Description

Technical Field

[0001] This utility model relates to the field of acoustic materials technology, specifically to an acoustic materials testing device. Background Technology

[0002] Acoustic materials are mainly divided into two categories: sound-absorbing materials and sound-insulating and vibration-damping materials. Common sound-absorbing materials include wooden sound-absorbing panels, fabric-covered sound-absorbing panels, and polyester fiber sound-absorbing panels. Wooden sound-absorbing panels are further divided into grooved wood sound-absorbing panels and perforated wood sound-absorbing panels.

[0003] For example, the authorization announcement number "CN217304744U" is titled "A Hardness Testing Device for Acoustic Materials." Through the arrangement of the transmission and testing components, different locations of the same sample can be compressed with varying pressure values. This allows for the measurement of the material's hardness and clearly demonstrates its resistance to different pressures. However, existing hardness testing devices for acoustic materials are problematic because most acoustic materials are used in building construction and installed on building walls. These materials require a certain level of fire resistance. Conventionally, in building material testing, acoustic materials are manually tested by burning the surface with a lighter. However, the flame produced by a lighter is relatively small and cannot simulate a real fire, thus failing to accurately test the fire resistance of acoustic materials. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing hardness testing devices for acoustic materials cannot test the fire resistance of acoustic materials, and to propose an acoustic material testing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an acoustic material testing device, including a base, uprights, and a top plate. Multiple uprights are fixedly installed on the upper end of the base, and the top plate is fixedly installed on the top of the multiple uprights. A support plate is fixedly installed on the upper part of the base. An acoustic material fire resistance testing structure is provided on the upper part of the base. An acoustic material support and positioning structure is provided below the top plate. An acoustic material pressure resistance testing structure is provided on the inner side of the top plate.

[0007] Preferably, the acoustic material fire resistance testing structure includes a gas cylinder and an ignition platform. The gas cylinder is movably mounted on the ground on the side away from the base. One end of the gas cylinder is fixedly connected to a gas supply pipe, and a regulating valve is fixedly installed on the outside of the gas supply pipe. The ignition platform is fixedly installed on the top of the support plate, and multiple nozzles are fixedly installed above the ignition platform. Two wind shields are fixedly installed above the support plate.

[0008] Preferably, the inner sides of the two windshields are arranged opposite to the ignition platform, and the end of the gas supply pipe is connected to the nozzle.

[0009] Preferably, the acoustic material support and positioning structure includes transverse grooves and connecting blocks. Two transverse grooves are fixedly formed at the front end of the top plate. Slider blocks are slidably connected to the inner sides of the two transverse grooves. Adjustment knobs are fixedly installed on the outer sides of the two sliders. Connecting blocks are fixedly connected to the bottom ends of the two sliders. Hydraulic cylinders are fixedly installed at the lower ends of the two connecting blocks. Placement grooves are fixedly installed at the lower ends of the two hydraulic cylinders.

[0010] Preferably, an acoustic material plate is movably placed inside the two placement slots, and the lower end of the acoustic material plate is arranged opposite to a plurality of nozzles.

[0011] Preferably, the acoustic material pressure resistance test structure includes a pressure detector and a vertical column. The vertical column is fixedly installed on the lower end of the inner wall of the top plate, and a pressure sensor is fixedly connected to the bottom end of the vertical column. The pressure detector is fixedly installed above the top plate, and the pressure detector is electrically connected to the pressure sensor through a wire.

[0012] The acoustic material testing device proposed in this utility model has the following advantages: by unscrewing the regulating valve, the stored liquefied gas is sprayed out along the gas pipeline to the nozzle, and then the gas sprayed out of the nozzle is ignited to form a relatively large flame. The flame is used to burn the bottom surface of the acoustic material plate. The wind shield surrounds the ignition platform in the middle on both sides, which can make the flame more concentrated and the heating speed faster. Then, the operator can close the regulating valve after the set time, and the flame will be extinguished. At this time, the degree of damage to the bottom of the acoustic material plate by burning is observed to judge the fire resistance performance of the material. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, an acoustic material testing device includes a base 1, uprights 2, and a top plate 3. Multiple uprights 2 are fixedly installed on the upper end of the base 1. The top plate 3 is formed by welding multiple uprights 2 to the base 1. The base 1, uprights 2, and top plate 3 are all made of high-strength, non-deformable aluminum alloy material. The top plate 3 is fixedly installed on the top of multiple uprights 2. A support plate 6 is fixedly installed on the upper part of the base 1. An acoustic material fire resistance testing structure 5 is provided on the upper part of the base 1. An acoustic material support and positioning structure 7 is provided on the lower part of the top plate 3. An acoustic material pressure resistance testing structure 8 is provided on the inner side of the top plate 3.

