Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 As shown, a vertical noise detector includes a noise detection device body 1 and a mounting base 2, the mounting base 2 is located below the noise detection device body 1, and the four corners of the surface of the mounting base 2 are provided with screw holes for fixing the detector, a support platform 3 is arranged above the mounting base 2, and a box body 4 is fixed to the bottom of the support platform 3, and an adjustment structure 5 for adjusting the installation angle of the detector is arranged inside the box body 4, the adjustment structure 5 includes a threaded rod 54 and a movable sleeve 55, the movable sleeve 55 is hinged on the left and right sides of the top of the mounting base 2, the threaded rod 54 is arranged above the movable sleeve 55, and the threaded rod 54 is threadedly connected to the inner wall of the movable sleeve 55, the top of the support platform 3 is bolted with a fixed shell 6, and the interior of the fixed shell 6 is provided with a transfer structure 7 for adjusting the direction of the detector, the top of the fixed shell 6 is penetrated with an adjustment support rod 8, the adjustment support rod 8 is a telescopic rod, and the upper half of the adjustment support rod 8 is bolted to one side of the noise detection device body 1.

[0023] The adjustment structure 5 also includes a first motor 51, a double-groove pulley 52, and a single-groove pulley 53. The first motor 51 is fixed to the bottom of the box body 4, and the double-groove pulley 52 is rotatably connected to the top of the inner wall of the box body 4. The output shaft of the first motor 51 passes through the interior of the box body 4 and is fixedly connected to the bottom of the double-groove pulley 52. ​​The single-groove pulley 53 is arranged on the left and right sides of the interior of the box body 4, and the single-groove pulley 53 is connected to the double-groove pulley 52 through a belt. The top end of the threaded rod 54 passes through the interior of the box body 4 and rotates with the inner wall of the box body 4. The threaded rod 54 passes through the single-groove pulley 53 and is fixedly connected to the single-groove pulley 53. The thread directions of the threaded rods 54 on the left and right sides of the box body 4 are opposite. When the first motor 51 is turned on, the double-groove pulley 52 drives the single-groove pulleys 53 on both sides to rotate in the same direction through the belt, and the threaded rods 54 on both sides rotate. Due to the different thread directions of the threaded rods 54 on both sides, the movable sleeve 55 on one side rises, while the movable sleeve 55 on the other side falls, thereby causing the mounting base 2 below to tilt.

[0024] Limiting rods 9 are fixed on both the left and right sides of the box body 4, a limiting groove 10 is provided on the surface of one side of the movable sleeve 55, and one end of the limiting rod 9 extends to the inside of the limiting groove 10 and is slidably connected to the inner wall of the limiting groove 10. When the threaded rod 54 rotates, the limiting rod 9 on one side will limit the movable sleeve 55, so that the movable sleeve 55 can only move in the up and down directions, so as to adjust the inclination angle of the mounting base 2.

[0025] The indexing structure 7 includes a second motor 71, a first timing pulley 72 and a second timing pulley 73. The second motor 71 is fixed to the right side of the top of the fixed shell 6. The first timing pulley 72 and the second timing pulley 73 are rotatably connected to the middle part of the fixed shell 6 and the right side of the fixed shell 6 respectively. The output shaft of the second motor 71 passes through the fixed shell 6 and is fixedly connected to the top of the first timing pulley 72. The surfaces of the first timing pulley 72 and the second timing pulley 73 are both sleeved with timing belts. The first timing pulley 72 and the second timing pulley 73 are connected by timing belt transmission. The bottom end of the support rod 8 is fixedly connected to the top of the second timing pulley 73. The diameter of the first timing pulley 72 is smaller than that of the second timing pulley 73. After the staff turns on the second motor 71, the first timing pulley 72 below can drive the second timing pulley 73 to rotate through the timing belt, thereby causing the upper adjustment support rod 8 to rotate. The diameter of the first timing pulley 72 is smaller than that of the second timing pulley 73, so that the second timing pulley 73 can rotate slowly, and the orientation of the noise detection device body 1 can be fine-tuned so that the noise detection device body 1 accurately faces the noise generating position.

[0026] Working principle: When the staff needs to perform noise detection, the staff first moves the detector to the detection area, and then the staff turns on the first motor 51 below. The staff controls the rotation direction of the output shaft of the first motor 51 according to the installation position, so that the mounting base 2 below is tilted. After adjusting the mounting base 2 to a suitable angle, the staff can take out the bolts and install and fix the detector through the screw holes on the surface of the mounting base 2. After the fixation is completed, the staff can turn on the second motor 71, control the rotation direction of the output shaft of the second motor 71, and adjust the direction of the noise detection device body 1 according to the noise emission position. After adjusting the direction of the noise detection device body 1, the staff turns off the second motor 71 to complete the installation of the noise detector.
