Description

Technical Field

[0001] This invention relates to the field of material performance testing technology, and in particular to a testing device for the performance of waterproof materials. Background Technology

[0002] Waterproofing materials are part of the building's envelope, designed to prevent the penetration of rainwater, snowmelt, and groundwater, as well as the erosion of moisture, steam, and other harmful liquids in the air. Before use, waterproofing materials need to be tested for their waterproofing performance to prevent quality problems from arising during use.

[0003] There are two commonly used testing methods: one is to directly drop water onto the coated test block and observe when it leaks; the other is to immerse the coated and cured test block in water.

[0004] The method of detecting leaks by directly dripping water onto a coated test block and observing when it leaks is inefficient and difficult to determine the limits due to the inability to perform pressure tests (the test results have limited reference value); moreover, the assembly process is cumbersome, time-consuming and labor-intensive.

[0005] The method of immersing the coated and cured paint in water cannot accurately determine the waterproof limit of the paint. It is also time-consuming and inefficient. The only way to determine the limit is to take it out and observe it after soaking for a period of time. However, once it is taken out and put back in for testing, the accuracy of the test results will be compromised.

[0006] In summary, the existing technology lacks a testing device for waterproof materials that has relatively high testing efficiency, convenient sample block assembly and disassembly, low labor intensity during use, and can perform pressure tests with good accuracy. Summary of the Invention

[0091] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0092] For ease of description, "test block 001" will be used in the following text to refer to "the test block for testing the paint after oiling". The test block is a rectangular block.

[0093] Example 1

[0094] like Figures 1 to 6 As shown, the testing device for the performance of waterproof materials in this application includes a test chamber 100, a test block positioning assembly 200, a power assembly, and a control unit.

[0095] The test chamber 100 is a rigid chamber with an inlet / outlet pipe 110 connected to a water pump on one side. The top has an opening 130 for easy insertion of the test block 001, and a top cover 140 is fixed to the opening 130. The top cover 140 closes the opening 130 and has an exhaust valve 141 for venting gas from the test chamber 100 to allow for the injection of test water. One or more side openings 150 are located on one side of the test chamber 100, and a top cover 140 is fixed to the side opening. A positioning support tube 160 is provided; the positioning support tube 160 is a rigid tube body, corresponding one-to-one with the side opening 150, and is arranged horizontally, with one end edge fixed to the edge of the side opening 150; a sealing plate 161 is fixed to the end of the positioning support tube 160 away from the side opening 150; the positioning support tube 160 and the sealing plate 161 together seal the side opening 150; the sealing plate 161 is made of transparent material, and the state of the test block 001 inside the test chamber 100 can be observed through the sealing plate 161 during use;

[0096] The test chamber 100 is also fixed with a pressure testing component 120, which is a pressure gauge used to detect the water pressure inside the test chamber 100.

[0097] The test block positioning component 200 is fixed on the test chamber 100 and near the side opening 150, and is used to support and fix the test block 001. It includes a fixing component 210, a supporting ring 230, an inner fixing ring 240, and a wax pumping component 250.

[0098] The supporting ring body 230 is a rigid ring body with a U-shape as its main body. It is fixed to the inner side wall of the test chamber 100 by the fixing component 210. After fixing the test block 001, the supporting ring body 230 closes the side opening 150 from the inside of the test chamber 100.

[0099] The inner fixing ring 240 is fixed to the inner wall of the supporting ring body 230. It is a soft ring body filled with paraffin wax and equipped with a heating component for melting the paraffin wax. The internal space is connected to the wax pumping assembly 250. The main body of the wax pumping assembly 250 is a pump, which is used to change the amount of paraffin wax in the inner fixing ring 240 by pumping, thereby controlling the expansion and contraction of the inner fixing ring 240. In use, the inner fixing ring 240 expands to surround and fix the test block 001.

[0100] The power assembly is used to provide power for the operation of each component of the waterproof material performance testing device of this application, and the control unit plays the role of controlling the coordinated operation of each component of the waterproof material performance testing device. Both are existing technologies and will not be described in detail here.

