[0043] The water tank 4 is fixedly arranged on the support plate 3, and the water adding airbag 5 is arranged in the water tank 4.

A water adding pipe 8 is provided through the bottom wall of the water tank 4 and the support plate 3. A bell mouth 9 is provided at the bottom end of the water adding pipe 8. The water adding pipe 8 is used to spray out the water in the water outlet tank or to suck back the sprayed water. Specifically, when the pressure in the water tank 4 increases, the water in the water tank 4 is sprayed out through the water adding pipe 8. When the pressure in the water tank 4 decreases, the water is sucked back into the water tank 4.

[0044] A guide cylinder 10 and a reset mechanism 11 are fixedly provided on the lower surface of the support plate 3. The guide cylinder 10 is driven by the support plate 3 to rise and fall and slide in the detection cylinder 1. When the guide cylinder 10 is driven by the support plate 3 to move downward, the waterproof coiled material is pressed into the detection cylinder 1. The pressure plate 7 is connected to the reset mechanism 11. The pressurized airbag 6 is arranged between the pressure plate 7 and the support plate 3. The pressure plate 7 is driven by the pressurized airbag 6 to rise and fall and slide in the guide cylinder 10.

The airflow channel switching mechanism 13 is connected to the water-adding air bag 5 and the pressurizing air bag 6 through bronchus 1 15 and bronchus 2 16 respectively. When in specific use, the airflow channel switching mechanism 13 is controlled to connect the dual-purpose air pump 12 to the water-adding air bag 5, so that the water-adding air bag 5 can be pumped or inflated, thereby controlling the internal pressure of the water tank 4. The airflow channel switching mechanism 13 is used to connect the dual-purpose air pump 12 to the pressurizing air bag 6, so that the pressurizing air bag 6 can be pumped or inflated, thereby controlling the lifting position of the pressurizing plate 7 in the guide tube 10.

[0048] Specifically, see Figure 3 In this embodiment, a water inlet 17 is provided on the water storage tank 4, and a sealing plug 18 is stuck in the water inlet 17. Through the setting of the water inlet 17, a small amount of water can be regularly added to the water storage tank 4.

When the sealing airbag 19 is inflated, the sealing airbag 19 can seal the gap between the guide cylinder 10 and the detection cylinder 1, thereby ensuring the smooth progress of the pressurized detection.

[0050] Specifically, see Figure 2 , Figure 3 , Figure 4 and Figure 6 In this embodiment, the air flow channel switching mechanism 13 includes a support 21, a switching shell 22, a switching motor 23 and a switching adjustment plate 24. The switching shell 22 is fixedly arranged on the support 21. The switching shell 22 includes an upper pumping and charging chamber 25 and a lower switching chamber 26. The diameter of the upper pumping and charging chamber 25 is smaller than the diameter of the lower switching chamber 26. A group of main air holes 27 are arranged on the top wall of the upper pumping and charging chamber 25. The main air holes 27 are connected to the main air pipe 14. Three groups of bronchial holes 28 are arranged on the side wall of the lower switching chamber 26. The three groups of bronchial holes 28 are respectively connected to bronchus one 15, bronchus two 16 and bronchus three 29. The switching motor 23 is fixedly arranged on the outer wall of the switching shell 22, and the switching motor 23 is arranged corresponding to the lower switching cavity 26. The switching adjustment plate 24 is fixedly connected to the output shaft of the switching motor 23. The switching adjustment plate 24 is rotatably arranged in the lower switching cavity 26. The switching adjustment plate 24 is a non-360° arc-shaped plate. The switching adjustment plate 24 is driven by the switching motor 23 to block and block two groups of branch holes 28 at the same time. The thickness of the switching adjustment plate 24 is less than the thickness of the switching shell 22. By setting the thickness difference, the main air hole 27 can always be kept in communication with a group of branch holes 28 that are not blocked or blocked.

[0051] During specific use, the switching motor 23 is used to drive the switching adjustment plate 24 to rotate, and the blocking position of the three groups of air holes 28 by the switching adjustment plate 24 is adjusted, so that the connection state between the dual-purpose air pump 12 and the water-adding air bag 5, the pressurizing air bag 6 and the sealing air bag 19 can be adjusted, thereby meeting the water adding, pressurizing and sealing requirements during detection.

[0052] Specifically, in this embodiment, the lower parts of bronchus 1 15, bronchus 2 16 and bronchus 3 29 are all flexible telescopic tubes, so that they can adapt to the lifting and lowering of the support plate 3 and undergo corresponding deformations, and the vertical parts of branch 1 36 and branch 2 37 are flexible telescopic tubes, so that they can adapt to the lifting and lowering of the pressure plate 7 and undergo corresponding deformations.

[0053] Specifically, see Figure 3 and Figure 5 In this embodiment, the reset mechanism 11 includes a reset sleeve 30, a reset slide bar 31 and a reset spring 32.

