Description

Technical Field

[0001] This utility model relates to the field of noise monitoring vehicle technology, and in particular to a mobile noise monitoring vehicle. Background Technology

[0002] A mobile noise monitoring vehicle is a specialized mobile device for noise monitoring. It can operate in various scenarios, such as roads and cities, to monitor noise levels from different sources in real time, thereby understanding the generation, distribution, and changes in noise. Compared with other noise monitoring equipment, mobile noise monitoring vehicles have the following advantages: 1. Comprehensive and continuous noise monitoring: Using a mobile monitoring method, mobile noise monitoring vehicles can travel on roads or in cities, conducting comprehensive monitoring of both noise sources and the environmental background, thus obtaining more comprehensive and accurate monitoring data. 2. Monitoring at multiple locations: Mobile noise monitoring vehicles can monitor noise at multiple locations, such as different streets, road sections, roads, and intersections, allowing for comparative analysis of noise data from different locations and effectively diagnosing the problem.

[0003] Current mobile noise monitoring vehicles mainly install noise monitoring devices on the roof, making it convenient to monitor noise while the vehicle is in motion. However, existing noise monitoring devices are usually directly exposed on the roof, which makes it inconvenient to collect noise when it rains. This is mainly because raindrops falling on the receiver can cause interference and damage to the receiver. In addition, when monitoring is not needed, dust in the air can easily accumulate on the receiver, affecting its subsequent use. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose a mobile noise monitoring vehicle. The technical problem to be solved is that existing noise monitoring instruments are usually directly exposed and installed on the roof of the vehicle. It is inconvenient to collect noise when it rains, mainly because raindrops falling on the receiver can easily cause interference and rain can also easily damage the receiver. In addition, when monitoring is not needed, dust in the air can easily accumulate on the receiver, thus affecting the subsequent use of the receiver.

[0006] (2) Technical solution

[0007] To achieve the above technical objectives, this utility model provides a mobile noise monitoring vehicle:

[0008] It includes a main unit and a lifting unit. The main unit includes a mobile vehicle body, a mounting base fixed on the roof of the mobile vehicle body, a baffle above the mounting base, a cover fixed to the outside of the baffle, a noise monitoring instrument mounted at the bottom of the baffle, and a microphone mounted on the noise monitoring instrument. The lifting unit includes a support column fixed to the mounting base, multiple vertical rods fixed at equal intervals at the bottom of the baffle, a horizontal rod fixed to the bottom of the vertical rods, and a control component for controlling the lifting of the noise monitoring instrument and the microphone inside the support column.

[0009] Preferably, the support column has a stroke groove in the middle, and multiple guide grooves are equally spaced inside the support column, with the guide grooves and stroke grooves connected. The crossbar is slidably fitted inside the guide groove.

[0010] Preferably, the control component includes an inner cavity opened at the top of the support column, a servo motor installed in the inner cavity, a screw rotatably connected in the stroke groove, and the top of the screw being fixed to the output end of the servo motor. A threaded sleeve is threadedly connected to the outside of the screw, and the threaded sleeve is slidably fitted in the stroke groove. The end of the crossbar away from the vertical bar is fixed to the threaded sleeve, and a sealing cap is plugged on the inner cavity.

[0011] Preferably, an annular sleeve is fixed to the bottom of the baffle, and an annular plate is fixed to the outer side of the top of the support column, wherein the diameter of the annular sleeve is smaller than the diameter of the annular plate.

[0012] Preferably, the axes of the annular sleeve, annular plate, stroke groove, screw, and threaded sleeve coincide.

[0013] Preferably, sound-absorbing cotton is fixed to the top of the baffle and the cover.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. When noise monitoring is needed on a rainy day, start the servo motor to drive the screw to rotate, which in turn moves the threaded sleeve, horizontal bar, vertical bar, baffle, and ring sleeve upward. When the ring sleeve moves upward, the noise monitoring instrument and microphone are exposed, and noise monitoring can be carried out. In addition, the sound of raindrops falling on the sound-absorbing cotton is absorbed by the sound-absorbing cotton, which avoids the sound of raindrops falling directly on the microphone and interfering with the sound recording, and also avoids rainwater damaging the microphone.

