Description
Technical Field
The utility model relates to a centrifugal roof fire control smoke exhaust fan of full aluminium system belongs to fan technical field.
Background
At present, centrifugal roof fan is widely used in the ventilation of workshop factory building, warehouse, hotel, high-rise building and other places, but it is usually installed in the open air environment, it is more serious to be corroded by bad weather such as stormy wind and rainstorm, and need maintain and repair after the motor is used for a long time, in order to reach the purpose of protection motor, the motor outside all fixedly installed has the hood, need to demolish the hood earlier when maintaining and repairing the motor, wait to maintain and repair and install the hood after good, and the volume and the weight of hood all great dismouting consume time power, it is very inconvenient.
Disclosure of Invention
The utility model aims to solve the technical problem that a centrifugal roof fire control smoke exhaust fan of full aluminium system is provided, makes things convenient for the maintenance and the maintenance of inside motor, can solve the not enough of prior art.
The technical scheme of the utility model is that: the utility model provides a centrifugal roof fire control smoke exhaust fan of full aluminium system, includes the support, through the motor of support mounting on the support, installs the impeller in the motor shaft, installs the hood on the support, forms the air-out passageway between hood and the support, the hood is the upper and lower extreme all open barrel, the detachable cap is installed to hood upper end opening part, the cap can be sealed hood upper end opening, and support, hood and cap are aluminium alloy system material. The internal motor can be maintained and repaired by disassembling and assembling the cap, and the support, the hood and the cap made of aluminum alloy have higher strength, lighter weight, excellent corrosion resistance, convenience in installation and better service life.
Further, the cap cover and the blast cap are fastened and fixed through a plurality of buckles. The cap is buckled at the opening at the upper end of the hood and then fastened and fixed through the lock catch, so that the cap is convenient to be fixedly arranged on the hood.
And a fence or a separation net is arranged between the blast cap and the support. The fence or the separation net can prevent mice, birds and the like from entering and damaging the motor, the impeller and the like without affecting the exhaust air discharged through the air outlet channel.
Further a sealing ring is arranged at the joint of the cap and the blast cap. Increase the cap and be connected the back leakproofness with the hood, prevent that rainwater infiltration from causing the harm to the motor.
To sum up, the utility model provides a make things convenient for centrifugal roof fire control smoke exhaust fan of full aluminium system of maintenance and maintenance of inside motor.

Shown in the figure: a support 1; a motor 2; an impeller 3; a hood 4; an air outlet channel 5; a cap 6; a lock catch 7; a fence 8; a fixed portion 9; a movable portion 10; a seal ring 11; a support post 12.
Detailed Description
The embodiment of the utility model provides a: as shown in fig. 1 to 3, a centrifugal roof fire control smoke exhaust fan of full aluminium system, including support 1, motor 2 through the support mounting on the support, install impeller 3 in the motor shaft, install hood 4 on the support, form air-out passageway 5 between hood 4 and the support 1, hood 4 is the barrel that upper and lower extreme all opened, detachable cap 6 is installed to 4 upper end openings of hood, cap 6 fits and fixes with hood 4 after 4 upper end openings of hood and seal, support 1, hood 4 and cap 6 are aluminium alloy system material. Support 1 installs on the roof, and motor 2 drive impeller 3 rotates, and indoor air passes through support 1 inside again through air-out channel 5 discharge outdoor, can maintain and maintain inside motor 2 through dismouting cap 6, and support 1, hood 4 and cap 6 that the aluminum alloy made have higher intensity and lighter quality and have good corrosion resistance, have made things convenient for the installation also to have better life.
The cap 6 and the hood 4 of the preferred embodiment are fastened and fixed by a plurality of latches 7. The lock catch 7 is composed of a movable part 10 which is connected to the outer wall of the cap 6 in a switching mode and a fixed part 9 which is fixed to the outer wall of the hood 4, the six lock catches 7 are evenly distributed along the circumferences of the cap 6 and the hood 4, the cap 6 is closed and opened to the hood 4 through combination and separation of the movable part 10 and the corresponding fixed part 9, and operation is convenient.
Between the hood 4 and the support 1, a fence 8 is preferably arranged in the present embodiment. The hood 4 is installed on the support 1 through the struts 12 which are distributed circumferentially, and the fence 8 is arranged on the struts 12 in an enclosing mode and can prevent mice, birds and the like from entering the fan to damage the motor 2, the impeller 3 and the like without affecting the exhaust of the exhaust air through the air outlet channel 5.
The preferred cap 6 of the present embodiment is provided with a sealing ring 11 at the junction with the hood 4. The cap 6 is a conical shape and is beneficial to rainwater sliding, the sealing ring 11 is arranged at the joint of the cap 6 and the blast cap 4 to enhance the sealing performance, and the motor 2 is prevented from being damaged by rainwater infiltration.
