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

[0002] With the acceleration of urbanization and the increasing frequency of industrial production activities, noise pollution has become an important issue affecting environmental quality and residents' quality of life. The sudden and mobile nature of non-stationary noise sources poses significant challenges to their monitoring and control.

[0003] A search revealed that Chinese Patent Publication No. CN 221325672 U discloses a noise detection device, comprising a noise detector and a storage box fitted over it. The top of the storage box is open, and a support plate is slidably fitted inside the storage box. The noise detector is magnetically attached to the top of the support plate, and a U-shaped plate is fixedly fitted inside the storage box, with its inner side adapted to the noise detector. This invention, through a series of structural features, facilitates the removal and support of the noise detector during use, allows for integrated storage and protection when not in use or being carried, and provides a safety buffer and shielding effect from above during use, reducing the risk of accidental damage from falling objects and improving safety. It integrates storage, support, and upper protection into one unit, eliminating the need for separate carrying or tripods, making it convenient for users, improving portability, and facilitating subsequent disassembly and maintenance of the noise detector.

[0004] The noise monitoring device in the aforementioned patent still has certain shortcomings. As most existing traditional noise monitoring methods rely on fixed monitoring stations or fixed equipment, these devices can continuously monitor fixed sound sources in a long-term and stable manner. However, they are not applicable to monitoring non-fixed sound sources for sudden noise in cities, and have obvious limitations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a portable directional noise monitoring system. This solves the problem that most traditional noise monitoring methods rely on fixed monitoring stations or fixed equipment. While these devices can continuously and stably monitor fixed sound sources over a long period, they are not suitable for monitoring non-fixed sound sources in urban areas, and thus have obvious limitations.

[0006] This utility model provides the following technical solution: a portable directional noise monitor, including a support base, a portable protective component on the top of the support base, a directional noise monitor on the support base, two fixing clamping components symmetrically arranged on both sides of the directional noise monitor, and movable wheels evenly installed around the bottom of the support base;

[0007] The portable protective assembly includes support poles vertically arranged around the top of the support base. A first mounting groove is formed on one side of the support pole, and a second mounting groove is formed on the other side. A limiting sliding groove is formed on the side wall of the second mounting groove. A top cover plate is provided on the top of the support base. Two first connecting plates are symmetrically fixed on both sides of the bottom end of the top cover plate, and two second connecting plates are symmetrically fixed on both outer sides of the bottom end of the top cover plate. The first connecting plates are slidably inserted into the first mounting groove, and the second connecting plates are slidably inserted into the second mounting groove. Two connecting screws are symmetrically fixed on both sides of the ends of the second connecting plates. The connecting screws all pass through the limiting sliding groove, and a fixing nut is sleeved on the end of the connecting screw.

[0008] Preferred technical solution 1: The fixing clamping assembly includes drive grooves symmetrically opened on both sides of the top end of the support base, and a drive screw is rotatably arranged in each drive groove. The end of the drive screw rotatably passes through the drive groove and extends to the outside of the support base.

[0009] Preferred technical solution 2: A rotating block is provided at the end of the drive screw, a drive screw sleeve is sleeved on the drive screw, and an abutting clamping plate is fixed at the top of the drive screw sleeve. The side of the abutting clamping plate abuts against the side of the directional noise monitor.

[0010] Preferred technical solution 3: A handle is provided at the top of the top cover plate.

[0011] This solution makes it easier for users to lift the top cover.

[0012] Preferred technical solution four: A rubber pad is provided between the directional noise monitor and the support base.

[0013] This design allows the directional noise monitor to be placed more stably in the support base, with the rubber pad providing a certain cushioning effect.

[0014] Preferred technical solution five: The longitudinal section of both the driving screw sleeve and the driving groove is rectangular.

[0015] This design enables the drive sleeve to move more stably in the drive groove, preventing it from rotating with the drive screw.

[0016] Compared with the prior art, this utility model provides a portable directional noise monitor with the following advantages: This utility model features a portable protective component and a fixing clamping component on a support base. The two abutting clamping plates in the fixing clamping component, driven by a drive screw, fix the directional noise monitor to the top of the support base. The support rod, first connecting plate, and second connecting plate in the portable protective component work together to provide effective protection for the directional noise monitor. Users can quickly expose and use the directional noise monitor by pulling up the top cover, without needing to remove and install it. The casters at the bottom of the support base facilitate movement of the device. Furthermore, the overall structure of the device is compact and lightweight, making it more convenient for users to monitor outdoor non-fixed sound sources. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A portable directional noise monitor includes a support base 1, a portable protective component 2 is provided on the top of the support base 1, a directional noise monitor 4 is also provided on the support base 1, two fixing clamping components 3 are symmetrically arranged on both sides of the directional noise monitor 4, and movable wheels 5 are evenly installed around the bottom of the support base 1.

