Description

Technical Field

[0001] The utility model relates to a floating ship type axial flow pump station, belonging to the technical field of floating pump stations. Background Art

[0002] A floating pump station is a special type of pump station that uses the maneuverability and practicality of floating boats to take in or drain water from rivers, lakes or reservoirs. The floating boat can be moved to different waters to take in or drain water as needed, and has strong adaptability. Compared with traditional pump stations that require complex projects such as cofferdam construction and pump house construction, the construction period of a floating pump station is greatly shortened.

[0003] Generally speaking, floating pump stations use submersible pumps as core equipment. Submersible pumps use water cooling to ensure the normal operation of the motor. During the operation of the submersible pump, water not only serves as the medium to be transported, but also plays a role in cooling the motor. When the motor is running underwater, the surrounding water can fully cover the motor part and take away the heat generated by the motor through heat exchange, thereby ensuring the normal operation of the motor and preventing the motor from overheating.

[0004] Submersible pumps are installed on floating boats. If the motor floats to the surface, the water will not be able to fully cover the motor part, resulting in insufficient cooling of the motor. In this case, the heat generated by the motor cannot be dissipated in time, and will accumulate inside the motor and cause the motor temperature to rise. If the motor runs at high temperature for a long time, it will not only affect its working efficiency and life, but may also cause serious consequences such as motor burnout. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a floating axial flow pump station which can ensure the heat dissipation effect and prevent the pump from burning, so as to solve the above problems.

[0006] The floating ship type axial flow pump station described in the utility model has a hull including a buoy, a vertical pump barrel is arranged on the hull, an axial flow pump is installed at the lower end of the pump barrel, a drainage port is arranged at the upper end of the pump barrel, and the height of the drainage port is higher than the motor used to drive the axial flow pump.

[0007] The structure of the axial flow pump is easy to install in a vertical pump barrel. Since the discharge port is set at the upper end of the pump barrel, when working, the axial flow pump allows water to move along the axial direction, which can fill the pump barrel and immerse the motor driving the axial flow pump in water. Regardless of the depth of the water level and the draft of the hull, the motor can be immersed in the flowing water during operation, taking away the heat generated by the motor and allowing the motor to be fully cooled.

[0008] Wherein, a steel frame is arranged on the buoy to enhance the structural strength of the hull.

[0009] Preferably, a guardrail is installed at the edge of the steel frame to prevent people from falling into the water.

[0010] Preferably, a stepped necking is provided at the lower end of the pump barrel to facilitate the installation of the axial flow pump.

[0011] Preferably, the floating barrel is in a square shape with a hole in the middle, and the pump barrel is arranged at the center of the floating barrel.

[0012] As needed, multiple groups of the floating barrels can be arranged side by side.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] In the floating ship type axial flow pump station of the present utility model, by designing the pump barrel, the pump barrel can be automatically filled with water when the axial flow pump is working, so as to ensure that the motor driving the axial flow pump is always immersed in the flowing water body. This method effectively ensures the sufficient cooling of the motor during operation, avoiding serious consequences such as efficiency reduction, shortened lifespan, or even burnout caused by overheating of the motor. Regardless of the changes in water level depth or the draft of the hull, the effective heat dissipation of the motor can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

A stepped necking 8 is provided at the lower end of the pump barrel 2 to facilitate the installation of the axial flow pump.
