The invention discloses a safety early warning device for sewer flow in the heavy rainfall weather. The safety early warning device for sewer flow in the heavy rainfall weather comprises a sensor waterproof fixing device and a flow speed pressure difference sensor assembly, wherein the sensor waterproof fixing device is horizontally arranged at the intersection of a horizontal water drain pipeline portion and a well lid lower vertical water drain pipeline portion and comprises a rectangular waterproof containing shell; sealing rings are arranged on round through holes in the front end of the waterproof containing shell; a waterproof shockproof layer is arranged on the inner wall; the waterproof containing shell is internally and sequentially provided with a first waterproof partition board, a second waterproof partition board and a third waterproof partition board in the length direction; the three partition boards divide the interior of the waterproof containing shell into four mutually waterproof cavities. A sensor is arranged in the waterproof containing shell, the waterproof performance is enhanced, water enters two of the cavities through the round holes after the device is used for a long time and will not affect the core component of the sensor, the waterproof performance of the sensor is enhanced, the service life is prolonged, and the maintenance cost is reduced.