[0101] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0102] Preferably, the fixing component 210 is a bolt.

[0103] Furthermore, a rubber sealing gasket 220 is positioned between the bearing ring 230 and the inner wall of the test chamber 100.

[0104] Furthermore, the bearing ring 230 is provided with a conveying channel 231, the inner wall of the conveying channel 231 is densely covered with electric heating wires, and the inner fixing ring 240 is connected to the wax pump assembly 250 through the conveying channel 231.

[0105] Furthermore, the inner fixing ring 240 includes a rigid retaining ring 241, a heating element 242, a heat-conducting medium, and an annular soft sheet 243. The rigid retaining ring 241 is a U-shaped rigid sheet-like ring, fixed to the wall of the inner ring of the supporting annular body 230, forming an U-shaped annular space together with the wall of the inner ring of the supporting annular body 230, which plays the role of conducting heat and preventing the annular soft sheet 243 from being burned. The heating element 242 is an electric heating wire or electric heating sheet, fixed to the wall of the inner ring of the supporting annular body 230 and located in the annular space formed by the rigid retaining ring 241 and the supporting annular body 230, and is heated and melted under the control of the control unit. The inner fixing ring 240 contains paraffin wax; the heat-conducting medium, which is a solid, liquid, and / or gaseous medium, is filled in the annular space formed by the rigid retaining ring 241 and the supporting annular body 230, and is used to conduct heat; the annular soft sheet 243 is an annular elastic sheet made of rubber, with both edges fixed to the inner wall of the supporting annular body 230, forming a U-shaped annular space together with the inner wall of the supporting annular body 230; the annular space formed by the annular soft sheet 243 covers the annular space formed by the rigid retaining ring 241; the space formed by the annular soft sheet 243, the rigid retaining ring 241, and the supporting annular body 230 is filled with paraffin wax.

[0106] Furthermore, the wax pump assembly 250 includes a pump body, a paraffin chamber, and a wax delivery hose. The pump body uses the wax delivery hose to adjust the amount of paraffin in the inner fixing ring 240 and the paraffin chamber. The pump body, the paraffin chamber, and the wax delivery hose are all equipped with electric heating wires for melting paraffin.

[0107] When using it, the testing method is as follows;

[0108] 1. Apply the waterproof material to be tested evenly to the surface of the test block, let it dry, and hang it up to cure, trying to avoid abrasion of the coating (when hanging, it can be fixed by clamping at multiple points).

[0109] 2. Hold the test block 001 and let it pass through the inner fixing ring 240. Then control the operation of the wax pump assembly 250 to make the inner fixing ring 240 expand and tightly fit onto the test block 001, thereby fixing the test block 001 in place. (When the inner fixing ring 240 is fitted onto the test block 001, it is preferable to abut against the clamped part of the test block 001 during maintenance to avoid affecting the test results due to wear of the test block 001). Seal the edges with a mixture of paraffin wax and rosin (preferably in a 1:1 ratio).

[0110] 3. Open the exhaust valve 141 and fill the test chamber 100 with water through the inlet and outlet pipes 110. After the chamber is full, close the exhaust valve 141 and turn on the water pump (pressurization pump) to continue filling the chamber. At the same time, observe the pressure gauge and test block 001.

[0111] 4. After pressurizing for a specific time or to a specific pressure (the time and pressure can be adjusted freely according to the actual situation), observe the test block 001 from the sealed plate 161 to see if the waterproof coating has no leakage or bulging, and then determine whether it is qualified.

[0112] Example: When the water pressure reaches 0.6MPa, the uncoated test block leaks a lot of water; when the water pressure inside the test box reaches 1.5MPa, the test block covered with waterproof material is deemed qualified if there is still no leakage or bulging.

[0113] Preferably, the test chamber 100 has two upper openings 150 and two test block positioning components 200, which can simultaneously test the waterproof performance of different types of waterproof materials under the same conditions.

