Description

Technical Field

[0001] This invention relates to the field of floor testing technology, specifically to a noise-reducing floor testing device based on intelligent sensing. Background Technology

[0002] Noise-reducing flooring is a flooring material used to reduce indoor sound insulation, thereby reducing low-frequency noise such as footsteps and furniture movement, and significantly improving the acoustic quality of the indoor environment. The main function of the noise-reducing flooring detection device based on intelligent sensing is to detect the sound insulation, vibration reduction and noise reduction performance of the noise-reducing flooring, and to ensure that the noise-reducing flooring achieves the expected noise reduction effect in practical applications.

[0003] Patent CN218481311U discloses a floor flexural strength testing device, belonging to the field of floor testing technology. It includes a base, on which two sets of first hydraulic rods are fixedly mounted on the upper surface. The two sets of first hydraulic rods are symmetrically distributed about the vertical center line of the base. The telescopic ends of the first hydraulic rods are fixedly connected to support platforms for placing the floor. A support frame is fixedly mounted on the upper surface of the support platform. The beneficial effect of this patent is that the floor to be tested can be placed on the surfaces of the two support platforms, so that the part of the floor to be bent and tested is located in the gap between the two support platforms. The second hydraulic rod above can drive the pressure platform to move downwards and press against the floor surface, thereby ensuring its stability. At the same time, a third hydraulic rod in the groove on the lower surface of the pressure platform can push the testing head to apply pressure to the floor until the floor breaks. The pressure sensor inside the testing head can detect the maximum pressure that the floor can withstand.

[0004] However, the current floor flexural strength testing device has the following problems: when using this floor flexural strength testing device, it is difficult to simulate the real environment to test the sound insulation effect of the noise reduction floor, which leads to the problem of poor sound insulation effect of the noise reduction floor. Therefore, we propose a noise reduction floor testing device based on intelligent sensing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a noise-reducing floor detection device based on intelligent sensing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a noise-reducing floor detection device based on intelligent sensing, comprising a base table, a frame fixed to the top surface of the base table, baffles embedded on both sides of the top surface of the frame, a U-shaped frame fixed in the middle of the top surface of the base table, the U-shaped frame located below the frame, an intelligent sound sensor fixedly installed at the bottom of the U-shaped frame, a round rod rotatably mounted through the top of the inner wall of the U-shaped frame, a motor fixed to the top surface of the base table, the motor located on the right side of the frame, a transmission module fixed to the back of the motor's shaft, the front of the transmission module being fixedly connected to the back of the round rod, the transmission module comprising two I-shaped discs and a belt, one I-shaped disc fixed to the back of the motor's shaft, the other I-shaped disc fixed to the back of the round rod, and the belt rotatably mounting the two I-shaped discs. On the inner wall, a double-ring frame is fixed in the middle of the outer wall of the round rod. The double-ring frame is located above the frame. Square shells are fixed on the left and right sides of the double-ring frame. Sliding grooves are opened on the front and back of the two square shells. A sliding shell is slidably installed on the inner wall of each square shell. The outer wall of each sliding shell slides in contact with the inner wall of the sliding groove of each square shell. Two springs are respectively arranged between the inner wall of each square shell and each sliding shell. A semi-circular block is embedded on the side of the two sliding shells that are far apart from each other. When the sliding shell rotates to the bottom, under the action of gravity, the sliding shell moves downward in the sliding groove of the square shell. The sliding shell drives the semi-circular block to move downward. The rubber pad on the semi-circular block taps the surface of the floor sample. When the square shell rotates to the top, under the elastic force of the spring, the sliding shell returns to its original position in the square shell, allowing the rubber pad on the semi-circular block to tap the surface of the floor sample repeatedly.

[0007] According to the above technical solution, the bottom of the table is provided with support legs on all four sides, and each support leg has a foot fixed to its bottom surface. Each foot has a reinforcing rib on its outer wall.

