[0013] This membrane material water pressure resistance testing device features a clamping assembly, including a screw mechanism comprising a motor and a screw. When the screw operates normally, it drives a moving strip. One side of the membrane material is placed under the bottom of two floppy disks. Under the action of a first spring, the bottom of the floppy disks adheres to the top of the membrane material, thus positioning one side of the membrane. Simultaneously, a second spring adjusts the position of the flattening roller, moving it to a designated height. The other side of the membrane material is then passed through the bottom of the flattening roller, and the roller is released, allowing the outer side of the flattening roller to adhere to the top of the membrane. During normal operation of the screw mechanism, the moving strip can be used to... The dynamic pressure roller rotates on top of the membrane material, flattening it and preventing wrinkles on the membrane surface from affecting the accuracy of the water resistance test. Simultaneously, a sealing gasket ensures a tight seal with the bottom of the membrane, preventing moisture from entering through gaps and interfering with the test. This solves the problem of some water pressure testing devices where wrinkles appear on certain membranes during placement, leading to errors in the test data, affecting the assessment of membrane quality, and ultimately reducing the efficiency of the water pressure test.

[0022] Figure 4 This is a schematic diagram showing the structural connection between the sealing gasket and the third fixing rod of this utility model; Figure 5 This utility model Figure 1 The diagram shows an enlarged view of the structure at point A. The membrane material water pressure resistance testing device includes a base 1, a test groove 2 fixedly connected to the top of the base 1, a PLC controller 3 on one side of the test groove 2, an observation window 4 inside the test groove 2, a water storage tank 5 fixedly connected to the top of the base 1, and a clamping assembly 6 inside the test groove 2. The clamping assembly 6 includes a lead screw mechanism 601, a fixing bar 602, a connecting plate 603, a moving bar 604, a fixing plate 605, and a sealing gasket 606. The lead screw mechanism 601 is located inside the test groove 2, the fixing bar 602 is located outside the lead screw mechanism 601, the connecting plate 603 is located on top of the fixing bar 602, the moving bar 604 is located outside the lead screw mechanism 601, the fixing plate 605 is located on top of the moving bar 604, and a sealing gasket 606 is located on one side of the inner wall of the test groove 2.

[0023] In this embodiment: When the operator conducts a water pressure resistance test on the membrane material, firstly, one side of the membrane material is placed on top of the fixing strip 602. Simultaneously, the positions of the connecting plate 603 and the floppy disk 11 are adjusted using the first spring 10. After one side of the membrane material is placed on top of the fixing strip 602, the connecting plate 603 is released. Under the elastic force of the first spring 10, the bottom of the floppy disk 11 is brought into contact with the top of the membrane material. Then, the positions of the two fixing plates 605 are adjusted using the second spring 13 and the second fixing rod 12, causing the flattening roller 15 to move to the specified height. Finally, the flattening roller 15 is released. The bottom of the flattening roller 15 is then placed against the top of the membrane material. The operator then starts the screw mechanism 601, which in turn causes the moving bar 604 to move the flattening roller 15. This causes the flattening roller 15 to rotate on top of the membrane material, flattening it and preventing wrinkles from affecting the accuracy of the water pressure resistance test. After the moving bar 604 moves to the designated position, it enters the test groove 2. Under the elastic force of the third spring 19, the top of the sealing gasket 606 is tightly placed against the bottom of the membrane material, allowing the membrane material to be tested for water pressure resistance.

[0024] As a technical optimization of this utility model, a movable block 7 is provided on the outer side of the lead screw mechanism 601, a fixed block 8 is fixedly connected inside the test groove 2, a first fixed rod 9 is fixedly connected inside the fixed block 8, a first spring 10 is sleeved on the outer side of the first fixed rod 9, and the front surface of the fixed block 8 is fixedly connected to the rear surface of the fixed strip 602.

[0025] In this embodiment: When the lead screw mechanism 601 is operating normally, the moving block 7 can drive the moving strip 604 to move, thereby allowing the flattening roller 15 to move on the top of the film material. At the same time, under the action of the fixing block 8, the fixing strip 602 can remain stable without affecting the normal operation of the lead screw mechanism 601. Under the elastic force of the first spring 10, the bottom of the floppy disk 11 can be tightly attached to the top of the film material, thereby positioning one side of the film material and facilitating the flattening operation.

[0026] As a technical optimization of this utility model, the outer side of the first fixing rod 9 is slidably connected to the inside of the connecting plate 603, one end of the first spring 10 is welded to the top of the connecting plate 603, and a floppy disk 11 is provided at the bottom of the connecting plate 603.

[0027] In this embodiment: Under the elastic force of the first spring 10, it is convenient for the operator to adjust the position of the connecting plate 603, so that the bottom of the floppy disk 11 can be attached to the top of the membrane material, thereby positioning and fixing the membrane material without damaging it.

[0028] As a technical optimization of this utility model, the top of the moving bar 604 is fixedly connected to the upright plate 14, and the interior of the moving block 7 and the upright plate 14 are both fixedly connected to the second fixing rod 12. The outer side of the second fixing rod 12 is fitted with a second spring 13, and the bottom of the fixing plate 605 is provided with a flattening roller 15.