[0114] Preferably, multiple test chambers 100 can be used in combination to simultaneously test the waterproof performance of the same waterproof material under different water pressure conditions.

[0115] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0116] This invention solves the technical problems of existing waterproof material performance testing devices, such as relatively low testing efficiency, cumbersome sample assembly and disassembly process, high labor intensity during use, inability to perform pressure testing, and relatively poor testing accuracy. It achieves the technical effect of waterproof material performance testing devices with relatively high testing efficiency, convenient sample assembly and disassembly, low labor intensity during use, ability to perform pressure testing, and relatively good testing accuracy.

[0117] Test block 001 can be quickly disassembled and used with minimal damage and minimal impact on test results.

[0118] Example 2

[0119] To further reduce the cumbersomeness and labor intensity of the testing device for the waterproof material performance of this application during use, and to improve the sealing effect, this application embodiment optimizes and improves the structure of the test block positioning component 200 based on the above embodiment, enabling it to automatically apply a mixture of paraffin and rosin, specifically as follows:

[0120] like Figure 7 and Figure 8 As shown, the test block positioning assembly 200 also includes an outer ring 260; the outer ring 260 is an annular elastic sheet made of rubber, with both edges fixed to the inner wall of the supporting annular body 230, forming a U-shaped annular space together with the inner wall of the supporting annular body 230; the annular space formed by the outer ring 260 covers the annular space formed by the annular soft sheet 243; the space enclosed by the annular soft sheet 243, the outer ring 260, and the supporting annular body 230 is filled with a mixture of paraffin wax and rosin; the outer ring 260 has one or more rows of output holes 261 near its edge, the output holes 261 being through holes for supplying paraffin wax. A mixture of wax and rosin is output; the outer ring 260 near the annular sheet 243 or the annular sheet 243 near the outer ring 260 is densely covered with partition blocks 262, which are rubber soft blocks used to form fluid channels and prevent contact between the outer ring 260 and the annular sheet 243; the space enclosed by the annular sheet 243, the outer ring 260 and the supporting annular body 230 is connected to the pumping assembly 270, which includes a liquid pump, a mixture storage chamber and a delivery hose. The liquid pump uses the delivery hose to pump the mixture of paraffin and rosin into the space enclosed by the annular sheet 243, the outer ring 260 and the supporting annular body 230.

[0121] In use, the operation of the control pump wax assembly 250 causes the inner fixing ring 240 to expand and tightly fit onto the test block 001, thereby fixing the test block 001. Then, the operation of the control pump assembly 270 causes the discharge hole 261 to discharge the mixture of paraffin and rosin. After that, the control of the annular soft sheet 243 to expand and contract repeatedly causes the mixture of paraffin and rosin to fill the gap between the inner fixing ring 240 and the test block 001 more evenly.

[0122] Example 3

[0123] Considering that the coating, maintenance and assembly processes may cause wear on the test block 001, especially at the corners, which may seriously affect the actual test results and test accuracy; in order to reduce test errors (further control variables), when fixing the test block 001, the four edges away from the side opening 150 are covered by the inner fixing ring 240.

[0124] To extend the service life of the inner retaining ring 240, preferably, as follows: Figure 10 and Figure 11 As shown, the annular soft sheet 243 is composed of three strips spliced ​​together. The three strips are arranged side by side. The strips on both sides are made of elastic rubber, and the strip in the middle is made of plastic. For ease of description, the strip in the middle is defined as the anti-wear sheet 263. In use, the anti-wear sheet 263 abuts against the edge of the test block 001.

[0125] Preferably, the outer ring 260 is composed of three strips joined together, with the three strips arranged side by side. The strips on both sides are made of elastic material, and the strip in the middle is made of plastic sheet. For ease of description, the strip in the middle is defined as the anti-wear sheet 263. In use, the anti-wear sheet 263 abuts against the edge of the test block 001.

