This problem of poor hydrodynamic performance is a core technical challenge that urgently needs to be solved in current blade fork design. It directly affects the operating efficiency and energy utilization efficiency of the equipment, limiting the performance improvement of mechanical equipment in terms of efficient fluid power conversion or guidance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-4 As shown, this utility model is a hub-type blade fork, including...

[0027] The fork body is composed of multiple fork units connected end to end in sequence.

[0028] The fork unit includes a central connecting part 1 and at least one fork arm 2 extending from the outside of the central connecting part 1, and the fork arm 2 is provided with a transition connector 3.

[0029] As can be seen from the above, the blade fork body is formed by assembling at least two blade fork units. The streamlined fork arm 2 design and the smooth transition connector 3 structure can significantly reduce the resistance and turbulence of fluid flow, improve the energy conversion efficiency of the equipment, and the stress dispersion effect of the transition connector 3 structure gives the blade fork high strength and fatigue resistance, enabling it to withstand large loads and high-speed operation, and extend the service life of the equipment.

[0030] Depend on Figures 3-4 It can be seen that the blade fork body is hub-shaped.

[0031] As can be seen from the above, the hub-type structural design is based on the principles of fluid mechanics. Its streamlined shape can effectively reduce the resistance and turbulence of the fluid around the blade fork, thereby improving the fluid dynamics performance and enhancing the overall efficiency of the equipment.

[0032] Depend on Figures 1-2 It is known that the two ends of the transition connector 3 are respectively provided with a fastening block 4 and a fastening groove 5, and the fastening block 4 and the fastening groove 5 can be fastened together; the fastening block 4 is provided with a first connecting hole 6, and the fastening groove 5 is provided with a second connecting hole 7.

[0033] As can be seen from the above, specifically, the first connecting hole 6 is a through hole design, and the second connecting hole 7 is a screw hole design. In the specific assembly process, the workers connect several blade fork units end to end, that is, fasten the fastening block 4 and the fastening groove 5, so that the first connecting hole 6 and the second connecting hole 7 are located on the same central axis. After that, the workers install screws in the first connecting hole 6 and the second connecting hole 7 to assemble and connect the blade fork body.

[0034] This connection method not only ensures a secure connection between the blade fork units, but also facilitates quick assembly and disassembly, further improving the installation and maintenance efficiency of the blade forks.

[0035] Depend on Figure 1 and Figure 3 It can be seen that the central connecting part 1 is provided with a through mounting hole 8.

[0036] As can be seen from the above, the mounting hole 8 is designed for connection with the rotating shaft of the drive component. The drive components under the prior art include mechanical equipment that requires efficient fluid power conversion or guidance, such as fans, pumps, turbines, etc. The inner surface of the mounting hole 8 is provided with a keyway or thread. Through the keyway or thread engagement, a firm connection between the blade fork and the rotating shaft can be ensured, thereby ensuring the stability and reliability of the blade fork during operation.

[0037] The thickness of the central connection 1 can be designed according to the load borne by the blade fork to ensure sufficient strength.

[0038] Depend on Figures 1-4 It can be seen that some of the fork arms 2 are arc-shaped and their cross-sectional shape is streamlined.

[0039] Several of the fork arms 2 are equally spaced and arranged in a circular array on the outer wall of the central connecting part 1.

[0040] As can be seen from the above, the arc-shaped and streamlined design of the fork arm 2 can further optimize the fluid flow path and reduce resistance. At the same time, the equally spaced circumferential array layout can ensure the power transmission efficiency of the blades and improve the overall performance of the equipment.

[0041] The cross-sectional shape of the fork arm 2 is streamlined, similar to the cross-section of a wheel hub, with a blunt front end and a pointed rear end. This design can effectively reduce resistance and turbulence during fluid flow. The length and curvature of the fork arm 2 are optimized according to the size of the blade and the installation angle to ensure that the blade can obtain the best power transmission.

[0042] Depend on Figure 1 , Figure 3 and Figure 4 It can be seen that the transition connector 3 is a smooth arc-shaped transition structure.

[0043] As can be seen from the above, the smooth arc transition structure can effectively disperse stress and avoid stress concentration, thereby improving the overall strength and fatigue resistance of the blade fork and extending its service life. At the same time, the transition connection structure also helps to improve the flow state of the fluid around the blade fork.

[0044] Depend on Figures 1-2 It is known that the blade fork unit is made of high-strength lightweight alloy material.

[0045] As can be seen from the above, the selection of high-strength lightweight alloy materials, such as aluminum alloys or titanium alloys, can not only ensure the strength and stability of the blade fork when subjected to large loads, but also reduce the weight of the blade fork, reduce the moment of inertia, and improve the response speed and operating efficiency of the equipment.

[0046] Depend on Figure 2 and Figure 4It can be seen that a number of reinforcing plates 9 are fixedly connected between the central connecting part 1 and the fork arm 2.

[0047] As can be seen from the above, the setting of the reinforcing plate 9 further enhances the overall structural strength of the blade fork, especially when subjected to large loads or high-speed operation, it can effectively prevent deformation and ensure the long-term stable operation of the blade fork.
