[0047] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the solution provided by the embodiments of the present invention will be described in detail with reference to specific embodiments below.

[0048] Example 1

[0049] like Figure 1 As shown, an embodiment of the present invention provides an axial-flow water pump capable of achieving bidirectional water flow, comprising a pump body 1, an impeller 2, guide vanes 3, and a motor 4. The pump body 1 is provided with a water inlet 5 and a water outlet 6. The impeller 2 is mounted on the central axis of the pump body 1 and connected to the motor 4. The guide vanes 3 are provided on both sides of the impeller 2 to guide the direction of water flow. The motor 4 drives the impeller 2 to rotate, thereby generating water flow.

[0050] See also Figure 3 Since the impeller 2 adopts a design of multiple straight blades, this design of the impeller 2 enables effective water flow to be generated during both forward and reverse rotation, and cooperates with the guide blades 3 provided on the lower side to achieve a true two-way flow function. The number of straight blades of the impeller 2 is no less than 13, and the straight blades are in the shape of a trapezoidal structure. Since the number and shape of the blades are optimized, the efficiency and performance of the water pump can be improved. The guide blades 3 can play a role in guiding flow. The first valve mechanism 7 and the second valve mechanism 15 are respectively provided in the two-way flow channel structure serving as a two-way water inlet channel, which can effectively reduce the turbulence caused by the vortex generated near the rear wall. The first valve mechanism 7 and the second valve mechanism 15 are electric valves or pneumatic valves, which can be remotely controlled.

[0051] Motor 4 is a high-efficiency, energy-saving motor that reduces energy consumption and improves the overall performance of the pump. Motor 4 is connected to impeller 2 via a direct-coupling shaft 8. A mounting bracket 9 is located at the bottom of pump body 1, facilitating securement of the pump in various operating environments. A protective cover 10 is located on the outside of pump body 1 to protect it from the external environment.

[0052] In summary, the axial-flow water pump of the present invention has a simple structure and is easy to manufacture and maintain. It enables bidirectional flow, increasing the pump's flexibility and application range. By changing the impeller's rotational direction, the direction of water flow can be easily changed. The provision of two valve mechanisms enables more precise and reliable control of water flow direction. The use of corrosion-resistant materials in the pump body enhances its durability and reliability. The optimized impeller design improves the pump's efficiency and performance. The use of a high-efficiency, energy-saving motor reduces energy consumption and improves the pump's overall performance. The provision of a protective cover and mounting bracket makes the pump more adaptable to diverse operating environments. This axial-flow water pump significantly expands its application scenarios, playing a particularly important role in water conservancy projects, agricultural irrigation, urban flood control, and other fields. This design not only improves the pump's efficiency and reliability, but also significantly reduces energy consumption, potentially bringing significant economic benefits. The bidirectional flow channel structure is expected to reduce energy consumption by at least 15%, making it particularly suitable for large-scale applications such as agricultural irrigation and urban water supply systems. The optimized flow channel design and self-cleaning function reduce the number of daily maintenance times, and are expected to save more than 5% of maintenance costs each year. In the long run, the economic benefits are very obvious.
