Description

Technical Field

[0001] The present invention relates to the technical field of building detection, and in particular to a device and method for detecting building sound insulation performance. Background Art

[0002] Existing methods for testing sound insulation between floors primarily rely on manually creating noise on the upper floor and simultaneously measuring the noise level using sound pickup devices on the lower floor. Due to the large floor plan, this method struggles to accurately detect small areas, leading to inaccurate results. This method is particularly ineffective for floors with high sound insulation requirements. Furthermore, existing detection devices rely on manual adjustment and handling, increasing testing costs. Summary of the Invention

[0003] To solve the above problems, the present invention aims to propose a device and method for detecting the sound insulation performance of buildings. By setting up a displacement noise reduction module, an all-round noise reduction effect is achieved, and the execution device intermittently knocks on the ground during the execution process to increase the noise propagation efficiency to meet the high-frequency noise reduction needs, thereby solving the problem of poor detection effect of existing detection devices.

[0007] Furthermore, the deflection mechanism includes a top seat, the top of the top seat is fixedly connected to the bottom of the rail plate one, the top seat supports the rail plate one, a double-axis camel machine is provided at the bottom of the top seat, the middle outer wall of the double-axis camel machine is rotatably connected to a connecting shaft, and the other end of the connecting shaft is rotatably connected to the middle of the top seat, both ends of the top seat are rotatably connected to a drive shaft, and the other end of the drive shaft is fixedly connected to the output end corresponding to the double-axis camel machine.

[0008] Furthermore, the noise reduction mechanism includes a base, a limit groove, a hollow drum, a motor 1, a positioning shaft, a spring and a pick; the top of the base is fixedly connected to the bottom of the double-axis camel machine, the base supports the double-axis camel machine, and limit grooves are provided on both side walls of the base. The inner walls on both sides of the front end of the base are rotatably connected to the hollow drum, and the outer wall of the base is fixedly installed with a motor 1, and the output end of the motor 1 is fixedly connected to the end wall of the hollow drum; the inner walls on both sides of the hollow drum are rotatably connected to the positioning shafts, and the positioning shafts pass through the right side of the hollow drum. On the side, a spring piece is fixedly installed on the positioning shaft inside the hollow drum. There are multiple groups of spring pieces, which are distributed on the positioning shaft in an open and close ellipsoidal shape. The spring piece is made of elastic metal material. When the pick contacts the spring piece, it can cause it to deform slightly and vibrate and make a sound. The end wall of the positioning shaft outside the hollow drum is engaged with the limit groove. The limit groove limits the positioning shaft so that it cannot rotate with the rotation of the hollow drum. A pick is fixedly installed on the inner wall of the hollow drum, and the pick contacts the spring piece.

[0009] Furthermore, the inner walls at both ends of the top of the support shell are rotatably connected to the main shaft, the support shell supports the main shaft, and the style of the main shaft is designed as a crank shaft, and the inner walls at both ends of the bottom of the support shell are fixedly installed with limit shells, and a crank-connecting rod mechanism is provided inside the two sets of limit shells.

[0011] In order to achieve the above object, the present invention also provides a detection method of the building sound insulation performance detection device as described above, comprising the following steps: S1: Mark out the test areas on the ground of the building to be tested so that the test areas are distributed in a "well" shape, and label the test areas in sequence, such as "A, B, C...". By adjusting the dual-axis camel machine, the four sets of hollow rotating drums at the bottom of the device are in contact with the ground, and the device is placed in each test area in sequence to perform the test work; S2: When performing sound insulation testing on each area to be tested, a sound collector is placed in the bottom space of the area to be tested to collect noise, and the driving motor 1 drives the hollow drum to rotate, so that the device moves in the area to be tested.

