Detailed Implementation

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0013] like Figure 1-3 As shown, the substation noise reduction and ventilation integrated equipment includes a ventilator 1. The ventilator 1 is equipped with polyurethane foam 2, a connecting flange 3, a connecting seat 4, and a mounting slot 5. The polyurethane foam 2 fills the hollow cavity of the ventilator 1. The connecting flange 3 is symmetrically welded to both ends of the ventilator 1, and a duct silencer 6 is bolted to the outer end of the connecting flange 3. The connecting seat 4 is symmetrically welded to the front and rear ends of the ventilator 1, and a connecting shaft 7 is welded to the top of the connecting seat 4. A mounting seat 8 is welded to the top of the connecting shaft 7, and a shock-absorbing rubber seat 9 is placed on the top of the mounting seat 8. The mounting slot 5 is located at the top of the middle section of the ventilator 1, and a first mounting platform 10 and a cover 11 are provided on the mounting slot 5. The first mounting platform 10 is symmetrically welded to both sides of the bottom of the mounting slot 5. The cover 11 is placed on the mounting slot 5. The cover 11 is provided with a second mounting platform 12, a limiting block 13 and a shock-absorbing rubber sleeve 14. The second mounting platform 12 is symmetrically welded to both sides of the bottom of the cover 11 and is fixedly connected to the first mounting platform 10 by bolts. The limiting block 13 is integrally formed and connected to the top middle of the inner side of the cover 11. The shock-absorbing rubber sleeve 14 is nested inside the cover 11. The shock-absorbing rubber sleeve 14 is provided with a limiting groove 15 and a ventilation fan 16. The limiting groove 15 is opened in the top middle of the shock-absorbing rubber sleeve 14 and is fitted onto the limiting block 13. The ventilation fan 16 is interference-fitted into the inside of the shock-absorbing rubber sleeve 14.

[0014] Specific usage: The ventilator 1 is installed and fixed in the designated position using the mounting base 8. At the same time, the shock-absorbing rubber seat 9 on the top of the mounting base 8 can easily buffer the vibration generated by the main body of the ventilator 1, reducing noise generation. The outer end of the connecting flange 3 is fixed with a duct silencer 6 by bolts, which can reduce noise at the air inlet and outlet of the ventilator 1. The ventilation fan 16 is interference-fitted into the inside of the shock-absorbing rubber sleeve 14, which can buffer the vibration generated by the ventilation fan 16 during operation, reducing noise generation. The polyurethane foam 2 is filled into the hollow cavity of the ventilator 1, which can block the noise inside the ventilator 1.
