The slider 34 is slidably connected in the slide groove 341. A mounting groove 33 is provided in the slide groove 341. The second spring 36 is installed in the mounting groove 33.

[0048] Further, such as Figure 5 As shown, a positioning groove 371 is axially provided on the inner wall of the fixing cylinder 31 , and a positioning block 37 which can slidably cooperate with the positioning groove 371 is provided on the outer wall of the adjusting rod 32 .

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the detection component includes a microphone 42, a connector 4, a data processing component 6 and an LED display screen 5, and the LED display screen 5 is installed on the extension part of the lifting and adjusting component 3. Specifically, in this embodiment, the LED display screen 5 is fixedly installed on the outer wall of the adjusting rod 32 exposed above the fixed cylinder 31. The top of the adjusting rod 32 is connected to the data processing component 6, and the top of the data processing component 6 is detachably connected to the microphone 42 through the connector 4, and the microphone 42 is electrically connected to the data processing component 6.

[0050] Further, such as Figure 6 and Figure 7 As shown, the connecting member 4 includes a bracket 41 and a connecting block 43. The top of the data processing component 6 is connected to the bracket 41, and the top of the bracket 41 is provided with a threaded groove 431. The bottom of the microphone 42 is connected to the connecting block 43, and the outer wall of the connecting block 43 is provided with an external thread that can be threadedly matched with the threaded groove 431.

[0051] The implementation principle of a rail transit noise detection device is as follows:

[0052] First, a base groove that can be matched with the base 1 is opened in the area to be installed, and a wedge-shaped groove matched with the wedge block 23 is provided in the base groove. Then, the base 1 is inserted into the base groove in the area to be installed. The wedge block 23 is squeezed during the downward movement, so that the two wedge blocks 23 move toward the base 1. Under the transmission of the movable plate 22, the first spring 26 is compressed until the wedge block 23 moves down into the wedge-shaped groove. Under the elastic force of the first spring 26, the wedge block 23 pops out and engages with the wedge groove, thereby completing the quick installation between the base 1 and the base groove.

[0053] When the height of the microphone 42 is adjusted, the block 35 is squeezed inwardly, and the second spring 36 is compressed under the drive of the slider 34, so that the block 35 is pressed into the adjustment rod 32. At this time, the position of the adjustment rod 32 can be pulled up and down. When the adjustment rod 32 is in a suitable position, the block 35 is ejected and engaged in the through hole 351 on the fixed tube 31 under the elastic force of the second spring 36, so as to realize the detection height adjustment of the microphone 42.

[0054] At the same time, the sliding cooperation between the positioning block 37 and the positioning groove 371 can improve the stability of the lifting and lowering adjustment between the fixing tube 31 and the adjusting rod 32 .

[0055] The microphone 42 is installed by rotating the connection block 43 at the bottom of the microphone 42 to the top of the bracket 41 until the external thread on the connection block 43 is engaged with the thread groove 431 at the top of the bracket 41. When the microphone 42 needs to be replaced, the microphone 42 is rotated in the opposite direction until the connection block 43 is separated from the bracket 41, and the microphone 42 can be removed for replacement.

[0056] The noise around the track is detected by the microphone 42, and the sound wave signal is converted into an electrical signal. The data acquisition module receives the electrical signal from the microphone 42, and performs amplification, filtering, and digital-to-analog conversion to convert the electrical signal into a digital signal. The data transmission module transmits the noise data from the data acquisition module to the remote monitoring center, so that the monitoring personnel can view and analyze the noise data at a remote location.
