Description

Technical Field

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

[0002] Currently, in the process of transforming scientific research results, many prefabricated components are used in newly built or renovated factories, test sites, office buildings, etc. In reality, many steel and concrete components develop leakage problems after a few years of use, causing maintenance, major repairs, increased costs, and disruption to on-site production. Prefabricated components refer to steel, wood, or concrete components prefabricated in a factory or on-site according to design specifications. They are a common building material with wide applications in construction projects. The design and manufacturing of prefabricated components require a series of performance tests.

[0003] Currently, the waterproof performance testing of precast components for building construction is mostly conducted using a spray method that simulates rainy weather. This involves spraying water onto the components continuously for an extended period and observing the water seepage. However, this method has some limitations in practical use and has room for improvement. For example, the angle and position of the spray nozzles used for side-viewing of precast components are mostly fixed, the testing scenarios are relatively limited, and it cannot simulate various rainy weather conditions. Furthermore, it lacks the ability to easily adjust the spray angle and position.

[0004] Accordingly, there is a need in the field for a new waterproof performance testing device to solve the above-mentioned technical problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to address the issue that existing waterproof performance testing devices have a relatively limited effectiveness in testing the waterproof performance of precast engineering components.

[0006] This utility model provides a waterproof performance testing device for testing the waterproof performance of prefabricated components in building engineering. The testing device comprises:

[0007] A testing table, wherein a work surface is formed on the top of the testing table and a water receiving tank is installed at the bottom of the work table;

[0008] A material mounting assembly is used to fix a prefabricated component to be inspected. The material mounting assembly includes a locking mechanism and a first driving component. The locking mechanism is slidably mounted on the first end of the worktable through a first connecting component. The output end of the first driving component is connected to the locking mechanism and is used to drive the locking mechanism to move on the worktable.

[0009] A water supply assembly is provided to supply spray water to the testing platform. The assembly includes a fixed plate, a guide rail, a second drive component, and a spray head. The fixed plate is installed at the second end of the workbench surface. The guide rail is installed on the top of the fixed plate facing the first end of the workbench. The spray head is slidably mounted on the guide rail via a second connector. The output end of the second drive component is fixedly connected to the second connector, allowing the second drive component to drive the spray head to slide along the guide rail, thereby changing the spray position of the spray head. The spray head is connected to the water receiving tank via a water delivery hose, and a water pump is installed on the water delivery hose to supply water from the water receiving tank to the spray head.

[0010] The fixing plate is also equipped with a water immersion mechanism for conducting water immersion tests on the prefabricated components to be tested.

[0011] Based on the above configuration, the positioning mechanism in the material installation assembly can slide on the worktable and is driven by the first drive component to adjust the position of the prefabricated component to be tested, adapting to components of different specifications and improving the flexibility of testing. The spray head in the water supply assembly can slide along the guide rail and is controlled by the second drive component to adjust the spray position, ensuring full coverage of the prefabricated component and improving the accuracy of testing. Through both spray testing and immersion testing, the waterproof performance of the prefabricated component is comprehensively tested, ensuring that the experimental data is closer to the actual working conditions. Furthermore, the spray head is designed as a movable structure, so that the waterproof performance of different areas can be tested, improving the comprehensiveness of testing. Through the automatic adjustment of the first and second drive components, precise positioning can be achieved, improving testing efficiency, reducing manual intervention, and improving the consistency and repeatability of testing.

[0012] In the preferred embodiment of the above-mentioned waterproof performance testing device, the first connecting member is configured as a slide rail structure; the positioning mechanism includes a positioning plate, a positioning clamp, and a positioning rod. The positioning plate is slidably connected to the slide rail structure. The positioning clamp is detachably mounted on the first end of the positioning plate by bolts. The positioning plate has multiple threaded holes to allow the positioning clamp to be adjusted to different positions on the positioning plate. The second end of the positioning plate is provided with a positioning rod, and a clamping space for clamping the prefabricated component to be tested is formed between the positioning rod and the positioning clamp.

[0013] Based on the above configuration, by incorporating slide rails, sliding sleeves, positioning rods, positioning plates, positioning holes, positioning clamps, and hand-tightening bolts, rapid clamping of precast components of different sizes can be achieved. The positioning clamps can be adjusted according to the width of the component, and the position is fixed by hand-tightening bolts, ensuring that the component remains stable and does not move during the inspection process. This improves the flexibility and firmness of clamping, reduces errors, and increases work efficiency.

[0014] In the preferred embodiment of the above-mentioned waterproof performance testing device, the first driving component is a first electric cylinder, and the telescopic end of the first electric cylinder is fixedly connected to the positioning rod so that the telescopic extension of the electric cylinder drives the positioning rod to move.

