The kind of existing roof ventilator is a lot, as existing a kind of roof ventilator, comprise electric machine casing, impeller exhaust casing, column, slip ring base, motor and centrifugal impeller, centrifugal impeller comprises wheel plate and is arranged on the blade in wheel plate front, in wheel back, fin is installed, impeller exhaust casing is positioned at place above fin and is provided with radiation hole, electric machine casing is provided with ventilation rainproof blinds.The feature of this kind of roof ventilator effectively can solve heat dissipation problem.
Now also has a kind of roof ventilator, comprise rainhat, bird proof net, air duct, frame, base, installation foundation, air duct outlet port is provided with the bird proof net perpendicular to barrel, bird proof net is fixed by threaded stem and air duct outer wall, threaded stem is connected with bird proof net is vertical, rainhat is covered with above bird proof net and air duct, the joint of rainhat and threaded stem is provided with suspension ring, the support of air duct is frame, the bottom of frame is provided with connected base and installation foundation, the top of air duct is welded with waterproof flange, air duct and welding machine frame are integrated, base side is by fixing bolt and installation foundation lateral connection.The feature of this kind of roof ventilator is that rainproof effect is good.
But, existing roof ventilator all has following shortcoming, when roof ventilator is installed, the mounting base that roof must arrange level is placed fixing for roof ventilator, because this mounting base is not roof original structure, therefore need to install additional when roof ventilator is installed temporarily, add the user cost of roof ventilator, and increase the installation difficulty of roof ventilator, extend installation period.
Summary of the invention
For overcoming the deficiencies in the prior art and Problems existing, the utility model provides a kind of modular parlor top fan, and structure is simple, and versatility is high, can directly be installed on roof, shortens installation period, effectively reduces costs.
The utility model is achieved through the following technical solutions:
A kind of modular parlor top fan, comprise cylindrical shell, fan blade and driving mechanism, fan blade is driven by driving mechanism, and fan blade and driving mechanism are all positioned at cylindrical shell.The end face button of described cylindrical shell is provided with rainhat, and the border of rainhat is exhaust outlet, and the below of cylindrical shell is provided with pedestal, and the end face of pedestal engages with the sealing bottom surface of cylindrical shell, and the bottom surface of pedestal is plane of inclination.
The inclination of the bottom surface of described pedestal is 5 ° to 45 °.
The bottom surface of described cylindrical shell is provided with the first flange, and the end face of described pedestal is provided with the second flange, and the first flange and the second flange are bolted.
The first seal ring is provided with between described first flange and the second flange.
The bottom surface of described pedestal is provided with three-flange, and three-flange is connected and fixed by bolt and roof.
Described is provided with the second seal ring between three-flange and roof.
Described driving mechanism comprises motor and support, and support is fixed in cylindrical shell, and motor is fixed on support, and the output shaft of motor is connected with fan blade.
The top of described rainhat is provided with hanger.
The bottom surface of the pedestal that the utility model is arranged is plane of inclination, directly can be installed on the roof of inclination, thus avoid installing mounting base additional on roof temporarily, pedestal can arrange plurality of specifications, be applicable to the different roof of inclination to use, make the application of modular parlor top fan more extensive; The first seal ring arranged and the second seal ring effectively stop that rainwater infiltrates, and rainproof effect is better.