[0023] The acoustic material fire resistance testing structure 5 includes a gas cylinder 51 and an ignition platform 54. The gas cylinder 51 is movably mounted on the ground away from the base 1. The gas cylinder 51 is filled with liquefied gas. After the operator places a piece of acoustic material 4 to be tested horizontally inside the placement slot 76 below the hydraulic cylinder 75, the hydraulic cylinder 75 pushes the acoustic material 4 downwards towards the ignition platform 54. One end of the gas cylinder 51 is fixedly connected to a gas supply pipe 52, and a regulating valve 53 is fixedly installed on the outside of the gas supply pipe 52. The ignition platform 54 is fixedly installed on the top of the support plate 6, and multiple nozzles 55 are fixedly installed above the ignition platform 54. Then, the regulating valve 53 is opened to release the gas. The stored liquefied gas is sprayed out at the nozzle 55 along the gas pipeline 52, and then the gas sprayed out by the nozzle 55 is ignited to form a relatively large flame. The flame is used to burn the bottom surface of the acoustic material plate 4. Two wind shields 56 are fixedly installed on the top of the support plate 6. The wind shields 56 surround the ignition platform 54 in the middle on both sides, so that the flame can be more concentrated and the heating speed is faster. Then, the staff can close the regulating valve 53 at the set time, and the flame will be extinguished. At this time, the degree of damage to the bottom of the acoustic material plate 4 by burning is observed to judge the fire resistance of the material. The inner side of the two wind shields 56 is set opposite to the ignition platform 54, and the end of the gas pipeline 52 is connected to the nozzle 55.

[0024] The gas cylinder 51 is filled with liquefied gas. After the operator places a piece of acoustic material plate 4 to be tested horizontally in the placement slot 76 below the hydraulic cylinder 75, the hydraulic cylinder 75 pushes the acoustic material plate 4 downwards towards the ignition platform 54. Then, the regulating valve 53 is turned on to spray the stored liquefied gas along the gas pipeline 52 at the nozzle 55. The gas sprayed from the nozzle 55 is then ignited to form a relatively large flame. The flame is used to burn the bottom surface of the acoustic material plate 4. The wind shield 56 surrounds the ignition platform 54 in the middle on both sides, which can make the flame more concentrated and the heating speed faster. Then, the operator can close the regulating valve 53 after the set time, and the flame will go out. At this time, the degree of damage to the bottom of the acoustic material plate 4 by burning is observed to judge the fire resistance performance of the material.

[0025] The acoustic material support and positioning structure 7 includes transverse grooves 71 and connecting blocks 74. Two transverse grooves 71 are fixedly opened at the front end of the top plate 3. The transverse grooves 71 allow the internal sliders 72 to be manually adjusted laterally by gripping the adjustment knob 73. This can drive the lower connecting block 74 to change the distance between the hydraulic cylinders 75. The inner sides of the two transverse grooves 71 are slidably connected to the sliders 72. The outer sides of the two sliders 72 are fixedly installed with the adjustment knob 73. The bottom ends of the two sliders 72 are fixedly connected to the connecting blocks 74. The lower ends of the two connecting blocks 74 are fixedly installed with the hydraulic cylinders 75. Two L-shaped placement grooves 76 are suspended below the hydraulic cylinders 75. The two ends of the acoustic material plate 4 can be overlapped and placed inside the placement grooves 76. The distance between the two placement grooves 76 can also be adjusted to facilitate the fixing of acoustic materials of different sizes. The lower ends of the two hydraulic cylinders 75 are fixedly installed with the placement grooves 76. The acoustic material plate 4 is movably placed inside the two placement grooves 76. The lower end of the acoustic material plate 4 is opposite to multiple nozzles 55.

[0026] Working principle:

[0027] The acoustic material testing device is used to conduct compressive and fire resistance tests on acoustic materials used in building engineering. The acoustic material can be a polyester fiber sound-absorbing board.

