A bearing frame is fixedly installed at the upper end of the first fixing plate. The waterproof material to be tested for waterproof performance is arranged between the first fixing plate and the second fixing plate.

Specific embodiments

[0030] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Embodiment: A waterproof performance testing device for waterproof membrane materials, comprising a frame body 1. The frame body 1 is bent, and the provided dripping module and fixing module are relatively fixed in position. Specifically, the inner wall of the provided frame body 1 is fixedly connected to the outer wall of the mounting plate 3, the lower inner wall of the provided frame body 1 is fixed to the outer wall of the first fixing plate 12, and the provided frame body 1 is fixedly installed with an external mounting component and can be installed on a desktop or the ground.

[0033] Dripping module, a water source bearing device for conducting a dripping test on a waterproof material 23, including a mounting plate 3 fixedly connected to a frame 1. On the upper side of the mounting plate 3, there is a sealing box 8 for containing water. In the middle of the sealing box 8, there is a water storage tank 801. The upper end sealing of the water storage tank 801 is sealed by a displacement member 9 that is slidably connected relative to the sealing box 8. The outer wall of the displacement member 9 is sealed with the inner wall of the water storage tank 801. And the lower end of the provided water storage tank 801 is sealed by the mounting plate 3. Specifically, the outer wall of the lower end of the sealing box 8 is fixedly connected to the top surface of the mounting plate 3. Thus, a relatively sealed cavity is formed by the displacement member 9 at the upper side position, the mounting plate 3 at the lower side position, and the wall of the water storage tank 801 for temporarily storing the water source.

[0034] Refer to the appendix Figures 1-8 As shown in the figure, specifically, a water inlet pipe 901 is installed at the upper end of the displacement member 9. The water inlet pipe 901 is in communication with an external water source and can be connected to the port of a faucet through a connecting pipe to simulate the waterproof performance of the waterproof material 23 under normal water quality conditions. Particularly, for different regions, the acidity and alkalinity of the water quality are different. Different acid-base rainwaters can be configured through external equipment. At this time, a water source with a certain acidity and alkalinity can be pumped into the interior of the sealing box 8 through an external water pump, and the dripping module is used to simulate the dripping test of rainwater in the actual environment to test the performance of the waterproof material 23.

[0035] Particularly, the above-mentioned device can conduct a dripping test on different water qualities to test the waterproof performance of the waterproof material 23. In order to more closely simulate the actual environmental test, in actual rainy weather, when rainwater drops from a high altitude, it has a certain kinetic potential energy. At this time, the rainwater dripping normally using this device cannot well simulate raindrops with a certain kinetic potential energy. Therefore, in order to better simulate the actual situation, there is also a displacement member 9 in the sealing box 8. The displacement member 9 can be vertically adjusted in the sealing box 8 through an external driving mechanism. Here, it is necessary to coordinate and adjust the positional relationship between the mounting plate 3 and the adjusting member 4. On the premise of ensuring the same precipitation amount, that is, ensuring the coincidence degree of the through slots between the mounting plate 3 and the adjusting member 4, under the action of the driving mechanism, the driving mechanism can adopt a cylinder, and a connecting block 10 fixedly connected to the output end of the driving mechanism is fixedly connected to the top surface of the displacement member 9. The height of the displacement member 9 can be adjusted to make it move downward uniformly. Then, the water source inside the sealed cavity, under the pressure of the displacement member 9, can drive the simulation of rainwater dripping test with a certain kinetic potential energy downward from the position of the coincident through slot, so that the falling water source has a certain kinetic potential energy, thus better simulating the actual working environment and obtaining more accurate waterproof performance data of the waterproof material 23.

[0036] Refer to the appendixFigures 1-8 As shown, the water inside the sealed box 8 freely drips under the action of gravity through the mounting plate 3, and the adjusting member 4 provided inside the mounting plate 3 simulates different dripping degree tests by adjusting the staggered relationship between the middle parts of the mounting plate 3 and the adjusting member 4. The mounting plate 3 and the adjusting member 4 are movably connected, and through grooves are respectively formed in the middle parts of the bottom surfaces of the mounting plate 3 and the adjusting member 4 to facilitate the free dripping of the water in the sealed box 8. The connection between the mounting plate 3 and the sealed box 8 is sealed. As an implementation manner, the through groove group can be embodied as the first circular groove 302 formed in the middle of the mounting plate 3 and the second circular groove 401 formed through the middle of the adjusting member 4. It should be noted that a sliding groove 301 is formed inside the mounting plate 3, and the outer wall of the middle part of the adjusting member 4 is slidably matched with the inner wall of the sliding groove 301. By adjusting the positional relationship between the adjusting member 4 and the mounting plate 3, the overlapping degree between the first circular groove 302 and the second circular groove 401 is adjusted, so that the water source filling the sealed cavity composed of the water storage tank 801, the displacement member 9, and the mounting plate 3 can drip from the overlapping part between the two circular grooves, thereby simulating the actual rain dripping scenario. The holding plates 5 fixedly installed on the upper sides of both ends of the adjusting member 4 can facilitate the adjustment, and the overlapping plate 2 fixedly installed on the frame body 1 can overlap the adjusting member 4 extending outside the mounting plate 3. It should be noted that a limiting strip 7 is fixedly installed at the lower end position of the mounting plate 3, and the limiting strip 7 is adapted to the outer track of the formed first circular groove 302 to limit the area of the dripping water, so that it can drip more accurately on the upper side of the waterproof material 23 fixed in the fixed module. It should be noted that a baffle 6 is installed on one side of the limiting strip 7 on the bottom surface of the mounting plate 3, which can also limit the area range of the dripping water.