[0015] Based on the above setup, the extension and retraction of the positioning rod driven by the first electric cylinder enables rapid and precise positioning adjustment. This design enhances the automation and flexibility of the inspection process, avoids errors inherent in manual operation, and improves the stability and accuracy of the equipment. The electric drive system simplifies the operation process and increases work efficiency.

[0016] In the preferred embodiment of the above-mentioned waterproof performance testing device, the first electric cylinder is provided in four sets.

[0017] Based on the above setup, the four sets of first electric cylinders provide stronger driving force and higher stability, ensuring sufficient support for the equipment during waterproof performance testing and allowing the positioning clamp to remain stable under different component sizes. This not only enhances the clamping force but also reduces test deviations caused by equipment instability.

[0018] In the preferred embodiment of the above-mentioned waterproof performance testing device, the second connecting member includes a bushing and a connecting rod. The bushing is slidably sleeved on the guide rail, and the connecting rod is fixedly installed at the bottom of the bushing. The connecting rod is connected to the spray head through a spherical hinge structure so that the spray head can spray movably.

[0019] Based on the above settings, a damping design for the ball head and ball seat is adopted, making the nozzle angle adjustment smoother and more stable. During spraying, the nozzle can flexibly adjust its angle without being affected by resistance, which ensures that the water flow can be sprayed evenly and accurately to all parts of the precast components, simulating more complex rainfall conditions and enhancing the accuracy of waterproof performance testing.

[0020] In the preferred embodiment of the above-mentioned waterproof performance testing device, the second driving component is configured as a multi-stage electric cylinder, and the telescopic end of the multi-stage electric cylinder is fixedly connected to the bushing, so that the telescopic extension of the multi-stage electric cylinder drives the bushing to slide on the guide rail.

[0021] Based on the above setup, the position of the nozzle can be precisely adjusted by driving the sliding sleeve along the optical axis using a multi-stage electric cylinder, ensuring that the sprayed water flow covers all critical parts of the precast component. This design can be automatically adjusted in different scenarios to ensure that the spray position and angle during the testing process meet preset requirements, thus improving the comprehensiveness of the waterproof performance test.

[0022] In the preferred embodiment of the above-mentioned waterproof performance testing device, a water-dividing cavity is formed inside the spray head.

[0023] Based on the above setup, a water distribution chamber is incorporated within the spray assembly, and the spray angle is adjusted via connecting rods and ball heads to ensure a more uniform water flow distribution. This effectively improves the coverage of the sprayed water flow, ensuring that the water flow is uniformly sprayed during waterproof performance testing of precast components, thereby enhancing the accuracy and reliability of the test.

[0024] In the preferred embodiment of the above-mentioned waterproof performance testing device, the immersion mechanism includes a slotted block and a second electric cylinder. The slotted block is configured with a top opening and an opening on the side near the prefabricated component to be tested. The top of the slotted block is used to receive the spray water sprayed from the spray head. The second electric cylinder is mounted on the fixed plate, and the output end of the second electric cylinder is fixedly connected to the side of the slotted block away from the prefabricated component to be tested, so that the second electric cylinder can drive the slotted block to contact or separate from the prefabricated component to be tested by extension and retraction.

[0025] Based on the above setup, the design of the first electric cylinder, the second electric cylinder, the side opening groove, and the concave sealing strip can simulate a water immersion scenario. The extension and retraction of the second electric cylinder controls the movement of the opening groove, allowing it to make close contact with the side of the prefabricated component. The concave sealing strip enhances the sealing effect, ensuring that water will not leak out during the test, simulating a more realistic water immersion environment and improving the accuracy of the waterproof performance test.

[0026] In the preferred embodiment of the above-mentioned waterproof performance testing device, a sealing strip is provided at the bottom of the side of the grooved block that contacts the precast component to be tested.

[0027] Based on the above setup, installing a sealing strip on the side of the slotted block that contacts the precast component effectively improves the sealing of the contact surface, preventing water leakage during simulated immersion tests. The sealing strip design ensures the stability and reliability of the immersion simulation process, enhancing the realism and accuracy of waterproof performance testing.

[0028] In the preferred embodiment of the waterproof performance testing device described above, the second electric cylinder is provided in four sets.

[0029] Based on the above setup, four sets of second electric cylinders are used to drive the contact between the slotted block and the prefabricated component, making the simulated water immersion scenario more accurate and stable. Through synchronous operation, the second electric cylinders ensure that the simulated water level and environment are consistent during the water immersion test, thereby enhancing the reliability and accuracy of the test.

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0038] It should be noted that in the description of this utility model, the terms "middle," "upper," "lower," "left," "right," "inner," and "outer," which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the structure must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] First refer to Figure 1 ,like Figure 1As shown, this utility model provides a waterproof performance testing device for testing the waterproof performance of prefabricated components in building engineering. The device comprises:

[0041] The testing table 1 has a work surface formed on its top and a water receiving tank 2 installed at the bottom of the work surface. It should be noted that the present invention does not impose any restrictions on the specific structure of the testing table 1. Those skilled in the art can set it according to their needs. For example, the testing table 1 can be a circular table or a square table, as long as the testing table 1 can accommodate the testing device and the object to be tested.

