Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

Referring to fig. 1, 3 and 4, the water pump with the leakage alarm function includes a water pump body 1, a main shaft 8 is installed in the water pump body 1, an impeller 6 is installed at one end of the main shaft 8, a transmission gear 10 is installed at the other end of the main shaft 8, a main shaft bearing 9 and a water seal assembly 7 are further installed on the main shaft 8, a water cavity 12 is arranged on the water pump body 1, the water cavity 12 is communicated with a water drainage hole 11, and the water drainage hole 11 is located in the water pump body 1 in the area between the main shaft bearing 9 and the water seal assembly 7.

The drain hole 11 is preferably a threaded hole. The water outlet 11 is communicated with an alarm device 5 through a connecting pipeline 3, the first end of the connecting pipeline 3 is connected with the water outlet 11, and the second end of the connecting pipeline 3 is connected with the alarm device 5.

As shown together with fig. 1 and 2, the alarm device 5 includes a mounting seat 52, a cup body 51 is mounted on the mounting seat 52, and the cup body 51 is preferably screwed with the mounting seat 52.

A liquid level sensor 54 is mounted on the cup body 51, and the liquid level sensor 54 extends into the cup body 51. The level sensor 54 is preferably located in the middle of the cup 51. The level sensor 54 is electrically connected to a controller (not shown) of the engine.

An overflow pipe 55 is arranged on the mounting seat 52, the overflow pipe 55 is communicated with the cup body 51, the overflow pipe 55 can extend into the cup body 52, and when the water collected in the cup body 51 reaches a certain amount, the water is discharged to the external environment through the overflow pipe 55.
