Embodiment 1

[0021] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a new type of marine axial flow fan of the present invention includes a casing 1, a motor 2, an impeller 3, a transmission group 4, a tire coupling 5, an explosion-proof ring 6, an inner interlayer cylinder 7, a water dividing plate 8, and a drain pipe 9. Partition plate 10 and protective net 11, motor 2 is installed in the inner sandwich tube 7, the motor 2 is connected with the impeller 3 through the tire coupling 5 and the transmission group 4, and the sea breeze in the cabin passes through the inner sandwich tube 7 to connect with the engine during operation. The gap of the casing 1 is discharged through the top of the casing 1 without passing through the motor 2. The water dividing plate 8 is installed on the partition 10 on the top of the inner interlayer cylinder 7. The rainwater passes through the water separating plate 8 and passes through the casing 1 on both sides, along the The drai...

Abstract

The invention relates to a novel axial flow fan for a ship, which comprises a housing, a motor, an impeller, a transmission group, a tire coupler, an anti-explosion ring, an inner interlayer cylinder, water distribution plates, drainage pipes, partition plates and a protecting net, wherein the motor is mounted in the inner interlayer cylinder, and connected with the impeller by the tire coupler and the transmission group; the water distribution plates are mounted on the partition plates at the top of the inner interlayer cylinder; and the anti-explosion ring is made of a brass plate. The axial flow fan is simple in structure, simple to operate, long in service life and high in safety performance, and the motor cannot be subject to corrosion of a sea breeze.

Description

technical field [0001] The invention relates to a ventilator, in particular to a novel marine axial flow fan. Background technique [0002] Traditional marine axial flow fans are usually installed in combination with hoods and transition ducts, so they take up a lot of space and are complicated to operate. When turning on and off the axial flow fans, it is necessary to open and close the watertight cover of the hood accordingly. [0003] When the traditional marine axial flow fan is working, the sea breeze inside the cabin will directly pass through the motor. Because the sea breeze is corrosive to a certain extent, it will corrode the power system of the fan, thus affecting the service life of the fan. Contents of the invention [0004] In order to solve the deficiencies in the prior art that there are many components in the axial flow fan system, the operation is complicated, the space occupied is large, and the axial flow fan is easily corroded by the sea breeze, the pr...