[0126] Preferred, such as Figure 9 As shown, the inner fixing ring 240 also includes a partition plate 280, which divides the space inside the inner fixing ring 240 for storing paraffin wax into two parts. The divided spaces are both annular, and each space is connected to the wax pump assembly 250. In use, the two spaces expand and contract independently.

[0127] Example 4

[0128] To make the experimental results more accurate and clearer (and easier to record), and to further control variables, this application embodiment adds a shooting lens 300, an air conditioning assembly 400, a shifting nail plate 500, and a positioning support plate 600 to the above embodiment; specifically:

[0129] like Figures 12 to 14As shown, the camera lens 300 is positioned inside the positioning support tube 160, and is directed to take pictures of the test block 001, and is connected to the control unit via signal.

[0130] The air conditioning component 400 is an air conditioning system, which is connected to the internal space of the positioning support tube 160 and is used to adjust the air temperature and humidity inside the positioning support tube 160.

[0131] The displacement nail plate 500 includes a positioning rod and a nail plate; the nail plate is positioned on the positioning support tube 160 or the closed plate 161 by the positioning rod; the positioning rod is used to drive the nail plate to move toward the test block 001 in a timely manner so that it approaches and punctures the test block 001, thereby puncturing any bulges that may exist on the test block 001; the positioning rod is preferably a horizontally arranged electric telescopic rod structure that extends and retracts under the control of the control unit; the nail plate is arranged longitudinally.

[0132] The positioning support plate 600 is a longitudinally arranged hard or soft sheet, with its top and bottom positioned on the inner wall of the positioning support tube 160 and closely attached to the test block 001. The positioning support plate 600 has a hole whose length and width are both larger than the length and width of the surface of the test block 001 closest to the positioning support plate 600. A water-absorbing color-changing sheet 610 is fixed in this hole. The water-absorbing color-changing sheet 610 is made of paper, and the color of the water-absorbing area will darken after absorbing water, preferably blue. In use, the water-absorbing color-changing sheet 610 is pressed against the surface of the test block 001 closest to the positioning support plate 600 and covers that surface.

[0133] The water-absorbing color-changing sheet 610 is replaceable and can be attached to the positioning support sheet 600 with adhesive.

[0134] Furthermore, the positioning support tube 160 has a built-in temperature and humidity sensor that is signal-connected to the control unit.

[0135] When using the waterproof material performance testing device of this application embodiment:

[0136] First, replace the water-absorbing color-changing sheet 610, then insert the test block 001 so that it abuts against the water-absorbing color-changing sheet 610; then fix the test block 001; then use the air conditioning component 400 to adjust the temperature and humidity in the positioning carrier tube 160 (to the target value); then control the inlet and outlet pipes 110 to introduce water and pressurize; when the target test time or pressure is reached, record the time and the water pressure in the chamber, and use the imaging lens 300 to photograph the state of the water-absorbing color-changing sheet 610 at this time; then control the shifting nail plate 500 to pierce the water-absorbing color-changing sheet 610, thereby puncturing any bulges on the test block 001 and resetting it; within 3 seconds, photograph the water-absorbing color-changing sheet 610 again to record its state; the quality of the coating can be judged more intuitively based on the color-changing area of ​​the water-absorbing color-changing sheet 610.

[0137] Example 5

[0138] like Figure 15 and Figure 16 As shown, in order to further improve the practicality of this application and further reduce the labor intensity during use, the positioning support piece 600 in this application embodiment has been optimized and improved, specifically as follows:

[0139] The positioning support tube 160 is provided with a through groove 162 at the top and bottom near the test box 100. The through groove 162 is a through groove. Both through grooves 162 are provided with groove sealing members 163 that close the two grooves. The groove sealing member 163 is preferably a strip-shaped bladder that expands and contracts under the control of the control unit.

[0140] The positioning support tube 160 is provided with a shifting drum 620 at the top and bottom near the test box 100. The shifting drum 620 is a horizontally arranged cylindrical roller that rotates under the control of the control unit and is used to wind up and release the positioning support piece 600.