[0037] Refer to the appendix Figures 1-8 ​As shown, there can be multiple sets of fixed modules, which are fixing devices for fixing the waterproof material 23 whose waterproof performance is to be verified. The fixing device includes a first fixing plate 12 and a second fixing plate 18 that are movably connected. A bearing frame 11 is fixedly installed at the upper end of the first fixing plate 12. The waterproof material 23 to be tested for waterproof performance is arranged between the first fixing plate 12 and the second fixing plate 18. The distance between the second fixing plate 18 and the first fixing plate 12 is adjusted by a hydraulic cylinder 20 at the lower end of the second fixing plate 18. The lower end of the first fixing plate 12 is fixedly connected to a frame 15. The second fixing plate 18 is movably connected to the frame 15. It also includes a pre-fixing member 13 arranged between the first fixing plate 12 and the second fixing plate 18. The pre-fixing member 13 is fixedly connected to the first fixing plate 12. A magnetic adsorption relationship is maintained between the bottom surface of the lower end of the pre-fixing member 13 and the bottom surface of the second fixing plate 18 through a magnetic adsorption block 1301. A corresponding magnetic block is also fixedly installed at the lower end of the second fixing plate 18, and magnetic adsorption exists between this magnetic block and the magnetic adsorption block 1301. When the distance between the two fixing plates is not adjusted by the hydraulic cylinder 20, there is a certain gap between the second fixing plate 18 and the first fixing plate 12, which facilitates the actual installation of the horizontal plate 21. During the actual use process, the sheet-shaped waterproof material 23 to be tested is bonded to the outer wall of the horizontal plate 21. And due to the movable connection relationship between the first fixing plate 12 and the second fixing plate 18 provided, and the second fixing plate 18 can be driven by the provided hydraulic cylinder 20 to approach the first fixing plate 12, so that the provided horizontal plate 21 can be clamped and fixed. Particularly, on the bearing frame 11 fixedly installed at the upper end of the first fixing plate 12 and the bearing groove 1101 opened on the bearing frame 11, the water dripping from the dripping module can be received. It should be noted that the upper end of the bearing groove 1101 is open, and when the positions of the first fixing plate 12 and the second fixing plate 18 are adjusted, the waterproof material 23 bonded to the upper side of the horizontal plate 21 can directly contact the water dripping from the upper position and receive it. And it should be noted that a water outlet pipe 14 is fixedly installed on one side of the first fixing plate 12. The water outlet pipe 14 is communicated with the inside of the bearing groove 1101, and a control switch is installed on the water outlet pipe 14, which can discharge the water in the bearing groove 1101 or keep it closed, so that the bearing groove 1101 is relatively sealed, thereby being able to test the load-bearing waterproof performance of the waterproof material 23. When the control switch is in the open state, it can simulate normal water flow and test the waterproof performance of the waterproof material 23.

[0038] Refer to the appendix Figures 1-8As shown in the figure, the horizontal plate 21 is arranged between the middle parts of the first fixed plate 12 and the second fixed plate 18, and can realize the sealed connection with the first fixed plate 12 and the second fixed plate 18 through the hydraulic cylinder 20 cooperating with the sealing mechanism arranged between the first fixed plate 12 and the second fixed plate 18. A moving plate 19 is fixedly installed on the output end of the hydraulic cylinder 20, and the moving plate 19 is fixedly connected with the outer wall of the lower end of the second fixed plate 18. It is worth noting that the sealing mechanism includes an annular sealing strip 1801 fixedly installed on the upper end of the second fixed plate 18. When the hydraulic cylinder 20 drives the second fixed plate 18 to move upward, the upper end of the annular sealing strip 1801 can be connected to the bottom surface of the horizontal plate 21. And a sealing ring is also arranged at the lower end of the first fixed plate 12 provided, and during the test process, the sealing performance of the connection position between the first fixed plate 12 and the waterproof material 23 can be ensured.

[0039] Refer to the appendix Figures 1-8 As shown in the figure, between two adjacent fixing modules can be fixed through the clamping member 17 arranged between the middle parts of two adjacent frames 15, and the effective bearing surfaces of the multiple bearing frames 11 provided correspond to the positions of the through groove groups opened. A relief plate 16 is rotatably connected to the upper side of one end of the frame 15, and the position of the relief plate 16 corresponds to the position of the horizontal plate 21 installed between the middle parts of the first fixed plate 12 and the second fixed plate 18. Through the relief plate 16 rotatably connected to the frame 15 provided, the installation of the horizontal plate 21 can be facilitated.

[0040] Refer to the appendix Figures 1-8 As shown in the figure, a guide rod 22 is fixedly installed on the outer wall of the first fixed plate 12, and the guide rod 22 is rotatably connected with the frame 1. It is worth noting that due to the fixed connection relationship between the first fixed plate 12 and the frame 1 provided, the sliding fit relationship between the guide rod 22 and the inner wall of the arc-shaped groove 101 opened on the outer wall of the frame 1 can enable the fixing module to rotate at an angle relative to the frame 1, so that the waterproof material 23 kept relatively fixed with the fixing module is in a certain inclined state, and better simulate the actual installation of the waterproof material 23 on a waterproof surface with a certain slope, and better obtain the actual test data. It is worth noting that for the specific test parameters, after the test, the water content of the horizontal plate 21 is measured for data recording.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
