This utility model provides a deep well pump with rapid water intake, belonging to the field of deep well pumps. It solves the problem that traditional deep well pumps extract liquid by rotating an impeller, whose water intake efficiency relies entirely on the impeller's rotation speed, lacking independent water intake mechanisms and structures. Slow water intake efficiency leads to slow overall water delivery and discharge. This utility model includes a deep well pump body, an impeller chamber, a water outlet pipe located above the deep well pump body, and a water inlet pipe located below the deep well pump body. The key feature is that the water inlet pipe has an inlet port perpendicular to it. The inner wall of the inlet port has several annularly arranged blocking parts, with an inlet groove between every two adjacent blocking parts. Each blocking part has several stepped water-blocking parts, and a guiding water part is located below each blocking part, with guide grooves formed between the guiding water parts.

This utility model relates to the field of water conservancy facilities, specifically disclosing a vortex-breaking device for the inlet of a hydropower station unit. The device includes a central pipe, an outer baffle located outside the central pipe, an inner baffle located inside the central pipe, and several auxiliary inlets on the side of the central pipe. A floating unit is located on the upper side of the central pipe. When in use, this device needs to be placed in an area prone to vortex formation. The device obtains its main buoyancy through the floating unit and only requires simple rope fixation to prevent it from drifting with the water flow. When water flows towards the turbine, the outer baffle effectively blocks the water flow rotation, suppressing vortex formation at the source. To improve water intake efficiency, several auxiliary inlets are added to the central pipe. Simultaneously, to prevent water flow rotation inside the central pipe, an inner baffle is installed on the inner side of the central pipe, referencing the vortex-breaking principle of the outer baffle.
