Description

Technical Field

[0001] This utility model belongs to the field of building engineering management technology, and more specifically, it relates to a building environmental noise detection device. Background Technology

[0002] During the construction process, environmental noise emission standards must be met. Sound level meters can directly measure sound pressure level (dB) and can cover most noise detection scenarios such as construction, indoor environment, and surrounding monitoring. They can help avoid environmental penalties or resident complaints due to excessive noise and are the core tool for obtaining basic noise data. Existing sound level meters for building environmental noise detection generally consist of a sound level meter body, a microphone, a signal processing module, and a display screen.

[0003] Existing application number: CN201822258297.8, this utility model discloses a sound level meter for noise detection, relating to the field of noise detection, to solve the problem in the prior art of real-time detection of noise in the external environment and convenient viewing of detection data. A microcomputer housing is provided on one outer surface of the outer casing, and a microcomputer is installed inside the microcomputer housing. A signal transceiver is connected inside the microcomputer. An ammeter is provided on one side of the microcomputer. Connecting blocks are provided on both outer surfaces of the outer casing, and there are four connecting blocks. A fixing bolt is provided in the middle of each connecting block, and there are four fixing bolts. A connecting rod is provided on one outer surface of the outer casing, and a microphone is provided at one end of the connecting rod. A sponge is installed outside the microphone, and a vibrating diaphragm is provided inside the microphone.

[0004] Based on the above, when a sound level meter is used for long-term measurement, if it is placed directly on a flat surface, the superposition and interference of sound waves due to plane reflection can easily occur, resulting in higher low-frequency measurement values ​​and attenuation of high-frequency components, which in turn affects the accuracy of the data. On construction sites, if it is temporarily raised with bricks or other objects to achieve vertical placement, it is not only cumbersome to operate, but may also introduce additional errors due to unstable support, making it difficult to balance measurement standardization and convenience. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a building environment noise detection device. This device solves the problem that existing sound level meters, when placed directly on a flat surface during long-term measurements, are prone to sound wave superposition interference due to plane reflection, leading to inflated low-frequency measurements and attenuation of high-frequency components, thus affecting data accuracy. Furthermore, at construction sites, temporarily elevating the meter using bricks or other objects for vertical placement is not only cumbersome but may also introduce additional errors due to unstable support, making it difficult to balance measurement standardization and convenience.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a building environment noise detection device, including a sound level meter body 1, a display screen 101, a microphone 102, elastic wrist straps 2, elastic arm straps 3, a fixing box 9, a positioning groove 901, and a linkage placement assembly; the display screen 101 is fixedly connected to the front of the sound level meter body 1; the microphone 102 is fixedly connected to the top of the sound level meter body 1; two elastic wrist straps 2 are provided, and the two elastic wrist straps 2 are fixedly connected to the left and right sides of the sound level meter body 1 respectively; the elastic arm straps 3 are located at the top rear of the sound level meter body 1; the fixing box 9 is fixedly connected to the top rear of the sound level meter body 1; the positioning groove 901 is opened inside the fixing box 9; the linkage placement assembly is located on the left and right sides and the bottom of the sound level meter body 1.

[0029] The linkage placement component includes: an adsorption box 4 and an adsorption magnet 5; two adsorption boxes 4 are provided, and the two adsorption boxes 4 are respectively fixedly connected to the top outer side of the two palm elastic bands 2; two adsorption magnets 5 are provided, and the two adsorption magnets 5 are respectively fixedly connected to the inside of the two adsorption boxes 4.

[0030] The linkage placement component also includes: connector 6 and threaded box 601; connector 6 is fixedly connected to the bottom rear of the sound level meter body 1; threaded box 601 is fixedly connected to the rear of connector 6, and threaded groove is opened inside threaded box 601.

[0031] The linkage placement component also includes: a threaded connecting post 7 and a tripod telescopic support frame 8; the threaded connecting post 7 is threaded into the threaded groove inside the threaded box 601; the tripod telescopic support frame 8 is fixedly connected to the bottom of the threaded connecting post 7.

[0032] The specific usage and function of this embodiment are as follows: During use, the palm can pass through any elastic band 2 for a more secure grip. Simultaneously, the magnetic magnet 5, fixedly connected to the adsorption box 4, allows it to magnetically attach to scaffolding, fences, and other iron structures, facilitating the collection of noise information from specific locations. When long-term placement on a flat surface for noise detection is required, the tripod telescopic support frame 8 can be threaded into the bottom of the threaded box 601 via the threaded connecting post 7, allowing the tripod telescopic support frame 8 to contact the ground. This positions the microphone 102 on top of the sound level meter body 1 upwards. When placed vertically on a flat surface, the microphone is in free space at a certain height above the surface, directly receiving sound waves from above and the surrounding area, reducing interference from reflected sound. This is generally more accurate than when placed flat on a flat surface. The three legs of the tripod telescopic support frame 8 can retract inwards and be threaded into the top of the threaded box 601 via the threaded connecting post 7, allowing the tripod telescopic support frame 8 to be folded up to the back of the sound level meter body 1, minimizing space usage and making it easier to handle.

[0033] Example 2:

[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 It also includes a portable component, which is located at the top rear of the sound level meter body 1.

[0035] The portable components include: a sliding plate 10, a pressing post 1001, and a limiting post 1002; the sliding plate 10 is slidably connected inside the fixed box 9; the pressing post 1001 is fixedly connected to the sliding plate 10; and the limiting post 1002 is fixedly connected to the sliding plate 10.

[0036] The portable components also include: a reset spring 1003, a connecting block 11, and a limiting groove 1101; the top of the reset spring 1003 is fixedly connected to the bottom of the sliding plate 10, and the bottom of the reset spring 1003 is fixedly connected to the inside of the fixing box 9; the bottom of the connecting block 11 is fixedly connected to the top of the sliding plate 10; and the limiting groove 1101 is formed inside the connecting block 11.

[0037] The specific usage and function of this embodiment: When testing personnel need to climb scaffolding in unfinished buildings, they can put the arm elastic band 3 on the outside of their arms in advance. By pressing down on the pressing column 1001, the sliding plate 10 and the limiting column 1002 will retract downwards simultaneously, and the positioning groove 901 will be aligned with the connecting block 11 in front of the arm elastic band 3 for insertion. After releasing the pressing column 1001, the sliding plate 10 and the limiting column 1002 will move upwards under the action of the return spring 1003, and the limiting column 1002 will insert into the limiting groove 1101, so that the sound level meter body 1 and the arm elastic band 3 can be quickly connected. The testing personnel no longer need to hold the sound level meter body 1, and can completely free their hands to focus on climbing operations, which not only ensures the safety of high-altitude operations, but also ensures the stability of the sound level meter body 1.