[0008] According to the above technical solution, a tripod is provided at the bottom of the outer wall of the motor, the bottom surface of the tripod is fixedly connected to the top surface of the base table, and rubber pads are provided on the arc surfaces of the two semi-arc blocks.

[0009] According to the above technical solution, the outer wall of the round rod is provided with a clamping plate device, which is used to clamp the floor when the semi-circular block strikes the noise-reducing floor. The top surface of the clamping plate device is provided with an edge pressing device, which is used to detect the edge pressure resistance of the noise-reducing floor.

[0010] According to the above technical solution, two tube rods are fixed to the outer wall of the round rod. A vertical groove plate is rotatably installed on the outer wall of each tube rod. The bottom surfaces of the two vertical groove plates are fixedly connected to the bottom of the U-shaped frame. A sliding groove is opened in the middle of opposite sides of each of the two vertical groove plates. A horizontal plate is slidably installed on the inner wall of the sliding groove of each vertical groove plate. Two sliding holes are opened on the top surface of each horizontal plate. A U-shaped rod is slidably installed on the inner wall of each of the two sliding holes of each horizontal plate. The bottom surfaces of the two U-shaped rods are fixedly connected to the top surface of the base table. The bottom surface of each horizontal plate is connected to the top surface of the base table. Two springs are respectively provided, and the four springs are respectively sleeved on the outer wall of two U-shaped rods. Rectangular plates are fixed on both sides of the bottom surface of the two horizontal plates. The two rectangular plates are located above the frame. Rubber pads are provided on the bottom surface of the two rectangular plates. During the rotation of the tube rod, it contacts the horizontal plate. Under the action of the extrusion force, the horizontal plate slides downward on the U-shaped rod. The horizontal plate drives the rectangular plate to move downward. The rubber pads on the rectangular plates press against the floor sample on the frame. When the tube rod rotates away from the horizontal plate, under the elastic force of the springs, the horizontal plate drives the rectangular plate upward away from the floor sample.

[0011] According to the above technical solution, two connecting plates are fixed on the top surface of each of the horizontal plates, an L-shaped rod is fixed on the top surface of each of the connecting plates, and a semi-arc plate is fixed at the end of each L-shaped rod away from each connecting plate. The four semi-arc plates are located on the side of the two horizontal plates that are far apart from each other. The L-shaped rod drives the semi-arc plates to move downward, and the semi-arc plates block the compressed spring.

[0012] According to the above technical solution, a triangular plate is fixedly installed on the top surface of each rectangular plate, a cylinder is embedded in the top surface of each triangular plate, a sliding column is slidably installed on the inner wall of each cylinder, a spring is provided between the top surface of each sliding column and the inner top of each cylinder, and a strip is fixed on the bottom surface of each sliding column. The strip is located below the rectangular plate, and it contacts the edge of the floor sample during the downward movement of the strip, and the strip presses the edge of the floor sample.

[0013] According to the above technical solution, a plate is fixed on the top surface of each cylinder, and a short column is fixed on the bottom surface of each plate. The two short columns are located on the side of the two cylinders that are close to each other. A square plate is fixed on the bottom surface of each short column. The bottom surfaces of the two square plates are fixedly connected to the top surfaces of the two triangular plates. The plate supports the cylinder to move downward, and the cylinder moves downward stably under the support of the plate.

[0014] This invention provides a noise-reducing floor detection device based on intelligent sensing. It has the following beneficial effects:

[0015] (1) This invention uses a base table, frame, baffle, U-shaped frame, intelligent sound sensor, round rod, motor, transmission module, double ring frame, square shell, sliding shell and spring-1 in conjunction with a semi-circular block. When the sliding shell rotates to the bottom, it moves downward in the sliding groove of the square shell under the action of gravity. The sliding shell pulls the spring-1 to move downward. The spring-1 is pulled up by the sliding shell. The sliding shell drives the semi-circular block to move downward. The rubber pad on the semi-circular block taps the surface of the floor sample. When the square shell rotates to the top, the sliding shell resets in the square shell under the elastic force of the spring-1, so that the rubber pad on the semi-circular block taps the surface of the floor sample repeatedly. The intelligent sound sensor receives the noise of the semi-circular block tapping the floor sample, allowing the equipment to simulate real footsteps for sound insulation testing. This prevents the equipment from being unable to simulate real footsteps for sound insulation testing, resulting in poor sound insulation effect of the noise reduction floor test.

