Description

Technical Field

[0001] This utility model relates to the field of ALC wall panel sound insulation performance testing technology, specifically an ALC wall panel sound insulation performance on-site testing instrument. Background Technology

[0002] ALC wall panels are widely used in the construction industry due to their excellent properties such as lightweight, high strength, and thermal insulation. Sound insulation is a crucial performance indicator for ALC wall panels, directly impacting the comfort and functionality of a building.

[0003] Currently, the sound insulation performance of ALC wall panels is mostly tested in laboratories, which requires transporting wall panel samples to the laboratory. This process is cumbersome, and the laboratory testing environment differs from the actual on-site usage environment, resulting in test results that cannot accurately reflect the sound insulation performance of the wall panels after actual installation.

[0004] Furthermore, the sealing process relies heavily on manual operation, which is not only time-consuming but also leads to uneven pressure on the sealing plate, resulting in local gaps and sound leakage. This makes it impossible to provide an interference-free acoustic environment for testing, significantly reducing the reliability of the test data and making it difficult to control the sealing gap within an effective range.

[0005] Therefore, we proposed the ALC wall panel sound insulation performance field testing instrument to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an on-site testing instrument for the sound insulation performance of ALC wall panels, in order to solve the problems mentioned in the background art, such as the inability of existing testing instruments to accurately reflect the sound insulation performance of wall panels after actual installation, uneven pressure applied to the sealing plate during sealing, easy occurrence of local gaps leading to sound leakage, and inability to provide an interference-free acoustic environment for testing, resulting in inaccurate test data.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ALC wall panel sound insulation performance field testing instrument, comprising a base, a telescopic rod fixed to the top of the base, a support plate fixed to the top of the telescopic rod, a lifting assembly on the base, an installation frame fixed to the top of the support plate, a decibel meter installed on the side wall of the installation frame, a speaker installed inside the installation frame, multiple telescopic plates installed on the inner wall of the installation frame, and a clamping seal installed inside the installation frame. The clamping seal clamps the ALC wall panel body, and the clamping seal includes a sealing plate fixedly connected to the bottom surface of the telescopic plate.

[0008] Preferably, the lifting assembly includes a drive motor fixedly connected to the side wall of the base, a rotating rod fixedly connected to the output end of the drive motor, a bidirectional screw fixedly sleeved on the rotating rod, a slider threadedly connected to the bidirectional screw, a connecting rod hinged to the top of the slider, a connecting block hinged to the end of the connecting rod, and the connecting block fixedly connected to the support plate.

[0009] Preferably, the bidirectional screw has symmetrical screw grooves, the slider has an external thread that mates with the screw grooves, and there are two sliders that slide synchronously.

[0010] Preferably, a display is mounted on the surface of the mounting frame, and the speaker, decibel meter, and display are electrically connected.

[0011] Preferably, a support is fixed inside the mounting frame, and a dual-axis motor is fixedly connected inside the support. Both output ends of the dual-axis motor are fixedly connected to a drive shaft, and a gear is fixedly sleeved on the drive shaft. The telescopic plate is driven to move through a connecting rod and a connecting plate. A connecting rod is fixedly connected to the end of the connecting plate, and a toothed plate is fixed on the connecting rod. The toothed plate meshes with the gear.

[0012] Preferably, there are two gears symmetrically arranged, and two sets of toothed plates are symmetrically arranged about the gears. The toothed plates are symmetrically arranged, and the number of toothed plates corresponds to the number of telescopic plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By activating a dual-shaft motor to drive the meshing transmission of gears and toothed plates, two sets of toothed plates move the telescopic plates in opposite directions, ensuring a tight fit between the sealing plate and the edge of the ALC wall panel. This mechanical transmission method guarantees the smoothness and synchronicity of the telescopic plate movement, allowing for uniform pressure application to the sealing plate. This effectively avoids the localized gaps caused by uneven pressure during traditional manual sealing, completely blocking sound leakage. Compared to traditional manual sealing, this process not only saves installation time but also strictly controls the sealing gap within an effective range, providing an interference-free acoustic environment for on-site sound insulation testing. Furthermore, since the equipment can directly test the installed wall panels on-site, it avoids the result deviations caused by environmental differences in laboratory testing, ensuring from the source that the test data accurately reflects the actual sound insulation performance of the wall panels after installation, significantly improving data reliability.