When the pressurized airbag 6 is deflated and contracted, the reset mechanism 11 can drive the pressure plate 7 to slide along the guide cylinder 10, thereby driving the pressure plate 7 to move up along the guide cylinder 10; a plurality of reset mechanisms 11 are provided between the support plate 3 and the pressure plate 7, and the setting of a plurality of reset mechanisms 11 can improve the stability of the reset force of the pressure plate 7.

[0054] Specifically, see Figure 3 In this embodiment, the detection tube 1 is a transparent tube, so as to observe whether there is water leakage in the detection tube 1. A supporting plate 33 is provided on the upper end of the detection tube 1 along the circumferential direction. The supporting plate 33 is used to support the edge of the waterproof coiled material to be detected. A placement ring plate 34 is provided on the inner wall of the detection tube 1. The placement ring plate 34 is used to place the waterproof coiled material to be detected pressed by the guide tube 10. When the guide tube 10 moves downward, the waterproof coiled material is pushed into the detection tube 1. The placement ring plate 34 and the guide tube 10 cooperate to clamp and fix the waterproof coiled material to be detected. In addition, the edge of the waterproof membrane is clamped and fixed by the cooperation of the support plate 3 and the supporting plate 33. A return pipe 35 is connected between the lower part of the detection tube 1 and the water storage tank 4. When the waterproofness of the waterproof membrane does not meet the requirements, the test water will enter the detection tube 1 through the waterproof membrane. The test water in the detection tube 1 can be pumped back into the water storage tank 4 through the setting of the return pipe 35; the edges connected to the supporting plate 33 and the placement ring plate 34 and the side wall of the detection tube 1 are all arc structures, which can prevent the waterproof membrane from being damaged by the right-angle connection edges.

[0055] Specifically, see Figure 7 In this embodiment, the portion of the water adding pipe 8 located between the support plate 3 and the pressure plate 7 includes a branch 1 36 and a branch 2 37. The branch 1 36 and the branch 2 37 are distributed in a rectangular structure. The branch 1 36, the branch 2 37 and the return pipe 35 are all provided with a one-way pressure control mechanism 38, and the one-way pressure control mechanisms 38 arranged on the branch 1 36 and the branch 2 37 are in opposite directions. When the water adding airbag 5 expands, the water in the water storage tank 4 is added to the waterproof coiled material fixed in the detection tube 1 through the bell mouth 9 through the branch 1 36. When the water adding airbag 5 contracts, the water in the waterproof coiled material or the detection tube 1 flows back to the water storage tank 4 through the branch 2 37 and the return pipe 35, respectively, to realize automatic reuse of water.

[0056] Specifically, see Figure 7 and Figure 8In this embodiment, the one-way pressure control mechanism 38 includes a control cylinder 39, a pressure sealing plate 40 and a pressure sealing assembly. The two ends of the control cylinder 39 are respectively provided with a water inlet 41 and a water outlet 42.

The pressure sealing plate 40 is slidably arranged in the control cylinder 39, and the pressure sealing plate 40 moves relative to the water inlet 41. A plurality of pressure sealing assemblies are provided between the control cylinder 39 and the pressure sealing plate 40. When reverse pressure is applied, the pressure sealing assembly does not operate, and the pressure sealing plate 40 seals the water inlet 41. When positive pressure is applied, the pressure sealing assembly is deformed, and the pressure sealing plate 40 releases the seal on the water inlet 41.

[0057] Specifically, see Figure 8 In this embodiment, the pressure sealing assembly includes a sealing sleeve 43, a sealing slide rod 44 and a sealing spring 45. The sealing sleeve 43 is fixed on the inner wall of the control cylinder 39, the sealing slide rod 44 is slidably arranged in the sealing sleeve 43, and the sealing spring 45 is sleeved on the sealing sleeve 43 and the sealing slide rod 44. The two ends of the sealing spring 45 are respectively connected to the control cylinder 39 and the pressure sealing plate 40. When there is no pressure or reverse pressure is applied, the sealing spring 45 drives the pressure sealing plate 40 to seal the water inlet 41. When positive pressure is applied, the sealing spring 45 is compressed and the pressure sealing plate 40 is moved away from the water inlet 41.

[0058] Specifically, see Figure 1 , Figure 2 and Figure 3 In this embodiment, as another embodiment of the present scheme, compared with the above-mentioned embodiment, this embodiment provides a waterproof membrane performance testing device: it also includes a support frame 46, the support 21 is fixedly arranged on the support frame 46, the support frame 46 is provided with an electric lifting cylinder 47, the support plate 3 is fixedly connected to the free end of the electric lifting cylinder 47, and the support plate 3 and the guide cylinder 10 are driven to rise and fall relative to the detection cylinder 1 under the action of the electric lifting cylinder 47. When the guide cylinder 10 is driven into the detection cylinder 1, the waterproof membrane placed in the detection cylinder 1 can be watered and pressurized respectively through the expansion of the inflated volume of the water-adding airbag 5 and the pressurizing airbag 6.