Thereafter, the double-axis camel is driven to drive the two sets of driving shafts to deflect upward, thereby driving the base to move upward, so that the hollow drum is separated from the ground. At this time, the two sets of support frames are in contact with the ground, thereby supporting the entire device. At the same time, the two sets of electric telescopic rods are driven in the opposite direction to drive the track plate 1 to reset, thereby transporting the four sets of hollow drums at the bottom of the device to the adjacent position. Thereafter, the double-axis camel is reversed to make the hollow drum contact the ground again, and the motor 1 is driven to move the device back. Repeating the above operation can make the device move in the entire area to be tested. S3: When the device moves in the test area, the hollow drum can drive the paddle to rotate. Under the limiting effect of the limit slot, the positioning shaft and the spring cannot rotate. At this time, the paddle can periodically poke each spring, causing it to vibrate and make sound. The volume of the noise emitted can be collected by the sound receiver to determine the sound insulation effect of the building. S4: When the thickness of the building to be tested is relatively thick, that is, the sound insulation performance required of the building is relatively strong, while driving the device to move, the second driving motor drives the main shaft to rotate, thereby driving the two sets of crank-connecting rod mechanisms to work, so that the knocking hammer at the bottom of the crank-connecting rod mechanism can reciprocate, so that the knocking hammer can continuously knock on the ground while the device is moving. At this time, the sound volume of the knocking noise can be collected through the sound receiver to judge the sound insulation effect of the building.

[0012] Beneficial effect: The present invention sets a displacement noise suppression module so that the device can move on the ground and generate noise during the movement, thereby achieving an all-round noise suppression effect. At the same time, for certain floors that require strong sound insulation performance, the execution device can use a hammer to intermittently hammer the ground during the movement, so that the noise can be conducted through contact to increase the transmission efficiency, thereby meeting the high-frequency noise suppression effect and solving the problem of poor detection effect of the existing building sound insulation performance detection device.

Both ends of the top seat 111 are rotatably connected to a drive shaft 114, and the other end of the drive shaft 114 is fixedly connected to the output end corresponding to the double-axis camel machine 112.

[0021] In this embodiment, after the device moves from the head end to the end end in the area to be measured, the two sets of electric telescopic rods are driven to make the track plate 2 slide on the track plate 1, thereby transporting the execution device to an adjacent position. Thereafter, the double-axis camel machine is driven to drive the two sets of driving shafts to deflect upward, thereby driving the base to move upward, so that the hollow drum is separated from the ground. At this time, the two sets of support frames are in contact with the ground, thereby supporting the entire device. At the same time, the two sets of electric telescopic rods are driven in the opposite direction to drive the track plate 1 to reset, thereby transporting the four sets of hollow drums at the bottom of the device to an adjacent position. Thereafter, the double-axis camel machine is reversed to make the hollow drum contact the ground again, and the motor 1 is driven to move the device back. Repeating the above operations can make the device move in the entire area to be measured.

There are multiple groups of spring pieces 126, which are distributed on the positioning shaft 125 in an open and close ellipsoidal shape. The spring piece 126 is made of elastic metal material. When the paddle 127 contacts the spring piece 126, it can cause it to deform slightly and vibrate and make a sound. The end wall of the positioning shaft 125 outside the hollow rotating cylinder 123 is engaged with the limiting groove 122. The limiting groove 122 limits the positioning shaft 125 so that it cannot rotate with the rotation of the hollow rotating cylinder 123. The paddle 127 is fixedly installed on the inner wall of the hollow rotating cylinder 123, and the paddle 127 contacts the spring piece 126.

[0023] In this embodiment, when performing sound insulation testing on each area to be tested, a sound collector is placed in the bottom space of the area to be tested to collect noise, and a driving motor drives the hollow drum to rotate, so that the device moves in the area to be tested.

[0024] When the device moves in the area to be tested, the hollow drum can drive the paddle to rotate, and under the limiting action of the limit groove, the positioning shaft and the spring cannot rotate. At this time, the paddle can periodically poke each spring, causing it to vibrate and make sound. The volume of the noise emitted can be collected through the sound receiver to determine the sound insulation effect of the building.

[0025] In a specific embodiment, the inner walls at both ends of the top of the support shell 210 are rotatably connected to the main shaft 211, the support shell 210 supports the main shaft 211, and the style of the main shaft 211 is designed as a crank shaft. The inner walls at both ends of the bottom of the support shell 210 are fixedly installed with limit shells 212. The two sets of limit shells 212 are internally provided with a crank-connecting rod mechanism 213. The crank-connecting rod mechanism 213 consists of a push rod and a sleeve, wherein the push rod is rotatably connected to the crank shaft, and the other end of the push rod is rotatably connected to the sleeve. The limiting shell 212 can limit the sleeve so that it can only perform reciprocating motion, and the input end of the crank-connecting rod mechanism 213 is fixedly connected to the main shaft 211.

The output end of the crank-connecting rod mechanism 213 is fixedly installed with a striking hammer 215, which is fixedly connected to the end of the sleeve and slides through the bottom of the support shell 210.

