Abstract
A flexible coupling wagon roof fan comprises a fan housing, a motor air inlet, a motor housing, a muffling heat-insulation layer, a perforated grill, a guide vane, a motor and an impeller, etc., which is characterized in that: a circular channel is formed between the motor and the perforated grill, the lower end of the motor housing is fixedly connected with a ventilation ring, the lower end of the fan housing is provided with a drain hole and connected with a rain cover, the rain cover arranged inside the fan housing is assembled with a flashing board, and the upper end of the fan housing connects with a protective screening. The utility model has the advantages of increasing the ventilation quantity of the motor temperature reduction; besides, the utility model establishes a low-temperature air-flow layer between the motor and the impeller, which solves the problems of the common motor, such as dust-proof, damp-proof and temperature reduction, with good use effect, thereby prolonging the life span of the motor.
Description
The utility model belongs to a kind of centrifugal blower, particularly a kind of resilient connection tubular roof ventilator.
Be installed in the centrifugal blower on roof at present, its motor adopts common electric machine more, and motor is exposed in the Environmental Conditions, lowers the temperature by natural heat dissipation, subjects to humidity, dust infringement, influences its working life.
The purpose of this utility model provides a kind of resilient connection tubular roof ventilator, motor dust and moisture, good cooling effect, and blower fan cancellation rainhat is more suitable for the high-altitude and uses.
The purpose of this utility model is achieved by the following technical solution: it comprises Fan casing, motor intake grill, motor casing, noise elimination thermal-protective coating, perforated plate, stator, motor, impeller etc., it is characterized in that: between motor and perforated plate, constitute annular channel, the affixed venting ring in the lower end of motor casing, in the lower end of Fan casing the weep hole parallel connection is set and takes over control canopy, on the rain cover of Fan casing inboard, assemble flashing board, connect protective net in the upper end of Fan casing.Working principle: by motor intake grill inspiration natural wind, and through annular channel and venting ring between motor and the perforated plate, discharge from ventilated port vertically, effectively accelerate the discharge of motor heat, simultaneously because axial ventilation makes common electric machine reach the effect of dust and moisture.Flashing board has solved in rainwater goes into, and protective net can prevent that foreign matter from entering in the blower fan,
The utility model is compared with prior art has following advantage: owing to adopt motor shaft to strengthen the motor ventilation amount to aeration structure, and between motor and impeller, set up a low-temperature airflow layer, efficiently solve the dust and moisture and the cooling of common electric machine, using effect is good.Prolong the working life of motor, can utilize rainwater to clean the interior dust of Fan casing simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment: see Fig. 1-3, motor casing 8 is fixed in the Fan casing 3 by stator 7, elastic insert 6 and link, motor casing 8 is provided with motor intake grill 11, and the entrance point of motor intake grill 11 is positioned on the Fan casing, motor casing 8 inboard assembling noise elimination thermal-protective material 9 and perforated plates 10.Supporting plate 16, coupling block 5 and the affixed motor 13 of connecting bolt are passed through in lower end at motor casing 8, constitute annular channel between perforated plate 10 and motor 13, the inboard affixed venting ring 15 of supporting plate 16 is a ventilated port 17 in the middle of the venting ring 15, motor shaft passes venting ring 15, the affixed impeller 4 of its front end.In the lower end of Fan casing 3 weep hole 14 is set, and connects rain cover 1 by coupling, the annular flashing board 2 of the certain slope that on the rain cover 1 of Fan casing 3 inboards, is fixedly connected, the upper end of Fan casing 3 connects protective net 12.
