[0002] Electromechanical equipment generally refers to machinery, electrical appliances and electrical automation equipment. In construction, it mostly refers to the general term for machinery and piping equipment other than geotechnical, carpentry, steel bars and mud and water equipment. It is different from hardware and mostly refers to finished products that can achieve certain functions. Since electromechanical equipment will generate a lot of noise during operation, especially electric motors, they will generate noise when running, so they need to be subjected to noise reduction treatment.

[0003] Existing silencers are mainly composed of upper and lower end covers and a middle layer of microporous metal mesh. To ensure the sound-absorbing effect, this metal mesh is generally made relatively thin. As a result, it is very easy to deform due to the vibration of electromechanical equipment and other external forces during long-term use.

[0004] After long-term use, the sound insulation board or sound insulation cotton is covered with dust. Currently, a box made of sound insulation cotton or sound insulation board is used to cover the electromechanical equipment to reduce the occurrence of noise. The connection method used is bolt connection, which is not convenient for replacing and cleaning the sound insulation board or sound insulation cotton.

[0005] Therefore, the present invention designs a silencing device for electromechanical equipment to solve the technical problems existing in the prior art. Utility Model Content

[0024] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figure 1-5The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0025] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] Embodiment 1, a silencing device for electromechanical equipment, comprising a silencing body 1, a silencing cover 2, and a motor 3, is characterized by:

[0027] The muffler body 1 is fixedly connected with four groups of main support plates 4 at intervals along the circumferential direction. The muffler body 1 is slidably connected with two groups of mounting plates 5 corresponding to the main support plates 4. A retractable plate 6 is provided between the two groups of mounting plates 5 and the main support plates 4.

[0028] The two groups of mounting plates 5 are provided with mounting grooves 7, and adjacent mounting grooves 7 located on the same horizontal plane are provided with sound insulation boards 8;

[0029] The four groups of main support plates 4 are provided with guide grooves 9, the muffler cover 2 is provided with guide blocks 10 that cooperate with the guide grooves 9, the guide blocks 10 are provided with positioning holes 11, the four groups of main support plates 4 are slidably connected with positioning handles 12, a return spring 13 is provided between the positioning handles 12 and the main support plates 4, and the positioning handles 12 are provided with positioning columns 14 corresponding to the positioning holes 11;

[0030] The motor 3 is located between the silencer body 1 and the silencer cover 2. Ventilation holes 15 are provided on the silencer body 1 and the silencer cover 2.

[0031] When in use, first separate the silencer body 1 from the silencer cover 2, install the motor 3 to the bottom of the silencer body 1, so that the motor 3 is fixedly connected to the bottom plate of the silencer body 1; place the sound insulation board 8 into the two sets of mounting grooves 7 on the same horizontal plane, and then pass the silencer cover 2 through the output shaft of the motor 3 to match it with the silencer body 1;
