[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a vacuum water absorption rate testing device for building energy-saving materials, comprising a base 1, a vacuum chamber 13 fixedly connected to the base 1, a water inlet pipe 4, an air extraction pipe 5, and a drain pipe 6 fixedly connected to the vacuum tube, each equipped with a valve body, a top cover 3 on the top of the vacuum chamber 13, an adjustable clamping assembly below the top cover 3, and an adjustment assembly for height adjustment of the adjustable clamping assembly on the top cover 3, with support legs fixedly connected to the bottom of the base 1 on all four sides. A sealing strip is fixedly connected to the bottom of the top cover 3; the base 1 serves as the basic support structure of the device, providing a stable mounting platform for the vacuum chamber 13 and other components, ensuring the overall stable operation of the device during testing. The vacuum chamber 13 on the base 1 is the core space for water absorption rate testing, and its airtight design ensures a stable vacuum environment inside, providing reliable conditions for testing. The water inlet pipe 4 inside the vacuum chamber 13 is used to inject test water into the chamber, the air extraction pipe 5 connects to the vacuum pump to achieve vacuuming, and the drain pipe 6 is used to drain the water from the chamber after the test. These three components have clearly defined functions and together constitute the test's water circulation system. The valves in the water inlet pipe 4, air extraction pipe 5, and drain pipe 6 can control the opening and closing of each pipe, allowing operators to precisely control the water inlet, vacuuming, and draining processes according to the test procedures, ensuring the test is conducted in sequence. The top cover 3 of the vacuum chamber 13 can seal the chamber opening, and the sealing strip at the bottom of the top cover 3 enhances the sealing performance after closure, preventing vacuum leakage or water spillage and ensuring the stability of the vacuum state.

[0022] The adjustable clamping assembly below the top cover 3 is used to secure the building energy-saving material to be tested, preventing the material from shifting or floating during testing and ensuring test accuracy. The adjustable assembly can adjust the height of the adjustable clamping assembly to accommodate materials of different sizes, allowing the material to be fully immersed in water or the immersion depth to be adjusted as needed. The support legs at the bottom of the base 1 lift the equipment off the ground, reducing the impact of ground moisture or debris on the equipment, while also enhancing its stability.

[0023] In this embodiment, a vacuum pump and a water pump are installed on the outside of the base 1. The output end of the water pump is fixedly connected to the water inlet pipe 4, and the input end of the vacuum pump is fixedly connected to the air extraction pipe 5. A first cylinder 2 is fixedly connected to the base 1, and the output end of the first cylinder 2 is fixedly connected to the top cover 3. The vacuum pump outside the base 1 is connected to the vacuum chamber 13 through the air extraction pipe 5. After starting, it can quickly extract the air from the vacuum chamber 13 to create the required vacuum environment, thus creating conditions for the material to absorb water under vacuum and ensuring that the test results meet the relevant standards. The water pump delivers water to the vacuum chamber 13 through the water inlet pipe 4. Its stable water supply capacity ensures that the water level in the chamber can be accurately controlled to meet the water volume requirements of different tests.

[0024] The first cylinder 2 on the base 1 provides power for the opening and closing of the top cover 3. The extension and retraction of the cylinder drives the top cover 3 to move up and down, thus closing and opening the vacuum chamber 13. When test materials need to be placed or removed, the first cylinder 2 raises the top cover 3, opening the vacuum chamber 13. At the start of the test, the cylinder pushes the top cover 3 down, tightly closing it against the vacuum chamber 13, forming a sealed space with the sealing strip. This pneumatic control method is convenient to operate, provides uniform closing force, ensures the sealing of the vacuum chamber 13, avoids the sealing problems that may occur with manual closing, and improves the automation and reliability of the testing process.