[0026] In this embodiment, when the thickness of the building to be tested is relatively thick, that is, the sound insulation performance required of the building is relatively strong, while driving the device to move, the driving motor 2 drives the main shaft to rotate, thereby driving the two sets of crank-connecting rod mechanisms to work, so that the knocking hammer at the bottom of the crank-connecting rod mechanism can reciprocate, so that the knocking hammer can continuously knock on the ground while the device is moving. At this time, the sound volume of the knocking noise can be collected by the sound receiver, thereby judging the sound insulation effect of the building.

[0027] In a specific example, a support frame 221 is fixedly installed on the outer wall of the side beam frame 220, and the side beam frame 220 supports the support frame 221, and the bottom of the support frame 221 can contact the ground.

[0028] To sum up, this embodiment sets up a noise suppression mechanism, places a sound collector in the bottom space of the area to be tested to collect noise, drives the hollow drum to rotate by a driving motor, and makes the device move in the area to be tested. The hollow drum can drive the paddle to rotate, and under the limiting action of the limiting groove, the positioning shaft and the spring cannot rotate. At this time, the paddle can periodically poke each spring to make it vibrate and make sound. The volume of the noise emitted can be collected by the sound collector, thereby judging the sound insulation effect of the building.

[0029] By setting up an execution device, when the thickness of the building to be tested is relatively thick, that is, the sound insulation performance required of the building is relatively strong, while driving the device to move, the second driving motor drives the main shaft to rotate, thereby driving the two sets of crank-connecting rod mechanisms to work, so that the knocking hammer at the bottom of the crank-connecting rod mechanism can reciprocate, so that the knocking hammer can continuously knock on the ground while the device is moving. At this time, the sound volume of the knocking noise can be collected through the sound receiver, so as to judge the sound insulation effect of the building.

[0030] By setting up a deflection mechanism, when the device moves from the head end to the end end in the area to be tested, the two sets of electric telescopic rods are driven to make the track plate 2 slide on the track plate 1, thereby transporting the actuator to the adjacent position. Thereafter, the double-axis camel machine is driven to drive the two sets of driving shafts to deflect upward, thereby driving the base to move upward, so that the hollow drum is separated from the ground. At this time, the two sets of support frames are in contact with the ground, thereby supporting the entire device. At the same time, the two sets of electric telescopic rods are driven in the opposite direction to drive the track plate 1 to reset, thereby transporting the four sets of hollow drums at the bottom of the device to the adjacent position. Thereafter, the double-axis camel machine is reversed to make the hollow drum contact with the ground again, and the motor 1 is driven to make the device move back. Repeating the above operations can make the device move in the entire area to be tested.

[0031] Example 2 To achieve the above objectives, this embodiment further provides a method for detecting a building sound insulation performance detection device, comprising the following steps: S1: Mark out the test areas on the ground of the building to be tested so that the test areas are distributed in a "well" shape, and label the test areas in sequence as "A, B, C...". By adjusting the dual-axis camel 112, the four sets of hollow rotating drums 123 at the bottom of the device are in contact with the ground, and the device is placed in each test area in sequence to perform the test work; S2: When performing sound insulation testing on each area to be tested, a sound collector is placed in the bottom space of the area to be tested to collect noise, and the driving motor 124 drives the hollow drum 123 to rotate, so that the device moves in the area to be tested. When the device moves from the head end to the end in the area to be tested, the two sets of electric telescopic rods 150 are driven to make the track plate 2 140 slide on the track plate 1 130, thereby transporting the execution device 200 to the adjacent position. Thereafter, the dual-axis camel 112 is driven to drive the two sets of drive shafts 114 to deflect upward, thereby The base 121 is driven to move upward, so that the hollow rotating cylinder 123 is separated from the ground. At this time, the two sets of support frames 221 are in contact with the ground, thereby supporting the entire device. At the same time, the two sets of electric telescopic rods 150 are driven in the opposite direction, driving the track plate 130 to reset, thereby transporting the four sets of hollow rotating cylinders 123 at the bottom of the device to an adjacent position. Thereafter, the dual-axis camel 112 is reversed to make the hollow rotating cylinder 123 contact the ground again, and the motor 1 124 is driven to move the device back. Repeating the above operation can make the device move throughout the entire test area; S3: When the device moves within the test area, the hollow rotating cylinder 123 can drive the paddle 127 to rotate. However, under the limiting action of the limiting groove 122, the positioning shaft 125 and the spring 126 cannot rotate. At this time, the paddle 127 can periodically paddle each spring 126, causing it to vibrate and make a sound. The volume of the noise emitted can be collected by the sound receiver to determine the sound insulation effect of the building. S4: When the thickness of the building to be tested is relatively thick, that is, the sound insulation performance required of the building is relatively strong, while driving the device to move, the driving motor 214 drives the main shaft 211 to rotate, thereby driving the two sets of crank-connecting rod mechanisms 213 to work, so that the knocking hammer 215 at the bottom of the crank-connecting rod mechanism 213 can reciprocate, so that the knocking hammer 215 can continuously knock on the ground while the device is moving. At this time, the sound volume of the knocking noise can be collected by the sound receiver, so as to judge the sound insulation effect of the building.

