Description

Technical Field

[0001] This utility model belongs to the field of motor rainproof technology, specifically relating to a novel rainproof device for flange-type motors. Background Technology

[0002] In many industrial sectors, such as mines, ports, and construction sites, electric motors are widely used to drive various mechanical equipment, such as cranes, conveyor belts, and excavators. These machines often operate in open-air environments; for example, the motors on port gantry cranes must withstand sun exposure, rain, and sea breezes. Without rain protection, the electrical components inside the motor are easily affected by moisture, leading to short circuits and equipment failure. Rainwater entering the motor can degrade the insulation of the windings, shortening the motor's lifespan. Rain protection devices effectively prevent rainwater, dew, and other liquids from entering the motor, ensuring its normal operation even in harsh outdoor weather conditions.

[0003] Therefore, this invention proposes a novel rainproof device for flange-type motors, which provides rain and water protection for the anchoring motors of automated rail gantry cranes, preventing the motors from being corroded by rainwater.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] See attached document Figure 1-8 A novel rainproof device for flange-type motors includes:

[0032] The base plate 1 includes a first plate and a second plate; the first plate is vertically arranged, and a fixing lug is inclinedly arranged on each side of its bottom to fix it to the flange; an arc-shaped notch is opened between the two fixing lugs; the second plate is horizontally arranged above the motor and the gearbox.

[0033] Junction box protective cover 2 is inverted L-shaped, with baffles at both the front and rear ends; the top plate of junction box protective cover 2 is fixed above the second plate, and the side plates are located on the sides of the motor and gearbox.

[0034] The cooling fan guard 3 has its top plate fixed above the junction box protective cover 2 and its side plates located on both sides of the motor tail.

[0035] In this embodiment, the top of the second plate has two fixing holes one and two fixing holes two; the top plate of the junction box protective cover 2 is locked to the fixing hole one by bolt one; the top plate of the cooling fan guard frame 3 is locked to the fixing hole two by bolt two; bolt two passes through the top plate of the cooling fan guard frame 3, the top plate of the junction box protective cover 2 and the second plate.

[0036] During actual installation, firstly, based on the overall shape of the anchor motor and the fixing method of the motor flange, a 2mm stainless steel plate is installed on the motor and gearbox to form the mounting base plate 1 through cutting and sheet metal work. Then, according to the orientation of the motor junction box, the junction box protective cover 2 is installed on the first plate of the base plate 1 using 6mm semi-circular head bolts. Finally, to prevent water from entering the cooling fan at the rear of the motor due to rain, a U-shaped bent plate slightly larger than the overall size of the motor is used as the cooling fan guard frame 3, and is installed upside down on the motor junction box protective cover 2 using 6mm bolts.