[0025] In this embodiment, the adjustable clamping assembly includes a guide plate 9 and clamping plates 14 slidably connected to both sides of the guide plate 9. A sliding frame 10 is fixedly connected to the bottom of the clamping plate 14, and the sliding frame 10 is slidably connected to the outside of the guide plate 9. A threaded rod 11 is threadedly connected to the guide plate 9. An installation plate 8 is provided below the top cover 3, and the threaded rod 11 is rotatably connected to the installation plate 8. A guide rod 12 is fixedly connected to the bottom of the installation plate 8, and the guide rod 12 passes through the guide plate 9. The guide plate 9 in the adjustable clamping assembly provides a mounting and sliding base for the clamping plates 14. The clamping plates 14 on both sides slide on the guide plate 9 through the sliding frame 10 at the bottom, and the spacing can be adjusted according to the width of the test material to achieve the fixation of materials of different sizes. The threaded rod 11 threadedly connected to the guide plate 9 is rotatably connected to the installation plate 8. When the threaded rod 11 is rotated, the guide plate 9 will move up and down along the threaded rod 11, cooperating with the installation plate 8 to clamp or release the material.

[0026] The guide rod 12 at the bottom of the mounting plate 8 passes through the guide plate 9, providing guidance for the lifting and lowering of the guide plate 9 and preventing it from shifting or tilting during movement. This ensures that the clamping plate 14 can stably clamp the material. This structural design makes clamping operation flexible and convenient, adaptable to building energy-saving materials of different thicknesses, and ensures uniform force on the material during clamping. It avoids material damage or displacement during testing due to improper clamping, ensuring that the material remains stable throughout the testing process and guaranteeing the accuracy of the test results.

[0027] In this embodiment, the adjustment component is a second cylinder 7 fixedly connected to the top cover 3, and the output end of the second cylinder 7 is fixedly connected to the mounting plate 8. The second cylinder 7 of the adjustment component is fixed to the top cover 3, and its output end is connected to the mounting plate 8. The extension and retraction of the cylinder drives the mounting plate 8 and the adjustable clamping assembly to move up and down as a whole, thereby adjusting the height of the test material. During the test, the immersion depth of the material can be adjusted as needed using the second cylinder 7 to ensure that the material is completely immersed in the liquid, meeting the test requirements.

[0028] When the material needs to fully absorb water, the second cylinder 7 drives the mounting plate 8 and the material to move back and forth up and down within the vacuum chamber 13, ensuring that all parts of the material are evenly in contact with the water and preventing insufficient water absorption in certain areas from affecting the test results. This automated height adjustment method replaces traditional manual adjustment, which is not only easy to operate but also allows for precise control of the material's movement trajectory and amplitude, ensuring uniform water absorption and improving the reliability and consistency of test results. At the same time, the flexible adjustment capability of the second cylinder 7 enhances the equipment's adaptability to different types and sizes of materials, expanding its application range.

[0029] The usage method of this embodiment is as follows:

[0030] Slide the position of the clamping plate 14, then place the building energy-saving material to be tested on the clamping plate 14, then rotate the threaded rod 11 to drive the guide plate 9 to rise and fall, and clamp and fix the building energy-saving material through the clamping plate 14 and the mounting plate 8;

[0031] Then, the first cylinder 2 is started to drive the top cover 3 to move downward, and the top of the vacuum box 13 is sealed by the top cover 3. Then, the vacuum pump is used to evacuate the vacuum box 13 until the corresponding value is reached (measured by the vacuum pressure gauge installed in the vacuum box 13).

[0032] Then, the water is pumped into the vacuum chamber 13, and the second cylinder 7 is activated to push the mounting plate 8 downward, so that the mounting plate 8 can immerse the building energy-saving material to be tested in the water in the vacuum chamber 13. At the same time, the second cylinder 7 can also drive the mounting plate 8 to move up and down back and forth in the vacuum chamber 13, so that the building energy-saving material to be tested can fully absorb the water.

[0033] After the set time is reached, open the valve on the drain pipe 6 to extract the water from the vacuum chamber 13. Based on the mass of the specimen before and after the test, the vacuum water absorption rate of the building energy-saving material can be calculated according to the relevant calculation formula. The calculation formula is: Vacuum water absorption rate = (mass of specimen after water absorption - mass of specimen before test) / mass of specimen before test × 100%.

For example, they can refer to a fixed connection, a detachable connection, or an integral 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 based on the specific circumstances.