[0014] 2. From clamping and sealing to parameter adjustment and data processing, the entire process is centrally controlled by an electronic control system. Each step is seamlessly connected, and operators can complete the series of processes with simple button operations without frequent manual intervention, reducing the probability of operational errors. At the same time, the continuity of the process avoids changes in the testing environment (such as loosening of the seal) caused by interruption of steps, ensuring the consistency and integrity of single test data, which is especially suitable for continuous testing scenarios of batch ALC wall panels.

[0015] 3. The lifting component design expands the lifting range of the support plate, adapting to ALC wall panel inspection needs from lower to higher positions. Whether the wall panel is installed at the bottom, middle, or top of the wall, the inspection equipment can be adjusted to the optimal inspection height, eliminating the need for additional auxiliary supports for wall panels of different heights. This significantly improves the versatility and flexibility of the equipment in complex construction sites. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-5 The ALC wall panel sound insulation performance field testing instrument includes a base 1, a telescopic rod 2 fixed to the top of the base 1, a support plate 3 fixed to the top of the telescopic rod 2, a mounting frame 5 fixed to the top of the support plate 3, a decibel meter 6 mounted on the side wall of the mounting frame 5, a speaker 7 mounted inside the mounting frame 5, multiple telescopic plates 8 mounted on the inner wall of the mounting frame 5, and a clamping seal 10 mounted inside the mounting frame 5. The clamping seal 10 clamps the ALC wall panel body 9, and the clamping seal 10 includes a sealing plate 108 fixedly connected to the bottom surface of the telescopic plate 8. The sealing plate 108 is made of rubber, which is soft and has good sealing properties, and can fit tightly against the surface of the ALC wall panel to prevent sound leakage from gaps and affecting the test results.

[0020] A display 51 is mounted on the surface of the mounting frame 5, which can clearly display the detected sound pressure level, frequency, and other data. It also has data storage and export functions for convenient analysis and organization of the test data. The speaker 7, decibel meter 6, and display 51 are electrically connected. The speaker 7 is a full-range speaker, capable of emitting sounds of different frequencies and intensities to meet the sound source requirements for sound insulation performance testing. The power of the speaker 7 is set according to the testing environment requirements. The decibel meter 6 can detect sound intensity in real time; its sensor uses a high-sensitivity microphone to accurately capture sound signals of different frequencies.

[0021] A support 101 is fixed inside the mounting frame 5. A dual-axis motor 102 is fixedly connected inside the support 101. A drive shaft 103 is fixedly connected to both output ends of the dual-axis motor 102. A gear 104 is fixedly sleeved on the drive shaft 103. The telescopic plate 8 is driven to move by the connecting rod 106 and the connecting plate 107. A connecting rod 106 is fixedly connected to the end of the connecting plate 107. A toothed plate 105 is fixed on the connecting rod 106. The toothed plate 105 meshes with the gear 104.

[0022] Two gears 104 are symmetrically arranged, and two sets of toothed plates 105 are symmetrically arranged about the gears 104. The toothed plates 105 are symmetrically arranged, and the number of toothed plates 105 corresponds to the number of telescopic plates 8.

[0023] Specifically, the working principle of the ALC wall panel sound insulation performance field tester is to evaluate the sound insulation performance of the wall panel by detecting the degree of sound attenuation after it passes through the ALC wall panel.

[0024] Before testing, the support plate 3 is adjusted to a suitable height by adjusting the length of the telescopic rod 2 according to the size of the ALC wall panel and the testing requirements. Then, the ALC wall panel body 9 is placed in the clamping seal 10 in the mounting frame 5, and the dual-axis motor 102 is started. The output ends on both sides of the dual-axis motor 102 drive the transmission shaft 103 to rotate, and the gear 104 on the transmission shaft 103 rotates accordingly. Since the gear 104 meshes with the toothed plate 105 and the toothed plate 105 is symmetrically arranged, the two sets of toothed plates 105 will move in opposite directions under the drive of the gear 104, driving the telescopic plate 8 to move through the connecting rod 106 and the connecting plate 107.

