[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] See also Figures 1 to 7 , the utility model provides a technical solution:

[0028] An automatic environmental noise analysis device comprises a base plate 1, a shell 2 is fixedly mounted on the upper end surface of the base plate 1, universal wheels 3 are fixedly mounted at the four corners of the lower end surface of the base plate 1, a push plate 4 is arranged on the upper side of the shell 2, a noise detector 5 is fixedly mounted on the upper end surface of the push plate 4, a dual-axis motor 6 is fixedly mounted on the inner lower end surface of the shell 2, a threaded rod 8 is fixedly mounted on the end of the right output shaft of the dual-axis motor 6, the other end of the threaded rod 8 is rotatably connected to a support member 7, the support member 7 is fixedly connected to the inner wall of the shell 2, a threaded sleeve 9 is spirally connected to the outer surface of the threaded sleeve 9, a connecting rod 10 is rotatably connected to the upper end of the threaded sleeve 9, an extrusion plate 12 is arranged on the inner upper side of the shell 2, a connecting block 11 is fixedly mounted on the lower end surface of the extrusion plate 12, and the connecting rod 10 is rotatably connected to the connecting block 11.

[0029] The threaded rod 8 , the threaded sleeve 9 and the connecting rod 10 are respectively provided in two groups and are symmetrically arranged, and the two groups of connecting rods 10 are rotatably connected to the connecting block 11 .

[0030] A push rod 13 is fixedly mounted on the upper end surface of the extrusion plate 12 . The push rod 13 extends to the upper side of the housing 2 and is fixedly connected to the push plate 4 .

[0031] When it is necessary to detect different noises, the dual-axis motor 6 is started to drive the two groups of threaded rods 8 to rotate respectively, and the threaded sleeve 9 connected to the spiral transmission on the outer surface of the threaded rod 8 will carry the connecting rod 10 to move, and the two groups of connecting rods 10 are synchronously connected to the connecting block 11 on the extrusion plate 12 for rotation. Therefore, the two groups of threaded sleeves 9 are displaced toward each other, which will drive the extrusion plate 12 to rise, and drive the noise detector 5 on the push plate 4 to adjust the height through the push rod 13.

[0032] A sleeve 14 is fixedly mounted on the inner upper end surface of the housing 2 , and the extrusion plate 12 is slidably connected inside the sleeve 14 .

[0033] An air bag 15 is fixedly installed inside the sleeve 14 , and an input port is communicated with the outer surface of the air bag 15 .

[0034] An annular tube 16 is provided on the outer side of the noise detector 5 , and the annular tube 16 is fixedly connected to the push plate 4 .

[0035] A connecting pipe 17 is provided between the air bag 15 and the annular tube 16 . A nozzle 18 is provided on the outer surface of the annular tube 16 . The nozzle 18 is arranged in an inclined manner.

[0036] When the extrusion plate 12 rises, it will squeeze the airbag 15, so that the gas inside the airbag 15 enters the ring pipe 16 through the connecting pipe 17 and is sprayed toward the noise detector 5 through the nozzle 18 to clean the dust on its outer surface.

[0037] A threaded rod 2 19 is fixedly installed at the end of the threaded rod 1 8, and a threaded sleeve 20 is spirally connected to the outer surface of the threaded rod 19. A limiting member 21 is slidably connected to the outer surface of the threaded sleeve 20. The limiting member 21 is fixedly connected to the base plate 1, and a universal wheel 22 is fixedly installed at the end of the threaded sleeve 20.

[0038] The rotation of the threaded rod 1 8 drives the threaded rod 2 19 to rotate, and the threaded sleeve 20 connected to the outer surface of the threaded rod 2 19 by a spiral transmission will move outward and drive the universal wheel 2 22 to move outward, thereby increasing the stability of the bottom of the equipment and preventing it from tipping over.

[0039] The utility model provides a universal wheel 22. As the height of the noise detector 5 is gradually increased, the universal wheel 22 extends outwardly longer, thereby improving the stability of the device. At the same time, the airbag 15 and the nozzle 18 can clean the dust on the outer surface of the noise monitor.

[0040] The existing noise monitoring equipment has a relatively simple design structure, and most of them adopt a fixed integrated structure design. The noise monitoring equipment with this fixed integrated design has good overall stability. However, when monitoring the noise in the environment, it is impossible to monitor noise in different directions, resulting in a limited range of noise monitoring by the noise monitoring device. Therefore, the utility model sets a threaded rod, a threaded sleeve 9 and a connecting rod 10, so that the noise detector 5 can perform real-time monitoring of noise at different heights, adapt to different operating requirements, and improve the practicability of the equipment.

[0041] Working principle: when it is necessary to detect different noises, by starting the dual-axis motor 6, the two groups of threaded rods 8 are driven to rotate respectively, and the threaded sleeve 9 connected to the outer surface of the threaded rod 8 by the spiral transmission will carry the connecting rod 10 to move, and the two groups of connecting rods 10 are synchronously connected to the connecting block 11 on the extrusion plate 12. Therefore, the displacement of the two groups of threaded sleeves 9 towards each other will drive the extrusion plate 12 to rise, and drive the noise detector 5 on the push plate 4 to adjust the height through the push rod 13. When the extrusion plate 12 rises, the airbag 15 will be squeezed, so that the gas inside the airbag 15 enters the annular tube 16 through the connecting pipe 17, and is sprayed to the noise detector 5 through the nozzle 18 to clean the dust on its outer surface. The rotation of the threaded rod 8 will drive the threaded rod 2 19 to rotate, and the threaded sleeve 20 connected to the outer surface of the threaded rod 2 19 by the spiral transmission will move outward, and drive the universal wheel 2 22 to move outward, thereby increasing the stability of the bottom of the equipment and preventing it from tipping over.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
