end of the spray box 62 is rotatably connected to the connecting pipe 61, and the other end is fixedly equipped with the spray rod 63. The spray rod 63 is rotatably mounted on the side pressure plate 3. The rotation of the transmission mechanism 9 can drive the spray rod 63 to rotate through the transmission belt 64. Specifically, the transmission belt 64 is tightly fitted onto the spray rod 63 and the transmission mechanism 9 to form a transmission fit. The spray box 62 is provided with several spray holes facing the roll material.
[0036] In other embodiments, the transmission mechanism 9 includes a transmission component 91, a driven component 92, and a one-way component 93. The transmission component 91, driven component 92, and one-way component 93 are rotatably mounted on the side pressure plate 3. The reciprocating motion of the pushing component 8 drives the transmission component 91 to reciprocate, and the rotation of the transmission component 91 drives the spraying component 6 and the driven component 92 to reciprocate. The reciprocating rotation of the driven component 92 intermittently drives the one-way component 93 to rotate, and after multiple rotations, the one-way component 93 presses the tactile switch 73. Specifically, the reciprocating sliding motion of the pushing rack 83 drives the transmission component 91 and the driven component 92 to reciprocate. The intermittent movement of the driven component 92 extends the spraying time, reducing the possibility of insufficient spraying time affecting the detection results.
[0037] In other embodiments, the transmission assembly 91 includes a fixed plate 911, a transmission shaft 912, a transmission gear 913, and a transmission bevel gear 914. The fixed plate 911 is fixed to the side pressure plate 3, and the transmission shaft 912 is rotatably connected to the fixed plate 911. The two ends of the transmission shaft 912 are coaxially fixedly connected to the transmission gear 913 and the transmission bevel gear 914, respectively. The sliding of the pushing assembly 8 can drive the transmission gear 913 to rotate, and the rotation of the transmission bevel gear 914 can drive the driven assembly 92 to rotate. Specifically, the transmission gear 913 meshes with the pushing rack 83, and the transmission belt 64 tightly wraps around the transmission shaft 912 and the water spray rod 63.
[0038] In other embodiments, the driven assembly 92 includes a driven shaft 921, a driven bevel gear 922, a driven plate 923, a pawl 924, and a driven spring 925. The driven shaft 921 is rotatably connected to the side pressure plate 3. The driven bevel gear 922 and the driven plate 923 are coaxially fixed on the driven shaft 921. The driven bevel gear 922 meshes with the transmission bevel gear 914. The pawl 924 is rotatably and eccentrically mounted on the driven plate 923 and is connected to the driven plate 923 through the driven spring 925. The pawl 924 can drive the unidirectional assembly 93 to rotate unidirectionally with the reciprocating rotation of the driven plate 923.
[0039] In other embodiments, the one-way component 93 includes a one-way rotating shaft 931, a ratchet 932, and a pressing plate 933. The one-way rotating shaft 931 is rotatably connected to the side pressing plate 3, the ratchet 932 is coaxially fixed to the one-way rotating shaft 931, and the pawl 924 can drive the ratchet 932 to rotate in one direction. The pressing plate 933 is fixed to the one-way rotating shaft 931 and can press the tactile switch 73. It should be understood that the friction between the one-way rotating shaft 931 and the side pressing plate 3 can fix the one-way rotating shaft 931 in its position before being pushed by the pawl 924. Preferably, the one-way rotating shaft 931 and the side pressing plate 3 adopt an interference fit of 0.05mm-0.2mm.
[0040] The above-mentioned waterproof membrane testing device is used as follows: In the initial state, the lifting component 2 is in the retracted state, the movable end of the pushing component 81 is in the middle state, the two side baffles 714 are flat against the two sides of the side pressure plate 3 under the drive of the elastic rope 715, and the winding mechanism 10 stops when it is in the middle state of winding. During testing, the winding mechanism 10 continuously winds the material for a period of time and then stops winding. The lifting component 2 extends the side pressure plate 3 to press the roll material against and tightly press it onto the testing table of the frame 1. Then the valve of the water tank 4 is opened. After the flow meter 5 detects the water flow, it starts the push component 81. The push component 81 slides back and forth, driving the spray assembly 6 to rotate and the two side baffles 714 to rotate in sequence. After the flow meter 5 detects X amount of water, the control circuit stops the pusher 81, which then resets to the intermediate state. At this time, the pusher rack 83 does not mesh with the two side rotating gears 722. Meanwhile, after the one-way rotating shaft 931 rotates multiple times, the extrusion plate 933 presses through the touch switch 73, and the two baffle telescopic members 711 retract, causing the two side baffles 714 to descend and abut against the roll material. Under the action of the elastic rope 715, they remain in close contact with the two side openings of the side pressure plate 3, forming a closed cavity above the roll material. Water continuously flows from the water tank 4 and accumulates in this closed cavity until the flow meter 5 detects Y amount of water after accumulating X amount of water. Then the flow meter 5's measurement returns to zero. Subsequently, the lifting member 2 is raised, and the winding mechanism 10 winds up again, repeating the cycle.
[0041] The aforementioned waterproof membrane testing device can be upgraded to a closed water filling test after the spray test is completed, forming a two-step progressive test of "spraying first, then filling with water".
[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