[0016] 2: When noise monitoring is not required, start the servo motor to drive the screw to rotate in the opposite direction, thereby moving the threaded sleeve, horizontal bar, vertical bar, baffle, annular sleeve, noise monitor, and microphone downwards until the annular sleeve and annular plate are in contact. Then turn off the servo motor. At this time, the noise monitor and microphone are located between the annular plate and the annular sleeve. Since the annular sleeve and annular plate are in a sealed space, dust in the air is prevented from falling onto the microphone and causing blockage. Attached Figure Description

[0022] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure.

[0023] Reference Figure 1-3 :

[0024] In one embodiment of this utility model, a mobile noise monitoring vehicle is provided, including a main unit 100 and a lifting unit 200. The main unit 100 includes a mobile vehicle body 101, a mounting base 102 fixed on the roof of the mobile vehicle body 101, a baffle 103 above the mounting base 102, a cover 104 fixed on the outside of the baffle 103, a noise monitoring instrument 105 installed at the bottom of the baffle 103, and a microphone 106 installed on the noise monitoring instrument 105. The lifting unit 200 includes a support column 201 fixed to the mounting base 102. Multiple vertical rods 202 are fixed at equal intervals at the bottom of the baffle 103, and a horizontal rod 203 is fixed at the bottom of the vertical rods 202. A control component for controlling the lifting of the noise monitoring instrument 105 and the microphone 106 is provided inside the support column 201.

[0025] Specifically, a stroke groove 213 is provided in the middle of the support column 201, and multiple guide grooves 204 are provided at equal intervals inside the support column 201. The guide grooves 204 and the stroke grooves 213 are connected. The crossbar 203 is slidably fitted in the guide grooves 204. The control component includes an inner cavity 205 opened at the top of the support column 201. A servo motor 206 is installed in the inner cavity 205. A screw 207 is rotatably connected in the stroke groove 213. The top of the screw 207 is fixed to the output end of the servo motor 206. A threaded sleeve 208 is threadedly connected to the outside of the screw 207. The threaded sleeve 208 is slidably fitted in the stroke groove 213. The end of the crossbar 203 away from the vertical bar 202 is fixed to the threaded sleeve 208. A sealing cap 209 is plugged on the inner cavity 205. Sound-absorbing cotton 212 is fixed on the top of the baffle 103 and the cover 104.

[0026] When noise monitoring is needed on a rainy day, the servo motor 206 is started to drive the screw 207 to rotate. When the screw 207 rotates, it drives the threaded sleeve 208 to move upward. When the threaded sleeve 208 moves upward, it drives the horizontal bar 203 and the vertical bar 202 to move upward, which in turn drives the baffle 103 to move upward. This, in turn, drives the annular sleeve 210, the noise monitor 105, and the microphone 106 to move upward. When the annular sleeve 210 moves upward, the noise monitor 105 and the microphone 106 are exposed, and noise monitoring can be performed. When raindrops fall on the sound-absorbing cotton 212, the sound of the raindrops is absorbed by the sound-absorbing cotton 212, which avoids the raindrops falling directly on the microphone 106 and causing interference to the sound reception, and also avoids the rainwater from damaging the microphone 106.

[0027] Furthermore, an annular sleeve 210 is fixed to the bottom of the baffle 103, and an annular plate 211 is fixed to the outer side of the top of the support column 201. The diameter of the annular sleeve 210 is smaller than the diameter of the annular plate 211, and the axes of the annular sleeve 210, the annular plate 211, the stroke groove 213, the screw 207, and the threaded sleeve 208 coincide.

[0028] When noise monitoring is not required, the servo motor 206 is started to drive the screw 207 to rotate in the opposite direction. This causes the screw 207 to move the threaded sleeve 208 downward. As the threaded sleeve 208 moves downward, it causes the horizontal bar 203, the vertical bar 202, and the baffle 103 to move downward. This, in turn, causes the annular sleeve 210, the noise monitor 105, and the microphone 106 to move downward until the annular sleeve 210 and the annular plate 211 are in contact. The servo motor 206 is then turned off. At this time, the noise monitor 105 and the microphone 106 are located between the annular plate 211 and the annular sleeve 210. Since the baffle 103, the annular sleeve 210, and the annular plate 211 form a sealed space, dust in the air is prevented from falling onto the microphone 106 and causing blockage.

[0029] It should be noted that the noise monitor 105, microphone 106, and servo motor 206 in this embodiment are all commercially available conventional devices known to those skilled in the art. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. Furthermore, the noise monitor 105, microphone 106, and servo motor 206 are all equipped with corresponding control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0030] The exemplary implementation schemes proposed in the present disclosure are described in detail above with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
