The invention discloses a shaft type pump device with an annular water inlet groove, and belongs to the technical field of hydraulic engineering. The shaft type pump device comprises a shaft, a pump section, a horn pipe, a water outlet pipe and a water inlet pipe, and is characterized in that a water distributing vessel is arranged and located above guide blades, the bottom of the inner wall of the water distributing vessel is flush with the bottom of the inner wall of the water inlet pipe, the top of the water distributing vessel is flush with the top of the inner wall of the water inlet pipe, the clear weight is equal to the diameter of the water inlet pipe, the water distributing vessel is directly connected with the water inlet pipe, and water flows into the water distributing vessel through the water inlet pipe and reaches an inlet of the horn pipe of the water pump through a water inlet groove. The pump device is suitable for various shaft type water inlet modes, the formation ofvortexes can be reduced to make the water flow more smoothly, the overall performance of the pump device is obviously improved, the energy is saved, and the consumption is reduced.
