Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a bottom-suction water pump structure. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base solutions, emulsions, suspension emulsions, and liquid metals, etc. It can also transport liquid-gas mixtures and liquids containing suspended solids. The technical parameters of the water pump performance include flow rate, suction lift, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into types such as positive-displacement water pumps and vane pumps. A positive-displacement pump uses the change in the volume of its working chamber to transfer energy; a vane pump uses the interaction between the rotating vane and water to transfer energy, and there are types such as centrifugal pumps, axial-flow pumps, and mixed-flow pumps.

[0003] Existing water pumps are prone to blockage at the water suction port when dealing with water sources containing solid particles or having a high turbidity, resulting in the water pump being unable to work, and even possibly causing the water pump to burn out. For this reason, we propose a bottom-suction water pump structure. Content of the Utility Model

[0004] In view of the above problems, the utility model provides a bottom-suction water pump structure, which has high operation stability, low maintenance cost, and can adapt to various environments.

[0005] The technical solution of the utility model is as follows:

[0006] A bottom-suction water pump structure includes a water pump top cover. A control box top cover is installed at the bottom end of the water pump top cover. A control box is installed at the bottom end of the control box top cover. A water pump barrel body is installed at the bottom end of the control box. A water pump volute is installed at the bottom end of the water pump barrel body. A water pump mesh cover is installed at the bottom end of the water pump volute. A water pump base is installed at the bottom end of the water pump mesh cover. A stator protection tube is installed in the middle part of the water pump barrel body. A low-voltage stator coil is installed inside the stator protection tube. A motor inner tank is installed inside the low-voltage stator coil. A low-voltage rotor is installed inside the motor inner tank. An inner tank cover is installed at the bottom end of the motor inner tank. A water pump impeller is installed on the output shaft of the low-voltage rotor.

[0007] In a further technical solution, the outer shape of the water pump mesh cover is cylindrical, and the outer wall of the water pump mesh cover adopts a mesh structure.

[0008] In a further technical solution, six support angles are provided at the bottom end of the water pump base.

[0009] In a further technical solution, two handles are provided on the water pump top cover.

[0010] In a further technical solution, both the water pump barrel body and the stator protection tube adopt a cylindrical structure.

[0011] The beneficial effects of the present utility model are as follows:

[0012] This device adopts a bottom-suction water intake method, which can effectively improve the water intake efficiency. At the same time, when dealing with water sources containing solid particles or having a high turbidity, by sucking water from the bottom, the water pump can effectively avoid sucking in impurities floating on the water surface, ensuring that the extracted water quality is purer. Moreover, it can adapt to some special environments, such as deep wells, the bottom of ponds or low-lying areas, where traditional water pumps may be difficult to work effectively. The bottom-suction water pump can well adapt to these environments and give full play to its water intake advantages. Description of the Drawings