[0025] When the telescopic plate 8 moves, the sealing plate 108 on its bottom surface will gradually fit tightly against the edge of the ALC wall panel, thereby clamping and sealing the ALC wall panel, preventing sound from leaking from the gap between the wall panel and the mounting frame 5, and ensuring the airtightness of the testing environment.

[0026] After sealing, speaker 7 emits a sound at a set frequency and intensity. Part of the sound is blocked by the ALC wall panel, while the rest passes through it. The decibel meter 6 measures the sound pressure level on both sides of the wall panel, with one side being the sound source side (where speaker 7 is located) and the other side being the receiving side (where decibel meter 6 is located). The detected sound pressure level data is transmitted to the display 51 in real time. The display 51 processes and displays the data. By calculating the difference in sound pressure level between the sound source side and the receiving side, the sound insulation of the ALC wall panel can be obtained, thereby evaluating its sound insulation performance.

[0027] During the testing process, if it is necessary to adjust the testing parameters, these can be set through the operation interface on the display 51, such as changing the frequency and intensity of the sound emitted by the speaker 7, to adapt to different testing needs. After the testing is completed, the testing data can be stored in the memory of the display 51 or exported through the data interface for further analysis.

[0028] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-2 The base 1 is provided with a lifting assembly 4. The lifting assembly 4 includes a drive motor 41 fixedly connected to the side wall of the base 1. The output end of the drive motor 41 is fixedly connected to a rotating rod 42. A bidirectional screw 43 is fixedly sleeved on the rotating rod 42. A slider 44 is threadedly connected to the bidirectional screw 43. A connecting rod 45 is hinged to the top of the slider 44. A connecting block 46 is hinged to the end of the connecting rod 45. The connecting block 46 is fixedly connected to the support plate 3.

[0029] The bidirectional screw 43 has symmetrical threaded grooves, and the slider 44 has an external thread that mates with the threaded grooves. There are two sliders 44, and the two sliders 44 slide synchronously. The threaded grooves on both sides rotate in opposite directions, which can realize the synchronous opposite or opposite sliding of the two sliders 44.

[0030] Specifically, when the height of the detector needs to be adjusted according to the installation position of the ALC wall panel, the drive motor 41 drives the bidirectional screw 43 to rotate. The screw and the slider 44 are connected by a thread to convert the rotational motion into the linear motion of the slider 44. The support plate 3 is then raised and lowered through the transmission of the connecting rod 45.

[0031] When the height of the support plate 3 needs to be adjusted, the electronic control system sends a command to the drive motor 41. The drive motor 41 starts and drives the rotating rod 42 to rotate. The rotating rod 42 transmits power to the bidirectional screw 43 through a coupling, causing the bidirectional screw 43 to rotate synchronously. Because the bidirectional screw 43 has symmetrical and oppositely helical grooves, and the external threads in the two sliders 44 respectively mate with the grooves on both sides, when the screw rotates, the two sliders 44 will slide synchronously in opposite directions along the screw (i.e., one slider 44 moves towards the motor, and the other moves away from the motor).

[0032] As the slider 44 slides, the connecting rod 45 hinged to the slider 44 will change angle. The top of the connecting rod 45 pushes or pulls the support plate 3 through the connecting block 46. When the two sliders 44 slide towards each other, the included angle between the connecting rods 45 decreases, and the connecting rod 45 pushes the connecting block 46 and the support plate 3 upward, causing the support plate 3 to rise. When the two sliders 44 slide in opposite directions, the included angle between the connecting rods 45 increases, and the connecting rod 45 pulls the connecting block 46 and the support plate 3, causing the support plate 3 to fall. This allows the height to be adjusted to a suitable level as needed, so as to facilitate the sound insulation performance testing of ALC wall panels at different heights.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
