Description

Technical Field

[0001] This application relates to the field of noise monitoring, and in particular to a noise extension rod. Background Technology

[0002] Common noise monitoring indicators include: noise intensity, i.e., sound pressure in the sound field; and noise characteristics, i.e., the various frequency components of the sound pressure. Noise measurement instruments mainly include: sound level meters, frequency analyzers, real-time analyzers, sound intensity analyzers, noise level analyzers, noise dosimeters, automatic recorders, and magnetic tape recorders.

[0003] Currently, in the field of noise monitoring, it can detect noise in a relatively close range, but its overall function is limited. It cannot accurately locate noise 0.5 meters above the wall or extend to one meter outside the factory boundary. In addition, various angles need to be adjusted during actual operation, but the current monitoring devices cannot adjust the angles, making accurate quantification impossible and reducing the effectiveness of noise monitoring. Utility Model Content

The sensor seat 13 can be used to place a sensor, and multiple claws 14 are connected to the sensor seat 13 by a torsion spring, arranged evenly in a circle. A limiting groove 11 is formed on the inner side of the limiting head 9, and a limiting strip 12 is provided on the side of the moving rod 10. The width of the limiting groove 11 and the width of the limiting strip 12 are matched. The limiting strip 12 is located inside the limiting groove 11 and can move inside the limiting groove 11. Inside the section cylinder 8, a push column 15 is installed. One end of the push column 15 is rotatably connected to the other end of the moving rod 10. The other end of the adjusting cylinder 8 is equipped with a threaded sleeve 16. The push column 15 is provided with an adjusting thread 17 that is adapted to the threaded sleeve 16. The push column 15 is located inside the threaded sleeve 16 and is connected to the threaded sleeve 16 through the adjusting thread 17. The push column 15 can be rotated. When the push column 15 rotates, it can cooperate with the threaded sleeve 16 through the adjusting thread 17, and one end moves gradually, pushing the moving rod 10 to move. The moving rod 10 can move gradually through the cooperation of the limiting strip 12 and the limiting groove 11, driving the sensor at one end to move and adjusting its extended length.

[0031] Please refer to Figure 1 , Figure 2 and Figure 5 A connector rod 18 is installed in the lower middle part of the adjusting cylinder 8, and a fastener 19 is installed in the upper part of the center rod 1. The lower end of the connector rod 18 is inserted into the interior of the fastener 19, and a fastening bolt 20 is installed at one end of the fastener 19. A second positioning bolt 21 is also installed on the fastener 19. One end of the second positioning bolt 21 abuts against the side of the center rod 1. Loosen the fastening bolt 20, and then rotate the adjusting cylinder 8 and the connector rod 18 so that the sensor seat 13 at one end of the adjusting cylinder 8 moves around the connector rod 18, thereby moving the sensor and adjusting the left and right angles of the sensor.

[0032] Please refer to Figure 1 and Figure 2 A mounting platform 2 is provided in the middle of the central rod 1. A support foot 3 is movably mounted on the side of the mounting platform 2.

The height and range of the support can be adjusted via the telescopic rod 4 inside the support feet 3, making the overall structure more stable. Then, rotate the first positioning bolt 6 to separate one end of the first positioning bolt 6 from the side of the central rod 1. At this time, the height of the central rod 1 can be adjusted up and down. When the central rod 1 moves up and down, the height of the upper adjusting cylinder 8 and the sensor base 13 can be adjusted to achieve the purpose of height adjustment. After adjusting to a suitable height, the first positioning bolt 6... The center rod 1 can be fixed. When the angle of the sensor needs to be adjusted, the fastening bolt 20 can be loosened, and then the adjusting cylinder 8 and the plug rod 18 can be rotated so that the sensor seat 13 at one end of the adjusting cylinder 8 moves around the plug rod 18, thereby moving the sensor and adjusting the left and right angles of the sensor. Then, the push column 15 can be rotated. When the push column 15 rotates, it can move one end gradually through the engagement of the adjusting thread 17 and the threaded sleeve 16, pushing the moving rod 10 to move. The moving rod 10 can move gradually through the engagement of the limiting strip 12 and the limiting groove 11, thereby moving the sensor at one end and adjusting its extension length.