[0016] (2) The present invention uses a clamping device to make the tube rod, vertical groove plate, horizontal plate, U-shaped rod and spring 2 cooperate with the rectangular plate. The tube rod contacts the horizontal plate during rotation. Under the action of the squeezing force, the horizontal plate slides down on the U-shaped rod. The horizontal plate drives the rectangular plate to move down. The rubber pad on the rectangular plate presses the floor sample on the frame. When the tube rod rotates away from the horizontal plate, under the action of the elastic force of spring 2, the horizontal plate drives the rectangular plate to move up away from the floor sample. When the semi-circular block hits the surface of the floor sample, the rubber pad on the rectangular plate and the frame clamp the floor sample, so that the rectangular plate can flexibly clamp the floor sample, simulate the state when the floor is installed, reduce the violent vibration of the floor sample when it is hit, prevent the violent vibration of the floor sample from causing inaccurate sound insulation effect detection, and avoid the floor sample being clamped on the frame for a long time, which would cause deformation and damage to the surface of the floor sample.

[0017] (3) The present invention uses a clamping device to make the connecting plate and the L-shaped rod cooperate with the semi-arc plate. The L-shaped rod drives the semi-arc plate to move downward. The semi-arc plate blocks the compressed spring 2, preventing the spring 2 from accidentally injuring the operator during the compression process and causing poor equipment performance.

[0018] (4) The present invention uses a pressing device to make the triangular plate, cylinder, sliding column and spring work together as the plate moves downward and contacts the edge of the floor sample. The plate presses the edge of the floor sample and the pressing of the plate can detect the compressive strength of the edge of the floor sample, thus preventing the equipment from being unable to detect the compressive strength of the edge of the floor sample and thus preventing the equipment from having a single detection capability.

[0019] (5) By setting the edge pressing device, the present invention enables the plate and short column to cooperate with the square plate, and the plate supports the cylinder to move downward, so that the cylinder moves downward stably under the support of the plate, so that the cylinder will not shake when squeezed, and prevent the cylinder from being squeezed and causing violent shaking, which would cause the equipment to detect unstable floor samples.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1-7One embodiment of the present invention is as follows: a noise-reducing floor detection device based on intelligent sensing, comprising a base table 1, a frame 2 fixed to the top surface of the base table 1, baffles 3 embedded on both sides of the top surface of the frame 2, a U-shaped frame 4 fixed in the middle of the top surface of the base table 1, the U-shaped frame 4 being located below the frame 2, an intelligent sound sensor 5 fixedly installed at the bottom of the inside of the U-shaped frame 4, a round rod 6 rotatably installed through the top of the inner wall of the U-shaped frame 4, a motor 7 fixed to the top surface of the base table 1, the motor 7 being located on the right side of the frame 2, a transmission module 8 fixed to the back of the rotating shaft of the motor 7, and the front of the transmission module 8 being fixedly connected to the back of the round rod 6. The transmission module 8 includes two I-shaped discs and a belt. One I-shaped disc is fixed to the back of the shaft of the motor 7, and the other I-shaped disc is fixed to the back of the round rod 6. The belt is rotatably mounted on the inner wall of the two I-shaped discs. A double-ring frame 9 is fixed in the middle of the outer wall of the round rod 6. The double-ring frame 9 is located above the frame 2. Square shells 10 are fixed on both the left and right sides of the double-ring frame 9. Sliding grooves are opened on the front and back of the two square shells 10. A sliding shell 11 is slidably installed on the inner wall of each square shell 10. The outer wall of each sliding shell 11 is in sliding contact with the inner wall of the sliding groove of each square shell 10. Two springs 12 are provided. A semi-circular block 13 is embedded in each of the two sliding shells 11 on their opposite sides. A tripod is installed at the bottom of the outer wall of the motor 7, and the bottom surface of the tripod is fixedly connected to the top surface of the base table 1. Rubber pads are provided on the curved surfaces of the two semi-circular blocks 13. Support legs are provided on all four sides of the base table 1, and a foot 16 is fixed to the bottom surface of each support leg. Each foot 16 has reinforcing ribs on its outer wall. When the sliding shell 11 rotates to the lower position, it moves downwards in the groove of the square shell 10 under the action of gravity. The sliding shell 11 pulls the springs 12 downwards. Spring 12 is pulled up by sliding shell 11, which drives semi-circular block 13 to move downward. The rubber pad on semi-circular block 13 taps the surface of the floor sample. When the square shell 10 rotates to the top, under the elastic force of spring 12, sliding shell 11 returns to its original position in the square shell 10, causing the rubber pad on semi-circular block 13 to repeatedly tap the surface of the floor sample. The intelligent sound sensor 5 receives the noise from semi-circular block 13 tapping the floor sample, allowing the device to simulate real footsteps for sound insulation testing. This avoids the problem that the testing device cannot simulate real footsteps for sound insulation testing when testing noise-reducing flooring, resulting in poor sound insulation performance of the noise-reducing flooring.