[0059] The working principle of the waterproofing coiled material performance testing device provided in this embodiment is as follows:

[0060] (1) Place the cut sheet waterproofing membrane on the supporting plate 33 of the detection tube 1, start the electric lifting cylinder 47 to extend and drive the supporting plate 3 to move downward, and the supporting plate 3 drives the guide tube 10 to move downward. When the guide tube 10 moves downward, the waterproofing membrane is pressed into the detection tube 1 and supported by the placement ring plate 34;

[0061] (2) Under the action of the switching motor 23, the switching adjustment plate 24 is driven to rotate, and the switching adjustment plate 24 rotates to block the bronchial holes 28 corresponding to the branch pipes 1 and 2. At this time, the main air pipe 14 is connected with the bronchial holes 28 corresponding to the branch pipe 3 through the upper pumping and inflating chamber 25 and the lower switching chamber 26; the pumping and inflating dual-purpose air pump 12 is inflated, and the sealing airbag 19 is expanded under the conveying action of the branch pipe 3 and the ventilation chamber 20, and the sealing airbag 19 seals the gap between the guide tube 10 and the detection tube 1;

[0062] (3) Then, under the action of the switching motor 23, the switching adjustment plate 24 is driven to rotate to block the branch holes 28 corresponding to the branch pipes 2 and 3. At this time, the main air pipe 14 is connected with the branch holes 28 corresponding to the branch pipe 1 through the upper pumping and charging chamber 25 and the lower switching chamber 26; the pumping and charging dual-purpose air pump 12 is inflated, and the water-adding airbag 5 is expanded under the conveying action of the branch pipe 1. The expanded water-adding airbag 5 applies positive pressure to the water storage tank 4, and the pressure in the water storage tank 4 is pressed out from the water-adding pipe 8 and sprayed onto the waterproof membrane through the bell mouth 9, thereby realizing the water-adding action;

[0063] During this process, the water on the upper part of the water supply pipe 8 is pushed to the one-way pressure control mechanism 38 of the branch 1 36, the branch 2 37 and the return pipe 35 under pressure, wherein the pressure sealing plate 40 of the branch 2 37 and the return pipe 35 is subjected to reverse pushing pressure, and the pressure sealing plate 40 is tightly fitted at the water inlet 41 under the pushing pressure of the water flow, and the water inlet 41 is pressure-sealed, while the pressure sealing plate 40 on the branch 1 36 is subjected to positive pressure, and the water flow pushes the pressure sealing plate 40 from the water inlet 41, the sealing spring 45 is compressed, and the sealing slide rod 44 slides into the sealing sleeve 43, and the pressure sealing plate 40 is moved away from the water inlet 41 of the branch 1 36, and the detection water is sprayed out through the branch 1 36 and the bell mouth 9;

[0064] (4) Finally, under the action of the switching motor 23, the switching adjustment plate 24 is driven to rotate to block the bronchial holes 28 corresponding to the branch pipes 1 and 3. At this time, the main air pipe 14 is connected to the bronchial holes 28 corresponding to the branch pipe 2 through the upper pumping and inflating chamber 25 and the lower switching chamber 26; the pumping and inflating dual-purpose air pump 12 is inflated, and the pressurized airbag 6 is expanded under the conveying action of the branch pipe 2. The expanded pressurized airbag 6 squeezes and pushes the pressurized plate 7, driving the pressurized plate 7 to move downward. The downwardly moved pressurized plate 7 adjusts the pressure in the guide cylinder 10 and the detection cylinder 1 to achieve the adjustment of the detection pressure; and when the pressurized airbag 6 expands and pushes the pressurized plate 7 downward, the reset slide rod 31 slides outward from the reset sleeve 30, and the reset spring 32 is in a stretched state;

[0065] (5) After completing the above-mentioned water adding and pressurizing actions, check whether there is water on the bottom wall of the detection tube 1;

[0066] (6) After the test is completed, the dual-purpose air pump 12 is used to pump air, and the pressurized airbag 6 contracts at this time, and the pressurized plate 7 is driven to move up and return to its original position under the action of the return spring 32; then, under the action of the switching motor 23, the switching adjustment plate 24 is driven to rotate to block the branch holes 28 corresponding to the branch pipes 2 and 3, and the dual-purpose air pump 12 pumps air to drive the water-adding airbag 5 to contract; at this time, the one-way pressure control mechanism 38 of the branch pipe 1 is subjected to reverse pressure, and the pressure blocking plate 40 blocks the water inlet 41 of the branch pipe 1, while the one-way pressure control mechanism 38 of the branch pipe 2 and the return pipe 35 is subjected to positive pressure. The pressure blocking plate 40 is opened under the action of the positive pressure, thereby pumping the test water above the waterproof membrane or in the test tube 1 back into the water storage tube;

[0067] (7) Finally, the switching motor 23 drives the switching adjustment plate 24 to rotate until the branch holes 28 corresponding to the branch pipes 1 and 2 are blocked, and then the air is evacuated by the dual-purpose air pump 12 to shrink the sealing airbag 19, so that the sealing airbag 19 seals the gap between the guide tube 10 and the detection tube 1. Under the action of the electric lifting cylinder 47, the guide tube 10 is pulled out of the detection tube 1, and the waterproof membrane is taken out from the detection tube 1.
