Description

Technical Field

[0001] This utility model relates to the field of noise detection technology, specifically a noise detection device. Background Technology

[0002] With the acceleration of urbanization and the vigorous development of industrial production, noise pollution has become one of the most significant environmental problems affecting people's quality of life and endangering human health. Whether it's traffic noise around major transportation routes, industrial noise in industrial parks, or construction noise at building sites, all negatively impact the sleep, work, and physical and mental health of nearby residents. Therefore, real-time and accurate monitoring of environmental noise is the prerequisite and foundation for carrying out noise pollution control and protecting the public's environmental rights. Consequently, noise detection devices are widely used in various fields such as environmental monitoring, urban management, and industrial production.

[0003] Currently, there are many types of noise detection devices on the market, but there are still many problems that need to be solved in actual use. First, in terms of stability, the support structure of existing devices is mostly designed with a fixed size, which cannot flexibly adjust the support range according to the size of the space where it is placed. When used in narrow corridors, indoor corners and other spaces, the fixed large-sized support structure is difficult to place smoothly; while when used in open outdoor areas, the support range is too small, which leads to poor device stability and makes it susceptible to tilting or even falling over due to external forces such as wind and people touching it, thus affecting the accuracy of the detection data.

[0004] Secondly, in terms of site adaptability, existing devices lack an effective leveling mechanism. Environmental noise monitoring often needs to be carried out on uneven sites such as construction sites, roadside green belts, and rugged factory areas. The ground in these sites is uneven, and existing devices are prone to being tilted after placement, which will cause the detection angle of the noise sensor to deviate and affect the comprehensive capture of surrounding environmental noise.

[0005] In view of the shortcomings of the existing noise detection devices in terms of support stability and site adaptability, there is an urgent need to design a noise detection device that can flexibly adjust the support range and has efficient leveling function, so as to improve the applicability and monitoring accuracy of the device in various complex scenarios. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a noise detection device with the advantages of flexible adjustment of the support range and efficient leveling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a noise detection device, comprising a cross-shaped base, an extension mechanism at the top of the cross-shaped base, leveling mechanisms around the extension mechanism, a height adjustment mechanism above the extension mechanism, and a noise monitoring station at the top of the height adjustment mechanism. The extension mechanism can drive the four leveling mechanisms to move closer or further apart, thereby adjusting the footprint of the device. The leveling mechanisms can level the device. The height adjustment mechanisms can adjust the height of the noise monitoring station. The noise monitoring station can detect noise in the surrounding environment.

[0008] In a preferred embodiment of this invention, the extension mechanism includes a slide rail fixedly connected to the top of the cross base. A movable block is slidably connected up and down inside the slide rail. A first threaded rod is rotatably connected inside the slide rail, and the first threaded rod is threadedly connected to the movable block. T-shaped grooves are provided around the circumference of the cross base. T-shaped slide bars are slidably connected inside the T-shaped grooves. The top of each T-shaped slide bar extends above the cross base and is hinged to a connecting rod. The end of the connecting rod away from the T-shaped slide bar is hinged to the movable block. The operator can adjust the rotation of the first threaded rod, thereby causing the movable block to move downwards, which in turn causes the connecting rod to move, and consequently causes the four T-shaped slide bars to move away from each other.

[0009] As a preferred embodiment of this utility model, the leveling mechanism includes a fixed block fixedly connected to the side of the T-shaped slide bar away from the slide rail, and a second threaded rod is internally threaded to the fixed block, with a support pad rotatably connected to the bottom of the second threaded rod.

[0010] As a preferred embodiment of this utility model, the height adjustment mechanism includes a sleeve fixedly connected above the slide rail by a bracket. The top of the sleeve is provided with a groove, and a movable column is slidably connected inside the groove. The top of the movable column is fixedly connected to the bottom of the noise monitoring station. The front of the movable column is provided with multiple slots evenly distributed in the vertical direction. A bolt is threaded inside the sleeve, and the bolt is inserted into the slot.