[0030] The outer wall of the round rod 6 is provided with a clamping device 14, which is used to clamp the floor when the semi-circular block 13 strikes the noise reduction floor. The top surface of the clamping device 14 is provided with a pressing device 15, which is used to test the edge pressure resistance of the noise reduction floor.

[0031] Because the equipment cannot simulate a real environment to test the sound insulation effect of noise-reducing flooring during testing, when using this equipment, the base 16 supports the base table 1, the base table 1 supports the frame 2, the operator places the noise-reducing flooring sample on the frame 2, the baffle 3 limits the flooring sample, the operator starts the motor 7 on the base table 1, the shaft of the motor 7 starts to reverse, the shaft of the motor 7 drives the I-shaped disc of the transmission module 8 to reverse, under the action of friction, the I-shaped disc drives the belt to reverse, the belt drives another I-shaped disc to reverse, the other I-shaped disc drives the round rod 6 to reverse, the round rod 6 reverses in the U-shaped frame 4, the round rod 6 drives the double ring frame 9 to reverse, the double ring frame 9 drives the square shell 10 to reverse, the square shell 10 drives the sliding shell 11 to reverse, the sliding shell 11 drives the semi-circular block 13 to reverse, when the sliding shell 11 rotates to the bottom, under the influence of gravity... Under the action of force, the sliding shell 11 moves downward in the groove of the square shell 10. The sliding shell 11 pulls the spring 12 downward, and the spring 12 is pulled up by the sliding shell 11. The sliding shell 11 drives the semi-circular block 13 to move downward. The rubber pad on the semi-circular block 13 taps the surface of the floor sample. When the square shell 10 rotates to the top, under the action of the elastic force of the spring 12, the sliding shell 11 returns to its original position in the square shell 10, so that the rubber pad on the semi-circular block 13 taps the surface of the floor sample repeatedly. The intelligent sound sensor 5 receives the noise from the semi-circular block 13 tapping the floor sample, allowing the device to simulate real footsteps for sound insulation testing. This prevents the device from being unable to simulate real footsteps for sound insulation testing during use, thus avoiding the problem of poor sound insulation effect of the noise-reducing floor test when the testing device is unable to simulate real footsteps for sound insulation testing.