[0042] A material mounting assembly is provided to fix a prefabricated component to be inspected. The assembly includes a locking mechanism and a first driving component. The locking mechanism is slidably mounted on the first end of the worktable via a first connecting member. The output end of the first driving component is connected to the locking mechanism to drive it to move on the worktable. It should be noted that this invention does not impose any restrictions on the specific structure of the first driving component. Those skilled in the art can set it according to their needs. For example, the first driving component can be a motor, or it can be an electric cylinder, as long as the first driving component can drive the worktable to move along a certain trajectory on the worktable. In this preferred embodiment, the first driving component is a first electric cylinder 16. The telescopic end of the first electric cylinder 16 is fixedly connected to the positioning rod 21, so that the electric cylinder telescopically drives the positioning rod 21 to move. By driving the telescopic movement of the positioning rod 21 through the first electric cylinder 16, rapid and accurate positioning adjustment can be achieved. This design improves the automation and flexibility of the inspection, avoids errors in manual operation, and improves the stability and accuracy of the equipment. The electric drive makes the operation process simpler and improves work efficiency. The first electric cylinder 16 is provided in four sets. The four sets of first electric cylinders 16 provide stronger driving force and higher stability, ensuring sufficient support for the equipment during waterproof performance testing, allowing the positioning clamp 24 to remain stable under different component sizes. This not only enhances the clamping force but also reduces test deviations caused by equipment instability.

[0043] A water supply assembly is provided to supply spray water to the testing platform 1. The water supply assembly includes a fixed plate 5, a guide rail, a second drive component, and a spray head. The fixed plate 5 is installed at the second end of the workbench surface. The guide rail is installed on the top of the fixed plate 5 facing the first end of the workbench. The spray head is slidably installed on the guide rail via a second connector. The output end of the second drive component is fixedly connected to the second connector, so that the second drive component drives the spray head to slide along the guide rail, thereby changing the spray position of the spray head. The spray head is connected to the water receiving tank 2 via a water supply hose 4. The water supply hose 4 is equipped with a water pump 3 for supplying water from the water receiving tank 2 to the spray head.

[0044] Of course, this utility model does not impose any restrictions on the specific structure of the second driving component. Those skilled in the art can set it according to their needs. For example, the second driving component can be a motor, or it can be an electric cylinder, as long as the second driving component can drive the second connecting component to move on the guide rail. In this preferred embodiment, the second driving component is set as a multi-stage electric cylinder 6. The telescopic end of the multi-stage electric cylinder 6 is fixedly connected to the bushing, so that the multi-stage electric cylinder 6 telescopically drives the bushing to slide on the guide rail. By driving the sliding sleeve 8 to slide along the optical axis 7 through the multi-stage electric cylinder 6, the position of the nozzle 14 can be precisely adjusted to ensure that the sprayed water can cover all key parts of the prefabricated component. This design can be automatically adjusted in different scenarios to ensure that the spray position and angle during the testing process meet the preset requirements, thus improving the comprehensiveness of the waterproof performance test. There are four sets of the second electric cylinder 12. Setting four sets of the second electric cylinder 12 to drive the contact between the slotted block 17 and the prefabricated component makes the simulated water immersion scenario more accurate and stable. Through the design of synchronous operation, the second electric cylinder 12 can ensure that the simulated water level and environment are consistent during the immersion test, thereby enhancing the reliability and accuracy of the test.

[0045] The fixing plate 5 is also equipped with a water immersion mechanism for water immersion testing of the prefabricated components to be tested.

[0046] The positioning mechanism in the material installation assembly can slide on the worktable and is driven by the first drive component to adjust the position of the prefabricated component to be tested, adapting to components of different specifications and improving the flexibility of testing. The spray head in the water supply assembly can slide along the guide rail and is controlled by the second drive component to adjust the spray position, ensuring full coverage of the prefabricated component and improving the accuracy of testing. Through both spray testing and immersion testing, the waterproof performance of the prefabricated component is comprehensively tested, ensuring that the experimental data is closer to the actual working conditions. Furthermore, the spray head is designed as a movable structure, so that the waterproof performance of different areas can be tested, improving the comprehensiveness of testing. Through the automatic adjustment of the first and second drive components, precise positioning can be achieved, improving testing efficiency, reducing manual intervention, and improving the consistency and repeatability of testing.

