Water taking pump protection device for centrifugal pump and siphon barrel

The invention relates to the technical field of centrifugal pumps and siphon barrels, and discloses a water taking pump protection device for a centrifugal pump and a siphon barrel, which comprises a siphon barrel, the upper surface of the siphon barrel is communicated with a water inlet pipe, the lower surface of the siphon barrel is communicated with a water outlet frame, and one end, far away from the siphon barrel, of the water outlet frame is communicated with a centrifugal pump; a measuring part is arranged in the siphon barrel, and a protection part is arranged on the surface of the siphon barrel. When the floating plate moves upwards, the bent rod is pushed to move upwards through the sliding rod, and the measuring rod is pushed to move, so that the water level in the siphon barrel is observed through the measuring rod, and the situation that due to the fact that the water level in the siphon barrel is lowered, air enters the centrifugal pump, and the centrifugal pump is damaged is avoided; when the f
