Embodiment 1

[0047] A water retaining ring, comprising a support part 4 and a water retaining part 5 connected to the support part 4, the support part 4 is sleeved on the end cover 1, the number of the water retaining parts 5 is two and the two water retaining parts The longitudinal section of 5 forms a V-shaped structure, the support portion 4 is distributed along the axial direction of the motor shaft 7 and the two support portions are connected by a connection portion 8, the support portion 4 is arranged on the side of the connection portion 8 close to the motor shaft 7, and the connection portion 8 and the longitudinal section of the water retaining part 5 form a Y-shaped structure. The water retaining ring provided by the present invention has simple structure, low cost, self-contained drainage channel, reliable waterproof effect, and the waterproof grade can be raised to IPX6.

Embodiment 2

[0049] A motor includes the water retaining ring described in the embodiment. The water retaining ring, the waterproof cover 2 and the end cover 1 together form a semi-open waterproof structure. When water is strongly sprayed on the waterproof cover 2, the waterproof cover 2 will be deformed, and the water will spread into the waterproof cover 2 along the first boss 9, and the outer water retaining part 51 can block most of the water by using its slope. This part of the water will flow out from top to bottom; the other part of the water may overflow the highest part of the outer water retaining part 51, and flow along the inner side of the outer water retaining part 51 to the inner receiving chamber 3, and the inner water retaining part 52 can prevent it from going up Continuing to spread, the water can be discharged from the water retaining ring through the inner water retaining part 52 and the drainage holes 6 on the two support parts 4 .

Abstract

The invention provides a water-retaining ring and a motor with the water-retaining ring, and relates to the technical field of the motor. The technical problem that the vertically installed motor in the prior art is single in waterproof structure. The device comprises a water-retaining ring body, the water-retaining ring body is sleeved on a motor end cover, a part extending into the water-retaining ring body and protruding from a top surface of the end cover is existent on the water-retaining ring; a drainage channel is arranged on the water-retaining ring body, the water flowing into the water-retaining ring body can flow to the outside of the water-retaining ring body through the drainage channel. The water-retaining ring provided by the invention is used for realizing the waterproof ofthe vertically installed motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a water retaining ring and a motor with the water retaining ring. Background technique [0002] The existing vertically upwardly installed motor requires the waterproof level to be raised from IPX4 to IPX6. IPX4 requires that water splashed in all directions of the shell has no harmful effects, and IPX6 requires strong water sprayed in all directions of the shell without harmful effects. [0003] Such as figure 1 As shown, this waterproof structure with a waterproof cover on the shaft covers the open end cover, which can meet the IPX4 waterproof requirements. However, when the water pressure increases to meet the requirements of IPX5 and IPX6, the waterproof cover is deformed, and the boss of the end cover cannot prevent water from spreading into the motor. [0004] Such as figure 2 As shown, this waterproof structure with an oil seal added between the open end cover and the m...
