Abstract
Description
Technical Field
[0001] This invention relates to the field of noise monitoring device technology, and in particular to an automatic noise monitoring device for low-noise environments. Background Technology
[0002] Low-noise environment noise automatic monitoring devices are mainly used in residential areas and living areas to capture low-intensity noise signals in the environment in real time and automatically, accurately record data such as noise decibel value and duration, and provide reliable data support for noise pollution control, assessment and optimization of the quality of residents' living environment.
[0003] Traditional low-noise automatic monitoring devices are mostly directly fixed to walls, railings, and other carriers without dedicated vibration isolation components. While some devices may have vibration isolation structures, they often use only simple buffer components such as single springs and rubber pads. Such designs cannot cope with the complex vibration environments of residential areas. Vibrations are easily transmitted directly to the monitoring device, causing additional interference to the sensor. They only provide unidirectional buffering without auxiliary buffering mechanisms, and vibration interference distorts low-noise monitoring data, making it impossible to accurately identify weak noise signals. This makes it difficult to meet the high environmental stability requirements of low-noise monitoring in residential areas, limiting the practical value of these devices in such settings. Summary of the Invention
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a low-noise environment noise automatic monitoring device. This solves the problem that existing devices lack dedicated vibration isolation components or only have simple buffers, making it difficult to cope with complex vibration differences, distorted monitoring data, and meet the low-noise monitoring requirements of residential areas.

[0006] According to the low-noise environmental noise automatic monitoring device of the present invention, the longitudinal vibration isolation component includes a double-section slide rail and two sliding blocks. The double-section slide rail is fixed to the upper surface of the bearing plate. The double-section slide rail is formed by two slide rails with the same structure joined end to end along the same straight line. The two sliding blocks are respectively slidably embedded in the two slide rails of the double-section slide rail. A spring and a damper are respectively fixed between each sliding block and the inner bottom surface of the corresponding slide rail.
[0007] According to the low-noise environmental noise automatic monitoring device of the present invention, the longitudinal vibration isolation component further includes two cranks, one end of each of the two cranks is hinged to the upper surface of the two sliding blocks, the free ends of the two cranks are hinged to the lower surface of the frame in an inclined manner, and the inclination directions of the two cranks are opposite and symmetrically distributed.
[0008] According to the low-noise environmental noise automatic monitoring device of the present invention, the transverse vibration isolation component includes a transverse slide rail and a longitudinal slide rail. The transverse slide rail is fixed to one side surface of the fixed block, and the longitudinal slide rail is fixed to the lower surface of the fixed block. The transverse slide rail and the longitudinal slide rail are arranged at a 90-degree angle.
[0009] According to the low-noise environmental noise automatic monitoring device of the present invention, the transverse vibration isolation component further includes a transverse slider and a longitudinal slider. The transverse slider is slidably embedded in a transverse slide rail, and the longitudinal slider is slidably embedded in a longitudinal slide rail.

[0012] Beneficial effects:
[0013] In the low-noise environment noise automatic monitoring device of this technical solution, during lateral vibration isolation, the remaining kinetic energy after multi-stage buffering is finally transferred to the bearing plate, causing the bearing plate to generate a small vertical vibration. At this time, the longitudinal vibration isolation component finally isolates the small longitudinal vibration through crank one, sliding block, spring one and damper one, realizing the whole process buffering of "lateral vibration → lateral buffering → longitudinal buffering → final isolation".
[0014] During longitudinal vibration isolation, the lifting vibration of the bearing plate is synchronously transmitted to the longitudinal spring and longitudinal damper, and then transmitted in the opposite direction to the transverse spring and transverse damper, forming a synergistic effect of "longitudinal vibration → longitudinal buffering → transverse auxiliary buffering".

[0022] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0023] Reference Figure 1-4 This invention provides an automatic environmental noise monitoring device for low noise environments, comprising: a mounting frame 1. Considering that the existing device frame 7 cannot adapt to vibration displacement after installation and is prone to secondary vibration interference due to installation rigidity, two parallel transverse sliding rods 3 are fixedly connected to the inner surface of the mounting frame 1. Two connecting blocks 4 are slidably sleeved on the outer walls of the two transverse sliding rods 3 respectively. A longitudinal sliding rod 5 is fixedly connected between the two connecting blocks 4 on the corresponding side. The outer walls of the two longitudinal sliding rods 5 are slidably sleeved on the frame 7.
