Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment: A composite high-efficiency water turbine, such as Figure 1-Figure 4 As shown, the chassis 1 and the top plate 2 are rotatably connected to the center of the chassis 1 and the top plate 2 with a wheel shaft 3, circular grooves 101 are provided on the opposite walls of the chassis 1 and the top plate 2, a plurality of detachable blades 4 are movably provided on the wheel shaft 3, the top plate 2 and the chassis 1 are detachably connected to the wheel shaft 3, a plurality of plug-in blocks 5 are distributed circumferentially on the side wall of the wheel shaft 3, the plug-in block 5 is a T-shaped structure as a whole, a plug-in groove 401 is provided on the side wall of the blade 4 close to the plug-in block 5, and the plug-in groove 401 is connected to the plug-in groove 401. The connecting block 5 is adapted, and the top of each blade 4 near the end of the plug-in block 5 is detachably connected with a mounting frame 6. The side wall surface of the mounting frame 6 away from the plug-in block 5 is provided with a first through hole 601. The inner cavity of the first through hole 601 is slidably provided with a pulling rod 602 that matches the first through hole 601. The end of the pulling rod 602 located on the outside of the mounting frame 6 is fixedly connected with a pulling ring 603 of a ring structure. By setting the pulling ring 603 into a ring-shaped structure, it is more convenient to pull, saving time and effort. A return spring 604 is sleeved on the moving rod 602 and located in the inner cavity of the installation frame 6. A limit plate 605 is fixedly connected to one end of the pull rod 602 and located in the inner cavity of the installation frame 6. The wall surface of the limit plate 605 close to the installation frame 6 is in contact with the inner cavity wall surface of the installation frame 6. A second through hole 606 is opened on the side wall surface of the installation frame 6 away from the first through hole 601. The second through hole 606 corresponds to the position of the first through hole 601. The inner cavity of the second through hole 606 is penetrated by a plug-in rod 607, one end of the plug-in rod 607 close to the limit plate 605 is fixedly connected to the central wall of the limit plate 605, and the upper and lower walls of the limit plate 605 are in contact with the upper and lower walls of the inner cavity of the installation frame 6. This design avoids the limit plate 605 shaking around in the inner cavity of the installation frame 6 when the pulling ring 603 is pulled. The plug-in block 5 is close to the side wall of the installation frame 6 and is provided with a plug-in hole 501 at a position corresponding to the plug-in rod 607, and the plug-in hole 501 is adapted to the plug-in rod 607.

[0024] The working principle of this utility model:

[0025] During use, when the blade 4 needs to be disassembled and replaced, remove the top plate 2, pull the pulling ring 603 to pull the pulling rod 602 outward, at this time, the limiting plate 605 will squeeze and contract the reset spring 604, and the plug-in rod 607 approaches the pulling ring 603 until the plug-in rod 607 is moved out of the inner cavity of the plug-in hole 501, thereby releasing the limit on the plug-in hole 501 and sliding the blade 4 out of the plug-in block 5 from bottom to top, thereby removing the blade 4 for replacement.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.