[0026] The portable protective component 2 includes a support rod 201 vertically arranged around the top of the support base 1. A first mounting groove 202 is provided on one side of the support rod 201, and a second mounting groove 203 is provided on the other side of the support rod 201. A limiting sliding groove 204 is provided on the side wall of the second mounting groove 203. A top cover plate 205 is provided on the top of the support base 1, and two first connecting plates 206 are symmetrically fixed on both sides of the bottom end of the top cover plate 205.

[0027] Two second connecting plates 207 are symmetrically fixed on the two outer sides of the bottom end of the top cover plate 205. The first connecting plate 206 is slidably inserted into the first mounting groove 202, and the second connecting plate 207 is slidably inserted into the second mounting groove 203. Two connecting screws 208 are symmetrically fixed at the ends of the two sides of the second connecting plate 207. The connecting screws 208 all pass through the limiting sliding groove 204, and the ends of the connecting screws 208 are fitted with fixing nuts 209.

[0028] The fixed clamping assembly 3 includes drive grooves 301 symmetrically opened on both sides of the top of the support base 1. A drive screw 302 is rotatably installed in each drive groove 301. The end of the drive screw 302 rotatably extends through the drive groove 301 to the outside of the support base 1. A rotating block 303 is provided at the end of the drive screw 302. A drive screw sleeve 304 is sleeved on the drive screw 302. An abutting clamping plate 305 is fixed at the top of the drive screw sleeve 304. The side of the abutting clamping plate 305 abuts against the side of the directional noise monitor 4.

[0029] Example 2: The difference between this example and Example 1 is that a handle is provided at the top of the top cover plate 205.

[0030] This makes it easier for users to lift the top cover 205.

[0031] Example 3: The difference between this example and Example 1 is that a rubber pad is provided between the directional noise monitor 4 and the support base 1.

[0032] This makes the directional noise monitor 4 more stable in the support base 1, and the rubber pad provides a certain buffering effect.

[0033] Example 4: The difference between this example and Example 1 is that the longitudinal sections of both the drive screw sleeve 304 and the drive groove 301 are rectangular.

[0034] This makes the drive sleeve 304 move more stably in the drive groove 301 and will not rotate with the drive screw 302.

[0035] In this embodiment, since most existing traditional noise monitoring methods rely on fixed monitoring stations or fixed equipment, these devices can continuously monitor fixed sound sources in a long-term and stable manner. However, they are not applicable to monitoring non-fixed sound sources for sudden noise in cities, and have obvious limitations.

[0036] In summary, in specific implementation, by setting a fixing clamping assembly 3 on the support base 1, the rotating block 303 in the fixing clamping assembly 3 drives the drive screw 302 to rotate, so that the drive screw sleeve 304 sleeved on the drive screw 302 can drive the abutting clamping plate 305 to abut against both sides of the directional noise monitor 4 placed on the top of the support base 1. Through the abutting of the two abutting clamping plates 305, the directional noise monitor 4 can be stably fixed on the support base 1.

[0037] A portable protective assembly 2 is also provided on the support base 1. The support rods 201 in the portable protective assembly 2 are vertically fixed around the top of the support base 1. A first mounting groove 202 is provided on one side of the support rod 201, and a second mounting groove 203 is provided on the other side. A limiting sliding groove 204 is provided on the inner wall of the second mounting groove 203, and the top side of the limiting sliding groove 204 is open. A top cover plate 205 is provided on the top of the support rod 201. Two first connecting plates 206 are symmetrically arranged on both sides of the bottom end of the top cover plate 205. The first connecting plates 206 can be inserted into the first mounting groove 202, and the second connecting plates 207 can be inserted into the second mounting groove 203. Thus, the support rods 201, the first connecting plates 206 and the second connecting plates 207 can form a protective cover for the outside of the directional noise monitor 4. With the cooperation of the support base 1, the directional noise monitor 4 can be enclosed.

[0038] When using the directional noise monitor 4, the bottom of the support base 1 is equipped with casters 5, which makes the movement of the device more convenient. When the directional noise monitor 4 reaches the designated location, the user can directly pull up the top cover 205 and rotate the fixing nut 209 on the connecting screw 208 that is slidably inserted in the limiting slot 204 to expose the directional noise monitor 4 for monitoring environmental noise. There is no need to remove the directional noise monitor 4, making the operation faster and more convenient. In addition, the overall structure of the device is small and lightweight, making it more convenient for users to monitor outdoor non-fixed sound sources.
