Description

Technical Field

[0001] This utility model relates to the field of waterproof testing technology, and in particular to a waterproof testing device. Background Technology

[0002] Basement waterproofing refers to a series of waterproofing measures taken during the construction of underground structures (such as basements, underground garages, subway stations, etc.) to prevent groundwater seepage. Because underground structures are constantly surrounded by groundwater or damp environments, any damage or failure of the waterproofing layer can easily lead to leakage, affecting the building's functionality and structural safety. Therefore, waterproofing testing, as a crucial aspect of waterproofing project quality control, directly impacts the reliability of the entire waterproofing system through the accuracy and comprehensiveness of its testing methods. Waterproofing testing equipment plays a vital role in basement waterproofing construction. As a key element of quality inspection, its testing methods and performance have a decisive influence on the overall sealing and leak-proof capabilities of the waterproofing materials. Especially in the core stage of performance verification after the waterproofing membrane is laid, existing testing equipment is increasingly revealing significant limitations when handling different areas, complex shapes, or large-area waterproofing layers.

[0003] Specifically, existing waterproofing testing devices mostly employ single-point pressure testing. For example, utility model patent CN212432924U discloses a waterproofing testing device for basement waterproofing construction. This device includes a support mechanism, a testing mechanism, a clamping mechanism, and a pressurizing mechanism, enabling localized water storage and pressure testing of the waterproofing membrane. However, this device has significant shortcomings in practical applications: it can only test a fixed location on the waterproofing membrane, failing to achieve multi-point simultaneous testing of the entire laid surface. This results in unrepresentative test results, making it difficult to comprehensively reflect the overall sealing performance of the waterproofing layer.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a new waterproofing testing device. This novel device should, while ensuring testing stability, possess multi-point simultaneous testing capabilities to improve the comprehensiveness and accuracy of the testing. Simultaneously, it should have a flexible and adjustable structure, be convenient and efficient to operate, and be able to adapt to the waterproofing testing needs under various complex working conditions. This would significantly improve the efficiency and quality of waterproofing testing, better meet the practical needs of modern underground construction projects, and provide strong support for the technological advancement of the waterproofing industry. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof testing device that solves the problem that existing technologies can only test a fixed location of the waterproof membrane, and cannot achieve multi-point synchronous testing of the entire laid surface, resulting in test results that lack representativeness and are difficult to fully reflect the overall sealing performance of the waterproof layer.

[0006] To achieve the above objectives, this utility model provides a waterproof testing device, including a base and a support plate. The support plate is connected to the top of the base by four support rods. A lifting bracket is provided at the center of the top of the support plate. Four openings are symmetrically opened on the top of the support plate, and a pressure cylinder is provided at the top of each opening.

[0007] The lifting bracket is connected to the top of the bearing plate through a vertical lifting structure. The four corners of the lifting bracket are connected to four pressure cylinders respectively. The top of the pressure cylinder is provided with a water inlet, and the top of the pressure cylinder is connected to a mounting frame. The top of the water inlet is provided with a pressure plate, and the top of the pressure plate is connected to the mounting frame through a pushing structure.

[0008] The top of the base is connected to four weighing bases corresponding to four openings, and each weighing base is provided with a collection cylinder on its top.

[0009] Each of the openings has a guide cover at its bottom that is bolted to the bottom of the support plate, and the guide cover is conical in shape.

[0010] Each of the openings has a ring fixedly connected to the top of the support plate at its top. A convex ring is fixedly connected to the inner ring of the top of the ring, and the inner diameter of the pressure cylinder is adapted to the outer diameter of the convex ring.

[0011] The vertical lifting structure includes a lifting cylinder installed at the center of the bottom of the support plate, and the output end of the lifting cylinder is connected to the bottom of the lifting bracket.

[0012] The pushing structure includes a pushing cylinder mounted on the top of the mounting bracket, and the output end of the pushing cylinder is connected to the top of the pressure plate.

[0013] Each of the pressure cylinders is connected to a side rod on one side, and a guide rod with one end sliding through the bearing plate is fixedly connected to the bottom of the side rod.

[0014] This utility model discloses a waterproof testing device. By setting four pressure cylinders corresponding to four openings on a support plate, and combining them with a lifting bracket, a pushing structure, and a weighing base, it achieves simultaneous pressure testing of multiple areas of waterproof fabric. This solves the problems of traditional devices that can only perform single-point testing and have poor representativeness of test results, significantly improving the comprehensiveness and accuracy of the test. The pressure cylinders achieve the pressing action through the lifting bracket, which is structurally stable, easy to operate, and improves testing efficiency. The pushing structure can apply controllable pressure to the pressure plate, simulating waterproof performance under various usage environments, enhancing the authenticity and applicability of the test. The combination of the collection cylinder and the weighing base can intuitively reflect changes in seepage volume, facilitating quantitative analysis of waterproof performance and avoiding errors from manual observation. The overall device has a reasonable structure and compact layout, is suitable for testing waterproof materials of different shapes and sizes, meets the needs of modern underground engineering for high-quality waterproof system testing, and provides reliable technical support for improving the quality of waterproof projects.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a waterproof testing device in this embodiment includes a base 1 and a support plate 2. The support plate 2 is connected to the top of the base 1 by four support rods. A lifting bracket 3 is provided at the center of the top of the support plate 2. Four openings 10 are symmetrically opened on the top of the support plate 2. A pressure cylinder 11 is provided on the top of each opening 10.