[0029] In this embodiment: Under the elastic force of the second spring 13, the fixed plate 605 can move, thereby adjusting the height of the flattening roller 15. After the membrane material is placed in the designated position, the fixed plate 605 is released, so that the bottom of the flattening roller 15 fits tightly with the top of the membrane material. Then, when the screw mechanism 601 is operating normally, the flattening roller 15 can flatten the membrane material, preventing wrinkles in the membrane material from affecting the accuracy of the water pressure resistance test.

[0030] As a technical optimization of this utility model, a soft pad 16 is provided at the bottom of both the fixed strip 602 and the moving strip 604. A side block 17 is fixedly connected to one side of the sealing pad 606. A third fixed rod 18 is slidably connected inside the side block 17. The top and bottom of the third fixed rod 18 are fixedly connected to the inside of the test groove 2. A third spring 19 is sleeved on the outside of the third fixed rod 18.

[0031] In this embodiment: after the membrane material is flattened, the connecting plate 603 is pulled to separate the floppy disk 11 from the membrane material. At the same time, under the action of the third spring 19, the sealing gasket 606 moves, so that the top of the membrane material is tightly connected to the floppy gasket 16 and the bottom of the membrane material is tightly connected to the top of the sealing gasket 606. Meanwhile, a sealing block is provided on the outer side of the side block 17 and a sealing block is provided at the part that contacts the third fixing rod 18, so that moisture will not enter the bottom of the membrane material through the gap between the membrane material and the sealing gasket 606.

[0032] As a technical optimization of this utility model, a supplementary light 20 and a pressure sensor 21 are respectively provided at the bottom of the inner cavity of the test tank 2. An insertion hole 22 is opened inside the test tank 2. A sealing ring 23 is provided on the inner wall of the insertion hole 22. An insertion rod 24 is slidably connected to the inner ring of the sealing ring 23. A sealing plate 25 is fixedly connected to the top of the insertion rod 24. A drain pipe 26 is connected to one side of the test tank 2. A first solenoid valve 27 is provided on the outer side of the drain pipe 26.

[0033] In this embodiment: Under the effect of the supplementary light 20, it is convenient for the staff to observe the water seepage points of the membrane material through the observation window 4. At the same time, when water seepage occurs in the membrane material, the pressure sensed by the pressure sensor 21 will fluctuate, and the staff can record the signal transmitted by the pressure sensor 21, so that the staff can record the water pressure resistance test data of the membrane material in a timely manner.

[0034] As a technical optimization of this utility model, a delivery pump 28 is fixedly connected to the top of the water storage tank 5. The outlet of the delivery pump 28 is connected to a connecting pipe 29. A second solenoid valve 30 is provided on the outside of the connecting pipe 29. A sliding pipe 31 is connected to the end of the connecting pipe 29 away from the delivery pump 28. A rotating pipe 32 is connected to the bottom of the sliding pipe 31. The bottom of the rotating pipe 32 is rotatably connected to the top of the sealing plate 25. The outside of the sliding pipe 31 is slidably connected to the inner wall of the connecting pipe 29. The outside of the sliding pipe 31 is threadedly connected to the inner wall of the rotating pipe 32.

[0035] In this embodiment: under the action of the delivery pump 28, water can be extracted from the water storage tank 5, and then the water can enter the test tank 2 through the connecting pipe 29, the sliding pipe 31 and the rotating pipe 32 to conduct a water pressure test on the membrane material. At the same time, when it is necessary to open the test tank 2, the rotating pipe 32 can be rotated to disengage the sliding pipe 31 from the rotating pipe 32, and then the sliding pipe 31 can be slid, so that the sealing plate 25 can be opened smoothly.

[0036] The working principle of the membrane material water pressure resistance testing device provided by this utility model is as follows:

[0037] When the operator conducts a water pressure resistance test on the membrane material using this device, the membrane material is first cut so that it can be placed inside the test tank 2. Then, one side of the membrane material is placed at the bottom of the floppy disk 11. Under the elastic force of the first spring 10, the bottom of the floppy disk 11 contacts the top of the membrane material, thereby positioning one side of the membrane material. Then, the operator pushes the fixing plate 605, causing it to move to a certain height, allowing the membrane material to pass through the bottom of the flattening roller 15. The fixing plate 605 is then released, allowing the membrane material to... The bottom of the flattening roller 15 can contact the top of the membrane material, which then causes the screw mechanism 601 to start operating. Under the action of the screw mechanism 601, the flattening roller 15 can move, thereby flattening the membrane material. This prevents wrinkles in the membrane material from affecting the accuracy of the water pressure resistance test. At the same time, under the elastic force of the third spring 19, the bottom of the membrane material can be tightly fitted to the top of the sealing gasket 606, thereby preventing moisture from affecting the normal progress of the water pressure resistance test through the gap between the membrane material and the sealing gasket 606.
