[0014] Example: Please refer to Figure 1-2 , a valve well drainage device includes a pump body 1 and a motor 2. An impeller assembly 3 is provided in the pump body 1. The output shaft of the motor 2 extends to the interior of the pump body 1 and is connected to the impeller assembly 3. The pump body 1 is connected with an inlet pipe 4 and a water outlet pipe 5. The inlet pipe 4 is connected to the bottom of the valve well through the drainage pipe, and the impeller assembly 3 is driven by the motor 2 to rotate, so that the sewage is discharged from the valve well to the outside; a filter assembly 6 is provided at the inlet end of the water inlet pipe 4, and the filter assembly 6 includes a V-shaped pipe 61 and a filter screen 62. The V-shaped pipe 61 is connected to the water inlet pipe 4, and the filter screen 62 is arranged in the V-shaped pipe 61. The bottom of the V-shaped pipe 61 is connected with a discharge pipe 63. When sewage enters the V-shaped pipe 61, the filter screen 62 filters out large particles of impurities, preventing large particles of impurities from entering the pump body 1, thereby preventing large particles of impurities from damaging the pump body 1 and the impeller assembly 3, and also preventing large particles of impurities from clogging the pump body 1; the discharge pipe 63 can easily clean up the impurities in the V-shaped pipe 61.

[0015] The filter screen 62 extends from the top of the V-shaped tube 61 to the bottom of the discharge tube 63, and the filter screen 62 is set at an angle, which can increase the filtering area of ​​the filter screen 62. At the same time, impurities will fall into the discharge tube 63 along the filter screen 62 to avoid clogging of the filter screen 62; the filter screen 62 is stuck in the V-shaped tube 61 and can be pulled out of the V-shaped tube 61, thereby facilitating quick replacement of the filter screen 62.