[0025] The lifting bracket 3 is connected to the top of the bearing plate 2 through a vertical lifting structure. The four corners of the lifting bracket 3 are connected to four pressure cylinders 11 respectively. The top of the pressure cylinder 11 is provided with a water inlet, and the top of the pressure cylinder 11 is connected to the mounting frame 14. The top of the water inlet is provided with a pressure plate 16, and the top of the pressure plate 16 is connected to the mounting frame 14 through a pushing structure.

[0026] The top of the base 1 is connected to four weighing bases 4 corresponding to four openings 10, and each weighing base 4 is provided with a collection tube 5 on its top.

[0027] The working process of the waterproof testing device is as follows: First, the waterproof cloth to be tested is laid on top of the support plate 2, ensuring that it covers the four openings 10 on the support plate 2. Then, the lifting support 3 is moved downward by the vertical lifting structure. The four corners of the lifting support 3 are connected to the four pressure cylinders 11, driving the pressure cylinders 11 to press down synchronously, so that the bottom end of the pressure cylinder 11 tightly presses the waterproof cloth onto the surface of the support plate 2. Next, a certain amount of water is injected into the pressure cylinder 11 through the water inlet at the top. Then, the pushing structure is activated to push the pressure plate 16 to move downward inside the pressure cylinder 11 to simulate the waterproof performance under different pressure conditions. If there is a leakage point in the waterproof cloth, under the action of water pressure, water will pass through the waterproof cloth and flow into the collection cylinder 5 below from the opening 10. At this time, the weighing base 4 located on the base 1 will detect the weight change, thereby determining the size and location of the leakage. The entire testing process can be carried out simultaneously in multiple pressure cylinder 11 areas, realizing multi-point synchronous pressurization and leakage detection, improving the comprehensiveness and accuracy of the test results.

[0028] Example 2

[0029] Please see Figure 1-5As shown in this embodiment, a waterproof testing device has a guide cover 6 at the bottom of each opening 10, which is bolted to the bottom of the support plate 2. The guide cover 6 is conical in shape. Specifically, the conical design of the guide cover 6 at the bottom of each opening 10 allows water to seep through the waterproof cloth and through the opening 10, flowing smoothly along the inclined surface of the conical guide cover 6 into the collection cylinder 5 below. This design not only ensures effective drainage of leaked water, preventing water from stagnating or overflowing inside the support plate 2, but also improves the accuracy and reliability of the testing process, achieving the effect of preventing data errors caused by obstructed water flow paths.

[0030] The vertical lifting structure includes a lifting cylinder 7 installed at the center of the bottom of the support plate 2. The output end of the lifting cylinder 7 is connected to the bottom of the lifting bracket 3. Specifically, the design of connecting the lifting cylinder 7, installed at the center of the bottom of the support plate 2, to the bottom of the lifting bracket 3 enables precise control of the lifting bracket 3 and the pressure cylinders 11 connected to its four corners. The vertical lifting structure allows the operator to easily adjust the height of the pressure cylinders 11 to facilitate the testing of waterproof materials of different thicknesses. This mechanism not only simplifies the operation process and improves work efficiency, but also ensures uniform pressure on the waterproof cloth throughout the testing process, thereby improving the accuracy of the test results.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in this embodiment, a waterproof testing device has a ring 9 fixedly connected to the top of a support plate 2 at the top of each opening 10. A convex ring 8 is fixedly connected to the inner ring of the top of the ring 9. The inner diameter of the pressure cylinder 11 is adapted to the outer diameter of the convex ring 8. Specifically, through the ring 9 fixedly connected to the top of the support plate 2 at the top of each opening 10, the convex ring 8 fixedly connected to the inner ring of the top of the ring 9, and the design that the inner diameter of the pressure cylinder 11 is adapted to the outer diameter of the convex ring 8, the pressure cylinder 11 can achieve precise positioning and stable support through the convex ring 8 during the testing process. This structural design ensures the positional accuracy and stability of the pressure cylinder 11 when applying pressure to the waterproof cloth, thereby improving the testing accuracy and reducing the measurement error caused by the positional deviation of the pressure cylinder 11.

