[0002] At present, there are a large number of traditional structural motors. Motors are resource-based products with heavy material consumption, high energy consumption and high pollution. With the development of material industry standardization in recent years, heavy material consumption can be recycled sustainably, and key technologies such as motor redesign, remanufacturing and re-resource utilization can fundamentally solve the above-mentioned resource and environmental shortcomings and energy-saving ecological environment.

[0003] When the motor is working, the presence of the stator assembly will generate a lot of heat. As the heat increases, the temperature inside the motor cavity rises, and the water vapor inside the motor condenses to produce water droplets. As the condensed water accumulates, the motor will short circuit or voltage failure. Therefore, there is an urgent need for a drainage structure that can be applied to traditional motors without drainage function to solve the problem of condensed water accumulation.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a condensate discharge end cover suitable for remanufacturing motors, comprising an end cover 1 suitable for vertically installing the tail end of the motor, the inner center of the end cover 1 is an axial hole 2, the edge is provided with a connection hole 3 for connecting with the motor housing, the inner bottom surface of the end cover 1 is provided with a water collecting tank 4, and the inner side of the end cover 1 is provided with a reinforcing rib. To improve the structural strength of the end cover 1, a water hole is provided at the bottom of the reinforcing rib so that the condensate can flow into the water collecting tank 4, and a drainage mechanism 5 is provided in the water collecting tank 4, and the drainage mechanism 5 is cylindrical and installed vertically;

[0018] The drainage mechanism 5 includes a main body 51 and a mounting frame 57. The mounting frame 57 is fixed to the bottom of the main body 51 by screws. The mounting frame 57 is cross-shaped and does not hinder the outflow of condensed water. The inside of the main body 51 is a drainage hole 52. The drainage hole 52 is a conical hole that is small at the top and large at the bottom. A central axis 54 is arranged on the mounting frame 57. A blocking block 53 is slidably mounted on the central axis 54. The blocking block 53 is a cone that is small at the top and large at the bottom and is located in the drainage hole 52. A spring 55 is mounted on the central axis 54. The spring 55 provides an upward elastic force for the blocking block 53. A cushion block 56 is arranged on the central axis 54. The cushion block 56 is located at the bottom of the spring 55. The cushion block 56 is a self-locking nut. The central axis 54 is provided with a self-locking thread. The compression amount of the spring 55 can be adjusted by the cushion block 56, thereby adjusting the critical pressure required for the drainage mechanism 5 to be turned on.

[0019] When in use: Under normal conditions, the block 53 is blocked in the drain hole 52 like a plug under the action of elastic force, isolating the internal and external spaces of the motor. When the motor is started, the air inside the motor is stirred after the rotor rotates, and the air pressure is greater than that outside. When the internal and external pressure difference of the block 53 is greater than the elastic force of the spring 55, the block 53 moves downward and disengages from the drain hole 52, so that the condensed water in the sump 4 can be discharged through the drain hole 52. After the motor stops working, the block 53 is blocked in the drain hole 52 again, isolating the internal and external spaces of the motor. In addition, when the condensed water in the sump 4 accumulates to a certain amount, even if the motor is not started, the dead weight of the condensed water is greater than the elastic force of the spring 55, and the block 53 will also move downward and disengage from the drain hole 52, so that the condensed water in the sump 4 can be discharged through the drain hole 52.

[0020] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