The limit shell ( 212) can limit the sleeve so that it can only perform reciprocating motion, and the input end of the crank-connecting rod mechanism (213) is fixedly connected to the main shaft (211), the outer wall of the support shell (210) is fixedly installed with a second motor (214), and the output end of the second motor (214) is fixedly connected to the end wall of the main shaft (211), and the output end of the crank-connecting rod mechanism (213) is fixedly installed with a striking hammer (215), the striking hammer (215) is fixedly connected to the end of the sleeve, and the striking hammer (215) slides through the bottom of the support shell (210).

7. The building sound insulation performance detection device according to claim 2, characterized in that: A support frame (221) is fixedly mounted on the outer wall of the side beam frame (220), the side beam frame (220) supports the support frame (221), and the bottom of the support frame (221) can contact the ground. When the support frame (221) contacts the ground, it can support the execution device (200), so that the displacement noise suppression module (100) completes the column switching operation.

8. A method for detecting the building sound insulation performance detection device according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1: Marking the test areas on the ground of the building to be tested so that the test areas are distributed in a "well" shape, and sequentially marking the test areas as "A, B, C...", adjusting the double-axis camel machine (112) so that the four sets of hollow rotating drums (123) at the bottom of the device are in contact with the ground, and sequentially placing the device in each test area to perform the test work; S2: When performing sound insulation testing on each area to be tested, a sound collector is placed in the bottom space of the area to be tested to collect noise, and the driving motor 1 (124) drives the hollow drum (123) to rotate, so that the device moves in the area to be tested. When the device moves from the head end to the end end in the area to be tested, the two sets of electric telescopic rods (150) are driven to make the track plate 2 (140) slide on the track plate 1 (130), thereby transporting the execution device (200) to the adjacent position, and then driving the double-axis camel machine (112) to drive the two sets of drive shafts (114) to deflect upward, thereby bringing The movable base (121) moves upward, causing the hollow rotating drum (123) to separate from the ground. At this time, the two sets of support frames (221) are in contact with the ground, thereby supporting the entire device. At the same time, the two sets of electric telescopic rods (150) are driven in reverse to drive the track plate (130) to reset, thereby transporting the four sets of hollow rotating drums (123) at the bottom of the device to adjacent positions. Thereafter, the double-axis camel machine (112) is reversed to make the hollow rotating drum (123) contact the ground again, and the motor (124) is driven to move the device back. Repeating the above operation can make the device move in the entire area to be tested. S3: When the device moves in the area to be tested, the hollow rotating cylinder (123) can drive the paddle (127) to rotate, and under the limiting action of the limiting groove (122), the positioning shaft (125) and the spring (126) cannot rotate. At this time, the paddle (127) can periodically paddle each spring (126) to make it vibrate and make a sound. The volume of the noise emitted can be collected by the sound receiver, thereby judging the sound insulation effect of the building; S4: When the thickness of the building to be tested is relatively thick, that is, the sound insulation performance required of the building is relatively strong, while driving the device to move, the second driving motor (214) drives the main shaft (211) to rotate, thereby driving the two sets of crank-connecting rod mechanisms (213) to work, so that the knocking hammer (215) at the bottom of the crank-connecting rod mechanism (213) can perform reciprocating motion, so that the knocking hammer (215) can continuously knock on the ground while the device is moving. At this time, the sound volume of the knocking noise can be collected by the sound receiver, thereby judging the sound insulation effect of the building.