[0047] In a preferred embodiment, the first connecting member is configured as a slide rail 19 structure. Of course, this invention does not impose any limitations on the specific structure of the first connecting member; those skilled in the art can set it according to their needs. For example, the first connecting member can also be a V-shaped slide rail 19 structure, or a rectangular slide rail 19 structure, as long as the worktable surface can slide stably on the testing table 1 via the slide rail 19 structure. The positioning mechanism includes a positioning plate 22, a positioning clamp 24, and a positioning rod 21. The positioning plate 22 is slidably connected to the slide rail 19 structure. The positioning clamp 24 is detachably mounted on the first end of the positioning plate 22 via bolts 25. The positioning plate 22 has multiple threaded holes to allow the positioning clamp 24 to be adjusted to different positions on the positioning plate 22. The second end of the positioning plate 22 is provided with a positioning rod 21, and a clamping space for clamping the prefabricated component to be tested is formed between the positioning rod 21 and the positioning clamp 24. By incorporating a slide rail 19, a sliding sleeve 20, a positioning rod 21, a positioning plate 22, a positioning hole 23, a positioning clamp 24, and a hand-tightening bolt 25, rapid clamping of precast components of different sizes can be achieved. The positioning clamp 24 can be adjusted according to the width of the component, and the position is fixed by the hand-tightening bolt 25, ensuring that the component remains stable and does not move during the inspection process. This improves the flexibility and firmness of clamping, reduces errors, and increases work efficiency.

[0048] Furthermore, the second connecting member includes a bushing and a connecting rod 9. The bushing is slidably fitted onto the guide rail, and the connecting rod 9 is fixedly installed at the bottom of the bushing. The connecting rod 9 is connected to the spray head via a spherical hinge structure, allowing the spray head to move and spray. The damping design of the ball head 11 and ball seat 10 makes the angle adjustment of the spray head 14 smoother and more stable. During spraying, the spray head 14 can flexibly adjust its angle without being affected by resistance, ensuring that the water flow can be sprayed evenly and accurately onto all parts of the precast component, simulating more complex rainfall conditions and enhancing the accuracy of the waterproof performance test. Of course, this utility model does not impose any restrictions on the connection method between the connecting rod 9 and the spray head. Those skilled in the art can set it according to their needs. For example, the connecting rod 9 and the spray head can be connected via a universal joint, or the connecting rod 9 and the spray head can be adjusted via an electric rotating shaft, as long as the spray head can be arbitrarily adjusted to the spray angle required by the operator.

[0049] Furthermore, a water-distributing chamber 13 is formed within the spray head. By providing the water-distributing chamber 13 within the spray assembly and adjusting the spray angle via the connecting rod 9 and the ball head 11, the water flow distribution becomes more uniform. This effectively improves the coverage of the sprayed water flow, ensuring that the water flow is uniformly sprayed during waterproof performance testing of the prefabricated components, thus enhancing the accuracy and reliability of the test. It should be noted that this invention does not impose any limitations on the specific structure of the water-distributing chamber 13. Those skilled in the art can design it according to their needs. For example, the water-distributing chamber 13 can be a spiral structure, or it can be a multi-chamber flow-guiding structure, as long as it ensures that the spray head can uniformly spray water through the water-distributing chamber 13.

[0050] Furthermore, the water immersion mechanism includes a slotted block 17 and a second electric cylinder 12. The slotted block 17 has a top opening and an opening near the prefabricated component to be tested. The top of the slotted block 17 is used to receive the spray water from the spray head. The second electric cylinder 12 is mounted on the fixed plate 5, and the output end of the second electric cylinder 12 is fixedly connected to the side of the slotted block 17 away from the prefabricated component to be tested, so that the second electric cylinder 12 can extend and retract to drive the slotted block 17 to contact or separate from the prefabricated component to be tested. Through the design of the first electric cylinder 16, the second electric cylinder 12, the side opening slot, and the concave sealing strip 18, a water immersion scenario can be simulated. The extension and retraction of the second electric cylinder 12 controls the movement of the slot, allowing it to make close contact with the side of the prefabricated component. The concave sealing strip 18 enhances the sealing effect, ensuring that water will not leak out during the test, simulating a more realistic water immersion environment and improving the accuracy of the waterproof performance test. It should be noted that this utility model does not impose any restrictions on the specific structure of the slotted block 17. Those skilled in the art can set it according to their needs. For example, a square slot can be opened in the slotted block 17, or a circular slot can be opened in the slotted block 17, as long as the slotted block 17 can be soaked in water in the slot.

[0051] Furthermore, a sealing strip is provided at the bottom of the side of the slotted block 17 that contacts the prefabricated component to be tested. Installing a sealing strip on the side of the slotted block 17 that contacts the prefabricated component effectively improves the sealing of the contact surface, preventing water leakage during simulated immersion testing. The design of the sealing strip ensures the stability and reliability of the immersion simulation process, improving the realism and accuracy of the waterproof performance test.

[0052] The technical solution of this utility model has been described in conjunction with the optional embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
