The beneficial effects of the utility model are:
It arranges strengthening sleeve and interior strengthening sleeve at air duct outer wall, thus improves its intensity, simultaneously, the diatom mud layer that it has has sound absorption, has certain noise reduction, thus when reducing roof ventilator operation, the spread scope of its noise, ensure that the normal life of people.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Embodiment: as shown in Figure 1, high strength roof axial fan, comprise blast cap 1, air duct 2, base 3 and mair motor 4, be arranged at bottom described air duct 2 on described base 3, air duct 2 top is provided with described blast cap 1, and it is inner that described mair motor 4 is arranged at air duct 2, the end winding support of the coupling shaft 7 of mair motor 4 has impeller 6, described air duct 2 bottom extends downwardly through the top board of base 3, and the bottom of air duct 2 is fixed with safety check 8, and the bottom of air duct 2 is fixed with safety net 9;
The outer wall cover of described air duct 2 has strengthening sleeve 21, strengthening sleeve 21 is bolted to connection on the base 3, undulatory interior strengthening sleeve 22 is inserted with in strengthening sleeve 21, interior strengthening sleeve 22 is between strengthening sleeve 21 and air duct 2, granular porous particle 23 is filled with in cavity between strengthening sleeve 21 and air duct 2, strengthening sleeve 21 is bolted with end cap 24, end cap 24 sleeve is in air duct 2.
Granular porous particle 23 can be that plastic material, glass wool or other porous material are all passable.
Further, in the annular groove 251 that the top sleeve of described air duct 2 has in the bottom surface of top strengthening sleeve 25, the middle part of top strengthening sleeve 25 has vertically cover 252, vertical cover 252 sleeve is in air duct 2, the outer wall of vertical cover 252 is close to the madial wall of air duct 2, the edge of top strengthening sleeve 25 has radial extension joint 253, and blast cap 1 is fixed on radial extension on joint 253 by connecting rod 11.