[0011] In a preferred embodiment of this invention, the top of the first threaded rod extends above the slide rail, and a cylinder is fixedly connected to the top of the slide rail. The inner wall of the cylinder is in contact with the surface of the first threaded rod, and a third threaded rod is threadedly connected to the inside of the cylinder. The third threaded rod is in close contact with the first threaded rod.

[0012] As a preferred embodiment of this utility model, the slide rail is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the slide rail and the inner ring of the bearing fixedly connected to the first threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a cross-shaped base to construct a stable foundation. Combined with the synergistic effect of the extension mechanism, leveling mechanism, height adjustment mechanism, and noise monitoring station, it achieves multi-functional integration. The extension mechanism can flexibly change the device's footprint, allowing for convenient placement in narrow spaces and expanding the support range to improve stability in open areas. The leveling mechanism ensures the device remains level even on uneven ground, preventing tilting from affecting detection accuracy. The height adjustment mechanism can adjust the position of the noise monitoring station according to detection needs, adapting to monitoring height requirements in different scenarios, making noise monitoring more accurate. The overall structural design is reasonable, significantly improving the applicability and practicality of the device. This device has the advantages of flexible adjustment of the support range and efficient leveling.

[0014] 2. This utility model utilizes a combined structure of a slide rail, movable block, first threaded rod, T-shaped slide groove, T-shaped slide bar, and connecting rod in its extension mechanism, achieving convenient adjustment of the support range. The operator simply rotates the first threaded rod to drive the movable block along the slide rail, which in turn drives the T-shaped slide bar to slide within the T-shaped slide groove via the connecting rod, thereby changing the spacing of the four leveling mechanisms. This mechanical transmission method is stable and reliable, avoiding the tediousness and inaccuracy of manual adjustment. Simultaneously, the cooperation between the T-shaped slide groove and the T-shaped slide bar ensures guidance during the sliding process, preventing deviation and making the device easier to operate and run smoothly when adjusting the floor space, thus improving ease of use.

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.

[0018] like Figures 1 to 4 As shown, a noise detection device includes a cross-shaped base 1. An extension mechanism is located on the top of the cross-shaped base 1. Leveling mechanisms are located around the extension mechanism, and a height adjustment mechanism is located above the extension mechanism. A noise monitoring station 2 is located on top of the height adjustment mechanism. The extension mechanism can drive the four leveling mechanisms to move closer or further apart, thereby adjusting the footprint of the device. The leveling mechanisms can level the device, and the height adjustment mechanisms can adjust the height of the noise monitoring station 2. The noise monitoring station 2 can detect noise in the surrounding environment. The noise monitoring station 2 includes a noise sensor, a main unit, an LED display screen, an audible and visual alarm, an antenna, and a support column. The main unit has a built-in processor and data storage module, responsible for converting sensor signals into decibel values ​​and controlling alarms and data transmission. The system includes functions such as LED display showing the current noise level in decibels in real time, and antenna for remote data transmission, such as uploading monitoring data to a management platform. The noise monitoring station 2 described above is a common existing technology and is common knowledge to those skilled in the art, so it will not be described in detail here. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as screws, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, so it will not be described in detail here. The contents not described in detail in this specification are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0019] refer to Figure 1 The extension mechanism includes a slide rail 3 fixedly connected to the top of the cross base 1. A movable block 5 is slidably connected inside the slide rail 3. A first threaded rod 4 is rotatably connected inside the slide rail 3. The first threaded rod 4 is threadedly connected to the movable block 5. T-shaped slide grooves are provided around the cross base 1. T-shaped slide bars 6 are slidably connected inside the T-shaped slide grooves. The top of the T-shaped slide bars 6 extends to the top of the cross base 1 and is hinged to a connecting rod 7. The end of the connecting rod 7 away from the T-shaped slide bars 6 is hinged to the movable block 5. The operator can adjust the rotation of the first threaded rod 4, thereby driving the movable block 5 to move down, thereby driving the connecting rod 7 to move, thereby driving the four T-shaped slide bars 6 to move away from each other.