[0028] Fire resistance testing of acoustic material testing equipment:

[0029] The gas cylinder 51 is filled with liquefied gas. After the operator places a piece of acoustic material plate 4 to be tested horizontally in the placement slot 76 under the hydraulic cylinder 75, the hydraulic cylinder 75 pushes the acoustic material plate 4 downward toward the ignition platform 54. Then, the regulating valve 53 is turned on to spray the stored liquefied gas along the gas pipeline 52 at the nozzle 55. The gas sprayed from the nozzle 55 is then ignited to form a relatively large flame. The flame is used to burn the bottom surface of the acoustic material plate 4. The wind shield 56 surrounds the ignition platform 54 in the middle on both sides, which can make the flame more concentrated and the heating speed faster. Then, the operator can close the regulating valve 53 after the set time, and the flame will be extinguished. At this time, the degree of damage to the bottom of the acoustic material plate 4 by burning is observed to judge the fire resistance performance of the material.

[0030] Acoustic material placement structure of the acoustic material testing device:

[0031] The transverse groove 71 allows the internal slider 72 to be manually adjusted laterally by gripping the adjustment knob 73. This, in turn, drives the lower connecting block 74 to change the distance between the hydraulic cylinders 75. The inner sides of the two transverse grooves 71 are slidably connected to the sliders 72, and the outer sides of the two sliders 72 are fixedly installed with the adjustment knob 73. The bottom ends of the two sliders 72 are fixedly connected to the connecting blocks 74, and the lower ends of the two connecting blocks 74 are fixedly installed with the hydraulic cylinders 75. Two L-shaped placement grooves 76 are suspended below the hydraulic cylinders 75. The two ends of the acoustic material plate 4 can be overlapped inside the placement grooves 76 for placement. The distance between the two placement grooves 76 can also be adjusted to facilitate the fixing of acoustic materials of different sizes.

[0032] Example 2:

[0033] Please see Figure 1-6In this embodiment, an acoustic material testing device includes an acoustic material pressure resistance testing structure 8 comprising a pressure detector 81 and a vertical column 82. The vertical column 82 is fixedly installed on the lower end of the inner wall of the top plate 3, and a pressure sensor 83 is fixedly connected to the bottom end of the vertical column 82. The pressure detector 81 is fixedly installed above the top plate 3. The pressure detector 81 is a prior art model BL-3000 intelligent pressure testing instrument. Together with the pressure sensor 83, it can detect the pressure at the lowest point of the vertical column 82. During the acoustic material testing process, the acoustic material plate 4 is placed under the hydraulic cylinder 75. The acoustic material plate 4 is placed inside the slot 76 at the end, and then the power supply is connected to start the hydraulic cylinder 75. The hydraulic cylinder 75 will rise upward until the top surface of the acoustic material plate 4 is pressed against the lower end of the vertical column 82. As the hydraulic cylinder 75 continuously drives the acoustic material plate 4 to press under the vertical column 82, the acoustic material plate 4 will be deformed and bent under the force. The pressure value will also be displayed on the pressure detector 81. When the acoustic material plate 4 can no longer withstand the pressure and is completely squeezed, deformed and broken, the data on the current pressure detector 81 can be read as the pressure resistance test result of the acoustic material. The pressure detector 81 is electrically connected to the pressure sensor 83 through the wire.

[0034] Working principle:

[0035] The vertical column 82 is fixedly installed on the lower end of the inner wall of the top plate 3. The pressure detector 81 is a BL-3000 intelligent pressure tester, which, together with the pressure sensor 83, can detect the pressure on the lower end of the vertical column 82. During the acoustic material test, the acoustic material plate 4 is placed inside the placement groove 76 at the lower end of the hydraulic cylinder 75. Then, the power is connected and the hydraulic cylinder 75 is started. The hydraulic cylinder 75 will rise until the top surface of the acoustic material plate 4 is against the lower end of the vertical column 82. As the hydraulic cylinder 75 continuously moves the acoustic material plate 4 to press under the vertical column 82, the acoustic material plate 4 will deform and bend under the force. The pressure detector 81 will also display the pressure value. When the acoustic material plate 4 can no longer withstand the pressure and is completely squeezed, deformed and broken, the data on the current pressure detector 81 can be read as the pressure resistance test result of the acoustic material.