[0141] The positioning support piece 600 is strip-shaped with multiple square holes spaced at equal intervals. Each square hole has a water-absorbing color-changing sheet 610 fixed on it. The spacing between the water-absorbing color-changing sheets 610 is greater than the diameter of the positioning support tube 160 or the diameter of its outer circle. The two ends of the positioning support piece 600 are respectively wound and positioned on two shifting roll bodies 620.

[0142] Before inserting the test block 001, first control the groove closure 163 to cancel the closure of the penetration groove 162, then control the two shifting rollers 620 to rotate and replace the water-absorbing color-changing sheet 610 located in the positioning bearing tube 160; then control the groove closure 163 to close the penetration groove 162.

[0143] Example 6

[0144] To further improve the practicality of this application and reduce the labor intensity during use, and to achieve batch automatic testing of test block 001 without damaging it before testing, this application embodiment optimizes and improves the structure of the positioning bearing tube 160 based on the above embodiment, and adds a bottom lifting support plate and an insertion component; specifically:

[0145] like Figure 17 and Figure 18 As shown, the top of the positioning support tube 160 is provided with a top input port 164. The top input port 164 is normally closed by a sealing plate 165. The sealing plate 165 rotates under the control of the control unit to open and close the top input port 164.

[0146] Each of the square holes on the positioning support plate 600 is provided with an insertion channel 630. The insertion channel 630 is a rectangular through groove, which is used for the displacement nail plate 500 to pass through and push the test block 001 into the test box 100, and is also used for the passage of new test blocks 001.

[0147] The positioning support tube 160 has a bottom lifting support plate on its inner bottom. The bottom lifting support plate includes a support plate 710, rotating rollers 720, and a lifting telescopic rod 730. The support plate 710 is a horizontally arranged rigid plate located inside the positioning support tube 160 and is horizontally arranged. The rotating rollers 720 are densely distributed on the top of the support plate 710, are horizontally arranged, rotate around their own axis, and rotate under the control of the control unit. The length direction of the rotating rollers 720 is perpendicular to the axial direction of the positioning support tube 160. The lifting telescopic rod 730 is a longitudinally arranged electric telescopic rod that extends and retracts under the control of the control unit, thereby controlling the lifting and lowering of the support plate 710. The lifting telescopic rod 730 is positioned on the positioning support tube 160 and its top is fixed to the bottom of the support plate 710.

[0148] The insertion assembly includes an insertion top tube 800 and an extrusion conveyor 810;

[0149] The insertion top tube 800 is a rigid tube arranged longitudinally, with its bottom edge fixed to the edge of the top input port 164, for supporting and positioning the extrusion conveyor 810.

[0150] The extrusion conveyor 810 consists of two symmetrically arranged components, which together clamp and fix the test block 001. Each extrusion conveyor 810 includes a top rotating wheel 820, a bottom rotating wheel 830, an extrusion rotating column 840, and an outer elastic ring 850. The top rotating wheel 820 and the bottom rotating wheel 830 are both horizontally arranged cylindrical wheels, positioned on the inner wall of the insertion tube 800, one near the top of the insertion tube 800 and the other near the bottom. The outer elastic ring 850 is a rubber ring that fits over the top rotating wheel 820 and the bottom rotating wheel 830 and remains taut. The extrusion rotating column 840 is a cylindrical soft bladder rotatably connected to the inner wall of the insertion tube 800, arranged horizontally at equal intervals, and in multiple quantities, always abutting against the inner wall of the outer elastic ring 850, rotating as the outer elastic ring 850 rotates.

[0151] When using the waterproof material performance testing device of this application embodiment:

[0152] First, multiple test blocks 001 are loaded into the insertion assembly one by one. During loading, one test block 001 is first inserted between the extrusion conveyor bodies 810. After insertion, the outer elastic ring 850 is rotated to move this test block 001 down by a distance of more than 1.3 test blocks 001. Then the second one is loaded. Thereafter, test blocks 001 are loaded in sequence.