[0024] The frame 7 can slide along the transverse slide 3 via the longitudinal slide bar 5 and the connecting block 4 to achieve horizontal displacement compensation. The longitudinal slide bar 5 allows the frame 7 to slide left and right, providing a stable and self-adaptive installation foundation for the subsequent vibration isolation components and avoiding the vibration transmission and amplification problem caused by rigid installation.
[0025] Considering that existing longitudinal vibration isolation devices are mostly single buffers, which are prone to uneven stress and tilting, and the longitudinal vibration is not completely weakened, a longitudinal vibration isolation component is installed on the lower surface of the frame 7. The longitudinal vibration isolation component includes a double-section slide rail 12 and two sliding blocks 13. The double-section slide rail 12 is fixed to the upper surface of the bearing plate 8. The double-section slide rail 12 is composed of two slide rails with the same structure connected end to end along the same straight line. The two sliding blocks 13 are respectively slidably embedded in the two slide rails of the double-section slide rail 12. A spring-9 and a damper-10 are respectively fixed between each sliding block 13 and the inner bottom surface of the corresponding slide rail. The longitudinal vibration isolation component also includes two cranks-11. One end of the two cranks-11 is hinged to the upper surface of the two sliding blocks 13. The free ends of the two cranks-11 are hinged to the lower surface of the frame 7 in an inclined manner, and the inclination directions of the two cranks-11 are opposite and symmetrically distributed.
[0026] During longitudinal vibration, the lifting and lowering of the bearing plate 8 pushes the sliding block 13 to slide in the opposite direction within the double-section slide rail 12 through the symmetrical crank 11, squeezing the spring 9 and damper 10 to absorb vibration and dissipate energy, converting longitudinal vibration into horizontal kinetic energy for efficient buffering, and greatly improving the longitudinal vibration isolation stability and effect.
[0027] Considering that the existing monitoring housing is directly fixed, vibration is easily transmitted directly to the sensor, resulting in distortion of low-noise monitoring data, a support plate 8 is provided below the longitudinal vibration isolation component, and the noise monitoring device housing 2 is fixed to the upper surface of the support plate 8.
[0028] Specifically: The noise monitoring device housing 2 is a protective shell used to house and protect the internal sensors, data acquisition and other components of the noise monitoring device. The noise monitoring device is a device that can automatically capture, collect and analyze noise signals in low-noise environments such as residential areas, and accurately record noise-related data to achieve automatic environmental noise monitoring. This is an existing mature technology that is well known to people in this field, so it will not be described in detail in this document.
[0029] The bearing plate 8 is fixed to the noise monitoring device housing 2 and is flexibly connected to the frame 7 through the longitudinal vibration isolation component. It receives and transmits vibration to the vibration isolation component, blocks the direct transmission path of vibration, provides a stable working environment for the sensors inside the noise monitoring device housing 2, and ensures the accuracy of low-noise signal acquisition.
[0030] Considering the problem that existing lateral vibration isolation cannot convert lateral vibration into a multi-stage bufferable motion form and the buffering is incomplete, a fixing block 6 is fixed to the lower surface of the frame 7. A lateral vibration isolation component is installed below the fixing block 6. The lateral vibration isolation component includes a lateral slide rail 17 and a longitudinal slide rail 20. The lateral slide rail 17 is fixed to one side surface of the fixing block 6, and the longitudinal slide rail 20 is fixed to the lower surface of the fixing block 6. The lateral slide rail 17 and the longitudinal slide rail 20 are set at a 90-degree angle. The lateral vibration isolation component also includes a lateral slider 18 and a longitudinal slider 21. The lateral slider 18 is slidably embedded in the lateral slide rail 17, and the longitudinal slider 21 is slidably embedded in the longitudinal slide rail 20. A crank 19 is hinged to the lower surface of the lateral slider 18, and the other end of the crank 19 is hinged to one side surface of the longitudinal slider 21.