[0032] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, two tube rods 141 are fixed to the outer wall of the round rod 6. A vertical groove plate 142 is rotatably installed on the outer wall of each tube rod 141. The bottom surfaces of the two vertical groove plates 142 are fixedly connected to the bottom of the U-shaped frame 4. A sliding groove is opened in the middle of the two vertical groove plates 142 opposite each other. A horizontal plate 143 is slidably installed on the inner wall of the sliding groove of each vertical groove plate 142. Two sliding holes are opened on the top surface of each horizontal plate 143. A U-shaped rod 144 is slidably installed on the inner wall of the two sliding holes of each horizontal plate 143. The bottom surfaces of the two U-shaped rods 144 are fixedly connected to the top surface of the base table 1. Two springs 145 are respectively arranged between the bottom surface of each horizontal plate 143 and the top surface of the base table 1. Four springs 145 are respectively sleeved on the outer walls of the two U-shaped rods 144. Rectangular plates 146 are fixed on both sides of the bottom surface of the two horizontal plates 143. The two rectangular plates 146 are located above the frame 2. A rubber pad is provided on the bottom surface of plate 146. During the rotation of tube rod 141, it contacts horizontal plate 143. Under the action of extrusion force, horizontal plate 143 slides downward on U-shaped rod 144. Horizontal plate 143 drives rectangular plate 146 to move downward. The rubber pad on rectangular plate 146 presses against the floor sample on frame 2. When tube rod 141 rotates away from horizontal plate 143, under the elastic force of spring 145, horizontal plate 143 drives rectangular plate 146 upward away from the floor sample. This allows the rubber pad on rectangular plate 146 and frame 2 to clamp the floor sample when semi-circular block 13 strikes the surface of the floor sample, enabling rectangular plate 146 to flexibly clamp the floor sample, simulating the state during floor installation. This reduces the violent vibration of the floor sample during striking, preventing inaccurate sound insulation detection caused by violent vibration when the testing device strikes the floor sample during noise reduction floor testing, and preventing the floor sample from being continuously clamped on frame 2, causing deformation and damage to the floor sample surface.

[0033] Two connecting plates 147 are fixed to the top surface of each horizontal plate 143. An L-shaped rod 148 is fixed to the top surface of each connecting plate 147. A semi-circular plate 149 is fixed to the end of each L-shaped rod 148 away from each connecting plate 147. The four semi-circular plates 149 are located on the side of the two horizontal plates 143 that are far apart from each other. The L-shaped rod 148 drives the semi-circular plates 149 to move downward. The semi-circular plates 149 block the compressed spring 145, so as to avoid the spring 145 accidentally injuring the operator during the compression process when the detection device detects the noise reduction floor, which would cause the equipment to be ineffective.

[0034] Each rectangular plate 146 has a triangular plate 151 fixedly installed on its top surface. Each triangular plate 151 has a cylinder 152 embedded in its top surface. Each cylinder 152 has a sliding column 153 slidably installed on its inner wall. A spring 154 is provided between the top surface of each sliding column 153 and the inner top of each cylinder 152. Each sliding column 153 has a strip 155 fixed on its bottom surface. The strip 155 is located below the rectangular plate 146. As the strip 155 moves downward, it contacts the edge of the floor sample and presses against the edge of the floor sample. This allows the strip 155 to press down and detect the compressive strength of the floor sample edge, thus avoiding the problem of the device being unable to detect the compressive strength of the floor sample edge when testing noise-reducing flooring, which would result in the device having limited testing capabilities.

[0035] Each cylinder 152 has a plate 156 fixed to its top surface, and a short post 157 fixed to the bottom surface of each plate 156. The two short posts 157 are located on the side of the two cylinders 152 that are close to each other. A square plate 158 is fixed to the bottom surface of each short post 157. The bottom surfaces of the two square plates 158 are fixedly connected to the top surfaces of the two triangular plates 151. The plate 156 supports the cylinder 152 to move downward, so that the cylinder 152 moves downward stably under the support of the plate 156, so that the cylinder 152 will not shake when squeezed, and avoid the cylinder 152 being squeezed and causing violent shaking when the testing device tests the noise reduction floor, which would cause the equipment to test the floor sample instably.