[0033] The pushing structure includes a pushing cylinder 15 mounted on top of the mounting bracket 14. The output end of the pushing cylinder 15 is connected to the top of the pressure plate 16. Specifically, the design of connecting the pushing cylinder 15 mounted on top of the mounting bracket 14 to the top of the pressure plate 16 enables precise control of the downward movement of the pressure plate 16. The pushing cylinder 15 can adjust the downward pressure as needed to simulate different water pressure conditions to test the performance of the waterproof material under different pressures. This design ensures the consistency and controllability of experimental conditions, achieving a more realistic reflection of the performance of the waterproof material in actual use environments.

[0034] Each pressure cylinder 11 is connected to a side rod 13 on one side. A guide rod 12, with one end sliding through the support plate 2, is fixedly connected to the bottom of each side rod 13. Specifically, through the design of the side rod 13 connected to one side of each pressure cylinder 11 and the guide rod 12 fixedly connected to the bottom of the side rod 13 with one end sliding through the support plate 2, the guide rod 12 provides additional guiding support during the up-and-down movement of the pressure cylinder 11, ensuring the stability of the vertical movement of the pressure cylinder 11 and preventing it from shifting or tilting. This structure enhances the overall stability and durability of the device, achieving the requirement of maintaining high-precision detection even under conditions of long-term, frequent use, while reducing maintenance costs and frequency.

[0035] This solution includes the following work process:

[0036] In actual operation, the waterproof cloth to be tested is first laid on top of the support plate 2, ensuring that it covers the four openings 10 on the support plate 2. Then, the lifting cylinder 7 in the vertical lifting structure drives the lifting bracket 3 to move downward. The four corners of the lifting bracket 3 are connected to four pressure cylinders 11, which drive the pressure cylinders 11 to press down synchronously onto the surface of the waterproof cloth and press it tightly. A positioning structure composed of a circular ring 9 and a convex ring 8 is provided between the bottom of the pressure cylinder 11 and the support plate 2 to ensure that the pressure cylinder 11 is stably aligned with the opening 10. Next, a certain amount of water is injected into the cylinder through the water inlet at the top of the pressure cylinder 11. At the same time, the pushing cylinder 15 is activated, and its output end pushes the pressure plate 16 downward to apply controllable pressure to the water in the cylinder, simulating the waterproof performance test under different water pressure environments. If the waterproof cloth has defects or The weak point is that under pressure, water will penetrate the waterproof cloth and flow out from the opening 10 into the collection cylinder 5 set on the base 1 below. At this time, the weighing base 4 will record the weight change in real time to determine the leakage situation. In order to further improve the water flow guidance efficiency, each opening 10 is equipped with a conical guide cover 6 at the bottom, which is fixed to the bottom of the bearing plate 2 by bolts, so that the leaking water flows smoothly into the collection cylinder 5 along the slope, avoiding stagnation or overflow that would cause data errors. In addition, in order to improve the stability of the movement of the pressure cylinder 11, a side rod 13 is connected to one side of each pressure cylinder 11. The bottom of the side rod 13 is fixedly connected to the guide rod 12. The guide rod 12 slides through the bearing plate 2, which plays a guiding and limiting role, preventing the pressure cylinder 11 from shifting or tilting during the up and down movement, thereby ensuring the stability and accuracy of the entire detection process.

[0037] Based on the aforementioned complete structural design and coordinated operation, this device achieves the following significant technical effects: First, the layout of four pressure cylinders 11, four openings 10, and corresponding weighing bases 4 enables simultaneous pressurization and seepage detection of multiple areas of the waterproof fabric, solving the problem of poor representativeness in traditional single-point detection and improving the comprehensiveness and reliability of the detection results; Second, the lifting cylinder 7, as the core component of the vertical lifting structure, can precisely control the height of the lifting bracket 3 and the pressure cylinders 11, facilitating adaptation to waterproof materials of different thicknesses and improving the applicability and ease of operation of the equipment; Third, the pushing structure composed of the pushing cylinder 15 and the pressure plate 16 can simulate various water pressure conditions. The enhanced authenticity and controllability of the detection helps to more accurately assess the performance of waterproof materials in actual use environments. Fourth, the design of the circular ring 9 and the convex ring 8 provides precise positioning support for the pressure cylinder 11, effectively reducing pressure unevenness caused by positional deviations and further improving detection accuracy. Fifth, the guiding structure of the guide rod 12 and the side rod 13 enhances the stability of the vertical movement of the pressure cylinder 11, reduces vibration and wear during equipment operation, extends service life, and reduces maintenance frequency. Sixth, the conical guide cover 6 works in conjunction with the collection cylinder 5 to ensure that leaked water flows smoothly into the weighing base 4 for measurement, avoiding misjudgments caused by chaotic water flow paths. In summary, this waterproof detection device not only solves the problems of multi-point synchronous detection and low detection accuracy in existing technologies, but also significantly improves detection efficiency, accuracy, and equipment stability through multiple structural optimization designs, meeting the actual needs of modern underground construction projects for high-quality waterproof system detection, and has good promotional value and application prospects.