[0031] During lateral vibration, the lateral slider 18 slides along the lateral slide rail 17, and through the crank 19, it drives the longitudinal slider 21 to slide vertically along the longitudinal slide rail 20, realizing the transformation of motion form and converting lateral vibration into longitudinally bufferable motion, thus building a transmission path for subsequent multi-stage buffering of spring 9 and damper 10.
[0032] Considering the issue of vibration transmission, the lateral vibration isolation assembly also includes a lateral damper 14, a lateral spring 16, a longitudinal damper 22, and a longitudinal spring 23. The lateral damper 14 and the lateral spring 16 are both fixed to one side surface of the lateral slider 18, and the longitudinal damper 22 and the longitudinal spring 23 are both fixed to the lower surface of the longitudinal slider 21. The lateral vibration isolation assembly also includes two abutment blocks 15, which are respectively fixed to the free ends of the lateral damper 14, the lateral spring 16, the longitudinal damper 22, and the longitudinal spring 23. One abutment block 15 abuts against the inner side wall of the mounting bracket 1, and the other abutment block 15 abuts against the upper surface of the bearing plate 8.
[0033] During lateral vibration, the lateral spring 16 and lateral damper 14 abut against the mounting bracket 1 through the abutment block 15 to buffer the transmitted longitudinal vibration. The longitudinal spring 23 and longitudinal damper 22 abut against the bearing plate 8 through the abutment block 15 to buffer the vibration of the buffer components, thereby absorbing the vibration kinetic energy in multiple stages and improving the overall vibration isolation effect.
[0034] In summary, the improvements in this embodiment are as follows:
[0035] During lateral vibration isolation, the remaining kinetic energy after multi-stage buffering is finally transferred to the bearing plate 8, causing the bearing plate 8 to generate a small vertical vibration. At this time, the longitudinal vibration isolation component uses crank 11, sliding block 13, spring 9 and damper 10 to finally isolate the small longitudinal vibration, realizing the whole process of "lateral vibration → lateral buffering → longitudinal buffering → final isolation".
[0036] During longitudinal vibration isolation, the lifting vibration of the bearing plate 8 is synchronously transmitted to the longitudinal spring 23 and the longitudinal damper 22, and then transmitted in the opposite direction to the transverse spring 16 and the transverse damper 14, forming a synergistic effect of "longitudinal vibration → longitudinal buffering → transverse auxiliary buffering". The two sets of components assist each other, greatly improving the vibration isolation effect against vibration in a single direction.
[0037] Working principle: When the device is working, the mounting frame 1 forms a movable mounting base through the transverse slide bar 3, the connecting block 4 and the longitudinal slide bar 5. The frame 7 can slide along the longitudinal slide bar 5 and the connecting block 4 along the transverse slide bar 3 to achieve horizontal displacement compensation and avoid vibration transmission and amplification caused by rigid installation.
[0038] When encountering longitudinal vibration, the bearing plate 8 drives the noise monitoring device housing 2 to rise and fall. The symmetrically inclined crank 11 pushes the two sliding blocks 13 to slide in the opposite direction along the double-section slide rail 12. The sliding blocks 13 squeeze the spring 9 and the damper 10, converting the longitudinal vibration kinetic energy into horizontal sliding buffer kinetic energy, thus achieving efficient vibration absorption and dissipation.
[0039] When encountering lateral vibration, the lateral slider 18 slides along the lateral slide rail 17, and the crank 2 19 drives the longitudinal slider 21 to slide vertically along the longitudinal slide rail 20. The lateral spring 16 and the lateral damper 14 abut against the mounting bracket 1 through the abutment block 15 to buffer the vibration. The remaining kinetic energy is transferred to the bearing plate 8 and drives it to rise and fall slightly, and is finally isolated by the longitudinal vibration isolation component.
[0040] Simultaneously, during longitudinal vibration, the lifting vibration of the bearing plate 8 is transmitted synchronously to the longitudinal spring 23 and the longitudinal damper 22, and in the opposite direction to the transverse spring 16 and the transverse damper 14 for auxiliary buffering. The two sets of components work together to achieve full-process vibration isolation and ensure that the sensors in the monitoring housing 2 can stably collect low-noise signals.
[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