[0153] After testing test block 001:

[0154] 1. First, drain the water in the test chamber 100 to below 150 on the side opening;

[0155] 2. Control the inner fixing ring 240 to retract and cancel the fixation of test block 001;

[0156] 3. Control the movement of the positioning support plate 600 so that the insertion channel 630 is in close contact with the test block 001; control the displacement nail plate 500 to press against the test block 001, and push the tested test block 001 into the test box 100.

[0157] 4. Control the top input port 164 to open, control the bottom lifting tray to rise to the top input port 164; control the insertion component and the bottom lifting tray to work together to make the test block 001 detach from the insertion component;

[0158] 5. Control the bottom lifting tray to insert the test block 001 into the inner fixing ring 240 and fix it;

[0159] 6. Control the movement of the positioning support plate 600 so that the new water-absorbing color-changing sheet 610 comes into contact with the test block 001 to be tested;

[0160] 7. Reset all components, adjust the temperature and humidity inside the positioning bearing tube 160, and start a new round of testing.

[0161] Preferably, in order to avoid damage to the test block 001 when the displacement nail plate 500 pushes the test block 001, the positioning bearing tube 160 is also equipped with a built-in electric push rod for pushing the test block 001 to move.

[0162] Example 7

[0163] Considering that although the insertion component in the above embodiments can hold multiple test blocks 001, the number that can be placed is relatively small due to its own structural limitations (placing a large number would increase the overall structure of the device) and is inconvenient to place; to address the above problems, this application embodiment optimizes and improves the structure of the insertion component and the structure of the bottom lifting tray based on the above embodiments, making the placement of test blocks 001 simpler and safer and expanding the number that can be placed; specifically:

[0164] For ease of distinction, the term "transport component 900" will be used in the following text to refer to the placement component.

[0165] like Figures 19 to 22 As shown, the conveying assembly 900 includes a carrier 910, a conveyor belt assembly 920, and a combined piece 930;

[0166] The carrier 910 is a rod-shaped or frame structure, fixed to the outer wall of the positioning carrier tube 160, and is used to support and fix the conveyor belt assembly 920. The conveyor belt assembly 920 is a conveyor belt structure, including an annular conveyor belt. The combined piece 930 is a soft rectangular piece, with one edge fixed to the outer ring surface of the annular conveyor belt, and the spacing between them is equal. The length direction of the combined piece 930 is the same as the width direction of the annular conveyor belt. An adsorption combined column 940 is fixed on the edge of the combined piece 930 away from the annular belt. The adsorption combined column 940 is a soft column with a built-in magnet. When the test block 001 is loaded into the conveyor assembly 900, two combined pieces 930 are used to cover and fix one test block 001. After fixing, the adsorption combined columns 940 of the two combined pieces 930 are combined together.

[0167] Two rotating clamping rods 740 are rotatably connected to the support plate 710 of the bottom lifting support plate. The two rotating clamping rods 740 are symmetrically arranged and rotate around their own axes under the control of the control unit. When rotating, they clamp the test block 001 covered by the assembly plate 930 through the assembly plate 930. Two sliding magnetic blocks 750 are slidably positioned at the top of the support plate 710. The sliding magnetic blocks 750 are permanent magnets or electromagnets. Under the control of the control unit, they slide along the length of the positioning support tube 160, thereby driving the adsorption assembly columns 940 to move away from each other. The rotating rollers 720 are made of rubber.

[0168] In use, the top input port 164 is opened, and the bottom lifting tray is raised to the top input port 164; the conveyor belt assembly 920 is operated to move the new test block 001 directly above the top input port 164; after the bottom lifting tray is raised and approaches the new test block 001, the clamping rod 740 is rotated to clamp and fix the test block 001 to be used through the combination plate 930; the sliding magnetic block 750 is controlled to slide and attract the adsorption combination column 940, causing the adsorption combination column 940 and the combination plate 930 to move away from directly below the test block 001 to be used; the clamping rod 740 is rotated to make the test block 001 slowly fall onto the rotating roller 720.

[0169] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