[0020] As a technical optimization of this utility model, the extension mechanism adopts a combination structure of slide rail 3, movable block 5, first threaded rod 4, T-shaped slide groove, T-shaped slide bar 6, and connecting rod 7, realizing convenient adjustment of the support range. The operator only needs to rotate the first threaded rod 4 to drive the movable block 5 to move along the slide rail 3, and the connecting rod 7 drives the T-shaped slide bar 6 to slide within the T-shaped slide groove, thereby changing the spacing of the four leveling mechanisms. This mechanical transmission method is stable and reliable, avoiding the tediousness and inaccuracy of manual adjustment. At the same time, the cooperation between the T-shaped slide groove and the T-shaped slide bar 6 ensures guidance during the sliding process, preventing deviation, making the device easier to operate and run smoothly when adjusting the floor space, thus improving ease of use.

[0021] refer to Figure 1 The leveling mechanism includes a fixed block 8 fixedly connected to the side of the T-shaped slide bar 6 away from the slide rail 3. The fixed block 8 is internally threaded with a second threaded rod 9, and the bottom of the second threaded rod 9 is rotatably connected with a support pad 10.

[0022] As a technical optimization of this utility model, the leveling mechanism consists of a fixed block 8, a second threaded rod 9, and a support pad 10. This design is simple in structure and provides precise leveling. The fixed block 8 provides stable support for the second threaded rod 9. Rotating the second threaded rod 9 causes it to move up and down, which in turn moves the support pad 10 up and down. When the device is placed on rough or sloping ground, the leveling mechanism can be adjusted separately for different positions to keep the cross base 1 horizontal, preventing uneven force on the noise monitoring station 2 or deviation in detection data due to device tilt.

[0023] refer to Figure 2 The height adjustment mechanism includes a sleeve 11 fixedly connected to the slide rail 3 via a bracket. The top of the sleeve 11 is provided with a groove, and a movable column 12 is slidably connected inside the groove. The top of the movable column 12 is fixedly connected to the bottom of the noise monitoring station 2. The front of the movable column 12 is provided with multiple slots evenly distributed in the vertical direction. The sleeve 11 is threaded with a bolt 13, which is inserted into the slot.

[0024] As a technical optimization of this utility model, the height adjustment mechanism, employing a sleeve 11, a movable column 12, slots, and bolts 13, achieves flexible fixing and adjustment of the height of the noise monitoring station 2. The sleeve 11 is securely connected to the slide rail 3 via a bracket. The movable column 12 slides along the groove of the sleeve 11, raising and lowering the noise monitoring station 2 to meet monitoring needs at different heights. For example, in densely populated areas, the height can be increased to avoid obstruction, while in confined spaces, the height can be lowered for easier placement. Multiple slots on the movable column 12 provide multiple fixing points for the bolts 13. After adjusting to the appropriate height, tightening the bolts 13 and inserting them into the slots achieves secure fixing. This positioning method is simple and efficient, preventing the movable column 12 from sliding on its own and ensuring stable operation of the noise monitoring station 2 at the set height, thus improving the flexibility of detection.

[0025] refer to Figure 3 The top of the first threaded rod 4 extends above the slide rail 3. A cylinder 14 is fixedly connected to the top of the slide rail 3. The inner wall of the cylinder 14 is in contact with the surface of the first threaded rod 4. A third threaded rod 15 is threadedly connected inside the cylinder 14. The third threaded rod 15 is in close contact with the first threaded rod 4.

[0026] As a technical optimization of this utility model, by setting a cylinder 14 on the top of the slide rail 3, and cooperating with the third threaded rod 15 to limit and fix the first threaded rod 4, the locking reliability of the extension mechanism is effectively improved. The top of the first threaded rod 4 extends above the slide rail 3 and fits against the inner wall of the cylinder 14. The cylinder 14 provides additional support for the first threaded rod 4, reducing its shaking during rotation. After the first threaded rod 4 is adjusted to the appropriate position, the third threaded rod 15 is tightened to make it fit tightly against the first threaded rod 4. The friction force restricts the self-rotation of the first threaded rod 4, preventing the first threaded rod 4 from loosening due to device vibration or external force, thereby preventing the T-shaped slide bar 6 from shifting position, ensuring that the device's footprint remains in the set state, providing double protection for the stability of the overall structure, and improving the reliability of the device during use.

