Preferably, two liquid discharge ports are symmetrically arranged on the side surface of the shell, a blocking piece is arranged on the outer wall of the shell at the liquid discharge port, the side surface of the blocking piece is communicated with the shell through the liquid discharge port, an opening is formed in the bottom surface of the blocking piece, and one surface of the blocking piece, which is far away from the liquid discharge port, is obliquely arranged.

Preferably, the diameter of the blocking wheel is larger than that of the fixed wheel, and the setting height of the blocking wheel is not lower than the lower end of the liquid discharge port and not higher than the upper end of the liquid discharge port.

Preferably, the groove is provided with a clamping piece.

Preferably, the fixed pulley is made of fluororubber, and the rotating shaft is in interference connection with the fixed pulley.

Preferably, the lower part of the stopper is provided with a thread.

The beneficial effects of the utility model reside in that:

1. the utility model discloses an in the installation of keeping off the wheel, effectively played and blockked that liquid gets into the motor, keep off the wheel simultaneously and still can throw away liquid from the shell, the rethread keeps off the piece outflow, further reduction the risk that liquid got into the motor.

2. The utility model discloses a drainage device can be in pump body end, the mechanical seal of motor end lose behind the sealing under the long-term operation condition, play sealed effect, can prevent that liquid from getting into motor bearing chamber along the axle and inside the motor, prevent that the motor shaft from bearing the corruption of liquid, prevent that the motor from advancing liquid back insulation and reducing, prevent that the motor from burning out, can also provide the visual judgement reference of mechanical seal wearing and tearing, damage, reduce the emergence of equipment accident, and practice thrift economic expenditure.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

Example 1:

as shown in fig. 1 to 4, a drainage device for an electric motor comprises a housing 1, a catch wheel 2, a fixed wheel 3 and a rotating shaft 4, wherein the rotating shaft 4 penetrates through the housing 1, the rotating shaft 4 sequentially penetrates through the catch wheel 2 to be connected with the fixed wheel 3, one side of the fixed wheel 3 is connected with the catch wheel 2, the other side of the fixed wheel 3 is provided with a protruding part 31, a groove 32 is formed in the protruding part 31, and a drainage port 11 is formed in the side surface of the housing 1. The pivot 4 is the axle of the pump body 8, the utility model discloses a motor water retaining device installs between motor 7 seals and the pump body 8 seals.

Two liquid discharge ports 11 are symmetrically arranged on the side face of the shell 1, a blocking piece 5 is arranged on the outer wall of the shell 1 and located at the position of the liquid discharge port 11, the side face of the blocking piece 5 is communicated with the shell 1 through the liquid discharge port 11, so that liquid in the shell 1 is thrown into the blocking piece 5 by the blocking wheel 2, an opening is formed in the bottom face of the blocking piece 5, one face, far away from the liquid discharge port 11, of the blocking piece 5 is obliquely arranged, and the oblique arrangement is favorable for draining the liquid to flow out of the opening in the bottom face of the blocking piece 5.
