Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

Referring to fig. 1-3, a ventilation air conditioner noise reduction device, including shell 1, shell 1 lateral wall fixedly connected with air pipe 4, shell 1 top and the equal fixedly connected with otic placode 2 in bottom, fixing bolt 3 has been pegged graft to otic placode 2 top surface, otic placode 2 passes through fixing bolt 3 and air pipe 4 fixed connection, because shell 1 and air pipe 4 are all made by the metal, in order to avoid appearing colliding with between the two and make the sound, be provided with rubber pad 14 between shell 1 and the air pipe 4, and rubber pad 14 and shell 1 fixed connection, shell 1 keeps away from one side of air pipe 4 and has seted up a plurality of exhaust vents 5.

Referring to fig. 2-4, the inner side wall of the shell 1 is provided with a shockproof pad 6, the shockproof pad 6 is a melamine foam board, and the melamine foam board can effectively prevent and reduce noise generated by the noise reduction parts in the shell 1 during working; the 6 inner walls of antivibration pad are provided with installing frame 7, and installing frame 7 is the setting of C type, and 7 inner wall joints of installing frame have a plurality of

acoustical panel

11, and 7 inside wall fixedly connected with multiunit of installing frame and 11 complex clamp splice 10 of acoustical panel, 11 lateral walls of acoustical panel slide and peg graft inside clamp splice 10, and inside user of service can insert clamp splice 10 with acoustical panel 11 from 7 breachs of installing frame.

7 tops of installing frame are provided with bounding

wall

8, and 8 tops of bounding wall are pegged graft and are had connecting bolt 9, and installing frame 7 passes through connecting bolt 9 and 8 fixed connection of bounding wall, and the user of service can install bounding wall 8 in the breach department of installing frame 7 through connecting bolt 9, and acoustical panel 11 will be stabilized the joint inside installing frame 7 this moment.

Because the crash pad 6 has a certain elasticity and is easy to deform, in order to facilitate a user to insert the mounting frame 7 and the coaming 8 into the crash pad 6, the side surfaces of the mounting frame 7 and the coaming 8, which are close to the shell 1, are both obliquely arranged.

A plurality of through holes are formed in the side wall of each sound-absorbing plate 11, the through holes of the adjacent sound-absorbing plates 11 are arranged in a staggered mode, the sound-absorbing plates 11 are fixedly connected with a plurality of sound-absorbing pipes 12 communicated with the through holes, the sound-absorbing pipes 12 are micro ceramic pipes, the sound-absorbing pipes 12 are arranged in a frustum mode, sound-absorbing cotton 13 is fixedly connected to the inner walls of the sound-absorbing pipes 12, when sound enters the sound-absorbing pipes 12 on the surfaces of the sound-absorbing plates 11, the sound-absorbing pipes 12 can be separated and part of sound waves can be changed, the sound waves collide with each other to offset part of energy, the sound waves can be absorbed by the sound-absorbing cotton 13 in the process of being transmitted out of the sound-absorbing pipes 12, and due to the fact that the sound-absorbing pipes 12 on the different sound-absorbing plates 11 are arranged in a staggered mode, the sound waves can collide with the sound-absorbing pipes 11 to lose part of energy, and noise is reduced effectively.