[0027] refer to Figure 1 The slide rail 3 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the slide rail 3, while the inner ring of the bearing is fixedly connected to the first threaded rod 4.

[0028] As a technical optimization of this utility model, by setting a bearing inside the slide rail 3, with the outer ring of the bearing fixed to the slide rail 3 and the inner ring fixed to the first threaded rod 4, the rotation performance of the first threaded rod 4 is significantly optimized. The bearing design reduces the frictional resistance between the first threaded rod 4 and the slide rail 3, making it easier and more convenient for the operator to rotate the first threaded rod 4, and avoiding the problem of rotation jamming caused by friction and wear after long-term use. At the same time, the bearing can accurately position the first threaded rod 4, preventing radial displacement during rotation, ensuring that the movable block 5 moves smoothly along the axis of the slide rail 3, thereby ensuring the synchronization and stability of the connecting rod 7 driving the T-shaped slide bar 6, extending the service life of the extension mechanism, and improving the operational reliability of the device.

[0029] The working principle and usage process of this utility model are as follows: After transporting the device to the testing area, first place the cross base 1 stably on the ground and initially adjust its position to ensure there is no significant risk of tipping over. Then, rotate the third threaded rod 15 inside the cylinder 14 to separate it from the first threaded rod 4, releasing the fixation restriction on the first threaded rod 4. Next, grasp the handle at the top of the first threaded rod 4 and rotate it, driving the movable block 5 to slide downwards along the slide rail 3. The movable block 5, through the hinged connecting rod 7, drives the T-shaped slide bars 6 to slide within the T-shaped groove, causing the four T-shaped slide bars 6 to simultaneously unfold away from the slide rail 3 until the spacing of the leveling mechanism reaches a suitable range, improving the overall support stability of the device. After unfolding, rotate the third threaded rod 15 in the opposite direction to make it tightly fit with the first threaded rod 4, fixing the position of the first threaded rod 4 through friction and preventing the T-shaped slide bars 6 from moving on their own.

[0030] Next, observe the horizontal state of the cross base 1. A spirit level can be used to measure the horizontal state of the cross base 1. Locate the leveling mechanism for any uneven areas, rotate the handle of the second threaded rod 9 to move the second threaded rod 9 up and down along the internal thread of the fixed block 8, thereby adjusting the contact height between the support pad 10 and the ground. Fine-tune each leveling mechanism until the cross base 1 is level. After leveling, loosen the bolt 13 on the sleeve 11 to disengage it from the slot of the movable column 12, releasing the fixation of the movable column 12. Pull the noise monitoring station 2 up and down according to the testing requirements, causing the movable column 12 to slide along the groove of the sleeve 11 to a suitable height, ensuring that the noise monitoring station 2 is not obstructed by surrounding obstacles and is in the optimal testing position. Then tighten the bolt 13 to insert the bolt 13 into the slot at the corresponding height to fix the movable column 12.

[0031] Turn on the power switch of noise monitoring station 2, and the main unit starts running. The noise sensor collects the noise signal of the surrounding environment in real time, the processor converts the signal into decibel value, and the LED display shows the current noise data synchronously. If the noise exceeds the set threshold, the audible and visual alarm will automatically activate. During the detection process, the monitoring data can be remotely transmitted and viewed in real time via an antenna. The surfaces of the first threaded rod 4, the second threaded rod 9, and the third threaded rod 15 are all fixedly connected with handles. In actual use, the surfaces of the first threaded rod 4, the second threaded rod 9, and the third threaded rod 15 can be covered with retractable protective sleeves to prevent debris from adhering to their surfaces. Retractable protective sleeves are common existing technology and are common knowledge to those skilled in the art, and will not be described in detail in this application. The retractable protective sleeves are not shown.