[0036] As the round rod 6 rotates in reverse within the U-shaped frame 4, it drives the tube rod 141 to rotate in reverse as well. The tube rod 141 rotates in reverse within the vertical slot plate 142. During rotation, the tube rod 141 contacts the horizontal plate 143. Under the pressure, the horizontal plate 143 moves downward within the vertical slot plate 142 and slides downward on the U-shaped rod 144. The second spring 145 on the horizontal plate 143 begins to contract, causing the horizontal plate 143 to drive the rectangular plate 146 downward. During this downward movement, the rubber pad on the rectangular plate 146 presses against the floor sample on the frame 2. When the tube rod 141 rotates away from the horizontal plate 143, under the elastic force of the second spring 145, the horizontal plate 143... The plate 143 slides upward on the U-shaped rod 144. The horizontal plate 143 drives the rectangular plate 146 upward away from the floor sample. When the semi-circular block 13 taps the surface of the floor sample, the rubber pad on the rectangular plate 146 and the frame 2 clamp the floor sample, allowing the rectangular plate 146 to flexibly hold the floor sample, simulating the state when the floor is installed. This reduces the violent vibration of the floor sample when tapped, and prevents the floor sample from vibrating violently when the equipment is in use. This avoids the problem of inaccurate sound insulation effect detection caused by violent vibration of the floor sample when the testing device taps the floor sample during the testing of noise reduction floor. At the same time, it avoids the floor sample being constantly clamped on the frame 2, which would cause deformation and damage to the surface of the floor sample.

[0037] As the horizontal plate 143 slides downward on the U-shaped rod 144, the horizontal plate 143 drives the connecting plate 147 to move downward. The connecting plate 147 drives the L-shaped rod 148 to move downward. The L-shaped rod 148 drives the semi-arc plate 149 to move downward. During the downward movement of the semi-arc plate 149, the semi-arc plate 149 blocks the compressed spring 145, preventing the spring 145 from accidentally injuring the operator during the compression process when the equipment is in use. This avoids the problem of the detection device injuring the operator during the compression process when testing the noise reduction floor, resulting in poor equipment performance.

[0038] As the horizontal plate 143 moves the rectangular plate 146 downwards, the rectangular plate 146 moves the triangular plate 151 downwards, the triangular plate 151 moves the cylinder 152 downwards, the cylinder 152 moves the sliding column 153 downwards, and the sliding column 153 moves the strip 155 downwards. During its downward movement, the strip 155 contacts the edge of the floor sample. Under the pressure, the sliding column 153 slides upwards within the cylinder 152, and the spring 154 on the sliding column 153 begins to contract. Under the elastic force of the spring 154, the strip... When the sound insulation test is completed, the operator removes the floor sample from the frame 2. If the edge of the floor sample is damaged, it means that the edge compressive strength of the floor sample is not up to standard. Conversely, if the edge is intact, it means that the floor sample is qualified. This allows the equipment to test the compressive strength of the floor sample edge when the plate 155 is pressed down. This prevents the equipment from being unable to test the edge compressive strength of the floor sample during use, thus avoiding the problem of the equipment having limited testing capabilities when testing noise-reducing flooring.

[0039] While the rectangular plate 146 drives the triangular plate 151 to move downward, the triangular plate 151 drives the square plate 158 to move downward, the square plate 158 drives the short column 157 to move downward, and the short column 157 drives the plate 156 to move downward. The plate 156 supports the cylinder 152 to move downward, so that the cylinder 152 moves downward stably under the support of the plate 156, preventing the cylinder 152 from shaking during compression. This prevents the cylinder 152 from shaking violently when compressed during use, thus avoiding the problem of unstable testing of floor samples caused by the cylinder 152 shaking violently when compressed during the testing of noise-reducing flooring.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
